In the crystal structure of the title complex, [Pt(C(5)H(4)NOS)(2)], the Pt atom is coordinated by two O atoms and two S atoms in a cis configuration, forming a distorted square-planar coordination geometry. The mol-ecule exhibits pseudo-C(2v) symmetry and is essentially planar, with a maximum deviation from planarity of 0.0124 (2) Å. The dihedral angle between the two pyridine rings is 5.85 (2)°.
This paper describes an experimental GaAs MESFET static memory cell which overcomes the principal disadvantages of the conventional cell implementation. Cell size is 36x37 μm2 at 0.6 μm gate length. An experimental 32 word x 32bit array has been designed. From simulation results, an address access time of 1ns has been obtained. The cell can be operated at the single supply voltage from 1V to 2V...
The wind is one of the new renewable energy sources that can be used as a source electrical energy. But in nature has speed varies greatly with each time and place. This overcome by using DC-DC Converter tool fuzzy method to produce stable voltage so it becomes usable uses series converters connected Arduino microcontroller. converter circuit this study also sensor feedback for Fuzzy maintain s...
Using rst-principles self-consistent electronic structure theory, we have calculated defect formation energies and defect energy levels in CuInSe2. Contrary to previously accepted assumptions in the analysis of defects in CuInSe2 we nd that (i) it is much easier to form Cu vacancy in CuInSe2 than to form cation vacancies in II-VI's. (ii) Defect formation energies vary considerably both with the...
We report a photoelectron spectroscopy and density functional theory (DFT) study on the electronic and structural properties of Nb(3)(-), Nb(3)O(-), Nb(3)O(2)(-), and the corresponding neutrals. Well-resolved photoelectron spectra are obtained for the anion clusters at different photon energies and are compared with DFT calculations to elucidate their structures and chemical bonding. We find th...
Moraxella catarrhalis (Mx) is a common cause of otitis media and exacerbation of chronic obstructive pulmonary disease, an increasing worldwide problem. Surface proteins UspA1 and UspA2 of Mx bind to a number of human receptors and may function in pathogenesis. Genetic recombination events in the pathogen can generate hybrid proteins termed UspA2H. However, whether certain key functions (e.g. U...
The aim of this study was to assess the tensile bond strength of four adhesive systems to enamel and dentin: Clearfil Liner Bond 2V - C, Prime&Bond NT/NRC - PB, Single Bond - SB and All Bond 2 -AB. For such purpose, 40 sound human molars were selected. Crowns were bisected in a mesiodistal direction and each half was ground until flat enamel (E) or dentin (D) surfaces were obtained. A total of ...
TheKiSS-1 gene has been reported to be ametastasis suppressor gene in humanmelanoma. Thegene product was isolated from human placenta as the ligand of GPR54, a G protein–coupled receptor, and the C-terminally amidated peptide of 54 amino acids is called metastin. The binding of metastin to GPR54 has been shown to inhibit tumormetastasis in some tumor cells; however, its function remains unclear...
چکیده اثر کیفیت بذر روی عملکرد مزرعه ای عدس تحت تیمار های مختلف آبیاری در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه تبریز مورد تحقیق قرار گرفت. یک نمونه بذری از عدس به عنوان شاهد یا توده بذری با کیفیت بالا (1v با 99% قوه زیست) نگهداری گردید و دو نمونه دیگر با محتوای رطوبت 15 درصد به مدت های 18 و 22 روز در دمای 40 درجه سانتی گراد به صورت مصنوعی فرسوده شدند(به ترتیب 2v با 90% و3vبا 80% قوه زیست). ب...
