Car Albums in 1978’s

The band's hits dominated the charts for over nine years; their most victorious albums were 1978's The Cars, which featured hit "Just What I Needed," and 1984's Heartbeat City, which included four Top 20 singles: "Magic," "Drive," "Hello Again," and "You Might Think," which also won the MTV Video of the Year Award . "Drive" gained fastidious notability when it was used in a video of the Ethiopian food shortage prepared by the Canadian Broadcasting Corporation and introduced by David Bowie at the 1985 Live Aid concert at Wembley Stadium.

After the consequential period of superstardom and another hit single, the Cars released their last album Door to Door in 1987, but it failed to approach the success of their previous albums. The Cars announced the group's disintegrate in February 1988. In the late 1990s, rumors circulated of a Cars reunion, but Orr's death of pancreatic cancer on October 3, 2000 position an end to them.

Starting in late 2004, The Cars punch song "Just What I Needed" was played in Circuit City

television ads.

The Cars were an American new wave band, one of the most admired to emerge out of the early punk scene in the late 1970s. They hailed from Boston, Massachusetts and were signed to Elektra report in 1977.

The band's members were Ric Ocasek (born Richard Otcasek), the band's principal songwriter, rhythm guitarist, and part-time lead singer; Benjamin Orr (born Benjamin Orzechowski), bassist and recreational lead singer; Elliot Easton, lead guitar and backing vocals; David Robinson, drums and backing vocals; and Greg Hawkes, keyboards, saxophone, guitar, and backing vocals. The nucleus of the assemblage was composed of guitarists Ocasek and Orr.

The Cars productively bridged the gap between the guitar-oriented rock of the 1970s and the synth-oriented pop of the early 1980s. While most of the singles included an Elliot Easton guitar solo, The Cars' sound was distinct much more by Greg Hawkes' synthesizers and the huge harmonies of Easton, Robinson, and Hawkes behind Orr's and Ocasek's lead vocals.

Collective and non-human intelligence

Some thinkers have explored the idea of combined intelligence, arising from the coordination of many people.

A battleship, for instance, cannot be operated by a single person's knowledge, actions and intelligence, it takes a corresponding and interacting crew.

Similarly, the interesting behaviors of a bee colony are not exhibited in the intelligence and actions of any lone bee, but rather manifested in the behavior of the hive.

These ideas are explored as a foundation for human thought, with applications for artificial intelligence (AI), by MIT AI pioneers Norbert Wiener and Marvin Minsky. Artificial intelligence (AI) has emerged from Computer science as a specialty which seeks to make computers do something in increasingly intelligent ways, and provides insights into human thought processes.

When considering animal intelligence, a more common definition of intelligence might be applied: the "ability to adapt effectively to the environment, either by making a change in oneself or by changing the environment or finding a new one" (Encyclopædia Britannica).

Many people have also speculated about the opportunity of extraterrestrial intelligence.

Intelligence, IQ, and g

Intelligence, IQ, and g are very different. Intelligence is the term used in ordinary discourse to refer to cognitive ability.

However, it is usually regarded as too imprecise to be useful for a scientific treatment of the subject. The intelligence quotient (IQ) is an index calculated from the scores on analysis items judged by experts to encompass the abilities coverd by the term intelligence.

IQ measures a multidimensional magnitude: it is an amalgam of dissimilar kinds of abilities, the proportions of which may differ between IQ tests.

The dimensionality of IQ scores can be premeditated by factor analysis, which reveals a single dominant factor underlying the scores on all IQ tests.

This factor, which is a hypothetical construct, is called g. Variation in g corresponds very much to the intuitive notion of intelligence, and thus g is sometimes called general cognitive ability or general intelligence.

Artificial intelligence

Artificial intelligence (also known as machine intelligence and often abbreviated as AI) is intelligence exhibited by any contrived (i.e. artificial) system. The term is often applied to common purpose computers and also in the field of scientific investigation into the theory and practical application of AI. "AI" the name is often used in works of science fiction to refer to that which exhibits artificial intelligence as well, as in "the AI" referring to a singular discrete or distributed mechanism. Modern AI research is disturbed with producing useful machines to automate human tasks requiring intelligent behavior. Examples include: scheduling resources such as military units, answering questions about products for customers, thoughtful and transcribing speech, and recognizing faces in CCTV cameras.

