Getting there: How commuting time and distance impact students’ health
Authors: Chairassamee Nattanicha , Chancharoenchai Kanokwan , Saraithong Wuthiya
Published: December 2024

This study investigates the impact on Thai students’ health of commuting to school, both in terms of time and distance. The individual-level dataset used in this study is obtained from the National Statistical Office (NSO) and limited to students aged from 9 to 18 years old, with 25,461 respondents. While the data were collected in 2016, with mostly unchanged commuting behaviors of Thai students, our results can reflect current health impacts from school commutes. The data indicate that traffic in Bangkok causes students to commute longer to schools than in other provinces. The results from the ordered logistic regression consistently show that commuting time has stronger negative impacts on health than commuting distance does. In other provinces, our results show that long commuting time and distance negatively affect physical and mental health of students. The present study also indicates that investigating either commuting distance or commuting time could bias the results in some sequences.

Sinalização de risco de desastres no Brasil: um dos caminhos para a redução do risco de desastres
Authors: Firme Paulo , Teixeira Lima Liziane Vasconcelos
Published: December 2024

A adoção de uma cultura voltada para a gestão do risco de desastres é um grande desafio. Dentre as várias ações relacionadas com a preparação para emergências, destaca-se a instalação da sinalização de risco nos territórios. Dentre os elementos de auto proteção, ela se destaca como mais simples e de rápida percepção, além de materializar os trabalhos desenvolvidos voltados para o mapeamento e a identificação de riscos. Nesse contexto, o presente artigo pretende refletir sobre a necessidade de criação de um sistema nacional de sinalização de riscos e desastres voltado para a padronização da representação gráfica da Codificação Brasileira de Desastres (COBRADE). Para a formulação e produção do conhecimento apresentado foram estudados manuais e documentos nacionais e internacionais relacionados com o tema, sendo realizada uma abordagem exploratória e qualitativa baseada no método dedutivo e comparativo. Considerando, a bibliografia estudada e os diversos exemplos e modelos de placas de sinalização de riscos no território, pode ser identificada que não existe uma padronização nacional. Quando comparado com outra situações, como a de regulação do trânsito por veículos e pedestres, percebe-se que a adoção de uma padronização facilita a percepção das pessoas e cria a interação necessária entre o modelo abstrato dos mapeamentos para a percepção concreta das pessoas que vivem ou que passam por um determinado local que é classificado como área de risco.
The role of children in the construction of food heritage
Authors: Guedes Codogno Camila
Published: December 2024

Este artigo, fruto de uma reflexão apresentada no “8º Colóquio Internacional DIAITA Luso-brasileiro de História e Culturas da Alimentação” com a temática “Da natureza, senhora da mesa, à mesa, mestra da natureza” tem como objetivo provocar a seguinte reflexão: podem as crianças exercer papel ativo na construção dos patrimônios alimentares? Para tanto, propõe-se apresentar as vivências e representações infantis de crianças brasileiras em diferentes contextos socioculturais, um indígena e outro não indígena, acerca das relações estabelecidas com os alimentos, o que inclui a percepção da variedade e sazonalidade alimentar. As referências teóricas para tal intento são embasadas nos campos da Antropologia da Infância, bem como nos estudos acerca das culturas alimentares. Além disso, busca-se uma interpretação seminal do fenômeno a partir de um problema típico da modernidade: a separação (ou conjunção) entre natureza e cultura, como propõe Bruno Latour. A metodologia utilizada é oriunda de observação participante em pesquisas de campo ocorridas em diferentes tempos e espaços: a primeira, uma etnografia entre as crianças indígenas Galibi-Marworno do Amapá (2006) e a segunda, fruto de um projeto de extensão sobre o PNAE (Programa Nacional de Alimentação Escolar) realizado no interior de Minas Gerais (2018).

