Polyethylene terephthalate (PET) is a widely used material in container manufacturing, particularly in bottle production. It is characterized by its low cost and widespread availability. However, its improper disposal has significantly exacerbated global plastic pollution. For instance, less than 50% of plastic bottles are recycled. Moreover, studies indicate that this issue has led to a significant accumulation of plastic waste in the oceans, which continues to grow annually and could be considered floating islands of debris. This study proposes replacing PET with polylactic acid (PLA), a biodegradable and biocompatible polymer with suitable properties for bottle production. PLA also has a shorter decomposition time compared to PET, contributing to the reduction of carbon footprint and greenhouse gas emissions. The research methodology included a diagnostic phase to define objectives, i...

This research aimed to compare the internalizing (anxiety and depression) and externalizing (hyperactivity) symptoms of Caraquenian children based on the level of food insecurity reported by their parents. A simple retrospective design was proposed with a sample of 200 children, aged between eight and twelve, and their representatives, in charge of reporting the food insecurity levels in their homes and the symptoms of perceived hyperactivity in their children. For the analysis of results, the non-parametric Mann-Whitney´s U technique was used to compare anxiety, depressive and hyperactive symptoms based on high and low levels of food insecurity. Results suggest moderate conditions of food insecurity in the households. Furthermore, regarding the set of internalizing symptoms evaluated, it was found that households with greater food insecurity tend to have children with greater manifesta...

The objective of this work was to compare different approaches that allow a better characterization of the environmental quality using benthic macroinvertebrates as indicators in rivers of the southwestern highlands. The study was developed with data from the hydrobiology monitoring of the Quellaveco Project between the years 2013-2015, with which we obtained quality indices (ABI, EPT, IMEERA and SVAP), community structure indices (Shannon, Simpson, N1 of the Hill and Pielou series) and functional diversity indices (richness, diversity, dissimilarity and functional equity, and Rao’s Q). The results of the multivariate analyzes showed that the rates of functional diversity, Simpson’s index and IMEERA have significant representativeness in the study units. We concluded that functional diversity indices can be alternative to traditional and environmental quality indices, in addition to ...

El problema de distribución de planta se puede generalizar como un caso de optimización combinatoria intensamente estudiado y por lo tanto su naturaleza es un NP-difícil. El núcleo del problema originalmente introducido como el Planeamiento Sistemático de la Distribución, un procedimiento multi-criterio y relativamente simple, se ha extendido a contextos mayores, pasando por la formulación como un modelo matemático según la naturaleza de los talleres de trabajo. Dada la complejidad computacional de los cálculos se han desarrollado heurísticas, metaheurísticas y otros para obtener soluciones aproximadas. El objetivo de éste estudio es analizar investigaciones recientes en los problemas de distribución de planta dentro del contexto industrial en orden de clasificar y comparar la representación del problema, métodos de solución, restricciones y la función objetivo usado. E...

Semiconductor-insulator interfaces play an important role in the performance of many different electronic and optoelectronic devices such as transistors, LEDs, lasers and solar cells. Particularly, the recombination of photo-generated charge carriers at interfaces in crystalline silicon solar cells causes a dramatic efficiency reduction. Therefore, during the fabrication process, the crystalline silicon must be subjected to prior superficial passivation; typically through an insulating layer such as SiO2, SiNx or AlOx. The function of this passivating layer is to reduce electrical recombination losses in interfacial defect states originating from dangling bonds. The associated passivation parameters are, on the one hand, stable charges within the insulating layer (Qox) that by repelling a certain type of charge carrier from the crystalline silicon surface, reduces its recombination effec...

Esta investigación tiene como objetivo demostrar que resulta necesario extender los alcances de la cosa juzgada en la legislación peruana, debido a que la actual regulación puede conllevar al inicio de procesos innecesarios que vulneran los principios de economía y celeridad procesal, así como el derecho a la tutela jurisdiccional efectiva. En el transcurso de esta investigación, se ha determinado que la regulación de la cosa juzgada en el ordenamiento jurídico peruano, si bien es cierto cumple con una función negativa, la cual impide que se vuelvan a tramitar procesos sobre un mismo caso dos veces, esta función no está del todo cubierta debido a la forma en que se ha legislado la cosa juzgada en nuestro marco legal, el cual permite que se pueda ventilar una misma cuestión en procesos distintos, esto nos llevó al siguiente enunciado: ¿De qué manera resulta necesario regula...
