Moment equation approach to neoclassical transport theory

, 1977
The neoclassical cross-field fluxes for a toroidally confined, axisymmetric plasma are calculated in terms of the thermodynamic forces from the fluid continuity and momentum balance equations. This macroscopic formulation of neoclassical transport theory

Controlling impurity transport in 5D gyrokinetic simulations using a transport barrier

Nuclear Fusion
The effects of transport barriers on impurity transport, specifically helium (He) and tungsten (W), are investigated using the global, flux-driven, full-F, 5D gyrokinetic code GYSELA.

Lagrangian formulation of neoclassical transport theory [PDF]

The Physics of Fluids, 1983
Neoclassical transport theory is developed in a Lagrangian formulation in contrast to the usual Eulerian development. The Lagrangian formulation is constructed from the three actions: magnetic moment, parallel invariant, and bounce-averaged poloidal flux.

Advancing SDG 13 and Net‐Zero Emissions in Europe: The Role of Green Technology Innovation, Renewable Energy, Environmental Taxation and Trade Openness

Sustainable Development, EarlyView.
ABSTRACT The European Union (EU) has set ambitious climate goals, aiming to become the first climate‐neutral continent by 2050, with a focus on achieving net‐zero emissions and advancing United Nations Sustainable Development Goal (SDG) 13. A key component of this transition is the role of green technological innovation, the deployment of clean energy ...

Examination of Afghanistan's Development Traps

Regional Science Policy &Practice, EarlyView., 2022
Abstract We examine the factors behind Afghanistan's persistent underdevelopment. Drawing on various theories of development traps operating at the demographic, economic and institutional levels, we seek to assess whether and to what extent their functioning affects Afghanistan's development. To capture the functioning of development traps empirically,

Understanding Farmer Behaviour for Successful Climate Change Mitigation in Voluntary Initiatives

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Private and voluntary initiatives, such as voluntary carbon markets, can support public policies aimed at reducing greenhouse gas (GHG) emissions in agriculture. This study investigates the impact of behavioural factors (reluctance to change) and social dynamics (peer imitation) on the adoption of two mitigation practices on Swiss dairy and ...

Resilience in a noisy urban system

Regional Science Policy &Practice, EarlyView., 2023
Abstract The ability of cities to recuperate from disturbances and return to their evolutionary pathways depends, first and foremost, on the type of damage that the shock created. But in addition, it depends on how information is transmitted in the urban system and on how noise filters distort the information that reaches economic agents.

Exploration of the parameter space of piecewise omnigenous stellarator magnetic fields

Nuclear Fusion
Piecewise omnigenous fields are stellarator magnetic fields that are optimized with respect to radial neoclassical transport thanks to a second adiabatic invariant that is piecewisely constant on the flux-surface.

Policy Evaluation for Climate Mitigations in the European Agricultural Sector—A Comparison of Policy Options at Micro and Macro Level

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...
