An overview about the Traffic light

A traffic light or traffic signal is a signaling machine positioned at a road intersection or pedestrian crossing to point out when it is secure or safe to drive, ride or walk, using a worldwide color code.

The Traffic lights for common vehicles or pedestrians for all time have two main lights, a red one that means stop and a green one that means go. Generally, the red light contains some orange in its hue, and the green light has some blue, to give some support for people with red-green color blindness. In nearly all countries there is also a yellow (or amber) light, which when on and not flashing means halt if able to do so securely. In some systems, flashing amber means that a motorist can go ahead with care if the road is clear, giving way to pedestrians and to other road vehicles that possibly will have priority. A flashing red basically means the same as a regular stop sign. There can be added lights (generally a green arrow or "filter") to approve turns (called a lead light in the U.S., because it is generally leading the main green light). Traffic lights for particular vehicles (like buses or trams) may perhaps use other systems, like vertical vs. horizontal bars of white light.

Different Glass Colors information

The Metallic additives in the glass mix can make various colors. Here cobalt has been added to produce a bluish colored attractive glass Metals and metal oxides are added to glass during its manufacture to change its color. Manganese can be added in small amounts to take away the green tint lent by iron, or in higher concentrations to provide glass an amethyst color.

Similar to manganese, selenium can be used in small concentrations to decolorize the glass, or the higher concentrations to impart a reddish color. Small concentrations of the cobalt (0.025 to 0.1%) will yield blue glass. The Tin oxide with antimony and arsenic oxides make an opaque white glass, first used in Venice to make imitation porcelain. 2 to 3% of the copper oxide produces a turquoise color. Pure metallic copper produces an extremely dark red, opaque glass, which is at times used as a substitute for gold ruby glass. Nickel, depending on the concentration, will produces blue, or violet, or even black glass too.

Adding titanium makes the yellowish-brown glass. Metallic gold, in very small concentrations (around 0.001%), will makes a rich ruby-colored glass, while lower concentrations will makes a less intense red, often marketed as "cranberry". Uranium (0.1 to 2%) can be added to give glass a glowing yellow or green color. Uranium glass is normally not radioactive enough to be dangerous, but if ground into a powder, for example by polishing with sandpaper, and inhaled, it can be carcinogenic. Silver compounds (especially silver nitrate) can make a variety of colors from orange-red to yellow. The way the glass is heated and cooled can notably affect the colors shaped by these compounds. The chemistry concerned is complex and not well understood.

The real facts about Earth

Earth is the third planet from the Sun and the fifth largest of the planet. Earth is the only planet whose English name does not originate from Greek/Roman mythology. The name derives from Old English and Germanic.

Earth, for sure, can be studied without the aid of spacecraft. However it was not until the twentieth century that we had maps of the complete planet. Pictures of the planet taken from space are of significant importance; for instance, they are a huge help in weather prediction and especially in tracking and predicting hurricanes. And they are amazingly beautiful. The Earth's magnetic field and its relations with the solar wind also generate the Van Allen emission belts, a pair of doughnut shaped rings of ionized gas (or plasma) trapped in orbit just about the Earth. The outer belt stretches from 19,000 km in altitude to 41,000 km; the inner belt lies involving 13,000 km and 7,600 km in altitude.

The Earth's surface is extremely young. In the relatively short (by astronomical standards) time of 500,000,000 years or so erosion and tectonic processes destroy and remake most of the Earth's surface and thus eliminate almost all traces of earlier geologic surface history (such as impact craters). Thus the very early on history of the Earth has mostly been erased. The Earth is 4.5 to 4.6 billion years old, but the oldest recognized rocks are about 4 billion years old and rocks older than 3 billion years are rare. The oldest fossils of existing organisms are less than 3.9 billion years old. There is no evidence of the critical period when life was first getting in progress.

The Earth's atmosphere is 77% nitrogen, 21% oxygen, with draws of argon, carbon dioxide and water. There was perhaps a very much larger amount of carbon dioxide in the Earth's atmosphere when the Earth was first created, but it has since been nearly all incorporated into carbonate rocks and to a smaller extent dissolved into the oceans and consumed by living plants. Plate tectonics and biological processes now keep a repeated flow of carbon dioxide from the atmosphere to these various "sinks" and back over again. The small amount of carbon dioxide occupant in the atmosphere at any time is very important to the maintenance of the Earth's surface temperature through the greenhouse effect. The greenhouse effect raises the average surface temperature regarding 35 degrees C above what it would if not be (from a frigid -21 C to a comfortable +14 C); without it the oceans would freeze and life as we know it would be impossible.

