    Optimization Of The Electronic And Optical Properties Of Tio2 For Clean Fuel Production by Fadlallah, Mohamed

    Published 2014
    “…However, the long-standing bottleneck is the fact that TiO2 is a wide band gap semiconductor, limiting its activation to the deep-blue and ultraviolet spectral region that contains but a small fraction (5%) of the incident solar energy. …”

    Magneto-Mechanical and Thermal Properties of Nd-Fe-B-Epoxy-Bonded Composite Materials by Grujić, Aleksandar

    Published 2023
    “…This examination of synthesized Nd-Fe-B-epoxy composite materials includes the mutual comparison of impact toughness, fatigue, and the structural, thermal, dynamic-mechanical, and magnetic behavior of materials with different content of magnetic Nd-Fe-B particles, in a wide range from 5 to 95 wt.%. This paper tests the influence of the Nd-Fe-B content on impacting the toughness of the composite material, as this relationship has not been tested before. …”

    Insights Into the Role of CircRNAs: Biogenesis, Characterization, Functional, and Clinical Impact in Human Malignancies by Nisar, Sabah

    Published 2021
    “…Compared to the linear RNA, circRNAs are produced differentially by backsplicing exons or lariat introns from a pre-messenger RNA (mRNA) forming a covalently closed loop structure missing 3′ poly-(A) tail or 5′ cap, rendering them immune to exonuclease-mediated degradation. …”

    Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process by Reddya, M. Penchal

    Published 2017
    “…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …”

    Energy conversion of heat from abandoned oil wells to mechanical refrigeration - Transient analysis and optimization by Al-Khawaja, Mohammed

    Published 2012
    “…Results show that at realistic and conservative conditions, the geofluid temperature considerably decreases for the first four months of operation (by an average of 30 °C) and tends to be constant after half a year of operation. …”

    From the Renewed Policy of Sport Mega Events to Prosumerism: Articulating the challenges faced by the 2022 FIFA World Cup in Qatar by Bretherton, Paul

    Published 2022
    “…These changes in the bidding and organisation of SMEs can be seen as examples of prosumerism, which refers to "the tendency towards a market where the distinction between producers and consumers decreases, where consumers are producing their own goods and services" (IGI Global, 2022, para. 2). …”

    The Association between Zinc and Copper and Cardiometabolic Risk Factors in Adults by Al Kudsi, Dana Samir

    Published 2021
    “…High Zn/Cu ratio increased the prevalence of low HDL (4.508; p?0.001) and MetS (5.570; p?0.01). These findings suggest that high Cu levels are associated with a protective effect on DBP, HDL, and MetS and that high plasma Zn/Cu ratio is associated with the risk of low HDL and MetS. …”
