Esta Tesis se enfoca en los entrenamientos de tiro de 300 metros con francotiradores. Actualmente, se dispone de dispositivos para estimar la ubicación del impacto de un proyectil en un blanco de tiro, optimizando así el tiempo en los entrenamientos libres. Sin embargo, estos dispositivos no poseen una precisión y exactitud óptimas, debido a que su diseño está basado en un modelamiento ideal, utilizando un valor constante de 343 m/s para la velocidad del sonido, lo cual es inexacto. Según estudios realizados, la velocidad del sonido depende principalmente de variables medioambientales como la temperatura y la humedad relativa. Por ello, en esta Tesis se realizó el modelamiento de un sistema de detección de impacto de proyectiles basado en el análisis de datos, utilizando los métodos de modelamiento RCAPE (Regresion Causal Asociativa Ponderada Exponencialmente), regresión back...

Research in academic literacy has shown that scaffolding improves the reading of disciplinary texts. Included among the considered variables is the lexica. A robust vocabulary will result in better reading performance. To verify this, a semantic priming task and a reading comprehension test were applied to 31 first-year pedagogy students to establish whether there is a correlation between lexical processing and reading. The main findings indicate the establishment of weak semantic relations and normal reading performance. It is concluded that better reading performance is associated with slower lexical processing, which would suggest that readers engage in strategic operations to address comprehension tasks. This will allow for the formulation of scaffolding actions that highlight the importance of mastering the disciplinary vocabulary in order to safeguard an adequate reading task.

Electoral processes are one of the most important pillars of democracy. Transparent, fair and representative elections are the basis of the Western democracies. However, holding electoral processes does not necessarily guarantee the establishment and exercise of the democracy. Elections based on intimidation, threats, insecurity, fear, violence, harassment, fraud, vote buying, abuse, manipulation and exploitation of vulnerable conditions are threats to democracy and an expression of the exercise of corruption. Latin America in recent years has been characterized by adopting democratic governments. In recent decades, almost all countries in the region have managed to overthrow authoritarian, military and dictatorial governments. However, the democratic exercise of citizens in local, regional and national elections is often questioned due to the lack of integrity and transparency of the pr...

Our location in the world makes us a country with a high seismic risk. Taking into account that the information produced during a seismic event is of vital importance for the study carried out by seismology, it is necessary to use the appropriate type of instrumentation to record these data. Currently, electronics provides the necessary technology for the study of phenomena of this type. The design and construction of a Digital Accelerograph will allow us to carry out a detailed study of a seismic movement and the effect caused on the structure of buildings. Finally, we can say that the construction of an instrument of this type at a low cost will allow repowering and increasing the CISMID accelerographic network and, in general, improve the knowledge of seismic phenomena at the national level.

The aim of this study was to extract collagen from the waste produced in the processing of anchovies (canned and surimi). To this end, non-collagenous proteins was solubilized with a solution of 0,1N sodium hydroxide and neutralized with successive washes with water (pH close to neutral). Then, the residues were decalcified with a EDTA 0,5M solution; degreased with butanol 10% and finally the collagen protein were solubilized with acetic acid 0,5M and precipitated with sodium chloride 2,6M. Collagen precipitated was dialyzed and lyophilized. The hydroxyproline content (Hip) were quantified in waste and lyophilized collagen, getting the values of 6,5 and 52,9 mg of hydroxyproline/g sample, respectively. The solubility of lyophilized collagen decreased about 40% at a concentration of 12% NaCl. Gel electrophoresis showed a strong band of approximately 110 kDa molecular weight that correspon...

«Conformidad» is a very old institution in the Spanish criminal procedure system, since it dates back to the 19th century. In recent decades it has experienced a notable increase in its application as a negotiated criminal justice mechanism, as a result of several modifications in the Law of Criminal Procedure that have sought to introduce more space for negotiation in said figure and encourage its use. However, as an unwanted effect, such modifications have made the already convoluted regulation of said institute more complex, which makes it difficult to understand its physiognomy. This paper examines the current state of «conformidad» in the Spanish Criminal Procedure Law. Its scope of application, its requirements, its content, its processing and its effects are reviewed in the ordinary procedure, in the abbreviated procedure and in the fast procedure. A critical analysis of «con...
