Opis:
Motivation: The Bank Guarantee Fund (BFG) operates by following two formulas, one of which is the implementation of the disbursement of guaranteed amounts. The BFG has been changing the limits of the guaranteed amounts, streamlining and improving the way in which the disbursements are made, as well as conducting information activities. The interest in analysing these activities is the original motive that prompted the present topic. Aim: The aim of the article is to evaluate the effectiveness of the BFG's deposit guarantee activity by: showing the history of the limit of guaranteed amounts, reviewing selected items of the BFG's balance sheet and the collateral ratio of the deposit guarantee scheme. The 28 years of the BFG's existence have forced the Fund to make progress with computerisation, which is analysed on the basis of the implementation of payouts of two failed banks in Poland. The purpose of the survey is to verify the indirect information activity of the BFG. Materials and methods: The research tasks were made possible through the use of descriptive analysis, financial analysis, a case study and a survey. The information contained in academic articles, annual reports of the BFG and in the BFG acts was used. Results: High stability and security of the banking sector is crucial. The BFG's main investment is in securities of the State Treasury and the NBP, which guarantees the deposits of bank customers. The small institutions that are covered by the BFG regime show the highest level of safety, due to the limited risk of contagion in case of their failure. However, large banks have to look after their own interests, as most companies have accounts in these banks. The survey showed low public awareness of deposit guarantees. The BFG should improve its information activities, e.g. with TV and radio advertisements.

Opis:
The deposit guarantee system in Poland was devised at the time of the economic transformation. Its creation resulted from a difficult situation in the banking sector, and so it was meant to be an antidote to clients’ problems associated with the insolvency of collapsing banks and with adjusting to European community law. The aim of this work is to present the Bank Guarantee Fund-an institution that is part of the financial safety net, whose main task is to protect the interest of depositors and to ensure the banking system’s stability. The paper looks at some aspects of the growing interest in bank deposit insurance schemes and lively discussions on the subject during a crisis in banking markets. In response to the crisis that started in the subprime lending market in the USA and spread to other segments of the financial markets as well as to other countries, the ECOFIN made a decision to increase the existing guarantee limits for individual persons and to speed up the payout of guaranteed funds. The above changes were aimed at strengthening the security of clients and increasing confidence in the banking sector.

Opis:
Theoretical background: The global financial crisis (GFC) has shown the importance of the funding model for the bank’s stability. In this context, deposits were of particular importance as they proved to be a stable source of funding during market turmoil. As a result, many banks have changed the funding model, paying greater attention to financing obtained on the deposits market. Purpose of the article: In this paper, we analyze the impact of funding models on the EU banks’ risk after GFC, i.e. in 2011–2018. We put particular emphasis on the funding structure measured by the deposits to total assets ratio and changes that take place according to the type of institution (i.e. listing status, specialization, and funding model). Research methods: In our research, we use panel data models together with a set of tests that allow us to deduce about properties of proposed models and allow us to analyze the significance of the impact of the bank-specific, macroeconomic, and dummy variables on the bank’s risk. We apply “within”, “fixed time effects” estimator from plm R package. Main findings: We confirm the stabilizing function of deposits, but also the non-linear nature of the impact of the funding structure on the bank’s stability, depending on the bank’s specialization. This means that the stabilizing role of deposits for the bank’s stability is just as important in the post-crisis period as it was during the outbreak of GFC in 2008, although the excessive growth of deposits in some types of banks may, however, lead to an increase in the risk level.

Opis:
This paper presents the results of diagnostic examinations conducted on the water pipe made of grey cast iron that were operated in conditions for 260 thousand hours. The tube was exposed in a soil. The phase composition of the deposit layers formed on both sides of the tube walls (outside and inside) was examined using optical and confocal microscopy and X-ray diffraction. The obtained XRD test results showed that mainly -FeOOH) and γ-FeOOH is formed on the inside of the pipe wall. In turn, on the outside, in addition to the above-mentioned compounds, also SiO2 is formed. The results of these examinations have shown a higher degradation of pipe on the outer side. The arithmetic mean deviation of the profile from the mean line was 6.23 µm and 8.07 µm for the inner and outer side of the pipe wall, respectively. The work demonstrates the usefulness of material science, especially X-ray structure, topography and surface studies, in characterizing the degradation processes of layers formed on gray cast iron exploited in the water supply industry.

