Adsorption of organic pollutants over microporous solids investigated by microcalorimetry techniques
(Springer, Dordrecht, 2010)
This work is focused on the gas and liquid-phase adsorption of pollutants: propanol, 2-butanone, phenol and nicotine onto zeolites (H-BETA, H-ZSM-5, H-MCM-22, and clinoptilolite). Textural properties and origin of zeolites ...
The Effects of the pH Value of the Swelling Medium on the Kinetics of the Swelling of a Poly(acrylic acid) Hydrogel
(John Wiley & Sons Inc, Hoboken, 2010)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in buffer solutions of different pH values (5, 7, and 9) at temperatures ranging from 30 to 40 degrees C were determined. The possibilities ...
Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100°-1400°C for 2h. The decrease in powder's ...
Effect of dicamba on wheat haploid embryo development
(Akademiai Kiado Zrt, Budapest, 2008)
An interspecies zygote derives after wheat x maize crosses. This zygote aborts in absence of auxin stimulation. Treatment with dicamba is widely used to promote wheat haploid embryo development. We analyzed the effect of ...
Vertical distribution of 137Cs in cultivated and undisturbed areas / Vertikalna rasprostranjenost cezijuma-137 u obradivim i neobradivim zemljištima
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper introduces the distribution BACKGROUND: and unique characteristics of 137Cs in cultivated and undisturbed areas. The samples were taken from three measuring points of the depth of 1 m. We examined all visible ...
Diversity and host associations of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) in the farmlands of western Iran
(Acta Entomologica Musei Nationalis Pragae, 2012)
This study presents the results of a survey of aphid parasitoids of the subfamily Aphidiinae (Hymenoptera: Braconidae) in western Iran. Thirty nine species of aphid parasitoids belonging to nine genera were collected and ...
Correlations between statistical moments of soil aggregate size distributions
(International Agrophysics, 2010)
In this paper, following the common practice, the shapes of soil particles size distributions are quantified by higher-order statistical parameters: skewness, flatness, superskewness, superflatness, hyperskewness and ...
Two new species of aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from the Balkan Peninsula
(Zootaxa, 2011)
Two new species of aphid parasitoids from the Balkan Peninsula are described. Aphidius chaetosiphonis sp. n. was reared from Chaetosiphon sp./Potentilla clusiana, while Aphidius balcanicus sp. n. was reared from Acyrthosiphon ...
The Possibility of Producing a Special Type of Beer Made from Wort with the Addition of Grape Must
(Inst Brewing, London, 2010)
J. Inst. Brew. 116(4), 440-444, 2010 The possibility of producing a beverage by wort fermentation enriched with grape must was examined. Must, from two different varieties of grapes, was added to conventional brewer's wort. ...
Effects of high hidrostatic pressure on the viscosity of beta-lactoglobulin solution
(Croatian Dairy Union, 2011)
In this research new experimental data for the pressure dependence of the viscosity of beta-lactoglobulin solution are presented. The experimental investigation is based on in-situ viscometric measurement technique which ...
