The distribution pattern of different plant functional traits in arid and semi-arid areas and their environmental impact mechanism are still unclear. The aim of this study is to elucidate the spatial distribution patterns of four key plant functional traits and the effects of environmental factors on their variation in inland arid and semi-arid areas and thus provide a reference for the prediction of species distribution and biodiversity conservation in this region. We focused on wild seed plants naturally distributed in Xinjiang, and by reviewing floras and data sharing platforms, we sorted and compiled the species list and distribution, plant functional traits and environmental data, including 3,953 species information, 44,302 county-level distribution records, 3,892 plant functional traits information and 29 environmental variables. Spatial and statistical analyses were utilized to detect the spatial distribution patterns of four key plant traits in 50 × 50 km grid cells. The spatial variation in different functional traits was explored and environmental drivers were identified. The results showed that there were significant latitudinal and altitudinal gradient patterns of plant functional traits, and there were significant spatial correlations between different traits. Among the three types of environmental factors (climate, soil and habitat heterogeneity), climate factors played the most pronounced role in explaining functional traits. Mean annual temperature (MAT) was the most important driver of the spatial distribution patterns of each trait. Overall, vegetative and reproductive growth of plants is more favorable in areas with higher temperatures, abundant precipitation, fertile soils and high habitat heterogeneity, which is mainly reflected in higher plant height, larger leaves, earlier flowering time and longer flowering duration.
Long-term persistence of butterfly diversity in a sustainably managed forest ecosystem

Published: February 2025

In recent decades, intensification in land use has led to severe losses of biodiversity across major parts of the world. Studies from Central Europe revealed severe decline of insect diversity across agro-environments, but to a lower extent in forest ecosystems. Sedentary specialist species are suffering particularly, while mobile generalist species are much less affected. Numerous species are also disappearing from nature reserves. On the long run, biodiversity presumably can only be maintained in ecosystems of sufficient size, but is lost in small and isolated habitats. In order to test this assumption, we conducted butterfly counts over a period of 20 years in a large, heterogeneous and sustainably used forest ecosystem in southern Germany. We found no significant changes in diversity and abundance over the two decades of study. However, our data revealed a significant shift in species´ community structure over time, with the proportion of generalist species increasing and the proportion of specialist species decreasing. These changes are most likely due to changes in habitat structures. At the beginning of our study, wind-blows resulting from the heavy storms in the late 1990s represented open areas, but subsequently reforested in the wake of natural succession. Since these temporary open habitats had attracted a particularly high number of specialised species, the observed changes are probably due to these natural processes in a forest ecosystem. In general, our results show that heterogeneous ecosystems of large size may preserve a species-rich butterfly community in the long run.

The technological innovation of terrestrial LIDAR systems has recently given forest planners greater access to key features on forest structure. The Hand Held Mobile Laser Scanner (HMLS) is a recently developed LIDAR tool that is particularly user-friendly and reliable. It is especially useful in the mapping of forest stands, thanks to its implementation of the Simultaneous Location and Mapping Algorithms (SLAM) algorithm. Thus, the present study investigates the ideal walking path to follow during HMLS scanning to survey trees and estimates the biometric parameters of forest stands by testing three distinct schemes. Specifically, two different forest ecosystems are considered in experimental HMLS LIDAR surveys, a beech-dominated deciduous forest and an oak-dominated deciduous forest. Finally, a cost/benefit analysis of each laser survey is analysed according to three walking path models (STAR, GRID, BORDER). A control analysis is also performed of the traditional method without LIDAR. This study contributes to the advancement of a growing body of research on Precision Forestry by considering different characteristics of the forest environment. Regarding practical application, the resulting evaluation of field survey technology can help foresters integrate these techniques into their basic tool kit for forest planning and management processes.

