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 ...
The usage of optical fibers for damage detection in ballistic protection composite laminates / Upotreba optičkih vlakana za detekciju oštećenja kompozitnih laminata namenjenih za balističku zaštitu
(Association of Chemical Engineers of Serbia, 2006)
This paper describes the procedure of embedding fiber optic sensors in laminar thermoplastic composite material, as well as damage investigation after ballistic loading. Thermoplastic-reinforced composite materials were ...
Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
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 ...
Solvent and substituent effect on electronic spectra of N-(4-substitutedphenyl)-2,3-diphenylpropanamides
(Arkat Usa Inc, Gainesville, 2006)
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects ...
Thermogravimetric analysis of the total lipids extracted from the fatty tissue of fallow deer (Cervus Dama dama L) / Termogravimetrijska analiza ukupnih lipida ekstrahovanih iz masnog tkiva jelena lopatara (Cervus Dama dama L.)
(Serbian Chemical Society, Belgrade, 2006)
Thermogravimetry, TG, of lipids is an appropriate analytical method, commonly used to correlate the kinetic parameters of the thermal degradation of lipids and their composition. Thus, samples of total lipids extracted ...
Karakterizacija površine netkanog sorpcionog materijala na bazi vune kao sekundarne sirovine / Surface characterization of recycled wool-based nonwoven sorbent
(Savez inženjera i tehničara tekstilaca Srbije, Beograd, 2006)
Praćenje promena morfoloških svojstava površine vlakana nastalih modifikovanjem netkanog sorpcionog materijala na bazi vune kao sekundarne sirovine biopolimerom hitozanom i/ili niskotemperaturnom plazmom je od velike ...
The adhesion of epoxy cataphoretic coating on phosphatized hot-dip galvanized steel / Adhezija epoksidne kataforetske prevlake na fosfatiranom pocinkovanom čeliku
(Association of Chemical Engineers of Serbia, 2006)
The influence of hot-dip galvanized steel surface pretreatment on the adhesion of epoxy cataphoretic coating was investigated. Phosphate coatings were deposited on hot-dip galvanized steel and the influence of fluoride ...
Fitness-for-purpose assessment of repaired feedwater heater / Ocena podobnosti za upotrebu zagrejača napojne vode posle popravke
(Society for Structural Integrity and Life, Institute for Material Testing, 2006)
The leakage of tube-tubesheet joint of feedwater heater on the inlet required redesign and repair by additional tube welding. The original design took into account only the sealing, and subsequently after some period leakage ...
Synthesis of N-and N,N-dialkyl-S-alkylthiolcarbamates by the rearrangement of N-and N,N-dialkyl-O-thioncarbamates / Sinteza N- i N,N-dialkil-S-alkiltiol-karbamata premeštanjem N- i N,N-dialkil-O-alkiltionkarbamata
(Association of Chemical Engineers of Serbia, 2006)
A series of N- and N,N-dialkyl-S-alkylthiolcarbamates were synthesized by the rearrangement of N- and N,N-dialkyl-O-alkylthioncarbamates in the presence of diethyl sulfate. The synthesis of some compounds without catalyst ...
