Sci., Vol.29 No.1(Suppl), January 2016, pp.351-355 [(The 1st group irradiated with 25Gy gamma radiation (n=10); the 2nd group irradiated with 50Gy (n=10); the It has long been recognized that understanding the rheological properties of blood is essential to a full understanding of the function of the circulatory system. Given the difficulty of obtaining carefully controlled measurements in vivo, most of our current concepts of the flow behavior of blood in vivo are based on its properties in vitro. Rheological properties of blood after whole body gamma-irradiation Rheological tests were performed in four rigorously defined groups of patients with Raynaud's phenomenon: primary family-related (n = 21), primary family-unrelated (n = 30), 'possible scleroderma' (n = 26), and scleroderma (n = 19). Whole blood and plasma viscosity, and hematocrit were significantly higher in the 'possible scleroderma' group.

Speckle image velocimetry (SIV); Ultrasound agent; Data analysis for ultrasound blood speckles; Viscosity estimation; Variation of hemorheological properties The rheological properties of a fluid have an important role in process development and optimization. Due to its high concentration, frozen concentrated orange juice (FCOJ) shows viscoelastic formed from a solution of proteins and minerals. The rheological properties of blood are influenced by individual characteristics of these components as well as factors such as haematocrit, amongst others [1,2].

In summary, this study revealed positive effects of winter swimming on the rheological properties of blood, manifested by an increase in erythrocyte deformability without accompanying changes in erythrocyte aggregation. PMID: 24577381 thus the adsorption-rheological properties of blood (ARPB) — surface tension (ST), serum viscosity (SV), serum elasticity (SE), serum relaxation (SR), and vis-coelasticity (VE) modulus [5, 6]. The interfacial tensiometry method is used to study the ST of cancer cell cultures as a criterion of their 1976-01-01 1979-04-20 Blood, a valuable by-product of livestock slaughter, has numerous food, industrial, and pharmaceutical uses. Physical and rheological properties, including apparent viscosity, density, surface tension, thermal conductivity, and specific heat, are needed for the design of transport processes and by-product applications such as spray drying, blending, and extrusion.
