Introduction
It is well-known that the mechanical properties of materials under dynamic loading are different remarkably from that under quasi-static case.
Thus, the characterization of dynamic mechanical properties of wheel/rail materials is required and important for designing and assessing the safety of the wheel-rail system.
Over the last several decades, there are a number of constitutive models (i.e., empirical, semi-empirical and physically-based models) were proposed to depict the dynamic plastic behavior of materials.

It may substitutes proportionally of raw materials and be functional feed for ruminant.
Introduction Loh (2002) [1] reported that the use of local raw materials in production of animal feed in Malaysia needs more innovative R&D for ruminant industry.
Thus far, bulk of raw materials for production of animal feed and also commercial animal feeds are imported from other countries and as consequences, these contributed to high cost of animal feed in livestock industry.
Current technology in evaluating, processing and utilisation of new materials becomes more advance thus provides numerous opportunities in production to minimize the feed costs [3].
Materials and Methods The microorganism used in this study was Lactobacillus rhamnosus NRRL 442.

Evaluation of the antibacterial properties of PVC materials used, in particular, in medicine, is becoming increasingly important due to increased sanitary and hygienic requirements.
Broad antimicrobial activity and surfactant properties have made quaternary ammonium compounds the preferred additives for PVC medical grade materials [7].
Experimental Details PVC materials were obtained on the basis of EP-6602-C emulsion polymer (GOST 14039-78).

Surface properties of K9 glass/diamond materials were controlled under the optical brittle material by cold plasma assisted cutting machining.
Cold plasma jet can regulate and control the K9 glass/diamond materials surface property and improve anti-friction effect.
During the process, the cold plasma materials have many favorable processing properties.
There has nothing about high temperature thermal damage on the surface of the material or reduction the mechanical properties of materials.
This approach can increase critical cutting depth, and enlarge cutting material plastic domain thereby to prolong brittle fracture of materials.
