Global crisis can be overcome in 18 months: APEC

Pacific Rim nations assured the world that the global financial crisis can be quelled in 18 months, but provided few details of how they expect that to happen - or how their governments can help.The 21 economies, which represent more than half of the world's productive power, also pledged during a two-day summit not to erect new protectionist barriers for the next year, and to jump-start stalled World Trade Organization talks.The main accomplishment of the Asia-Pacific Economic Cooperation forum was a widening of support for the Washington Declaration made last weekend by major economies that pledged to maintain free trade despite pressures to protect domestic industries.

The leaders voiced confidence that the crisis could be resolved by mid-2010, though they did not go much beyond the steps outlined in the Group of 20 summit in Washington.

"We are convinced that we can overcome this crisis in a period of 18 months," the leaders said in a statement. "We have already taken urgent and extraordinary steps to stabilize our financial sectors and strengthen economic growth."The reassuring words were added early Sunday to a declaration the leaders had signed off on the previous day. Delegates from several countries said the changes were made overnight at the request of the summit's host, Peruvian President Alan Garcia."We have agreed that this meeting produce a clear and firm statement that breaks the vicious cycle of anguish and uncertainty," Garcia said Sunday. "We - united as the world's peoples, governments and businesses - are going to beat the crisis."

The 18-month timeline fits with a calculation by the International Monetary Fund, which forecast developed economies would grow barely 0.1 per cent in 2009, and that the world would emerge from the crisis the following year.

But some delegates and analysts were skeptical that the timetable was much more than wishful thinking, and some leaders distanced themselves from the language. Mexican President Felipe Calderon described the date as more of an estimate than a prediction.Canadian Prime Minister Stephen Harper went a step further."I think it would be speculative to commit to that kind of timeline," he said.And Dan Price, an aide to George W. Bush, said the US president thinks the global economy can be fixed even faster.

"That particular sentence was added by the president of Peru as the chair," Price said aboard Air Force One. "Certainly, some in the region may think that recovery may take 18 months. President Bush...

Ramsey Cascades

Ramsey Cascades is the tallest waterfall in the park and one of the most spectacular. Water drops 100 feet over rock outcroppings and collects in a small pool where numerous well-camouflaged salamanders can be found.

The trail to the waterfall gains over 2,000' in elevation over its 4 mile course and the 8-mile roundtrip hike is considered strenuous in difficulty. It follows rushing rivers and streams for much of its length. The last 2 miles pass through old-growth cove hardwood forest with large tuliptrees, basswoods, silverbells, and yellow birches.Do not attempt to climb to the top of the falls. Several people have been killed trying to do so.

Access Trail: Ramsey Cascades Trail (Tennessee)Trailhead: Drive six miles east of Gatlinburg on Highway 321 and turn at the Greenbrier entrance to the park. Follow the signs 4.7 miles to the trailhead.

Ulcerative Colitis

Also called: Colitis, Distal colitis, Pancolitis, Ulcerative proctitis
Ulcerative colitis is a disease that causes ulcers in the lining of the rectum and colon. It is one of a group of diseases called inflammatory bowel disease. Ulcers form where inflammation has killed the cells that usually line the colon.

Ulcerative colitis can happen at any age, but it usually starts between the ages of 15 and 30. It tends to run in families. The most common symptoms are pain in the abdomen and bloody diarrhea. Other symptoms may include anemia, severe tiredness, weight loss, loss of appetite, bleeding from the rectum, sores on the skin and joint pain. Children with the disease may have growth problems.

About half of people with ulcerative colitis have mild symptoms. Several types of drugs can help control ulcerative colitis. Some people have long periods of remission, when they are free of symptoms. In severe cases, doctors must remove the colon.

Ficus

Ficus is a genus of about 850 species of woody trees, shrubs, vines, epiphytes, and hemi epiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The so-called Common Fig (F. carica) is a temperate species from the Middle East and eastern Europe (mostly Ukraine), which has been widely cultivated from ancient times for its fruit, also referred to as figs.Figs occupy a wide variety of ecological niches. Take, for example, the Common Fig, a small temperate deciduous tree whose fingered fig leaf is well-known in art and iconography; or the Weeping Fig (F. benjamina) a hemi-epiphyte with thin tough leaves on pendulous stalks adapted to its rain forest habitat; or the rough-leaved sandpaper figs from Australia; or the Creeping Fig (F. pumila), a vine whose small, hard leaves form a dense carpet of foliage over rocks or garden walls. Moreover, figs with different plant habits have undergone adaptive radiation in different biogeographic regions, often leading to very high levels of alpha diversity. In the tropics, it is quite common to find that Ficus is the most species-rich plant genus in a particular forest. In Asia as many as 70 or more species can co-exist.

A fig "fruit" is derived from a specially adapted type of inflorescence (an arrangement of multiple flowers). In this case, it is an involuted, nearly closed receptacle with many small flowers arranged on the inner surface. Thus the actual flowers of the fig are unseen unless the fig is cut open.In Bengali, where the Common Fig is called dumur, it is referenced in a proverb: tumi jeno dumurer phool hoe gele ("You have become [invisible like] the dumur flower").

The syconium often has a bulbous shape with a small opening (the ostiole) at the outward end that allows access to pollinators. The flowers are pollinated by very small wasps that crawl through the opening in search of a suitable place to lay eggs. Without this pollinator service fig trees cannot reproduce by seed. In turn, the flowers provide a safe haven and nourishment for the next generation of wasps. This accounts for the frequent presence of wasp larvae in the fruit. Technically, a fig fruit proper would be one of the many tiny mature, seed-bearing flowers found inside one fig - if you cut open a fresh fig, the flowers will appear as fleshy "threads", each bearing a single seed inside.

The fig plants can be monoecious (hermaphrodite) or dioecious (hermaphrodite and female).

'Hamilton has just got to use his brain'

The Formula One world championship is poised for a thrilling climax with three drivers in with a chance of winning with two races to go.

Lewis Hamilton of McLaren heads into Sunday's race in China with a five-point championship lead over Ferrari's Felipe Massa, with BMW Sauber's Robert Kubica a further seven adrift.

On paper, Hamilton should be a strong favourite, and Kubica - whose car is off the pace of the Ferrari and McLaren - should have no chance.

But the Englishman's position is not as strong as it might at first appear.

And after a season of topsy-turvy results and high-profile errors, it is clear anything could happen - especially when Hamilton appears to have more enemies out on the track than he does in the title battle.

We assess the positions of each of the three contenders.

Houston

Houston is the fourth-largest city in the United States of America and the largest city within the state of Texas. As of the 2006 U.S. Census estimate, the city has a population of 2.2 million within an area of 600 square miles (1,600 km²). Houston is the seat of Harris County and the economic center of the Houston–Sugar Land–Baytown metropolitan area—the sixth-largest metropolitan area in the U.S. with a population of around 5.6 million.

Houston was founded on August 30, 1836 by brothers Augustus Chapman Allen and John Kirby Allen on land near the banks of Buffalo Bayou. The city was incorporated on June 5, 1837 and named after then-President of the Republic of Texas—former General Sam Houston—who had commanded at the Battle of San Jacinto, which took place 25 miles (40 km) east of where the city was established. The burgeoning port and railroad industry, combined with oil discovery in 1901, has induced continual surges in the city's population. In the mid-twentieth century, Houston became the home of the Texas Medical Center—the world's largest concentration of healthcare and research institutions—and NASA's Johnson Space Center, where the Mission Control Center is located.

Houston's economy has a broad industrial base in the energy, manufacturing, aeronautics, transportation, and health care sectors; only New York City is home to more Fortune 500 headquarters in the city limits. Commercially, Houston is ranked as a gamma world city, and the area is a leading center for building oilfield equipment. The Port of Houston ranks first in the United States in international waterborne tonnage handled and second in total cargo tonnage handled. The city has a multicultural population with a large and growing international community. It is home to many cultural institutions and exhibits—attracting more than 7 million visitors a year to the Houston Museum District. Houston has an active visual and performing arts scene in the Theater District and is one of few U.S. cities that offer year-round resident companies in all major performing arts

Indian National Bird

The Indian peacock, Pavo cristatus, the national bird of India, is a colourful, swan-sized bird, with a fan-shaped crest of feathers, a white patch under the eye and a long, slender neck. The male of the species is more colourful than the female, with a glistening blue breast and neck and a spectacular bronze-green train of around 200 elongated feathers. The female is brownish, slightly smaller than the male and lacks the train. The elaborate courtship dance of the male, fanning out the tail and preening its feathers is a gorgeous sight.

Our Oceans Are In Trouble:

What is the state of the ocean today?

It's actually very bad. It's probably worse in many ways than the state of conservation on land, but we don't think about it because we don't live in it.

