River

A river is a natural waterway that transits water through a setting from higher to lower elevations. A river may have its basis in a spring, lake, from damp, boggy landscapes where the soil is waterlogged, from glacial melt, or from surface runoff of precipitation. Almost each and every one river is joined by other rivers and streams termed tributaries the highest of which are known as headwaters. Water may also begin from groundwater sources. Throughout the course of the river, the total volume transported downstream will often be a combination of the free water flow together with a important contribution flowing through sub-surface rocks and gravels that underlie the river and its floodplain. For many rivers in large valleys, this unseen component of flow may greatly go above the visible flow.

From their source, all rivers flow downhill, typically terminating in the sea or in a lake, through a confluence. In arid areas rivers sometimes end by losing water to desertion. River water may also infiltrate into the soil or pervious rock, where it becomes groundwater. Excessive abstraction of water for use in commerce, irrigation, etc., can also cause a river to dry before success its natural terminus.

Human interrelationship

Although humans currently comprise only about one-half of one percent of the total living biomass on Earth, the human effect on nature is disproportionately large. Because of the extent of human influence, the boundaries between what we regard as nature and "made environments" is not clear cut except at the extremes. Even at the extremes, the amount of natural environment that is free of discernible human influence is presently diminishing at an increasingly rapid pace, or, according to some, has already disappeared.

The development of technology by the human race has allowed the greater exploitation of natural resources and has helped to alleviate some of the risk from natural hazards. In spite of this progress, however, the fate of human civilization remains closely linked to changes in the environment. There exists a highly complex feedback-loop between the use of advanced technology and changes to the environment that are only slowly becoming understood. Manmade threats to the Earth's natural environment include pollution, deforestation, and disasters such as oil spills. Humans have contributed to the extinction of many plants and animals.

Market

A market is a social arrangement that allows buyers and sellers to discover in sequence and carry out a voluntary replace of goods or services. It is one of the two key institutions that organize trade, along with the right to own goods. In everyday usage, the word market may refer to the place where goods are traded, sometimes known as a marketplace, or to a street 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.

Ethnic diversity

The Affirmative action can be defined as action taken to compensate for past unfairness in the education of minorities. The present system of affirmative action allows universities to admit applicants from certain ethnic and minority groups with lower credentials. The main aim of affirmative action is to produce a diverse campus population that is comparable to today's society. The use of race as a main factor by which someone is admitted to college in the long run will compromise the quality of the university. By Implicating affirmative action to solve the problem of diversity on today's campuses has lead to the creation of problems.

The discrimination which is against Caucasian and Asian American students a long with the toleration of lower quality work produced by African American students and other minority students is an example of the problems caused by the Affirmative Action. Though the affirmative action intends to do good, which lowers the standards by which certain racial groups are admitted to college is not the way to solve the problem of diversity in America's universities. The present condition of America's public schools is directly responsible for the poor academic achievement of minority children.

Amusement park

Amusement park is the general word for a collection of rides and other leisure attractions assembled for the purpose of enjoyable a reasonably large group of people. An amusement park is more involved than a simple city park or playground, as an amusement park is intended to cater to adults, teenagers, and small children. An amusement park may be stable or temporary, generally periodic, such as a few days or weeks per year. The short-term amusement park with mobile rides etc. is called a funfair or carnival.

Theme parks form a more closely defined type of an amusement park. They are permanent conveniences that use architecture, signage, landscaping to help express the feeling that people are in a different place or time. Often a theme park will have a variety of 'lands' of the park committed to telling a particular story. Otherwise, an amusement park often has rides with tiny in terms of theming design elements. The main difference among a theme park and an amusement park is to in a theme park all the rides go all with the theme of the park, for example Disney World.

Computer file

A computer file is a block of subjective information, or resource for storing information, that is available to a computer program and is usually based on some kind of durable storage. A file is durable in the intelligence that it remains available for programs to use after the current program has finished. Computer files can be considered as the up to date counterpart of paper documents which traditionally were kept in offices and libraries files.
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.

FLAG

A FLAG is a piece of woven cloth, often flown from a pole or mast, generally used symbolically for signalling or recognition. The term FLAG is also used to refer to the graphic intend employed by a flag, or to its picture in another medium.
The first flags were used to assist military organization on battlefields and flags have evolved into a general tool for rudimentary signalling and identification, mainly 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 interpretation, often including strong military associations due to their unique and ongoing military uses. Flags are used in messaging, advertising, or for other decorative purpose, though at this less formal end the difference 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 poster.

