Hydrogen
The sun is basically a giant ball of hydrogen and helium gases. In the sun's core, hydrogen atoms combine to form helium atoms. This process—called fusion—gives off radiant energy.
This radiant energy sustains life on earth. It gives us light and makes plants grow. It makes the wind blow and rain fall. It is stored as chemical energy in fossil fuels. Most of the energy we use today came from the sun's radiant energy.
Hydrogen gas is lighter than air and, as a result, it rises in the atmosphere. This is why hydrogen as a gas (H2) is not found by itself on earth. It is found only in compound form with other elements. Hydrogen combined with oxygen, is water (H2O). Hydrogen combined with carbon, forms different compounds such as methane (CH4), coal, and petroleum. Hydrogen is also found in all growing things—biomass. It is also an abundant element in the earth's crust.
Hydrogen has the highest energy content of any common fuel by weight(about three times more than gasoline), but the lowest energy content by volume (about four times less than gasoline). It is the lightest element, and it is a gas at normal temperature and pressure.

Cricket in India
In cities like Calcutta, with everybody glued to their TV sets, life grinds to a stop the progress of the days the Indian team is playing. One-day gear and test matches stimulate equal eagerness; for together, if the match is being played on Indian earth, which by the way supports spin slightly than pace, you’ll get aptitude crowds and a emotional atmosphere seldom matched anywhere outside the subcontinent. Allegations of murky match fixing and a fixed string of matches where the team managed to “grab defeat from the jaws of victory” notwithstanding, the attractiveness of the game continues to rise. Such is the strength of participation with the game that it even affects India’s international relationships. In the result of the 1999 Kargil war, India unilaterally overhanging cricketing relations with Pakistan. The discuss on whether politics and sports should mix enlivens many a discussion, and is yet unresolved.

Christmas Day
To people all over the earth, Christmas is a flavor of giving and receiving presents. In some European countries, priest Christmas, or Saint Nicholas, comes into houses in the night and leaves gifts for the children. Saint Nicholas is represented as a kindheartedly man with a red cloak and long white beard. Another nature, the Norse God Odin, ride on a mysterious flying horse across the sky in the winter to prize people with gifts. These different myths passed across the ages to make the present day Santa Claus.
On December 24, Christmas Eve, Santa hitches his eight reindeer to a toboggan and loads it with presents. The reindeer drag him and his sleigh through the sky to deliver presents to children all around the earth, that is, if they had been good all year. Several American towns maintain the strength of Santa Claus.
Santa Claus exists only in our imagination. But he, Saint Nicholas, and father Christmas are feelings of giving. Christmas has been associated with gift giving since the Wise Men brought gifts to welcome the newborn Jesus Christ.In eagerness of Santa's visit, American children pay attention to their parents read "The Night previous to Christmas" before they go to bed on Christmas Eve

The Banyan Tree
Its size and leafy shelter are valued in India as a place of relax and mirror image, not to mention defense from the hot sun! It is still the focus and gathering place for local councils and meetings. India has a long history of worship this tree; it figures importantly in many of the oldest stories of the nation.

A Snapshot of Macro-Economics
Studying the world economy is classified as Macroeconomics; its center on a much broader level. All students must understand the concept of insufficiency. Scarcity is a condition that occurs because society has unlimited wants and needs however the amount of property is limited. Unlimited wants and needs are what encourage us to create goods and services. We are never satisfied therefore we always have a want or need. On the other hand our income is limited.

Life was simply the stack of decayed flesh that enclosed her. From his immortal lips hung the bodies of all those who died struggle for him and all those who had tampered with self luxury. For that, she dammed him for all eternity; in every form he understood she dammed him. He had been her guiding angle and now it became evident to her. No prayer would pass her conditions lips, for this had been his movement she had fought and they had lost other than just a clash.

Cucumber
Cucumbers can be pickled for taste and longer shelf life. As compare to eating cucumbers, pickling cucumbers tend to be shorter, thicker, less regularly-shaped, and have rough skin with tiny white- or black-dotted spines. They are not at all waxed. Color can be different from creamy yellow to pale or dark green. Pickling cucumbers are sometimes sold fresh as "Kirby" or "Liberty" cucumbers. The pickling practice removes or degrades a large amount of the nutrient content, particularly that of vitamin C. Pickled cucumbers are waterlogged in vinegar or brine or a combination, often along with a mixture of spices.
• English cucumbers can cultivate as long as 2 feet. They are nearly seedless and are sometimes marketed as "Burp less."
• Japanese cucumbers (kyūri) are mild, deep green, slenderand have a bumpy, ridged skin. They can be used for slicing, pickling, salads, etc., and are available year-round.
• Mediterranean cucumbers are smooth-skinned, small and mild. Like the English and Mediterranean cucumbers are nearly seedless.

