Fluxo de potência intervalar para sistemas de distribuição multifásicos baseado no método da injeção de correntes trifásico
Authors:   , Rodrigues Junior Heitor Magno
Published: December 2024

A incorporação de incertezas no problema do fluxo de potência em sistemas de média tensão representa um desafio contemporâneo devido ao advento de tecnologias que possibilitam a inserção de novos tipos de cargas e fontes renováveis com alta variabilidade, por exemplo. Diante desse complexo cenário, é urgente o desenvolvimento de métodos que representem as redes de distribuição com todas as suas peculiaridades como topologia predominantemente radial, existência de impedâncias mútuas, condutores de fases desequilibradas, representação do neutro e impedâncias de aterramento. Devido à escassez de estudos que abordam incertezas em redes com tamanha complexidade, esta tese almeja propor abordagens que solucionem essa problemática. Este trabalho apresenta um acervo metodológico baseado no fluxo de potência intervalar (FPI) usando as equações do método de injeção de correntes assumindo incertezas relacionadas aos valores de carga e geração. Na primeira abordagem proposta, é desenvolvido um fluxo de potência intervalar para análise da inserção de unidades de geração distribuída (GD) em redes ativas com representação monofásica. Nesse contexto, o impacto das unidades de GD nos resultados de magnitudes e ângulos de tensões intervalares é avaliado através do índice denominado sensibilidade intervalar percentual. Nessa ocasião, o sistema ativo IEEE 18-barras é utilizado para a condução de simulações computacionais. A segunda metodologia desenvolvida apresenta o Método de Injeção de Correntes Trifásico Intervalar (MICTI), uma nova abordagem que consiste no cálculo do FPI aplicado ao Método de Injeção de Correntes Trifásico (MICT) para sistemas a três fios e também envolvendo o condutor neutro. A principal contribuição desta tese se baseia no uso de extensões intervalares e na aplicação da técnica de rotação angular. A execução dessas estratégias de aprimoramento das soluções intervalares tornaram os cálculos mais assertivos e reduziram a superestimação dos resultados, problema enfrentado quando ocorre a simples aplicação da aritmética intervalar convencional no cálculo do fluxo de potência trifásico. As metodologias tratadas na tese são pioneiras, de modo que antes dos trabalhos publicados oriundos dessa pesquisa, não havia na literatura nenhuma referência que tratava do desenvolvimento de métodos de FPI baseados na aritmética intervalar tradicional através das equações de injeção de correntes em sistemas multifásicos e multiaterrados. Os resultados obtidos fornecem soluções de esforço computacional relativamente baixo, confiáveis e compatíveis com as simulações de Monte Carlo. Além disso, todas as metodologias propostas representam um recurso viável para calcular o impacto de dados de entrada incertos nos resultados intervalares do fluxo de potência compreendendo as tensões trifásicas e as de neutro, também conhecidas como Neutral-to-Earth Voltages.
Eu sou o que vejo - representação e representatividade negra na literatura infantil contemporânea
Authors:   , Pestana Cristiane Veloso de Araujo
Published: December 2024

A presente tese, de cunho interdisciplinar, abrange as áreas de Letras, Educação e Artes e tem como objetivo central analisar as imagens dos livros de Literatura Infantil com temática étnico-racial, com foco naqueles que trazem personagens protagonistas negras. Serão cerca de dez livros infantis analisados, além dos que tiveram apenas uma ou outra imagem mencionada, em sua maioria publicados na última década. As análises serão bibliográficas e levam em conta o aumento significativo dessas publicações após a implementação da lei 10.639/03 e a falta de uma crítica literária consolidada em torno das obras, sobretudo no tocante às ilustrações. No entanto, também conta com experiências vividas pela pesquisadora no espaço escolar e observações feitas a partir do contato de seus alunos com os livros. Compreendendo que as imagens chegam mais rapidamente às crianças, principalmente aquelas ainda não alfabetizadas, levanta-se a hipótese de que o livro com ilustração assume o caráter de livro ilustrado, pois a criança que ainda não domina a leitura das palavras vai ler e compreender a narrativa através do texto visual. Sob este aspecto conclui-se que as imagens antirracistas promovem uma interação positiva capaz de desenvolver na criança negra uma identificação afetuosa, a qual dá-se o nome de Representatividade. Durante a pesquisa, discutiremos ainda o racismo presente na escola e nas representações literárias; o embranquecimento das personagens como vertente do racismo e, finalmente, apresentaremos exemplos de livros que trazem em suas ilustrações imagens positivas e realmente representativas para nossas crianças. Para fundamentar nossas discussões teóricas utilizamos os conhecimentos partilhados por autoras(es) como Nilma Lino Gomes (racismo e educação), Kabengele Munanga (racismo e mestiçagem), Eliane Cavalleiro (racismo e escola), Maria Anória de Jesus Oliveira (literatura infantil e juvenil), Eliane Debus (literatura infantil e juvenil), Lia Schucman (branquitude), Alessandra Devulsky (colorismo), entre outros. Sobre as imagens e ilustrações utilizamos prioritariamente os estudos de Joly Martine, Lúcia Santaella, Graça Ramos, Sophie Van der Linden, Nikolajeva e Scott.
O projeto político do povo negro para o Brasil: narrativas políticas e identitárias de uma nação “igualmente imaginada”
Authors:   , Gonçalves Ana Cláudia
Published: December 2024

