and finally find the best projection value of the sample, rank the quality of corporate water disclosure, and solve the subsequent corporate water disclosure laying the foundation for solving the problem; Finally, this paper systematically proposed enterprise water information disclosure index system, bas...
The quality function value at the tth iteration is QF(t), and the random value between 0 and 1 is rand. The current iteration and the maximum number of iterations are represented by t and T, respectively. The levy flight distribution function computed using Equation is Levy(D) (6). The ...
Seepage through distribution systems can occur during or after maintenance and renovation work (Kirmeyer, G. J., & Martel 2001). If the pressure in the pipe is very low or insufficient, this greatly increases the likelihood of backflow contamination or leakage in the pipe. This can occur ...
In a controlled environment experiment, we studied how physiological changes in leaves during the vegetative phase regulate final grain yield of wheat crop

The water saturation distribution and direction of fluid flow in the matrix blocks were presented. In addition, the imbibition recovery curves of oil recovery versus imbibition time for different boundary conditions were presented and the effect of different factors on the rate of oil production was ...
In the present study, the concentration and distribution of metal ions in Poyang lake was successfully determined with MPT-MS/MS based on negative mode. The detection limit of the metal ions was 0.03–0.33 μg•L−1, entirely fitting on-line monitoring and detection of heavy metal ions in...
We first tested the influence of chemicals and metals on DNA yields and quality by preparing a mock sample with known microbial communities (ZymoBIOMICS) containing eight different species in various abundance. The aim was to test the accuracy of different methods in terms of microbial strain recove...
We used R statistical software (http://cran.r-project.org) to test the difference between control and treatment trees applying a two-sample t-test as well as a Tukey’s range test in combination with an ANOVA (post-hoc) for each pair of data points. For diurnal sap flow analysis, we...
