BACKGROUND The number of older adults participating in yoga has increased dramatically in recent years; yet, the physical demands associated with yoga performance have not been reported. The primary aim of the Yoga Empowers Seniors Study (YESS) was to use biomechanical methods to quantify the physical demands associated with the performance of 7 commonly-practiced standing yoga poses in older a...

ITER envisages the use of two heating neutral beam injectors plus an optional one as part auxiliary and current drive system, to reach desired performances during its various phases operation. The 16.5 MW expected power per injector is several notches higher than worldwide existing facilities. In order enable such development, a Neutral Beam Test Facility (NBTF) was established at Consorzio RFX...

It is shown that high accelerating gradient can be obtained in a specially constructed system of electron (positron) bunches, moving in cold plasma with definite density. These combined bunch systems do not generate the wake fields behind them and can pass through the plasma column in a periodic sequence. The consideration is carried out numericaly and analyticaly in one dimensional approach, (...

In his treaty Physics and Philosophy, the renowned physicist Sir James Jeans started with following opening statement:1 “Science usually advances by a succession of small steps, through fog in which even most keen-sighted explorer can seldom see more than few paces ahead. Occasionally lifts, an eminence is gained, wider stretch territory be surveyed – sometimes startling results.” Jeans, as he ...
