research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening ...

The California Mastitis Test has previously been adapted for use in an inline, cow-side sensor and relies on the fact that the viscosity of the gel formed during the test is proportional to the somatic cell concentration. In this paper, the use of capillary and rotational viscometry was compared in light of the expected rheology of the gel formed during the test. It was found that the gel is no...

background: we aimed to compare the effect of albumin 5% in half normal saline (half ns) versus normal saline (ns) infusion on the plasma viscosity in the near-normal physiological condition. according to the high oncotic pressure of albumin along with prolonged half-life of its molecules in comparison to ns in the intra-vascular compartment, it has been proposed that a more significant reducti...

Theoretical and experimental analyses of a cell that measures the viscosity of liquids using longitudinal to shear wave mode conversion are presented. The measurement method is based on the determination of the complex reflection coefficient (magnitude and phase) of shear waves at a solid-liquid interface. The cell is composed of an ultrasonic transducer, a water buffer, an aluminum prism, a PM...

We evaluated adhesion strength to acrylic resins under various experimental conditions and viscosity of 4 cream-type denture adhesives and 2 mouth moisturizers. The viscosity was determined by a sine-wave vibro viscometer. The adhesion strength tests were performed with 2 resin plates at a universal tester. In Method A, various constant thicknesses of material layer were tested and tensile stre...

We have developed a label-free viscosity-based DNA detection system, using paramagnetic beads as an asynchronous magnetic bead rotation (AMBR) microviscometer. We have demonstrated experimentally that the bead rotation period is linearly proportional to the viscosity of a DNA solution surrounding the paramagnetic bead, as expected theoretically. Simple optical measurement of asynchronous microb...
