Locks

Generally, locks are advisory locks, where each thread cooperates by acquiring the lock before accessing the equivalent data. Some systems also implement mandatory locks, where attempting unauthorized access to a locked resource will force exclusion in the entity attempting to make the access.

In terms of access to the data, no difference is made between shared or exclusive modes. Other schemes provide for a shared mode, where several threads can obtain a shared lock for read-only access to the data. Other modes such as exclusive, intend-to-exclude and intend-to-upgrade are also widely implemented.

Independent of the type of lock chosen above, locks can be confidential by what happens when the lock strategy prevents progress of a thread. Most locking designs block the finishing of the process requesting the lock until it is allowed to access the locked resource. A spin lock is a lock where the thread simply waits until the lock becomes accessible. It is very efficient if threads are only likely to be uncreative for a short period of time, as it avoids the overhead of operating system process re-scheduling. It is wasteful if the padlock is held for a long period of time.

Color

Color is the visual perceptual possessions corresponding in humans to the categories called red, yellow, white, etc. Color derives from spectrum of light distribution of light energy versus wavelength interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical condition of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.

Typically, only features of the composition of light that are visible by humans wavelength spectrum from 400 nm to 700 nm, roughly are included, thereby objectively relating the psychological phenomenon of color to its physical specification. Because perception of color stems from the varying sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantify by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully clarify the psychophysical perception of color appearance.

The science of color is sometimes called chromatics. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic emission in the visible range that is, what we commonly refer to simply as light.

Voltage

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, uttered in volts. It measures the potential energy of an electric field to source an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.

Between two points in an electric field, such as exists in an electrical circuit, the distinction in their electrical potentials is known as the electrical potential difference. This difference is proportional to the electrostatic force that tends to drive electrons or other charge-carriers from one point to the other. Potential difference, electrical potential, and electromotive force are measured in volts, leading to the commonly used term voltage. Voltage is usually represented in equations by the symbols V, U, or E.

Electrical potential difference can be thought of as the capacity to move electrical charge through a resistance. At a time in physics when the word force was used loosely, the potential difference was named the electromotive force or EMF—a term which is still used in confident contexts.

Nanny

A nanny is defined as a child's nurse. The traditional nanny was a servant in a large household and reported directly to the lady of the house. Nannies were always female and this remained the case through the 20th Century. This role currently stands firmly as a sector of early childhood education.The nanny in a great house ran her own tiny domain, supported by at least one nursery maid. Because of their role in child care, they were somewhat more indulged than junior servants. Nannies may have remained in the employ of the same aristocratic family for years, looking after successive generations of children.

Today, although many families employ part-time babysitters, fulltime nannies in the classic sense can only be afforded by upper-middle to upper class families.Typically, girls and women in the 20 to 30 age bracket take up employment as nannies. Some are younger. In many poorer countries, many teenage girls also work as nannies. Nannies typically earn low salaries. Sometimes the employer requires their nanny/nannies to wear a uniform. This happened often earlier during the 20th century, but since the 1990s many nannies instead can wear clothes that are comfortable for their work. A nanny uniform can include a dress or blouse and skirt.

Football

Football is the name given to a number of different, but related, team sports. The most popular of these world-wide is association football (also known as soccer). The English word "football" is also applied to American football, Australian rules football, Canadian football, Gaelic football, rugby football (rugby union and rugby league), and related games. Each of these codes (specific sets of rules) is to a greater or lesser extent referred to as "football" and sometimes "footy" by its followers.
These games involve:
a large spherical or prolate spheroid ball, which is itself called a football. a team scoring goals and/or points, by moving the ball to an opposing team's end of the field and either into a goal area, or over a line. the goal and/or line being defended by the opposing team. players being required to move the ball mostly by kicking and — in some codes — carrying and/or passing the ball by hand. goals and/or points resulting from players putting the ball between two goalposts. offside rules, in most codes, restricting the movement of players. in some codes, points are mostly scored by players carrying the ball across the goal line. in most codes players scoring a goal must put the ball either under or over a crossbar between the goalposts. players in some codes receiving a free kick after they take a mark/make a fair catch. Many of the modern games have their origins in England, but many peoples around the world have played games which involved kicking and/or carrying a ball since ancient times.

