Fuzzy Similarity-Based Hierarchical Clustering for Atmospheric Pollutants Prediction [PDF]

, 2019
This work focuses on models selection in a multi-model air quality ensemble system. The models are operational long-range transport and dispersion models used for the real-time simulation of pollutant dispersion or the accidental release of radioactive ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

The Spatial Politics of Blockades: Disrupting Phosphate Industrial Production in Post‐2011 Tunisia

Area, Volume 58, Issue 3, September 2026.
Short Abstract This article examines blockades targeting the phosphate‐processing industry in Tunisia's Gabes region after the 2010–2011 uprisings, assessing both their contributions and limitations. Drawing on fieldwork conducted between 2017 and 2019, it analyses how territorially embedded and relational spatial practices enable diverse groups to ...

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4135-4150, August 2026.
Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying

Design and Construction of Deinococcus radiodurans for Biodegradation of Organic Toxins at Radioactive DOE Waste Sites [PDF]

, 1999
Immense volumes of radioactive waste, generated from nuclear weapons production during the Cold War, were disposed directly to the ground. The current expense of remediating these polluted sites is driving the development of alternative remediation ...
