objective: the objective of this research is to examine pcb compounds in the persian gulf in the southern pars area. methods: in the research, 6 stations were sampled: asalouyeh port, kangan site, mehr petro kima petrochemical, 4th refinery in southern pasr, taheri port and aria sasol polymer. to sample water in the stations determined, one-liter sampling bottles of dark glass were used. in eac...

electro-facies is a unit of the vertical sediments sequence on the wire-line logs that can be differentiated from the upper and lower units. for detection of the electro-facies interval in kangan and upper dalan formations in south pars gas field, wire-line log and core data analysis (wells a, b, c and d) were used. note, only core data analysis in well a were available. first, thin-sections st...

The corrosiveness of biodiesel affects the fuel processing infrastructure and different parts an internal combustion (IC) engine. present study investigates corrosion behaviour automotive materials such as stainless steel, aluminium, cast iron, copper in 20% (B20) 30% (B30) by volume second-generation Jatropha using immersion test. results were compared with petro-diesel (B0). Various propertie...

Here, Adomian decomposition method has been used for finding approximateand numerical solutions of nonlinear differential difference equations arising inmathematical physics. Two models of special interest in physics, namely, theHybrid nonlinear differential difference equation and Relativistic Toda couplednonlinear differential-difference equation are chosen to illustrate the validity andthe g...

the aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. i will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologica...
