Weighting process

An indicator result could, for instance, be compared to the total indicator value in an area, or to the average indicator value per inhabitant per year. Other common methods are to compare with national reduction targets and with damage costs from emissions and resource depletion. Sometimes these are weighed across impact categories made by expert panels. However, some studies using this technique would not meet the requirement of transparency for the weighting process set by ISO.

Notice that all the above dependencies assume that i is proportional to C and g independent of C, that is the chain length must be sufficiently long that a nucleation and spreading model is still valid. At very low molecular weights process (iv) will be important and may predominate the effects considered here. 

At very low molecular weights process (iv) will become important [49]. Then at least two molecules are required to form a stable nucleus5, and they must both join the surface at approximately the same time so that a relatively large increase in concentration is needed to significantly enhance the nucleation rate, that is, y > 1. Although Sanchez and Di Marzio made this more quantitative there are too many other complicating effects to make general approximations. 

The values given here are for resins with relatively low levels of additives. Resins with fillers or low molecular weight processing aids can have physical properties considerably different from these... 

Numerous factors affect various mechanical properties of polymers, including molecular weight, processing, extent and distribution of crystallinity, composition of polymer, and use temperature.

The use of the Brabender Plasticorder is widespread in the development and quality control of formulations destined to be used in uPVC foam extrusion applications. The morphology transformations associated with the process have been widely studied but the particularities of the application have not often been taken into account - low K-value and high concentration of high molecular weight process aid. This work uses a commercially viable formulation to examine the fusion aspect of the transformation process. Differential scanning calorimetry is used to observe the degree of fusion. 9 refs. 

The water absorption and desorption by the stoppers, used to close the vials after drying, depends on the various materials from which they are made [11]. It is possible to reduce the water absorption by changing the materials for the stopper, but a certain amount will always be absorbed, especially after steam sterilization, e.g., 1% of weight. Processes to reduce the water content before using the stoppers are mentioned in Section IV.D. 

This suggests the use of such a weighting process, perhaps with... 

Highly cross-linked epoxy resins combine high strength stiffness thermal, chemical, and environmental stability adhesion low weight processability excellent creep resistance and favorable economics. These resins are widely applied as coatings, casting resins, structural adhesives, and matrix resins of advanced composite materials. The broad spectrum of applications ranges from the automotive and aerospace industries to corrosion protection and microelectronics. 

The weighting process is merely an extension of the general variance-covariance matrix of the standard regression model, where w = weight values, 1/w, as diagonals and all other element values are 0, as in Equation 8.7. 

The index J indicates either the first or second peak, while i runs over the peak in question. The values which correspond to 2 are shown in Fig. 1+. In a z-average weighting process, only for the high molecular weight fraction, influences the radius of gyration for the entire system. 

With regard to passive materials for external packaging there has been continuous improvement in traditional properties, such as strength, durability, clarity, moisture resistance, less weight, processability, appearance, and design as well as their new combinations. For example, multilayer films allow a combination of different properties, such as an internal layer with approval for food contact and an external optimized for printing or moisture resistance.
