Constant quality improvement through automation of production processes is an important prerequisite for increased viability mining machines and plants. Factors that limit the cutting machining operations include problem controlling chip formation crushing. Solution this necessitates theoretical description material conditions tools with curvilinear surfaces. The paper describes basic principle...

Contiguous graphite fins can be grown with Microwave Plasma CVD from the surface of different types of thermally conductive (TC), graphite fibers. The fins grow from all fiber filaments in multiple same TC graphite fiber tow bundles. Fin morphology consists of contiguous branching graphene basal planes originating from the fiber’s surface and curling outwards regardless of the fiber’s isotropic...

The aim of this study was to determine the daily noise exposure levels in black tea processing factories and evaluate its effects on employees' occupational health safety. In study, sound pressure level dBA values were measured at ear employees each production unit three operating Artvin Province. These where measurements made consist withering, curling, oxidation, drying (boiler stove) classif...

Soft actuators driven by pneumatic pressure are promising actuators for mechanical systems in medical, biological, agriculture, welfare fields and so on, because they can ensure high safety for fragile objects from their low mechanical impedance. In this study, a new rubber pneumatic actuator made from silicone rubber was developed. Composed of one chamber and one air-supply tube, it can genera...

When a straight rod is bent and suddenly released on one end, a burst of dispersive flexural waves propagates down the material as predicted by linear beam theories. However, we show that for ribbons with a longitudinal natural radius of curvature a0, geometrical constraints lead to strain localization which controls the dynamics. This localized region of deformation selects a specific curling ...

Buckminsterfullerene (C60) represents a perfect combination of geometry and molecular structural chemistry. It has inspired many creative ideas for building fullerene-like nanopolyhedra. These include other fullerenes, virus capsids, polyhedra based on DNA, and synthetic polynuclear metal clusters and cages. Indeed, the regular organization of large numbers of metal atoms into one highly comple...
