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.

Abiotic pollination

It occurs when pollination is mediated without the participation of other organisms. For illustration, anemophily is pollination by wind. This form of pollination is very common in grasses, most conifers, and a lot of deciduous trees. Hydrophily is pollination by water and occurs in aquatic plants which let go their seeds directly into the surrounding water. About 80% of all plant pollination is biotic, of the 20% of abiotically pollinated species, 98% is by wind and 2% by water.

Troposphere

From the Greek word "τρέπω" importance to turn or mix. The troposphere is the lowest layer of the atmosphere; it starts at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (60,000 ft) at the equator, with some distinction due to weather factors. The troposphere has a enormous deal of vertical mixing due to solar heating at the surface. This heating warms air masses, which makes them less intense so they rise. When an air mass raises the force upon it decreases so it expands, doing work against the contrasting pressure of the surrounding air. To do work is to use energy, so the temperature of the air mass decreases. As the temperature decreases, water vapor in the air mass may concentrate or solidify, releasing latent heat that further uplifts the air mass. This process determines the maximum rate of refuse of temperature with height, called the adiabatic lapse rate.

Sports car

A sports car is an automobile planned for performance driving. Most sports cars are rear-wheel drive, have two seats, two doors, and are designed for exact handling, speeding up, and aesthetics. A sports car's dominant considerations can be superior road handling, braking, maneuverability, low weight, and high power, rather than traveler space, comfort, and fuel economy.

Sports cars can be either comfortable or Spartan, but lashing mechanical performance is the key attraction. Drivers regard brand name and the following racing reputation and history (for example, Ferrari, Porsche, Lotus) as important indications of sporting quality, but brands such as Lamborghini, which do not competition or build racing cars, are also awfully regarded.

A car may be a sporting car without being a sports car. Performance modifications of regular, production cars, such as sport compacts, sports sedans, muscle cars, hot hatches and the like, normally are not sports cars, yet share traits general to sports cars. Frequently, performance cars of all configurations are grouped as Sports and GT cars, or, infrequently, as performance cars.

Vegetable

Vegetable is a cookery term which usually refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat random and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are in general considered vegetables. Mushrooms, though belong to the biological kingdom fungi, and are also commonly considered vegetables. In common, vegetables are consideration of as being savory, and not sweet, although there are many exceptions. Nuts, grains, herbs, spices and culinary fruits are usually not exact vegetables.

Flight jacket

The flight jacket or bomber jacket is an item of clothing originally created for pilots, which ultimately became part of popular culture and clothing. In the First World War most airplanes did not have an enclosed cockpit, which necessitated an item of clothing that could keep pilots adequately warm. The classic sheepskin designed and manufactured firstly by Leslie Irvin and set up a manufacturing company in the United Kingdom in 1926 and became the major supplier of flying jackets to the Royal Air Force during most of the Second World War.
The two most historical and renowned American flight jackets are the A-2 jacket and the G-1. Not only these two jackets were useful to the serving men who wore them, but in their reputation they became symbols of honor, adventure, and style.
Today flight jackets are usually connected with the MA-1, a U.S. military jacket, which is mostly found in black or sage green.

Gasoline

Gasoline engines have the benefit over diesel in being lighter and able to work at higher rotating speeds and they are the usual choice for fitting in high presentation sports cars. Continuous development of gasoline engines for over a hundred years has formed improvements in efficiency and reduced pollution. The carburetor was used on nearly all road car engines awaiting the 1980s but it was long realized better control of the fuel/air mixture could be achieved with fuel inoculation.

Indirect fuel injection was initially used in aircraft engines from 1909, in racing car engines from the 1930s, and road cars from the late 1950s. Gasoline Direct Injection (GDI) is now starting to appear in making vehicles such as the 2007 BMW MINI. Wear out gases are also cleaned up by appropriate a catalytic converter into the tire out system. Clean air legislation in many of the car industries most important markets have made both catalysts and fuel injection virtually common fittings. Most modern gasoline engines are also able of running with up to 15% ethanol mixed into the gasoline - older vehicles may have seals and hoses that can be wounded by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentration as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be in progress on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engine cars can also run on LPG with the addition up of an LPG tank for fuel storage and carburetion modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork lift trucks that have to activate inside buildings
