Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

The Evolution of Electrochemical and Safety Properties of Nonflammable Triethyl Phosphate Based Electrolyte Under Salt Concentration Control

open access: yesSafety Science and Technology, EarlyView.
By regulating the lithium salt concentration to alter the solvation structure of Li+, and subsequently affecting the chemical composition of the SEI, the evolution of salt concentration on the electrochemical and safety performance of cells are explored. ABSTRACT Phosphates exhibit excellent flame retardancy. Phosphate‐based electrolytes with high‐salt‐

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Opportunities for the Labour Party: Football, Class and Community Renewal

open access: yesThe Political Quarterly, EarlyView.
Abstract This article argues that football represents an underutilised opportunity for the Labour Party to anchor a wider programme of civic renewal. In many working‐class communities, the decline of trade unions, working men's clubs and other associational spaces has eroded collective life, leaving football clubs as rare institutions where dignity ...

Effect of blast induced rock fragmentation and muckpile angle on excavator performance in surface mines [PDF]

open access: yes, 2019
Purpose. A fit excavator in a surface mine gives a trouble free production. To maintain the condition and safety of an excavator, proper sizes of rock fragmentation and muckpile parameters are crucial besides its maintenance.

Agrarian counterpoint

open access: yesAmerican Ethnologist, EarlyView.
Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

Study on Dust Hazard Levels and Dust Suppression Technologies in Cabins of Typical Mining Equipment in Large Open-Pit Coal Mines in China

open access: yesAtmosphere
As the world’s largest open-pit coal producer, China faces severe dust pollution in mining operations. Cabins of mining equipment (electric shovels, haul trucks, drills) exhibit unique micro-environmental contamination due to dual-source pollution ...

Behavioral and demographic effects of open‐pit mining on Central Mountain Caribou in British Columbia

open access: yesConservation Science and Practice, EarlyView.
The demographic manifestation of mining effects on caribou, a species listed as Vulnerable on the IUCN Red List of Threatened Species, has been disputed. We characterized a cascade of events for caribou associated with open‐pit coal mining beginning with maladaptive behavior responses leading to negative demographic outcomes for the affected caribou ...
