The aim of this work is to provide some important morphological, ecological and reproductive features of 8 polyclad species from Tunisian waters belonging to Acotylea: Echinoplana celerrima Haswell, 1907, Leptoplana mediterranea (Bock, 1913), Discocelis tigrina (Blanchard, 1847) and Imogine mediterranea (Galleni, 1976) and Cotylea: Thysanozoon brocchii (Risso, 1818), Prosthiostomum siphunculus (Delle Chiaje, 1822), Yungia aurantiaca (Delle Chiaje, 1822) and Prostheceraeus moseleyi (Lang, 1884). New data on distribution of some species are added. Moreover, morphological data are provided for the first time in living specimens of D. tigrina. Based on our specimens, we confirm characterization of the two sub-orders Acotylea and Cotylea that have been already made in previous studies. Function of attachment organs in polyclads is discussed. On the other hand, data dealing with associated fauna are offered for all species. The two acotyleans E. celerrima and I. mediterranea were seen to cover their egg plates practicing thereby a parental care. This work could be a baseline for future taxonomic and behavioural investigations.

Al-Qusayr is located 40 km south of modern al-Wajh, roughly 7 km from the eastern Red Sea shore. This site is known since the mid-19th century, when the explorer R. Burton described it for the first time, in particular the remains of a monumental building so-called al-Qasr. In March 2016, a new survey of the site was undertaken by the al-‘Ula–al-Wajh Survey Project. This survey focused not only on al-Qasr but also on the surrounding site corresponding to the ancient settlement. A surface collection of pottery sherds revealed a striking combination of Mediterranean and Egyptian imports on one hand, and of Nabataean productions on the other hand. This material is particularly homogeneous on the chronological point of view, suggesting a rather limited occupation period for the site. Attesting contacts between Mediterranean merchants, Roman Egypt and the Nabataean kingdom, these new data allow a complete reassessment of the importance of this locality in the Red Sea trade routes during antiquity.

1. In their fundamental paper of 1949, Higman, Neumann and Neumann proved for the first time that a countable group can always be embedded in some 2-generator group: [1], Theorem IV. Two kinds of improvement of this result have recently appeared. In [4], Theorem 2, Dark has shown that the embedding can always be made subnormally. On the other hand, in [2], Theorem 2.1, Levin has shown that the two generators can be given preassigned orders m > 1 and n > 2; and in [3], Miller and Schupp prove that the 2-generator group can also be made to satisfy several additional requirements, such as being complete and Hopfian.

The author analysed the language of the first Polish translation of the eighteenth-century poem “Metai” [The Seasons] by Kristijonas Donelaitis, a Lithuanian Lutheran pastor. The translation was made in 1933 by a socialist activist and close associate of Józef Piłsudski, Kazimierz Pietkiewicz. The analysis showed that the language of the translation is peculiar. On the one hand, this peculiarity consists in refraining from archaizing the translation and the use of elements that are close to the translator’s style of social-political journalism (e.g., dorobkiewicz [vulgarian], feministka [feminist]), on the other hand, the presence at all levels of language of peculiarities characteristic for Kresy Polish language in both its territorial variations. These are generally old features of common Polish, the retention of which in the eastern areas of the Polish Rzeczpospolita was supported by the influence of substrate languages, later also Russian, or by borrowing. This layer was natural in the language of the translator, born in Ukraine, who spent part of his life in Vilnius, some in exile in Russia. This is the colourful linguistic heritage of the former Republic of Poland.

Although the intake of jack bean (Canavalia ensiformis (L.) DC.), an underutilized tropical legume, can potentially decrease the risk of several chronic diseases, not much effort has been directed at profiling the polyphenolics contained therein. Hence, this work aimed to identify and quantify the dominant jack bean polyphenolics, which are believed to have antioxidant and other bioactivities. Four major compounds were detected and identified as kaempferol glycosides with three or four glycoside units. Their structures were established based on UV-visible, 1D, 2D NMR, and HR-ESI-MS analyses. Specifically, kaempferol 3-O-α-l-rhamnopyranosyl (1→6)- β-d-glucopyranosyl (1→2)-β-d-galactopyranosyl-7-O-[3-O-o-anisoyl]-α-l-rhamnopyranoside was detected for the first time, while the other three compounds have already been described in plants other than jack bean. This new compound was found to have a higher α-glucosidase inhibition activity compared to acarbose.

Introduction. The article presents the results of research of the geographical vocabulary of the Shilan dialect, one of the Erzya-Mordovian dialects of the Samara region, common among Erzya population of Shilan village in Krasnoyarsk region. The dialect belongs to rare Mordovian dialects of the Samara Volga region that were formed in the region since the middle of the XIX century, and therefore its research is of extra interest. Materials and Methods. The research methods are determined by the purpose and objectives of the study. The analysis of the geographical vocabulary of the Shilan dialect is carried out with the involvement of relevant items made in other Mordovian dialects of Samara region, adjacent territories of neighboring regions, as well as other territories of settlement of the Mordovians. Data on geographical vocabulary of the dialect introduced into research for the first time. The main source materials for the article is based on field studies in Silane village during the field seasons in 2017 and 2020, as well as in other Erzya-Mordovian and Moksha-Mordovian villages of Samara region and adjacent territories in 2015 – 2020. Results and Discussion. The study showed that the geographical vocabulary of the Shilan dialect of the Erzya-Mordovian language is significantly different from the corresponding lexical clusters in other dialects of the Mordovian region, which can be explained by natural geographical conditions surrounding Shilan village and the original composition of this lexical cluster of Erzya immigrants who founded this village. Conclusion. The analysis of the geographical vocabulary of the Shilan dialect allowed, on the one hand, to identify specific features of this cluster that distinguish it from the corresponding materials of other Mordovian dialects of the region, and, on the other hand, to identify common isoglosses between it and a number of the Erzya-Mordovian dialects of the Samara Volga region.

