    Towards understanding the effects of climatic and environmental factors on solar PV performance in arid desert regions (Qatar) for various PV technologies حسب Touati F.

    منشور في 2012
    "…It was estimated that 100 days of dust accumulation over mono-crystalline PV panels, caused the efficiency to decrease by around 10%. This limitation makes solar PV 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. …"

    Dietary L-carnitine and vitamin-E; a strategy to combat ochratoxin-A induced immunosuppression حسب Bhatti S.A.

    منشور في 2018
    "…This study aimed to evaluate the effect of dietary ochratoxin A (OA), in the presence and absence of L-carnitine (LC) and vitamin E (VE), on the humoral immune responses of White Leghorn cockerels (WLC). One-day old white male Leghorn chicks were divided into 12 groups, having 20 birds each and were offered ration contaminated with OA (1.0 or 2.0 mg/kg feed) alone and concurrently with LC (1.0 g/kg) and/or VE (0.2 g/kg), for 42 days. …"
