All skills of our physicians like their leadership skills, empathy, professional skills and the skills as spouse and parent all depends on a positive energy balance
. Unfortunately our physicians and residents are not trained to notice or care for their energy levels due to their professional workload, economic burden to maintain their life standards and lack of recreational activities6.
The pregnancy cows, which graze in the dry season during the last gestation period, have been related to weight loss, loss of body condition score and high concentration of NEFA and [beta]HBA, leading to long periods of negative energy balance, this, adequate prepartum nutrition through supplementation, improved nutrient intake, and positive energy balance
This allows the compressor to supply intake air to the engine at an adequate air pressure, thereby preserving the engine full power and maintaining a positive energy balance
of the turbocharger.
 found that the use of crude glycerol for biodiesel production is the only process that has an energy gain, with a positive energy balance
and conversion efficiency greater than 1, which is in agreement with our results.
In 2011, OriginClear helped launch Ennesys to target France's sustainable energy law, RT 2020, which will require that buildings achieve a positive energy balance
by the year 2020.
The positive energy balance
obtained indicates the viability of biodiesel production from canola under the given production conditions.
In the CNS, neuropeptides modulate inflammation and migration of peripheral cells into the CNS via the BBB and may represent a molecular node during positive energy balance
as is the obesity and maternal overnutrition.
The authors have organized the main body of their text in fourteen chapters devoted to energy, negative energy balance, positive energy balance
, regulation of food intake, exercise, cell cycle and life cycle, nutrigenomics, protein, carbohydrates, lipids, fat-soluble vitamins, water-soluble vitamins, macrominerals, and trace minerals.
Undernutrition was 68.50% and 57.53% in subjects with negative and positive energy balance
, respectively (p>0.05)(Table 2).
The typical Western diet is high in energy-dense foods, fat and refined sugar  that easily lead to a positive energy balance
. This is especially true in the presence of decreased physical activity During the process of urbanisation and westernisation, children (and adults) consume more snacks and convenience foods, which are very high in salt, fat, refined sugar and energy.
"With significant emissions reductions, a positive energy balance
, nutrient recycling and CO2 reuse, algae-based fuels will be a long-term, sustainable source of fuels for our nation."
