Heat distribution unit. The Heat Distribution Unit (HDU), also known as a Heat Interface Unit (HIU), provides domestic hot water (DHW) and space heating to properties that are serviced from district heating or centralised boiler plants.
Called hypoglycemia, this deficiency of glucose in the blood is considered critical at, or below, 40 milligrams of glucose per deciliter of blood, or 40 mg/dL. However, this figure must be adjusted individually, as the exact level at which an a person develops symptoms varies.
At low hematocrit levels (dashed line), most glucose systems yielded a higher glucose level relative to the YSI 2300 plasma glucose measurements and at high hematocrit levels (solid line), they yielded a lower glucose level, except the Precision G and the Precision QID, for which the glucose levels at the 3 hematocrit levels were lower than those ...
