The paper presents heat transfer calculation results concerning a control rod of Forsmark Nuclear Power Plant (NPP). The part of the control rod, which is the object of interest, is surrounded by a mixing region of hot and cold flows and, as a consequence, is subjected to thermal fluctuations. The paper describes a numerical test which validates the method based on the solution of the inverse heat conduction problem (IHCP). The comparison of the results achieved by two methods, computational fluid dynamics (CFD) simulations and IHCP, including a description of the IHCP method used in the calculation process, shows a very good agreement between the methods.

The subject of the presented article is Bulgarian, Polish and Russian emotive verbs, treated in perspective of syntactic valence. The author examines the grammatical forms of propositional argument in the sentences with emotive verbs that represent pre- dicate-argument structure P (x, q). All forms are divided into several types: observance, compression and splitting. The author shows that in this area we have to deal with analog reflection of propositional structure, or more or less compression of proposition argument, or its dismemberment and doubling syntactic position. The author takes into account the regularity of the implementation of each grammatical form, quoting the relevant quantitative data.
