It has dangerous effects on the environment and on structures. It is mostly caused by emissions due to human activity of sulfur and nitrogen compounds which respond in the atmosphere to produce acids. In recent years, many governments have introduced laws to lessen these emissions. Both lower pH and higher aluminum concentration in the surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals. At pHs lower than 5 most of the fish eggs would not hatch and lower pHs can kill adult fish. As lakes become more acidic biodiversity is also reduced. Soil biology can be critically damaged by acid rain. Some tropical microbes can quickly consume acids but other microbes are incapable to tolerate low pHs and are killed. The enzymes of these microbes are denatured by the acid. The hydronium ions of acid rain also mobilize toxins and filter away essential nutrients and minerals

Stonewalls and towers of the Meenakshi temple is rising out of the teeming streets of Madurais city center. From her rambling maze-like palace, the Goddess Meenakshi presides here. It is said that her image (all three and a half feet tucked into the ancient and dark sanctuary, which is lit by a steady glow from an oil lamp) is carved out of a single emerald.This whole magnificent temple complex sprawls over an area of 6 hectares. It also has 12 gopurams, ranging in height from 45 to 50 m, which is the tallest being the southern one. The southern gateway is very beautifully proportioned and is nine stories high.

It is most often defined as a woody plant that has secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance.Trees are an important component of the natural landscape because of their prevention of erosion and the provision of a specific weather-sheltered ecosystem in and under their foliage. Trees have also been found to play an important role in producing oxygen and reducing carbon dioxide in the atmosphere, as well as moderating ground temperatures. They are also vital elements in landscaping and agriculture, both for their aesthetic appeal and their orchard crops (such as apples). Wood from trees is a common building material. Trees also play an intimate role in many of the world's mythologies.

It was the sixth-strongest Atlantic hurricane that was ever recorded and the third-strongest hurricane on record that made landfall in the United States. Katrina formed on August 23 during the 2005 Atlantic hurricane season and caused devastation along the north-central Gulf Coast. The most severe loss of life and property damage occurred in New Orleans, Louisiana, which flooded as the levee system catastrophically failed; in many cases hours after the storm had moved inland. In the 2005 Atlantic season, Katrina was the eleventh tropical storm, fifth hurricane, third major hurricane, and second Category 5 hurricane.

This movement of the plates releases stress that accumulates along geologic faults. A fault is a deep crack that marks the boundary between two of the plates. Earthquake belts occur along faults all around the world. Many run along coastal areas. The San Andreas Fault in central California is well-known for causing most severe earthquakes. The epicenter is the point on the surface where the earthquake is strongest. The Richter scale is used to measure the amount of energy that is released by the earthquake.&lt;/p&gt;

These plants are native to humid and subtropical southern Asia and southeastern Africa. Rice provides more than one fifth of the calories consumed global by humans.(The term "wild rice" can refer to the wild species of Oryza, but predictably refers to species of the related genus Zizania, both wild and domesticated.) Rice is grown as a monocarpic annual plant, although in tropical areas it can endure as a perpetual and can produce a ratoon crop.  Rice can grow to 1–1.8 m tall, intermittently more depending on the variety and soil fecundity. The grass has long, slender leaves 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are shaped in a branched arching to pendulous inflorescence 30–50 cm long. The seed is a particle (caryopsis) 5–12 mm long and 2–3 mm thick.&lt;/p&gt;
	&lt;p&gt;Rice is a fasten for a large part of the world's human populace, especially in East, South and Southeast Asia, making it the most consumed cereal grain. Rice cultivation is well-suited to countries and regions with low labour costs and high precipitation, as it is very labour-intensive to develop and requires plenty of water for cultivation.&lt;/p&gt;
	&lt;p&gt;Rice can be grown virtually anywhere, even on steep hillsides. Although its species are native to South Asia and certain parts of Africa, centuries of trade and exportation have made it humdrum in many cultures.&lt;/p&gt;
	&lt;p&gt;The conventional method for cultivating rice is flooding the fields with or after setting the young seedlings. This simple method requires sound planning and servicing of the water damming and channeling, but reduces the growth of lesser strong tidy and pest plants and reduces vermin that has no submerged growth state. However, with rice growing and agriculture the flooding is not mandatory, whereas all other methods of irrigation require higher effort in weed and pest control during growth periods and a different draw near for fertilizing the mud.&lt;/p&gt;

