Identification, prediction and mitigation of sinkhole hazards in evaporite karst areas [PDF]

, 2008
Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in evaporite terrains than in carbonate karst areas. This is because evaporites have a higher solubility, and commonly a lower mechanical strength.

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

Advanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Food insecurity and unemployment among immigrants in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Ground residual subsidence during post-mining period based on Sentinel-1 and PS-InSAR technology: the Shendong coal field (China) case study

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
The residual subsidence induced by coal mining activities leads to long-time ground subsidence and compromises the stability of surface structure. To provide a better understanding of the long-term residual subsidence during the post-mining period under ...

Surface dynamic subsidence prediction model based on multi-function crossover and its application

Meikuang Anquan, 2023
In order to study the dynamic influence of working face mining on surface subsidence, taking a mine in Wuhai as the engineering background, the prediction function model of surface dynamic subsidence is constructed by using Knothe time function and ...

An Evaluation of Mortality Rates and Their Determinants in a Cohort of Former Asbestos Miners in South Africa

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background A causal association between occupational asbestos exposure and lung disease, including pneumoconiosis and mesothelioma, is well established. Elevated mortality among former asbestos miners is expected. However, large‐scale South African studies examining all‐cause mortality in this population are lacking.

Mine Geological Environment Monitoring and Risk Assessment in Arid and Semiarid Areas

Complexity, 2021
Along with the accelerated shift of coal mining to the ecologically fragile west, the contradiction between coal resource development and ecological protection in the western arid and semiarid coal mining areas is rapidly intensifying. Based on the above

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that
