Authors: Mhawish Ayah Hameed , Risan Hussam K.
Published: June 2024

The dynamic behavior of retaining walls is a complicated subject and a considerable design challenge, particularly under seismic conditions. Seismologists and investigators have an interest in near-fault earthquakes with significant velocity pulses because it can cause considerable displacements in constructions with respect to far-field earthquakes and consequently rise the hazard of earthquake-caused failure of structures. Despite there are several studies have investigated the seismic behavior of retaining structures, but the researches about retaining walls subjected to the influence of near fault like pulse earthquakes is still not adequate. The current study targets to numerically assess the dynamic performance of concrete cantilever retaining walls during far field ground motions (FFGMs) and near-fault ground motions (NFGMs). The nonlinear analysis of time history is conducted using the finite element method for three cantilever retaining wall models. The results of the analysis gained in terms of top horizontal displacement of the wall, active seismic earth pressure, and acceleration response of the system, which have been considered to recognize the impact of near fault earthquake on retaining structures. Additionally, the influence of different PGA of NF and FF earthquakes has been studied.

In this study, the vehicular air pollution from the Nairobi Expressway corridor was estimated by simulation using AERMOD dispersion model. The Vehicle Kilometer Travelled (VKT), emission factors, and traffic data were used to estimate the pollutants from vehicular traffic.. The highest modelled 24-hour and annual concentrations of PM2.5 were 0.274 µg/m3 and 0.152 µg/m3, whereas the highest 24-hour and annual concentrations of PM10 were 0.405 µg/m3 and 0.225 µg/m3, respectively. The maximum 24-hour and annual concentrations of Total Volatile Organic Compounds (TVOCs) were 20.8 µg/m3 and 11.5 µg/m3, respectively, whereas the maximum 8-hour and annual concentrations of carbon monoxide (CO) were 319 µg/m3 and 177 µg/m3, respectively. The highest modeled 24-hour and annual concentrations of NO2 were 28.2 µg/m3 and 15.7 µg/m3, respectively. The 24-hour average measured TVOCs values showed that Nairobi expressway traffic contributed 3.5 percent to the measured TVOCs concentration value, but CO accounted for 55 percent of the measured value. According to the simulated PM2.5 and PM10 concentration values, Nairobi expressway traffic contributed 1.1 and 1.6 percent, respectively, to the 24-hour average measured concentration levels.

Authors: Dewi Sri Hartati , Thamrin Rendy , Haris Sabril , Yastari Febi Putri
Published: June 2024

Currently, there is not much research on strengthening structural elements with hollows. This manuscript presents the test results from twelve circular reinforced concrete column specimens strengthened with CFRP strips. This study focuses on the strain behavior of longitudinal reinforcement and CFRP strips due to high shear force intensity. Hollows in the cross-section are used to see the effect of voids on the column strain distribution. Nine specimens have a hollow cross-section with hollow diameters of 1.5", 2.5", and 3.5" for each of the three specimens. Meanwhile, the other three specimens have a solid crosssection. All specimens do not use stirrups to determine the contribution of concrete and CFRP strips to resist shear. Strain gauges are placed in certain positions to read the strain on the longitudinal reinforcement and CFRP strips. The test results are in the form of tensile forces and are then analyzed to obtain the movement pattern of tensile forces in the longitudinal reinforcement and CFRP strips. Numerical analysis using a fiber element model is used to obtain the strain in each reinforcement layer. The numerical analysis results were then compared with the test results and showed close results. Then, an equation for calculating the tensile force in CFRP strips is proposed. The proposed equation approximates the test results with an accuracy level of 90%.

Published: June 2024

At present, the need to make use of industrial waste materials is increasing due to their harmful effects on the environment. In the present work, the behavior of hybrid reinforced T-Beam by steel, and CFRP with rubber is studied. The finite element modeling by using ANSYS version 15 program. It contains also all the required steps needed to create the concrete models that were prepared to study the behavior of beams with rubber concrete. The reinforcement of beams was various combinations of polymer CFRP and steel bars. The crumb rubberized concrete mixes were prepared by partial substitution (5 %, 10 %, 15 %, 17.5 %, 20 %, 22.5 %, and 25 % replacements by volume). Due to the large number of parameters affecting the behavior of Hybrid Reinforced T- Beam with rubber concrete, an extensive parametric study was performed using ANSYS version 15 program. Three parameters were investigated namely: Bottom RFT, compressive strength of concrete, and the existence of opening. The analytical results agree well with the experimental results in terms of mode of failure and the failure load values. The results indicated that although the flexural capacity of the tested specimen decreased with the addition of Crumb Rubber and reduced its self-weight. The failure load of the beam increases with bottom reinforcement by the GFRP bar or CFRP bar. Also, reinforced beams by CFRP bars had a higher failure load than reinforced beams by GFRP bars. Having an opening in hybrid reinforced T-Beam with rubber concrete reduced the beam load capacity and maximum deflection. Also, using GFRP bars, and CFRP bars in the vicinity of openings in hybrid reinforced T-Beams increased the load capacity of these beams.

