Authors: Dias Bernardo Zandomenico , Alvarez Cristina Engel de , Meneghetti Leila Cristina , Lara Arthur Hunold
Published: January 2024

Resumo Buscando ampliar a aplicação dos compósitos termorrígidos, esta pesquisa objetiva identificar as bioresinas e biofibras mais resistentes às intempéries, contribuindopara seu uso externo. Foram levantadas pesquisas experimentais sobre compósitos com matriz sintética ou vegetal e fibras vegetais ou híbridas, com diferentes processos de moldagem, geometrias de reforço, alinhamento e tratamento das fibras e frações fibras/matriz. Buscou-se trabalhos que estudaram as resistências à tração e à flexão; a absorção de água dos compósitos em 24h de imersão e até a saturação; e sua retenção da resistência mecânica após envelhecimento. Investigou-se a influência do tipo de matriz e de fibra e de suas frações nessas propriedades. Resultados indicam que compósitos de matriz vegetal absorvem menos água em 24h, e que compósitos com linho, sisal ou cânhamo possuem a menor absorção de água na saturação e maior retenção da resistência à tração após o envelhecimento. Isto é, aparentemente esses compósitos sofrem menos danos devido às intempéries, possuindo maior potencial para uso externo. Mas, independentemente da fibra, conforme sua quantidade aumenta, diminui a retenção da resistência à flexão dos compósitos, limitando sua aplicação.
A panorama of Brazilian social housing research: scope, gaps and intersections
Authors: Muianga Elisa Atália Daniel , Kowaltowski Doris Catharine Cornelie Knatz
Published: January 2024

Abstrac Social Housing (SH) is investigated worldwide, especially in emerging economies. However, SH literature demonstrates that there are still barriers to achieving the real benefits of those programmes. Brazilian SH programmes have positively reduced housing deficits and the vulnerability of low-income populations. However, studies developed in Brazil also reveal the negative impacts of SH. Investigating the reason for the recurrence of negative impacts is fundamental to gaining a stronger understanding of the causes and scope of SH problems. Moreover, state-of-the-art studies may support the development of actions to mitigate those problems. Thus, this study aims to categorise the major topics studied on SHs, identify and evaluate SH main failures and impacts, analyse intersections of topics, and understand their scope. A systematic review and literature mapping were applied to analyse SH studies. Although evidence emphasises significant advances in SH production, results demonstrate the intersecting panorama of occurrences that cause negative impacts and stress the need for investments and the implementation of housing public policies aligned with societal interests to improve SH.

Neste âmbito, esta pesquisa tem por objetivo delinear as fronteiras do conhecimento e identificar direções de pesquisa futuras no que diz respeito aos usos do BIM para fins de gestão, operação e manutenção de instalações. Foi empregado um método misto de revisão que associou a análise cientométrica e revisão sistemática da literatura. Para condução da revisão inicialmente foram identificadas 4050 publicações da base de dados Scopus, que foram filtrados por meio do protocolo PRISMA e resultaram em 1004 publicações a serem analisadas. A frequência de fontes e citações e as redes de coocorrência de palavras-chave, de coautoria e de países compuseram a primeira análise. Em seguida, a análise sistemática do conjunto de dados foi realizada com o agrupamento das pesquisas em oito categorias diferentes. Como resultado, foi possível identificar que o campo “BIM para gestão, operação e manutenção das instalações” está em crescimento e que as finalidades de aplicação neste âmbito têm sido ampliadas, além de haver uma associação promissora das tecnologias emergentes com o BIM para este fim.
Efeito da variação das características higrotérmicas do concreto no comportamento higrotérmigo de uma parede
Authors: Silva Fernanda Belizario , Brito Adriana Camargo de
Published: January 2024

Resumo Simulações computacionais higrotérmicas consideram trocas transientes e simultâneas de calor e umidade entre os elementos construtivos e o ambiente, sendo uma ferramenta importante de apoio ao projeto e à avaliação de desempenho de edifícios. Essas simulações requerem como dados de entrada a descrição do elemento construtivo, as condições ambientais às quais ele está exposto e as características higrotérmicas dos materiais. Este artigo apresenta uma análise exploratória dos resultados da simulação higrotérmica de uma parede de concreto variando-se as características higrotérmicas do material. As condições ambientais internas foram obtidas utilizando o EnergyPlus™ e a simulação higrotérmica foi feita no WUFI® Pro, com pós-processamento no WUFI® Bio para avaliar o risco de ocorrência de fungos emboloradores. Houve diferenças significativas no comportamento higrotérmico das paredes em função da variação das características higrotérmicas dos materiais, sobretudo para o tipo de concreto cuja função de transporte capilar mostrou-se diferente dos demais. Os resultados indicam a importância de analisar as características e funções higrotérmicas para simulações higrotérmicas e a necessidade de sua determinação experimental para os materiais de construção brasileiros.
Mixed construction and demolition powder as a filler to Portland cement: study on packaged pastes
Authors: Oliveira Dayana Ruth Bola , Proença Melissa Pastorini , Marques Filho José , Possan Edna
Published: January 2024

