gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
The physiological mechanisms controlling ciliary beating remain largely unknown. Evidence exists supporting both hormonal control of ciliary beating and control via direct innervation. In the present study we investigated nervous control of cilia based locomotion in the nudibranch mollusc, Tritonia diomedea. Ciliated pedal epithelial (CPE) cells acting as locomotory effectors may be electricall...
measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...
Abstract The hydrogeochemical analysis and numerical simulation were conducted to explore the impact of land reclamation on submarine groundwater discharge evolution in seawater intrusion-retreat processes eastern Jiangsu, China. results indicated that origin salt most is saltwater mixing, weathering-dissolution minerals enriches fresh groundwater. path coastal Jiangsu Ca-Na-HCO3-Cl ? Ca-Na-Cl-...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Intracellular Ca(2+) plays a fundamental role in regulating cell functions in pulmonary arterial smooth muscle cells (PASMCs). A rise in cytosolic Ca(2+) concentration ([Ca(2+)](cyt)) triggers pulmonary vasoconstriction and stimulates PASMC proliferation. [Ca(2+)](cyt) is increased mainly by Ca(2+) release from intracellular stores and Ca(2+) influx through plasmalemmal Ca(2+)-permeable channel...
Ca-activated Cl currents are widely expressed in many cell types and play diverse and important physiological roles. The Xenopus oocyte is a good model system for studying the regulation of these currents. We previously showed that inositol 1,4,5-trisphosphate (IP3) injection into Xenopus oocytes rapidly elicits a noninactivating outward Cl current ( I Cl1-S) followed several minutes later by t...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
