The thermal degradation of aqueous polyurethanes with catalysts of different selectivity
(Elsevier Science Sa, Lausanne, 2007)
The thermal,ability of aqueous polyurethanes has been measured by applying the thermogravimetric analysis, The aqueous polyurethanes (aqPUR) with catalysts of different selectivity have been studied by use of the dynamic ...
Survival of listeria monocytogenes and Escherichia coli O157 : H7 during Sauerkraut fermentation
(Int Assoc Food Protection, Des Moines, 2005)
Sauerkraut was produced from shredded cabbage, as is typical in the United States, and from whole head cabbages, which is a traditional process in parts of Eastern Europe. The sauerkraut was inoculated with five strain ...
Permeate flux and fouling resistance in ultrafiltration of depectinized apple juice using ceramic membranes
(Elsevier Sci Ltd, Oxford, 2003)
Raw depectinized apple juice was clarified in a laboratory scale ultrafiltration system using ceramic tubular membranes (Tech-Sep Carbosep) with a molecular weight cut-off of 300,000, 50,000, and 30,000 Da. The experiments ...
Boron uptake by the root cortex symplast of tomato and pea plants: evidence for low-boron-induced active transport
(Csiro Publishing, Clayton, 2007)
The objective of this research was to test the hypothesis of the existence of an active boron ( B) uptake into the cortical cells induced by low B supply. The uptake of B was characterised in two tomato ( Lycopersicon ...
Synthesis and characterization of new Pt(II) and Pd(II) complexes with 2-quinolinecarboxaldehyde selenosemicarbazone: Cytotoxic activity evaluation of Cd(II), Zn(II), Ni(II), Pt(II) and Pd(II) complexes with heteroaromatic selenosemicarbazones
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2009)
New complexes of Pt(II) and Pd(II) with 2-quinolinecarboxaldehyde selenosemicarbazone were synthesized and characterized by elemental analysis, NMR and IR spectroscopy and molar conductivity measurements. The assumed ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Depleted uranium mobility and fractionation in contaminated soil (Southern Serbia)
(Springer Heidelberg, Heidelberg, 2008)
Goal, Scope and BACKGROUND: . During the Balkan conflict in 1999, soil in contaminated areas was enriched in depleted uranium (DU) isotopic signature, relative to the in-situ natural uranium present. After the military ...
Impact of the population of spoilage microflora on the growth of Listeria monocytogenes on frankfurters
(Int Assoc Food Protection, Des Moines, 2006)
Approximately 100 CFU/cm(2) of a five-strain mixture of Listeria monocytogenes was coinoculated onto frankfurters with three different concentrations (10(2), 10(4), and 10(6) CFU/cm(2)) of an undefined spoilage microflora ...
Comparative study of batch and continuous multi-stage fixed-bed tower (MFBT) bioreactor during wine-making using freeze-dried immobilized cells
(Elsevier Sci Ltd, Oxford, 2009)
A freeze-dried immobilized biocatalyst produced by immobilization of Saccharomyces cerevisiae AXAZ-1 yeast cells on gluten pellets and subsequent freeze-drying was used in a multistage fixed-bed tower (MFBT) bioreactor for ...
Transformation of petroleum saturated hydrocarbons during soil bioremediation experiments
(Water, Air, and Soil Pollution, 2008)
This paper presents transformations of saturated hydrocarbons of petroleum type pollutants during ex situ bioremediation of soil on the pilot heap (halde), during a period of 6 months, within the grounds of Petroleum ...
