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...

speciated samples of pm2.5 were collected at the hamshire and orange sites in golden triangle of texas by us epa (environmental protection agency) from july of 2003 to august of 2005. a total of 269 samples for the hamshire site and 293 samples for the orange site with 52 species were measured; however, 22 species were excluded because of too many below-detectionlimit data. among the 22 species...

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...

this study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by azolla caroliniana.  the experimental investigations have been carried out using azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), ph (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). the maximum removal ...
