Background: The subtropical regions of Jammu and Kashmir face unique agricultural challenges due to their climatic conditions and irrigation needs. The integration of cereals, legumes and grasses into sustainable forage cropping sequences offer a promising solution to enhance both productivity and nutritional quality of livestock feed. This study aims to assess the nutritional quality of these diverse forage crops under irrigated conditions providing valuable insights for improving agricultural sustainability and livestock health in the region. By optimizing forage cropping systems, this research seeks to contribute to the development of resilient agricultural practices in the subtropics of Jammu and Kashmir.s Methods: The study was conducted at Research Farm, Division of Agronomy, SKUAST – Jammu during 2020 and 2021 focused on assessing sustainable forage cropping sequences for continuous high-quality green fodder production in subtropical irrigated zones of India. The experimental field had sandy clay loam soil with slightly alkaline pH, low organic carbon and nitrogen levels and medium availability of potassium and phosphorus. It comprised 24 treatments arranged in RBD and replicated three times with nutrient application following recommended practices. Result: The experimental results revealed that Multicut Sorghum + Maize with Root slips of Napier planted in July recorded significantly higher ADF, NDF, hemi cellulose and cellulose content at each cut which was statistically at par with Multicut Sorghum + Maize with Root slips of Setaria planted in July, Multicut Sorghum + Maize with Stem cuttings of Napier planted in January and Multicut Sorghum + Maize with Stem cuttings of Setaria planted in January during both the years of experimentation. However, significantly lowest ADF content was recorded with Multicut Bajra + Cowpea with stem cuttings of Setaria planted in January.
Scenarios for Negotiating a UN Framework Convention on International Tax
Authors: Heitmüller Frederik
Published: January 2025

Negotiations have started on a new United Nations (UN) Framework Convention on International Tax – a development that could shift the balance of power in international tax. This area has long been dominated by the Organisation for Economic Co-operation and Development (OECD) and G20 – the Convention could provide the UN with a more central role in shaping global tax policies. This process was set in motion in December 2022 by UN resolution 77/244, ‘Promotion of inclusive and effective international tax cooperation at the United Nations’. An Ad Hoc Committee was formed to develop the terms of reference (ToR) for drafting the Convention – this approved draft ToR in August 2024. The African Group at the UN are driving this effort, with support from much of the global South. The global North remains sceptical. The push for a new framework comes amidst a backdrop of increasing complexity in international tax standards, and a perceived imbalance in allocation of taxing rights between countries. A significant concern is that there is no political body to oversee the work of technical institutions like the Inclusive Framework. This has resulted in a disconnect between technical negotiations and political decision-making in some global South countries.

This research analyses discussions that took place in 2024. It distils the most important lines of conflict around negotiating the UN Framework Convention, and articulates the main scenarios for a way forward.

Este artigo apresenta algumas contribuições para o debate acerca dos assentamentos rurais e a análise do meio físico e do uso do solo. O objetivo geral desta pesquisa é analisar se os três assentamentos rurais de Silvânia, GO, estão em áreas que favorecem o desenvolvimento agropecuário das famílias assentadas e, consequentemente, garantem a elas possibilidades de alcançarem diversos pressupostos colocados pelo Instituto Nacional de Colonização e Reforma Agrária (INCRA), como direito à habitação, saúde, lazer, dentre outros. Para a realização deste estudo, utilizou-se, na metodologia, uma abordagem qualiquantitativa. A coleta de dados se deu por meio do levantamento bibliográfico e cartográfico. Foram considerados para abordagem do meio físico aspectos do relevo com ênfase na declividade, redes de drenagem e classes de solo. Quanto ao uso e à ocupação do solo, foram abordadas as classes de uso, as áreas de preservação permanente (APP), a presença de pivôs e reservatórios nos canais fluviais e o tamanho das propriedades. A análise dos dados foi realizada por meio de estatística descritiva, pela elaboração de mapas que apresentam o meio físico e o uso e cobertura do solo nos assentamentos de Silvânia. Os resultados mostram que as características do meio físico e do uso e da ocupação do solo das bacias hidrográficas onde estão localizados os assentamentos de Silvânia não são impeditivas para o desempenho produtivo das famílias, o que permite a elas o alcance a diversos direitos fundamentais, bem como pode assegurar o desenvolvimento sustentável das famílias, mesmo que algumas demandem maiores investimentos produtivos, mais mão de obra e incentivos estatais do que outras.

