Ore and non-ore mineralization in cracks filled with hydrocarbons in the dark grey Upper-Devonian limestone has been found in the Józefka quarry of Upper Devonian limestone and dolomite near the Górno village near Kielce at Holy Cross Mts. Poland. Hydrocarbons in the liquid form and iron and copper sulphides appears hear in the fault zone as joints filling. The wall rocks are impregnated by hydrocarbons giving them black color. Hydrocarbon impregnations appears also following the bedding planes The coexistence of ore mineralization and hydrocarbon suggests their common origin and migration from deep-seated sources, that may be the Silurian Ordovician or Lower to Middle Devonian black shales. The metallic-hydrocarbon compounds were suggested as metals carrier.

O tym, jaką przyszłość przewidywał Lem, przed czym przestrzegał oraz czy nadal pozostaje autorem nierozumianym, mówi prof. dr hab. Jerzy Jarzębski z Uniwersytetu Jagiellońskiego w Krakowie i Państwowej Wyższej Szkoły Wschodnioeuropejskiej w Przemyślu.

Ludzie łączą moje nazwisko z pierwszą transplantacją serca w Polsce. Ale wiem, że gdybym ja nie spróbował, to może cztery, a może pięć lat później inni zrobiliby tę operację. Jestem natomiast przekonany, że nikt nie zająłby się tworzeniem polskiego sztucznego serca. Gdybym nie walczył o stworzenie tego urządzenia, dziś kilkaset osób już by nie żyło, bo nie byłoby sztucznych komór, które uratowały im życie i zdrowie.

O działalności Polskiego Instytutu Studiów Zaawansowanych, który rozpoczął działalność w strukturach Polskiej Akademii Nauk 2 stycznia, mówi jego dyrektor prof. Przemysław Urbańczyk

The purpose of the study is a synthetic presentation of the development of children’s magazines in Poland from their creation to the end of World War I. The main focus of interest and research are magazines for younger and older children (up to 15 years of age) published in the Polish language across the ethnic and historical Polish territories. Periodicals published in this area in other languages (German, Russian, Belorussian, Ukrainian, Lithuanian, Yiddish, and Hebrew), one-days and calendars, school magazines, scouting and ethical magazines, and of course youth and student press were omitted. In the course of the research, it is established that 177 titles addressed to young recipients appeared in the examined period, 25 of which were published in the years 1824–1863, and 152 in the subsequent period.

The aim of this paper is to partially capture the state of theoretical debate amongst Polish historians on their own discipline in the second half of 20th century. To achieve this we analyse the content of the first twenty five volumes of journal Historyka published in the period when Celina Bobińska was its editor-in-chief (1967–1995). We assume that Historyka – the only journal dedicated to the theory of history and history of historiography – was situated in the centre of exchanges on academic historical practices. We do not treat its content as a reflection of contemporary studies in the theory of history, but as a dominant position in the self-understanding of the discipline competing with other utterances. The paper is a reconstruction of this offer, which is composed of the definitions of subjects of historical studies, descriptions of productive methods, hierarchy of masters of historical writings and their influential books.

The objective of this article is to describe the main characteristics of ‘football field’s anti-Semitism’, to understand its main causes, and to answer the question of whether anti-Semitism among football fans constitutes a symptom of one of the kinds of anti-Semitism discussed in the literature of the subject, or is its own kind of phenomenon. Based on reports of racism in Polish and Ukrainian stadiums, press articles, internet material, and in-depth interviews with fans of the Cracovian team Wisła, the authors conclude that football field’s anti-Semitism is a specific type. Even though footballs fans use content characteristic of modern or contemporary religion-based anti-Semitism, the addressees of their hatred are not followers of Judaism, members of the Jewish ethnic group, or the state of Israel, but fans of the opposing teams. Anti-Semitic incidents recur in places with a long history of Polish-Jewish coexistence, where the resulting antagonisms have been retained till today. The figure of the ‘Jew’ appears to be an effective, historically tested, method of showing contempt—the fans make use of the available content to insult their rivals.

After World War II, sexology developed in Poland as a holistic discipline embracing achievements in medicine, psychology, sociology, anthropology, philosophy, history, and religious studies. Sexuality was perceived as multidimensional and embedded in relationships, culture, the economy, and society at large. This approach was fundamentally different than the biomedical model, which started to develop rapidly in the United States after Masters and Johnson’s Human Sexual Response. The author discusses the impact of the two different models of sexology on the understanding of gender, while also considering the influence of economic and political factors (capitalism and socialism) on the development of scientific knowledge.

The article is an attempt of providing basic information on the Polish Register of Ships – (rejestr okrętowy), its legal principles, construction and mode of operation. The text is by no means a comprehensive legal analysis of this institution – such a study would have necessitated much more time and effort, but it is rather a synthetic guidance on how the register is designed, how it works, or at least how it should have worked and what sort of purposes it primarily serves. The publication reflects a present status of legislation in Poland, i.e. the respective regulations of the Polish Maritime Code enacted in 2001. It should be noted that a draft of a new Polish Maritime Code has recently been prepared, that designs the Polish Register of Ships in a slightly different, more flexible and up-to-date, mode. However, at the moment, we are not able to predict when the new regulations might be enacted and become applicable. Polish maritime hypothecation and mortgage are subject to a separate study that shall be presented in the near future.

Relacje polsko-belgijskie to nie tylko współtworzenie instytucji europejskich czy relacje gospodarcze. To wielowiekowa przyjaźń dwóch społeczeństw rozmiłowanych w wolności. Taki był jeden z głównych przekazów kolokwium zorganizowanego z okazji 100-lecia stosunków dyplomatycznych między dwoma krajami. Spotkanie odbyło się w siedzibie ambasadora Belgii w Polsce 11 kwietnia 2019 r. Swoją obecnością uświetniła je minister Anna Maria Anders.