Authors: Shah Jehangir , Sun Hao , Qiao Zijun , Sharif Talha , Gul Misbah
Published: December 2024

Methylene blue is an organic contaminant that is produced by the plastic, textile, and dye industries. Many studies have been undertaken to investigate the cleanup of methylene blue from industrial effluents. SrO nanoparticles are now being utilized to remove methylene blue colours from water. We used a hydrothermal technique to create strontium oxide nanoparticles for photocatalytic MB breakdown under light conditions. To enhance the solar light activity and avoid charge recombination, we employed a hydrothermal technique to add Ni as a dopant in strontium oxide nanoparticles. Strong base NaOH, nickel nitrate, and strontium nitrate were used as precursors. The nanoparticles were crushed into powder and calcined at 450 °C in a muffle furnace to produce SrO and Ni-doped SrO nanoparticles. The nanoparticles were analyzed using several analytical methods to determine their morphological and structural properties. At 309, 312, and 317 nm, UV-Vis spectroscopy showed absorbance values of SrO doped with varied nickel concentrations. The Ni–O stretching peak was identified in the FTIR analysis of strontium oxide nanoparticles at 402 cm-1 and 581 cm-1, whereas the Sr–O bond gave a signal at 854.84 cm-1. SEM images of Ni-doped SrO nanoparticles were created at various magnifications. The nanostrips are hexagonal and cylindrical. Sherrer's equation was used to compute the average crystalline structure, which showed that the diameters of pure and Ni-doped SrO (2 percent, 3 percent, and 4 percent) nanoparticles were 45.54 nm, 36.14 nm, 42.93 nm, and 41.21 nm, respectively. According to the EDX examination, the relative concentration of Ni-doped SrO is about 72 percent Sr and oxygen, with around 1.34 percent Ni. The resulting sample was tested for photocatalytic degradation of organic pollutants in aqueous solution, such as methylene blue, and the completion of the reaction was monitored using UV-visible spectroscopy to measure the % photocatalytic degradation during light illumination. According to the UV-visible spectra, 90% of the dye was effectively destroyed.

Published: December 2024

Cinnamomum zeylanicum is an aromatic species with essential oil in its leaves, stems, and roots, widely used in traditional medicine and culinary applications. The essential oil of C. zeylanicum exhibits various biological activities, such as antioxidant and antifungal properties. This study aimed to evaluate the essential oil extracted from the leaves of C. zeylanicum collected during two seasonal periods in the Brazilian Cerrado, focusing on its volatile chemical profile, and antioxidant, and antifungal activities. Leaves of C. zeylanicum were collected in July and December 2023. The essential oil was extracted through hydro distillation. The volatile chemical profile was determined by gas chromatography-mass spectrometry (GC-MS), antioxidant activity was assessed by DPPH free radical reduction, and antifungal activity was evaluated based on the inhibition of Sclerotinia sclerotiorum, Colletotrichum gloeosporioides, and C. acutatum. Two major compounds were identified: eugenol (72% and 63%) and eugenyl acetate (9% and 15%) for the dry and hot seasons (July) and the wet and hot seasons (December), respectively. DPPH free radical reduction showed maximum inhibition of 89% and 65% for July and December, respectively. Antifungal activity demonstrated maximum inhibition rates of 65% and 53% for S. sclerotiorum, 82% and 71% for C. gloeosporioides, and 56% and 27% for C. acutatum during the same periods. This study highlights seasonal variations in the major compounds of essential oil, which influenced its production, DPPH radical scavenging activity, and inhibition of the evaluated fungal strains.
Fractional order models of viscoelastic polymeric solids undergoing large deformations
Authors: Hálková Barbora , Beneš Michal
Published: December 2024

We present a fractional order model for nonlinear visco-hyperelastic solids taking into account large deformations. A three-field form of the Hu-Washizu principle is introduced to create a stable finite element method in the context of nearly incompressible dynamics. The β-method (a generalized midpoint rule) for time discretization is implemented into a variational finite element framework for efficient computing of numerical approximations to the initial boundary-value problem for hyperbolic equation of motion. Finally, a 2-D cantilever beam problem with a step end load is considered in order to demonstrate the algorithm.

Coagulation factor II thrombin receptor as a promising biomarker in breast cancer management
Authors: Dong Yan-Ming , Bao Guo-Qiang
Published: December 2024

This study aims to comprehensively investigate the role of coagulation factor II thrombin receptor (F2R) in breast cancer (BC) and to evaluate its potential as a biomarker in this context. Data on female BC were retrieved from the TCGA database. Comparative analyses were performed, including enrichment analysis, tumor immune microenvironment analysis, drug sensitivity testing, molecular docking, and cell-based experiments, to assess the expression and function of F2R in BC. Statistical analyses and graphical representations were conducted using R software. The study confirmed a significant upregulation of F2R in BC, which was associated with a more favorable prognosis. Clinical correlation analysis revealed a strong association between F2R expression and key clinical parameters, such as estrogen receptor and progesterone receptor status. Additionally, genes co-expressed with F2R were significantly linked to various biological processes, including cell cycle regulation, oxidative phosphorylation, ribosomal function, and extracellular matrix interactions. F2R also showed associations with immune modulators, particularly CD200 and NRP1. Drug sensitivity analysis, molecular docking, and cell experiments consistently demonstrated positive correlations between F2R expression and sensitivity to dasatinib. This study underscores the potential of F2R as a valuable biomarker in BC, providing insights into the molecular mechanisms underlying tumorigenesis.
Detection and tracking of safety helmet wearing based on deep learning
Authors: Liang Hua , Yang Liqin , Chen Jinhua , Liu Xin , Hang Guihua
Published: December 2024

