Authors: Cairns Joshua Pritchard , de Bragança Pedro Henrique Negreiros , South Josie
Published: July 2024

Background.
This review compiles and synthesises the existing information concerning non-native poecillid introductions to Africa. The recent upsurge in research on invasive poeciliids has revealed their widespread occurrence in Africa.
Results.
Within the 87 relevant articles, 74% reported on the presence Gambusia spp., 33% on P. reticulata, 19% on X. hellerii, 11% on X. maculatus, and 5% on other ornamental poeciliids. Overall, poeciliids have been introduced to 25 different countries in Africa, with Gambusia spp. being introduced to 16 countries and P. reticulata to 19 countries. Our results are representative of the current state of research on invasive poecilids in Africa. In particular there was a concentration of studies in South Africa, with limited research elsewhere. Current distribution data is relatively patchy, although widespread surveys of multiple river systems in Morocco and South Africa, confirmed widespread and abundant established poeciliid populations. The ecological impacts of invasive poeciliids in Africa remain understudied but evidence indicates deleterious effects on native fish, invertebrates, and amphibians, many of which are critically endangered or endemic species.
Conclusion.
An increased effort to monitor species composition in vulnerable waterbodies, especially in the many African countries where invasive poeciliids are reported should be completed and to reveal further established populations. Future research should prioritise quantifying the ecological impacts of invasive poeciliids in the field and identifying both vulnerable and resistant native ecosystems to guide future management decisions.

Published: July 2024

Background
The surge in breast cancer incidence worldwide highlights the urgency of improving diagnostic methods to accurately assess disease progression. This study aimed to elucidate the metabolic characteristics of breast cancer serum and identify differential metabolites for diagnosing breast cancer and assessing its severity, thereby providing a reference for clinical practice.
Methods
Serum samples from patients with benign and malignant breast lesions and healthy subjects were analyzed using GC-MS. OPLS-DA identified key metabolites distinguishing breast cancer from benign lesions and advanced from early-stage cancer. Spearman's ρ revealed correlations between metabolite levels and disease stages, while the AUC demonstrated the discriminatory capability of key metabolites.
Results
Amino acid metabolism was significantly altered in breast cancer patients, particularly in alanine, aspartate, and glutamate metabolism. Glutamic acid and lactic acid levels were significantly elevated in breast cancer patients compared to those with benign masses, while fructose levels were markedly reduced. The AUCs for distinguishing benign lesions from breast cancer using glutamic acid, lactic acid, and fructose were 0.9771, 0.9608, and 1.000, respectively. Comparative metabolomic analysis revealed significant differences between early-stage and late-stage malignant breast lesions. Glutamic acid levels increased progressively from healthy individuals to those with benign tumors, early-stage breast cancer, and advanced cancer, showing a strong positive correlation (ρ = 0.937, P < 0.001) with breast cancer progression, and an AUC of 0.9571 for distinguishing late-stage from early-stage breast cancer.
Conclusions
Our findings demonstrate the relationship between serum metabolite levels and breast cancer occurrence and progression. Further investigations are warranted to elucidate the precise roles of these metabolites.

Authors: Perea Gabriel Ródenas , Esteban Alfonso Pérez , Albéniz Alicia Pérez , Al-Halabí Susana , Pedrero Eduardo Fonseca
Published: July 2024

Background: The transdiagnostic and network model approaches to psychopathology have emerged as an alternative to taxonomic systems. The main goal was to examine the network structure of the transdiagnostic dimensions of emotional disorders in adolescents with subclinical emotional symptoms. In addition, cross-sectional network analyses were conducted to investigate the relationships between transdiagnostic dimensions and socio-emotional adjustment.
Method: The sample consisted of a total of 476 adolescents from 85 schools from different provinces in Spain with subthreshold anxiety and depression. The mean age was 13.77 years (SD = 1.43, range 10 to 18 years), 73.9% were female. Several questionnaires assessing transdiagnostic dimensions of emotional disorders, mental health difficulties, self-esteem, perceived social support, feeling of belonging at school, and prosocial behavior were used.
Results: A strong interrelation was found between the transdiagnostic variables, except with the positive temperament dimension. The dimensions with the greatest weight were those of traumatic reexperiencing, intrusive cognitions, avoidance, neuroticism, and depressed mood. Negative relationships were found between the transdiagnostic variables and the protective factors included in the study. Stability analyses indicated that the networks where accurately estimated.
Conclusion: The present paper points to the value of conceptualizing emotional disorders from a transdiagnostic and network model perspective. In addition, the work provides new insights into the nature of the relationships between transdiagnostic dimensions of emotional disorders, and the role played by risk and protective factors.
A practical approach focused on optimal velocity profiles selection for hybrid stepper motors to maximize available synchronous torque utilization and minimize positioning error in open loop operation, with application to Manufacturing Systems.
Authors: Barros Oscar , Maury Heriberto
Published: July 2024

