The emergence of life on Earth and its almost infinite diversity, reflected by a myriad of living organisms, are among the dilemmas that have forever fascinated scientists and philosophers. Today, we are still not able to determine what exactly initiated the chain of events leading to the rise of life – the mechanism of replication of initial structures or perhaps the occurrence of first metabolic reactions. Further approximations of these issues shall probably constitute an overwhelming driving force for future development of life sciences.

The article is a contribution to the methodology of reading and interpreting Dostoevsky’s famous novels. It owes its genesis to the refl ection upon the evolution of literary theory discourse in XX century and upon transformations in global (mainly Russian and Western) reception and modes of interpreting the oeuvre of the great Russian artist. The aim of the text is to prepare ground for reorienting Polish “dostoevskology” from the dominant reconstructive course onto the more creative, interpretative one. The order of my inquiries presents itself as follows. In the fi rst part of the article I focus on the questions of ideas, the protagonist and narrative techniques in Dostoevsky so that to highlight the specifi city of the writer’s approach to these issues. It will allow me to speak up for the minimum of methodological awareness which implies acknowledgment of the paradigm of polyphony, polysemy and complexity of Dostoevsky’s text. Perhaps it will also become possible to reveal some gaps in the hitherto existing state of research, debunk several stereotypes still functioning in Polish “dostoevskology”, and draw attention to still unrecognized interpretative clues in context of those crucial aspects of Dostoevsky’s work. In the second part I will reconstruct several most popular approaches to Dostoevsky’s text which differ in terms of understanding of what the relation between the reader and the text should comprise of. I will try to determine the benefi ts they can bring but also to sensitize to pitfalls they may entail. In the fi nal, third part of the study I will propose a project of a new interpretative approach which would rise to the challenge of Dostoevsky’s “spirit” as well as the spirit of his text the way it is construed by the most advanced contemporary critical studies and as I have learnt to perceive it.

The author presents the output of Eduard Makarian, a Russian cultural anthropologist, featuring his contribution to the problem of origin of culture. The development of Makarian’s scientific research has been presented from the understanding of systemic character of culture to the research on the origin of culture; from reflecting upon the first principles of culture development to the concept of system evolution as anthropogenesis, social evolution and cultural evolution, to the understanding of the origin of culture as a creative core of culture (cultural heritage, dynamics of cultural traditions, “tradition”–“change” dichotomy, hypothesis of “cultural genes”, etc.). The scientist moved from the issue of the origin of culture in the prehistoric times through the issues of permanent creation and dialectic self-revival of culture to the problems of culture in contemporary world. His research was of key importance for the establishment of philosophical and cultural approach in the research of the origin of culture in Russia.

Per- and polyfl uoroalkyl substances (PFASs) are human-invented chemicals that were created in the middle of the 20th century. They were synthesized for the fi rst time in 1949, and because of their exceptional surfactant properties, they have been widely used in many industrial applications and daily life products. The common use of PFASs resulted in their worldwide dissemination in natural environment. PFASs are reported to be ubiquitous in surface and drinking waters, but also may be present in soils, animals, milk and milk-products, plants, food. Contaminated drinking water and food are the most signifi cant exposure sources to these chemicals. Ingested PFASs are bio-accumulative and have adverse eff ect on health of humans as well as animal organisms. This paper reviews the most signifi cant information on the origin, properties, distribution, environmental fate, human exposure, health eff ects, and the environmental regulations on PFASs and summarizes the latest advances in the development of novel methods for the eff ective removal of these chemicals from the aqueous environment. Recognized (reverse osmosis, adsorption on activated carbon) and most promising developing removal methods such as adsorption on biomaterials (plant proteins, chitosan beds), mineral adsorbents (LDHs, hydrotalcite), ionexchange resins, and photocatalytic degradation have been emphasized.

Martin Heidegger in The Origin of the Work of Art (Der Ursprung des Kunstwerkes) developed a whole new way of thinking about art, going beyond traditionally understood aesthetics or even philosophy of art. Some of Heidegger’s thoughts, however, appear to be understated and only signal a huge complexity of both experiencing works of art and the very issue of the origin of the work of art. The analysis of the terms ‘dread’ and ‘eyeblink’ from Time and Being presented in this article complement and develop Heidegger’s ideas included in his essay. Linking art to these two crucial phenomena of fundamental ontological analysis of Dasein casts light on the status of art and its existential significance. The author aims mainly at demonstrating the aletheic connection (based on unclosedness) between the experience of ‘originary source’ of a piece of art and ‘dread’, and also, in conclusion, he points to the ‘event of Being’ as the essential, non-metaphysical origin of art.

