Opis:
For many centuries, management of the Białowieża Forest has not focused on timber production. Therefore, despite hunting, grazing by domestic animals and sporadic cutting of valuable trees the forest has retained its natural character. After World War I, a small part of the Białowieża Forest was protected as a reserve that later became a national park, while the remainder was managed for timber. After World War II, the protection status of the Polish part of the Białowieża Forest was maintained with the national park at the center surrounded by managed stands. During the last few decades, the national park was enlarged and new reserves were established. However, the majority of the Białowieża Forest is still managed for timber. The forest management has been sustainable for decades and in the last few years logging has even been strongly reduced, to a level comparable with some national parks. In recent years the Białowieża Forest, like many areas in Central Europe, has been plagued by a high spruce mortality caused by bark beetles. In managed forests, cutting the infested spruces and removing them from the forest is a standard practice aimed at reducing the growth rate of the bark beetle population. This, however, raises the question of whether we expect the Białowieża Forest to remain a managed forest, in which case the fight against bark beetles would be justified, or whether we want it to be converted into a large national park? In the latter case, cutting trees to fight bark beetles would be inconsistent with the aim of conservation. Recent discussions concerning the Białowieża Forest have been dominated by two different ideologies for nature protection. The first approach aims at protecting nature to make it sustainable, beautiful and healthy. In the second approach, protecting nature is achieved by removing any direct human influence, even if the resulting natural environment does not meet our expectations.

Opis:
Natural weathering processes can make coal surface more hydrophilic due to the increase of content of hydrophilic functional groups (C-O, C=O, and COOH) and the decrease of content of hydrophobic functional groups (C-C and C-H) on coal surface, and hence the flotation recovery of fine coal is reduced. In this paper, a series of flotation tests were conducted in order to investigate the changes in the flotation kinetic of bituminous coal before and after natural weathering processes. Additionally, XPS was used to indicate the changes in surface properties of bituminous coal. In the investigations the flotation kinetic was changing. The classical first-order rate constant (k) of bituminous coal flotation was reduced after the natural weathering processes. A relationship between the classical first-order rate constant (k) and the hydrophilicity ability (HA) was given.

Opis:
Celem niniejszej pracy jest analiza ochrony przyrodniczych procesów usług środowiska (świadczeń ekosystemów, ang. ecosystem services) jako elementu kapitału naturalnego (ang. natural capital) w perspektywie tworzącej się ekonomii zrównoważonego rozwoju (ang. economics of sustainable development). Jego realizacja wymaga analizy procesów kształtowania się i założeń ekonomii zrównoważonego rozwoju, istoty kapitału naturalnego, a także teoretycznych filarów ochrony przyrodniczych procesów usług środowiska. Przyrodnicze procesy usług środowiska wymagają pogłębionych i poszerzonych badań jako element kapitału naturalnego. Dotychczasowe teorie w zakresie ekonomiczno-ekologicznym w zdecydowanej większości były budowane w oparciu o elementy zasobów i walorów środowiska przyrodniczego. Ponadto intensyfikacja międzynarodowych i krajowych badań nad kategorią usług środowiska jednoznacznie uwidacznia konieczność zwrócenia uwagi na ich ekologiczne podstawy, które stanowią przyrodnicze procesy w ekosystemach.
The purpose of this paper is to analyze the protection of the natural processes of ecosystem services as part of the natural capital in the perspective of the emerging economics of sustainable development. Its implementation requires the analysis of development processes and the assumptions of economics of sustainable development, the essence of natural capital, as well as the theoretical pillars of the protection of the natural processes of ecosystem services. Natural processes of ecosystem services require in-depth research and expanded as part of the natural capital. Previous theories in the field of economic and ecological in the vast majority were built on the basis of elements of the resources and values of the natural environment. Moreover, the intensification of international and national research on the category of ecosystem services clearly emphasizes the need to pay attention to their ecological base, which are natural processes in ecosystems.

