i·so·vol·u·mic

(ī'sō-vol-yū'mik),
Occurring without an associated alteration in volume, as when, in early ventricular systole, the muscle fibers initially increase their tension without shortening so that ventricular volume remains unaltered.

Within the frame of the harmonic lattice regime, the temperature dependencies of the isochoric heat capacities, [C.sub.Vh] (T), are well known to be given by corresponding heat capacity shape functions, [[kappa].sub.h] (T), of the general form [4, 6, 45, 50-55]
This condition is satisfied since the isochoric heat capacity of the multicomponent system is positive.
A minority of hemangioma may present as an isochoric or hypoechoic mass relative to the liver parenchyma.
The results of the physical examination showed that the patient's arterial tension (TA) was 130/70 mm Hg, pulse was 78/min, temperature was 36.2C, her Glasgow Coma Score (GCS) was (E4M6V5) 15, pupils were isochoric. Neurological examination did not demonstrate any abnormities.
where v = n - 2, n = 1 + [[GAMMA].sub.V][infinity], [[GAMMA].sub.V][infinity] is the isochoric Gruneisen coefficient [2], and [??], [beta], and [sigma] are parameters.
Only the measurable isobaric heat capacity data [C.sub.P]([P.sub.0], T) have to be added to the set of input data for prediction of other caloric properties (isochoric heat capacity [C.sub.V](P,T), speed of sound W(P,T), and Gruneisen parameter Gr(P, T)) at higher pressures P > [P.sub.0] and lower T < [T.sub.m] or higher T > [T.sub.b] temperatures where [T.sub.b] is the hypothesized normal boiling temperature [T.sub.b]([P.sub.0]).
In the neurological examination, pupils were isochoric with no light reflex bilaterally, and the Glasgow Coma Scale Score was 4 ([E.sub.1][M.sub.2][V.sub.1]) intubated.
They showed that when the heat generation rate is low, the Boussinesq condition of isochoric flow and heat transfer is approximated.
Concerning the neurological examination, the patient was alert, oriented to place and person, with a Glasgow of 15/15, isochoric and isoreactive pupils with no evidence of localization, muscle strength of 5/5, preserved sensitivity and with a global ROT 2/4.
In the undeformed state B = 1, the identity tensor and m = [square root of 3]; otherwise, m > [square root of 3] for all isochoric deformations [8].
On physical examination; she was agitated, confused, disorientated and uncooperative; her pupils were isochoric, papillary light reflex: +/+.
For calculation purposes it is accepted that during initial compression in individual volume parts, adiabatic compression and isochoric heat transfer (5) can be expressed as:
