Origin of oils in the Velebit oil-gas field, SE Pannonian Basin, Serbia - Source rocks characterization based on biological marker distributions
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Twenty five crude oil samples from Velebit oil-gas field (SE Pannonian Basin, Serbia) were investigated in order to define the depositional environment, lithology, thermal maturity and depth of burial of the corresponding ...
Structural modification of fullerene thin films by highly charged iron ions
(Springer, 2007)
In this paper, the results of structural modification of fullerene thin films bombarded by highly charged iron ions (Fe6+) are presented. The properties of as-deposited and irradiated fullerene thin films have been ...
Reaction of silyl ketene acetals with epoxides: a new method for the synthesis of gamma-butanolides
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords butanolides in moderate/good yields. With epihalohydrins the reaction is regioselective and occurs at the ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
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 ...
The Effect of Some parameters of Electrolysis on Apparent Density of Electrolytic Copper Powder in Galvanostatic Deposition
(Switzerland : Trans Tech Publications Ltd, 2000)
The investigation on some properties of electrochemically deposited copper powders from copper sulphate - sulfuric acid has been performed. Relations between conditions of electrolysis of powder storage, apparent density ...
Morphology and growth of electrodeposited silver powder particles
(Elsevier, 2007)
The effect of overpotential pulsing and periodic current reversal on the morphology of silver powders was investigated using a scanning electron microscope (SEM). It is shown that the profile of pulses or current reversal ...
Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
Dexamethasone treatment affects nuclear glucocorticoid receptor and glucocorticoid response element binding activity in liver of rats (Rattus norvegicus) during aging
(Elsevier, 2007)
Aging is associated with marked changes in the biochemical processes of many organs. Basal and glucocorticoid induced of liver nuclear glucocorticoid receptor (GR) on the level of protein expression and DNA-binding activity ...
Parallel alignment of water and aryl rings-crystallographic and theoretical evidence for the interaction
(Royal Soc Chemistry, Cambridge, 2008)
Analysis of crystal structures from the Cambridge Structural Database (CSD) that involve close contact between water and aryl rings revealed the existance of conformations where the water molecule or one of its O-H bonds ...
