R-value (insulation) contain no trapped CFCs or HFCs (e.g., half-pound low density foams). On certain brands, twenty-year tests have shown no shrinkage or reduction in insulating value. This has led to controversy as how to rate the insulation of these products. Many manufacturers will rate the R-value at the time of manufacture; critics argue that a more fair assessment would be its settled value. The foam industry adopted the LTTR (Long-Term Thermal Resistance) method, which rates the R-value based on a 15-year weighted average. However, the LTTR effectively provides only an eight-year aged R-value, short in the scale of a building that
The Quality of Life Assessment of Growth Hormone Deficiency in Adults Measure a severe growth hormone deficiency, they are already receiving full replacement with other deficient pituitary hormones as they need it and they have a score of at least 11 on the QoL-AGHDA. It is also recommended that the patient’s quality of life is reassessed using the Qol-AGHDA nine months after starting therapy, and if their score is not improved by at least seven points the treatment must be discontinued. This was the first time a quality of life measure was used to determine whether treatment should be given for a specific disease. The Quality of Life Assessment of Growth Hormone