Opis:
Cost-efficient, enabling technologies for keeping and increasing the reservoir recovery rate of oil-formations with high water cut of produced fluids and exhausted resource are really essential. One of the easiest but short-term ways to increase oil production and incomes at development of oil deposits is cost of development and capital cost reduction. Therefore, optimal choice and proper feasibility study on the facilities for multilayer oil fields development, especially at the late stage of reservoir working, is a crucial issue for now-day oil industry. Currently, the main oil pools do not reach the design point of coefficient of oil recovery. The basic feature of the late stage of reservoir working is the progressing man-made impact on productive reservoir because of water injection increasing for maintaining reservoir pressure. Hence cost-efficient, enabling technologies for keeping and increasing the reservoir recovery rate of oil-formations with high water cut of produced fluids and exhausted resource are really essential. To address the above concerns the dual completion petroleum production engineering was proposed. The intensity of dual completion of formation with of different permeability is determined by rational choice of each of them. The neglect of this principle results a disproportionately rate of highly permeable formations development for the time. In effect the permeability of the formations or their flow rate is decreasing. The problem is aggravated by lack of awareness of mechanics of layers' mutual interference in producers and injectors. Dual completion experience in Russian has shown, that success and efficiency of the technology in many respects depend on engineering support. One of the sufficient criteria for the choice of operational objects should be maximal involvement of oil-saturated layers by oil displacement from seams over the economic life of well producing oil. If it is about getting high rate of oil recovery for irregular formations there is no alternative to dual completion and production. The recommended dual completion petroleum production technology enables development several formations by single well at the time. The dual completion petroleum production technology has been more important than ever because it is right not only for formations but for thin layers with undeveloped remaining reserves.

Subject and purpose of work: The literature on financial development and economic growth is expansive. The proportion of individuals and firms that use or have access to financial services can be referred to as the financially included. Considerable evidence shows that the poor benefit more from access to basic financial services such as payments, savings accounts and insurance. Thus, this study analysed the impact of financial inclusion on financial development in Nigeria between 1982 and 2019. Materials and methods: Multiple regression analysis was employed in the study in order to properly estimate the models and get robust results. Results: The findings reveal that financial inclusion has a minor impact on financial development. Investment was also shown to improve financial development. Conclusions: The study recommended that policies should be directed towards creating a more inclusive financial system in order to improve the current level of financial inclusion, so as to achieve better financial development in Nigeria.

Opis:
The PGI research of lignite was primarily focused in the area of eastern Poland. An extensive research of the lignite deposit geology mmediately after the end of World War II led to numerous discoveries of large lignite deposits, including some of the biggest in Europe (Legnica, Bełchatów, Poznań Tectonic Trough). The data collected during exploration and prospection of lignite deposits made possible to elaborate stratigraphy (litho- and palynostratigraphy) of Paleogene/Neogene lignite-bearing association on the Polish Lowlands and prepare its detail correlation with the stratigraphic schemes of East Germany. Sedimentological studies of lignite-bearing association led to the definition of basic types of lignite-bearing facies, related to sedimentary conditions in different zones of alluvial sedimentary basins. They also allowed the establishment of relationships between lignite-bearing sedimentation and tectonic evolution of the lignite basins in tectonic depressions and cups of salt domes. Recently, the impact of climate change on the development of brown coal sediments has been subject to study and the critical thermal conditions for the most intense anthracogenesis in the Polish Lowlands, which took place in Miocene, were defined.

