Software prototyping

The prototyping model is a software development process that begins with requirements collection, followed by prototyping and user evaluation. Often the end users may not be able to provide a complete set of application objectives, detailed input, processing, or output requirements in the initial stage. After the user evaluation, another prototype will be built based on feedback from users, and again the cycle returns to customer evaluation. The cycle starts by listening to the user, followed by building or revising a mock-up, and letting the user test the mock-up, then back.

In the mid-1980s, prototyping was seen as the solution to the problem of requirements analysis within software engineering. Prototypes are any form of deliverables that model an application allowing users to visualize the application that is not yet constructed. Prototypes help users get an idea of what the system will look like, and make it easier for users to make design decisions without waiting for the system to be built.

PCR optimization

PCR(polymerase chain reaction) can fail for various reasons, in part due to its sensitivity to contamination causing amplification of spurious DNA products. Because of this, a number of techniques and procedures have been developed for optimizing PCR conditions. Contamination with extraneous DNA is addressed with lab protocols and procedures that separate pre-PCR reactions from potential DNA contaminants. This usually involves spatial separation of PCR-setup areas from areas for analysis or purification of PCR products, and thoroughly cleaning the work surface between reaction setups. Primer-design techniques are important in improving PCR product yield and in avoiding the formation of spurious products, and the usage of alternate buffer components or polymerase enzymes can help with amplification of long or otherwise problematic regions of DNA.

Television

Television (often abbreviated to TV, T.V., or more recently, tv) is a widely used telecommunication system for broadcasting and receiving moving pictures and sound over a distance from all around the world. The term may also be used to refer specifically to a television set, programming or television transmission. The word is derived from mixed Latin and Greek roots, meaning "far sight": far, and Latin vision, sight.

Since it first became commercially available from the late 1930s, the television set has become a common household communications device in homes and institutions, particularly in the First World, as a source of entertainment and news. Since the 1970s, video recordings on VCR tapes and later, digital playback systems such as DVDs, have enabled the television to be used to view recorded movies and other programs.

Natural nuclear reactors

The natural nuclear reactors formed when a uranium-rich mineral deposit became inundated with groundwater that acted as a neutron moderator, and a strong chain reaction took place. The water moderator would boil away as the reaction increased, slowing it back down again and preventing a meltdown. The fission reaction was sustained for hundreds of thousands of years.

These natural reactors are extensively studied by scientists interested in geologic radioactive waste disposal. They offer a case study of how radioactive isotopes migrate through the earth's crust. This is a significant area of controversy as opponents of geologic waste disposal fear that isotopes from stored waste could end up in water supplies or be carried into the environment.

Multithreading in Java

Java provides built-in support for multithreaded programming. A multithreaded program will have 2 or more parts that can run concurrently. Each part of such a program in java is called a thread, and each thread defines a separate path of execution. It is a specialized form of multitasking. There are two distinct types of multitasking namely Process-based and Thread-based.

A short note on typically groundwater

Typically groundwater is consider of as liquid water flowing through shallow aquifers, however technically it can as well include soil moisture, permafrost (frozen soil), motionless water in extremely low permeability bedrock, and deep geothermal or oil formation water. Groundwater is assumed to give lubrication and buoyancy which let thrust faults to move. Almost any point in the Earth's subsurface has water in it; to some degree (it can be very dry or mixed with other fluids). Groundwater is not restricted or confined only to the Earth, either; subsurface water on Mars is considered to have given rise to some of the landforms.

What do you mean by Collective and non-human intelligence?

Some thinkers have discovered the idea of collective intelligence, arising from the bringing together of many people. A battleship, for example, cannot be operated by a single person's knowledge, actions and intelligence; it takes an organized and interacting crew. In the same way, the interesting behaviors of a bee colony are not displayed in the intelligence and the actions of any single bee, but somewhat understandable in the behavior of the hive. These ideas are travel around as a basis for human thought, with applications for the artificial intelligence (AI), by the MIT AI pioneers Norbert Wiener and the Marvin Minsky. The Artificial intelligence (AI) has emerged from the Computer science as a specialty which looks for to make computers act in ever more intelligent ways, and gives insights into human thought processes.

When allowing for animal intelligence, a more common definition of intelligence might be applied: the "ability to get used to efficiently to the environment, both by making a change in oneself or by changing the environment or by finding a new one”. Numerous people have as well speculated about the possibility of extraterrestrial intelligence.

A short note on Snake River

The Snake River is the river, in the western part of the United States. The Snake River is 1,038 miles (1,670 km) in total length, and is the Columbia River's most important tributary. The Lewis and Clark expedition (1803-6) was the first main U.S. exploration of the river, and the Snake was one time known as the Lewis River.

The Snake River's many hydroelectric power plants are a most important starting place of electricity in the region. Its watershed offers irrigation for various projects, as well as the Minidoka, Boise, Palisades, and the Owyhee projects by the U.S. Bureau of Reclamation, with a variety of private projects for example, at Twin Falls. On the other hand, these dams have as well had an adverse environmental effect on wildlife, most remarkably on wild salmon migrations.