In this article, the optimization of hybrid stepper motors performance in open loop is approached by movement strategy definition, adjusted to the load dynamics enabling the execution of movements using maximum synchronous torque available and with the minimum positioning error or step loss. A concept known as the equivalent power circuit time constant is proposed. This concept allowed the development of a practical approach to calculate the synchronous Pull-Out torque curves in terms of power control circuit characteristics and stepper motors electrical parameters. By combining this approach with the load characteristics in a dimensionless form, a differential equation is obtained whose solution provides the optimal stepping rate profile and the limits for the kinematic parameters such as maximum speed and minimum acceleration time allowed for synchronous movement. The proposal is validated through experimentation and obtained a low positioning error for exponential profiles compared to other widely used shapes of acceleration. During the project development, a test bench for the drive systems was designed and built. In addition, a case study is presented to show proposed methodology implementation.

Published: July 2024

Invasive alien plants are a major threat to biodiversity and the agricultural economy. The invasive weed (Ammannia coccinea) can compete with rice in paddy fields, posing a potential threat to rice production. Despite the crucial importance of estimating the global geographical distribution and ecological niche dynamics of A. coccinea in order to implement effective early warning and control strategies and to ensure global agro-rice security, there has been a dearth of relevant research. This study employed biomod2 ensemble model based on environmental and species data to analyze the distribution range shift and ecological niche dynamics of A. coccinea under the current and future climate scenarios. The results showed that the potential suitability area of A. coccinea was mainly located in Southern North America, northern and south-eastern South America, south-western Europe, the Middle East, central Africa, western Asia, south-eastern Asia, with a gradual increase in the mid-high suitability habitat areas with time and radiation levels. Under future climate change scenarios, the centroid of the suitable area of A. coccinea may shift northwards to higher latitudes. The ecological niche of A. coccinea has shifted less and the overall ecological niche has maintained stability under different climate scenarios in the future compared to the current period. Temperature, precipitation, and the human impact index were the primary factors influencing the future distribution of A. coccinea. In conclusion, climate change was contributing to the expansion of A. coccinea's high habitability area and shifts its ecological niche, necessitating the implementation of effective transnational management strategies to mitigate the impact of this invasive species on rice production.
Development of Composite Index in Psychiatry Clinical Trial
Authors: Zhang Haiqi , Chow Shein-Chung
Published: July 2024

In psychiatry clinical trials, a validated instrument (or questionnaire) which consists of a number of questions (or items) is often used for evaluation of the safety and efficacy of a test treatment under investigation. This approach based on rating scales for evaluation of safety and efficacy of a test treatment under study, however, has been criticized of being subjective. To overcome the problem, the use of a composite index which combines the subjective rating scales and objective functional magnetic resonance imaging (fMRI) is proposed. For this purpose, statistical methods for development of composite index are derived. The proposed composite index is evaluated both theoretically and via extensive clinical simulation studies.

Authors: BHAVANI CHALADI S GANGA , PRASAD N BHANU , KISHORE D RAVI
Published: July 2024