Abstract The aim of this study is to explore more sustainable approaches by replacing Portland cement (OPC) with recycled mixed powder (RMP) derived from construction and demolition waste (CDW), with a focus on reducing carbon emissions. The CDW was subjected to grinding and sieving until a fraction <0.15 mm was obtained. The particles were then thermally activated at 800°C in a muffle for 0.5, 1, 2, and 3 hours. The OPC replacement levels by RMP were defined based on the particle packing method, ranging from 0 to 65%. The study was carried out on pastes with a water/fines ratio ranging from 0.07 to 0.14 and superplasticizer admixture (SP), evaluating the compressive strength at 28, 63, and 91 days. The mechanical and environmental performance of Portland cement pastes composed with RMP showed compressive strength higher than the reference, reaching 37 MPa for a 45% replacement content at 28 days, reducing the CO2 emissions per m³ of paste by up to 53%. This study suggested that the treatment and packaging RMP particles may potentially increase the mechanical and environmental performance, making it an alternative to promote the circular economy and low-carbon cement.
Functionally graded concrete: porosity gradation to enhance durability under carbonation
Authors: Ribeiro Daniel Veras , Silva Adriana dos Santos , Dias Cléber Marcos Ribeiro
Published: January 2024

Abstract The present paper evaluated the potential application of the functionally graded material (FGM) concept to develop more durable concrete to carbonation, one of the main degradation mechanisms of reinforced concrete structures. Accelerated carbonation tests with controlled temperature (27 ( 2°C), CO2 concentration (3 ( 0.5%) and humidity (65 ( 5%) were carried out in homogeneous concretes and with functional gradation in which the porosity of the material was varied across the slices. For the manufacture of graded concrete specimens, concretes with water/cement ratios equal to 0.35, 0.45, and 0.55 were produced, with lower porosity (w/c = 0.35) close to the surface of the specimen. The advance of the carbonation front was evaluated after 8, 9, 10, 14, and 24 weeks of accelerated exposure, using the chemical indicator phenolphthalein. The results show that the functionally graded concrete had a carbonation coefficient (K) slightly higher than that of the concrete with a w/c ratio equal to 0.35 (1.71 and 1.54 mm.week-0.5, respectively) and much lower than concrete with water-cement ratio equal to 0.45 (2.31 mm.week-0.5) and 0.55 (3.78 mm.week-0.5). This demonstrates that functional grading can be an efficient method to increase the durability of concrete elements subject to carbonation.

Resumo Amadeira lamelada colada cruzada (MLCC) é um produto empregado na forma de painéis que apresenta como desafio a consideração conjunta da disposição ortogonal de lamelas com o comportamento ortotrópico da madeira. Para avaliar o comportamento mecânico de painéis de MLCC, em flexão simples, é possível recorrer a teorias de placas, métodos numéricos e simplificados. Dentro desse contexto, este trabalho se propôs a analisar as tensões, normais e de cisalhamento, bem como os deslocamentos verticais em um dado painel de MLCC por meio de três teorias de placas, três métodos simplificados, método dos elementos finitos e um método analítico proposto. Para o estudo, foi considerado um painel de MLCC com cinco camadas de 20 mm de espessura, inicialmente quadrado com lados de 3 m, sendo, posteriormente, realizadas análises paramétricas da razão entre as dimensões em planta. Com as análises estruturais, foi possível a obtenção das tensões, bem como os deslocamentos verticais do referido painel. As análises paramétricas realizadas permitiram averiguar a sensibilidade do painel de MLCC proposto, em termos de tensões e deslocamentos verticais, frente às variações da razão entre as dimensões em planta do painel.

Published: January 2024

Resumo Para o entendimento do comportamento ao cisalhamento de vigas de concreto reforçadas com fibras de aço e sem a utilização de estribos, foram estudadas experimentalmente vigas por meio de ensaios de flexão. Os parâmetros analisados foram duas classes deresistência à compressão (30MPa e 45MPa) e três quantidades de fibras (40kg/m³, 60kg/m³ e 80kg/m³), além de um traço de referência. Uma comparação analítica dos resultados experimentais com modelos de cálculos de regulamentações normativas e de trabalhos científicos foi estudada para a previsão da força de ruína das vigas. Os resultados experimentais demonstraram ganhos na resistência última ao cisalhamento proporcionado pelas fibras de aço, evidenciando seu grande potencial frente ao esforço de cisalhamento. O modo de ruína das vigas não foi alterado para as quantidades de fibras e classes de resistência estudadas. Porém, maior capacidade de carga e de deformação foi evidenciada com o aumento da quantidade de fibras e do fck. O modelo da norma brasileira NBR 16935 (ABNT, 2021a) mostrou excelente resultado na previsão da força de ruína das vigas do grupo C30.
Effect of self-healing in closing cracks from the sulfate attack in Portland, supersulfated and alkali-activated cement
Authors: Trentin Priscila Ongaratto , Luz Caroline Angulski da , Medeiros-Junior Ronaldo Alves de
Published: January 2024