Java shaped mostly as the result of volcanic events, Java is the 13th leading island in the world and the fifth major island of Indonesia. A sequence of volcanic mountains forms an east-west spine along the island. It has three main languages, and most populace are bilingual, with Indonesian as their second language. While the popular of Javanese are Muslim (or at least supposedly Muslim), Java has a different mixture of religious beliefs and cultures.

Java Coffee
A rust disease in the late 1880s killed off much of the plantation stocks in Sukabumi, before distribution to Central Java and parts of East Java. The Dutch respond by replacing the Arabica firstly with Liberica (a tough, but somewhat unpleasant coffee) and later with Robusta. Today Java's old royally era plantations provide just a portion of the coffee grown on the island. Logo of Java programming language is a coffee cup.

Coconut cream
Creamed coconut is disproportionate as coconut cream. Creamed coconut is a very determined coconut takes out without the water. Like coconut oil, it is tough at a low room temperature. It is basically coconut cream ponder, and can be made into coconut cream by mixing it with water, or into coconut milk by adding it with a larger amount of water. It is naturally sold as a 200ml block in a plastic bag inside a small box.
In the UK it is easily available (from £0.30 to £1.00 per 200ml block) in Asian convenience stores and in the Asian sections of large supermarkets.
Coconut cream is soaring in healthy medium chain fatty acids and is very wealthy in flavor. Coconut cream is used in Bangladeshi, and its nonalcoholic variant Virgin Piña Coladas, and Piña Coladas cooks often add coconut cream to rice to give it some flavor.

Lopping
Lopping in many cases is careful an inappropriate pruning method for amenity trees. The lopped stubs may regrow adventitious epicormic shoots which are bonded only to the bark. These epicormic shoots can grow dynamically and, unless regularly pruned off, may outgrow the original height and spread of the tree. Further, the ends of the lopped stubs are exposed to pathogens which may enter and infect the tree.
In orchards, fruit trees are often lopped to encourage regrowth and to keep a smaller tree for ease of picking fruit. The pruning regime in orchards is more intended and the productivity of each tree is an important factor. In an orchard, though, the natural longevity of a tree is often compromised in favor of its output in fruiting. Orchard trees are also carefully monitored and treated with fungicides and insecticides to minimise losses.

Krill fishery
Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superba). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrases, nucleases and phospholipases, which are intense in the digestive gland in the cephalothorax of the krill.
Most krill is used as aquaculture feed and fish bait; other uses comprise livestock or pet foods. Only a small percentage is prepared for human consumption. Their enzymes are interesting for medical applications, an expanding sector since the early 1990s.

Mango
Mangos retain a special significance in the culture of South Asia where they have been cultured for millennia. It has been the national symbol of the Philippines. Reference to mangoes as the "food of the gods" can be found in the Hindu Vedas and the leaves are ritually used for floral decorations at Hindu marriages and religious ceremonies.

Swan
Swans typically mate for life, though "divorce" does sometimes occur, mainly following nesting failure. The number of eggs in each clutch is between 3–8.
The word is derived from Old English swan, akin to German Schwan, in turn derived from Indo-European root *swen (to sound, to sing), whence Latin derives sonus (sound). Young swans are known as cygnets, from the Latin word for swan, cygnus. An adult male is a cob, from Middle English cobbe; an adult female is a pen .

Grafting
In most cases, one plant is chosen for its roots, and this is called the stock or rootstock. The other plant is chosen for its stems, leaves, flowers, or fruits and is called the scion.
In stem grafting, a common grafting method, a shoot of a chosen, desired plant cultivar is grafted onto the stock of another type. In another common form called budding, a dormant side bud is grafted on the stem of another stock plant, and when it has fused successfully, it is encouraged to grow by cutting out the stem above the new bud.
For successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be located in contact with each other. Both tissues must be kept alive till the graft has taken, typically a period of a few weeks. Successful grafting only requires that a vascular connection takes place between the two tissues. A physical weak point often still occurs at the graft, because the structural tissue of the two distinct plants, such as wood may not fuse.