Failure to wear a helmet correctly is a significant cause of injury or death in the construction industry and industrial production. Traditional supervision methods predominantly rely on manual oversight, incurring substantial costs and demonstrating inefficiencies. To address this pressing issue, the present work introduces an advanced intelligent detection technology based on deep learning algorithms, which leverages the YOLOv5 algorithm to train a dataset, enabling real-time assessment of correct helmet usage among personnel while promptly issuing warnings when deviations are detected. Simultaneously, to mitigate challenges related to object leakage and false detections in complex backgrounds, the model’s performance is further enhanced by optimizing Generalized Intersection over Union, Distance Intersection over Union, and Complete Intersection over Union loss functions and improving the Mosaic-9 data enhancement algorithm. Empirical results validate the system’s efficacy, with the optimized YOLOv5 algorithm achieving an impressive precision rate of 93.16% and a robust recall rate of 88.96%. These findings underscore the system’s ability to accurately identify instances of workers’ improper helmet usage. This enhanced YOLOv5-based intelligent detection technology provides a more efficient and accurate method for monitoring helmet compliance within the construction industry and industrial production, effectively addressing the limitations of traditional manual supervision and ensuring precision in complex operational contexts.
Re-evaluating Cambaztepe in the Context of its Yamnaya (Pit-Grave) Origin, the Anatolian Trade Network and Possible Early Migrations towards Anatolia in the 3rd Millennium BC
Authors: Sezer Okan
Published: December 2024

This study aims to re-evaluate Cambaztepe, located approximately 12 km west of the Silivri district center of İstanbul, where rescue excavations led by the İstanbul Archaeology Museums in 2015 were carried out. Cambaztepe is a burial mound dated to the Early Bronze Age II (EBA II) within Anatolian chronology. It also has a secondary burial context dated to the Iron Age. Although there is no absolute dating, Cambaztepe is currently believed to be the earliest burial mound in Türkiye’s European territory (also known as Eastern Thrace), considering the burial position and the grave goods and/or finds. The excavation team has published only a preliminary report and two papers, of which one was published in a popular magazine. The possible relationship between Cambaztepe and Yamnaya (Pit-Grave), and other related cultures was not examined in the preliminary report. Furthermore, the preliminary report provides inaccurate and misleading suggestions about the way the deceased were placed in the grave and the grave finds. In addition to other evidence, the way the deceased were placed in the grave as a semi-supine position indicates that the Cambaztepe EBA II grave context is related to the Pit-Grave or other cultures with Pit-Grave traditions in the Balkans. However, the grave structure in round shape with a floor of stone slabs and the grave finds, consisting of a beaked jug of inland Western Anatolian origin and a dagger of Anatolian origin, make Cambaztepe different from contemporary burial mounds in the Balkans. The existence of a cremation burial is sufficient to make concrete suggestions in the context of possible early migrations from Europe to Anatolia in the 3rd millennium BC, even though the exact nature of these migrations remains unknown, whether they involved the population movement or transfer of ideas-ideology-beliefs (or a combination of both). Likewise, the Cambaztepe EBA II grave context has a potential to define the mechanism of migration from Anatolia to Europe more precisely. The Cambaztepe EBA II grave context should be placed at the date range 2700–2500 BC, based on the burial practice observed in the Balkans and the grave finds of Anatolian origin.
The role of osteoprotegerin (OPG) in exercise-induced skeletal muscle adaptation
Authors: Owens Aaron , Dos Santos Livia , Brook Matthew , Hunt John , Piasecki Mathew , Piasecki Jessica
Published: December 2024

Objectives

The purpose of this narrative review is to offer an updated perspective on the current research on the glycoprotein Osteoprotegerin (OPG), including its potential therapeutic impact and mechanisms of action, and interaction with bone and muscle tissues.