Published: June 2024

Rapid urbanization and population growth in Northern Vietnam have exacerbated in domestic solid waste (DSW), posing environmental challenges. Law on environmental protection (2020) promoting source separation, a disconnect persists between policy and public action. This study addresses this gap by employing a Knowledge, Attitude, and Behavior (KAB) approach to conduct a novel regional analysis of DSW management practices. A stratified random sampling design was utilized, with 1,000 people participating from five different regions of Northern Vietnam: delta rural areas, mountainous rural areas, coastal rural areas, tourism development areas, and urban areas. Data analytic techniques, including descriptive statistics, exploratory factor analysis and multiple regression analysis, were employed to uncover factors that influence DSW management behavior in each location. The research revealed significant regional variations in KAB aspects of DSW services. While positive attitudes towards responsible SWM practices (80% of people) were evident, the number of factors influencing DSW management varied (3-6) across regions. These findings provide valuable insights for policymakers, guiding the development of targeted interventions that align with national law. This paves the way for more effective, regionally-tailored waste management practices in Vietnam.

Authors: Mufeed Abd-al-Ghafoor Lubna , Harba Ibrahim S. I.
Published: June 2024

This study describes an experimental research focusing on the behaviour of Lightweight Aggregate Wide Reinforced Concrete Beams (LAWRCB) using shear steel plates. This technique represents an inexpensive way which reduces structural and building complexities. Wide beams can provide adequate cross-sectional areas to meet the specified capacity in a shallower depth than a system of narrower beams placed similarly in the design. Also, WB treats the crowd of stirrups because the shear component provided by concrete is very small compared with high depth concrete Beams. This research is also trying to minimize the weight of a wide concrete beam using light weight concrete instead of using conventional concrete which has effects on the deflection, crack patterns, and load carrying capacity. This investigation consists of reviewing the previous work and an experimental program consisting of testing mixes to produce lightweight concrete. In addition, several simply supported wide beams with various parametric studies will be designed, cast, and tested. After the specimen tests are carried out, comparisons and discussions of the results will be made with code requirements.

Authors: Bahi Anas , Zerradi Youssef , Bziaz Mohammed , Tlidi Younes , Soufi Amine , Bennouna Rhita , Chakiri Said
Published: June 2024

Geophysical methodologies represent a paramount approach for assessing the mining potential of a given area. Among these methodologies, the magnetic method stands out as indispensable for the exploration of metalliferous deposits. This method facilitates the characterization of both the lateral extent and vertical depth of anomalous bodies within the surveyed region, as discerned from their influence on the total magnetic field. In the case of the manganese-rich mining zone situated in Bouarfa, particularly in Aïn Beida, the mineral deposit genesis typically involves the association of manganese with ferruginous minerals, significantly perturbing the total magnetic field. However, the initial findings necessitate meticulous corrections to isolate the exclusive impact of anomalous bodies on the magnetic field. Accordingly, correction procedures must address diurnal variations prior to executing a Reduction to the Pole (RTP), enabling the identification of well-defined and unipolar anomalies crucial for precise delineation of potentially mineralized zones. Integration of spatially interpolated data yields comprehensive maps delineating areas of mining significance and elucidating pertinent geological phenomena within the study area. Subsequently, employing 2D modeling techniques on magnetic survey results facilitates accurate estimation of mineralized horizon extents and thicknesses. Ultimately, these synthesized maps serve as valuable guides for subsequent mechanical prospecting endeavors aimed at corroborating findings derived from geophysical methodologies.
Flexural Strength of RC Continuous Beams Strengthened by CFRP Using EBR and EBROG Methods: Experimental and Analytical Study
Authors: Qassim Hanan J. , Mashrei Mohammed A.
Published: June 2024

