Dimension measuring devices are also necessary to control width and thickness of extrudates for most applications. In many cases it is also necessary to check weigh cut to length rubber sections. 

The fractal dimension measures how open or packed a structure is lower fractal dimensions indicate a more open system, while higher fractal dimensions indicate a more packed system (22). Theories relating the fractal dimension to the relaxation exponent, n, have been put forward and these are based on whether the excluded volume of the polymer chains is screened or unscreened under conditions near the gd point (23). It is known that the excluded volume of a polymer chain is progressively screened as its concentration is increased, the size of the chain eventually approaching its unperturbed dimensions. Such screening is expected to occur near the... 

Figures 2 through 9 are design charts for ultraviolet stabilized polycarbonate under blast load. Charts are provided for pane thicknesses of 1/4, 3/8, 1/2, and 1 inch for pane areas up to 25 ft at pane aspect ratios (pane length to width ratios) of 1.00, 1.50, 2.00 and 4.00. The charts relate the peak experienced blast overpressure capacity, B, for convenient pane dimensions across the spectrum of encountered blast durations. Depending on the orientation of the window to the charge, the blast overpressure may either be incident or reflected. The pane dimensions (measured across the span from the gasket centerline) peak blast capacity at 1000 msec, B, static frame design pressure, r, and the required bite are printed to the right...

The Nobel laureate Richard P. Feynman described, in a lecture delivered in 1959, the future of miniaturization. The published version of his lecture is called There s Plenty of Room at the Bottom and in it can be found a recipe for putting the entire Encyclopedia Britan-nica on the very small head of a very small pin. Feynman s comments set into motion an entirely new area of study and have lead to what have become known as the fields of nanoscience and nanotechnology. Chemists, physicists, materials scientists, and engineers have come together over the past several decades to produce with high accuracy and precision materials that have dimensions measured in nanometers (nm, 10 meters, about 1/100 000 the width of a human hair). Specifically, materials with one, two, or three dimensions of 100 nm or less (called, respectively, nanofilms, nanotubes, and nanoparticles) qualify as products of nanotechnology. It appears that almost any chemical substance that is a solid under ordinary conditions of temperature... 

The corrected structural parameters of benzotriazole obtained from microwave spectroscopy are shown in Figure 6 <93JSP(161)136>. For comparison, the molecular dimensions measured by x-ray of crystalline benzotriazole-1-carboxamide <93ACS167> and 2-aminobenzotriazole, as an example of a 2-substituted benzotriazole, are listed in Figure 6 <90JCS(P2)237>.

Molecular dimensions measured by X-ray diffraction show that several boron containing rings are close to planarity and that many bond lengths are intermediate between single and double bonds. However, no monocyclic unsaturated boron heterocycle has so far been subjected to this kind of investigation.

Diffractometer software can search for reflections, measure their precise positions, and subsequently compute unit-cell parameters. This search entails complexities we need not encounter here. Instead, I will illustrate the simplest method for determining unit-cell dimensions measuring reflection spacings from an orthorhombic crystal on a precession photograph.

The reliability of the experimental procedure (deformation in the melt, quenching, characterization of orientation at room temperature) could be verified in elongation (specimens quenched for different macroscopic extensions in steady elongational flow) as well as in simple shear (good correlation of the chain dimensions measured in all principal shear directions).

Concerning some counted algae species, linear dimension measurements were performed, using a special measuring grid on the ocular of the microscope.