Content

As health and social care advances people are living longer, with projections suggesting that in 2050 there will be 2 billion people who are aged over 60 years. Yet musculoskeletal health still declines into older age and as a result there is an increase in the proportion of older populations that spend more time with persistent disabilities. Although physical exercise is repeatedly demonstrated to minimise detrimental effects of ageing, it is not always a feasible intervention, and other directions must be considered.

Summary and outlook

OPG, a glycoprotein decoy receptor for the receptor activator of nuclear factor kappa-β ligand (RANKL) is a key regulator of bone formation yet emerging evidence has presented its potential to offer positive outcomes in regard to the preservation of skeletal muscle mass and function. Animal models have shown that OPG levels increase during exercise, and independently acts to restore losses of muscle strength and reduce bone resorption. Interventions to increase circulating OPG alongside exercise may act as a therapeutic target to combat the decline in quality of life in older age in humans. Further research is needed on the mechanisms of its action and interaction in humans in combination with exercise.
Democratie comme forme de vie versus democratie comme regime: une fausse antinomie?
Authors: Klimis Sophie
Published: December 2024

Para alguns, o abandono por parte de Castoriadis, no início dos anos 1970, da ideia de que o proletariado, como “classe”, seria o agente da revolução socialista, teria marcado o fim da sua filosofia militante e uma guinada a uma atividade estritamente intelectual. Contrariamente a essa crítica, Castoriadis redefinirá, a partir dos anos 1980, o campo e o objeto revolucionário como projeto de autonomia, no qual incluirá a prática pedagógica e psicanalítica. É a partir desse solo que o filósofo pensará a possibilidade de uma instituição social da autonomia, o qual encontra, como sua condição de possibilidade histórica, a construção de uma sociedade verdadeiramente democrática. Explicitar os fundamentos desse projeto prático-poiético é o que pretende a autora nesse artigo.
Cornelius Castoriadis: psicanálise e democracia
Authors: Castillo Monique
Published: December 2024

Castoriadis praticou três ofícios: a economia, a psicanálise e a filosofia. A noção de significação religa esses três domínios: as significações associam o indivíduo à sociedade e sua história comum é feita por meio de sua atividade criadora recíproca e contínua. Atualmente, temos necessidade de dar novo impulso à noção de significação porque ela tornou-se matéria-prima na sociedade de comunicação, nos obrigando a repensar a economia, tanto quanto a educação e a política. A descoberta de Castoriadis é capital: ele compreendeu que os humanos não vivem em um mundo de coisas, nem mesmo em um mundo de representações, mas em um mundo de significações. Ora, as significações não são apenas cognições, elas são também motivações. Como elas são, a uma só vez, representações e práxis, elas tornam o projeto de autonomia um projeto revolucionário, à condição de pensarmos toda a complexidade da autonomia. Tal é o que nos propomos aqui.
Educação e ethos democrático: o desafio da formação para a autonomia
Authors: Ferreira Evandson Paiva
Published: December 2024

Neste artigo discuto, a partir da obra do filósofo Castoriadis, o modo como a escola é concebida na Modernidade, considerando-se a noção da formação para a cidadania e como o significado de cidadania e de autonomia ganham outro sentido, à medida que a instituição escolar vai sendo dominada pela lógica da vida empresarial. A escola, instituição que participa das duas significações imaginárias modernas, autonomia e controle, também participa do processo de privatização do indivíduo e do eclipse do projeto de autonomia. Cada vez mais submetida aos valores do controle, da normatização, da produtividade, do sucesso individual, da meritocracia, do quantificável, encarna e reforça um novo tipo de heteronomia disfarçado em democracia e autonomia.  Discutiremos também essa banalização da educação, a maneira como a escola torna-se cada vez mais distante de um ideal de formação de subjetividades reflexivas e deliberantes, e mais comprometida com a formação de recursos humanos.
Sobre algumas repercussões da ontologia do social-histórico de Castoriadis para a teoria sociológica
Authors: De Farias Alberto Luis Cordeiro
Published: December 2024