O contexto da refundação da democracia brasileira traz, dentre suas principais inovações, a inserção dos negros na estruturação do projeto nacional. À vista disto, nesta tese, analiso como a questão racial passou a ser incorporada à construção da nação. Para tanto, examino este debate tanto por meio da documentação escrita por intelectuais e ativistas negros quanto por meio de registros governamentais. Deste modo, trata-se de uma pesquisa que investiga não apenas o quadro da redemocratização e da Assembleia Nacional Constituinte, mas também o processo da elaboração de novos imaginários, os quais compõem e ressignificam a nação na contemporaneidade.
A coconstrução de interações caracterizadas por atos de violência física: uma análise linguístico-interacional dos elementos multimodais de provas em vídeo da Justiça Militar
Authors:   , Augusto André Lázaro Ferreira
Published: December 2024

Este trabalho analisa três casos com evidências em registro audiovisual que tramitaram na Justiça Militar da União. Filmagens podem integrar autos judiciais e servir como provas para a formação do convencimento do juiz, tendo especial relevância em processos criminais caracterizados pela prática de atos de violência física. A interpretação dessas imagens não é óbvia, gerando dúvidas ao expectador sobre a natureza da atividade desenvolvida. Essa dificuldade, aliada à ausência de treinamento, conduz à deficiência da interpretação da prova em vídeo nos Tribunais (SILBEY, 2008; KAHAN, 2009; SHERWIN, 2011; RICCIO; GUEDES, 2022; RICCIO; MESSIAS; GUEDES; MATTOS, 2019; AUGUSTO; RICCIO; VIEIRA, 2021; AUGUSTO; VIEIRA; RICCIO, 2023). Assim, o objetivo desta pesquisa exploratória (GIL, 2002) é investigar como ocorre a coconstrução de uma interação registrada em prova em vídeo e caracterizada por atos de violência física. Para compreender como os elementos da atividade evidenciam o enquadre de violência física, se é observada ambiguidade nas interações e como ela se estrutura e como as ações dos participantes circunstantes contribuem para a configuração dessa atividade, adotou-se a análise da Sociolinguística Interacional (BATESON, 2013; GOFFMAN, 1986, 2013; GUMPERZ, 2013; KENDON, 1990; ROSSANO, 2013; GLENN, 2013) aliada a pressupostos da multimodalidade (STIVERS, 2013; CRUZ; OSTERMANN; ANDRADE; FREZZA, 2019). A metodologia é qualitativa e interpretativa (DENZIN; LINCON, 2006), adotando-se o método do estudo de caso múltiplo (YIN, 2015). Os dados foram transcritos conforme os Modelos Jefferson (LODER, 2008) e Mondada (2022). Os resultados indicam que os elementos multimodais extraídos permitem compreender diversos aspectos da atividade, como a natureza do enquadre, o alinhamento dos interagentes, os momentos e atitudes que antecedem as agressões e as estratégias para a redução da intensidade ou mesmo para a cessão dos atos de violência física. A pesquisa, portanto, consiste na aplicação prática de teorias combinadas de Goffman (1986) e Gumperz (2013) voltadas à interpretação de um enquadre complexo e desafiador, podendo as inferências obtidas auxiliar profissionais da Linguística Forense e, consequentemente, do Direito.
Ferramenta computacional para planejamento cirúrgico tridimensional otimizado da osteotomia periacetabular de Ganz via algoritmos genéticos e método dos elementos finitos
Authors:   , Ferraz Marcus Vinicius de Souza
Published: December 2024

