Abstract art

Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses colour and form in a non-representational way.In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, that depicts real forms in a simplified or rather reduced way—keeping only an allusion of the original natural subject. Such paintings were often claimed to capture amazing of the depicted objects' immutable intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" avoid any possible ambiguity.

Nutrition is a science which studies the relationship between diet and states of health and disease. Dietitians are Health professionals who are particular in this area of expertise. They are also the only extremely trained health professionals able to provide safe, evidence-based and accurate dietary advice and interventions.

Between extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as scurvy, obesity or osteoporosis, as well as mental and behavioral problems. Moreover, excessive ingestion of elements that have no apparent role in health, (e.g. lead, mercury, PCBs, dioxins), may incur toxic and potentially lethal belongings, depending on the dose. The science of nutrition attempts to understand how and why exact dietary aspects influence health.

Organization in sociology

In sociology "organization" is tacit as planned, synchronized and decided action of human beings to construct or compile a common tangible or intangible product. This action is usually framed by official membership and form. Sociology distinguishes the term organization into planned formal and unplanned informal organizations. Sociology analyses organizations in the first line from an institutional viewpoint. In this sense, organization is a permanent agreement of elements. These elements and their actions are resolute by rules so that a certain task can be fulfilled through a system of coordinated the division of labour.

An organization is defined by the rudiments that are part of it, its communication, its independence and its rules of action compared to outside events. By coordinated and planned cooperation of the elements, the organization is able to solve tasks that lie beyond the abilities of the single elements. The price paid by the elements is the restriction of the degrees of freedom of the elements. Advantages of organizations are enhancement, addition, and extension. Disadvantages are inertness and loss of interaction.

RISC (reduced instruction set computer)

In the mid-1980s to early-1990s, a crop of new high-performance RISC microprocessors appeared, which were initially used in special purpose machines and UNIX workstations, but have since become almost universal in all roles except the Intel-standard desktop.

The first commercial design was released by MIPS Technologies, the 32-bit R2000. The R3000 made the design truly practical, and the R4000 introduced the world's first 64-bit design. Opposing projects would result in the IBM POWER and Sun SPARC systems, respectively. Soon every major vendor was releasing a RISC design, including the AT&T CRISP, AMD 29000, Intel i860 and Intel i960, Motorola 88000, DEC Alpha and the HP-PA.

Market forces have "weeded out" many of these designs, leaving the PowerPC as the main desktop RISC processor, with the SPARC being used in Sun designs only. MIPS continue to supply some SGI systems, but are first and foremost used as an embedded design, notably in Cisco routers. The rest of the original crop of designs have either disappeared, or are about to. Other companies have attacked niches in the market, notably ARM, originally intended for home computer use but since focused at the embedded processor market. Today RISC designs based on the MIPS, ARM or PowerPC core are the vast majority of computing devices.

Paint is any liquid, liquifiable, or mastic composition which after application to a substrate in a thin layer is transformed to an opaque solid film.
Paint is used to protect, decorate (such as adding color), or add functionality to an object or outside by covering it with a pigmented coating. An example of protection is to retard corrosion of metal. An example of decoration is to add festive trim to a room interior. An example of added functionality is to alter light reflection or heat radiation of a surface.
As a verb, painting is the application of paint. Someone who paints creatively is usually called a painter, while someone who paints commercially is often referred to as a painter and decorator, or house painter.
Paint can be applied to almost any kind of object. It is used, among many other uses, in the production of art, in industrial coating, as a driving aid, or as a barrier to prevent corrosion or water damage. Paint is a semifinished product, as the final product is the painted article itself.

Belt (clothing)

A belt is a flexible band, characteristically made of leather or heavy cloth, and worn around the waist.belt supports trousers or other articles of clothing, and it serves for style and decoration.Historically, a belt was also used by educators for spanking children, and by masters for spanking servants. This use has frequently declined in the Western world, as it is viewed as too barbaric and uncontrollable a form of corporal punishment.At one end of the belt is a belt buckle that is shaped onto the other end of the belt. The other end of the belt contains several holes, into which a prong (which is part of the buckle) is inserted into it for the purpose of securing the belt. Sometimes, there is a clamp system so that no holes are wanted. In Western civilizations, men usually insert the belt through the pant loops in a counter-clockwise manner, while women tend to insert the belt through the pant loops in a clockwise direction.Since belts must be drawn firmly around the waist in order to hold up the pants, they may be less comfortable than suspenders, which allow trousers to hang loosely about the body.

Speed limit

A speed limit is the highest speed allowed by law for vehicles on a road.

Design speed
Speed limits are only peripherally interrelated to the design speed of the road.
In the United States, the design speed is "a selected speed used to establish the various geometric design features of the roadway" according to the 2001 AASHTO Green Book, the highway design manual. It has been changed from previous versions which considered it the "highest safe speed that can be maintained over a specific section of highway when conditions are so positive that the design facial appearance of the highway governs."

The design speed has largely been discredited as a sole basis for establishing a speed limit. Current U.S. standards for design speed derive from outdated, less-capable automotive technology. Also, the design speed of a given roadway is the theoretical maximum safe speed of the roadway's worst feature .The design speed usually underestimates the highest safe speed for a roadway and is therefore considered only a very conservative "first guess" at a limit.

85th percentile rule
An automobile dashboard viewing the speedometer with primary markings in miles per hour.Since the 1950s, United States traffic engineers have been taught the 85th Percentile Rule. The idea is that the speed limit should be set to the speed below which 85% of vehicles are traveling. The 85th percentile closely corresponds to one normal deviation above the mean of a normal distribution.
Every state in the United States statutorily or administratively picks a particular speed for a speed limit cap, meaning that no speed limit in that state may be set higher than the cap. A practical effect of this cap is that nearly every rural roadway in the U.S. has a speed limit that is well below the 85th percentile speed.