Published: January 2025

A água potável encontrada na natureza está enfrentando escassez devido a fatores como degradação ambiental, crescimento populacional e aumento do consumo nas atividades econômicas. Este trabalho se concentra na viabilidade de captar e armazenar água da chuva para irrigar o gramado do Estádio Pedro Pedrossian (Morenão) na Universidade Federal de Mato Grosso do Sul (UFMS), em Campo Grande, MS. O estudo envolveu uma análise das instalações do Estádio Morenão e a avaliação das oportunidades de captura e armazenamento de água da chuva. Foram aplicados métodos de dimensionamento, como Rippl e Simulação, para determinar o tamanho do reservatório. Projetos executivos e planilhas de custo foram desenvolvidos para o sistema de aproveitamento de água da chuva e irrigação automatizada, demonstrando ser uma opção viável. A análise econômica considerou dois cenários: o primeiro, com aproveitamento de água da chuva, obteve um período de retorno do investimento de 10,7 anos; e o segundo, sem aproveitamento de água da chuva, ou seja, somente com a implantação de um sistema de irrigação automatizada, mas que reduziria o consumo de água proveniente da concessionária, apresentou um período de retorno de 2,6 anos.

The use of natural ingredients in dental care, such as manginang which has become part of the Minang community culture, is considered an alternative dental care that must be created to overcome the negative impacts of dental care made from artificial materials. The core of this study is to change the manginang tradition towards logical verification through screening of bioactive compounds of gambir leaves (Uncaria gambir Roxb.) as antibiofilms against Streptococcus mutans. This study was conducted using an in silico strategy approach with the help of computer programs such as MOE v.09 and Chimera 1.13.1, as well as the Way2Drug site, protein information bank, and protox_ii. This study began with the collection of ligand information from the writing, followed by transformation into 2D and 3D designs. Other antibiofilm actions were decided using the QSAR procedure through the website (http://www.way2drug.com/PASSOnline/predict.php). The selected antibiofilm compounds were then followed by observing their affinity for the receptor (pdb id. 3AIB) using an atomic docking strategy. Finally, the ligand damage profile was observed to anticipate. The results of this study indicate that of the 41 identified gambir leaf compounds, there are 20 compounds that have the potential to have antibiofilm effects with quinnic acid having the highest score (Pa 0.703), while the compound with the strongest affinity for the receptor is chlorogenic acid with an affinity score (ΔGbinding) of -16.03 kcal/mol and an average of low toxicity (level IV-VI). However, of the 20 bioactive compounds of gambir leaves, only 5 compounds are predicted to have the same potential as the α-maltose control.
Practical Applications of Space-Time Fractional Diffusion in Naturally Fractured Reservoirs
Authors: Chen Chih , Chu Wei-Chun , Bermudez Leonardo
Published: January 2025

This study introduces a radial space-time fractional-diffusion (ST-FD) model, now adapted for Laplace space. This model incorporates dual-porosity factors and, when applied to well tests in naturally fractured reservoirs, addresses the effects of rock heterogeneity in fractured or fissured formations by solving a multi-index ST-FD equation through the Laplace transformation. For the first time, pressure distributions in cylindrical coordinates for heterogeneous fractured rocks with space- and time-dependent properties are presented. These findings are novel and unreported in existing literature, highlighting the utility of this approach in analyzing fractured reservoirs. The method developed in this paper was applied to five example well tests from fractured carbonate fields in northern Iraq, demonstrating the practical application of this methodology.

Two key models commonly used in the industry to study naturally fractured reservoirs are the Warren and Root (1963) dual-porosity model and de Swaan (1976) model. The Warren and Root model assumes a pseudosteady-state flow between the matrix and fractures, while de Swaan’s model addresses transient flow between these components. When applied to pressure buildup (BU) responses in fractured reservoirs from northern Iraq that exhibit a power-law pattern, these traditional models could lead to misinterpretations, attributing the behavior to boundary effects such as faults.

