    Concrete Pavement Truck Equivalence Factors For Upgrades حسب Razouki, Sabah Said

    منشور في 1999
    "…Presented in this paper are the upgrade truck equivalence factors for single unit trucks of type, 1.2 and 1.22 which are not covered by AASHTO. The equivalency factors for front and rear axles of single unit trucks were developed using AASHO Road Test equation after considering the decrease in front axle load and the increase in rear axle load due to the axle load redistribution on upgrades. …"

    Variation in temperature and light but not salinity invokes antioxidant enzyme activities in germinating seeds of Salsola drummondii حسب A. Rasheed,A. Hameed,M. A. Khan &B. Gul

    منشور في 2016
    "…We therefore studied lipid peroxidation and antioxidant responses of a leaf-succulent halophyte Salsola drummondii during seed germination under different salinity levels (0, 200 and 800 mM NaCl), temperature (10/20, 20/30 and 25/35°C) and light regimes. Seeds absorbed water and germinated in less than 1 h in non-saline control while increases in salinity decreased the rate of water uptake as well as seed germination. …"

    Changes in Copepod Community Structure in Response to Land-Based Activities along Alexandria Coastline, Mediterranean Sea حسب El Din, Nehad M. Nour [نهاد مصطفى نور الدين]

    منشور في 2000
    "…Industrial discharge exerted the highest impact on the copepod population by decreasing its density to less than 500 ind./m3. Despite the decrease m copepod abundance during high flow of sewage, the impacted area sustained the maximum copepod density low discharge i.e. 11,222 ind.…"

    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. …"
