El desarrollo de la educación ambiental en las universidades tiene por objetivo la formación de valores y creencias ambientales como actitudes favorables en favor del ambiente, base de una conciencia ambiental que busca alternativas de solución a la crisis ambiental. En cumplimiento a ello, la Universidad Nacional del Centro del Perú (UNCP) incorporó asignaturas ambientales en sus planes de estudio con el fin de fortalecer la conciencia ambiental de sus estudiantes y futuros profesionales; sin embargo, se desconoce la efectividad de esta acción. Por ello, la presente tesis de investigación tiene por objetivo evaluar si la inclusión de asignaturas ambientales se relaciona con las creencias y valores ambientales. Para ello se cuantifica el número de asignaturas y se mide las creencias (Escala de Nuevo Paradigma Ecológico) y valores (Escala Cuestionario retrato de valores) ambient...

La zona alta y media de la cuenca del río Mantaro (ZAMCM) es un área clave en desarrollo económico porque se desarrollan diversas actividades antropogénicas cuyas emisiones de material particulado aún son desconocidos en todas sus características. El objetivo es evaluar las características integrales de las concentraciones, composición química elemental, fuentes y regiones generadoras del material particulado atmosférico del 2007 al 2017 con la finalidad de aportar con información a la gestión del estado del aire. Para ello se monitoreo las partículas presentes en la atmosfera PM10 y PM2.5 en 3 periodos de campaña: 1) 2007-2008, 2) 2011-2012 y 3) 2017, en un total de 9 estaciones: Vicco, Junín, Paccha, La Oroya, Huari, Jauja, Concepción, Huayao y Huancayo distribuidos a lo largo de la ZAMCM. Se analizó las variaciones estacionales de PM10 y PM2.5, caracteriza la composic...

            The effect of supplementation with mashua (Tropaeolum tuberosum) and tarwi (Lupinus mutabilis) meal on body weight gain (BWG), feed consumption, feed conversion index and nutritional composition of carcasses of Peru breed guinea pigs was evaluated. Peru. For the study, 32 4-week-old male guinea pigs (309-578 g) were randomly distributed in four treatments (T) for 40 days: T1 (integral concentrate - IC), T2 (CI + 18% tarwi), T3 (IC + 25 % mashua) and T4 (I C+ 25% mashua + 18% tarwi). Supplementation with tarwi meal (T2 and T4) improved BWG, while supplementation with mashua meal (T3) had a significant effect on carcass fat content (p<0.05). There was no effect on feed consumption and feed conversion.

Huancayo is a city located at Peruvian Central Andes and presents air pollution problems related to particulate matter (PM), especially fine fraction (PM2.5). Given the high costs of air quality monitoring network infrastructure and the need for more detailed information, the objective of the study is to evaluate the temporal variation and source zones of PM2.5 through the use of low-cost sensors installed at three sites in the city of Huancayo. PurpleAir PA-II model PMS5003 sensors were employed from August 2018 to June 2019. The dataset was subjected to statistical tests to evaluate temporal changes. Backtrajectories were calculated through the HYSPLIT model for source zone identification. The results show reasonable agreement with other reference monitoring. The importance of the use of low-cost sensors in the establishment of an air quality monitoring network in high Andean areas is ...
