In this article, we study the use of dynamic filtration, where the shear rate is independent of the feed rate, as an interesting alternative to achieve flow and high final concentrations and reduction of energy cost from pumping. The tests were carried out in standard Rayflow filtration under similar operating conditions.

In this article, both the traditional statistical analysis and machine learning (ML) approach is used to study the behavior of irrigation water consumption with a logistic regression model. 235 households in Nam Dinh, Thai Nguyen, and Phu Tho province were surveyed. The research results show that the regression coefficients between the two approaches are quite similar.

The objective of this article is to achieve profitable capital investment in a 250 MW coal-fired thermal power plant situated in east part of Tajikistan. In this context, the article applies a mathematical model to estimate the quantitative advantages of coal alternatives. The cost analysis of the plant was carried out on the basis of total capital investment, operating cost (i.e. coal feedstock, maintenance and labour, and cost of pumping power) and revenue.

Rice is commonly grown by transplanting one month-old seedlings into puddled and continuously flooded soil which leads to higher losses of water through puddling, surface evaporation and percolation. Excessive pumping of water for puddling causes problems of declining water table and poor quality water for irrigation.
