Opis:
In this paper, the authors determined the specific features of the construction of budgets in Poland and Norway and showed areas of tourism occurrence in the budget classifications of both countries. Then, thoroughly analysed the expenditures made by municipalities and counties of the Lodz region, booked in the financial accounts which content was strongly connected with tourism. Authors had focused on direct relationship, as well as indirect effects on the development of tourism through promotion, development of culture and sport. The obtained results were compared with corresponding values observed in the Norwegian county of Oppland and its municipalities. It should be emphasized that by completing the research project, authors gained knowledge to identify strengths and weaknesses of the of local budgets in Poland and Norway. Flexibility of classification and the high comparability of local government units\\\' budgets at all levels are the main advantages of Polish budgets. On the other hand, the precise description of budgets and high quality of official statistics are undoubtedly advantages of Norwegian local government budgets. The fact is that the resources available to the Norwegian local authorities, even after taking into account the difference between purchasing power of the Norwegian krone and Polish zloty, are objectively higher. It is worth noting that the amount of funds allocated to finance specific activities, such as those related to the development of tourism, cannot be equated with the efficiency of their spending. However this question was not the subject of research undertaken by the authors. Described research project gives the authors the ability to assess the position of tourism in the Polish and Norwegian budget classification. Although the Polish classification revealed a dedicated account that was directly connected with tourism, at the same time it was diagnosed to have minor importance in planning and constructing local budgets. Therefore, the problem with both Polish and Norwegian budgets is the lack of possibilities to perform simple estimations of the amount of resources assigned to the areas of tourism development. The authors suggest to perform a specific study within this range and develop a diagnosis of individual tasks financed by the government and determine the degree of their impact on the development of tourism in the municipalities or counties. Therefore they hope that this article will be a contribution to make further research on the importance of tourism in local government budgets.

Opis:
The present paper is the result of the investigations of the properties and structure of nanocrystalline layers deposited from iron-based nanoalloy on steel S355N substrate by manual metal arc welding method (MMA). In the process of welding a 100 A current intensity was used with desiccation preheating at 80°C while maintaining the interpass temperature at range of 200°C. The resultant deposit welds were subjected to macro and microscopic metallographic examination, X-ray phase analyses and crystallite size was analyzed by X-ray diffractometry (XRD), additionally EDX chemical composition analysis of precipitates during scanning electron microscopy was performed. Working properties of the obtained nanocrystalline deposit welds were evaluated based on hardness and metal-to-mineral abrasive wear. The results of the deposit welds working properties measurements were compared with the properties of wear resistant steel HARDOX 400 type used as the reference material.

Opis:
The paper presents the influence of ZrO2 coating on Ti6Al7Nb titanium alloy depending on the method of deposition. The coatings were made by sol-gel method and atomic layer deposition (ALD). Wettability tests, pitting corrosion assessment and electrochemical impedance spectroscopy (EIS) were carried out in the paper. Complementary macro- and microscopic observations, roughness analysis by profilometric method and atomic force microscopy (AFM) were made. Based on the results obtained, it can be concluded that the type of method of depositing the layer on the surface of the material has a significant influence on its properties and that it should be taken into account during the process of the material improvement. Drawing on the findings presented, it can be inferred that roughness has a significant impact upon the surface wetttability of the tested surfaces and their related corrosion resistance. The obtainment of hydrophobic surfaces is for smaller rougidity values.

Opis:
Artykuł określa wpływ lokalizacji i znaczenia węzłów transportowych, przebiegu sieci drogowej na rozmieszczenie centrów logistycznych. Analiza oparta była na danych dotyczących istniejącej i aktualnie rozwijanej sieci drogowej o znaczeniu regionalnym, krajowym i międzynarodowym. Dzięki zrealizowanym badaniom możliwe było wskazanie, w jakim zakresie rzeczywiście uwzględniono wagę węzłów sieci transportowej oraz międzynarodową i lokalną politykę transportową w dotychczasowych decyzjach lokalizacyjnych. Pod względem metodycznym udało się wskazać lokalizacje optymalne. Przede wszystkim udało się jednak ocenić podjęte dotąd decyzje lokalizacyjne, w tym wskazać znaczenie różnych determinant owych decyzji. Na podstawie uzyskanych wyników autorzy sformułowali uniwersalne rekomendacje dotyczące rozwoju regionalnej sieci transportowej. Realizacja tematu wynikała z badań podjętych przez autorów na zlecenie Urzędu Miasta Łodzi. Badania dotyczyły charakterystyki i kierunków rozwoju intermodalnych centrów logistycznych w kontekście funkcjonowania Transeuropejskich Sieci Transportowych (TEN-T) w województwie łódzkim, a w szczególności w Łódzkim Obszarze Metropolitalnym.
The main focus of the paper is to indicate the impact and significance of the location of transport hubs and road’s network for the location of logistics centres. The analysis was based on existing and constructed roads’ (regional, national and international level) data. Therefore, it was possible to determine the influence of the transport hubs, international and local transport policy on previous location decisions. Authors identified optimal locations of logistic centres in the Łódź region. Furthermore, authors assessed the location decisions and their determinants. Finally, universal recommendations for the development of the regional transport network have been formulated. This work was partially founded by the Municipality of Łódź. The study focused on the characteristics and trends of development of intermodal logistics centres in the context of the operation of the Trans-European Transport Network (TEN-T) in the Łódź region, particularly in the Łódź Metropolitan Area.

