umen tympanic due to metallic or non metallic (mostly polythene material) are among the most common cause of gastro intestinal disorders in ruminants (Radostatis etal, 1994). Plastics can be termed as wide range of chemical materials either synthetic or semi synthetic solidmaterials like polyethylene,polyvinyle chloride,polysterine largely used in plastics manufacturing industry which pose a th...

Most of the metal additive manufacturing technologies are focused on high cost and high end applications. There is in need, a low cost additive manufacturing technology suitable for low and high end metallic applications. Robotic automated welding can be considered as an alternative to manufactured large scale metal parts with layer by layer approach. However, many obstacles have to be overcome...

Materials research plays a vital role in transforming breakthrough scientific ideas into next-generation technology. Similar to the way silicon revolutionized the microelectronics industry, the proper materials can greatly impact the field of plasmonics and metamaterials. Currently, research in plasmonics and metamaterials lacks good material building blocks in order to realize useful devices. ...

Mechanical interlocking is widely applied in industry and general lives of human beings. In this work, we realized the control of locking or sliding states of cotton fibers on the metal surfaces with slightly different textures through traditional machining. Three types of sliding states, i.e., locking, one-way sliding, and two-way sliding have been achieved. It is found that the locking or sli...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

It has been previously established that lung cancer could be induced in rats by exposure to radon and radon daughters. Although the oat-cell carcinomas that are common in humans were not found in rats, other histological types of lung carcinomas, especially squamous cell carcinomas and primitive lung adenocarcinomas, were similar to those observed in humans. A dose-effect relationship was estab...

Metallic contamination was key to the discovery of semiconductor nanowires, but today it stands in the way of their adoption by the semiconductor industry. This is because many of the metallic catalysts required for nanowire growth are not compatible with standard CMOS (complementary metal oxide semiconductor) fabrication processes. Nanowire synthesis with those metals that are CMOS compatible,...

Dense (>98 th%) and homogeneous ceramic/metal composites were obtained by spark plasma sintering (SPS) using ZrO2 and lamellar metallic powders of tantalum or niobium (20 vol.%) as starting materials. The present study has demonstrated the unique and unpredicted simultaneous enhancement in toughness and strength with very high flaw tolerance of zirconia/Ta composites. In addition to their excel...

Scheelite is a calcium tungstate mineral (CaWO4) well known in the mining industry as a source of tungsten. This mineral fluoresces under shortwave UV and X-rays excitation with a characteristic blue luminescence centered at about 425 nm. CaWO4-based powder was commonly used as blue phosphor and scintillator (due to high Z of W) [1-3]. The emitted spectrum shifts to yellow in the presence of mo...
