Several in vitro studies employ the confection of cavity preparations that are difficult to standardize by means of manual high speed handpieces. This study presents the development of a cavity preparation machine designed to standardize in vitro cavity preparations. A metal base of 25 mm x 25 mm x 4 mm (length x width x height) was coupled to a small mobile table which was designed to be able ...

The connecting rod is a major link inside of the combustion engine. It connects piston to crankshaft and responsible for transferring power from crankshaft. has work on higher r. p.m. because which it bear severe stresses make its design vital internal In this paper, two-wheeler designed by analytical method. On basis that physical model created in Solid Works. Structural system been analysed u...

Small end bearings are a critical component of reciprocating engines, and the performance their lubrication directly affects engines’ reliability mechanical efficiency. There many factors that influence lubrication. A new type small-end bearing test rig was developed to reveal key influencing on characteristics, multi-body dynamic model coupled with elastohydrodynamic (EHD) characteristics buil...

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...

Abstract As an important bearing structure of maglev train, the connecting rod has high requirements for material performance. In this paper, according to structural capacity rod, finite element methodwas used calculate and analyze composite aluminum alloy under two working conditions, so as determine advantages in mechanical properties provide theoretical support design rod.

Automobile internal combustion engine connecting rod is a high volume production component subjected to complex loading. Proper optimization of this component, which is critical to the engine fuel efficiency and more vigorously pursued by the automotive industry in recent years, necessitates a detailed understanding of the applied loads and resulting stresses under in-service conditions. In thi...

Kinesin superfamily proteins (KIFs) are probable motors in vesicular and non-vesicular transport along microtubular tracks. Since a variety of KIFs have been recently identified in the motile flagella of Chlamydomonas, we sought to ascertain whether KIFs are also associated with the connecting cilia of vertebrate rod photoreceptors. As the only structural link between the rod inner segment and ...

The connecting rod (CR) is the main moving parts and an important component of engine. If the reliability is not strong enough, fatigue failure of the CR would occur, thereby leading to component fracture and engine failure. So much so that CR fracture. It will lead to engine fault as well as serious outcome. In this paper, stress distribution and fatigue life of CR in light vehicle engine were...
