The most important reason for the design of curved tubes is increasing the heat transfer between the fluid and the wall which has provided many applications in various industries such as air conditioning, micro-electric, heat exchangers and etc. The aim of this study is numerical investigation of nano fluids flow in spiral tubes with injection of base fluid in different Reynolds numbers. Accord...

conclusions according to our results, the infusion of one liter normal saline will cause a statistically significant decrease only in bd, after one hour, in patients with moderate to severe iss. the changes in sbp, pr, cvp and also ph, hco3 and hb were not statistically remarkable. background the management of trauma patients is often difficult. the american college of surgeons suggests using a...

salmonella is a gram-negative, non-spore forming facultative anaerobic, motile bacilli. in developing countries, non-typhoidal salmonella (nts) accounts for the steadily increase in the proportion of human infections in recent decades. the clinical presentations of non-typhoidal salmonella infection are protean, including gastroenteritis (the most common one), bacteremia, septic arthritis, oste...

abstract background: the fear of aspiration of gastric contents and its life‑threatening disadvantages in patients have encouraged many medical practitioners to follow conservative policies for clear fluid/liquid and solid intake from midnight to the time of surgery. these policies have been pursued more severely in case of pregnant women, leading the physicians to follow “nil per os” policy. t...

this study is considering a micropolar fluid flow over a porous stretching sheet in the presence of thermal radiation and uniform magnetic field. the effects of local variation in thermal conductivity of micropolar fluid on heat transfer rate from the sheet are investigated; besides, the impacts of radiation, magnetic field and porous sheet on variations of thermal boundary layer thickness are ...

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 ...

burkitt's lymphoma is a lymphatic tumor classified as non-hodgkin lymphoma with small non cleaved cells. the disease has an incidence of two cases per million patients in north america, and usually present with an intra-abdominal tumor, or enlarged cervical lymph nodes. massive amounts of peritoneal and plural fluid is rarely seen in these patients. a three year-old girl presented with massive ...

among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. in this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. al...

background: nephrotoxicity is one of the major side-effects of cisplatin that has been seen in about 20% of treated patients. the aim of this study was to assess the effectiveness of a forced hydration protocol comprised of isotonic saline, potassium chloride (kcl) and magnesium sulfate (mgso4) on prevention of cisplatin nephrotoxicity. methods: this cross sectional prospective study was perfor...

to investigate uterine and serum ca++ and mg++ variations during the estrous cycle in the bovine, 66 genital tracts and blood samples were collected from urmia abattoir, urmia, iran. the phase of the estrous cycle was determined by examination of the structures present on ovaries and uterine tonicity. of the collected samples, 17 were pro-estrus, 12 estrus, 14 metestrus and 23 diestrus. the ute...