In contrast, using the continuous time random walk framework, specifically the ST-FD model developed by Raghavan and Chen (2021 and 2023), and now modified in this paper with solutions in Laplace space, provides a more accurate interpretation of these pressure responses. The analysis of real-world data using this modified ST-FD model reveals that the power-law behavior in pressure BU responses is linked to the reservoir’s complex heterogeneity as shown in five example well tests presented here. The effectiveness of the modified ST-FD model in Laplace space is validated, offering practical insights for well testing and accurate evaluations of reservoir recovery potential. Although the system is intricate at a fine scale, the results are applicable in the conventional sense at the Theis (1935) scale. Long-range connectivity and distorted flow paths that result in pauses, flow reversals, and related phenomena are quantified through three exponents and fractional derivatives.

The findings highlight the influence of diverse heterogeneity indexes and introduce an effective workflow for interpretation and reservoir assessment. These insights significantly enhance comprehension of the reservoir’s complex heterogeneity, leading to better estimations of ultimate recovery.

Purpose: Lactate Clearance (LC) has recently emerged as a therapeutic goal to be achieved in the first hours of septic shock’s resuscitation. In severe trauma patients, there is an urgent need to rapidly assess initial management’s quality and to diagnose occult hypoperfusion at its early stages. The aim of this study was to assess lactatemia and lactate clearance as predictors of mortality in severe trauma.
Methods: This was a retrospective, observational and analytical study. We included all adults having severe trauma and who required intensive care and who had a lactatemia measurement at admission (LH0), at the 4th hour (LH4), and the 12th hour (LH12). LC was calculated (%/h) between admission and the 4th hour (LC H0-H4), admission and the 12th hour (LC H0-H12) and the4th and the 12th hour (LC H4-H12). Our primary endpoint was in-hospital mortality. To assess the association of lactatemia and LC with mortality, we analyzed the ROC curves and carried out univariate and multivariate analysis in logistic regression.
Results: A total of 318 patients were included. LC H0-H12 (AUC = 0.753) was a better parameter than LH0 (AUC = 0.735), LH4 (AUC = 0.711), LH12 (AUC = 0.643), LC H0-H4 (AUC = 0.688), LC H4-H12 (AUC = 0.667) to predict in-hospital mortality. The cut-off was -2.92% with a sensitivity = 76.1% and a specificity = 63.6%. The in-hospital mortality rate increased from 21.3% for a negative LC H0-H12 to more than 50% for positive values. LC H0-H12 also performed better than RTS (AUC=0.724), MGAP (AUC=0.735) and ISS (AUC=0.729). The addition of LC H0-H12 and LH0 to these scores improved their quality as well as that of TRISS. Likewise, LC H0-H12 was able to predict early mortality (AUC=0.798), an ISS> 15 (AUC=0.602) and hemorrhagic shock (AUC=0.647). Finally, we could develop a clinical-biological prognostic score including LC H0-H12, pH, PT, Glasgow coma scale and age.
Conclusion: LC H0-H12 measurement is a relevant tool that should be incorporated into treatment regimens as part of a "Lactate clearance goal-directed therapy” in severe trauma.
Crustal Architecture and Isostatic Support in Zagros and Central Iran: Evidence from Seismic and Gravity Analysis
Authors: Sepahvand MohammadReza , Shishebori Mohammad , Nasrabadi Afsaneh
Published: January 2025

This study investigates the crustal structure and lithospheric dynamics of the Zagros Mountains and Central Iran using a joint inversion of receiver functions and Rayleigh wave phase velocity dispersion for 19 seismic stations. The results reveal significant spatial variations in Moho depth and crustal thickness, reflecting the tectonic complexity of the region. Crustal thickness gradually increases from eastern Iran (∼40 km) to Central Iran (∼42 km) and reaches its maximum beneath the Sanandaj-Sirjan Zone (SSZ, ∼58 km) and the Urumieh-Dokhtar Magmatic Assemblage (UDAM, ∼52 km). This thickening is attributed to the underthrusting of the Arabian Plate beneath Central Iran and crustal shortening associated with the Zagros orogeny. Low shear-wave velocities (Vs < 4.1 km/s) observed in the uppermost mantle beneath Central and Eastern Iran indicate variations in lithospheric composition and thermal structure. Correlations between crustal thickness, topography, and free-air gravity anomalies demonstrate the role of isostatic support and lithospheric flexure in shaping regional surface features. Positive gravity anomalies in the southern Zagros are linked to crustal underthrusting, while high-density rocks in the SSZ and UDAM contribute to short-wavelength gravity highs. These findings enhance our understanding of the geodynamic evolution of the Zagros and Central Iranian tectonic domains, highlighting their distinct geological histories and ongoing tectonic interactions.

