Topography and toponymies of Dunöyane were discussed in brief. The location of Lammas Islands was considered. The author recognized it as a trace of discovery of Dunöyane by Hudson in 1607. Historical data on human activity in this region was presented with a closer look at the murder of 10 Russians in 1819 and at Norwegian economic exploitation in the 19th and 20th centuries.

Controlling low-temperature drying facilities which utilise nonprepared air is quite difficult, due to very large variability of ventilation air parameters - both in daily and seasonal cycles. The paper defines the concept of cumulative drying potential of ventilation air and presents experimental evidence that there is a relation between this parameter and condition of the dried matter (sewage sludge). Knowledge on current dry mass content in the dried matter (sewage sludge) provides new possibilities for controlling such systems. Experimental data analysed in the paper was collected in early 2012 during operation of a test solar drying facility in a sewage treatment plant in Błonie near Warsaw, Poland.

This article uses the model of dependency between centers and peripheries of scientific knowledge production to create a theoretical framework for investigating predatory journals. The framework is presented as an alternative to the dominant ways of the problem's characterization. Predatory journals are so far described mostly as a newly emerging phenomenon strongly connected with publishing in Open Access and fraudulent publishers. In this article, I argue that predatory publishers are recognized as illegitimate by the center of knowledge production. This geopolitically situated approach let me look more critically on the ways of assigning this illegitimacy. It also allows me to define the ostensible center and reveal a mechanism for functioning many journals accused of being predatory. The ostensible center is understood as an institution disseminating knowledge that is invisible or illegitimate to the center. However, at the same time some actors see an ostensible center as belonging to the center. The presented terms are analytical tools for further research that might enable us to get a wider picture of a modern global system of knowledge production and point out its antiegalitarian mechanism.

The paper is focused on automatic segmentation task of bone structures out of CT data series of pelvic region. The authors trained and compared four different models of deep neural networks (FCN, PSPNet, U-net and Segnet) to perform the segmentation task of three following classes: background, patient outline and bones. The mean and class-wise Intersection over Union (IoU), Dice coefficient and pixel accuracy measures were evaluated for each network outcome. In the initial phase all of the networks were trained for 10 epochs. The most exact segmentation results were obtained with the use of U-net model, with mean IoU value equal to 93.2%. The results where further outperformed with the U-net model modification with ResNet50 model used as the encoder, trained by 30 epochs, which obtained following result: mIoU measure – 96.92%, “bone” class IoU – 92.87%, mDice coefficient – 98.41%, mDice coefficient for “bone” – 96.31%, mAccuracy – 99.85% and Accuracy for “bone” class – 99.92%.

The purpose of this study is to answer the question of whether informatics is a field or just a discipline of knowledge. Analyzes of info-computer-based problems, consider that informatics in Poland should be treated as a field. It was emphasized that the English term computer science is only one of the informatics-oriented specializations. The word “informatics” can be associated much more often with terms; IT in the US and ICT in Europe except France, where l’informatique terminology is used). Which name to use since the narrow understanding of information processing and handling is losing its full potential for the right development. In practice, it means a reduction in undertaking ambitious tasks and the higher costs of its development. Social implications confirmed that, despite a lot of capable informaticians, Poland had not been seen (except for computer devices), the right development of informatics-oriented applications. Hence the essential general informatics oriented strategy is offered because the digital equipment-oriented strategy alone is not enough to apply in success looking ICT applications.

The situation of transsexual persons in Poland is not precisely known; there are only estimates determining the scale of the phenomenon. The lack of information fosters stereotypes and, not infrequently, injurious appraisal; fear of the unknown is also produced, and is gradually turning into widespread prejudice. A social analysis of the phenomenon of transsexuality is hampered by the predominance of the hetero-normative discourse, including in scholarly spheres. The basic issue addressed by the author is the acceptance of transsexual persons, viewed from the perspective of their own personal experiences. These observations concern both the sphere of personal life as well as functioning in the macro-social space (school, work, etc.). In each of these spheres, a change of gender produces complications with which transsexual persons must grapple as they strive to live in harmony with their psychologically intuited gender.

Abstract Using mobile devices such as smartphones or iPads for various interactive applications is currently very common. In the case of complex applications, e.g. chess games, the capabilities of these devices are insufficient to run the application in real time. One of the solutions is to use cloud computing. However, there is an optimization problem of mobile device and cloud resources allocation. An iterative heuristic algorithm for application distribution is proposed. The algorithm minimizes the energy cost of application execution with constrained execution time.

The paper presents the capability of applying selected modern remote sensing methods based on commonly available high spatial resolution MODIS images to fog and low layer clouds detection. Single spectral channel images, differential images and selected color compositions are analyzed for distinguishing the areas of the phenomena occurrence. Their internal structure and fog/cloud particles properties are assessed using brightness temperature and reflectance diagrams.

The paper presents key assumptions of the mathematical model which describes heat and mass transfer phenomena in a solar sewage drying process, as well as techniques used for solving this model with the Fluent computational fluid dynamics (CFD) software. Special attention was paid to implementation of boundary conditions on the sludge surface, which is a physical boundary between the gaseous phase - air, and solid phase - dried matter. Those conditions allow to model heat and mass transfer between the media during first and second drying stages. Selection of the computational geometry is also discussed - it is a fragment of the entire drying facility. Selected modelling results are presented in the final part of the paper.