Village

A village is a clustered human settlement or community, larger than a hamlet, but smaller than a town or city[1]. Though generally located in rural areas, the term urban village may be applied to certain urban neighbourhoods. Villages normally are permanent with fixed dwellings, however transient villages[2] can occur. Further, the dwellings of a village are fairly close to one another, as against being scattered broadly over the landscape (‘dispersed settlement’).
Throughout the human past, villages have been the usual form of community for agricultural societies, and even for some non-agricultural societies. Towns and cities were few, and were home to only a small proportion of the population. The Industrial Revolution caused many villages to grow into towns and cities; this trend of urbanisation has continued and hastened since, though not always in connection with industrialisation. Villages have thus been eclipsed in importance, as units of human society and settlement.

Fashion and the process of change

Fashion, by definition, changes continuously. The changes may progress more quickly than in most other fields of human activity. For some, modern fast-paced changes in fashion embody many of the negative aspects of capitalism: it results in waste and encourages people qua consumers to buy things unreasonably. Others, especially young people, enjoy the diversity that changing fashion can apparently offer, seeing the constant change as a way to satisfy their wish to experience "new" and "interesting" things. Note too that fashion can change to enforce regularity, as in the case where so-called Mao suits became the national uniform of mainland China.

Bankruptcy

Bankruptcy is a lawfully affirmed incapability or impairment of ability of an individual or organization to pay their creditors. Creditors may file bankruptcy for a debtor in an effort to recoup a portion of what they are owed. In the most of the cases, bankruptcy is initiated by the debtor.

The main reason of bankruptcy is to give an honest debtor a fresh start in life by reducing the debtor of most debts, and to repay creditors in an orderly manner to the extent that the debtor has the means available for payment. Bankruptcy allows debtors to resolve debts through the division of non-exempt assets among creditors. In addition the declaration of bankruptcy allows debtors to be discharge most of the financial obligations, after their non exempt assets are dispersed, even if their debts have not been paid in full.

Culture of China

For centuries, opportunity for economic and social advancement in China could be provided by high performance on majestic examinations. The literary emphasis of the exams affected the common perception of cultural refinement in China, such as the view that calligraphy and literati painting were higher forms of art than dancing or drama. China's traditional values were derivative from various versions of Confucianism and conservatism. A number of more authoritarian strains of thought have also been influential, such as Legalism. There was often clash between the philosophies, such as the individualistic Song Dynasty neo-Confucians, who believed Legalism departed from the original spirit of Confucianism. Examinations and a culture of merit remain greatly valued in China today. In recent years, a number of New Confucians have advocated that democratic ethics and human rights are quite compatible with traditional Confucian "Asian values".

Areas of Work Designers

There are three main ways in which designers can work:
Working freelance: Freelance designers work for themselves. They sell their work to fashion houses, direct to shops, or to clothing manufacturers. The garments bear the buyer's label.

Working In-house: In-house designers are employed full-time by one Fashion Company. Their designs are the property of that company, and cannot be sold to anyone else.

Setting up a Company: Fashion designers often set up their own companies. Many people find this more satisfying than working for someone else, as their designs are sold under their own label.

Cranes

Cranes are large, long-legged and long-necked birds of the order Gruiformes, and relatives Gruidae. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Most have complicated and noisy courting displays or "dances". While folklore often states that cranes friend for life, recent scientific research indicates that these birds do alter mates over the course of their lifetimes. Some species and/or populations of cranes travel over long distances, while some do not migrate at all. Cranes are gregarious, forming huge flocks where their numbers are sufficient.

Most species of cranes are at least threatened, if not seriously endangered, within their range. The plight of the Whooping Cranes of North America inspired some of the first US legislation to defend endangered species.

They are opportunistic feeders that modify their diet according to the season and their own nutrient requirements. They eat a variety of items from suitably sized small rodents, fish, amphibians, and insects, to grain, berries, and plants.

There are representatives of this collection on all the continents except Antarctica and South America.

The cranes' beauty and their stunning mating dances have made them highly symbolic birds in numerous cultures with records dating back to ancient times. Crane mythology is widely spread and can be found in areas such as the Aegean, South Arabia, Japan and in the Native American cultures of North America. In northern Hokkaido, the women of the Ainu people, whose society is more Siberian than Japanese, performed a crane bop that was captured in 1908 in a photograph by Arnold Genthe. In Korea, a crane dance has been performed in the courtyard of the Tongdosa Temple because the Silla Dynasty (646 CE).

In Mecca, in pre-Islamic South Arabia, the goddesses Allat, Uzza, and Manah, who were supposed to be daughters of and intercessors with Allah, were called the "three exalted cranes" (gharaniq, an incomprehensible word on which 'crane' is the usual gloss).