Published: February 2025

Swiss stone pine (Pinus cembra) is a viable solution for afforestation in the high mountain zone, at the upper limit of the forests, due to the species adaptation ability to the limiting climatic conditions. The aim of this study was to analyse the genetic variability, inheritance rate and juvenile-adult correlations, in a 26 years full-sib (10x10 complete mating design) trial, in order to predict the genetic gain of forward selection. In the spring of 2023, measurements and evaluations were carried out for all the existing trees, for Survival rate (Sr), growth (Diameter as breast height- Dbh, Trees’ height- Th, Trees’ volume- Tv) and quality traits (Forks, stem slenderness- Ss, branches’ diameter- Bd, branches’ finesse- Bf, defoliation- Def). The 90 cross-pollinated (CP) families registered 50% of Sr whereas the other 10 selfcross-pollinated (consanguineous) registered just 11% of Sr, and the majority of those trees are dominated and face extinction in the next years. Juvenile-adult correlations were highly significant (p<0.001), indicating that early selection (at the age of 14 years) might be efficient. At the trial age, based on the medium to high heritabilities, the forward selection of the best 10% individual trees from the top 20 of the 90 CP families, for Dbh, could be applied, which ensure at least 9.2% of genetic gain.
Retroalimentación para el Aprendizaje de la Traducción: Estudio de Caso Exploratorio
Authors: Cañada Pujols Maria Dolors , Andújar Moreno Gemma
Published: February 2025

En la didáctica de la traducción, la evaluación y la retroalimentación han suscitado el interés de los académicos (Hurtado Albir, 2019), aunque las investigaciones empíricas todavía son escasas. Nuestro objetivo es contribuir a paliar este vacío relativo, focalizando la atención en las creencias y experiencias de los estudiantes de traducción de los últimos cursos de grado, de una universidad española. El instrumento de recogida de datos ha sido un cuestionario en línea, basado en la propuesta de Henderson y cols. (2016) y adaptado a las características de la evaluación y la retroalimentación en la formación universitaria de traductores. Aunque la muestra se limita a 30 informantes, los resultados aportan información sobre el concepto de retroalimentación de los estudiantes y sobre la frecuencia y utilidad de las modalidades e instrumentos de retroalimentación que han experimentado. Algunos parecen ser más frecuentes que útiles, de lo que se desprende la necesidad de que los docentes se replanteen su manera de evaluar las traducciones para que la retroalimentación que ofrecen sea realmente formativa.

Published: February 2025

Este artículo analiza la complejidad de los entornos docentes en el nivel de bachillerato en Ecuador, destacando desafíos geográficos, económicos y sociales durante el periodo 2021-2022 a partir de los resultados de la Evaluación Ser Estudiante. Su objetivo es explicar los posicionamientos de estudiantes, docentes y directivos alrededor de los entornos docentes. Desde una metodología mixta se construyó un Índice Socioeconómico (ISEC) y un Índice de Recursos Educativos (IRE) para seleccionar las cinco instituciones investigadas. Complementariamente, se realizaron dos grupos de discusión, tres relatos de vida y cuatro entrevistas biográficas a actores del Sistema Nacional de Educación. La investigación revela la sobrecarga laboral de los docentes, la falta de acceso a recursos tecnológicos y educativos, y las desigualdades socioeconómicas que afectan el rendimiento estudiantil. Se destaca el compromiso de algunos docentes a pesar de las dificultades, así como la influencia de las circunstancias socioeconómicas en la elección de la profesión docente. Aunque se observan esfuerzos individuales para fomentar la creatividad y el espíritu de superación, persisten desigualdades estructurales que limitan las oportunidades de acceso a la educación superior y perpetúan un ciclo de desigualdad educativa. Se enfatiza la necesidad de un mayor nivel de justicia educativa en el bachillerato ecuatoriano.

A family of similar plots has been added to the properties (metadata) of primitive plots. The quantitative assessment of the proximity of plots has been introduced.
ЭКСПЕРИМЕНТАЛЬНАЯ ПРОВЕРКА МОДЕЛЬНОЙ ЗАВИСИМОСТИ ТУРБУЛЕНТНОГО ЧИСЛА ПРАНДТЛЯ ОТ ГРАДИЕНТНОГО ЧИСЛА РИЧАРДСОНА

Published: February 2025

Получена формула, связывающая структурную характеристику флуктуаций температуры со скоростью диссипации кинетической энергии турбулентности не через коэффициент турбулентной температуропроводности, а через вертикальные градиенты средней скорости ветра и температуры и турбулентное число Прандтля. Для оценки структурной характеристики температуры по этой формуле предложена модель, основанная на обобщении известных данных о турбулентном числе Прандтля как функции градиентного числа Ричардсона. Экспериментально показано, что временные ходы структурной характеристики температуры, рассчитанной по предложенной формуле и независимо найденной из спектров флуктуаций температуры по данным измерений скорости ветра и температуры акустическими анемометрами на двух высотных уровнях, согласуются между собой. Это подтверждает правильность теоретических построений, на обобщении результатов которых основана используемая в работе модель зависимости турбулентного числа Прандтля от градиентного числа Ричардсона, и открывает возможность дистанционного определения структурной характеристики температуры из измерений скорости ветра и температуры.

