    Distribution Coefficients of the REEs, Sr, Y, Ba, Th, and U between α‑HIBA and AG50W-X8 Resin حسب Haoyu Li (1672648)

    منشور في 2020
    "…However, only limited REE partition data between α-HIBA and cation resins exist, which makes it challenging to develop and optimize purification techniques using this platform. Here, we report distribution coefficients (<i>K</i><sub>d</sub>) of REEs, as well as Sr, Y, Ba, Th, and U, between α-HIBA at pH = 4.50 and AG50W-X8 cation-exchange resin, obtained by batch equilibration experiments. …"

    Transcriptomics-Driven Discovery of New Meroterpenoid Rhynchospenes Involved in the Virulence of the Barley Pathogen <i>Rhynchosporium commune</i> حسب Reynaldi Darma (20713741)

    منشور في 2025
    "…Infiltration of rhynchospenes into barley leaves resulted in strong necrosis, with rhynchospene B demonstrating the highest phytotoxicity and causing necrosis at a minimum concentration of 50 ppm. Silencing <i>rhyM</i> in <i>R. commune</i> WAI453 confirmed the role of rhynchospenes as virulence factors in barley disease. …"

    Dynamic of prolactin in pregnant women during pregnancy. حسب Francois Kiemde (5369657)

    منشور في 2024
    "…Code: *: <0.05; **: <0.01; ***: <0.001; ****: <0.0001. 30μl of plasma was used to determine the concentration of prolactin in blood (ng/ml). Prolactin levels were compared between multigravidae and primigravidae at each scheduled visits as described in “Method” section and presented as box and whisker plots illustration: top, bottom and middle of box, representing 25<sup>th</sup>, 75<sup>th</sup> and 50<sup>th</sup> percentiles, respectively. …"

    Pulse Ultrasound-Based Response Enhancement of a MOX Gas Sensor حسب Yumin Yang (5737235)

    منشور في 2024
    "…Comparing the steady responses of five target gases under the pulse and continuous ultrasound, respectively, it is found that the pulse ultrasound causes a better catalysis effect, and response enhancement (RE) by the pulse ultrasound with an optimal pulse width depends on the ultrasonic strength as well as the species and concentration of the target gas. For 2 ppm methanol, the RE by the pulse ultrasound is 50%, relative to the continuous ultrasound, when the pulse width, duty ratio, and working frequency are 0.4 ms, 50%, and 110.1 kHz, respectively. …"

    Effects of Membrane Degradation due to Chlorine Exposure on the Removal of Neutral Organic Compounds by Reverse Osmosis for Potable Reuse حسب Carson Odell Lee (17810305)

    منشور في 2024
    "…Compounds that had an initial rejection between 50 and 95% had a rapid decrease in rejection during the first 230 ppm-h of chlorine exposure, whereas compounds with a new membrane rejection of >95% saw little change in rejection until chlorine exposure exceeded 2640 ppm-h. …"