The paper proposes a procedure which enables to determine selected geometric and operating parameters for twin-fluid liquid-to-air atomisers with internal mixing. The presented approach assumes that in order to ensure proper operation of an atomiser it is necessary to design its structure and flow parameters in such a way so that the flow inside the mixing chamber has a dispersive character. In order to calculate a required exhaust cross-section for the analysed atomiser, conditions within the exhaust plane: pressure, density and outflow velocity were estimated. In order to determine diameter and number of orifices supplying the liquid to the mixing chamber of the investigated atomiser type, a multi-parameter analysis based on numerical fluid mechanics was performed. The final part of the paper presents selected results obtained from experimental stand measurements made on an atomiser designed according to the presented procedure.

The 2014/2015 revolution at the Kiev Maidan (and elsewhere in Ukraine) made a wide-ranging impact on the literature. In this paper I analyse diaries devoted to the events of the dignity revolution. I have selected three texts written in three different languages: “ Приватний щоденник ” by Marija Matios (in Ukrainian). “ Дневник Майдана ” by Adrjej Kurkov (in Russian) and “Ogień Majdanu. Dziennik rewolucji 22.11.2013– 22.02.2014” (in Polish). These texts are highly interesting mostly because they allow looking at the Maidan through the eyes of witnesses. Because of that we do not receive mere facts, but a testimony which tells us most about the people involved, represented by the specific author reporting their experiences, impressions, emotions, and thoughts. It is characteristic for the personal document literature that it is positioned somewhere between the events being described and the internal experiences, judgements and preferences of the author. It is shaped by their knowledge, experience, and moral code. These texts often con- centrate on the fates of specific individuals, their behaviours, the reasons and consequences thereof. They differ both in terms of the form and the motivations of the authors. They are all, however, rather unique, because they speak of the events of most recent history which so violently cut through the daily lives of Ukrainian citizens.

Professor Mieczysław Chorąży, one of the most eminent Polish biomedical scientists, died on February 20, 2021 at the age of 95. He was bid farewell with military honors at the Powązki Military Cemetary in Warsaw. He was buried close to his comrades in arms from the 1944 Warsaw Uprising. Mieczysław Chorąży was born in Janówka, a small village in Podlasie, in 1925. His education was interrupted by the outbreak of World War II which took away his mother, who died of typhus. He then decided to become a doctor. He was a member of the Home Army and fought in the Warsaw Uprising as soldier (nickname “Grom”) of the Baszta Regiment. In 1951 he graduated from the Medical Academy in Warsaw and was ordered to work at the then State Cancer Institute in Gliwice where he remained professionally active until the very end of his life. Following scientific internships at McArdle Laboratory for Cancer Research in Madison and Sloan- Kettering Institute for Cancer Research in New York in the early sixties he developed a method for isolating metaphase chromosomes from murine lymphocytic leukemia cells, used in DNA uptake experiments. In the 70s, he studied repeating and unique DNA sequences, DNA transcription mechanisms, activity of RNA polymerases and inhibition of cancer cell replication. Together with Kazimierz Dux, he authored in 1973 the “Introduction to the biology of cancer”, which at the time was the most important work in the field in Polish scientific literature. Mieczysław Chorąży was an outstanding authority in the field of environmental
mutagenesis and molecular epidemiology. The results of his research on DNA and chromosome damage in people from industry-polluted areas aroused wide interest worldwide. His Laboratory of Environmental Mutagenesis showed aberrations in metaphasal chromosomes caused by air pollution and correlated DNA adduct levels with concentration of polycyclic hydrocarbons in the air, including known carcinogens. Professor Chorąży research team revealed distinctive spectrum of mutations in the p53 suppressor gene among the inhabitants of Upper Silesia and characterized gene polymorphisms that determine individual sensitivity to carcinogens and functioning of DNA repair system. In his late years, Professor Mieczysław Chorąży was passionate about systems biology, research into chaos and early life on Earth. He was the supervisor of 18 doctoral theses, and five of his doctoral students later became professors. In the darker times of Poland’s national past, thanks to his wisdom and foresight, contacts were maintained with eminent researchers abroad allowing many Poles to pursue training in the USA, France, Germany and elsewhere. At the Professor’s initiative young scientists from the countries that emerged after the collapse of the USSR were able to continue their research in Gliwice thanks to scholarship awards granted by EACR and NCI-NIH. Mieczysław Chorąży was appointed professor in 1983. He was a doctor h.c. of medical universities in Katowice and Białystok. Since 1986 he was a full member of the Polish Academy of Sciences. Professor was also the member of Polish Academy of Arts and Sciences, American Association for Cancer Research, European Association for Cancer Research, Polish Biochemical Society, Polish Cancer Society (president 1974–1978), member of the scientific councils of Oncology Center in Warsaw, the Institute of Immunology and Experimental Therapy in Wrocław, the Institute of Human Genetics, Polish Academy of Sciences in Poznań and the Center for Polymer and Carbon Materials in Zabrze. In recognition of his scientific achievements and involvement in social and educational activities, insurgent struggle and shaping patriotic attitudes, Professor Mieczysław Chorąży received numerous distinctions and awards, including the Order of the White Eagle (2017), Polish supreme distinction. He was then eulogized as the “…nestor of oncology in Poland, outstanding scientist, founder of the Polish school of cancer biology, Warsaw insurgent, social activist, teacher and moral authority”. Professor received also the Lux ex Silesia award (2018) in recognition to his lasting contribution to the protection of Silesian cultural heritage. Professor Chorąży always opposed imprudent demolition of the reminders of industrial past of Upper Silesia, advocated sustainable development, and protecting green areas. Among various talents, Professor Chorąży was blessed with a gift of painting. Some of his watercolors and sketches embellish today the hall of the National Institute of Oncology in Gliwice. But Mieczysław Chorąży, the true man of virtue, will be perhaps best remembered for his kindness and concern for others, which brought him respect and love. He will be missed by very many people from all walks of life. Honor to His memory!