A formula has been derived which connects the structural constant of temperature fluctuations with the dissipation rate of the kinetic energy of turbulence not through the turbulent thermal diffusivity, but through the vertical gradients of average wind speed and air temperature and the turbulent Prandtl number. To estimate the structural characteristics of temperature using this formula, we suggest a model based on the generalization of known data on the turbulent Prandtl number as a function of the gradient Richardson number. It has been experimentally shown that the time series of the structural constant of temperature, which is calculated using the proposed formula and independently found from the spectra of temperature fluctuations based on measurements of wind speed and air temperature with sonic anemometers at two altitudes, are consistent with each other. This confirms the correctness of the theoretical constructions, which serve the basic for the model dependence of the turbulent Prandtl number on the gradient Richardson number.
Decline of Interest Rates under Inflation Targeting and Previous Regimes: Evidence from Latin America and Developed Countries
Authors: Chión Chacón Sergio Julio , Álvarez García Kevin Antonio
Published: February 2025

This study empirically investigates the impact of Inflation Targeting (IT) on nominal interest rates over the past 40 years, focusing on 10 advanced and emerging economies. By using a Binary Regime Model embedded within a Backward-Looking Taylor, our findings confirm that IT adoption has significantly contributed to reducing interest rates, with the strongest effects observed in Latin American countries. To reinforce these results, we incorporate Smooth Transition Regression (STR) models, with and without instrumental variables, allowing for a more suitable representation of gradual policy transitions. The STR estimates consistently support our main findings, validating the robustness of the observed impacts. Furthermore, we show that, both before and after IT implementation, central banks display a stronger emphasis on responding to inflation than to the output gap, with this focus intensifying under IT regimes.

Published: February 2025

OBJECTIVE

The Eat, Sleep, Console (ESC) model of care is an innovative care approach for infants diagnosed with neonatal abstinence syndrome, improving patient and health system outcomes for this equity-deserving population. Little is known about sustainably implementing this model into practice. The objective is to map evidence on implementing the ESC model into clinical practice, including strategies, barriers and facilitators to implementation, and evaluation outcomes.

METHODS

Data sources include MEDLINE, Embase, CINAHL, PsycINFO, Google Scholar, and websites identified by a Google search. The study selection included articles exploring the implementation or evaluation of the ESC model in clinical practice since its 2017 conception. Two reviewers independently screened each study using a predetermined screening tool. Data were extracted by 2 independent reviewers from included articles.

RESULTS

The review identified 34 studies. Barriers to implementing the ESC model include resource limitations and systemic oppression and bias. Facilitators include health care provider education and empowerment of parent engagement. The most reported cluster of strategies (31.6%) included training and educating stakeholders. Gaps were noted in the exploration of implementation outcomes/processes, and equity implications on implementation.

CONCLUSIONS

The ESC model of care has been successfully implemented in various settings with positive patient and health system outcomes, including decreased hospital stay and pharmacological treatment of infants. However, there is a gap in exploring implementation processes and outcomes. Future research should explore the contextual elements of the implementation by equitably examining implementation outcomes specific to the ESC model of care.
O tema da escolha na ética de Edmund Husserl
Authors: Silva Bruno Fleck da
Published: February 2025

O artigo analisa o tema da escolha presente na estruturação da ética de Edmund Husserl. A temática presente em Lições sobre a ética e teoria geral dos valores (1908/2009), Introdução à ética (1920/2009) e Europa: crise e renovação (1923/2014) destina à ética o seu local não somente dentro de uma constituição formal e orientadora, mas, sobremaneira, diante da estrutura transcendental da consciência que responde à dimensão material específica da própria ética. A singularidade dos temas da escolha no pensamento ético husserliano permite compreender o contributo da fenomenologia à ética contemporânea na necessidade da conciliação de um plano formal que responda à materialidade conflitiva através do retorno à uma ética que encontra sua base na dimensão antropológica.

