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. Forced-air warming and continuous core temperature monitoring with zero-heat-flux thermometry during cesarean section: a retrospective observational cohort study
Abstract Background: Over 30% of parturients undergoing spinal anesthesia for cesarean section become intraoperatively hypothermic. This study assessed the magnitude of hypothermic insult in parturients and newborns using continuous, high-resolution thermometry and evaluated the efficiency of intraoperative forced-air warming for prevention of hypothermia.

3. Water salinity and air temperature on quail production and organ characteristics
RESUMO O fornecimento de água salgada no semiárido é uma prática recorrente, visto que existe uma grande escassez de água para uso na alimentação animal. Assim, na maioria das vezes a água oferecida às aves pode apresentar sal acima do recomendado. O presente estudo teve como objetivo avaliar o desempenho produtivo e a morfometria dos órgãos de co

4. Estimation of Air Temperature Using Climate Factors in Brazilian Sugarcane Regions
Resumo Este estudo visava estimar as temperaturas mínimas e máximas mensais do ar nas regiões canavieiras do Brasil. Uma série histórica de 30 anos (1988-2018) de temperaturas máximas (Tmax) e mínimas (Tmin) do ar da plataforma da NASA/POWER foi utilizada para 62 locais que produzem cana-de-açúcar no Brasil. A regressão linear múltipla foi utiliza

5. 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

6. FUZZY LOGIC MODELING OF THE OCULAR TEMPERATURE OF CATTLE IN THERMAL STRESS CONDITIONS
ABSTRACT This study proposes a fuzzy logic model capable of predicting the ocular temperature (OT) of beef cattle by means of infrared thermography. The goal of this study is to establish a methodology for making decisions related to animal welfare. The experiment was carried out at a commercial beef production farm, located in the south of Minas Gerais stat

7. Mathematical modeling of whey foam mat drying
ABSTRACT This study aimed to fit mathematical models to whey foam drying processes in different air temperature conditions, to determine the effective diffusion coefficient and to obtain the activation energy. For foam formation, 5.0% Emustab® was added to the serum in mass and subjected to stirring in a domestic shaker for 15 min. After, it was spread onto

8. Variability in the shelf life of table grapes from same batch when exposed under different ambient air conditions
Abstract This study aimed to evaluate the effect of the variability in ambient air conditions (temperature and relative humidity) and periods of exposure on the same batch of table grapes in the first stages of the fruit supply chain (harvesting, processing and storage prior to commercialization), in order to predict their dynamic shelf life. To estimate the

11. STUDY ON THE OPTIMIZATION FOR THE SIZE OF FUEL CELL FLOW FIELD UNDER INADEQUATE AIR SUPPLY CONDITION
In this paper, the influence of the optimization for flow field size on the proton exchange membrane fuel cell (PEMFC) performance under the inadequate air supply of cathode was studied based on the three-dimensional, steady-state, and constant temperature PEMFC monomer model. Additionally, the effect of the optimization for hybrid factors, including length,

12. Base-temperature, plastochron and chia (Salvia hispanica L. - Lamiaceae) yield for different sowing times
ABSTRACT Chia is a plant whose seeds are used in cooking and is a natural source of omega-3 fatty acids, fiber and protein, as well as other important nutritional components such as antioxidants. The objective of this work was to estimate the base temperature, plastochron and chia seed yield for different sowing times in Cruz Alta, Rio Grande do Sul, Brazil.