Basically it comes down to what we put into the atmosphere and ocean and what we take out of the ocean. What we put into the atmosphere is carbon dioxide, which makes the ocean hotter. And when it dissolves in the oceans themselves, it makes them more acidic. From the land, you're getting all this runoff into the oceans—vast amounts of nutrients associated with excess fertilizer, pesticides, industrial waste, waste from cars and city streets. There's a lot of stuff that fertilizes the ocean and causes bacteria and other slimy stuff to proliferate, plus things that actually poison the ocean.

We also have the massive scale of fisheries. We're pulling out the tops of the food chain. Most of the big fish in the ocean are already gone. We've also strip-mined the bottom of the sea floor with trawls.We've basically created a massive disturbance to the ocean, which is resulting in collapsing ecosystems, failing fisheries, toxic blooms.

When did scientists realize the damage we're causing the ocean?

In the last 50 years, things have really deteriorated. People have had some impact for a long time, but the ocean can suffer a certain amount of assault from human activity and not have a major problem with it. Now everything is increasing. Carbon dioxide is increasing dramatically. Industrial fisheries, since about the 1950s, have increased dramatically.

BBC plans to double its output made in Wales

THE BBC last night announced ambitious plans to double the proportion of network productions made in Wales, with Crimewatch coming to Cardiff in 2011 and Casualty likely to follow a year later.Coming just a week after ITV’s decision to slash programme making in Wales, the news is a welcome boost for the broadcasting industry.

In a speech to the Royal Television Society last night, BBC executive Jana Bennett also announced that, for the very first time, a network commissioning executive will be based in Cardiff to help build on the success of the independent production sector.The shifting of resources to Wales ties in with the BBC’s commitment to better reflect the diversity of creative talent around the UK.

In 2006 and 2007 the proportion of spend outside London increased by 15%. Last year the BBC, affectionately known as Auntie, spent £300m outside London.Ms Bennett’s announcement was said to represent the corporation’s determination to build a large-scale, sustainable production centre in Wales, focused on drama, factual and music content.It would enable BBC Wales and its partners in the independent sector to build on the success of existing network programmes such as Doctor Who and Torchwood.

NASA Space Probe to Fly Over Mercury, Closest Planet to Sun:


A U.S. spacecraft will fly over Mercury next week to photograph the planet closest to the sun, in the second of three passes, NASA said.

The Messenger probe will take more than 1,200 pictures and collect data from the smallest planet in the solar system when it swings 125 miles (200 kilometers) above Mercury's cratered surface on Oct. 6, the National Aeronautics and Space Administration said a statement on its Web site yesterday.

The 2,442-pound (1,107 kilogram) probe is due to pass the planet three times before settling into orbit in March 2011, NASA said. Messenger was launched in August 2004 at a cost of $286 million. It first flew past in January and will make its final pass in September 2009.

``The results from Messenger's first flyby of Mercury resolved debates that are more than 30 years old,'' Sean Solomon, the mission's principle investigator from the Carnegie Institution of Washington, said in the statement. ``The second encounter will uncover even more information about the planet.''

The spacecraft is more than halfway through a 4.9 billion- mile journey that includes more than 15 trips around the sun before entering orbit around Mercury, NASA said. The probe is designed to improve scientists' understanding of how Earth, Venus and Mars were formed, and their interactions with the sun.

The January flyby showed that volcanic eruptions produced many of Mercury's plains and that its magnetic field appears to be generated in a molten iron core, according to the space agency.

The second flyby may bring more information about the particles located around the planet's magnetic field, according to NASA, which said the probe will also chart Mercury's topography.

has a diameter of about 3,000 miles, less than half the diameter of Earth and is 36 million miles from the sun.

Before Messenger, the only other craft to visit Mercury was Mariner 10, which passed the planet three times in 1974 and 1975.

Cash drive launched so delicate mummy can finally see the light

A public appeal is to be launched in March so that Hull's Egyptian mummy, which recently starred in a TV programme, can come out from the dark. The 2,700 year old mummy belonging to Hull Museums is so fragile that it cannot be put on display and has been kept in storage for 60 years.

But because of the huge interest shown in Channel 5's programme entitled 'The True Curse of the Mummy', museum officials want Hull people to have a chance to come face to face with the preserved remains, now thought to be the inspiration behind a whole genre of horror stories.

But they need people to dig into their pockets. Money is needed to pay for cleaning and conserving the mummy and another one in Hull's collection, so they can be exhibited without causing their condition to deteriorate further.

Anaerobic biodegradation of pollutants

Anaerobic microbial mineralization of recalcitrant organic pollutants is of great environmental significance and involves intriguing novel biochemical reactions. In particular, hydrocarbons and halogenated compounds have long been doubted to be degradable in the absence of oxygen, but the isolation of hitherto unknown anaerobic hydrocarbon-degrading and reductively dehalogenating bacteria during the last decades provided ultimate proof for these processes in nature. Many novel biochemical reactions were discovered enabling the respective metabolic pathways, but progress in the molecular understanding of these bacteria was rather slow, since genetic systems are not readily applicable for most of them. However, with the increasing application of genomics in the field of environmental microbiology, a new and promising perspective is now at hand to obtain molecular insights into these new metabolic properties. Several complete genome sequences were determined during the last few years from bacteria capable of anaerobic organic pollutant degradation. The ~4.7 Mb genome of the facultative denitrifying Aromatoleum aromaticum strain EbN1 was the first to be determined for an anaerobic hydrocarbon degrader (using toluene or ethylbenzene as substrates). The genome sequence revealed about two dozen gene clusters (including several paralogs) coding for a complex catabolic network for anaerobic and aerobic degradation of aromatic compounds.

Nootropic
Nootropics, popularly referred to as "smart drugs", "smart nutrients", "cognitive enhancers" and "brain enhancers", are a class of drugs that improve impaired human cognitive abilities (the functions and capacities of the brain). The term covers a broad range of substances including drugs, nutrients and herbs that have purported cognitive enhancing effects.

The word nootropic was coined in 1964 by the Romanian Dr. Corneliu E. Giurgea, derived from the Greek words noos, or "mind," and tropein meaning "to bend/turn". Typically, nootropics are alleged to work by altering the availability of the brain's supply of neurochemicals (neurotransmitters, enzymes, and hormones), by improving the brain's oxygen supply, or by stimulating nerve growth. However the efficacy of alleged nootropic substances in most cases has not been conclusively determined. This is complicated by the difficulty of defining and quantifying cognition and intelligence.

Biotechnology

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine. The United Nations Convention on Biological Diversity defines biotechnology as:
Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.

Biotechnology is often used to refer to genetic engineering technology of the 21st century, however the term encompasses a wider range and history of procedures for modifying biological organisms according to the needs of humanity, going back to the initial modifications of native plants into improved food crops through artificial selection and hybridization. Bioengineering is the science upon which all biotechnological applications are based. With the development of new approaches and modern techniques, traditional biotechnology industries are also acquiring new horizons enabling them to improve the quality of their products and increase the productivity of their systems.

Strapdown systems

Lightweight digital computers permit the system to eliminate the gimbals, creating "strapdown" systems, so called because their sensors are simply strapped to the vehicle. This reduces the cost, eliminates gimbal lock, removes the need for some calibrations, and increases the reliability by eliminating some of the moving parts. Angular rate sensors called "rate gyros" measure how the angular velocity of the vehicle changes.

A strapdown system has a dynamic measurement range several hundred times that required by a gimbaled system. That is, it must integrate the vehicle's attitude changes in pitch, roll and yaw, as well as gross movements. Gimballed systems could usually do well with update rates of 50 to 60 updates per second. However, strapdown systems normally update about 2000 times per second. The higher rate is needed to keep the maximum angular measurement within a practical range for real rate gyros: about 4 milliradians. Most rate gyros are now laser interferometers.

The data updating algorithms ("direction cosines" or "quaternions") involved are too complex to be accurately performed except by digital electronics. However, digital computers are now so inexpensive and fast that rate gyro systems can now be practically used and mass-produced. The Apollo lunar module used a strapdown system in its backup Abort Guidance System (AGS).

Strapdown systems are nowadays commonly used in commercial and tactical applications (arcraft, missiles, etc). However they are still not widespread in applications where superb accuracy is required (like submarine navigation or strategic ICBM guidance).

Implicit Web

The Implicit Web is a concept coined in 2007 to denote web sites which specialize in the synthesis of personal information gleaned from the Internet into a single, coherent picture of user behavior. Implicit data may include clickstream information, media consumption habits, location tracking or any data generated without "explicit" input from a user. Presumed advantages of implicit data include accuracy, ease of input and comprehensiveness.

The term Implicit Web was popularized by the technology investors Josh Kopelman, Fred Wilson, and Brad Feld.

