This paper comprehensively summarizes and discusses the latest research progress in the underwater concrete structure damage repair technology of infrastructures. The prompt application of underwater concrete structure repair technology can effectively deal with the damaged parts of underwater concrete structures, and it can ensure the safe and stable operation of infrastructure and extend its service life. Firstly, this study uses bibliometric methods to analyze the characteristics of the literature on research into underwater concrete repair in the past 30 years (1993–2023), and expounds the research status and hotspots of this field. Then, we conduct a comprehensive classification and discussion of the underwater concrete structure damage repair technologies at the current stage. This technology can be divided into two major types: direct underwater type and dry environment type. Further, the development history of these technologies is systematically sorted out and, combined with practical engineering application cases, the operation processes, applicability, limitations, and economy of these technologies are analyzed. Finally, the challenges and future development trends of the current underwater concrete structure damage repair technology are pointed out, which provides a direction for future research on the intelligent maintenance of underwater concrete structures.
A Network-Based Clustering Method to Ensure Homogeneity in Regional Frequency Analysis of Extreme Rainfall
Authors: Billios Marios , Vasiliades Lampros
Published: December 2024

The social impacts of extreme rainfall events are expected to intensify with climate change, making reliable statistical analyses essential. High quantile estimation requires substantial data; however, available records are sometimes limited. Additionally, finite data and variability across statistical models introduce uncertainties in the final estimates. This study addresses the uncertainty that arises when selecting parameters in Regional Frequency Analysis (RFA) by proposing a method to objectively identify statistically homogeneous regions. Station coordinates, elevation, annual mean rainfall, maximum annual rainfall, and l-skewness from 55 meteorological stations are selected to study annual maximum daily rainfall. These covariates are employed to investigate the interdependency of the covariates in Principal Component Analysis (PCA) as a preprocessing step in cluster analysis. Network theory, implemented through an iterative clustering process, is used in network creation where stations are linked based on the frequency of their co-occurrence in clusters. Communities are formed by maximizing the modularity index after creating a network of stations. RFA is performed in the final communities using L-moment theory to estimate regional and InSite quantiles. Quantile uncertainty is calculated through parametric bootstrapping. The application of PCA has a negligible effect on network creation in the study area. The results show that the iterative clustering approach with network theory ensures statistically created homogeneous regions, as demonstrated in Thessaly’s complex terrain for regionalisation of extreme rainfall.

Published: December 2024

Biofloc technology (BFT) is an advanced aquaculture method that uses microbial communities to enhance water quality and support aquatic species cultivation. Our research aims to delve into the pivotal role of aeration intensity within BFT systems, revealing its influence on microbial community structures, water quality, and nutrient cycling for L. vannamei culture. Three aeration levels were set with intensities of V75 (75 L/min), V35 (35 L/min), and V10 (10 L/min). The results showed that the lowest aeration intensity (V10) resulted in larger floc sizes and a reduction in the 2D-fractal dimensions, indicating a decreased overall structural complexity of the bioflocs. In addition, water quality parameters, including total ammonia nitrogen and nitrite, remained low across all treatments, highlighting the water-purifying capacity of biofloc. While protein and lipid contents in biofloc did not differ significantly among treatments, docosahexaenoic acid (DHA) levels were highest in the V75 treatment, suggesting that higher aeration promotes the accumulation of essential fatty acids. RDA analysis revealed that microorganisms like Ruegeria sp. and Sulfitobacter mediterraneus negatively correlated with ammonia and nitrite levels, suggesting their key role in converting ammonia to nitrite and nitrate in marine nitrogen cycles. The functional annotation of metagenomes across different aeration levels showed the similarly active roles of microorganisms in nitrogen metabolism and protein synthesis. In conclusion, while variations in aeration intensity affect floc size and the accumulation of essential fatty acids in biofloc, they do not significantly impact overall water quality or core microbial functions in L. vannamei aquaculture. Future research should focus on the effects of aeration strategies on microbial community dynamics and the integration of these data with performance metrics in L. vannamei. These insights can help optimize biofloc cultivation and enhance environmental sustainability in the aquaculture industry.

