The article focuses on the spider mites are the most economically important group of mites which cause considerable loss of yield on different crops. It mentions that future work seeks to incorporate discharge-dependent roughness coefficient which will minimize the error in discharge estimation. It also mentions the simple workflow approach with an intuitive graphical interface will help researchers to estimate hydrological hydraulic parameters with ease.

Four unusually large ice-stones (megacryometeors) weighing several kilograms fell in western India during October-November 2010. Samples were retrieved from three fall events. To study the origin and formation of these megacryometeors, d 18O, d D, chemical composition and ?-activity were measured. The range of d 18O-d D is similar to the local meteoric water, suggesting origin from local atmospheric water vapour. The relative humidity at ~4 km altitude was higher during a few days before and after the fall. No ?- activity from cosmogenic radionuclides such as 26Al could be detected in the inherent dust. These studies indicate terrestrial origin of these megacryometeors. [ABSTRACT FROM AUTHOR]
