Abstract

High-mass stars, born in massive dense cores (MDCs), play a major role in the cosmic ecosystem. Yet, little is known about how MDCs assemble their mass beyond ∼0.1 pc and transport their mass into smaller and denser seeds of stellar embryos (∼100 au) and finally onto HighMass Young Stellar Objects (HMYSOs), which is the key to understand the high-mass star formation processes. Leveraging multi-scale observations at 40–2500 au resolutions toward an MDC with at least one HMYSO associated, we discovered a dynamical system analogous to the barred spiral structures in galaxies. It shows three prominent ∼20,000 au long spiral arms feeding a bar-like elongated structure (∼7,500 au, hereafter denoted as “bar”) at the center. The “bar” further transports gas to a disk through gas streamers. The pseudodisk (>2,000 au) revealed in methanol thermal emission, the Keplerian disk (∼500 au) traced by Class II methanol masers, and the inner disk (∼100 au) traced by long-baseline (0.03 ′′ ) 1.3 mm continuum emission are misaligned. A collimated bipolar outflow is detected launching from the HMYSO. These dynamical features highlight the multi-scale mass accretion through well-organized hierarchical structures during the formation of HMYSOs. Our discovery manifests that this “spirals-bar-disk-outflow” complex exists not only in galaxies as a whole but also in the galactic localized regions where high-mass stars form. The structures and dynamics of galaxies could provide stimulating insights into high-mass star formation, and vice versa.

Abstract

Our research aims to create nanocomposites composed of polyamide 12 (PA12) reinforced with zinc oxide (ZnO) nanoparticles at various concentrations (1.5%, 3%, 5%, 10%, 15%, and 20%) as well as composites composed of polyamide 12 and to use them to adsorb methylene blue (MB). According to adsorption experiments, it has been shown that the adsorption rate varies depending on various factors such as the initial concentration of the solution, contact period, and pH. The various prepared samples were subjected to different analyses such as atomic force microscopy (AFM), optical microscopy, and structural modifications obtained through UV-visible and Fourier-transform infrared (FTIR) spectroscopies. According to the results, it was observed that the PA 12 film becomes less homogeneous and rougher as the amount of ZnO nanoparticles in the PA12 matrix increases. The dye (methylene blue) was absorbed by the polyamide 12 film alone in 20 minutes (pH = 10) and in 5 minutes (pH = 12) for the nanocomposite PA12/ZnO (15%). The increase in the rate and amount adsorbed is due to the strong affinity between the adsorbate and the adsorbent as well as the availability of free adsorption sites on the surface of the bioadsorbent from the first contact.

Published: December 2024

This research aims to determine the effect of providing synbiotics from Probio_FM and Mannan Oligosaccharides (MOS) in the ration on the physical quality of broiler meat at a certain level. The material used was 200 DOC (Day Old Chick) Lohman strain MB 202 Platinum strains produced by PT Japfa Comfeed. Broilers were maintained for 35 days, this study used 5 treatments and 4 replications, namely P0 (commercial feed + 0% Probio_FM and MOS (Control)), P1 (commercial feed + 0.25% Probio_FM and MOS), P2 (commercial feed + 0 .50% Probio_FM and MOS), P3 (commercial feed + 0.75% Probio_FM and MOS), P4 (commercial feed + 1 % Probio_FM and MOS. The variables observed were meat pH, cooking loss and water holding capacity (WHC). Data were analyzed using analysis of variance (ANOVA), if there was a significant effect then it was continued with the Duncan test. The results showed that administration of synbiotics from Probio_FM and MOS had no significant effect (p > 0.05) on the physical quality of broiler meat which included pH value, binding capacity. water, and cooking loss. It was concluded that synbiotics from Probio_FM and MOS could be added to the ration without reducing the physical quality of broiler meat.

Background
Numerous strategies for preventing abusive head trauma (AHT) have been proposed, but controlled studies failed to demonstrate their effectiveness. Digital tools may improve the effectiveness of AHT prevention strategies by reaching a large proportion of the adult population.

Objective
This study aimed to describe the characteristics of videos of AHT prevention published on the internet, including their quality content, and to study their association with popularity.

Methods
From a systematic appraisal performed in June 2023, we identified videos addressing the primary prevention of AHT in children younger than 2 years that were published in English or French on the internet by public organizations or mainstream associations. We analyzed the characteristics of the videos; their quality with the Global Quality Scale (GQS); and their association with an index of popularity, the Video Power Index, using multivariable quasi-Poisson modeling.

