Synthesis of some new 1,2,4-triazoles starting from isonicotinic acid hydrazide and evaluation of their antimicrobial activities
(Elsevier, 2009)
5-Pyridin-4-yl-1,3,4-oxadiazole-2-thiol (2) was obtained from the reaction of isonicotinic acid hydrazide with carbon disulfide in basic media and converted into 4-amino-5-pyridin-4-yl-4H-1,2,4-triazole-3-thiol (5) by the ...
Determination of levitation force and pinning properties of (Sm123) 1-x(Yb211) x bulk superconductor depending on Yb211 doping ratio
(Wiley, 2009)
The vertical force density curves of (Sm123) 1-x(Yb211)x high temperature superconductor (HTS) samples prepared by a meltpowder-melt-growth technique were measured during vertical and lateral traverses in zero field cooling ...
The microwave-assisted synthesis and characterization of novel, octakis(2-hydroxyethoxy)resorcinarene bridged polymeric metallophthalocyanines
(Elsevier, 2009)
The new metallophthalocyanine (Zn, Cu, Ni, Co) polymers containing 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)-2,8,14,20-tetramethylresorcinarene are described. Firstly, 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)- ...
The effect of pingers on harbour porpoise, Phocoena phocoena bycatch and fishing effort in the turbot gill net fishery in the Turkish Black Sea coast
(2009)
This is the preliminary and the first study for understanding the effect of acoustic deterrent devices (pingers) on catch rates of fish (target turbot fish, Schophthalmus maeoticus and non target thornback ray, Raja clavata) ...
The polarization of X-rays and magnetic photoionization cross-sections for L3 sub-shell
(Elsevier, 2009)
The alignment of atoms with inner-shell vacancies resulting from ionization by photons was investigated by measuring the anisotropic emission of L shell X-ray lines. The X-ray line intensities were measured using an Si(Li) ...
Synthesis of methyl (E)-2′,4″-thiazachalcones and their N-alkyl derivatives, photochemistry with theoretical calculations and antimicrobial activities
(TUBİTAK, 2009)
A series of 9 new (E) -thiazachalcones (1-3), and their N -alkyl substituted derivatives (4-6), and stereoselective dimerization products (7-9) were synthesized, then tested for antimicrobial activity against all test ...

(2009)
Amaç: Araknoidit gelişiminde çeşitli nedenler suçlanmaktadır, subaraknoid kanama (SAK) da bu süreçte önemli bir öğe olabilir. Bu deneysel çalışmada (tavşan SAK modelinde) SAK'ın histopatolojik bulgular üzerine etkisini, ...
Grading of epidural fibrosis in a new rabbit experimental model for epidural adhesive scar tissue formation
(2009)
This experimental study was planned to evaluate the success of rabbit hemilaminotomy procedure and proposing of a new grading system in the evaluation of epidural fibrosis. Fourteen New Zealand white rabbits were used in ...