This is an obituary of Harold Bloom and a brief review of his two books: The Western Canon and How to Read and Why, which were recently translated into Polish. It also outlines Bloom’s unique conception of literature and his praise of solitary reading.

In the magazine Unser Danzig published by ex-citizens of Gdańsk in the years of 1949–2008, one must pay attention not only to politically-engaged texts, but also to obituaries which present lives of the deceased and missing their lost fatherland. The aim of these obituaries is not only to inform about someone’s death, but also to acccept the regional origin of the deceased, which is presented by linguistic and paralinguistic means.

The article contains basic information about the recently identified Polish-Albanian glossary, and presents its content in an accessible form.

The aim of the article is to present the attestations of contemporary Polish surnames of Lithuanian origin which are absent from the dictionary of Lithuanian surnames (“Lietuvių pavardžių žodynas”, LPŽ), excerpted from the anthroponymic index card files that have been stored in the Lithuanian Language Institute in Vilnius and continually enlarged for several decades now. The files contain data excerpted from historical sources of the 16th to 19th centuries and consist of about 200,000 index cards (the actual number of excerpted anthroponyms is lower since some recur in various sources). Due to space limitations, generally only directly attested names have been included in the article, to the exclusion of those whose relationship with the researched name can be inferred rather than considered proven. Each listed attestation of an anthroponym (probably not in all cases an already established hereditary surname) is accompanied by information concerning its location and year (or time bracket), wherever available in the card index file. Given names or other details (e.g. the role of the person mentioned in documents, such as godmother in the data excerpted from baptismal registers) have only been included occasionally, if there was some reason to do so.

Blockchain is a technology, which could revolutionize many industries in the future. A system like that is based on a chain of blocks that is used for storing and transferring various data, forming a decentralized ledger. Although various fundamental projects based on the blockchain system in the energy industry are in their early stage of development, as well as other solutions, applications of blockchain technology in the broadly understood power engineering sector are considered to have a very large potential. This paper presents a brief description of the blockchain technology, its general operating principle and the possibilities it brings. The next section of the article contains a characterization of two exemplary and possible blockchain technology applications, which in the perspective of time may have a significant impact on the power engineering sector. The first solution is related to carrying out energy transactions, which could be conducted in an easy way directly between energy producers and consumers. Thanks to blockchain technology, this could lead to a partial decentralization in that area. The second proposed example concerns energy resources origin tracking, which would allow fixed origin attributes and parameters affecting the environment to be assigned to the generated energy. By implementing that solution, it would be possible to construct a fuel footprint of individual generating units. The article also mentions examples of other potential applications of blockchain technology in the power engineering sector.

O b j e c t i v e s: To identify tooth diseases as potential causative factors in the development of maxillary sinus lesions, with the aid of clinical examination combined with Cone Beam Computed Tomography (CBCT), in the patients with persistent sinus-like ailments, unresponsive to routine treatment offered by otolaryngologists.

M a t e r i a l s a n d M e t h o d s: In 44 patients with suspected odontogenic maxillary sinusitis, a dental examination with tooth vitality test was carried out, in conjunction with CBCT. The study involved 29 women and 15 men (age range 19–69 years, mean age 43 (SD = 13.9) years).

R e s u l t s: In 15 (34.1%) patients the odontogenic lesions were encountered in maxillary sinuses. A total of 33 causative teeth were identified, of which 13 (39%) were after root canal treatment (RCT). Only one of the teeth had a properly reconstructed crown, and only one tooth had the root canals properly filled-in. Most frequently, the lesions in the sinuses were attributed to the inflammation of periapical tissues; the first molar having been established as the most common causative tooth.

C o n c l u s i o n s: A detailed dental examination, pursued in conjunction with CBCT analysis, allow to diagnose odontogenic maxillary lesions. The incidence of long-term ailments originating in the maxillary sinuses should prompt a detailed assessment of the teeth, especially those after RCT.
