Opis:
Many attempts have been made to develop a strategy for regulating forest use consistent with the multifunctional forest model. In this paper we present two proprietary methodologies of regulation of the allowable cutting size in a multifunctional forest in the 60−year time perspective. We assumed that all restrictions of nature protection and non−productive functions of the forest would still be in force. We based the first method on age class tables (TKW), which is faster but less exact in terms of spatial order of felling. The tree stand method (D−STAN) is based on stands spatial order and the cutting direction basis. In both cases, we based the temporal felling order on species rotation age. Comparing the results, we noticed that they present similar trends in the age structure of tree stands in younger age classes. The main discrepancies of the forecast concerns the share of forest stands in a complex structure: the TKW method gave approximately 12,4%, while the D−STAN one produced 5,1%. The latter approach shows that much smaller areas of stands are used for reconstruction. That marker is influenced by the spatial order of cutting used in the D−STAN model. In conclusion, we suggest to return to the big−area clear−cutting system on fresh coniferous habitats. Medium−area clear−cuttings should be brought back on the least fertile fresh mixed coniferous forests and possibly even fresh mixed deciduous forests.

Opis:
The paper presents declarative opinions of 239 tourists who visited the area of the Krynki Forest District in July−September 2013. The opinions were collected in direct interviews using of a questionnaire. The analysis distinguished two groups of respondents: 135 people (56,5%) who visited the forest district for the first time, and 104 respondents (43,5%) for whom it was the subsequent visit. We analysed the opinion of tourists on such problems as: (1) anthropogenic threats to the forest ecosystem, (2) factors constituting a threat to visitors to forest areas, and (3) forms of recreation and rest that can be implemented in forest areas. To examine the significance of mean differences between analysed groups of respondents that differ in experience and hypothetical readiness to declare the amount of WTP> 0, the Mann−Whitney test was used. Respondents considered forest fires and garbage left in the forest as the greatest threat to forest ecosystems, while among factors threatening people resting in forest areas, respondents pointed to the natural factors such as vipers, ticks and mosquitoes. Respondents considered that admissible forms of recreation and rest in forest areas are sport and cross−country races, horse riding and cycling, while ones that pose a threat to forest ecosystems, e.g. organization of mass events or bonfires and family events with barbecue, should be prohibited. No impact on differences in the opinions declared by the respondents, their tourist experience or readiness to declare the amount of WTP was disclosed.

Opis:
The aim of this study is to assess the economic efficiency of forest management based on the revenues and costs of selected activities and the financial result of the forest districts within the ‘Puszcza Białowieska’ Forest Promotional Complex (FPC), i.e. Białowieża, Browsk and Hajnówka forest districts. The assessment of the economic efficiency of the forest management in ‘Puszcza Białowieska’ FPC forest districts was analyzed in relation to the average values for comparative units (28 other forest districts) included in the Regional Directorate of State Forests (RDSF) in Białystok. In this study the profit and loss account and the basic reporting document on financial and economic activity (LPIR1) for the years 2011−2017 were used. Data were collected from the State Forests Information System. A detailed analysis of revenues and costs (from the sale of products, goods and materials), including administrative, basic, side, additional and social−living activities, as well as general administrative costs was made. The financial result of the FPC forest districts was also analyzed and then modified by increasing the net result by the value of the write−off for the forest fund and the maintenance costs of the superior units and reduced by the additional payment from the forestry fund. The amount of financial results of ‘Puszcza Białowieska’ FPC forest districts is mainly determined by revenues from the sale of woody raw material. Other types of activities do not have a significant impact on improving the financial result of these entities. The actual financial situation of ‘Puszcza Białowieska’ FPC forest districts reflects the modified net financial result, including for funds from the forest fund. Implementation of tasks in the field of nature protection and restrictions resulting from the acquisition of timber in ‘Puszcza Białowieska’ FPC forest districts significantly worsen their financial result. Implementation of additional tasks in the field of nature conservation causes a deterioration in the economic effi− ciency of forest management, which suggests extending the analyzes of other forest districts of the State Forests.

