Abstract

Complexes of 2-(3-propionic acid) thio-5-phenyl-1,3,4-oxadiazole with Mn(II), Fe(II), Co(II), Ni(II), Cd(II), Pb(II) and Ag(I) have been synthesized and characterized on the basis of physicochemical investigations including infrared and electronic spectroscopy, magnetic moment measurements, molar conductance and elemental analysis. The have been assigned the formula: [M(OXP)(H2O)3]Cl; where M=Mn(II), or Fe(II), [M(OXP)2], Where M=Mn(II), Fe(II), Co(II) and Ni(II), [M(OXP)(H2O)]Cl; where M= CO(II), Ni(II), Cd(II) and Pb(II) and [Ag(OXP)] (NO3). Infrared spectral data suggest that the ligand OXP: behaves as a, monobasic tridentate ligand with N,S,O donor sequence towards the metal ions expect the silver (I); it acts as neutral bidentate ligand coordinating via N,S atoms. On the basis of the above physicochemical data,octahedral, tetrahedral and non linear geometries were assigned for the complexes.The ligand and its complexes were screened for their antifungal activities against two species of fungi, Trichoderma and Aureobasidium; and it was found that the complexes possess certain degree of activity

Abstract

Kirkuk gas turbine power plant is supplied by the gaseous fuel from north gas company. The results showed that the theoretical efficiency of the unit is a function for two parameters; the compressor input temperature and the pressure ratio rp . So, the pressure rp ratio depends directly on the compressor input temperature. If the net work of the unit Wnet (Wt - Wc) is taken to be an index for the performance, the efficiency ƞ will be more in summer than that in winter because of the considerable reduction in compressor work Wc , while if the specific energy produced (or consumed specific fuel SFC) is taken as an index for the performance; the actual efficiency ƞac is more in winter since the specific energy produced in winter is greater approaching (4.5 kW.hr.m-3), while it did not exceed (2.8 kW.hr.m-3) in summer, this belong to the performance improving as the load increases approaching the design load, this is prevailing on the power plant operated by the diesel, heavy fuel or crude oil.