Cooking
The diversity of cooking worldwide is a reflection of the myriad nutritional, aesthetic, agricultural, economic, cultural and religious considerations that impact upon it.
Cooking require applying heat to a food which usually, though not always, chemically transforms it, thus changing its flavor, texture, appearance, and nutritional properties.Cooking proper, as different to roasting, requires the boiling of water in a container, and was practiced at least since the 10th millennium BC with the introduction of pottery. There is archaeological evidence of roasted foodstuffs at Homo erectus campsites dating from 420,000 years ago.

Peafowl
Overview
The characteristic Asiatic peafowl belonging to the genus Pavo comprise the familiar Indian Peafowl, Pavo cristatus and the poorly known Dragon birds or Green Peafowl Pavo muticus. Some biologists believe that there are at least five characteristic and critically endangered species of Green Peafowl while others classify them into a single species with three species.
The Arakan Dragonbird Pavo spicifer was once inhabitant to Northern Western Myanmar, Southern Tibet and Assam. The Indo-Chinese or Siamese Dragon bird Pavo imperator was once native to South East Myanmar and Thailand. The Annametic Dragonbird Pavo annamensis occupied the broadleaf evergreen forests of Cambodia, Vietnam, Laos and Southern Yunnan China.
The Javanese Green Peafowl, Pavo javanensis is occupant only to the island of Java. The died out Malay or Pahang Peafowl Pavo muticus muticus was fantasy by early naturalists to least the Pliocene rules out an foreword by humans. Northern Yunnan is the home of one of the most fascinating forms of Green Peafowl. The Yunnan Dragonbird, Pavo yunnanensis is most characteristic.

Ginger
Originating in southern China, cultivation of ginger spread to India, Southeast Asia, West Africa, and the Caribbean.Ginger contains up to 3% of an essential oil that causes the fragrance of the spice. The main constituents are sesquiterpenoids with (-)-zingiberene as the main component. Lesser amounts of other sesquiterpenoids and a small monoterpenoid fraction have also been identified.
The pungent taste of ginger is due to nonvolatile phenylpropanoids (particularly gingerol and zingerone) and diarylheptanoids (gingeroles and shoagoles); the latter are more pungent and form from the former when ginger is dried. With a specific procedure is used for cooking, where ginger root acquires a soda form and transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.

The term is occasionally used in the common parlance of several countries to refer to any German Shepherd Dog because of the long history of the use of the German Shepherd by the police and military; in some nations German Shepherds are the only dogs used by those forces. In the post-industrial era German Shepherds have often been depicted as police dogs in television, movies and police dog memorials. This breed is often still used, as are a few other breeds.

Arrestors
When lightning exceeds the arrestor's breakdown voltage, the currents arcs to the ground and prevents arcing around inside sensitive electronic equipment joined further down line. The glimmer gap may be filled with a noble gas, or with air. Other types may work by overcrowding normal irregular current, but allowing the direct current from a lightning discharge.
Lightning arrestors are normally installed on electric power broadcast lines, and on radio tower feed lines between the radio antenna and spreader. Smaller ones can also be installed on the mains electricity service coming into a building, just before the circuit breaker panel. Telephone wires also have fusible links sometimes where they enter a building, joined by carbon which will vaporize with very high current.

Speed limit
Design speed
Speed limits are only peripherally interrelated to the design speed of the road.
In the United States, the design speed is "a selected speed used to establish the various geometric design features of the roadway" according to the 2001 AASHTO Green Book, the highway design manual. It has been changed from previous versions which considered it the "highest safe speed that can be maintained over a specific section of highway when conditions are so positive that the design facial appearance of the highway governs."
The design speed has largely been discredited as a sole basis for establishing a speed limit. Current U.S. standards for design speed derive from outdated, less-capable automotive technology. Also, the design speed of a given roadway is the theoretical maximum safe speed of the roadway's worst feature .The design speed usually underestimates the highest safe speed for a roadway and is therefore considered only a very conservative "first guess" at a limit.
85th percentile rule
An automobile dashboard viewing the speedometer with primary markings in miles per hour.Since the 1950s, United States traffic engineers have been taught the 85th Percentile Rule. The idea is that the speed limit should be set to the speed below which 85% of vehicles are traveling. The 85th percentile closely corresponds to one normal deviation above the mean of a normal distribution.
Every state in the United States statutorily or administratively picks a particular speed for a speed limit cap, meaning that no speed limit in that state may be set higher than the cap. A practical effect of this cap is that nearly every rural roadway in the U.S. has a speed limit that is well below the 85th percentile speed.