As such, it has become an engineering control, focused on providing solutions to practical problems. AI methods were used to plan units in the first Gulf War, and the costs saved by this efficiency have repaid the US government's entire investment in AI research since the 1950s. AI systems are now in routine use in many businesses, hospitals and military units approximately the world, as well as being built into many common home computer software applications and video games. (See Raj Reddy's AAAI paper for a complete review of real-world AI systems in deployment today.) AI methods are often employed in cognitive science research, which openly tries to model subsystems of human cognition.

A camera is a mechanism used to take pictures, either singly or in sequence, with or without sound, such as with video cameras. The name is derivative from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an entire room functioned much as the interior workings of a modern photographic camera, except there was no way at this time to record the image short of manually tracing it. Cameras may work with the visual range or other portions of the electromagnetic spectrum.

Every camera consists of some type of enclosed chamber, with an opening or space at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. This distance of the aperture is often controlled by an diaphragm mechanism, but some cameras have a fixed-size aperture.

Corbett's Tiger

Indochinese Tiger The Indochinese tiger (Panthera tigris corbetti), also called Corbett's tiger, is originate in Cambodia, China, Laos, Myanmar, Thailand, and Vietnam, preferring to stay alive in forests in mountainous or hilly regions. Estimates of its inhabitants vary between 1,200 to 1,800, with only several hundred left in the wild, but it seems likely that the number is in the lower part of the range; it is considered Endangered. The largest present population is in Malaysia, where illegal poaching is strictly controlled, but all existing populations are at extreme risk from habitat fragmentation and inbreeding. In Vietnam, nearly three-quarters of the tigers killed provide stock for Chinese pharmacies. Also, the tigers are seen by poor natives as a resource through which they can ease poverty. Indochinese tigers are less significant and darker than Bengal tigers. Males weigh up from 150–190 kg (330–420 lb) on average while females are smaller at 110–140 kg (242–308 lb). Their go on a diet consists of wild pigs, cattle and deer; The Indochinese tiger is a carnivore.

Tiger’s in India

Even though this is the most 'common' tiger, these tigers are under severe force from both habitat destruction and poaching. In 1972, India launched a huge wildlife conservation project, known as Project Tiger, to care for the depleting statistics of tigers in India. The project helped raise the population of these tigers from 1,200 in the 1970s to 3,000 in the 1990s and is considered as one of the most successful wildlife conservation programs. At least one Tiger Reserve has lost its full tiger population to poaching. Males in the wild generally weight 205 to 227 kg (450–500 lb), while the average female will weigh about 141 kg. However, the northern Indian and the Nepalese Bengal tigers are invented to be somewhat bulkier than those found in the south of the Indian Subcontinent, with males averaging around 520 lbs (236 kg).

Subspecies of Tiger

There are nine recent subspecies of tiger, three of which are extinct, one of which is nearly certain to become extinct in the near future, and five of which still occur. Their chronological range ran through Russia, Siberia, Iran, Afghanistan, India, China and south-east Asia, including the Indonesian islands. These are the ongoing subspecies, in descending order of wild population:

Bengal tiger

The Bengal tiger or the Royal Bengal tiger (Panthera tigris tigris) is originate in parts of India, Bangladesh, Nepal, Bhutan and Myanmar. It lives in different habitats: grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangroves. The Indian government's estimated populace figure for these tigers is between 3,100 and 4,500, some 3,000 of which are found in India alone. However, many Indian tiger conservationists uncertainty this number, seeing it as overly optimistic. The number of Bengal tigers in India may be less than 2,000, as most of the collected statistics are based on pugmark identification, which often gives a biased result.

Tiger's eye

Tiger's eye (also Tigers eye, Tiger eye) is a chatoyant gemstone that is generally yellow- to red-brown, with a silky luster. It is a rubbery silicified crocidolite (blue asbestos), a classic model of pseudomorphous replacement. An incompletely silicified blue option is called Hawk's eye. A member of the quartz group, its physical and optical properties are the same or very near to those of single-crystal quartz.

The gems are generally cut en cabochon in order to best display their chatoyancy. Red stones are brought about through calm heat treatment. Honey-coloured stones have been used to try to be like the much higher valued cat's eye chrysoberyl (cymophane), but the overall effect is unconvincing. Artificial fibreoptic glass is a general imitation of tiger's eye, and is produced in a wide range of colours.