Abstract Self-healing consists of closing cracks and recovering the watertight properties of cement-based materials and can occur by hydration of the materials of the mixture (autogenous) or by materials added to the mixture for this purpose (autonomous). This study consists of the use of stimulated self-healing as a way of mitigating sulfate attack (sodium and magnesium), with the evaluation of the influence of crystalline admixture in this process. For that, cycles of sulfate attack and self-healing (by wetting and drying cycles in water) were performed, aiming to evaluate the behavior of mortars with three types of cement: Portland, supersulfated, and alkali-activated. The results showed that self-healing was not sufficient to close cracks due to sulfate attack. This behavior was associated with the hypothesis that the high calcium content of the crystalline admixture reacted with the sulfates and formed expansive products, increasing the attack rate.
Incorporação de lodo têxtil em materiais de construção civil: uma busca sistemática

Published: January 2024

Resumo Olodo têxtil é um resíduo do tratamento do efluente das lavanderias têxteis e sua incorporação em materiais alternativos tem sido proposta como possibilidade para sua destinação. Foi realizada uma busca sistemática na literatura nesta perspectiva, visando observar as concentrações de material residual e seu preparo, as matrizes utilizadas, o desempenho tecnológico e imobilização do resíduo têxtil. As matrizes empregadas foram argamassas, concretos e tijolos cerâmicos, sendo observados, de maneira geral, efeitos deletérios nas características mecânicas dos materiais produzidos. Em concretos e argamassas, a finura impactou no aumento da demanda de água, o que elevou a porosidade das misturas; e a matéria orgânica e metais pesados, na hidratação do cimento. Estudos recentes propuseram, então, o pré-tratamento do material residual como uma alternativa favorável. Incrementos na porosidade também ocorreram nos tijolos cerâmicos, porém, devido ao elevado teor de matéria orgânica. Quanto a imobilização do resíduo, os materiais cimentícios apresentaram desempenho satisfatório; já os tijolos cerâmicos, obtiveram alguns resultados fora dos limites normativos. Portanto, é necessário ampliar as discussões quanto ao pré-tratamento realizado no lodo têxtil, bem como seus impactos no desempenho mecânico e ambiental.
New insights into a poorly known parasite, Dero lutzi (Oligochaeta: Naididae), associated with tree frogs of the genus Scinax: morphological evaluation and genotypic data
Authors: Silva Isabela Caroline Oliveira da , Soares Priscilla , Malta Lennon , Paiva Fernando , Ferreira Vanda Lúcia , Oliveira Carina Elisei de , Tavares Luiz Eduardo Roland
Published: January 2024

Abstract The oligochaete Dero lutzi follows a life strategy that alternates between free-living periods in aquatic environments and endoparasitic phases. Most occurrences of D. lutzi in anurans are reported in species with arboreal habits, with studies limited to the recording of the oligochaete’s presence in the host. Our study recovered specimens of D. lutzi from the tree frogs Scinax fuscovarius and Scinax. nasicus. We performed a morphological assessment of the parasite using light microscopy, for the first time, scanning electron microscopy. Molecular characterization of D. lutzi was carried out using the mitochondrial gene 16S rRNA and the nuclear gene 28S rRNA. Additionally, a phylogenetic tree was constructed to assess the species´position in relation to other group members. In our results, we confirmed the phenotypic morphological characteristics of the endoparasitic phase of D. lutzi. We also presented its phylogenetic position with other oligochaetes in the group, demonstrating the proximity between the endoparasite D. lutzi and the free-living oligochaete D. superterrenus.