The Snake runs through numerous gorges, with one of the deepest in the world, Hells Canyon, with a maximum depth of 7,900 feet (2,410 m). The name "Snake" probably derived from an S-shaped (snake) sign which the Shoshone Indians complete with their hands to mimic swimming salmon.

What do you mean by Water injection pumps?

The high force or pressure, high flow water injection pumps are positioned near to the de-oxygenation tower and Boosting Pumps. They fill the bottom of the tank with the filtered water to push the oil in the direction of the wells like a piston. The outcome of the injection is not quick, it requires time. The Water Injection is used to stop low pressure in the reservoir. The water restores the oil which has been taken, keeping the production rate and the force the same over the long term. For instance, if the Water Injection is stopped for a day the manufacture rate is not changed, dissimilar with gas lifts. The Gas lifts are the opposite; if the injection is broken up the production will stop instantaneously, for the reason that gas lifts have only a short term effect.

What do mean by Nomenclature and roads?

The nomenclature used for various types of highways like freeway, expressway, motorway and autobahn; differ between countries or even regions within a country. In several places a highway is a particular type of major road that is distinct from freeway or expressway; in other places the terms could overlap. In law highway may indicate any public road or canal. But, in some countries, the word highway is not generally used at all.

A road is a strip of land, paved, smoothed, or otherwise organized to let easy travel, connecting two or more destinations. Few roads are streets, mainly in urban areas. In the milieu of railways (railroads in American English), a road is a single pathway, which may be part of a multi-track system or could be an isolated line. In the milieu of sea transport, a road is an anchorage to travel.

A general view on Supercomputer

The supercomputer is the fastest type of computer. Supercomputers are very costly and are employed for specific applications that require immense amounts of mathematical calculations. For instance, weather forecasting necessitates a supercomputer. Other uses of supercomputers contain animated graphics, nuclear energy research, fluid dynamic calculations, and petroleum exploration.

The chief differentiation between a supercomputer and a mainframe is that a supercomputer channels all its power into executing some programs as fast as possible, whereas a mainframe uses its power to carry out many programs concurrently.

Supercomputers are used for exceedingly calculation-intensive tasks like problems connecting weather forecasting, quantum mechanical physics, climate research (together with research into global warming), molecular modeling (computing the structures and properties of chemical compounds, polymers, biological macromolecules, and crystals), physical simulations (like simulation of airplanes in wind tunnels, imitation of the detonation of nuclear weapons, and research into nuclear fusion), cryptanalysis, and the like.

Supercomputers using tradition CPUs custom gained their speed over conventional computers through the employ of ground-breaking designs that allow them to carry out many tasks in parallel, as well as complex detail engineering. They are inclined to be specialized for definite types of computation, generally arithmetical calculations, and carry out poorly at more general computing tasks. Their memory hierarchy is very cautiously designed to make sure the processor is kept fed with data and instructions at all times— in actual fact, much of the performance difference between slower computers and because of the memory hierarchy of Supercomputers the I/O systems tend to be designed to support high bandwidth, with latency less of an issue, because it is not used for transaction processing.

The real Existence of God

There are numerous arguments for and against the reality and existence of God have been proposed and cast off by philosophers, theologians, and added thinkers. In philosophical terminology, such arguments concern schools of thought on the epistemology of the ontology of God.

There are lots of philosophical issues concerning the existence of God. Some definitions of God are so unclear that it is certain that something exists that meets the definition; while other definitions are it seems that self-contradictory. Arguments for the existence of God characteristically include empirical, inductive, metaphysical, and subjective types. Arguments next to the existence of God normally contain empirical, deductive, and inductive types. Conclusions reached contain: "God exists and this can be confirmed"; "God exists, but this cannot be confirmed or disproven" (theism in both cases); "God does not survive" (strong atheism); "God roughly certainly does not exist" (de facto atheism); and "no one knows whether God exists" (agnosticism). There are many variations on these positions.

A current argument for the existence of God is called clever or intelligent design, which asserts that "certain features of the world and of living things are best explained by a clever cause, not an undirected procedure for instance natural selection". It is a modern form of the traditional argument from design, modified to keep away from specifying the nature or identity of the designer. Its main proponents, all of whom are connected with the Discovery Institute, just believe the designer to be the Abrahamic God.

A Beautiful Island

For several people, the land in America is the beautiful place in this world. But as a little adult I have already left the country to find many opportunity sights beyond the land of the United States. To me, the largest beautiful place I have ever been was the island of Jamaica. It is simple for me to find harmony and beauty on this island.
The first thing that hit me like a massage of aroma as I stepped off the aircraft was the sweet wet air of this tropical island. The fruit, flowers, and over all ordinary environment is enough to make me never want to leave. I gather all of this, and I haven’t even left the airport yet.

The local yellow cab takes me crossways the island. Overwhelmed by beauty far and wide I find myself out of breath. Not far into my turn I encounter a busy street buzzing with stimulation and variety.

