Binding energy of excitons in symmetric and asymmetric coupled double quantum wells in a uniform magnetic field
(IOP PUBLISHING LTD, 2000)
The binding energy of excitons in symmetric and asymmetric coupled double GaAs/Ga1-xAlxAs quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic ...
Effect of periodontal treatment on IL-1 beta, IL-1ra, and IL-10 levels in gingival crevicular fluid in patients with aggressive periodontitis
(WILEY, 2008)
Aim:The aim of this study was to examine the effect of phase I periodontal treatment on the levels of interleukin (IL)-1 beta, IL-1ra, and IL-10 in gingival crevicular fluid (GCF) in patients with generalized aggressive ...
Radiation induced superabsorbent hydrogels. Acrylamide/itaconic acid copolymers
(WILEY-V C H VERLAG GMBH, 2001)
Acrylamide/itaconic acid hydrogels in the form of rods are prepared by gamma -irradiation of ternary mixtures of acrylamide/itaconic acid/water with 2.00-5.71 kGy gamma -rays. Spectroscopic and thermal characteristic the ...
Microthermometric and O- and H-isotope characteristics of the mineralizing fluid in the Akguney copper-lead-zinc deposit, NE Turkey
(TAYLOR & FRANCIS INC, 2009)
The Akguney copper-lead-zinc deposit (Ordu Province) is actively mined in the eastern Black Sea Region of Turkey. This deposit consists of ore-bearing veins emplaced along fault zones and hosted by slightly altered Upper ...
Crystal structure of cis,cis,cis-1,2-epoxy-3,5-dibromo-4-hydroxy tetralin
(WILEY-V C H VERLAG GMBH, 2003)
The title compound, C10OH8Br2O2, consists of a tetrahydronaphthalene skeleton composed of a six-membered ring A with arene oxide, monobromo and monohydroxy atoms in cis,cis,cis configuration held in a boat conformation and ...
USING FUZZY SETS FOR FILTERING TOPOGRAPHIC MAP IMAGES
(MINISTRY COMMUNICATIONS & HIGH TECHNOLOGIES REPUBLIC AZERBAIJAN, 2008)
This paper demonstrates the use of fuzzy sets for filtering contour lines in topographic map images. The fuzzy filtering is motivated by a need for effective automated analysis of data only available in the form of printed ...
Changes in spontaneous contractions of rat ileum by aflatoxin in vitro
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Aflatoxins are a group of mycotoxins produced by toxigenic strains of Aspergillus flavus, Aspergillus parasiticus and Aspergillus nomius as secondary metabolites. Most of the studies on the aflatoxins have focused mainly ...
N-methacryloyl-(L)-histidine methyl ester carrying porous magnetic beads for metal chelate adsorption of cytochrome c
(ELSEVIER SCIENCE BV, 2007)
A magnetic metal-chelate adsorbent utilizing N-methacryloyl-(L)-histidine methyl ester (MAH) as a metal-chelating ligand was prepared. MAH was synthesized using methacryloyl chloride and L-histidine methyl ester. Magnetic ...
Sleep Quality in Hemodialysis Patients
(UNIVERSITATSVERLAG ULM GMBH, 2008)
Background: The need for sleep is a part of basic human needs and their daily activities. Hemodialysis changes the quality of sleep, and poor sleep can have serious detrimental effects on health, possibly resulting in ...
Immobilization of pepsin on chitosan beads
(ELSEVIER SCI LTD, 2007)
In this study, chitosan beads were prepared by using a cross-linking agent and the resulting beads were employed in immobilization process. Studies on free and immobilized pepsin systems for determination of optimum ...