The world's first self-striking clock was said to be invented by Chang Yeong-Sil, a chief enginner of Korea, in Korea during the Joseon Dynasty. It was called Chagyongru, which means "self-striking clock" in Korean
The development of electronics in the twentieth century led to clocks with no clockwork parts at all. Time in these cases is measured in several ways, such as by the behaviour of quartz crystals, or the decay of radioactive elements. Even mechanical clocks contain since come to be largely powered by batteries, removing the need for winding.

Videophone
AT&T conducted experiments and demonstrations of a "Picturephone" product and service in the early 1960s. Among the first manufacturers of commercially viable videophones was Toshiba.
Videotelephony is frequently used in large corporate setups, and are supported by systems such as Cisco CallManager. Other companies such as Tandberg, Radvision, and Polycom also offer similar solutions. Videoconferencing has usually been limited to the h.323 protocol (notably Cisco's SCCP implementation is an exception), however newly a shift towards SIP implementations is seen. In accordance with the adoption of SIP telephony for home users, videotelephony is also slowly becoming available to home users.
Another protocol using videophones is H.324; this allows videophones to work in regular phone lines, since the bandwidth is limited by the phone line. The quality is about fifteen Frames per second. This type of videophone is generally used because of the affordable price.
Today the principles, if not the precise mechanisms of a videophone are employed by thousands of users world-wide in the form of webcam conferences using cheaply available webcams and microphones employed using software over the internet.

Mainframe computer
The term originated through the early 1970s with the introduction of smaller, less complex computers such as the DEC PDP-8 and PDP-11 series, which became known as minicomputers or just minis. The industry/users then coined the term "mainframe" to describe larger, earlier types (previously known simply as "computers").
Modern mainframe computers contain abilities not so much defined by their performance capabilities as by their high-quality internal engineering and resulting proven reliability, expensive but high-quality technical support, top-notch security, and strict backward compatibility for older software. These machines can and do run successfully for years with no interruption, with repairs taking place whilst they continue to run. Mainframe vendors offer such services as off-site redundancy — if a machine does break down, the vendor offers the option to run customers' applications on their own machines (often without users even noticing the change) whilst repairs go on.

Polymer
The monomers can be identical, or they can have one or more substituted chemical groups. These differences between monomers can have an effect on properties such as solubility, flexibility, or strength. In proteins, these differences can give the polymer the ability to preferentially adopt one conformation over another, as opposed to adopting a random coil (see self-assembly). Although most polymers are organic (based on carbon chains), there are also inorganic polymers, mainly based on a silicon backbone.
The term polymer covers a large, diverse group of molecules, including substances from proteins to high-strength kevlar fibres. A key feature that distinguishes polymers from other large molecules is the repetition of units of atoms (monomers) in their chains. This occurs during polymerization, in which many monomer molecules link to each other.

Geography of Aruba
Aruba is a generally flat, riverless island famous for its white sand beaches. Most of these are situated on the western and southern coasts of the island, which are comparatively sheltered from fierce ocean currents. The northern and eastern coasts, absence of this protection, are significantly more battered by the sea and have been left largely untouched by humans. The center of the island features some rolling hills, the better two of which are called Hooiberg at 165 m (541 ft) and Mount Jamanota, which is the uppermost on the island, at 188 m (617 ft) above sea level.
As a separate part of the Kingdom of the Netherlands, the island has no administrative subdivisions. On the east are Curaçao and Bonaire, which form the southwest part of the Netherlands Antilles; the three islands are well-known collectively as the ABC islands.
The local climate is a pleasant tropical marine clime. Little seasonal temperature difference exists, which helps Aruba to attract tourists all year round. Temperatures are almost constant at about 28 degrees Celsius (85 degrees Fahrenheit), moderated by constant trade winds from the Atlantic Ocean. Yearly precipitation barely reaches 500 mm (20 inches), the majority of it falling in late autumn.

