Three methods for improved deresination of sulphite pulps were evaluated, namely, alkaline washing, enzyme treatment, and pulp fractionation. Alkaline washing appears to come at a high cost, because caustic is expensive and affects cellulose chain length, as indicated by lower viscosity of the pulps. Thus this is not a viable option for pulps that are sensitive to changes in viscosity. Enzyme t...

Regional cerebral blood flow measurements and neuropsychological testing were conducted before and after venesection on 6 patients with polycythemia secondary to chronic obstructive pulmonary disease. Venesection resulted in lowered viscosity and hematocrit, and an accompanying improvement in cerebral perfusion and mental function. Blood flow was significantly increased in the left cerebral hem...

2014 Intrinsic viscosity measurements have been performed on polystyrene-cyclohexane system as a function of temperature T (T ~ 03B8 and as a function of molecular weight (8.2 x 104 ~ Mw ~ 2.06 x 107) .The expansion factor 03B13~ = [~]/[~03B8] of the intrinsic viscosity [~] scales with the reduced variable (T 2014 03B8/T) · ~Mw. For (T201403B8/T) ” ~Mw ~ 2014 40, the intrinsic viscosity of a co...

The effect of temperature-dependent viscosity on heat transfer over a continuous moving surface with variable internal heat generation in micropolar fluids is studied. The fluid viscosity is assumed to vary as inverse linear function of temperature. The governing equations are transformed into dimensionless forms using the stream function and suitable variables then solved numerically using the...

Serial blood rheologic measurements were made in 25 patients with acute myocardial infarction; measurements included blood and plasma viscosities, hematological data and plasma protein concentrations. The blood viscosity was elevated on admission and for more than 21 days after acute myocardial infarction. However, the cause of the elevated viscosity was changed as a function of time after acut...

Acute kidney injury (AKI) occurring in patients admitted to the ICU may result in impaired renal function on long-term follow-up after ICU discharge. The damage induced by subclinical or manifest episodes of AKI may, in fact, produce an irreversible loss of a variable amount of renal mass with deleterious effects on overall renal function. This may be the case even though baseline glomerular fi...

A simple approach to the estimation of the median residual lifetime is proposed for a single group by inverting a function of the Kaplan-Meier estimators. A test statistic is proposed to compare two median residual lifetimes at any fixed time point. The test statistic does not involve estimation of the underlying probability density function of failure times under censoring. Extensive simulatio...

Erythrocytes and plasma proteins contribrelated (p < 0.001) with the plasma ute to viscosity of blood. Therefore, blood macroglobulin concentration in g/100 ml. viscosity was measured in 16 persons with The plasma of patients with macroglobumacroglobulinemia with a cone-plate vislinemia is a non-Newtonian fluid, but at a cometer at defined shear rates. In each given shear rate the plasma viscos...