Google Earth Plus

Google Earth can be upgraded to a Plus edition for a $20 annual subscription fee. Google Earth Plus is an individual-oriented paid subscription upgrade to Google Earth and adds the following features:

* GPS integration: read tracks and waypoints from a GPS device. A variety of third party applications have been created which provide this functionality using the basic version of Google Earth by generating KML or KMZ files based on user-specified or user-recorded waypoints. However, Google Earth Plus provides direct support for the Magellan and Garmin product lines, which together hold a large share of the GPS market. The Linux version of the Google Earth Plus application does not include any GPS functionality.
* Higher resolution printing.
* Customer support via email.
* Data importer: read address points from CSV files; limited to 100 points/addresses. A feature allowing path and polygon annotations, which can be exported to KML, was formerly only available to Plus users, but was made free in version 4.0.2416.
* Higher data download speeds

Network telescope

A network telescope (also known as a darknet, internet motion sensor or black hole) is an internet system that allows one to observe different large-scale events taking place on the Internet. The basic idea is to observe traffic targeting the dark (unused) address-space of the network. Since all traffic to these addresses is suspicious, one can gain information about possible network attacks (random scanning worms, and DDoS backscatter) as well as other misconfigurations by observing it.

The resolution of the Internet telescope is dependent on the number of dark addresses it monitors. For example, a large Internet telescope that monitors traffic to 16,777,216 addresses (a /8 Internet telescope in IPv4), has a higher probability of observing a relatively small event than a smaller telescope that monitors 65,536 addresses (a /16 Internet telescope).

A variant of a network telescope is a sparse darknet, or greynet, consisting of a region of IP address space that is sparsely populated with 'darknet' addresses interspersed with active (or 'lit') IP addresses.

Object-relational database

An object-relational database (ORD) or object-relational database management system (ORDBMS) is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. In addition, it supports extension of the data model with custom data-types and methods.

One aim for this type of system is to bridge the gap between conceptual data modeling techniques such as Entity-relationship diagram (ERD) and object-relational mapping (ORM), which often use classes and inheritance, and relational databases, which do not directly support them.

Another, related, aim is to bridge the gap between relational databases and the object-oriented modeling techniques used in programming languages such as Java (programming language), C++ or C#. However, a more popular alternative for achieving such a bridge is to use a standard relational database systems with some form of ORM software.

Software transactional memory
In computer science, software transactional memory (STM) is a concurrency control mechanism analogous to database transactions for controlling access to shared memory in concurrent computing. It functions as an alternative to lock-based synchronization, and is typically implemented in a lock-free way. A transaction in this context is a piece of code that executes a series of reads and writes to shared memory. These reads and writes logically occur at a single instant in time; intermediate states are not visible to other (successful) transactions. The idea of providing hardware support for transactions originated in a 1986 paper and patent by Tom Knight. The idea was popularized by Maurice Herlihy and J. Eliot B. Moss. In 1995 Nir Shavit and Dan Touitou extended this idea to software-only transactional memory (STM). STM has recently been the focus of intense research and support for practical implementations is growing.

Optimization

Optimization or optimality is a term that may refer to:

* Optimization (mathematics), trying to find maxima and minima of a function
* Optimization (computer science), improving a system to reduce runtime, bandwidth, memory requirements, or other property of a system; in particular
o Compiler optimization, improving the performance or efficiency of compiled code
* Search engine optimization, in internet marketing, methodologies aimed at improving the ranking of a website in search engine listings
* Process optimization, in business and engineering, methodologies for improving the efficiency of a production process
* Product optimization, in business and marketing, methodologies for improving the quality and desirability of the current product or a product concept
* Optimality theory in linguistics.
* Optimal classification, a process which arranges classification element attributes in an order which minimizes the number of queries necessary to identify any particular element.

Blacklisting

Attempts to stop spam by blacklisting sender's IP addresses still allows a small percentage through. Most IP addresses are dynamic, i.e. they are frequently changing. An ISP, or any organization directly connected to the Internet, gets a block of real Internet addresses when they register in the DNS. Within that block, they assign individual addresses to customers as needed. A dial-up customer may get a new IP address each time they connect. By the time that address appears on blacklists all over the world, the spammer will have new addresses for the next run. There are 4 billion possible IPv4 addresses on the Internet. The game of keeping up with these rapidly changing IP addresses has been facetiously called "whack-a-mole".

So called policy lists are black lists that contain IP addresses on a preventive basis. An IP address can be listed therein even if no spam has ever been sent from it, because it has been variously classified as a dial-up address, end-user address, or residential address, with no formal definition of such classification schemes. Not requiring evidence of spam for each enlisted address, these lists can collect a greater number of addresses and thus block more spam. However, the policies devised are not authoritative, since they have not been issued by the legitimate user of an IP address, and the resulting lists are therefore not universally accepted.

Spyware

Spyware is computer software that is installed surreptitiously on a personal computer to intercept or take partial control over the user's interaction with the computer, without the user's informed consent.

While the term spyware suggests software that secretly monitors the user's behavior, the functions of spyware extend well beyond simple monitoring. Spyware programs can collect various types of personal information, such as Internet surfing habit, sites that have been visited, but can also interfere with user control of the computer in other ways, such as installing additional software, redirecting Web browser activity, accessing websites blindly that will cause more harmful viruses, or diverting advertising revenue to a third party. Spyware can even change computer settings, resulting in slow connection speeds, different home pages, and loss of Internet or other programs. In an attempt to increase the understanding of spyware, a more formal classification of its included software types is captured under the term privacy-invasive software.

Types of spam

Spam has several definitions, varying by the source.

* Unsolicited bulk e-mail (UBE)—unsolicited e-mail, sent in large quantities.
* Unsolicited commercial e-mail (UCE)—this more restrictive definition is used by regulators whose mandate is to regulate commerce, such as the U.S. Federal Trade Commission.
* Any email message that is fraudulent.
* Any email message where the sender’s identity is forged, or messages sent though unprotected SMTP servers, unauthorized proxies, or botnets (see Theft of service below).

Cybernetics

Cybernetics is the interdisciplinary study of the structure of complex systems, especially communication processes, control mechanisms and feedback principles. Cybernetics is closely related to control theory and systems theory.

Example of cybernetic thinking. On the one hand a company is approached as a system in an environment. On the other hand cybernetic factory can be modeled as a control system.

Example of cybernetic thinking. On the one hand a company is approached as a system in an environment. On the other hand cybernetic factory can be modeled as a control system.

Contemporary cybernetics began as an interdisciplinary study connecting the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology and neuroscience in the 1940s.

Other fields of study which have influenced or been influenced by cybernetics include game theory, system theory (a mathematical counterpart to cybernetics), psychology (especially neuropsychology, behavioral psychology, cognitive psychology), philosophy, and architecture.

Cellular automaton

A cellular automaton (plural: cellular automata) is a discrete model studied in computability theory, mathematics, theoretical biology and microstructure modeling. It consists of a regular grid of cells, each in one of a finite number of states. The grid can be in any finite number of dimensions. Time is also discrete, and the state of a cell at time t is a function of the states of a finite number of cells (called its neighborhood) at time t − 1. These neighbors are a selection of cells relative to the specified cell, and do not change (though the cell itself may be in its neighborhood, it is not usually considered a neighbor). Every cell has the same rule for updating, based on the values in this neighbourhood. Each time the rules are applied to the whole grid a new generation is created.

Conceptual system
A conceptual system is simply a model. There is no limitations on this kind of model whatsoever except those of human imagination. If there is an experimentally verified correspondence between a conceptual system and a physical system then that conceptual system models the physical system. "values, ideas, and beliefs that make up every persons view of the world": that is a model of the world; a conceptual system that is a model of a physical system (the world). The person who has that model is a physical system.

In psychology and social work, when they talk about a conceptual system, they are referring to some person's model of the world, but if they try to understand that model, they end up making a model of that model, which is just a model of the person's behavior. In any case, this is exactly the purpose of the general term "conceptual systems".

Systems engineering

Systems engineering is an interdisciplinary field of engineering, that focuses on the development and organization of complex artificial systems. Systems engineering is defined by INCOSE as "a branch of engineering whose responsibility is creating and executing an interdisciplinary process to ensure that customer and stakeholder's needs are satisfied in a high quality, trustworthy, cost efficient and schedule compliant manner throughout a system's entire life cycle, from development to operation to disposal. This process is usually comprised of the following seven tasks: State the problem, Investigate alternatives, Model the system, Integrate, Launch the system, Assess performance, and Re-evaluate. The systems engineering process is not sequential: the tasks are performed in a parallel and iterative manner."

Concurrent Versions System

In the field of software development, the Concurrent Versions System (CVS), also known as the Concurrent Versioning System, provides a version control system based on open-source code. Version control system software keeps track of all work and all changes in a set of files, and allows several developers (potentially widely separated in space and/or time) to collaborate. Dick Grune developed CVS in the 1980s. CVS has become popular in the open source software world and is released under the GNU General Public License.

Solutrean hypothesis

The Solutrean hypothesis proposes that stone tool technology of the Solutrean culture in prehistoric Europe may have later influenced the development of the Clovis tool-making culture in the Americas, and that peoples from Europe may have been among the earliest settlers in the Americas. First proposed in 1998, its key proponents include Dennis Stanford of the Smithsonian Institution and Bruce Bradley of the University of Exeter.

