1. The Contribution of Meteorological Parameters and the COVID-19 Partial Lockdown on Air Quality in Rio de Janeiro, Brazil
This study evaluated the pollutant levels (NO2, SO2, CO, and O3), air quality index (AQI) and the influence of meteorological variables and coronavirus disease (COVID-19) pandemic on the air quality in Rio de Janeiro. The data set used comprises periods before (March-April, 2019) and during pandemic (March-April, 2020). According to the AQI results, on most

2. El Niño-Southern Oscillation impacts on grape yields in Santana do Livramento, Brazil: understanding and early warning of crop failure conditions
ABSTRACT El Niño-Southern Oscillation (ENSO) is an important source of year–to–year fluctuations in the whole global climate system and in the southern Brazilian climate. El Niño events affect this region, imposing unfavorable weather conditions (rainy/humid/overcast) during critical grapevine phenological stages, compromising yields in the current and

5. Radiation Balance and Partitioning of Latent and Sensible Heat Fluxes Over a Lime Orchard in Eastern Amazon
Abstract We investigate the balance of radiation and energy over a lime orchard in Eastern Amazon and how it relates to environmental conditions. We found that lime trees aged between 6 and 7 years old reflect 11.0% to 14.5% of incoming shortwave radiation, and the latent heat flux corresponds to 57.6% and 66.6% of the daily net radiation in the dry season (

6. Job precariousness: supply chain management in a waste pickers association
Resumo Waste pickers are key players within municipal solid waste management and an important link in the recycling chain. Waste pickers perform their activities in precarious conditions: they work in bad weather; run the risk of traffic accidents; come in contact with insects that transmit disease and suffer from weight overload. These conditions are aggrav

8. Suitable weather condition frequency for fungicide soybean application in Tangará da Serra, Mato Grosso, Brazil
ABSTRACT The aim of this study was to model the decendial and hourly variability of meteorological variables, namely air temperature, relative air humidity and wind speed, in the Tangará da Serra region, Mato Grosso, Brazil, to determine the best schedules for fungicide applications to soybean crops. Hourly weather data between 2004 and 2017 from the Tangar

9. Assessment of Total Attenuation and Adaptive Scheme for Quality of Service Enhancement in Tropical Weather for Satellite Networks and 5G Applications in Nigeria
Abstract The dynamic weather condition is a major concern for optimum channel utilization in recent times, especially at higher frequencies with larger bandwidth for 5G applications. Over the years, rain-induced attenuation among the hydrometeors has been linked as the major cause of signal impairment especially at the frequency, f ≥ 10 GHz. However, when

11. Lignin-modified road marking paint: weathering aging studies
Abstract The accelerated artificial aging with ultraviolet radiation, viscosity, density, no-pick-up time, flexibility, and abrasion resistance of lignin-modified road marking paint were evaluated. The addition of lignin did not cause significant changes in the physical chemistry, flexibility and no-pick-time test compared to the precursor paint. The additio
