objective cerebrospinal fluid (csf), its secretion, circulation and absorption have been the subject of recent researches. there is a general agreement that the main site of csf secretion is in the choroids plexus. however, the main absorption site is controversial. some believe that arachnoid granulations are the principle sites of csf absorption. in this study, different locations of csf abso...

background: receptor activator of nuclear factor kappa b ligand (rankl) is one of the key cytokines in the induction of osteoclastogenesis both in vitro and in vivo.several reports indicated the presence of srankl in gingival crevicular fluid of patients with periodontal diseases. objective: to determine the presence of rankl in peri-implant crevicular fluid samples of implants with peri-implan...

enterobius vermicularis is a nematod of large intestine in man. extra intestinal localization of this parasite is rare. a 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. in laboratory examination of cerebrospinal fluid (c.s.f), the appearance was red, albu-min level was high and the glucose showed normal value. haematoxylin and eosin stained slides pr...

Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow, and fluid pressure on the SP is investigated by applying the Discrete Element Method (DEM). Parametric studies show that fluid velocity is red...

in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...

an in vitro experiment was conducted to study the effect of non-fiber carbohydrates (nfc) on ruminaldisappearance kinetics of dry matter (dm) and neutral detergent fiber (ndf) of alfalfa hay, wheat bran andunmolassed sugar beet pulp. non-supplemented or nfc supplemented samples [70 mg/g dm of each feedsample as sucrose (su) or starch (st) or su + st as 1:1] were incubated in bottles containing ...

neonatal hypoglycemia is common and its prompt ‎management is important to reduce neurological sequelae. to determine the effect of two different glucose concentrations of intravenous (iv) fluid ‎therapy in the incidence of hypoglycemia in sick premature infants, 200 preterm infants ‎weighing 1500-2500 g were selected and randomly assigned into two groups. ‎group 1 received 10% dextrose in wate...

The rheological regulation of the “three high” (high temperature, high density and high salinity) water-based drilling fluid is a worldwide problem due to the combined influence of temperature, solid content and salinity. This paper investigates the factors and regulation methods about rheological property of “three high” water based drilling fluid, and the effects of clay, salinity and weighti...

In this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(V/V) percent of the reports. The overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...