Presence and representation of mental health in fiction TV series: King George in «Queen Charlotte» (Netflix, 2023)
Authors: Higueras-Ruiz María-José , Pérez-Rufí José-Patricio
Published: February 2025

The representation of disabled people in TV series remains limited, and characterised by stereotypical portrayals. However, over the past decade VOD platforms have promoted a qualitative and quantitative increase in the production of series featuring such characters. This can be attributed to the enhanced visibility of mental health in contemporary society, as well as the obligation of television to serve as a reflection and socialisation instrument. This paper presents a review of the presence and representation of disability in television fiction series produced in the United States. The main objective of this research is to determine the mental health representation in the character of King George III in the TV series Queen Charlotte. A Bridgerton Story (Netflix, 2023). From a qualitative methodology, we review the related literature and conduct an in-depth textual analysis of the character as a person, role, and actant. Moreover, we examine the scenes which reveal the symptoms of the king’s mental health. The findings show the historical licences adopted by the fiction in favour of the narrative. The symptoms expressed by the king are indicative of a Bipolar I Disorder and Dissociative Identity Disorder: anxiety, verbiage, “races of thoughts,” and identity crisis. In conclusion, this representation stands out for a creative and effective purpose, rather than for being realistic. However, it contributes to the visibility of cognitive disability in contemporary audiovisual projects.

Published: February 2025

OBJECTIVES This study aimed to evaluate the effects of high-intensity aerobic exercise on cardiovascular disease risk factors and inflammatory markers in normal weight obese women aged 20–30 years.METHODS Participants were divided into a high-intensity aerobic exercise group (HIEG, n=8) and a control group (CG, n=7). The aerobic exercise protocol was set at an intensity of 80-85% of the maximum oxygen uptake (VO2max), which was determined through an exercise tolerance test, and consisted of a treadmill workout three times a week over a period of eight weeks. To assess the effects of the exercise intervention, the pre- and post-intervention body composition and VO2max were measured. Additionally, blood samples were collected to analyze cardiovascular disease markers and inflammatory cytokines.RESULTS The results indicated that the HIEG group experienced a significant reduction in body weight and fat percentage (p<0.001) along with an increase in VO2max (p<0.001) compared to the control group. Furthermore, the levels of total cholesterol, low-density lipoprotein cholesterol and triglycerides showed a significant reduction (p<0.01) and inflammatory markers such as tumor necrosis factor-α (TNF-α) and high sensitivity C-reactive protein (hs-CRP) were significantly decreased in the HIEG group (p<0.001). Moreover, high-density lipoprotein cholesterol levels were significantly elevated in the HIEG group (p<0.001).CONCLUSIONS These findings suggest that eight weeks of high-intensity aerobic exercise is effective in improving body composition and promoting positive changes in markers for cardiovascular disease and inflammation in normal weight obese women.
Characteristics of Mechanical Outputs During Rowing Motion: Comparison Between Fixed and Slide Rowing Ergometers

Published: February 2025

OBJECTIVES This study compared the mechanical outputs and lower joint kinematics during rowing motion using fixed and slide-type rowing ergometers to clarify the slide type's characteristics.METHODS Junior rowers performed a simulated 2000m race pace under two ergometer conditions. Rowing motion was filmed by a high-speed video camera (200 fps) from right angles beside the subject and changes in Hip and knee joint angles were measured. Spatiotemporal parameters as well as force output from the handle and stretcher and joint angle kinematics at 500m spot calculated.RESULTS In the 2000m time trial, the two conditions showed no significant difference. However, significant differences were observed in the maximum stretcher force, with the slide-type rowing ergometer showing higher values than the fixed-type rowing ergometer. On the other hand, greater values in handle force were found for the fixed-type rowing ergometer than slide-type rowing ergometer greater. Greater rate of force development for the handle and stretcher were observed in the slide-type rowing ergometer condition. No significant differences were observed in angular changes between the two conditions, but knee and hip maximum angular accelerations were significantly higher in the slide-type rowing ergometer condition. Higher stretcher force in slide-type rowing ergometer at the beginning of the stroke is characterized as the influence of maximal angular acceleration in both knee and hip joint extensions, causing high rate of force development of handle and stretcher forces in the initial phase of the drive. As a result, the muscle groups including the biarticular muscles around hip and knee joints may work in coordination to exert significant force, a defining characteristic of the slide-type rowing ergometer.CONCLUSIONS The fix-type rowing can be used effectively to strengthen the maximum handle pull strength, mainly upper extremity. On the other hand, slide-type rowing can be used effectively to strengthen the maximum stretcher force as well as it’s rate of force development, which might be similar force output of lower extremity as performed during on-water rowing.
Effects of Lifestyle Modification on Sasang Constitution Classification Using the Questionnaire for Sasang Constitution Classification II (QSCC II)