Intranet

An intranet is a private computer network that uses Internet protocols, network connectivity to securely divide part of an organization's information or operations with its employees. Sometimes the term refers only to the most perceptible service, the internal website. The same concepts and technologies of the Internet such as clients and servers running on the Internet protocol suite are used to make an intranet. HTTP and other Internet protocols are commonly used as well, such as FTP. There is often a challenge to use Internet technologies to provide new interfaces with corporate legacy data and information systems.
Intranets can help users to locate and view information faster and use applications related to their roles and responsibilities. With the help of a web browser interface such as Internet Explorer or Firefox, users can contact data held in any database the organization wants to make available, anytime and - subject to security provisions - from anywhere within the company workstations, increasing employees' capability to perform their jobs faster, more accurately, and with confidence that they have the right information. It also helps to improve the services provided to the users.
With intranets, organizations can make more information accessible to employees on a "pull" source rather than being deluged indiscriminately by emails.
Intranets can serve as influential tools for communication within an organization, vertically and horizontally. From a communications standpoint, intranets are useful to communicate strategic initiatives that have a worldwide reach throughout the organization. The type of information that can easily be conveyed is the reason of the initiative and what the initiative is aiming to achieve, who is driving the initiative, results achieved to date, and who to speak to for more information.

laptop

A laptop computer, or simply laptop, is a small mobile computer, which usually weighs 2-18 pounds (1-6 kilograms), depending on mass, materials, and other factors. 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.
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.

Mobile phone

A mobile telephone or cellular telephone is a long-range, portable electronic machine used for mobile communication. In addition to the normal voice function of a telephone, current mobile phones can carry many additional services such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and getting photos and video. Most current mobile phones connect to a cellular network of bottom stations, which is in turn interconnected to the public switched telephone network.
Mobile news services are increasing with many organizations providing on-demand news armed forces by SMS. Some also provide instant news pushed out by SMS. Mobile telephony also facilitates activism and public journalism being explored by Reuters and Yahoo and small sovereign news companies such as Jasmine News in Sri Lanka. Also companies like Monster are starting to offer mobile services such as job search and career information.
The total worth of mobile data services exceeds the value of paid services on the internet, and was worth 31 B dollars in 2006. The largest categories of mobile services are music, picture downloads, video gaming, adult entertainment, gambling, video/TV.

Table

In relational databases, SQL databases, and flat file databases, a table is a set of data elements that is controlled using a model of horizontal rows and vertical columns. The columns are identified by name, and the rows are identified by the values appearing in a particular column division which has been identified as a candidate key. Table is another term for family although there is the difference in that a table is usually a multi-set of rows whereas a relation is a set and does not allow duplicates. A table has a particular number of columns but can have any number of rows. Besides the actual data rows, tables generally have related with them some meta-information, such as constraints on the table or on the values within particular columns.
The data in a table does not have to be actually stored in the database. Views are also relational tables, but their data is considered at query time. In non-relational systems, such as hierarchical databases, the isolated counterpart of a table is a structured file, representing the rows of a table in each record of the file and each column in a record.

Software

Software, consisting of programs, enables a computer to perform specific tasks, as opposed to its physical components which can only do the responsibilities they are mechanically designed for. The term includes application software such as word processors which perform helpful tasks for users, system software such as operating systems, which interface with hardware to run the necessary services for user-interfaces and applications, and middleware which controls and co-ordinates distributed system.
Computer software has to be loaded into the computer's storage space ( memory or RAM). Once the software is loaded, the computer is able to implement the software. Computers control by executing the computer program. This involves passing instructions from the application software, through the system software, to the hardware which finally receives the instruction as machine code. Each instruction causes the computer to carry out an operation moving data, transport out a computation, or altering the control flow of instructions.

Power

Power is the rate at which work is performed or energy is transmitted or the amount of energy essential or finished for a given unit of time. It is many types of conversion Power.Power (physics) is the quantity of work done or energy transferred per unit of time. Motive power is power which moves great, such as output of a motor. Electric power generation is the process of converting any form of energy to electrical energy.

Power station, a capability for generating electricity, nuclear power, the conversion of nuclear force to electricity, solar power, the translation of solar energy to electricity, wind power, the conversion of wind energy to electricity, wave power, the conversion of signal energy to electricity, tidal power, the conversion of energy of the tides energy to electricity, geothermal power, the conversion of geothermal power to electricity, hydropower, the conversion of possible or kinetic energy of water to electricity, Optical power of a lens is the opposite of its focal length, Effective radiated power in radio telecommunications is a calculate of radio station antennas

Reactance

Reactance is the invented part of electrical impedance, a measure of opposition to a sinusoidal alternating current. Reactance arises from the occurrence of inductance and capacitance within a circuit, and the SI unit is the ohm. The value of the reactance is a lower maximum value on the amount of the impedance. A positive reactance implies that the phase of the voltage leads the phase of the current, while a harmful reactance implies that the phase of the voltage lags the phase of the current. A reactance of zero implies the current and voltage are in phase and equally if the reactance is non-zero then there is a phase distinction between the voltage and current

Safety

Safety is the state of being safe, the situation of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or additional types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. 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.

