background: one important factor in growth, progress, and increase in work efficiency of employees of any enterprise is to make considerable effort. supreme leader of the islamic republic of iran also addressed the issue of need for more efforts. the goal of this study was to determine the association of perceived organizational justice and organizational expectations with efforts of nurses to ...
the majority of coronary artery fistulas (cafs) are congenital. the anomaly accounts for 0.4% of congenital heart defects and approximately 50% of pediatric coronary vasculature anomalies. twenty percent of people with congenital cafs have other concomitant cardiac anomalies, most frequently aortic and pulmonary atresia and patent ductus arteriosus. it is worthy of note that caf with the tetral...
In this work, the rheological parameters such as yield stress, viscosity coefficient and power law index were obtained for a double-base propellants and modified double-base propellants formulations using the Squeeze flow rheometric method. Squeeze Flow test was used to investigate the rheological behavior without wall slip condition, and to determine the temperature dependency of fluidity in d...
The purpose of this paper is to introduce the concept of soft double fuzzy semi-topogenous order. Firstly, we give the definition of soft double fuzzy semi-topogenous order. Secondly, we induce a soft double fuzzy topology from a given soft double fuzzy semi-topogenous order by using soft double fuzzy interior operator.
intensive induction therapy-in acute myeloid leukemia (aml), as in some other systemic malignancies- is a strategy fundamentally different from post-remission strategies. approaches like consolidation treatment, prolonged mainte nance, and autologous or allogeneic transplantation in the first remission are directed against minimal residual disease with a malignant cell population having survive...
introduction tetralogy of fallot (tof) in the absent of pulmonary valve is a rare congenital anomaly (3%of tof patients). case presentation we are presenting an 18- year-old male with history of dyspnea on exertion and cyanosis since childhood. despite the diagnosis of congenital heart disease, no intervention was done due to his poor socioeconomic culture. at age of 18, he referred to our cent...
numerical study of double-diffusive natural convective heat transfer in a curved cavity filledwith a porous medium has been carried out in the current study. polar system has beenselected as coordinate system. as a result, all equations have been discredited in r and θdirections. brinkmann extended darcy model has been utilized to express fluid flow inporous matrix in the enclosure. smaller and...
in this paper, based on cas wavelets we present quadrature rules for numerical solution of double and triple integrals with variable limits of integration. to construct new method, first, we approximate the unknown function by cas wavelets. then by using suitable collocation points, we obtain the cas wavelet coefficients that these coefficients are applied in approximating the unk...
مدلهای تحلیلی و عددی متعددی برای سفره های کارستی در منابع مختلف گزارش شده است . بر خلاف استفاده گسترده از مدلهائی با تخلخل ساده، در سفره های کارستی، مدلهای تخلخل دوگانه (dcep) بندرت مورد استفاده قرار گرفته اند. از آنجائی که سفره های کارستی به سفره هائی با جریان افشان (diffuse flow)، مجرائی (conduit flow) و افشان-مجرائی (mixed flow) تقسیم بندی می شوند، مدلهای dcpe برای سفره های کارستی مناسب ترند...
