OBJECTIVE To compare fluid thickeners composed of starch polysaccharide (STA), guar gum-based polysaccharide (GUA), and xanthan gum-based polysaccharide (XAN) with the use of a viscometer and a line spread test (LST) under various measurement conditions. METHODS The viscosity of thickened fluid with various concentrations (range, GUA 1%-4%, XAN 1%-6%, STA 1%-7%, at intervals of 1%) was measur...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
Effect of temperature and curing agent type parameters on rheological behavior of binder system based on Hydroxyl terminated Polybutadiene (HTPB) is important in the aspect of production for medium and large-size grains. In this research, the effect of casting temperature 40, 50 and 60 ºC) and chemical structure of curing agents (TDI, IPDI and HDI) on rheological behavior of a binder system bas...
Suimmtl7iarv. The interactions of aflatoxin B, with certain histone fractions and DNA were investigated by means of viscosity measurements and equiilibriuim dialysis. Two main histone fraction,s (F2b and Fl), both lysine-rich, were examined after treatment with the toxin. Fraction 2b and 1 differ in amino acid composition an(l behave differently, in regard to gross conformation, in the presence...
OBJECTIVES This study sought to determine the relationship between blood viscosity and iron deficiency and their impact on symptoms and exercise function in adults with cyanotic congenital heart disease. BACKGROUND Iron deficiency is believed to raise whole blood viscosity in cyanotic congenital heart disease, although available data are inconsistent. METHODS Thirty-nine cyanotic adults wer...
dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. to accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. the scale effect in the spillway modeling, as a...
Preformed Particle Gels (PPGs) treatment is one of the most promising solutions to improve conformance control in mature water flooded oil reservoirs. It is very important to be able to evaluate and predict performance of PPGs in porous media. In this paper, we will first introduce new class of enhanced PPGs designed for harsh reservoir conditions (high salinity and temperature) and then pr...
Dilution is one of the various existing methods in reducing heavy crude oil viscosity. In this method, heavy crude oil is mixed with a solvent or lighter oil in order to achieve a certain viscosity. Thus, precise mixing rules are needed to estimate the viscosity of blend. In this work, new empirical models are developed for the calculation of the kinematic viscosity of crude oil and diluent ble...