O artigo é uma exposição de alguns dos fundamentos da compreensão do social-histórico por Cornelius Castoriadis, orientada por uma perspectiva teórico-sociológica. Procuro pensar em que sentidos pode a consideração da ontologia social de Castoriadis nos ajudar a repensar, e eventualmente reconfigurar, o domínio da reflexão teórico-social sobre o mundo. Ao mesmo tempo, procura-se medir o alcance do reordenamento que os pressupostos dessa ontologia implicam para o nível pressuposicional – elementos ontológicos, epistemológicos e metodológicos – e teórico – categorias, conceitos e enunciados gerais – na sociologia. Ao construir a sua compreensão do histórico-social, Castoriadis não só postulou uma nova forma de inteligibilidade, como também se deparou com a necessidade de pensar transições, como as passagens da interioridade monádica à intersubjetividade social primária (do ser ao social), e desta às configurações histórico-sociais estabilizadas (do social à sociedade), dessa maneira aproximando-se de alguns topoi e alguns dos níveis de teorização que compõem àquilo que chamamos de teoria sociológica. O texto encerra, programaticamente, com alguns desafios que o pensamento de Castoriadis lega à reflexão teórico-social sobre o mundo.
LIPOMA EM Cavia porcellus - RELATO DE CASO
Authors: De Freitas Santos Simone , Calais Júnior Antonio , Soares Renzo , De Souza Ferraz Matos Laura , Rossi Jr João Luiz
Published: December 2024

Lipomas são tumores benignos originados da proliferação de células adiposas, podendo afetar várias espécies domésticas. Embora não haja predileção por gênero, eles são pouco documentados em porquinhos-da-índia (Cavia porcellus). Este estudo de caso detalha o diagnóstico e tratamento de um lipoma em uma fêmea de C. porcellus, com cerca de três anos, que apresentou um nódulo subcutâneo na região axilar esquerda. A nodulectomia, foi conduzida sob anestesia geral, empregando dexmedetomidina, midazolam e cetamina para indução, além de isoflurano para manutenção. A recuperação pós-operatória transcorreu sem complicações. A análise microscópica revelou uma proliferação celular densa, encapsulada e expansiva, com um discreto estroma fibrovascular. Os adipócitos exibiram diferenciação acentuada, apresentando citoplasma repleto de um amplo vacúolo que deslocava os núcleos perifericamente, com sutis atipias celulares, caracterizando-o como um lipoma. Através do histórico clínico, sinais apresentados e avaliação histopatológica, confirmou-se o diagnóstico de lipoma clássico no nódulo subcutâneo em questão. Este caso enfatiza a possibilidade de desenvolvimento espontâneo de lipomas em C. porcellus e destaca a eficácia do tratamento cirúrgico como a abordagem mais apropriada.

Radiographic Evaluation of The Bone Density Around Tooth-Anchored One-Piece Immediate-Loading Dental Implant
Authors:   College of Dentistry, University of Duhok , Duhok, Kurdistan Region, Iraq., Karam Bangen Mohammed , Selivany Bahar Jaafar , Qasim Huda Jameel , Mohammed Rafah Hussein
Published: December 2024

Background: Immediate loading of dental implants has gained attention for its potential to enhance patient satisfaction and reduce treatment time. However, limited data exists on its effects on bone density around tooth-anchored, one-piece compressive implants. This study evaluates the impact of immediate functional loading on bone density changes using radiographic grayscale and texture analysis over one year.
Materials and Methods: A total of 68 patients (mean age: 56 ±8.2 years) received 89 distal implants in free-end partial edentulous sites. Cone beam computed tomography (CBCT) was used for treatment planning, and intra-oral digital radiographs were taken at baseline (T0), six months (T1), and one year (T2). Functional loading began seven days post-implantation using fixed porcelain-fused-to-metal (PFM) prostheses. Grayscale values and texture parameters, including mean, standard deviation (SD), and coefficient of variation (CV), were analyzed in regions of interest (ROIs) around the implants.
Results: Significant increases in bone density were observed across all ROIs between T0 and T1 and T0 and T2 (P<0.05). Between T1 and T2, differences were less pronounced but still indicated stabilization.
Upper ROIs: Significant changes (P<0.05) were observed across all time intervals except CV between T1 and T2 (P>0.05).
Lower ROIs: Consistently significant improvements (P<0.05) at all time intervals.
Mesial ROIs: Significant differences in SD and CV across all intervals (P<0.05), with notable mean changes between T0 and T2.
Distal ROIs: Early significant changes (T0-T1, P<0.05) in SD and CV, with stabilization by T2 (P>0.05).
Conclusion: Immediate functional loading enhances bone density, particularly within the first six months, with continued stability over one year, demonstrating its effectiveness for tooth-anchored one-piece compressive dental implants.
Keywords: Bone density, Immediate loading, Dental implants, One-piece implants, Radiographic analysis.
Post Traumatic Impaction of Maxillary Deciduous Central Incisor: A Case Report
Authors:   College of Dentistry, Cihan University, Erbil, Kurdistan Region, Iraq., Majeed Bahoz Himdad
Published: December 2024

