The effect of elevation of body temperature on the electroretinogram of the rat was investigated in the dark-adapted state. A systematic decline in latency was noted as the body temperature was raised stepwise from 37 to 41 degrees C, averaging 1.9 ms degrees C-1. Maintenance of animals at a body temperature of 41 degrees C or greater led initially to(More)
According to both cybernetics and general system theory, a subject develops and uses an adequate model of a system to widen his/her knowledge about the system. Models are then the interface between a subject and a real-world system to solve problem and to construct knowledge. Hence, evaluating these models is crucial to ensure the quality of the constructed(More)
This paper presents a study of the absorption of electromagnetic waves in the human head while using a mobile phone. This absorption is presented in the form of thermal effects of exposure to radiofrequency electromagnetic fields for long period or in the form of non-thermal effect for short period exposure. We therefore present the levels of absorption of(More)
The body temperature was raised stepwise in rats to determine its effect on brain stem auditory evoked potentials. The underlying aim was to examine whether the resultant changes in evoked potentials could be used to predict both the regional temperature and functional state of the brain stem. Such data are likely to be of benefit in cases where(More)
