to study the population structure of decapods in the intertidal zone of bushehr rocky shores, some random sample collection from four rocky and rubble shores of bushehr were done using a 50×50 quadrates sampling unit, in four successive seasons from autumn 2009 to summer 2010. totally 8 speciesbelonging to 5 family of decapods were identified and counted. in the whole course of sample collectio...

lenses are often used to converge electromagnetic wave namely they convert incident phase front of feed antenna to a flat phase front. together, the lens and the feed create an electrically large aperture antenna. flat lenses provide the cost and weight benefits of the reflect-arrays, while maintaining the advantages of a lens antenna. these lenses use an array of unit-cells which are excited b...

the complex of ce(iii), [ ce (phensc) (h 0) ] (c10 ) , was synthesized using the phensc, a hexadentate ligand,2,9-diformyl-1,lo- phenanthroline bis (semicarbazone), and characterized by x-ray diffraction. the cerium atom has an unusual coordination number of ten involving six donor atoms of the planar ligand in the equatorial plane and four oxygen atoms from four axial water molecules. the comp...

BACKGROUND The shape diversity of 16.4 million biologically relevant molecules from the PubChem Compound database and their 1.46 billion diverse conformers was explored as a function of molecular volume. RESULTS The diversity of shape space was investigated by determining the shape similarity threshold to achieve a maximum on the count of reference shapes per unit of conformer volume. The rat...

In this paper, closed-form expressions for the capacities per unit bandwidth for generalized Rician fading channels are derived for power and rate adaptation, constant transmit power, channel inversion with fixed rate, and truncated channel inversion adaptation policies. The closed-form solutions are derived for the single antenna reception (without diversity combining) and maximal-ratio combin...

Prior research on demographic diversity in work teams has yielded mixed results, with the effects of team diversity ranging from positive to neutral to negative. This article shows that an improved understanding of the relationship between team diversity and team performance can be reached by considering the combined effects of team diversity and demographic social context. We hypothesized that...

The Shaker locus of Drosophila contains a very large transcription unit. It is expressed predominantly in the nervous system by multiple, differential as well as alternative, splicing mechanisms into different, but functionally related proteins. The structure of the Shaker transcription unit and the properties of the encoded Shaker protein family provide a molecular basis for A channel diversit...

The 2-(methylamino) pyridine, L, reacts with CuCl in THF to give hexameric copper (I) complex, [CuCl(L)]6. The molecular structure has been determined by using single-crystal X-ray diffraction method. The complex crustallizes in the monoclinic space group P21/n with four molecules per unit cell. The unit cell dimensions are a = 8.3495 (15), b = 15.622 (6), and c = 17.0...
