The activity factor used by the USDA was 1.6. In the UK, a lower activity factor of 1.4 is used. In the UK, a lower activity factor of 1.4 is used. The equation has now been replaced by the Institute of Medicine Equation in September 2002 in the US, however is still currently used by the FAO / WHO / UNU .
This corresponds to a total scientific energy gain of 0.7 and a capsule energy gain of 6. [14] While the experiment fell short of ignition as defined by the National Academy of Sciences – a total energy gain greater than one – most people working in the field viewed the experiment as the demonstration of ignition as defined by the Lawson ...
As originally formulated, the Lawson criterion gives a minimum required value for the product of the plasma (electron) density n e and the "energy confinement time" that leads to net energy output. Later analysis suggested that a more useful figure of merit is the triple product of density, confinement time, and plasma temperature T .
But among women, it took only 140 minutes of weekly exercise to see an equivalent benefit—and the risk of death was 24% lower among those who got about 300 minutes of movement per week.
The study noted that only 33% of women and 43% of men who were part of the research met the standard for weekly aerobic exercise, and just 20% of women and 28% of men completed a weekly strength ...
Formulas have been devised to estimate energy expenditure in humans, but they may not be accurate for people with certain illnesses [13] [14] [15] or the elderly. [16] Not all formula are accurate in overweight or obese individuals. [17] Wearable devices can help estimate energy expenditure from physical activity but their accuracy varies. [18]
A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven , or ...
