They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Capacitance
The dielectric constant for a number of very useful dielectrics changes as a function of the applied electrical field, e.g. ferroelectric materials, so the capacitance for these devices is no longer purely a purpose of device geometry. If a capacitor is driven with a sinusoidal voltage, the dielectric constant, or more exactly referred to as the dielectric permittivity, is a function of frequency. A changing dielectric constant with frequency is referred to as a dielectric dispersion, and is governed by dielectric recreation processes, such as Debye relaxation.

Energy meter
The most common type is more accurately known as a (kilo) watt-hour meter or a joule meter. They may also record other variables including the time, when the electricity was used. 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.

Festival
Festivals are many types, serve to meet specific social needs and duties, as well as to present entertainment. These times of celebration offer a intellect of belonging for religious, social, or geographical groups. Modern festivals that focus on educational or ethnic topics seek to inform members of their traditions. In past times, festivals were times when the elderly shared stories and transferred convinced knowledge to the next generation. Historic feast often provided a means for unity among families and for people to come across mates. Select anniversaries have annual festivals to celebrate previous significant occurrences.

House
A house is a pattern used for habitation by people that generally has walls and a roof to shelter its enclosed space from precipitation, wind, heat, cold, and other elements. Animals including both domestic pets and unwanted animals often live in houses. The word house may also refer to a construction that shelters animals, especially within a zoo. The social unit that dwells in a house is known as a household. Most commonly, a household is a family unit of some kind, though households can be other social groups, such as single persons, or groups of unconnected individuals. Settled agrarian and industrial societies are composed of household units living permanently in housing of various types, according to a selection of forms of Land tenure. English-speaking people generally call any building they routinely occupy home. Many people leave their house during the day for work and activity but typically return to it to sleep or for other activities.

Database
The fundamental form of data is stored in the data bases. When data is large we modify it in the form of data where house. Data where house is that place where numerous data stand are stored. When a data base application is created and close to data base, certain properties are reserve in mind. In application different users are created and given certain human rights. Some of them are made supervisor while others are made users. When we create a exacting application for a company or a business administration. These types of application include different task behavior which mainly involves conclusion making and also present and future line of work. The application is made with full expertise which on analyzing makes a business man winning. This application also includes data store which contains information about employee’s personal information, pay scale, etc..

Nuclear weapon
During the closing days of World War II nuclear weapons have been used twice and the first event was United States dropped uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima on August 6, 1945. Three days later it dropped a plutonium implosion-type device code-named "Fat Man" on the city of Nagasaki.These events killed around 100,000 to 200,000 people and still it’s affecting the newborn –babies.
United States, Soviet Union, United Kingdom, France, People's Republic of China, India, Pakistan, and North Korea are the countries known to have detonated nuclear weapons.Iran attempting to develop nuclear capabilities, though its government claims that it’s acknowledged nuclear activities, such as uranium enrichment, is for peaceful purposes currently. Nuclear explosives have been used for various non-military uses also.

Radio
Radio was used to pass on orders and communications between armies and navies on both sides in World War I; Germany used radio communications for diplomatic messages once its submarine cables were cut by the British. The United States passed on President Woodrow Wilson's Fourteen Points to Germany via radio during the war. Broadcasting began from San Jose in 1909[4], and became feasible in the 1920s, with the widespread introduction of radio receivers, particularly in Europe and the United States. Besides broadcasting, point-to-point broadcasting, including telephone messages and relays of radio programs, became widespread in the 1920s and 1930s. Another use of radio in the pre-war years was the development of detecting and locating aircraft and ships by the use of radar (RAdio Detection And Ranging).
Today, radio takes many forms, including wireless networks, mobile communications of all types, as well as radio broadcasting. Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment. Radio was unique among dramatic presentation that it used only sound. For more, see radio programming.
News
There are many categories of news. The weather is typically presented by a certified meteorologist or, on smaller stations, a less-trained "weatherman" and is considered news. Other news categories are: sports, fashion, society, entertainment, business, cartoon strips, features, lottery numbers, lives of celebrities, advertising, and more. Until the 1970s, when women's lib issues came to the forefront, most newspapers had a "Women's" section devoted entirely to fashion and society news. Papers even printed "cheesecake" feature photos of attractive young women in bikinis, often transmitted by the AP or UPI wire services, illustrating various news events or feature ideas.

Collateral damage
Etymologically, the expression "collateral damage" probably was originally used as military doublespeak rather than a euphemism, as the adjective "collateral" doesn't seem to have been used as a synonym for "unintentional" or "accidental" earlier. However, "collateral" may also sometimes mean "additional but subordinate," i.e. "secondary", and that specific meaning of a rather obscure word in the English language seems to have been picked up and broadened by the military in the expression "collateral damage."

Bond
A bond is simply a loan, but in the form of a security, although terminology used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the coupon to the interest. Bonds enable the issuer to finance long-term investments with external funds. Debt securities with a maturity shorter than one year are typically bills. Certificates of deposit or commercial paper are measured money market instruments.

Culture of Bhutan
The habitual dress for Ngalong and Sharchop men is the gho, a knee-length robe tied at the waist by a cloth belt known as the kera. Women wear an ankle-length dress, the kira, which is clipped at one shoulder and coupled at the waist. Social status and class determine the quality, colours, and decorations that embellish the garments. Scarves and shawls are also indicators of social standings, as Bhutan has conventionally been a feudal society. Earrings are worn by females. Controversially, Bhutanese law now requires these garments for all Bhutanese citizens.