The computer

A computer is a machine for manipulate data according to a list of commands known as a program. Computers are tremendously adaptable. In fact, they are universal information-processing machines. According to the Church–Turing theory, a computer with a positive minimum entrance capability is in principle capable of performing the responsibilities of any other computer. Therefore, computers with capability ranging from those of a personal digital supporter to a supercomputer may all achieve the same tasks, as long as time and memory capacity are not consideration. Therefore, the same computer design may be modified for tasks ranging from doling out company payrolls to controlling unmanned spaceflights. Due to technical progression, modern electronic computers are exponentially more capable than those of preceding generations. Computers take plentiful physical forms. Early electronic computers were the size of a large room, while whole modern embedded computers may be lesser than a deck of playing cards. Even today, huge computing conveniences still exist for focused scientific computation and for the transaction processing necessities of large organizations. Smaller computers designed for personage use are called personal computers. Along with its convenient equivalent, the laptop computer, the personal computer is the ubiquitous in order processing and communication tool, and is typically what is meant by "a computer". However, the most general form of computer in use today is the embedded computer. Embedded computers are usually comparatively simple and physically small computers used to control one more device. They may control equipment from fighter aircraft to industrial robots to digital cameras. in the beginning, the term "computer" referred to a person who performed numerical calculations, frequently with the aid of a mechanical calculating device or analog computer. In 1801, Joseph Marie Jacquard made an improvement to the presented loom designs that used a series of punched paper cards as a program to weave involved patterns. The resulting Jacquard loom is not considered a true computer but it was an essential step in the growth of modern digital computers.

Charles Babbage was the first to conceptualize and design a completely programmable computer as early as 1820, In 1801, Joseph Marie Jacquard made an improvement to the presented loom designs that used a series of punched paper cards as a program to weave involved patterns. The resulting Jacquard loom is not considered a true computer but it was an essential step in the growth of modern digital computers.

But due to a combination of the restrictions of the technology of the time, limited finance, and an incapability to resist tinkering with his design, the device was never really constructed in his lifetime. By the end of the 19th century a number of technologies that would later prove helpful in computing had appeared, out such as the punch card and the vacuum tube, and large-scale automated data giving using punch cards was performed by tabulating equipment designed by Hermann Hollerith.During the first half of the 20th century, many technical computing wants were met by increasingly difficult special-purpose analog computers, which used a direct mechanical or electrical model of the problem as a base for subtraction (they became ever more rare after the development of the programmable digital computer). Sequence of gradually more powerful and stretchy computing devices were construct in the 1930s and 1940s.

A Little Cloud

He wrote the story A Little Cloud the story was print in 1905. A Little Cloud takes position in Dublin. This is recognized to be a dirty town. Little Chandler is a thirty-two year old marital man with one son who is not fairly one year old in the story. He is called little Chandler because of his look. He is somewhat under height, which is he, under one hundred and eighty-five centimeters. He has little white hands, babyish teeth and excellent nail care. Little Chandler has a delicate frame, silken hair and body hair; he has a quiet voice and superior manners.

Little Chandler is a sober man, meaning he is sparing in consumption and drinking. Little Chandler blushes very simply at more or less anything. He appears to have a good-looking life; he moving parts at the Kings Inn at a desk. He likes to read poetry and sometime would like to write it. Little Chandler has never been in a great deal of problem before in his life. He frequently thinks about his friend Ignatius Gallagher while at job, and how he has become a shining man in the Press. Little Chandler regularly thinks of his life, which makes him sad.

MS-DOS

MS-DOS is an operating system commercialized by Microsoft. It was the commonly used member of the DOS family of operating systems and was the dominant operating system for the PC well-matched platform during the 1980s. It has gradually been replaced on consumer desktop computers by a variety of generations of the Windows operating system.

Microscope

A microscope is a device for viewing objects that are too small to be seen by the naked or unaided eye. The science of investigating small objects using such an instrument is called microscopy. The word microscopic means minute or very small, not visible with the eye unless aided by a microscope. The microscopes used in schools and homes sketch their history back almost 400 years.

Valencia orange

The Valencia or Murcia orange is one of the sweet oranges used for juice mining. It is a late-season fruit, and therefore a popular variety when the navel oranges are out of season. For this reason, the orange was chosen to be the official mascot of the 1982 FIFA World Cup, which was held in Spain. The mascot was called "Naranjito" ("little orange"), and wore the colors of the Spanish soccer team uniform.

Sattriya

Sattriya, or Sattriya Nritya, is one among eight principal classical Indian dance civilizations. The other seven are Bharatanatyam, Kathakali, Mohini Attam, Kuchipudi, Odissi, Kathak, and Manipuri. Whereas some of the other traditions were revitalized in the recent pasts, Sattriya dance has been a living tradition since it its creation by the Srimanta Sankardeva in the 15th century in Assam.

Rolling stock

Rolling stock is the communal term that describes all the vehicles which move on a railway. It usually includes both powered and uncovered vehicles, for example locomotives, railroad cars, coaches and wagons. The term is sometimes used to refer only to non-powered vehicles, specifically excluding locomotives.The term contrasts with fixed stock, which is a communal term for the track, signals, stations and buildings etc. necessary to operate a railway. However this latter term is now much less widely used than rolling stock. Fixed stock is also called infrastructure.

