El presente trabajo describe y explica de que manera los factores como la escasa experiencia social y política, el desconocimiento de las herramientas de gestión municipal y las barreras culturales limitan el desempeño de las regidoras en la función pública, a nivel de los gobiernos locales de la Provincia de Huamanga, Región Ayacucho, durante los primeros años (2011-2012) de gestión del periodo 2011-2014. Por otra parte desarrolla, los aciertos y dificultades del desempeño propiamente dicho de parte de las regidoras como representantes políticas en el interior de los gobiernos subnacionales, en el cumplimiento de sus principales funciones de representación, fiscalización y presentación de normativas y propuestas de políticas públicas, durante los dos primeros años de gestión municipal en los distritos de la provincia de Huamanga, en base a la estructura siguiente: capit...

The purpose of this study was to establish the relationship between administrative management and work performance in the Sub Regional Management of Ucayali - Contamana in the year 2023. A descriptive correlational approach was used, through a non-experimental design. The sample consisted of 127 administrative workers selected from a population of 190 employees. A questionnaire was applied to them to collect the necessary information. The results revealed that administrative management was evaluated as fair (29%) and employees' work performance as average (27%). Furthermore, a positive and significant relationship was found between administrative management and job performance, supported by a correlation coefficient of r=0.861 and a significance of p=0.000. Likewise, the planning dimension shows a coefficient and significance of (r= Rho=0.773; p=0.000); Also, the organization dimension p...

El presente trabajo tiene por finalidad dar a conocer una mejora de nivel de servicio de empresas de perforación de chimeneas de ventilación para minas de socavón, las cuales cumplen una labor sumamente importante en el desempeño del cliente. El estudio se basa en la toma de información sobre la forma como se realiza el servicio y el tiempo que demora, tratando de minimizar todo tiempo de falla y mejorar las horas de producción aplicando herramientas de ingeniería industrial como son la gestión de inventario, TPM sobre todo los pilares de mantenimiento autónomo y mantenimiento planificado. Al momento de analizar los tiempos improductivos se encontró fallas de equipo y falta de control de inventario que dan como resultado horas de parada de producción lo cual perjudica la entrega de los proyectos en tiempo pactado con el cliente, para las fallas encontradas de índole mecánica...

This breeding project, initiated at the United States Potato Genebank (USPG) in collaboration with Peruvian partners Instituto Nacional de Innovacion Agraria (INIA), International Potato Center, Peru (CIP), and local farmers, sought to enhance cold hardiness and frost tolerance in native potato cultivars in Peru. The Andes and Altiplano are often affected by frost, which causes significant reduction in yield; creating varieties with superior resilience is a critical undertaking. The goal was to transfer outstanding non-acclimated cold tolerance and acclimation capacity found in wild potato species Solanum commersonii (cmm). Breeding families segregating for cold hardiness were created using (a) a somatic hybrid cmm + haploid Solanum tuberosum (tbr) (cv. Superior, US variety from Wisconsin) as male and (b) seven cultivars native to Peru of the species S. tuberosum sbsp. andigenum (adg) as...

Crop wild relatives (CWRs) are important sources of novel genes, due to their high variability of response to biotic and abiotic stresses, which can be invaluable for crop genetic improvement programs. Recent studies have shown that CWRs are threatened by several factors, including changes in land-use and climate change. A large proportion of CWRs are underrepresented in genebanks, making it necessary to take action to ensure their long-term ex situ conservation. With this aim, 18 targeted collecting trips were conducted during 2017/2018 in the center of origin of potato (Solanum tuberosum L.), targeting 17 diverse ecological regions of Peru. This was the first comprehensive wild potato collection in Peru in at least 20 years and encompassed most of the unique habitats of potato CWRs in the country. A total of 322 wild potato accessions were collected as seed, tubers, and whole plants fo...