Published: January 2024

Abstract During studies on fish parasites, two new species of Anacanthorus were found parasitizing serrasalmid fishes, Anacanthorus simpliciphallus sp. n. from the hybrid Piaractus mesopotamicus x Piaractus brachypomus and Anacanthorus brandtii sp. n. from Serrasalmus brandtii. Anacanthorus simpliciphallus sp. n. resembles Anacanthorus reginae in the morphology of the male copulatory organ (MCO) and accessory piece but differs from A. reginae in terms of the smaller size of the accessory piece, which corresponds approximately half the size of the MCO and by the presence of a conspicuous metraterm, with a membranous terminal region. Anacanthorus brandtii sp. n. differs from Anacanthorus scapanus by the expansion of the accessory piece, from Anacanthorus jegui by the ratio MCO (male copulatory organ) /AP (accessory piece) and by the expansion of hook shank, from Anacanthorus sciponophallus and A. reginae by the ratio MCO/AP. Anacanthorus brandtii sp. n. can be distinguished from A. reginae and A. simpliciphallus sp.n. by the size of hooks which is similar in A. reginae and A. simpliciphallus sp. n. and dissimilar in A. brandtii sp. n. The two new species also differ from each other by the expansion of shank.
Influence of thermal strain on concrete spalling
Authors: Klimek André , Stelzner Ludwig , Hothan Sascha , Zehfuß Jochen
Published: January 2024

Understanding the susceptibility to spalling of concrete members in case of fire is important to evaluate the residual load-bearing capacity. The investigations of the spalling phenomenon of a concrete mixture using real scale members are necessary but expensive to carry out. Reducing the specimen size leads to an increase of boundary effects that can result in a reduced spalling or absence of spalling. In this study, fire tests were carried out on unrestrained, single-sided exposed, cuboid shaped specimens (0.6 m $$\times$$
×
0.6 m $$\times$$
×
0.29 m) as well as unrestrained and steel ring restrained cylindrical specimens (Ø = 0.47 m, h = 0.29 m), which induce different boundary conditions. These fire tests were carried out on two ordinary concrete mixtures. The two mixtures differ only in the type of aggregates (quartz gravel and basalt grit) and were used to investigate the influence of the thermal expansion of the aggregate on the spalling behaviour of the concrete. The results show a significant increase of the spalling depth due to the restrained thermal expansion achieved by the applied steel rings. Additionally, the type of aggregate has a direct influence on the spalling behaviour of a concrete mixture. The reduction of the boundary effects by the steel rings recreate the test conditions in the centre of a large concrete member. Thus, this type of specimen is suitable to determine the susceptibility to spalling of a material (screening-tests) as preliminary investigations to full scale fire tests.
A comprehensive life-cycle assessment of plastic mulching for maize
Authors: Al-Dawood Zahraa , Tatan Bushra , Mootassem Ruba El , Mortula Md Maruf
Published: January 2024

While plastic mulch (PM) can increase crop yield, there are negative environmental impacts associated with the production, use and disposal of PM films. There is currently a gap in the literature on the negative impacts of PM throughout its entire life cycle, with most studies focusing on the global warming potential (GWP) only. The objective of this study is to conduct a life-cycle assessment (LCA) of PM to investigate the environmental impacts of all stages of mulching. The LCA was conducted using the SimaPro with data obtained from the relevant literature and ecoinvent database. The system boundaries include the production, transportation, installation, operation, removal and disposal of PM. The results reveal that the field operation of PM has the highest impact in GWP. A sensitivity analysis was also conducted and the GWP impact was observed to be sensitive to changes in carbon dioxide and net ecosystem carbon dioxide budget. The production of PM has the highest impact in abiotic depletion, but this impact can be reduced through energy recovery. Incineration yields the least harmful impacts, but the results of the study may vary depending on the exact disposal method. The impact of PM can be mitigated through proper waste management and mitigation measures, including regulations on disposal.
Green hydrogen production using proton membrane electrolysis of clean drinking water
Authors: Søgaard-Deakin Jasmin , Xydis George
Published: January 2024

With the EU’s green strategy and its member countries making a conscious effort to move away from fossil fuels and cut greenhouse gas emissions, there has been an uptick in technologies that produce green energy. Power-to-X has become an important topic in recent times, due to the so-called emission-free process of creating hydrogen from excess renewable energy. This research investigated this claim of being emission-free by analysing the method of obtaining extremely clean (pure) drinking water to produce hydrogen. A linear equation was produced that determines the carbon dioxide (CO2) intensity per kilowatt-hour of electricity used in producing a kilogram of water used to produce hydrogen. It was found that carbon dioxide emissions were produced by small-, medium- and large-capacity projects based in Denmark. Indicatively, for a 1 GW project facility, it was calculated that such a plant can produce 160 161 kg of carbon dioxide per year, so apparently, nothing comes without a cost.
Intermediality, Hybridity, and Disruption, in the Operas of Wagner and Verdi
Authors: Broadhurst Sue , Harvey Neil Morris
Published: January 2024

