Hard magnetorheological elastomers (h-MREs) are essentially two phase composites comprising permanently magnetizable metallic inclusions suspended in a soft elastomeric matrix. This work provides thermodynamically consistent, microstructurally-guided modeling framework for isotropic, incompressible h-MREs. Energy dissipates such hard-magnetic primarily via ferromagnetic hysteresis the underlyin...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. this review was conducted to introduce and compare the conventi...

in this review the role of cerebrospinal fluid (csf) in mammalian cerebral cortex development has been highlighted. many studies have focused on the potential role of the csf in the developmental process. in particular, the cerebral cortex develops from the germinal epithelium adjacent to the csf. csf contains proteins, growth factors and other neurotrophic factors which are important for neura...

to investigate uterine and serum copper (cu) and zinc (zn) concentrations variation duringthe bovine estrus cycle , 232 blood and genital tract samples were collected from the abattoir inurmia. the phase of the estrous cycle was determined by the examination of the ovaries and theuterine tonicity. of the 46 samples selected for use in the study, 13 were pro-estrus, 10 estrus, 8metestrus, and 15...

introduction: in vitro maturation and development of immature oocytes, as an artificial reproduction technique, is useful especially in women who are affected by cancer and polycystic ovary syndrome. despite using many types of in vitro media, an appropriate environment has not been reported yet. present study was designed to assess the effect of heated human follicular fluid (hhff), which is s...

background: cadmium is an extremely toxic metal with ubiquitous environmental distribution. cadmium is a potent reproductive and developmental toxic agent, and intensive environmental exposure to this substance has been reported among the residents of tehran. in this study, we investigated the correlation between amniotic fluid cadmium levels and the risk of preeclampsia, prematurity and low bi...

background premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on pregnancy outcomes. a diagnostic tool that is non-invasive, specific and quick is needed to predict prom. the purpose of this study was to evaluate the diagnostic power of the vaginal washing fluid prolactin for the diagnosis of premature rupture of membranes and to d...

a frequency-wavenumber-domain formulation is presented in this paper for calculation of the green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. the green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. the solution is in the frequency ...