Results
We included 53 (6.6%) of the 804 videos identified. Videos were mainly published by public organizations (43/53, 81%). The median time spent on the web was 6 (IQR 3-9) years, the median length was 202 (IQR 94-333) seconds, and the median GQS score was 4 (IQR 3-4). Infants were often depicted (42/53, 79%), including while crying (35/53, 66%) and being shaken (21/53, 40%). The characterization of shaking as an abuse and its legal consequences were cited in 47% (25/53) and 4% (2/53) of videos, respectively. The main prevention strategies in the videos were to raise awareness of the noxious outcome of shaking (49/53, 93%) and convince viewers of the effectiveness of coping strategies for infants’ cries (45/53, 85%). The Video Power Index was positively correlated with the GQS (r=0.38; P=.007) and was independently associated with depicting an infant being shaken (P=.03; β=1.74, 95% CI 1.06-2.85) and the use of text or headers (P=.04; β=2.15, 95% CI 1.08-4.26).

Conclusions
AHT prevention videos had high quality but did not frequently deal with parental risk factors. The characteristics identified as being associated with the popularity of AHT prevention videos could help improve the impact of future prevention programs by enhancing their popularity.

Este artigo é uma espécie de reação aos resultados da pesquisa realizada por Glacy Antunes de Oliveira, Annelise Nani da Fonseca, Ana Flávia Tavares de Melo, Fábio de Castilhos e Fernanda Pereira da Cunha, respondida por 1009 participantes do II Congresso Internacional Online entre Arte, Cultura e Educação: Reconexões da Abordagem Triangular no Ensino das Artes (UFG, 2021). Volto a fazer afirmativas que respondem a algumas das interpretações errôneas e/ou intencionalmente destruidoras da Abordagem Triangular que continuam a circular mesmo depois de trinta anos de pesquisas e transformações positivas pelos arte/educadores que a tem experimentado incansavelmente em suas práticas, dissertações, teses e artigos, aos quais agradeço muito. Faço outras afirmações voltadas para as minhas preocupações atuais como o decolonialismo. Uma destas afirmações que pensava ter deixado muito clara em meus livros anteriores é a influência das ideias de Paulo Freire. Nesse texto faço questão de demonstrá-la didaticamente. Formalmente não escrevi um resumo, mas uma contextualização do artigo tal a importância que venho dando ao contexto em todas as atividades intelectuais. O contexto é decolonizador.

Parametric Study of Vertically Isolated Steel Braced Frames Controlled by Shape Memory Alloys
Authors: Babaei S. , Karimi Ghaleh Jough F. 
Published: December 2024

Abstract
Vertical isolation has gained interest in recent years by incorporating the damping mechanism within the height and evading the concentration of isolation elements in the base. However, dividing the building into separate systems may be less practical in regular buildings. This study used a conventional steel-braced lateral load-resisting system inherently made up of two soft and stiff portions to compare the efficiency of the isolation technique. Shape memory alloys (SMAs) with flag-shaped hysteresis damping mechanisms are assigned among the two subsystems to elaborate the damping mechanism. Parametric coding in OpenSees investigates a large set of frames with altered stiffness of the stiff subsystem subjected to time histories of 40 records with 2 and 10 % probability of exceedance. Increasing the stiffness of the stiff subsystem reduces the interstory and roof drift by more than 30%. SMA employment is shown to be effective in reducing the interstory, and roof drift at the soft- subsystem. The maximum reduction happens on the 1st floor by 32% and the least on the roof by 8%. There was a mild rise in the stiff subsystem’s responses, however, this increase may be neglected as the performance level is governed by the soft- subsystem’s response. The SMA-equipped frame is then further assessed by incremental dynamic analysis. Fragility curves of the system damage states delineate a promising response from the system.
Nonlinear Analysis Methods for Reinforced Concrete Structural Elements Subjected to Static and Dynamic Loads

Abstract
Civil engineering structures are generally designed to be sufficiently ductile and capable of dissipating energy when subjected to movements caused by seismic action. The aim is to study and assess the behavior in terms of global ductility of reinforced concrete beam-column structural elements. Seismic behavior is studied using the push-over method. Initially, we are interested in modeling the nonlinear bending behavior, up to failure, of a reinforced concrete frame under increasing monotonic static loading. The modeling is carried out using the finite element method within the framework of the Navier-Bernoulli hypothesis. The load-displacement curves of the elements analyzed are plotted, enabling the global ductility factor to be deduced. The second part of the work consists of applying the push-over method to a nonlinear static analysis of the frame studied, up to failure, in order to assess its seismic response and deduce its performance point. It was used to obtain the load-displacement curves and to deduce the global ductility factor. After analyzing the nonlinear behavior of the frame using the two proposed methods, approximate global behavior was observed. It was found that in both approaches, the frame exhibits sufficiently ductile behavior, indicating a less advanced state of plasticization. The performance point coincides with the elastic displacement of the frame, so the behavior of the frame has not reached the plastic phase, and the frame can withstand the load applied to it.