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

Elevator

An elevator is a transport tool used to move goods or people up and down. Outside North America, elevators are known most commonly as lifts. Other languages may have loanwords based on moreover elevator or lift .Because of wheelchair right to use laws, elevators are often a requirement in new buildings with multiple floors.Elevators start on as simple rope or chain hoists.

An elevator is basically a platform that is either pulled or pushed up by mechanical resources. A modern day elevator consists of a cab mounted on a platform within an together with this space called a shaft, or in Commonwealth English called a hoist way. In the past, elevator drive mechanisms were mechanical by steam and water hydraulic pistons. In a traction elevator, cars are pulled up by means of rolling steel ropes over an extremely grooved pulley, frequently called a sheave in the industry. The weight of the car is intention with a counterweight. Sometimes two elevators move forever synchronized in opposite way, and they are each other's counterweight.

Computer

A computer is a machine for manipulating data according to a list of instructions.Computers take plentiful physical forms. 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.
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.

Honey

Honey is a sweet and thick fluid produced by honey bees from the nectar of flowers. According to the United States National Honey Board and various international food system, honey stipulates a pure product that does not allow for the addition of any other substance...this includes, but is not limited to, water or other sweeteners. This article refers exclusively to the honey produced by honey bees honey twisted by other bees or other insect have very different properties. Honey is significantly sweeter than table sugar and has attractive chemical properties for baking. Honey has a typical flavor which leads some people to prefer it over sugar and other sweeteners.

Most microorganisms do not grow in honey because of its low water movement of 0.6[2]. However, it is important to note that honey frequently contains dormant end spores of the bacteria Clostridium outline, which can be perilous to infants as the end spores can transform into toxin-producing bacteria in the infant's immature intestinal tract, leading to disease and even death. The study of pollens and spores in raw honey can determine floral sources of honey. Because bees carry an electrostatic charge, and can attract other particles, the same techniques of melissopalynology can be used in area ecological studies of radioactive particles, sand, or particulate pollution.

Toy

A Toy is an item used in play. Toys are usually related with children and pets, but it is not unusual for adult humans and some non-domesticated animals to play with toys. Many items are manufactured to serve as toys, but items shaped for other purpose can also be used as toys. A child may pick up a domestic item and 'fly' it around pretending that it is an airplane, or an animal might play with a pinecone by batting at it, chasing it, and throwing it up in the air. Some toys are intended largely as collector's items and are not to be played with.The origin of toys is prehistoric; dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are pleasure found at archaeological sites. The origin of the word toy is unknown, but it is understood that it was first used in the 14th century.

Toys and play in general are an important part of the method of learning about the world and growing up. The young use toys and play to discover their identity, help their bodies grow tough, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults use toys and play to form and strengthen social bonds, teach the young, memorize and reinforce lessons from their own youth, exercise their minds and bodies, practice skills they may not use every day, and decorate their living spaces. Toys are more than simple amusement, and they and the way they are used greatly influence most aspects of life.

Russian Ground Forces

The Russian Ground Forces are the land forces of the Russian Federation, formed from parts of the collapsing Soviet Army in 1992. While the Russian Ground Forces in their present form are only fourteen years old, Russian officials trace their antecedents' history during the Imperial Russian era back to the time of Kievan Rus. Since 1992 the Ground Forces have had to withdraw thousands of troops from former Soviet garrisons abroad, while being extensively committed to the Chechen wars and peacekeeping and other operations in the Soviet successor states.

Since 1991 inability to allow the new strategic circumstances, a crippling lack of funds, and the wasting away of the Russian people's belief in the Armed Forces have led to a steady decline in forces capacity. Professionalisation is now steadily taking place, but there is little hope for a rapid grows in effectiveness. Alexander Golts, a long-time Russian military columnist, describes the problems: "Since 1999 the defense budget has grown more than three times—rising from 109 billion rubles to 346 billion. However, no encouraging changes have come about: the level of combat readiness and discipline is just as low as it was few years ago.

duck

Duck is the common name for a number of species in the Anatidae family of birds. The ducks are divided between several subfamilies listed in full in the Anatidae article. Ducks are mostly aquatic birds, mostly smaller than their relatives the swans and geese, and may be found in both fresh water and sea water.
Most ducks have a wide flat beak adapted for dredging. They exploit a variety of food sources such as grasses, aquatic plants, fish, insects, small amphibians[1], worms, and small molluscs. Diving ducks and sea ducks forage deep underwater; Dabbling ducks feed on the surface of water or on land. Dabbling ducks have in their beaks special plates called lamellae[1] similar to a whale's baleen. These tiny rows of plates along the inside of the beak let them filter water out of the side of their beaks and keep food inside. To be able to submerge more easily, the diving ducks are heavier than dabbling ducks, and therefore have more difficulty taking off to fly. A few specialized species such as the Smew, Goosander, and the mergansers are adapted to catch large fish.
The males (drakes) of northern species often have extravagant plumage, but that is moulted in summer to give a more female-like appearance, the "eclipse" plumage. Southern resident species typically show less sexual dimorphism. Many species of ducks are temporarily flightless while moulting; they seek out protected habitat with good food supplies during this period. This moult typically precedes migration.