It contains roughly 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor. This mixture of gases is commonly known as air. The atmosphere protects life on Earth by absorbing ultraviolet solar emission and reducing temperature extremes between day and night.&lt;/p&gt;
	&lt;p&gt;There is no definite boundary between the atmosphere and outer space. It slowly becomes thinner and fades into space. Three quarters of the atmosphere's mass is within 11 km of the terrestrial surface. In the United States, people who travel above an elevation of 80.5 km (50 statute miles) are designated astronauts. An altitude of 120 km (~75 miles or 400,000 ft) marks the periphery where distinctive effects become noticeable during re-entry. The Kármán line, at 100 km (62 miles or 328,000 ft), is also frequently regarded as the margin between atmosphere and outer space.&lt;/p&gt;

However, the term "virus" is commonly used, albeit speciously, to refer to many different types of malware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. Meanwhile viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A maggot can spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a file that appears harmless. Both worms and Trojans will make harm to computers when executed.&lt;/p&gt;
	&lt;p&gt;Most personal computers are now connected to the Internet and to local area networks, facilitating the spread of malevolent code. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, Instant Messaging and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative expressions in which a virus is any form of self-replicating malware.&lt;/p&gt;
	&lt;p&gt;Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply repeat themselves and perhaps make their existence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by genuine programs. As a result, they often cause changeable behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.&lt;/p&gt;

The falls are located 17 miles (27 km) north-northwest of Buffalo, New York, 75 miles (120 km) south-southeast of Toronto, Ontario, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York.&lt;/p&gt;
	&lt;p&gt;Niagara Falls is composed of two major sections parted by Goat Island: Horseshoe Falls, on the Canadian side of the border and American Falls on the United States side. The smaller Bridal Veil Falls also is located on the American side, separated from the main falls by Luna Island. Niagara Falls were formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly-formed Great Lakes stamped a path through the Niagara Escarpment en route to the Atlantic Ocean. While not exceptionally high, the Niagara Falls are very extensive. More than six million cubic feet (168,000 m³) of water fall over the crest line every minute in high flow, and almost 4 million cubic feet (110,000 m³) on average. It is the most powerful waterfall in North America.&lt;/p&gt;
	&lt;p&gt;The Niagara Falls are renowned both for their beauty and as a precious source of hydroelectric power (Sir Adam Beck Generating Station)EST 1917. Managing the balance between leisure, commercial, and industrial uses has been a challenge for the stewards of the falls since the 1800s.&lt;/p&gt;

In larger rivers there is also a wider flood-plain shaped by flood-waters over-topping the feed. Flood plains may be very wide in relative to the size of the river channel. This dissimilarity between river channel and flood-plain can be blurred especially in urban areas where the flood-plain of a river channel can become greatly developed by housing and industry.&lt;/p&gt;
	&lt;p&gt;The river channel itself typically contains a single stream of water but some rivers flow as several interconnecting streams of water, producing a braided river. All-embracing braided rivers are found in only a few regions worldwide, such as the South Island of New Zealand. They also occur on peneplains and some of the larger river deltas. Anastamosing rivers are similar to braided rivers. They have multiple graceful channels carrying large volumes of sediment. Due to the dynamics of this type of system, they are also quite rare.&lt;/p&gt;
	&lt;p&gt;A river flowing in its channel is a source of energy which acts on the river channel to change its shape and form. In steep torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the devastation of larger rocks. In U shaped glaciated valleys, the consequent river valley can often easily be identified by the V shaped channel that it has carved. In the middle reaches where the river may flow over flatter land, loops (meanders) may form through eroding of the river banks and declaration on the inside of bends. Sometimes the river will cut off a loop, shortening the channel and forming an oxbow lake or billabong. Rivers that carry large amounts of deposit may develop conspicuous deltas at their mouths, if conditions permit. Rivers, whose mouths are in brackish tidal waters, may form estuaries. River mouths may also be fjords or rias.&lt;/p&gt;

