Syntheses and characterization of maleic anhydride-styrene-allyl propionate terpolymer ester derivatives
(JOHN WILEY & SONS INC, 2003)
In this study, maleic anhydride (MA)-styrene (St)-allyl propionate (AP) was produced with MA, St, and AP. It was then reacted with n-propyl alcohol (Pr), n-butyl alcohol (Bu), n-pentyl alcohol (Pn), and benzyl alcohol (Bz) ...
High-concentration tramadol-induced vasodilation in rabbit aorta is mediated by both endothelium-dependent and -independent mechanisms
(SHANGHAI INST MATERIA MEDICA, 2003)
Aim: The mechanism of tramadol-induced vasodilation was investigated using isolated rabbit thoracic aortic rings. Methods: Aortic rings from 8 rabbits were placed in organ bath and precontracted with phenylephrine (10(-5) ...
Thermal conductivity of rocks and its variation with uniaxial and triaxial stress
(PERGAMON-ELSEVIER SCIENCE LTD, 2004)
One of the prime tasks of a mining engineer is to calculate the mine cooling load necessary for mine air conditioning system, which must provide suitable working conditions for the work force primarily at the working faces. ...
Anticardiolipin antibody positivity in diabetic patients with and without diabetic foot
(ELSEVIER SCIENCE INC, 2002)
Anticardiolipin (aCL) antibodies may play a role in the enhancement of platelet aggregation and/or progression of the macrovascular diabetic complications. Also, aCL antibodies may cause or promote ischemia and thrombosis. ...
Binding energies of donor impurities in modulation-doped GaAs/AlxGa1-xAs double quantum wells under an electric field
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
In this study, we have investigated theoretically the binding energies of shallow donor impurities in modulation-doped GaAs/Al0.33Ga0.67 As double quantum wells (DQWs) under an electric field which is applied along the ...
The variation of electronic properties with the doping concentration of modulation-doped AlxGa1-xAs-GaAs double quantum wells
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007)
In this paper we have calculated the sub-band structure and the confinement potential of modulation-doped Ga1-xAlxAs-GaAs double quantum wells as a function of the doping concentration. The electronic properties of this ...
Treatment of metal containing wastewaters by natural zeolites
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2004)
In this study, removal of heavy metals in synthetic and wastewaters was studied by using natural zeolite, clinoptilolite. The activated and non-activated zeolites used were crushed and grinded to sizes between 1.0-2.0 mm. ...
The efficacy of ultrasonography in hemodynamically stable children with blunt abdominal trauma: a prospective comparison with computed
(ELSEVIER SCI IRELAND LTD, 2004)
Purpose: In this prospective study we aimed to investigate the diagnostic value of ultrasonography (US) in hemodynamically stable children after blunt abdominal trauma (BAT) using computed tomography (CT) as the gold ...
Variation of critical surface tension for wetting of minerals with roughness determined by Surtronic 3(+) instrument
(ELSEVIER SCIENCE BV, 2004)
This paper presents a correlation found between the surface roughness and critical surface tension of wetting of calcite and barite minerals. The minerals were ground in ball, rod and autogenous mills to collect samples ...
Factors affecting the oil agglomeration of sivas-divrigi Ulucayir lignite
(TAYLOR & FRANCIS INC, 2007)
In the coal industry, the coal particles need to be decreased to a very fine size because of the need of removing inorganic materials from coal. Oil agglomeration is a kind of coal cleaning technique that is used for ...
