    Study of the effects of dust, relative humidity, and temperature on solar PV performance in Doha: Comparison between monocrystalline and amorphous PVS by Touati F.A.

    Published 2013
    “…It was estimated that 100 days of dust accumulation over monocrystalline PV panels, caused the efficiency to decrease by around 10%. This limitation makes solar PVs to represent an unreliable source of power for unattended or remote devices and thus strongly suggests the challenge of cleaning the panel's surface regularly or injecting technical modifications. …”

    Fabrication of Selective Sensors for Hg2+ Traces in Water Using Graphene Decorated with Metal Nanoclusters by Ayesh, Ahmad I.

    Published 2016
    “…The sensing mechanism of the graphene-based sensors can be summarized as follows: exposure of the graphene sensor to Hg2+ ions decreases electron concentration in the n-type graphene, thus, the conductance of the sensor decreases. …”

    Flow and Fracture Behaviour of Tungsten Fiber Reinforced Superalloy Composites-Effect Of Specimen Geometry by Kandeil, A. Y.

    Published 1989
    “…I. niaxial compression forging was performed at a constant true strain rate of 3x10^ S , with temperature as parameter. The aspect ratio (wo/ho) of test blanks was made to vary between 0.3 and 3, loading being always normal to the direction of wire alignment. …”
