SOME CONDITIONS THAT SIMULATE CHRONIC APPENDICITIS.*1

Normal Models that Simulate Dysfunction

Response of compressed skinned skeletal muscle fibers to conditions that simulate fatigue.

During fatigue, muscles become weaker, slower, and more economical at producing tension. Studies of skinned muscle fibers can explain some but not all of these effects, and, in particular, they are less economical in conditions that simulate fatigue. We investigated three factors that may contribute to the different behavior of skinned fibers. 1) Skinned fibers have increased myofilament lattic...

Reflective Simulation - Simulation of Systems That Simulate

The paper is dedicated to simulation of intelligent systems that “imagine” their possible future states by medium of simulation models handled by some of their elements. The reason and importance for simulation of such systems, the techniques for implementing their “nested” simulation models and the obstacles related to the implementation are described and some applications are presented.

[Chronic alcoholism and antisociality: examination of some socioeconomic conditions].

In this report the Authors are concerned with the important phenomenon of a number of alcohol addicts being present in most psychiatric hospitals. This phenomenon is viewed on the social and economic background which in characteristic of the Lecce psychiatric hospital (a background marked by notable migratory movements, massive industrialisation, chaotic urbanisation, etc.). A particular emphas...

Simulate heart rate variability in different physiological conditions.

Heart rate variability is assumed to result from a multiplicative or cascade mechanism based on its multifractal property. Numerical results on the perturbation of the cascade are given to compare HRV under parasympathetic (PNS) and sympathetic (SNS) autonomic blockades. It was found that qualitative change of the HRV multifractal, which was observed in PNS blockade, is due to the change from a...
