The researchers found that the amino acid mixture may have stimulated the athletes' pituitary glands, increasing secretions of certain stress-and sex-related hormones, including growth hormone. They believe the mixture of amino acids, or possibly a single amino acid, could be responsible for increases in cortisol and testosterone in the blood of the athletes.
Edwards Engineering. Valance heating/cooling is a totally hydronic (forced water) system that uses no fans of blowers to furnish heating/cooling comfort. Edwards valance units, installed near the ceiling, operate by convection and radiation to heat or cool individual rooms or entire buildings.
Holding The Heat. A heat-recovery ventilator (HRV) is similar to a balanced ventilation system, except it uses the heat in the outgoing stale air to warm up the fresh air. A typical unit features two fansâone to take out household air and the other to bring in fresh air. What makes an HRV unique is the heat-exchange core.
