To elucidate the deleterious effects of excess lead on radish (Raphanus sativus) cv. Jaunpuri plants were grown in refined sand in complete nutrient solution for 30 days. On the 31st day lead nitrate was superimposed at 0.1 and 0.5mM to radish for 65 days. A set of plants in complete nutrient solution was maintained as control for the same period without(More)
Despite some predictions of the total demise of next generation satellite systems, a working Ka-band regenerative satellite system has been built and it is called SPACEWAY TM*. SPACEWAY provides a two-way broadband " Internet in the Sky " IP network over satellite. It utilizes on-board regenerative processing and on-board packet switching with one-hop mesh(More)
Satellite network capacity, adaptability, and responsiveness are enhanced with onboard capabilities for packet switching, bandwidth allocation, and spot-beams which facilitate uplink and downlink spectral reuse. A recent over-the-air (OTA) test of the SPACEWA YM system, a Ka-band regenerative satellite mesh network supporting IP packet services, provides(More)
The achievement of a network-centric battlefield has largely driven the development of satellite communications (SATCOM) on-the-move (SOTM), as a technology solution to facilitate the exchange of rich sources of information amongst geographically-dispersed force elements. While the technical enablers for this concept are rapidly maturing, the operational(More)
