Sports   Fri Jun 27, 2008 6:42
Sport is an activity to facilitate is governed by a set of rules or customs and frequently engaged in competitively. Used by itself, sports generally refer to activities where the physical capabilities of the participant are the sole or primary determiner of the outcome, but the term is also used to comprise activities such as mind sports and motor sports where psychological acuity or equipment quality are major factors. Sports are used as hobby for the player and the viewer. It has also proved by experiments that daily exercise would boost mental strength and power to study.

Sports have been ever more organized and keeping pace from the time of the Ancient Olympics up to the present century. Industrialization has brought improved leisure time to the citizens of developed and developing countries, leading to more time for people to be present at and follow spectator sports, greater contribution in athletic activities, and increased accessibility. These trends continued with the beginning of mass media and global statement.

Weather   Tue Jun 17, 2008 7:49
Weather most frequently results from temperature differences from one planet to another. On large scales, temperatures differences arise mainly as areas closer to Earth's equator get more energy per unit area from the Sun than do regions nearer to Earth's poles. On local scales, temperature differences can arise because different surfaces have opposed physical characteristics such as reflectivity, roughness, or moisture content.

Surface temperature differences in roll cause pressure differences. A hot surface heats the air over it and the air expands, lowering the air pressure. The resulting parallel pressure rise accelerates the air from high to low pressure, creating wind, and Earth's rotation then causes curvature of the pour via the Coriolis Effect. The strong temperature contrast among polar and tropical air gives rise to the jet flow. Most weather systems in the mid-latitudes are caused by instabilities of the jet stream flow. Weather systems in the tropics are caused by different processes, such as monsoons shower systems.

Earth   Thu May 29, 2008 15:15
Earth is the fifth largest planet in the solar system, third in order of distance from the Sun. It is the largest of its planetary system's terrestrial planets and the only place in the universe known to support life.

The most prominent features of the earth's climate are its two large polar regions, two relatively narrow temperate zones, and a wide equatorial tropical to subtropical region. Precipitation patterns vary widely according to location, ranging from several meters of water per year to less than a millimeter. About 70 percent of the surface is covered by salt-water oceans. The remainder consists of continents and islands, with the vast majority of the inhabited land in the Northern Hemisphere.

Earth has evolved through geological and biological processes that have left traces of the original conditions. The outer surface is divided into several tectonic plates that gradually migrate across the surface over geologic time spans, which at least several times have changed relatively quickly. The interior of the planet remains active, with a thick layer of molten Earth mantle and an iron-filled core that generates a magnetic field

Yoga   Tue May 27, 2008 9:10
Yoga is one of the six schools of Hindu philosophy, focusing on meditation as a trail to self-knowledge and freedom. Yoga is seen as a means to mutually physiological and spiritual mastery. Outside India, Yoga has become mainly related with the practice of asanas of Hatha Yoga, although it has influenced the whole dharmic religions family and other spiritual practices throughout the world.

5,000 year old carvings from the Indus Valley Civilization represent a figure that archaeologists think represents a yogi sitting in meditation posture. The sitting in a conventional cross-legged yoga pose with its hands resting on its knees. The explorer of the seal, archaeologist Sir John Marshall, named the figure Shiva Pashupati. A seal from the Indus Valley Civilization, The first known written reference to yoga is in the Rig Veda, likely by the western scholars to be at least 3,500 years old. The Upanishads, Bhagavad-Gita, and the Yoga Sutras of Patanjali also converse the concepts and teachings of yoga.

Pollution   Fri May 16, 2008 6:35
Pollution is the overture of contaminants into an surroundings, of whatsoever prearranged or decided upon proportions or enclose of reference; these contaminants grounds insecurity, confusion, destruction or uneasiness to the physical systems or living organisms therein. Pollution can get the structure of chemical substances, or power, such as sound, temperature, or light energy. Pollutants, the essentials of pollution, can be distant substances or energies, or naturally happening; while naturally happening, they are considered contaminants at what time they go over normal levels. Pollution is frequently classed as point basis or nonpoint source pollution.