Opis:
Wydobywany z dołu kopalń urobek węglowy stanowi mieszaninę ziaren węglowo-odpadowych, która nie posiada praktycznie na rynku zbytu żadnej wartości użytkowej. W celu uzyskania węglowego produktu handlowego urobek poddawany jest procesom wzbogacania w zakładach przeróbki mechanicznej węgla. W warunkach przemysłowych proces ten opiera się na wykorzystaniu grawitacyjnych metod wzbogacania w ośrodku wodnym bądź w cieczy ciężkiej magnetytowej. Przyjęte od lat i modyfikowane metody produkcji węgla handlowego powodują powstawanie znacznej ilości ubocznej produkcji w postaci murów węglowych. W Centrum Gospodarki Odpadami i Zarządzania Środowiskowego Oddziału Zamiejscowego Instytutu Mechanizacji Budownictwa i Górnictwa Skalnego wspólnie z Katedrą Przeróbki Kopalin i Utylizacji Odpadów Politechniki Śląskiej realizowany jest projekt badawczo-rozwojowy pt. "Identyfikacja depozytów mułów węglowych w bilansie paliwowym kraju oraz strategia rozwoju technologicznego w zakresie ich wykorzystania". Głównym celem realizowanego projektu jest określenie możliwości włączenia wprost lub poprzez zastosowanie odpowiednich procesów wzbogacania do krajowego bilansu paliwowego istniej?cych depozytów mułów węglowych. Realizacja projektu przyczyni się również do wypełnienia zapisów Dyrektywy 2006/21/WE Parlamentu Europejskiego i Rady w sprawie gospodarowania odpadami pochodzącymi z przemysłu wydobywczego oraz ustawy z dnia 10 lipca 2008 r. o odpadach wydobywczych (Dz.U. z 2008 r., Nr 138, poz. 865 z późń. zm.) transponującej zapisy wymienionej dyrektywy do ustawodawstwa polskiego, m.in. w zakresie hierarchizacji postępowania z odpadami wydobywczymi zobowiązującej wytwórców do ograniczenia ilości składowanych w środowisku odpadów wydobywczych oraz likwidacji istniejących obiektów na których były one deponowane W ramach wymienionego projektu w pierwszej kolejności przeprowadzono inwentaryzację istniejących obiektów wraz z identyfikacją ilościową i jakościową. Następnie opracowano model matematyczny, pozwalaj?cy na obliczenie potencja?u energetycznego każdego badanego obiektu, co umożliwi w przyszłości wskazanie potencjalnych odbiorców wraz z określeniem ilości możliwych dostaw. Opierając się na dokonanej ocenie oddziaływania zinwentaryzowanych depozytów mułów węglowych na różne komponenty środowiska oraz opracowanym punktowym systemie oceny, ustalona została lista rankingowa obiektów stanowiących potencjalnie największe zagrożenie dla środowiska uwzględniająca: stan aktualny, fazę ewentualnej eksploatacji oraz stan po jej zakończeniu. Określone zosta?y także kierunki, zakres oraz wytyczne projektowe przyszłej rewitalizacji terenów poeksploatacyjnych. Dla zinwentaryzowanych oraz zidentyfikowanych jakościowo i ilościowo depozytów mułów węglowych opracowano technologie ich wzbogacania na pełnowartościowe paliwo dla energetyki zawodowej, uwzględniające zróżnicowaną strukturę fizyczną i parametry chemiczne. Przedstawiono również kierunki potencjalnego gospodarczego wykorzystania odpadów powstających w wyniku wzbogacania depozytów mułów węglowych jako materiału mineralnego przy produkcji kruszyw sztucznych z osadów ściekowych i szkła odpadowego, jako wypełniacza przy produkcji mieszanek związanych hydraulicznie oraz jako dodatku do wyrobów ceramicznych. Końcowy etap projektu stanowić będą propozycje rozwiązań technicznych, organizacyjnych i prawnych - wraz ze strategią rozwoju technologicznego - zmierzających do wykorzystania zinwentaryzowanych w sposób ilościowy i jakościowy depozytów mułów węglowych w krajowym przemyśle energetycznym. Realizacja projektu dostarczając know-how przyczyni się do powstawania i rozwoju przedsiębiorstw innowacyjnych, szczególnie w sektorze małych i średnich przedsiębiorstw zainteresowanych świadczeniem usług dla sektora wydobywczego i energetycznego. Będzie to wynikiem przeznaczenia produktu uzyskiwanego w procesie wzbogacania, jak i pozostałości po procesie wzbogacania dla szerokiego grona odbiorców. Umożliwi również powstanie firm
Mined from the bottom of coal mine spoil is a mixture of particles of carbon - waste that does not have any value on the market. In order to obtain commercial coal product, mining output is subjected to enrichment processes in coal preparation plants. Under industrial conditions, this process is based on the use of gravity methods of enrichment in a water environment or in a magnetite heavy liquid. Gradually developed over the years, methods of commercial coal production generated a considerable amount of secondary production in the form of coal sludge. The Centre of Waste and Environmental Management, a branch of the Institute of Mechanized Construction and Rock Mining, together with the Department of Mineral and Waste Disposal of the Silesian University of Technology, undertook the research and development project titled “Identification of the energy potential of coal sludge deposits in the national fuel balance and technological development strategy for their use.” The main objective of the project is to identify opportunities for inclusion, either directly or through appropriate processes of enrichment, in the national fuel balance of existing deposits of coal sludge. The project will also contribute to the fulfillment of the provisions of Directive 2006/21/EC of the European Parliament and the Council on the management of waste from extractive industries, and the Act of 10 July 2008 on mining waste (Journal of Laws of 2008, No. 138, item. 865) which transposes the provisions of the above Directive into Polish legislation in the hierarchy of management of extractive waste, requiring manufacturers to limit the amount of waste deposited in the mining environment and to decommission existing plants on which they were deposited. As part of the above mentioned project, an inventory of existing facilities was performed, along with conducting quantitative and qualitative identification. Then, a mathematical model was created to calculate the energy potential of each test object which will, in the future, identify potential customers and the identity number of possible deliveries. Based on this assessment of the impact of coal sludge deposits inventoried, including various components of the environment and the developed scoring system, a ranked list was fixed of objects which potentially comprise the greatest threat to the environment, taking into account the following: the current state, the phase of any operation, and the state after its completion. Direction, scope, and design guidelines for future revitalization of voids were defined. For inventoried and qualitatively and quantitatively identified deposits of coal sludge, technologies were developed for their enrichment into fuel for power plants, taking into account the diverse physical structure and chemical properties of the deposits. The work also presents directions for the potential use of waste resulting from the enrichment of coal sludge deposits as the mineral material in the production of artificial aggregates of sewage sludge and waste glass as a filler in the production of hydraulically bound mixtures, and (in addition to ceramics. The final stage of the project will be proposals for technical, organizational, and legal solutions – with a strategy of technological development - designed to use the inventoried quantity and quality of coal sludge deposits in the domestic energy industry. Implementation of the project by providing “know-how” will contribute to the creation and development of innovative enterprises, especially small and medium sized companies interested in providing services for the mining and energy sector. This will be the result of the use of the product obtained in the process of enrichment and the enrichment process residues by a wide variety of recipients. It will also enable the creation of “spin-off” companies operating on the basis of the project’s developments of innovative technologies using coal sludge deposits and residues from the enrichment process. These companies may perform services for the mining and energy sector, contributing to the spread of new technologies in the economy
