Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, Amsterdam, 1999)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C6H4-X, X having a wide range of substituent effects, have been determined in CDCl3 solution. Exceptionally good ...
Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Journal of Advanced Materials, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Thermal shock behavior of alumina based refractories
(Techna Srl, Faenza, 2002)
Temperature difference and fracture resistance parameters have been used to predict the thermal shock behavior. Alumina based commercial refractories with different content of Al2O3 from 28% to 78% were used. Thermal and ...
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 ...
Modeling and investigation of SiGe based MOSFET structure transport characteristics
(8th Conference of the Yugoslav Materials Research Society, 2007)
The focus of this paper was the investigation and modeling of transport characteristics in a strained SiGe based MOSFET structure, which might be of fundamental importance for the understanding of its operating characteristics. ...
Fatigue damage detection in composite rods using fiber optic intensity based sensors
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
An application of the embedded intensity based fiber optic sensors (FOS) for fatigue damage detection in cantilevered composite rods is presented. During the fatigue test with constant amplitude of oscillations, the ...
The retention behavior of some uracil derivatives in normal and reversed-phase chromatography. Lipophilicity of the compounds
(Research Inst Medicinal Plants, Budakalasz, 2005)
The chromatographic behavior of newly synthesized uracil derivatives has been studied by normal and reversed-phase thin-layer chromatography. Benzene-methanol, benzene-acetonitrile, and benzene-isopropanol were used as ...
Release and diffusion studies of hydrogels based on itaconic acid
(8th Conference of the Yugoslav Materials Research Society, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
Composition and antimicrobial activity of essential oil of Satureja montana L. collected in Serbia and Montenegro
(Allured Publ Corp, Carol Stream, 2005)
The chemical composition of the essential oil of Satureja montana L. subsp. montana (Lamiaceae), obtained from the air-dried plant material by hydrodistillation, was analyzed using GC and GUMS. The major components were ...
Surface carriers' concentration dynamics caused by a small alternating applied voltage
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
One of our previous papers was devoted to threshold voltage in MOSFETs and MODFETs viewed as a problem of nonlinear dynamics. The behavior of surface carriers' concentration under D.C. (direct current) applied voltage has ...
