From quantity to quality: the evolution of forest restoration in the United Kingdom
Abstract Introduction Over the past century, forest cover in the United Kingdom has increased threefold. However, the pathways, achievements, and shortcomings of this expansion remain underexplored. Objectives This study analyses the drivers, implementation, and legacies of forest restoration in the United Kingdom before and after 1990, which is when ...

Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Geological and Geochemical Features of Alborz Basin Coal Deposits, Iran [PDF]
The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin.

OUT OF TIME? Chronocracy and Ageism in Brexit–COVID‐19 England
ABSTRACT Generation or relative age is a common way humans define social difference. In Europe and North America, old age is frequently perceived as a period of decline and loss, a condition “successful aging” paradigms exhort individuals to avoid for as long as possible. Explicit and implicit ageist beliefs, discourses, and practices marginalize later

Coal extraction has been occurring in the Midwestern United States for over a century. Despite the pre-mining history of the landscape as woodlands, spent surface coalfields are often reclaimed to grasslands.

Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.

This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
