On the Differential Geometry of GLq(1∣1)GL_q(1| 1)

The differential calculus on the quantum supergroup GL$_q(1| 1)$ was introduced by Schmidke {\it et al}. (1990 {\it Z. Phys. C} {\bf 48} 249). We construct a differential calculus on the quantum supergroup GL$_q(1| 1)$ in a different way and we obtain its quantum superalgebra. The main structures are derived without an R-matrix. It is seen that the found results can be written with help of a matrix $\hat{R}$Comment: 14 page

The status of deconfinement in SU(3) gauge theory

Çelik T, Engels J, Satz H. The status of deconfinement in SU(3) gauge theory. Zeitschrift für Physik, C: Particles and Fields. 1984;22(3):301-306.We assess the reliability of present lattice calculations in SU(3) Yang-Mills theory at finite physical temperature. There are clear deviations from asymptotic scaling, but the ratios of deconfinement temperature, latent heat and string tension are found to remain constant under lattice changes

Effective conformational search methods for biological macromolecules

The configuration space of many complex physical systems presents a rough energy landscape consisting of tremendous number of local minima separated by high energy barriers. One way to overcome these barriers is to perform the simulation in a generalized-ensemble where each state is weighted by a non-Boltzmann probability weight factor. Multicanonical Ensemble Approach overcomes this difficulty by performing a random walk in one-dimensional energy space. Our attempts to design hybrid generalized ensemble algorithms will be reported. The folding of a protein into its native structure involves one or more transitions between distinct phases. The representation of the energy landscape would be useful for the determination of the conformational transition temperatures. Such a study would lead to clear indications of the equilibrium conformations of proteins and provide a detailed picture of the folding pathway. The topographic structure of energy landscape of short peptides will be presented

Antifungal and antibacterial effects of some acrocarpic mosses

In this study, the antifungal and antibacterial effect of 6 different  acrocarpous mosses were tested in vitro aganist 8 different  microorganisms. For the extraction, ethyl alcohol, methyl alcohol, acetone and chloroform were used as solvents. While the highest antimicrobial effect was seen in methyl alcohol extracts, extracts of chloroform showed the lowest level of antimicrobial effect. Grimmia anodon Bruch & Schimp. which is one of the acrocarp mosses used in this study, showed the highest activity in termsof the number of microorganism affected. Tortella tortuosa (Hedw.) Limpr. only has effect on Candida albicans ATCC 16231 strain. All the results were compared with standard antibiotic discs, ketoconazole (50 ìg), ampicillin (10 ìg), eritromycin (15 ìg) and vancomycin (30 ìg).Key words: Moss, acrocarpous, antimicrobial effect

Investigation of antimicrobial activity of some Turkish pleurocarpic mosses

In this study, the antimicrobial activities of different extracts from the five pleurocarpic mosses (Platyhypnidium riparioides (Hedw.) Dixon, Leucodon sciuroides (Hedw.) Schwägr., Hypnum cupressiforme Hedw., Homalothecium sericeum (Hedw.) Br.Eur., and Anomodon viticulosus (Hedw.) Hook & Taylor.) were tested aganist eight bacterial and fungal strains. For the extraction, four different solvents (ethyl alcohol, methyl alcohol, chloroform and acetone) were used. While methanolic extracts of P. riparioides showed the highest antibacterial effect against the Gram-negative bacterium Pseudomonas aeroginosa ATCC 27853, acetone extract of A. viticulosus showed the highest antifungal effect against the fungus Saccharomyces cerevisiae ATCC. All the results were compared with standard antibiotic discs: ketoconazole (50 μg), amphicillin (10 μg), eritromycin (15 μg), penicillin (10 μg) and vancomycin (30 μg).Key words: Moss, pleurocarpic, antimicrobial activity

The Investigation on Physical Education Teacher Candidate’s Resilience, Tenacity and Motivation Levels

The main purpose of this study is to examine possible relationships between resilience, tenacity and motivation of physical education teacher candidates. In addition, resilience, tenacity and motivation levels were examined according to class and gender levels. Participants of the study are 154 PE students in Ağrı province. There are 50 female participants and 104 male students. The Resilience Scale adapted to Turkish by Sarıçam et al. (2012). The Tenacity Scale-Short Form adapted to Turkish by Sarıçam et al. (2016) Stability Scale and Personal Information Form were used. To analyze the data, t test, ANOVA, Pearson moment product correlation analysis and multiple regression analysis were used. 99% p <.01 was taken as confidence interval in the study. According to research findings, there are statistically significant relationships in positive direction among the resilience, tenacity and motivation in the candidates of physical education teachers. When the resilience increases, tenacity and motivation levels also increase. According to gender and class level, resilience, tenacity and motivational stability do not differ statistically. The study can be expanded by adding different sections and classes

Secondary structure prediction of beta-hairpin peptide tryptophan zipper-I

We have investigated the folding properties of tryptophan zipper-I molecule which folds into a stable β-hairpin motif in aqueous solution as suggested by nuclear magnetic resonance (NMR) experiments. An all-atom presentation, including hydrogen, was used with an implicit solvent. As a simulation technique, simulated tempering algorithm was used to obtain equilibrium conformations of the molecule at ten distinct temperatures. Our minimum energy configuration obtained from simulated tempering algorithm is a β-hairpin motif with 1.30 Å backbone root-mean-square deviation from the reference PDB structure (1le0.pdb). Several quantities and exhaustive folding free energy landscapes were determined and discussed in order to clarify the folding behavior. © 2008 Elsevier Ltd. All rights reserved
