Oil Paintings

One of the famous painting medium on use is oil paints famous for the look and originality that the oil paint brings in to the paintings. The oil used in painting kept on changing keeping in mind various factors of viscosity, solubility, comfort ability, the color required for the painting and the drying time. Some oils used in historical periods could be flax, walnut, Olive oil or poppyseed oil but the drying time was long for these oil paintings and in the case of olive oil it was excessively long which brought in usage of drying oil as a varnish on oil paintings.

Types of Water Treatment:

Water Conditioners:
This is one of the most efficient water treatment method and the water which comes out from them has low sodium diets .it does not contain Lime scales Water which intakes appliances lasts for a longer period. It increases the efficiency of heat. It also the effectiveness of soap, it retains calcium and it is very good for health, it has low running cost. The disadvantage is that it wont treats any specific hard water problems, which is clearly described in http://www.water-filters-purifiers-softeners.com/.

Water softeners:
The water softeners takes off lime scale, it brings up heating efficiency and it increases the life span of clothes.

Activated carbon water filters:

They are good in removing chlorine from the water and they are also efficient in removing organic efficiency. This filtration does not deal with microbes, sodium, nitrates, fluorides and hardness.Ultraviolet water filters:
These filters have maximum fabrication capacity and they kill 99% of the germs they are passing through. But these filters do not remove dead cells and do not kill other contaminants.

Water Distillers:
Takes away the natural water cycle processes. Distilled Water is very pure and it is free from all the impurities. It has low Filtration Capacity and high running cost.

WAN

A wide area network or WAN is a computer network covering a wide geographical area, involving a vast array of computers. This is different from personal area networks (PANs), metropolitan area networks (MANs) or local area networks (LANs) that are usually limited to a room, building or campus. The best example of a WAN is the Internet.
WANs are used to connect local area networks (LANs) together, so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are most often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs. X.25 was an important early WAN protocol, and is often considered to be the "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.
Academic research into wide area networks can be broken down into three areas: Mathematical models, network emulation and network simulation.

Western Meadowlark

The Western Meadowlark, Sturnella neglecta, is a medium-sized blackbird, very similar in appearance to the Eastern Meadowlark.
Adults have yellow underparts with a black "V" on the breast and white flanks with black streaks. The upperparts are mainly brown with black streaks. They have a long pointed bill; the head is striped with light brown and black.
Their breeding habitat is grasslands and prairie, also pastures and abandoned fields, across western and central North America to northern Mexico. Where their range overlaps with the eastern species, these birds prefer thinner, drier vegetation; the two birds generally do not interbreed but do defend territory against each other. The nest is on the ground, covered with a roof woven from grasses. There may be more than one nesting female in a male's territory.
These birds are permanent residents throughout much of their range. Northern birds migrate to the southern parts of the range; some birds also move east in the southern United States.
These birds forage on the ground or in low vegetation, sometimes probing with its bill. They mainly eat insects as well as seeds and berries. In winter, they often feed in flocks.
This bird has a flute-like warbled song, unlike the simple whistled call of the Eastern Meadowlark. They were considered to be the same species for some time; the western species, having been overlooked for some time, was given the species name neglecta.

1943: New Guinea, submarine warfare

Exhausted Australian and US forces then strove to retake the occupied parts of New Guinea and the Dutch East Indies, experiencing some of the toughest resistance of the Pacific Theatre. The rest of the Solomon Islands were retaken in 1943, New Britain and New Ireland in 1944. The Philippines were attacked in late 1944 following the Battle of Leyte Gulf.
US and Allied submarines and aircraft also attacked Japanese merchant shipping, depriving Japanese industry of the raw materials she had gone to war to obtain. The effectiveness of this stranglehold increased as the U.S. captured islands closer to the Japanese mainland.
The Nationalist Kuomintang Army under Chiang Kai-shek and the Communist Chinese Army under Mao Zedong both opposed the Japanese occupation of China, but never truly allied against the Japanese. Conflict between Nationalist and Communist forces continued after and, to an extent, even during the war.
The Japanese captured most of Burma severing the Burma Road by which the Western Allies had been supplying the Chinese Nationalists. This forced the Allies to create a large sustained airlift of the war known as the Hump. US lead and trained Chinese divisions, a few thousand US ground forces and a British Division, cleared the Japanese forces from northern Burma so that the Ledo Road could be built to replace the Burma Road. Further south the main Japanese army in the theater were fought to a standstill on the Burma India frontier by the British Fourteenth Army (the "forgotten" army) which then counter-attacked and having recaptured all of Burma was planning attacks towards Malaya when the war ended.
