Authors: Ruiz Jonathan Gustavo Spolador , Moura Jorge Daniel de Melo , Christoforo André Luis
Published: June 2024

Resumo No Brasil, construções em madeira do tipo light woodframe possuem envelopamento estrutural do painel dependente do uso de chapas de OSB (Oriented Strand Board), o que implica em uma dificuldade em seu acesso por parte da população. Para ampliar a aplicação do sistema, uma possibilidade consiste em um projeto não atrelado aos monopólios de componentes construtivos. Uma possibilidade é a substituição da camada de envelopamento estrutural dos painéis por tábuas de madeira serrada convencional. Como objetivo esta pesquisa analisa a viabilidade de utilização e o comportamento de painéis de madeira serrada com envelopamento em tábuas de pinus quando solicitados a esforços horizontais, utilizando modelo numérico de simulações em software. O trabalho estuda cinco diferentes tipologias de painéis: um modelo digital de calibração baseado em experimento ensaiado em laboratório; quatro modelos de diferentes configurações, comparando entre si o desempenho estrutural de cada um com dados publicados na literatura. A modelagem digital utilizou dados experimentais já obtidos em trabalhos anteriores. Dos cinco tipos estudados quanto à tensão-deformação, apenas o Modelo 05 não se mostrou viável pela alta concentração de tensão observada nos conectores. Os demais modelos se mostraram adequados aos critérios preconizados por normas e documentos técnicos referenciados.

Published: June 2024

Abstract Concrete, when exposed to high temperatures, has its properties changed, and the recovery processes depend on the intensity of these changes. This paper aimed to evaluate the influence of high temperatures on concrete properties and verify the effects generated in the material when submitted to natural and fast cooling. Three different concrete mixes were exposed to temperatures of 100 °C, 300 ºC, 450 ºC, and 600 ºC, subdivided into slow and fast cooling groups. With the increase in temperature, cracking processes and microstructural alterations intensified, generating reductions in mechanical strength and increases in absorptions. This study has identified that the elastic modulus was the property most affected by these changes. The correlations between the elastic modulus and the other properties were accompanied by increased concrete micro-cracking, water loss, and decomposition of paste phases. Also, it was found an effect of ettringite rehydration during concrete cooling.

Published: June 2024

Abstract The production of paints using waste from granite and marble processing is a new alternative to contribute to sustainable development in civil construction. However, the lack of studies on the composition and performance of these paints makes the dissemination of this new construction material unfeasible. Therefore, this study aims to investigate the composition of these paints using statistical tools to obtain products with performance compatible with technical regulations and commercial paints. The paint formulations were defined through a quaternary mixture planning. The solids content, pH, viscosity, hiding power, and abrasion resistance were determined for all samples. The paints produced with granite waste showed better hiding power and abrasion resistance, as granite waste has a finer granulometry, in addition to being predominantly composed of silica. Finally, the paints produced in this study and the commercial paints showed similar behavior, which supports the use of waste from the processing of ornamental rocks in paint production.
Briefing: The Net Zero Bridges Group: how can bridge specialists address net zero together?

Published: June 2024

The Net Zero Bridges Group (NZBG) was formed in July 2021, bringing together bridge design and engineering specialists with a shared commitment to decarbonisation. The group's 33 member organisations have declared a climate and biodiversity emergency and committed to taking meaningful and appropriate action. The group's mission is to accelerate progress towards net zero carbon bridges by sharing knowledge and ideas, and shaping best practice. The NZBG's approach is to be curious and open to challenge. It engages with other relevant bodies, including groups representative of bridge owners. The aim is not to duplicate other net zero initiatives, but to build on them to provide bridge specialists with practical data and guidance to use to reduce lifecycle emissions. The NZBG members are developing consistent methods for sharing and benchmarking carbon dioxide data, and considering how decarbonisation processes and philosophies can be applied to traditional and alternative structural materials. The group seeks to understand what makes bridges different to other structures in this regard, and to align with national and client timelines and decarbonisation pathways. This article describes the NZBG, its existing and proposed activities, outlines some essential findings and reflects on the progress and challenges to date.
Sand improvement by microbial-induced carbonate precipitation with casein micelles
Authors: Nakano A.
Published: June 2024

