INDEX release factor

The elasticity of a fiber describes its abiUty to return to original dimensions upon release of a deforming stress, and is quantitatively described by the stress or tenacity at the yield point. The final fiber quaUty factor is its toughness, which describes its abiUty to absorb work. Toughness may be quantitatively designated by the work required to mpture the fiber, which may be evaluated from the area under the total stress-strain curve. The usual textile unit for this property is mass pet unit linear density. The toughness index, defined as one-half the product of the stress and strain at break also in units of mass pet unit linear density, is frequentiy used as an approximation of the work required to mpture a fiber. The stress-strain curves of some typical textile fibers ate shown in Figure 5. 

The surface burning characteristics (flame spread index and smoke developed index) for wood and wood products as measured by American Society for Testing and Materials (44) can be reduced with fire retardant treatments, either chemical impregnation or coatings (48). Fire retardant treatments also reduce the heat release rate of a burning piece of wood (49,50). The heat release rates (51) of the burning materials are an important factor in fire growth. 

The second difference relates to the definition of a cutoff time point for the evaluation of the difference factor and the Rescigno index. When cumulative data are available, evaluation of the difference factor or the Rescigno index usually requires a reference data set in order to define the cutoff time point for index evaluation (30). For the evaluation of fl and the , i.e., when the difference factor and the Rescigno index are evaluated from non-cumulative data, this difficulty does not exist, provided that the release process has been monitored up to the end (i.e., until dissolution of the drug is complete). At this point, it is worth mentioning that a similar conclusion cannot be drawn for the similarity factor (31) because application of this index to non-cumulative data is set apart by the careful scaling procedure required, in addition to the existence of a reference data set. The reason is that this index can continue to change even after dissolution of both products is complete. 

Fig. 7.15 Approach to assess a MIP/NIP library in the SPE mode. After quantitative nonspecific adsorption of the analyte from water the analyte is gradually eluted from the cartridge by increasing the acetonitrile content in the wash steps. The cumulative recovery is plotted against % acetonitrile in the wash step. The hydrophihcity index is defined as the % water present in the wash solvent leading to 50% release of the analyte from the NIP. The cumulative imprinting factor is defined as the ratio of the recovery from the NIP at that point (=50%) over that from the MIP (= Y)...

Hydrogen powered cars are assessed similarly to transport units. In fact for a mobile unit, credit factors of releases caused by crash accidents can be considered at least an order of magnitude more probable than operative failures. Overall indices for a single vehicle are reported in Table 4. The analysis of both the potential index (PI) and the hazard index (HI) immediately reveals that the innovative technology of metal hydrides yields safer storages by the application of the moderation principle of inherent safety (CCPS, 1996).