Published: January 2025

Citrus indica Tanaka, a wild and endangered citrus species native to northeastern India, has been focus of surveys aimed at determining its distribution, studying its variability, and collecting its germplasm. Indian wild orange, this species is endemic to the region and was first collected from the Citrus Gene Sanctuary, located in the buffer zone of the Nokrek Biosphere Reserve in the Garo Hills of Meghalaya and has been observed in the Naga Hills of Nagaland. Additionally, a natural hybrid of C. indica was identified and collected for the first time from the South Garo Hills. Historically, C. indica had a wider distribution, with collections made from the states of Mizoram and Meghalaya. In Meghalaya’s Jaintia Hills, the natural populations of this species are now in a highly threatened state. The species is unevenly distributed across the surveyed areas. Morphological and biochemical analysis of its leaves, fruits, and seeds revealed significant variability among the collected specimens. Local knowledge of its uses and socio-economic importance suggests that this species has commercial potential in citrus industry. However, due to the lack of cultivation and the rapid deforestation in the region, urgent complementary conservation strategies are needed to protect the species and ensure its future availability. A focus on developing methods for propagation, multiplication, and regeneration in both in situ and ex situ conditions is critical.
Die Rolle des Autotaxins und der Einfluss von Lipiden auf die ROS-Entstehung in primären Maushepatozyten und hepatozellulären Zelllinien
Authors:   , Grimm Sabine
Published: January 2025

Autotaxin (ATX) ist ein 100-125 kDa großes, sezerniertes Enzym aus der Enzymfamilie der Ektonukleotid-Pyrophosphatasen/Phosphodiesterasen (ENPP2). ATX besitzt mit seiner zusätzlichen Lysophospholipase D-Aktivität die Fähigkeit, extrazelluläres Lysophosphatidylcholin (LPC) zu Lysophosphatidsäure (LPA) zu hydrolysieren. ATX beeinflusst als motilitätsstimulierender autokriner Faktor eine Vielzahl physiologischer Prozesse. Zu den diversen biologischen Funktionen von ATX/LPA zählen grundlegende Zellfunktionen wie z.B. Proliferation, Migration und Differenzierung.
Studien weisen darauf hin, dass ATX/LPA eine wichtige Rolle im oxidativen Status der Zelle spielt. Das Ziel dieser Promotionsarbeit war es, die Rolle von ATX/LPA bei der ROS-Produktion, die mittels Fettsäuren induziert wurde, zu untersuchen. Hierfür wurden transgene Mäuse mit einem Hepatozyten-spezifischen Knockout des ATX sowie HepG2-Zellen, die mittels Transfektion eine ATX-Überexpression aufwiesen, verwendet.
Die Untersuchungen bezüglich der Rolle von ATX/LPA in der ROS-Produktion deuten darauf hin, dass ATX/LPA einen maßgeblichen Einfluss auf die ROS-Produktion hat. Es wurde festgestellt, dass der Hepatozyten-spezifische Knockout von ATX zu einer höheren ROS-Produktion führt. Eine pharmakologische Hemmung von ATX in HepG2-Zellen führte ebenfalls zu höheren ROS-Werten. In HepG2-Zellen bewirkt LPA und eine ATX-Überexpression einen geringeren Anstieg der ROS-Werte.
Die in dieser Promotionsarbeit durchgeführten Experimente unterstützen die Hypothese, dass ATX/LPA Teil des ROS-protektiven Systems ist. Einige Medikamente wie Chemotherapeutika wirken durch die Induktion von oxidativem Stress. Die ROS-protektive Wirkung von ATX/LPA und die gute Verträglichkeit von ATX-Inhibitoren sprechen für die Möglichkeit eines additiven, klinischen Einsatzes von ATX-Inhibitoren. Auf Grund der Vielzahl an pleiotropen LPA-Rezeptoren und ihrer Beteiligung an verschiedenen Stoffwechselwegen sowie der Verwendung unterschiedlicher Zellsysteme und der verschiedenen Arten der ATX-Inhibition ist die Rolle von ATX/LPA in der NAFLD (Nicht-alkoholische Fettlebererkrankung) komplex und bedarf weiterer Untersuchungen.

