Ships Built In San Francisco
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, a ...

Powell River, British Columbia
Powell River is a city on the northern Sunshine Coast of southwestern British Columbia, Canada. Most of its population lives near the eastern shores of Malaspina Strait, which is part of the larger Georgia Strait between Vancouver Island and the Mainland. With two intervening long, steep-sided fjords inhibiting the construction of a contiguous road connection with Vancouver to the south, geographical surroundings explain Powell River's remoteness as a community, despite relative proximity to Vancouver and other populous areas of the BC Coast. The city is the location of the head office of the qathet Regional District. History The Powell River was named for Israel Wood Powell, Powell was B.C.'s first superintendent for Indian Affairs and a chief architect of colonial policies including residential schools and the banning of the Potlatch. He was traveling up the coast of BC in the 1880s and the river and lake were named after him. Powell River is named after Israel Wood Powel ...

Log Pond
A log pond is a small natural lake or reservoir used for storage of wooden logs in readiness for milling at a sawmill. Although some mill ponds served this purpose for water-powered sawmills, steam-powered sawmills used log ponds for transportation of logs near the mill; and did not require the elevation drop of watermill reservoirs. Background The earliest mechanized sawmills of the industrial revolution were built on navigable rivers, lakes, or estuaries where logs could be floated to the sawmill and lumber could be carried to markets aboard ships or barges. Early steam sawmills included a hoist to lift logs out of the water onto a carriage which moved the log past a stationary powered saw. Men could relatively easily push floating logs into position to be lifted by the hoist. Forests distant from navigable water became accessible with the development of railroads. Sawmills adjacent to navigable waters were termed cargo mills, in contrast to interior rail mills relying upon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catalyst Paper
Catalyst Paper Corporation is a pulp and paper company based in Richmond, British Columbia. It operates five pulp mills and paper mills, producing a combined 1.8 million tonnes of paper and 491,000 tonnes of market pulp annually. The mills mostly produce magazine paper and newsprint. The company was established as NorskeCanada in 2000, when Norske Skog bought the majority of Fletcher Challenge Canada with Elk Falls Mill and Crofton Mill. The following year Pacifica Papers, operating Port Alberni Mill and Powell River Mill, was merged into the group. A recycling plant in Coquitlam was bought in 2003. The group took the Catalyst name in 2005 and the following year Norske Skog sold their shares. Snowflake Mill was bought in 2008. In the following two years the Elk Falls, Coquitlam and one machine at Crofton were shut down. Snowflake followed suit in 2012. The reason was falling demand for newsprint and increased cost of recycled paper. Catalyst reentered US production in 2015 ...

Powell River Company
MacMillan Bloedel Limited, sometimes referred to as "MacBlo", was a Canadian forestry company headquartered in Vancouver, British Columbia. It was formed through the merger of three smaller forestry companies in 1951 and 1959. Those were the Powell River Company, the Bloedel Stewart Welch Company, and the H.R. MacMillan Company. It was bought by Weyerhaeuser of Federal Way, Washington in 1999. Powell River Company In 1908 two American entrepreneurs, Dr. Dwight Brooks and Michael Scanlon, created a newsprint mill at Powell River, northwest of Vancouver. The Powell River Company turned out the first roll of newsprint manufactured in British Columbia in 1912. It soon became one of the world's largest newsprint plants and today is credited with introducing the first self-dumping log barge to British Columbia. Bloedel, Stewart and Welch In 1911 Julius Bloedel, a Seattle lawyer, along with his two partners, John Stewart and Patrick Welch, began acquiring large blocks of Vancouve ...

Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants, produces ionizing radiation (namely alpha, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge ...

Kwajalein
Kwajalein Atoll (; Marshallese language, Marshallese: ) is part of the Marshall Islands, Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents (about 1,000 mostly U.S. civilian personnel) often use the shortened name, Kwaj . The total land area of the atoll amounts to just over . It lies in the Ralik Chain, southwest of Honolulu, Honolulu, Hawaii. The US Navy has hosted a naval base on Kwajalein Island since World War II. It was the final resting place of the German cruiser ''German cruiser Prinz Eugen, Prinz Eugen'' after it survived the Operation Crossroads nuclear test in 1946. In the late 1950s, the US Army took over the base as part of their Nike Zeus anti-ballistic missile efforts, and since then the atoll has been widely used for missile tests of all sorts. Today it is part of the Ronald Reagan Ballistic Missile Defense Test Site, with various radars, tracking came ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deplo ...

Operation Crossroads
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity in July 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945. The purpose of the tests was to investigate the effect of nuclear weapons on warships. The Crossroads tests were the first of many nuclear tests held in the Marshall Islands, and the first to be publicly announced beforehand and observed by an invited audience, including a large press corps. They were conducted by Joint Army/Navy Task Force One, headed by Vice Admiral William H. P. Blandy rather than by the Manhattan Project, which had developed nuclear weapons during World War II. A fleet of 95 target ships was assembled in Bikini Lagoon and hit with two detonations of Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki in 1945, each with a yield of .
