an optimal design and fabrication of compressors requires flow investigation through the compressor components. flow field inside the volute is fully three dimensional and turbulent. better understanding of flow mechanism leads to improve the volute design procedure. in this research the experimental and numerical flow investigation through a radial flow compressor volute are performed to recog...

the acute toxicity of a malaysian crude oil to red snapper, lutjanus argentimaculatus, blacktiger shrimp and penaeus monodon were investigated. the animals were exposed to water solublefractions (wsf) of crude oil in a flow-through bioassay system and the toxicants were analyzed by gaschromatography (gc) and gas chromatography and mass spectrometer (gc-ms). the 96 h lc50 valuesof the wsf of cru...

O social networks greatly facilitate social exchange among friends. At times, for amusement, individuals may be targeted by friends’ playful teases, which often involve exposing individuals’ private embarrassing information, such as information that reveals their past indecent behavior, mischief, or clumsiness. Although individuals sometimes do enjoy the humor, they might also be offended by th...

The use of information technologies (IT) to collect personal health information is growing in popularity via computer-assisted interviewing and a wide variety of healthcare Web sites. However, a review of the literature on computer-assisted interviewing exhibits confounding and equivocal results regarding the effects of IT on individuals’ willingness to disclose socially sensitive health inform...

A numerical investigation was carried out to solve the flow dimensionless partial differential equations through rectangular microchannels. A purely viscous power law <span style="font-size: 10pt; colo...

exergy analysis of a system is a method for recognizing the value and type of system availability against surrounding environment. it also helps to find how macroscopic properties of the system change during a process. this analysis is based on first and second laws of thermodynamics. by exergy analysis proportion of each process in the internal availability transmission and the places of usefu...

objective(s):  the cholinergic system plays an important role in learning and memory. this study investigated the effects of curcumin (turmeric extract) and the cholinergic system and their interaction on memory retention of passive avoidance learning in adult male wistar rats. materials and methods: at first, an injection cannula was implanted in right ventricles of the animals. one week after...
