The cilium of a vertebrate photoreceptor cell connects the phototransductive outer segment of the cell to the inner segment. Previous studies have shown that, within the connecting cilium, there is a small cluster of actin filaments, which play a critical role in the formation of new disk membranes. Here, we have detected a polypeptide in rat rod outer segments that is recognized by myosin heav...

Insulation pull rods are commonly used tools and instruments in the replacement of insulators for live work. Traditional hard insulated difficult to transport assemble due their large deflection, especially long heavy weight UHV operations, difficulties above links more obvious. In view existing problems use rods, by studying overall processing type, soft rod weaving process, technology tightly...

A new-style transplanter’s planting mechanism was designed, which was composed of Planetary Gear, Planetary Carrier, Connecting rod, Groove cam and Planting arm. Built the kinematics model and determined the main parameters which influenced the Plant-arm’s locus by analyzing of the Kinematic model. Created the 3D Model in PRO/E and imported it into the Kinematics simulation software ADAMS, anal...

in iran, onion plants are currently broadcast over the majority of onion fields and weeding and harvesting are done manually by seasonal workers. at harvest time, 40 worker-days are required to onion dig just one hectare. this cost could be saved if the operation could be carried out by machine. rear-mounted diggers can only be implemented if 40 cm spacing between rows is allowed for each tract...