Education   Tue May 13, 2008 17:17
Education encompasses teaching and learning specific skills, and also something less tangible but more profound: the imparting of knowledge, positive judgment and well-developed wisdom. Education has as one of its fundamental aspects the imparting of culture from generation to generation. Education mean 'to draw out', are facilitating realization of self-potential and latent talents of an individual. It is an application of pedagogy, a body of theoretical and applied research relating to teaching and learning and draws on many disciplines such as psychology, philosophy, computer science, linguistics, neuroscience, sociology and anthropology.

The education of an individual human begins at birth and continues throughout life. For some, the struggles and triumphs of daily life provide far more instruction than doe’s formal schooling. Family members may have a profound educational effect often more profound than they realize though family teaching may function very informally

Culture   Thu Mar 13, 2008 6:36
Culture generally refers to patterns of human activity and the symbolic structures that give such activities significance and importance. Cultures can be understood as systems of symbols and meanings that even their creators contest, that lack fixed boundaries, constantly in flux, and that interact and compete with one another Different definitions for culture reflect different theoretical bases for understanding, or criteria for evaluating, human activity.

Culture is usually manifested in music, literature, lifestyle, painting and sculpture, theater and film and similar things. Although some people identify it in terms of consumption and consumer goods anthropologists understand "culture" to refer not only to consumption goods, but to the general processes which produce such goods and give them meaning, and to the social relationships and practices in which such objects and processes become embedded. For them the word culture thus includes art, science, as well as moral systems.

Entertainment   Wed Feb 27, 2008 6:53
Entertainment is an occasion, piece, or movement designed to give enjoyment or leisure to an audience. The audience may join in the entertainment passively as in actively as in computer games. The playing of sports and reading of journalism are usually included in entertainment, but these are regularly called activity more specifically, because they involve some energetic participation past mere leisure.

While people have laughing themselves since the beginning of time, the entertainment industry first became a leading force in culture in the 20th century with the development of latest electronic technologies of recording and spreading. Western peoples, tired of serious purposes and gathering massacre, turned to popular culture following the two world wars. The financial basis of this new culture was advertising of free or inexpensive entertainment program. In their peak, television networks were great selling machines which, besides entertaining people, prohibited both commercial and political markets by providing direct access to the group of customers. This "territory" is now in danger by the explosion and segmentation of media and especially by the growing importance of communication by computer which allows the consumer to look for out the informational message as an alternative of having it broadcast to him or her. A new system of world history sees Americans in changeover between a fourth, entertainment-based "society" and a future fifth evolution based on computer communication.

Education System   Wed Dec 26, 2007 5:12
Schooling occurs when group or a society or an individual sets up a curriculum to educate people, usually the young. Schooling can become systematic. Sometimes education systems can be used to promote doctrine or ethics as well as knowledge, and this can lead to abuse of the system.

Life-long or adult education has become extensive in many countries. However, education is still seen by many as something aimed at children, and adult education is often branded as adult learning or ultimate learning.

Adult education takes on several forms, from formal class-based learning to self-directed learning. Lending libraries provide cheap informal access to books and other self-instructional materials. Many adults have also taken advantage of the rise in computer ownership and internet access to further their casual education.

Computer networking   Thu Dec 13, 2007 2:49
Computer networking is the engineering discipline anxious with communication between computer systems. Such communicate systems comprise a computer network and these networks generally involve at least two devices able of being networked with at least one usually being a computer. The devices can be separated by a small number of meters or nearly unlimited distances. Computer networking is sometimes considered a sub-discipline of telecommunications, and sometimes of computer science, information technology and computer engineering. Computer networks rely a lot upon the abstract and practical application of these scientific and engineering disciplines.

A computer network is any set of computers connected to each other. Examples of networks are the Internet, a wide area network that is the largest to always exist, or a little home local area network (LAN) with two computers connected with standard networking cables connecting to a network interface card in each computer.

Mental health   Thu Nov 29, 2007 4:01
Mental health

Mental health is a concept that refers to a human individual's emotional and psychological well-being. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life."

According to the World Health Organization, there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not necessarily an indicator of mental health.

One way to think about mental health is by looking at how effectively and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, maintain satisfying relationships, and lead an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health.

Electronic media   Tue Nov 27, 2007 2:57


In the last century, a revolution in telecommunications has greatly altered communication by providing new media for long distance communication. The first transatlantic two-way radio broadcast occurred in 1906 and led to common communication via analogue and digital media:

• Analog telecommunications include traditional telephony, radio, and TV broadcasts.
• Digital telecommunications allow for computer-mediated communication, telegraphy, and computer networks.

