Two-dimensional transport of tokamak plasmas. [Neoclassical transport theory] [PDF]
, 1978 A reduced set of two-fluid transport equations is obtained from the conservation equations describing the time evolution of the differential particle number, entropy, and magnetic fluxes in an axisymmetric toroidal plasma with nested magnetic surfaces.

Low Z impurity transport in tokamaks. [Neoclassical transport theory] [PDF]
, 1978 Low Z impurity transport in tokamaks was simulated with a one-dimensional impurity transport model including both neoclassical and anomalous transport. The neoclassical fluxes are due to collisions between the background plasma and impurity ions as well as collisions between the various ionization states. The evaluation of the neoclassical fluxes takes

Journal of Transport and Supply Chain Management, 2017 Background: There has been considerable decline in the investment on road transport infrastructure in recent times, as a result of the dwindling economic investment owing to lowering gross domestic product (GDP) since 2009.

Disparate clump approximation in neoclassical plasma transport theory [PDF]
, 1978 A model of a multiple ion plasma is considered in which the system may contain many atomic species, each with an arbitrary number of charge states, but in which the atomic species are disparate in mass. Using this approximation is calculated in analytic form, the multispecies Spitzer function, from which there follow tractable expressions for the Ware ...

Charge dependence of neoclassical and turbulent transport of light impurities on MAST [PDF]
, 2015 Carbon and nitrogen impurity transport coefficients are determined from gas puff experiments carried out during repeat L-mode discharges on the Mega-Amp Spherical Tokamak (MAST) and compared against a previous analysis of helium impurity transport on ...

THE LARGE ASPECT RATIO LIMIT OF NEOCLASSICAL TRANSPORT THEORY [PDF]
, 2002 OAK B202 THE LARGE ASPECT RATIO LIMIT OF NEOCLASSICAL TRANSPORT THEORY. This article presents a comprehensive description of neoclassical transport theory in the banana regime for large aspect ratio flux surfaces of arbitrary shapes. The method of matched asymptotic expansions is used to obtain analytical solutions for plasma distribution functions and

Adapting Agriculture to Climate Change: Are Climate-Smart Practices Important in Burkina Faso? [PDF]
Plant Environ InteractABSTRACT In Burkina Faso, smallholder farmers rely heavily on rain‐fed agriculture, which is affected by climate change. The adoption of climate‐smart practices is essential to strengthen the resilience of agricultural systems to climate change and improve household food security and, consequently, global food security.

Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls [PDF]
, 2019 This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another (pulse 92432) from after the installation of JET's ITER-like Wall (ILW ...
