background: according to the international reports, brain stroke is the main reason of death and disability. in ischemic stroke, early and precise classification of patients who may profit from conflicting finest therapeutic interference is necessary if enhanced effects in terms of survival are to be talented. due to uncomplicated, easy performance, and inexpensive method the aim of this prelim...

After frame synchronization, individual measurands are identified according to the frame location. The decommutator identifies and extracts embedded asynchronous data stream (EADS) words. Thus PCM Decommutator is a very crucial subsystem in the satellite data acquisition unit of satellite ground station. A PCM decommutator is designed and implemented on a Stratix FPGA. The Hardware design compr...

Simultaneously sensing and resolving the position of measurands along an optical fiber enables numerous opportunities, especially for application in environments where massive sensor deployment is not feasible. Despite significant progress techniques based on round-trip time-of-flight measurements, need bidirectional propagation imposes fundamental barriers to their communication links containi...

Based on Mason’s signal flow graph analysis, an analytical model of the optical mode localization based coupled ring resonators is established. The correctness theoretical proved by simulation. High sensitivity and common-mode rejection can be achieved evaluating modal power ratio from resonant peaks as sensing output. four-port structure, two output spectrum with (asymmetric splitting) symmetr...

This paper presents a review of the recent trends and current state art in application fiber optic Bragg gratings (FBG) sensing technology to condition monitoring (CM) testing practical electric machinery associated power equipment. FBG has received considerable interest this field years, with research demonstrating that flexible, multi-physical, electromagnetic interference (EMI) immune situ m...

aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. this study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘malase saveh’ pomegranates. the results indicated that concentrations of cu in the aril and k, mg, and mn i...

to study changes in concentrations of some biochemical factors of amniotic fluid, 115 normal goat uteri at different stages of pregnancy were collected from slaughterhouse. after expelling of each fetus accompanied by fetal membranes, 10 ml amniotic fluid was taken from amniotic sac for biochemical analysis. then approximate ages of fetuses were calculated by using age estimation formula. at fi...

chlorpyrifos, an organophosphate pesticide, is widely used to control pests in agriculture farms and orchards of fruit trees. in this study, the fish were exposed to sub-lethal concentrations of chlorpyrifos which were determined based on numerical value of 96 h lc 50 . blood was sampled after 10, 20 and 30 days and biochemical parameters including glucose, total protein, albumin, globulin, tri...

polycystic ovarian syndrome is a hetrogenous condition with a broad clinical and pathologic spectrum that may reflect the effects of diverse etiologic factors. polycystic ovarian syndrome is an abnormality in the maturation of the follicles which can result in abnormal composition of follicular fluid. by analysis and comparison of the biochemical composition of human follicular fluid in normal ...

grape seed proanthocyanidin extract (gspe) has a broad spectrum of biologic properties against oxidative stress. this study aimed to investigate the effects of gspe on biochemical factors and antioxidant enzymes of erythrocyte in diabetic rats. diabetes was induced through single injection of streptozotocin (50 mg.kg-1, i.p). forty male sprague-dawley rats were divided into four groups: group 1...
