The aim of this article is to research the psychological trauma of a person who has experienced extreme events and gained psychotraumatic experience. Modern humanities understand the problem of injury in several aspects. One of the topical issues is the representation of psychotraumatic events through the involvement of aesthetic experience. The relevance of this paper is due to the fact that an important component of safe human life is to solve problems related to experiencing mental trauma and healing a person from it. The leading research method was the method of analysis of research sources. Also, in the research, the authors used the method of synthesis, observation, modeling. To describe the narrative of psychological trauma, the authors set out the theoretical foundations of the toolkit. The authors' view on the negative consequences of the traumas of war in their further psychological, physiological, and social development was presented. The main ways of reflecting individual and collective traumas were also analyzed, and artistic strategies of detraumatization were pointed out. As a result of the study, generalized conclusions were formed about the role of narrative practices in the formation of the historical and individual experiences of overcoming psychological trauma.

Following the so-called “special military operation”, which was in fact an open aggression against Ukraine, Russia was expelled from the Council of Europe. This step has significant legal consequences, including for the jurisdiction of the European Court of Human Rights. Meanwhile, many individual applications were filed with the Court, and Ukraine brought an inter-State complaint against Russia. Ukraine has also triggered the International Court of Justice. The Court has already ordered provisional measures. The ICC Prosecutor has launched an investigation into the most serious international crimes, war crimes, crimes against humanity, and genocide in Ukraine and delivered arrest warrants against the Russian President and his Commissioner for Children’s Rights. There is a serious discussion going on concerning the establishment of a special tribunal for the crime of aggression. This text deals with some aspects of the Russian “special military operation” cases before international courts. It attempts to identify what role the international courts may play in the new phase of the conflict in Ukraine and the extent and effect of their intervention, given the jurisdictional limitations and the inability to enforce judgments.

The aim of this study is to prove that the dynamic behavior of tensegrity grids can be controlled. This possibility is very important, especially for deployable structures. The impact the support conditions of the structure on the existence of the immanent characteristics, such as self-stress states and infinitesimal mechanisms, and consequently on the dynamic control, is analyzed. Grids built with the modified Quartex modules are considered. A geometrically non-linear model is used, implemented in an original program written in the Mathematica environment. The results confirm the feasibility of controlling tensegrity structures characterized by the presence of the infinitesimal mechanisms. In the case that the mechanisms do not exist, structures are insensitive to the change of the initial prestress level. The occurrence of mechanisms can be controlled by changing the support conditions of the structure. The obtained results make tensegrity a very promising structural concept, applicable in many areas when conventional solutions are insufficient.

The chemical composition of commercial thyme oils, freshly hydrodistilled EO (essetntial oil) from dried thyme herb and thymol, the main thyme oil constituent, were analyzed in the aspect of possible cytotoxic effect against MCF-7 breast cancer and normal L929 mouse fibroblast cell lines. Based on the GC-MS analysis, it was found that the commercial essential oils revealed similarities in their chemical composition. The content of main components such as thymol, linalool and α-pinene was almost equal. Interestingly, the EO obtained by hydrodistillation from Thymi herba showed considerable differences in the percentage content of some main constituents. The reason for the differences may be caused by the intraspecific chemical variability of T. vulgaris L. Four types of tested EOs can be classified as a ‘thymol’ chemotype, with thymol as the predominant compound. The thymol alone and the freshly hydrodistilled EO demonstrated the highest cytotoxic effect against used cell lines. The difference in IC50 values suggests more sensitive L929 cells are more sensitive in both the CCK-8 assay (except EOs Kawon) and the NRU assay.

The Reinforced Concrete (RC) beams containing Expanded Polystyrene Beads (EPS) and Palm Oil Fuel Ash (POFA) as sand and cement replacement with a percentage between 10% and 30% were studied in terms of load-deflection behaviour. RC beam’s size was 1000×150×150 mm and simply supported at spaced 750 mm apart. The 10% of POFA without EPS shows a slight increase which is 0.26% higher than normal concrete in compressive strength. The ultimate load and flexural performance of RC beams with EPS and POFA exhibited a decreasing trend. All beams’ ultimate load exceeds the design value. The cracks of the RC beam may be classified as vertical flexural cracks, and some of the cracks can be classified as shear cracks based on the crack angle. As the percentage of EPS and POFA increases above 20% for all specimens, cracking starts to change to shear cracking.

Regaining independence by each country (Tunisia, Morocco 1956, Algeria 1962) and the publication of relevant documents (codes of family law, constitutions) created opportunities to speak more widely about social and economic rights, or about political rights for women. However, the rights granted to women were characterized by the principle of inequality, especially in Algeria and Morocco. In this difficult and complex situation, the emancipation movement of women went through various phases. In Algeria, its strength began to appear at the turn of the seventies and eighties of the twentieth century and has been constantly increased. In Morocco, in principle, the awakening took place in the early nineties of the twentieth century. Women themselves played a significant role in the activities for emancipation, engaging in various undertakings, organizations and associations, and in activating Non Profit Organizations (Organisation Non-Gouvernementale -ONG) with women participation from the end of the 80s of the twentieth century, which, in its turn, created opportunities for legal reforms, which would not exist without activities carried out by various associations, including women’s associations. The Jasmine Revolution, also known as the Arabic spring, was initiated in Tunisia, and has had a significant impact on the contemporary activities of women.

The author of the article considers that the legislation of 20 December 1996 relating to ports and maritime landing stages regulates three groups of issues. The first chapter of the legislation is structural; the two remaining chapters regulate legal relations. The article analyses the regulations contained in chapter three of the legislation, and especially art. 8 which entitles the entity managing ports of fundamental importance for the national economy "to fix and collect port charges." The article presents the course of the case between the Managing Board of the Port of Gdańsk S.A. and the Northern Port Sp. z o. o. The case was heard before the District Court in Gdańsk (Doc. Sig. IX GC 1819/99). The subject of the claim was the port charges levied on the owners of loading equipment.
