However, synthetic fibers (cellulosic and noncellulosic) increased much more rapidly in importance, with cellulosics booming between World Wars I and II and noncellulosics dominating after World War II, while all that time cotton showed only a steady pace in comparison. The more recent competition between the various fibers in the United States is given in Fig. 17.1. Nylon was originally the most important synthetic (1950-1971) but polyester now leads the market (1971-present). For a few years (1970-1980) acrylics were third in production, but since 1980 polyolefins have been rapidly increasing. Polyolefins are now second only to polyester in synthetic fiber production. Cotton, being an agricultural crop, certainly demonstrates its variable production with factors such as weather and the economy. It is an up-and-down industry much more so than the synthetics. 

International Homicide Comparisons. Guncite.com. Available online. URL http //www.guncite.com/gun control gcgvinco.html. Updated on October 18, 2003. Discusses the difficulty of drawing valid homicide comparisons between the United States and other countries, and alleged misuse of such data by gun control supporters.

In the crystal structure of the polymer phase (Fig. 17a), the polymer chains are aligned along the c-axis and the distance (3.71 A) between the centres of adjacent cyclobutane and pyrazine rings corresponds to half the c-axis repeat of the unit cell. For comparison between the monomer and polymer structures, an overlay plot of these structures is shown in Fig. 17b. It is clear that the solid-state reaction is associated with only very small atomic displacements at the site of the [2-1-2] photocyclization reaction (the displacement of the carbon atoms of the C=C double bonds of monomer molecules on forming the cyclobutane ring of the polymer is only ca. 0.8 A for one pair of carbon atoms and ca. 1.6 A for the other pair). Such small displacements are completely in accord with the assignment of this solid-state reaction as a topochemical transformation [124—127] (in which the crystal structure of the reactant monomer phase imposes geometric control on the pathway of the... 

The relationships developed from field measurements have been made dimensionless with the assumptions that v = 1.33 x 10 m /s and AijO = 2.6 x 10 m /s to facilitate comparisons between relations and avoid dimensional problems. They are given in Table 9.2. The early measurements were to investigate the loss of water from the reservoirs of the Colorado River in the United States, and the later measurements were designed to investigate heat loss from heated water bodies. A revelation occurred in 1969, when Shulyakovskyi brought in buoyancy forces as related to natural convection to explain the heat loss from heated water at low wind velocities. This was picked up by Ryan and Harleman (1973), who realized that natural convection could explain the need for a constant term in front of the relationship for gas film coefficient, as had been found by Brady et al. (1969), Kohler (1954), Rymsha and Dochenko (1958), and Shulyakovskyi (1969). Finally, Adams et al. (1990) rectified... 

We performed a detailed comparison of the economic scale of radiation use in the fields of industry [4], agriculture [5], and medicine [6] in Japan and the United States. The comparison between Japan and the United States was also done for an economic index regarding market creation of products obtained from use of both radiation and nuclear energy [7]. The results of our study are compared for the year 1997. 

The economic scale is compared between the United States and Japan with selected industrial parameters such as sterilization, semiconductors, radiographic testing, and radial tire production, because the very large industrial markets make a whole comparison difficult. The economic scale revealed in selected industrial fields was about 56 billion for the United States and 39 billion for Japan. The former is larger by a factor of — 1.4 [4].

Carpenter et al. (1988) carried out a nested case-control study of cancer of the central nervous system among workers at two nuclear facilities located in Tennessee (United States). They identified 89 cases (72 males and 17 females) who had died between 1943 and 1979. Four controls, living at the time the case was diagnosed, were matched to each case. Job history records were scrutinized by an industrial hygienist to assess potential exposure to each of 26 chemicals or chemical groups. Toluene, xylene (see this volume) and 2-butanone (methyl ethyl ketone) were evaluated as one chemical group the matched relative risk was 2.0 (95% confidence interval (Cl), 0.7-5.5 n = 28) in comparison with unexposed workers. Almost all cases had had low exposure, according to the classification used and there was no dose-response trend. The authors stated that the relative risks w ere adjusted for internal and external exposure to radiation. 

Data enabling comparisons of the compositional differences of sedimentary zeolites of different origin are scarce. Such comparisons have been mostly between zeolites from magmatic rocks and those from sedimentary rocks, independent of the genetic type of the latter (1). The studies of Coombs and Whetton (2), which compared the specific features of analcime in metamorphic and unaltered sedimentary rocks, are evidence of the capabilities of this approach. Clinoptilolites belonging to different groups—alkaline basins of the United States (la), true sedimentary rocks...
