Lagrangian neoclassical transport theory applied to the region near the magnetic axis

Physics of Plasmas, 2002
Neoclassical transport theory around the magnetic axis of a tokamak is studied, in which relatively wide “potato” orbits play an important role in transport. Lagrangian formulation of transport theory, which has been investigated to reflect finiteness of guiding-center orbit widths to transport equations, is developed in order to analyze neoclassical ...

Benchmark Test of Drift-kinetic and Gyrokinetic Codes through Neoclassical Transport Simulations [PDF]

, 2009
Two simulation codes that solve the drift-kinetic or gyrokinetic equation in toroidal plasmas are benchmarked by comparing the simulation results of neoclassical transport.

Radio frequency induced and neoclassical asymmetries and their effects on turbulent impurity transport in a tokamak

, 2013
Poloidal asymmetries in the impurity density can be generated by radio frequency heating in the core and by neoclassical effects in the edge of tokamak plasmas.

On an Aggregation Theory for Indicators Expressing Behaviors of Complex Systems With an Application to Sustainability

Sustainable Development, EarlyView.
ABSTRACT Certain attributes of large‐scale complex systems are often expressed through sets of indicators. For example, the sustainability of an entity, be it a nation, a city, an energy system, a corporation etc., can be effectively represented by indicators and corresponding data series.

Advancing Sustainable Development Through Exports of Clean Energy Products From Emerging Asian Economies: A Poisson Pseudo Maximum Likelihood Estimation Approach

Sustainable Development, EarlyView.
ABSTRACT The promotion of clean energy is critical to achieving sustainable development. This study investigates the factors that affect the exports, trade potential, and revealed comparative advantage (RCA) of clean energy products (CEPs) in the emerging Asian economies (EAEs).

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 ...

ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Collision frequency dependence of polarization current in neoclassical tearing modes

, 2012
The neoclassical polarization current, generated when a magnetic island propagates through a tokamak plasma, is believed to influence the initial stage of the neoclassical tearing mode evolution.

How Can Accountants Enhance (or Save) Natural and Cultural Capital Valuation? Engaging Academics: A Collaboration with CPA Canada and the Canadian Commission for UNESCO*

Accounting Perspectives, Volume 24, Issue 1, Page 21-46, March 2025.
ABSTRACT Accountants should engage more with natural and cultural capital accounting to make tools more accessible and to ensure critical information is provided to decision‐makers. While ecological economists have continued to innovate and design tools, corporate‐level accounting has seemingly lagged behind.
