Horizontol dissemination of tem- and SHV-type Beta-Lactamase genes carrying resistance Plasmids amongst clinical isolates of enterobacteriaceae
(Brazilian Journal of Microbiology, 2008)
Genişletilmiş spektrumlu beta-laktamaz (ESBL) üreten bakteriler, dünya çapında artan sıklıkta izole edilmiştir. ESBL'nin ifadesi genellikle çoklu ilaç direnci ve direnç plazmidleri tarafından yayılma ile ilişkilidir. 2000 ...
Effect of Transport Current on the Pinning Induced Magnetostriction of Type-II Superconductors
(Polish Acad Sciences Inst Physics, 2008)
Teorik olarak taşıma akımının ve uygulanan manyetik alanın tip-II süperiletkenlerin manyetostriksiyonu üzerindeki etkisini araştırdık. Bir süperiletken levha örneğinin manyetostriktif tepkisini incelemek için, mevcut ...
Synthesis of 4-Amino-4,5-dihydro-1H-1,2,4-triazole-5-ones and their Isatin-3-imine Derivatives
(MDPI, ST ALBAN-ANLAGE 66, 2005)
Iminoester hidroklorürler 1 sentezlenmiştir. Bu bileşikler daha sonra ester etoksikarbonil hidrazonlar 2'ye dönüştürüldü ve bunlardan sırasıyla yeni bir ikame edilmiş 4-amino-4,5-dihidro-lH-1,2,4-triazol-5-onlar, 3 serisi ...
Vacancy transfer probabilities from K to L shell for low atomic number elements at 5.96 keV
(Polish Academy of Sciences, 2010)
Vacancy transfer probabilities from K to L shell were measured using I K?/IK? intensity ratios for six elements in the atomic region 16 ? Z ? 22. The K X-rays from the targets excited by 5.96 keV (1.85 GBq 55Fe filtered ...
A review on population characteristics of Gilthead Seabream (Sparus auratd)
(Medwell Online, 2010)
S. aurata is a marine fish living along the Atlantic coasts of Europe and the Mediterranean Sea. It is an important food species, so that its production reached 128,943 t in the European aquaculture in 2008. However, little ...
Horizontol dissemination of TEM- and SHV-type beta-lactamase genes-carrying resistance plasmids amongst clinical isolates of Enterobacteriaceae
(SOC BRASILEIRA MICROBIOLOGIA, AV PROF LINEU PRESTES, 1374, 05508 SAO PAULO, BREZİLYA, 2008)
The extended-spectrum ?-lactamase (ESBL)-producing bacteria have been isolated at increasing frequency worldwide. Expression of ESBL is often associated with multidrug resistance and dissemination by resistance plasmids. ...
Synthesis, characterization and cyclization reactions of some new bisthiosemicarbazones
(Arkat, 2009)
The reaction of trans-1, 4-dichloro-2-butene 1 with selected phenols affords (E)-1, 4-bis(aryloxy)-2-butenes 2a-d which are converted into bis-thiosemicarbazones 3a-h via the reactions with thiosemicarbazide and 4-methyl ...
Chemical composition and antimicrobial activity of essential oils from Centaurea appendicigera and Centaurea helenioides
(Taylor & Francis LTD., 2009)
The chemical components and antimicrobial activity of the essential oils from Centaurea appendicigera C. Koch and Centaurea helenioides Boiss, two different endemic members of the genus Centaurea L. (Asteraceae), were ...
Improvement of superconducting properties of MgB2 by changing the argon ambient pressure and sintering conditions
(Institute of Physics Publishing, 2009)
We have investigated various characteristic properties depending on sintering conditions of MgB2 samples prepared by the standard solid state reaction method. It is inferred from experimental results that the crystallinity ...
