Histology and fine structure of three anchovy outer retinae is investigated by light- and electron microscopy and computer aided topographic mapping. They all possess novel linear triple cones with two large lateral components and one small central component. Engraulis encrasicolus has a polycone-dominated retina with two triple-cone sectors, the retinae of Cetengraulis mysticetus and Anchovia ...

We present numerical solutions of a two-dimensional Riemann problem for the compressible Euler equations that describes the Mach reflection of weak shock waves. High resolution finite volume schemes are used to solve the equations formulated in self-similar variables. We use extreme local grid refinement to resolve the solution in the neighborhood of an apparent but mathematically inadmissible ...

The new conjugated organometallic polymer (-spacer-C[triple bond]C-Pt(PBu3)2-C[triple bond]C-)n (3; spacer = para-bis(diphenyl(tetramethyl)quinone diimine) and the cyclic mononuclear model complex, spacer'-C[triple bond]C-Pt(PEt3)2-C[triple bond]C x CuCl (4; spacer' = ortho-diphenyl-2,3,5,6-tetramethyl-1,4-benzoquinone diimine) were synthesized from the 1:1 condensation of the corresponding die...

            For more than 70% of women, hot flashes are a common symptom during the transition period to menopause. Such women suffer from decreased quality life, sleep disturbances or depressed mood. The most effective method treating is hormonal treatment, although it carries potential risks, because real link has been established between...

in schizophrenia, neurocognitive functions are one to two standard deviations below the normal controls and these deficits have a significant relationship with overall functioning and poor outcome. according to this fact, it is important to investigate the factors that effect neurocognition in schizophrenic patients. this study was carried out to demonstrate the relationship between attention/v...

Degradation of plant patches is considered as one of the indices for rangeland degrading health condition. Investigating the accuracy of triple indices (infiltration, stability and soil nutrient cycle) presented by LFA method seems necessary to determine its efficiency in semi-arid areas with the least cost. This study aims to investigate the role of vegetative species and growing forms on soil...
