In this topic review the results of the X-band electron paramagnetic resonance (EPR) measurements of Mn, Co, Cr, Fe ions in YAlO3 (YAP) crystals and Fe ions in LiNbO3 (LNO) crystals and of chromium doped Bi12GeO20 (BGO) and Ca4GdO(BO3)3 single crystals, are presented. It is well known that the oxide crystals (for example:YAP, LNO, BGO) are one of the most widely used host materials for different optoelectronic applications. The nature of point defect of impurities and produced in the oxide crystal after irradiation by bismuth ions and after irradiation by the 235U ions with energy 9.47 MeV/u and fluency 5 × 1011 cm−1 is discussed. The latter is important for applications of these oxide crystal as laser materials.
Szargut proposed the algorithm for determination of the influence of irreversibility of components of thermal process on the emission of CO2 [6]. In the presented paper, basing on Szargut's proposal, the example of analysis of influence of operational parameters of coal fired power plant on the local increase of CO2 emission is presented. The influence of operational parameters on the local exergy losses appearing in components of investigated power plant are simulating making use of the semi-empirical model of power plant.
In this paper, the author derives theoretical formulae for calculating of squeezing forces. This report is the first one concerning the method of forming stepped shafts by longitudinal cold rolling. The formulae of the radial squeezing forces for the final passage of longitudinal rolling were calculated under the Huber hypothesis of plastic deformation and maximum shear stress.
The Historical-Philosophical Faculty of the Academy of Arts and Sciences, including its Committee on History, was involved in very intensive scholarly and editorial activity. Among the many institutions which broadly cooperated with the Academy, one can indicate the Kórnik Library. The scholars representing the Lviv and Cracow academic circles composed the dominant group of those who conducted their research in the Kórnik Library. The impressive source editions, initiated by the Academy, were significantly based on the Kórnik collections. The scholars were interested in those sources dealing mainly with history of the Polish state and nation, the history of its law, literature, religion and warfare. The cooperation between these two institutions also included making excerpts, copying and answering to the requests of the scholars, as well as exchanges of various publications. As an addition, the Kórnik Library offered a whole collection of its own publications to the Cracow researchers. The mutual contacts were often based on personal friendship and can be considered as an example of friendly academic cooperation being utilised to fulfil a common task. No doubt this cooperation contributed to the development of Polish academia, enriching the status of research on the history of Poland, enabling numerous source editions and monographs as well as helping to maintain the direct contacts between Polish scholars living and working in various parts of the Polish lands under Austrian and German occupation at the turn of the twentieth century.
