The Caloric Theory of S. L. Metcalfe
The British Journal for the History of Science, 1984Samuel Lytler Metcalfe (1798–1856) was an American chemist and physician who wrote a voluminous work, Caloric Its Mechanical Chemical and Vital Agencies in the Phenomena of Nature (2 vols., London, 1843); attempting to account for all natural phenomena in terms of caloric.

Journal of Thermal Analysis and Calorimetry, 2009
Abstract The works of Lazare and Sadi Carnots are reviewed emphasizing their contribution to the caloric theory of heat, which is consequently analyzed in terms of an alternative thermodynamic approach. In the framework of the caloric theory the elementary derivation of the efficiency of real heat engines, ηK=1−tr(T 2/T 1), is given which is a direct ...

Chaos Theory Applied to the Caloric Response of the Vestibular System
Computers and Biomedical Research, 1993Developments in the field of nonlinear dynamics has given us a new conceptual framework for understanding the mechanisms involved in the regulation of complex nonlinear systems. This concept, called "chaos" or "deterministic chaos," has been applied to EKG, EEG, and other physiological signals, but not yet to the ENG signal.

Toward a unified theory of caloric restriction and longevity regulation
Mechanisms of Ageing and Development, 2005The diet known as calorie restriction (CR) is the most reproducible way to extend the lifespan of mammals. Many of the early hypotheses to explain this effect were based on it being a passive alteration in metabolism. Yet, recent data from yeast, worms, flies, and mammals support the idea that CR is not simply a passive effect but an active, highly ...

Studies in History and Philosophy of Science Part A, 1994
Abstract I began this study with Laudan's argument from the pessimistic induction and I promised to show that the caloric theory of heat cannot be used to support the premisses of the meta-induction on past scientific theories. I tried to show that the laws of experimental calorimetry, adiabatic change and Carnot's theory of the motive power of heat ...

The British Journal for the History of Science, 1970
Research on thermal “black-body” radiation played an essential role in the origin of the quantum theory at the beginning of the twentieth century. This is a well-known fact, but historians of science up to now have not generally recognized that studies of radiant heat were also important in an earlier episode in the development of modern physics: the ...

Fluid Phase Equilibria, 1986
Abstract A thermodynamic model is presented in which the “perturbed hard chain theory” is combined with the “chemical theory”. The equation of state so obtained permits the description of the thermodynamic properties not only of systems containing nonpolar or polar substances, but also of systems containing carboxylic acids. The determining factor is

Heat Engines and the Caloric Theory of Heat
1996This chapter will present an alternative route to the thermodynamics of simple fluids at a slightly higher mathematical level, allowing for a generalization of the subject of thermodynamics of uniform fluids. The most important difference to the previous development has to do with what we assume to know about the nature of heat.

Controversies on the caloric response:From Bárány's Theory to Studies in Microgravity
Acta Oto-Laryngologica, 1990Two objections against Robert Bárány's scientific contributions are reviewed. Firstly the Medical Faculty in Vienna raised the question as to whether Bárány really could be credited with the initial discovery of the caloric reaction in man and whether therefore it was justified to have awarded him the Nobel Prize in 1914.

Calorimetry and the Caloric Theory of Heat, the Measurement of Heat
2019Joseph Black distinguished between the quantity of heat in a body and its intensity, or temperature, which was introduced in Chap. 1. This chapter introduces calorimetry, the measurement of the quantity of heat, and the contemporary theory of heat, the caloric theory of heat.
