Every kind of sport and game is extremely vital for us as they keep us vigorous, healthy and fit. Also they present us a change from the normal daily life and are valuable form of enjoyment and physical activity. Besides, the physical activity helps the new generation in their character building, and also provides endurance and fitness. Sports and games are the usual means of mental and physica...

The gap between the world's rich and poor countries largely comes down to the financial and physical assets that create wealth. Developed economies possess more of this capital than developing ones, and what they have usually incorporates more advanced technologies. The implication is clear: A key aspect of economic advancement lies in poorer nations' capacity to acquire more capital and scale ...

By a systematic method we construct general classes of exact and selfconsistent axisymmetric MHD solutions describing flows which originate at the near environment of a central gravitating astrophysical object. The unifying scheme contains two large groups of exact MHD outflow models, (I) meridionally self-similar ones with spherical critical surfaces and (II) radially self-similar models with ...

Beam-plasma instabilities are a key physical process in many astrophysical phenomena. Within the fireball model of Gamma ray bursts, they first mediate a relativistic collisionless shock before they produce upstream the turbulence needed for the Fermi acceleration process. While non-relativistic systems are usually governed by flow-aligned unstable modes, relativistic ones are likely to be domi...

Background The airway epithelium is accepted as an active player in immune responses. Besides its role as physical barrier towards invading pathogens and irritants, epithelium also affects the outcome of the immune response by the production of various pro-inflammatory mediators. We have previously shown that nasal epithelial cells are able to respond to exposure to house dust mite (HDM) allerg...

Classical substrate noise analysis considers the silicon resistivity of an integrated circuit only as doping dependent besides neglecting diffusion currents as well. In power circuits minority carriers are injected into the substrate and propagate by drift–diffusion. In this case the conductivity of the substrate is spatially modulated and this effect is particularly important in high injection...