With extraordinary large males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions presently exist in sub-Saharan Africa and in Asia with a dangerously endangered residue population in northwest India, having disappeared from North Africa, the Middle East, and western Asia in historic times. Until the late Pleistocene, the lion was the most pervasive large land mammal beside humans. They were found in most of Africa, much of Eurasia from western Europe to India, and the Bering land bridge and, in the Americas, from the Yukon to Peru.&lt;/p&gt;
	&lt;p&gt;Lions live for approximately 10–14 years in the wild, while in confinement they can live over 20 years. They typically occupy savanna and grassland, although they may take to bush and forest. Lions are unusually social compared to other cats. A arrogance of lions consists of related females and offspring and a small number of adult males. Groups of female lions typically hunt together, preying mostly on large ungulates. The lion is an apex and keystone killer, although they will resort to scavenging if the opportunity arises. While lions, in general, do not selectively hunt humans, some have been known to become man-eaters and seek human victim.&lt;/p&gt;
	&lt;p&gt;The lion is a exposed species, having seen a possibly irretrievable population refuse of 30 to 50% over the past two decades in its African range; populations are unsound outside designated reserves and national parks. Although the cause of the decline is not well-understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Lions have been kept in menageries since Roman times and have been a key species sought after and exhibited in zoos the world over since the late eighteenth century. Zoos are cooperating worldwide in breeding programs for the endangered Asiatic subspecies.&lt;/p&gt;
	&lt;p&gt;The male lion is highly individual and is easily recognized by its mane. The head of the male lion, is one of the most widely recognized animal symbols in human culture. It has been depicted extensively in literature, in sculptures, in paintings, on national flags, and in fashionable films and journalism.&lt;/p&gt;

It is easily sophisticated and there are now more than 1,000 cultivars, ranging from the "turpentine mango" (named for its strong taste of turpentine, which according to the Oxford Companion to Food some varieties essentially control) to the huevos de toro. &lt;/p&gt;
	&lt;p&gt;The mango is a popular fruit with people around the world. However, many mango farmers accept a low price for their produce. This has led to mangoes being available as a just trade item in some countries. Dwarf or semi-dwarf varities, such as Nam Doc Mai can be grown and fruit in containers. They will need constant care and scale maybe difficult.&lt;/p&gt;
	&lt;p&gt;The pigment euxanthin, usually known as Indian yellow, is often described as having been produced from the urine of cows fed on mango leaves; the practice is described as having been outlawed in 1908 after having been found to cause starvation in the cows. However, Victoria Finlay has shown that these descriptions of the pigment's origin all rely on a single undependable source, that there exist no other records of the pigment being produced in such a fashion, and that Indian legal records do not mention any such practice ever being outlawed. As such, the capability of the pigment's making from mango-leaf-fed cows is unknown.&lt;/p&gt;

It is bounded on the north by Asia (including the Indian subcontinent, after which it is named); on the west by Africa; on the east by Indochina, the Sunda Islands, and Australia; and on the south by the Southern Ocean (or, traditionally, by Antarctica). One module of the broad World Ocean, the Indian Ocean is delineated from the Atlantic Ocean by the 20° east meridian running south from Cape Agulhas, and from the Pacific by the 147° east meridian. The northernmost extent of the Indian Ocean is approximately 30° north autonomy in the Persian Gulf and, thus, has asymmetric ocean circulation. This ocean is nearly 10,000 kilometres (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometres (28,400,000 mi²), including the Red Sea and the Persian Gulf.&lt;/p&gt;
	&lt;p&gt;The ocean's volume is estimated to be 292,131,000 cubic kilometers (70,086,000 mi³). Small islands dot the continental rims. Island nations within the ocean are Madagascar (formerly Malagasy Republic), the world's fourth chief island; Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka. Indonesia borders it on the east. The ocean's importance as a transit route between Asia and Africa has made it a scene of conflict. Because of its size, however, no nation had effectively dominated most of it until the early 1800s when the United Kingdom controlled much of the surrounding land. After the refuse of the British Empire, the ocean has been conquered by India and Australia.&lt;/p&gt;

