Epilepsia Open, EarlyView.Abstract Objective Effective epilepsy management requires accurate epilepsy knowledge, active patient engagement, and stigma reduction to improve health outcomes. Educational interventions have been shown to enhance patients' quality of life (QOL) and knowledge. This study evaluated the effectiveness of EpiloBot, an artificial intelligence (AI)‐powered

Energy Science &Engineering, EarlyView.As the sublevel height increases, the top‐coal recovery amount gradually increases, but both the top‐coal recovery rate and the thickened top‐coal recovery rate show a downward trend, and the decline in the top‐coal recovery rate is gradually increasing. The comparison indicates that the optimal sublevel height is 20 m.

International Journal of Mining Science and Technology, 2020 The Atkinson equation along with its friction factor is commonly used to estimate pressure requirement in mine ventilation. However, friction factor correlation of flow through broken rock, typically found in blasted stope, gob, rock pit or block caving ...

Energy Science &Engineering, EarlyView.This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Caving-induced subsidence behaviour of lift 1 at the Palabora Block Cave Mine
, 2016 The Palabora copper mine is a large, 32 000 t/d block cave operation located in the eastern half of Limpopo, South Africa’s northern-most province. Palabora Mining Company is currently developing a second lift (Lift 2) in addition to their existing block

Energy Science &Engineering, EarlyView.This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Incorporation of 3-D Mixing in Long-term Production Scheduling Optimization for Block Caving Mines
, 2018 As open-pit mines go deeper, because of the massive amount of waste removal which is required to extract the ore as well as high operational costs per tonne, underground mining has become more attractive.

Food Chemistry International, EarlyView.Preservatives limit microbial development, oxidation, and enzymatic degradation, resulting in better food quality and extended shelf life. Classified as natural, synthetic, or biological, each preservative has distinctive attributes and modes of action. Growing preference for natural preservatives aligns with clean label trends.
