Cold pressing

Alumium (Al) - based materials are highly demanded for automobiles, transportation, and aerospace etc. In this research, Al - based TiC composites were fabricated using powder metallurgy (P/M) technology from Al, Cu, and TiC powders with the compositions of Al - 5 wt.% TiC, and Al - 5 Cu/ 5wt.% TiC. The composite powders were well mixed and compacted using cold pressing technique with an applied pressure of 500 MPa.

This study focuses on 316L stainless steel fabricated by selective laser melting (SLM) in the context of nuclear application, and compares with a cold-rolled solution annealed 316L sample. The effect of heat treatment (HT) and hot isostatic pressing (HIP) on the microstructure and mechanical properties is discussed.

A case study was conducted by Agricultural Extension Education Center, Koppal with an innovative ground nut grower and small scale entrepreneur for a period of two years. Cold press oil extraction unit established by the farmer could successfully extract 3.60 tons of oil seeds in a month with a net savings of Rs. 16485. The unit became self sustain in a span of one year and could generate employment of 365 man days. The consumers are satisfied with the quality and purity of oil which they purchased for consumption.

A refined analytical method has been developed for the determination of the isotope ratio of oxygenated compounds in essential oils, using high-resolution gas chromatographymass spectrometry (HRGC-MS), has been developed. Thirty-three samples of yuzu fruits from different production areas in Japan and South Korea were collected and prepared for cold-pressed peel oils. The oils were analysed by HRGC-MS for linalool concentration and isotope ratio based on the peak intensities of (M+2)+ , (M+1)+ and M+ ions.

Challenges to the effectiveness of specific activities and production technologies in agriculture become more pressing each day as worldwide demand for agricultural products increases. The mechanization of agriculture brings positive quantitative and qualitative effects however, the modernization of production tools (tractors and agricultural machinery) needs to be directly linked to increasing economic efficiency of use.

In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5.15 %, 7.31 %, 9.84 % and 40.79 % respectively. In addition, holocellulose, cellulose, lignin and ash contents were found as 74.79 %, 52.67 %, 20.17% and 4.21 % respectively.

Introduction: On 23 March 1989, electrochemists M. Fleischmann and S. Pons claimed in a press conference at the University of Utah that they had achieved nuclear fusion in a tabletop chemistry experiment. Since then, evidence of fusion in what is now called low-energy nuclear reaction (LENR) research has grown only slightly stronger. Their hypothesis that a novel form of thermonuclear fusion was responsible for their experimental results is still unproved.
