one of the models that can be used to study the relationship between boolean random sets and explanatory variables is growth regression model which is defined by generalization of boolean model and permitting its grains distribution to be dependent on the values of explanatory variables. this model can be used in the study of behavior of boolean random sets when their coverage regions variation...

In vivo measurement of cerebral arterial and venous volume fractions is important to the understanding of brain physiology and function. By using an intravascular perfluorocarbon and 19F NMR at 4.7 T, regional arterial and venous volume fractions from an intact rat brain were resolved based on the pseudodiffusion coefficients, which were (33 +/- 7) x 10(-3) and (0.45 +/- 0.13) x 10(-3) mm(2)/se...

The selectivity and range of energies offered by specific biological interactions serve as valuable tools for engineering the assembly of colloidal particles into novel materials. In this investigation, high affinity biological interactions between biotin-coated "A" particles (RA = 0.475 microm) and streptavidin-coated "B" particles (RB = 2.75 microm) drive the self-assembly of a series of bina...

Magneto-active polymers (MAPs) are revolutionising the fields of material science and solid mechanics as well having an important presence in bioengineering community. These composites consist a polymeric matrix (i.e., elastomer) filled with magnetic particles iron particles). When bonded together, these two phases form continuum that, under application external field, mechanically reacts leadi...

The buoyancy-driven boundary-layer flow from a heated horizontal circular cylinder immersed in a water-based alumina (Al2O3) nanofluid is investigated using variable properties for nanofluid viscosity. Two different viscosity models are utilized to evaluate heat transfer enhancement from a cylinder. Exact analytic solutions of the problem are attained employing a novel...

Objective(s): The purpose of this research is to study the effect of beta spectrum on absorbed fraction ( ) and to find suitable analytical functions for beta spectrum absorbed fractions in spherical and ellipsoidal volumes with a uniform distribution for several radionuclides that are commonly used in nuclear medicine.Methods: In order to obtain the beta particle absorbed fraction, Monte Carlo...

We investigate the statistical distribution for ideal Bose gases with constant particle density in 3D box of volume V=L3. By changing linear size L and imposing different boundary conditions on system, we present a numerical analysis characteristic temperature condensate fraction find that smaller is efficient to increase fraction. Moreover, there singularity under antiperiodic condition.
