The major surfactant families in use in the European market in volume terms are the non-ionics followed by anionic derivatives. A detailed breakdown of the total surfactant consumption for Western Europe can be found in Tables 1.6 and 1.7, which show the estimated proportions for the various uses of surfactants in the European market. Probably the most important final use of surfactants in Europe is in detergent manufacture, as demonstrated by the figures summarised in Table 1.8. 

In addition to the implementation process, evaluation of the project s success is the core of a restoration project. However, many projects do not take this final check, which is a prerequisite for adaptive management, into consideration. Bernhardt et al. [23] found that only 10% of project records (out of 37,099 projects) indicated that any form of assessment or monitoring was carried out. In most European countries, the estimated proportion of success evaluation is in the same range or even lower. Project evaluation through systematic data collection serves to verify whether the project objectives that were defined during the planning phase have been achieved [24]. Therefore, project evaluation is the process of examining the...

As mentioned in Chapter 1, ethylene is always the more reactive olefin in systems used to produce copolymers involving a-olefins (LLDPE and VLDPE). An important process consideration for copolymerizations is the reactivity ratio. This ratio may be used to estimate proportions needed in reactor feeds that will achieve the target resin. However, fine tuning is often required to obtain the density or comonomer content desired. Reactivity ratios were discussed previously (Chapter 2) in the context of free radical polymerization of ethylene with polar comonomers. Reactivity ratios are also important in systems that employ transition metal catalysts for copolymerization of ethylene with a-olefins to produce LLDPE. Discussions of derivations and an extensive listing of reactivity ratios for ethylene and the commonly used a-olefins are provided by Krentsel, et al. (1).

For example, if 25 participants received treatment A and, among them, 5 reported a headache, the estimated proportion of participants reporting a headache is 5/25 = 0.20, which can also be expressed as 20%. When such an analysis is repeated for all AEs reported, and the quantities are expressed as percentages and displayed in tabular form in a package insert, it is relatively easy for prescribing physicians and their potential patients to answer their questions.

Plastics account for only about 11.3 percent of materials in the U.S. MSW stream by weight (Fig. 8.4), but this proportion continues to increase. The proportion by volume is very difficult to determine accurately, but is certainly larger than the percent by weight, as the density of plastics is less than the average of MSW. EPA in the past has estimated proportion by density only for the portion of the waste stream going to disposal (landfill and incineration), reporting that plastics acconnted for 26.1 percent of discarded MSW by volume in 1997, when their proportion was 13.0 percent by weight. ... 

Accordingly, it seems to be more realistic to interpret the variation in the C NMR chemical shifts of membrane proteins in terms of the dynamics-dependent displacement of peaks as a novel means of probing the dynamic aspect of membrane proteins. Therefore, the transmembrane a,i-helix could be ascribed to a residue whose time-averaged deviation of torsion angles at ambient temperature differs from that of static ones at low temperatures, arising from the presence of a low-frequency motion associated with a local anisotropic fluctuation. It is interesting, however, to note that the estimated proportion of the (Xii-helix on the basis of the carbonyl C chemical shift is much smaller when compared with that observed for the Ala Cp as in the case of Ala 14, 53, and...

Table 6.1 shows fluxes for metals from mines, emission to atmosphere, transportation by rivers, and removal by rainwater. Most of anthropogenic metals transported to atmosphere are taken up by rainwater. However, this is unclear because fluxes to the atmosphere are not only by human activity but also by namral process such as volcanic activity and estimated proportion of these two processes has large uncertainty. Riverine fluxes to ocean are mostly larger than anthropogenic fluxes to atmosphere and fluxes by rainwater, but anthropogenic fluxes to atmosphere for toxic metals (Pb, Hg, Se, As, and Sb) are considerably large. 

The proportions of each component have to be derived from the fitting model which does describe the Mossbauer spectra recorded at different temperatures, for different grinding times and milling conditions. It is clearly established that the evolution of the crystalline component decreases when the grinding time increases at the expense of the grain boundaries whereas the estimated proportions are found to be rather similar to those estimated from X-ray diffraction patterns, assuming spherical grains. 

Figure 11-5. Estimated proportion of drivers killed as a function of vehicle deformation, crash type, and driver alcohol consumption. Solid bars indicate alcohol involved drivers. Type 1 accident is angle, rear-end, or other single vehicle type 2 is overturn, head-on, or hit fixed-object. Vehicle deformation is rated on a 7-point scale with 1 being the least damage and 7 being the most (From Waller et al, 1986, with permission from the American Medical Association).

Bacillariophyceae, or diatoms, are extremely widespread in the marine environment, and constitute the greatest proportion of the phytoplankton (95-98%). Thus, they are responsible for most of the oceanic photosynthesis, although benthic species also exist. The diatoms are also found in great quantities in freshwater and other aquatic and semi-aquatic habitats. An estimate of the number of species is about 100000, and the estimated proportion of marine species varies from 30% to 50%. Hence, there would be between 30 000 and 50 000 species of marine diatoms (Armbrust, 2009).
