Aluminum profiles play an important role in civil engineering (facades, walls with windows) as well as in mechanical engineering (production lines, constructions of 3D printers and plotters). To ensure quick assembly, disassembly or changed the dimensions of constructions it is not possible to use such methods as welding, adhesive or riveting joints. The solution may be to use the so-called “popular lock”. It is a mechanism, the closure of which is caused by tightening of the conical screw, joining the “T” profile in the node. In order to properly design using the presented type of connection, it is necessary to know its strength and stiffness both in simple and complex loads states, also including imperfections. In the literature there is no information about the operation of the construction node with the so-called “popular lock”. The paper presents the results of experimental tests for connections subjected to uniaxial tensile test, paying special attention to the defects that may appear during the assembly. In the next step, a 3D solid connection model was created. Numerical simulations were performed in the Abaqus / Explicite program for both uniaxial tensile test and bending tests in two planes. Limit values of loads above which there is a plastic deformation of the material were determined. Determination of stiffness and strength of a single node allowed to make a simplified connector model. Using the numerical model, the analysis was performed taking into account the influence of imperfections on the work of the entire connection.

Focusing on the period of unprecedented infl uence of popular science in Yugoslavia following the Second World War, the article examines a combination of top-down and bottom-up approaches to linking science and Marxist philosophy of science against the backdrop of the dramatic political and cultural changes that were taking place in early socialist Yugoslavia.

Popular science magazines published in Poland between 1758 and 1939 are an important resource for all kinds of research including interdisciplinary analysis as well testing new methodological approaches. They provide insights into the changing understanding of science and its social functions, the status of the scientist, models of popularization of science, the channels and forms of communications, techniques of construction of the popular science text enhanced with graphics and illustrations.

The text was created on the basis of interviews with Caltech scholars (Pasadena, USA) in 2018. The talks concerned various contemporary theories of biogenesis and the role of their philosophical premises. The researchers also addressed the issue of popularizing science. The worldview is shaped (and established) by popularizing publications. They also answered the questions how their personal beliefs influenced on research.

The concept of city has got broad analytical perspectives, one of them are: the structural perspective, sociological, psychological, political, cultural, industrial and also the pedagogical perspective. In opposition to the concept of city is the concept of countryside, within which the concept of nature is regarded as an idyllic place, it is the place of childhood, the place of longing, it is the lost place that has been starting to go under the knife of time since the 20s of the last century. The apotheosis of the concept of city, that is being practiced by many artists, embracing the symbolics of the concept of city by mass culture and later by popular culture, causes the necessity to take the initiative of conducting the research that would attempt to establish the identity of the concept of city in modern culture. The article attempts to specify how the concept of city functions in popular culture through the analysis of chosen texts in popular music, starting from the 50s of the XX century until the XXI century.

The text deals with the issue of “historical biography”. It aims to reconstruct the key concepts connected with the biographical publishing series “The Legacies of the progressive personalities of our past”. The text answers the question what conceptual framework surrounded and legitimised the edition.

Egyptian writer ʼIhsān ‛Abd al-Quddūs is one of the most prolific contemporary Arab writers and gained great popularity, especially in his country, but also all over the Arab world. The author deals with issues considered by society, including literature, taboos as the relationship between man and woman outside the context of marriage, the description of physical contacts, carnal and passionate love, prostitution, drugs, and the emancipation of women. In his stories he was interested in the feelings of the human being and in his relationship with the society. Al-Quddūs can be regarded as one of the most multifaceted intellectuals in the whole Arab world: in addition to being a writer and journalist of great popularity, he also occupied a prominent place in Egyptian cinema. ʼIhsān ‛Abd al-Quddūs was a provocative artist of great popularity in his time, but little known in the West, because of the scarceness of translated texts. Through the translation and analysis of his works it is possible to open up a wider glimpse into the knowledge of contemporary Arab literature.

