Barrier thickness dependence of optical absorption of excitons in GaAs coupled quantum wire
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004)
We have calculated the binding energy of excitons, and the interband optical absorption in rectangular coupled quantum-well wires of GaAs surrounded by Ga1-chiAlchiAs in effective-mass approximation, using the variational ...

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 ...
