Electron probe microanalysis of archaeological non-ferrous metal (using the example of finds of the 5th–6th centuries AD from the burials of the Varna burial ground)
Authors:   Udmurt Federal Research Center UB RAS, Sabirova Tatiana M. , Beltiukov Artemii N. ,   Udmurt Federal Research Center UB RAS
Published: April 2024

The article introduces into scientific circulation the first data on the composition of non-ferrous metals of the early Middle Ages in the territory of the river Cheptza. To obtain a comprehensive description of archaeological metal of the 5th–6th centuries samples of 55 items from 15 burials of the Varninsky burial ground were prepared. To conduct the study, a previously tested method of quantitative elemental analysis of the samples was used. The obtained data were entered into an analytical table containing the information on the percentage of components and data from archaeological finds. The analysis of the results revealed that in the 5th–6th centuries people used mainly multicomponent zinc-containing alloys for the manufacture of jewellery and costume elements. The formal approach to the classification of non-ferrous metal alloys was revised: in addition to bronze and brass, zinc-containing bronzes are singled out into a special category illustrating the numerous remelting of non-ferrous metals. Particular attention is drawn to the large number of things based on not copper alloy, but tin alloy. So-called prescription alloys with specified characteristics were identified in small quantities: "pure" twocomponent brass with a high zinc content was identified in only four samples, and bronze was represented by eight analysed samples. The first preliminary measurements illustrate that the population of the polomskaya culture mainly made necessary things from scrap non-ferrous metals and did not have the opportunity to obtain semi-finished products – ingots. The present investigation established the features of using electron probe analysis to study archaeological finds.
Numerical Modeling of the Two-Component Liquid Flow through a Pipe with a Static Mixer
Authors:   Udmurt Federal Research Center UB RAS, Koroleva Maria R. , Volkov Vladimir S. ,   Kalashnikov Izhevsk State Technical University
Published: April 2024

The effect of a stationary mixer on the mixing of the liquid components in a pipeline is investigated. The studied mixer is made in the form of perforated disks with different locations of holes relative to the center of the disk. The main attention is paid to the study of the two-component liquid flow containing equal proportions of water and oil in a pipeline channel equipped with a static mixer. To analyze the dynamics of the flow, mathematical models implemented in numerical methods and algorithms of the OpenFOAM libraries are used. The computational experiments carried out made it possible to obtain a detailed understanding of the structure of flows inside a pipeline with an installed mixer. In addition, the obtained results permitted the qualitative and quantitative evaluation of the processes of mixing and stirring of liquid components. In the present work a detailed study of the pressure losses along the length of the pipeline is carried out. The regions of local and linear resistance are identified. It is shown that the presence of a water component in the flow leads to an increase in resistance and depends on the type of disks used in the mixer. The results obtained allow us to conclude that the studied static mixer with perforated discs can be used to obtain a homogeneous oil-water suspension; however, it is most effective when working with mixtures with a high water content.
La métaphore comme exercice spirituel dans les écrits d’Hadewijch d’Anvers. L’épreuve d’une parole excédée
Authors: Raviolo Isabelle
Published: April 2024

Hadewijch d’Anvers recourt à la métaphore dans la langue poétique de l’amour. Mais, plus qu’à des images figurant quelque chose, c’est davantage « au bord du rien » qu’elle conduit le lecteur. Le poème se présente comme une expulsion vers le désert : « c’est du tout au rien que nous chasse l’amour ». L’abîme, « l’abîme sans fond », ou la noyade, exprimée par la « meule de moulin » incapable de « nager dans la rivière », ou encore la « nudité », renvoient à une expérience dans laquelle la conceptualisation est écartée. Cet « écart » est lui-même opéré par la métaphore, en tant qu’elle excède le langage.
Faut-il croire aux métaphores ? À propos du statut des créatures dans l’exégèse, la métaphysique et la théologie mystique de saint Bonaventure
Authors: Solignac Laure
Published: April 2024