In this hypothesis, peoples associated with the Solutrean culture migrated from Ice Age Europe to North America, bringing their methods of making stone tools with them and providing the basis for later Clovis technology found throughout North America. The hypothesis rests upon particular similarities in Solutrean and Clovis technology that have no known counterparts in Eastern Asia, Siberia or Beringia, areas from which or through which early Americans are known to have migrated.

Green travel

Green travel is a method for people to travel while reducing their impact on the environment.

Some forms of green travel include:

* Use of walking, cycling, and public transport instead of car use, when possible.

* Use of biodiesel fuels.

* Taking advantage of ridesharing and carpools

* Booking travel through a green website like Green Travel by RezHub.com . They not only offers bookings with green travel suppliers (hotels, hybrid car rentals, carbon offstting), they also donate a portion of all revenue to a green organization.

* Stay at a green hotel or lodge.

Transformation of culture

Transformation of culture, or cultural change, refers to the dynamic process whereby the living cultures of the world are changing and adapting to external or internal forces. This process is occurring within Western culture as well as non-Western and indigenous culture of the world. Forces which contribute to the cultural change described in this article include: colonization, globalization, advances in communication, transportation and infrastructure improvements, and military expansion.

Evolutionary prototyping

Evolutionary Prototyping (also known as breadboard prototyping) is quite different from Throwaway Prototyping. The main goal when using Evolutionary Prototyping is to build a very robust prototype in a structured manner and constantly refine it. "The reason for this is that the Evolutionary prototype, when built, forms the heart of the new system, and the improvements and further requirements will be built

When developing a system using Evolutionary Prototyping, the system is continually refined and rebuilt.

"…evolutionary prototyping acknowledges that we do not understand all the requirements and builds only those that are well understood."

Life cycle of a relational database

The life cycle of a relational database is the cycle of development and changes that a database goes through during the course of its life. The cycle typically consists of several stages. There is possibility that the database designer/developer can go back to any of the previous stages. This represents an admission that a full understanding of a problem and its solution is likely to evolve as the various stages of design and implementation proceed. The typical eleven stages involved in the life cycle of a relational database are as follows:

BE AWARE THIS IS ONLY ONE VERSION, MULTIPLE DIFFERING VERSIONS EXIST

1. The designer must try to obtain as complete as possible an understanding of the real world problem that is going to be helped by the introduction of a database. This understanding of the nature of the problem and the constraints and outline feasible solutions is often performed using some systems analysis methodology.
2. The entity relationship diagram is drawn, and this diagram in its modified form serves as an essential part of the logical schema. Attributes of the entity types so produced are then added. Primary and foreign keys are specified.
3. Normalization is used to check the entity-relationship model. Some splitting and even recombination of entity types may result from normalization and the entity relationship model will have to be updated accordingly. The entity relationship model and the table definitions resulting from normalization should be consistent.
4. Set of Table(s) definition for the required schema is finalized.
5. The database tables are created. Primary, Foreign keys, database constraints and database integrity rules are specified at this stage.
6. At this stage, the file organization is performed. File organization is the way the database relations are to be stored on the storage medium. The file organization is decided on the basis of maximum speed of access, the type of access required and storage space considerations. There are two factors to consider; firstly how the records are to be physically mapped onto the storage medium, and secondly which indexes are to be used and if so, which fields (attributes, columns) are to be indexed. Indexes are designed to increase the speed of access to required records. Views can also be defined at this stage. Views are used to limit access to parts of database only, when used in conjunction with access privileges. Views also make programming simpler.
7. The designer will be able to design the required queries at this stage. The designer should have a good idea of the main types of query and reports the database will have to accommodate.
8. At this stage, application screens are designed. The application screens are used to capture the input information that will be kept in the database. Screen design is partially determined by the data items that must be input and output by particular applications and partially in human-computer interface terms. When designing screens, special consideration is given to the suggestions given by the application end users. There are published standards which can be exactly followed for screens design or organization can develop their own screen design standards as per their requirements.
9. Report design is another area where input from users is paramount. They will specify what they want to see on the reports and the format of the reports and in the case of regular reports, when they should be produced. Now-a-days most of the application design tools provide easy to use friendly tools for quick reports development. e.g. report builder in Oracle, Crystal Reports, R&R Report Writer etc.
10. Testing is performed at this stage. Application screens, various functions offered by the application screens, data validations through screens and reports are tested and it serves as the ultimate test of the correctness of the database schema and the viability of the system as a whole. It is recommended to create a test database separate of the production database. The test database will be useful for testing any schema changes and new and modified application before applying the changes to the production (live) database. Careful testing of the system before handover will minimize the expense of later modifications to the schema and major applications.
11. The final stage is Handover. This is the stage where the users receive the finished database and applications and begin data entry. In practice, it is likely that the core of the system will be handed over to users and later extensions to the system will be implemented.

4th Dimension (Software)


4th Dimension (or 4D, or Silver Surfer, as it was known during early development) is a relational database management system and IDE developed by Laurent Ribardière in 1984. In 1993, 4D Server, the client/server version of 4th Dimension was introduced and since 1995, 4D has supported both the Microsoft Windows and Apple Macintosh operating systems.

The 4D product line has since expanded to an SQL front-end, integrated compiler and several productivity plug-ins and interfaces. Some of the more useful plug-ins include 4D Write (a word processor), 4D Draw (to draw shapes), 4D View (somewhat like a spreadsheet, but with extra functionality) and 4D Internet Commands (which let you add all sorts of Internet related functionality to a database). There are also over 100 third-party plugins, free and commercial.

Application-level gateway

In the context of computer networking, an application-level gateway [1] (also known as ALG or application layer gateway) consists of a security component that augments a firewall or NAT employed in a computer network. It allows customized NAT traversal filters to be plugged into the gateway to support address and port translation for certain application layer "control/data" protocols such as FTP, BitTorrent, SIP, RTSP, file transfer in IM applications etc. In order for these protocols to work through NAT or a firewall, either the application has to know about an address/port number combination that allows incoming packets, or the NAT has to monitor the control traffic and open up port mappings (firewall pinhole) dynamically as required. Legitimate application data can thus be passed through the security checks of the firewall or NAT that would have otherwise restricted the traffic for not meeting its limited filter criteria.

Waterfall model
The waterfall model is a sequential software development model (a process for the creation of software) in which development is seen as flowing steadily downwards (like a waterfall) through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance. The origin of the term "waterfall" is often cited to be an article published in 1970 by Winston W. Royce (1929–1995),[1] although Royce did not use the term "waterfall" in this article. Ironically, Royce was actually presenting this model as an example of a flawed, non-working model (Royce 1970).

Field emission display (FED)

A field emission display (FED) is a type of flat panel display using field emitting cathodes to bombard phosphor coatings as the light emissive medium.

Field emission displays are very similar to cathode ray tubes, however they are only a few millimeters thick. Instead of a single electron gun, a field emission display (FED) uses a large array of fine metal tips or carbon nanotubes (which are the most efficient electron emitters known), with many positioned behind each phosphor dot, to emit electrons through a process known as field emission. Because of emitter redundancy, FEDs do not display dead pixels like LCDs even if 20% of the emitters fail. Sony is researching FED because it is the flat-panel technology that comes closest to matching the picture of a CRT.

Methods for solids

Computational chemical methods can be applied to solid state physics problems. The electronic structure of a crystal is in general described by a band structure, which defines the energies of electron orbitals for each point in the Brillouin zone. Ab initio and semi-empirical calculations yield orbital energies, therefore they can be applied to band structure calculations. Since it is time-consuming to calculate the energy for a molecule, it is even more time-consuming to calculate them for the entire list of points in the Brillouin zone.

Satur

Saturn (pronounced /'sæt?n/) is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Along with the planets Jupiter, Uranus, Neptune it is classify as a gas giant (also known as a Jovian planet, after the planet Jupiter). It was named after the Roman god Saturnus, equate to the Greek Kronos (the Titan father of Zeus) and the Babylonian Ninurta. Saturn's sign represents the god's sickle (Unicode: ?), The day in the week Saturday gets its name from the planet.

The planet Saturn is calm of hydrogen, with small proportions of helium and trace elements. The interior consists of a small core of rock and ice, bounded by a thick layer of metallic hydrogen and a gaseous outer layer. The outer atmosphere is normally bland in appearance, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h, considerably faster than those on Jupiter. Saturn has a planetary magnetic field intermediate in strength among that of Earth and the more powerful field around Jupiter.

Pineapple

The pineapple (Ananas comosus) is a tropical plant and fruit (multiple), inhabitant to Uruguay, Brazil, Puerto Rico, or Paraguay. It is a medium tall (1–1.5 m) herbaceous perennial plant with 30 or more trough-shaped and pointed leaves 30–100 cm long, nearby a thick stem. The pineapple is an illustration of a multiple fruit: multiple, spirally-arranged flowers along the axis each make a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit. The leaves of the cultivar 'Smooth Cayenne' mostly lack spines apart from at the leaf tip, but the cultivars 'Spanish' and 'Queen' have large spines along the leaf margins. Pineapples are the only bromeliad fruit in extensive cultivation. It is one of the most commercially important plants which take out Crassulacean acid metabolism, or CAM photosynthesis.