Sunglasses

Sunglasses may be made with either prescription or non-prescription (i.e. Plano) lenses that are darkened to offer protection against bright visible light. Good quality sunglasses should also protect against ultraviolet light. Due to changes in the atmosphere, ultraviolet levels are much elevated than in the past and ultraviolet protection for eyes and skin is even more important. It is possible to have lenses that seem very dark and yet offer little ultraviolet protection. Sunglasses fluctuate greatly and many offer more style than protection.

Flower anatomy

Flowering plants are heterosporangiate and the pollen and ovules are produced in different organs, but these are together in a bisporangiate strobilus that is the typical flower. A flower is regarded as a modified stem with shortened internodes and behavior, at its nodes, structures that may be highly adapted leaves. In essence, a flower structure forms on a modified shoot or axis with an apical moisten that does not grow constantly. The stem is called a pedicel, the end of which is the tours or container.

Marketing

Marketing is one of the most significant functions in business. It is the regulation required to understand customers' needs and the benefits they seek. Academia does not have one commonly agreed upon description. Even after a better part of a century the dispute continues. In a nutshell it consists of the social and managerial processes by which goods or services and value are exchanged in order to fulfill the needs and wants of individuals or groups. Although many people appear to think that "marketing" and "advertising" are synonymous, they are not. Advertising is simply one of the lots of processes that together constitute marketing.

Web proxy

Proxies that hub on WWW traffic are called web proxies. Many web proxies try to block offensive web content. Other web proxies reformat web pages for an exact purpose or audience (e.g., cell phones and PDAs or persons with disabilities). Network operators can also set up proxies to intercept computer viruses and other hostile content served from remote web pages.

Many organizations — including schools, corporations, and countries — use proxy servers to implement acceptable network use policies or to provide security, anti-malware and/or caching services. A traditional web proxy is not translucent to the client application, which must be configured to use the proxy (manually or with a configuration script). In some cases, where substitute means of connection to the Internet are available, the user may be able to avoid policy control by simply resetting the client configuration and bypassing the proxy. Furthermore administration of browser configuration can be a load for network administrators.

ARM

The ARM architecture (Advanced RISC Machine or Acorn RISC Machine) is a 32-bit RISC processor architecture developed by ARM Limited that is widely used in a number of embedded designs. Due to their power saving features, ARM CPUs are dominant in the mobile electronics market, where low power consumption is a critical design goal.

Today, the ARM family accounts for over 75% of all 32-bit embedded CPUs, making it one of the most prolific 32-bit architectures in the world. ARM CPUs are found in all corners of consumer electronics, from portable devices to computer peripherals. Important branches in this family include Marvell's XScale and the Texas Instruments OMAP series.

Ice

Ice is the name given to any one of the 14 known solid phases of water. Though in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases. It is a crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also deposit from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers. It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

Neem cake

Neem cake natural manure is the by-product obtained in the process of cold pressing of Neem fruits and kernels, and the solvent removal process for neem oil cake. It is a potential source of organic manure under the Bureau of India Standards, Neem has established considerable potential as a fertilizer. For this purpose, neem cake and neem leaves are particularly promising. Puri , in his book on neem has given details about neem seed cake as manure and nitrification inhibitor. The author has described that after processing neem cake can be used for partial replacement of poultry and cattle feed.

People

People are a group of humans, either with not mentioned traits, or specific characteristics (e.g. the people of Spain or the people of the Plains).The term people is often used in English as the suppletive plural of person. However, the word persons is sometimes used in place of people, particularly when it would be ambiguous with its collective sense (e.g. missing persons instead of missing people). The term people can together refer to all humans or it can be used to identify the citizens of a nation, or members of a tribe, ethnic, or religious group. People of color is a phrase used to describe people with skin color darker than that of white people.

Electromagnetic hypersensitivity syndrome

Some users of mobile handsets have reported feeling several unspecific symptoms during and after its use, such as burning and tingling feelings in the skin of the head and extremities, fatigue, sleep disturbances, dizziness, loss of mental attention, reaction times and memory retentiveness, headaches, malaise, tachycardia and disturbances of the digestive system. Some researchers, implying a causal relationship, have named this syndrome as a new diagnostic entity, EHS or ES (electro sensitivity). The World Health Organization prefers to name it “idiopathic environmental intolerance", in order to avoid the implication of causation.

Chess strategy

Chess strategy is concerned with the evaluation of chess positions and with setting up goals and long-term tactics for upcoming play. During the evaluation, a player must take into account the value of pieces on the board, pawn structure, king safety, positioning, and control of key squares and groups of squares.

The most basic is to count the total value of pieces on both sides. The point values used for this purpose are based on familiarity. Usually pawns are considered worth one point, knights and bishops three points each, rooks five points, and queens nine points. The fighting value of the king in the endgame is equivalent to four points. These basic values are modified by other factors such as position of the piece, coordination between pieces or type of position.

Another important factor in the evaluation of chess positions is the pawn structure or pawn skeleton. Since pawns are the most immobile of the chess pieces, the pawn structure is moderately static and largely determines the calculated nature of the position. Weaknesses in the pawn structure, such as isolated, doubled or backward pawns and holes, once created, are usually permanent. Care must therefore be taken to avoid them unless they are remunerated by another valuable asset, such as the chance to develop an attack.

