All of this is important to precasters because it doesn't reduce the
R-value over time.
The
r-value was significantly negative in diabetic control group (group-1) and aliskerin treated group (group-4), prior to intervention and the conversion to positive r value supports the anti-diabetic role of aliskerin.
Samples were also classified based on: the [pH.sub.45min], defined by BENDALL & SWATLAND (1988) as PSE ([pH.sub.45min] <5.80) and RFN ([pH.sub.45min]>5.80); and [pH.sub.45min] and
R-value, described by HONIKEL & FISHER (1977) as PSE (R-value>1.05 and [pH.sub.45min]<5.90), RFN (
R-value [less than or equal to] 1.05) and DFD (R-value>1.05 and [pH.sub.45min]>5.95).
As noted in the announcement for this action, reliable value ratings for home insulation products were not available from the dawn of the modern industry until FTC first adopted the
R-value Rule (16 CFR 460) in 1979 in an effort "to address the failure of the home insulation marketplace to provide essential pre-purchase information to consumers, primarily an insulation product's'
R-value.'"
In the past, these applications typically involved heavy, hard-core doors with high
R-values that minimized conduction (energy loss through the door panel).
R-value and MSE are defined by equation 7and8 respectively:
Thicker panels can be constructed by increasing the number of layers to increase the
R-value. Unlike foam insulation, the Mirrorpanel is constructed from renewable forest products resources.
The optimization of SPF physical properties, such as overall density,
R-value, percent closed-cell content, etc., is extremely important.
* Structural insulated panels typically sandwich large sheets of expanded PS foam between oriented strand board (OSB), creating large wall systems with few seams, greater
R-value, and improved strength.
* By using blue board and the R14-15 cellulose insulation, HFHMCA can boost the overall
R-Value of a house to R17-18.
They have an
R-value of 3.6 per inch, which is similar to the more toxic types but are about three times the cost of fiberglass.
Each of the computed
r-value was compared with the relevant critical
r-value at 0.05 significance levels, given the degrees of freedom.