A displasia do desenvolvimento do quadril (DDQ) é uma patologia que se caracteriza pela relação anormal entre cabeça femoral e acetábulo. A osteotomia periacetabular (OPA) é uma cirurgia preservadora do quadril, que visa aumentar a cobertura acetabular da cabeça femoral, minimizando as pressões de contato, por meio do reposicionamento da articulação coxofemoral. Nesse contexto, a presente tese busca desenvolver uma ferramenta computacional que foi testada para aplicação em pacientes com deformidades articulares nos quadris. Esses casos foram essenciais para testar e avaliar a ferramenta desenvolvida, visando implementar uma aplicação clínica-cirúrgica de método de planejamento cirúrgico tridimensional otimizado por parâmetros biomecânicos, como pressão de contato, área de contato e força de contato. O objetivo é avaliar a segurança, acurácia e reprodutibilidade da metodologia proposta. O planejamento é obtido a partir do processamento digital de imagens de tomografias computadorizadas de pacientes diagnosticados com deformidade nos quadris e indicação de osteotomias acetabulares e/ou femorais, por um cirurgião habilitado e com ampla experiência na técnica digital. A otimização do posicionamento das correções (utilizando-se duas estratégias distintas) é derivada da análise computadorizada das interações simuladas entre as superfícies articulares do quadril utilizando análise com elementos finitos via Abaqus® e seleção dos ângulos otimizados de reposicionamento do fragmento acetabular, com base em um algoritmo genético. A acurácia da correção obtida pelo planejamento otimizado é comparada com os modelos pré-operatórios e planejados virtualmente pelo cirurgião, e identificou-se que estes apresentaram melhor desempenho em relação ao modelo patológico em todos os estudos de caso. Os ajustes na correção, propostos pela técnica evolucionista (AG), foram validados através da análise dos parâmetros clínicoradiográficos em todos os estudos de casos testados, levando em consideração os limites de normalidade dos mesmos.

Authors: Dufour Blanche , Grandjean Dominique
Published: December 2024

Cette étude s’appuyant sur des sondages et des recherches bibliographiques a été réalisée dans le cadre d’une thèse pour l’obtention du doctorat vétérinaire. L’objectif est de résumer l’impact que la crise sanitaire du SARS-CoV-2 a eu sur le milieu vétérinaire français. En particulier, il a été mis en évidence que les outils et les compétences scientifiques des vétérinaires n’ont pas suffisamment été mis à profit durant la gestion de la crise sanitaire. Par exemple, les laboratoires départementaux vétérinaires, le dépistage olfactif canin et l’aide humaine proposée par les vétérinaires ont été très peu utilisés, et ne l’ont été que tardivement dans la chronologie de la crise sanitaire. À l’avenir, la gestion de la crise sanitaire liée au SARS-CoV-2 doit permettre de tirer pour le long terme, des enseignements sur le potentiel que représente la profession vétérinaire dans la gestion des épidémies et épizooties, à l’instar du concept « One Health ».

A REVIEW OF THE IDENTITY AND BIOSTRATIGRAPHY OF CENOMANIAN “LARGER” BENTHIC FORAMINIFERA: PART 1 – THE NEZZAZATOIDEA
Authors: Simmons Michael , Bidgood Michael , Consorti Lorenzo , Schlagintweit Felix
Published: December 2024

The Nezzazatoidea (“nezzazatoids” herein) is a superfamily of “larger” benthic foraminifera (LBF) that are common in the Cretaceous (especially mid-Cretaceous) neritic carbonate successions of Neotethys. They are encountered in suitable rocks in a broad belt centred around Central America, the Mediterranean region, the Middle East, and the Himalayas. To improve their stratigraphic utility, the identities and distribution of 15 species are critically reviewed based on published records, these taxa having at least possible occurrences in Cenomanian strata. It is shown that misidentifications have erroneously overextended the ranges of some taxa. However, there are indeed species that have long ranges, suggesting some nezzazatoids form part of a group of environmentally tolerant LBF that were able to recover from palaeoceanographic events such as widespread anoxia or sea-level change. Some of these taxa have short ranges within the Cenomanian that mark them out as potential species to be used, alongside species from other LBF groups, in the development of a biozonation/bioevent scheme for Cenomanian LBF. As with almost all mid-Cretaceous LBF, work on taxonomy/identity of nezzazatoids is an ongoing task requiring access to pristine material, including topotypes.