radar

Radar (Radio Detection And Ranging) detects things at a distance by bouncing radio waves off them. The delay caused by the echo measures the distance. The direction of the beam determines the direction of the reflection. The polarization and frequency of the return can sense the type of surface. Navigational radars scan a wide area two to four times per minute. They use very short waves that reflect from earth and stone. They are common on commercial ships and long-distance commercial aircraft
General purpose radars generally use navigational radar frequencies, but modulate and polarize the pulse so the receiver can determine the type of surface of the reflector. The best general-purpose radars distinguish the rain of heavy storms, as well as land and vehicles. Some can superimpose sonar data and map data from GPS position.
Search radars scan a wide area with pulses of short radio waves. They usually scan the area two to four times a minute. Sometimes search radars use the doppler effect to separate moving vehicles from clutter. Targeting radars use the same principle as search radar but scan a much smaller area far more often, usually several times a second or more. Weather radars resemble search radars, but use radio waves with circular polarization and a wavelength to reflect from water droplets. Some weather radar use the doppler to measure wind speeds

Audio

AM broadcast radio sends music and voice in the Medium Frequency (MF—0.300 MHz to 3 MHz) radio spectrum. AM radio uses amplitude modulation, in which the amplitude of the transmitted signal is made proportional to the sound amplitude captured (transduced) by the microphone while the transmitted frequency remains unchanged. Transmissions are affected by static and interference because lightning and other sources of radio that are transmitting at the same frequency add their amplitudes to the original transmitted amplitude. The most wattage an AM radio station is allowed to use is 50,000 watts and the only stations that can blast out signals this high were grandfathered in; these include WJR and CKLW.
FM broadcast radio sends music and voice with higher fidelity than AM radio. In frequency modulation, amplitude variation at the microphone cause the transmitter frequency to fluctuate. Because the audio signal modulates the frequency and not the amplitude, an FM signal is not subject to static and interference in the same way as AM signals. FM is transmitted in the Very High Frequency (VHF—30 MHz to 300 MHz) radio spectrum. VHF radio waves act more like light, traveling in straight lines, hence the reception range is generally limited to about 50-100 miles. During unusual upper atmospheric conditions, FM signals are occasionally reflected back towards the Earth by the ionosphere, resulting in Long distance FM reception. FM receivers are subject to the capture effect, which causes the radio to only receive the strongest signal when multiple signals appear on the same frequency. FM receivers are relatively immune to lightning and spark interference.

Commercial mortgage

A commercial mortgage is a loan made using real estate as collateral to protecting repayment. Commercial mortgage is similar to a residential mortgage, except the collateral is a commercial building or other business real estate, not residential property.

In calculation, commercial mortgages are usually taken on by businesses as a substitute of individual borrowers. The borrower may be a partnership, incorporated business, or limited company, so assessment of the creditworthiness of the business can be more complicated than is the case with residential mortgages.

Commercial mortgages are typically non recourse i.e. that in the event of default in repayment, the creditor can only seize the collateral, but has no further claim against the borrower for any remaining deficiency. Less commonly, the mortgage is complement by a general obligation of the borrower, which makes the debt payable in full even if foreclosure on the mortgaged collateral does not satisfy the outstanding balance.

Trustworthiness

Trustworthiness is a value considered to be a Virtue. A trustworthy person is someone in whom we can place our trust and rest secured that the trust will not be deceived.

A person can prove his trustworthiness by satisfying an assigned responsibility - and as an expansion of that, to not let down our expectations. The responsibility can be either material, such as delivering a mail package on time, or it can be a non-material such as keeping an important secret to him.

History of the People's Republic of China

The Chinese Civil War ended in 1949 with the Communist Party of China in control of the mainland, and the Kuomintang retreating to Taiwan and some outlying islands of Fujian. On October 1, 1949 Mao Zedong proclaimed the People's Republic of China, declaring "the Chinese people have stood up."

Following a series of dramatic economic failures, like the famous Great Leap Forward, Mao stepped down from his position as chairman in 1959, with Liu Shaoqi, nominated by the National People's Congress, as successor. Mao still had a huge influence over the Party, but was removed from day-to-day management of economic affairs, which came under the control of a more reasonable leadership consisting of Liu Shaoqi, Deng Xiaoping, and others who initiated economic reforms.
