Abstract: In this paper, we define the set (CF_(T_n,(n))(X_n))^{A^s} of all n-ary C-formulas on the partial algebraic system A^s=(A;(f^A_i)_i in I,r^A) of type (T_n,(n)) and define the operation R^{n,A} on the set( (W^C_{T_n}(X_n))^{A^s}U(CF_(T_n,(n))(X_n))^{A^s}. After this definition we have a unitary Menger algebra ( ( (W [...] Read more.

Abstract: The study of analytical patterns in the evolution of individual components of the oceanosphere was laid down in oceanology by the programme of the first oceanological expedition aboard the Challenger at the end of the 19th century. The national geographical school solves problems that are relevant both in physical geography [...] Read more.

Abstract: In this study, we examined evaluation methods based on hydraulic flux measured with the permeability-testing device GWT-4000 and its relationship with bleeding, which affects surface layer quality. We also analyzed the effects on bleeding of the permeability distribution in the height direction of a sample. The results show [...] Read more.

Abstract: Glass fiber-reinforced mortars (GRM) are widely used exterior material in construction. However, their flexural strength decreases owing to the deterioration of glass fibers in alkali environment, which can be attributed to the formation of Ca(OH)2. On the other hand, Geopolymers (GP) that do not use cement as a binder can [...] Read more.

Abstract: In this study, we conducted electrical resistivity tests and small-diameter drilling tests on mortar surface layers using water-cement ratio and unit water content as experimental factors, and we investigated the effect of electrical resistivity on the drilling speed. Results showed that water content had a considerable eff [...] Read more.

Abstract: In order to solve the problem that China's agricultural trade prospects in the "the Belt and Road economic belt" are unclear, this paper proposes a prediction system based on the stochastic frontier gravity model.This process examines the current situation of agricultural industry and the change of economic structure in Chi [...] Read more.

Abstract: In recent decades, social movements around the world have worked to advance social and political causes, including struggles against tyranny, governmental corruption, police brutality, struggles for changing gender norms, reduce economic inequality and increase awareness of the climate crisis. Digital tools have helped youn [...] Read more.

Abstract: Objective: This study aims to obtain the best equation model for QSAR which can be used as a gout drug. Quantitative analysis of the structure-activity relationship of 5-aryledene-N,N'-dimethylbarbituric acid derivatives has been carried out as a drug for gout.
Methods: QSAR analysis was performed using [...] Read more.

Abstract: Sustainable mobility is a major global challenge that affects the future of humanity and the planet. Economic growth depends on high levels of motorization, which produce greenhouse gases and other pollutants from vehicle emissions. These emissions harm the environment and human health. To address this challenge, we need to [...] Read more.
