background: along with the prospers of scientific production there is a need for measuring and evaluation of university’ s scientific productions by means of accepted international indices to make comparison between academic institutions. this study aims to evaluate the scientific production of faculty members affiliated to shahid beheshti university of medical sciences (sbmus) in web of scienc...

Background: Fasciola hepatica is a genus of the trematodes which mainly affects the liver of sheep and these livestock are accidentally infected by eating plants or drinking water contaminated with the metacercariae of this parasite. These parasites can cause considerable economic damage by destroying the liver and bile ducts. OBJECTIVES: The aim of this study was to evaluate the role of ultras...

in this study, the profitability of contrarian and momentum strategies were traded in mid- term based on trading volume. the stocks were categorized into three parts (high, middle and low) at the outset. then, the relationship between excess return with three components such as cross-sectional risk, lead-lag effect and time-series pattern were examined based on jegadeesh and titman approach.the...

the objective of the study was to evaluate the position of patient education measuring knowledge, attitude, and practice (kap) among health care workers (hcws). it is also aimed to emphasize the need for a real position for patient education. this survey was performed among a group of hcws in iran. the scores had an acceptable level. however, nurses, females and younger people received higher s...

The spatial growth of small perturbations developing on a fully developed base flow in a duct with two inhomogeneous cross-flow directions is examined. For a laminar mean flow it is shown that optimally configured vortices at an upstream cross-section induce large transient amplification of a disturbance energy norm downstream. Such a linear growth is a likely initial stage of transition in duc...

In the present work, combustion of vitiated hydrogen jets issuing from differently shaped nozzles is modelled using LES method. We investigate impact nozzle cross-sectional geometries (circular, square, triangular, hexagonal and hexagram) jet Reynolds numbers (Re= 18,000, 20,000 23,600) on flame lift-off height, its structure, locations temperature maxima species distributions. The triangular y...

background and aims: loneliness typically includes anxious feelings. it is particularly relevant to adolescence period. it has effect on physical and mental health. the present study aimed to identify the predictive factors of loneliness among high schools female students.methods: a cross –sectional survey was carried out among high schools female students in ilam during the academic year 2014-...

The non-orthogonal boundary-fitted coordinate transformation method is applied to the solution of steady three-dimensional momentum and energy equations in laminar flow to obtain temperature field and Nusselt numbers in the thermal entry region of straight ducts of different cross sectional geometries. The conservation equations originally written in Cartesian coordinates are parabolized in the...