Fixed asset

Fixed asset also familiar as property, plant, and equipment (PP&E), is a term used in accountancy for assets and goods which cannot easily be converted into cash. This can be differing with current assets such as cash or bank accounts, which are describe as liquid assets. In most cases, only tangible assets are also called as fixed.

It usually includes items such as land and buildings, motor vehicles, furniture, office tools, computers, fixtures and fittings, and plant and machinery. These frequently receive favorable tax treatment (deprecation allowance) over short-term assets because they depreciate in excess of time.

Soil

Soil, comprising the pedosphere, is located at the border of the lithosphere with the biosphere, atmosphere, and hydrosphere. It consists of mineral, organic matter, as well as living organisms. Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological, and anthropogenic process on soil parent material ensuing in the configuration of soil horizons.
Soil is our most important natural resources because of its position in the landscape and its dynamic, physical, chemical, and biologic functions. While the general concept of soil is well recognized, the definition of soil varies, according to the viewpoint of the discipline or occupation by means of soil as a resource.

Inkjet printer


Inkjet printers activate by propelling various size (mostly tiny) droplets of liquid or molten material (ink) onto almost any media. They are the most common type of computer printer for the wide-ranging consumer [citation needed] due to their low cost, high quality of output, capability of printing in vivid color, and ease of use.

Forest

A forest is a region with a high thickness of trees (or, historically, a wooded area set aside for hunting). There are many definitions of a forest, based on a variety of criteria. These plant communities cover large areas of the globe and function as animal habitats, hydrologic flow modulators, and soil conservers, comprise one of the most important aspects of the Earth's biosphere. Although often thought of as carbon dioxide sinks, mature forests are approximately carbon neutral with only disturbed and young forests acting as carbon sinks. Nonetheless mature forests do play a significant role in the global carbon cycle as stable carbon pools, and clearance of forests leads to an increase of atmospheric carbon dioxide levels.
Forests can be found in all regions talented of sustaining tree growth, at altitudes up to the tree-line, except where natural fire frequency is too high, or where the environment has been impaired by natural processes or by human activities.

Batsman

A batsman in the sport of cricket is, depending on context: Any players will perform for batting. A player whose expert in the game is batting. During the play of a cricket match, two members of the batting team are on the field, although their team-mates wait off the field. Those two players are the existing batsmen. Each batsman stands near one of the two wickets also end of the cricket pitch near the centre of the ground.

The two batsmen have different roles:

The striker stands in front of the wicket nearest him and attempts to protect it from balls bowled by the opposing bowler from the other wicket. The non-striker stands stopped near the bowler's wicket. While protecting his wicket, the striker may also hit the ball into the field and attempt to run to the opposite wicket, exchanging places with the non-striker. This score a run, the two batsmen may continue to exchange places, scoring additional runs, until members of the fielding team gather and return the ball to either wicket.

Membrane Filtration

A well-arranged process conduction which infact work without the addition of chemicals. Membrane technology is a generic term for separation processes. With membrane filters, filtration mainly occurs on the filter surface. Particles, which are larger than the normal pore size, remain on the filter, smaller particles pass through it unless other interactions get retained in them.

They are used to separate colloids, Suspended particles and molecules from liquids. Thus feed flow is divided into two streams a filtrate stream, and a highly concentrate stream.
Membrane systems with its filtration can be managed in either dead-end flow or cross-flow. The purpose of the optimization of the membrane techniques is the achievement, which is of the highest possible production for a long period of time, with acceptable pollution levels.

Polymer

Polymer is a substance collected of molecules with large molecular mass collected of repeating structural units, or monomers, connected by covalent chemical bonds. The word is resulting from the Greek, πολυ, polu, "many"; and μέρος, meros, "part". Well known examples of polymers contain plastics, DNA and proteins.

While the term polymer in popular usage suggests "plastic", polymers consist of a large class of natural and synthetic materials with a variety of properties and purposes. Natural polymer materials such as shellac and amber have been in utilize for centuries. Biopolymers such as proteins (for example hair, skin and division of the bone structure) and nucleic acids take part in crucial roles in biological processes. A variety of other natural polymers survive, such as cellulose, which is the major constituent of wood and paper.

Space Shuttle Solid Rocket Booster

The Space Shuttle Solid Rocket Booster is the rocket that provides 83% of liftoff thrust for the Space Shuttle. It is the largest and most powerful solid rocket ever flown, and the most powerful rocket motor of any type ever flown. Each SRB produces 1.8 times the liftoff thrust of the F-1 engine used in the Saturn V moon rocket.

The two reusable SRBs provide the main thrust to lift the Space Shuttle off the pad and up to an altitude of about 150,000 feet . In addition, the two SRBs carry the entire weight of the external tank and orbiter and transmit the weight load through their structure to the mobile launcher platform. Each booster has a liftoff thrust of approximately 2,800,000 lbf at launch. They are ignited after the three space shuttle main engines' thrust level is verified. The two SRBs provide 83 % of the thrust at lift-off. Seventy five seconds after SRB separation, SRB apogee occurs at an altitude of approximately 220,000 feet , after which they land on parachutes; impact occurs in the ocean approximately 122 nautical miles downrange, after which the two are recovered.

Capital market

The capital market is the market for securities, where companies and the government can heave long-term funds. It includes the stock market and the bond market. Financial regulators, such as the U.S. Securities and Exchange Commission, oversee the capital markets in their selected countries to make certain that investors are protected against fraud. The capital markets consist of the primary market, where new issues are spread to investors, and the secondary market, where existing securities are traded.

Art of Loving

According to Erich From, love is the most excellent reaction to the problem of human being. Love is the most satisfying accomplishment of humanity’s most powerful objective the desire of interpersonal union. Having a capability of grave thinking and self-awareness, humans realize their aloneness and separateness, their individuality and their short life span. The aspiration for interpersonal combination is the most powerful motivated in man. It is the most basic excitement; it is the force which keeps the human race together family, clan, society, nation, and world. As mentioned above, love, turns out to be the most fulfilling of all approach to go beyond limits of individual life. All forms of orgiastic unions are controlling and even violent; they are temporary and periodical. It is a union in which the individual self disappears to a large amount and where the aim is to belong to the group. There is orgiastic condition, which may have the form of sexual orgasm, alcohol, drugs and etc. Regrettably, equality today means similarity, rather that oneness. Orgiastic unions result in a rising sense of separateness. People try to be equal by performing tasks and feelings agreed by the system and trying to follow the similar rules, the same model of life from the age three or four. Union by consistency is calm and it is permanent.

A Civil Role Model

The word civil carries a lot of power. The usage needs to be carefully considered when it's entered into a sentence or an expression. Civil means a wide difference of things. It can be defined as a way to be attentive of the forms required for good reproduction. It can also be a means to the needs and affairs of the common public. However, the latter of the two definitions can also be extended to include a definition of the private rights and the remedy sought by action or costume. The point is that the word civil has a greater significance that has been embraced by our American legal traditions. It is the premise that law is there to provide the people and the lawyers are nothing more than mere guardians of law.
These are thoughts that were measured during the class viewing of A Civil Action. In the events of the case, there were many concerns that were brought up about our permissible culture.

Urban-suburban

Urban-suburban bus line is usually categorized as public transit, particularly for large metropolitan transit networks. Usually these routes cover a moderately long distance compared to most transit bus routes, but still short — frequently 40 miles in one direction. An urban-suburban bus line normally connects a suburban area to the downtown core.
The bus can be amazing as easy as a mere refitted school bus (which sometimes already have overhead storage racks), or a standard transit bus customized to have some of the functionality of an interstate coach. The example shown here has the same extent as a standard transit bus, but with one door and air conditioning. It provides accommodations for the disabled (through a lift at the front), and thus have a few high-back seats, usually in the front, that can be folded up for wheelchairs. The rest of the seats are recline upholstered seats and have person lights and overhead storage bins. Because it is a traveler bus, it has some (but not much) standing rooms, stop-request devices, and a farebox. This model also has a bike rack at the front to house two bicycles. Some lines use a full-size throughway coach with on board toilet, such as the "TrainBus" service of West Coast Express.

Waka

In the Maori language, waka are Maori watercraft, usually canoes. Similar craft are encounter in Polynesia, with connected names such as vaka. Waka range is from small, lightweight canoes, such as waka tiwai used for fishing individuals, during very large waka taua, manned by up to eighty paddlers and up to fourty mtrs in length, large double-hulled canoes for oceanic voyaging.

Many waka are single-hulled vessels locate from hollowed tree trunks. Small waka consist of an only piece as large waka typically consist of some pieces jointed and lashed together. Some waka, mainly in the Chatham Islands, were not usual canoes but were constructed from raupo stalks. Ocean waka, Paddled could be in any size, but were usually propelled by sail. Waka taua are paddled to put across their mana.Small efficient waka are commonly plain and simple. Superior canoes waka taua in testing are extremely carved. Waka taua are no longer used in fighting but frequently for official purposes.