‘Intermediality’ and ‘Hybridity’ are often discussed as if they apply only to creative works of the last century and of the future, and that their use necessarily entails the presence of contemporary technology. But in our careers as academic, author and artist, we are increasingly reminded of how the most innovative work in performance almost inevitably resonates with that of the past, sometimes quite remote past, and with genres which may, today, frequently seem conservative in their realisation. Recently we have come to see that many of our discussions could relate to a complex, and of course, deeply hybrid genre of performance, so thoroughly embedded in our culture that we no longer perceive how strange and problematic it is, that is Opera. 
¿Hacia una “nueva” cuestión campesina en Argentina?
Authors: Colla Julia L. , Valverde Sebastián
Published: January 2024

En las últimas cuatro décadas la ruralidad argentina ha cambiado, y junto con ella las condiciones de subordinación del campesinado al sistema capitalista. En el presente artículo nos proponemos abandonar los falsos caminos a los que conduce elaborar modelos abstractos de lo campesino como “concepto”; nuestro argumento se basa en desarrollar las características que tienen productoras y productores directos en el actual contexto que les toca vivir. A través de una investigación documental de los estudios sociales agrarios, elaboramos un corpus con los principales aportes de trabajos académicos y estatales que reúnen las problemáticas socioeconómicas, políticas y culturales similares en torno al campesinado y lo catalogamos como una “primera cuestión campesina”, concentrada en el periodo 1970-2000. Luego, se plantean seis tesis que atraviesan la experiencia social actual de las producciones familiares: la descomposición y exclusión social; el giro ecoterritorial; el surgimiento de movimientos sociales; la reetnización; la agroecología; y la soberanía alimentaria y la estatalidad. Se concluye que estos tópicos han inaugurado una “nueva cuestión” que apunta a la construcción de líneas de investigación con nuevos consensos teóricos y epistemológicos para comprender al campesinado argentino realmente existente.
El excedente de fuerza de trabajo en Argentina: un análisis desde la economía feminista
Authors: Alonso Virginia Noemí , Rodríguez-Enríquez Corina
Published: January 2024

En este artículo se retoma el concepto de excedente de la fuerza de trabajo tal como se entiende desde el pensamiento económico latinoamericano, por su importancia al señalar las dificultades del capitalismo para incorporar a las personas en empleos de calidad y explicar la reproducción de las desigualdades. A fin de contribuir al estudio de la exclusión laboral de las mujeres dentro de la región, se persiguen dos objetivos. El primero: construir una propuesta teórico-metodológica para estudiar el excedente de la fuerza de trabajo mediante la relectura del abordaje estructuralista desde la economía feminista. Con el segundo se propone analizar, a partir de este marco adaptado, la evolución del excedente de la fuerza de trabajo, así como la política asistencial argentina que pretende regularlo y su vínculo con la reproducción de las desigualdades de género en el ámbito nacional entre 2003 y 2019. Para ello se realiza un análisis documental y estadístico de distintas fuentes. Los resultados permiten constatar la persistencia estructural de la exclusión y la desigualdad de género producto de la articulación entre los rasgos laborales del estilo de desarrollo argentino y el patrón de política asistencial consolidado. Dicho patrón se apoya en las transferencias monetarias condicionadas y resulta funcional a la feminización del excedente de la fuerza de trabajo durante las dos primeras décadas del siglo XXI.
Neoliberalismo autoritario, élites económicas y reforma educativa en México, 2013
Authors: Bojórquez-Luque Jesús
Published: January 2024

El objetivo del presente artículo es analizar la reforma educativa en México focalizando la sinergia de intereses entre las élites económicas y la clase política. Sobre la base de una metodología cualitativa, de índole exploratoria y descriptiva, se examina el neoliberalismo autoritario; este concepto establece que atravesamos una etapa del capitalismo, en la cual los Estados han aumentado sus rasgos autoritarios en la toma de decisiones sin tener en cuenta el consenso de la población, con el fin de apuntalar los procesos de acumulación de capital. Lo anterior les ha permitido generar andamiajes jurídicos y reforzar los aparatos represivos con el fin de crear inmunidad ante la protesta social, renunciando a la negociación y a la cooptación; todo ello en alianza con las élites económicas y financieras. Los resultados demuestran que la reforma educativa fue impuesta por las élites económicas en acuerdo con el poder político, sin mediar una postura de negociación con el profesorado. Apoyados por los medios de comunicación masivos, se culpó al personal docente del fracaso del sistema educativo, creando un clima de linchamiento, sobre todo contra quienes salieron a manifestarse en el espacio público. Se concluye que la reforma educativa y su imposición, lejos de pretender una mejora en la calidad, buscaba controlar al magisterio y consolidar la precarización laboral, una medida distintiva del modelo neoliberal.
De la reforma electoral plurinacional a la democracia intercultural en Bolivia: el caso del pueblo mosetén
Authors: Díaz-Villanueva Augusto
Published: January 2024