Bonaventure, appelé le « Docteur séraphique », déploie une logique de la ressemblance dans laquelle le sens littéral est le lieu de transfert vers le sens spirituel. La métaphore, comme celle du « fleuve », de « l’huile » ou de « la vigne », est la figure de style par laquelle s’opère ce passage. L’exégèse se présente comme un exercice de décèlement de ce qui se trouve déjà là, mais de manière cachée. Le monde est un premier livre dont le livre des Écritures révèle le sens, tout en guérissant celui à qui il ouvre les yeux. Bonaventure prend son lecteur par la main, dans une « manuduction ». C’est à travers la puissance affective de la métaphore qu’est revisitée chez lui la translatio in divinis.
Uncanny and Ungrammatical Shudders: Edgar Allan Poe’s ‘Master Stroke of Cant’
Authors: Rolls Alistair
Published: April 2024

This essay argues that all detective fiction stems from an Urtext, The Murders in the Rue Morgue (1841), whose metaphysical credentials have been well established. Edgar Allan Poe’s tale founds the genre’s recurring instances of metaphysical convulsion. Thus, whenever that famous reflexive joke is trundled out, and a character marvels at the way that events happening in the story are more like detective fiction than real life, the text is in fact revealing (coyly, covertly but also brashly, overtly) its fundamental, metaphysical nature as simultaneously present and absent. By theorising such reflexivity as a shudder, this essay seeks to demonstrate, through various instances found in Agatha Christie’s novels, that detective fiction demands to be read critically from beginning to end, and not only for the apparent pleasures of solving the crime.
Frissons et considérations métaphysiques dans The Woman in White
Authors: Leroy Maxime
Published: April 2024

Cette étude propose une lecture du roman The Woman in White de Wilkie Collins à la lumière de textes de Paul Ricoeur. Partant d’une expression de Collins dans sa préface de 1860 sur les « considérations métaphysiques » suscitées par le roman, on montre la centralité des questions d’identité, de secret, d’origine du mal et de vérité, et le rôle du corps frissonnant comme médiateur entre sensation et pensée.
Métaphysique du roman noi
Authors: Tadié Benoît
Published: April 2024

En partant d’une définition de la métaphysique comme « science qui consiste à progresser de la connaissance du monde sensible à celle du suprasensible » (Kant), cette étude vise à montrer : 1) que le roman policier en général, en ce qu’il se fonde sur la question du meurtre, est un genre « métaphysique » ; 2) que le roman noir en particulier incarne cette progression « du monde sensible » vers le « suprasensible », débouchant sur deux grandes questions : le mal, la mort. L’analyse est développée à partir d'exemples empruntés au roman noir du 20e siècle : Dashiell Hammett, W. R. Burnett, William Faulkner, Raymond Chandler, Horace McCoy, David Goodis, ou encore William Hjortsberg. Elle dégage deux courants dans le genre : d’un côté, une « métaphysique de l'absurde » de l’autre, une « métaphysique de la chute ». On suggère en fin de compte que les interrogations de ces auteurs reprennent et prolongent, par le médium du polar, celles des grands auteurs classiques américains, Poe, Melville, Dickinson ou Henry James.
« Les corbillards invisibles qui passent furtivement le long des routes » : le monde des romans policiers de Henning Mankell
Authors: Bourguignon Annie
Published: April 2024

Cette étude traite des romans policiers de Henning Mankell. Elle rappelle d’abord ce qu’étaient les positions politiques de l’auteur, et s’intéresse ensuite à sa vision du monde. Celle-ci s’exprime à travers les paroles et les pensées du protagoniste Kurt Wallander, à travers l’image de la société suédoise présentée, ainsi que par la structure que Mankell donne à ses récits. Dans cet univers, la raison ne parvient plus à résoudre toutes les énigmes, sans qu’elle soit pour autant considérée comme impuissante. Le mal n’est pas non plus totalement vaincu, mais il est un peu battu en brèche. La nécessité de combattre le mal apparaît comme le résultat direct d’un appel à un sens moral basique spontané, commun à l’auteur et aux lecteurs, qui n’a pas besoin d’être explicité ou justifié. L’être humain tel que le voit Mankell s’avère incapable de maîtriser intégralement le monde, sans être totalement démuni face à lui.

