the aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. for this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and carbomers such as c974p, c971, c934p and c971 in the range of 0.01-0.1% were adde...

diabetic mellitus (dm) is a major risk factor of morbidity, mortality and economic cost to society. diabetic patients are at risk of having microvascular or macrovascular disorders of diabetes. postoperative anemia have wide spectrum of some early complications that require more care in hospitalization stays. therefore, this study was designed to evaluate effect of preoperative anemia on short-...

Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...

this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...

certain benefits are clearly associated with the use of off-pump coronary artery bypass grafting (cabg) as compared with the on-pump cabg. the superiority is more evident in patients with multiple co morbidities including renal failure.we reviewed the medical records of a 67-year-old male with a past medical history that was significant for multiple cardiovascular diseases and new-onset end-sta...

using a new numerical model, the pump-to-signal relative intensity noise (rin) transfer in singlepumpfiber optical parametric amplifiers for low modulation frequencies is investigated. the model includesfiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practicalcircumstances associated with various applications of fiber optical parametric amplifiers....

the effects of fish weight on salinity tolerance were studied in caspian salmon (salmo trutta caspius) parr. 180 fish (all with 2 years old but with three weights; 5, 15, 25g) were selected and they reared in freshwater (fw) and brackish water (bw; 13ppt salinity) for 10 days. the mrna expression of two α-subunit isoforms of na+, k+-atpase (α1a and α1b) and nkcc co-transporters were studied in ...
