Opis:
Objective: We reviewed functional outcomes of tympanoplasty. Study design: The results of tympanoplastic surgery are changing in time. We present late treatment outcomes among different types of tympanoplasty. Methods: Eighty-six patients who underwent tympanoplasty were enrolled in the study. The results of pure tone audiometry performed 7 days before, then at 3 months, 1 year, and 3 years after the surgery were assessed. Type II tympanoplasty involved implantation of a partial ossicular replacement prosthesis and type III tympanoplasty involved reconstruction with a total ossicular replacement prosthesis and the use of autogenous homogenous material. Statistical analysis was performed. Results: With all four types of tympanoplasty, hearing improvement was achieved at 3 months and 1 year after surgery based on the magnitude of the mean ABG reduction (p<0.001). In patients who underwent type I, type III, and type IV tympanoplasty, the ABG reduction at 3 years after surgery was maintained at the level reported at 3 months and 1 year after surgery (p<0.001). In patients who underwent type II tympanoplasty, however, the mean ABG value was increased at all tested frequencies (p<0.05). The mean ABG values reported 3 years after type II and type III tympanoplasty were similar. Conclusions: Based on the results over time, hearing improvement seems to be less durable after reconstruction with the partial ossicular replacement prosthesis procedure compared to the total ossicular replacement prosthesis procedure.

Opis:
Aim. One of the challenges of the labour market in Poland is to match competences adequately to the needs of employers and to enable future employees, including students, to acquire these competences before they start their careers. The aim of the research was to answer the questions, which methods of developing competencies are known to the students, which are used by them and how do they assess their effectiveness. Methods. The research was carried out by mix-mode method, using quantitative (CAWI, N=352) and qualitative (IDI, N=10) surveys, and the respondents were students of the University of Lodz. Results. The results indicate that the best known and most commonly used methods of developing competencies are: individual self-education, classes at university, professional work, internships, apprenticeships, voluntary work, trainings, workshops, courses. As regards the evaluation of the effectiveness of the indicated methods of developing competencies, the students considered professional work to be the most effective method. Moreover, the results indicate that each of the methods of developing competencies may be effective, and the effectiveness depends on several factors. Conclusion. Therefore, it seems crucial not only for students to know and use various methods of developing competencies, but also for universities to ensure high quality activities, so that they effectively support the development of students' competencies and respond to the needs of the labour market.

Opis:
The subject of this publication is to determine the impact of biogas plants on the environment, with particular emphasis on greenhouse gasses emissions associated with the production and management of biogas as the main plant product. The environmental impact of the agricultural sector as well as the state of development of the biogas market in European Union are presented as background for consideration of greenhouse gas emissions. One of the economy sectors responsible for GHG emissions is agriculture. One of the solutions of GHG reduction in agriculture is slurry management using biogas technology. It should be emphasized, that biogas not always has favorable emission parameters. The final emission throughout the whole life cycle of this energy carrier depends on many factors. The structure of GHG emissions largely depends on what type of raw material it used for biogas production and in what kind of tanks the digestate sludge is stored. If waste raw materials are used for biogas production, then GHG emission associated with their acquisition is assumed to be zero. On the other hand, if dedicated energy crops are used for biogas production, the emission connected with cultivation of these plants are added to the total GHG emissions. They are directly related to the use of fertilizers and plant protection products, field emissions of nitrous oxide and fuel combustion during the operation of agricultural machinery. Influence on the GHG emission has also the kind id digestate storage tank. If these are closed tanks, there is no emissions to the atmosphere. If tank is open, then methane is emitted directly to the air and is included in the total GHG balance.

Opis:
Recycling of end-of-life passenger vehicles is a well-known topic, and there are many literary reports in this regard. However, little information is available on the recycling of bulky vehicles, which determines the authors’ intention to present this issue. This article describes the loopholes that have prevented end-of-life vehicles from currently being recycled.  The forms of recycling of these types of vehicles has been shown, and they are analogous to those for passenger cars. Also being presented are the causes of design changes in passenger cars and trucks, with the reasons for these changes being slightly different in bulky vehicles, than in passenger cars, and the article will discuss how these changes translate into recycling. Examples of actions taken by large vehicle manufacturers to meet the changes taking place in the economy, and implement the principles of the circular economy, in the field of recycling large-size vehicles, are also outlined.
Recykling pojazdów osobowych wycofanych z eksploatacji jest tematem znanym i w tym zakresie można znaleźć wiele doniesień literaturowych. Natomiast niewiele informacji jest dostępnych na temat recyklingu pojazdów wielkogabarytowych, dlatego intencją autorów było przedstawienie tego zagadnienia. W tym artykule opisano luki prawne, które spowodowały, że pojazdy wycofane z eksploatacji nie są obecnie objęte wymogiem recyklingu. Wykazano, jakie są formy recyklingu tego typu pojazdów i że są one analogiczne jak dla samochodów osobowych. Przedstawiono także, jakie są przyczyny zmian konstrukcyjnych w samochodach osobowych i ciężarowych, że przyczyny tych zmian są nieco odmienne w pojazdach wielkogabarytowych niż w osobowych i omówiono jak te zmiany przekładają się na recykling. Przedstawiono także przykłady działań podejmowanych przez dużych producentów pojazdów, które wychodzą naprzeciw zmianom zachodzącym w gospodarce i wdrażają zasady gospodarki o obiegu zamkniętym w zakresie recyklingu pojazdów wielkogabarytowych.