Aloe vera (Aloe Vera L.) is a plant which commonly used by local people as moisturizer. The usage of aloe vera can be applied in form of peeled off gel mask with polyvinyl alcohol as gelling agent. The goal of this research is to determine the influence of increase of polyvinyl alcohol as gelling agent to the formulation of peeled off mask from aloe vera juice. The formulation was made in a few concentration, 10%, 12%, and 14% by adding 0,5% of aloe vera juice. After that, the formulation evaluated for 4 weeks about the organoleptics, homogenity, pH, drying time and viscosity. The date of pH test and drying time analyzed by using one way ANOVA statistically and then followed by Tukey HSD test and the viscosity analyzed by using Kruskall Wallis statistically which result in the significantcy less than 0,05 that mean there are difference in drying time and viscosity, on the other hand there is no difference in pH.

For the first time, in the article, Vladimir Titov’s letter (dated 12/24 February 1869) is published and commented. In the 1820s, in Russia, Titov was well-known as a writer and literature theorist, the author of a romantic novella The Remote House on Vasilyevsky Island (1829) close to Society of Lyubomudriye. The letter extracted from the archives of the National Library of Russia is addressed to Duke Vladimir Odoevsky whose relationship with Titov was friendly from the very beginning of their acquaintance. The letter focuses on Ivan Turgenev’s speech published in the first issue of Sovremennik and titled “Hamlet and Don Quixote”. Reacting to Turgenev’s article, Titov shortly and critically accesses the comparison concentrating mainly on the image of Hamlet and thoroughly expresses his opinion on the essence of his tragic state. Titov’s opinion is just the opposite of Turgenev’s complex and multidimensional interpretation. Having experienced the great impact of the philosophy of German idealism at the beginning of his career, Titov to a great extent idealizes Shakespeare’s character whom he long knows and whom he is clearly eager to vindicate. Meanwhile, Titov does not pursue the aim to absolutely advocate the romantic halo of Hamlet as a Titanic personality (grandiose intellect and scale of feeling) and to enact the tragic pathos of the inner fight only. Developing Goethe’s definition of the essence of the character’s inner conflict, Titov, on the one hand, approaches its real understanding underlying the prince’s necessity to stay in a derogatory position of a “pitiful semiclown, indecisive grouch and shred”. On the other hand, the assessment can not be absolutely objective because Titov wants to see Hamlet as a victim of the fatal fortune which turns him into a character of an almost classical tragedy of fate. Titov’s bright and developed reaction (in the document of private nature) to Turgenev’s article is attractive and important first of all for its vividly demonstrated novelty and creativity of the writer’s view, wideness and multimodality of the author’s perception of Hamlet’s image. For the first time, Turgenev gave a developed interpretation of Shakespeare’s image in the tale “Hamlet of Shchigrovsky Province” (1848). Continuing his searches in the area of “Russian” (or “steppe”) Hamlet, Turgenev creates moral and philosophical problems of the English tragedy in the crisis socio-historical and cultural atmosphere of Russia of the 1840s. However, the principles of the artistic generalization and the peculiarities of the new reading, not mentioned and not fully comprehended by his contemporaries, were surprising and rejected when the speech “Hamlet and Don Quixote” appeared, in which Shakespeare’s character is presented ultimately vividly and lively in the then current interpretation.

The paper examines two key novels by Sandro Veronesi, the modern Italian writer, Calm Chaos (2006) and Colibri (2020). Both novels were awarded Italy’s main literary prize, the Premio Strega, which is a unique precedent. The relevance of the article comes from the high demand for research on contemporary Italian literature on the one hand and from the novelty of the proposed interpretation for the novel Calm Chaos on the other hand. For the first time, the protagonist of Calm Chaos, Pietro Palladini, is presented not as a preacher of eternal values, returning the reader to the theme of knowing oneself and the surrounding world, but as a mad visionary with clear signs of psychopathy and schizophrenia. The analysis of Veronesi’s latest novel Colibri reveals the character’s evolution and the writer’s narrative manner. The theme of psychiatry in the life of a modern person appears to be one of the key ones in Veronesi’s work.

Employing Linda Hutcheon’s analogy between biological and cultural adaptation, this chapter analyzes how the survivors of the Roman-Gothic war in Shakespeare’s Titus Andronicus adapt figures and narratives of the survivor—or remnant—from Virgil, Ovid, and St. Paul as strategic models in the covert, post-war feud of the play’s action. Titus assumes Virgil’s model of the remnant as non-regenerative and stoic; Tamora, on the other hand, employs Ovid’s regenerative and vengeful model, and eventually converts Titus to it. Their violent conflict and absorption in their revenge plots form the conditions for the emergence of a different kind of remnant: the remaining Romans and Goths who, according to a Pauline model, form a new incorporated community. The formation of this community arguably speaks to the context of the Protestant Reformation in Shakespeare’s England, in which violent excisions were made in the name of a latter-day Pauline community.
