power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The effect of sodium on the absorption of L-alanine in vivo was tested by measuring the absorption of L-alanine from Thiry-Vella loops in dogs. Solutions containing L-alanine (10 or 50 mM) sodium at concentrations of 0, 74, or 145 m-equiv/1 and mannitol, as needed to maintain isotonicity were instilled into the loops for 10 minutes. Similar studies were done with L-alanine 50 mM and either 0 or...
The present investigation was designed to develop, characterize and evaluate mucoadhesive microcapsules of isoniazid employing various mucoadhesive polymers for prolonged gastric intestinal absorption. Sodium alginate is an anionic polymer which can be easily cross-linked with calcium chloride. This is because the calcium ions are bound to carboxylate residues of both mannuronic acid and glucou...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Background and aims: Bread is considered as one of the important sources of sodium in the Iraniandiet and salt is the main source of sodium, which is used to produce bread. The assessment of dietaryintake is a reliable method that shows nutritional problems in the community. Therefore, the purposeof this study was to evaluate the intake of salt, sodium, and potassium through b...
Appropriate criteria and methods are required to assess desertification potential in various ecosystems. This paper aimed to assess desertification levels in Segzi plain located in east part of Isfahan, with a focus on soil quality criteria used in MEDALUS model. Bayesian Belief Networks (BBNs) were also used to convert MEDALUS model into a predictive, cause and effects model. Soil samples were...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
in this study, vanadium recovery from the steelmaking converter slag was studied. salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. ground slag was roasted after mixing with determined quantities of sodium carbonate. the effect of time and temperature of roasting and sodium carbonate content were studied. the optimum temperatu...
The effect of intravenous vasoactive intestinal polypeptide (VIP) on normal transport mechanisms in the human jejunum in vivo was examined with the triple-lumen, steady-state perfusion technique. By using special test solutions that revealed different aspects of jejunal transport, we were able to evaluate the effect of VIP on specific transport processes, such as active bicarbonate absorption, ...