Opis:
The aim of this study is to assess the economic efficiency of the forest management with particular emphasis on economic and financial indicators of the forest districts (namely Białowieża, Browsk and Hajnówka) constituting the ‘Puszcza Białowieska’ Forest Promotional Complex (FPC). The work involved analysis of indicators reflecting the financial condition of the forest districts with reference to average values for comparison units i.e. 28 other entities from the Regional Directorate of the State Forests in Bialystok. The analysis consisted in the determination of typical values from comparative units in individual years (mean ±standard deviation). The balance sheet, profit and loss account and basic reporting document on financial and economic activities (LPIR1) for the years 2011−2017. Data were collected from the State Forests Information System. Financial liquidity, profitability and management efficiency were analyzed in detail. The net financial result of the forest districts was used for the analyzes, after an additional adjustment, consisting in increasing the net result by the value of the write−off for the forest fund and maintenance costs of the superior units and reduced by the additional payment from the forest fund. The analyzes were based on data collected from the State Forests Information System. On the basis of the research, it was found that the rules of financial management in the State Forests do not pose a risk of deterioration or loss of financial liquidity of the FPC forest districts. However, the inability to obtain the additional payment from a forest fund by individual of FPC forest districts would result in the loss of their ability to function independently. The management efficiency clearly affects the actual financial situation of the FPC forest districts. The deteriorating profitability of the FPC forest districts is caused by negative (loss) net financial results reflects the modified net financial result, including for funds from the forest fund. Restrictions on harvesting, resulting from the implementation of tasks in the field of nature conservation, worsen the economic efficiency of the FPC forest districts.

Opis:
The aim of the research was to determine the impact of selected habitat and age features on the qualitative properties of Scots pine (Pinus sylvestris L.). The research was carried out on forest stands from the Olesno, Wymiarki and Kalisz Pomorski forest districts (western Poland). The collected data provided information on technical and dimensional properties as well as quality classes for logs from Scots pine stands. The severity of the occurrence of seven basic wood defects, identified on the perimeter and length of the model log was identified and described. The collected data was used to determine the distribution of defect groups. For distributions of defect groups, normal distribution criteria were met. For the Scots pine assortments, the ANOVA showed that the hypothesis of the occurrence of an equal number of defects on the side of the logs in three separated classes of WA0, WB0 and WC0 of the quality of the raw material should be rejected. For the Tukey test, the results indicate that there is no reason to reject this hypothesis. The obtained p−value in this case is 0.09 for WB0 and WC0. There was no influence of the diameter of the logs and the habitat on the number of defects. Number of defect groups is correlated with the distance from the butt in Kalisz Pomorski and Wymiarki forest districts but not in Olesno. In that case the increase in the number of defect groups has its maximum in the zone of 6−8 m of the log length.

In this work, we presented the influence of the anodizing method and parameters, as well as the chemical composition of the used aluminium alloys on the properties and microstructure of the anodic layer produced on aluminium alloys, in particular on the size and morphology of the primary silicon precipitates and the homogeneity of the resulting oxide coating. Aluminium alloys AlSi8 and AlSi12, produced using the die-casting method and subsequently subjected to anodic oxidation were used as test material. The microstructure of the obtained surface layer was analyzed by taking into account the primary silicon precipitates. The results of the hardness and abrasive wear test also show the influence of anodizing and electrolyte parameters on the structure and properties of the tested aluminium alloys.

Opis:
Arbuscular mycorrhiza is one of the most common type of mycorrhiza in plant kingdom. Process of plant root colonization by arbuscular mycorrhizal fungi is consisted of four phases: presymbiotic phase, phase of contact and hyphae penetration to the roots, growth phase of hyphae inside the roots and phase of mycorrhizal intracellular structure development. The formation of symbiosis between fungi and host plant requires the exchange of molecular signals between these organisms. Plant signal molecules are described as strigolactones and cutin monomers whereas fungal signal molecules are lipo-chito-oligo-saccharides and short chito-oligosaccharides. During the contact with plant roots fungal hyphae form appresorium on the surface of epidermis. After appresorium creation, the pre-penetration apparatus (PPA) is formed in plant cell, which is a structure defining a route of the hyphae overgrowing across the plant cell. Afterwards the fungus penetrates the epidermal cell and the cell of root cortex, where hyphae leave the cell and enter into appoplast, growing and branching along the root axis.

