Ground Level Enhancements (GLEs) in cosmic ray intensity observed during the period of 1997-2012 have been studied with energetic solar features and disturbances in solar wind plasma parameters and it is seen that all the GLEs have been found to be associated with coronal mass ejections, hard X-ray solar flares and solar radio bursts. All the GLEs have also been found to be associated with sudden jumps in solar proton flux of energy of ${\geq}60Mev$. A positive correlation with correlation coefficient of 0.48 has been found between the maximum percentage intensity (Imax%) of Ground Level Enhancements and the peak value of solar proton flux of energy (${\geq}60Mev$). All the Ground Level Enhancements have been found to be associated with jumps in solar wind plasma velocity (JSWV) events. A positive correlation with correlation coefficient of 0.43 has been found between the maximum percentage intensity (Imax %) of Ground Level Enhancements and the peak value of solar wind plasma velocity of associated (JSWV) events. All the Ground Level Enhancements have been found to be associated with jumps in solar wind plasma pressure (JSWP) events. A positive correlation with correlation coefficient of 0.67 has been found between the maximum percentage intensity (Imax %) of Ground Level Enhancements and the peak value of solar wind plasma pressure of associated (JSWP) events and of 0.68 between the maximum percentage intensity (Imax %) of Ground Level Enhancements and the magnitude of the jump in solar wind plasma pressure of associated (JSWP) events.
Isolation and Characterization of Steroids of Nutraceutical Value in Physalis minima
Misra Laxmi N.,Lal Pyare,Kumar Devinder The Korean Society of Food Science and Nutrition 2006 Preventive Nutrition and Food Science Vol.11 No.2
There is great demand of nutraceutical secondary metabolites in the world so as to feed the population by improving agricultural production with new varieties of food crops but what is still more important is to add nutrition into the food. Physalis minima, plant of Solanaceae family, contain certain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals that are generally regarded as safe. These chemicals are almost monopoly of the plants of Solanaceae. The leaves, stem and roots of P. minima have been examined to yield several steroids, identification of which has been discussed in this paper. These withasteroids contribute to the potential nutraceutical and health function value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.
