abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
in this study, a specific ch4 sensor is fabricated based on interdigitated electrode that modified with core-shell of tungsten carbide/tin oxide (wc/sno2) nanoparticles by wet chemical method in different percents of carbon and tungsten. the morphology of wet chemical-synthesized wc/sno2 core-shell was evaluated by different methods such as patterned x-ray diffraction (xrd), and particle size a...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
literature concerning the effects of ramadan fasting on sports performance presents conflicting results. in this context, some studies reported a significant impairment of sports performance during the month of ramadan. however, other studies suggested that ramadan fasting has no significant effect on physical performance. the discrepancies between the studies could be explained by time-of-day...
Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...
A PVC membrane Fe(III) ion selective electrode has been constructed using a new macrocyclic asmembrane carrier.The electrode exhibits a good potentiometric response for Fe(III) over a wideconcentration range 1.0×10-4 to 1.0×10-1M with a slope 19.4±0.5 mV/decade a and a working pHrange of 6.5-9.0. It has a fast response time ≤30s.The best performance was observed with themembrance having the 30....