Communications media impact more than the reach of messages. They impact content and customs; for example, Thomas Edison had to discover that hello was the least ambiguous greeting by voice over a distance; previous greetings such as hail tended to be garbled in the transmission. Similarly, the terseness of e-mail and chat rooms produced the need for the emoticon.

Modern communication media now allow for intense long-distance exchanges between larger numbers of people (many-to-many communication via e-mail, Internet forums). On the other hand, many traditional broadcast media and mass media favor one-to-many communication (television, cinema, radio, newspaper, magazines)

Wilderness   Fri Nov 23, 2007 3:29


Wilderness is generally defined as a natural environment on Earth that has not been directly modified by human activity. Ecologists consider wilderness areas to be an integral part of the planet's self-sustaining natural ecosystem (the biosphere).

The word, "wilderness", derives from the notion of wildness; in other words that which is not controllable by humans. The word's etymology is from the Old English wildeornes, which in turn derives from wildeor meaning wild beast (wild + deor = beast, deer). From this point of view, it is the wildness of a place that makes it a wilderness. The mere presence or activity of people does not disqualify an area from being "wilderness." Many ecosystems that are, or have been, inhabited or influenced by activities of people may still be considered "wild." This way of looking at wilderness includes areas within which natural processes operate without very noticeable human interference.

Looked at through the lens of the visual arts, nature and wildness have been important subjects in various epochs of world history. An early tradition of landscape art occurred in the Tang Dynasty (618-907). The tradition of representing nature as it is became one of the aims of Chinese painting and was a significant influence in Asian art. Artists learned to depict mountains and rivers "from the perspective of nature as a whole and on the basis of their understanding of the laws of nature … as if seen through the eyes of a bird." In the 13th century, Shih Erh Chi listed "scenes lacking any places made inaccessible by nature," as one of the 12 things to avoid in painting.

Human interrelationship   Tue Nov 20, 2007 4:54


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.

Ecosystems   Fri Nov 16, 2007 7:29


All forms of life interact with the environment in which they exist, and also with other life forms. In the 20th century this premise gave rise to the concept of ecosystems, which can be defined as any situation where there is interaction between organisms and their environment.

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way. The structure and composition is determined by various environmental factors that are interrelated. Variations of these factors will initiate dynamic modifications to the ecosystem. Some of the more important components are: soil, atmosphere, radiation from the sun, water, and living organisms.

Each living organism has a continual relationship with every other element that makes up its environment. Within the ecosystem, species are connected and dependent upon one another in the food chain, and exchange energy and matter between themselves as well as with their environment.

Microbes   Fri Nov 2, 2007 3:48


The first form of life to develop on the Earth were microbes, and they remained the only form of life on the planet until about a billion years ago when multi-cellular organisms began to appear. Microorganisms are single-celled organisms that are generally smaller than the human eye can see. They include Bacteria, Fungi, Archaea and Protista.

These life forms are found in almost every location on the Earth where there is liquid water, including the interior of rocks within the planet. Their reproduction is both rapid and profuse. The combination of a high mutation rate and a horizontal gene transfer ability makes them highly adaptable, and able to survive in new environments, including outer space. They form an essential part of the planetary ecosystem. However some microorganisms are pathogenic and can post health risk to other organisms.

Evolution   Tue Oct 30, 2007 5:01


Life, as we understand it, is currently only known to exist on the planet Earth. The origin of life is still a poorly understood process, but it is thought to have occurred about 3.9 to 3.5 billion years ago during the hadean or archean eons on a primordial earth that had a substantially different environment than is found at present. These life forms possessed the basic traits of self-replication and inheritable traits. Once life had appeared, the process of evolution by natural selection resulted in the formation of ever-more diverse life forms.

Species that were unable to adapt to the changing environment and competition from other life forms became extinct. However, the fossil record retains evidence of many of these older species. Current fossil and DNA evidence shows that all existing species can trace a continual ancestry back to the first primitive life forms.

