the efficiency of diazinon (as insecticides) and nitrate (related to nitrogen fertilizer) removal from contaminated water is investigated through nf membrane technique. the effects of nitrate concentration (40-160 mg/l), diazinon concentration (10-1000 µg/l) and ph (5-9) on the efficiency of a commercial polyamide nanofilter membrane at a constant pressure of (800 kpa) are investigated. the res...
The synaptic vesicle protein synaptotagmin I has been proposed to serve as a Ca(2+) sensor for rapid exocytosis. Synaptotagmin spans the vesicle membrane once and possesses a cytoplasmic domain largely comprised of two C2 domains designated C2A and C2B. We have determined how deep the Ca(2+)-binding loops of Ca(2+).C2A penetrate into the lipid bilayer and report mutations in synaptotagmin that ...
Membrane technology is growing very fast and it is used in several main applications from desalination, water and wastewater treatment to medical, biotechnology and gas separation field. Different membrane processes are applied depending on the applications from more traditional pressure-driven membrane processes (Microfiltration, MF; Ultrafiltration, UF; Nanofiltration, NF) to more advanced on...
INTRODUCTION This review addresses the different prosthetic socket designs for trans-tibial amputees, the biomechanics behind the designs and the current state of the field. Of particular focus is the classic patella-tendon bearing (PTB) socket and the more recent sockets manufactured using pressure casting techniques and the theory, biomechanics and clinical implications of the two designs. Me...
