density (r/g cm-3) and viscosity (h/10-2gcm-1s-1=1centipoise,cp) of guanosine monophosphate (gmp) and adenosine triphosphate (atp) referred to as nucleotide, and 2-deoxy adenosine (doa) and thymidine (tmd) as nucleoside along with their integral furanose sugar, 2-deoxy ribose (dor) from 0.0004 to 0.0014mol kg-1 solution have been measured at 288.15, 293.15 and 298.15k at atmospheric pressure. t...

the main purpose of the present study is to investigate the effect of air drying, freeze drying and vacuum drying methods on viscosity and gelation of lipidium perfoliatum seed gum. results showed that the viscosity values of samples varied from 0.31 to 1.26 pa.s at (shear rate = 12.23 s-1) and control sample gum exhibited the highest viscosity. apparent viscosity was decreased by all of drying...

in this study, effects of multi walled carbon nanotubes and temperature on rheological behavior of engine oil (10w40) have been examined. for this purpose, the experiments were carried out in the temperature range of 5-55°c for several suspensions with solid volume fractions of 0.025%, 0.05%, 0.1%, 0.25%, 0.5% and 0.75%. the viscosity of all samples was measured in the shear rate range of 666s-...

Prediction of the apparent viscosity of a slurry suspended fine particles is important for developing slurrytreating processes. After Einstein’s formulation for the apparent viscosity of a dilute, completely dispersed slurry, several viscosity equations were proposed. However, viscosity depends not only on the volume fraction of solid particles but also on many factors such as particle shape, p...

−− The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when nonNewtonian fluids are tested in this device, difficulties appear to determine the apparent viscosity. Thus, conventional rheometric calculations cannot be applied directly to experimental data provided by the FCV in order to obtain the apparent viscosity function...

in the first experiment, the nitrogen corrected apparent metabolizable energy (amen) and nutrients apparent digestibility of full fat soybean (ffsb) extruded at 145, 155 (common temperature) and 165 o c were evaluated. the corn-soy based diets were replaced with zero, 7.5, 15 and 22.5 % of each ffsb extruded at three temperatures during 15-21 d of age and amen and nutrients digestibility of eff...

Since alterations in cell-plasma ratios are of paramount importance in the assessment of periplieral resistance, a study of pressure-flow relations was made in which blood having wide hematocrit values was perfused through a dog's hind limb in which collateral circulation has been excluded. When vessels were moderately dilated by denervation, the relative apparent viscosity was not affected by ...
