The present study is intended to get to know thelevels of perimeter diurnal environmental noise of fourhospitals in the city of Lima. The measurement mode usedat each hospital was A-weighting, with an integration timeof five minutes per recording. It was measured in the FASTmode with calibrations made at the beginning and end ofthe measurement day. Statistical analysis consisted of themean comparison T test which was applied at all the hospi-tals considered in the study. At the four hospitals, at all thehours of measurement and both on working days and non-working days (Sunday), LAeq mean values are higher than83 dBA. On working days, two periods of maximum noisefrom 08:00 to 10:00 in the morning and from 17:00 to 19:00in the afternoon coincide with the start and end of workinghours. The perimeter diurnal environmental noise levelsdetermined at the vicinity of four hospitals show higherv...

The city of Lima presents a very uneven development of bicycle lanes in all its districts, where the district of Miraflores stands out as the one with the greatest development. The present work aimed to evaluate the bicycle infrastructure in this district. The applied methodology combined the land survey, with virtual surveys and processing of satellite images in a GIS environment. This evaluation was made based on the main aspects related to cycle-inclusivity, security, cohe-rence, direction, and infrastructure of the cycle. Among the main results, they stand out that the safety levels are low, which allows to infer that a greater number of physically segregated bike lanes should be promoted. The coherence is very poor in managing to connect several points of origin and destination, with numerous crossings. Although the main routes are fairly direct, the poor location of the bicycle par...

The main characteristics of photovoltaic (PV) energy and its current development in Latin American and Caribbean countries (LAC); its impact on the electrification of homes, health institutions, and schools in isolated or difficult-to-access communities; and, the advantages thereof are presented and discussed by replacing the use of traditional fuels such as firewood and kerosene in order to improve inhabitants ’health as well as reducing CO2 emissions. Countries like Nicaragua, Peru, Brazil, Argentina, and Chile stand out for their growing PV energy development in the region. A case study of the electrification process by PV systems shows very positive changes are manifested in terms of improving the quality of life of the inhabitants, and especially their physical and mental health state. In addition, CO2 emission reductions from electrifying 216 houses in the nine communities reach ...