As microgrids (MGs) deploy stability and continuous power flow in utility grids it acts as a remedial measure for power grid failure and high load demand. A hybrid Renewable Energy Source (RES) fed microgrid with an Adaptive Neuro fuzzy Inference System (ANFIS) controller is suggested. The photovoltaic (PV) system and Doubly Fed Induction Generator fed Wind Turbines (DFIG-WT) are selected as a typical RES. Among various converters in use, a novel high gain Landsman converter is utilized to attain consistent DC-link voltage and to boost the photovoltaic output for the generation of high efficiency outputs. ANFIS method, which is a significant alternative designed with the combination of two computing approaches of fuzzy logic and Artificial Neural Network (ANN) is used for the converter control. To increase the convergence rate and reliability prediction rate, the constraints of ANFIS are improved using Crow Search Algorithm (CSA). Subsequently, the wind system with Pulse Width Modulation (PWM) rectifier regulated by Proportional Integral (PI) controller is connected to the microgrid setup. A battery energy storage system (BESS) is adopted for the storage of energy during surplus conditions while providing energy to DC link at times of power shortage from PV and wind sources. Assessments on the control scheme are simulated in MATLAB platform. The comparison analysis for voltage gain as well as efficiency for the proposed converter and conventional converters are analyzed and the proposed high gain Landsman converter exhibits 97% efficiency in boosting the DC voltage.
NADPH-mediated in-situ formation of gold nanoparticles for the enzymatic determination of atropine
Authors: Domínguez Mario , de Marcos Susana , Galbán Javier
Published: July 2024

In this work, it has been demonstrated that the formation of gold or gold-platinum nanoparticles mediated by a NADPH-dependent enzymatic reaction can be coupled to the determination of atropine. First, the formation of AuNPs and AuPtNPs from Au(III) and NADPH was studied and characterised using TEM techniques. It has also been observed that reducing properties of NADPH and NADH lead to different nanoparticle yields, which could be used to differentiate between the two cofactors. Based on these results, the method was coupled to the enzymatic determination of atropine using tropinone reductase and NADPH, since the absorption band at 550 nm (plasmon band) of the formed AuNPs can be related to the concentration of atropine in the range from 0.025 mM to 0.09 mM with an RSD of 3% (n = 5). The method has been applied to the determination of atropine in buckwheat with good results.
Utilizing the biosimulator to analyze the environmental microbiome within the intensive care units of a hospital
Authors: Thomas Sunil , Bittinger Kyle , Livornese Lawrence L.
Published: July 2024

In our previous study, we demonstrated the ability of an engraved Petri dish, referred to as a "biosimulator," to induce adhesion of non-adherent cells and the microbiome. This paper delves into the utilization of this innovative biosimulator to elucidate the microbiome composition within intensive care units (ICUs) in a hospital setting. The biosimulator, containing a nutrient-rich bacterial growth medium, was strategically placed in various locations within ICUs for a 24-hour period, followed by an incubation period of three days under both aerobic and anaerobic conditions to simulate the diverse environmental niches within the ICUs. By employing 16S rRNA profiling, we meticulously sequenced the microbiome present in the ICU samples. Our findings revealed that the microbiome composition within ICUs closely mirrored that of the patients occupying the facility. Furthermore, the microorganisms thriving within the ICU environment exhibited notably closer interrelationships compared to those observed under control conditions. This study underscores the potential of our biosimulator approach as a valuable tool for comprehensively characterizing and understanding the microbiome dynamics within healthcare environments, particularly in high-risk settings such as ICUs.
Von der (normativen) Idee zur (pädagogischen) Praxis
Authors: Otto Daniel
Published: July 2024

Der vorliegende Beitrag betrachtet die Genese von OER seit deren Initiierung im Jahr 2002. Gerade Deutschland war lange Zeit kaum an der Entwicklung und Verbreitung von OER beteiligt. Jedoch haben OER durch verschiedene Massnahmen vor allem in der vergangenen Dekade in Deutschland an Bedeutung gewonnen. Der Beitrag zeichnet diese Entwicklung aus der Perspektive einer gestaltungsorientierten Mediendidaktik nach. Während die Entstehungsphase primär durch eine OER-Gemeinschaft geprägt war, erfolgt mittlerweile eine zunehmende strukturelle Verankerung von OER in der Hochschule. Die wissenschaftliche Auseinandersetzung mit OER hat sich primär mit den Gründen und Hindernissen für deren Nutzung befasst. Hierdurch konnten wichtige Erkenntnisse, auch für die weitere Förderung von OER, gewonnen werden. Dennoch existieren Missverständnisse über OER, die sich auch durch eine grundlegendere Problematik der Ausrichtung der empirischen Bildungsforschung erklären lassen. Die Förderung von OER sollte weniger aufgrund von Wirkungserwartung für die Hochschule per se erfolgen, sondern als ein Potenzial verstanden werden, mit dem die Transformation von Hochschule und einer Bildung in der digitalen Welt gelingen kann. Dafür, so die These, ist eine pragmatische Haltung erforderlich. Dies könnte bedeuten, die anfangs wichtige und immer noch einflussreiche Bottom-up-Perspektive um eine Top-down-Perspektive zu erweitern, die strukturelle Massnahmen adressiert, um die mittel- und langfristige Förderung von OER sicherzustellen.
Digitale Barrierefreiheit im Kontext von OER exemplarisch anhand des InDigO-Projekts
Authors: Otten Nicole
Published: July 2024