Inclure les parents dans une prise en charge de type communication alternative et améliorée. Les apports du projet Tiwouh
Authors: Fage Charles , Maillart Christelle
Published: April 2024

Ce chapitre pose le contexte de la place des parents dans les interventions de communication alternative et améliorée (CAA) pour les enfants présentant un trouble du spectre de l’autisme (TSA). Appuyés par les résultats encourageants de la littérature quant au développement langagier des enfants lorsque les parents délivrent l’intervention, ces derniers voient leur rôle évoluer et se rapprocher de celui du professionnel de santé. Des programmes d’entrainement ont donc été développés pour former et accompagner les parents et, pour lever certains freins à leur inclusion, parfois à distance. Dans ce contexte, nous présenterons un projet de CAA basé sur une solution technologique alliant application mobile et plateforme en ligne : le projet Tiwouh.
Historiebrug
Authors: Poulsen Jens Aage
Published: April 2024

Jens Aage Poulsen præsenterer her et af de tre hovedfokusområder for de nye læringsmål i historiefaget, nemlig Historiebrug.

En af de mest iøjnefaldende ændringer ved de forenklede fælles mål for historieundervisningen i Folkeskolen er, at historiebrug nu er blevet et selvstændigt kompetenceområde. På den ene side kan historiebrug være et vanskeligt område at arbejde med både for lærer og elev. På den anden side må man sige, at netop forståelse af at ’historie’ er noget, som både kan bruges og misbruges, er helt centralt for børn og unge, der skal blive klogere af, og på, fortiden.
Hvad pokker er historiske scenarier?

Under kompetenceområdet Historiebrug i forenklede Fælles Mål findes arbejdsområdet Historiske scenarier. Det har formentligt fået en del undervisere til at overveje, hvilken undervisningsmæssig praksis dette arbejdsområde dækker over. Denne artikel vil give enkelte bud på historiske scenarier – bl.a. ved at påpege, at disse ikke er noget revolutionerende nyt.

Lad dine elever skabe historie
Authors: Petersen Nikolaj
Published: April 2024

Historiebevidsthed er et kernebegreb i historiefaget anno 2015, men er ofte meget svært at håndtere i en undervisningssituation. Det kan ofte blive meget abstrakt, når man forsøger at give sine elever en forståelse af, at de selv og alle andre mennesker både er historieskabte og medskabere af historie.

I denne artikel giver forfatteren et bud på begreber og redskaber, der kan gøre arbejdet med historiebevidsthed lettere at gå til, og peger på et nyt digitalt læremiddel, der baserer sig på netop denne tænkning, nemlig Den Sønderjyske Historiekanon.

Konspirationsteorier i historieundervisningen, sådan!
Authors: Peters Rikke Alberg
Published: April 2024

Konspirationsteorier er et spændende emne at tage op i historieundervisningen i de ældste klasser, men der mangler gode undervisningsmaterialer, og mange lærere føler sig på bar bund, når eleverne slippes fri i projektarbejdet.

Artiklen giver nogle konkrete redskaber til, hvordan læreren kan gribe emnet an i de ældste klasser og på ungdomsuddannelserne. Desuden beskrives hvilke elementer, eleverne bør arbejde med, hvis de skal nå til en mere problemorienteret forståelse af fænomenet konspirationsteorier.
Museer og skoler finder nye veje sammen
Authors: Byriel-Thygesen Mette
Published: April 2024

Med en længere skoledag og en skolereform, der vægter ’den åbne skole’, er der behov for at finde nye veje for samarbejdet mellem skoler og museer. Projektet 'Nye Veje' har haft til formål at gøre det lettere for lærerne at bruge museerne på egen hånd eller på nye måder sammen med deres elever.

På museerne kender vi alle skoler, der kommer med ”fakta-ark” på egen hånd, hvor det gælder om at finde årstal eller tip en 13’er. Nye Veje projektet er et forsøg på at opkvalificere skolernes museumsbesøg på egen hånd ved at inspirere til at bruge museerne i undervisningsøjemed på nye måder og i nye fag. Denne artikel er en afsluttende opsamling på erfaringer fra projektet.
Redaktionelt forord
Authors: Knudsen Heidi Eskelund , Peters Rikke Alberg
Published: April 2024

Som mennesker har vi altid brugt historie – både bevidst og ikke-bevidst. Vi bruger historie for at skabe mening og sammenhæng i vores liv, og vi bruger historie for at styrke vores argumenter til at fremme en bestemt sag. Fra den mundtlige overlevering hvor skjalde digtede om forfædres store bedrifter til vores ugentlige søndagshygge, hvor vi samles til et nyt afsnit af ’Historien om Danmark’, og fra politiske valgtaler til etiketter på marmeladeglas og smørindpakninger – således har historie altid været, vil fortsat være og vil blive anvendt i vores menneskelige fællesskab. Som sådan er det at forholde sig til det fortidige et menneskeligt eksistensvilkår, som vi ikke kan slippe uden om eller se os fri af.

