The article deals with the patterns of segmental adaptation of Polish voiceless affricates in initial and fi nal CC (consonant + consonant) clusters by native speakers of English. The data have been collected in an online loanword adaptation experiment in which 30 native speakers of Southern British English reproduced Polish words containing such sequences. The major problem posed by the data is the divergent adaptation of the post-alveolar /͡tʂ/ vs. the pre-palatal /͡tɕ/, with the former substituted mainly with the coronal plosive [t] and the latter realised as the palato-alveolar affricate [͡tʃ]. It is argued that these patterns of nativisation are due to the highlyranked IDENT-IO[dist] constraint, which militates against the modifi cation in the value of the feature [distributed]. Furthermore, it is demonstrated that the experimental results provide evidence in favour of the fundamental assumptions underlying the phonological approach to loan assimilation, namely the phonological input view as well as the faithful perception view.

This paper presents the results of an experimental study and
mathematical modeling of the effect of dynamic instabilities on the condensation phase transformation of the refrigerants homogeneous R134a and its replacement in the form of isomers R1234yf and R1234ze and R404A or R507 and R448A in pipe mini-channels. In the case of homogeneous chlorofluorocarbons (CFCs), it is the 1234 isomers that are envisioned as substitutes for the withdrawn ones with high ozone depletion potential and global warming potential. For zeotropic and azeotropic mixtures, for example, these are R507 or R448A. The paper presents a dimensional analysis procedure based on the Buckingham Π theorem to develop a regression velocity model of pressure dynamic instabilities. The experimental part of the work was carried out with the use of tubular mini-channels with internal diameter 1.40–3.3 mm.

Pain in the masticatory muscles or temporomandibular joints may in some cases be a symptom of other afflictions occurring in this region. The aim of the study was to present the differential diagnosis of temporomandibular disorders (TMD) and other diseases in the craniofacial area, based on review of the literature. Using the key words: “differential diagnosis of TMD”, “pain of non-dental origin” and “chronic orofacial pain”, PUBMED and Scopus databases were systematically searched for articles in English from 2005 to 2020. Additionally, the PUBMED database was supplementarily reviewed using the keywords “Lyme disease orofacial symptoms” for the English-language articles published in the years 1996–2020. Out of 445 publications from PUBMED and Scopus databases as well as other sources, 57 articles describ-ing the pathogenesis and characteristic symptoms of diseases that may cause pain similar to that occurring in TMD as well as diagnostic methods used in differential diagnosis of TMD were selected for analysis. Dental and jawbones-related conditions, ear and maxillary sinus diseases, as well as ailments of neuro-pathic and vascular origin, were taken into account. Neoplastic processes taking place in this region and less often occurring diseases caused by viruses, bacteria and parasites were also described. Conclusions. Correct diagnosis of temporomandibular disorders is based on medical history and thorough physical examination, as well as results of additional tests. Pain localized in the head and neck structures may have diverse, sometimes complex aetiology, and may require multidisciplinary treatment. Observation of the patient’s behaviour and — in selected cases — the results of additional laboratory tests, also play a sig-nificant role.

This text is devoted to selected questions on the border of the ethnography of Łódź and research into women’s issues, and thus joins the trend of women’s urban anthropology. The author reinterprets selected sources, such as various types of writings and field materials from the archives of the Institute of Ethnology and Cultural Anthropology of the University of Łódź. Her aim is to reconstruct the local ‘herstory’ from the ethnographic-anthropological perspective. She therefore looks at certain aspects of the life of textile workers and locates them in the context of the perceptions of femininity and the work ethic around which Łódź’s image (stereotypical and auto-stereotypical) was created.

The demand for a net reduction of carbon dioxide and restrictions on energy efficiency make thermal conversion of biomass a very attractive alternative for energy production. However, sulphur dioxide emissions are of major environmental concern and may lead to an increased corrosion rate of boilers in the absence of sulfatation reactions. Therefore, the objective of the present study is to evaluate the kinetics of formation of sulphur dioxide during switchgrass combustion. Experimental data that records the combustion process and the emission formation versus time, carried out by the National Renewable Energy Institute in Colorado (US), was used to evaluate the kinetic data.

The combustion of switchgrass is described sufficiently accurate by the Discrete Particle Method (DPM). It predicts all major processes such as heating-up, pyrolysis, combustion of switchgrass by solving the differential conservation equations for mass and energy. The formation reactions of sulphur dioxide are approximated by an Arrhenius-like expression including a pre-exponential factor and an activation energy. Thus, the results predicted by the Discrete Particle Method were compared to measurements and the kinetic parameters were subsequently corrected by the least square method until the deviation between measurements and predictions was minimised. The determined kinetic data yielded good agreement between experimental data and predictions.

The article is titled “The symbol of the serpent in the Apocalypse of St. John”. Its aim is an exegetical analysis of the term “serpent” (ὄφις). The expression appears in Rev 9:19; 12:9; 20:2 and 12:14-16. In Rev 9:19 snakes are a symbolic element of a cavalry that realizes God’s plan. In other texts the serpent is a symbol of Satan. In Rev 12:9; 20,2 appears the title “the ancient serpent” referring to the biblical story of Gen 3:1-24. It is emphasized that Satan is the tempter. In Rev 12:14-16 the term “serpent” is used as a synonym for the dragon. It is possible that the symbolic scene of aggression towards woman expresses a destructive satanic action against the Church. We also ask a question how much the apocalyptic dragon (δράκων) is a serpent. In the course of exegetical analysis we have paid attention to two perspectives. The first is a historical and religious background of the serpent symbol in Rev. The second is original theology of Rev. One of her basic features is very rich symbolism. The author of Rev. refers to the past, but introduces a new, original content.
