    Spatial-temporal pattern of cultivated land productivity based on net primary productivity and analysis of influencing factors in the Songhua River basin حسب Yang, Shiliang

    منشور في 2022
    "…The results showed that: (1) the area of cultivated land in SRB decreased, but NPP of cultivated land area increased, during 2000-2020; (2) spatially, NPP was relatively low in the middle of the basin and gradually increased towards the periphery; (3) The main positive factors were the normalized difference vegetation index (NDVI), slope, precipitation, evapotranspiration, and total nitrogen, while the main negative factors were temperature, Ratio Vegetation Index, and total phosphorus. …"

    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
    "…Results obtained show that mono-crystalline PVs have efficiencies as high as 85% compared to 70% for amorphous ones. Also, dust accumulation degrades more critically the efficiency of amorphous and mono-crystalline silicon PVs than the panel's temperature or relative humidity. …"

    Vertical zonation and functional diversity of fish assemblages revealed by ROV videos at oil platforms in The Gulf حسب Torquato, F.

    منشور في 2017
    "…Several trends were uncovered in the vertical distribution of the fish community; most species were observed between 20 and 50 m depth and fish abundance decreased towards the bottom, with the highest abundances recorded in the upper layers, i.e. down to 40 m depth. …"

    New genetic insights into improving barley cope with salt stress via regulating mineral accumulation, cellular ion homeostasis, and membrane trafficking حسب Samar G., Thabet

    منشور في 2023
    "…Significant phenotypic variation was detected among the accessions in response to salt stress. Application of 1 mM Se-NP enhanced thousand kernel weight (TKW) by 28% while decreasing the Na+ contents in the flag leaves by 53% . …"

    Seroprevalence of camel brucellosis in Qatar حسب Alhussain, Hashim

    منشور في 2022
    "…Camels below breeding age (i.e., < 4 years old) showed decreased seropositivity (3.4%, 95% CI, 0.1–17.8), compared to (22.8%, 95% CI, 17.4–29.0) seropositivity in camels ≥ 4 years of age, with a significant association between age groups and seropositivity (P = 0.02). …"

    Simulation and Optimization of an LNG Plant Cold Section حسب Katebah, Mary Anna

    منشور في 2018
    "…Among all the available cycles, the propane pre-cooled mixed refrigerant (C3MR) system is the leading one in the LNG industry. Therefore, this research focuses on decreasing the energy consumption of C3MR and NGL recovery system with helium extraction (producing approximately 60 mol% crude helium) and nitrogen rejection units. …"
