EFFECTS OF SEMEN EXTENDER SUPPLEMENTED WITH L-METHIONINE AND PACKAGING METHODS (STRAWS AND PELLETS) ON POST-THAW GOLDFISH (Carassius auratus) SPERM QUALITY AND DNA DAMAGE
(Cryo Letters, 2015)BACKGROUND: Amino acids protect spermatozoa against cell damage during cryopreservation due to have antioxidant property and found in seminal plasma at high concentration. OBJECTIVE: The aim of the present work was to ... -
A different approach to solar cell simulation
(Pergamon-Elsevier Science Ltd, 2015)Zero barrier height inhomogeneity in the device is generally assumed to conform to Gaussian distribution in the literature. In this study, zero barrier height inhomogeneity has been adopted to obey random distribution. ... -
Preparation and radiation attenuation performances of metal oxide filled polyethylene based composites for ionizing electromagnetic radiation shielding applications
(Springer, 2015)Linear low density polyethylene based and metal oxide (PbO and WO3) filled composites were prepared and characterized for ionizing electromagnetic radiation (IEMR) shielding applications. Density properties, microscopic ... -

Error analysis of the Chebyshev collocation method for linear second-order partial differential equations
(Taylor & Francis Ltd, 2015)The purpose of this study is to apply the Chebyshev collocation method to linear second-order partial differential equations (PDEs) under the most general conditions. The method is given with a priori error estimate which ... -
Determination of differences in the biochemical properties of sperm activating and non-activating ovarian fluids and their influences on sperm motility in rainbow trout (Oncorhynchus mykiss)
(Elsevier Science Bv, 2015)Ovarian fluid (OF) of individual female fish can initiate and affect sperm motility characteristics differently. Although it is naturally expected that OFs should stimulate and prolong sperm motility, some OFs inhibit sperm ... -
Fire-related germination and early seedling growth in 21 herbaceous species in Central Anatolian steppe
(Academic Press Ltd- Elsevier Science Ltd, 2015)The role of fire in shaping plant traits in crown fire ecosystems is well understood, but little attention has been given to surface fire ecosystems. We studied the effect of fire-related cues (heat shock and smoke) on the ... -
Temperature dependent symmetry to asymmetry transition in wide quantum wells
(Elsevier, 2015)Quasi-two dimensional electron systems exhibit peculiar transport effects depending on their density profiles and temperature. A usual two dimensional electron system is assumed to have a 6 like density distribution along ... -
Geographical distribution and frequencies of organophosphate-resistant Ace alleles and morphometric variations in olive fruit fly populations
(John Wiley & Sons Ltd, 2015)BACKGROUNDIn the Mediterranean basin, organophosphate (OP) insecticides have been used intensively to control olive fly populations. Acetylcholinesterase (Ace) is the molecular target of OP insecticides, and three ... -
A selective molecularly imprinted polymer for immobilization of acetylcholinesterase (AChE): an active enzyme targeted and efficient method
(Wiley-Blackwell, 2015)In the present study, we immobilized acetylcholinesterase (AChE) enzyme onto acetylcholine removed imprinted polymer and acetylcholine containing polymer. First, the polymers were produced with acetylcholine, substrate of ... -
Comparative investigations of the thermotropic and optical refractive properties in micellar isotropic phase and nematic-calamitic mesophase of hexadecyltrimethyl ammonium bromide/water and hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic liquid crystalline systems
(Springer, 2015)We report the thermotropic properties and measurements of the temperature and concentration dependences of the refractive index in isotropic micellar L (1) phase and nematic-calamitic N (C) mesophase of the hexadecyltrimethyl ... -
Comparison of fuzzy logic based models for the multi-response surface problems with replicated response measures
(Elsevier, 2015)A replicated multi-response experiment is a process that includes more than one responses with replications. One of the main objectives in these experiments is to estimate the unknown relationship between responses and ... -
Shading effect on the energy rating of two identical PV systems on a building facade
(Pergamon-Elsevier Science Ltd, 2015)The first BIPV system of Turkey was installed on the facade and two towers of the Staff's Block of Education Faculty building of Mugla Sitki Kocman University in February 2008. The PV systems cover 405 m(2) (60 tilted ... -
Biologically active flavonoids from Dodonaea viscosa and their structure-activity relationships

Fabrication of Biofuel Cell Based on Nanomaterial Modified Composite Glassy Carbon Paste Electrode
(Bentham Science Publ Ltd, 2016)In this work, an enzymatic biofuel cell (BFC) was developed by combining nanomaterial modified and plain glassy carbon paste electrodes (GCPE). Because of the composite nature of GCPE, very practical and economic bio-anode ... -
Towards the electrochemical diagnosis of cancer: nanomaterial-based immunosensors and cytosensors

Mitochondrial genetic variations of an introduced freshwater fish, goldfish Carassius auratus at the frontier between Europe and Asia (western Anatolia, Turkey): proximity to Europe rather than East Asia?
(Taylor & Francis Ltd, 2016)Carassius auratus is one of the most significant ornamental and food fishes of the world that is globally distributed and well known. Although it is known to have existed at least for six decades and expanding its distribution ... -
Microbial glucose biosensors based on glassy carbon paste electrodes modified with Gluconobacter Oxydans and graphene oxide or graphene-platinum hybrid nanoparticles