Abstract
As we know Ground granulated blast furnace slag (GGBFS) is a by Product and industrial-based pozzolanic substance with high silica content. Utilizing Natural River sand harms riverbanks, drastically alters the water table, and drives up the price of river sand daily. This experimental study utilizes manufactured sand (M-sand) and the by Product as Mentioned in above ground granulated blast furnace slag (GGBFS) which will develop a Special Concrete that is Self compacting concrete (SCC). M-sand is a synthesized material and GGBFS is a byproduct of industrial waste from steel industry. This substance has the potential to produce a sustainable building material. In this study, evolution and mechanical characteristics of SCC produced with M-sand and GGBFS are presented. Six different combinations of partial replacement of cement with GGBFS (0%, 5%, 10%, 15%, 20%, 25%, and 30%) are experimented. In addition to density comparisons, mechanical properties such as Compressive strength, Split Tensile strength, and Flexural strength and fresh quality characteristics such as test of Slump flow for flowability and L-Box Flow through Test for each mix have been compared for 7 days, 28 days, and 90 days’ time periods.
Exploring the Use of Fly Ash and Marble Coarse Aggregates as Eco-Friendly Replacements in Concrete Production

Published: December 2024

Abstract
This study investigates the feasibility of utilizing fly ash and marble coarse aggregates as sustainable substitutes in concrete production, responding to the increasing demand for infrastructure and the necessity to diminish the carbon footprint of construction materials. By partially substituting cement, a material that generates substantial greenhouse gas emissions, fly ash, a by-product of coal combustion, recognizes its capacity to reduce CO2 emissions. The stone processing industry produces marble waste, which, by repurposing otherwise wasted byproducts, offers an environmentally sustainable solution, simultaneously reducing the use of natural resources in the manufacture of traditional aggregates. The research aims to assess the effects of incorporating various ratios of fly ash, ranging from 10% to 50%, and marble coarse aggregates, ranging from 10% to 90%, on the workability, compressive strength, split tensile strength, and flexural strength. The results show a moderate decrease in a slump, with an 18.66% reduction at 50% marble coarse aggregates and 30% fly ash, and a significant increase in compressive strength, with a 60.22% improvement at 56 days with 40% fly ash and 70% marble coarse aggregates. Split tensile strength also improved by 35.50% to 36.66%. Non-destructive tests confirmed the structural integrity of the concrete. This study emphasizes the potential of fly ash and marble coarse aggregates as eco-friendly substitutes in concrete production.

Published: December 2024

Abstract
The context in which this study is conducted is represented by the need to improve road safety at T-intersections, which can be visibility-critical locations and of the risk of accidents. Therefore, this study is important to identify and solve potential problems related to sight distance in road intersections. Case studies on sight distance in intersections are an effective way to assess the impact of the factors that influence it on road safety. Currently, the three-dimensional study allows us to analyze the visibility in detail according to the standards and obtain the sight distance both in tabular format and the graphic representation of the sight distance. The visibility triangle is defined as the spatial region formed by the path of the vehicle traveling along the main road and the vehicle traveling along the side road intersecting leading to the conflict point. The area of the visibility triangle depends on the prescribed sight distances, which must be observed based on the travel speeds of the conflicting paths. In this three-dimensional analysis, the sight distance at the intersection between a national road and an access road to a quarry, in the “T” variant, was studied. In this study, the sight distance checks were made in the “T” shaped intersection according to AND 600, with the help of the 3D model and the Civil Site Design software. Also, the influence of the angle cut slope on the sight distance from the intersections was studied considering 2 slope inclinations namely 1:2 and 1:4.
Dynamic Modeling of Soil-Structure Interaction for Seismic Performance Evaluation of Reinforced Concrete Building

Published: December 2024

Abstract
This study focuses on the effect of soil-structure interaction on the dynamic behavior of structures subjected to seismic movements. A 2D model of a simple minaret, 18.4 meters tall with a width and length of 3.5 meters, was analyzed using the SAP2000 V21 finite element software. Two types of seismic loading were applied: the response spectrum of Algerian seismic regulations (RPA 99 version 2003) for low seismicity (zone: Z1), and accelerograms measured at the Keddara site in Boumerdès, Algeria, in 2003. The soil foundation is classified as type S3 (loose soil), and the analysis included conditions both with and without soil-structure interaction. The results indicate significant impacts of soil-structure interaction: the inclusion of soil effects led to a 25% reduction in base shear and a 15% increase in the fundamental period of the structure compared to the reference model without soil interaction. Additionally, nodal horizontal displacements at the top of the building increased by 40% when accounting for soil-structure interaction, affecting the overall stability and design considerations. This study underscores the importance of incorporating soil-structure interaction in the design process, as neglecting these effects could lead to underestimating the seismic demand and potentially compromise structural integrity.
