Heat release in glasses at low temperatures

Physical Review B, 1993
The long-time heat release in glasses after cooling a sample from some initial temperature ${\mathit{T}}_{1}$ to ${\mathit{T}}_{0}$ has been calculated in the framework of the soft-potential model. It is shown that there are three temperature regions where time and temperature dependences of the heat release are different.

Mediator release in local heat urticaria

Journal of Allergy and Clinical Immunology, 1981
We described the sixteenth reported case of local heat urticaria, in a 59-yr-old woman with erythema and angioedema upon contact with hot water or outdoor heat exposure. Immersing her hand in 39 degrees to 40 degrees C heated water resulted in an erythematous, angioedematous response sharply demarcated by the line of immersion and was associated with ...

Heat-released stress in acrylic dentures

The Journal of Prosthetic Dentistry, 1979
Dimensional changes in an acrylic resin denture blank that are sufficient to cause changes in fit on a gypsum cast occur primarily when the dentures are heated in water to a temperature of 90 degrees C or more. The poor correlation between observed fit and the intermolar distance change indicates that the dimensional change of dentures is much more ...

Heat Release in Solids

1998
In this chapter we will discuss two consequences of the tunneling model that is used to understand the low-temperature properties of amorphous and disordered solids: a time-dependent specific heat and the corresponding time-dependent heat release. This “heat release” (often referred to as “energy relaxation”) is the warming-up effect observed in a ...

Refinement of Heat Release Analysis

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">The refinement of heat release analysis stems from the recognition that a combustion system is intrinsically non-linear. Thus, as appropriate for such an entity, its properties are expressed in terms of a thermochemical phase (or state) space, of which the thermodynamic aspects are exposed on a so-called Le ...

Heat release kinetics

Fire and Materials, 2000
The role of solid-state thermal degradation kinetics in steady-flaming combustion is examined. Expressions for the burning surface temperature, pyrolysis zone depth and fractional mass loss rate are derived from heat transport limited, nonisothermal pyrolysis kinetics.

Heat transfer in enclosures with programmed heat release

Journal of engineering physics, 1982
The problems of calculating the indoor air temperature, heat consumption, and room temperatures with arbitrary thermal perturbations are examined.

Anthropogenic Heat Release Into the Environment

Volume 6: Energy, Parts A and B, 2012
This work is intended to systematically study an inventory of the anthropogenic heat produced. This research strives to present a better estimate of the energy generated by humans and human activities, and compare this estimate to the significant energy quantity with respect to climate change.

Heat release in the reactor core

2009
Chapter 1 contains introductory information about the heat release in the reactor core, the thermal power and thermal power density in the fuel, structures and moderator, the influence of the thermal power density on the coolant temperature, and the spatial distribution of the thermal power density.

Heat Release in Indirect Injection Engines

2009
The rate of heat release in an in direct injection engine is modelled on the lines of the observed rate in a direct injection engine. The premixed burning is assumed to take place only in the prechamber. The diffusion burning was modelled to be proportional to the modelled rate of air entrainment and available fuel.