Med dette RADAR-temanummer ønsker vi at sætte fokus på historiebrug som et centralt begreb i historieundervisningen og ikke mindst som et fænomen, der gennem de seneste år har fyldt meget i de faglige diskussioner blandt historielærere i grundskole og på ungdomsuddannelser såvel som blandt historiedidaktikere på universiteter og læreruddannelser.
Nærområdet i historieundervisningen – hvorfor og hvordan?
Authors: Poulsen Jens Aage
Published: April 2024

Fortiden, eller hvad der kan kaldes levet historie, er der ikke længere. Men også på skolen og i dens nærområde har den efterladt sig spor, som er oplagt at bruge i historieundervisningen. At arbejde med disse spor kan give eleverne forståelse for og erfaringer med, at historie er et undersøgende fag, hvor de selv skaber historie. Artiklen begrunder, hvorfor det er tilfældet, og den giver forslag til, hvordan man kan arbejde med nærområdet i historieundervisningen.

Et traditionelt vidensorienteret historiedidaktisk fagsyn har længe været - og er stadig i nogen grad - det dominerende og mest udbredte. Men faget historie, historieundervisning og læring, er andet og mere end et fortidsstudium med kanoniserede vidensområder. I artiklen udfoldes et mere kompetenceorienteret alternativ, som skal aktivere og motivere eleverne med henblik på at styrke og kvalificere deres historiske kompetencer.

Developing theory in motivational interviewing: academic and practitioner perspectives from MICBT integration
Authors:   , Earnshaw Paul G
Published: April 2024

Motivational Interviewing (MI) and Cognitive Behaviour Therapy (CBT) are both evidence based psychosocial interventions. Motivational interviewing has not sought to develop its own comprehensive theory (Miller & Rollnick, 2012) although it has developed hypotheses on why MI works. This project has looks at what an integration of these two approaches can tell us about motivational interviewing’s theory, hypothesised mechanisms of action and efficacy. It has set out to examine and explore existing theory through qualitative research. This included Semi structured interviews with researchers and practitioners who are experts in the integration of MI and CBT (MICBT). Their views and existing literature were used develop understanding about MI efficacy. A critical realist philosophical framework and Theoretical Thematic analysis was used to explore and test MI theory. A number of themes around hypothesised mechanisms and MI theory emerged from both sets of participants. These included psychological safety, alliance, responding to resistance, acceptance, compassion and positive emotion. A relational rather than a technical practice was emphasised and the theory relating to that observed. Theory around Power, its negative and positive operation in people’s lives arose frequently; as did hypothesised mechanisms relating to power differentials and MI as a ‘power yielding’ approach. Building on insights from evolutionary theory, links were made to a more detailed consideration of the effects of social context on research, practice and the ability of individuals to make change. This project challenges a narrow-individualised approach to research and intervention, emphasising the need to take into account the effects of social inequality and individual social circumstances. The project has illustrated some of the reality of translating theory into real-world practice and suggests expanding MI theory so that it is more contextualised. The centrality of understanding power and power structures may be a useful addition to an understanding of why MI works. An increased awareness of social context and its impacts raise questions about how individual and societal level interventions could work together to improve health behaviour change. Finally, a number of suggestions for future research are made, including that individualised interventions need to be evaluated in real-world services, with direct consultation of and involvement of service users.
Modern slavery in the UK: the role and impact of multi-agency collaboration
Authors:   , Brewster Benjamin
Published: April 2024

This thesis presents findings from research into the role and impact of five place-based multi-agency anti-slavery partnerships in the UK. The research uses a single case-study approach with multiple embedded units of analysis. It draws upon data from five geographic regions of the UK as the basis of a comparative analysis that involves the full spectrum of statutory and non-statutory organisations that undertake anti-slavery work. The thesis focuses, in particular, on the role of partnerships in victim identification and support, while simultaneously discussing issues and drawing upon existing discourse associated with policy, legislation and the macro conditions that impose barriers on such efforts. The research finds a developing landscape of anti-slavery partnership work, progressed, primarily, by statutory organisations such as the police and local government in each of the five regions. It identifies that within those regions, a range of activities are being undertaken that aim to support law enforcement, improve detection rates of victims, and work around limitations in national victim support provisions by raising awareness, providing training to public-facing staff and implementing local processes and practice. Overall, it concludes that although there is much to applaud in the range and scope of activity being undertaken by local partnerships, more work is needed across the board to evaluate their impact moving forward.
Understanding Experiences of High Achieving Sixth-form Students Through the Oxbridge Application Process
Authors:   , WIndle Damian
Published: April 2024