En el presente artículo se discute acerca de los avances, en términos normativos y de democratización, de los mecanismos y las dinámicas del sistema de participación política de los pueblos indígenas originarios campesinos de Bolivia. El objetivo de tal discusión es representar el funcionamiento del ensamblaje institucional entre la Asamblea Legislativa Departamental de La Paz y los usos y costumbres del pueblo indígena mosetén. Para ello, se parte de una visión que considera al Estado Plurinacional resultante de un proceso de construcción estatal en el que los pueblos indígenas originarios campesinos han luchado por la representación y el reconocimiento. Se realiza un análisis sistemático de las innovaciones institucionales introducidas a partir del Estado Plurinacional, las cuales implican una reforma electoral. Se discute el paradigma de la democracia intercultural y se lo operativiza mediante la noción de ensamblaje para realizar una aproximación al caso de interés a través de una caracterización y de entrevistas a actores clave. Se concluye que los mecanismos introducidos en Bolivia abren paso al reconocimiento de otras democracias no liberales, además, que es posible la inclusión de minorías étnicas históricamente excluidas. Sin embargo, también se ilustran los obstáculos y los desafíos que afrontan las poblaciones indígenas para consolidar lo descrito en la ley.
Mapeamento das associações que atuam como instrumentos de governança para as RPPN nos estados brasileiros

Published: January 2024

Este artigo é sobre um mapeamento das associações de Reserva Particular do Patrimônio Natural (RPPN), unidade de conservação privada destinada a proteção ambiental. As associações de RPPN são organizações que reúnem os associados/proprietários destas unidades na busca pelo fortalecimento da causa da proteção ambiental por propriedades privadas. Por meio de análise documental e entrevistas com pessoas diretamente ligadas as associações, este trabalho buscou observar a variação ocorrida no número de associações pelo Brasil, nas últimas duas décadas, e identificar os principais desafios enfrentados por estas instituições. Pouca bibliografia sobre as associações de RPPN fazem deste trabalho original no levantamento destas questões. O resultado mostra que o número de associações pelo Brasil variou de 17 para cinco, atualmente. Dentre as razões apontadas que dificultam a gestão e manutenção destas está o fator financeiro, a falta de recursos para as atividades cotidianas. Paradoxalmente, é por meio destas associações que a causa da proteção ambiental por meio de propriedades privadas pode ter força política que leve a uma alteração do cenário atual. Compreender as dificuldades enfrentadas por estas instituições fortalece a causa da proteção ambiental por propriedades privadas, contribuindo diretamente com a conservação do meio ambiente.

Sarah Bernhardt e le altre. La physionomie nerveuse des femmes artistes secondo Enrico Ferri
Authors: Serpico Francesco
Published: January 2024

A partire dalla seconda metà dell’Ottocento, la sessualità femminile fu al centro di un complesso intreccio tra il discorso medico e quello giuridico al fine di iscrivere il corpo della donna in una fitta maglia di prescrizioni definita dalla sua “naturale” funzione di moglie e di madre. All’interno di questa prospettiva, l’articolo si propone di analizzare un contributo di Enrico Ferri, leader socialista e tra i principali esponenti della Scuola positiva, incentrato sull’analisi della personalità della “divina” Sarah Bernhardt. Lontana dagli stereotipi di genere della passività e dalla sottomissione, la figura iconica della diva sembrava riassumere in sé nuovi e destabilizzanti modelli di identificazione della sessualità e del desiderio femminile contribuendo così a rivelare le ansie ed i timori sottesi al processo di modernizzazione sociale nell’Europa fin de siècle.
Laundering Illicitly Trafficked Cultural Property and Criminal Law Control over the Import and Export of Artworks and Antiquities
Authors: Visconti Arianna
Published: January 2024

The last decade has been characterised by a growing attention to the criminal dimension of the art and antiquities market. This process culminated in the adoption of the first suppression convention aimed specifically at cultural property trafficking ever entered into force, after the failed attempts dating back to the Eighties and Nineties. After briefly summarising the reasons for this shift in paradigm, the paper delves into the crucial issue of laundering of cultural items of unlawful origin, as addressed by the 2017 Council of Europe Convention, with a specific focus on the crucial role played by international circulation. To this effect, a summary of the main national approaches to the export and import of cultural property is offered for the reader’s consideration, together with some reflections on the growing importance of provenance research and provenance documentation as tools to improve transparency in the market and reduce its ‘grey’ nature.

Carbapenemase-producing Enterobacterales (CPE) are one of the most urgent threats to human healthcare globally. Our study aimed at optimizing the chromogenic agar method of screening for CPE with and without selective enrichment to isolate CPE from animal feces. The selective enrichment step did not result in any increased recovery of CPE from companion animals with NDM-5 E. coli, which suggests that enrichment broth may not be necessary for outbreak surveillance testing. Therefore, the selective enrichment step is optional, however, this method may not be generalizable to the detection of all types of CPE in fecal specimens from companion animals.

