Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
(Acta Physica Polonica A, 2009)
Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt")/Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
A case study on the effect of thermal residual stresses on the crack-driving force in linear-elastic bimaterials
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The effect of thermal residual stresses in bimaterial structure with initial crack located near a sharp interface is discussed in this paper. Bimaterial compact tension (CT) specimen is used in the analysis, and the residual ...
Fermentation of wheat and triticale hydrolysates: A comparative study
(Elsevier Sci Ltd, Oxford, 2009)
In bioethanol production four wheat varieties were investigated: NS 40S, Renesansa, Rapsodija and Dragana, as well as four triticale varieties: Oganj, Jutro, Odisej and NST 21/06. The samples were grinded and mixed with ...
Ultraviolet Protection Factor of Gray-state Plain Cotton Knitted Fabrics
(Sage Publications Ltd, London, 2009)
The protection provided by clothing against ultraviolet (UV) radiation has been the subject of considerable recent research. However, a lack of investigations concerned with the influence of yarn properties on UV protection ...
