Cord length

This calculation is tedious to perform for each particle of a distribution even with the advent of computer aided image analysis. Faster techniques simply measure a linear dimension parallel to some fixed direction and assume that the particles are oriented randomly so that these measurements average out when a sufficiently large population has been sized. Several linear dimensions typically are used. Ferefs diameter is the mean value of the distance between pairs of parallel tangents to the projected outline. Martin s diameter is the mean cord length of the projected outline of the particle. In addition, the maximum... 

Rounding up tower diameter D to 3 ft. Note that the diameter is small for trays as the tower is used for laboratory testing. Weir length L is the cord length in a circle, while weir width is the rise as shown in Figure 12.17. From geometry, there is a relationship between arc area (Aj), rise (the same as downcomer width Wd) and radius (r = D/2) ... 

The detonating cord length is usually 900 mm. The middle part of the detonating cord passes over a lead or aluminum plate, as illustrated in Figure 4.3. 

The name, number, and voltage of equipment controHed should be clearly marked on aH switch boxes, compensators, and starters. Pias and chains should be required on aH butterfly switches. Extension cords should be three-wire and limited to 8-m lengths. 

Linear Density. Linear density is defined as the weight per unit length (usually defined as denier), weight in grams of 9000 m or Tex, gram weight of 1000 m of yam or cord (26). Tex is often used as dTex (Tex x 10) and is related to denier because dTex = denier x 1.111. 

Stress in a Cord. Twisting two or more filaments together to form a cord reduces the overall modulus and strength of the constmction. The degree of the reduction depends on the individual filaments (55). If the lay length is significantly higher than the filament diameter, the stress is... 

Most portable vibration data collectors use a coiled cable to connect to the transducer (see Figure 43.24). The cable, much like a telephone cord, provides a relatively compact length when relaxed, but will extend to reach distant... 

The spinal cord is classically divided into white and grey matter (Fig. 21.2). The grey matter can be organised into ten different laminae, which run continuously along the entire length of the spinal cord. Within a given section of a spinal cord, each lamina can be seen as a layer of functionally distinct cells. Laminae I to VI comprise the dorsal horn, laminae VII to IX the ventral horn, and lamina X is the substantia grisea centralis which surrounds the central canal. 

Two types of OPIDN have been described in animals (Abou-Donia and Lapadula 1990). Type I is produced by compounds with a pentavalent phosphorus (like TOCP), and Type II is produced by compounds with a trivalent phosphorus. Characteristics used to differentiate between the types of OPIDN include species selectivity, age sensitivity, length of latent period, and morphology of neuropathologic lesions. Thus, at doses that did not produce death due to acetylcholinesterase inhibition, TOCP (a Type I compound) produced lesions in the spinal cord of rats without producing ataxia. In contrast, triphenyl phosphite (a Type II compound) produced delayed (1 week) ataxia in the rat and a distribution of spinal cord lesions distinct from those produced by TOCP (Abou-Donia and Lapadula 1990).