Sludge management is a very relevant aspect in the operation of Wastewater Treatment Plants (WWTPs). In activated sludge systems, it is common to have daily (or continuous) monitoring of total suspended solids in the aeration tank (MLSS). If such control is not properly performed, it can cause solids to wash out in the secondary sedimentation tank or significantly impact BOD (Biochemical Oxygen Demand) and nitrogen removal. There are many commercially available systems which can provide real-time monitoring of solids (mainly optical or ultrasound sensors). Even though commercially available (usually with a high cost), there are still issues related to the use of such sensors. The most important one is the progressive accumulation of solids, which cause measurement errors. In this work, the authors investigated the application of a low-cost US sensor for MLSS (mixed-liquor suspended solids) monitoring in two full-scale activated sludge WWTPs. The tested sensor was similar to a previously described device, which had been previously employed in a pilot-scale UASB reactor in Brazil. The main differences were related to an integrated treatment and acquisition system which allowed real-time treatment of the US wave as well as data acquisition at a predefined time. The values generated by the sensor were compared with a commercial optical sensor installed in the same WWTP and double-checked with periodic gravimetric tests. The results at a Leeuwarden WWTP showed that the measurements of the US sensor, the optical sensor, and gravimetric test did not present significant differences during the test period at a significance level of 5%. Absolute errors were on average 0.04% (US sensor) and 0.03% (optic sensor) of MLSS compared to the gravimetric test. Although the use of the tested US sensor for monitoring solids in WWTP is promising, there are still several improvements that need to be made to the sensor. These include implementing a more precise calibration frequency, establishing a cleaning routine, and preventing sensor fouling. Furthermore, the sensor still needs a more thorough cost–benefit analysis, which would help assess the practicality of implementing this technology in various WWTPs.

Essential tremor (ET) is one of the most common neurological disorders. The main manifestation of the ET is upper-limb action tremor, often accompanied by other motor as well as non-motor symptoms. Modern therapeutic options for the treatment of ET are limited due to a limited understanding of the etiology, pathomorphology and pathogenesis of ET. There are several risk factors for ET: elderly age, family history, genetic predisposition, environmental factors (organochlorine pesticides, ethanol, lead and mercury compounds, beta-carboline alkaloids). At the pathomorphological level, degenerative changes of the cerebellum and, less often, pathological changes in the locus coeruleus, substantia innominata, dorsal nucleus of the vagus nerve, substantia nigra and other parts of the brain are detected in ET. The inferior olive, cerebellum, nucleus ruber, thalamus and cerebral cortex, combined into a single cerebello-thalamo-frontal system, are involved in the pathogenesis of ET. There are several different hypotheses of the mechanisms of tremor occurrence: the neurodegenerative hypothesis, the hypothesis of the central oscillatory network, the GABAergic hypothesis and the hypothesis of the effects of β-carboline alkaloids

Traumatic brain injury (TBI) remains one of the main problems in modern neurosurgery and neuroresuscitation. Among the working-age population, severe traumatic brain injury and combined trauma is one of the leading causes of persistent disability. Neurological symptoms, depending on the severity of TBI, vary from focal manifestations, such as central paresis, conduction disorders of sensitivity, disorders of higher cortical functions, to diffuse, such as the development of autonomic dysfunction, central respiratory and cardiovascular disorders, which often negatively affects the prognosis in this category of patients. One of the neurological syndromes complicating the acute period of severe TBI is the syndrome of paroxysmal sympathetic hyperactivity (SPSH). The main manifestations of SPSH are episodes of autonomic dysfunction with the development of tachycardia, arterial hypertension, tachypnea, hyperthermia, hyperemia of the skin, with an increase in the degree of depression of consciousness, increased muscle tone and sweating and irritation of the diencephalic structures on electroencephalography. Clinical manifestations are of the nature of a ‘vegetative storm’. Sympathetic paroxysms can develop from 1 to 15 times a day, with a duration of 10 to 30–40 minutes. The development of SPSH in the clinical picture of severe TBI increases the risk of infectious and hospital complications. Despite the vivid clinical picture, differential diagnostics of SPSH is a complex task due to the need to exclude a large number of comorbid pathologies. The issues of pathogenesis, diagnosis and treatment of SPSH remain unexplored. Assessment scales and algorithms for differential diagnostics of SPSH are being actively introduced into clinical practice, which is certainly of interest to doctors at neurotraumatology centers.
Understanding access to sexual and reproductive health in general practice using an adapted Candidacy Framework; a systematic review and qualitative evidence synthesis
Authors: Mawson Rebecca , Hodges Victoria , Salway Sarah , Mitchell Caroline
Published: December 2024