Background and Objectives: Primary tooth impaction is a rare phenomenon when compared to permanent teeth impaction, particularly in upper front teeth. The problem could be either a physical blockage of the eruption or a malfunction of the eruption process.
Methods: This case study describes a 4-year-old girl who experienced incomplete eruption of her upper right baby front tooth due to an injury. The unerupted tooth was surgically removed. Regular check-ups were recommended to monitor the development of her teeth and ensure sufficient space for her permanent front teeth.
Results: This case study describes an unusual situation where a baby's upper front tooth failed to erupt. that associated with trauma. That caused delay in progression of the permanent successor compared to the contralateral permanent central incisor. And by extracting the impacted primary tooth a path of eruption opened for the permanent successor tooth so it will accelerate the progression of erupting the permanent successor and mostly may erupt in the same time of the contralateral tooth.
Conclusions: It's crucial to closely watch the eruption of permanent and deciduous teeth to spot and address any issues with tooth eruption early on.
Keywords: Primary incisors, Childhood trauma, Impacted tooth.
Enhanced photocatalytic and filtration properties of carbon-doped g-C3N4 membranes reinforced with nanofibrillated cellulose
Authors: Xiong Beiyue , Liu Yirong , Zheng Wenbiao , He Xiaoxiao , Ye Chengning , Xue Hanyu , Xia Jianrong , Gao Renjin , Wang Liwei
Published: December 2024

Carbon-doped g-C3N4 was synthesized using a simple high-temperature process (calcination at 550 °C for 4 h). One-dimensional nanofibrillated cellulose (NFC) materials were then inserted into the two-dimensional g-C3N4 material by vacuum filtration method at room temperature. The prepared g-C3N4/NFC composite membranes were systematically characterized using a series of techniques, such as XRD, FTIR, and SEM. The results showed that the carbon-doped photocatalysts possessed a narrow band gap, which prolonged the visible light absorption and favored the organic pollutant degradation. The incorporation of NFC enlarged the interlayer spacing, leading to an increase in the water flux. The water flux of C0.02CN/NFC (15%) composite membranes reached 73.7 L•m-2•h-1•bar-1, which is more than that of g-C3N4/NFC membrane. At the same time, the carbon doped composite membranes showed enhanced retention and photocatalytic degradation ability. The retention rate of the C0.02CN/NFC (5%) composite membranes could reach 89.3% from 80.8% after three-cycle photocatalytic experiments. The membrane maintained a good retention rate and feed flux, which confirms the composite membrane has good self-cleaning ability and stability. It could potentially be applied for water treatment.

Idiopathic Annular Ventricular Arrhythmias
Authors: Yoneda Zachary T , Stevenson William G
Published: December 2024

Idiopathic arrhythmias originating from the mitral and tricuspid annuli are commonly encountered in clinical practice. This review focuses on distinguishing features of ventricular arrhythmias arising from these structures and the importance of distinguishing idiopathic arrhythmias from those associated with structural heart disease. Each region along the mitral and tricuspid annuli (including the cardiac crux and para-Hisian region) is then discussed separately, with a particular emphasis on the ablation strategies and pitfalls for each. Although this review series is centred around idiopathic ventricular arrhythmias, the strategies for ablation techniques in these regions are broadly applicable.

This controlled in vivo experimental study examines the impact of two periosteum preparation techniques on microcirculation during bone augmentation with isogenic bone grafts in rats.

Methods:

Twenty female Lewis rats were divided into two groups (n=10 each). In one group, the periosteum was prepared with a conventional periosteal elevator; in the other, a piezoelectric device was used. After graft implantation at calvarial sites, intravital microscopy was performed post-operation (day 0) and on days 3, 8, and 28 immediately to assess microvascular parameters: functional capillary density, blood flow velocity, and vessel diameter. Statistical analysis was conducted using ANOVA on ranks with p<0.05.

Results:

The piezoelectric device group showed higher mean values for functional capillary density, blood flow velocity, and vessel diameter than the conventional instrument group, though differences were not statistically significant.

Conclusions:

This study suggests that periosteum preparation with a piezoelectric device does not significantly differ from conventional methods regarding microcirculatory outcomes. Either method appears viable for preserving microcirculatory integrity during bone augmentation. Further research in larger models and clinical contexts is recommended to confirm these findings.