Communication requires that all parties understand a common language that is exchanged. There are auditory means, such as speaking or singing, and nonverbal, physical means, such as body language, sign language, paralanguage, touch, eye contact, or the use of writing. &lt;br&gt;&lt;br&gt;Communication happens at many levels (even for one single action), in many different ways, and for most beings, as well as certain machines. Several, if not all, fields of study dedicate a portion of attention to communication, so when speaking about communication it is very important to be sure about what aspects of communication one is speaking about. Definitions of communication range widely, some recognizing that animals can communicate with each other as well as human beings, and some are narrower, only including human beings within the parameters of human symbolic interaction. &lt;br&gt;&lt;br&gt;Nonetheless, communication is usually described along a few major dimensions: &lt;br&gt;&lt;br&gt;&lt;br&gt;
   1. Content (what type of things are communicated)&lt;br&gt;
   2. Source (by whom)&lt;br&gt;
   3. Form (in which form)&lt;br&gt;
   4. Channel (through which medium)&lt;br&gt;
   5. Destination/Receiver (to whom)&lt;br&gt;
   6. Purpose/Pragmatic aspect (with what kind of results). &lt;/p&gt;

Native to the mainland of southeastern Asia, the tiger is an apex predator and the largest feline species in the world, similar in size to the biggest fossil felids. The Bengal Tiger is the most general subspecies of tiger, constituting approximately 80% of the entire tiger population, and is found in India, Bangladesh, Bhutan, Myanmar, and Nepal. An endangered species, the popular of the world's tigers now live in captivity.&lt;/p&gt;
	&lt;p&gt;The tiger is introverted and territorial, preferring cover in deep forest, but also ranging in open areas. The cat hunts by stalk-and-ambush and may take a variety of mid- and large-sized prey, particularly ungulates. Males are much larger than females and have bigger home ranges. Amongst the nine extant tiger subspecies, there is major size variation.&lt;/p&gt;

Natural was a Latin translation of the Greek word physis, which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. This is shown in the first written use of the word, in connection with a plant. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word by pre-Socratic philosophers, and has steadily gained currency ever since. This usage was confirmed during the advent of modern scientific method in the last several centuries.&lt;br&gt;&lt;br&gt;Within the various uses of the word today, "nature" may refer to the general realm of various types of living plants and animals, and in some cases to the processes associated with inanimate objects - the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth, and the matter and energy of which all these things are composed. It is often taken to mean the "natural environment" or wilderness - wild animals, rocks, forest, beaches, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention. This more traditional concept of natural things which can still be found today implies a distinction between the natural and the artificial, with the latter being understood as that which has been brought into being by a human or human-like consciousness or mind.

They are raised as livestock for meat dairy products (milk), leather and as draught animals. In some countries, such as India, they are honored in religious ceremonies and revered. It is expected that there are 1.4 billion head of cattle in the world today.&lt;/p&gt;
	&lt;p&gt;Cattle were originally known by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia, Bos indicus, the zebu,and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to together zebu and European cattle. More newly these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius. Complicating the matter is the capacity of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks, banteng, gaur, and bison, a cross-genera fusion. Cattle cannot effectively be bred with water buffalo or African buffalo. &lt;/p&gt;