Abstract Background General practice has a key role in reducing inequity in access to sexual and reproductive health (SRH). Unplanned pregnancy, abortion and STIs are increasing and disproportionately affects deprived communities and ethnic minority groups. The candidacy framework offers a practical, theoretical framework for understanding the complex interactional processes of access to SRH in general practice. Aim To use the candidacy framework to explore access of SRH in general practice. The seven interaction stages include, identification of need, navigation of services, permeability of services, appearing and asserting need, adjudication by healthcare professional, offers or resistance of offer and the local operating conditions or local production of candidacy. Design and setting This study involved a systematic review with qualitative evidence synthesis using a framework approach. Methods A systematic search of MEDLINE, EMBASE, PUBMED, and the Web of Science was conducted to identify primary qualitative research studies exploring access to SRH in general practice from practitioner, public, and patient perspectives in countries with universal healthcare. The candidacy framework was used to synthesise the findings. Results Analysis of 42 studies revealed the impact of stigma, shame, and embarrassment among individuals, communities, and healthcare practitioners. Findings showed limited inclusion of demographics such as ethnicity and socio-economic status. Barriers to access were more evident for those from lower socio-economic communities, ethnic minorities and LGBTQ+. There are multiple barriers, which include the behaviours of healthcare professionals who have a crucial role in recognising an individual’s SRH need. Conclusions General practice offers a cradle-to-grave healthcare service, which should have SRH as a priority area of provision. Further understanding is needed of the impact of historic harms by medicine and healthcare on racialised individuals and gender minorities
HEPATOPROTECTIVE EFFECT OF BLACK CUMIN (Nigella sativa) AGAINST THE LIVER Aspartame-induced Rattus norvegicus BASED ON HISTOPATHOLOGICAL FEATURES
Authors: Mukharomah Katrine Adiansyah Dwi , Sayekti Fitria Diniah Janah
Published: December 2024

Foods and beverages containing artificial sweeteners in the form of aspartame are widely consumed in various countries including Indonesia, and have increased every year. Excessive consumption of aspartame can increase the occurrence of hepatotoxicity in the liver such as changes in the histopathological picture of the liver characterized by degeneration and cell necrosis (cell death). Hepatoprotectors are compounds that have antioxidant benefits so that they can protect the liver by reducing oxidation reactions in liver damage. One compound that functions as a hepatoprotector is black cumin (Nigella sativa). Aims: This study aims to determine the effect of black cumin administration on macroscopic and microscopic observations of liver organs in male white rats induced by aspartame. Methods: This study was experimental with 5 treatment groups including 1 normal group, 1 negative group and 3 aspartame and black cumin treatment groups. Liver tissue is observed macroscopically based on color, texture and size, while microscopically it is done by assessing the presence of normal cells, degeneration and necrosis. The results. The results of microscopic observations showed that the negative control and treatment groups showed cell damage in the form of cell degeneration and necrosis. The results of the study based on the ANOVA test obtained a significance value of 0.05 which means there is an average difference between groups and continued with the Tukey test. Conclusions: Based on Tukey's test, the fourth group (K4) is a treatment group with the most effective dose of black cumin in preventing liver cell damage to white rats, which is 0.2 ml / 200 g body weight / day.

Published: December 2024

Los suelos de la Amazonia Colombiana presentan limitaciones para la agricultura, por lo que el desarrollo de sustratos a partir de materiales locales, como las semillas de Asaí (Euterpe precatoria Mart.), surgen como una solución innovadora. Se evaluaron tres sustratos realizados con semillas de Asaí trituradas con estiércoles de vaca (T1), cerdo (T2) y gallinaza (T3), junto con un tratamiento control (T4). Los sustratos se sometieron a pre-compostaje para estabilizar los materiales, y se evaluó la variación de temperatura y pH final. El diseño fue completamente al azar, con 12 unidades experimentales de sustrato y suelo (1:1). Se aplico prueba de Tukey (α = 0.05) por el paquete estadístico Infostat. Para medir su influencia se midió altura, numero de hojas y número total de frutos en plantas de tomate Cherry (Solanum lycopersicum Var. Cerasiforme). Los resultados mostraron que T2 y T3 promovieron un mayor crecimiento y número de frutos en comparación con tratamiento control. El tratamiento T2 resultó ser el más eficiente en todas las variables evaluadas. Los sustratos enriquecidos con semillas de Asaí, combinados con estiércol de cerdo y gallina, se presentan como una alternativa viable para mejorar la producción de tomate en la Amazonía colombiana.

