the present study investigated no3- and br- contamination in groundwater of arak aquifer of markazi province. correlation and factor analysis were used to detect interrelation and sources of concentration of no3- and br- ions and others physicochemical variables. no correlation was observed between no3- and others contents, but positive correlation was identified between br- with other major va...

introduction: secondary radiation such as photoelectrons, auger electrons and characteristic radiations cause a local boost in dose for a tumor when irradiated with an external x-ray beam after being loaded with elements capable of activating the tumor, e.g.; i and gd. materials and methods:  in this investigation, the mcnpx code was used for simulation and calculation of dose enhancement facto...

in this paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...

conclusions this study shows that bdnf and ngf expression decreases in diabetic neuropathy. however, this decrease can be reversed through endurance training. these results also indicate that endurance training may have a potential role in compensating for neurotrophin deficiency following diabetic neuropathy. objectives this experimental study was designed and carried out at the tarbiat modare...

background one of the main challenges in skin flap surgery is tissue ischemia and following necrosis. the present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. methods thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal random-pattern skin ...

the problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. by using the fourier transform the stress fields are obtained for a functionallygraded strip containing a screw dislocation. the stress components reveal the familiar cauchy singularity at thelocation of dislocation. the solution is empl...
