Microwave-assisted and conventional synthesis of new phthalocyanines containing 4-(p-fluorophenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one moieties
(Elsevier, 2007)
New metal-free and metal (Zn, Ni, Cu and Co) phthalocyanines containing 4-(p-fluorophenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one moiety have been prepared from 1-(3,4-dicyanophenyl)-4-(p-fluorophenyl)-3-methyl-4,5- ...
Physiological changes in them in post-stress emerging Ctenanthe setosa plants under drought conditions
(Maik Nauka-Interperiodica Publishing, 2008)
The capability of Ctenanthe setosa (Rosc.) Eichler (Marantaceae), pre-exposed to severe drought stress, of adaptation to a new drought conditions was investigated. C. setosa unstressed plants were exposed to drought period ...
Molecular epidemiology of clinical Pseudomonas aeruginosa isolates carrying IMP-1 metallo-β-lactamase gene in a university hospital in Turkey
(2007)
Pseudomonas aeruginosa isolates carrying IMP- or VIM-type metallo-?-lactamase (MBL) have been increasingly reported in hospitals worldwide. One hundred P. aeruginosa clinical isolates from unrelated inpatients hospitalized ...
Macroelement (N, P, K) contents of Romulea columnae Seb. and Mauri Subsp. columnae during vegetative and generative growth phases
(Academic Journals Inc., 2007)
Romulea columnae Seb. and Mauri subsp. columnae is a geophytic plant belonging to Iridaceae. In this study nitrogen (N), phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth ...
The viscous flux-flow effect on the pinning induced magnetostriction of type-II superconductors
(2007)
We have investigated the magnetostriction of type II superconductors under the viscous flux-flow. The critical state approach was employed to obtain the magnetostriction loops versus applied field. The flux profile equations ...
Characterization and pillaring of a Turkish bentonite (Resadiye)
(Elsevier, 2007)
The shifts of the Si{single bond}O{single bond}Si stretching and the Si{single bond}O{single bond}Al and Si{single bond}O{single bond}Si bending modes, as well as the free silica peak in the IR spectra and the strengthening ...
K-shell X-ray fluorescence cross-sections and intensity ratios for some pure metals at 59.5 and 123.6 keV
(Elsevier, 2007)
K-shell X-ray fluorescence cross-sections for some pure metals such as Cr, Fe, Co, Cu, Zn, Ga, Se, Y, Mo, Cd, In, Sn, Te, Ba, Ta, W and Bi have been theoretically and experimentally determined. The Cr, Fe, Co, Cu, Zn, Ga, ...
Structural characteristics of organo-modified bentonites of different origin
(Springer, 2007)
Organobentonites were synthesized by treating Na-bentonites (Wyoming and Reşadiye) with cetylpyridinium chloride (CPC) using ion exchange method. The difference in the basal spacing by 0.65 Å and a higher mass loss by ...
Dependency of c-lattice parameter, activation energy and its magnetic power constant on x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconductors
(Elsevier, 2008)
To investigate the effect of x on c-lattice parameter, the activation energy, and the magnetic power constant of activation energy, the nominal composition of Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, ...
Determination of the protonation constants of some 4-(substituted benzylamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones by the potentiometric method in ethanol-water mixtures
(2007)
To gain more information about the effect of solvent on 4,5-dihydro-1H-1,2,4-triazol-5-ones, the stoichiometric protonation constants of thirteen triazoles in ethanol-water mixtures were determined at an ionic strength of ...