Published: February 2025

OBJECTIVES Sasang Constitution is a traditional Korean medical system that classifies individuals into four types, Taeyangin, Taeeumin, Soyangin, and Soeumin, based on physical and psychological traits. Sasang Constitution is widely used for disease prevention and treatment, emphasizing the potential of personalized healthcare. However, concerns about the accuracy and reliability of diagnostic tools like the Questionnaire for Sasang Constitution Classification II (QSCC II) persist. This study investigates the impact of an 8-week lifestyle modification on Sasang Constitution classification using QSCC II, aiming to enhance the reliability and applicability of this diagnostic tool.METHODS A total of 124 sedentary college students participated in an 8-week lifestyle modification program. The participants were assessed with the QSCC II before and after the program to detect changes in their Sasang Constitution classification. The program consisted of self-directed aerobic and resistance training, performed 3 days/week for 40 minutes, along with dietary changes based on Korean nutrition guidelines.RESULTS After 8 weeks, 33.9% of participants (42 out of 124) experienced changes in their Sasang Constitution classification, with the majority of changes observed in the Soyangin group. Decision tree analysis revealed that changes were strongly influenced by four key QSCC II items.CONCLUSIONS This study demonstrates that the lifestyle modification program influenced responses to certain QSCC II items. The observed changes in responses related to psychological and interpersonal factors may have been due to the insufficient discriminative power of the items themselves. In contrast, physical factors may be influenced by the program, suggesting that these factors could potentially impact the results of Sasang Constitution classification when using the QSCC II.

OBJECTIVES The objective of this study is to examine the motivation, intention, attitude, and perceptions of ease of use, usefulness, and their relationship to sport participation among primary consumers of sport contents on YouTube in university students.METHODS This study employed a questionnaire to examine the motivation, intention, attitude, perceived ease of use and usefulness, and sport participation of YouTube sport contents users in university students. A total of 316 data sets were analyzed. Correlation and multiple regression analyses were conducted to verify the relationships among the factors.RESULTS A notable correlation was identified among motivation, intention, attitude, perceptions of ease of use and usefulness, and sport participation in university students who used YouTube sport contents. The multiple regression analysis revealed that the motivation to seek information, entertainment, and vicarious satisfaction from YouTube sport contents significantly influenced perceived ease of use, perceived usefulness, attitude toward use, intention, and sport participation.CONCLUSIONS The present study corroborates the existence of a significant relationship among factors associated with the utilization of YouTube sport contents by university students. However, subsequent investigations must ascertain the mechanisms underlying the relationship between these psychological factors and sport participation. This entails not only examining the relationships among these factors but also investigating their direct and mediated effects.

OBJECTIVES This study aimed to investigate the morphological changes in anterior talofibular ligament (ATFL) in adolescent athletes with chronic ankle instability (CAI).PARTICIPANTS: A total of 40 adolescent athletes were included, divided into the CAI group (n = 20; age: 17.05 ± 0.75 years; height: 172.35 ± 8.98 cm; mass: 64.12 ± 12.51 kg) and the control group (n = 20; age: 16.50 ± 0.75 years; height: 174.35 ± 8.47 cm; mass: 64.83 ± 11.17 kg). Participants were categorized based on their history of ankle sprains and the criteria outlined by the International Ankle Consortium (IAC).METHODS Musculoskeletal ultrasound imaging was used to assess the thickness and length of the ATFL in both injured and uninjured ankles.RESULTS A significant increase in ATFL thickness was observed in the injured limbs of the CAI group compared to the control group (p = 0.007).CONCLUSIONS The ATFL in previously sprained ankles of adolescent athletes exhibited greater thickness compared to uninjured ankles. These findings align with similar observations in adult populations. Further research is warranted to explore the progression of CAI in adolescents and develop targeted management and treatment strategies.