Published: January 2025

Ukraine must search for efficient tools to accelerate the economic recovery in the post-war period. The workforce equipped with future skills is globally considered to be able to accelerate the pace of innovative growth and achieve the goals of Industry 4.0. This study aims to identify key skills of tomorrow and outline the ways in which these skills can be strengthened at Ukrainian universities. The skills of tomorrow that the Ukrainian standard for higher education recommends the universities include in the existing and new educational programs in various specialties were divided into five groups depending on their nature. Moreover, they were mapped following sustainable development goals to comprehensively assess their ability to promote each goal. Thus, the concept of a ‘future skill’ has been defined to contain aspects such as sustainability, skills, Industry 4.0, energy, education, energy efficiency, productivity, and creativity. The relationships between each future skill and its ability to facilitate sustainable development goals were described, and possible problematic areas were identified. Finally, the paper revealed that the skills able to boost the economy, which is specifically relevant for the post-war recovery of Ukraine, are not satisfactorily represented in Ukrainian higher education. Therefore, to make the Ukrainian higher education system a decisive factor in post-war recovery, it should shift the focus from solely hard skills to the skills of the future.
Application of The Argument Driven Inquiry (ADI) Model Using Interactive E-LKPD to Improve Students' Argumentation Skills
Authors: Wibowo Aldi Alfiansyah , Evi Roviati  , Novianti Muspiroh
Published: January 2025

Most students are not skilled in writing scientific arguments, have not expressed opinions accompanied by relevant data, learning uses teacher-centered discussion methods but is still not optimal, and teachers have never applied learning to improve students' argumentation skills. So, an alternative for improving students' argumentation skills is to use the Argument Inquiry (ADI) model, a recommendation for a 21st-century skills inquiry learning model that can improve students' argumentation skills. This research aims to analyze student activities in implementing the Argument-Driven Inquiry (ADI) model using Interactive E-LKPD, to analyze the increase in argumentation skills in students who apply the ADI model using Interactive E-LKPD and students who do not apply the ADI model using E-LKPD Interactive, and to analyze how students respond after learning by implementing the ADI model assisted by Interactive E-LKPD. This research was carried out at Al-Azhar 5 Cirebon Islamic High School. With a class X population, the samples are classes X.3 and X.1. Research on student activities during 3 meetings showed that the experimental class obtained the highest average score in the double-blind peer review syntax. The students' lowest activity during the learning process was the syntax for revising peer review reports. There is a significant difference in the increase in students' argumentation skills for the better after implementing the ADI learning model compared to students who did not apply the ADI learning model. The response of students who applied the ADI model assisted by Interactive E-LKPD showed a positive response
Large-scale clogging experiments assessing the hydraulic performance of porous asphalt during their service life
Authors: Goya-Heredia Angélica Vanessa , Naves Juan , Suárez Joaquín , Anta Jose
Published: January 2025

This study investigates the long-term behaviour of porous asphalt (PA) that retrofitted a 36 m2 laboratory full-scale street section, focusing on filtration and clogging processes. Throughout 11 experiments with increasing accumulative sediment loads up to 5.5 kg/m2, the evolution of surface permeability, water levels inside the asphalt, water flows, turbidity, and total suspended solid (TSS) concentrations were analysed. Sediment loads, representing dry-weather build-up, were applied to the asphalt surface, followed by simulated 30-min 80 mm/h rain events. Findings revealed an average permeability reduction rate of 4,717 mm/h per kg/m2. Surface clogging appeared from a cumulative load of 4.0 kg/m2, but the asphalt effectively managed rainfall with only marginal variations in flows and water levels, except for the vicinities of gully pots. The PA demonstrated a sediment retention efficiency of 93%, showing a significant decrease in turbidity and an increase in TSS concentrations once the asphalt became clogged. Comparison with the previous work emphasized the scalability and reliability of small-scale test results for analysing permeability evolution and retention efficiency, but such tests overlook real-world heterogeneities compromising the representativeness of water and sediment fluxes. The experimental dataset provides novel and valuable data for developing models to accurately simulate permeable pavements towards better urban planning, design, and maintenance.
Assessing impacts of climate crisis on water distribution systems though service inefficiency indicator
Authors: Borzì Iolanda
Published: January 2025

