This includes over 70 randomized controlled trials, 50 clinical outcomes studies, 5 meta-analyses, 4 systematic reviews of various energy psychology modalities, and 9 comparative reviews of energy psychology with other therapies such as EMDR and cognitive behavioral therapy. All but one of the experimental studies have documented the ...
Concentrating on a task, one aspect of flow. Flow in positive psychology, also known colloquially as being in the zone or locked in, is the mental state in which a person performing some activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity.
This imparts additional energy to the propellant, so that one can extract more work out of each kilogram of propellant, at the expense of increased power consumption and (usually) higher cost. Also, the thrust levels available from typically used arcjet engines are very low compared with chemical engines.
Energy–maneuverability theory is a model of aircraft performance. It was developed by Col. John Boyd , a fighter pilot, and Thomas P. Christie , a mathematician with the United States Air Force , [ 1 ] and is useful in describing an aircraft's performance as the total of kinetic and potential energies or aircraft specific energy .
The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [citation needed] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage). The resulting ...
Actuality is often used to translate both energeia (ἐνέργεια) and entelecheia (ἐντελέχεια) (sometimes rendered in English as entelechy). Actuality comes from Latin actualitas and is a traditional translation, but its normal meaning in Latin is 'anything which is currently happening.'
The particular take-off distance required may be shorter than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature.
A rocket acting on a fixed object, as in a static firing, does no useful work on the rocket; the rocket's chemical energy is progressively converted to kinetic energy of the exhaust, plus heat. But when the rocket moves, its thrust acts through the distance it moves. Force multiplied by displacement is the definition of mechanical work. The ...