Opis:
Zinc (Zn) is an important element for the proper plant growth and development. However, Zn is also a metal commonly used in the industry, which may cause its excessive accumulation in soil. High soil Zn content leads to its increased uptake by plants growing near industrialized areas. Arbuscular mycorrhizal fungi (AMF) live in symbiosis with the majority of plant species. These fungi have the ability to reduce Zn uptake by plants, when this element is present in an increased concentration in the plant root zone. An experiment was carried out to determine the effect of AMF on Zn uptake by lettuce plants grown in rockwool at increasing levels of Zn in the nutrient solution. This effect was investigated at two P levels in the nutrient solution, i.e. 40 mg P (optimal for lettuce) and 10 mg P dm-3. Mycorrhizal parameters, yield, content of dry matter, ascorbic acid, glucose, fructose and sucrose as well as the plant’s nutritional status in P, Cu, Mn, Mo, Fe and Zn were determined in the study. The effectiveness of mycorrhization of lettuce grown in rockwool was proven in the study. AMF reduced the Zn content in lettuce grown under excessive Zn concentrations in the root zone. Moreover, this decrease was greater in plants receiving the nutrient solution with a lower concentration of P. Additionally, mycorrhiza decreased the content of Cu, Fe, Mn and Mo in lettuce, despite an optimal (not increased) concentration of these micronutrients in the nutrient solution supplied to plants. Arbuscular mycorrhiza did not affect the plant yield, content of ascorbic acid, glucose, fructose, sucrose or the content of P in lettuce leaves.

Opis:
In this paper it has been described a computer system for the processing and analysis of two-dimensional digital images of evaluated pork half-carcasses. The AOPW (pol. Analiza Obrazu Półtusz Wieprzowych) image analysis system was created in C#, in Visual Studio 2015, using the AForge.NET library. The development of the application was preceded by a requirement analysis, according to the software engineering procedures. Documentation in the form of UML diagrams was developed in Microsoft Visio. The AOPW application is used to analyze and extract the characteristics of pork halfcarcasses contained in two-dimensional digital images acquired during the slaughtering process of pigs. The application may be a part of a new method for evaluating and classifying pig carcasses according to the applicable EUROP classification. The developed system was divided into two modules: the first for processing and filtering image, enabling e.g. edge and shape detection, sharpening and image binarization. The second allows for image analysis and acquisition of characteristics of pork half-carcasses - descriptors. The presented work was created within the research project of National Research and Development Center PBS3/B8/26/2015.
W pracy zaprezentowano autorski system informatyczny służący przetwarzaniu i analizie dwuwymiarowych obrazów cyfrowych, poddawanych ocenie półtusz wieprzowych. System o nazwie Analiza Obrazu Półtusz Wieprzowych (AOPW) został wytworzony w języku C#, w pakiecie Visual Studio 2015, z użyciem biblioteki AForge.NET. Opracowanie aplikacji zostało poprzedzone analizą wymagań, zgodnie z procedurami inżynierii oprogramowania. Powstała na tym etapie dokumentacja w postaci diagramów UML została przygotowana w programie Microsoft Visio. Aplikacja AOPW służy do analizy i ekstrakcji cech charakterystycznych półtusz wieprzowych, zawartych na dwuwymiarowych obrazach cyfrowych pozyskanych w trakcie procesu uboju trzody chlewnej. Aplikacja może stanowić element nowej metody oceny i klasyfikacji półtusz wieprzowych według obowiązującej klasyfikacji EUROP. Opracowany system został podzielony na dwa moduły: pierwszy przetwarzający i filtrujący obraz, umożliwiający m.in. wykrywanie krawędzi i kształtów, wyostrzanie oraz binaryzację obrazu; drugi pozwalający na analizę obrazu i pozyskanie cech charakterystycznych – deskryptorów. Przedstawiona praca powstała w ramach projektu badawczego Narodowego Centrum Badań i Rozwoju PBS3/B8/26/2015.

