Metal mining is one of the economic pillars of the Peruvian economy. Peru is the main producer of gold, zinc, lead, and tin in Latin America and the second largest producer of copper, silver, and zinc worldwide. Despite its economic importance, mining has also left a plethora of Mining Environmental Liabilities (MEL) whose inadequate waste management represents a risk for both the environment and human health and is a common trigger of social problems. The Cajamarca región is the second región in Peru in terms of the number of MEL sites with the majority of them located in the Hualgayoc district. The goal of the PhD project is the assessment of the environmental impact of MEL in the Peruvian Andes using as an example two post-mining sites in the Hualgayoc district. This evaluation includes the study of soils and native plant species in terms of their metal accumulation potential and th...

The report addresses the management of parallel processes and synchronization in concurrent systems, highlighting common problems in accessing shared resources that affect efficiency and stability. It also highlights the need to optimize the management of large volumes of data and improve academic cooperation to develop advanced solutions.The objective of the study is to identify and analyze synchronization strategies that optimize parallel processes, evaluating their effectiveness in different scenarios and offering recommendations based on recent literature. A systematic review was conducted using the PRISMA methodology, selecting relevant articles published in the last five years and formulating key questions to guide the analysis. The results highlight that non-blocking strategies are more effective for managing shared resources, and techniques such as the use of mutex and actor mode...

Peruvian film production has witnessed a multiplicity of proposals and new voices since the turning of the century, but the academic production of Film Studies continues to lack a comprehensive review of what is being studied, who is doing the research, where it is being conducted, and where these works can be read. This paper aimed to identify the main characteristics of the field of Film Studies in Peru between 2016 and 2023. Using a quantitative approach, a systematic literature review was conducted based on the PRISMA 2020 protocol, with Scopus and Web of Science databases as references. The data of the registers was processed through bibliometric indicators. The final sample consisted of 46 records that met the selection criteria. The results point to a considerable increase in film studies since the mid-2010s, as well as emerging research trends inspired by Humanities such as aesth...

En los últimos años los índices de aceptación y confianza de la población en su PNP ha disminuido del 21% en el 2022, al 19% en el 2023, paralelo a ello se ha evidenciado, tal como lo demuestran estudios realizados, que en los últimos seis años, se ha pasado al retiro por medida disciplinaria a 22,837 suboficiales de los cuales más de la mitad corresponde al grado de suboficial de tercera, por la comisión de delitos como secuestro, extorsión, violencia familiar, venta de armas, corrupción entre otros y, faltas muy graves que fueron sancionados con la expulsión del cuerpo policial. Algunos estudios apuntan a la deficiente formación del elemento policial, otros a una mala selección. Se ha identificado que el problema deriva de la reducción de postulantes cada año, a los procesos de selección de los nuevos integrantes del cuerpo policial, habiéndose detectado que cada año...

In this research it is to select and find the main dimensions of a dryer for organic fertilizer, produced by the company BIOFERT SAC, from a Lagrangian perspective developed in previous studies, which combine heat transfer and mass movement of a individual particle through the dryer. In the first part of the study, a selection process dryer develops, if it is true not only a dryer is right, will choose whichever is more suitable for the type of material to be dried, then a thermodynamic analysis develops dryer to obtain a mass flow and air properties required for drying certain amount of moist product. an algorithm that associates the physical properties of the material with the mass transfer and heat, and has as output the main dimensions of drier (such as diameter and length) is then established. the EES (Engineering Equations Solver) software is a tool widely used in the area of therm...

El arroz es el cereal más importante para más del 50% de la población mundial, sin embargo las enfermedades pueden limitar su producción. El añublo bacterial de la panícula, es una de las enfermedades con mayor vigilancia en el cultivo de arroz, debido a los cambios climáticos que exacerban su incidencia. El agente etiológico de la enfermedad, se atribuye a Burkholderia glumae y Burkholderia gladioli. El presente estudio, tuvo como objetivo seleccionar controladores biológicos contra B. glumae THT, a partir de la microbiota endofítica del cultivo de arroz. Para ello, se realizaron colectas de 7 cultivares de arroz en los departamentos de Tumbes, Piura, Amazonas y San Martín. Las muestras de arroz fueron procesadas para aislamiento de grupos funcionales asociados a control biológico (Bacillus, Pseudomonas y Burkholderia). Las cepas de bacterias endofíticas fueron seleccionada...

El objetivo de esta investigación fue determinar el efecto de la merma en el costo de producción de las planchas de caucho de la empresa RR&PF OLIVARES S.A.C en un periodo correspondiente a octubre y noviembre. Asimismo, se identificó el punto de inspección donde se genera la merma y en base a ello, se buscó determinar el valor correcto de las mermas. Por otro lado, el marco metodológico permitió llevar a cabo la recolección de información durante el proceso investigativo. Para ello, mediante el instrumento de medición utilizado que fue un modelo de cuestionario, se recogió datos e información relevante proveniente de los trabajadores que laboran en las áreas de producción y contabilidad. Posteriormente a la aplicación del instrumento, se procede al procesamiento de los datos obtenidos e interpretación de los resultados respectivos en base a los objetivos planteados. En c...

La COMPAÑÍA MINERA MMG es una empresa dedicada a actividades de exploración y explotación minera de diversos yacimientos mineros, entre los cuales se encuentra la Operación Minera Las Bambas, cuyo principal centro de operaciones se encuentra ubicado en el predio denominado Fuera bamba, ubicado en el Distrito de Challhuahuacho, Provincia de Cotabambas, Región Apurímac. La presente investigación consiste en realizar una simulación la cual se divide en dos partes una para ver los errores en cuello de botella que se puedan presentar con la intención de mejorar los tiempos de mantenimiento y volverlos óptimos, ya que se viene dando cierto tipo de problemas los cuales dificultan dar una mejor disponibilidad en los flota de camiones 797F ya que en el año pasado hubo reducciones de disponibilidad. Este proceso fue seleccionado para realizar el estudio, ya que en la actualidad se cuen...

To more economic growth, less chronic malnutrition? What factors determine the persistent association between extractive economies and prevalence of chronic malnutrition? The answer to these questions is made taking as the unit of analysis the regions in Peru from 1950 to 2010. It is considered a sample of five regions: Ancash, Cajamarca, Huancavelica extractive mining and agricultural tradition, and Lambayeque to Ica economy based on agribusiness, manufacturing and trade. The study shows, in the period, parallel processes and identify a complex range of social determinants between the continued growth and a tendency to decrease in chronic malnutrition, but with different speeds in the regions over the past decade envisioning opening an epidemiological transition in nutrition. It uses information from the INEI, ENDES, project evaluations, research reports and interviews with mothers of ...
