Opis:: One of the most fundamental examination in intensive care medicine is cardiac output measurement, realized by pulmonary artery catherization. The thermodilution cardiac output estimation method is not resistant to various kinds of disturbances, which significantly decreases its sensitivity and specificity. The paper depicts investigations related to analysis of presumable new source of unreliability - asymmetric blood flow through pulmonary vessels. The investigations consisted of two phases: clinical examination (to obtain anatomical data) and computer modeling (to simulate the flow symmetry).

Opis:: The scope of an article that is presented below covers a preliminary analysis of a wireless link of ultrasound signal transmission in commercial radio frequency band (UHF). The radio link is used to transmit short ultrasound bat-like biosonar signals. Because of complicated structure properties and of transmitted signals the various methods of wireless transmission are shown. The hardware implementation consists of micro-electro-mechanical system microphone, microphone preamplifier and FM transmitter. At the end of the radio link a standard FM receiver is used. Since we use frequency modulation an influence of the radio link on received signal parameters is presented. The analysis of results provides us a set of information that might be used in designing of large scale wireless sensor networks for bats behavior monitoring.

Opis:: The reflection, absorption and scattering influence on turbid structure has been discussed. The influence of transverse scanning method on geometrical deformations as well as issues of thickness absolute measurements and refractive index evaluation methods has been analyzed. A number of phenomena which may be the artefact source and the cause of tomogram incorrect interpretation have been pointed out.
