Doughnut

The intensity of the vertically polarized scattered light is proportional to sin 0 which, in polar coordinates, is described by a figure 8-shaped curve centered at the origin and having maximum values of 1 at 0 = 90°, Because 0 is symmetrical with respect to the z axis, this component of scattered light is described in three dimensions by a doughnut-shaped surface in which the hole has shrunk to a point - centered symmetrically in the xy plane. 

The horizontal component is identical except for its orientation in space. In the horizontal case the doughnut lies in the xz plane.

Used in baked goods (breads, cakes, cookies, crackers, doughnuts), pasta products, emulsified and coarsely ground meat products, meat analogues, breakfast cereals, dietary foods, infant foods, confections, milk replacers, and pet foods. 

Many other products belong to the category of yeast-raised bakery foods (6—9). Some that may be cited include various kinds of specialty breads, coffee cakes and danish pastries, bagels, croissants, yeast-raised doughnuts, some types of crackers, English muffins, and roUs. Of the total annual sales of the baking industry, yeast-raised goods constitute about 61%. 

Dielectric Constant The dielectric constant of material represents its ability to reduce the electric force between two charges separated in space. This propei ty is useful in process control for polymers, ceramic materials, and semiconduc tors. Dielectric constants are measured with respect to vacuum (1.0) typical values range from 2 (benzene) to 33 (methanol) to 80 (water). TEe value for water is higher than for most plastics. A measuring cell is made of glass or some other insulating material and is usually doughnut-shaped, with the cylinders coated with metal, which constitute the plates of the capacitor. 

Refer to Fig. 15-39. The tower is formed into compartments by horizontal doughnut-shaped or annular baffles, and within each compartment agitation is provided by a rotating, centrally located, horizontal disk. Somewhat similar devices have been known for some time. The features here are that the rotating disk is smooth and flat and of a diameter less than that of the opening in the stationaiy baffles, which facihtates fabrication and apparently improves extraction rates. The typical proportions of the internals of the RDC are as follows ... 

Under the hghtest winds, the air rises over the warmest part of the urban core, drawing cooler air from all directions from the surroundings (Fig. 17-21). Subsidence replaces this air in rural areas, and a closed torus (doughnut)-shaped circulation occurs with an outflow above the urban... 

Fi re 3.9 Schematic diagram of the structure of one domain of a bacterial muramidase, comprising 450 amino acid residues. The structure is built up from 27 a helices arranged in a two-layered ring. The ring has a large central hole, like a doughnut, with a diameter of about 30 A.

Although these baffles can be as effective as the segmental ones for single-phase heat transfer, they are not used as often. The fluid must be clean otherwise sediment will deposit behind the doughnut and blank off the heat transfer area. Also, if inert or dissolved gases can be released, they cannot be vented effectively through the top of the dough-...

The bottom section of the main column provides a heat transfer zone. Shed decks, disk/doughnut trays, and grid packing are among some of the contacting devices used to promote vapor/liquid contact. The overhead reactor vapor is desuperheated and cooled by a pumparound stream. The cooled pumparound also serves as a scrubbing medium to wash down catalyst fines entrained in the vapors. Pool quench can be used to maintain the fractionator bottoms temperature below coking temperature, usually at about 700°F (370°C). 

What do orbitals look like There are four different kinds of orbitals, denoted s, p, d, and f] each with a different shape. Of the four, we ll be concerned primarily with s and p orbitals because these are the most common in organic and biological chemistry. The s orbitals are spherical, with the nucleus at their center p orbitals are dumbbell-shaped and four of the five d orbitals are doverleaf-shaped, as shown in Figure 1.3. The fifth d orbital is shaped like an elongated dumbbell with a doughnut around its middle.