Opis:
The paper presents the results of the properties of flame sprayed ceramic coatings using oxide ceramic materials coating of a powdered aluininiuni oxide (Al2O3) matrix with 3% titanium oxide (TiO2) applied to unalloyed S235JR grade structural steel. A primer consisting of a metallic Ni-Al-Mo based powder has been applied to plates with dimensions of 5X200X300 mm and front surfaces of ø40x50 mm cylinders. Flame spraying of primer coating was made using a RotoTec 80 torch, and an external coating was made with a CastoDyn DS 8000 torch. Evaluation of the coating properties was conducted using metallographic testing, phase composition research, measurement of microhardness, substrate coating adhesion (acc. to EN 582:1996 standard), erosion wear resistance (acc. to ASTM G76-95 standard), and abrasive wear resistance (acc. to ASTM G65 standard) and thermal impact. The testing performed has demonstrated that flame spraying with 97% Al2O3 powder containing 3% TiO2 performed in a range of parameters allows for obtaining high-quality ceramic coatings with thickness up to ca. 500 μni on a steel base. Spray coating possesses a structure consisting mainly of aluminium oxide and a small amount of NiAl10O16 and NiAl32O49 phases. The bonding primer coat sprayed with the Ni-Al-Mo powder to the steel substrate and external coating sprayed with the 97%Al2O3 powder with 3% TiO2 addition demonstrates mechanical bonding characteristics. The coating is characterized by a high adhesion to the base amounting to 6.5 MPa. Average hardness of the external coating is ca. 780 HV. The obtained coatings are characterized by high erosion and abrasive wear resistance and the resistance to effects of cyclic thermal shock.

Opis:
Selective Laser Melting (SLM) is a modern manufacturing method with many applications in medicine, aerospace and auto-motive industries. SLM processed materials are characterized by good dimensional accuracy and properties comparable or superior to materials obtained by traditional processing methods. In this paper an SLM process was used to obtain 316L stainless steel parts. This paper presents the microstructure, chemical and phase composition, physicochemical and electrochemical properties of 12 groups of tested samples, differentiated by the SLM processing parameters. Based on the investigation, it can be inferred that the selection of the appropriate SLM parameters is very important to determined final material properties. The samples producedwith the energy density E = 600 J/mm3 were observed to possess optimum properties - a homogeneous structure, density closest to the desired one, good wettability and pitting corrosion resistance.

Opis:
The introduction of new reinforcing materials continues to be investigated to improve the final behaviour of AMCs as well as to avoid some drawbacks of using ceramics as reinforcement. The present work investigates the structure, properties and ability of joining aluminium EN-AW 6061 matrix composite materials reinforced with Ti3Al particles by resistance butt welding as well as composite materials produced by mechanical milling, powder metallurgy and hot extrusion techniques. Mechanically milled and extruded composites show finer and better distribution of reinforcement particles, which leads to better mechanical properties of the obtained products. Finer microstructure improves mechanical properties of obtained composites. The hardness increases twice in the case of mechanically milled composites also, a higher reinforcement content results in higher particle dispersion hardening, for 15 wt.% of intermetallics reinforcement concentration composites reach about 400 MPa UTS. Investigation results of joints show that best hardness and tensile properties of joints can be achieved by altering soft conditions of butt welding process e.g. current flow time 1.2 s and current 1400 A. To improve mechanical properties of butt welding joints age hardening techniques can also be used.

