Fundamental mechanisms governing the erosion and prompt re-deposition of tungsten impurities in tokamak divertors are identified and analyzed to inform the lifetime of tungsten plasma-facing components in ITER and other future devices. Various experi

Human amylase gene copy number variation as a determinant of metabolic state
Autor: Patrick J D Elder, David Burnett, Thomas M. Barber, David B. Ramsden, Martin O. Weickert
Publikováno v: Expert Review of Endocrinology & Metabolism. 13:193-205
Introduction\ud \ud Humans have multiple genes encoding amylase that are broadly divided into salivary (AMY1) and pancreatic (AMY2) genes. They exhibit some of the greatest copy numbers of any human gene, an expansion possibly driven by increased die

Transport and deposition of 13C from methane injection into partially detached H-mode plasmas in DIII-D
Autor: Adam McLean, J. D. Elder, P.C. Stangeby, William R. Wampler, N.H. Brooks, D.G. Whyte, M.E. Fenstermacher, W.P. West, S.L. Allen, M. Groth
Publikováno v: Journal of Nuclear Materials. :72-77
Experiments are described which examine the transport and deposition of carbon entering the main plasma scrape-off layer in DIII-D. 13 CH 4 was injected from a toroidally symmetric source into the crown of lower single-null partially detached ELMy H-

FLUSH SYSTEMS AND SAND
Autor: R. Petty, J. D. Elder
Publikováno v: Fifth International Dairy Housing Conference for 2003.
Flush systems are a reliable and efficient method of removing animal wastes from dairy freestall barns. A flush system that is properly designed and correctly installed will keep a freestall barn free of animal wastes providing a sanitary environment

The Effect of Flow Reversal on Impurity Behaviour in Tokamaks
Autor: Detlev Reiter, P.C. Stangeby, G. P. Maddison, J. D. Elder
Publikováno v: Contributions to Plasma Physics. 34:306-311
Results are reported for a study of impurity edge transport and core contamination in the presence of flow reversal of the DT plasma, using 2-D plasma solutions for the ITER CDA configuration produced by the B2 fluid code, coupled to the EIRENE Monte

The Relative Importance of Wall and Target Impurity Sources in Divertor Tokamaks
Autor: P.C. Stangeby, J. D. Elder
Publikováno v: Contributions to Plasma Physics. 32:353-364
Experiments in JET operated with X-point discharges have shown that wall-produced impurity influxes can be significantly more effective at contaminating the core plasma than plate-produced influxes. The DIVIMP (Divertor Impurity) Monte Carlo impurity

Some possibilities for measuring local plasma parameters in the edge plasma by impurity injection
Autor: J D Elder, P.C. Stangeby
Publikováno v: Plasma Physics and Controlled Fusion. 33:1435-1452
Some opportunities for measuring nc, Te, Ti, Zeff and background plasma drift velocities in the edge region of magnetic confinement devices based on impurity injection are described. The technique would be based on spatially resolving (along B) the d