This thesis seeks to understand the experiences and decision-making processes of a distinct sixth form student cohort of high achievers based in a sixth form college in the North West of England. These students are identified as having gained seven grade 7s at GCSE upon entry to the college and are therefore placed on a separate pastoral programme known for the purposes of this study as the STAR cohort. Being a pastoral manager of the STAR cohort, I have witnessed the students hopes and disappointments in applying to elite universities and was conscious that studies of such groups remained an under-researched and under-theorised area of study (Mendick and Francis 2012). Therefore, this thesis seeks to understand this lived experience of being a high achieving student, shining a light on their preparation and decision making in applying to Oxford and Cambridge universi6es and also documenting and explaining how their understanding is informed. Undertaking research during the Covid-19 pandemic and utilising ethnographic techniques of interviews and focus groups informed by Bourdieusian field theory, this thesis finds the experience of these students to be one of pressure with a systema6c and relentless focus on grades. In addition, the student experience of applying to elite universities was often an obscuration: lacking transparency and clarity at each stage of the process and more akin to an arbitrary game of chance than a fair process. The STAR cohort felt that they bore full responsibility for any failure during the application process, resulting in low confidence and a sense of being a hesitant underdog. Moreover, the research suggests that the move to online interviewing and online Widening Participation programmes by Oxbridge post-lockdown only intensified this obscuration of the application process. Therefore, this thesis will contribute a fresh understanding in explaining the experience of being a high achieving sixth form student and will also address potential issues in the application process for how students in England apply to Oxford and Cambridge Universities. Thus, this study will be of use to teachers and educators in the post-16 sector and stakeholders and admissions tutors involved in the Oxbridge application process.
Experiência dos professores universitários durante a Pandemia da Covid-19
Authors: Leite Ana Luiza , Ferreira Roni Costa
Published: April 2024

A vida dos professores universitários foi significativamente impactada pela pandemia da Covid-19, o que resultou em alteração da satisfação e estresse desses profissionais. O objetivo desta pesquisa foi analisar a produção científica, por meio de uma revisão sistemática, sobre o impacto da pandemia no bem-estar do professor universitário. Após a busca por artigos em bases de dados, critérios de exclusão foram aplicados e restaram 42 artigos científicos para análise. A maioria dos artigos científicos está escrito em inglês e advém dos Estados Unidos, assim como, possuem abordagem quantitativa. Os resultados demonstraram que houve mais, em número e intensidade, desafios e dificuldades observados do que benefícios e oportunidades. No que tange aos benefícios, novas oportunidades de colaboração em pesquisa, mais atenção à saúde, e desenvolvimento profissional do docente. A rede de apoio profissional e familiar foi citada como um benefício durante a pandemia, e quando não percebida, como uma dificuldade. No que tange aos desafios, professores precisaram reformular suas aulas, metodologias de ensino, adaptar-se às tecnologias e engajar os alunos, o que aumentou a carga de trabalho significativamente. Por fim, apresentam-se informações necessárias para que Instituições de Ensino Superior possam desenvolver políticas que ajudem os professores a enfrentarem esses desafios, em busca da manutenção ou melhoria da qualidade do ensino superior.
Menga Lüdke e a pesquisa na formação de professores
Authors: Romanowski Joana Paulin , Fontana Maria Iolanda
Published: April 2024

A questão que orienta o estudo apresentado considera as contribuições de pesquisadoras brasileiras no campo da formação de professores para uma possível composição da teoria nesse campo.  O artigo focaliza as pesquisas e proposições de Menga Lüdke, precursora na defesa da prática de pesquisa no processo de formação docente para o desenvolvimento e profissionalização dos professores da educação básica. A metodologia do estudo, de abordagem qualitativa, recorre à perspectiva da história de vida, considerando dados biográficos e produção acadêmica de Lüdke, em que o currículo Lattes constituiu o ponto de partida e foi complementado por entrevista. As reflexões realizadas indicam o intenso envolvimento de Lüdke com a produção de referenciais relativos à socialização docente, valorizando a pesquisa realizada por professores da educação básica sobre suas práticas. A abrangência dos estudos de Lüdke sobre o professor e a pesquisa, no campo da formação de professores, ressaltam as investigações a respeito do cotidiano das escolas e o entendimento de que os professores contribuem para a compreensão da realidade concreta da prática pedagógica. A pesquisa, incorporada ao processo de formação e do trabalho do professor, eleva o estatuto de sua profissionalidade, ao assumir papel ativo frente aos problemas da educação.