Climate change is significantly impacting water distribution systems worldwide, disrupting precipitation patterns and reducing freshwater availability. Sicily, Italy, is currently experiencing a severe water crisis due to drought and climate change, with depleted reservoirs affecting both agriculture and urban water supply. In March 2024, a state of emergency was declared, implementing water rationing for over 850,000 people across six provinces. This study focuses on Messina city's water scarcity challenges, proposing a Zonal Inefficiency Indicator (ZII) to assess the impact on the water distribution system, considering factors such as water distribution satisfaction, pressure regime issues, and network resilience. Using EPANET software, this study models various scenarios including pre-crisis conditions, current water scarcity, water rationing, and leakage reduction. Results demonstrate significant impacts of water scarcity on the network efficiency, with the ZII effectively quantifying these effects across different urban districts. While short-term water rationing shows limited improvement, leakage reduction emerges as the most effective long-term strategy for enhancing network efficiency. Conclusions recommend the prioritization of leakage detection and repair programs. These findings offer valuable insights for water managers in Messina and other regions facing similar challenges, supporting data-driven decision-making for sustainable water management in the face of climate change-induced water scarcity.
En las fronteras de la autoctonía. Migrantes internos e internacionales en Barcelona (España)
Authors: Mata-Codesal Diana , Aramburu Otazu Mikel
Published: January 2025

Este artículo explora las posibilidades heurísticas de tratar conjuntamente las migraciones internas e internacionales, algo descuidado por los estudios migratorios que han tendido a analizarlas por separado. Centrado en el caso de Barcelona desde 1960 hasta 2020, el estudio conjuga el análisis de fuentes secundarias y los trabajos de campo etnográfico realizados por los autores en dos barrios de la ciudad. Se muestra cómo ambos tipos de movilidades han sido “migrantizadas”, es decir, sujetas a una condición social distintiva que remite a los procesos de subalterización a los que estos grupos han sido sometidos en las sociedades de residencia. Si bien la generalización de los resultados a otros casos requiere mayor investigación, se aportan evidencias sólidas del carácter contingente de la categoría inmigrante y las posibilidades analíticas de explorar los procesos de fronterización —construcción, deconstrucción y reconstrucción de fronteras (boundaries)— que se generan en torno a la movilidad de poblaciones.

O bioma Caatinga ocorre nos estados do Maranhão, Piauí, Ceará, Rio Grande do Norte, Pernambuco, Paraíba, Alagoas, Sergipe, Bahia e Minas Gerais, no Brasil. Apesar de ser o único ecossistema exclusivamente brasileiro, poucos recursos para pesquisas sobre biodiversidade e conservação são voltados para este bioma. A geração de conhecimento sobre a diversidade biológica da Caatinga torna-se essencial para estabelecer estratégias eficazes de gestão e conservação de espécies e habitats, particularmente em um bioma tão sensível e ameaçado como esse. O presente trabalho se divide em dois capítulos e, o primeiro, consiste em uma extensa revisão bibliográfica sobre a ocorrência, distribuição e características cromossômicas das espécies de pequenos mamíferos terrestres que habitam a Caatinga. O segundo capítulo, apresenta dados sobre diversidade, ecologia e sazonalidade de uma comunidade de pequenos mamíferos terrestres (Didelphimorphia e Rodentia) através de um estudo usando o método de captura-marcação-recaptura ao longo de doze meses sucessivos de amostragem em um fragmento de mata nativa de Caatinga bem conservada situada na Fazenda Experimental Rafael Fernandes da Universidade Federal Rural do Semi-Árido, Mossoró-RN.

