Chitosan is a natural polycationic linear polysaccharide derived from chitin.The HERBAL FIBRBLEND RASPBERRY low solubility of chitosan in neutral and alkaline solution limits its application.Nevertheless, chemical modification into composites or hydrogels brings to it new functional properties for different applications.Chitosans are recognized as
Self-contained hydraulic cylinders have gained popularity in the recent years but have not been implemented for high power articulated hydraulic manipulators.This paper presents a novel concept for an electro-hydrostatic actuator applicable to large hydraulic manipulators.The actuator is designed and analyzed to comply with requirements such as loa
This note describes a simple Eye Care procedure for removing unphysical temporal discontinuities in ERA-Interim upper stratospheric global mean temperatures in March 1985 and August 1998 that have arisen due to changes in satellite radiance data used in the assimilation.The derived temperature adjustments (offsets) are suitable for use in stratosph
Horizontal wells open hole staged fracturing technology has become an important technology of horizontal well PLUS EPA increase production.The ball seat is an important part of the whole process, directly related to the effect of fracturing.Established a geometric model for the horizontal open hole staged fracturing ball seat, used FLUENT software