Naming and etymology of Tiger

The word "tiger" is taken from the Greek word "tigris", which itself is consequential "possibly from an Iranian source." In American English, "Tigress" was first record in 1611. "Tiger's-eye" is a name for a golden-brown with stripes, chatoyant, fibrous assortment of quartz used as a semi-precious gemstone. It was one of the lots of species formerly described, as Felis tigris, by Linnaeus in his 18th century work, Systema Naturae. The generic factor of its scientific designation, Panthera tigris, is often presumed to derive from Greek pan- ("all") and ther ("beast"), but this may be a folk etymology. Although it came into English from side to side the classical languages, panthera is probably of East Asian origin, meaning "the yellowish animal," or "whitish-yellow".

Monday, October 08, 2007


The tiger (Panthera tigris) is a animal of the Felidae family, the largest of four "huge cats" in the Panthera genus. Native to the mainland of Asia, the tiger is an top predator and the largest graceful species in the world, comparable in size to the biggest fossil felids. The Bengal Tiger is the most common subspecies of tiger, constituting something like 80% of the entire tiger population, and is found in India, Bangladesh, Bhutan, Myanmar and Nepal. It has disappeared from much of its previous circulation including the Caucasus, Java and Bali.

The tiger is an endangered variety, with the majority of the world's tigers now living in captivity.Several subspecies are extinct and others critically in danger of extinction. Tigers have featured in ancient mythologies and tradition, and continue to be depicted in modern films and literature, as well as appearing on flags, coats of arms and as mascots for sporting teams. It is the national animal of India, among other countries.

Postal Marking

A postal marking is any kind of marginal note applied to a letter by a postal service. The most frequent types are postmarks and cancellations; almost every letter will have those, less common types include forward addresses, routing annotations, warnings, postage due notices and explanations, such as for smashed or delayed mail. A key part of postal history is the credit of postal markings, their purpose, and period of use.

Service marks give in sequence to the sender, recipient, or another post office. Advice marks notify about forwarding, miss ending, letters received in bad condition, letters received too late for delivery by a certain time, or the reason for a delay in mail delivery. Dead letter offices would use a variety of markings to keep track of their progress in finding the addressee, such as a notation that the letter had been advertise in the local newspaper. The tracking process for register mail may entail many marks and notations.

Shortly after the eruption of the American Civil War, the Northern authorities affirmed the existing postage stamps invalid and issued new types. Letters using the demonetized stamps received a marking "OLD STAMPS NOT RECOGNIZED", an accidentally humorous comment much prized by collectors today.

Abstract art

Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses color 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, which 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.

Salwar kameez

Salwar kameez is also spelled shalwar kameez and shalwar qamiz is a traditional dress worn by both women and men in Pakistan, India, Bangladesh, and Afghanistan. It is now and then known as Punjabi suit due to its popularity in the Punjab region and the Pathani suit, due to the fact that the Pathans of Kabul introduce the dress to the rest of South Asia.

It is loose pajama like trousers the legs are wide at the top and narrow at the bottom,
The kameez is a long shirt or tunic. The part seams known as the chaak are left open below the waist-line, which gives the wearer greater freedom of movement. In Afghanistan and Pakistan, it is the favored garment of both sexes. In Bangladesh and India, it is most normally a woman's garment. Though the majority of Indian women wear traditional clothing, the men in India can be found in more conservative western clothing. Shalwar kameez is the traditional dress worn by a variety of peoples of south-central Asia. In India and Pakistan it is a particularly popular style of dress. Shalwar or Salwar is a short loose or parallel trouser.

Rainbows are optical and meteorological phenomena that reason of a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicolored arc, with red on the external part of the arch and violet on the inner section of the arch. More rarely, a secondary rainbow is seen, which is a second, fainter arc, outside the primary arc, with colours in the differing order, that is, with violet on the outside and red on the inside.

A rainbow spans a permanent spectrum of colours. Traditionally, however, the chain of colours is quantized. The majority cited and remembered sequence, in English, is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet. "Roy G. Biv" and "Richard of York Gave Battle In Vain" are admired mnemonics.

