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 ...
Isolation, Purification, and Characterization of a Polygalacturonase Produced in Penicillium solitum-Decayed 'Golden Delicious' Apple Fruit
(Amer Phytopathological Soc, St Paul, 2009)
Polygalacturonase (PG) was extracted and purified from decayed 'Golden Delicious' apple fruit inoculated with Penicillium solitum. Ammonium sulfate, gel filtration, and cation exchange chromatography were used to purify ...
Structural and electrical properties of sintered zinc-titanate ceramics
(Elsevier Sci Ltd, Oxford, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO(2) were mechanically activated in a planetary ...
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 ...
Influence of different genotypes on trypsin inhibitor levels and activity in soybeans
(MDPI, BASEL, 2007)
This study describes the relationship between the two major trypsin inhibitors (TI) in soybean, i.e., the Kunitz (KTI) and Bowman-Birk (BBI) trypsin inhibitors, as well as between them and the corresponding trypsin inhibitor ...
Physical-mechanical properties of nitrodopes affected by ultra-violet radiation
(MDPI, BASEL, 2007)
The FTIR spectroscopy has been employed in this research work to monitor the process of nitrodope photodegradation, by measuring surfaces of bands typical of a nitro group. Nitric esters are subject to degradation, which ...
