Hydraulic fracturing utilizes pressurized liquid typically consisting of water, proppants, and a multitude of chemical additives, in order to fracture petroliferous strata to extract natural gas and oil.In this process, a vast amount of wastewater is produced.This water is heavily contaminated, which renders it unusable outside of direct reuse, wit
The results of research on diagonal crack ornament width in a single span RC beams were presented in the article.Eurocode 2 rules do not require the direct control of shear crack width.It is assumed, that reinforcement designed to carry the transverse force is also enough to limit the crack width.Experiments were led on beams grouped into four seri
When approaching and removing a disabled satellite, the accuracy of the controller is imperative to the success of the mission because if the mission fails, more space debris can be produced due to satellite collision.To address this issue, a controller directly driven by discrete sample data points is proposed in this paper.First, the input vector

In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors.In humans, results on the effect of acute exercise on memory are inconsistent so far.Therefore, the aim of the present study was to assess the effe