Though rainbows are bow-shaped in most cases, there are also phenomena of rainbow-colored flooring in the sky: in the shape of stripes, circles, or even flames

Pollution is the opening of pollutants chemical substances, noise, heat, light, energy and others into the environments which effect in deleterious effects of such a nature as to cause danger to human health, harm living resources and ecosystems, and impair or interfere with amenities and other legitimate uses of the environment Pollution is formed by vehicle which make the health spoil.

Sunday, August 26, 2007


Pulses are defined by the Food and Agricultural Organization of the United Nations (FAO) as yearly leguminous crops yielding from one to twelve grains or seeds of variable size, shape and color surrounded by a pod. Pulses being used for food and animal feed.

The term pulses, as used by the FAO, are kept for crops harvested solely for the dry grain. This therefore excludes green beans and green peas, which are measured vegetable crops. Also barred crops which are mainly grown for oil extraction oilseeds like soybeans and peanuts, and crops which are used exclusively for sowing (clovers, alfalfa).

Pulses are main food crops due to their high protein and necessary amino acid content. Like many leguminous crops, pulses play a key role in crop turning round due to their capability to fix nitrogen.

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.

Fuel and propulsion technologies

Most automobiles in use nowadays are propelled by gasoline is also known as petrol or diesel internal combustion engines, which are known to reason for air pollution and are also blamed for contributing to climate change and global warm. Increasing costs of oil-based fuels and tapering environmental laws and restrictions on greenhouse gas emissions are propelling work on substitute power systems for automobiles. Efforts to get better or replace these technologies include hybrid vehicles, electric vehicles and hydrogen vehicles.

Early Stages of a pregnant woman and her health

Pregnancy is not an easy job for a woman. Starting from conception to birth, a woman's body carries out the most miraculous process of fertilization, implantation and the maturity and growth of her baby (or babies). Her body is her baby's dwelling place for the next nine months (or around 40 weeks) and the occurrences of pregnancy turn into a journey of many new physical feelings. Whether it is first, second, third (or more) pregnancy, her body will respond in a different way to each individual pregnancy. So health of a pregnant woman is very important to be taken care of.

Throughout the first 12 weeks of pregnancy called the '1st trimester’, a woman's body adjust to present a fostering and protective environment for her baby to grow and develop. Seldom, the early signs of pregnancy can make a woman feel puzzled. This may be for the reason that many of the physical signs of in the early hours of pregnancy such as enlarged tender breasts, sensitivity of tiredness, overstuffed and perhaps experiencing spasms and/or pelvic uneasiness can be considered as normal pre-menstrual signs. In all these stages the health of the woman declines because she is not only feeding herself, also her little developing fetus.

They may also sense disgusted or sick, due to morning sickness. It is not unusual to feel unsure about what is 'normal' during the early stages of pregnancy development, and unfamiliar signs or sensations may trigger concerns about the health, of her and baby. It’s been proved by the Gynecologists that every woman's body will react in a different way to being pregnant. Many women find their early pregnancy symptoms very difficult to cope with, both at work and generally.

Due to continuous vomiting and nourishing the fetus the pregnant woman may be exhausted very easily. She has to constantly keep her energetic by maintaining a healthy diet schedule as prescribed by the physicians. She can have more fresh green vegetables and fruit juices to make her feel fresh and energetic. It’s always significant to make sure that she avoids drinking and smoking because whatever she has will be directly absorbed by the baby. Once the fetus starts developing she has to get primed for all the obstacles she has to experience throughout pregnancy. Many psychologists predict that a healthy pregnancy is not only from taking care of the nutrition for the pregnant women, more than that she has to be taken care from all the hassles in her family. It’s the duty of a loving husband to caress her comfortably and keep her happy always throughout the gestation period. This will not only make the woman feel happy and hopeful it will directly lead to the good development of the fetus.

Mobile phone

The introduction of cells for mobile phone base stations, invented in 1947 by Bell Labs engineers at AT&T, was further industrialized by Bell Labs during the 1960s. Due to their low establishment expenses and fast exploitation, mobile phone networks have since spread hastily throughout the world, outstripping the growth of fixed telephony.

The zero generation (0G) of mobile telephones was introduced in 1945. 0G mobile telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since they did not sustain the automatic change of channel frequency during calls, which allows the user to shift from one cell (the base station coverage area) to another cell, an attribute called "handover".