Published: February 2025

OBJECTIVES The purpose of this study is to investigate the acute effects of stretching performed during rest periods of exercise on performance.METHODS 26 participants were selected from the volleyball team at S University in Chungbuk Province. All participants were fully informed about the purpose and content of the study, experimental procedures, protection of human rights, and the safety of the study before voluntarily agreeing to participate.RESULTS Participants were divided into two groups: one performing static stretching (ASSG) and the other performing dynamic stretching (ADSG). The effects of stretching were evaluated in terms of agility and multidirectional dynamic balance ability. The mean and standard deviation of each variable were calculated, and statistical analyses were conducted using a paired t-test to examine within-group differences based on stretching type and a two-way repeated measures ANOVA for between-group differences. Furthermore, in multidirectional dynamic balance ability, significant differences were found in treatment time, between groups, and across treatment times between groups. Post-treatment comparisons showed improvements in the right anterior (Rt Ant), left anterior (Lt Ant), left posteromedial (Lt PM), and left posterolateral (Lt PL) regions following dynamic stretching.CONCLUSIONS Therefore, it can be concluded that dynamic stretching is highly effective in enhancing agility and multidirectional balance ability when performed during rest periods of exercise. These findings suggest that dynamic stretching can serve as a beneficial training tool for use during exercise rest periods.

Abstract Objective: Evaluate the impact of COVID-19 on elective and emergency hand and wrist surgeries operated in a private orthopedic center. Methods: A retrospective study included hand and wrist surgeries in a private orthopedic center. The total surgeries were computed and separated into elective or emergency surgeries. The numbers were analyzed by month, quarter, and year before and after the pandemic (March 2020). Results: Eight hundred and forty-three surgeries from March 2018 to February 2022 were included. The mean monthly cases of the initial 12 months of the pandemic (15.3) were statistically equal to previous periods (17.3 and 17.2), but the period from March 2021 to February 2022 showed an increase (20.5; p = 0.037). The first four months of the pandemic had a mean (8.3) lower than the previous period (14.0; p = 0.002), but soon there was a significant increase in the following four months (19.3; p = 0.002). As a historical standard, elective surgeries were greater than an emergency in this institution. Still, in the first two quarters of the pandemic, there was a reduction in elective cases, equaling the emergency. Conclusion: An important but relatively brief impact on surgical volume was observed in hand and wrist surgeries during COVID-19. A significant reduction in elective cases happened at the pandemic’s beginning followed by a fast recovery after four months. Nível de Evidência II; Estudo Retrospectivo.

Abstract Background: Regular physical exercise promotes pain relief, reducing the central facilitation of pain mechanisms. Objective: Evaluate the effect of different frequencies of physical exercise (once, twice, or three times a week) on different modalities (aerobic training, stretching training, and strength training), on the pain in the knee joint, and on the level of independence on people with knee osteoarthritis. Methods: Is cross-sectional and used the STROBE-Checklist: cross-sectional studies. A total of 193 elderly people were evaluated, pain and functional independence were analyzed. Results: For the pain variable, there was a statistical difference in favor of the intervention in the comparisons control versus strength 1 and 2 times a week and stretching 3 times a week already in the Lawton variable, only the comparison control versus aerobic 1 time a week did not prove to be statistically dignified. Conclusion: The exercise modality and the weekly frequency seem to affect the perception of pain, stretching exercises performed three times a week, as well as muscle strengthening exercises, regardless of weekly frequency are efficient in joint pain analgesia. Practicing muscle strength exercises, regardless of weekly frequency and aerobic and stretching exercises at least twice a week, increases and/or maintains IADL.

ABSTRACT Concrete is the most used construction material, which results in harmful impacts on the environment due to the consumption of natural resources. Hence the need to use alternative materials, e.g., waste from the construction sector and even from other production sectors. This context includes the development of concrete with sustainable functionality, such as pervious concrete with the incorporation of waste foundry sand (WFS), a waste generated by the foundry sector. However, there is a scientific gap focusing on the environmental viability of pervious concretes. In this sense, this study aims to evaluate the toxicity of pevious concretes with WFS, through germination tests with Eruca sativa (arugula) and Triticum aestivum (wheat) seeds. The statistical analysis of the results showed that there was no significant harmful effect from the incorporation of WFS on the germination rate for both seeds used. Regarding root growth, it was observed that WFS II concrete (>% Portland cement) had a lower impact on arugula seeds (more sensitive). Therefore, the pervious concrete with WFS developed was found to be safe in relation to phytotoxicity.

