Surindar Kumar Trehan
Surindar Kumar Trehan (S.K. Trehan) was an Indian mathematician who specialised in non-linear stability in magnetohydrodynamics. He was awarded in 1976 the Shanti Swarup Bhatnagar Prize for Science and Technology The Shanti Swarup Bhatnagar Prize for Science and Technology (SSB) is a science award in India given annually by the Council of Scientific and Industrial Research (CSIR) for notable and outstanding research, applied or fundamental, in biology, ..., the highest science award in India, in the mathematical sciences category. Prof. Trehan has done significant work on stability of force-free magnetic fields, stability of jets and cylinders and stability of inhomogeneous plasmas. His work on the mathematical treatment of gaseous polytropes in the presence of a magnetic field is a breakthrough in this area. He has also done important work on hydromagnetic waves and rotating gaseous masses. Short Biography Please note that the authorization of this article belongs t ...

West Punjab
West Punjab ( pnb, ; ur, ) was a province in the Dominion of Pakistan from 1947 to 1955. The province covered an area of 159,344 km2 (61523 sq mi), including much of the current Punjab province and the Islamabad Capital Territory, but excluding the former Princely state of Bahawalpur. The capital was the city of Lahore and the province was composed of four divisions (Lahore, Sargodha, Multan and Rawalpindi). The province was bordered by the princely state of Bahawalpur to the south, the province of Baluchistan to the south-west and Sind to the south, North-West Frontier Province to the northwest, and Azad Kashmir to the north. It shared International border with Indian state of East Punjab and Indian-administered Jammu & Kashmir to the east. It acceeded to West Pakistan upon creation of One Unit Scheme. History The creation of Pakistan in 1947 led to the division of the Punjab Province of British India into two new provinces. The largely Sikh and Hindu East Punjab became p ...

Magnetic Fields
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, c ...

Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–''what'' they are, rather than ''where'' they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic a ...

Intelligence And National Security Alliance
The Intelligence and National Security Alliance (INSA) is a non-profit, nonpartisan 501(c)(6) professional organization based in Arlington Virginia for public and private sector members of the United States Intelligence Community. History INSA was founded in 1979 as the Security Affairs Support Association (SASA) to bring together professionals in the intelligence field, primarily focused on the National Security Agency, and to assist members in staying current on intelligence and national security community issues. SASA's headquarters were in Annapolis Junction, Maryland. Maj Gen John E. Morrison, Jr., a 2001 NSA Hall of Honor Inductee, served as president of SASA from 1979 to 1999. SASA's Board of Directors voted in November 2005 to rename the organization the Intelligence and National Security Alliance (INSA) in order to broaden its reach across the intelligence and national security communities and better serve the community in the period following the establishment of ...

Governing Council Of Indian Statistical Institute And Indian Association For The Cultivation Of Science
Governance is the process of interactions through the laws, norms, power or language of an organized society over a social system (family, tribe, formal or informal organization, a territory or across territories). It is done by the government of a state, by a market, or by a network. It is the decision-making among the actors involved in a collective problem that leads to the creation, reinforcement, or reproduction of social norms and institutions". In lay terms, it could be described as the political processes that exist in and between formal institutions. A variety of entities (known generically as governing bodies) can govern. The most formal is a government, a body whose sole responsibility and authority is to make binding decisions in a given geopolitical system (such as a state) by establishing laws. Other types of governing include an organization (such as a corporation recognized as a legal entity by a government), a socio-political group (chiefdom, tribe, gang ...

Boundary (thermodynamic)
A thermodynamic system is a body of matter and/or radiation, confined in space by walls, with defined permeabilities, which separate it from its surroundings. The surroundings may include other thermodynamic systems, or physical systems that are not thermodynamic systems. A wall of a thermodynamic system may be purely notional, when it is described as being 'permeable' to all matter, all radiation, and all forces. A state of a thermodynamic system can be fully described in several different ways, by several different sets of thermodynamic state variables. A widely used distinction is between ''isolated'', ''closed'', and ''open'' thermodynamic systems. An isolated thermodynamic system has walls that are non-conductive of heat and perfectly reflective of all radiation, that are rigid and immovable, and that are impermeable to all forms of matter and all forces. (Some writers use the word 'closed' when here the word 'isolated' is being used.) A closed thermodynamic system is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