Amazon Rainforest
The rainforest is supported by the extremely wet climate of the Amazon basin. The Amazon, and its hundreds of tributaries, flow gradually across the landscape, with an enormously shallow gradient sending them towards the sea: Manaus, 1,600 km (1,000 mi) from the Atlantic, is only 44 m (144 ft) above sea level.
The biodiversity within the rainforest is extraordinary: the region is home to at least 2.5 million insect species, tens of thousands of plants, and some 2,000 birds and mammals. One fifth of all the world's species of birds can be found in the Amazon rainforest.
The diversity of plant species in the Amazon basin is the highest on Earth. Some experts estimate that one square kilometre may contain over 75,000 types of trees and 150,000 species of higher plants. One square kilometre of Amazon rainforest can contain about 90,000 tons of living plants.

Morello Cherry
The tree is smaller than the Wild Cherry, increasing up to 4-10 m tall, and has twiggy branches, whilst the crimson to black fruit is borne on shorter stalks.
Sour Cherries require comparable cultivation conditions to pears, that is, they prefer a rich, well-drained moist soil, although they demand more nitrogen and water than sweet cherries. Trees will do badly if waterlogged, but have larger tolerance of poor drainage than sweet varieties. As with sweet cherries, Morellos are usually cultivated by budding onto strong growing rootstocks, which produce trees too large for most gardens, although newer dwarfing rootstocks such as Colt and Gisella are now available. During spring, flowers should be sheltered, and trees weeded, mulched and sprayed with seaweed solution. This is also the time when any required pruning should be carried out (note that cherries should not be pruned during the dormant winter months). Morello cherry trees fruit on younger wood than sweet varieties, and thus can be pruned harder. They are usually grown as standards, but can be fan trained, cropping well even on cold walls, or grown as low bushes.

Industry
Industry in the second sense became a key sector of manufacture 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 growth 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 quickly 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 financial output is derived from manufacturing industries—more than agriculture's share.

Origins of river water
Excessive abstraction of water for use in industry, irrigation etc can also cause a river to dry before getting a lake or the sea.The mouth, or lower end, of a river is recognized by hydrologists as its base level.The area drained by a river and its tributaries is called catchment, catchment basin, drainage basin or watershed. The term "watershed" is also used to mean a boundary between catchments, which is also called a water divide.

The computer
Charles Babbage was the first to conceptualize and design a completely programmable computer as early as 1820, In 1801, Joseph Marie Jacquard made an improvement to the presented loom designs that used a series of punched paper cards as a program to weave involved patterns. The resulting Jacquard loom is not considered a true computer but it was an essential step in the growth of modern digital computers.
but due to a combination of the restrictions of the technology of the time, limited finance, and an incapability to resist tinkering with his design, the device was never really constructed in his lifetime. By the end of the 19th century a number of technologies that would later prove helpful in computing had appeared, out such as the punch card and the vacuum tube, and large-scale automated data giving using punch cards was performed by tabulating equipment designed by Hermann Hollerith.During the first half of the 20th century, many technical computing wants were met by increasingly difficult special-purpose analog computers, which used a direct mechanical or electrical model of the problem as a base for subtraction (they became ever more rare after the development of the programmable digital computer). Sequence of gradually more powerful and stretchy computing devices were construct in the 1930s and 1940s.

The Real Miracle
The water of Mahim Creek, sweetened or otherwise, is dirty and would scandalize not only the likes of Sunita Narain of the Centre for Science and Environment. Maharashtra Chief Minister Vilasrao Deshmukh and officials of the Municipal Corporation of Greater Mumbai have already request to people not to drink the water. Industrial waste is not the finest ingredient for a miracle. But telling this to goggle-eyed people facing even more goggle-eyed TV cameras is as worthwhile as persuasive people that a Ganesh idol sipping milk is caused by suction and not godly lactose tolerance.
Fortunately, rumors of the sweetened water turning back to its original brackish form might stop a future surge. Now we only wait for the real miracle of no one complaining of sickness.

Journalism Basics
That's not all, though. In addition to dedicated training in writing, editing, and reporting, Journalism wants a working knowledge of history, culture, and current events. You'll more than likely be required to take up a broad range of courses that runs the range from statistics to the hard sciences to economics to history. There would also be a lot of haughty talk about professional ethics and civic responsibility too - and you'll be tested on it. To top it all off, you'll perhaps work on the university newspaper or radio station, or possibly complete an internship with a magazine or a mass media conglomerate.
