    Opportunities, challenges and trade-offs with decreasing avoidable food waste in the UK حسب Patel, Shivalee

    منشور في 2021
    "…Stakeholder interrelations, regulatory and socio-economic aspects are discussed in relation to their influence on decreasing avoidable food waste. The main output from this work is a diagrammatic depiction of where challenges and trade-offs occur along the food supply chain, and how policy and socio-economic reforms are needed to maximise avoidable food waste prevention, and the surplus avoidable food redistribution in the food supply chain for social benefit.…"

    Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process حسب Reddya, M. Penchal

    منشور في 2017
    "…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …"

    Viscosity of Al2O3-water nanofluids حسب Anish, W.

    منشور في 2020
    "…The existing experimental result about the viscosity of nanofluids shows clearly that the viscosity augmented accordingly with an increase of additive concentration and decreased with the temperature rise. In this paper, different characteristics of viscosity of nanofluids are compiled and the viscosities of Al2O3-water nanofluids are estimated by Matlab approximation.…"
