Summary: The study conducted fire experiments of wall-attached fires with different aspect ratios and investigated the effect of the sidewall on flame height and radiant heat flux. Experimental results were consistent with predictions by an existing model, validating the reliability of the setup. A new model based on flame height increase and thermal radiation from the sidewall was developed to estimate radiant heat flux, with prediction error less than 15%.

Summary: More than 60,000 firefighters were injured in the U.S. in 2019, and inadequate protection by bunker gear could be a major reason. The degradation of bunker gear fabric during thermal exposure and the impact of moisture on its performance have been identified. Evaluating the tensile strength of fabrics under different heat flux and moisture levels is crucial for maintaining the overall integrity of the gear.

Summary: This study investigates the impact of fuel initial velocity and nozzle-wall spacing on the temperature distribution of a horizontal jet flame impinging a wall. A new dimensionless number is proposed to determine the maximum rising temperature of the flame plume on the wall surface. The volume of the flame plume and the distance between the wall and the flame plume are identified as important factors that explain the trend of radiant heat flux.

Summary: Human continuous sweating plays a dual role in adjusting the thermal protective performance of firefighter clothing. The moisture management performance of materials affects the heat transfer performance under continuous sweating. High sweat rates can reduce heat transfer performance and increase the risk of skin burns.

Summary: The effect of the number of layers of the thermal liner on the thermal protection properties of thermal protective clothing has been studied. The experiment shows that the protection time increases with the increase in the number of layers, and decreases with increased heat flux. The effect of the number of layers is more prominent at a lower level of heat flux.

Summary: This paper proposes novel modifications to existing solid flame and point source models to better predict the spatial contour of near-field, steady-state radiant heat flux from large circular pool fires. The modified models take into account partial smoke obscuration of the flames and accurately calculate the emissive power of the visible flame layer. The results demonstrate that the proposed models can effectively predict the spatial contour and peak value of radiant heat flux on nearby targets with low computational effort.

Summary: This study investigates the impact of fabric deformation on both thermal protective and thermal hazardous performance. The results show that increasing tensile ratios decrease heat storage in the fabric system but increase the skin absorbed energy. Tensile ratios have a more negative effect on the thermal protective performance of single-layer fabric than double-layer fabric. Compression significantly improves heat discharge to the skin. Regression models demonstrate that fabric deformation has a greater effect on thermal hazardous performance, particularly compression.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