A long lasting comedy

In the world everyone expose toward comedy. We see comedy in a different ways. These ways include: cinema, acting, situational comedies on small screen, and stand up comedians. However, there is something very different about the classic comedy today compared to the play the significance of person Earnest written by Oscar Wilde. The modern comedy generally uses characters that are humorous or actors that are known to be great comedians. What I mean by this is the characters are not generally serious or doing something of the serious personality. In The Importance of Being Earnest Oscar Wilde uses impossibility, joke, and paralleled irony to make characters that are in a serious type surroundings become comic.
Most commonly, when we think of impossibility, we think of a statement that is conflicting or far fetched but someway is true and it also different.

Computer printer

A computer printer, or more usually just a printer, is a device that produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as computer peripherals, and are permanently attached by a printer cable to a computer which serves as a text source. Other printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network.
In addition, many modern printers can directly border to electronic media such as memory sticks or memory cards, or to image capture devices such as digital cameras, scanners; some printers are combined with a scanners and/or fax machines in a single unit.

A Need for Welfare

There is an old joke that asked where you find a welfare recipient’s check under his work boots of course. For a long time now, since the expert formation of a stable government, the U.S government has had the programs and passed laws that either dealt with issues of or influenced family. Many of these family programs and laws currently in place today are often and usually debated. One of the most debated and most labored over family programs or laws are welfare.
This is because there is now a smallest amount of income so the poor no longer have the need to go out and commit crimes to attain such money.

Estate law

Estates may also be held jointly as joint tenants with rights of survivorship or as tenants in common. The difference in these two types of joint ownership of an estate in land is basically the inheritability of the estate. In joint tenancy (or in marriage this is sometimes called tenancy of the entirety) the surviving tenant (or tenants) become the sole owner (or owners) of the estate. Nothing passes to the heirs of the deceased tenant. In some jurisdictions the magic words "with right of survivorship" must be used or the tenancy will assumed to be tenants in common. Tenants in common will have a heritable portion of the estate in proportion to their ownership interest which is presumed to be equal amongst tenants unless otherwise stated in the transfer deed.

There are other types of estates in land that are used to prevent the alienation of land (also used in the law of trusts). Generally these are called future interests, an example being the rule against perpetuities. See also the Rule in Shelley's Case. Real property may not only be owned it may be leased in which the possession of the property is given to the tenant for a limited period of time. Such leases are also called estates such as an estate for years, a periodic tenancy or an estate at will. Real property may also be owned jointly through the device of the condominium or cooperative

Microscope slide

A microscope slide was initially a 'slider' made of ivory or bone, containing specimens held between disks of apparent mica. These were popular in Victorian England until the Royal Microscopically Society introduced the uniform microscope slide in the form of a thin sheet of glass used to hold objects for examination under a microscope. A standard microscope slide is 75 x 25 mm and about 1.0 mm thick. A range of other sizes is obtainable for various special purposes.

Currency

A currency is a component of exchange, facilitating the transfer of supplies and services. It is a form of money, where money is a capable medium of exchange, and it is also considered by a number of people as a store of value, created through a claim to its central bank assets. A currency zone is a country in which a specific currency is the main medium of exchange. To facilitate trade between currency zones, there are exchange price at which currencies can be exchanged beside each other. Currencies can be classified as also floating currencies or fixed currencies based on their exchange rate regime.

In general usage, currency at times refers to only paper money, as in "coins and currency", but this is confusing. Coins and paper money are both forms of currency. In most cases, each country has control over the supply and manufacture of its own currency.

Auditory clocks

For expediency, distance, telephony or blindness, auditory clocks here the time as sounds. The sound is either spoken normal language, or as auditory codes (e.g. numbers of sequential bell rings on the hour represent the number of the hour like the clock Big Ben). Most telecommunication companies also supply a Speaking clock service as well.

Donkey jacket


A Donkey jacket is a tiny buttoned coat, normally made of unlined black or dark blue woollen stuff; originally worn as a work jacket in the United Kingdom.
When used as a work jacket, it occasionally bears the name of the company which supplies the jacket, or the name of the company for which the wearer works. The jacket usually has two large hip pockets, and at times an inside poacher's pocket.The donkey jacket is regarded as characteristic of the British manual worker.

Planetary ring

A planetary ring is a ring of dirt and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but the other three gas giants of the solar system possess ring systems of their own.

Ear buds/Earphones


Ear buds or earphones are headphones of a smaller size that are positioned directly outside of the ear canal, but without fully enveloping it. They are generally inexpensive and are favored for their portability and convenience. However, due to their inability to provide isolation, they are not capable of delivering the same dynamic range offered by many full-sized headphones and canal phones for a given volume level. As a result, they Are often used at higher volumes in order to drown out noise from the users surroundings, which increases the risk of hearing-loss.

Transistor radio


The transistor radio is a small radio receiver. RCA established a prototype transistor radio in 1952. The first profitable transistor radio, the Regency TR-1, was announced on October 18, 1954 by the Regency Division of Industrial Development Engineering Associates of Indianapolis, Indiana and put on sale in November of 1954. It cost $49.95 (the equivalent of $361 in year-2005 dollars) and sold approximately 100,000 units.

Grape

A grape is the non-climacteric fruit that grows on the perennial and deciduous woody vines of the folks Vitaceae. Grapes grow up in clusters of 6 to 300, and can be black, blue, golden, green, purple, red, pink, brown, peach or white. They can be eaten raw or used for producing jam, grape juice, and jelly, wine and grape seed oil. Cultivation of grapevines occurs in vineyards, and is called viticulture. One who studies and practices growing grapes for wine is called a viticulturist. The leaves of the grape vine itself are considered safe to eat and are used in the production of dolmades.

Web portal

A Web portal is a site that functions as a point of admittance to information on the World Wide Web. Portals present information from diverse sources in a united way. Popular portals are MSN, Yahoo, and AOL. Aside from the search engine standard, web portals offer other services such as news, stock prices, infotainment and various other features. Portals provide a way for enterprises to provide a steady look and feel with access control and procedures for multiple applications, which otherwise would have been different entities altogether.

Grafting


Grafting is a method of plant propagation extensively used in horticulture, where the tissues of one plant are encouraged to fuse with those of another. It is most usually used for the propagation of trees and shrubs grown commercially. In most cases, one plant is chosen for its roots, and this is called the stock or rootstock. The other plant is chosen for its stems, leaves, flowers, or fruits and is called the scion.In stem grafting, a common grafting method, a shoot of a chosen, desired plant cultivar is grafted onto the stock of another type. In another common form called budding, a dormant side bud is grafted on the stem of another stock plant, and when it has fused successfully, it is encouraged to grow by cutting out the stem above the new bud.For successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be located in contact with each other. Both tissues must be kept alive till the graft has taken, typically a period of a few weeks. Successful grafting only requires that a vascular connection takes place between the two tissues. A physical weak point often still occurs at the graft, because the structural tissue of the two distinct plants, such as wood may not fuse.

Applied Micro Circuits Corporation

Applied Micro Circuits Corporation is a fables semiconductor company scheming network and embedded Power Architecture, optical transport and storage solutions. They bought assets, IP and engineers concerning the PowerPC 400 microprocessors from IBM in 2004 for $227 million and they now market the processors under their own name. The deal also included access to IBM's SoC design methodology and advanced CMOS process technology.

3ware is a producer of RAID controllers and storage products. Founded as an self-governing company in 1997, it was acquired by AMCC in April 2004.This division has usually been focused on SATA and PATA RAID devices. They were one of the pioneers in implementing "multi-lane" cabling for RAID systems which greatly reduced cable difficulty in systems with many hard drives.

Watercraft

A watercraft is a vehicle, vessel or craft designed to move across water for pleasure, recreation, physical exercise, commerce, transport of people and goods, and military missions. It is resulting from the term "craft" which was used as term to describe all types of water going vessels. Most watercraft would be described as either a ship or a boat. However, there are a number of craft which many people would consider neither a ship nor a boat, such as: canoes, kayaks, rafts, barges, catamarans, hydrofoils, windsurfers, surfboards (when used as a paddle board), underwater robots, torpedos and jet skis.

Exploration

Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown regions, including space, for oil, gas, coal, ores, caves, water (Mineral exploration or prospecting), or information.The term can also be used to describe the first incursions of peoples from one culture into the geographical and cultural environment of others. Although exploration has existed as long as human beings, its peak is seen as being during the Age of Discovery when European navigators travelled around the world discovering new worlds and cultures.In scientific research, exploration is one of three purposes of research.Exploration is the attempt to develop an initial, rough understanding of some phenomenon.

Star

A star is an enormous, luminous ball of plasma. Stars cluster together to form galaxies, and they dominate the visible universe. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth, together with daylight. Other stars are visible in the night sky, when they are not outshone by the Sun. A star shines because nuclear fusion in its core releases energy which traverses the stars internal and then radiates into outer space. Almost all elements heavier than hydrogen and helium were produced inside the cores of stars.