This study explores the incorporation of casein micelles to improve the conventional microbial-induced carbonate precipitation technique used for soil improvement. With a single application of the proposed biocementing agent containing casein micelles, a mixed slurry of natural sand solidified to self-sustaining strength within 48 h at 37°C was obtained. The stress–strain curves of the biocemented specimens obtained from a consolidated drained triaxial compression test exhibited sharp peaks at less than 1% strain. Under effective confining pressures of 30, 50 and 100 kPa, the peak deviatoric stress registered 415, 479 and 536 kPa, respectively – representing 1·8–4·1 times the maximum strength of the original sand. Vaterite calcium carbonate crystals formed by the biocementing agent ensured bridging between sand particles, resulting in the improved cohesion. The cohesion-derived residual strength tended to increase at the critical state in biocemented sand under the lowest confining stress. The localised shear band formed by the crystals may control the movement of sand particles, resulting in a change in volumetric strain behaviour. The formation of casein micelles induced the nucleation and growth of spherical crystals, acting as a casein-mediated vaterite. This formation likely contributed to the improved cohesion of sand observed in this study.

Authors: Wu Chen , Xiao Xiaofei , Xiang Hong , Liu Xuhong
Published: June 2024

The axial compression capacity of steel reinforced concrete (SRC) stub columns with unsymmetrical steel sections (USSs) was investigated in this study. Axial compression tests were conducted on four SRC stub columns with USSs, and internal force analyses were conducted on a total of 22 finite-element models. The failure modes, load–displacement curves and internal forces were used to analyse the mechanical behaviour and bearing capacity of the columns under axial compression. Furthermore, the variables that influence the axial compression capacity comprising different width-to-thickness ratios of the steel flange, area ratio of the steel section to the confined concrete, web eccentricities and steel eccentricities were investigated in a parametric analysis. The results showed that, compared to SRC stub columns with symmetrical steel sections (SSSs), the columns with USSs showed slightly flexural failure. Steel eccentricity was the main factor that affected the axial compression capacity of SRC stub columns with USSs. An equation was proposed for calculating axial compression capacity of an SRC stub column with a USS considering steel eccentricity. Results calculated by the proposed formula showed better agreement with the experimental value than that calculated by the codes, and the formula is also applicable to SRC stub columns with SSSs.

Увеличение количества обрабатываемой информации все больше приводит к необходимости автоматизации ее анализа и развитию соответствующих программных инструментов. Развитие автоматизированной обработки текста как самостоятельного направления на стыке информатики и лингвистики привело к разделению обработки на несколько этапов от выделения знаков — графематического этапа, до автоматического «понимания» смысла текста — семантического этапа анализа. Одним из этих этапов анализа является морфологический, на котором должны быть определены конкретные слова языка и их характеристики, что является важной частью обработки текста в целом, т. к. именно на морфологическом этапе происходит переход от «набора символов» в понимании информатики к «слову» как единице естественного языка. Качество проведения морфологического анализа сильно влияет на точность результатов обработки текста на последующих этапах. В рамках статьи было проведен сравнительный анализ существующих инструментов морфологического анализа текста для русского языка. Для этой задачи использован морфологически размеченный корпус текстов проекта «Национальный корпус русского языка». Одним из сравниваемых инструментов является JMorfSdk, разрабатываемый авторами, как один из модулей фреймворка для обработки естественного языка TAWT. На основе анализа результатов сравнения были предложены и внедрены способы устранения выявленных недостатков, которые позволяют повысить качество проведения морфологического анализа и расширить набор возможностей разрабатываемых инструментов автоматического анализа текстов на русском языке. Среди реализованных улучшений в рамках статьи представлены: автоматическое расширение словаря библиотеки, изменение внутренней структуры словаря («ёфикация», изменение правил работы с инфинитивами), а так же частичное решение проблемы омонимии на основе известных морфологических характеристик соседних слов и накопленной по корпусу текстов их статистики встречаемости.