Duchenne muscular dystrophy is a genetic, X-linked, relentlessly progressive disease. Due to a genetic defect, the reading frame is disrupted during the synthesis of the dystrophin protein, resulting in its loss of functionality. As a result of the absence of dystrophin, there is a gradual destruction of muscle cells. In recent years, pathogenetic therapy for Duchenne muscular dystrophy has become available in Russia. However, the therapy available in Russia is specific, depending on the mutation variant, and may be recommended for approximately one third of patients. This article discusses the features of exon-skipping therapy, the clinical effectiveness, and safety of this group of drugs. The effectiveness and safety of the therapy are demonstrated through a clinical case of a patient receiving one of the drugs in this group.

Authors: Ermilov E. A. , Isaeva N. V.
Published: January 2024

Background. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that causes paralysis of muscles due to degeneration of motor neurons. According to available data, the incidence of ALS in different regions of the world is from 0.6 to 3.8 per 100,000 population per year. Data obtained during the study of the epidemiology of ALS at the regional level can be used in planning medical resources, in particular, calculating the necessary respiratory equipment and funds for nutritional support.Aim. Clinical and epidemiological analysis of ALS cases registered in the Krasnoyarsk region for the period 2018–2022.Materials and methods. A clinical and epidemiological analysis of ALS cases registered in the Krasnoyarsk region from 2018 to 2022 was conducted. To do this, we used data from the specialized office of neuromuscular pathology of the Regional Clinical Hospital in Krasnoyarsk and the Krasnoyarsk Regional Medical Information and Analytical Center. Diagnosis verification was carried out in accordance with the generally accepted El Escorial and Gold Coast criteria. The functional state and degree of neurological deficit were assessed using the ALS-FRS-R scale.Results. Over the period from 2018 to 2022, 78 cases of ALS were registered. The incidence rate was 0.54 cases per 100,000 population per year. In 2022, the prevalence rate was 1.16 cases per 100 thousand population. The time from symptom onset to diagnosis of the disease ranged from 4 to 57 months, with the average time to diagnosis being 17 months. Most patients were diagnosed with ALS when their ALS-FRS-R score decreased by 7–11 points. The division of patients into groups of rapid, moderate, and slow diagnostic correlates with life expectancy. Patients who are diagnosed quickly have a higher rate of disease progression, which results in a low life expectancy.Conclusion. The creation of specialized centers will improve the diagnosis and management of patients with ALS and plan the costs of palliative care. The increase in the incidence and detection of ALS emphasizes the need to develop new approaches to the treatment and rehabilitation of patients with ALS.
Pudendal neuralgia
Authors: Borodulina I. V. , Kovalev G. V.
Published: January 2024

Pudendal neuralgia is the most common type of neurogenic chronic pelvic pain and is defined as a chronic neuropathic pain syndrome caused by compression and/or neuropathy of the genital nerve and localized in the area of its sensory innervation. Pudendal neuralgia negatively affects daily activity and reduces the quality of life. The diagnosis of pudendal neuralgia is established on the basis of clinical manifestations and examination data in accordance with the Nantes criteria, while instrumental methods (ultrasound, magnetic resonance and computed tomography, electrodiagnostic methods) do not allow verifying the diagnosis due to significant limitations. Currently, there are no unambiguous recommendations and standards for the treatment of pudendal neuralgia, however, a combination of different methods and a personalized approach allows in some cases to achieve significant success and long-term pain control. The article highlights in detail the anatomical features of the pudendal nerve, examines the possibilities and stages of diagnosis of pudendal neuralgia, and provides an overview of therapeutic methods from the standpoint of evidence-based medicine.

We report an 8-year-old patient with glutaric aciduria type 1 associated with compound heterozygous mutations c.1204C>T (p.Arg402Trp) and c.547C>T (p.Ser216Leu) in GCDH. Clinical case illustrates the difficulty in diagnosing this hereditary disease, its mimicry of neonatal hypoxic-ischemic encephalopathy and cerebral palsy. The timeliness of early diagnosis and initiation of specific therapy makes it possible to improve the condition of patients.
An effective approach for analysis of shoreline change and determination of its future location using satellite imagery: A case study of the Lake Burdur, Turkey
Authors: BAŞ Nuray
Published: January 2024

