Concentric circumferences

Subsequently, we suspected the duct s grid system to be positioned at 3,60m. We, therefore, concentrated our tests on these areas. At all new positions tested elear echo-signals were found (see Scans in Fig. 8). This resulted in 7 ducts localized around the circumference. In most cases the drilling instantly hit the duets, heneeforth all duets were found. 

Summary of Characteristics of Falling Film Continuous SOj Sulfonation Processes. Both concentric and multitubular reactor systems suppHed by competing manufacturers have surprisingly similar operating characteristics organic feedstock loading of ca 0.4 kg/(h-mm) (circumference) for LAB, and ca 0.3 kg/(h-mm) for alcohol ethoxylates an SO concentration of 3.3—5.0 vol % SO for LAB sulfonation, and 2—3% SO ... 

The band structure of four concentric armchair tubules with 10, 20, 30, and 40 carbon atoms around their circumferences (external diameter 27.12 A) was calculated, where the tubules were positioned to minimize the energj for all bilayered pairs 17). In this case, the four-layered tubule remains metallic, similar to the behavior of two double-layered armchair nanotubes, except that tiny band splittings form. 

The graphical integration method is based on graphical presentation of the average flow profile. For a circular duct, the cross-section is virtually divided into several concentric ring elements. The spatial mean velocity of such an element is determined as an arithmetical mean of local velocities along the circumference of the corresponding radius. For a circular cross-section the flow rate can be expressed as... 

Reducers Reducers may be cast, forged, or hot- or cold-formed from pipe or plate. End connections may be concentric or eccentric, that is, tangent to the same plane at one point on their circumference. For pipe supported by hangers, concentric reducers permit maintenance... 

A bum is very serious with reserved prognosis when ischemia spreads on more than half of the limbal circumference (Fig. 7.6). Most of the times, this ischemia predominates on the lower half of the limbus, because it is where the chemical, in general a liquid, concentrates. It is necessary to emphasize that the maximum quantity of liquid which can cover the surface of the eye is 200 pL. 

One of the simplest and earliest methods for the measurement of decay times was due to Becquerel (58). His instrument consisted of two disks mounted concentrically on a rotating shaft. Each disk contains a slit, or sector, cut into the circumference, and the sample to be studied is placed between the disks. The slits act as two shutters. The first opens to illuminate the sample, and the second permits the fluorescent light to exit to a detector. 

Note that the integral is terminated at the cutoff distance R0/ 2 in order to avoid a singularity. The vacancy concentration at a distance from the loop appreciably greater than Rl can now be found by treating the loop itself as an effective point source made up of all the point sources on its circumference. The number of these sources is 2ttRl/R0, and therefore... 

An acid-leached polyethylene terephthalate (Mylar) sheet was placed inside the circumference of the centrifuge bowl to enable rapid recovery of trapped particles. Particles and lake water (4 L), retained in the centrifuge bowl after the selfsealing device isolated the bowl, were recovered and kept at 4 °C for transport to the laboratory. Time delay from the collection to laboratory processing varied from 24 to 36 h. At typical lake-water particle concentrations of 1 mg/L, more than 0.5 g of suspended particles could be collected in 1 h. On-station time limited the number of large-volume depths sampled per cruise to six or seven. The depths chosen were selected to be representative of distinct layers of the water column and also to correspond to depths at which sediment traps were deployed.