Published: December 2024

This research aims to explore strategies for improving Al-Quran Reading and Writing (Baca Tulis al-Quran / BTQ) skills in public schools, with a case study at SMAN 2 Bandung. Studying the Koran is essential for every Muslim that studying the Koran is the most important thing for every Muslim, especially in terms of reading each verse in it which contains certain tajwid laws that must be obeyed when reading it. However, in reality there are quite a few people who still make mistakes in reading and pronouncing the Koran. Reading and Writing the Qur'an is a key skill in Islamic education, focusing on both Arabic mastery and character development, but also contributes to the development of students' character and morals. Data was collected through semi-structured interviews, observations, and document studies, which were then analyzed using the Miles and Huberman model. The results of this research indicate that limited time and minimal support for learning at home are the main challenges in implementing BTQ in public schools. The school applies the "bandungan" method for BTQ learning, where students take turns reading with correction from teachers and classmates, as well as daily Koran assignments at home.

Published: December 2024

In the field of heritage language and culture studies, this article sets out to answer the following question: how does the Ukrainian Society of Brazil preserve, promote and publicise Ukrainian identity among its members and in the city of Curitiba (Brazil)? Through an exploratory and ethnographic documentary research, the researcher presents three pillars of the institution for analysis: the Barvínok Ukrainian Folklore, the Subotna Chkola Léssia Ukrainka and the „Ukrainian Memory Project through the historical collection of the Ukrainian Society of Brazil”. The focus of the analyses is on the aspect of adherence to Ukrainian cultural and national values and defence of the country on Brazilian territory, observed within the Ukrainian community of Curitiba. In the context of the activities of the Barvínok Ukrainian Folklore, there are actions aimed at the preservation and transmission of traditional dances and music; the knowledge of these cultural expressions on the part of the members; and the promotion of events that celebrate and valorise Ukrainian commemorative dates. Subotna Chkola provides children and teenagers with contact with this language and culture from an early age. The Memory Project encourages the care and safeguarding of documents which, in turn, build up the history being written by the Ukrainian community in Brazil.
“You believed that I was an abstract illusion...”. The Spectrality of Radu Stanca’s Erotic and Thanatic Chimeras
Authors:   Università degli Studi di Bari “Aldo Moro”, Dipartimento di Ricerca e Innovazione Umanistica, Magliocco Giovanni
Published: December 2024

This contribution will map the spectrality of some erotic
chimeras that magnetize Radu Stanca’s poetic and existential quest. Through the hermeneutics of some significant poems – such as Liliacul, Canossa, Ascuţitorul de cuţite, Lamentaţia poetului pentru iubita sa, Elegia, Baladă studenţească, Doti, etc. – the motif of the inaccessibility of the chimerical and spectral woman will be analyzed in depth. In some texts, we will also show that, at times, a reversal occurs between the feminine and the masculine polarities, as it is rather the masculinity that is configured by the poet as constantly inaccessible and chimerical – for example in Fata şi zmeul or in Pajul cu păr de aur. In many of Radu Stanca’s poems, Eros not only undergoes an idealization, but even a spectralization, since the chimeras that haunt these poems are not only inaccessible and evanescent as shadows, but even seem to turn into phantomatic visions. It is precisely this spectralization, pushed to its extreme consequences, that explains the profoundly thanatic character of Stanchian Eros.

A method to estimate pixel intensity in line scan camera-based measurement systems using exposure and lighting control signal characteristics
Authors: Forgács Zsófia
Published: December 2024

The operation of machine vision control systems is greatly influenced by the lighting technology used. If the camera exposure signal and the LED pulse train come from different sources, their start times may not align. While matching the frequency of the exposure signal and the lighting control signal can enable full synchronization by adjusting the phase shift, in practice, the camera’s sampling frequency and the lighting controller’s signal frequency may differ, potentially leading to resonance effects and intensity variations in the captured images. To investigate this phenomenon and develop a compensating algorithm for frequency discrepancies, a procedure was devised to estimate the intensity resulting from the overlap of the signal curves.
Investigating the impact of vibration characteristics on the surface roughness using MPU6050 sensor at turning of 11SMn30 steel
Authors: Tanuj Namboodri , Felhő Csaba
Published: December 2024

