Market
In economics a financial market is a device that allows people to easily buy and sell financial securities, commodities, and other fungible substance of value at low transaction costs and at prices that reflect capable markets. A stock market is a market for the trading of company stock, and derivatives of same; both of these are securities scheduled on a stock replace as well as those only traded privately.

Resistance
The resistance of an object determines the amount of current through the object for a known voltage across the object I=V/R, where R is the resistance of the object, measured in ohms, equivalent to J•s/C2, V is the voltage across the object, measured in volts, I is the current through the object, measured in amperes. In metals, the Fermi level lies in the conduction band giving rise to free transfer electrons. However, in semiconductors the position of the fermi level is within the band gap, closely half way between the conduction band minimum and valence band maximum for intrinsic semiconductors.

Security
The word security in general procedure is synonymous with safety, but as a technical term security means that something not only is protected but that it has been secured. A condition that results from the establishment and maintenance of protective measures that ensures a state of inviolability from hostile acts or influences. With respect to classified matter, the condition that prevents unauthorized persons from having right to use to official information that is safeguarded in the benefit of national security.

Computer file
In most computer files are stored on various type of data storage device, there is a hard disk, from which most operating systems run and on which most store their files. Hard discs are the most ever-present form of non-volatile storage at the start of the 21st century. Where files have only temporary information, they may be stored in RAM. The way a computer organizes, names stores and manipulates files is worldwide referred to as its file system. Nearly all computers have at least one file system.

Vehicles
Vehicles are non-living means of moving. They are most repeatedly man-made (e.g. bicycles, cars, motorcycles, trains, ships, and aircraft), although some other means of transportation which are not made by man can also be called vehicles; examples include icebergs and balanced tree trunks. Vehicles may be propelled by animals, e.g. a chariot or an ox-cart. However, animals on their own, though used as a earnings of transportation, are not called vehicles. This includes humans transport another human, for example a child or a disabled person.
Vehicles that do not pass through on land are often called crafts, such as watercraft, sail craft, aircraft, hovercraft and spacecraft. Movement lacking the help of a vehicle or an animal is called locomotion. The word vehicle itself comes from the Latin vehicular.

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.

Anatomical basics of the human lip
The skin of the lip, with three to five cellular layers, is very thin compared to typical face skin, having up to 16 layers. With light skin color, the lip skin contains no melanocyte. Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. With darker skin color this effect is less prominent, as in this case the skin of the lips contains more melanin and thus is visually thicker.
The lip skin is not hairy and does not have sweat glands or sebaceous glands. Therefore, it does not have the usual protection layer of sweat and body oils which keep the skin smooth, kill pathogens, and regulate warmth. For these reasons, the lips dry out faster and become chapped more easily.

flag
The first flags were used to assist military coordination on battlefields and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is similarly challenging (such as the maritime environment where semaphore is used). National flags are potent patriotic symbols with varied wide-ranging interpretations, often including strong military associations due to their original and ongoing military uses. Flags are used in messaging, advertising, or for other decorative purposes, though at this less formal end the distinction between a flag and a simple cloth banner is blurred. The study of flags is known as vexillology, from the Latin vexillum meaning flag or banner.

Morality
One counter-argument is that because the government is the party performing the act of imposing taxes, and assuming the existence of a democracy, society as a whole decides how the tax system should be organised. The American Revolution's "No taxation without representation" slogan implied this view. The same argument could be made in a monarchy: "since the King embodies the nation, the nation as a whole decides how the tax system should be organised." Substituting the terms "Politburo," "Führer," or "Leader," etc., for the word "King," one can describe the politics of most of the 20th century. Under this view, taxes are paid individually and therefore, to be considered voluntary, in any meaningful way, should be levied only with the consent of the individual.

Bankruptcy
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.

Personal property
The distinction between these kinds of property is important for a variety of reasons. Generally one's rights on movables are more attenuated than one's rights on immovable. The statutes of restrictions or prescriptive periods are usually shorter when trading with personal or movable property. Real property rights are usually enforceable for a longer period and in most jurisdictions real estate and immovable are registered in government sanctioned land registers. In some jurisdictions, rights can be registered against personal or movable property.

An Automobile
The automobile powered by the Otto gasoline engine was invented in Germany by Karl Benz in 1885. Benz was granted a patent dated 29 January 1886 in Mannheim for that automobile. Even though Benz is credited with the invention of the modern automobile, several other German engineers worked on building automobiles at the same time. In 1886, Gottlieb Daimler and Wilhelm Maybach in Stuttgart patented the first motor bike, built and tested in 1885, and in 1886 they built a converted horse-drawn stagecoach. In 1870, German-Austrian inventor Siegfried Marcus assembled a motorized handcart, though Marcus vehicle did not go beyond the experimental stage.

