Abstract: Animated pedagogical agents (APAs) are increasingly developed in the educational field to motivate students’ learning and improve learning outcomes. However, dissociation between teachers and the courseware engineers during APA development has been a known limitation. Therefore, a student-centered approach by a three-party [...] Read more.

Abstract: The article is devoted to the study of the sources of formation of the doctrine of international circular law. Circular law is defined as a set of legal norms that define and regulate social relations in the field of a circular economy. The authors insist that circular law as a branch of international public law is now only [...] Read more.

Abstract: Sorption of heavy metal ions by different pectin-rich materials such as waste citrus peels and pectin extracts is emerging as a low-cost and double-headed solution technique for metallic contaminant removal and biomass solid waste management. Heavy metal ions present in drinking water and foods have remained a challenge, as [...] Read more.

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.