Recently, a new proposed technique named; Externally Bonded Reinforcement on Grooves (EBROG) has been presented as a strengthening method to postpone or eliminate the undesirable debonding failure mode that is accompanying to Externally Bonded Reinforcement (EBR) method. This paper introduces an experimental and analytical study to evaluate the validity and accuracy of the formulas that were introduced by the standard codes and researchers, in estimating the ultimate load of RC continuous beams strengthened with carbon fiber reinforced polymer (CFRP) sheets in flexure. The experimental program includes testing of ten RC beams with cross section of (200×130) mm and two equal spans, each span has a 1050 mm length. The comparison between the ultimate load collected from the test results and that predicted using ten different analytical models is conducted. It is found that the ACI 440.2R-17 and most of other analytical models well predicted the ultimate load of RC beams strengthening with one layer of CFRP sheets using EBR, but most of these models significantly underestimate the ultimate load of tested beams that were strengthened using EBROG method. ACI, Shehata el. al., and Teng et al. models give close predicted load to the experimental results in case of EBR beams strengthened with two layers.

Published: June 2024

Objective

The objective of the study was to explore the connection between peer pressure and academic stress among junior high school students.

Methods

This descriptive correlational study was conducted to investigate the link between perceived peer pressure and academic stress. The study involved a total of 525 adolescents, aged 14–19 years, drawn from 6 public junior high schools (PJHS) in Padang, Indonesia, using purposive sampling. Academic stress and perceived peer pressure were assessed using the Educational Stress Scale for Adolescents (ESSA) and the Perceived Peer Pressure Scale (PPPS).

Results

The findings indicated significant variations in stress levels among students in different grade levels (7th, 8th, and 9th grades) (P < 0.05), while there were no noteworthy differences in peer pressure across these grade levels (P > 0.05). Additionally, there was a positive correlation observed between perceived peer pressure and academic stress (r = 0.14, P < 0.05). Furthermore, multiple regression analyses, incorporating demographic variables and perceived peer pressure as independent factors, yielded statistically significant results (adjusted R

Authors: Frunzeti Teodor , Dumitru Alexandru-Cosmin
Published: June 2024

This article analyses the regulatory framework for virtual currencies in the European Union, tracing the development from several national laws to the comprehensive Markets in Crypto-assets (MiCA) regulation. At first, EU member states had different methods for regulating virtual currencies, creating a fragmented regulatory landscape that posed difficulties for market integrity, consumer protection, and cross-border transactions. This article covers the many regulatory responses before MiCA, explores the reasons for regulatory harmonization, and delves into the legislative process that resulted in the creation and proposal of MiCA. We examine how MiCA tackles the deficiencies of past regulations and its impact on standardizing virtual currency processes throughout the EU. MiCA's importance rests in its ability to provide a cohesive legal structure that harmonizes innovation with the requirements of financial stability and consumer safeguarding. This article explores how MiCA will influence member states' laws and the virtual currency market, providing insight into the future of EU financial regulation in the digital era.

The method of emergence of a technological mathematical system is the process by which complex behaviors are formed starting from extremely simple rules. This process is dynamic, with entities presenting emergence over a longer period of time (for example, the successive stages of evolution of multicellular structures from simple organisms to a human brain capable of consciousness. At the same time, emergence can occur between entities of sizes that differ by many orders of magnitude (for example, the interaction between a large number of neurons resulting in the human brain capable of rational thought, although the neurons themselves do not exhibit this ability.

Authors: Agatowski Adam , Młynarczuk Mariusz
Published: June 2024

For more than a dozen or so years now, there has been growing interest in the use of modern laser scanning measurement methods in numerous mining operations engaged in underground excavation. However, the simple possession of a scanner does not guarantee satisfactory measurement results. This study sets out the results of scanning mine excavations in an active mine and describes the current guidelines on various aspects of the measurement process. These guidelines were developed on the basis of several hundred measurements carried out over the last dozen or so years.

This study also outlines the typical measurements errors observed over the course of many years. These errors, resulting partly from hardware limitations and partly from human error when planning or actually performing measurements, were an important factor behind the introduction of standards regulating underground measurements.

This study discusses in detail not only scanning that utilises traditional stationary laser scanners but also scanning based on mobile scanners. It also presents possible areas of future technological development in line with global trends.
Horizon 2020 Project Analysis by Using Topic Modelling Techniques in the Field of Transport
Authors: Esztergár-Kiss Domokos
Published: June 2024

Understanding the main research directions in transport is crucial to provide useful and relevant insights. The analysis of Horizon 2020, the largest research and innovation framework, has been already realized in a few publications but rarely for the field of transport. Thus, this article is devoted to fill this gap by introducing a novel application of topic modelling techniques, specifically the Latent Dirichlet Allocation (LDA), in the Horizon 2020 framework for transport projects. The method is using the Mallet software with pre-examined code optimizations. As the first step, a corpus is created by collecting 310 project abstracts; afterward, the texts of abstracts are prepared for the LDA analysis by introducing stop words, optimization criteria, the number of words per topics, and the number of topics. The study successfully uncovers the following five main underlying topics: road and traffic safety, aviation and aircraft, mobility and urban transport, maritime industry and shipping, open and real-time data in transport. Besides that, the main trends in transport are identified based on the frequency of words and their occurrence in the corpus. The applied approach maximizes the added value of the Horizon 2020 initiatives by revealing insights that may be overlooked using traditional analysis methods.

