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...

Extraction-separation of Eu(III) and Th(IV) ions from nitrate media into the ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate by a phosphorylated salen extractant, bis(chlorophosphoryle)decahydro-2,4-di(2-hydroxyphenyl)benzo[d][1,3,6]oxadiazepine (DPO), is investigated. It is found that Eu(III) ions are extracted via a solvation mechanism, and the extraction of Th(IV) i...

Sound source separation is the of targeted sounds from a noisy environment, which plays an important role in signal processing and has been studied extensively. However, most these researches only extract audio information for processing, ignoring visual information, resulting waste feature information. In addition, some researchers have fused extracted features but not noticed weights differen...

Fins, wings, blades and sails can generate lift drag in both attached separated flow conditions. However, the common understanding of generation mechanism holds only for In fact, when massive separation occurs, underlying assumptions thin airfoil theory lifting line are violated concept bound circulation cannot be applied. Therefore, there is a need to develop an intuitive force that does not r...
