Generalized point interaction and tunneling times
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
The scattering properties of four-parameter one-dimensional point interactions also define time aspect of these interactions. In this paper we investigate how different families of point interactions affect the relevant ...
Bound states in continuum generated by point interaction and supersymmetric quantum mechanics
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
Four-parameter family of point interactions represent all possible self-adjoint extensions of kinetic energy operator. We demonstrate a method for generating a bound state in the continuum of point interactions which relies ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Micro-environmentally restricted hybridoma cell growth within polysaccharide hydrogel microbeads
(IOS Press, Amsterdam, 2013)
The mechanism of micro-environmentally restricted hybridoma cell growth caused by action of local mechanical compression stress generated within various polysaccharide hydrogel matrixes is estimated by comparing the growth ...
Examination of the Microstructure and Properties of Low-Frequency Electromagnetic Casting 6060 Aluminum Alloy Billets and Bars
(Carl Hanser Verlag, Munich, 2012)
This study investigated the advantages of using low-frequency electromagnetic casting (LFEC) process compared to conventional direct chill DC casting of aluminum alloy and considered possible energy savings. The obtained ...
Modeling of metallurgical properties of sinter mixtures of non-standard raw iron-bearing materials
(Editura Stiintifica Fmr, Bucharest, 2013)
Present paper represents a methodology for establishing a relationship between the composition of mixtures of iron-bearing non-standard dispersed raw materials for production of sinter and its most important metallurgical ...
Catalysis of Hydrogen Evolution on Au(111) Modified by Spontaneously Deposited Pd Nanoislands
(Springer, New York, 2012)
Hydrogen evolution reaction was studied on Au(111) modified by palladium spontaneously deposited on the Au(111) surface from (1 mM PdSO4 center dot 2 H2O + 0.5 M H2SO4) solution at a submonolayer coverage. Number and size ...
Solvent and Structural Effects on the UV-Vis Absorption Spectra of Some 4,6-Disubstituted-3-Cyano-2-Pyridones
(Springer/Plenum Publishers, New York, 2012)
A series of 4,6-disubstituted-3-cyano-2-pyridones was synthesized and their UV-Vis absorption spectra were recorded in the region 200-600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability ...
Improved structural model of Pb-doped gamma-Bi2O3: (Bi23.68Pb0.32)(Bi1.28Pb0.72)O-38.48
(J C P D S-Int Centre Diffraction Data, Newtown Sq, 2012)
A polycrystalline single-phase sample with nominal composition Bi24PbO37 was synthesized from Bi2O3 and PbO by a high-temperature solid state reaction at 690 degrees C for 1.5 h. The compound adopts Bi12SiO20-type structure ...
Comparative analysis of influence of gamma radiation on programmable memory characteristics
(Taylor & Francis Ltd, Abingdon, 2012)
The aim of this paper is to examine the reliability of erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components subjected to the influence of gamma radiation. ...
