A mathematical model is developed to help decision makers choose the best combination of technologies for electricity distribution and, in turn, in this way, generate a scientific tool for strategic decision making that allows an organization to meet the demands and the balance of the distribution of loads, consumption at the right time, a period, in the precise place and in the necessary quantity. The model obeys the satisfaction of the demand and minimize the cost taking into account the restrictions. The model is built in modules which facilitates changes and the possibility of adding new functions. The implementation of the model is done using GAMS (General Algebraic Modeling System), designed to model optimization problems with solvers based on the state of the art. This meets their expectations and works as intended, that is, the demand is satisfied with a minimized cost. The future development of the model should focus on its improvement so that it takes into account other factors increasing its complexity. Keywords: Model, Mathematical model, electrical efficiency, Distribution of electric charge.

The pavements must comply with an appropriate useful life time according to their structural design, providing safety and comfort to the users who pass through this infrastructure. In this sense, the objective of this research lies in proposing a micro-surfacing type asphalt mix design with additives based on technical specifications that improve the rolling surface. For this, in the first instance, the bibliographic base of research related to micro-surfacing is analyzed. On the other hand, the physical and mechanical properties of the materials used in the asphalt mix are determined and the optimal percentages of additives used in the asphalt mix are established. The methodology applied in this design is the one stated in the Manual of the North American Institute of Asphalt DESIGN METHODS FOR ASPHALT CONCRETE AND OTHER TYPES OF HOT MIXTURES, recommended and accepted by the Ministry of Transportation and Public Works of Ecuador. The properties of the materials, their dosage and tolerable ranges have been determined according to the requirements. Keywords: Pavements, Asphalt Mix, Micro-pavements.

Body expression as one of the learning areas of initial education considered fundamental for the development and development of children, was carried out in virtuality in the time of the pandemic, facing the little physical activity of certain students and their resistance to participate in the programmed activities, as a fundamental element was the lack of knowledge of the parents to carry the activities out due of their ignorance about the methodology to be followed in the development of body expressive skills, for these reasons the present proposal was given to elaborate a manual of activities for the development of body expression in students of initial two of the Basic Education School "Mariana Cobos de Robles" in Portoviejo city.  This article approached the criteria of several authors with the purpose of supporting the importance of the development of body expression, using for its development the mixed approach, with empirical, theoretical-logical methods, descriptive statistics and using interview and observation as techniques, resulting in the need to strengthen the mentioned skills at home where parents must be guided with a respective manual of activities for children in stages of 3 and 4 years. Keywords: corporal expression, initial education, activities manual.

This academic essay compiles the pedagogical experience on the teaching of writing from the competency curriculum of the Lengua y Literatura Hispánicas Career. The strategic element in this process is the integration of the curricular components, which allows the interdisciplinarity of knowledge, with an emphasis on procedural and attitudinal knowledge that students must develop in order to achieve the citizen and scientific-technical competencies that society demands from students education professionals. In this sense, the student of the first levels of Lengua y Literatura Hispánicas begins their learning process in terms of the acquisition of communication skills, including written communication, this skill is worked through an integrated, active, creative and constructive process.  

Literature (understood as art with a measurable value from other cross-sectional activities starting from it) has been taken for a long time, in certain critical positions, such as a symbolic-representative magnification written from the past, social events, natural, philosophical, and so on. In the field of higher education, there are certain essential guidelines for learning and teaching from literature that shape the pedagogical character of the training in this area of knowledge, of course, the degree in/for the field of teaching is configured. Therefore, this text aims to bring these guidelines closer together and to reflect on the effectiveness and the way they are treated from the pedagogical field, taking into account the transdisciplinary educational scope of the literature career for the benefit of an integral student training in values, both in the Ecuadorian and Latin American case.  

Starting from a comparative approach, the following interpretive work analyzes the poetry of Ernesto Mejía Sánchez and his aesthetic links with three poets of European Romanticism: Novalis, Charles Baudelaire and Stéphane Mallarmé. Novalis' relationship with the Nicaraguan is reflected in the conception of poetry as magic, ritual and enchantment, as well as in the importance that Mejía Sánchez attributes to the nocturnal. With Charles Baudelaire the communicating vessel is the game of correspondences and analogy. From Mallarmé, our poet will take the vision of the poem as an artistic object, that is, free from the bonds of meaning, both poets imagine the poem as an exercise of silence and emptiness.  

This work focuses on the lexical abbreviation and takes as an example of analysis two forms (suba and baja). The description gives an account of where these reduced forms are used and how often they appear in each of the countries. It also studies the type of nouns that appear in the recorded examples, and if the plural forms (subas and bajas) are equally used. Likewise, the analogy process is analyzed and a description of how these abbreviated nominalizations have been formed is offered, and since when they have been recorded in the history of the Spanish language. Finally, it shows that the two cases studied are part of the general phenomenon of noun abbreviation in Spanish.
