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...

We consider the elastic rod of a large mass M , the left end of which is fixed to a body of mass m << M and the second body of mass m is fixed to the right end of the rod. The force of the delta-function form is applied to the left side of the rod. We find the propagation of the pulse in the system. Our problem represents the missing problem in the Newton “Principia mathematica” and in any text...

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...

Morphology of structural components of nuclear polyhedrosis virus (NPV) particles of the silkworm (Bombyx mori Linné) was studied by electron microscope using negative staining. NPV particles isolated from polyhedra could be separated into five structural components by centrifugation in sucrose density gradients. The lowest band (band I) was found to consist of thick rod-shaped particles (330 b...

The provides portable positive displacement pump demonstrating movement fluids laboratory. component consists atransparent piston-cylinder assembly, suction pipe, delivery valve, crank, and connecting rod mechanism...

Abstract. A new approach of the Polarity Effect in connection to the Corona Current and the Ground Effect in small rod-plate and rod-rod air gaps is presented. The influence of the polarity of the applied voltage to the corona onset voltage or the breakdown voltage of small rod-plate and rod-rod air gaps is investigated. The influence of the grounding of one of the electrodes, to the field dist...

Intercellular bridges first appear during lizard oogenesis when follicles are rather small (150 microgram in diameter); at this stage they form connecting links between the oocyte and follicle cells, which have not yet differentiated into pyriform cells. Later on, when the follicles have become larger (1 mm) and the follicular epithelium appears constituted by 3 types of cells (small, intermedi...