Manufacturing system automation is becoming more and more important in sectors due to the growing digital revolution (Industry 4.0) and economic competitiveness. One of the key criteria for making machines entirely automatic is the installation of sensors on the machine. Industrialists have used speed, temperature, and other sensors to offer real-time data and examine faults but sensors to interpret vibration are still being developed. One of the primary impacts of vibration is on the surface roughness. Surface roughness has an impact on several factors affecting the machine, including stress concentration, frictional wear, corrosivity, and so on. To prevent such failures, this study focused on identifying a correlation between vibration and surface roughness by adjusting the feed rate and it was found  92.2 % correlation is noted in between vibration and arithmetic average surface roughness.

A tanulmány célja az alacsony költségű, környezeti levegőben található részecskék (PM2.5) koncentrációjának mérésére fejlesztett érzékelő teljesítményének értékelése. Az érzékelő képes több meteorológiai paraméter, például hőmérséklet, relatív páratartalom, harmatpont, valamint légszennyező anyagok, mint az illékony szerves vegyületek (VOC) és a nitrogén-oxidok (NOx) egyidejű mérésére. Ezek az adatok kulcsfontosságú összefüggéseket tárnak fel a levegőminőségre ható környezeti tényezők jobb megértéséhez. Az érzékelőrendszer központi eleme egy Sensirion mérési modul, amely kompakt, energiatakarékos kialakításával valós idejű adatgyűjtést biztosít, helyhez kötött és mobil alkalmazásokhoz egyaránt. A tesztelés során az összeállított érzékelőegységet olyan bevált referenciarendszerekhez viszonyítottuk, mint a TSI DustTrak és a HungAIRy megfigyelőhálózat. Az eredmények erős korrelációt (R² >0,9) mutattak a Sensirion-alapú egység és a nagy pontosságú műszerek között, különböző környezeti feltételek és PM2.5 koncentrációs szintek esetén. Az érzékelő pontossága és megbízhatósága ígéretes eszközzé teszi a széles körű, alacsony költségű levegőminőség-monitorozás területén.

In our work, we have reviewed and examined the management practices of older technologies for the treatment of oily waters, oily sludges and emulsions in terms of their potential for improvement. We found that the technology used is not suitable for emulsion degradation. Based on a review of some of the technologies used in international and national practice, we have selected the emulsion degradation equipment that can be proposed for the treatment of emulsions and that can be optimally integrated into the older technology. The occupational safety and chemical risks of the selected vacuum evaporation technology were analysed and evaluated in comparison with the risks of the applied technology. It was concluded that the proposed development of the technology does not pose any additional occupational safety and health risks to workers.
Dinâmica do mercado de óleos essenciais para uso individual no Brasil: um olhar sob a perspectiva dos atores da cadeia produtiva

Published: December 2024

Recentemente, o uso individual de óleos essenciais para saúde e bem-estar popularizouse no Brasil. Com esse aumento de demanda, mais produtores e empresas entraram para o mercado de óleos essenciais para uso individual. Dessa forma, este trabalho buscou descrever a cadeia produtiva e a dinâmica desse mercado pela perspectiva de produtores, empresas, revendedores e especialistas. Para alcançar esses objetivos, foram realizadas entrevistas semiestruturadas, empregando análise de conteúdo, e discutindo-as com base na revisão de literatura. Os relatos obtidos evidenciam uma cadeia complexa e diversa, e um mercado em expansão, de um produto que vem sendo banalizado, colocando em risco a saúde dos consumidores. Há também a entrada de um perfil de consumidor leigo, que, em geral, dá preferência ao preço em detrimento da qualidade dos produtos. Além disso, a concorrência desleal existente é perigosa para a sustentabilidade do mercado.