O objetivo deste artigo é apresentar a trajetória profissional e a produção teórica de Madalena Freire. Realiza-se uma revisão bibliográfica para discutir as principais contribuições de seu pensamento pedagógico com base em quatro obras: A paixão de conhecer o mundo (1983; 1988); Observação, registro, reflexão – Instrumentos metodológicos I (1996); Avaliação e Planejamento: a prática educativa em questão. Instrumentos metodológicos II (1997); e, Educador, educa a dor (2017). A partir dessa revisão, articulada ao testemunho pedagógico das autoras, são discutidas e afirmadas as seguintes ideias-força: o compromisso com a docência e o ensino como atos políticos e pedagógicos; a escola como lugar de exercício da democracia e do trabalho em grupo; a pedagogia democrática, construída por meio da escuta, do cuidado e da aposta na capacidade das crianças de conhecer o mundo e construir conhecimentos mediados pela leitura e escrita; a disciplina intelectual mediante o estudo e o registro. O testemunho-pedagógico é o da paixão de conhecer o mundo pela paixão de ensinar e aprender com o outro na imprevisibilidade e irrepetibilidade de cada ato educativo.

The species was brought to Europe in the middle of the 19th century for the purposes of growing in gardens, but it spread very quickly and today it is one of the most invasive species in many European countries. It forms dense monodominant stands that crowd out native vegetation, posing a serious threat to biodiversity. In the researched area, the species R. japonica was recorded in 103 localities, and the largest number was found in the local communities of Obilićevo, Centar and Bulevar. Smaller stands with an area of up to 10 m2 are mostly represented. So far, the data on the distribution of this species in the area of the city of Banja Luka are scarce, so the goal of this work was to record the localities where the species R. japonica grows, so that its populations could be monitored in the future.

The known range of the species Dina sketi Grosser i Pešić, 2014 (Hirudinea: Erpobdellidae) includes several springs in the Cvrcka and Crna Rijeka basins (Republic of Srpska, Bosnia and Herzegovina). The biology of these leeches is insufficiently known. The aim of this paper was to present new knowledge about their ecology and reproductive biology, based on data collected in the springs of the Crna Rijeka basin. The analyzed parameters included characteristics of the biotope and macrozoobenthos assemblages of the studied springs, as well as characteristics of diet and the cocoons of D. sketi. The features of the biotope partially fit into the known range for this species. D. sketi is the only species of leech found in macrozoobenthos of the study area, where it is represented by less than 1%. The amphipod crustaceans and hydrobid gastropods are the most abundant members of the analyzed macrozoobenthos assemblages. The analysis of contents of the digestive tract revealed that these leeches prey on aquatic and terrestrial invertebrates. It seems that leeches prefer amphipods in their diet. All previous knowledge about the reproductive biology of D. sketi was based on description of their reproductive system. This paper presents the morphology and morphometric properties of the cocoons. They are “kiwi-shaped”, 4.60–8.82 mm in length and 3.19–6.38 mm width.

Published: April 2024

The first, after a long absence of any scientific research, faunal findings from the area of the Volujak Mountain (southeast of the Republic of Srpska, Bosnia and Herzegovina) were presented. In addition to listing the diversity of mammal fauna, data on other faunistic groups (birds, reptiles, amphibians, fish and invertebrates) were also recorded. Various methods were used to detect the presence of the fauna of the research area: established transects, trapping with livetraps, netting for catching bats, recording organisms with an ultrasonic detector, photo-traps and visual observation. For 17 days of research, in July and August 2023, a total of 53 taxa were registered. Keystone and endangered species are distinguished: greater horseshoe bat (Rhinolophus ferrumequinum), lesser horseshoe bat (Rhinolophus hipposideros), gray wolf (Canis lupus), brown bear (Ursus arctos), Balkan chamois (Rupicapra r. balcanicus), meadow viper (Vipera ursinii macrops) and the beech longhorn beetle (Morimus funereus). The area is very important in terms of biodiversity, and it needs to be protected.

