Thermodynamics with Internal State Variables

The Journal of Chemical Physics, 1967
This is a study of the thermodynamics of nonlinear materials with internal state variables whose temporal evolution is governed by ordinary differential equations. After employing a method developed by Coleman and Noll to find the general restrictions which the Clausius—Duhem inequality places on response functions, we analyze various types of ...

Hysteretic Systems with Internal Variables

Journal of Engineering Mechanics, 2001
Hysteretic rate-independent constitutive laws are introduced within the framework of continuum thermodynamics with internal variables and revisited using concepts and arguments related to dynamical system theory. The evolution of internal variables is formulated either by a system of differential equations or by the associated phase flow.

Dual Internal Variables

2017
It is shown how dual weakly non-local internal variables and extra entropy fluxes can be introduced in the framework of canonical thermomechanics on the material manifold. This extension of the single internal variable formalism allows one to derive a hyperbolic evolution equation for internal variables in the non-dissipative case.

Variability in hand hygiene practices among internal medicine interns

American Journal of Infection Control, 2013
Hand hygiene compliance remains suboptimal among physicians despite quality improvement efforts. We observed hand hygiene compliance among 29 medicine interns at 2 large academic institutions. Overall compliance was 75%. Although 4 interns averaged

Dynamically variable internal symmetries

Journal of Mathematical Physics, 1981
The mathematical consequences of the ansatz that the generators of internal transformations, as well as the parameters, may be space–time-dependent is investigated. In addition to the Yang–Mills type fields, a transformation changing field must be introduced. The formalism developed is consistent.

Tropical Atmospheric Variability Forced by Oceanic Internal Variability

Journal of Climate, 2007
Abstract Atmospheric general circulation model experiments are conducted to quantify the contribution of internal oceanic variability in the form of tropical instability waves (TIWs) to interannual wind and rainfall variability in the tropical Pacific.

International Variability in Childlessness

Journal of Family Issues, 1982
This article provides a descriptive account of international trends and variability in marital childlessness. Childlessness data, gathered largely from census questions on number of children ever born, are presented for 65 countries. In discussing trends in childlessness, we introduce several procedures for measuring childlessness that are closely ...
