En los últimos años en el Perú la gran mayoría de las empresas mineras y sus socios estratégicos, las empresas contratistas especializadas implantan un Sistema Integrado de Gestión (SIG), de Seguridad, Salud en el Trabajo, Medio Ambiente y Calidad como parte de su estrategia de gestión de riesgos para adaptarse a los cambios legislativos y proteger a su personal. Toda empresa debe contar con un sistema de gestión de seguridad y salud ocupacional, que permita el control de la seguridad de sus procesos y la protección de la salud de sus trabajadores; logrando un mayor respaldo para la empresa y contribuyendo a un mejor desempeño y mayores beneficios. La presente tesis tiene por objetivo la Implementación del Sistema Integrado de Gestión para mejorar la productividad en la empresa Extreme Services SAC - Cía. minera Antamina año 2016. Con base en las normas internacionales ISO ...

The interconnection of two power grids creates a need for new regulation policies to govern it, as many factors are involved when two markets become interconnected and the policies of each country are designed only for its internal power market. It is therefore necessary to find the best mechanism for interconnecting both markets, which will also ensure that both countries share the benefits and costs. Issues like the contribution of large hydroelectric plants with reservoirs, the implementation of unconventional renewable energy sources and the effect of both on the complementarity and integration of cross-border power markets; all are problems that have no general solution and have to be solved for each particular case.

The globally distributed necrotrophic fungus Macrophomina phaseolina is the causal agent of economically important crop diseases such as soybean charcoal rot. This fungus secretes a wide variety of proteins and metabolites that allow it to invade the plant and initiate the infection process. The role of fungi secreted proteins with hydrolytic activity in the infection process has been extensively studied; proteins without enzymatic activity could also play an important role in this process. The analysis of total proteins would allow to broaden the knowledge about this pathogen and establish more efficient strategies for its control. The objective of the present work was to evaluate three methods for the extraction of proteins secreted by M. phaseolina. The fungus was grown in potato dextrose broth (PDB) and Czapek-Dox (CZP) with and without soybean leaf supplementation. Proteins were ext...