American carrom

American carrom is an alternative on carrom derived in America by missionaries to the East, around 1890. Believing that the game required restructuring for Western tastes, a Sunday school teacher named Henry Haskell altered the game. Much of the game is the same, but the striker's weight is reduced and the carrom men are smaller. Generally, instead of disks of solid wood, ivory, or acrylic, carrom men are rings, originally of wood but today commercially made of light plastic. In addition, as an alternative to using the fingers to flick the striker,American carrom uses miniature cue sticks. American carrom boards also have pockets built into the corners, rather than circular holes in the board, to make pocketing easier. While traditionally made boards vary widely, current commercially-produced American carrom boards are 28 inches square, are printed with checkerboard and backgammon patterns, among others, and are sold with checkers, chess pieces, skittles, etc., to allow other games to be played on the same board. Often, these boards are also built to play crokinole.

Sound card

A sound card is a computer development card that can input and output sound under control of computer programs. Typical uses of sound cards include given that the audio component for multimedia applications such as music composition, editing video or audio, presentation/education, and entertainment. Many computers have sound capabilities built in, while others require these expansion cards if audio capability is desired.

Applied Micro Circuits Corporation

Applied Micro Circuits Corporation is a fables semiconductor company scheming network and embedded Power Architecture, optical transport and storage solutions. They bought assets, IP and engineers concerning the PowerPC 400 microprocessors from IBM in 2004 for $227 million and they now market the processors under their own name. The deal also included access to IBM's SoC design methodology and advanced CMOS process technology.

3ware is a producer of RAID controllers and storage products. Founded as an self-governing company in 1997, it was acquired by AMCC in April 2004.This division has usually been focused on SATA and PATA RAID devices. They were one of the pioneers in implementing "multi-lane" cabling for RAID systems which greatly reduced cable difficulty in systems with many hard drives.

Police dog

A police dog is a dog that is taught specially to assist police and similar law-enforcement personnel with their work. They are also known in the United States as police K9s. The term is occasionally used in the common parlance of several countries to refer to any German Shepherd Dog because of the long history of the use of the German Shepherd by the police and military; in some nations German Shepherds are the only dogs used by those forces. In the post-industrial era German Shepherds have often been depicted as police dogs in television, movies and police dog memorials. This breed is often still used, as are a few other breeds.

Historical and Stylistic Clock face

Before progress the late 15th century, a fixed hand indicated the hour by pointing to revolving numbers. Minute hands only came into use in the late 17th century after the creation of the pendulum allowable for amplified precision in time telling. Until the last quarter of the 17th century hour markings were imprinted into metal faces and the recesses filled with black wax. Subsequently, higher contrast and enhanced readability was achieved with white enamel plaques painted with black numbers. Initially, the numbers were printed on small, individual plaques mounted on a brass substructure. This was not a stylistic decision; rather enamel production technology had not yet achieved the ability to create large pieces of enamel. The "13 piece face" was an early attempt to create an entirely white enamel face. As the name suggests, it was composed of 13 enamel plaques: 12 numbered wedges fitted around a circle. The first single portion enamel faces, not unlike those in production today, began to appear c. 1735.

Bluetooth

Bluetooth is an industrial requirement for wireless personal area networks (PANs). Bluetooth provides a way to connect and swap information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are licensed and developed by the Bluetooth Special Interest Group.

Bluetooth is a radio standard and communications protocol mostly designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. The devices use a radio communications system, so they do not have to be in line of view of each other, and can even be in other rooms, as long as the conservative transmission is powerful enough.

Ocean

Ocean covers almost three quarters of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep.
This global, consistent body of salt water, called the World Ocean, is divided by the continents and archipelagos into the following four bodies, from the largest to the smallest: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean, and, according to some authorities such as International Hydrographic Organization, a fifth ocean, the Southern Ocean.
Some geographers and some governments but not the US, recognizes the IHO as defining official water body names and boundaries. The IHO officially sanctioned the Southern Ocean name only in 2000, but its definition by a line of latitude has left its acceptance as a fifth ocean open to question. The National Geographic Society and some other leading geographers and cartographers continue to use "South Pacific", "South Atlantic", and "Indian" Ocean for the waters around Antarctica. A few Oceanographers recognize only four oceans also, treating the Arctic Ocean as a part of the Atlantic Ocean.

Radio

Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of light.Radio waves.Radio waves are a form of electromagnetic radiation, formed whenever a charged object accelerates by a frequency that lies in the radio frequency (RF) portion of the electromagnetic spectrum. This is the variety from a few tens of hertz to a few hundred gigahertz.Electromagnetic radio spectrum Other types of electromagnetic radiation, with frequencies above the RF range are infrared, visible light, ultraviolet, X-rays and gamma rays. Since the energy of an individual photon of radio frequency is too low to remove an electron from an atom, radio waves are classified as non-ionizing radiation.Radio transmission diagram and electromagnetic waves.Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space equally well, and does not need a medium of transport induces an alternating current and voltage in the conductor. This can be transformed into audio or other signals that carry information. Although the word 'radio' is used to explain this phenomenon, the transmissions which we know as television, radio, radar, and cell phone are all classed as radio frequency emissions.