The work is aimed at creating new, more effective drugs containing succinic acid. For this purpose, a methodology has been developed for transferring the active substance to a nano-sized state, in which the acid, due to an increase in its outer surface, is in the form of clusters, which, upon contact with the mucous membrane, can be more easily absorbed by the body. A complex of physicochemical methods was used to study the effect of immobilization of Succinic Acid (SA) on the surface of hydrophilic, hydrophobic silica and their mixtures on the existing specific surface area and the state of the adsorption layer. It has been shown that during the joint mechanical grinding of crystalline succinic acid with silicas, composite systems are formed in which it is uniformly distributed in the interparticle gaps of silicas and is in the form of nanosized predominantly amorphous clusters. For silicas and their mixtures, the signal of acid crystallites is also fixed on the X-ray diffraction patterns. Additional mechanical treatment of composites with water practically does not change the ratio of amorphous and crystalline components of succinic acid in the surface layer, which indicates its poor solubility in clustered water. This is also confirmed by liquid NMR data, according to which there is no signal from the methylene groups of succinic acid in the spectra. All composites, regardless of the content of SA, treatment with water, and the ratio of the hydrophobic and hydrophilic components, retain a high adsorption capacity with respect to nitrogen. The BET-specific surface of the composites remains at the level of 150 - 200 m2/g. Hydrated forms of hydrophobic silica AM-1 retain the ability to interact with non-polar substances. Using chloroform as an example, it was shown that even at h = 1 g/g, chloroform displaces part of the water from the interparticle space, which manifests itself in a decrease in the interfacial energy of water due to the formation of surface water clusters with a large radius. The hydrophobic silica surface stabilizes the weakly associated form of water, the amount of which can reach 20 mg/g.

Published: June 2024

With trauma representing the leading cause of death in children, and renal injuries representing a large proportion of that trauma, understanding the appropriate management of renal injuries is vital to preventing pediatric morbidity and mortality. Cases involving aberrant anatomy are even more crucial to understand as there is less data on appropriate management. Here, a case is presented of a 7-year-old male presenting after a horse kick to the abdomen resulting in traumatic disruption of a previously unknown horseshoe kidney and the subsequent conservative management. The patient presented with abdominal pain, leukocytosis, and elevated liver function enzymes. An abdominal and pelvic Computed Tomography (CT) demonstrated a horseshoe kidney with a grade IV laceration to the isthmus and left lower pole of the kidney resulting in fracture/disruption of previously fused horseshoe kidneys. Additionally, there was a large retroperitoneal hematoma and hemoperitoneum. The patient was successfully managed with observation, and hemodynamic monitoring and has had resolution of hematoma and preserved kidney function through 8 months of follow-up. In conclusion, this is an example of how a patient with complicated renal anatomy can be managed conservatively to model for potential future cases.

Authors: Morin Paul , Timme Ruth , Moore Michelle , Madson Shauna , Jinneman Karen
Published: June 2024

Salmonella serotypes are defined by two surface structures, O antigen and two H antigens. Traditional serotype determination is performed with the Salmonella serological somatic (O) and flagellar (H) tests and paired with biochemical confirmation. More than 2,600 Salmonella serotypes have been described in the White-Kauffmann-Le Minor scheme. Molecular methods for serotype determination have been developed based on genes responsible for serotype antigens. These genes are encoded in the rfb gene cluster, fliC, and fljB. SeqSero2 is a bioinformatic pipeline that uses whole genome sequence (WGS) data from pure-culture isolates to perform in silico analysis to determine the antigenic formula, including somatic (O) antigens and both flagellar (H) antigens. This provides continuity with the well-established scheme for phenotypic Salmonella serotypes. PURPOSE: This document outlines the steps required to run SeqSero2 v1.2.1 on a collection of isolates in the GalaxyTrakr environment. This is performed by utilizing a custom workflow called “SeqSero2 v1.2.1 collection workflow” and downloading the resulting table. SCOPE: This protocol covers the following tasks: 1. Login or set up an account in GalaxyTrakr 2. Create a new history/workspace 3. Upload data 4. Execute the SeqSero2 workflow 5. Download the results

