Mass transfer in vertical liquid-solids flow of coarse particles
(Powder Technology, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
Study on fisetin-aluminium(III) interaction in aqueous buffered solutions by spectroscopy and molecular modeling
(Elsevier Science Inc, New York, 2009)
Spectroscopic (UV/visible and IR) and theoretical studies were used to assess relevant interaction of fisetin, a tetrahydroxylated flavone molecule, and trivalent aluminium in a wide range of buffered aqueous solutions. ...
Removal of N-terminal peptides from β-lactoglobulin by proteolytic contaminants in a commercial phenol oxidase preparation
(International Dairy Journal, 2009)
The use of enzymes may improve the functional properties of various food ingredients. The aim of this study was to examine the effects of proteolytic contaminants in phenol oxidases on β-lactoglobulin (BLG). In the presence ...
5,10:13,14-Disecosteroids: novel modified steroids containing 10- and 9-membered rings
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
In this paper a synthetic pathway to the modified 5,10:13,14-bisfragmentation cholestane derivatives 8-14 is described. The synthesis involves introduction of the 5α- and 14α-hydroxyl groups in the cholestane molecule and ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
Statistical design of experiments of acid activation of smectite clay from Serbia and its bleaching capacity
(Wiley, Hoboken, 2009)
BACKGROUND: Serbian smectite clay has been activated using a response surface method with central composite design. Because, among the criteria of an edible oil, colour is the most important factor in the commercial value ...
Allergenicity and immunogenicity of the major mugwort pollen allergen Art v 1 chemically modified by acetylation
(Wiley-Blackwell Publishing, Inc, Malden, 2009)
Treating allergies with modified allergens is an approach to make the treatment safer and more efficient. Art v 1 is the most prominent allergen of mugwort pollen and a significant cause of hayfever around Europe. The aim ...
CO2 looping cycles with CaO-based sorbent pretreated in CO2 at high temperature
(Chemical Engineering Science, 2009)
In this study, pretreatment of CaO-based sorbent in a CO2 atmosphere at high temperature is investigated for its effect on CO2 capture. Three limestones from three widely different geographical locations are used for the ...
Freshwater cyanobacterial blooms and primary liver cancer epidemiological studies in Serbia
(Journal of Environmental Science and Health - Part C Environmental Carcinogenesis and Ecotoxicology, 2009)
A large part of Central Serbia experiences continual shortage of sufficient ground water resources. For that reason, more than 20 reservoirs serve as drinking water suppliers. Significant and persistent cyanobacterial ...
SO2 Retention by CaO-based sorbent spent in CO2 looping cycles
(American Chemical Society (ACS), 2009)
CaO-based looping cycles are promising processes for CO2 capture from both syngas and flue gas. The technology is based on cyclical carbonation of CaO and regeneration of CaCO3 in a dual fluidized-bed reactor to produce a ...
