In fluorescence fluctuation polarization sensitive experiments, the limitations associated with detecting the rotational timescale are usually eliminated by applying fluorescence correlation spectroscopy analysis. In this paper, the variance of the time-averaged fluorescence intensity extracted from the second moment of the measured fluorescence intensity is analyzed in the short time limit, be...

In this paper we use viscosity solution methods to show that almost integrable Hamiltonian systems are not smoothly integrable at rotation numbers which are exponentially close to resonances.

Nanofluid is prepared through the nanoscale particles suspended in a fluid base and Nanotechnology is a new attempt to investigate the thermal sciences. As a result of huge investment in developed countries on nanotechnology, research on thermal properties of nano-fluids is of particular interest.Due to the usage of nanotechnology to reduce energy waste, in this project CeO2 with EG is used to ...

In recent years, biodiesel has been considered as a good alternative of diesel fuels. Density and viscosity are two important properties of these fuels. In this study, density and kinematic viscosity of biodiesel-diesel blends were estimated by using artificial neural network (ANN). A three-layer feed forward neural network with Levenberg-Marquard (LM) algorithm was used for learning empirical ...

It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

AIMS To investigate the correlation between fibrinogen concentration and plasma and serum viscosity. METHODS Measurements of paired plasma viscosity and serum viscosity were compared in 45 subjects with a considerable range of fibrinogen concentrations and serum viscosity. RESULTS Plasma and serum viscosity correlated well with plasma fibrinogen in cases of normal serum viscosity, but not i...

Abstract: The modeling of the viscous behavior of nanoemulsions and nanosuspensions is discussed. The influences of the viscosity ratio, solvation and aggregation of nanodroplets and nanoparticles on the relative viscosity of nanofluids are considered. The relative viscosity of a nanofluid is strongly affected by solvation of nanoparticles. The scaling of the relative viscosity of nanoemulsions...

Nutrient utilisation and growth performance responses of White Pekin ducks (Anas platyrinchos domesticus) offered diets containing low- or high-viscosity wheat supplemented with xylanase were investigated in two studies. In Expt 1, six diets consisting of low-viscosity wheat or high-viscosity wheat supplemented with 0.0, 1.5 or 3.0 g xylanase (2590 units/g)/kg diet were used in a true metabolis...
