Time and temperature dependent microbiological and mycotoxin (ochratoxin-A) levels in boza
(Elsevier Science BV, 2009)
This study describes the examination of microbiological tests and the determination of OTA in boza temperature and time dependently. Prior to the analysis, physicochemical properties of the boza samples such as moisture, ...
Dual quaternionic reformulation of electromagnetism
(Slovak Acad Sciences Inst Physics, 2003)
It can be said that Maxwell's equations are one of the well-known equations of Physics. Despite the fact that this equations are more than hundred years old (1865), they still are the cornerstone of electrodynamics. Although ...
H-1 C-13 NMR and (n)J(CH) coupling constants investigation of 4-Phenylpyridine: A combined experimental and theoretical study
(Elsevier Science BV, 2007)
Proton coupled and uncoupled C-13, H-1, DEPT, COSY and HETCOR NMR spectra of 4-Phenylpyridine (4-Phpy) have been reported for the first time except for its H-1 NMR spectrum. In order to provide a precise structural elucidation ...
Influence of heat treatment on the nanocrystalline structure of ZnO film deposited on p-Si
(Elsevier Science Sa, 2009)
The influence of heat treatment on the crystal structure, grain growth kinetics, orientation, and refractive index properties of the ZnO film deposited onto p-type single-crystalline Si substrate by sol-gel method has been ...
Thermal behavior and water adsorption of natural and modified sepiolite having dolomite from Turkey
(Springer, 2008)
The water adsorption properties of sepiolite having dolomite supplied from Eskisehir region and their exchanged forms (K+, Na+, Mg2+ and Ca2+) were investigated. The sepiolite samples were characterized using XRD, TG-DTA, ...
Structural stabilities of N-permethylated tetracations of meso-tetrakis(4-pyridyl)porphyrin, meso-tetrakis[4-(dimethylamino)phenyl]porphyrin, and their manganese(III) complexes toward hydrogen peroxide, tert-butylhydroperoxide, and sodium hypochlorite
(Soc Porphyrins & Phthalocyanines, 2004)
The degradation rate constants of the tetracations 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)porphyrin and 5,10,15,20-tetrakis(N,N,N-trimethylanilinium-4-yl)porphyrin as well as their manganese(III) complexes toward the ...
An investigation of the influence of the pairing correlations on the properties of the isobar analog resonances in A=208 nuclei
(Indian Academy Sciences, 2004)
Within the quasi-particle random phase approximation (QRPA), the method of the self-consistent determination of the isovector effective interaction which restores a broken isotopic symmetry for the nuclear part of the ...
Adsorption potential of lead(II) ions from aqueous solutions onto Capsicum annuum seeds
(Taylor & Francis Inc, 2007)
The purpose of this work was to evaluate the adsorption potential of Capsicum annumn seeds, in a batch system for the removal of lead(H) ions from aqueous solutions. The experimental results showed that this agricultural ...
Electrochemical polymerization of fluoro- and chloro-substituted anilines and copolymers with aniline
(John Wiley & Sons Inc, 2004)
Poly(2-fluroaniline) and poly(2-chloroaniline) were synthesized by an electrochemical method in an acetonitrile solution containing tetrabutylammonium perchlorate and perchloric acid. Also, the electrochemical copolymerization ...
Adsorption of Acid Blue 193 from aqueous solutions onto Na-bentonite and DTMA-bentonite
(Academic Press Inc Elsevier Science, 2004)
Dodecyltrimethylammonium bromide-modified bentonite (DTMA-bentonite) was prepared and tested as an adsorbent for an acid dye (Acid Blue 193, AB 193) removal from aqueous solution in comparison with Na-bentonite. The effect ...
