Spatial distribution and migration law of respirable dust in fully mechanized mining face
For the problem that the dust sampling method can only measure the dust mass concentration at fixed working locations, and can not systematically reflect the spatial distribution characteristics and migration rules of the dust mass concentration in the ...

Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.

The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

Abstract Earth System Models provide spatiotemporally continuous environmental exposure data but remain underused in environmental epidemiology because of uncertainty from measurement errors. We developed a novel latent‐variable approach to correct for measurement error characterized by spatiotemporal error covariance, which was derived from ...

Applications of thermal energy storage in the cement industry [PDF]
In the manufacture of cement, literally trillions of Btu's are rejected to the environment each year. The purpose of this feasibility study program was to determine whether thermal energy storage could be used to conserve or allow alternative uses of ...

Abstract This study examines how the Russo‐Ukrainian war affected natural gas consumption and air quality in northern Italy. The conflict disrupted European natural gas supplies, leading to a reduction in residential natural gas use. We investigated how this reduction affected air quality, focusing on residential wood combustion (RWC) as an alternative

Dissolved Black Carbon in North Cascades Snow, Meltwater and a Downstream River
Abstract Quantification of black carbon on snow in the Cascade Range is needed due to increasing wildfire intensity and frequency. Here, the benzenepolycarboxylic acid (BPCA) molecular method was used to measure dissolved black carbon (DBC) in snow, nearby rivers, streams, and supraglacial melt collected in 2022 and 2023 from Mount Baker and Mount ...