Migration is linked to environmental issues through a variety of mechanisms. Economic, political, demographic and cultural factors are interconnected with climatic ones. All together, they form among the population a certain kind of migration response in the “leave or stay” coordinate system. The full-scale invasion of the Russian Federation into Ukraine has led to catastrophic consequences in both the migration and environmental spheres. The influence of the military factor at the moment is not final since the situation is constantly changing due to ongoing active battles. In the future, scientists will have to reveal and characterize the consequences of the full-scale war on the migration of the Ukrainian population, environmental changes and the interaction between these two domains. There are no doubts that these consequences are supranational in nature, going far beyond the borders of Ukraine. The study of materials from the pre-war period on the aforementioned problems gives an important base for subsequent developments. This article aims to investigate the relationship between migration and climate change in the migration legislation of Ukraine. In the process of work, methods of document analysis, generalization, comparison, induction and analogy were used. The research showed the insufficient representation of environmental factors in migration legislation. A small number of direct relationships between migration and environmental spheres were found. They were built in the legislation through the prism of social protection of certain categories of migrants. However, the existing legal field provides potential opportunities for expanding such interaction. The proclaimed principle of compatibility of migration policy with other spheres of state activity is surely open to the environmental sphere. Additionally, the state can use the resource potential of return migrants and refugees, stimulating energyefficient, environmentally friendly production and opening enterprises that contribute to solving environmental problems in Ukraine. However, such initiatives can be implemented on a large scale after restoring a peaceful way of life.

Authors: Negrea Claudiu Ioan , Scarlat Ela Madalina
Published: December 2024

This research paper addresses the need to achieve a higher financial inclusion and the challenges to a higher adoption of digital payments in Romania, while decreasing the use of cash, related to the physical infrastructure and regional disparities, financial intermediaries, consumer preference and financial education, by conducting a descriptive research, using quantitative and qualitative analysis of secondary data. The study highlights the current infrastructure, some relevant legislation implications and the population’s payment habits and perception. We presented some opportunities provided by European funding and digital technologies in increasing accessibility, consumer confidence and a higher adaptability of payment serices to meet consumers’ needs and expectations, addressing the developments made in Romania, the limitations of implementing a cash-less economy which would need to include the on-boarding of all disadvantaged groups as well, potential risks related to cyber-security and cyberresilience and possible public policy implications to eliminate gaps in digital literacy, the level of financial education, cybersecurity awareness and the need for public-private coordinated pro-inclusion measures. The conclusions of this research could be used by authorities, by the banking sector and by FinTech companies, to tackle reaching the optimal balance between public intervention and private initiative for increasing financial inclusion, taking the national context into account.
Alternative methods to measuring the Romanian economy’s business cycle
Authors: Radu Stefan-Constantin
Published: December 2024

The following paper we will present a series of mathematical models that have the scope of approximating the business cycle of the Romanian economy for the period between 1995 and 2022 by using quarterly data of the Gross Domestic Product. The main findings of the paper suggest the use of three different methods for approximating the business cycle, with very interesting and varied results. The accuracy of the approximation of the proposed methods is compared to the traditional method of using the Hodrick-Prescott filter. The originality of the paper lays in applying different methods of calculating the business cycle and comparing their effectiveness for the case of the Romanian economy. In this case we observe that when comparing the methods for the Romanian economy, the alternatives to the Hodrick-Prescott filter are viable and useful.
Digital financial technologies and green finance, support tools for the sustainable development of the economy
Authors: Manta Otilia
Published: December 2024

The current challenges at European and global level have involved the major risk of a severe recession affecting the entire EU economy, including Romania, with direct consequences for businesses, jobs and households, especially in the current pandemic context. As financial technologies shape the future of the financial world in ways most of us have never anticipated, finance experts will have to keep up. Moreover, in the context of the European Environment Agreement and the Global Environment Agreement, funding will face a new challenge posed by the introduction of green funding, which we can say will be found in all areas of activity, including insurance. The European financial market is constantly adapting to current challenges, making it not only more competitive but also an innovative European financial market. In this paper, we intend to develop a plan of proposals for measures and solutions to support the national economy through financial instruments "green bonds", including the proposal of financing mechanisms and models for innovative financial instruments in the context of crises generated by current challenges.
Exemple de bune practici vizând reducerea discriminării pe piața muncii a persoanelor cu dizabilități
Authors: Nita Dorina
Published: December 2024

When we talk about discrimination, regardless of whether it is done in the context of the labor market or otherwise, it is considered a form of marginalization, the application of a differential, prejudicial treatment, receiving a negative connotation. Currently, numerous European legislative acts are dedicated to combating discrimination, being mainly focused on preventing discrimination based on nationality and sex, but not excluding race, ethnic origin, religion or religious beliefs, disability, age or sexual orientation. Starting from the European legislation in force, based on the statistical data provided by Eurostat, reports and case studies that focus on the issue of people with disabilities, this paper aims to reveal a brief picture of the current situation faced by people with disabilities on the labor market, as well as initiatives that can constitute good practice models related to the insertion and retention of these people on the labor market.
Study of the effectiveness of using a selective cephalexin component in a CCA nutrient medium for the detection of clinical isolates of Bordetella bronchiseptica
Authors: Gadzevich D. V.
Published: December 2024