The first marketable cellular network was launched in Japan by NTT in 1979. Fully automatic cellular networks were first introduced in the beginning to mid 1980s (the 1G generation) with the Nordic Mobile Telephone (NMT) system in 1981. This was followed by an explosion in mobile telephone habit, particularly in Northern Europe.

The first "modern" network technology on digital 2G (second generation) cellular technology was launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard which also striking the beginning of competition in mobile telecoms when Radiolinja challenged current Telecom Finland (now part of TeliaSonera) who ran a 1G NMT network. A decade after, the first commercial commence of 3G (Third Generation) was again in Japan by NTT DoCoMo on the WCDMA standard. However, Martin Cooper, a Motorola engineer, is accredited with the innovation of the modern mobile phone in the 1990s. Until the early 1990s, most mobile phones were too large to be carried in a jacket pocket, so they were normally installed in vehicles as car phones. With the miniaturization of digital apparatus, mobile phones have become more and handier over the years.

The term "conception" commonly refers to fertilization, but is sometimes defined as implantation or even "the point at which human life begins," and is thus a subject of semantic arguments about the beginning of pregnancy, within the abortion deliberate. Gastrulating is the point in development when the implanted blast cyst develops three germ layers, the endoderm, the exoderm and the mesoderm. It is at this point that the inherited code of the father becomes fully occupied in the development of the embryo. Until this point in development, twinning is probable. Additionally, interspecies hybrids which have no chance of growth survive until gastrulation. However this stance is not entirely necessary since human developmental biology literature refers to the "concepts" and the medical literature refers to the "products of conception" as the post-implantation embryo and its surrounding membranes. The term "conception" is not generally used in scientific literature because of its variable definition and suggestion.

Nonfood uses

Because fruits have been such a major part of the human diet, different cultures have urbanized many different uses for various fruits that they do not depend on as being edible. Many dry fruits are used as streamer or in dried flower arrangements, such as unicorn plant, lotus, wheat, annual honesty and milkweed. Ornamental trees and shrubs are frequently refined for their colorful fruits, as well as holly, pyracantha, viburnum, skimmia, beautyberry and cotoneaster.

Fruits of opium poppy are the basis of the drugs opium and morphine. Osage orange fruits are used to keep away cockroaches. Bayberry fruits provide a wax frequently used to make candles. Many fruits give natural dyes, e.g. walnut, sumac, cherry and mulberry. Dried up gourds are used as streamer, water jugs, bird houses, musical instruments, cups and dishes. Pumpkins are imprinted into Jack-o'-lanterns for Halloween. The spiny fruit of burdock or cocklebur were the motivation for the invention of Velcro.

Coir is a fiber from the fruit of coconut that is used for doormats, brushes, mattresses, floortiles, sacking, lagging and as a growing medium for container plants. The shell of the coconut fruit is used to make memento heads, cups, bowls, musical instruments and bird houses.

Wakeboard Boats have a device that creates a huge wake for a skier to jump the wakes from face to face doing aerial tricks. Wakeboard complete boats are Drive boats. This means they are an inboard boat among the engine place backwards in the nurture of the boat. Some wakeboard detailed boat models are direct drive boats where the engine is in the center of the boat. Most wakeboard boats will have some features that help to make large wakes. Ballast, lodge, and hull technology. Most new wakeboarding boats come usual with some sort of regular ballast. Generally, these ballast tanks are placed inside of the hull of the boat and can be crowded and empties by switches situated in the drivers area. The ballast weights the boat down, creating a larger wake when in proposition. The Wedge is a machine that helps shape the wake. It is a metal structure situated behind the propeller that helps the driver fine melody the wake for the athlete. Hull technology is the innovation and R&D that the manufacturers put into their boats to make sure the best stock wake possible. Many boarders use after market ballast and guide to further weight down their boats for very huge wakes or for sports such as wake surfing.

A trawler is a fishing boat designed for the purpose of operating a trawl, a type of fishing net that is dragged along the underneath of the sea (or sometimes above the bottom at a specified depth).
A trawler can also refer to a cruising trawler which is a recreational boat as it resembles a fishing trawler.
Modern "rock hopper" nets have heavy rubber wheels that allow the net move slowly over rough ocean bottoms without tearing on rocks.
Sailing trawlers can trawl at depths of 55-75 metres, but modern trawlers can often trawl to 900 metres. Sizes of modern trawlers vary from 2,500 to 3,000 tons.
Fishing trawler,made up of wood was invented in Brixham(in England) in 19th century, which is the largest port in the South-West .