Since 10 May, 2018, a significant number of volcanic and seismic events have been recorded in Mayotte, in the Comoros Archipelago of the Indian Ocean. Detailed bathymetry of Mayotte′s eastern regions has uncovered steep underwater slopes. A recent study in the area investigated liquefaction-prone layers associated with low sea-level depositions. However, the reason for the presence of such ‘weak zones’ remained unknown. In the present study, we examined samples from Mayotte’s slopes to investigate the reason for liquefaction at the particle-scale of such layers. Our results show that biogenic particles in naturally sedimented environments can crush under cyclic or static loading even with large amounts of fines. In the case of Mayotte’s slopes, the external loading threshold was found to be 500 kPa under K0-conditions. Our findings highlight the complex behavior of biogenic-dominant sediments, their impact on classification and overall behavior, and their potential implications for the design of wind farms.

La presente investigación se ubica en la línea de educación en derechos humanos, la cual busca abordar el campo de las relaciones sociales entre hombres y mujeres en el contexto social del municipio de Soracá, Boyacá. Del mismo modo, pretende identificar los efectos que la violencia estructural tiene en las relaciones de poder en las familias y cómo desde la participación de los hombres en procesos de educación en derechos humanos se puede disminuir este tipo de violencias. En cuanto al proceso metodológico, la investigación es de corte cualitativo y como técnica el grupo focal; como categorías de análisis se establecieron: identidad individual, familiar y colectiva con perspectiva diferencial. Como resultado, se observa que las reacciones de los hombres antelos cambios sociales, culturales y económicos han hecho que la violencia en la mayoría de los casos se haya comprendido desde un acto impetuoso, donde en la mayor parte de los casos el abordaje directo de la víctima es la mujer. Finalmente, como conclusión se plantea que el goce efectivo de los derechos humanos implica pensar en aspectos transversales como lo son mayor equidad, el reconocimiento de derechos, la prevención y protección, la atención integral, la inclusión social de grupos vulnerables y la justicia social.
1921 ve 1924 Anayasalarında Hükümet Sistemleri: “Karma Sistem” Kabulünün Eleştirisi
Authors: Şahin Engin
Published: December 2024

Türkiye’de, Cumhuriyetin kuruluş yıllarında sırasıyla iki anayasa yürürlükte olmuştur. 1921 Anayasasının hükümet sistemi literatürde “meclis hükümeti sistemi” olarak kabul edilmektedir ve bu konuda büyük ölçüde görüş birliği mevcuttur. TBMM tarafından kabul edilen ikinci anayasa ise 1924 Anayasasıdır. 1924 Anayasasının hükümet sistemi hakkında literatürde görüş birliği mevcut değildir. Ancak büyük oranda bazı yanlarının “meclis hükümeti sistemine”, bazı yanlarının “parlamenter sisteme” benzediği iddiasıyla “karma sistem” olarak adlandırılan hükümet sistemi olduğu düşünülmektedir. Bu makalede “karma sistem” kabulüne karşı çıkılarak, 1924 Anayasasının hükümet sisteminin neden “parlamenter sistem” olarak kabul edilmesi gerektiği organik ve fonksiyonel açıdan yapılan bir sınıflandırma ile detaylıca anlatılmaktadır.
Online Dispute Resolution as Legal Disruption: What Effect Could It Have on the South African Dispute Resolution Landscape?
Authors: Cupido Robin
Published: December 2024

Across the world, the legal profession has typically been slow to adapt to technological changes. The South African legal profession is no exception to this, despite the fact that technology has the potential to facilitate and innovate many aspects of the practice of law. One such aspect is the field of dispute resolution, where it has been established that technology can be used to reimagine how disputes are resolved, looking outside of the traditional litigation model. Used in this way, technology becomes a disruptive innovation, changing the traditional dispute resolution practices carried out in the legal world.
The aim of this work is to provide an explanation of what a disruptive innovation is and to discuss whether technology can be such an innovation in the South African dispute resolution landscape. This discussion will comprise a general examination of the legislative framework and current uses of technology in South African law. In the context of dispute resolution, it is suggested that online dispute resolution (ODR) embodies a disruptive innovation. An exploration of ODR follows, with the goal of determining whether it is a sustainable alternative to traditional litigation and whether it is feasible to include this innovation in South African law.
South Africa Aims to Increase Financial Inclusion to 90 Percent by 2030: Plausible or a Mere Ideal?
Authors: Ncube Menelisi
Published: December 2024

