hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

Accurate estimation of the state charge (SOC) lithium batteries is paramount to ensuring consistent battery pack operation. To improve SOC accuracy and suppress colored noise in system, a fractional order model based on an unscented Kalman filter H-infinity (FOUHIF) algorithm was proposed. Firstly, discrete equation derived, as per theory calculus. Then, HPPC experiment PSO were used identify i...

leptin, a circulating 16-kd polypeptide consisting of 167 amino acids, appears to be involved in the body weight homeostasis. moreover leptin plays an important role for the reproductive system, early embryogenesis, and fat metabolism during pregnancy and puberty. significant correlations have been found between leptin and sexual hormones, which is a cytokine and has hormonal properties. the ai...

objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

the purpose of this study was to investigate and compare whether the explant supernatants prepared from endometrial tissues during the proliferative phase, secretory phase and early pregnancy differ in immunosuppressive activity. specimens of nonpregnant endometrium from hysterectomies and normal first trimester decidua following elective aspiration termination of pregnancy were obtained. super...

Fuzzy control strategy is developed for the dual-clutch single-axis torque coupling parallel hybrid electric vehicle. In this paper the torque distribution fuzzy controller which has been designed for the hybrid vehicle which is optimized by genetic algorithms. The simulation model of the hybrid vehicle was built upon matlab / simulink and ADVISOR software. Then a fuzzy rules and correspondent ...

let g = (v, e) be a simple graph. hosoya polynomial of g isd(u,v)h(g, x) = {u,v}v(g)x , where, d(u ,v) denotes the distance between vertices uand v. as is the case with other graph polynomials, such as chromatic, independence anddomination polynomial, it is natural to study the roots of hosoya polynomial of a graph. inthis paper we study the roots of hosoya polynomials of some specific graphs.

objective: to investigate the effect of fluoxetine as an ssri on menstrual disorders. materials and methods: in this cross-sectional study 200 women referring to the islamic azad university affiliated hospitals during march 2011- march 2010 were divided into 4 groups. all included patients in this study had the chief complaint of mood disorders in peri- menstrual period. all patients received d...

conclusions according to our results, by omitting probable risk factors of incidence of sore throat and evaluation of role of hormonal changes in women represented in menstrual cycles, there was no significant association between menstrual cycle and sore throat incidence. results of 100 patients, in the first six hours, 51 patients had sore throat and 49 had no pain. during the first 6 hours, 3...
