    Antiferromagnetism in EuPdGe3 by Albedah, M.A.

    Published 2014
    “…EuPdGe3 crystallizes in the BaNiSn3-type tetragonal structure (space group I4mm) with the lattice constants a=4.4457(1)Å and c=10.1703(2)Å. The results are consistent with EuPdGe3 being an antiferromagnet with the Néel temperature TN=12.16(1)K and with the Eu spins S=7/2 in the ab plane. …”

    Structural performance and moment redistribution of basalt FRC continuous beams reinforced with basalt FRP bars by Abushanab, Abdelrahman

    Published 2021
    “…A total of 10 reinforced concrete (RC) continuous beams over two equal spans of 1800 mm were tested under five-point loading until failure. The test variables were the type of main bars, sagging-to-hogging reinforcement ratio, volume fractions (Vf) of basalt macro fibers (BMF), and stirrups spacing. …”

    Investigating the effect of the air inlet temperature on the combustion characteristics of a spark ignition engine fueled by biogas by Ebrahemi, Abdullah Ebrahem

    Published 2020
    “…This work has conducted a numerical study using AVL-Boost engine simulation utilizing biogas (CH4 and CO2)–air mixtures in a SI engine model. The effect of varying the air manifold temperature from 25 to 50°C on the combustion characteristics as well as engine performance under full load condition in a SI engine fueled by gasoline and biogas mixtures has been investigated. …”

    Fabrication and Investigation of Graphite-Flake-Composite-Based Non-Invasive Flex Multi-Functional Force, Acceleration, and Thermal Sensor by Fatima, Noshin

    Published 2023
    “…Sensor impedance was measured from DC to 200 kHz at up to 20 gf, 20 m/s2, and 26–60 °C. Sensor resistance and impedance to stretching force and acceleration at DC and 200 Hz rose 2.4- and 2.6-fold and 2.01- and 2.06-fold, respectively. …”

    Impact of trace noble metals on the catalytic performance of LaNiMgO towards methane dry reforming by Mohamed, Assem T.

    Published 2024
    “…The incorporation of noble metals enhanced Ni dispersion on the support and facilitated the Ni reducibility due to the H2 spillover effect. At 650 °C and in the early stages of the reaction, all catalysts exhibited enhancement in the catalytic activity. …”

    Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather by Oualha, Meriam

    Published 2020
    “…Their optimal potentials was at wide ranges of temperature from 30 °C to 42 °C and pH from 7.0 to 8.0. Using Qatari bacteria in liquid cultures and at syringe level at laboratory conditions, as well as in plots at field conditions, 16% CaCO3 increase in minerals formation was obtained, leading to 7% increase of soils stability. …”

    The investigation of treatment design parameters on carbon integration networks by Alnouri, Sabla Y.

    Published 2023
    “…Furthermore, it was discovered that for net capture targets of 20% and 25%, no revenue from carbon storage could be generated beyond a solvent temperature of 25 °C. Additionally, the optimal diameter of the treatment column was more responsive to changes in solvent temperature for cases with low net capture targets (below 10%), while its sensitivity decreased for higher capture targets (above 10%). …”