That unrealistic representation of women that the media bombards young women with indicates that the television has become a source for a distorted understanding of gender roles among adolescent women. The images which are warping the young women's views of their own gender identity. The media on television which should in an attempt to provide more positive gender identities for adolescent women depict women on television in more realistic ways, should stop reinforcing negative stereotypes of women, and stop portraying women as sex objects in advertising. &lt;/p&gt;
	&lt;p&gt;Subsequently, the advertisers see women as parts. Teenage girls – they should be represented on television as being able to have serious conversations and feeling that their brains are as important as their looks. The result of these images is that these ideas create competition among women and divides women. Women should be represented as more than the standard stereotypical negative and simplified character viewers who generally see. The media especially television often focus on legs, breasts and mouth of a woman, so in essence women are looked at in pieces. Women are needed to be shown in occupations that are not the stereotypical, such as the occupations of nurse, maid, sales assistant, or models. Although, the girls who are coming in advertisements are often seen playing house while little boys are seen with trucks and action figures. The television should represent traditional views of society. For all the above said reasons, society should have a deep concern with the gender roles that young women are learning from television. Often Women has been shown as only being able to get what they want by using sexuality &lt;/p&gt;

Inherent in the term is the design that the mode will vary more quickly than the culture as a total. The terms "fashionable" and "unfashionable" are in use to describe whether somebody or something fits in with the recent popular mode of appearance. The term "fashion" is regularly used in a positive sense, as a synonym for glamour and style. In this sense, fashions are a type of public art, through which a culture examines its design of beauty and goodness. The term "fashion" is as well sometimes used in a negative sense, as a synonym for fads, trends, and greed.&lt;/p&gt;
	&lt;p&gt;Fashion in clothes has acceptable wearers to express feeling or unity with other people for millennia. Modern Westerners have an extensive choice presented in the selection of their clothes. What a person chooses to dress in can reflect that person's personality or likes. When people who have cultural type start to wear new or different clothes a fashion trend may start. People who like or esteem them may start to wear clothes of a similar style.&lt;/p&gt;

Early electronic computers were the size of a large room, overriding as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to distinguish personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as a computer. However, the most general form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to organize other devices—for example; they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.&lt;br&gt;
The ability to store and implement programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this flexibility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capability are not considerations.&lt;/p&gt;

Data thus controlled is said to be blocked. The process of putting data into blocks is called blocking. Blocking is used to assist the handling of the data-stream by the computer program receiving the data. Blocked data is generally read a block at a time. Blocking is almost universally employed when storing data to 9-track magnetic tape, to turning media such as floppy disks, hard disks, and optical discs, and to NAND flash memory.&lt;br&gt;
Block storage is normally abstract by a file system or database management system for use by applications and end users. Database management systems(DBMS) often use their own Block I/O for superior performance and recoverability as compare to layering the DBMS on top of a file system.&lt;/p&gt;

Laptops usually run on a single main battery or from an external AC/DC adapter which can blame the battery while also supplying power to the processor itself. Many computers also have a 3 volt cell to run the clock and other processes in the occurrence of a power failure.&lt;br&gt;
As personal computers, laptops are skilled of the same tasks as a desktop computer, although they are classically less powerful for the similar price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and capable power consumption. Laptops usually have liquid crystal displays and most of them use unusual memory modules for their chance access memory (RAM), for instance, SO-DIMM in lieu of the superior DIMMs. In addition to a built-in keyboard, they may utilize a touchpad or a pointing stick for input, though an outside keyboard or mouse can frequently be attached.&lt;/p&gt;

The elementary element that defines light is the photon. The three basic properties of lights are Intensity, or alternatively amplitude, which is related to the observation of brightness of the light, Frequency, or alternatively wavelength, perceived by humans as the color of the light, and Polarization, which is only weakly perceptible by humans under ordinary circumstances. Due to its wave–particle duality, light can show properties of both waves and particles. The study of light, known as optics, is an important research area in modern physics&lt;br&gt;
The first successful quantity of the speed of light in Europe using an earthbound apparatus was carried out by Hippolyte Fizeau in 1849. Fizeau aimed at a beam of light at a mirror several thousand metres away, and placed a rotating cog wheel in the path of the beam from the source to the mirror and back again. At a certain rate of rotary motion, the beam could pass through one gap in the wheel on the way out and the next gap on the way back. Knowing the distance to the mirror, the number of teeth on the wheel, and the rate of rotation, Fizeau calculated the speed of light as 313 000 km/sv&lt;/p&gt;