Opis:
Introducing integrated system ZSIKRP have important implications for increased passenger comfort and improve the technical level and reduce the maintenance costs of rail vehicles. Currently the majority of manufacturers of rolling stock is focused on meeting the TSI requirements in the context of the interoperability of rolling stock within the ERTMS/ETCS and in these works there is no place for activities aimed at introducing systems supporting the work of the driver and increase the safety of passengers. The adopted within the framework of ERTMS/ETCS work focused on ensuring the safety of structural (as defined in the standard EN 50129), while the project ZSIKRP focused on the safety of travellers and safety resulting from the technical conditions in rail transport as well as in the context of protection against attacks of aggression. A special module was devoted to the role of optimizing the fuel consumption of the vehicle SA 132-006 (type SZT) and energy in EN 57-1756 (type EZT).
Wprowadzenie zintegrowanego systemu ZSIKRP ma istotne znaczenie dla zwiększenia komfortu pasażerów i zmniejszenia kosztów eksploatacji i utrzymania pojazdów szynowych. Obecnie większość producentów taboru koncentruje się na spełnienie wymagań TSI w kontekście interoperacyjność taboru w ramach ERTMS / ETCS. W tych obszarach nie ma celowości dla działań mających na celu wprowadze-nie systemów wspomagających pracę maszynistów i poprawiających bezpieczeństwo pasażerów. Przyjęta w ramach ERTMS /ECTS prace skoncentrowane są na zapewnieniu bezpieczeństwa elementów struktury systemu (jak zdefiniowano w normie EN 50129), natomiast projekt ZSIKRP zorientowany jest na bezpieczeństwo podróżnych i bezpieczeństwo wynikających z warunków technicznych w transporcie kolejowym, a także w kontekście ochrony przed zagrożeniami. Dodatkowo opracowano specjalny moduł dedykowany do optymalizacji zużycia paliwa przez pojazd SA 132-006 (typ SZT) i energii w EN 57-1756 (typu EZT).

Opis:
An huge interest is observed in last years in metal matrix composite, mostly light metal based, which have found their applications in many industry branches, among others in the aircraft industry, automotive-, and armaments ones, as well as in electrical engineering and electronics, where one of the most important issue is related to the corrosion resistance, especially on the surface layer of the used aluminium alloys. This elaboration presents the influence of ceramic phase on the corrosion resistance, quality of the surface layer its thickness and structure of an anodic layer formed on aluminium alloys. As test materials it was applied the aluminium alloys Al-Si-Cu and Al-Cu-Mg, for which heat treatment processes and corrosion tests were carried out. It was presented herein grindability test results and metallographic examination, as well. Hardness of the treated alloys with those ones subjected to corrosion process were compared.

Opis:
This paper presents the influence of casting method and anodic treatment parameters on thickness and structure of an anodic layer formed on aluminium alloys. As test materials was used the aluminium alloy AlSi9Cu3, which was adopted to the casting process and anodic treatment. In this paper are presented the wear test results and metallographic examination, aswell as hardness of non-anodised and anodised alloys subjected to anodising process.The investigations were performed using light and electron microscopy (AFM) for the microstructure determination. The morphology and size of the layer was also possible to determine. The anodising conditions for surface hardening and itsinfluence on properties was analysed. The structure of the surface laser tray changes in a way, that there is a different thicknessof the produced layer. The aluminium samples were examined in terms of metallography using the optical microscope withdifferent image techniques as well as light microscope. Improving the anodization technology with appliance of differentanodising conditions. Some other investigation should be performed in the future, but the knowledge found in this researchconcerning the proper process parameters for each type of alloy shows an interesting investigation direction. The combinationof metallographic investigation for cast aluminium alloys - including electron microscope investigation - and anodisingparameters makes the investigation very attractive for automobile industry, aviation industry, and others, where aluminium alloys plays an important role.
