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 ...
Experimental techniques for investigating the surface oxygen formation in the N2O decomposition on Fe-MFI zeolites
(ELSEVIER SCIENCE SA, 2007)
Several experimental techniques were used to investigate the formation of surface oxygen in the N2O decomposition on an Fe-MFI zeolite. These techniques consisted of multipulse and step experiments as transient methods at ...
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 ...
