This paper presents the design evolution of drive booster configuration for terrain vehicle to manoeuvre over the roads covered with mud or snow. The proposed design of booster consisted small number of parts whose sizing is accomplished through design calculations. The intended system will take power from engine to do so but in petite proportion. The booster increases the moment of inertia through increment in angular speed of terrain vehicle. Structural design adequacy is assessed using ANSYS commercial finite element analysis software. Available safety margin is extracted through static analysis. The severance of first natural frequency of the intended booster system is ascertained from that of engine by carrying out modal analysis. © 2015.

The plant Justicia gendarussa was investigated for their antioxidant activity. The extractions were subjected to assay by Reducing power, Nitric oxide scavenging activity, DPPH methods for evaluation of anti oxidant activity. Among these Petroleum ether extract of Justicia gendarussa revealed strongest antioxidant activity. The results primarily suggest the presence of potent oxidant inhibitory principles in the leaf of Justicia gendarussa.