A pontoon is a flat-bottomed boat or the floats used to support an arrangement on water. It may be simply constructed from closed cylinders such as pipes or barrels or made-up of boxes from metal or concrete. These may be worn to support a simple platform, creating a raft. A raft supporting a house-like structure is single form of houseboat.
Pontoon boats usually run slower and are less likely to cause harm to themselves or other vessels, and are thus less luxurious to insure. As such, they are the most admired vessel style for rental operations. They also present the largest value in terms of capacity to price.

His longboat should not be confused with a Long ship; or with a narrow boat. In the days of sailing ships, a vessel would take a number of boats for various uses. One would be a longboat, an open, mainly rowing boat with eight or ten oarsmen, two per spoil. In other words the longboat was double banked: its rowing benches were planned to accommodate two men. Unlike the vessel or the cutter, the longboat would have quite fine lines aft to permit its use in steep waves such as surf or wind against tide where need be.
It had the double-banked understanding in common with the cutter. This was possible as it had a beam alike to a cutter's but broader than that of a gig, which was solitary banked. The longboat was frequently more seaworthy than the cutter which had a fuller stern for such load-carrying work as laying out an anchor and cable. In a seaway or surf therefore, the cutter was more flat to broaching to.

A ketch is a marine craft with two masts: a main mast, and a shorter mizzen mast abaft (rearward of) the main mast. Both masts are rigged mostly fore-and-aft. From one to three jibs may be approved forward of the main mast when going to windward. If a ketch is not rigged for jibs is known as cat ketch, sometimes called per auger. On older, larger ketches the major mast may in addition carry one or more square rigged topsails, alike to a sloop. A ketch may also carry further sails, see below.

The lowest fore-and-aft sail on the major mast is called the mainsail, while that on the mizzen is called the mizzen sail. These may be any kind of fore-and-aft sail, in any grouping. The Scots Zulu, for example, had a dipping lug main with a position lug mizzen.
The ketch is popular among long distance cruisers as the additional sail allows for a better balance, and a smaller more simply handled mainsail for the same overall sail area. It also allows sailing on mizzen and jib only without introducing extreme lee helm, and in an emergency can be quite well steered without use of the rudder.

It is a boat with wing-like foils mounted on struts under the hull. As the craft put into its speed the hydrofoils make better enough lift for the boat to become foil borne - i.e. to raise the hull up and out of the water. This consequence has a great decrease in drag and a corresponding increase in speed.
Early hydrofoils worn U-shape foils. Hydrofoils of this type are recognized as surface-piercing since portions of the U-shape hydrofoils will rise over the water surface when foil borne. Modern hydrofoils make use of T-shape foils which are fully submerged. Fully submerged hydrofoils are fewer subjected to the effects of wave action, and are therefore steadier at sea and are more relaxed for the crew and passengers. This type of pattern, however, is not self-stabilizing. The angle of attack on the hydrofoils wants to be adjusted endlessly in accordance to the changing conditions, a control process that is performed by computers. Failure to make the proper adjustments will result in the foil borne hull dipping aggressively back into the sea.

Fishing boat

A fishing boat can range from two-person enjoyment fishing boats up to 7-8 ton commercial fishers that can drag in over a billion fish at one time. Island nations like Japan rely on the fishing industry to give food. Fishing is also well-liked in places like the U.S, where it is often done for sport rather than for food. Fishing is extremely fixed in the American culture.
A lot of marinas and harbors cater to fishing boats and sport boats. It is an extensive array of business that make its living helpful for and service this boating and fishing community. Both leisure fishermen and commercial enterprises share the majority harbors.

A hybrid vehicle (HV) is a vehicle that uses two different power sources such as:
* An on-board rechargeable energy storage system (RESS) and a fueled power source for means of transportation force
* Human powered bicycle with sequence assist
* A sail boat with electric control
The term the commonly refers to petroleum electric hybrid vehicle, also called Hybrid-electric vehicle (HEV) which use internal burning engines and electric batteries to power electric motors.
The term hybrid when used in relative with cars also has other uses. Prior to its modern meaning of hybrid force, the word hybrid was used in the United States to mean a vehicle of mixed countrywide origin; generally, a European car fitted with American mechanical components. This significance has fallen out of use. In the import scene, hybrid was often used to describe an engine swap. Some have also referred to flexible-fuel vehicles as hybrids because they can use a combination of different fuels — naturally gasoline and ethanol alcohol fuel.

