Each day, rod photoreceptors of the vertebrate retina synthesize rhodopsin and insert it into new membranes of the rod outer segment (ROS). The authors determined which components of the rod cell transport opsin from the Golgi to the ROS by a combined EM autoradiographic and immunocytochemical study using radiolabeled amino acid precursors and antiopsin antibodies. Radiolabeled proteins in the ...

Nowdays, motorcycles become a primary need for people, especially in Indonesia. This has resulted the increasing number of motorcycle spare parts waste. The waste is form components such as wheels, tires, drums, canvas, gear, chains and pistons many others. Until now, community not used this waste, use raw material casting connecting rods. Connecting rod itself component made aluminum. In study...

The article presents the results of an experimental study and analytical evaluation calculations to check service life increase durability needle bearing piston head connecting rod a transport diesel engine. primary reasons for violation nominal operation main units this mechanism have been established. Corresponding recommendations are proposed carrying out accelerated tests durability, reduci...

Calpain II was purified to apparent homogeneity from bovine neural retinas. It was found to be biochemically similar to brain calpain II, purified by the same procedure, with respect to: subunit mobility in SDS-polyacrylamide gel electrophoresis; Ca2+ sensitivity; inhibition by calpeptin and other cysteine protease inhibitors; and optimal pH. Semithin cryosections were immuno-labeled with antib...

The retina of the adult rabbit contains two types of photoreceptors. Type I predominates and is a typical rod. The identity of the type II cell has been uncertain until now. This study demonstrates that the type II cell has certain conelike morphologic features including a pale nucleus, complex synaptic pedicel, and multiple wrappings of the outer segment by microvilli of the pigment epithelium...

This work deals with the modelling of lubricated revolute joints in multibody mechanical systems. In most machines and mechanisms, the joints are designed to operate with some lubricant fluid. The high pressures generated in the lubricant fluid act to keep the journal and the bearing apart. Moreover, the thin film formed by lubricant reduces friction and wear, provides load capacity and adds da...
