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.