Opis:
Despite the fact that only parts of the Białowieża Forest are protected as a national park and nature reserves, the forest is nevertheless as a whole considered a U NESCO Natural Heritage Site, Biosphere Reserve and an integrated Natura 2000 site. In the presently ongoing debate on the conservation priorities regarding the natural value of this forest and the current bark beetle outbreak, two distinct approaches can be recognized: (1) management assumed to involve considerable interference with the forest ecosystems; (2) maintenance of ecological processes and spontaneous restoration of the forest communities. The Białowieża Forest – especially its strictly protected parts – is a “bastion” where species characteristic of ancient forests (including so-called primeval forest relicts) have survived until today. This has been achieved by maintaining the forest’s complexity in areas with considerably reduced human influence, but most of all by maintaining a full spectrum of forest communities, naturally developing forests diverse in age, species composition and spatial structure including stand dieback and breakdown. The following factors need to be taken into account in the protection of the Natural Heritage Site: (1) the internationally recognized value of the Białowieża Forest including its biodiversity, the level of preservation of forest communities and the ongoing natural processes; (2) existing documents and policies concerning nature conservation; (3) research findings from the Białowieża Forest and other natural forest complexes. The key priority is to limit any activities in this forest to an indispensable minimum, mostly concerning security close to roads and tourist tracks as well as collection of fire wood by locals. Without this strict protection, successive and slow anthropogenic transformation will result in the Białowieża Forest sharing the same fate as other forest complexes of the temperate climate zone in Europe or America and lose its globally appreciated value.

Opis:
Carvone is a key component of essential oils from the Anethum graveolens L. (dill) and Mentha spicata L. (mint) plants. It was obtained in pure form by preparative isolation from the Mentha spicata essential oils. It has been established that essential oils contain carvone in various optically active forms. The essential oil of dill contains d-(R)-carvone (right-rotating isomer form) with a specific rotation of the plane of polarization [α]D + 62.5 + 0.05; mint essential oil from Mentha spicata contains l-(S)-carvone (left-rotating isomer form) with a specific rotation of the plane of polarization [α]D – 63.2 + 0.05. An organoleptic analysis reliably determined the aromatic characteristics of carvone: (S)-carvone of dill essential oil has a spicy aroma of fresh dill, in turn (R)-carvone of mint essential oil from Mentha spicata – has the aroma of cumin with menthol tones. The research of the method of accelerated oxidation proved that the introduction of antioxidants in the form of optical isomers into sunflower oil leads to an increase in the concentration of fat-containing products by 2.4–3.0 times by the values of peroxide number and 1.5–1.7 times by the values of acid number, in comparison with control. Comparing the effect of carvone optical isomers among themselves by the oxidation dynamics of fat-containing products, it was found that in general their protection effect is similar. However, the leftward carvone shows a higher effect on the resistance of sunflower oil as compared with the rightward carvone. Except for the protection from oxidation, the optical isomers of carvone can have a physiological effect on a human body. Thus, the optical isomers of carvone can add certain aromas to foodstuffs, and when functional fat-containing products are created, it is possible to use both optical forms of carvone, depending on the orientation of a new functional product.

Opis:
W trakcie przepompowywania gazu z głównego rurociągu do magazynu gazu i odwrotnie pojawiają się turbulencje, które często powodują występowanie potężnych drgań przewodu. Powoduje to osłabienie połączeń gwintowanych; dolne rury często oddzielają się i wpadają do otworu, negatywnie wpływając na prawidłowy przebieg produkcji i powodując obniżenie wydajności. Nieprzytwierdzony dolny odcinek kolumny odgrywa decydującą rolę w powstawaniu drgań. Przymocowanie dolnej części kolumny za pomocą opisanych urządzeń znacznie zmniejsza amplitudę drgań i poprawia stan połączeń gwintowanych
While pumping gas from the main pipeline into the gas storage and vice versa, turbulent processes appear in the well that quite often results in considerable vibrations of the lover part of the column of the tubing string. Because of this, the column screw thread halving is weakened; lower pipes sometimes unscrew and fall into the well. It substantially violates the normal operating mode of the gas storage and negatively affects its productivity. If the lower end of the column is not fastened then it takes the dominant role in the vibration processes. Fixing the lower part of the column by means of spacing devices substantially enables decreasing the amplitude of the tubing string and improving the conditions of the screw thread halving

