The deepening and exploration of the loess-palaeosol section at the foot of the Kopasz Hill at Bodrogkeresztúr have been carried out to expand the existing knowledge of the Carpathian foothill palaeoenvironmental factors and their impact. The study deals with particle size analysis, organic matter and carbonate content. For the presentation of age-depth models, the OSL dates of Bodrogkeresztúr (BKT) and the 14C dates of Bodrogkeresztúr, brickyard 1 were used-, and the diagrams of the Accumulation Rates (AR) derived from them. These were compared with Mass Accumulation Rate (MAR) calculations based on OSL and 14C data from BKT and 14C data from Bodrogkeresztúr, brickyard 1. It became evident that there is a significant difference between the two sections, which may be due to the upland position, the overlap, or the wind tunnel effect. Sedimentological studies revealed coarser grain composition, however, the nearly complete absence of coarser sand fraction is also noticeable in the case of BKT. Also, the entire section is characterized by increased carbonate content due to post-sedimentation processes, recarbonization and leaching. The AR and MAR results show the difference between the suitability of different chronometric methods, indicating that the top of both sections may have been redeposited or eroded.

In 2018, Poland was granted the right to explore for ores in the area of the Mid-Atlantic Ridge area of 10 000 km2, which is the initial stage of the Program of Geological Exploration of Oceans (PRoGeO) accepted by the Government of Poland in July 2017. On the part of decision-makers, expectations are huge in ensuring safe deliveries of a number of metals (Cu, Au, Ag, Pt, REE, Ni, Co, Zn and Mo). The authors carried out a detailed analysis of the published results of research on similar objects in the exclusive economic zones of Japan and Papua New Guinea. Comparative analysis, covering geological-economic, organizational, financial, geo-environmental aspects reveals that in the Polish zone of the MAR one can expect to find rich, but relatively small deposits of Cu, Zn, Ag, and Au, which meet the needs of a small part of domestic demand for these metals in less than 2 years. The geological and economic analysis shows that there is no risk of a collapse of the supply market for these metals. On the other hand, the risk of organizational and financial failure of the oceanic research project was defined as very large. The authors do not deny the need to conduct basic oceanic research. On the contrary, such research should be carried out even if the economic goal is very distant in time and vaguely outlined. However, the method ofpreparing and evaluating the program of such research should not differf rom the standards adoptedfor serious research grants, so it should have an original character, be prepared by leading research centers in a given field and be thoroughly evaluated by independent experts. Then a wide discussion will be possible in the scientific community regarding the purposefulness, scope and costs of the work.

This article introduces a groundwater vulnerability assessment model that utilises the fuzzy analytic hierarchy process (FAHP) in the Wadi AlHasa catchment, Jordan. The assessment takes into account both geomorphological and hydrogeological variables, employing a comprehensive methodology that integrates various parameters. To evaluate the catchment, the study employs remote sensing and Geographic Information System (GIS) techniques. The analysis of the digital elevation model enables the creation of a map illustrating the diverse geomorphology of the catchment. This geomorphology significantly influences drainage density, direction, and the spatial distribution and intensity of flash flood events. Moreover, the study develops and maps a fuzzy FAHP DRASTIC vulnerability index, which proves to be a valuable tool for assessing the susceptibility of groundwater resources to contamination. The unique feature of the index is its ability to incorporate uncertain or subjective data, providing a means to evaluate the significance of various influencing factors. This information serves as critical support for decision-making and management efforts geared towards safeguarding and enhancing groundwater resources. Within the study area, the DRASTIC vulnerability index values span from 0.08325 to 0.28409, with 18% of the site exhibiting a high vulnerability rate. Additionally, the article implements a managed aquifer recharge model (MAR), with 31% of the area falling into MAR classes. Among these, 22.1% are classified as a high MAR class, while 0.7% belong to a very high MAR class. These findings underscore the feasibility of MAR projects in regions with limited water resources.

W artykule autorzy wskazują na potencjalne ryzyka, jakie stwarzają nowe regulacje rynku finansowego dla koncernów elektroenergetycznych. Przedstawiają również wzajemne zależności przywołanych aktów prawnych. Pozwalają one na weryfikację hipotezy, iż proponowa-ne kompleksowe uregulowanie funkcjonowania rynków towarowych będzie z jednej strony istotnym wyzwaniem formalno-organizacyjnym dla uczestników obrotu, a z drugiej – katalizatorem nowych obszarów ryzyka dla tych przedsiębiorstw. Ponadto, ograniczenie – w wyniku wejścia w życie nowego systemu regulacyjnego – możliwości hedgingu może zwiększyć ryzyko rynkowe, a w konsekwencji wykreować ryzyko systemowe w innych obszarach rynku finansowego niż uznane pierwotnie za narażone na wzrost ryzyka tego typu i z tego powodu objęte regulacjami w pierwszej kolejności. Ograniczenie się zaś tylko do transakcji krótkoterminowych poza rynkiem finansowym może odbić się negatywnie na wynikach finansowych koncernów elektroenergetycznych oraz ich ratingach finansowych.

The paper attempts to identify potential risks posed by new regulations of the financial market for electric power companies. The authors also elaborate on the interdependence of the legal acts relating to the financial markets, which allow the verification of the hypothesis that the proposed comprehensive regulation of the functioning of commodity markets will be both a major formal and an organisational challenge for market participants and also a catalyst for new areas of risk for these companies. In addition, the limitation of the possibility of hedging - as a result of the entry into force of the new regulatory framework - can boost a market risk, and consequently create a systemic risk in other areas of the financial market than originally considered to be exposed to an increased risk of this type. Moreover, the limitation to only to short-term transactions outside the financial markets may have an adverse effect to the finan-cial results of power companies and, in consequence, to their financial standing, due to the increased market risk.

W artykule podjęto próbę przybliżenia obowiązków, jakie w zakresie handlu derywatami towarowymi nakłada na spółki obrotu rozporządzenie MAR. Poruszono w nim kwestię wpływu rozporządzenia MAR na rynek towarowy i relacji tego rozporządzenia do pozostałych regulacji mających wpływ na rynek energii i gazu (REMIT, EMIR, MiFID II). Przedstawiono wątpliwości i konsekwencje skutków tak ukształtowanego zakresu przedmiotowego regulacji. Zasygnalizowano także zagadnienia związane z planowanym harmonogramem wdrażania rozporządzenia MAR, jak również wyzwania dla podmiotów działających na rynku energii.

The aim of the paper is to present the impact of the Regulation on market abuse (MAR) on duties placed on companies trading in commodity derivatives. It also tackles the issue of the influence of the MAR Regulation on the commodity market and its relation to other legislation regarding the energy and gas market (REMIT, EMIR, MiFID II). The paper discusses also the precariousness and consequences of such legislative scope. Moreover questions are posed regarding the planned implementation schedule for the MAR Regulation as well as challenges for entities active on the energy market.
