Government Agency
A government or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government that is responsible for the oversight and administration of specific functions, such as an administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role—this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, independence, and accountability of government agencies also vary widely. History Early e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Geographical Organization Of Iran
The National Geographical Organization of Iran or National Geographical Organization of the Armed Forces of Iran ( fa, سازمان جغرافیایی ایران, or fa, سازمان جغرافیایی نیروهای مسلح) is an Iranian government agency affiliated to the Ministry of Defence and Armed Forces Logistics of Iran, which has been established to prepare quick and accurate access spatial information of the country and other areas required by the Armed Forces of Iran.

Of course, origin of this mapping organization and formation of surveying and cartography branches, was laid in 1921, and in the course of its evolution, it performed responsibilities in accordance with the needs, missions and organizational duties. Finally, it is identified as the ''National Geographical Organization of Iran'' or ''National Geographical Orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science And Technology In Iran
Iran has made considerable advances in science and technology through education and training, despite international sanctions in almost all aspects of research during the past 30 years. Iran's university population swelled from 100,000 in 1979 to 2 million in 2006. In recent years, the growth in Iran's scientific output is reported to be the fastest in the world. Science in ancient and Medieval Iran (Persia) Beginning in ancient times Persia has been a center of scientific achievement and was often the conduit of knowledge from China and India in the East to Greece and Rome in the West. Persian-speaking scholars have been active in furthering knowledge in fields of science and technology, such as astronomy, chemistry, anatomy, biology, botany, cosmology, mathematics, engineering, and architecture. Science in Persia evolved in two main phases separated by the arrival and widespread adoption of Islam in the region. References to scientific subjects such as natural science an ...

Radiosonde
A radiosonde is a battery-powered telemetry instrument carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver. Modern radiosondes measure or calculate the following variables: altitude, pressure, temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude and geographical position (latitude/longitude). Radiosondes measuring ozone concentration are known as ozonesondes. Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz. A radiosonde whose position is tracked as it ascends to give wind speed and direction information is called a rawinsonde ("radar wind -sonde"). Most radiosondes have radar reflectors and are technically rawinsondes. A radiosonde that is dropped from an airplane and falls, rather than being carried by a balloon is called a dropsonde. Radiosondes are an essential source of meteorological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karun
The Karun ( fa, کارون, ) is the Iranian river with the highest water flow, and its only navigable river. It is long. It rises in the Zard Kuh mountains of the Bakhtiari district in the Zagros Range, receiving many tributaries, such as the Dez and the Kuhrang, before passing through the capital of the Khuzestan Province of Iran, the city of Ahvaz before emptying to its mouth into Arvand Rud (Shatt al-Arab). The Karun continues toward the Persian Gulf, forking into two primary branches on its delta – the Bahmanshir and the Haffar – that join the Arvand Rud, emptying into the Persian Gulf. The important Island of Abadan is located between these two branches of the Karun. The port city of Khorramshahr is divided from the Island of Abadan by the Haffar branch. Juris Zarins and other scholars have identified the Karun as one of the four rivers of Eden, the others being the Tigris, the Euphrates, and either the Wadi Al-Batin or the Karkheh.

Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of na ...

Modern Ray is an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786, because of its proximity to Iran's territories in the Caucasus, then separated from Iran in the Russo-Iranian Wars, to avoid the vying factions of the previously ruling Iranian dynasties. The capital has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
