Aims: To study the phosphorus requirement of Rice - zero till maize (Zea mays L.) cropping system on productivity and soil available Phosphorus balance. Study Design: Randomized block design (two factors). Methodology: The field experiment was conducted for two consecutive years at College Agriculture, Rajendranagar, Hyderabad. Levels P2O5 (kg ha-1) applied to rice (5 levels) (3 respectively we...

Potato tubers (Solanum tuberosum L. cv Bintje) were stored at 20 degrees C for 210 days without desprouting to study the lipoxygenase pathway during aging. After 15 days of storage, potato tubers sprouted, while after 45-60 days, apical dominance was lost and multiple sprouts developed. Analysis of the fatty acid hydroperoxides (HPOs) revealed that 9-S-hydroperoxide of linoleic acid (9-HPOD) wa...

BACKGROUND AND PURPOSE Ischemic postconditioning has been found to decrease brain infarct area and spinal cord ischemic injury. In this study, we tested the hypothesis that ischemic postconditioning reduces global cerebral ischemia/reperfusion-induced structural and functional injury in rats. METHODS Ten-minute global ischemia was induced by 4-vessel occlusion in male Sprague-Dawley rats. The...

Phase change materials (PCM) RT-28HC, RT-35HC, and RT-44HC with three different melting temperatures, 29 °C, 36 44 similar thermal properties, are considered. The PCM is oriented from the left to right side of heat sink in its increasing order. fins attached longitudinally, orientation effects studied low (100–500 W/m2) high (1000–5000 fluxes applied on horizontal bottom surface sink. A 2D mode...

Hearts from male rats were incubated at 37 degrees C for variable periods of global ischaemia. Estimation of kinetic parameters of (Na,K)-ATPase at 37 degrees C in the presence of increasing concentrations of ATP revealed a significant decrease of Vmax in the first 15 minutes of ischaemia with further stabilization at the lowest level in 45-60 minutes of ischaemia. The changes in ATP binding si...