Diverzitet slatkovodne ihtiofaune Bosne i Hercegovine (BiH) broji oko 117 (pod)vrsta riba i čini oko 20% evropske slatkovodne ihtiofaune. Sliv rijeke Vrbanje nalazi se u središnjem dijelu BiH i jedan je od autohtonih slivova u Republici Srpskoj. Rijeka Vrbanja jedna je od najvećih desnih pritoka rijeke Vrbas, pri čemu dužina donjeg dijela toka iznosi oko 28 km. Ihtiološka istraživanja donjeg dijela toka rijeke Vrbanje provedena su tokom 2013. godine na tri lokaliteta, a uzorkovanje je vršeno elektroagregatom za lov ribe ELT 62 II GI, 3 kW. Konstatovan je kvalitativno-kvantitativni sastav ihtiofaune kao i određeni indeksi diverziteta (Simpsonov indeks, Šenon-Viverov indeks, indeks dominantnosti i Sørensenov indeks sličnosti). Ustanovljeno je da donji dio toka rijeke Vrbanje naseljava 10 vrsta riba iz tri familije (Cyprinidae, Cobitidae i Percidae), pri čemu je familija Cyprinidae pokazivala najveće bogatstvo vrsta. Vrste koje su dominirale kako sa brojem jedinki, tako i biomasom bile su Barbus balcanicus i Squalius cephalus, što se umnogome razlikuje od ihtiofaune koja je naseljavala isto područje sredinom 20. vijeka. Ovakav sastav ihtiofaune donjeg dijela toka rijeke Vrbanje dovodi se u vezu kako sa faktorima životne sredine tako i sa uticajem određenih antropogenih aktivnosti.

Ambrosia artemisifolia (ambrozija), kao izuzetno invazivna vrsta koja brzo nalazi optimalne uslove za rast, nije samo jak alergen već može značajno da ugrozi kvalitet biljne zajednice. Alelopatski uticaj između ambrozije i drugih vrsta biljaka još uvijek nije dovoljno razjašnjen, što otežava razumijevanje komatibilnosti sa drugim biljkama, kako u poljoprivrednim, tako i u prirodnim uslovima. U ovom radu pratio se alelopatski uticaj vodenog ekstrakta izolovanog iz suvih listova ambrozije (10, 5, 2,5 i 1,25%) na klijavost sjemena, te rast kukuruza i pšenice. Vodeni ekstrakti ambrozije smanjili su klijavost kukuruza i pšenice i do 70%. Dužina klijanaca također je bila inhibirana, posebno pri višim koncentracijama. Pšenica se pokazala kao tolerantnija na djelovanje ekstrakata. Veći inhibitorni uticaj na dužinu korijena i izdanka utvrđen je kod kukuruza, pa se može reći da je ova vrsta osjetljivija. Dobijeni rezultati pokazali su da je potrebno pravovremeno suzbijati ovu korovsku vrstu kako bi se izbjeglo njeno inhibitorno dejstvo u usjevima gajenih biljaka.
ALLELOPATHIC EFFECTS OF RAGWEED ON CORN (Zea mays L.) AND WHEAT (Triticum aestivum L.)

Ambrosia artemisifolia (ragweed) is an invasive plant species with severe allergenic effects which quickly detects favorable growth conditions and represents a threat to the quality of plant communities. There are still unanswered questions to the allelopathic effects of ragweed on other species, which further complicates the understanding of its compatibility with other plants in both natural and agricultural environment. The paper monitors the allelopathic effects of the aqueous extract isolated from dry ragweed leaves (10, 5, 2.5 and 1.25%) on the germination and growth of corn and wheat. The aquaeous ragweed extracts reduced the germination of corn and wheat down to 70%. The seedling length was inhibited, especially in high concentrations. Wheat appeared to be more tolerant to the extract effect. Corn suffered a larger inhibition effect in terms of root length and seedlings, which suggested that this species was more sensitive. The obtained results imply that the ragweed should be combated in a timely manner in order to avoid its inhibitory effects on the indicator crops.