The article attempts to prove that Darwinism in popular culture plays a role of a theory of everything. Bestselling authors of popular science such as Edward O. Wilson, Richard Dawkins and Bill Bryson have acquainted general public with the theory of evolution, and its newest facet — the Modern Synthesis. Darwinian paradigms, as defined by Thomas Kuhn, are also used in popular books on cosmology, sociobiology, psychology, and religious studies. Moreover, the Darwinian grand narrative of evolutional history shapes the way in which contemporary mass culture presents the history of our planet in numerous educational TV series. Last but not least, Charles Darwin himself has recently become a popular icon and the story of his life is remade in a growing number of fiction and non-fiction books and movies.

Marta Wrzosek from the Faculty of Biology, University of Warsaw talks about the fascinating and complex world of fungi and examines the complicated role of language in science popularization.

This article outlines the rise and development of popular science periodicals in Poland from the 18th century until 1939. Their history begins in 1758 with the publication of Nowe Wiadomości Ekonomiczne i Uczone [Latest Economic and Learned News]. Our corpus includes 128 periodicals representing a great diversity of formats and content.

This article combines a general introduction to the crime fi ction of Walery Przyborowski with a study of the structure of the plot of his novels. The analyses of ten of his novels conclude with a typology of their narrative schemes, shown in the context of certain invariant patterns and the conventions of related literary genres. While the main objective of this study is to outline the structure of crime story and the social issues depicted in Przyborowski’s crime fi ction, it also pays some attention to the ways in which it refl ects his concerns about contemporary life and the condition of Poland under foreign rule. Basically, Przyborowski’s formula is to make use of the staples of the genre – mystery, adventure, romance – and the techniques of the popular novel. Moreover, his novels, like all of the 19th-century crime fi ctions, are clearly indebted to the conventions of the historical novel.

Twentieth-century historians of Polish literature (e.g. Henryk Markiewicz and Grażyna Borkowska) unanimously agree that Waleria Marrené-Morzkowska was at best a second-rank writer. It seems that such negative opinions are founded, fi rst of all, on the critics’ low view of her favourite genre, the popular romance; and secondly on a critical survey of her work written in 1966 by Irena Wyczańska for a multivolume Guide to Polish Literature of the 19th and 20th Century (Obraz literatury polskiej XIX i XX wieku). This article attempts to revise the established view of her fiction by analyzing some of works, i.e. two novels, Leonora’s Husband (Mąż Leonory, 1883) and The Little Blue Book (Błękitna książeczka, 1876), and the short story A Duplex Woman (Dwoista, 1889). This reappraisal draws on the favourable assessments of her work of the first generation of her readers, among them writer Teodor Jeske-Choiński, literary historian Henryk Galle and Piotr Chmielowski, a leading literary scholar of the late 19th century. In their view her work rose above the level of run-of-the-mill romances and didactic fi ction thanks to her skill in combining the conventions of the realist novel with plots of popular romance.

Polish popular-science periodicals have not yet been researched in terms of their overall graphic design and layout. Undertaking an in-depth assessment of this particular aspect was intended to follow the development of graphic design in the periodicals published on the Polish lands throughout the period spanning 1758–1939, with a view to identifying the most characteristic components that stood for overall visual appeal of specific publications, whilst pondering overall aesthetic and educational value of diverse illustrative material they offered to their readership. The article presents an outline of research into the graphic design of fifty such periodicals, highly representative of a popular-science genre. Comprehensive research results along with the accompanying factual material and tabularised data, which might well prove of some consequence in further comparative research, are available in a book format.

This article examines three aborted publishing projects involving popular science magazines from the early 19th century, two of them in Cracow, one in Kalisz. Their history has been reconstructed thanks to the publishers' prospectuses found in collections of the Jagiellonian Library.

This paper examines the coverage of women’s health issues, preventive care and prophylaxis in 19th-century Polish popular medical periodicals, in particular Dziennik Zdrowia dla Wszystkich Stanów [ Journal of Health for all Social Classes] (1801–1802), Przyjaciel Zdrowia [ Health’s Friend] (1861–1863), Zdrowie [ Health] (1877/78–1880), and Lekarz [ The Physician] (1903/04–1904/05). The authors of this study try to find an answer to the question whether those periodicals did succeed in giving women’s health issues the rank and status warranted by their significance.
