The rheology of milk powder suspensions is investigated up to very high concentrations, where structural arrest occurs. The main component of the milk powder investigated is casein, so that the suspensions can be regarded as casein suspensions. Four concentration regimes are identified. For effective casein volume fractions less than 0.54 the concentration dependence of the zero-shear viscosity...

Accuracy in in vivo quantitation of brain function with positron emission tomography (PET) has often been limited by partial volume effects. This limitation becomes prominent in studies of aging and degenerative brain diseases where partial volume effects vary with different degrees of atrophy. The present study describes how the actual gray matter (GM) tracer concentration can be estimated usi...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

resonance light scattering (rls) intensity of silver nanoparticles in the presence of sodium dodecylsulphate was quenched on addition of sulfasalzine. the quenching extent was shown to be proportional to the sulfasalazine concentration. effect of different parameters such as ph, volume and kind of buffer, silver nanoparticles concentration, sodium dodecylsulphate (sds) concentration, and waitin...

Plasma aldosterone concentration can increase in anephric man during hemodialysis despite the lack of kidneys to produce renin. Because the metabolic clearance rate of aldosterone does not change during hemodialysis, aldosterone secretion must increase in response to sodium depletion, volume depletion, or both. This study was designed to determine the relative influence of sodium and volume dep...

one way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. in the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. in this work, the performance of water / iron oxide nanofluid in a double...

UNLABELLED The aim of the present study was to investigate asialoglycoprotein receptor (ASGP-R) status in tumor-bearing livers and early after their sectorial resection employing 99mTc-DTPA-galactosyl human serum albumin (99mTc-GSA) dynamic SPECT. METHODS Ten normal liver controls and 44 liver tumor patients who underwent sectorial hepatectomy were included in the study. 99mTc-GSA dynamic SPE...

Microsphere concentrations are needed to assign equivalent reference fluorophores (ERF) units to microspheres used in quantitative flow cytometry. A flow cytometer with a syringe based sample delivery system was evaluated for the measurement of the concentration of microspheres contained in a vial of lyophilized microspheres certified by BD Biosciences to contain 50,600 microspheres. The concen...

The initial soil penetration of Premise 75 and Termidor SC, containing imidacloprid and fipronil, respectively, were tested in laboratory columns of five different soils. Three combinations of application concentration and volume were used: double the recommended active ingredient concentration at one half the recommended volume (DR), the full concentration and volume (FR), and one half the con...

Quantification of -aminobutyric acid (GABA) concentration using localized MRS suffers from partial volume effects related to differences in the intrinsic concentration of GABA in grey matter (GM) and white matter (WM). These differences can be represented as a ratio between intrinsic GABA in GM and WM, rM. Individual differences in GM tissue volume can therefore potentially drive apparent conce...
