Uses of cnclii,sinj> murks. The formula for the entire coordination enlily. whether charged or not. is enclosed in square brackets. When ligands are polyatomic, their formulae are enclosed in parentheses. Ligand abbreviations are also enclosed in parentheses. In the special case of coordination entities, the nesting order of enclosures is as given [on page A-5I. There should be no space between representations of ionic species within a coordination formula. 

The quantum theory was originally proposed by Planck in 1900 to explain the emission spectrum of a heated enclosure or black body. On the assumption that radiation was emitted dis-continuously he was able to develop a semi-theoretical formula... 

In Eq. (5-118), SS and SG are defined as the required arrays of total surface-to-surface exchange areas and total gas-to-surface exchange areas, respectively. The matrices for total exchange areas are calculated explicitly from the corresponding arrays of direct exchange areas and the other enclosure parameters by the following matrix formulas ... 

The Two-Zone Enclosure Figure 5-18 depicts four simple enclosure geometries which are particularly useful for engineering calculations characterized by only two surface zones. For M = 2, the reflectivity matrix R is readily evaluated in closed form since an explicit algebraic inversion formula is available for a 2 X 2 matrix. In this case knowledge of only E = 1 direct exchange area is required. Direct evaluation of Eqs. (5-122) then leads to... 

The following formulas permit the calculation of F, from requisite direct exchange areas. For the special case where the enclosure is divided into any number of black source-sink zones, Mb > 2, and the remainder of the enclosure is lumped together into a single refractory... 

This formula, due to Einstein, was experimentally verified by Jean Perrin 94) by direct microscopic observation of spherical colloidal mastic particles (with radius 6.5-10 cm), which contained. small enclosures of impurities on the surface, thus permitting their rotary motion to be directly followed. 

The formulae given here can be derived from the mass balance (see enclosure 2). For this model the reciprocal values of the formaldehyde concentration are plotted along the Y-axis of a graph and the corresponding airflow, eventually devied by the volume -the so called ventilation rate - is plotted along the X-axis. 

Aerosol packaging has played a smaller role in this area than in others like furniture polishes, air fresheners, and hair care. It has survived most often when a thick foam meant to stick to vertical surfaces is needed as in the case of oven cleaning or bathtub enclosures. In future it can be expected that as packaging innovation continues, specialized formulas will be matched to them to create more convenient and targeted cleaning systems for consumers to use. 

The thermodynamical proof of the Stefan-Boltzmann law rests on the existence of radiation pressure. We imagine an enclosure shut off by a movable piston with a reflecting surface. The radiation field exerts a pressure on the piston its magnitude is a function of u, the energy density of the radiation in the enclosure. In fact, both Maxwell s theory and the quantum (corpuscular) theory of light give the formula... 

Combining the two expressions of the number of mode of vibration with the average energy of vibration and reported to the volume of the enclosure of blackbody, results the expression of the density of spectral energy, as Rayleigh-Jeans formula (RJ)... 

Caulking compound (liquid polymer poly sulfide synthetic rubber formula 112 for metal enclosures)... 

A formula is available that considers the proximity or the eccentricity of a conductor enclosed within a conducting-pipe enclosure [24] that is, a PT cable [20,38]. However, there is no formula that considers the proximity between two conductors above the earth.