Japanese Fashion Design
The majority of Japanese fashion houses are based in Tokyo. The Japanese "look" is loose and apparently unstructured though this can often be the result of complicated cutting techniques. Colors are often sombre and subtle and the fabrics used are richly textured. Many of the most famous names in Japanese fashion now work in Europe or the USA, but the Tokyo designer collections are still a major international event. Famous names in Japanese fashion include Kenzo, Issey Miyake, and Rei Kawakubo who developed a completely new way of cutting.

Crocodile
Crocodiles are the most higher of all reptiles despite their prehistoric look. Unlike other reptiles they have a four-chambered heart, diaphragm and intellectual cortex. Their outside morphology on the other hand is a sign of their aquatic and predatory lifestyle. A crocodile’s bodily traits allow it to be a successful predator. They have a smooth body that enables them to swim faster. They also insert their feet to their sides while swimming, which makes the animal even faster, by decreasing the amount of water resistance. They have webbed feet, although not used to propel the animal through the water, this allows it to make fast turns and sudden moves in the water or start swimming. Webbed feet are an advantage in shallower water where the animals sometimes move around by walking.
Crocodiles are extremely fast over short distances, even out of water. They have very powerful jaws and sharp teeth for tearing flesh, but cannot open their mouth if it is held closed, hence there are stories of people escaping from the long-snouted Nile crocodile by holding its jaws shut. Indeed, zoologists will often restrain crocodiles for study or transport by taping their jaws or holding their jaws shut with large rubber bands cut from automobile inner tubes. All huge crocodiles also have sharp welters and powerful claws. They have partial lateral movement in their neck, so on land one can find protection by getting even a small tree between the crocodile's jaws and oneself.
Crocodiles eat fish, birds, mammals and infrequently smaller crocodiles. Wild crocodiles are protected in many parts of the world, but they also are farmed commercially. Their hide is tanned and used to make leather goods such as shoes and handbags, whilst crocodile meat is also measured a delicacy in many parts of the world. The most usually farmed species are the Saltwater and Nile crocodiles, while a hybrid of the Saltwater and the rare Siamese Crocodile is also bred in Asian farms. Farming has resulted in an increase in the Saltwater Crocodile population in Australia, as eggs are usually harvested from the wild, so landowners have an incentive to keep crocodile habitat. Crocodiles are more closely related to birds and dinosaurs than to most animals classified as reptiles, the three being included in the group Archosauria ('ruling reptiles').

Jewellery
Jewellery is factually any piece of fine material used to decorate oneself. Although in earlier times jewellery was created for more convenient uses, such as wealth storage and pinning clothes together, in recent times it has been used almost completely for beautification.
The first pieces of jewellery were made from likely materials, such as bone and animal teeth, shell, wood and engraved stone. Jewellery was often made for people of high importance to show their status and, in many cases, they were covered with it.Jewellery is made out of almost every material recognized and has been made to garnish nearly every body part, from hairpins to toe rings and many more types of jewellery. While high-quality and artistic pieces are made with gemstones and valuable metals, less pricey costume jewellery is made from less-valuable materials and is mass-produced.Form and function Kenyan man exhausting tribal beads.Over time, jewellery has been used for a number of reasons: Currency, wealth display and storage,purposeful Symbolism Protection and Artistic display Most cultures have at some point had a practice of observance large amounts of wealth stored in the form of jewellery. Numerous cultures move wedding dowries in the form of jewelry, or create jewelry as a means to store or display coins. on the other hand, jewellery has been used as a currency or trade good; a mostly poignant example being the use of slave beads.
In creating jewellery, a variety of gemstones, coins, or other valuable items can be used, often set into precious metals. Common expensive metals used for modern jewellery include gold, platinum or silver, although alloys of nearly every metal known can be encountered in jewellery -- bronze, for example, was common in Roman times. Most gold jewellery is made of an alloy of gold, the purity of which is affirmed in karats, indicated by a number followed by the letter K. For example, ordinary gold jewellery ranges from 10K (41.7% pure gold) to 22K (91.6% pure gold), while 24K (99.9% pure gold) is considered too soft for jewellery use.
Platinum alloys variety from 900 (90% pure) to 950 (95.0% pure). The silver used in jewellery is usually sterling silver, or 92.5% fine silver.Other generally used materials include glass, such as merged glass or enamel; wood, often carved or turned; shells and other natural animal substances such as bone and ivory; natural clay, polymer clay, and even plastics.
Jewellery and society
One universal issue is control over who could wear what jewellery, a point which indicate the powerful symbolism the wearing of jewellery evoked. In ancient Rome, for instance, only convinced ranks could wear rings; later, sumptuary laws dictated who could wear what type of jewellery; again based on rank. Cultural dictate have also played a important role; for example, the wearing of earrings by Western men was considered "effeminate" in the 19th and early 20th centuries. on the other hand, the jewellery industry in the early 20th century launched a crusade to popularize wedding rings for men - which caught on - as well as appointment rings for men , going so far as to make a false history and claim that the practice had Medieval roots. By the mid 1940s, 85% of weddings in the U.S. feature a double-ring ceremony, up from 15% in the 1920s.Religion has also played a role: Islam, for instance, consider the wearing of gold by men as a social taboo,and many religions have edicts against extreme display.

Nasiruddin Humayun
Nasiruddin Humayun:
He was the second Mughal emperor and ruled northern parts of
He succeeded his father in India in 1530, while his half-brother Kamran Mirza, who was to become a rather bitter rival, obtained the sovereignty of Kabul and Lahore, the more northern parts of their fathers empire. He originally ascended the throne at the age of 22 and was somewhat inexperienced when he came to power. Humayun lost his Indian territories to the Afghan Sultan, Sher Shah, and only regained them with Persian aid ten years later. Subsequently, in a very short time thereafter, Humayun was able to expand the Empire further, leaving a substantial legacy for his son, Akbar the Great.