Lake shoreline changes can have a significant impact on the biodiversity and ecosystems of wetland. This study was aimed to calculate the coastal change of Lake Burdur in Turkey during the elapsed period from 2013 to 2023. Within this framework both remote sensing based aproach and Digital Shoreline Analysis System (DSAS) was performed using Landsat-7 (TM) and Landsat-8 (OLI) images. To estimate shoreline change rates along the coastal zone, statistical parameters such as End Point Rate (EPR), Linear Regression Rate (LRR), and Net Shoreline Movement (NSM) were calculated. A hybrid algorithm, Normalized Difference Vegetation Index (NDVI) and Tasseled Cap Analysis, is utilized to emphasize the distinction between the lake bodies and coastal zone. The maximum shoreline change in the northeast part of the lake was observed, and it resulted in a change of 543.12 m/yr for EPR and 610.07 m/yr for LRR statistics in the 2013-2023 time period. The lake to land position has only been observed in a small amount which are resulted in for EPR -4.91 m/yr. and -3.17 m/yr for LRR statistics. The lake area decreased from 139 km2 to 118 km2 between 2013 and 2023. The results indicate that if the decision-maker does not measure, the area of the lake will be lost by 14% until 2033 and 27% until 2043.
CHANGES IN WATER BALANCE COMPONENTS WITHIN THE LEFT BANK OF THE MIDDLE DNIPRO IN 1961-2020
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, S.P. S.P.
Published: January 2024

The article examines the changes in water balance components within the left bank of the Middle Dnipro during two hydroclimatic periods, 1961-1990 and 1991-2020. The research also covered six key river basins on the left bank of the Middle Dnipro, including Psel, Sula, Vorskla, Trubizh, Supii, and Zolotonoshka. The examination of the modifications in the components of the water balance during the period of the climatic norm from 1961-1990 and the modern climatic period from 1991-2020 revealed a decrease in the average long-term values of precipitation in general by -7.3 mm, river runoff by -5.2 mm, and total evaporation by -2.1 mm. The amount of rain on the left bank of the Middle Dnipro was different in each river basin. In the Psel and Sula basins, there was a significant increase in precipitation, with a difference of 18.4 mm and +0.9 mm, respectively. In the Vorskla, Zolotonoshka, Trubizh and Supii basins, there was less rain by -2.2 to -51.7 mm. The opposite scenario was observed in the variation of total evaporation in the respective river basins. Thus, in the three largest river basins of the Psel, Sula and Vorskla, it increased from 5.6 to 26.7 mm, in all other basins the total evaporation decreased from -0.3 to -47.6 mm. But despite various changes in precipitation and total evaporation, there is a reduction in the volume of river runoff from -1.6 to -8.6 mm. The negative dynamics of river runoff indicators are attributed to negative cumulative values of precipitation and total evaporation. The main cause of these changes is the increase in the average annual air temperature across all studied basins by +1.2 °C, leading to an increase in climate aridity indicators within the left bank of the Middle Dnipro by +0.9 %. Similarly, there was a drop in the runoff coefficient by 0.9 %. In essence, changes in water balance components in the studied area result in more water volume from atmospheric precipitation going towards total evaporation, leading to a loss of the water volume that forms river runoff. This serves as a clear example of the influence of the global increase in air temperature on the reduction of water volume in rivers within the left bank of the Middle Dnipro.
STUDY GUIDE ON HYDROECOLOGICAL ASPECTS OF WATER SUPPLY AND SEWERAGE – A JOINT PROJECT BETWEEN TWO UNIVERSITIES (2023)
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Grebin V.V.
Published: January 2024

The article presents and analyzes the study guide “Hydroecological aspects of water supply and sewerage”, published in 2023 by V.K. Khilchevskyi (Taras Shevchenko Kyiv National University), M.R. Zabokrytska and V.Yu. Stelmakh (Lesia Ukrainka Volyn National University). The study guide “Hydroecological aspects of water supply and sewerage” has 12 chapters, which can be conventionally structured into five parts: the role of the components of the chemical composition of water in human life (chapter 1); water resources and water use (chapter 2-3); technological aspects of water supply, rationing and control (chapter 4-7); technological aspects of sewerage, regulation and control (chapter 8-10); water supply and drainage in the cities of Kyiv and Lutsk (Chapter 11); water quality assessment of water bodies for water supply and environmental purposes (Chapter 12). The authors of the study guide emphasize that when using water objects for water supply, it is necessary to take into account the possibility of their contamination – the excess of pollutants or indicators of the physical properties of water in maximum permissible concentrations, which causes a violation of water quality standards. In Ukraine, there have been many changes related to both water monitoring and the regulatory framework for water quality assessment for various purposes, which is due to the course of integration with methodical approaches in this field in the European Union. A significant incentive for this process was the signing of the Association Agreement between Ukraine and the EU in 2014, which led to the reform of many spheres of activity, including those related to the management of water resources and their quality. The study guide is intended for students studying in the educational programs “Hydrology” and “Management and ecology of water resources” specialty 103 “Earth sciences”. It can also be useful for students of other educational programs of specialties 103 “Earth Sciences” and 106 “Geography”, in which they study issues of water resources, water supply and drainage.