Published: June 2024

Objective: This study aimed to investigate the relationship between self-efficacy and academic motivation in Kosovo undergraduate students. It also examined whether the relationship between academic motivation and self-efficacy was significantly mediated by the effect of educational achievement. It also took into account the role of the socio-economic status in this relationship.
 
Theoretical Framework: The rationale of this study was framed within the theoretical framework of self-determination that focuses on the controlled behavior in academic performance and within the theoretical framework of self-efficacy which is based on belief in one's ability to complete specified tasks or goals.
 
Methods: This study used a quantitative methodology by adopting standardized measures including a 27-item survey of academic motivation and a 10-item instrument of self-efficacy. The construct of academic achievement was measured by a self-reported average grade of students and a socio-economic status questionnaire was designed for this purpose of this study. Data collection was carried out online through the online Qualtrics platform.
 
Results and Conclusions: The results showed that there was a statistical significant effect of self-efficacy to both extrinsic and intrinsic motivation. Results revealed that there was no significant correlation between academic achievement and self-efficacy or academic motivation and no significant correlation between the socio-economic status scores and all the variables.
 
Implications of research: The findings of this study have practical implications for university administrators and researchers focused in students’ retention in universities and their academic achievements. It demonstrates that how well students are academically motivated to achieve their academic goal very well depends on their perceived self-efficacy.

Published: June 2024

Objective: The research sought to promote a characterization of the cachaça LPA in Morretes, Paraná in comparison to an LPA in another Brazilian region, whose production is similar and is classified as one of the most developed in Brazil.
 
Theoretical Framework: Studies about Local Productive Arrangements have been relevant to proposals and regional development, so the basis of the research was inserted in the introductory phase.
 
Method: Between May 2022 and February 2023, an exploratory descriptive study was carried out with leaders of two cachaça production arrangements located in the south of Brazil, one consolidated in Santa Catarina and the other one under development in Paraná.
 
Results and Discussion: The results obtained revealed that despite the similar number of producers, the Morretes LPA has a production capacity equivalent to 35% of what is produced in the Luiz Alves LPA. The difference in productivity is not linked to factors such as proximity to the consumer market, distribution logistics, labor or even geoclimatic characteristics. The main factors limiting the easier development of LPAs were the degree of difficulty in regularizing production, the lack of technical assistance and the almost non-existence of public policies, with the Morretes LPA on the coast of Paraná being most impacted. It is concluded that the insertion of tourism associated with beverage consumption, investment in marketing actions and public policies that facilitate the regularization of informal producers can strengthen the Morretes LPA and promote its consolidation as an economic activity that generates regional development.
 
Research Implications: The Morretes LPA has all the favorable and synergistic conditions for the development of the cachaça LPA, and in this context the offer of new services and products arising from production and trade activities can generate a set of entertainment offered as a new experience for tourists, in addition from visits to stills and the creation of parties and fairs with the drink theme.
 
Originality/Value: Comparative studies between local productive arrangements are still little explored in scientific literature and may guide regional development in a more organized way.

Management rights over emergent land on the banks of the Batanghari River Watershed in Penyengat Rendah District, Jambi City have been practiced by the local community for generations without formal ownership as of this study. This article examines the legality of land tenure under Indonesian law and the rights to manage land emerging along the Batanghari riverbanks, aiming to advise the local government on the crucial need for legal recognition of these rights. Utilizing an empirical research method involving direct community engagement, the study finds that community management of this land is driven by longstanding residency and utilization, the scarcity of available land for agriculture in Jambi City supporting the local economy, high land prices, and historical reliance on riverbank land use. Despite continuous management, these activities lack permanent legal status as outlined in Article 16, Paragraph (1) of the Basic Agrarian Law.