Opis:
The aim of this work is to determine the effect of manufacturing conditions, especially milling time, on the microstructure and crystallite size of a newly developed nanostructural composite material with the aluminium alloy matrix reinforced with halloysite nanotubes. Halloysite, being a clayey mineral of volcanic origin, is characterized by high porosity and large specific surface area. Thus it can be used as an alternative reinforcement in metal matrix composite materials. In order to obtain this goal, composite powders with fine microstructures were fabricated using high-energy mechanical alloying, cold compacting and hot extrusion techniques. The obtained composite powders of aluminium alloy reinforced with 5, 10 and 15 wt% of halloysite nanotubes were characterized with SEM, TEM and XRD analysis. It has been proven that the use of mechanical alloying leads to a high degree of deformation, which, coupled with a decreased grain size below 100 nm and the dispersion of the refined reinforcing particles–reinforces the material very well.
Celem niniejszej pracy było określenie wpływu warunków wytwarzania, w szczególności czasu mielenia, na strukturę i wielkość krystalitów nowo opracowanych nanostrukturalnych materiałów kompozytowych o osnowie stopów aluminium wzmacnianych nanorurkami haloizytowymi. Haloizyt, będący minerałem ilastym pochodzenia wulkanicznego, charakteryzuje się dużą porowatością, dużą powierzchnią właściwą, i może stanowić alternatywne wzmocnienie metalowych materiałów kompozytowych. W tym celu przy użyciu wysokoenergetycznego mechanicznego stopowania w młynie kulowym wytworzono rozdrobnione i trwale połączone proszki kompozytowe, które następnie poddano zagęszczaniu na zimno i wyciskaniu na gorąco. Tak opracowane materiały kompozytowe o udziale masowym haloizytowego wzmocnienia 5, 10, 15% zbadano metodami skaningowej i transmisyjnej mikroskopii elektronowej oraz rentgenowskiej analizy fazowej. Stwierdzono, że wywołane mechanicznym stopowaniem silne odkształcenie plastyczne i zmniejszenie rozmiaru ziarna poniżej 100 nm oraz dyspersja haloizytowych cząstek wzmacniających wpłynęła na znaczne umocnienie materiałów kompozytowych.

The aim of the study was to develop reference values for such haematologic values as haemoglobin concentration, haematocrit value, volume of erythrocytes, thrombocytes, leucocytes, lymphocytes, neutrophils, basophils, eosinophils and monocytes in peripheral blood in Polish mixed-breed rabbits, considering the impact of the season (spring, summer, autumn, winter), and sex of the animals. The results reveal, that the season of the year has a small impact in Polish mixed-breed rabbits, and it principally referred to spring and summer. Finally it was shown, that sex has average impact on the studied values of haematological parameters.

In studying this indices we took into consideration the impact of the season (spring, summer, autumn, winter), and sex of the animals. The studies have shown a high impact of the season of the year on those rabbits, but only in spring and summer. Moreover we observed that the sex has mean impact on the studied values of haematological parameters in those rabbits. According to our knowledge, this is the first paper on haematologic values in this widely used group of rabbits, so they may serve as reference values.

In Poland, rabbit is a highly valued animal, due to dietetic and flavour values of its meat, but above all, rabbits tend to be commonly used laboratory animals. The aim of the study was developing standards for counts of B-cells with CD19+ receptor, T-cells with CD5+ receptor, and their subpopulations, namely T-cells with CD4+, CD8+ and CD25+ receptor in the peripheral blood of mixed-breed Polish rabbits with addition of blood of meet breeds, including the assessment of the impact of four seasons of the year and animal sex on the values of the immunological parameters determined. The results showed that the counts of B- and T-cells and their subpopulations in peripheral blood remain within the following ranges: for CD19+ B-cells: 1.05 - 3.05%, for CD5+ T-cells: 34.00 - 43.07%, CD4+ T-cells: 23.52 - 33.23%, CD8+ T-cells: 12.55 - 17.30%, whereas for CD25+ T-cells: 0.72 - 2.81%. As it comes to the season of the year, it was observed that it principally affects the values of CD25+ T-cells, while in the case of rabbit sex, more changes were found in females.

Opis:
Mixed-breed rabbits in Poland are widely used for diagnostic and scientific research and as utility animals, therefore there is a need to know their immunological status, as well as their haematological status. In this study natural immunity factors were analyzed in Polish mixed-breed rabbits and Polish mixed-breed rabbits with addition of blood of meet-breed, considering the impact of sex and season of the year (spring, summer, autumn, winter) using measurement of non-specific cellular and humoral immunity parameters in peripheral blood. The study has revealed that there is a variety between the two commonly used mixed-breed types of rabbits, especially when sex and season is concerned, which is crucial for using these animals in experiments.