The advent of photosynthesis in very basic forms of plant life worldwide allowed the sun's energy to be harvested to create conditions allowing for more complex life. The resultant oxygen accumulated in the atmosphere and gave rise to the ozone layer. The incorporation of smaller cells within larger ones resulted in the development of yet more complex cells called eukaryotes. Cells within colonies became increasingly specialized, resulting in true multicellular organisms. With the ozone layer absorbing harmful ultraviolet radiation, life colonized the surface of Earth.

Life   Thu Oct 25, 2007 5:51


Properties common to terrestrial organisms (plants, animals, fungi, protists, archaea and bacteria) are that they are cellular, carbon-and-water-based with complex organization, having a metabolism, a capacity to grow, respond to stimuli, and reproduce. An entity with these properties is generally considered life. However, not every definition of life considers all of these properties to be essential. Human-made analogs of life may also be considered to be life.

The biosphere is the part of Earth's outer shell -including air, land, surface rocks and water - within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air). Currently the entire Earth contains over 75 billion tons (150 trillion pounds or about 6.8 x 1013 kilograms) of biomass (life), which lives within various environments within the biosphere.

Weather and climate   Fri Oct 19, 2007 5:40


The atmosphere of the Earth serves as a key factor in sustaining the planetary ecosystem. The thin layer of gases that envelops the Earth is held in place by the planet's gravity. Dry air consists of 78% nitrogen, 21% oxygen, 1% argon and other inert gases, carbon dioxide, etc.; but air also contains a variable amount of water vapor. The atmospheric pressure declines steadily with altitude, and has a scale height of about 8 kilometers at the Earth's surface: the height at which the atmospheric pressure has declined by a factor of e (a mathematical constant equal to 2.71...). The ozone layer of the Earth's atmosphere plays an important role in depleting the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.

Terrestrial weather occurs almost exclusively in the lower part of the atmosphere, and serves as a convective system for redistributing heat. Ocean currents are another important factor in determining climate, particularly the major underwater thermohaline circulation which distributes heat energy from the equatorial oceans to the polar regions. These currents help to moderate the differences in temperature between winter and summer in the temperate zones. Also, without the redistributions of heat energy by the ocean currents and atmosphere, the tropics would be much hotter, and the polar regions much colder.

Historical perspective   Mon Oct 15, 2007 5:20


Based on the available evidence, scientists have reconstructed detailed information about the planet's past. Earth is estimated to have formed approximately 4.55 billion years ago out of the solar nebula, along with the Sun and other planets. The moon formed relatively soon afterwards (roughly 20 million years later, or 4.53 billion years ago).

Initially molten, the outer layer of the planet cooled, resulting in the solid crust. Outgas sing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered by comets, produced the oceans. The highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago.

Continents formed, then broke up and re-formed as the surface of Earth reshaped itself over the course of hundreds of millions of years, occasionally combining to make a super continent. Roughly 750 million years ago, the earliest known super continent Rodinia, began to break apart. The continents later recombined to form Pannotia which broke apart about 540 million years ago, then finally Pangaea, which broke apart about 180 million years ago.

Animals   Wed Oct 3, 2007 5:04


Animals are a major group of generally motile, multicellular organisms that feed by consuming material from other living things. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on.

The word "animal" comes from the Latin word animal, of which animalia is the plural, and is derived from anima, meaning vital breath or soul. In everyday colloquial usage, the word usually refers to non-human animals. The biological definition of the word refers to all members of the Kingdom Animalia. Therefore, when the word "animal" is used in a biological context, humans are included.

Web development   Wed Sep 26, 2007 7:32


Web development is a broad term for any activities related to developing a web site for the World Wide Web or an intranet. This can include e-commerce business development, web design, web content development, client-side/server-side coding, and web server configuration. However, among web professionals, "web development" usually refers only to the non-design aspects of building web sites, e.g. writing markup and coding. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.

For larger businesses and organizations, web development teams can consist of hundreds of people. Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or Information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.

Human heart Structure   Mon Sep 3, 2007 9:23
Human heart Structure

In the human body, the heart is usually situated to the left of the middle of the thorax, underneath the breastbone. The heart is usually felt to be on the left side since the left heart is stronger. The left lung is smaller than the right lung because the heart occupies more of the left hemithorax. The heart is enclosed by a sac known as the pericardium and is surrounded by the lungs. The pericardium is a double membrane structure contains a serous fluid to reduce friction during heart contractions. The mediastinum, a part of the thoracic cavity, is the name of the heart cavity.