A Cure for Cancer

Over twenty special types of cancer have been established to exist in the world today. Cancer kills over thousands of people in the united state all the year. The news constantly contains reports of the many types of ways a human can get cancer. The main reasons one can get cancer by smoking, dietary factors, exercise, occupation, genetics etc, Out of that the main cause of cancer obesity and smoking are the leading causes. Cancer affects a person when abnormal cells within a tissue of a certain part of the human body carry on dividing out of control. Normal cells stop reproduce after about fifty cycles. Since many types of cancer live, anyone at any age has a risk of being diagnose.
In an effort for people to speed up the process of finding a cure for cancer, people came up with urban mythology and myths to preventing or getting rid of cancer. In the spring of 1999 many people begin to believe that antiperspirants could cause cancer. The Canola oil, which is said to by scientists to be one of the healthier food oils, was also once supposed to be toxic and cancer causing.

Adam Sandler: the Funniest man Alive!

With a hazardous brand of humor that has brought him legions of dedicated fans, Sandler's hit as an actor, stand-up comic, writer and producer is matched by his performance and songwriting skills. It is an shocking gift for lyric and melody that is front and center on Adam Sandler's very funny new Warner Bros. Records release What is Your surname featuring 14 new Sandler originals include such classics as The Goat Song, the Lonesome Kicker, Bad Boyfriend and Corduroy Blues.

What is Your Name continues the musical tradition Sandler began with at a standard Pace, Ode to My Carnd the extremely popular The Chanukah Song. With two platinum-selling, Grammy-nominated albums - They're All Gonna Laugh at you and What the Hell Happened to Me - Already to his credit, Sandler goes for a comedy-three peat with what’s Your Name. The move to an all-music format is a normal one, following his 21 city tour last summer, when he perform both creative material and his favorite childhood tunes, backed by a finest rock and roll band.

Flak jacket

A flak jacket or flak vest is a type of caring clothing. Today it frequently refers to bulletproof vests, particularly Type III and on top of which have added steel, titanium, ceramic or polyethylene saucers which can resist high-powered rounds such as from rifles.

Currency

A currency is a component of exchange, facilitating the transfer of supplies and services. It is a form of money, where money is an 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.

Count wheel

Count wheel striking: the unequally spaced notches in the external count wheel on the right side of this tower clock movement regulate the number of times the bell is struck. Two technologies have been devised by clockmakers to enable striking clocks to correctly count out the hours. The earlier technology is called count wheel striking. This uses a wheel that contains notches on its side, spaced by unequal, increasing arc segments. This count wheel governs the rotation of the striking train. When the striking train is released by the timekeeping train, a lever is lifted from a notch on the count wheel; the uneven notches allow the striking train to move only far enough to sound the correct number of times, after which the lever falls back into thatch and stops the striking train from turning further.

Harrington jacket

A Harrington jacket is a type of tiny, lightweight jacket, made of cotton, polyester, wool or suede — generally with a tartan or check-patterned lining.

The initial Harrington-style jackets were made by British clothing company, Baracuta, in the 1930s; the company is still making the same model, the G9. This style of jacket got the nickname Harrington because it was worn by the personality Rodney Harrington (played by Ryan O'Neal) in the 1960s television program Peyton Place; John Simmons, who opened 'The Ivy Shop', Richmond, London, claims to have coined this explanation.

Toothbrush

The toothbrush is a device used to clean teeth, consisting of a tiny brush on a handle. Toothpaste, often containing fluoride, is commonly added to a toothbrush to assist in cleaning. Toothbrushes are offered with changeable textures of bristles, and come in many different sizes and forms. Most dentists recommend using a toothbrush labeled "Soft", since firmer bristled toothbrushes can harm tooth enamel and irritate gums as indicated by the American Dental Association. Toothbrushes are often ready from synthetic fibers, although natural toothbrushes are also known in many parts of the world.

Electrostatic

A thin, electrostatic ally charged diaphragm, is suspended between two perforated metal plates. The electrical sound signal is applied to the electrodes creating an electrical field; depending on the polarity of this field, the membrane is drawn towards one of the plates. Air is forced through the perforations; combined with a continuously changing electrical signal oscillating the membrane, a sound wave is generated.

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.