Bordetellosis is a highly contagious infectious disease of farm and small domestic animals caused by bacteria of the species Bordetella bronchiseptica (B. bronchiseptica). According to the scientific literature and the results of our previous studies, the bacteriological method of laboratory diagnosis of bordetellosis remains the main diagnostic tool. Our preliminary studies show that the efficiency of bacteriological studies and isolation of clinical isolates of B. bronchiseptica from nasopharyngeal secretions is increased when using charcoal- casein agar (CCA) with 5% blood and cephalexin. Our work aimed to determine how different concentrations of cephalexin as a selective component would affect the growth activity of the CCA medium for the primary isolation of clinical B. bronchiseptica isolates and their growth intensity. It has been established that it is optimal to freeze the selective additive cephalexin in the medium of the CCA for the detection of clinical isolates of B. bronchiseptica at a concentration of 4 mg/ml. The yield of microbial cells to B. bronchiseptica strain No 16K from 1 ml of CCA core with the addition of cephalexin at a concentration of 4 mg/100 ml is 5.99 ± 0.34 billion. And when cephalexin is administered at a concentration of 6 mg/100 ml, the yield of microbial cells to the B. bronchiseptica strain No. 16K per 1 ml of the core is 5.38 ± 0.44 billion (p ≤ 0.05). There is a 10.35 % lower yield of microbial cells in the B. bronchiseptica strain No 16K from the CCA middle when cephalexin is added at a concentration of 4 mg/100 m. The concentration of cephalexin in the body center of CCA is 6 mg/100 ml or more and is inhibitory to the growth of B. bronchiseptica, therefore such a concentration in the body in the form of a selective additive cannot be used. The study results show that the use of a selective cephalexin supplement at a concentration of 4 mg/ml can reduce the time for isolation of clinical isolates of B. bronchiseptica by 2-4 days due to inhibition of the growth of extraneous nasopharyngeal microflora and significantly simplify the isolation of pure culture from sick animals
Palazzo Pitti fra Sette e Ottocento / Pitti Palace between the 18th and 19th centuries
Authors: Matracchi Pietro
Published: December 2024

Il tema della piazza viene affrontato a partire dall’antefatto, ovvero dalle particolari condizioni orografiche in cui è sorto il primo nucleo di palazzo Pitti, sorto tra due costoni rocciosi che ne hanno determinato l’orientamento e la posizione a margine della Firenze d’oltre Arno.
Dopo numerose proposte elaborate senza esiti tra i secoli XVI e XVII, con il progetto di Giuseppe Ruggieri, si costruisce (1764-1765) il rondò delle Carrozze, dotato di una loggia e una terrazza antistante ad arco di cerchio. Si trova così una soluzione per la piazza che sorge su un piano notevolmente inclinato dell’ultima propaggine a valle della collina di Boboli.
La ricerca ripercorre le vicende dei cantieri che si susseguono dal XVIII secolo fino all’intervento di Pasquale Poccianti e alla successiva definizione del torrino del rondò di Bacco che conduce alla Galleria Palatina, mettendone in luce il complesso percorso di proposte e varianti che si sono susseguite nel tempo, attuando anche rilevanti cambiamenti di parti già eseguite.

The theme of the square is approached by considering its backstory, namely the specific orographic conditions under which the first core of the Pitti Palace was built, standing between two rocky ridges that determined its orientation and position on the edge of Florence beyond the Arno.
After numerous unsuccessful elaborate proposals between the 16th and 17th centuries, the Rondò delle Carrozze was built (1764-1765) to Giuseppe Ruggieri’s design and equipped with a loggia and a terrace in front of it in the form of a circular arch. Thus, a solution was found for the square,
which stands on a considerably sloping plane on the bottommost incline of the Boboli hill.
The research traces the events of the succession of construction sites from the 18th century up to Pasquale Poccianti’s intervention and the subsequent definition of the turret del Rondò di Bacco leading to the Palatine Gallery. It highlights the complex proposals and variants that followed one another over time, also resulting in significant changes to parts that had already been built.
