Purification and properties of trypsin-like enzyme from the midgut of morimus funereus (coleoptera, cerambycidae) larvae
(Wiley-Blackwell, Hoboken, 2010)
Trypsin-like enzyme (TLE) from the anterior midgut of Morimus funereus larvae was purified by anion exchange chromatography and gel filtration chromatography and characterized. Specific TLE activity was increased 322-fold ...
Co-aluminosilicate based electrodes
(Elsevier, 2010)
The influence of aluminosilicate support on the catalyst efficiency was investigated. Three different aluminosilicate materials containing cobalt (II) ion as active specie for phenol or nitrite oxidation were obtained. The ...
Liver, gills, and skin histopathology and heavy metal content of the danube sterlet (acipenser ruthenus linnaeus, 1758)
(Setac Press, Pensacola, 2010)
The sterlet (Acipenser ruthenus L.) is a bottom-feeding fish species with a direct exposure to contaminants from water and sediments. Although heavy metal pollution is believed to be one of the main threats to the sterlet ...
Study of flow and pressure field in microchannels with various cross-section areas
(Elsevier, 2010)
In this work a micro-flow sensor integrated in the bottom surface of a rectangular microchannel is used in order to evaluate simultaneously both the flow velocity and the pressure in various micro-flow conditions. In this ...
Wall effects on the velocities of a single sphere settling in a stagnant and counter-current fluid and rising in a co-current fluid
(Elsevier Science Sa, Lausanne, 2010)
Experimental results were obtained on the steady settling of spheres in quiescent media in a range of cylindrical tubes to ascertain the wall effects over a relatively wide range of Reynolds number values. For practical ...
Diffusion of drugs from hydrogels and liposomes as drug carriers
(John Wiley & Sons Ltd, Chichester, 2010)
BACKGROUND: The mass transfer of model drugs Lidocaine hydrochloride and Dihydroquercetin from hydrogels (the usual carriers for topical drugs), and hydrogels containing liposomes, as novel drug vehicles, was studied. ...
Synthesis of submicron carbon spheres by the ultrasonic spray pyrolysis method
(Elsevier, 2010)
Submicron carbon spherical particles were obtained by polycondensation of resorcinol and formaldehyde in a solution and subsequent ultrasonic spray pyrolysis of the prepared sol. Microscopic characterization indicates the ...
Voltammetric and differential pulse determination of roxithromycin
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
The oxidative behavior of antibiotic roxithromycin standard was studied at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry and differential pulse voltammetry. It was found that the value of the ...
Pyrolysis and Catalyzed Pyrolysis in the Investigation of a Neogene Shale Potential from Valjevo-Mionica Basin, Serbia
(American Chemical Society (ACS), 2010)
The generative potential of a Neogene shale from Valjevo-Mionica Basin (Serbia) was investigated using conventional pyrolysis and pyrolysis in the presence of Pt(IV)- and Ru(III)-ions at temperatures 250 and 400 degrees ...
The influence of different components on interpenetrating polymer network's (IPN's) characteristics as automotive top coats
(Elsevier Science Sa, Lausanne, 2010)
The aim of this study was to investigate the influence of different components of interpenetrating polymer networks (IPNs) on their behavior in dual curing automotive applications. Dual curing is one of possible ways to ...
