Abstract In the Czech Republic, the program managing high radon levels in dwellings has existed for nearly 30 years. Although the recent history of radiation protection from naturally radioactive gas is quite well known, prior radon management is less understood. This article describes the history of natural radioactivity and its management from the Middle Ages, showing that Czech countries have a much longer and abundant history related to natural radioactivity.

The editorial series Bibliotheca Tessinensis, founded in 2004, is devoted to publishing the unknown or hardy accessible source documents related to the history of Cieszyn Silesia from the Middle Ages to the present, as well as the sources of universal significance, which are stored in Cieszyn Silesia and constitute the abiding component of the cultural heritage of the region. The title of the series harks back to the edition of the bio- and bibliographical materials, planned to be edited by Leopold Jan Szersznik (1747-1814); in the publishers’ intention it grounds the series in the historiographical tradition of the region, giving it also a supranational character and outreach. Accordingly, the Bibliotheca Tessinensis is being issued in two subseries – one of them (Series Polonica) published by Książnica Cieszyńska (the Cieszyn Historical Library), and the other (Series Bohemica) – by Ośrodek Dokumentacyjny Kongresu Polaków w Republice Czeskiej (the Documentation Centre of the Congress of Poles in the Czech Republic). The consecutive volumes of both subseries, issued independently of each other, depending on the organiza tional and financial possibilities of the publishers, are prepared according to the common editorial instruction, have the same layout, and are numbered sequentially within the whole series.

For more than twenty years, the Institute of Slavic Studies of the Russian Academy of Sciences celebrates the Day of Slavic Writing and Culture with a traditional scholarly conference.”. Since 2014, it has been held in the young scholars’ format. In 2019, participants from Moscow, St. Petersburg, Kazan, Togliatti, Tyumen, Yekaterinburg, and Rostov-on-Don, as well as Slovakia, the Czech Republic, Hungary, and Romania continued this tradition. A wide range of problems related to the history of the Slavic peoples from the Middle Ages to the present time in the national, regional and international context were discussed again. Participants talked about the typology of Slavic languages and dialects, linguo-geography, socio- and ethnolinguistics, analyzed formation, development, current state, and prospects of Slavic literatures, etc.

This chapter outlines the history of language construction, beginning with the earliest recorded examples of linguistic creativity and continuing with the first true constructed languages from the Middle Ages up through the Renaissance and Enlightenment, when language construction was guided largely by religious and philosophical concerns. The chapter continues by exploring more recent history, when language construction was guided more by practical goals to unite humanity. At the same time, language construction as an art form was also being developed, most notably by J. R. R. Tolkien, who set the stage for the modern era of artistic language construction requiring specialized knowledge, talent, and hard work. The chapter also discusses the emerging role of language construction as a tool for language revitalization and concludes with a summary of terms and concepts that are important to the study of constructed languages.

Since the avian bornavirus (ABV) aetiology of the proventricular dilatation disease (PDD) was proven in 2008, ABV has been detected in many avian species. The aim of the present study was to detect ABV antibodies in parrots in the Czech Republic and Slovakia. A total of 142 birds were examined, including 37 birds with symptoms typical for PDD, 54 birds without PDD symptoms, and 51 parrots without any clinical symptoms of PDD but originating from one flock with a proven history of PDD. Sera from 142 birds were tested using the enzyme-linked immunosorbent assay (ELISA) for detection of antibodies against ABV nucleoprotein p40. Of 142 serum samples, 71 were positive (50%) and 71 negative (50%). In a group of birds with clinical symptoms of PDD, 77.1% showed to be ABV positive, whereas in the group of sick birds without suspicion of PDD the percentage of positive birds was 31.6%. In the birds that had a cage mate that was positive for ABV or died with PDD, 42.9% were ABV positive. Of the parrots without PDD symptoms but originating from the flock with a recent history of PDD, 62.8% of the birds were positive for antibodies against ABV nucleoprotein p40. The results suggest that PDD is common and there is a high percentage of asymptomatic carriers of ABV in the breeding facilities of parrots in the Czech Republic and Slovakia.

ABSTRACT The article reports on a new sampling method and the archaeological context of cave drawings, which include the oldest currently known graffiti in the Czech Republic. Between 2016 and 2020, samples with a small amount of charcoal were taken from drawings found in Kateřinská Cave (Catherine’s Cave) of the Moravian Karst in the Czech Republic. A new gentle method of sampling charcoal from the cave walls was developed for the purpose of radiocarbon (14C) dating cave drawings of unknown age, while preserving the contours of the drawings. 14C analysis has provided data from four periods of prehistory and history: from the Neolithic around 5000 BC, the turn of the Neolithic and Eneolithic around 4300 BC, the Hallstatt Period from 800–450 BC, and also from the Middle Ages (13th century). The radiocarbon dates of the graffiti correspond to the dates of the pottery finds from the entrance portal of Kateřinská Cave, thus validating the dates and the sampling method.

In the second half of the first millennium CE, the Christian Middle East fractured irreparably into competing churches and Arabs conquered the region, setting in motion a process that would lead to its eventual conversion to Islam. This book argues that key to understanding these dramatic religious transformations are ordinary religious believers, often called “the simple” in late antique and medieval sources. Largely agrarian and illiterate, these Christians outnumbered Muslims well into the era of the Crusades, and yet they have typically been invisible in our understanding of the Middle East's history. What did it mean for Christian communities to break apart over theological disagreements that most people could not understand? How does our view of the rise of Islam change if we take seriously the fact that Muslims remained a demographic minority for much of the Middle Ages? In addressing these and other questions, the book provides a sweeping reinterpretation of the religious history of the medieval Middle East. The book draws on a wealth of Greek, Syriac, and Arabic sources to recast these conquered lands as largely Christian ones whose growing Muslim populations are properly understood as converting away from and in competition with the non-Muslim communities around them.
