Air or moisture can be trapped in one side of the system and will eventually let go and therefore a higher reading on the micron gauge will occur. Sometimes moisture can be trapped in the oil of the compressor and when it escapes it will show up in the gauge.
Heat generation, metabolic rate, and regulation of many other things are just some of the functions regulated by the thyroid hormones.hyroxine Thyroxine     thyroxine (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland the thyroid and parathyroid glands are in the neck. the thyroid harmones accelerate the metabolic rate and oxygen consumption in all body tissues.
The regulation of body functions by the endocrine system depends on the existence of specific receptor cells in target organs that respond in specialized ways to the minute quantities of the hormonal messengers. Some endocrine hormones, such as thyroxine thyroxine, substance secreted by the thyroid gland.The hormone thyroxine forms by combining the amino acid tyrosine with iodine. Complexed to a protein, it is stored in the follicle stems between thyroid cells......he regulation of body functions by the endocrine system depends on the existence of specific receptor cells in target organs that respond in specialized ways to the minute quantities of the hormonal messengers.
