United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people.

Air Defense Identification Zone
An air defense identification zone (ADIZ) is a region of airspace in which a country tries to identify, locate, and control aircraft in the interest of national security. It is declared unilaterally and may extend beyond a country's territory to give the country more time to respond to possibly hostile aircraft. The concept of an ADIZ is not defined in any international treaty and is not recognized by any international body. The first ADIZ was established by the United States on December 27, 1950, shortly after President Truman had proclaimed a national emergency during the Korean War. About 20 countries and regions now have such zones, including Canada, India, Japan, Australia, Pakistan, Bangladesh, Finland, Norway, the United Kingdom, the People's Republic of China, South Korea, Taiwan, United States, Iceland, and Iran. As well, Russia and North Korea have unofficial zones.Jane Perlez (27 November 2013)China Explains Handling of B-52 Flight as Tensions Escalate''The New York Tim ...

Nuclear Weapon Yield
The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated. It is usually expressed as a ''TNT equivalent'', the standardized equivalent mass of trinitrotoluene (TNT) which would produce the same energy discharge if detonated, either in kilotonnes (symbol kt, thousands of tonnes of TNT), in megatonnes (Mt, millions of tonnes of TNT). It is also sometimes expressed in terajoules (TJ); an explosive yield of one terajoule is equal to . Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kilotonne of TNT is held simply to be equivalent to 1012 calories. The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatonnes of TNT per tonne of bomb ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of Oxygen saturation, dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to politi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rodong-1
The Hwasong-7} () is a single- stage, mobile liquid propellant medium-range ballistic missile developed by North Korea. Developed in the mid-1980s, it is a scaled-up adaptation of the Soviet R-17 Elbrus missiles, more commonly known by its NATO reporting name "Scud". The inventory is estimated to be around 200–300 missiles. US Air Force National Air and Space Intelligence Center estimates that as of June 2017 fewer than 100 launchers were operationally deployed. It influenced the design of Pakistan's Ghauri-1 missile, as well as the Iranian Shahab-3. Overview It is believed North Korea obtained R-17 designs from Egypt, and possibly modified designs from China, allowing them to reverse-engineer them into a larger and longer-distance weapon. United States reconnaissance satellites first detected this type in May 1990 at the Musudan-ri test launch facility, in northeastern North Korea. In the same year, North Korea began producing Hwasong-7, and eight years later, Hwasong-7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Fuel
Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels that are flammable instead of the fluid. Most liquid fuels in widespread use are derived from fossil fuels; however, there are several types, such as hydrogen fuel (for automotive uses), ethanol, and biodiesel, which are also categorized as a liquid fuel. Many liquid fuels play a primary role in transportation and the economy. Liquid fuels are contrasted with solid fuels and gaseous fuels. General properties Some common properties of liquid fuels are that they are easy to transport, and can be handled with relative ease. Physical properties of liquid fuels vary by temperature, though not as greatly as for gaseous fuels. Some of these properties are: flash point, the lowest temperature at which a flammable concentration of vapor is produced; fire point, the ...
