Statement of Harold P. Furth

چکیده
Since the initiation of the Tokamak Fusion Test Reactor (TFTR) project, in 1975, the fusion program has made steady progress toward the understanding of hot-plasma confinement and the production of useful energy. One way we measure our progress is by comparing the fusion power that is generated in a .hot plasma with the power that is required to heat the plasma:” The experiments of the mid-70’s still had a factor of a thousand or more to go towards the achievement of break-even conditions, where the fusion power equals the plasma-heating power. As of last year’s TFTR run, there is less than a factor of five to go. I find it particularly encouraging that last year’s TFTR results were achieved using only a fraction of the full TFTR plasma current and a fraction of the plasma-heating power that is now available. During this year’s TFTR run, we hope to advance to within a factor of two of break-even conditions.

The Philosophy and Functions of Verbal Violence in Harold Pinter’s Mountain Language: A CDA Approach
The present study considers the issue of verbal violence in the language of drama. In the evaluation of verbal violence, Jeanette Malkin (2004) proposes six maxims, through which language may be considered as an arrogant element. The characters in dramatic texts (as in other literary texts) are created, developed, evolved and - in some cases - destroyed by language. In a considerable numb...
متن کاملRole of citrate synthase in aldosterone-mediated sodium reabsorption.
Aldosterone and other mineralocorticoids increase citrate synthase activity in the kidney and enhance renal sodium reabsorption, but it is unclear whether the increased citrate synthase activity is involved in renal sodium transport. We used the Wistar-Furth rat, an inbred strain found to be deficient in renal citrate synthase activity, as an experimental model to investigate this issue. We con...
