Ecobiological study of medicinal plants in some regions of Serbia
(Czech Academy Agricultural Sciences, Prague, 2006)
Ecobiological study of medicinal plants includes the analysis of particular soil features and the ecological indexes of plant species as site indicators. Two experimental serpentine areas in northwest and central Serbia ...
Surface characteristics and modification of different carbon materials
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken ...
The morphology of cavitation damage of heat-treated medium carbon steel / Morfologija kavitacionog oštećenja srednje-ugljeničnog čelika u poboljšanom stanju
(Serbian Chemical Society, Belgrade, 2006)
In this paper the morphology of the cavitation damage to heat-treated medium carbon steel was analyzed. The experiments were conducted using a modified vibratory cavitation test set up. The erosion rates were measured by ...
An investigation into the influence of hydrogel composition on swelling behavior and drug release from poly(acrylamide-co-itaconic acid) hydrogels in various media
(Taylor & Francis Ltd, Abingdon, 2006)
The hydrogels prepared by free radical copolymerization of acrylamide and itaconic acid were investigated with regard to their composition and crosslinking degree to find materials with satisfactory swelling and drug release ...
Investigations of the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents: Part II: Pyridine mono-carboxylic acid N-oxides / Ispitivanje reaktivnosti piridin-N-oksid-monokarbonskih kiselina u reakciji sa diazodifenilmetanom u protičnim i aprotičnim rastvaračima - drugi deo
(Serbian Chemical Society, Belgrade, 2006)
The rate constants for the reaction of three isomeric pyridine mono-carbocylic acid N-oxides with diazodiphenylmethane were determined at 30 ºC in thirty two protic and aprotic solvents by the well known UV spectrophotometric ...
Nanoindentation of in situ polymers in hydroxyapatite/poly-L-lactide biocomposites
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In order to obtain more accurate properties after compaction of hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite, high-resolution measurement of mechanical properties method is proposed to determine the properties of ...
Assessment of gamma dose rates from terrestrial exposure in Serbia and Montenegro
(Oxford Univ Press, Oxford, 2006)
The gamma dose rates due to naturally occuring terrestrial radionuclides (Ra-226, Th-232 and K-40) were calculated based on their activities in soil samples, determined by gamma-ray spectrometry. A total of 140 soil samples ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, Belgrade, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
Thermal stability of an alumina-based refractory
(American Ceramic Society Bulletin, 2006)
The thermal stability, dynamic Young's modulus of elasticity, anisotropy and damage level of a 42% alumina refractory material were investigated using a water-quench test. Thermal quenching of refractories leads to crack ...
Studies on the specificity of Candida rugosa lipase catalyzed esterification reactions in organic media / Ispitivanje specifičnosti lipaze iz Candida rugosa u reakciji esterifikacije u organskom rastvaraču
(Serbian Chemical Society, Belgrade, 2006)
In this study, the feasibility of the synthesis of various flavor esters catalyzed by a commercial lipase from Candida rugosa was investigated and the process parameters were optimized. Lipase from C. rugosa successfully ...
