Summary: The study found that in cold seasons during the construction of mountain tunnels, the significant temperature and humidity differences between the inside and outside of the tunnel can lead to fog formation, which affects construction safety. To address this issue, it is suggested to add insulation layers to the walls, and to control the inflow air relative humidity and wall temperature to prevent fog formation.

Summary: Anthropic activities pose multiple pressures on the Amazon forests, leading to highly fragmented landscapes and increased forest edges. Different types of forest edges impact microclimate, vegetation composition, and forest structure, with pastures edges having lower humidity and higher temperatures compared to rubber plantations ones.

Summary: This paper investigates the temporal dynamic patterns of negative air ion (NAI) concentrations through long-term on-site monitoring. The study finds that NAI concentrations show a bimodal curve on a daily basis, with peaks in the early morning and afternoon, and lowest concentrations at noon. At the monthly scale, NAI concentrations are relatively high in February and August, while low in May and December. Furthermore, NAI concentrations are significantly higher in summer and autumn compared to other seasons. The study also reveals that the air quality index (AQI) is the most important factor affecting NAI concentrations, with a negative correlation observed between NAI concentrations and particulate matter and ozone levels.

Summary: This study investigates the influence of indoor environmental factors on the 24-hour toluene uptake rate of Tenax TA diffusive samplers and found that temperature, humidity, and concentration have significant effects on the uptake rate. The increase in temperature and humidity leads to a decrease in toluene uptake rate, while concentration has a positive impact.

Summary: The study investigated the effects of temperature and relative humidity on air filter loading by hygroscopic salts. It was found that testing relative humidity is a major factor, while testing temperature is a minor factor affecting the filter loading of hygroscopic particles, regardless of their state (dry/wet). The research suggests revising current filter testing standards to consider the air filter operating temperature and relative humidity.

Summary: Green walls have the potential to provide thermal comfort through passive and active systems. Active modules show a temperature decrease of 1-3 degrees Celsius when saturated wet, while passive modules provide a cooling effect of 0.5-2 degrees Celsius. The plant species studied did not show any preference, indicating that substrate moisture content plays the major role in affecting temperature and humidity variations.

Summary: This study analyzed the correlation between environmental factors and confirmed cases of COVID-19 in Victoria, Mexico, finding a strong association between COVID-19 cases and CO concentration, as well as significant correlations with particulate matter pollution (PM2.5 and PM10) exposure. Additionally, the study revealed a significant improvement in air quality during the COVID-19 outbreak period.

Summary: We propose a design of stable and transferable membrane inlaid with whispering-gallery-mode plasmon hybrid microlaser arrays for sensitive and stable thermal sensing. By integrating plasmonic gold nanorods with polymer lasing microfiber arrays that are embedded in the polydimethylsiloxane matrix, whispering-gallery-mode lasing arrays with high quality are achieved.

Summary: Extreme heat events are a significant threat to population health, especially with the amplification of climate change. Traditional statistical models do not consider potential interactions between temperature-related and air pollution predictors. Artificial intelligence methods have the potential to account for these interactions, but they have been underutilized in studying the impacts of heat on health.

Summary: This study investigates the impact of meteorological factors on COVID-19 death counts and reveals a significant negative relationship between temperature, relative humidity, and absolute humidity with the COVID-19 mortality rate. The results may help health care policymakers to develop and implement effective control measures in a timely and efficient manner.

Summary: This study examined the impact of indoor thermal conditions on EEG signals and employed logistic regression to differentiate indoor thermal comfort. Twenty male participants were recruited to record resting EEG signals under different combinations of temperature, humidity, and air velocity. Subjective questionnaires were utilized to gather individuals' perceptions of the environment and used as criteria to develop logistic regression models. The findings demonstrated that theta, beta 1, beta 2, and gamma waves were highly similar at 22°C and 25°C, as well as velocity for all EEG waves at 0.5 and 1 m/s. Additionally, 70% relative humidity was determined as the cut-off point for high humidity in the humidity test for beta 1, beta 2, and gamma waves. Moreover, regression models were developed utilizing frequency bands associated with comfort, with the overall model accurately categorizing 88.6% of the data. This research serves as a foundation for further exploration of the interconnected environment and neuronal mechanisms.

Summary: This study focuses on the development of low-cost and environmentally friendly improved evaporative cooling systems for heat stress in poultry houses. Thermodynamic analysis was carried out for the climatic conditions of Multan, Pakistan, showing that the MEC system performed relatively better than others in controlling environmental conditions and maintaining THI threshold limit with reasonable temperature and humidity indexes.

Summary: This study compared artificial neural network (ANN) and multiple linear regression (MLR) models in estimating evapotranspiration of screenhouse banana plantations. Results showed that the ANN model generally outperformed the MLR model. The study found that the choice of training month could affect the performance of the ANN model, but even with a training dataset as short as one month, the model could still provide reliable estimations.

Summary: The study found that meteorological conditions significantly affect the transmission of COVID-19 in Bangladesh, with mean temperature, relative humidity, and wind speed significantly associated with increased COVID-19 risk, while daily precipitation was negatively correlated with the risk of COVID-19 incidence. These findings provide important implications for future control and prevention measures in Bangladesh and other countries with similar climate conditions and population density.