Electric chair

The electric chair was a mechanism commonly used for execution of convicted criminals during the 20th century in the USA. It was first used in the not on time 19th century. It was used by more than 25 states throughout the 20th century, acquiring nicknames such as Sizzlin' Sally, Old Smokey, Old Sparky, Yellow Mama, and Gruesome Gertie. To be put to death in an electric chair is colloquially known as "riding the lightning." Its continued use in the 21st century seems to be quickly on the way out. The electric chair was also used, for a time, in the Philippines.

History

The first practical electric chair was made-up by Harold P. Brown. Brown was an employee of Thomas Edison's, hired for the function of researching electrocution and for the growth of the electric chair. Since Brown worked for Edison, and Edison promoted Brown's work, the development of the electric chair is often incorrectly credited to Edison himself. Brown's design was based on Alternating Current, which was then just emerging as the rival to Edison's less transport-efficient Direct Current, which was further along in commercial progress. The decision to use AC was wholly driven by Edison's attempt to claim that AC was more lethal than DC.

New York State in 1886 recognized a committee to determine a new, more humane system of implementation to replace hanging. Neither Edison nor Westinghouse wanted their electrical system to be selected because they feared that consumers would not want in their homes the same type of electricity used to kill criminals.

In order to prove that AC electricity was superior for executions, Brown and Edison killed many animals, including a circus elephant, while testing out their prototypes. They also held executions of animals for the press in order to ensure that AC current was connected with electrocution. It was at these events that the term "electrocution" was coined. Most of their experiments were conducted at Edison's West Orange, New Jersey, laboratory in 1888.

Sarus Crane

The Sarus Crane is a occupant breeding bird in northern India, Nepal, Southeast Asia and Queensland, Australia. It used to be found on occasion in pakistan, but has not been found sience the late 1980's. It is the world's tallest flying bird.

This is an extremely big crane, 156cm in length, which is found in freshwater marshes and plains. It nests on the ground laying two to three eggs in a large nest. Unlike many cranes that make long migrations the sarus crane does not, meaning it cans expent the energy to raise both chicks. Both the male and female take turns sitting on the nest, and the male is the main guardian.

Adults are grey with a nude red head and white crown and a long dark sharp bill. In flight, the long neck is kept in a straight line, unlike herons, and the black wing tips can be seen; their long red or pink legs trail at the back them.

Sexes are similar, but little birds are duller and browner. The Indian, Southeast Asian and Australian subspecies is different mainly in plumage shade. There are some slight size differences, but on average the male is larger then the female, and the birds are six feet tall with an eight foot wingspan.

These sociable birds forage while walking in shallow water or in fields, sometimes inquisitive with their long bills. They are omnivorous, eating insects, aquatic plants and animals, crustaceans, seeds and berries, small vertebrates, and invertebrates.

The Indian population is about 10,000 birds, and the Australian population of 5,000 birds may be rising, but the Southeast Asian subspecies has been decimated by war and home obliteration.
In Australia, the Sarus can with no trouble be incorrect for the Brolga. The Brolga has a more extensive distribution across the country, and its red coloring is limited to the head. However the brogla and sarus are genetically completely different and the natives of astrillia were aware that they were two different types of bird’s referring to the sarus as the brogla who’s curved in its head in blood.

Delta Air Lines

Delta Air is a major U.S. airline headquartered in Atlanta, Georgia, operating a large domestic and international network that spans North America, South America, Europe, Asia, and the Caribbean.

Delta operates hubs at Atlanta, Cincinnati, New York-JFK, and Salt Lake City. Delta also has great operations in many other cities, including Boston, Columbus, Fort Lauderdale, Los Angeles, New York-LaGuardia, Orlando, and Washington-Reagan. Delta is also the foremost hauler in Florida. Its key worldwide gateways are Atlanta, Cincinnati, and New York-JFK.

In terms of passengers approved, Delta is the second-largest airline in the world. In terms of total operating revenues, Delta is the fourth-largest airline in the world As of September 1, 2005, Delta served 178 domestic cities in 46 states, Puerto Rico, and the U.S. Virgin Islands, as well as 71 international cities, including 10 future ones, in 45 countries.

Early history

Delta timetable from 1934
Delta Boeing 747, operated by Pan Am, at London Heathrow Airport in May 1974.The corporation has its roots in Huff Daland Dusters, which was founded in 1924 in Macon, Georgia by more than a few partners with Collett E. Woolman becoming the world's first aerial crop dusting company. Huff Daland moved to Monroe, Louisiana the following year. In 1928, Huff Daland Dusters was purchased by C.E. Woolman and renamed Delta Air military after the Mississippi Delta, where its route joined Dallas, Texas to Jackson, Mississippi, via Shreveport, Louisiana and Monroe. By 1934, Delta Air began mail service from Charleston to Fort Worth, including Atlanta, Augusta and other stops in Georgia.

