Cyto- and genotoxic effects of Actellic 50 EC and Rival pesticides on cells of Allium cepa L.
(Plovdiv University "Paisii Hilendarski", 2026-06-22) Stoyanov, Ivan; Vasileva, Penka; Staykova, Teodora; Popova, Teodora; Ivanova, Evgeniya
Pesticides are widely used synthetic compounds that can persist in the environment and pose significant risks to non-target organisms. Given their potential to induce genetic damage, their genotoxicity can be assessed through mutagenicity testing with suitable model systems. In the present study, the general toxic, cytotoxic, and mutagenic effects of two widely used pesticides, Actellic 50 EC (active substance pirimiphos-methyl) and Rival (active substance propamocarb hydrochloride), were evaluated using Allium cepa L. as a test model. Both formu-lations are used in agricultural practice to control insect pests, storage pests in cereals, and soilborne pathogens. The results demonstrated that Actellic 50 EC (at concentrations of 10 μg/L and 60 μg/L) and Rival (at concentrations of 40 μg/L and 80 μg/L) exerted a clear cytotoxic effect, as evidenced by a reduction in the mitotic index. Their genotoxic potential was confirmed by the induction of a wide spectrum of chromosomal aberrations, including anaphase and telophase bridges, chromosomal fragments, lagging and vagrant chromosomes. In addition, a significant increase in micronuclei frequency was observed, further supporting the genotoxic effects of the tested pesticides. Further studies using additional biological models and molecular genetic approaches are needed to better elucidate the mechanisms underlying the toxic action of these pesticides.
Environmental risks from thermal power plants that use coal as raw material for a long time – a case study from Kosovo
(Plovdiv University Press "Paisii Hilendarski", 2026-09-11) Musliu, Adem; Shabani, Milazim; Baftiu, Naim
Air and water pollution, along with heavy metal contamination, constitute some of the most pressing environmental issues affecting Kosovo. In recent years, the overall environmental situation in the region has deteriorated due to increased construction, traffic, and industrial pollution. This includes emissions from power plants and household heating during winter. Integrating sustainability into strategic energy planning is imperative for security policies and is well within the reach of emerging economies like Kosovo. The outdated technology and lack of effective regulations for air emissions from the two thermal power plants - Kosova A and Kosova B - have led to significantly higher stack emissions compared to coal plants in Western Europe. The specific impacts on vulnerable populations, such as children, the elderly, and those living close to the Obiliq power plants, have not been adequately studied. The construction of the new coal power plant - Kosovo C, represents a step forward in the energy sector but raises concerns about carbon dioxide emissions as a greenhouse gas pollutant. Currently, most energy production in Kosovo relies heavily on water usage across various power plants. Efforts are being made to reduce the environmental impact of Kosova A and Kosova B by decreasing dust, sulfur dioxide (SO2), and nitrogen oxides (NOx) emissions. It is crucial to shift towards producing green energy through sources like solar, water, and wind power to significantly mitigate these environmental challenges.
Amulets and Apocryphal Prayers in Bulgarian Literature and Culture
(Plovdiv University Press, 2025) Adinolfi, Roberto
Apocrypha have been a part of Bulgarian literature since its earliest stages and include apocryphal prayers, which are often contained in amulets. There are prayers against several kinds of illnesses, misfortunes, evil beings, and, generally against threats to human prosperity and well-being. Following a tradition from ancient times, in these prayers and incantations we can find large narrative parts, which at times bear similarities to folk tales. This is the case of the prayers of St. Sisinnius. Several of the apocryphal prayers are found in texts from different epochs; for instance, one should think of the letter of King Abgar to Jesus, excerpts of which can already be found in lead amulets from the 10th century, but it is also part of the first Bulgarian printed books. Today’s folk rituals share similarities with Medieval prayers. This paper focuses on the analysis of some apocryphal motifs through the centuries.
Transonimized Hydronyms in Bulgarian and Croatian
(Plovdiv University Press, 2025) Gola-Żurek, Jolanta
The article is devoted to the phenomenon of transonymization in two Slavic languages: Bulgarian and Croatian. The transition of one category of proper nouns to another affects many areas of life (the adoption of transferred names or zoonyms, anthroponymic names in the form of toponyms, the giving of personal names to commercial and service establishments or products, etc.). This process consists in the conversion of a proper name from one category into a proper name from another category, thanks to which transonyms are created, which are new, secondary proper names. An example of this is the transformation of the name of the Danube River into the name of the Bulgarian cream Danube, the Danube hotel in Croatia, or Danube Street in Krakow. The article examines the process of transonymization as a way of creating and maintaining Bulgarian and Croatian proper names in the urban space of the two Slavic countries, and presents the mechanisms of name-forming processes, the study of which could be continued and expanded in other Slavic languages.
Between Resentment and Nostalgia: Sketches on the Literature of Bulgarian Jews in Israel
(Plovdiv University Press, 2025) Mikulecký, Jakub
The Bulgarian-Jewish literature written and published in Israel from 1948 to 1989 remains an almost unexplored phenomena in the contemporary Bulgarian historical discourse. This article focuses on the interpretation of selected literary texts (poetry novels, and short stories), with particular attention to the poetics of nostalgia and, especially, to the relationship between nostalgic lamentations and traumatic memory, as the memory of Bulgarian Jews oscillated precisely between these extremes of remembering. The article examines texts by the following authors: Albert Mihael, Shlomo Kalo, Tilda Levi, Albert Varsano, Albert Levi-Pepo, Yona Schwarz, Edi Arueti, Aaron Assa, Salis Tadzher, and Moni Papo. Within mainstream Israeli culture, the works of Bulgarian Jews represent a distinctive subculture, bearing a unique language and cultural identity that reveals a specific historical memory.
