Plastic is a term that covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, ...

Other plastics emerged in the prewar period, though some would not come into widespread use until after the war. By 1936, American, British, and German companies were producing polymethyl methacrylate (PMMA), better known as "acrylic". Although acrylics are now well known for their use in paints and synthetic fibers, such as "fake furs", in their bulk form they are actually very hard and more transparent than glass, and are sold as glass replacements under trade names such as "Plexiglas" and "Lucite". Plexiglas was used to build aircraft canopies durin ...

Brain plasticity refers to the changes that occur in the organisation of the brain, and in particular changes that occur to the location of specific information processing functions, as a result of the effect of experience. The term cortical plasticity is more commonly used, however there is no particular restriction of the phenomenon to the cortex. A common and surprising consequence of plasticity is that the location of a given funct ...

Plastic surgery is a general term for operative manual and instrumental treatment which is performed for functional or aesthetic reasons. The word "plastic" derives from the Greek plastikos meaning to mould or to shape; its use here is not connected with modern plastics. The principal areas of plastic surgery include two broad fields. Reconstructive surgery, including microsurgery, focuses on undoing or masking the destructive effects of trauma, surgery or disease. Reconstructive surgery may include closing ...

A bottle is a small container with a neck that is narrower than the body and a "mouth." Bottles are often made of glass, plastic or aluminum, and typically used to store liquids. e.g. water, milk, soft drinks, beer, wine, oil for cooking and as fuel, medicine, liquid soap, shampoo, ink, etc. For some bottles a deposit is paid, which is returned after returning the bottle to the retailer. For other glass bottles there is often separate garbage collection for recycling. A device used to close ...

A bag is a container that is usually used for storing or holding something. Bags are non-rigid, normally made of paper, cloth, thin plastic or some other flexible material. A bag may have one or two handles, or neither of these. A bag may be closable by a zipper, etc., or simply by folding (e.g. in the case of a paper bag). Sometimes a money bag or travel bag has a lock. Sachets are fabric bags that are filled with potpourri and tied off with ribbons. Bags vary from small ones, like purses (e.g. as an alternative to putting personal things in pockets of clothing) to large ...

Whipping is the tying of several turns of twine around the end of a rope to prevent it from unravelling. It is not to be confused with splicing, which is a method of joining two ropes together, or joining one rope to itself, usually to form an eye or loop. Whipped rope - Whipping natural fiber rope. Whipping usually starts inside and works towards the end of the rope. The twine is first laid along the rope end in the form of an elongated double S that lies along the valley between one strand ...

In engineering, buckling is a failure mode of a structural member characterised by a failure to react to the bending moment generated by a compressive load. Buckling - Buckling in columns. The ratio of the length of a column to the least radius of gyration of its cross section is called the slenderness ratio (usually expressed with the Greek letter lambda - λ). This ratio affords a means of classifying columns. All the following are approximate values used for convenience. A short steel ...

Cold Work is a quality imparted on a material as a result of plastic deformation at low to moderate temperatures (typically <0.5 Tm). Such deformation increases the concentration of dislocations which may subsequently form low-angle grain boundaries surrounding sub-grains. Cold work generally results in a higher yield strength as a result of the increased number of dislocations and the Hall-Petch effect of the sub-grains. However, there is a simultaneous decrease in the ductility. The effects of cold working may be removed by annealing the material at high temperatures where recovery and r ...

Corn, or maize, has a number of uses. Besides being used for human and livestock consumption, corn can be used to produce ethanol, as a biomass fuel source, and in corn construction. According to the Michigan Department of Agriculture, "corn can be made into fuel, abrasives, solvents, charcoal, animal feed, bedding for animals, insulation, adhesives, and more. The kernel is used as oil, bran, starch, glutamates, animal feed, and solvents. The silk is combined with other parts of the corn plant to be used as part of anima ...

Plastic was launched in January 2001 under Automatic Media, the web-culture conglomerate that included suck.com. In following with Automatic's model of small, low-cost boutique websites, there were only 4 members of Plastic's initial staff. Plastic won a Webby award in its first six months. When Automatic Media folded in June of that year, several of the editors remained on, working pro bono. Despite heavy server problems and downtime in the months following Automatic's collapse, Carl Steadman, one of Suck's original founders, announced his intentions to buy Plastic, and moved the entire board onto new servers. Since then, Carl has se ...

When compared to glass or metallic materials, plastic poses some unique challenges from a recycling perspective. Chief among them is their low entropy of mixing, which is due to the high molecular weight of large polymer chains. Another way of stating this problem is that, since a macromolecule interacts with its environment along its entire length, its enthalpy of mixing is very, very large compared to that of a small organic molecule with a similar structure; thermal excitations are not often enough to drive such a huge molecule into solut ...

Plastic's moderation system is very similar to the one seen on Slashdot. Plastic members are randomly awarded moderation points which can be given out as they see fit. In any discussion thread, a person with moderation points can mod a post up or down, based upon the content, with a descriptive tag, such as 'compelling', 'scholarly', 'astute', 'disingenuous', 'obnoxious', etc. It costs one point to mod a post up, and two to mod a post down. A given comment can have a score between -1 and 5 inclusive at half point intervals, and Plastic users ...

Plastic bullet - Development. The bullet was developed by the British as the plastic baton round (PBR). It was intended to replace the older rubber bullet with a projectile that could be fired directly at targets while also reducing the risk of serious injury or death. It was introduced in 1972 and initially was used alongside the rubber bullet, which it replaced completely in 1975. < ...

In the late 1950's, the flawless American lawn was beginning to take over, and with it the bright colored pink flamingo. Pink was a big color, plastic was still news. The 1960s were not as friendly to the pink flamingo. There was a rebellion against everything man made. It was a time to go back to nature, and the plastic flamingo quickly became the prototype of bad taste and anti-nature. By 1970 ...

The history of the pink flamingo can be traced back to 1946 when a company in Leominster, Massachusetts called Union Products started manufacturing products they titled “Plastics for the Lawn”. Their original collection included two dimensional dogs, ducks, frogs, and even a flamingo. In 1956, the company hired a young designer named Don Featherstone. Don's first project was to redesign their popular duck into the third dimension. Don used a live duck as his model and after fi ...