According to the National Development Plan (NDP) Vision 2030 of South Africa, South Africa aims to increase financial inclusion for everyone to 90 percent by 2030. However, a few challenges have arisen over the course of the years after the drafting of the NDP Vision 2030. This article will first trace some of these challenges under the category of practices that diminish the integrity of banks in South Africa. These challenges include banking fraud (phishing and vishing), automated teller machine (ATM) bombings and cash in transit heists (CITs), the unfair treatment of banking customers as well as the greylisting of South Africa by the Financial Action Task Force (FATF) resulting in failure to fully complying with international standards regarding the prevention of money laundering (ML), terrorist financing (TF) and proliferation financing (PF). It is also apparent that there are no clear guidelines or protocols that accompany the NDP Vision 2030 to comprehensively detail how the 90 percent financial inclusion target for all people in South Africa will be attained. In addition to this, the NDP does not provide any consequences to the stakeholders responsible for the promotion of financial inclusion and/or any exigency plans should 90 percent fail to be achieved by 2030. Undoubtedly, the above-mentioned challenges to financial inclusion place doubt on the achievement of 90 percent financial inclusion by 2030. This article aims to critically investigate these challenges that may have the potential to hinder the optimum achievement of financial inclusion in contemporary South Africa. Furthermore, this article will critically analyse the relevant legislation as well as related policies and regulations aimed at promoting financial inclusion in South Africa. Ultimately, the article will propose measures which may be useful in attaining 90 percent financial inclusion in South Africa by 2030 as per the NDP Vision 2030.

Background. In swimming championships, strategy setting is considered to be the main factor, especially in the middle and long-distance events. Implementing a strategic change can indirectly affect the final results.
Objectives. The study aimed to find out whether there were any significant differences in reaction time (RT), final time (FT), and strategy for each split time (ST) in the men’s and women’s 400 meters freestyle events at the Olympic Games held in Tokyo (2021), Rio de Janeiro (2016), and London (2012).
Materials and methods. This study used quantitative methods with a sample size of 48 athletes. The data source included using the secondary data. Descriptive statistics are presented in the form of means and standard deviations. The Shapiro–Wilk test was used to test the normality of the data. To compare RT, FT, and ST data, the one-way ANOVA test was conducted. The linear regression test was used to determine the effect of RT on the first ST.
Results. The findings of this study indicate that there were differences in the RT of male athletes during the 3 Olympics. The study also revealed variations in average speed. In general, swimmers accelerated their speed at ST1 and ST8. This occurred at the Tokyo 2021 and Rio de Janeiro 2016 Olympics, while at the London 2012 Olympics, swimmers accelerated their speed only at ST1. Additionally, the results demonstrated that RT had an influence of 0.381 (14 %) on the first ST in male athletes, whereas the influence in female athletes was less marked — 0.066 (4 %).  
Conclusions. This study concludes that ST1 and ST8 are the most crucial components in the 400 meters freestyle swimming for both male and female athletes. Coaches and athletes must be very careful in carrying out special training at the tapering stage so that athletes can achieve the right time to produce the best performance.
Vaccinium virgatum (Ericaceae): A species to be recognized
Authors: Fritsch Peter W. , Crowl Andrew A. , Manos Paul S.
Published: December 2024

Since its original publication in 1789, Vaccinium virgatum has been treated by most authors as an accepted species in V. sect. Cyanococcus. In the latest comprehensive taxonomic treatment of the section, however, it is treated as a synonym of the broadly circumscribed species V. corymbosum. Here we use a combination of morphology, ploidy assessment with flow cytometry, and previously published phylogenomic analysis based on high-throughput DNA sequencing to support the taxonomic status of V. virgatum as a species to be recognized. As circumscribed here, V. virgatum occurs in the southeastern U.S. Coastal Plain from Arkansas, Texas, and southeastern Oklahoma to northeastern Florida and southeastern Carolina. An updated taxonomic treatment of the species, including an expanded description, distribution map by county, and a representative list of specimens examined by county is included. We provide a means of distinguishing V. virgatum from V. ashei, a similar species recently also segregated from V. corymbosum, and from presumed rabbiteye blueberry escapes from cultivation, which can occur both within and outside the native range of V. virgatum. We designate a neotype for V. virgatum and lectotypes for V. virgatum vars. angustifolium, parvifolium, and speciosum.