Pollarding

Pollarding is a woodland management method of hopeful lateral branches by cutting off a tree stem or minor branches two metres or so above ground level. The tree is given a year to regrow, after the first cutting, but once begun, pollarding requires annual maintenance by pruning. This will ultimately result in somewhat expanded (or swollen) nodes topping the tree trunk with multiple new side and top shoots growing from it.A tree that has been pollarded is known as a pollard. A tree which has not been pollarded is called a maiden or maiden tree; which also refers to the fact that pollarding is usually first undertaken when the tree is quite young. Pollarding older trees typically result in the death of the tree. Pollarding is sometimes abused in attempts to curb the growth of older or taller trees. However, when performed properly it is useful in the practice of arboriculture for tree management.

Deadheading

Deadheading is the act of removing spent flowers or flowerheads for aesthetics, to prolong bloom for up to several weeks or endorse rebloom, or to put off seeding.Deadheading is beneficial to most herbaceous ornamental plants. It can get better overall look of a plant, give a fresh new look to an otherwise finished or even distracting item, and can promote vegetative and root increase rather than seed production and help retain the plant's healthy appearance.

Bean

Bean is a common name for large plant seeds of several genera of Fabaceae used for food or feed. They are also known as legumes.The term Bean at first referred to the seed of the broad bean, but was later broadened to include members of the genus Phaseolus such as the common bean or haricot and the runner bean and the related genus Vigna. The term is now applied in a general way to many other related plants such as soybeans, peas, lentils, kidney beans, vetches and lupins.Bean can be used as a near synonym of pulse, an edible legume, though the term "pulses" is usually reserved for leguminous crops harvested for their dry grain. Pulses frequently exclude crops mainly used for oil extraction (like soybean and peanut) or those used exclusively for sowing purposes (clover and alfalfa). Leguminous crops harvested green for food, such as snap beans, green peas etc, are classified as vegetable crops.In English usage 'beans' sometimes also refer to seeds or other organs of non leguminosae which bear a resemblance to the vegetable, for example coffee beans, castor beans and cocoa beans ,and vanilla beans .

Solar System

Solar System consists of the Sun and the other space objects gravitationally bound to it: the eight planets, their 162 known moonsthree currently recognized dwarf planets (including Pluto) and their four known moons, and billions of small bodies. This last group includes asteroids, Kuiper belt objects, comets, meteoroids and interplanetary dust.

In wide terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, collected of icy objects. Beyond the Kuiper belt lies the scattered disc, the heliopause, and eventually the hypothetical Oort cloud.

In sort of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Six of the eight planets are in turn orbited by natural satellites, usually termed "moons" after Earth's Moon, and each of the outer planets is encircled by planetary rings of dust and other particles. All the planets apart from Earth are named after gods and goddesses from Greco-Roman mythology. The three dwarf planets are Pluto, the largest known Kuiper belt object; Ceres, the largest object in the asteroid belt; and Eris, which lies in the scattered disc.

Butterfly Koi

Butterfly Koi, Longfin Koi, or Dragon Carp are a type of ornamental fish notable for their elongated finnage. The fish are a breed of the common carp, Cyprinus carpio, (which includes numerous wild carp races as well as domesticated koi ("Nishikigoi").

Butterfly Koi originated in the mid 20th century as a result of an effort to increase the hardiness of traditional koi. Japanese breeders interbred wild Indonesian Longfin river carp with traditional koi. The resulting fish had longer fins, long barbells, pompom nostrils, and were hardier than koi. These were known in Japan as “onagaoi” or "hire naga koi", or translated in English “long tail koi”. Randy LeFever, the son of Wyatt LeFever, a noted breeder of koi, is credited with suggesting they looked like butterflies, a trait for which the breed is named. They are also sometimes referred to as Dragon Koi.

Blue rose

Since roses lack a gene to create delphinidin, the primary plant pigment that produces true blue flowers, blue roses were usually created by dyeing white roses. So-called "blue roses" have been breed by conventional hybridization methods, but the results, such as "Blue Moon" are more precisely described as lilac in color. However, after 13 years of joint research by an Australian company Florigene, and Japanese company Suntory, a blue rose was formed in 2004 by genetic engineering. The delphinidin gene was cloned from the petunia and inserted into a mauve-blend rose, the Old Garden Rose 'Cardinal de Richelieu.' (a Rosa gallica) However, since the pigment cyanidin was still present, the rose was more dark burgundy than true blue. Further work on the rose using RNAi technology to depress the production of cyanidin produced a very dark mauve plant, with only trace amounts of cyanidin.
Blue roses conventionally signify mystery or attaining the impossible. They are supposed to be able to grant the owner youth or grant wishes. This symbolism derives from the rose's meaning in the language of plants common in Victorian times.

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 Hertzsprung-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
