We study the effect of electrostatic interactions on the distribution function of the end-to-end distance of a single polyelectrolyte chain in the rod-like limit. The extent to which the radial distribution function of a polyelectrolyte is reproduced by that of a wormlike chain with an adjusted effective persistence length is investigated. Strong evidence is found for a universal scaling formul...

A nets fixing device embedded in a circular floating net cage is presented this paper, it consists of arc metal rods, wire ropes and sleeves. The rod with connecting plate at both ends shroud ring the inner side middle. Multiple rods can be fixedly connected to form shape; During assembly, each assembled into ring. rope bound on rod, then pulled sink water inside cage. Then, depth range nets, i...

The connecting rod is one of the most important moving components in an internal combustion engine. present work determined possibility using aluminium alloy 7075 material to design and manufacture a for weight optimisation without losing strength rod. It considered modal thermal analyses investigate suitability design. parameters that were under analysis were: total deformation, natural freque...

The use of lectin cytochemistry together with proteolytic digestion techniques to partially characterize lectin binding sites of several intracellular compartments in frog photoreceptors was studied. Uniform access of reagents to all intracellular compartments was obtained by performing the experiments directly on semithin sections of retinal tissue embedded in a hydrophilic plastic resin. Prot...
