The article presents the results of the research on thermal actions on the materials occurring in the cross section along the depth of the bridge deck and bituminous pavement during its construction. The impulse to curried out the research was the need to explain the causes of the blistering of bituminous waterproofing membranes and asphalt pavements often observed on the bridge decks. The paper presents the examples of such failures and the analyses of possible mechanisms of the phenomenon. Research indicates a significant influence of all technological processes on the temperature of materials in the cross section as well as daily temperature changes. The probability of initiation of reactions between concrete components with gaseous products has been confirmed in such conditions. The susceptibility of bituminous materials to gas emission and blistering is the subject of a separate study. The research was part of a research project carried out under the contract INNOTECHK3/IN3/50/229332/NCBR /14 [13].

The article presents detailed two-phase adiabatic pressure drops data for refrigerant R134a. Study cases have been set for a mass flux varying from 200 to 400 kg/m2s, at the saturation temperature of 19.4°C. Obtained experimental data was compared with the available correlations from the literature for the frictional pressure drop during adiabatic flow. Influence of mixture preparation on pressure drop was investigated, for varying inlet subcooling temperature in the heated section. The flow patterns have also been obtained by means of a high-speed camera placed in the visualization section and compared with literature observations.

Joseph Ratzinger binds together the triptych “theology – the university – science” by the common issue of a search for the truth and the service to the truth. Theology is being done “in the Church and with the Church”, it belongs to the Church and depends upon her. Thus, theology is ecclesial in its essence, it teaches not in its own name but on behalf of the Church.

The ethos of the university – particularly of a Catholic university – consists in the common witness to the truth and in forming the transcendent dimension of man. Thus, the service to the human person is expressed by the university in developing “a new humanism” as a response to cultural and spiritual desires of the humankind. The mission of the university is not only its service to knowledge but also to the education, which means bearing witness to the truth that has been found.

According to Benedict XVI both theology and the university with science should know how to unite the two ways of knowing – faith and reason into one common tone, with its unique enhancing of reason. In a characteristic way Ratzinger gives special attention to rationality which leads to the ultimate Truth.
