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...

CFCs, HCFCs are stipulated to phase out, and other alternative refrigerants like R134a, are also constrained as a result from their high GWP values. CO2 as a natural working fluid now is used in reciprocating compressors due to its uniquely beneficial properties (ozone depletion potential, ODP=0; global warming potential, GWP =1). However, one remarkable characteristics of the CO2 reciprocating...

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...

Monoclonal antibodies specific for the rod region can affect smooth muscle myosin's motor properties. Actin movement by phosphorylated myosin was inhibited by an antibody (LMM.4) which binds to the COOH-terminal end of the coiled-coil rod, a region thought to be involved in filament assembly. The actin-activated ATPase activity of the myosin-antibody LMM.4 complex was also reduced 10-fold at ac...

Abstract As con-rod is a critical component in an engine, its reliability overwhelmingly directly affects the performance of whole diesel engine. The fretting wear bushing mainly occurs on contact surface with small end and cap. In proposed study, process end, cap under maximum combustion pressure condition was analyzed, distribution friction stress analyzed. Then orthogonal simulation test des...

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...

We present a newmeasuring probe based on a miniature fiberoptic pressure sensor that can measure esophageal variceal pressure. The probe consists of an outer flexible chamber filled with a pressure transmission medium, at the center of which is positioned the fibreoptic sensor with diameter of 0.5mm (FOP-F125, FISO Technologies Inc., Quebec, Canada) (●" Fig.1). The single-column, flexible chamb...

In cases of completely conforming frictionless contact, the contact area generally either decreases or stays the same under load, in which case the extent of the contact area is subsequently independent of load and the stress and displacement fields vary linearly with the loading parameter. Dundurs and Stippes describe such cases as receding contact problems. Here, we demonstrate that similar r...