Published: June 2024

The dynamic development of futsal in Indonesia has encouraged more in-depth research into the physiological characteristics of futsal players. Futsal games have intermittent high intensity, requiring players to continue to move actively together during the match. An equal level of physical condition between players makes it easier for coaches to determine the strategy to use. The aim of this research was to determine differences in anthropometry, aerobic capacity, agility aspects, and speed of semi-professional futsal players based on their playing positions. The method used in this research was an observational study with a quantitative approach. The research subjects consisted of 24 semi-professional futsal players from Bandung city. The results of this study showed that there were significant differences in height and weight variables between goalkeepers and players in other positions (P0.05). In the aerobic capacity variable, there was a significant difference between goalkeepers and players in other positions (P0.05). However, there were no significant differences in the speed and agility variables for all semi-professional futsal players. This study showed that the goalkeeper anthropometry was higher than the field players (pivot, anchor, and flank), while the aerobic capacity of the goalkeepers was lower compared to the field players (pivot, anchor, and flank). There was no difference in speed and agility. Field players had the same physical abilities. The results of the research can be the basis for further research regarding the physical condition needed based on playing positions.

Published: June 2024

Gymnastics is a sport that requires a high level of precision and technical skill, which can be affected by psychological factors. Unfortunately, in many cases, gymnastics training often focuses on developing physical and technical aspects, with little attention paid to psychological factors that may affect athlete performance. This study aims to reveal the role of anxiety and concentration on the performance of gymnastics athletes. The method used in this study was correlational. The study involved thirty-seven young gymnastics athletes (20 girls and 17 boys; mean age 19.03 ± 3.88 years) who regularly participated in or were preparing for competitions. The instruments used in this study include the Competitive State Anxiety Inventory-2R (CSAI-2R), Concentration Grid Test and gymnastics performance based on the assessment of professional judges. The results of this study indicate that anxiety and concentration have a significant influence on the performance of gymnastics athletes. Athletes who are able to manage anxiety stably and concentrate for a long time during competition tend to achieve higher scores in gymnastics performance. These findings underscore the importance of paying attention to psychological aspects in the training of gymnastics athletes. In addition to physical and technical skill development, coaches and administrators should pay special attention to anxiety management and concentration enhancement. Further research could explore specific strategies that can help athletes manage anxiety and improve their concentration to achieve optimal performance in gymnastics competitions.
The Integration of Digital Technology in Task-Design on Eye-Tracking Studies in Geometry
Authors: Bairral Marcelo , Aldon Gilles
Published: June 2024

Eye-tracking (ET) method provides a promising channel for educational researchers to connect learning outcomes to cognitive processes. The main principle of ET is that our gaze and our focus of attention are connected. Due to the advent of digital technologies, eye tracking studies are increasingly growing in different fields and in mathematics education. We assume that the provided task is one of the ways to analyse deeply cognitive processes, and we wonder how ET studies are dealing with the integration of digital technology in task-design in geometry. Starting from Strohmaier et al. (2020) we found three studies, one focused on geometric proofs and two based on construction of geometric objects. We highlight the contributions of integrating digital technology in learning and instruction, and in research in geometry.

Published: June 2024

This work aimed to evaluate the effects of stem morphological alterations resulting from grafting, defined as compatibility and incompatibility between the rootstock and scion, on fruit yield and quality of avocado cv. Hass in three producing areas in Colombia (Rionegro, El Peñol and Anserma) over two consecutive years. Avocado orchards were established by seedlings obtained by grafting Hass scions upon creole rootstock seedlings. Avocado grafted plants were propagated with tip grafting, with a scion bud of cv. Hass (standard procedure). A split-plot design with a blocking factor per locality was used. Main plot corresponded to the harvest season, and subplots to rootstock/scion degree of compatibility. Results showed that compatibility treatments did not significantly affect yield (kg/tree) and fruit number per tree. In 2020, main harvest presented the highest yield (48.05 kg/tree) and fruit number (321 fruits/tree), while in 2021, secondary harvest presented the lowest yield (7.31 kg/tree) and the fruit number (52 fruits/tree). Main harvests contributed with 71.4% for total average production of each year, while secondary harvests completed the fruit yield with 28.6%. Finally, rootstock/scion compatibility did not affect fruit number, fruit caliber distribution, and yield per tree, while yield was affected solely by harvest season.