Abstract Heat treatment used in milk powder processing cannot always inactivate spore-forming microorganisms. Toxin deterioration and production by some species are significant concerns for the dairy industry, making the identification of these microorganisms essential for solving problems with the quality of the products. Given this scenario, this study sought to quantify and identify the predominant species in milk powder, aiming to know the isolated genetic varieties. Fourteen samples were analyzed for aerobic/anaerobic, mesophilic, and thermophilic bacterial spore presence, totaling 52 analyses. Spore contamination was verified in all samples analyzed, and the thermophilic spores had the highest contamination levels. 16S rRNA sequencing revealed 47 isolates: Weizmannia coagulans (21%), Anoxybacillus flavithermus (5.3%), Clostridium butyricum (5.3%), Bacillus amyloliquefaciens (2.6%), Geobacillus stearothermophilus (2.6%), Clostridium pabulibutyricum (2.6%), Clostridium sporosphaeroides (2.6%), Bacillus licheniformis (2.6%), Bacillus sp. (34%), Geobacillus sp. (15.8%), and Clostridium sp. (5.3%). The results indicate the need to establish control measures to improve the hygiene and processing conditions of powdered milk, thereby ensuring product quality and consumer safety.

Abstract In the present study, a cost-effective and eco-friendly approach is being explored to remove the harmful dye Congo red from synthetic wastewater, using an equatorial strain of Rhodococcus biphenylivorans. The immobilized cells’ Congo red-decolorizing activity in calcium alginate showed an increase of 217% compared to the free cells. By improving the alginate concentration to 4% (w/v), the bead diameter to 3 mm and using 50 beads, a 67% decrease in the time required for complete decolorization was accomplished. Both free and immobilized cells followed first-order kinetics for the elimination of Congo red, with immobilized cells displaying a decolorization rate 3.2 times greater than that of free cells, resulting in an 84% reduction in half-life. The immobilized cells displayed the capability to remove 0.10 g/L Congo red without any significant decline in their efficiency for up to twelve cycles, offering an economic advantage due to their reusability. Examining the decolorized products of Congo red showed no hindrance in the germination of Triticum aestivum and Vigna radiata, indicating the effective removal of all toxic components from the original dye via the biological method. Therefore, this strain has significant potential as a biological agent to eliminate wastewater contaminated with Congo red efficiently.

Abstract Glioma brain tumors have similar textural patterns to other tumors, making their detection and segmentation a challenging process. The approach of the Modified Tumor Detection System (MTDS) is presented in this study to identify and categorize brain images of gliomas from images of healthy brains. The Spatial Gabor Transform (SGT), feature calculations, and deep learning structure comprise the training work flow of the suggested MTDS technique. The features are computed from the glioma brain image dataset images and the normal brain image dataset images and these features are fed into the classification architecture. In this paper, the proposed IVGG architecture is derived from the existing Visual Geometry Group (VGG) architecture to improve the detection rate of the proposed system and to decrease the computational time complexity. The testing work flow of the proposed system is also consist of SGT, feature computation and the IVGG architecture to produce the classification result of the source brain images into either normal or glioma. Furthermore, the Morphological Segmentation technique has been used to find the tumor locations in this glioma image. Two separate brain imaging datasets have been used in this study to evaluate and validate the suggested MTDS's performance efficiency. BRATS Imaging 2020 (BI20) and Kaggle Brain Imaging (KBI) are the datasets. Analysis of the performance efficiency has been done in relation to the Jaccard index, recall, precision, and detection rate.
Numerical investigation on wind pressure mitigation in low-rise building roofs using spoilers with PID control
Authors: Bianchin Gabriela Penna , Braun Alexandre Luis
Published: February 2025

Abstract A numerical investigation is performed in this work to evaluate the influence of controlled spoilers on pressure mitigation over low-rise building roofs. Considering that low-rise buildings are susceptible to severe damages caused by wind action, spoilers are utilized along the roof windward edges to reduce the aerodynamic load, which are controlled using PID control techniques. Numerical simulations are carried out using a semi-implicit Characteristic-based Split algorithm, where linear tetrahedral finite elements are employed for spatial discretization in a standard Galerkin procedure. Turbulence modeling is performed using Large Eddy Simulation and the flow fundamental equations are written considering isothermal and incompressible conditions in arbitrary Lagrangian-Eulerian kinematical description to consider the spoiler angular motion. Two and three-dimensional simulations are carried out using a low-rise building model, where the influence of controlled roof spoilers is evaluated. Wind tunnel predictions are utilized to validate the numerical formulation proposed here.
