Current-direction-induced rectification effect on (integer) quantized Hall plateaus
(Edp Sciences S A, 2009)
Current distribution across narrow Hall bars in out of linear response regime is studied within a self-consistent Hartree-type mean-field approximation for samples which are equally and unequally depleted laterally. The ...
Interaction-mediated asymmetries of the quantized Hall effect
(Epl Association, European Physical Society, 2009)
Experimental and theoretical investigations on the integer quantized Hall effect in gate-defined narrow Hall bars are presented. At low electron mobility the classical (high-temperature) Hall resistance line R(H)(B) cuts ...
Electrostatic screening and experimental evidence of a topological phase transition in a bulk quantum Hall liquid
(Iop Publishing Ltd, 2009)
The electrostatic screening of a medium disordered quantum Hall liquid was investigated using an electric field penetration (EFP) technique. At sufficiently low temperatures and at magnetic fields corresponding to the ...
PHYSICAL FITNESS OF VISUALLY IMPAIRED ADOLESCENT GOALBALL PLAYERS
(Sage Publications Inc, 2009)
This study compared the physical fitness of 28 visually impaired goalball players (M = 13 yr.) and a group of 27 less active age-matched adolescents. Physical characteristics (age, height, weight, sex) and visual acuity ...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION
(Estonian Academy Publishers, 2009)
The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were ...
Surface characteristics of wood pre-impregnated with borates before varnish coating
(Forest Products Soc, 2009)
Some surface characteristics of Calabrian pine (Pinus brutia Ten) pre-impregnated with borates before varnish coating were studied. Boric acid, borax, and sodium perborate were used as borates. An alkyd-based synthetic ...
Design and construction of school work tables for developing countries
(Forest Products Soc, 2009)
Cyclic tests were conducted to determine the strength and durability of two types of school work tables designed for use in developing countries which were constructed with round mortise and tenon joints. The frames were ...
Performance Comparision of Internal and External Rotor Structured Wind Generators Mounted from Same Permanent Magnets on Same Geometry
(Kaunas Univ Technology, 2009)
In this study, internal and external rotor radial-flux machine constructions built With surface mounted by applying the same NdFeB were compared according to torque density, vigorous material weight, outer radius, total ...
Investigation of the Effects of Rotor Pole Geometry and Permanent Magnet to Line Start Permanent Magnet Synchronous Motor's Efficiency
(Kaunas Univ Technology, 2009)
The effects of rotor pole geometry to line start permanent magnet synchronous motor's efficiency are discussed. To achieve this goal, several LSPMSMs which have eight type rotors and 550 Watts power have been simulated and ...
Comparison of mechanical properties of solid wood and laminated veneer lumber fabricated from Turkish beech, Scotch pine, and Lombardy poplar
(Forest Products Soc, 2009)
Selected mechanical properties of laminated veneer lumber (LVL) prepared from Turkish beech (Fagus orientalis L.), Scotch pine (Pinus sylvestris L.), and Lombardy poplar (Populus nigra) veneers bonded with polyvinyl acetate ...