Influence of aggregate on the structure and properties of concrete
Authors: Murtazaev Said-Alvi Yu. , Salamanova Madina Sh.
Published: June 2024

The dominant role of the binder system and the water-cement ratio has been proven by many studies, but the importance of the aggregate should also be noted, because a large share in the volume of the material belongs to it. By forming a rigid skeleton, the filler participates in the formation of the structure of the composite, and it is it that is responsible for the contact strength with the cement matrix. A study of the physical and mechanical properties and granulometric composition of the filler is necessary to determine the material’s compliance with the requirements of GOST 8267–93. The work carried out on designing the composition of concrete using coarse aggregate from the North Caucasus Federal District made it possible to evaluate the contribution of this component to the process of formation of the structure and strength of concrete stone. Occupying the predominant volume in the mass of concrete, coarse aggregate affects the technical performance, durability and cost of the final product. The study of physical and mechanical properties and granulometric composition of the aggregate will make it possible to correctly design concrete formulations, which is a crucial point in obtaining specified classes of concrete, and will subsequently affect the operational reliability and durability of objects under construction.

Examination of lipid-protein relationships in the red blood cell membranes and placental homogenates of women with obesity and type 2 diabetes mellitus (T2DM) has indicated that activation of lipid peroxidation along with decreased antioxidant defense and imbalance in the placental system of thyroid hormones-thyreotropin. The above impairs the structural and functional properties of cellular membranes, increases lipid microviscosity, and changes the structure of membrane-binding proteins, which correlates with the parameters of glucose and insulin homeostasis and the level of lipid peroxidation. Impaired placental homeostatic processes are a ground to improve therapy aimed not only at compensating T2DM and reversing obesity, but also at eliminating placental insufficiency.

The paper presents the results of studying the sociomedical characteristics of children of the first three years of life, analyzes their parents' medical activity, and identifies risk factors for the development of poor health indicators in the children.
Particular emphasis is laid on the results of teaching the parents by pediatricians in the methods of interactive improvement of their infants' health. The impact of medical literacy of the parents who bring up their infants on positive changes in their health is shown.
The findings suggest that only the active participation of family members, which includes timely complete compliance, can improve health indicators in children.
Prediction of Regional Broadband Strong Ground Motions Using a Teleseismic Source Model of the 18 April 2014 Mw 7.3 Papanoa, Mexico, Earthquake

To estimate predicted ground motion from a teleseismic slip model, we use a low- and high-frequency hybrid method to simulate the regional, strong ground motions observed following the 18 April 2014 moment magnitude (Mw) 7.3 Papanoa, Mexico, earthquake. To generate the regional ground motion at low frequencies (<1 Hz), a teleseismically derived, finite-fault, kinematic model is used to define the earthquake source, taking into account slip-model variations identified with a parameter sampling approach that considers possible errors in the fault geometry, the hypocenter depth, and the rupture velocity. A 3D crustal model is used to calculate the low-frequency ground motions using a finite-element calculation that includes topography and considers variations in the source model to estimate the uncertainty in the calculations. High frequencies (>1 Hz) are added using a 1D full-wave propagation code that estimates uncertainties by considering multiple random distributions of slip with different spatial correlation lengths. The synthetic, broadband (0.05–10.0 Hz) ground motions are obtained by combining the low- and high-frequency portions match filtered at 1 Hz. These synthetic ground motions are compared with the regional observations using velocity records, peak ground acceleration, and medians of the orientation-independent response spectra of the horizontal components (RotD50) calculated at periods of 0.2, 0.3, 0.5, 1.0, 2.0, 3.0, 5.0, 7.5, and 10.0 s. The results indicate that ground motions estimated at these periods using our hybrid approach based primarily on a teleseismically derived source model are comparable to the values observed for the 2014 Papanoa earthquake at regional distances. The approach could be used to estimate strong-motion spectral levels expected for regions with limited local and regional recordings and could also fill in magnitude or distance gaps in ground-motion prediction relations utilized in the assessment of seismic hazard.
Denoising of Dense Spatial Array Data Using the Curvelet Transform