The apex is the blunt point situated in an inferior direction. A stethoscope can be placed directly over the apex so that the beats can be counted. It is located posterior to the 5th intercostal space in the left mid-clavicular line. In normal adults, the mass of the heart is 250-350g, or about three fourths the size of a clenched fist, but extremely diseased hearts can be up to 1000 g in mass due to hypertrophy. It consists of four chambers, the two upper atria and the two lower ventricles. On the left is a picture of a fresh human heart which was detached from a 64-year-old British male.

Function of Human heart

The purpose of the right side of the heart is to collect de-oxygenated blood, in the right atrium, from the body and pump it, via the right ventricle, into the lungs so that carbon dioxide can be dropped off and oxygen picked up. This happens through a passive process called diffusion. The left side collects oxygenated blood from the lungs into the left atrium. Beginning the left atrium the blood moves to the left ventricle which pumps it out to the body. On both sides, the lower ventricles are thicker and stronger than the upper atria. The muscle wall surrounding the left ventricle is thicker than the wall surrounding the right ventricle due to the higher force needed to pump the blood through the systemic circulation.

Starting in the right atrium, the blood flows through the tricuspid valve to the right ventricle. Here it is pumped out the pulmonary semilunar valve and travels through the pulmonary artery to the lungs. From there, blood flows back through the pulmonary vein to the left atrium. It subsequently travels through the bicuspid valve to the left ventricle and on to through the aortic semilunar valve to the aorta. The aorta forks and the blood are alienated between key arteries which supply the upper and lower carcass. The blood travels the arteries to the lesser arterioles, then finally to the tiny capillaries which feed all cell. The deoxygenated blood then travels to the venules, which coalesce into veins, then to the inferior and greater vena cavae and finally back to the right entrance hall where the process began.

The heart is well a syncytium, a meshwork of cardiac muscle cells interconnected by contiguous cytoplasmic bridges. This relates to electrical stimulation of one cell spreading to next-door cells.

Fanta   Mon Aug 27, 2007 8:23
Fanta

Fanta is a brand of fruit-flavored soft drink from the Coca-Cola Company, introduced for the first time in Germany in 1940.

Fanta was devise during World War II in Nazi Germany by the German Coca Cola (GmbH) bottling companionship. Due to limits on shipping flanked by Nazi Germany and the United States during hostilities, the German bottling plant could no longer get Coca Cola syrup. The chief executive of the plant, Max Keith, needed to do impressive to keep the plant in operation and came up with a fruit flavor drink made from whatever he could find. Using apple fiber left over from cider presses and whey, a byproduct from cheese construct, Fanta was created and became quite popular. The original German Fanta had a fair-haired color and a different flavor from that of Fanta Orange; the exact flavor varied all through the war, depending on the ease of use of ingredient.

The name 'Fanta' came during an employee contest to name the new beverage. Keith told them to let their Fantasie (German for imagination) run wild. On hearing that, salesman Joe Knipp spontaneously arrived upon the name Fanta.

Older Fanta Logo

After World War II, Fanta was introducing to the United States by Coca-Cola, and in 1960 they bought the trademark. Fanta Orange is the most popular Fanta flavor, available in 180 countries. In terms of volume, Brazil is the largest consumer of Fanta in the world. Fanta remains more popular in Europe and South America than in the United States.

There are over 70 flavors world-wide; however, most of them are only available by region in some countries. For example, in Romania, there is "Fanta Shokata" based on the traditional Romanian drink "Socată" made from elderflower. In Switzerland and previously the Netherlands the local fruit, blackcurrant is used to produce Fanta as well. Some impossible to tell apart flavors have different names in different markets. The classic orange, for example, was rebranded "Fanta Funky Orange" in 2003 for the Nordic countries and Belgium, while other countries retain the older "Fanta Orange" brand. As of the year 2005, the Fanta brand has been connected with the word Bambaacha (or Bamboocha), which is often seen in the Fanta commercials. TaB diet Cola was originally produced by the Fanta division of Coca-cola and was, at one time, available in a variety of non-cola flavors as well. Later in 2005, Fanta branched out into new Fanta Zero (diet versions) varieties in Great Britain.