Os répteis são muito importantes para a manuntenção do meio ambiente, sendo considerados modelos para estudos biológicos por serem facilmente observados, manuseados e capturados. Tropidurus hispidus é a espécie de lagarto mais abundante em regiões de caatingas e ambientes secos, sendo muito comum no Brasil. Seu hábito alimentar é constituído principalmente por invertebrados, no entanto, podem ingerir partes de vegetais. Devido ao seu hábito alimentar diferenciado e a carência de informações relacionadas à morfologia desses animais, foi proposto um estudo da caracterização morfológica do trato digestório do Tropidurus hispidus. Foram utilizados 4 animais de ambos os sexos da espécie Tropidurus hispidus da região de Apodi-RN. Faz-se necessário um estudo aprofundado para coletar mais dados desta correlação, para que se tenha um melhor entendimento do sistema digestório do Tropidurus hispidus. Portanto, o objetivo do presente trabalho é descrever a caracterização morfológica do trato digestório do Tropidurus hispidus. Os animais foram anestesiados e eutanaziados. O trato digestório foi dissecado, fixado em Metacarn e incluídos em parafina. Foram feitos cortes de 5 μm de espessura foram corados com H&E, tricromo de Gomori, tricromo de Mallory e azul de alcian. O sistema digestório do Tropidurus hispidus possui uma língua com estrutura cartilaginosa tanto na sua parte central como nas laterais, o epitélio do esôfago é do tipo pseudoestratificado ciliado com células caliciformes, o estômago apresentou a camada muscular é bem desenvolvida tanto na parte inicial como na parte final, o intestino delgado é mais longo que o intestino grosso, porém camadas que formam o intestino grosso têm características semelhantes às do intestino delgado. O fígado apresentou células melanomacrofagos e pâncreas não apresenta ilhotas de Langerhans, todas essas diferenças podem estar principalmente relacionado com o hábito alimentar desses animais.

Os queijos artesanais participam da identidade sociocultural do povo e merecem valorização. Como muitos queijos produzidos de forma artesanal, é comum a fabricação dos queijos de coalho e de manteiga com leite cru. Por isso, é fundamental que a matéria-prima das queijarias apresente boa qualidade, a fim de minimizar riscos aos consumidores. Dessa forma, objetivou-se avaliar a qualidade do leite em queijarias artesanais do Rio Grande do Norte, Brasil. Foram coletadas cinquenta amostras de leite de nove queijarias informais de regiões que se destacam como bacias leiteiras no Estado. As amostras foram submetidas às análises microbiológicas (microrganismos mesófilos estritos e facultativos viáveis, coliformes totais, termotolerantes, Salmonella spp. e Staphylococcus aureus), físico-químicas (acidez titulável em graus Dornic, densidade, índice crioscópico, estabilidade ao alizarol, porcentagens de proteína, lactose e gordura), residuais e pesquisa de fraudes recorrentes em leite. Todas as amostras ultrapassaram o limite estabelecido pela legislação para contagem de microrganismos mesófilos; houve presença de Salmonella spp. em uma amostra. Dada esta contaminação, a acidez de 76% das amostras estava acima do permitido pela legislação. Quanto aos parâmetros de gordura e proteína, 14% e 10% das amostras estavam abaixo dos valores exigidos pela legislação, respectivamente. Além disso, houve fraude por adição de água em 24% das amostras. Foram encontrados cloretos em 16% e resíduos de antimicrobianos em 46% das amostras. Portanto, a qualidade do leite usado na fabricação informal de queijo artesanal no estado do Rio Grande do Norte é pobre, podendo representar um risco para o consumidor, com o comprometimento da qualidade dos queijos de coalho e de manteiga.
Soroprevalência e caracterização genética de estirpes de campo do vírus da anemia infecciosa equina em equídeos errantes do estado do Rio Grande do Norte

