An Analytical Review of Reckless Driving in Ghana: Causes, Consequences and Regulatory Responses

Public Health Challenges, Volume 5, Issue 3, September 2026.
Reckless driving in Ghana is driven by behavioural norms, economic pressures, weak enforcement and infrastructural deficits. Integrating the theory of planned behaviour and the safe systems approach, this review shows how coordinated reforms, speed management, safer infrastructure, licensing modernization and institutional strengthening can reduce ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Persons Enough to Punish: Illegality, Deportability and the Hierarchy of Personhood in US Immigration

International Migration, Volume 64, Issue 5, September 2026.
ABSTRACT This paper argues that contemporary United States immigration law and policy construct a hierarchy of personhood for undocumented migrants which better explains their status as opposed to a classic binary framework of citizen/migrant. It develops a four‐layer conceptual framework of personhood including baseline personhood, membership ...

Geography and ‘The New’

Transactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.
ABSTRACT This Intervention reflects on the multiple, contradictory and ambivalent relations human geography has with ‘the new’. Some sort of relation with the new is an inescapable and necessary part of all practices of knowledge generation. Newness, whether it be an empirical finding, an idea, a concept or an approach, can fuel the interest, wonder ...

Advanced cladding materials for accident tolerant fuels

, 2019
In terms of safety, nuclear fuel cladding is one of the main barriers in preventing the release of radioactive materials to the environment.The integrity of the fuel cladding is essential both in operation and in the long-term storage of spent nuclear fuel, not to mention accident conditions.In this paper, we review shortlyrelevantaccident tolerant ...

A hidden Markov model and reinforcement learning‐based strategy for fault‐tolerant control

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4322-4336, August 2026.
Abstract This study introduces a data‐driven control strategy integrating hidden Markov models (HMM) and reinforcement learning (RL) to achieve resilient, fault‐tolerant operation against persistent disturbances in nonlinear chemical processes. Called hidden Markov model and reinforcement learning (HMMRL), this strategy is evaluated in two case studies

Neutronic examination of the U–Mo accident tolerant fuel for VVER-1200 reactors

Nuclear Engineering and Technology
In this study, we investigated the possibility of employing accident tolerant fuel (ATF) in VVER-1200/V491 assembly without gadolinium-containing fuel rods using the Monte Carlo code Serpent 1.1.7 with ENDF/B-VII cross-section library.

Iron-chrome-aluminum alloy cladding for increasing safety in nuclear power plants

EPJ Nuclear Sciences & Technologies, 2017
After a tsunami caused plant black out at Fukushima, followed by hydrogen explosions, the US Department of Energy partnered with fuel vendors to study safer alternatives to the current UO2-zirconium alloy system.

Transient Response Analysis of Quasi‐Synchronization and Self‐Synchronization Grid‐Connection Processes for Nuclear Power (N + X) Emergency Diesel Generator Units

Engineering Reports, Volume 8, Issue 8, August 2026.
The upper portion condenses the five‐unit EDG arrangement into repeated diesel–governor and generator–AVR modules, distinguishing four operating units from one standby unit. Measured data and the equipment configuration jointly support a calibrated full‐system model, which then feeds two parallel research tracks covering self‐synchronization and quasi ...

Dispersion type metal-metal based high-density fuels for nuclear reactors – sample preparation, analysis and examination of LOCA behaviour

Acta Polytechnica CTU Proceedings
Metal-based nulear fuels have been proposed as an alternative to UO2 partly in response to increasing pressure to continually improve nuclear system safety.
