The amniotic plaques in sheep of the Karagouniko breed
(2008)The structure of amniotic plaques and adjacent epithelium of full term ewes of the Karagouniko breed were studied using scanning electron microscopy (SEM) and light microcopy. The amniotic plaques appeared as cauliflower-like ... -
BaCeO3: Materials development, properties and application
(2014)The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ... -
beta-Lactoglobulin improves liposome's encapsulation properties for vitamin E delivery
(2014)Vitamin E (VE) or alpha-tocopherol is the major fat-soluble antioxidant in the human body. It is a sensitive, easily oxidized in the air, molecule, so it must be protected from pro-oxidant elements which could affect its ... -
Comparison of interleukin-6 and matrix metalloproteinase expression in the subretinal fluid and the vitreous during proliferative vitreoretinopathy: Correlations with extent, duration of RRD and PVR grade
(2014)Introduction: The full extent of IL-6 involvement in PVR pathophysiology has not yet been comprehensively investigated. The aim of this study was the comparison of the IL-6 effect on MMP expression between SRF and the ... -
Computer-aided estimation of acetone, methyl acetate, and chloroform diffusion coefficients in poly(vinyl acetate)
(2003)The diffusion coefficients of acetone, methyl acetate, and chloroform in amorphous poly(vinyl acetate) are estimated using the solvent evaporation method. The evaporation process from polymer solutions, cast in the form ... -
Computer-aided estimation of diffusion coefficients in non-solvent/polymer systems
(2001)Full Paper: A novel method for estimating the mutual and self-diffusion coefficients of a non-solvent/polymer system is proposed in this work. The idea is to stud the evaporation process from non-solvent/solvent/polymer ... -
Ethanol crossover and direct ethanol PEM fuel cell performance modeling and experimental validation
(2006)In the present work, a one-dimension, steady-state and single phase model is developed with the purpose of describing the mass transport within a PtRu/Nafion (R)-115/Pt membrane-electrode assembly and the performance of a ... -
Ethanol crossover phenomena and its influence on the performance of DEFC
(2005)In the present work, Nafion (R) membrane porosity changes were determined in aqueous ethanol solutions with different concentrations by weighing vacuum-dried and ethanol aqueous solution equilibrated membranes at room ... -
Hydrogen production aided by new (1-x) SrTi0.5Fe0.5O3-delta-xCe(0.8)(Sm0.8Sr0.2)(0.2)O2-delta(MIEC) composite membranes
(2014)In the present work, composite materials of the type (1-x)SrTi0.5Fe0.5O3-delta-xCe(0.8)(Sm0.8Sr0.2)(0.2)O2-delta (with x = 0, 0.25, 0.5, 0.75 and 1) are obtained by the two step solid state technique. Their transport ... -
Interleukin-6 and matrix metalloproteinase expression in the subretinal fluid during proliferative vitreoretinopathy: Correlation with extent, duration of RRD and PVR grade
(2012)Purpose: To investigate interleukin (IL)-6 protein levels in the subretinal fluid (SRF) of patients with rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy (PVR); to correlate the IL-6 ... -
Interleukin-6 and the matrix metalloproteinase response in the vitreous during proliferative vitreoretinopathy
(2011)Purpose: To investigate the levels of IL-6 in the vitreous of patients with RRD complicated with PVR and correlate the IL-6 levels with matrix metalloproteinase (MMP)-1,-2,-3,-8,-9 and tissue inhibitor of metalloproteinases ... -
Membrane Processing Technology in the Food Industry: Food Processing, Wastewater Treatment, and Effects on Physical, Microbiological, Organoleptic, and Nutritional Properties of Foods
(2015)Membrane processing technology (MPT) is increasingly used nowadays in a wide range of applications (demineralization, desalination, stabilization, separation, deacidification, reduction of microbial load, purification, ... -
Nonlinear binding of sex steroids to albumin and sex hormone binding globulin
(1997)We have studied the binding of sex steroids to albumin and sex hormone binding globulin (SHBG) using gel filtration chromatography for the separation of the bound from the free fraction of the steroid. It was found that ... -
OLIGOSACCHARIDES IN GOAT MILK: STRUCTURE, HEALTH EFFECTS AND ISOLATION
(2013)Oligosaccharides have been widely recognized for their prebiotic and anti-infective properties. Among the different types of mammalian milk, the one of humans is the richest source of naturally derived oligosaccharides. ... -
Static response and stability of coated microbubbles-multiplicity of solutions and parameter estimation
(2014)The static response of a coated microbubble subject to an external pressure distribution is investigated, in order to identify different response patterns with varying viscoelastic properties of the shell. Theoretical and ...
