Composition and stability of soil aggregates in Fluvisols under forest, meadows, and 100 years of conventional tillage
(Wiley-V C H Verlag Gmbh, Weinheim, 2010)
Conversion of meadow and forest ecosystems to agricultural land generally leads to changes in soil structure. This comparative study presents the composition and stability of structural aggregates in humus horizons (0-30 ...
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 ...
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 ...
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 ...
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 ...
Response of grapevine phenology to recent temperature change and variability in the wine-producing area of Sremski Karlovci, Serbia
(Cambridge Univ Press, New York, 2016)
The historical temperature (1981-2007) and phenological (1986-2011) data were analysed for the region of Sremski Karlovci, one of the oldest grapevine growing areas in Europe, with the aim of detecting trends of changes ...
Resistance to common organophosphate and carbamate insecticides in Aphis pomi (Hemiptera: Aphididae)
(Edp Sciences S A, Les Ulis Cedex A, 2015)
Introduction. Aphis pomi (De Geer) has developed resistance to organophosphate and carbamate insecticides, as a result of long-term application of these insecticides in conventional apple orchards. For many years, the only ...
Bimetallic alginate nanocomposites: New antimicrobial biomaterials for biomedical application
(Elsevier Science Bv, Amsterdam, 2018)
Two bimetallic (Zn/Cu) alginate based nanocomposites, impregnated with carbonate or phosphate mineral phase, were prepared by a facile procedure. Mineralized samples exhibited different morphologies and properties when ...
Poly(urethane-dimethylsiloxane) copolymers displaying a range of soft segment contents, noncytotoxic chemistry, and nonadherent properties toward endothelial cells
(Wiley-Blackwell, Hoboken, 2015)
Polyurethane copolymers based on ,-dihydroxypropyl poly(dimethylsiloxane) (PDMS) with a range of soft segment contents were prepared by two-stage polymerization, and their microstructures, thermal, thermomechanical, and ...
Structural changes of Ca-alginate beads caused by immobilized yeast cell growth
(Elsevier Science Bv, Amsterdam, 2015)
Structural changes of Ca-alginate bead due to yeast cell loading and the impact on their mechanical properties were studied based on experimental data of cell number density per beads, cell rearrangement within the bead ...
