From the announcement of the Independence by Ukraine in 1991 and signing many bilateral agreements with the Russian Federation on the state border, the joint use of the Azov Sea and the Kerch Strait, until the annexation of the Crimea in 2014, both parties did not manage to carry out maritime distractions on these waters, due to different positions. After the annexation of the Crimea, the situation became beneficial for FR, because in its hands there was a Kerch Strait and the Russian side started the economic blockage of Ukrainian ports on the Azov Sea. The Ukrainian site, wanting to increase the number of its ships in the Berdyansk base located on this sea, decided to move through the sea team consisting of 2 artillery cutters and a subsidiary (tug) belonging to the Navy of Ukraine. During the approach to Kerch Strait, an incident occurred on November 25, 2018 between Ukrainian ships and the ships of the border service of the Federal Security Service (shelling, detention of the ships, arrests and putting their crews before the court). The above action was inconsistent with international law violating Articles 32, 58, 95 and 96 of the Convention on the Law of the Sea from 1982. The International Tribunal for the Law of the Sea in its judgement ordered RF to give back the ships and send seamen to Ukraine. The warrant was performed partially: ships were returned, while seafarers returned as part of the exchange of prisoners between the parties. Currently, Russia continues to run the economic blockage of the Ukrainian ports, closing (due to military exercises) approaches to the Kerch Strait for ships and vessels of other countries. The current situation indicates that Russia implements its geopolitical goals and disregards the provisions of international law of the sea.

In the article the Slavic term * ǫb(ъ)lъ ‘source, spring; well’ is analyzed from the point of view of its word-formation and etymology. The discussion of preceding etymologies leads to the formulation of a new etymology, based on the internal analysis of * ǫ-b(ъ)lъ ‘source, spring; well’ as * n̥-bl̥o ‘unmuddy’ = ‘clear (water)’. The identified cognates in Baltic * balā, Germanic * pōla-, and possibly Continental Celtic * bolā, all ‘swamp, marsh’, imply the initial, ‘non-Indo-European’, * b-. Finally, it is tested, if the etymon could represent an extension in -l- from the root * gu̯ebh- ‘marsh, swamp’ in the zero-grade of ablaut. The answer is ‘yes’.

This article discusses the role of the illustrated women's magazine Bluszcz [Ivy] in shaping and stimulating its readers' social and political engagement throughout the interwar period, from its relaunch in 1921 until 1939. Addressed to educated, middle-class women, it strove to raise their awareness in the wake of the women's enfranchisement act of 1918 and inspire them to participate in public life, to energize the local community, and to organize and promote various forms of social work.

The runoff coefficient is one of the fundamental hydrological characteristics of a catchment. It indicates a share of the precipitation water that runs off from the catchment.

The results of the runoff coefficient calculation based on measurements carried out continuously in the Cerhovický Stream catchment over a considerable period of time, i.e. from 1988 up to 2006 are presented. The precipitation and runoff data in the catchment were used. Mean value of the runoff coefficient and the runoff coefficients for the agricultural and forest parts of the catchment are presented. The total mean runoff coefficient for the Cerhovický Stream is 0.19 with the standard deviation of 0.06. Mean runoff coefficient for the forest part is 0.13 and for the agricultural part – 0.24.

Differences between the years with a higher and a lower precipitation were followed as well. We also statistically evaluated possible hydrological changes caused by the construction of the highway and the market centre. For another possible explanation of quite high standard deviation of the mean annual runoff coefficient we followed the monthly runoff coefficient dependence on water temperature and of ground water table depth.

Inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis, despite the increasing incidence, still do not have a specific etiology. Diet seems to be an important factor, modifying the occurrence of the disease and its course. Diet can affect the symptoms of IBD both directly, e.g., by alleviating diarrhea, bloating and constipation, and indirectly by shaping the microbiota. Bacterial meta-bolites produced under the influence of supplied nutrients may contribute to the modulation of pro- and anti-inflammatory pathways, depending on the diet used. So far, IBD has been associated with weight loss and malnutrition. In recent years, a trend of sarcopenic obesity with concomitant malnutrition has been observed. The new phenomenon is called malnubesity. This work aims to review the most commonly used diets in IBD in order to evaluate them in terms of alleviating ailments, but also maintaining proper nutritional status and lack of obesity. Low-fiber, low FODMAPs, Mediterranean diet and Crohn’s Disease Exclusion Diet diet were considered. We assume that diet is modifiable factor that is related to nutritional status and healthy body weight. In addition, the current knowledge on the relationship between nutrition strategies, obesity and IBD will be demonstrated.

The paper was focused on the reconstruction of past-environmental conditions dynamics based on the geochemical characteristics of sediments filling kettle-hole located in the western part of the Kashubian Lakeland, North Poland). Stratigraphic variability of lithogeochemical constituents and a set of 13 elements (TOC, N, P, Na, Ca, Mg, K, Al, Fe, Mn, Cu, Ni, Zn) were applied for Holocene reconstruction of certain processes and conditions in the studied kettle-hole. The detailed geochemical analysis allowed us to identify 6 phases in its development: Masz-1 stage covering sedimentation of sedge-moss peat over melting dead ice at the turn of the Preboreal and Boreal periods; Masz-2 stage of the initial phase of lake development with deep-water sedimentation; Late Boreal and Atlantic stage Masz-3 related to sedimentation of lacustrine chalk; Subboreal stage Masz-4 representing the beginning of lake terrestrialization; Subatlantic stage Masz-5 of lowland bog, and Masz-6 stage covering final phase of peatland evolution due to human activity. Principle component analysis highlighted the importance of two major factors controlling the geochemical variability of the studied sediments. These are the varied origin of supplying water reflected in the sedimentation of organic-calcareous sediments (PC1), and oxidative-reduction conditions determined by water level fluctuations (PC2).
