Opis:
W artykule przedstawiono wyniki badań tribologicznych pary trącej "głowa-panewka" stanowiącej układ ruchowy endoprotezy stawu biodrowego, o średnicy głowy 44 mm. Zarówno głowa, jak i panewka zostały wykonane ze stopu CoCrMo. Badania przeprowadzono na symulatorze SBT-01 przy dwóch różnych kątach ustawienia panewki względem kierunku docisku głowy. Przedstawiono zależności momentu tarcia, siły docisku od kąta obrotu, porównano zużycie elementów oraz wartości pracy tarcia i temperatury dla obu zakresów kątowych. Pracę wykonano w Laboratorium Inżynierii Powierzchni i Tribologii Instytutu Obróbki Plastycznej w Poznaniu.
The article presents the results of tribological results of friction couple "head-cup" which is the system hip replacement, with a diameter of ?44 mm head. Both the head and the cup are made of CoCrMo alloy. The study was conducted on the simulator SBT-01 at two different cup rotation angle ranges to the head. The relations of moment of friction, normal load from the angle of rotation, compared to the wear and work of friction valuesand temperature ranges for both angle ranges. The work was performed at the Laboratory of Surface Engineering and Tribology in Metal Forming Institute in Poznan.

Opis:
As a result of research conducted in the Metal Forming Institute in Poznan, SBT-03 simulator for friction and wear testing of human intervertebral disc endoprostheses was modernized. The structure of the device allows reflecting of the range of mobility and loads present in the natural spine. Moreover, the device allows recording and measurement of such parameters as axial compression force, moment of friction, temperature in the friction loop and number of operation cycles. This enables an evaluation of the intensity of wear processes of different designs of structures of a lumbar spine intervertebral disc endoprostheses depending on the type of materials used and production method.

Opis:
Simulator based training has its own unique features and problems associated with it. There is a need to discuss these issues in order to understand the real meaning of simulator based training and to handle it effectively. Like other fields of training, use of simulation in the maritime industry is owing to the multiple factors covering technological, financial and training needs of the time. When properly used, supported by well trained and experienced instructors, simulator training, through its risk free environment, can contribute to a reduction in accidents and improve capability and efficiency, by providing trainees with the necessary experience and self confidence to carry out their roles, functions and tasks.

Opis:
Traditional concept of seafarers’ training was based upon theoretical teaching in class room followed by the practical training onboard ship. This concept underwent profound changes in 80s due economic and practical reasons emanating from new face of the marine industry. Simulator based training had obvious advantages of being economical, safe and redundant. But it had its own implications as well. How perfect a simulator may be, it still was far away from real ship experiences. Instructor became more and more important and he is actually responsible to connect up the simulator experience with real ship experiences through his visualization and does not let the trainee get into a discourse or fall into a game mood. This study examines how the importance of simulator instructor is on the rise and present tools available for the qualification of the simulator instructors need to be augmented with new measures so as to ensure the quality of the simulator based training of the seafarers.

Opis:
Goal – the author analyzes the special provisions of modern migration law of the Russian Federation, which regulate the special procedure for visiting the Kaliningrad region. The attention of the author focuses on the study of Russian migration legislation amendments, which significantly liberalized the migration procedure for foreign citizens visiting the Kaliningrad region on a short-term basis by introducing electronic visas (e-visa) valid merely for a particular subject of the Russian Federation. Research methodology – in this paper, the author uses the traditional methods of scientific research, such as analysis, induction, deduction, as well as logical and historical-legal methods. The author also undertakes a formal legal analysis of relevant provisions of federal law and current issues of legal practice in the Kaliningrad region. Score/results – based on the analysis of the federal migration legislation, which simplifies the legal regime for visiting the Kaliningrad region by e-visas, the author concludes that this legal mechanism of the migration policy of modern Russia plays an important role in the economic development of this region of the Russian Federation. In addition, the author draws attention to the fact that electronic visas can also contribute to the development of scientific and educational cooperation between higher education institutions of the Kaliningrad region and their foreign partners. In particular, this migration mechanism can be actively used in order to improve the cooperation between the Immanuel Kant Baltic Federal University with international partners in the framework of multiple projects, including “The Border University Network” (BUN), “The Baltic Sea Region Universities Network” (BSRUN), and other important international network projects in the field of higher education and science. Originality/value – the article contains original conclusions on improving the legal mechanism of electronic visas used when foreign citizens visit the Kaliningrad Region. Namely, the author expresses his suggestions on permanently maintaining the charge-free nature of these e-visas for visits of the Kaliningrad Region, as well as relaunching small border traffic (SBT) between the Kaliningrad region and the Republic of Poland (with selected Polish border areas (voivodships).
