High Altitude Pulmonary Oedema (HAPO) is the most common challenging emergency at Siachen Glacier. This study was aimed at studying various aspects of Extreme Altitude Pulmonary Oedema (>5500 m/18,000 ft) while correlating it with acclimatization and post acclimatization duration of stay in retrospect and response to HAPO Bag nursing prospectively. All clinical cases of HAPO on Siachen were...
Wireless ad hoc networks are being deployed in a wide range of applications and many of these networks use battery operated nodes. A key requirement for these networks is to maximize the time span when all nodes have sufficient battery charge to participate in communication with other nodes. To meet this requirement, this paper describes a routing strategy that seeks to find the best balance between...
Communication through fading channels with conventional signal constellation has a limitation that the nearby points may lead to wrong symbol detection even if any one dimension fades. This limitation can be overcome by phase rotation of symbols where each symbol is rotated by a rotation matrix. In the new constellation, each symbol attains unique real and imaginary components which imply higher diversity...
The fascinating process of channelling of metabolic intermediates through enzymes is discussed in this article. Often, the active sites of two enzymes that catalyse sequential reactions in a metabolic pathway are connected through an intra-molecular ‘void’ — a sort of tunnel, lined by amino acids through which intermediates pass. Synergy between the subunits leads to a phenomenal increase in the overall...