Opis:
Natural environment of high mountains is undergoing rapid changes. One of its elements is the relief. What needs to be particularly emphasized here is its contemporary morphogenesis. The aim of the study is an attempt to define the predisposition of natural environment of the chosen region (NW) of the Pamirs towards the development of contemporary morphogenetic processes. In order to carry it out, quality classes method was implemented. Quality classes method was carried out on two kinds of basic fields of assessment: geometric and natural (geomorphologic). It was preceded by a selection of 14 characteristics of the study area, elements or components of the natural environment, which were analysed from the perspective of their influence on initiating, change of intensity or vanishing of the contemporary land formation processes. Maps of predisposition of natural environment of north-western part of the Pamirs towards the development of modern morphogenetic processes for the two kinds of fields constitute the final result of the study. Gained results enable to state that the significant part of the study area is characterized by big predispositions towards the development of contemporary morphogenetic processes. However, on the basis of research on location it was find out that in a few places there is a more intensive forming of the surface than it results from the gained results. Areas of average and small predispositions almost precisely coincide with the range of big Pamirs glaciers. Moreover, it can be said that an extremely important issue for the high mountain region characterized by a big spatial changeability of all analyzed elements of natural environment is the size of the basic field of assessment.

Opis:
Liquefied natural gas (LNG) has an increasingly important role in the global natural gas market. Global demand for natural gas will grow over the coming years. LNG is transported by ships to unloading points on the storage terminals. During the LNG unloading and storage processes some part of LNG evaporates into gas phase and causes changes in the composition of stored LNG. The main component of LNG is methane, the remaining components are primarily ethane, propane, butane and nitrogen. Depending on the participation of these components the basic thermodynamic parameters of LNG can significantly change. LNG is also product sensitive to changes of temperature. In order to better prediction of changes of individual paramete rs of stored LNG caused by changes of temperature and LNG composition vapor-liquid equilibrium (VLE) calculations are performed for cryogenic conditions using equations of state.

Opis:
The paper presents the results of studies of geomorphological processes in the surroundings of tourist paths with an effect on vegetation and soil conditions in the subalpine and alpine zones of the Tatra Mts. Hiking paths at the local level represent a significant factor for increasing efficiency of sheet wash and concentrated runoff and subsequent intensive deep erosion. They can interrupt continuous surface runoff and operate as the local base of erosion base for a part of the slope over them, with gravitational effect of surface runoff from rainfall and melting snow water, which increases the effect of slope denudation. The base of erosion of the paths increases the potential of gravitational failures and decreases the soil-debris cover stability. In these conditions, the development of slope movements accelerated evidently. Morphologically, hiking path can influence the accumulation of snow layers and creates the conditions for persistent snowfields. Blocking effect of the paths is also reflected in a slowdown and the subsequent accumulation of snow mass by snow creep, snow sliding and snow mass gliding. Hiking paths may be a part of areas with development of aeolian-deflational processes and associated destructions of the soil-debris cover.

The article concentrates on the development of theoretical and methodological foundations of statistical research in the field of national environmental and economic accounting, which forms the basis for the development of indicators of climate change under martial law and shapes the adaptation to these changes. Given Russia's military aggression against Ukraine, the national statistical system is faced with an urgent task of ensuring the continuity of the production of complete and high quality statistical information. The issue of forming a methodology for the production of statistical information in the field of ecology, i.e. climate change statistics, remains unresolved. Outlining ways to address this issue is an important condition for the improvement of modern state statistics of Ukraine and the development of statistical theory and practice, as this largely determines the quality of the information-related support for environmental management at all levels. The statistical estimation of the dynamics and structure of greenhouse gas emissions on the basis of the economic activity of enterprises was performed. It was pointed out that among the various related branch methods of obtaining information, the system of environmental and economic accounting is the most relevant and source of high quality data. One of the aspects of solving the complex problem of forming methodological bases for collecting statistical environmental information is the creation of a national system of indicators of climate change and preparing statistical informational products using administrative data sources. The paper studies issues of producing ecological information relating to Ukraine according to statistical data. Moreover, the main problems which arise during the construction of national environmental accounts were characterised. Finally, the paper identified the key factors which influence to the largest extent the quality of statistical data and calculations, and which are necessary for the transformation and development of the statistical estimation of climate change under Russian military aggression.
