A descriptive study of isothermal kinetics of diclofenac release from chitosan-g-acrylic acid (Chit-AA) hydrogel and chitosan-g-(acrylic acid-co-[2-(acryloyloxy)ethyl]trimethylammonium chloride) (Chit-AA-AETM) hydrogel was carried out. Isothermal kinetic curves for diclofenac release from both hydrogels in distilled water at various temperatures of 20-42°C were studie...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Salt tolerance of higher plants is determined by a complex set of traits, the timing and rate of evolution of which are largely unknown. We compared the salt tolerance of cultivars of sugar beet and their ancestor, sea beet, in hydroponic studies and evaluated whether traditional domestication and more recent breeding have changed salt tolerance of the cultivars relative to their ancestor. Our ...
