Barge

A barge is a flat-bottomed boat, built mostly for river and canal transport of important goods. Most barges are not self-propelled and need to be moved by tugboats towing or towboats pushing them. Barges on inland waterways (towed by draft animals on an adjacent towpath) contended with the railway in the early industrial revolution but were out competed in the carriage of high value items owing to the higher speed, falling costs, and route elasticity of rail transport.
Barges are still used today for low value bulk items, as the cost of hauling goods by barge is very low. Barges are also used for very weighty or bulky items; a typical barge events 195 feet by 35 feet (59.4 meters by 10.6 meters), and can take up to 1500 tons of cargo.

Empire State Building

The Empire State Building is a 102-story contemporary Art Deco style building in New York City, declared by the American Society of Civil Engineers to be one of the Seven Wonders of the Modern World. Designed by Shreve, Lamb and Harmon, it was finished in 1931. The tower takes its name from the nickname of New York State. Since the September 11th attacks, it is again the tallest building in New York City.

Unlike most of today's high-rise buildings, the Empire State has a classic facade. The building's distinctive art deco spire was originally designed to be a mooring mast and depot for zeppelins. However, after a couple of test attempts with airships, the idea proved to be impractical and dangerous due to the powerful updrafts caused by the size of the building itself, though the T-shaped mooring devices remain in place.

Climate versus weather

In the most succinct words, weather is the combination of events in the atmosphere and climate is the overall accumulated weather in a certain location.The exact boundaries of what is climate and what weather is are not well defined and depend on the application. For example, in some senses an individual El Niño event could be considered climate; in others, as weather.

When the original conception of climate as a long-term average came to be considered, perhaps towards the end of the 19th century, the idea of climate change was not current, and a 30 year average seemed reasonable. Given the current availability of data on long-term trends in the temperature record, it is harder to give a definition of climate to suit all purposes: over a 30 year period, averages may shift; over a shorter period, the statistics are less stable.

Genetic Engineering

Genetic engineering, genetic modification and gene splicing are terms for the process of manipulating genes, usually outside the organism's normal reproductive process. It involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to an herbicide, introducing a novel trait, or producing a new protein or enzyme. Examples can include the production of human insulin through the use of modified bacteria, the production of erythropoietin in Chinese Hamster Ovary cells, and the production of new types of experimental mice such as the OncoMouse for research, through genetic redesign.

Since a protein is specified by a segment of DNA called a gene, future versions of that protein can be modified by changing the gene's underlying DNA. One way to do this is to isolate the piece of DNA containing the gene, precisely cut the gene out, and then reintroduce the gene into a different DNA segment. Daniel Nathans and Hamilton Smith received the 1978 Nobel Prize in physiology or medicine for their isolation of restriction endonucleases, which are able to cut DNA at specific sites. Together with ligase, which can join fragments of DNA together, restriction enzymes formed the initial basis of recombinant DNA technology.

Marriage

A marriage is a relationship between or among individuals, usually recognized by civil authority and/or bound by the religious beliefs of the participants. The fact that marriage often has the dual nature of a binding legal contract plus a moral promise, can make it difficult to characterize.In one form or another, marriage is found in virtually every society. The very oldest records that refer to it speak of it as an established custom. Despite attempts by anthropologists to trace its origin , evidence is lacking.

In Western societies, marriage has traditionally been understood as a monogamous union, while in other parts of the world polygamy has been a common form of marriage. Usually this has taken the form of polygyny but a very few societies have permitted polyandry . Precise definitions vary historically and between and within cultures: modern understanding emphasizes the legitimacy of sexual relations in marriage, yet the universal and unique attribute of marriage is the creation of affinal ties . Traditionally, societies encourage one to marry "out" far enough to strengthen the ties, but "close" enough so that the in-laws are "one of us" or "our kind".

Ice age

An ice age is a period of long-term downturn in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers. Glaciologically, ice age is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice. More colloquially, when speaking of the last few million years, ice age is used to refer to colder periods with extensive ice sheets over the North American and Eurasian continents: in this sense, the last ice age ended about 10,000 years ago. This article will use the term ice age in the former, glaciological, sense; and use the term glacial periods for colder periods during ice ages and interglacial for the warmer periods.

Many glacial periods have occurred during the last few million years, initially at 40,000-year frequency but more recently at 100,000-year frequencies. These are the best studied. There have been four major ice ages in the further past.

Comics

Comics is a form of visual art consisting of images which are commonly combined with text, often in the form of speech balloons or image captions. Originally used to illustrate caricatures and to entertain through the use of amusing and trivial stories, it has by now evolved into a literary medium with many subgenres.

The most common forms of printed comics are comic strips in newspapers and magazines, and longer comic stories in comic books, graphic novels and comic albums. In the first two forms the comics are secondary material usually confined to the entertainment sections, while the latter consist either entirely or primarily of comics.Depending on the definition of the term, the origin of comics can be traced back to 15th century Europe or even as far as to Egyptian hieroglyphs.However, today's form of comics,as well as the term comics itself, originated in the late 19th century.

Kerala

Kerala is a state on the Malabar shore of southwestern India. To its east and northeast, Kerala boundaries Tamil Nadu and Karnataka; to its west and south lie the Indian Ocean islands of Lakshadweep and the Maldives, correspondingly. Kerala envelops Mahé, a coastal exclave of Pondicherry. Kerala is one of four states that create the linguistic-cultural region known as South India.

First settled in the 10th century BCE by speakers of Proto-South Dravidian, Kerala was prejudiced by the Mauryan Empire. Later, the Cheran kingdom and feudal Namboothiri Brahminical city-states became major powers in the region. Early contact with abroad lands culminated in struggles between regal and native powers. Finally, the States Reorganization Act of November 1, 1956 elevated Kerala to statehood. Social reforms enacted in the late 19th century by Cochin and Travancore were prolonged upon by post-Independence governments, making Kerala along with the Third World's longest-lived, healthiest, most gender-equitable, and most educated regions. However, Kerala’s rates of suicide, joblessness, and violent crime rank among India are highest.

Leather from animals

Today, most leather is prepared of cow hides, but many exceptions exist. Lamb and deer skin are used for soft leather in more costly apparels. Kangaroo leather is used to create items which need to be strong but supple, such as motorcycle gloves. Kangaroo leather is preferential by motorcyclists specifically because of its lighter weight and superior scratch conflict as compared to cowhide. Leather made from more striking skins has at different times in history been considered very beautiful. For this reason certain snakes and crocodiles have been sought to near extinction.

In the 1970s, farming of ostriches for their feathers became trendy. As a side product, ostrich leather became accessible. There are different processes to produce special finishes for many applications i.e. upholstery, footwear, automotive, accessories and clothing. Ostrich leather is measured to be of the finest and strongest in the world and at present used by all the big fashion houses like Hermès, Prada, Gucci, and Louis Vuitton. Ostrich leather has an attribute "goose bump" look because of the large follicles from which the feathers grew.

After the monument
Even though the last known construction of Stonehenge was about 1600 BC, and the last known usage of Stonehenge was during the Iron Age where Roman coins, prehistoric pottery, an unusual bone point and a skeleton of a young male were found, we have no idea if Stonehenge was in continuous use or exactly how it was used. The burial of a decapitated Saxon man has also been excavated from Stonehenge, dated to the 7th century. The site was known by scholars during the Middle Ages and since then it has been studied and adopted by numerous different groups. For further details of Stonehenge's historical role, see below.