In popular use, the term today usually refers to an electronic amplifier, often as in audio applications. The relationship of the input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain.&lt;br&gt;
The bandwidth (BW) of an amplifier is usually defined as the difference between the lower and upper half power points. This is therefore also known as the -3 dB BW. Bandwidths for other response tolerances are sometimes quoted (-1 dB, -6 dB etc.).&lt;br&gt;
Many amplifiers are ultimately slew rate limited, which may limit the full power bandwidth to frequencies well below the amplifiers frequency response when dealing with small signals.&lt;/p&gt;

A non-toothed wheel can transmit some tangential force but will slip if the force is large; teeth put off slippage and permit the transmission of large forces.&lt;/p&gt;
	&lt;p&gt;A gear can mesh with any device having teeth friendly with the gear's teeth. Such devices include racks and other non-rotating policy; however, the most common condition is for a gear to be in mesh with another gear. In this case revolution of one of the gears necessarily causes the other gear to rotate. In this way, rotational motion can be transferred from one position to another. While gears are sometimes used simply for this reason to transmit rotation to another shaft perhaps their most significant feature is that, if the gears are of asymmetrical sizes, a mechanical advantage is also achieved, so that the rotational speed, and torque, of the second gear are dissimilar from that of the first. In this way, gears provide a means of increasing or decreasing a turning speed, or a torque&lt;/p&gt;

This can take the form of being protected from the event or from exposure to something that causes health or reasonable losses. There also are two slightly different meanings of safety, a safety home may indicate its protection ability against external harm events, and the second that its internal installations are safe for its habitants.&lt;/p&gt;
	&lt;p&gt;Safety can be limited in relative to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization. It is used in order to ensure that the object or association will do only what it is meant to do. Normative safety is a term used to explain products or designs that meet applicable design standards. Substantive safety stands for that the real-world safety history is favorable, whether or not standards are met. Perceived safety refers to the stage of comfort of users&lt;/p&gt;

Modern electricity meters operate by continuously measuring the instantaneous voltage and current (amperes) and finding the product of these to give direct electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc). The meters fall into two essential categories, electromechanical and electronic. The type of meter described commonly used on a single-phase AC supply. Different phase of meter configurations use additional voltage and current coils. The most general type of electricity meter is the electromechanical induction meter.&lt;/p&gt;

As a power-driven, continuous moving stairway planned to transport passengers up and down short vertical distances, escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage include shopping centers, airports, transit systems, convention centers, hotels, and public buildings.&lt;/p&gt;
	&lt;p&gt;They have the capacity to move large numbers of people, and they can be placed in the same physical space as set of steps. They have no waiting interval, except during very heavy traffic, they can be used to guide people towards main exits and they may be weather-proofed for outdoor use.&lt;/p&gt;

In quantum field theory, the activities of the electron are described by quantum electrodynamics, a gauge theory. In Dirac's model, an electron is defined to be a mathematical point, a point-like, exciting bare particle surrounded by a sea of interacting pairs of virtual particles and antiparticles. The extraordinarily precise agreement of this forecast with the experimentally resolute value is viewed as one of the great achievements of modern physics.&lt;/p&gt;
	&lt;p&gt;In the Standard Model of particle physics, the electron is the first-generation stimulating lepton. It forms a weak isospin doublet with the electron neutrino, these two particles cooperate with each other through both the charged and neutral current weak interaction. The electron is very similar to the two more massive particles of higher generations, the muon and the tau lepton, which are identical in charge, spin, and interface but differ in mass.&lt;/p&gt;
