ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY [PDF]

Journal of Sciences, Islamic Republic of Iran, 1993
The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical

Integrated modelling of tungsten accumulation control with wave heating: validation in ASDEX Upgrade and predictions for ITER

Nuclear Fusion
In present-day fusion devices, central wave heating is crucial to avoid core tungsten (W) accumulation. In this work, we present an integrated modelling framework that reproduces the reduction of core W peaking in ASDEX Upgrade experiments when multiple ...

Accounting for the Evolution of China's Production and Trade Patterns

International Economic Review, EarlyView.
ABSTRACT We study the evolution of China's production and trade patterns during its integration into the global economy. Using firm‐level microdata, we document how production and exports shifted across industries and within industries across firms.

Geometry effects on zonal flow dynamics and turbulent transport in optimized stellarators

Nuclear Fusion
Global gyrokinetic simulations find a strong suppression of ion temperature gradient (ITG) turbulence by zonal flows in stellarators optimized for neoclassical transport.

The Impact of Canada's Working Income Tax Benefit on the Labor Supply of Low‐Income Workers

Industrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT We use administrative tax data to estimate the effect of the Working Income Tax Benefit (WITB) on the labor supply of single, low‐income workers in Canada. Our analytical approach exploits low knowledge of the program, which generates variation in the benefit receipt both between and within eligible tax filers over time.

Effect of 4.6 GHz LHW on tungsten transport in NBI dominant H-mode plasma in EAST tokamak

Nuclear Fusion
Experimental observations in EAST tokamak have revealed a notable suppression of tungsten accumulation during the lower hybrid wave (LHW) injection in the neutral beam injection (NBI)-heated H-mode plasma.

The Capital–Labour–State Dynamics of Herbicide Adoption in Rainfed India

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper engages debates around the capital–labour–state dynamics of agrarian transitions to address the oft‐studied but still little‐understood question of why farmers adopt herbicides when they do. Over the last several years, smallholder farmers in India have begun using the herbicide bispyribac sodium at breakneck speeds, particularly in

Isotope effects on transport characteristics of edge and core plasmas heated by neutral beam injection (NBI) in an inward shifted configuration at the Large Helical Device

Nuclear Fusion
Isotope effects have been investigated in Neutral Beam Injection (NBI) heated plasmas on the Large Helical Device with similar operational parameters between Hydrogen (H) and Deuterium (D) plasmas.

Rural Capitalists and Development in Colonial Africa: A Comparative Analysis

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper explores the emergence and role of rural capitalists in colonial Sub‐Saharan Africa by comparing three peasant‐based economies: Bechuanaland, the Gold Coast and Tanganyika. Using social tables, we estimate the population and income shares of better earning agricultural producers and assess their impact on rural inequality and ...
