    Opis:
    Obtaining a lateral S-parameter image scan from positrons implanted into semiconductor devices can be a helpful research tool both for localizing device structures and in diagnozing defect patterns that could help interpret function. S-parameter images can be obtained by electromagnetically rastering a variable energy positron beam of small spot size across the sample. Here we describe a general hardware and software architecture of relatively low cost that has recently been developed in our laboratory which allows the whole sub-surface S-parameter image of a sample or device to be obtained in real time. This system has the advantage over more conventional sequential scanning techniques of allowing the operator to terminate data collection once the quality of the image is deemed sufficient. As an example of the usefulness of this type of imaging architecture, S-parameter images of a representative sample are presented at two different positron implantation energies.

    Opis:
    Putting a Y-capacitor between the primary ground and secondary ground is a common practice in industry to reduce EMI; but, this capacitor increases touch current. A method is discussed to measure the touch current at circuit design level. An optimum value of Y-capacitor is predicted without exceeding touch current limit. Experimental results of touch current measurements and EMI measurements are analyzed.

    Opis:
    Fossil fuels plays vital role in the development of the nation. The limitation of the Non-renewable energy required alternative energy sources such as solar, wind energy, hydro energy and biomass energy etc., and these renewable energies are eco-friendly in nature. The study has conducted for the determination of fatty acid profile in Jatropha curcas oil, determination of restriction sites in genomic DNA of Jatropha curcas, comparison of DGAT gene sequence alignment of different plants using Clustal W software. and PCR amplification of DGAT gene. The results confirmed that the solvent extraction produced high quality oil. From the thin layer chromatography plate, the saturated fatty acid like Linoleinic acid (0.14), Palmatic acid (0.38), Stearic acid (0.72), and unsaturated fatty acid like and Oleic acid (0.90) were identified. The genomic DNA was restriction digested with EcoRI, BamHI, PstI, HindIII. The observed that restriction bands for EcoRI was 3 sites and for Hind III was 1 site respectively. The amplification of gene encoding DGAT gene from the genomic DNA was carried out by polymerase chain reaction and also by bioinformatics software and was found to be approximately 2 kb size. Our study makes initial step for altering of the Jatropha seed oil for enhancing the oil content level.

    Opis:
    Boron nitride (BN) reinforced Al6061 aluminum-based composites are synthesized by conventional stir casting method followed by exposure to hot extrusion. The optical images confirmed the distribution of BN nanoparticles in the aluminum alloy matrix. The concentration of BN is varied from (0.5, 1.5, 3, 4.5, 6, 7.5, and 9 wt%) in the composites and its effect on the tensile strength was investigated. The results revealed that both extruded and heat-treated composites specimens showed enhanced toughness and tensile strength by increasing BN nanoparticle concentration. The heat-treated composite samples showed lower flexibility of up to 40%, and further, it exhibited 37% greater hardness and 32% enhancement in tensile strength over the extruded sample. The tensile properties of Al6061-BN composites were evaluated by temperature-dependent internal friction (TDIF) analysis and the results showed that the as-prepared composite's strength increased with temperature.
