The concentrations of total phosphorus (TP), total nitrogen (TN), chemical oxygen demand (COD) in the surface water decreased from upstream to downstream, and the amounts were diluted by flooding from 0.08 to 0.05 mg·L−1for TP, from 0.06 to 0.02 mg·L−1for TN and from 132 to 2...
K Linde,WB Jonas,D Melchart,F Worku,H Wagner,F Eitel 摘要: 1. We conducted an overview and quantitative meta-analysis of all experimental literature on the protective effects of serial agitated dilutions (SADs) of toxin preparations. 2. Articles were systematically collected and evaluated for ...
The RiteFlex Foamer or Sprayer by Hydro Systems offers a low-cost, portable means of foaming and spraying chemicals over large areas.
Abstract The atomic-levelAItopological indices and the modifiedXu(mXu) index were utilized for quantitative structure–property relationship (QSPR) modeling of the infinite dilution activity coefficients of 108 oxo compounds in water at 298.15 K. Stepwise multiple linear regression (SMLR) analysis using...
The results obtained from the Plackett–Burman (PB) design are summarized in the Pareto chart (Figure 1,Table S2), indicating that the extraction time and extraction temperature were the most significant variables. Other factors such as sample weight, equilibration time, desorption temperature, and ...