Published: January 2025

A anemia infecciosa equina (AIE) é a doença infecciosa de etiologia viral
mais importante entre os equinos. É uma doença endêmica em populações de equídeos
por todo o mundo. Considera-se que todos os equídeos são susceptíveis embora os
trabalhos publicados se concentrem em equinos, sendo escassas as informações sobre
AIE em asininos. No Rio Grande do Norte (RN) milhares de asininos vivem livres,
constituindo um problema para o controle de enfermidades como a AIE, pois podem ser
prováveis reservatórios e fontes de transmissão delas. Neste trabalho, amostras de 409
animais (asininos e equinos) foram submetidas aos testes de IDGA, ELISA pgp45 e
nested-PCR, utilizando iniciadores para o gene gag e LTR. Quatro amostras (0,98%)
foram positivas em pelo menos um teste sorológico, e dessas, três amostras (0,73%)
foram positivas na nested-PCR. Não obtivemos material suficiente para sequenciamento
das amostras de LTR dos asininos sendo sequenciado apenas o amplificado de LTR
referente à amostra do equino positivo. O alinhamento (BLAST) permitiu a
identificação da sequência como vírus da AIE (EIAV) com 95% de similaridade de
nucleotídeos com estirpes europeias. Os três produtos obtidos da nested-PCR para o
gene gag foram sequenciados e submetidos à análise filogenética. O resultado da análise
sugeriu que a sequência obtida do cavalo confirmaram a identificação como EIAV, com
a mesma origem de isolados da América do Norte, e que as sequencias de asininos não
possuem identidade com nenhuma outra deo EIAV até o momento publicada. Desta
forma, estudos adicionais são necessários para confirmar se, com estes resultados, foram
identificados um lentivirus ainda não descrito que infecta Equus asinus (e qual papel
ele teria para outros equídeos) ou se trata de retrovírus endógenos que expressa
proteínas usadas como marcadores de diagnóstico da AIE. Embora os dados
apresentados sejam incipientes, revelam um cenário interessante para o estudo das
lentiviroses em asininos.
Fogászati implantátumok felületkezelési eljárásainak összehasonlító vizsgálata

Nowadays, the most common type of implant in dentistry is a partial tooth replacement, such as a crown, or a complete tooth replacement. Today, many manufacturers offer implants made of a wide variety of materials and designs. These restorations must meet strict standards, one of the most stringent being surface roughness. Since proper bone-to-implant contact only occurs with adequate surface roughness, several methods are used to achieve the correct value. After reviewing the results of experiments carried out by several research groups, it is concluded that the surface roughness, the shape of the implant fixation screw, the shape of the thread and the thread elevation used to achieve the desired roughness together determine the success of the implantation. The average surface roughness required for osseointegration is considered to be optimal for values between 1 and 100 µm. In most cases, the surface roughness of commercially available dental prostheses is Ra 1-2 µm, but this can be modified by various grinding, acid etching and polishing processes to suit the application. Acid etching is a common technique for roughness reduction, which is the most effective in reducing surface roughness of dental restorative materials (mostly titanium alloys), thus bringing the roughness within the desired range. The result of acid etching is influenced by the concentration of acid, the temperature of the acid bath and the time spent in the acid. The acid used for the surface treatment is important and is most commonly sulphuric acid, hydrochloric acid or hydrogen fluoride (HF) and combinations of these. The study shows that the most optimal results are obtained with HF. Replacements are nowadays largely made by additive manufacturing, which allows for customised replacements and, due to dimensional accuracy, reduces the time and cost of post-processing, i.e. the surface treatment can be used to achieve the desired surface roughness and size at the same time. As a result, newer materials are being used for clinical prostheses and surface treatment should be applicable to all materials. The most optimal solution is a combination of grit blasting and acid etching. With this technology, the surface roughness for all materials reaches the optimum value of 1-100 µm, sometimes 1-2 µm, but can be further reduced below 1 µm by polishing. The study investigates the role of surface roughness, the surface roughness should only be reduced up to a certain value, approximately 0.5 µm, as smooth surfaces have limited or no potential for osseointegration.

The intersection of agriculture and cybersecurity has become a prominent research focus in recent years, driven by the rapid adoption of IoT (Internet of Things) and precision farming technologies. These technological innovations have revolutionized agricultural processes, enhancing efficiency and sustainability while introducing significant security risks. This study conducts a systematic literature review (SLR) to address key cybersecurity issues in agriculture, with a particular emphasis on IoT vulnerabilities and threats. Using Python-based text analysis techniques, the research automated the analysis of abstracts and full texts, enabling rapid filtering and thematic categorization of relevant studies. From an initial pool of 1,039 publications, 40 relevant studies were identified based on rigorous screening criteria. The thematic analysis revealed that 44.9% of the publications focus on IoT device vulnerabilities, 32.7% on agricultural cybersecurity challenges, and 22.4% on the security issues of Agriculture 4.0 and precision farming. Methodological analysis indicated that machine learning, simulation models, and case studies dominate the research landscape, while surveys and experimental studies appear less frequently. The findings highlight the critical importance of developing robust cybersecurity strategies and technologies in the agricultural sector, particularly to mitigate the risks posed by IoT devices.
