    Opis:
    The aim of the paper is to investigate the effectiveness of the 18K380 steam turbine condenser air extraction system using hydro ejectors. Motivation for the analysis was a need of improvement of the energy conversion ratio of the power plant. To achieve this goal it was necessary to establish efficiency of each subsystem of the energy cycle. The air extraction system is not a highly power consuming system but it has great impact on the steam cycle efficiency by influence on the condensation temperature. The air extraction system effectiveness depends on a weather conditions, exactly on the ambient temperature, which raises the question whether it is worth to modernize the hydro ejectors or replace them by a centrifugal vacuum pumps. To establish the vacuum system effectiveness a new innovative mass flow measuring system has been implemented to measure an air-steam mixture flow and the fraction of the air mass in the mixture. The measuring system is based on a Venturi nozzle supplemented with a temperature drop during the mixture expansion.

    Opis:
    Purpose: In the article, the kinetic growth phenomena of aluminide coating formed by plasma spraying pure Al-Si powder and subsequent diffusion annealing on TiAl intermetallic alloy in inert atmosphere were investigated. Design/methodology/approach: The Al-Si powder was thermal sprayed (APS) on TiAl7Nb intermetallic alloy and annealed in Ar atmosphere during 5, 15, 30, 60, 240 and 480 min. The kinetic growth of the coating was observed using the scanning electron microscopy method (SEM), and chemical composition was analysed using the EDS method. Findings: The Kirkendall Effects pores formation, as well as titanium silicides on the grain boundary of TiAl3, was found. Research limitations/implications: The oxidation resistance of the developed coating might be analysed in further work. Practical implications: The developed coating might be used for the production of protective aluminide coatings on TiAl intermetallic alloys. Originality/value: The description of aluminide coating formation in a new technological process.

    Opis:
    Contemporary medicine should provide high quality diagnostic services while at the same time remaining as comfortable as possible for a patient. Therefore novel non-invasive disease recognition methods are becoming one of the key issues in the health services domain. Analysis of data from such examinations opens an interdisciplinary bridge between the medical research and artificial intelligence. The paper presents application of machine learning techniques to biomedical data coming from indirect examination method of the liver fibrosis stage. Presented approach is based on a common set of non-invasive blood test results. The performance of four different compound machine learning algorithms, namely Bagging, Boosting, Random Forest and Random Subspaces, is examined and grid search method is used to find the best setting of their parameters. Extensive experimental investigations, carried out on a dataset collected by authors, show that automatic methods achieve a satisfactory level of the fibrosis level recognition and may be used as a real-time medical decision support system for this task.

    Opis:
    The aim of the research was to determine level and sources of dietary fiber (DF) in daily nutrition intake among teenage girls (16–18 age) from Szczecin. According to recommended level of DF, determined average level was much lower and comprised of 45.6% of daily requirements. Source and amount of DF in composite ration were as follows: cereal products 38% and vegetables with fruits 38%. Moreover, content of energy, proteins, carbohydrate, fat and cholesterol were additionally determined in order to compare with dietary guidelines. All stated above elements were present in insufficient quantity and did not correspond to current nutritional guidelines (mean percentage ranged form 54.2 to 80.4%).

    Opis:
    One of the greatest challenges of nature conservation is to identify and locate networks of protected areas, which will preserve the biodiversity. The paper aims to show the ornithological value of the Sobibór Forests (E Poland) and to emphasize the fact that the network of Important Bird Areas (IBA) and Special Protection Areas within Natura 2000 (SPA) may require additions. The study was conducted in the period of 2008−2016, mainly on forested areas occupying 256 km2. The Sobibór Forests are characterized by a large diversity of habitats, but are mainly covered by Scots pine Pinus sylvestris. High diversity of wetlands and marshlands make the Sobibór Forest unique within the country. Three methodologies were used to estimate population size of chosen species: sampling, census and random observations. 31 species from Annex I of the Birds Directive plus 25 species of SPEC or non−SPECE category were observed which allows to consider this area as one of the most valuable for avifauna in Poland. Six breeding species classify the Sobibór Forests as the IBA and SPA. These species include Black Stork Ciconia nigra (8−13 breeding pairs), Common Crane Grus grus (80−120 breeding pairs), Grey Great Owl Strix nebulosa (0−7 breeding pairs i.e. 50−100% of Polish breeding population), Eagle Owl Bubo bubo (6 breeding pairs), White−backed Woodpecker Dendrocopos leucotos (40−70 breeding pairs) and Grey−headed Woodpecker Picus canus (20−40 breeding pairs). Six other species show potential for qualification, but not enough data has been collected yet. The list of this specie includes: Short−toed Snake Eagle Circaetus gallicus, Common Snipe Gallinago gallinago, Stock Dove Columba oenas, European Nightjar Caprimulgus europaeus, Collared Flycatcher Ficedula albicollis and Bluethroat Luscinia svecica. The Sobibór Forests occupy a small area compared to other IBA forests. However, the number of breeding species classifies the surveyed area as 7th among other IBAs. Moreover all eligible species may be considered as a bioindicators of the natural state of the forest. This is proof of the high natural value of this area.