In 1941, Delta enthused its headquarters from Monroe to Atlanta, Georgia, to center itself along its new way network that joined Chicago and New Orleans to Florida and Ohio which would later become a Delta hub. In the 1950s, Delta began flights from New Orleans to the Caribbean and Venezuela, becoming the number 2 U.S. carrier in the region after Pan Am and Braniff. On May 1, 1953, Delta combined with Chicago and Southern to enlarge routes in Midwest. In 1955 Delta introduced the "hub and spoke system" where flights are running scared to a central point then sent out to other cities. By the early 1960s, Delta's route network extended to the West Coast, and Dallas was emerging as its second hub city.

Movie camera

The movie camera is a type of photographic camera which takes a quick sequence of photographs on film; once developed this film can be projected as a action picture. In contrast to a still camera which captures a single picture at a time, the movie camera takes a sequence of images, each called a Frame. This is accomplished through an constant mechanism. The frames are later played back in a movie projector at a specific speed, called the "frame rate" to give the illusion of motion. Our eyes and brain merge the separate pictures together to create the illusion, a phenomenon called the "persistence of vision".
Most of the ocular and mechanical rudiments of a movie camera are present in the movie projector. The camera will not have an illumination source and will keep its film stock in a light-tight enclosure. A camera will also have revelation control via an iris aperture located on the lens. Otherwise, the requirements for film tensioning, take-up, alternating motion, loops, and rack positioning are almost identical.

Cellular

A cellular network is a radio network made up of a number of radio cells (or just cells) each served by a fixed transmitter, normally known as a (base station). These cells are used to cover dissimilar areas in order to provide radio coverage over a wider area than the area of one cell. Cellular networks are naturally asymmetric with a set of fixed main transceivers each serving a cell and a set of distributed transceivers which provide services to the network's users.
Cellular networks offer a number of advantages over alternative solutions,
increased capacity
reduced power usage
better coverage
A good (and simple) example of a cellular system is an old taxi driver's radio system where a city will have some transmitters based around a city. We'll use that as an example and assume that each transmitter is handled independently by a different operator.

View camera

The view camera is a type of camera with a very long history, but they are still used today by professional and amateur photographers who want full control of their images. The view camera is essentially a light-tight assembly comprised of a flexible mid-section, or bellows, attached to a device that holds a film sheet, photo plate or digital imager at one end (the rear standard) and a similar one that holds the lens at the other end (the front standard). The front and rear standards are not fixed relative to each other (unlike most cameras). Movement of the front and rear standards allows the photographer to move the lens and film plane separately for precise control of the image's focus, depth of field and perspective.

Eye color

Eye color is a polygenic trait and is determined mainly by the amount and type of pigments present in the eye's iris. Humans and animals have many phenotypic variations in eye color. In humans, these variations in color are credited to varying ratios of eumelanin produced by melanocytes in the iris.The brightly colored eyes of many bird species are mostly determined by other pigments, such as pteridines, purines, and carotenoids.
Three main elements within the iris add to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma.In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin.Color variations among different irises are normally attributed to the melanin content within the iris stroma.The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium.

Coma

In medicine, a coma (from the Greek koma, meaning deep sleep) is a profound state of unconsciousness. A comatose patient cannot be awakened, fails to respond in general to pain or light, does not contain sleep-wake cycles, and does not take voluntary actions. Coma may result from a variety of conditions, including intoxication, metabolic abnormalities, central nervous system diseases, acute neurologic injuries such as stroke, and hypoxia. It may also be intentionally induced by pharmaceutical agents in order to preserve higher brain function following another form of brain trauma.

Distinctive phases of coma
Within coma itself, there are some categories that describe the severity of impairment. Contrary to popular belief, a patient in a comatose state does not always lay still and quiet. They may talk, walk, and perform other functions that may occasionally appear to be conscious acts, yet are not.
Two scales of measurement regularly used in TBI diagnosis to determine the phase of coma are the Glasgow Coma Scale and the Ranchos Los Amigos Scale. The GCS is a simple 15-point scale used by medical professionals to assess severity of neurologic trauma, and establish a prognosis. The RLAS is a more complex scale that describes up to eight separate levels of coma, and is often used in the first few weeks or months of coma while the patient is under nearer observation, and when shifts between levels are more frequent.

Language school

A language school is a place of education where one can study a foreign language. In most cases, classes at a language school are geared towards, but not limited to, talkative competence in a foreign language. Language learning in such schools usually supplements formal education or experience in a foreign language.
Students vary generally by, among other factors, age, educational background and work experience, as well as language ability. Teachers are likely to possess native fluency or acquired comptence in their target languages; formal qualifications to become a language teacher, however, vary by school, region or country.

