Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Processing of composite rod with embedded optical fiber

Stress Degradation Studies on Zolpidem Tartrate Using LC-DAD and LC-MS Methods
(Akademiai Kiado Zrt, Budapest, 2014)
The present study was designed to characterize the possible degradation products of zolpidem tartrate under various stress conditions according to International Conference on Harmonization (ICH) guidelines Q1A(R2). After ...
In silico approach in the assessment of chromatographic parameters as descriptors of diphenylacetamides' biological/pharmacological profile
(Taylor & Francis Inc, Philadelphia, 2020)
The selected diphenylacetamide derivatives were subjected to chromatographic and in silico approach in order to obtain significant information about their structure-activity relationships. As an early step in the assessment ...
A LFER Kinetic Study of The Reaction of 5-Substituted Orotic Acids with Diazodiphenylmethane
(Wiley, Hoboken, 2016)
Linear free energy relationships (LFER) were applied to the kinetic data for the reaction of 5-substituted orotic acids, series 1, with diazodiphenylmethane (DDM) in N,N-dimethylformamide and compared with results obtained ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Some observations on the shear fracture mode in AlMg6.5 alloy sheet
(Frankfurt : Werkstoff-Informationsgesellschaft mbH, 2001)
AlMg6.5 alloy sheet samples with different width to thickness ratio (w/t=2.5-8.3) were tested in uniaxial tension test. SEM observations revealed transgranular ductile dimple type of failure occured by shear process. It ...
Investigation of antimicrobial activity of encapsulated essential oils
(8th Conference of the Yugoslav Materials Research Society, 2007)
Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused ...
