capacity

 [kah-pas´ĭ-te]
the power to hold, retain, or contain, or the ability to absorb; usually expressed numerically as the measure of such ability.
closing capacity (CC) the volume of gas in the lungs at the time of airway closure, the sum of the closing volume and the residual volume. See also closing volume.
decreased intracranial adaptive capacity a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as the state in which intracranial fluid dynamic mechanisms that normally compensate for increases in intracranial volumes are compromised, resulting in repeated disproportionate increases in intracranial pressure in response to a variety of noxious and nonnoxious stimuli.
diffusing capacity see diffusing capacity.
forced vital capacity the maximal volume of gas that can be exhaled from full inhalation by exhaling as forcefully and rapidly as possible. See also pulmonary function tests.
functional residual capacity the amount of gas remaining at the end of normal quiet respiration.
heat capacity the amount of heat required to raise the temperature of a specific quantity of a substance by one degree Celsius.
inspiratory capacity the volume of gas that can be taken into the lungs in a full inhalation, starting from the resting inspiratory position; equal to the tidal volume plus the inspiratory reserve volume.
maximal breathing capacity maximum voluntary ventilation.
thermal capacity heat capacity.
total lung capacity the amount of gas contained in the lung at the end of a maximal inhalation.
 Subdivisions of total lung capacity: TLC, total lung capacity; V, tidal volume; IC, inspiratory capacity; FRC, functional residual capacity; ERV, expiratory reserve volume; VC, vital capacity; RV, residual volume. From Dorland's, 2000.
virus neutralizing capacity the ability of a serum to inhibit the infectivity of a virus.
vital capacity (VC) see vital capacity.

The difference between molar isobaric heat capacity ([C.sub.p]) and molar isometric heat capacity ([C.sub.v]) for gases is the ideal gas constant (R).
The heat capacity with a fixed charge can be calculated as
Heat Capacity. According to the experimental method, the heat capacity [C.sub.p] of Li[B.sub.5][O.sub.8] x 5[H.sub.2]O was measured using the adiabatic calorimeter from 297 to 375 K with standard uncertainty 0.05 J x [mol.sup.-1] x [K.sup.-1], and the result of the molar heat capacity of Li[B.sub.5][O.sub.8] x 5[H.sub.2]O is shown in Table 2 and Figure 3.
As far as we are aware, this is the first QSPR study for prediction physicochemical properties such as the heat capacity (Cv), thermal energy and entropy of natural amino acids using topological indices.
A practicable computational alternative, however, requires the availability of a duly elaborate analytical framework for the inverse relationship, which should hence enable performing straightforward evaluations of the actual [x.sub.D] (T) = [[THETA].sub.D](T)/T-ratios directly on the basis of given heat capacity values, [C.sub.p] (T).
To express the HDH heat capacity in the form of the criterion P-function Q(L,d,P,t) the following four private functions of one argument heat capacity have been selected:
Also since the article focusses on the temperature of the core and poles, and all heat dissipation occurs in poles and core, and because they have the highest contribution to the total heat capacity of a cell, the Biot number should be calculated as the ratio of heat conduction inside the core to the conduction outside the core.
Our primary goal was to determine how the heat capacity of plywood and oriented strand board (OSB) sheathing varies with moisture content (MC) between oven-dry and about 18 percent, dry basis.
Shell thermal properties were estimated by running multiple computational fluid dynamic (CFD) simulation iterations, varying the thermal conductivity and heat capacity over a range of values in an effort to fit the calculated cooling curves to the experimental cooling curves for the shell and casting.
Table 2 shows heat capacity and latent heat of fusion values as well as some generic processing and ejection temperatures for common materials.
