Fast Fourier Transform IR Characterization of Epoxy GY Systems Crosslinked with Aliphatic and Cycloaliphatic EH Polyamine Adducts
(MDPI, BASEL, 2010)
The use of fast FT-IR spectroscopy as a sensitive method to estimate a change of the crosslinking kinetics of epoxy resin with polyamine adducts is described in this study. A new epoxy formulation based on the use of ...
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 ...
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 ...
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 ...
The Effects of Aphid Traits on Parasitoid Host Use and Specialist Advantage
(Public Library Science, San Francisco, 2016)
Specialization is a central concept in ecology and one of the fundamental properties of parasitoids. Highly specialized parasitoids tend to be more efficient in host-use compared to generalized parasitoids, presumably owing ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
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 ...
Clarification of red raspberry juice using microfiltration with gas backwashing: A viable strategy to maximize permeate flux and minimize a loss of anthocyanins
(Elsevier, Amsterdam, 2013)
Red raspberry (Rubus idaeus) juice was produced by maceration of raspberry pulp at 50 degrees C for 2 h using 400 mg kg(-1) Klerzyme (R) 150 enzymatic pectolitic preparation followed by raw juice clarification with gelatin ...
Proteinase PrtP impairs lactococcin LcnB activity in Lactococcus lactis BGMN1-501: new insights into bacteriocin regulation
(Frontiers Media Sa, Lausanne, 2015)
Proteinases and bacteriocins are of great importance to the dairy industry, but their interactions have not been studied so far. Lactococcus lactis subsp. lactis BGMN1-5 is a natural isolate from homemade semi-hard cheese ...
The impact of multiple stressors on the biomarkers response in gills and liver of freshwater breams during different seasons
(Elsevier Science Bv, Amsterdam, 2017)
Biomarkers attract increasing attention in environmental studies, as a tool for detection of exposure and effects of pollution, from both natural and anthropogenic sources. This study aims to assess the impact of multiple ...
