Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
(Elsevier, 2009)
In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that ...
Double-walled carbon nanotube based carbon paste electrode as xanthine biosensor
(Springer Wien, 2009)
We describe the first usage of a double walled carbon nanotube (DWCNT) modified carbon paste electrode as biosensor transducer. Xanthine was chosen as a substrate for evaluation of the electrode performance. Proper amount ...
The In Vitro Antimicrobial Activities of the Essential Oils of Some Lamiaceae Species from Turkey
(Mary Ann Liebert, Inc, 2009)
In this study, antimicrobial activities of the essential oils obtained by using the hydrodistillation method from some lamiaceous plants-Mentha longifolia (L.) Hudson ssp. longifolia, M. longifolia (L.) Hudson ssp. typhoides ...
Removal of cationic dyes by kaolinite
(Elsevier Science Bv, 2009)
The removal of cationic dyes such as maxilon yellow 4GL (MY 4GL) and maxilon red GIRL (MR GRL) on kaolinite from aqueous solutions has been studied according to the adsorption method. The adsorbed amount of dyes on kaolinite ...
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ...
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 ...