Published: April 2024

The target location of the Banja Luka-Prijedor motorway alignment is situated in the western Republic of Srpska and belongs to the northern axis of development, which is the belt of the most intensive economic and social activity. Before starting the construction, it is necessary to determine the state of surface water pollution, that is to say the zero state, in order to later have a pragmatic idea of the impact of traffic on the quality of surface water during the motorway operation. The paper presents the results of surface water analysis, which will be the basis for further assessment of possible changes in quality when the highway is put into operation. In order to provide a detailed analysis of the existing surface water quality in the investigated corridor of the future motorway, the physical-chemical parameters of the Kozaračka River and the Luščica River were analyzed. The obtained results show that the water quality of these watercourses in relation to certain parameters ranges from the first to the fourth class of water quality.

Unexplored soil bacteria isolated from Muna Island, Southeast Sulawesi, Indonesia, provide a new source of active molecules serving as prospective antibacterial agents. In the present research, the antibacterial and antibiofilm activities of bacterial isolates obtained from Muna Island were evaluated. Based on the preliminary screening through the antagonism assay, 5 out of the 15 isolates exhibited various spectra of antibacterial activities. At a concentration of 80 mg/ml, metabolites extracted from the two selected isolates, M7 and P1 inhibited the growth of the five multidrug-resistant strains. These extracts exhibited minimum inhibitory concentration and minimum bactericidal concentration values of 312.5 μg/ml to more than 10,000 μg/ml. An analysis of the 16S rRNA sequences revealed that the corresponding isolates were closely related to Bacillus aerius strain 24K and Priestia (Bacillus) aryabhattai strain B8W22, with >97% similarity. Some genes involved in antibiotic biosynthesis, such as mlnA, baeR, srfA, dfnD, and bacD, were also present in the bacterial genome. Liquid chromatography-tandem mass spectrometry analysis of the most potent M7 extract showed that it contained several antibacterial compounds, such as cyclo(D-Pro-L-Tyr), marinoquinoline G, and rancinamycin Ib.

Antimicrobial resistance (AMR) is identified as the fourth leading cause of mortality in Jordan. However, there is a scarcity of data addressing the demographics and clinical characteristics associated with AMR against commonly used antibiotics in Western Jordan. To address this knowledge gap, a retrospective analysis was undertaken on the microbiology records of AMR at Al-Hussein/Salt Hospital in Jordan West from October 2020 to December 2022 and included 2893 reports. Two machine learning (ML) models, specifically categorization regression trees (CARTs) and random forests (RFs) were trained using microbiology reports and then utilized to forecast the AMR for different categories of antibiotics. The most commonly isolated microorganisms were Escherichia coli (53.3%), Klebsiella pneumoniae, and Staphylococcus aureus. Bacterial strains belonging to the Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species category demonstrated elevated levels of resistance. The RF model demonstrated superior accuracy compared to the CART, exhibiting a range of 0.64–0.99. This finding suggests a significant level of dependability in the predictive capability of the RF models in forecasting AMR patterns. AMR is susceptible to the impact of demographic factors such as age, sex, and bacterial species. This study emphasized the significance of monitoring AMR to facilitate the administration of appropriate antibiotic therapy.

In the Firmicutes phylum, GpsB is a membrane associated protein that coordinates peptidoglycan synthesis with cell growth and division. Although GpsB has been studied in several bacteria, the structure, function, and interactome of Staphylococcus aureus GpsB is largely uncharacterized. To address this knowledge gap, we solved the crystal structure of the N-terminal domain of S. aureus GpsB, which adopts an atypical, asymmetric dimer, and demonstrates major conformational flexibility that can be mapped to a hinge region formed by a three-residue insertion exclusive to Staphylococci. When this three-residue insertion is excised, its thermal stability increases, and the mutant no longer produces a previously reported lethal phenotype when overexpressed in Bacillus subtilis. In S. aureus, we show that these hinge mutants are less functional and speculate that the conformational flexibility imparted by the hinge region may serve as a dynamic switch to fine-tune the function of the GpsB complex and/or to promote interaction with its various partners. Furthermore, we provide the first biochemical, biophysical, and crystallographic evidence that the N-terminal domain of GpsB binds not only PBP4, but also FtsZ, through a conserved recognition motif located on their C-termini, thus coupling peptidoglycan synthesis to cell division. Taken together, the unique structure of S. aureus GpsB and its direct interaction with FtsZ/PBP4 provide deeper insight into the central role of GpsB in S. aureus cell division.
