Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Fuel to Green: Do U.S. Oil and Gas Firms Use Green Innovation and CSR Disclosure to Mitigate Financial Risk

Natural Resources Forum, EarlyView.
ABSTRACT This study aims to explore how oil and gas firms adopt two sustainability tools, namely green innovation and corporate social responsibility (CSR) disclosure, either separately or in combination, to mitigate financial risk. The empirical study examines a sample of 229 oil and gas firms over the 2010 to 2019 period.

Legitimacy in contested issue fields: How type‐based validity cues, cue congruence, and personal values shape propriety

European Management Review, EarlyView.
Abstract Contested business practices are often difficult to evaluate because they send multiple, often conflicting signals about their appropriateness. Some cues may suggest that a practice is useful, legal, or widely accepted, whereas others may suggest that it is risky, harmful, or socially opposed.

Numerical simulation of hydraulic fracture propagation after thermal shock in shale reservoir

Journal of Petroleum Exploration and Production Technology
The scale of propagation of hydraulic fractures in deep shale is closely related to the effect of stimulation. In general, the most common means of revealing hydraulic fracture propagation rules are laboratory hydraulic fracture physical simulation ...

Carbon Populism and Representative Politics: On Why Fossil Fuel Firms Speaking for ‘The People’ Is a Bad Idea

Journal of Management Studies, EarlyView.
Abstract Despite growing recognition that countries around the world must transition to a low‐carbon economy, global greenhouse gas emissions continue to rise. One way that decarbonization has been obstructed, we argue, is by fossil fuel firms intentionally conflating their agenda with ‘the people’, evoking notions of national identity, security and ...

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Elastic-wave-equation numerical simulation using a time–space domain dispersion-relation-based staggered-grid finite-difference method

Frontiers in Earth Science
Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can suppress the numerical dispersion more efficiently to

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.
