Nowadays, light weight and high strength metals are being used in various industries such as automotive and aerospace. Using aluminum-magnesium alloys is an efficient way to reduce the weight of a specific part. These alloys have poor formability in room temperature thus they should be formed at elevated temperature. Warm hydroforming and hot metal gas forming are conventional methods to form ...
nowadays, compressible flow transmission pipelines are used in many industrial processes. pipelines in chemical processes, gas turbine power plants, natural gas transmission lines, and high pressure steam transmission pipelines are some industrial examples. therefore, learning the manner of treatment of a transient compressible fluid flow in pipelines with junctions and branches is important. i...
in this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. to analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...
background: the effective therapeutic dose of pralidoxime methylsulphate for organophosphate (op) poisoning is necessary to be clarified. this study was designed to comparatively assess the blood level of pralidoxime (bpl) and clinical outcomes in op poisoned patients treated with intermittent dosing and patients treated with continuous infusion. methods: this was a prospective, open labelled, ...
abstract background and objective: measurement of amino acids is an important tool for metabolic studies and evaluation of patients’ clinical condition. the aim of this study was to analyze the plasma amino acids using reverse phase high performance liquid chromatography techniques (rp-hplc) with pre-column derivatization by o-phthalaldehyde (opa) in combination with 3- mercaptopropionic...
Background: Nowadays, high blood pressure is the most important risk factor for heart disease, stroke and kidney diseases and education is one of the most effective factors that reduces high blood pressure. This study aimed to determine the effect of education on knowledge, attitude and preventive behaviors of high blood pressure based on group discussion in women 20-49 years old Islamshahr Cit...
in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...
The aim of this study was to determine the effect of secondary task relevant and non-relevant to the free throw basketball skill on the free throw accuracy of basketball skilled players in choking under pressure. Twenty right-handed female players (aged 18-30) each with at least three years of experience in basketball took part study after completing the Sport Competition Anxiety Test (SCAT), A...
