In terms of acoustic performance, the walls and shafts reportedly have to meet a minimum weight sound reduction index
of 46 decibels (46RwdB), at heights of up to 5.
To remedy patient and visitor discomfort in that area, the team installed 14-foot-tall insulated panels with a high solar reduction index
on the facade.
Traditional acoustic isolation calculation methods show important deviations for various reasons - for example, the approaches taken to the characteristic parameters of building structures and the influence of the joint compression on the vibration reduction index
The cytotoxicity of the photodynamic treatment and [beta]-Lapachone alone or in combination was determined by KFT assay and the combination index (CI)-isobologram method and the dose reduction index
(DRI) analysis were used to assess the effect of drug combinations.
Case studies of the river city Sondrio in the Italian Alps highlight the problems analysts face when implementing flood forecast verification methods, damage assessment tools, and a damage reduction index
The data presented in this paper are expressed in terms of sound transmission loss, which is equivalent to sound reduction index
The electric field effectiveness in controlling the frost accumulation is computed measuring the frost mass accumulated on the two extractable plates and calculating the Mass Reduction Index
according to the following equation:
As the results show the application of a thicker-layer material for the same structure does not produce a better value of the airborne sound reduction index
Drawing on a Perimeter Reduction Index
(PRI) and the GIUR, Law argues for an increase in the frequency of residential moves based on the late Puritjarra sequence.
1993), and particle size reduction index
(Culvenor and Casler, 1999).
It also has good sound reduction index
, fire resistance properties, cost effective and easy to fabricate and install.
The dose reduction index
(DRI) or reversal ratio, or cytotoxicity enhancement ratio, is a measure of how many -fold the dose may be reduced as compared with the doses of each drug alone (Chou and Chou 1988), is calculated as follows:
