Application of acupuncture combined with ultrasound-guided thoracic paravertebral nerve block in thoracoscopic surgery for lung cancer: A Randomised Controlled Trial
Authors: Ding Longfei , Xu Xuan , Liu Jie , Wang Beiru , Wu Caineng
Published: December 2024

Background
Patients undergoing thoracoscopic lung cancer surgery often undergo ultrasound-guided thoracic paravertebral block before surgery, but adverse effects such as hypotension and bradycardia often occur after the block. The purpose of this study is to evaluate the hypothesis that electroacupuncture is effective in treating hypotension and bradycardia after ultrasound-guided thoracic paravertebral block.
METHODS
Adult patients scheduled to undergo thoracoscopic lung cancer surgery were randomly assigned to the electroacupuncture group and the control group after undergoing ultrasound-guided thoracic paravertebral block. In the intervention group, electroacupuncture treatment was started at the Neiguan (PC6) and the Zu Sanli (ST36) acupoints 30 minutes before the procedure and continued until the end. Patients in the control group received the same electroacupuncture treatment at non-acupuncture points (near PC6 and ST36). The primary outcome of this trial was the incidence of hypotension after thoracic paraspinal block.
Results
The incidence of hypotension after ultrasound-guided thoracic paravertebral block was lower in the EA group compared to the control group: 22(56.4%) vs 7(17.9%), P < 0.01. The incidence of bradycardia in the EA group was also reduced: 12(30.8%) vs 3(7.7%), P = 0.01.
Conclusions
Perioperative EA treatment can effectively reduce the incidence of hypotension and bradycardia after ultrasound-guided thoracic paravertebral block in patients undergoing thoracoscopic lung cancer surgery.

Purpose
This study analyzes the demographic information, concurrent infectious diseases, treatment methods, and hospitalization costs for children with transient synovitis of the hip (TSH) in China and to provide a scientific basis for its early diagnosis, treatment decisions, and preventive measures.
Methods
We retrospectively analyzed the data of children with TSH who were hospitalized across 32 pediatric tertiary hospitals affiliated with China’s Futang Research Center of Pediatric Development between December 1, 2015, and December 31, 2022. We used the ICD10 codes on the first page of the medical records to identify the cases and extracted data on age, sex, diagnosis, concurrent infectious diseases, treatment methods, season of treatment, region, and various expenses incurred during hospitalization.
Results
The study cohort comprised a total of 5065 children, including 3711 males and 1354 females. The age group with the highest number of TSH cases was the preschool children group, with 2452 cases (48.4%), and the lowest number of cases was recorded in the adolescent group, with 119 cases (2.3%). In terms of hospitalization time, the adolescent group had the longest average hospitalization time of 9.4 ± 5.6 days. In terms of the distribution of onset time, the largest proportion of TSH cases was recorded in winter (26.52%), and the smallest proportion, in spring (23.06%). In terms of the geographical distribution of onset, the number of cases in East China was higher than that in other geographical regions. In addition, among the 5065 children included, 16.7% had infectious diseases, of which respiratory tract infections accounted for the largest proportion (92.6%), followed by gastrointestinal infections (3.0%). In terms of treatment options, children were more likely to receive conservative treatment (7,667 instances) than surgical treatment (80 instances). Among conservative treatments, the most common was skin traction (4,508 instances). Among the various hospitalization expenses, the cost of examinations was the highest, reaching RMB 1,312(Renminbi, China's official currency).
Conclusion
This study provides important clinical data supporting the epidemiological characteristics and treatment of children with TSH in China and provides a scientific basis for strengthening the prevention, diagnosis, management, and treatment of the disease that could help reduce the public health burden posed by TSH and optimize the treatment process.
Research on luminaire paint defect detection model based on improved YOLOv10
Authors: Wu Dengtao , Yang Likang
Published: December 2024

Aiming at the problems of low detection accuracy, low computational efficiency and poor detection ability of multi-scale targets in existing detection methods, an improved YOLOv10 algorithm was proposed to improve the accuracy and efficiency of multi-scale defect detection of luminaire paint. By introducing the LSKA attention mechanism to the SPPF module on the YOLOv10 feature extraction backbone network, the recognition ability of the complex form of paint defects of lamps is improved. At the same time, the lightweight design of C2f and detection head module makes the algorithm more suitable for real-time application scenarios. In terms of evaluation indexes, after ablation experiments, the improved algorithm has improved 2.6% compared with the original YOLOv10 in main performance indexes mAP@0.5. In addition, the lightweight design of the improved algorithm significantly reduces the number of parameters and the amount of computation required. Compared with the original YOLOv10, the number of parameters is reduced by 0.22×106 and the amount of computation is reduced by 1.4GFLOPS, making it more suitable for deployment in resource-constrained environments. The improved YOLOv10 algorithm proposed in this paper achieves a balance of high accuracy and high efficiency in the multi-scale defect detection of luminaire paint surface, providing a reliable machine learning technical means for industrial production, and helping industrial equipment to carry out efficient monitoring and diagnosis under unattended conditions.
Treatment Failure in Non-Intubated Acute Respiratory Distress Syndrome: A Retrospective Cohort Study
Authors: Kim Kyung Hoon , Yoon Joo Heung , Kim Seok Chan , Lee Jongmin
Published: December 2024

Background
Acute respiratory distress syndrome (ARDS) is a severe respiratory condition associated with high mortality, traditionally requiring invasive mechanical ventilation. However, the recent global redefinition of ARDS now encompasses non-intubated patients receiving high-flow nasal oxygen (HFNO) or non-invasive positive pressure ventilation (NIPPV), emphasizing the need for non-invasive management strategies. Despite their widespread use, the factors contributing to treatment failure in these modalities remain poorly understood. The aim of this study was to analyse the characteristics related to the treatment failure of HFNO and NIPPV in patients who met the new global definition of non-intubated ARDS.
Methods
Patients who satisfied the newly defined criteria for non-intubated ARDS receiving HFNO or NIPPV were included in the MIMIC-IV database. Clinical characteristics and parameters were analysed, including respiratory rate–oxygenation (ROX) value at 1, 6, and 12 h after applying HFNO or NIPPV. Of the 238 patients, 114 and 124 received HFNO and NIPPV, respectively.
Results
In the HFNO group, the ROX value 1 h after application was significantly lower in patients with treatment failure (AUROC 0.702, cut-off value 4.059). In the NIPPV group, the ROX values at 1, 6, and 12 h were significantly lower in patients with treatment failure. However, only that at 12 h was consistent (AUROC 0.696, cut-off 7.827) after adjusting for confounders. The ROX index demonstrated its utility in predicting treatment failure in non-intubated ARDS, with the timing of assessment varying based on the respiratory support modality. For HFNO, the ROX index at 1 h was the most predictive, whereas, for NIPPV, the ROX index at 12 h showed the strongest association with treatment failure.
Conclusions
These findings underscore the importance of tailored monitoring strategies based on the type of respiratory support provided.
Mandatory verses voluntary self-tests for new online casino customers – effect on engagement, quality, gambling behavior and use of responsible gambling measures.
Authors: Jonsson Jakob , Lakew Nathan , Lindner Philip
Published: December 2024

Background: To combat the public health concern that is problem gambling, gambling operators are increasingly being required by legislation to exercise a duty of care obligation, including the provision of Responsible Gambling (RG) tools. Self-test assessments have long been a popular RG tool implemented by many operators, yet there has been scant empirical research on self-tests, including on how the method of delivery impacts engagement, quality, and subsequent gambling behavior. The main objective of the current study was to examine if the level of voluntariness to perform a self-test moderated these key outcomes.
Method. Participants in the study, 1,800 new online customers at a leading Swedish gambling company, were randomized to one of three arms: No message (control), up to four messages inviting them to do a self-test, and one message with a mandatory (but technically possible to circumvent) self-test. The interventions were presented when the customer logged in.
Results: The results showed that 38.9% in the mandatory group and 4.8% in the voluntary group completed the self-test, with indications of a somewhat lower quality of the test by the mandatory group. There was no difference in customer churn or gambling behavior, and only minor differences in use of RG-measures post intervention.
Conclusions. We conclude that presentation format matters and can affect the use and quality of tests:gambling operators should exercise caution when interpreting non-risk assessment results derived solely from self-test tools, particularly mandatory ones, as it can result in inaccurate risk assessments that may mislead duty of care obligations. The balance between achieving high participation and maintaining quality (and thereby meaningfulness) is discussed.

Published: December 2024

Robotic intracorporeal single-stapled anastomosis (RiSSA) is an innovative technique in robotic low anterior resection with total mesorectal excision (LAR-TME), though its outcomes remain underreported, particularly among Asian rectal cancer patients. This study retrospectively evaluated early clinical outcomes of RiSSA in robotic LAR-TME performed at a tertiary medical center in Kaohsiung, Taiwan. A total of 22 rectal cancer patients undergoing robotic LAR-TME with RiSSA between May 2023 and September 2024 were reviewed. Demographic and tumor-related factors such as age, gender, BMI, tumor size, and location were analyzed, along with key surgical and postoperative outcomes including blood loss, operative time, complications, mortality, length of hospital stay, ICU admissions, readmissions, and reoperations. The median patient age was 60.4 years. 72.7% of the patients were male. Median BMI and tumor size were 23.0 kg/m² and 3.6 cm, respectively. 68.2% of the tumors were in the mid or lower rectum. The median console time was 186.5 minutes. The median intraoperative estimated blood loss was 40 mL. No mortality or anastomotic leakage occurred. The median hospital stay was 7 days, with only three minor complications (Clavien-Dindo I-II) reported, including wound infections and chyle leakage. No unplanned ICU admissions, readmissions, or reoperations occurred. These findings suggest that RiSSA during robotic LAR-TME is a safe and feasible alternative to conventional double-stapled anastomosis methods, demonstrating favorable short-term outcomes with minimal complications. Further large-scale studies are warranted to validate its long-term safety and clinical effectiveness.

Published: December 2024

Background
Vonoprazan and amoxicillin dual therapy (Vo-Amx) has shown promising results on H. pylori eradication. However, its efficacy needs to be verified in this both H. pylori and gastric cancer prevalent area, and it is also unknown if the modified Vo-Amx plus bismuth (Vo-Amx-Bis) regimen might increase its efficacy. We aimed to investigate the efficacy and safety of Vo-Amx and Vo-Amx-Bis regimens, and if the Vo-Amx-Bis regimen might be superior to Vo-Amx and bismuth-containing quadruple therapy (BQT) therapy for H. pylori eradication, as well as factors that affect the curing rate.
Methods
A total of 342 treatment-naïve H. pylori-infected patients were screened and 210 were enrolled and randomized into Vo-Amx, Vo-Amx-Bis, and BQT groups for treatment. H. pylori infection status was determined by 13C-urea breath test. The eradication rate and incidence of adverse events were assessed, and factors that might affect the curing rate were also analyzed.
Results
In per-protocol (PP) analysis, H. pylori eradication rates in Vo-Amx, Vo-Amx-Bis, and BQT groups were 95.1%, 92.3%, and 90.4%, respectively (p > 0.05). In intention-to-treat (ITT) analysis, eradication rates in Vo-Amx, Vo-Amx-Bis, and BQT groups were 91.8%, 90%, and 88.2%, respectively (p > 0.05). The eradication efficacy of Vo-Amx and Vo-Amx-Bis groups was non-inferior to that of BQT group, and the incidence of side effects (including nausea, vomiting, anorexia, abdominal pain, diarrhea, palpitation, dizziness, and debilitation) was lower than that of BQT group (6.1% and 5.1%, vs 45.8%, respectively, p < 0.001). Successful eradication was associated with lower body surface area (BSA) in BQT group (p < 0.05), but not in Vo-Amx and Vo-Amx-Bis groups. Gender, cigarette smoking, alcohol drinking, side effects, education level, body mass index (BMI), infection status of family members, and the frequency of dining out did not affect the curing rate in all three groups (p > 0.05).
Conclusion
Efficacy of the two vonoprazan-containing regimens was comparable and non-inferior to the bismuth-based quadruple therapy in this region, and could serve as the first-line regimen for H. pylori eradication, and reduced use of one antibiotic per each patient treatment in real-world clinical application.

Published: December 2024

Multiple sectors, including agriculture and construction, have produced large amounts of waste in recent years, leading to significant environmental problems. The construction sector is currently faced with the severe difficulties of decreasing natural resources and a growing dependence on waste management, highlighting the need for quick action for an approach to recycling and the introduction of alternative materials. The study concentrates on recycling waste materials and developing innovative construction products. This includes replacing 20% of cement with limestone powder and rice husk, replacing 50% of fine aggregates with construction and demolition waste, and incorporating 1% coconut fiber. The evaluation of these materials involved conducting tests to assess compressive strength, split tensile strength, and flexural strength using cube, cylinder, and beam samples parallel to water absorption and non-distractive tests. The methods in machine learning, including Response Surface Methodology, were utilized for prediction, showing enhanced hardened properties. This study suggests that incorporating waste materials into construction practices can protect natural resources and provide sustainable options for the future.

Authors: K Manojkumar , L Suji Helen
Published: December 2024

The crowd emotion sensing is a critical element in surveillance and management of the crowd in different environments. With exploding populations, and developing nations, the crowd in urban cities mandate state of art surveillance methodologies involving continuous monitoring and reporting of criminal activities. The research article presents a novel technique to compute the spatial and temporal features obtained from the crowd environments and combine the novelty of neural networks for detecting the emotions of crowds with better accuracy and swiftness. The features are obtained from the continuous feed of surveillance videos typically categorized into the common features of human beings namely anger, sadness, disgust, surprise, fear, happiness and obviously neutrality. Such features are extracted after careful background separation which are typically difficult in crowded environments, using techniques namely SIFT, and FAST termed to be the visual descriptors. Once the features are extracted, spatial and temporal features are classified into individual and combined features as defined in the cross-division environment in order to portray the crowd dynamics and characteristics. Cross division environment computes the necessary features for identifying the anomalies in the crowded situations in a neural network, after a series of operations such as dimensionality reduction, and principal component analysis. From the semantic information, crowd behaviours are detected based on interactive features in a dynamic environment and the proposed technique has demonstrated effective results in terms of 98.9% accuracy in detecting especially violence in crowd datasets collected from UMN.

La tuberculose (TB) est une maladie infectieuse a transmission interhumaine liee au bacille de koch (BK) qui constitue toujours un probleme de sante publique majeur dans le monde et au MAROC. Le Quantiferon-TB Gold plus (QTF-plus) comme test de la liberation dInterferon Gamma (IFNÃŽÂ³) comporte deux valeurs TB1 et TB2 qui permettrait en plus de lorientation vers le diagnostic de tuberculose, de differencier entre TB latente et active. Ce travail a pour objectif devaluer la valeur diagnostic du dosage de QTF-Plus en matiere de Tuberculose active (TBA), et sa capacite a differencier tuberculose active et latent. Une etude transversale a ete realisee dans ce cadre, setalant sur 2 ans, chez Quarante-sept (47) patients hospitalises suspects de tuberculose evolutive recrutes (29 hommes / 18 femmes), lage moyen est de 43,2 ans. Les patients ont ete explores sur les plans clinique, radiologique, biologique bacteriologique avec realisation du QTF-Plus. Une TBA probable a ete diagnostique chez 32 patients (68,1%), alors que 15 malades (31,9 %) ne presentent pas de TM. Le QTF-Plus est positif dans 74,5 % des cas, negatif dans 25,5%. La Sensibilite (Se) du QTF-Plus dans notre serie est de 96,88 %, sa specificite Specificite (Sp) est de 73,33 %, la VPP est a 88,57 % et la VPN a 91,67 %. Selon le resultat de notre serie qui reste limite, et suite au calcul des differents seuils de positivite des valeurs du QTF-Plus on peut conclure que :- Chez un malade suspect de presenter une TB active, sur des arguments cliniques et radiologiques, la valeur la plus elevee de TB1 et TB2 inferieure a 0.11 UI/mL permettrait deliminer une tuberculose. (La Se seleve a 100% et la VPN a 100%) - Alors quune reponse TCD8 estimee par la valeur de TB2-TB1 superieur a 0.5UI/mL associee a une valeur la plus elevee de TB1 et TB2 superieure a 2,3 UI/mL permettrait de consolider le diagnostic de TB evolutive.

IgD multiple myeloma is a rare and aggressive form of multiple myeloma, constituting only about 2% of cases. The disease is often diagnosed at an advanced stage due to its nonspecific symptoms, which include bone pain, renal failure, and hypercalcemia. We report a case of a 74-year-old male patient diagnosed with IgD myeloma at the Military Hospital of Mohamed V in Rabat. His diagnosis was confirmed through electrophoresis, immunofixation, and bone marrow biopsy, revealing monoclonal IgD and significant plasmacytic infiltration. This case highlights the challenges in diagnosing IgD myeloma, especially in elderly patients, and emphasizes the need for advanced diagnostic techniques. Despite its rarity, IgD myeloma remains a challenging and poor-prognosis condition, often resistant to standard treatments. Early detection and a multidisciplinary approach are key to managing this disease.

Viper bites represent a critical medical emergency, particularly in rural areas or military contexts where rapid access to care may be limited. These envenomations can lead to severe and potentially fatal complications, including local effects (tissue necrosis, compartment syndrome) and systemic effects (disseminated intravascular coagulation (DIC), acute kidney injury (AKI), and shock). This article reports the case of a 29-year-old man who sustained a viper bite on his right hand. The envenomation rapidly progressed to compartment syndrome, severe DIC, and AKI, necessitating intensive multidisciplinary management. Prompt administration of antivenom, followed by urgent surgical interventions (fasciotomy and necrosectomies) and intensive management of hematological and renal complications, resulted in a favorable outcome. This case highlights the importance of a rapid and coordinated approach in the treatment of severe envenomations.
How does global economic policy uncertainty affect Islamic bank performance? An exploration from heterogeneous sample
Authors: Zuhroh Idah , Rofik Mochamad
Published: December 2024

This study investigates the impact of Global Economic Policy Uncertainty (GEPU) on the performance of Islamic banking, as measured by Non-Performing Financing (NPF) and Return on Assets (ROA). Utilizing quarterly data from 2014 to 2022 across three countries – Indonesia, Nigeria, and the UAE – and employing the Autoregressive Distributed Lag (ARDL) model with a Mean Group (MG) estimator, the findings indicate that GEPU does not significantly impact NPF in either the short or long term. In the short term, GEPU has the potential to reduce ROA; however, in the long term, it positively influences the profitability of Islamic banks. Specifically, in Indonesia, the results suggest an initial increase in NPF and a decrease in ROA in the short term. Conversely, in the long term, this trend reverses, with NPF declining and ROA increasing. In Nigeria, although GEPU may elevate NPF in the short term, this negative effect dissipates over time, with profitability remaining unaffected in both timeframes. In the UAE, NPF is stable in the short term, but there are indications of a long-term increase in NPF, while profitability remains stable across both short and long terms.

New Petroglyphs of Eastern Sayan Highlands as Part of Central Siberian Rock Art
Authors: Zaika Alexandr L.
Published: December 2024

The article describes the rock carvings discovered during the winter expedition of 2024 on the Kan River in the highlands of the Eastern Sayan Mountains. The colorful images of animals, people, and symbols were preliminarily attributed to the Early Bronze Age or the period between the Early Iron Age and the Early Middle Ages. They reflect a symbiosis of various pictorial traditions in depicting scenes of cattle breeding and hunting. The Early Bronze Age images include a mask with teardrop-shaped eyes and a bull in the Minusinsk style, as well as an anthropomorphic figure of the Tas-Khaza type. They belong to the Okunev culture and mark the migration from the steppes to the east that happened 4,000 years ago. The more recent images follow the traditional regional rock art themes, but their style and iconography are more typical of the neighboring territories, e.g., the Middle Yenisei or the Lower Angara. The rock art of the Upper Кan River area marks the ancient communications and ethno-cultural ties between different regions of Siberia. The main trajectories of intercultural contacts went through the eastern tributaries of the Yenisei and the left tributaries of the Angara, as well as across the radial network of the Sayan Mountains. The Eastern Sayan highlands remain understudied as an ancient intercultural hub and require further archaeological research.

In the current geopolitical situation, the Russian Federation needs a scientifically optimal strategy to achieve a technological sovereignty, which has become a factor of national security. This research relied on newly-declassified archival documents that describe governmental decisions made in the second half of the 1960s on the Ryad computer complex. The research objective was to explain the technological backwardness of the USSR in the field of computer technology. The theory of modernization made it possible to conclude that the Ryad project was slowed down due to poor technical documentation, element base, mathematical support, and allocations, not to mention the insufficient production facilities and slow construction. The project turned out to be much less effective than expected and failed to bridge the technological gap. The Soviet authorities chose to copy American samples at the expense of the domestic R&D. As a result, Soviet computing centers accumulated computers that were based on borrowed technologies, and the domestic computer manufacturing never became a catalyst for structural adjustment. It happened as a result of poor planning and management, as well as the priorities of the contemporary economic policy. The defense and civil sectors had no proper interaction while the immediate interests of ministries dominated over long-term prospects. Soviet enterprises did not invest in modernization, and the government ignored the recommendations of leading scientists.

The article describes the policy on Afghanistan conducted by Germany during its temporary membership in the UN Security Council in 1995–1996. As a permanent member of the Security Council, the Russian Federation was responsible for global peace and security, Sergei V. Lavrov being the Russian ambassador to the UN during the period under consideration. Based on archival and previously unpublished documents, the authors identified the key parameters, characteristics, and trends of the Afghan vector in Germany’s policy in the UN system. They relied on the principles of historicism and objectivity, as well as on Clive Archer’s role concept of international organizations. Germany’s activities in the Security Council revealed the duality of its foreign policy regarding the conflict in Afghanistan. After several decades of post-war diplomatic efforts to regain political influence, Germany opposed the crucial role of the Security Council on the Afghan issue. It focused on the General Assembly in an attempt to support Norbert Hall, who was the German Special Envoy in Afghanistan and the Head of the UNSMA mission, which was initiated by the UN General Assembly. As a result, Germany tried to minimize the role of the Security Council in Afghanistan in favor of the General Assembly.

Mineral content in bambara nutshell (BNS) can act as active sites for catalysis, while the protein content can be carbonized to produce support structures for the catalyst. BNS char based solid acid catalyst is produced in this study for biodiesel (FAME) production, using oleic acid esterified with methanol. The objective of the study is to determine the order of reaction ran at 50-65 for 180 min utilizing the integral kinetic rate expression. It also involves analyzing the rate constants obtained, so as to use it to estimate the activation energy () and pre-exponential factors () necessary to describe the mechanism of the reaction. Findings show that, the presence of -OH functional group in BNS makes it a good candidate for biodiesel production. Faster reaction and conversion to FAME product ( 52%) occurred at 65. The first-order model almost describes the experimental data at 60 and R2 = 0.9850, only that it has an intercept, which is not typical of the model; although not a sufficient reason to discard it. In this study, the best model fitted is second-order at the lowest temperature analyzed (i.e., 50 with rate constant,  = 2 L/mol.min L/mol.min), due to faster reaction rate described by its higher  value of 6.973 L/mol.min. However, the first-order rate’s low energy requirement ( 51.63 kJ/mol), was the reason for its sluggishness compared to second-order  65.17 kJ/mol; which explains the reason why the choice of the best model could go both ways, if energy efficiency is considered. Despite the performance of the oleic acid, which is favorably described by the first- and second-order rate, its conversion to biodiesel is moderately significant.

A energia eólica obtém destaque no cenário nacional como fonte renovável a partir de uma significativa cooperação na matriz energética brasileira da última década. No que tange ao processo de planejamento energético, o Plano Nacional de Energia (PNE 2050), publicado em 2020, urge como uma iniciativa capaz de definir as trajetórias e metas para a transformação do setor energético brasileiro, o que inclui os cenários de demanda, suprimento e contribuição financeira proporcionados pela geração de energia através dos ventos. Nesse contexto, busca-se analisar as transformações ocorridas no primeiro triênio após a publicação do Plano no setor eólico brasileiro. Para isso, a metodologia utilizada foi a quali-quantitativa, com base em dados oficiais, políticas públicas atuais, doutrina especializada e documentos técnicos publicados pelos órgãos oficiais do setor regulatório energético do Brasil. Com esse fundamento, este trabalho explora os cenários que envolvem a energia eólica no país no período de 2021 a 2023. O desenvolvimento da contribuição de fontes eólicas encontra-se em um contexto positivo, com crescimento percentual maior que o esperado, e os incrementos anuais foram destaques com os maiores percentuais de variação, ainda que a oficialização de marcos regulatórios e desafios necessitem de subsídios nas próximas décadas.

Published: December 2024

Os combustíveis sintéticos têm ganhado destaque como alternativa promissora para a transição energética global. No entanto, os altos custos de produção, a necessidade de avanços técnicos para melhorar a eficiência, e a falta de políticas governamentais e incentivos de apoio, além de barreiras regulatórias, dificultam a implementação desses combustíveis. No Brasil, avanços regulatórios como o Marco Legal do Hidrogênio Verde começam a surgir, abrindo caminho para que o país desenvolva políticas públicas que favoreçam tecnologias de combustíveis sintéticos e promovendo a diversificação da matriz energética. Dessa forma, este artigo apresenta uma revisão dos avanços normativos e de políticas relacionadas ao desenvolvimento e implementação de tecnologias sustentáveis no Brasil, com foco em três áreas: hidrogênio verde, combustíveis sintéticos e captura de carbono. Foram analisadas iniciativas governamentais, políticas estaduais, incentivos financeiros, apoio à pesquisa, padronização e certificação do hidrogênio verde, normas e incentivos para combustíveis sintéticos, além de aspectos regulatórios da captura de carbono. Por serem temas relativamente novos no Brasil, o artigo aborda as iniciativas já em curso para viabilizar o desenvolvimento dessas tecnologias no país. Além disso, são apresentados exemplos de regulamentações e políticas adotadas em outros países.

A captura de carbono surge como uma estratégia crucial para mitigar as mudanças climáticas, equilibrando o desenvolvimento econômico e a preservação ambiental. Com foco na redução das emissões de gases de efeito estufa (GEE), existem tecnologias voltadas à captura de dióxido de carbono (CO2) de fontes emissoras antes de sua liberação na atmosfera, possibilitando seu armazenamento em formações geológicas ou sua reutilização na produção de produtos de alto valor, como os combustíveis sintéticos. Aliada às políticas climáticas internacionais, como o Acordo de Paris, e ao mercado de carbono, a captura de carbono complementa fontes renováveis e promove a inovação tecnológica. Apesar dos desafios técnicos e econômicos, sua aplicação é essencial para uma transição energética sustentável, reforçando a descarbonização e contribuindo para o enfrentamento das mudanças climáticas. Este estudo apresenta uma análise abrangente das tecnologias de captura, utilização e armazenamento de carbono (CCUS, Carbon Capture, Utilization and Storage), abordando seu potencial, limitações e papel na transição para uma economia de baixo carbono.
Catalisadores para síntese de amônia: revisão e desafios para a produção sustentável
Authors: Faria Duarte Inara
Published: December 2024

Este artigo explora os principais catalisadores utilizados na síntese de amônia, destacando sua importância na otimização da reação entre nitrogênio (N₂) e hidrogênio (H₂). A magnetita (Fe₃O₄) é o catalisador tradicional mais utilizado, permitindo que a reação ocorra a aproximadamente 350 °C e em altas pressões. Contudo, novos catalisadores como os de rutênio (Ru) estão sendo investigados devido à sua estabilidade e eficiência a temperaturas e pressões mais moderadas, o que reduz o consumo energético do processo. Além disso, catalisadores à base de molibdênio (Mo₂C) mostram-se promissores, com alta capacidade de dissolução de nitrogênio, o que pode ampliar a eficiência na síntese de amônia. Suportes como carvão ativado e óxido de cério (CeO₂) ajudam a estabilizar catalisadores, como o Ru/C, elevando o rendimento de amônia sob condições industriais mais econômicas. Estudos também apontam para a wustita, uma forma de óxido de ferro, que oferece propriedades únicas para adsorção de N₂ e H₂, atuando em temperaturas mais baixas. Dessa forma, os estudos sobre catalisadores para a síntese de amônia continuam evoluindo, com alternativas que potencializam a eficiência e reduzem custos. A busca por catalisadores mais ativos, estáveis e menos sensíveis a contaminantes representa uma abordagem essencial para melhorar a viabilidade do processo e atender às demandas industriais de maneira mais sustentável.
Modeling two-phase flow in converging channels using deformable and fixed methods to describe the interface
Authors: Romero Oldrich Joel
Published: December 2024

Several methods have been developed in recent years for the solution of free surface flows. These methods can be divided into two main categories: moving grid methods (also known as Lagrangian or interface tracking methods), and fixed grid methods (also known as Eulerian or interface capturing methods). In the first approach the mesh has grid points on the interface and each computational cell contains the same fluid phase. The principal advantages are the simplification of the imposition of boundary conditions on the interface and the high accuracy of the description of the interface configuration and curvature, therefore, this method should be used to solve problems in which capillary forces are important. In the second approach, the boundary of a two-fluid interface is implicitly “captured” solving a scalar equation – pseudo-concentration method (Thompson, 1986) – on the entire stationary grid, i.e. there is a predefined grid that does not move with the interface. The interface may undergo large deformations, and it is relatively straightforward to handle multiple interfaces. However, the high accuracy of the description of the interface configuration is lost. In this paper, the performance of both approaches is compared by analyzing the interface between two Newtonian liquids flowing in two convergent channels that merge into a single channel. The effect of the flow rate of each liquid and viscosity ratio are analyzed. The differential equations that describe the flow are solved by Galerkin/FEM.
