High temporal and inter-individual variation detected in the human ileal microbiota
(Wiley, Hoboken, 2010)
P gt The diversity and temporal stability of the predominant bacteria in the human ileum was studied with the use of ileal effluent samples of seven individuals with Brooke ileostomies. The total number of bacteria within ...
Smart poly(2-hydroxyethyl methacrylate/itaconic acid) hydrogels for biomedical application
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
pH- and temperature-sensitive hydrogels, based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) copolymers, were prepared by gamma-irradiation and characterized in order to examine their potential use in ...
Study on the photocatalytic degradation of insecticide methomyl in water
(Elsevier Science Bv, Amsterdam, 2010)
Photo-Fenton degradation of the insecticide methomyl in water using Fe-ZSM-5 zeolite and AlFe-pillared montmorillonite catalysts under halogen lamp light was studied. The study was performed at room temperature in a glass ...
The influence of aluminium surface pretreatment on the corrosion stability and adhesion of powder polyester coating
(Elsevier Science Sa, Lausanne, 2010)
One of the most important factors in corrosion prevention by protective coatings is the coating adhesion loss under environmental influence. Thus, adhesion strength is often used when characterizing protective properties ...
Densities and Excess Molar Volumes of 2-Butanol + Cyclohexanamine plus Heptane and 2-Butanol + n-Heptane at Temperatures between (288.15 and 323.15) K
(Amer Chemical Soc, Washington, 2010)
The density p and excess molar volumes V-E for 2-butanol + cyclohexanamine + heptane and 2-butanol + heptane have been determined at temperatures of (288.15, 293 15, 298 15, 303 15, 308.15, 313.15, 318 15, and 323 15) K ...
Investigation of gas transport through porous membranes based on nonlinear frequency response analysis
(Springer, New York, 2011)
Theoretical development of a new experimental method for investigation of mass transport in porous membranes, based on the principle of the modified Wicke-Kallenbach diffusion cell and the nonlinear frequency response ...
Volumetric Properties and Spectroscopic Studies of Pyridine or Nicotine Solutions in Liquid Polyethylene Glycols
(Amer Chemical Soc, Washington, 2011)
Densities and molar excess volumes of the solutions of pyridine or nicotine in liquid polyethylene glycol, PEG200 and PEG400, have been determined at several temperatures. The experimental molar excess volumes are negative, ...
The influence of silicon substitution on the properties of spherical- and whisker-like biphasic alpha-calcium-phosphate/hydroxyapatite particles
(Springer, Dordrecht, 2011)
In this work, the influence of the morphology of hydroxyapatite particles on silicon substitution through hydrothermal synthesis performed under the same conditions was investigated. Spherical- and whisker-like hydroxyapatite ...
The effect of deposition temperature on the surface coverage and morphology of iron-phosphate coatings on low carbon steel
(Elsevier, Amsterdam, 2011)
The influence of deposition temperature and concentration of NaNO2 in the phosphating bath on the surface morphology and coverage of iron-phosphate coatings on low carbon steel was investigated. The phosphate coatings were ...
Corrosion stability of polyester coatings on steel pretreated with different iron-phosphate coatings
(Elsevier Science Sa, Lausanne, 2011)
The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was ...