Astronomers can establish the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its development and eventual fate. Other individuality of a star that is determined by its evolutionary history includes the diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertz sprung-Russell diagram (H-R diagram), allows the current age and evolutionary state of a particular star to be determined.

Shrimp fishery


A shrimp fishery is a fishery directed toward harvesting either shrimp or prawns. Fisheries do not usually differentiate between the two taxa, and the terms are used interchangeably. This article therefore refers to the catching of either shrimp or prawns.
A number of the larger species, including the Atlantic white shrimp (Penaeus setiferus), are caught commercially and used for food. Recipes utilizing shrimp form part of the cuisine of many cultures: examples include jambalaya, okonomiyaki, poon choi, bagoong, Kerala and scampi.Preparing shrimp for consumption usually involves removing the shell, tail, and "sand vein". As with other seafood, shrimp is high in calcium, protein and low in food energy.Shrimp and prawns are versatile ingredients, and are often used as an accompaniment to fried rice. Common methods of preparation comprise baking, boiling and frying. As stated in the movie Forrest Gump

History of bullets

The history of bullets parallels the history of firearms. Advances in one either resulted from or precipitated advances in the additional. Originally, bullets are round metallic or stone balls placed in front of a volatile charge of gunpowder at the end of a closed tube. As firearms became more scientifically advanced, from 1500 to 1800, bullets changed very little. They remained simple round lead balls, called rounds, conflicting only in their diameter. The growth of the hand culverin and matchlock harquebus brought about the use of cast lead balls as projectiles. "Bullet" is derived from the French word "boulette" which approximately means "little ball". The original musket bullet was a globular lead ball two sizes smaller than the bore, wrapped in a loosely-fitted paper patch which served to hold the bullet in the barrel firmly upon the powder. The loading of muskets was, therefore, easy with the old smooth-bore Brown Bess and similar military muskets.

Description of Quick Ring

The basic Quick Ring system consisted of seven serial links, six of them carrying data, and one a 50 MHz clock signal. Two physical media were specified, sets of twisted-pair copper wiring embedded in a thin plastic strip for use inside a computer, or the same signals using frequency-division multiplexing in a single fiber optic cable for longer links between machines.

The data lines were clocked at seven times the clock signal, so each clock "tick" moved 42 bits of data over the bus for a raw data rate of 2.1 Gbit/s. Ten bits of the 42 were used for signaling and control, leaving the other 32 for data, resulting in a net data transfer rate of 1.6 Gbit/s, or 200 MBytes/s.

Each Quick Ring interface enclosed two of these 200 MB/s links, one for "upstream" and one for "downstream" connections in a point-to-point ring. Since the system was not a bus, machines could talk up and downstream at the same time without interfering with other users. The drawback was that each hop over an intervening point added a latency of up to 1.3 µs.

Since Quick Ring was built in a ring topology there was no need for a dedicated switch, or router, making the system lower cost. It used a circuit switching system, in which the message path is set up before the data is sent, and once set up the connection is very lightweight. This is as opposed to packet switching, in which every message contains all of the data needed to reach the destination, this is more flexible, but adds overhead. Of the 10 bits of control data, four were used to specify a circuit number, allowing for a total of 16 devices per ring.

Protein


Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by a gene and encoded in the genetic code. Although this genetic code specifies 20 "standard" amino acids, the residues in a protein are often chemically altered in post-translational modification: either before the protein can function in the cell, or as part of control mechanisms. Proteins can also work together to achieve a particular function, and they often associate to form stable complexes.

Like other biological macromolecules such as polysaccharides and nucleic acids, proteins are essential parts of all living organisms and participate in every process within cells. Many proteins are enzymes that catalyze biochemical reactions, and are vital to metabolism. Other proteins have structural or mechanical functions, such as the proteins in the cytoskeleton, which forms a system of scaffolding that maintains cell shape. Proteins are also important in cell signaling, immune responses, cell adhesion, and the cell cycle. Protein is also a necessary component in our diet, since animals cannot synthesise all the amino acids and must obtain essential amino acids from food. Through the process of digestion, animals break down ingested protein into free amino acids that can be used for protein synthesis.

Shoe

A shoe is a thing of footwear worn on the foot or feet of a human, dog, cat, horse, or doll. Shoes may vary from a simple flip-flop to a multifaceted boot. Shoes may have high or low heels, although in western cultures, high heels are considered a woman's style. Shoe materials include leather or image. Athletic shoe soles may be made of rubber.
Dress and casual shoes
Casual shoes, made of leather Dress shoes are categorized by smooth and supple leather uppers, leather soles, and narrow sleek shape. Casual shoes are characterized by sturdy leather uppers, non-leather outsoles, and wide profile. Some designs of dress shoes can be worn by either gender. The majority of dress shoes have an upper covering, commonly made of leather, enclosing most of the lower foot, but not covering the ankles. This upper part of the shoe is often made without apertures or openings, but may also be made with openings or even itself consist of a series of straps, e.g. an open toe featured in women's shoes. Shoes with uppers made high to cover the ankles are also available; a shoe with the upper rising above the ankle is usually considered a boot but certain styles may be referred to as high-topped shoes or high-tops. Usually, a high-topped shoe is secured by laces or zippers; although some styles have elastic inserts to ease slipping the shoe on.

Tourism


Tourism is travel for predominantly leisure or relaxation purposes, and also refers to the prerequisite of services in support of this act. Tourists are people who ,travel to and stay in places outside their common environment for not more than one consecutive year for leisure, business and other purposes not related to work out of an activity remunerated from within the place visited.

Tourism has become an enormously popular, global activity. As a service industry, tourism has frequent tangible and intangible elements. Major tangible elements include transportation, accommodation, and other apparatus of a hospitality industry. Major intangible elements relate to the purpose or inspiration for becoming a tourist, such as rest, relaxation, the opportunity to meet new people and experience other cultures, or simply to do something different and have an adventure.

Tourism is crucial for many countries, due to the income generated by the expenditure of goods and services by tourists, the taxes levied on businesses in the tourism industry, and the prospect for employment and economic advancement by working in the industry.

Artificial intelligence (Collective and non-human intelligence)


Some thinkers have explored the idea of combined intelligence, arising from the harmonization of many people. A battleship, for instance, cannot be operated by a single person's knowledge, actions and intelligence; it takes a equivalent and interacting crew. Similarly, the interesting behaviors of a bee colony are not exhibited in the aptitude and actions of any single bee, but rather manifest in the performance of the hive. These ideas are explored as a basis for human thought, with applications for artificial intelligence, by MIT AI pioneers Norbert Wiener and Marvin Musky. Artificial intelligence has emerged from Computer science as a area of expertise which seeks to make computers act in gradually more intelligent ways, and provides insights into human thought processes.

When bearing in mind animal intelligence, a more general definition of intelligence might be applied: the "ability to adapt efficiently to the environment, either by making a change in oneself or by changing the surroundings or finding a new one". Many people have also speculated about the possibility of outer space intelligence.

Multitrack recording

Multitrack recording is a method of sound recording that allows for the recording of multiple sound sources, whether at the same time or at different times. This is probably the most common technique of recording popular music: Musicians or singers can be recorded independently, then these performances can be edited together to create a cohesive result. It is also called 'multitracking' or just 'tracking' for short.Multitrack recording devices are available with varying capacities. When recording a segment of audio, which is also known as a track, audio engineers and musicians may select which track or tracks on the device will be used.

Willamette River

100 The Willamette River is a tributary of the Columbia River, approximately 240 mi long, in northwestern Oregon in the United States. Flowing northward between the Coastal Range and Cascade Range, the river and its tributaries form a basin called the Willamette Valley containing the largest inhabitants centers of Oregon, including Portland, which sits along both sides of the river near its mouth on the Columbia. Its lush valley is fed by prolific precipitation on the western side of the Cascades, forming one of the most productive agricultural regions of North America that was the destination for many if not most of the emigrants along the Oregon Trail. The river was an important transportation route throughout much of the early history of the state, furnishing a means of conveying the vast timber and agricultural resources of the state to the outside world.

Description

The Willamette rises in three separate forks in the mountains south and southeast of Eugene, at the southern end of the Willamette Valley. The Middle Fork and North Fork raise on the western side of the Cascades between Three Sisters south to Diamond Peak, with the Middle Fork in receipt of the North Fork northwest of Oakridge and flowing northwest from side to side the mountains to the southern end of the Willamette Valley. The Coast Fork rises in the lower mountains south of Cottage Grove, flowing north to join the Middle Fork 2 mi southeast of Eugene.