Published: December 2024

Introdução: Os aneurismas micóticos cerebrais representam uma entidade clínica extremamente rara e de alta morbidade, frequentemente associada a casos graves de endocardite infecciosa. Materiais e métodos: Os dados foram obtidos por meio de revisão de prontuário da paciente, exames complementares da mesma e revisão de literatura. Relato de caso: A paciente inicialmente apresentou um quadro de cefaleia, associada a rigidez de nuca e sonolência, com piora progressiva ao longo de quatro dias, e refratário ao uso de analgésicos. Buscou atendimento médico e foi submetida à punção lombar, cujo resultado sugeriu um quadro de meningite bacteriana. Posteriormente, foi encaminhada a uma unidade especializada em medicina tropical, onde, na admissão, foi identificada uma hemorragia intraventricular e uma área hiperdensa na região talâmica. A investigação por ressonância magnética (RNM) de crânio revelou hipersinal em T2 e Flair, além de focos hipointensos em SWI, sugerindo a hipótese diagnóstica de malformação arteriovenosa. A angiografia cerebral subsequente revelou um aneurisma distal na artéria pericalosa, sugerindo um padrão micótico. A paciente foi submetida a terapia antibiótica com ceftriaxona, e após 14 dias de tratamento, uma nova angiografia cerebral não mostrou evidências de lesões aneurismáticas. Conclusão: O diagnóstico de aneurismas cerebrais micóticos deve ser considerado em casos de meningite complicados por hemorragia intraventricular, exigindo um alto nível de suspeita clínica e uma avaliação detalhada. Devido à sua raridade, os aneurismas micóticos devem ser sempre contemplados como um possível diagnóstico diferencial em casos de meningite bacteriana complicada por hemorragias intraparenquimatosa e ventriculares.

O câncer hepático é uma neoplasia maligna desafiadora, com acentuadas dificuldades relacionadas à necessária intervenção cirúrgica no equilíbrio entre a ressecção do tumor e a preservação de tecido hepático viável. Abordagens tradicionais são baseadas em ressecções amplas, o que resulta em insuficiência hepática e grande morbidade. Entretanto, técnicas cirúrgicas baseadas na ressecção anatômica e/ou na embolização portal seletiva apresentam resultados animadores ao reduzir a perda de tecido hepático saudável e melhorar a resolutividade pós-operatória.

Queimaduras graves e extensas continuam representando um desafio significativo no cenário clínico devido às dificuldades associadas à regeneração dos tecidos lesionados, em conjunto com o risco elevado de inflamação exacerbada, infecções e cicatrização excessiva. A aplicação de terapias celulares, especialmente o emprego de células-tronco mesenquimais (C-MSCs), tem apresentado resultados promissores na estimulação da recuperação dos tecidos afetados. As C-MSCs possuem a capacidade de se diferenciar em diversos tipos celulares, além de liberarem fatores de crescimento que estimulam a formação de novos vasos sanguíneos enquanto reduzem a inflamação na região da lesão. Este estudo explora os progressos no emprego de C-MSCs para a reparação de tecidos em casos de queimaduras severas, examinando como isso influencia o processo de cicatrização, a diminuição de complicações, além de beneficiar os resultados tanto funcionais quanto estéticos.

Corn is an alternative source of carbohydrates besides rice and wheat. Corn is used as feed in the livestock industry and various processed foods. BPS data for 2023 shows that corn production is decreasing, which has an impact on corn self-sufficiency and a lack of corn fulfillment for export needs. The research aims to determine the effect of interactions between soil processing systems and weed control on the growth and yield of hybrid corn plants. This research uses factorial RAK with interactions. The first factor is the tillage system with levels T0 (no tillage) and T1 (tillage). The second factor is weed control time with levels G0 (weed free), G1 (weeds controlled at 15 HST), G2 (weeds controlled at 35 HST), G3 (weeds controlled at 55 HST). The results showed that the tillage system and weed control time were significantly different in the test BNT 5%. However, the interaction not significantly different in the test BNT 5%. Corn plants with tillage (T1) and weed free (G0) showed the best growth and yield compared to other treatments in all observed variables.

This study investigates the long term aging effects on polymer materials used in Photovoltaic (PV) modules, with a focus on evaluating their durability, reliability, and safety over extended operational periods. Polymers in PV modules play a critical role in encapsulating and protecting sensitive components from environmental exposure, but they are also subject to degradation due to prolonged exposure to UV radiation, temperature fluctuations, and moisture. This research assesses the aging mechanisms affecting polymer performance, utilizing accelerated aging tests that simulate various environmental conditions to predict material lifespan under real world conditions. Through a combination of thermal, mechanical, and chemical analyses, this study identifies key degradation factors and evaluates their impact on the structural integrity and functionality of PV modules. Findings reveal significant correlations between specific aging stressors and the degradation of polymer materials, which may contribute to efficiency loss and safety risks over time. This study distinguishes itself from existing Technology Acceptance Model (TAM) based e-learning studies by focusing on a comprehensive analysis of polymer degradation mechanisms specific to photovoltaic modules. Unlike prior studies, it evaluates real world conditions through a blend of mechanical, thermal, and chemical analyses, offering unique insights into improving PV system reliability. This research provides insights that can guide manufacturers and engineers in optimizing polymer materials for sustainable and safer PV module applications, particularly in climates with harsh environmental conditions.