A cold winter morning
I am lying on a white, sandy beach with the glowing sun beating down directly on my tanned summer body. I notice the beautiful, Puerto Rican Cabana boy heading over to replenish my newly empty Margarita glass. I look around my private beach and at the crystal clear, sparkling ocean water tempting me warmly in to its open arms. I get up from my bed on the sand, walking gradually to the water. The sand is flaming my bare feet with such passion that I speed my walk up almost into a jog. As I reach the waterfront I stop, as a falling wave is heading toward my glazing body; I step closer to be in its direct path. I move smoothly in with such grace; I prepare myself for the cool, refreshing bath. I hear an alarm bell screaming, I look around in a panic as it is hurting my ears and giving me a powerful headache. My beach is wandering away, and then it is gone. The ‘warmness my body feels is gone.
I open my eyes; I am gloomy, lifeless room. My alarm clock is going off and the sound can only be compared with exhausted your fingernails across a chalkboard.

Carts have been mention in journalism as far back as the second millennium B.C. The Indian sacred book Rig-Veda states that men and women are as corresponding as two wheels of a cart. Hand-carts pushed by humans have been used approximately the world. In the 19th century, for example, some Mormons traveling across the plains of the United States between 1856 and 1860 used handcarts.
Carts were often used for judicial punishments, both to transport the destined – a public humiliation in itself (in Ancient Rome defeated leaders were often carried in the victorious general's triumph) – and even, in England until its replacement by the whipping post under Queen Elizabeth I, to tie the condemned to the cart-tail and administer him or her a public whipping.

Colossus of Rhodes

The Colossus of Rhodes was a giant statue of the god Helios, erected on the Greek island of Rhodes by Chares of Lindos, a pupil of Lysippos, between 292 BC and 280 BC. It was roughly the same size as the Statue of Liberty in New York, although it stood on a lower platform. It was one of the Seven Wonders of the World.

Alexander the Great died at an early age in 323 BC without having had time to put into place any plans for his succession. Fighting broke out among his generals, the Diadochi, with three of them eventually divides up much of his empire in the Mediterranean area. During the fighting Rhodes had sided with Ptolemy, and when Ptolemy eventually took control of Egypt, Rhodes and Ptolemaic Egypt formed an alliance which controlled much of the trade in the eastern Mediterranean. Another of Alexander's generals, Antigonus I Monophthalmus, was upset by this turn of events. In 305 BC he had his son Demetrius invade Rhodes with an army of 40,000. However, the city was well defended, and Demetrius had to start construction of a number of massive siege towers in order to gain access to the walls.

Identical twins

Identical twins occur when a single egg is fertilized to form one zygote which then divides into two separate embryos. This is not considered to be a hereditary trait, but rather an anomaly that occurs in birthing at a rate of about 1:150 births worldwide, regardless of ethnic background. The two embryos develop into fetuses sharing the same womb. When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. Depending on the stage at which the zygote divides, identical twins may share the same amnion, which can cause complications in pregnancy.

For example, the umbilical cords of monoamniotic twins can become entangled, reducing or interrupting the blood supply to the developing fetus. About 50% of mono-mono twins die from umbilical cord entanglement. Monochorionic twins, sharing one placenta, usually also share the placental blood supply. These twins may develop such that blood passes disproportionately from one twin to the other through connecting blood vessels within their shared placenta, leading to twin-to-twin transfusion syndrome.

Metamorphosis is a biological course by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure through cell growth and differentiation. Some insects, amphibians, molluscs, crustaceans, echinoderms and tunicates undertake metamorphosis, which is usually accompanied by a change of habitat or behavior. Scientific usage of the term is exclusive, and is not applied to common aspects of growth, including rapid growth spurts. References to “metamorphosis” in mammals are imprecise and only colloquial.

Metamorphosis usually proceeds in distinct stages, usually starting with larva or nymph, optionally passing through pupa, and ending as adult. The immature stages of a species that metamorphoses are regularly called larva. But in the complex metamorphosis of many insect species, only the first stage is called a larva and sometimes even that bears a different name; the distinction depends on the nature of the metamorphosis.
