Specimens of high-T(c) superconductors, YBCO and (YBCO)1.96 Ag0.04, were irradiated with gamma-rays up to an integrated dose of 77 MR. Electrical resistance vs temperature and the X-ray diffraction patterns of the monolayers of the sample powders were obtained before and after the irradiations. The normal state resistance of the pure and Ag-doped YBCO specimens gradually increase as the gamma-dose increases. The intensities of the X-ray diffraction peaks of the monolayers of the YBCO powders decrease with gamma-irradiation without significant change of diffraction angles or peak widths. The zero resistance transition temperature of the Ag-doped YBCO specimens decreases by about 0.5% with gamma-irradiation at 77 MR. These observations indicate that the high-T(c) superconductor YBCO is quite sensitive to gamma-irradiation but drastic lattice expansion does not occur up to a gamma-dose of 77 MR.

The mapping class group is generated by two commutators
Baykur, R. Inanc; Korkmaz, Mustafa (2021-05-01)
We show that the mapping class group of any closed connected orientable surface of genus at least five is generated by only two commutators, and if the genus is three or four, by three commutators. (C) 2021 Elsevier Inc. All rights reserved.
Investigation of the effects of folk medicinal plant Epilobium Hirsutum L. on cytochrome P450 dependent and antioxidant enzymes : a molecular approach
Karakurt, Serdar; Adalı, Orhan; Şen, Alaattin; Department of Biochemistry (2013)
The genus Epilobium sp. (Onagraceae) is widely distributed all over the world and consists of nearly 200 species. Epilobium hirsutum L. (EH) one of the members of this genus is known as its analgesic, anti-microbial and anti-proliferative activity and it is used in our country as an alternative medicine. The pharmacological effect of EH could be explained by the presence of polyphenolics including steroids, tannins and flavonoids in the aerial parts. Cytochrome P450s (CYPs) known as phase I enzymes have imp...
Studying Tunicata WBR using Botrylloides anceps
Karahan, Arzu (Springer, London/Berlin , 2021-10-01)
Tunicates are marine filter-feeding invertebrates that can be found worldwide and which are the closest phylogenetic group to the vertebrates (Craniata). Of particular interest, colonial tunicates are the only known chordates that can undergo Whole Body Regeneration (WBR) via vascular budding. In Botrylloides anceps, a fully functional adult regenerates from a fragment of the vascular system in around two weeks after amputation. In this chapter, we present protocols to collect B. anceps colonies, breed them...

Assessment of genetic diversity in picea orientalis (l.) link. in genetic resources by microsatellites
Özdilek, Aslı; Kaya, Zeki; Temel, Fatih; Department of Biology (2015)
Picea comprises about 40 species in the world. One of these species, oriental spruce (Picea orientalis (L.) Link.) is naturally distributed in northeastern Turkey, mostly in Artvin Province and in a part of Georgia close to the coast of the Black Sea region. The limited distribution of species and increased anthropogenic threats to its genetic resources signify the importance of studying genetic diversity of the species to have better conservation and management programs. Here, we report the first high thro...
