TL;DR: In this article, the authors investigated the strategies for teaching and learning Spanish as a mother tongue and concluded that the use of the learning model by scheme facilitates the restructuring and generation of a new didactic sequence of the students' work.
Abstract: This research has investigated the strategies for teaching and learning Spanish as a mother tongue. It is an analysis of 45 didactic works by university students of Hispanic Language and Literature of the National Autonomous University of Nicaragua - Managua, divided between the different macro-skills: writing, oral expression, reading comprehension, grammar and literature. The main results show that the use of the learning model by scheme facilitates the restructuring and generation of a new didactic sequence of the students' work. It is concluded that the model of learning by scheme strengthens the didactic and research competence of the students.

TL;DR: In el ordenamiento juridico-constitucional nicaraguense, el recurso de amparo has a doble naturaleza juridica: es un mecanismo de proteccion de derechos and garantias constitucionales, and eventualmente, permite el control de normas in casesos concretos as discussed by the authors.
Abstract: El presente articulo tiene como objeto de estudio el recurso de amparo en Nicaragua. Se parte de los rasgos generales de la justicia constitucional nicaraguense a traves de los distintos mecanismos de control de constitucionalidad y los organos de control de esta y se profundiza en la naturaleza juridica del recurso de amparo en Nicaragua, asi como su funcion y objeto. De igual forma, se estudia el procedimiento del recurso de amparo que abarca los sujetos legitimados, las etapas del recurso y concluye con la sentencia y sus efectos. En el ordenamiento juridico–constitucional nicaraguense el recurso de amparo tiene una doble naturaleza juridica: es un mecanismo de proteccion de derechos y garantias constitucionales y eventualmente, permite el control de normas en casos concretos.

TL;DR: In the teaching work, it is necessary to consider an accurate didactic planning as one of the essential aspects that can assure an appropriate mathematical teaching in different educational subsystems as discussed by the authors.
Abstract: In the teaching work, it is necessary to consider an accurate didactic planning as one of the essential aspects that can assure an appropriate mathematical teaching in the different educational subsystems. Currently, it is incoherent to even think that learning abilities can be achieve in the students, without having structured the work that will be carried out in the different class sessions. Therefore, the didactic units allow us to create a complete teaching-learning process, innovative and with pedagogical actions that seeks to reach the mathematical skills in students. If we take into account students' interests, their motivations, the contents to be addressed; the activities and materials to be used, the use of the existing technological resources; the learning regulation, the constant evaluation process, the abilities to be developed in students, and a teaching role that breaks the existing conformist and traditional scheme, then we will have as result an assisted teaching of mathematics. This mean that we will have students who use in their own context the mathematical learnings they have achieved and teachers who are systematically investigating the best way to teach through action and research.

TL;DR: In this paper, Scheffe et al. evaluated the adhesion of three sistemas adhesivos: Single Bond 2, One Step Plus, and PQ1, in a dentina intracameral with NaOCl 3% and NaOCL 3% + EDTA 17% combinados; por medio de the prueba microtensil.
Abstract: El objetivo de esta investigacion fue, evaluar la fuerza de adhesion de tres sistemas adhesivos: Single Bond 2, One Step plus y PQ1, en dentina intracameral previamente irrigada con NaOCl 3% y NaOCl 3% + EDTA 17% combinados; por medio de la prueba microtensil. Se seleccionaron 90 terceros molares humanos libres de caries, los cuales se dividieron en tres grupos (N=30) dependiendo del irrigantes endodontico; GI: Agua destilada (control), GII: NaOCl 3% y GIII: NaOCl 3% + EDTA 17%. Cada grupo se subdividio en tres subgrupos dependiendo del sistema adhesivo a utilizar. A los dientes se les coloco resina compuesta Z100 e inmediatamente despues se seccionaron en sentido trasversal hasta obtener un especimen por diente de la interface adhesiva, con un area aproximada de 1 mm * 1 mm. Cada especimen fue sometido a la prueba adhesiva microtensil, en una maquina de ensayos universal (Tinius Olsen H10K-S). Los valores de la fuerza adhesiva fueron expresados en MPa y analizados con un analisis de varianza (ANOVA) de dos vias, a traves de la prueba estadistica Scheffe utilizando el programa estadistico KaleidaGraph 4.0. a 0.05 grados de significancia. Dentro de las condiciones en las que se realizo el presente estudio se pudo concluir que la fuerza de adhesion microtensil de los adhesivos Single Bond 2, One Step Plus y PQ1 fueron estadisticamente iguales entre si para el mismo irrigante y cuando se trata la dentina intracameral con irrigantes endodonticos como el NaOCl 3% o NaOCl 3% + EDTA 17% en combinacion; la fuerza de adhesion microtensil de los adhesivos Single Bond 2, One Step Plus y PQ1 disminuye.

TL;DR: A proficiency test was carried out with the participation of 24 environmental laboratories, 12 Nicaraguan and 12 Costa Rican, to give continuity to the MIFIC-PTB cooperation project “Improvement of Services that Ensure Quality for the Water Sector of Nicaragua” as discussed by the authors.
Abstract: espanolSe realizo un ensayo de aptitud con la participacion de 24 laboratorios ambientales, 12 nicaraguenses y 12 costarricenses, para darle continuidad al proyecto cooperacion MIFIC-PTB “Mejora de los Servicios que Aseguran la Calidad para el Sector Agua de Nicaragua”. El proposito fue evaluar la competencia analitica de los laboratorios participantes y demostrar la capacidad tecnica y cientifica del CIRA/UNAN al organizar y desarrollar un Ensayo de aptitud. Se elaboraron dos lotes de muestras con sus respectivos ensayos de homogeneidad y de estabilidad de acuerdo a la ISO 13528:2016, uno para la medicion de conductividad electrica y otro para determinar dureza total, dureza calcica, calcio y magnesio en solucion acuosa. A partir de estos resultados, se establecio a cada magnitud un “valor asignado”, el estadistico utilizado para la evaluacion fue el “z- puntaje”, que mide el desempeno relativo al sesgo. Las mediciones de dureza total y calcio presentaron un excelente desempeno, en cambio las mediciones de conductividad electrica, dureza calcica y magnesio presentaron un buen desempeno. El CIRAUNAN-Managua, demostro su competencia tecnica y cientifica al desarrollar el presente ensayo de aptitud, posicionandolo en ventaja para llegar a ser laboratorio proveedor de ensayos de aptitud en Nicaragua en un mediano plazo. EnglishA proficiency test was carried out with the participation of 24 environmental laboratories, 12 Nicaraguan and 12 Costa Rican, to give continuity to the MIFIC-PTB cooperation project “Improvement of Services That Ensure Quality for the Water Sector of Nicaragua”. The purpose was to evaluate the analytical competence of participating laboratories and to demonstrate the technical and scientific capacity of CIRA/UNAN by organizing and developing a proficiency test. Two batches of samples were prepared with their respective homogeneity and stability tests according to ISO 13528:2016, one for the measurement of electrical conductivity and the other for determining total hardness, calcium hardness, calcium, and magnesium in aqueous solution. From these results, each magnitude was set an “assigned value”, the statistic used for the evaluation was the “z-score”, which measures the performance relative to bias. Measurements of total hardness and calcium performed excellently, instead of electrical conductivity, calcium hardness, and magnesium showed a good performance. CIRAUNAN-Managua demonstrated its technical and scientific competence when developing the present proficiency testing, positioning it in advantage to become a proficiency testing provider laboratory in Nicaragua in a short time.
