This research study aims to describe primary school sixth grade students’ perceptions of people with disabilities or with low functional performance. The EPADI-1 scale is applied by using intentional and non-probabilistic sampling of 429 students (220 men and 209 women) from the Region of Murcia (Spain). The results obtained through an exploratory factor analysis show the presence of five factors that answer the objectives of the present study. It is concluded that inclusion processes continue to be insufficient since student perceptions still keep a stereotypical view that leads to the creation of situations that exclude people with disabilities or that exclude peers with low functional performance.

Este estudio aplica un modelo de referencia que implementa la minería de datos como parte de un entorno de inteligencia de negocios para analizar la operación de un turbogenerador hidráulico. Los datos analizados provienen del sistema de control y adquisición de datos de una central hidroeléctrica. Se genera un modelo utilizando análisis de componentes principales. Luego, se evalúa el modelo con nuevas observaciones utilizando los gráficos de control estadístico multivariante: cuadrado del error de predicción y T 2 de Hotelling y finalmente se implementa el análisis conectando las tablas generadas con una herramienta convencional de inteligencia de negocios. El modelo se prueba en cinco muestras correspondientes a periodos previos a una parada del turbogenerador. Se concluye que el modelo de referencia utilizado

The primary objective of this study is to propose the use of nonlinear functions to find a feasible interior point in a region defined by the constraints of linear programming problems with the advantage of not having to use slack or surplus variables. The feasible region of linear programming problems is defined by convex sets named polyhedra that have the form Ax ≤ b and that can be bounded or unbounded. Finding an interior point (even extreme or frontier point) is not a trivial issue but is a necessary condition to initialize algorithms for solving a linear programming problem. To achieve this, unrestricted nonlinear penalty functions are applied and optimized. As a result, it is demonstrated that the optimal solution point corresponds to an interior point of the original polyhedron. It is concluded that the proposed algorithmic procedure possesses features that provide advantages for solving linear programming problems.

This study analyzed the effectiveness of banana and plantain ( Musa paradisiaca L.) as coagulants-flocculants in the treatment of raw water from the Guatapurí River (Cesar region, Colombia). The experimental design was completely randomized. Coagulating solutions with banana and plantain as organic solute were evaluated to treat raw water with different initial turbidity, analyzing their effect on the elimination of dissolved solids that provide turbidity, electrical conductivity and alkalinity. The results showed a significant turbidity removal up to 86.8% (banana) and 84.1% (plantain) when applying 10 ppm of coagulant for an initial turbidity of 250 NTU. When applying doses of 5, 20, and 75 ppm in water with an initial turbidity of 576 NTU, a significant elimination of turbidity was achieved (banana = 99.3, 98.5 and 98.5%; plantain = 99.3, 98.3 and 98.4%). It is concluded that the coagulating solutions with plantain and banana solutes allowed to eliminate the turbidity of the raw water of the Guatapurí river.