A pandemia da Covid-19 ocasionou grandes impactos nas vidas dos indivíduos a em nível global. Em consequência à recomendação do isolamento social, as residências tornaram-se ambientes de longa permanência, fazendo necessária sua adaptação para atender as novas demandas espaciais. Esse cenário influenciou diretamente na interação dos usuários com suas moradias, refletindo no significado do habitar e na experiência do morar, implicando em alterações no estilo de vida que podem impactar na saúde física e mental dos indivíduos. Neste contexto, este artigo mostra resultados de um estudo cujo objetivo foi realizar uma Avaliação Pós-Ocupação (APO) nos ambientes residenciais, na área de conforto ambiental amparado pelas estratégias da neuroarquitetura, com o intuito de entender o espaço físico sob a ótica de seus usuários, visto que, esse espaço físico desempenha um papel fundamental no comportamento, na tomada de decisões e no bem-estar. Para isso, foi disponibilizado para a comunidade um questionário e o instrumento Poema dos Desejos. Desse modo, foram obtidos indicadores positivos de satisfação dos moradores com suas residências, no entanto, os desejos, sintomas e percepções apontadas pelos usuários evidenciam que o ambiente é capaz de prejudicar física e psicologicamente sem que se note. A análise dos resultados indica que o cenário pandêmico evidenciou que o ambiente residencial não é estático, necessitando de transformações conforme as necessidades transitórias, fazendo com que seja necessário (re) pensar a configuração dos espaços, aplicando as estratégias de conforto ambiental e da neuroarquitetura, para que elas possam auxiliar os usuários em suas relações com a moradia, proporcionando saúde e bem-estar.

A própolis é produzida pelas abelhas a partir de diversas origens botânicas e está em expansão de consumo na forma de extrato. Durante a pandemia de COVID-19, os hábitos de consumo do extrato da própolis podem ter mudado, por produto culturalmente veiculado como remédio natural. Para a coleta de dados foi utilizado o método Survey, questionário composto por 17 questões e 227 respondentes. Os dados foram exportados para uma planilha do Excel, onde ocorreu uma análise de distribuição das variáveis qualitativas e quantitativas de cada pergunta selecionada. Verificou-se que 64,3% mulheres e 35,7% homens, faixa etária predominante entre 20 e 29 anos, público heterogêneo em questão de escolaridade e renda, sendo que 86,4% dos participantes eram do estado de São Paulo. Quanto ao nível de escolaridade, 39,3% dos participantes estavam cursando ou tinham pós-graduação; 56% estavam cursando ou tinham graduação completa e 4,7% com ensino médio ou fundamental. Cerca de 185 (81,49%) dos 227 participantes, 185 (81,49%) utilizam o própolis quando estão doentes, principalmente para a dor de garganta (23,9%). Outras razões para o consumo da própolis foram: COVID-19, gripe e resfriado, imunidade e sinusite. Cerca de 21,1% dos participantes aumentaram o consumo de extrato de própolis durante a pandemia.

A Organização Mundial da Saúde estima que doenças periodontais graves afetam cerca de 14% da população adulta global, representando mais de um bilhão de casos no mundo. A doença periodontal (DP) é desencadeada pela resposta imune do hospedeiro contra microrganismos patogênicos do biofilme dental e é caracterizada pela destruição do tecido gengival, osso alveolar e tecidos conjuntivos que sustentam o dente. O biofilme, composto por bactérias, estimula o processo de inflamação local gerado pelo aumento de citocinas, células inflamatórias como macrófagos, células B e T. O equilíbrio entre a virulência do biofilme local e a resposta imune do hospedeiro influenciam na progressão e gravidade da doença periodontal. Diversos fatores e condições sistêmicas podem interferir e modular a resposta do hospedeiro, e a relação entre doença periodontal e doença sistêmica é bidirecional, ou seja, a doença periodontal pode levar a resultados sistêmicos adversos, e certas doenças sistêmicas predispõem os indivíduos à doença periodontal. Existem diversas espécies de patógenos abundantes na cavidade oral, principalmente bactérias anaeróbicas Gram-negativas, que produzem endotoxinas que contribuem diretamente com doenças sistêmicas. Estudos recentes demonstraram possíveis mecanismos pelos quais a periodontite pode aumentar a suscetibilidade a doenças sistêmicas. Esta revisão de literatura buscou apresentar a possível relação da doença periodontal com artrite reumatoide, diabetes mellitus e doenças cardiovasculares por meio de levantamento bibliográfico realizado nas bases de dados: PubMed, PERIÓDICOS CAPES, MEDLINE, LILACS e Biblioteca Virtual em Saúde. Diante dessa pesquisa, pode-se concluir que a doença periodontal e a saúde sistêmica têm uma associação bidirecional.
