    Utilizing Recycled Polypropylene Fibers as Reinforcement for Concrete Beams by Bendjillali, Khadra

    Published 2020
    “…The various fiber content ratios tested in this investigation are 0.25, 0.5 and 1%. Based on the results of this study, the presence of recycled PP fibers in concrete decreases its workability; the addition of an adequate superplasticizer to the concrete mix becomes then necessary. …”

    Re-emission of slow positrons from tungsten at elevated temperatures by Al-Qaradawi, I. Y.

    Published 2002
    “…Irrespective of target history, no sharpening of the energy spectrum of re-emitted positrons was observed as the remoderator temperature was increased. Further, a steady decrease in the apparent re-emitted positron intensity was observed, attributed primarily to the increase in positronium formation, as the temperature of the foil was increased from 20 to 500 °C. …”

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

    Published 2021
    “…Seven beams were longitudinally reinforced with BFRP bars, while the remaining three beams were reinforced with conventional steel bars and served as a control. Test results showed that BFRC-RC beams had higher crack widths, mid-span deflections, and strains than steel-RC beams. …”

    Effects of soaking, acidity and temperature on cadmium and lead removal from rice by Al-Naimi M.

    Published 2020
    “…Results showed that few samples have shown lead concentrations above the maximum limit set by the World Health Organization (WHO) and the UN Food and Agriculture Organization (FAO) of 0.2 mg/kg, whereas, all cadmium concentrations were below the limit of 0.4 mg/kg. A decrease in lead and cadmium concentrations were observed with increasing time of soaking. …”

    Absorption of CO2 in aqueous blend of methyldiethanolamine and arginine by Talkhan, Ahmed Gomaa

    Published 2020
    “…The experimental results showed improved solubility of CO2 with the addition of Arg at CO2 partial pressures below 20 kPa. However, for CO2 partial pressure of above 20 kPa, the addition of Arg caused a decrease in the solubility of CO2. …”

    Signaling pathways activated by PACAP in MCF-7 breast cancer cells by Zibara, Kazem

    Published 2018
    “…In addition, PACAP increased the phosphorylation levels of STAT1, Src and Raf within seconds, confirming their involvement in early stages of PACAP signaling whereas maximal phosphorylation of AKT, ERK and p38 was reached 10 to 20 min later. Moreover, selective inhibition of Src or PI3K resulted in a significant decrease in the phosphorylation of ERK and AKT, but not p38, demonstrating that PACAP signaling follows Src/Raf/ERK and PI3K/AKT pathways. …”