From Eugene, the joint river flows NNW across the plain of the southern Willamette Valley to Corvallis, and then follows a zigzag course past Albany and around the isolated hills in the central valley, passing west of downtown Salem. From Salem it flows north in a roundabout course across the northwest plain of the valley, reaching the hills at Newberg, where it turns sharply ENE along the hills, passing through an opening in the hills at Oregon City, the position of the Falls of the Willamette and the head of navigation. From Oregon City it flows northwest, past Lake Oswego and Milwaukie on the south edge of Portland, then passing between east and west Portland, where it is spanned by a series of urban bridges. Downstream of downtown Portland it flows northwest through the industrial port area of Portland Harbor, then splitting into two channels around Sauvie Island, both of which hook around to enter the Columbia from the west, with the main channel entering on the north edge of Portland and the smaller Multnomah Channel entering just about 15 mi NNW at St.Helens.

Traffic light

A traffic light or traffic signal is a signaling machine positioned at a road meeting point or walker crossing to indicate when it is secure to drive, ride or walk, using a worldwide color code.

History

In the 1920s, after continued obliteration of a normal traffic light in its Tipperary Hill Irish neighborhood, the City of Syracuse in the United States gave up and installed a traffic light with green on the top. The Irish had objected to the fact that "British" red was placed above "Irish" green.On 10 December 1868, the first traffic lights were installed outside the Houses of Parliament in London. They resembled railway signals of the time, with semaphore arms and red and green gas lamps for night use.

The modern electric traffic light is an American formation. As early as 1912, Salt Lake City policeman Lester Wire set up the first red-green electric traffic lights. On 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of 105th Street and Euclid Avenue in Cleveland, Ohio. Based on the design of James Hoge, it had two colors, red and green, and a signal to give a warning for color changes. The first three-color traffic lights were introduced in New York and Detroit in 1920.

The first interrelated traffic signal system could be seen in Salt Lake City, Utah in 1917, with six linked intersections restricted at the same time from a manual switch. Automatic control of interrelated traffic lights was introduced March 1922 in Houston, Texas

The first automatic tentative traffic lights in England were deployed in Wolverhampton in 1927.

Garrett Morgan is sometimes incorrectly credited as the inventor of the traffic light. See

Ampelmännchen traffic lights have come to be seen as a nostalgic sign for the former German Democratic Republic.

Beaver Coins

100 Beaver Coins, also known in Pioneer days as Beaver Money, were gold coins for a short time minted by the Provisional Government of the Oregon Territory in the not on time 1840's. The coins were obtainable in $5 and $10 dollar denominations. Their name comes from the important Beaver depicted on the face of the coins. Today these coins are quite rare and precious.

The influx of settlers into the Oregon Country produced a deficiency of circulating currency. The inhabitants at the time resorted to using gold specks or minting their own gold coins for use in trading. Many settlers began lobbying the territory's new government to correct this condition.

The Provisional Territorial Legislature at Champoeg then gave the appreciation for the Oregon Exchange Company to mint currency. Although the Oregon Exchange Company was more often than not a personal organization, the territorial government set the coin's values, authorized a mint, and chosen the officers to the mint. The mint was situated in Oregon City, Oregon.

After Oregon's administrator U.S. territory rank, the Oregon Exchange Company became an completely personal enterprise ongoing its operations until Governor Joseph Lane ruled the operation illegal.

Clock

A clock is an instrument for measuring time.Those used for technical purposes, of extremely high accuracy, are sometimes called chronometers. A portable clock is called a watch. The clock in its most common modern form displays the hours, minutes, and sometimes seconds that pass over a twelve or twenty-four-hour period.
The world's first self-striking clock was said to be invented by Chang Yeong-Sil, a chief enginner of Korea, in Korea during the Joseon Dynasty. It was called Chagyongru, which means "self-striking clock" in Korean
The development of electronics in the twentieth century led to clocks with no clockwork parts at all. Time in these cases is measured in several ways, such as by the behaviour of quartz crystals, or the decay of radioactive elements. Even mechanical clocks contain since come to be largely powered by batteries, removing the need for winding.

Peach

The peach (Prunus persica) is a tree that bears a juicy fruit of the same name. It has a single large seed enclosed in hard wood (called the "pit" or "stone"), yellow or whitish flesh, a delicate aroma, and a velvety skin. Peaches, along with cherries, plums and apricots, are stone fruits (drupes). Cultivated peaches are separated into freestone and clingstone varieties, depending on whether the flesh sticks to the pit; both kinds can be any color. Peaches with white flesh characteristically are very sweet with little acid flavor, while yellow-fleshed peaches classically have an acidic tang coupled with sweetness. Both colors often have some red on their skin. Low-acid white-fleshed peaches are the most popular kinds in China, Japan, and neighboring Asian countries, while Europeans and North Americans have historically favored the acidic, yellow-fleshed kinds.

Kashmir

Kashmir is known as heaven on the earth. In the seventeenth century the Mughal emperor Jahangir set his eyes on the valley of Kashmir. He said that if paradise is anywhere on the earth, it is here, while living in a house boat on the mesmerizing Dal Lake. The pleasure of the Mughal gardens makes every minute one spends in Kashmir a joy to the soul. In Jammu and Kashmir the most significant tourist places are Kashmir, Srinagar, Mughal gardens, Gulmarg, Pahalgam-the valley of shepherds, Jammu, Ladakh.
Because of the quite tolerable climate on the higher planes of Jammu and Kashmir, and also because of its scenic beauty and bodies of water, Jammu and Kashmir are a tourist attraction. Until a few decades ago, "Going to Kashmir" was synonymous in India with going on a honeymoon, or for a tour to a cold place during hot summers.
Some areas need a special permit for non-indians to visit.

Rameswaram

Rameswaram (Chennai to Rameswaram 572 km) is a small island in the Gulf of Mannar, is a major pilgrim centre. It is linked to the mainland by road and railway bridges. Rameswaram is a holy place because Sri Rama, on his return from Sri Lanka, offered his thanks to Lord Shiva and performed pooja to wash away his sin in killing the Demon King, Ravana.
Rameswaram is known for its 22 theerthas or wells in and around the main temple. This place is evenly sacred to both Vaishnavites and Shaivites. According to Hindu Mythology, if one visits Rameswaram and prays to Lord Shiva one will be relieved of one’s sins. It is 197 metres long.
The Ramanathaswamy temple is famous for its magnificent corridors and massive sculptured pillars. The third corridor of Ramanathaswamy temple is the longest one in the world.
Besides pilgrimage, Rameswaram Island has some places, which are ideal picnic spots. There are beautiful beaches at Olaikuda, Dhanushkodi and Pamban. The Olaikuda beach is 1 km from the main temple and s engulfed by coral reefs, which makes bathing in the sea safe and enjoyable. With diving glasses and respiration tubes, scuba diving is safe and possible. Flamingos, sea gulls and a variety of birds travel to the Rameswaram Island during winter.
Rameswaram is a main fishing centre of Tamil Nadu. Variety of fishes with export quality fish like prawns, sea cucumber, and lobster are available here. Rameswaram is also famous for its dry fish.

Sit flying

Sit flying is a form of locomotion obtainable to skydivers and vertical wind tunnel flyers. It describes the ability to 'fly' ones body in any direction while in a 'sit' position. It's called a 'sit' because it looks like the flyer is sitting in a chair.
The correct position for flying a sit is to orient yourself feet first in the direction of the relative wind and maintain 90-degree angle bends at the knees, hips, and shoulders. Wind from the tunnel or from free-fall should be hitting the flyer on the feet, hamstrings, bottom, and the underside of the arms. To move about relative to the tunnel or other jumpers, the flyer simply redirects the airflow the opposite direction the jumper wants to go. Newtonian mechanics then push the flyer in the preferred direction. Fall rate changes (descending faster or slower) can also be made. This is done by presenting more surface area (wide legs and arms, higher drag, slower fall rate) or less surface area (arms up or even stand up, less drag, faster fall rate) from the flyers body to the wind.

Traditional animation

This animation called cel animation, the frames of a traditionally animated movie are hand-drawn. The drawings are traced or copied onto transparent acetate sheets called cels, which are then located over a painted background and photographed one by one on a rostrum camera. Nowadays, the use of cels (and cameras) is mostly obsolete, since the drawings are scanned into computers, and digitally transferred directly to 35 mm film. The "look" of traditional cel animation is still preserved, and the character animator's work has remained essentially the same over the past 70 years. Because of the digital influence over modern cel
animation, it is also known as tradigital animation.
Examples: The Lion King, Spirited Away, Les Triplettes de Belleville
Full animation
The most common style in animation, known for its realistic and often very detailed art.
Examples: All Disney feature length animated films, The Secret of NIMH, The Iron Giant
Limited animation
A cheaper process of creating animated cartoons that does not follow a "realistic" approach.
Examples: The Flintstones, Yellow Submarine Rubber hose
The characters are usually cartoony, and the animators have a lot of artistic freedom as rubber hose animations don't have to follow the laws of physics and anatomy in the same degree as the other main styles in animation.
Examples: Early Mickey Mouse cartoons, Ren and Stimpy, Popeye
Rotoscoping
A technique where animators trace live action movement, frame by frame, for use in animated films.
Examples: Gulliver's Travels, American Pop