To remove background noise from seismic data recorded by spatially dense arrays, we have developed a space-based denoising procedure using the discrete curvelet transform. Based on a detailed statistical characterization of noise coefficients through the empirical cumulative distribution function method within a pre-event time window, signal and noise can be separated effectively by nonlinear thresholding. After synthetic test, we applied this method on data from an industry 3D seismic experiment recorded at an array deployed near Utica, Ohio. The denoising results show good waveform consistency with a significantly enhanced signal-to-noise ratio. Our curvelet approach allows a more computationally efficient spatial–temporal localization analysis of seismic data than conventional curvelet techniques by avoiding the assumption of stationary Gaussian-distributed noise and can be implemented as a complement of time-domain wavelet methods with fewer frequency losses after denoising. This new method provides a fast and convenient way to recover signals from noisy recordings with dense 2D arrays, leading to a considerable improvement in data quality compared with conventional Fourier, wavelet, and curvelet methods. The partitioned seismic signals and noise would yield advanced earth structure imaging, small-event detection, ambient noise tomography, and others.

This paper examines the plateau effect and the role of Computer-Assisted Pronunciation Training (CAPT) in enabling learners to move beyond the plateau. Specifically, the samples and empirical evidence for this study is provided by StudyIntonation, a top-down CAPT environment supporting visual display of phrasal intonation in the form of pitch graphs presented for both the model pitch of native speakers and attempts of learners. Utterances of model speakers are grouped by situational context, prosodic forms and mode of feedback. The system largely relies upon concepts of sociocultural theory, such as mediation through the zone of proximal development. With the help of an experimental group of high school students, we use mathematical models to pinpoint the Zone of Proximal Development (ZPD), allowing for delivery of tailored task classification based on syntax and discourse tags. Longitudinal pronunciation assessment supported by dynamic time warping and cross-recurrence quantification analysis is used to locate the ZPD, and provide personalized practice. Preliminary experiments for the current study demonstrate that this approach can help learners in overcoming the plateau effect experienced during the learning process. The reported new findings create further grounds for improving and targeting the CAPT system feedback to learners with respect to their individual achievements and differences in learning styles.
Pluralismo Jurídico: uma ponte de aproximação entre a comunidade e a Justiça Restaurativa
Authors: Antunes Grasiele Costa Tiscoski , Wolkmer Antonio Carlos
Published: June 2024

O texto em questão tem como problema introduzir, primeiramente, a discussão da profunda crise paradigmática de acesso à justiça, ao observar os princípios e implementações do Direito Estatal no Brasil, já que diante de novos e contraditórios problemas, não absorve determinados conflitos coletivos específicos. Como resposta, sugere inserir a necessidade de se buscarem formas plurais de fundamentação para a instância da juridicidade. Tais assertivas permitem apresentar o objetivo geral: caracterizar o pluralismo jurídico como tentativa de buscar outra direção ou outro referencial epistemológico que atenda às necessidades atuais. Nesse contexto, a Justiça Restaurativa se coloca enquanto manifestação de pluralidade normativa na sociedade, como representação de uma prática de Justiça Comunitária. O desenvolvimento teórico e sua problematização compreenderão três momentos: inicialmente, a narrativa acerca do pluralismo jurídico; na sequência, a ressignificação da comunidade; e, por último, a entrada em cena da Justiça Restaurativa. O método de abordagem a ser utilizado será o dedutivo, e o procedimento será o monográfico
