Separable profiles

A mixture of powdered poly(vinyl chloride), cyclohexanone as solvent, silica, and water is extruded and rolled in a calender into a profiled separator material. The solvent is extracted by hot water, which is evaporated in an oven, and a semiflexible, microporous sheet of very high porosity ( 70 percent) is formed [19]. Further developments up to the 75 percent porosity have been reported [85,86], but these materials suffer increasingly from brittleness. The high porosity results in excellent values for acid displacement and electrical resistance. For profiles, the usual vertical or diagonal ribs on the positive side, and as an option low ribs on the negative side, are available [86],...

The general separation behavior can be seen from the shape of the velocity profiles (Fig. 5.8). For the stable flows, the curvature of the velocity profiles is everywhere negative. As the outflow Reynolds number increases, the velocity gradient at the wall decreases, eventually leading to an inflection in the velocity profile. Separation occurs at this point, with the solution jumping to a combination of inflow and outflow. 

We see differences in the cuticular hydrocarbon profiles of reproductive and non-reproduc-tive individuals across species and insect families. The questions are how the patterns differ and whether there are any general patterns at all. This section demonstrates the huge variety in the kind of differences we see. No compound class exists that could generally reflect differences in fertility, nor does a specific pattern in the composition of a profile separate reproductive from non-reproductive individuals. The only pattern that may emerge relates to the reproductive potential of individuals, colony size and queen-worker dimorphism. 

For biopharmaceuticals, quantitative monosaccharide profiling allows detection of residues indicative of undesired glycosylation (e. g. NeuGc) or the classes of glycans (for example, the presence of GalNAc indicates 0-glycosylation). For technical reasons, neutral and A-acetylat-ed residues are generally profiled separately from sialic acids. 

When auditing a site or a plant, we rely on clearly defined criteria to produce an environmental and safety profile. Separate audits are conducted to determine the occupational health conditions at a facility. A site s performance profile covers both hard facts such as accident numbers and emission levels, as well as soft facts such as effective organizational structures, defined responsibilities, and a... 

Ion implantation is well suited for the design of bipolar structures used in injection logic. Among the attributes of ion implantation for these are 1) ability to fabricate shallow devices thus improving the speed and gain and tailoring the impurity concentration profiles. Separate implantations for the inactive and the active base layers are usually desirable.

A better approach is to consider the individual time-temperature intervals of the given time-temperature profiles separately, and to use a weighted evaluation of these intervals regarding their contribution to the aging process in the component [104]. This procedure is analogous to the degradation accumulation hypothesis by Miner s rule, Eq. 1.7. 

A specialty pectin, which is used as a fat substitute, is a partially methylated polygalacturonic acid. Pectins from different sources have different oligogalacturo-nic acid profiles. Separation of pectins of various DPs is possible using AEC with an acetate gradient. 

In Sections 4-6 and 4-17 we discussed light-acceptance properties of fibers illuminated by a diffuse source by considering the power entering bound rays. Here we examine the power entering leaky rays and its variation along the fiber. For convenience we consider step and graded profiles separately. 

When considering the example risk profiles separately, it is uncomplicated to identify that they do have several connections with each other. Therefore, when combining the causes and effects of several risk factors, it is possible to determine the coimections among several actors in the value network. By this way it is possible to illustrate the larger and more complex risk stmctures like the map in Fig. 3.4. The example influence map illustrates the cause and effect relationships between elements in an industry system. An arrow represents a positive relationship implying that element x increases the element y , and vice versa. Similarly, a negative relationship is illustrated by an arrow with a minus symbol indicating that when element x increases the element y decreases, and vice versa.
