India is prone to many natural and manmade disasters. Chemical, Biological, Radiological and Nuclear (CBRN) emergencies occur as a result of occupational exposure, fire, industrial explosions, release of toxicants and wastes. CBRN Terrorism is showing its head in many parts of the world and India is at risk too. High visibility events like large public rallies, major sporting events, religious festivals and cultural extravaganzas are all highly vulnerable to CBRN terror strikes. There is an urgent need to educate and train all concerned stakeholders in CBRN risks and threats and to adopt risk mitigation measures. The book brings forth the author's views on CBRN Incident Management in India, especially regarding CBRN governance, response mechanism, special event and critical infrastructure security, CBRN security culture and use of new technologies for effective CBRN risk mitigation. The book intends to acknowledge and extol our strides in this direction and urge all responsible stakeholders to take note and act on the gaps post haste.

The objectives of the program were to develop computational fluid dynamics (CFD) codes and simpler industrial codes for analyzing and designing advanced seals for air-breathing and space propulsion engines. The CFD code SCISEAL is capable of producing full three-dimensional flow field information for a variety of cylindrical configurations. An implicit multidomain capability allow the division of complex flow domains to allow optimum use of computational cells. SCISEAL also has the unique capability to produce cross-coupled stiffness and damping coefficients for rotordynamic computations. The industrial codes consist of a series of separate stand-alone modules designed for expeditious parametric analyses and optimization of a wide variety of cylindrical and face seals. Coupled through a Knowledge-Based System (KBS) that provides a user-friendly Graphical User Interface (GUI), the industrial codes are PC based using an OS/2 operating system. These codes were designed to treat film seals where a clearance exists between the rotating and stationary components. Leakage is inhibited by surface roughness, small but stiff clearance films, and viscous pumping devices. The codes have demonstrated to be a valuable resource for seal development of future air-breathing and space propulsion engines.
