Medical applications of model based dynamic thermography
The proposal to use active thermography in medical diagnostics is promising in some applications concerning investigation of directly accessible parts of the human body. The combination of dynamic thermograms with thermal models of investigated structures gives attractive possibility to make internal structure reconstruction basing on different thermal properties of biological tissues. Measurements of temperature distribution synchronized with external light excitation allow registration of dynamic changes of local temperature dependent on heat exchange conditions. Preliminary results of active thermography applications in medicine are discussed. For skin and under- skin tissues an equivalent thermal model may be determined. For the assumed model its effective parameters may be reconstructed basing on the results of transient thermal processes. For known thermal diffusivity and conductivity of specific tissues the local thickness of a two or three layer structure may be calculated. Results of some medical cases as well as reference data of in vivo study on animals are presented. The method was also applied to evaluate the state of the human heart during the open chest cardio-surgical interventions. Reference studies of evoked heart infarct in pigs are referred, too. We see the proposed new in medical applications technique as a promising diagnostic tool. It is a fully non-invasive, clean, handy, fast and affordable method giving not only qualitative view of investigated surfaces but also an objective quantitative measurement result, accurate enough for many applications including fast screening of affected tissues
Tissue engineered heart valves for transcatheter aortic valve implantation: current state, challenges, and future developments

The measurement of product placement
Product placement can be defined as utilisation of a real product or a service directly in audiovisual works, under clear, contractually-agreed terms. The methodology for measuring the effectiveness of funds invested in product placement in audiovisual works has not been developed yet. The authors of this paper propose a possible solution for measuring the effectiveness of product placement, which they applied in the Vinari (Winemakers) TV series. The authors proceeded from the price. A sponsor of a TV commercial would have to pay to reach the target group to the same extent as when using product placement. The CPP (Cost per Point) approach was used, i.e. the cost of reaching 1% of the target group. Reaching the target group was surveyed by means of a primary investigation of the perception of the sponsor's company as a financial backer of cultural activities by using questionnaires. The authors based their calculations of effectiveness regarding the sponsoring of a television series using elements of brand and product placement on a model calculation of the current advertising prices for a thirty-second advertising spot in relation to the CPP. The average recall of the product placement in the sponsored series represented 16% of the target group. It was calculated that if broadcasting TV spots, the price would be CZK 6.7 million, which is more than six times the amount of the value of the sponsorship. The survey shows that there are positive benefits related to the support of the Vinari (Winemakers) TV series. A significant fact is also that respondents were still able to recall this sponsorship even after several days and not only when this information actually reached them. No pricelist or media can guarantee that a communicated message will be recalled, so sponsorship in TV series is concluded to be highly effective for reasonable price and with prolonged effect which surpass advertising expectations. © Institute of Society Transformation, 2016
Practical experience in and improvements to aerosol sampling for trace analysis of airborne radionuclides in ground level air
In November 1989 the Polish government and the German government signed a bilateral agreement for scientific and technological co-operation. In the framework of this co-operation the Central Laboratory for Radiological Protection (CLRP), Warsaw, and the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, conducted a co-operation project in the field of monitoring the airborne radioactivity in ground level air. This progress report deals with the history of the project covering the period from July 1990 to December 1992, the scientific activities and their results. A proposal for future co-operation, which is planned for the near future, is made.
