    Rapid Identification and Simultaneous Quantification of Aristolochic Acids by HPLC-DAD and Confirmations by MS in Aristolochia chilensis Using a Limited Biomass by Michael Araya, Samantha García, Marcia González-Teuber

    Published 2018-01-01
    “…The HPLC conditions used a single mobile phase acetonitrile : water (1 : 1) acidified with 0.1% acetic acid and an isocratic elution to 1 mL·min−1. The column InertSustain C18 250 × 4.6 mm and 3 µm was used, the injection volume was 20 µL, and the time of run was reduced to 15 min. …”

    Analysis of Dust Reduction Characteristics of Multistage Tandem Dust Removal System by Jiajun Zhang, Dong Liang, Yuanwen Cao

    Published 2023-01-01
    “…As a result, an antiventuri cyclone dust collector with a scrambling column was designed. When the inlet air speed is 6 m/s, the dust removal efficiency of the improved device is 97.0%, which is 5.1% higher than that of the original device, and when the inlet air speed is 8 m/s, the dust removal efficiency of the improved device is 97.3%, which is 4.16% higher than that of the original device. …”

    A Simple and Improved HPLC-PDA Method for Simultaneous Estimation of Fexofenadine and Pseudoephedrine in Extended Release Tablets by Response Surface Methodology by Ruhul Kayesh, A. S. M. Moniruzzaman Sarker, Md. Zakir Sultan, Md. Sarowar Jahan

    Published 2017-01-01
    “…Separation was achieved on double end-capped C18 column (250 mm × 4 mm, 5 μm). In this experiment, two components of mobile phase, namely, acetonitrile (% v/v) and methanol (% v/v), were the factors whereas retention and resolution of the chromatographic peaks were the responses. …”

    pyScrew4Mobility: Modul Python untuk Penentuan Mobilitas Manipulator Paralel Berbasis Teori Screw by Adriyan Adriyan

    Published 2020-04-01
    “…The algebra methods are applied to obtain reciprocal of a screw or a screw system and basis of a screw system using null-spaces and the row/column-spaces technique, respectively. Hence, an object-oriented python module, called a pyScrew4Mobility module, is designed to realize such implementation. …”

    The Influence of Form and Rate on the Efficacy of Matrix-Based Fertilizers to Reduce Nutrient Leaching by James A. Entry, R. E. Sojka

    Published 2009-01-01
    “…We tested the efficacy of matrix-based fertilizers (MBFs) to reduce NO3, NH4, and total phosphorus (TP) leaching compared to Osmocote 14-14-14, a commercial slow release fertilizer (SRF) in greenhouse column studies. The MBFs covered a range of inorganic N and P in compounds that are relatively loosely bound (MBF4) and more tightly bound compounds (MBF5) with A12(SO4)3⋅18H2O and/or Fe2(SO4)3⋅3H2O and with high ionic exchange compounds starch, chitosan, and lignin. …”
