[Tools and methods of developing educational programs in medical biophysics].

In this work various types of programs which can be used in a learning and teaching process are analysed. Also the procedure of creating software for CAL is studied and the procedure, that is the most suitable one for developing CAL is suggested here. Also recommended properties of software for teaching and learning medical biophysics are described. General characteristics and types of authoring tools are discussed in this work and a set of authoring tools is described in more details. Conclusions are documented and demonstrated by program Blood Circulation. For development of this program the authoring system Authorware 3.5 was selected. The program is organized as a hypertext with possibility to find words, with a list of the last visited pages, and with an on line help system. This program works with a text, graphics, interactive animated schemes and with interactive equations. In the program it is possible to test the level of knowledge by means of solving problems or multiply choice test.

[Use of thermoelectric properties of materials with shape memory in medicine].

Article deals with some possibilities of the combination of the shape memory and another physical properties of nitinol (Ti-Ni alloy) for application in the medicine. The thermoelectric properties of originally developed miniature thermocouple probe with the shape memory are described in details. The shape memory effect of the thermocouple is based on the use of the combination of the metals nitinol and constantan.

Technical note: Parasitic thermovoltage in the multithermocouple probe, its explanation and elimination.

The parasitic thermovoltage can influence the temperature measurement during hyperthermia using the miniature multithermocouple probes with a common wire. It was noticed that, when a thermocouple junction is placed in a sharp thermal gradient, a parasitic thermovoltage is added to the voltage of all remaining thermocouples situated in the direction to the tip of the probe. This article gives the theoretical explanation, experimental verification, and practical elimination of this phenomenon.
