2D distribution of hydrogen/impurity radiation and flow formation in stochastic layer during detachment transition in LHD

Nuclear Materials and Energy, 2017
2D distribution of hydrogen/impurity radiation and impurity flow have been measured in the edge stochastic layer of LHD during detachment transition by using a newly developed visible spectrometer system with 130 channel optic fiber array.

Critical Discourse Analysis in Corporate Reports: Legitimation Strategies in the Context of Environmental Controversies

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the use of environmental disclosure as a strategic tool to manage legitimacy crises in a mining company, adopting critical discourse analysis (CDA) as the main methodology. Focusing on a case of environmental disaster, this research reveals how corporate narratives can be manipulated to minimize responsibility and reinforce

UEDGE modelling of detached divertor operation for long‐leg divertor geometries in ARC

Contributions to Plasma Physics, 2018
Simulations of the ARC scrape‐off layer and divertor configuration are carried out using UEDGE to perform the first power‐handling assessment for the divertor design. A convective–diffusive anomalous transport model is implemented in the code to reproduce the radial plasma profiles anticipated for the device at the outer mid‐plane.

Market Perceptions of ESG Reputational Risk in the US Pharmaceutical Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Negative ESG‐related reputational events generate significant corporate risks, particularly within sensitive sectors such as the pharmaceutical industry. Using novel reputational data, this research investigates investor perceptions of the consequences of experienced ESG breaches among US pharmaceutical firms.

Digital Transformation in Work Integration Social Enterprises: Leadership Strategies and the Role of Internal Stakeholders

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Digital transformation is increasingly reshaping how social enterprises organize work, engage stakeholders, and pursue social value. While prior research has examined digitalization in hybrid organizations, limited attention has been paid to how responsibility for inclusive digital transformation is enacted internally.

Regulation compliant AI for fusion: explainable image-based feedback control of divertor detachment in DIII-D tokamak

Nuclear Fusion
While artificial intelligence (AI) has been promising for fusion control, its inherent black-box nature will make compliant implementation in regulatory environments a challenge.

Thermal front analysis of detached divertors and MARFEs [PDF]

Nuclear Fusion, 1994
A non-linear analysis is presented of localized regions of strong divergence of parallel heat flux-thermal fronts-in the edge and scrape-off layers of tokamaks. The phenomena of divertor detachment and MARFEs are discussed in terms of one dimensional thermal conduction in the parallel co-ordinate, but retaining cross-field transport power divergence ...

An Estimation of the Heat Load Distribution on the Divertor Target Using the CSD Model

Contributions to Plasma Physics, EarlyView.
ABSTRACT Handling the heat load on the divertor target is a critical issue in the design of fusion reactors. Estimating the heat load, supported by computationally efficient simulations with varying design parameters, provides valuable input to high‐level design discussions and the development of design guidelines.

Radiative detached divertor with acceptable separatrix Zeff

Physics of Plasmas, 2017
The feasibility study is performed for the radiative detached divertor (RDD) concept, which characterizes a variety of detached plasmas with impurity amounts providing the highest levels of divertor radiation without X-point MARFE (XPM), based on a set of restrictive criteria for the leading plasma parameters (LPPs) including, e.g., tolerable peak ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that
