Glass effect size

Two types of plastic panels [effective size, 0.6 x 1.0 m made from poly(vinyl chloride) resin] were used for testing the sheets in polluted areas. One is the open type (the sheets are exposed to air) and the other a windowed type. The open type can simulate realistic conditions. The windowed type has a Pyrex glass window that allows the UV light to reach the sheets. The roadside air was continuously pumped to the windowed panels at 15-60 1 min-1. This type was used for estimating the amount of air coming into contacted with the materials. The air purifying materials were attached to the panels using adhesive tape. 

Because such measures are particularly popular in meta-analysis, where in particular the effect size was used by Glass (1976) in his pioneering work, they will be dealt with in some detail in Chapter 16. Here, it will simply be mentioned that such measures are problematic when randomization, rather than random sampling, is the basis for inference. The patients in a clinical trial are not representative of some target population. In particular, depending on circumstances that vary from trial to trial - such as entry criteria, the centres in which the trial is conducted, the precision with which measurements are taken and a host of other factors - the standard deviation may be...

For the actual calculations the simplified model described above has to be extended. The main additional ingredient is the so called nucleation term which takes into account the more physical process of nucleation. By nucleation appear particles of a definite size by transformation of water soluble oligomers into particles. For another extension, taking into account the gel effect and the glass effect, see [8]. 

Filters may be grouped into two main types Hurd and Spencer, 1991). The pore sizes of depth filters are not well defined, and the separation reUes on physical trapping and surface contact. Generally, the thicker the filter, the smaUer the effective size of particle which passes through. The filter materials include cellulose, metal oxides or glass fibres (see Table 2-1 and Fig. 2-1.). The pore sizes of sieve filters are much better defined. They are made principally from plastic films e.g., polycarbonate (see Table 2-1 and Fig. 2-1). Some types (e.g., Nuclepore filters) have very well defined holes, but the amount of material which can be collected on these filters is normally lower than that recovered on the depth filters . It is also important to note that the effective pore size will change too as more and more particles accumulate on the filter.

Particle Size and Electrical Properties. The effect of glass particle size on sheet resistance of a model thick-fihn resistor is shown in Fig. 8.68 for various conductive phase concentrations. The effects of glass particle size are more pronounced at low conductive phase concentrations. The effect of conductive phase particle size on electrical properties of thick-fihn resistors was studied by several researchers." "" For a given volume fraction of conductive phase, smaller particle sizes will decrease the sheet resistance and render the TCR more positive.