Chimpanzee
Anatomical differences between ordinary and Pygmy Chimpanzees are slight, but in sexual and social behavior there are marked differences. Common Chimpanzees have an omnivorous diet, a troop hunting society based on beta males led by a relatively weak alpha, and highly compound social relationships; Bonobos, on the other hand, have a typically herbivorous diet and an egalitarian, matriarchal, sexually accessible behavior. The showing skin of the face, hands and feet varies from pink to very dark in both species, but is usually lighter in younger individuals, darkening as maturity is reached. Bonobos have longer arms and tend to walk upright more often than the Common Chimpanzee.
Africans have had contact with chimpanzees for millennia. The primary recorded contact of Europeans with chimps took rest in present-day Angola during the 1600s. The record of Portuguese explorer Duarte Pacheco Pereira (1506), preserved in the Portuguese National Archive (Torre do Tombo), is perhaps the first European document to acknowledge that chimpanzees built their own rudimentary tools.
The first use of the name "chimpanzee", however, did not happen until 1738. The name is derived from a Tshiluba language term "kivili-chimpenze", which is the limited name for the animal and translates insecurely as "mock man" or possibly just "ape". The colloquialism "chimp" was most probable coined some time in the late 1870s. Science would finally take the 'pan' occurring in 'chimpanzee' and attribute it to Pan, a rural ancient Greek god of nature. Biologists would concern Pan as the genus name of the animal. Chimps as well as other apes had also been supposed to have existed in ancient times, but did so largely as myths and legends on the edge of Euro-Arabic societal consciousness, mostly through fragmented and sketchy accounts of European adventurers. Apes are mentioned variously by Aristotle, as healthy as the Bible.

Computer
A computer is a machine for manipulate data according to a list ofcommands known as a program. Computers are tremendously adaptable. Infact, they are universal information-processing machines. According tothe Church–Turing theory, a computer with a positive minimum entrancecapability is in principle capable of performing the responsibilitiesof any other computer. Therefore, computers with capability rangingfrom those of a personal digital supporter to a supercomputer may allachieve the same tasks, as long as time and memory capacity are notconsideration. Therefore, the same computer design may be modified fortasks ranging from doling out company payrolls to controlling unmannedspaceflights. Due to technical progression, modern electroniccomputers are exponentially more capable than those of precedinggenerations. Computers take plentiful physical forms. Early electroniccomputers were the size of a large room, while whole modern embeddedcomputers may be lesser than a deck of playing cards. Even today, hugecomputing conveniences still exist for focused scientific computationand for the transaction processing necessities of large organizations.Smaller computers designed for personage use are called personalcomputers. Along with its convenient equivalent, the laptop computer,the personal computer is the ubiquitous in order processing andcommunication tool, and is typically what is meant by "a computer".However, the most general form of computer in use today is theembedded computer. Embedded computers are usually comparatively simpleand physically small computers used to control one more device. Theymay control equipment from fighter aircraft to industrial robots todigital cameras. in the beginning, the term "computer" referred to aperson who performed numerical calculations, frequently with the aidof a mechanical calculating device or analog computer. In 1801, JosephMarie Jacquard made an improvement to the presented loom designs thatused a series of punched paper cards as a program to weave involvedpatterns. The resulting Jacquard loom is not considered a truecomputer but it was an essential step in the growth of modern digitalcomputers.
Charles Babbage was the first to conceptualize and design a completelyprogrammable computer as early as 1820, In 1801, Joseph Marie Jacquardmade an improvement to the presented loom designs that used a seriesof punched paper cards as a program to weave involved patterns. Theresulting Jacquard loom is not considered a true computer but it wasan essential step in the growth of modern digital computers.
but due to a combination of the restrictions of the technology of thetime, limited finance, and an incapability to resist tinkering withhis design, the device was never really constructed in his lifetime.By the end of the 19th century a number of technologies that wouldlater prove helpful in computing had appeared, out such as the punchcard and the vacuum tube, and large-scale automated data giving usingpunch cards was performed by tabulating equipment designed by HermannHollerith.During the first half of the 20th century, many technicalcomputing wants were met by increasingly difficult special-purposeanalog computers, which used a direct mechanical or electrical modelof the problem as a base for subtraction (they became ever more rareafter the development of the programmable digital computer). Sequenceof gradually more powerful and stretchy computing devices wereconstruct in the 1930s and 1940s.

Dance
Unlike some early human activities such as the production of stone tools, hunting, cave painting, etc., dance does not leave behind physical artifacts for immediate evidence. Thus, it is impossible to say with any certainty when dance became part of human culture. However, dance has certainly been an important part of ceremony, rituals, celebrations and entertainment since the birth of the earliest human civilizations. Archaeology delivers traces of dance from prehistoric times such as gyptian tomb paintings depicting dancing figures from circa 3300 BC and the Bhimbetka rock-shelter paintings in India.

Guildo Loves You All
Guildo Hat Euch Lieb! In English said as "Guildo Loves You All!” is a German entry in the Eurovision Song Contest 1998, performed in German by Guildo Horn & Die Orthopädischen Strumpet. At the close of voting, it had received 86 points, placing 7th in a field of 25. "Alf Igel" was false name of television host Stefan Raab who wrote this. The song is a tongue-in-cheek parody of the scalier style for which
