In this article, we introduce a new way of generating copulas with the directional dependence property based on the logistic regression. The studied class of copulas leads to nonsymmetrical copula structures, therefore allowing for the development of various directional dependence…

In this study, chlorpyrifos, catechin, quercetin and catechin- or quercetin+chlorpyrifos were given to Wistar rats for 4 weeks. Chlorpyrifos increased the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT); decreased glutathione peroxidase (GPx) and glutathione–S-transferase (GST) activities in…

 In this study, the ultrastructure and histology of digestive tract of Sphex flavipennis was examined by light and electron microscopy. The digestive tract divided into foregut, midgut and hindgut. There are longitudinal and circular muscle in the haemocoel side and…

The synthesis, spectroscopic and biological activity studies of Ni(II), Cu(II) and Co(II) complexes of Schiff base ligands derived from 5-aminouracil, 2-hydroxy-1-naphtaldehyde, 2,4-dihydroxybenzaldehyde and salicylaldehyde are reported. In all cases, the complexes appear to be monomeric. The ligands coordinate in bidentate…

In this study, it is aimed to calculate the target size from its infrared (IR) image. Target is decomposed from background and target size is calculated depending on its pixel number on the thermal image. By using horizontal and vertical…

Multicast routing in wireless networking is the newest technology that works with network groups. Multicast routing plays an important role in point-to-point or multipoint-to-multipoint communications. Multicast routing gives wireless networks more efficient, reliable and secure than unicast routing, because the…

This study dealt with analyzing of naturally occurring 40K radioisotope in beach sand and seawater samples of Sarımsaklı beach at Aegean coastal region of Turkey and its contribution to natural radioactivity. By using gamma spectroscopy the mean radioactivity concentration was…

In this study, polyurethane-carbon fiber composites were prepared with excellent interface with perfect adhesion of carbon fibers with the polyurethane matrix. The polyurethane was thermoplastic polyurethane and the carbon fiber was polyacrylonitrile based with 7 micron meter thickness. The composites…

The corrosion and inhibition behaviors of low alloy Cr steel in sulfuric acid in the presence of propargyl alcohol (PA) and potassium iodide (KI) have been studied using Electrochemical Impedance Spectroscopy (EIS) and Tafel polarization method. It was found that…

A study of intermetallic compound formation at the interface between copper thin film and silicon substrate is presented in this work. Two systems; Cu/Si and Cu-(5at%) Nb/Si, were studied. From the intermetallics formed at the interfaces of two systems; as…
