    Long-term performance analysis and power prediction of PV technology in the State of Qatar حسب Touati F.

    منشور في 2017
    "…Results show that due to panel dusting for eight months, the PV output power decreased by 50%. Also, owing to lower ambient temperatures, clearer sky and cleaner panels due to occasional rainfall, the PV panels show higher output power in Winter than in Summer season. …"

    Effect of surfactant and electron treatment on the electrical and thermal conductivity as well as thermal and mechanical properties of ehylene vinyl acetate/expanded graphite compo... حسب Sefadi, Jeremia Shale

    منشور في 2015
    "…The thermal conductivity linearly increased with EG content, and this increase was more pronounced in the case of SDS-EG, but decreased after EB irradiation. The thermal properties were little influenced by EB irradiation, while better polymer–filler interaction and better filler dispersion as a result of SDS treatment, and the EB irradiation initiated formation of a cross-linked network, had a positive effect on the tensile properties.…"