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.

Lease bond

It is a bond created among three parties; the land lord, the tenant and the surety the underwriter. It creates a contract among all these parties to have a proper link.

This bond is issued to landlord in connection to cash security deposit, letter of credit, personal or corporate guarantee which serves as a security for the purpose of tenant’s full and complete performance of the terms and condition of commercial lease. This bond is similar in many aspects, both letter of credit and guarantee. In failure of the bond, the landlord submits the bond against a claim, which is paid by the surety underwriter as per the terms and condition of the lease. The landlord draws the lease money from the bank under a letter of credit.

In this bond, the surety underwriter is liable to the landlord and not the tenant for breach of the lease contract. The surety underwriter's responsibility on the lease bond is strictly monetary; the surety underwriter is generally not required to perform the unfulfilled non-monetary obligations of the tenant.

Industry

An industry is generally any grouping of businesses that share a common method of generating profits, such as the music industry, the automobile industry, or the cattle industry. It is also used specifically to refer to an area of economic production focused on manufacturing which involves large amounts of capital investment before any profit can be realized, also called "heavy industry.As-of 2004, Financial services is the largest industry or category of industries in the world in terms of earnings.

Industry in the second sense became a key sector of production in European and North American countries during the Industrial Revolution, which upset previous mercantile and feudal economies through many successive rapid advances in technology, such as the development of steam engines, power looms, and advances in large scale steel and coal production. Industrial countries then assumed a capitalist economic policy. Railroads and steam-powered ships began speedily integrating previously impossibly-distant world markets, enabling private companies to develop to then-unheard of size and wealth. Manufacturing is a wealth-producing sector of an economy. Other sectors such as the service sector tend to be wealth consuming sectors. Following the Industrial Revolution, perhaps a third of the world's economic output is derived from manufacturing industries—more than agriculture's share.

Pitch

In music, pitch is the psychological associate of the fundamental frequency of a note. The note an above middle C played on any instrument is perceived to be of the same pitch as a pure tone of 440 Hz, but does not essentially contain a partial having that frequency. Furthermore, a slight change in frequency need not lead to a perceived change in pitch, but a change in pitch implies a change in frequency. In fact, the just perceptible difference is about five cents, but varies over the range of hearing and is more precise when the two pitches are played at the same time. Like other human stimuli, the perception of pitch also can be explained by the Weber-Fechner law.

Pitch also depends on the amplitude of the sound, especially at low frequencies. For instance, a low bass note will sound lower in pitch if it is louder. Like other senses, the comparative perception of pitch can be fooled, resulting in "audio illusions". There are several of these, such as the tritone paradox, but most especially the Shepard scale, where a continuous or discrete sequence of specially formed tones can be made to sound as if the sequence continues ascending or descending forever.

Ku Klux Klan

Ku Klux Klan (KKK) is a name given to the fraternal organizations in the United States which has advocated the white supremacy, anti-Semitism, racism, anti-Catholicism, and nativism consisting of members both in the past as well as the future. The life of Klan's first started on 1866 and was linked directly to the Democratic Party. Founded by veterans of the Confederate Army, its main purpose was to resist Reconstruction, and it focused as much on intimidating "carpetbaggers" and "scalawags" as on putting down the freed slaves.

Lahar

A lahar is a type of mudflow composed of pyroclastic material and water that flows down from a volcano, typically along a river valley. The term 'lahar' originated in Indonesia.Lahars have the consistency of concrete: wet when moving, then solid when stopped. Lahars can be huge: the Osceola lahar produced 5,600 years ago by Mount Rainier in Washington produced a wall of mud 180 m (600 feet) deep in the White River canyon and extends over an area of over 320 km².

Lahars can be extremely dangerous, because of their energy and speed: large lahars can flow several tens of meters per second, and can flow for many kilometres, causing catastrophic destruction along the way. The lahars from the Nevado del Ruiz eruption in Colombia in 1985 killed an estimated 25,000 people in the city of Armero who were buried under 8 m (26 ft) of mud and debris. The 1953 Tangiwai disaster in New Zealand was caused by a lahar.

Lahars have several possible causes:

Snow and glaciers can be melted by a pyroclastic flow during an eruption
A flood caused by a glacier, lake breakout, or heavy rainfall can release a lahar, also called glacier run or jökulhlaup.