Monkey

A monkey is a member of either of two of the three groupings of simian primates. These three groupings are the New World monkeys, the Old World monkeys, and the apes. The New World monkeys are classified within the parvorder Platyrrhini, whereas the Old World monkeys (superfamily Cercopithecoidea) form part of the parvorder Catarrhini, which also includes the apes. Thus, methodically speaking, monkeys do not form a "natural group", in that the Old World monkeys are in fact more closely related to the apes than they are to the New World species. There are 264 known extant species of monkey. Because of their similarity to monkeys, apes such as chimpanzees and gibbons are often called monkeys in informal usage, though biologists don't consider them to be monkeys. Conversely, due to its size (up to 1 metre) the Mandrill is often thought to be an ape, but it is actually an Old World monkey. Also, a few monkey species have the word "ape" in their common name. Because they are not a single coherent group, monkeys do not have any particular traits that they all share and are not shared with the remaining group of simians, the apes.

Manhattan

Manhattan refers to both the Island of Manhattan and encompasses most of the Borough of Manhattan, one of the five boroughs of New York City. The viable, financial, and cultural center of the city, Manhattan has many famous landmarks, tourist attractions, museums and universities. It is also home to the control center of the United Nations and the seat of city government.The borough of Manhattan is coterminous with New York County, which is also the most densely populated county in the United States. Postal addresses within the borough are typically chosen as "New York, NY."Manhattan has the biggest central business district in the United States and is the site of most of the city's corporate headquarters and the New York Stock Exchange. Although its population is third biggest of the five boroughs, after Brooklyn and Queens, and it is geographically the smallest, Manhattan is the borough that many visitors most personally associate with New York City.

Heart cancer

Heart cancer is an very rare form of cancer of the heart. Heart cancer is separated into primary tumors of the heart and secondary tumors of the heart. Most heart cancers are benign of myxomas, fibromas, rhabdomyomas and hamartomas, although malignant sarcomas (such as angiosarcoma or cardiac sarcoma) have been well-known to occur. In a learning of 12,487 autopsies performed in Hong Kong seven cardiac tumors were found, most of which were benign. However, cancer can also reach to heart from other parts of the body. In addition the heart can be affected by handling for cancer in other parts of the body.

Cloud

The color of a cloud tells much about what is going on inside the cloud. Clouds form when comparatively warm air containing water vapor is lighter than its surrounding air and this causes it to rise. As it rises it cools and the vapor condenses out of the air as micro-droplets. These tiny particles of water are relatively densely packed, and sunlight cannot penetrate far into the cloud before it is reflected out, giving a cloud its characteristic white color. If the cloud is sufficiently large, and the droplets within are spaced far enough apart, it may be that a proportion of the light which enters the cloud is not reflected back out before it is absorbed This process of reflection/absorption is what leads to the range of cloud color from white through grey through black. For the same reason, the undersides of large clouds and heavy overcasts appear various degrees of grey; little light is being reflected or transmitted back to the observer.Other colors occur naturally in clouds. Bluish-grey is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light's visible wavelengths, while red and yellow are at the long end. The short rays are more simply scattered by water droplets, and the long rays are more likely to be absorbed. The bluish color is evidence that such scattering is being produced by rain-sized droplets in the cloud.A more ominous color is the one seen commonly by severe weather observers. A greenish tinge to a cloud is produced when sunlight is scattered by ice. A cumulonimbus cloud which shows green is a pretty sure sign of imminent heavy rain, hail, strong winds and possible tornados. Yellowish clouds are rare, but may occur in the late spring throughout early fall months during forest fire season. The yellow color is due to the presence of smoke. Red, orange and pink clouds occur almost wholly at sunrise/sunset and are the result of the scattering of sunlight by the atmosphere itself. The clouds themselves are not that color; they are merely reflecting the long rays of sunlight which are predominant at those hours. The effect is much the same as if one were to shine a red spotlight on a white sheet. In combination with large, mature thunderheads, this can produce blood-red clouds.

Ganesha drinking milk again

NEW DELHI: In a re-run of the September 1995 frenzy when Ganesha statues were said to be drinking milk offered to them, devotees apparently thronged temples on Sunday night, making alike claims. This time, nevertheless, all idols were reported to be drinking milk.
This followed some reports received from additional parts of the country, particularly UP, earlier in the day. Shiv Mandir in Uttam Nagar and Shri Ram temple on Aruna Asaf Ali Marg in New Delhi witnessed a huge rush.
Said a Ram temple priest, "People observed that Ganesha is drinking milk around 8 pm, after which the word spread and thousands thronged the temple to try it out. Lord Ganesha drank milk from all. The crowd remained till around 11 pm."
Rationalists have explained the scientific cause behind this phenomenon, including surface tension, but faith and superstition always hit back. Said a devotee, "It was amazing.”

Journalism Basics

Journalism is a concrete, professionally oriented major that involves gathering, interpreting, distilling, and other reporting information to the general audiences through a variety of media means. Journalism majors learn about every possible kind of Journalism (including magazine, newspaper, online journalism, photojournalism, broadcast journalism, and public relations).
That's not all, though. In addition to dedicated training in writing, editing, and reporting, Journalism wants a working knowledge of history, culture, and current events. You'll more than likely be required to take up a broad range of courses that runs the range from statistics to the hard sciences to economics to history. There would also be a lot of haughty talk about professional ethics and civic responsibility too - and you'll be tested on it. To top it all off, you'll perhaps work on the university newspaper or radio station, or possibly complete an internship with a magazine or a mass media conglomerate.