Digitale Barrierefreiheit ist in internationalen und nationalen Gesetzen einschliesslich der UN-Behindertenrechtskonvention und des Bundesgleichstellungsgesetzes in Deutschland verankert. Trotz ihrer Konnotation zu Menschen mit Behinderungen, ist digitale Barrierefreiheit für alle Menschen in verschiedenen Situationen von Vorteil. Die Berücksichtigung der Prinzipien digitaler Barrierefreiheit ist zudem von grundlegender Bedeutung für inklusive Bildung. So spielt die digitale Barrierefreiheit sowohl in der Gestaltung von OER als auch bei der Umsetzung von OER-Plattformen, um gleichberechtigte Teilhabe an Medien und Kommunikation zu gewährleisten, eine entscheidende Rolle. OER können in diesem Zusammenhang nicht nur den freien, sondern auch den barrierefreien Zugang zu Bildungsinhalten ermöglichen. Dafür muss jedoch der Verbund aus OER-Material und dessen Aufbereitung sowie auch die jeweilige (OER-)Plattform digital barrierefrei zugänglich sein: Digital barrierefreie OER allein fördern die Teilhabe an Bildung von Menschen mit unterschiedlichen Fähigkeiten und Bedürfnissen nicht. Dieser Beitrag erläutert mithilfe eines entwickelten Modells, wie ein umfassend digital barrierefreier Zugang zu OER geschaffen werden kann, und betrachtet exemplarisch barrierefreiheitsbezogene Bestrebungen des InDigO-Projektes.

Authors: Zugliani Luiz Fernando
Published: July 2024

Objetivo: A finalidade da pesquisa é analisar componentes do sistema de governança e gestão de uma organização sem fins lucrativos, o Instituto de Desenvolvimento e Gestão (IDG), responsável pela gestão de instituições culturais em Pernambuco e no Rio de Janeiro, no contexto do modelo das Organizações Sociais (OS’s) introduzido pela reforma gerencial de 1995.
 Método: Quanto à abordagem, optei pela vertente qualitativa, via pesquisas bibliográfica e documental. Tratando-se de um estudo de caso, busco examinar, em detalhes, o ambiente institucional, na tentativa de oferecer soluções à luz das boas práticas de governança.
Resultados: A par da complexidade dessa configuração organizacional, que mistura trilhas de perfil público e privado, verifiquei que, por estar atrelado a prescrições emanadas das diferentes plataformas legais que orientam os respectivos contratos de gestão, a obrigatoriedade de respeitar as especificidades de cada uma delas cria problemas a uma visão mais geral da entidade, com disfunções no sistema de governança e gestão.
 Originalidade/Relevância: Integrante de um campo específico do Terceiro Setor, e muito pouco explorado, as Organizações Sociais demandam estudos e pesquisas urgentes. Isso porque movimentam bilhões de reais em várias localidades da federação, substituindo o Estado na gestão de serviços públicos relevantes.
Contribuições teóricas/metodológicas: Baseado na literatura e referenciais consagrados, os achados apontam para a criação de uma base empírica a impulsionar uma produção científica até então bem tímida.
 Contribuições sociais/gestão: Ao se identificar fragilidades substantivas no sistema de governança do IDG, a intenção é aduzir caminhos possíveis à melhoria da gestão e, consequentemente, dos serviços públicos prestados aos cidadãos.

Authors: Steelyana Evi , WawoRuntu Ine
Published: July 2024

The research explored an interesting relationship between Indonesian cultural heritage and international relations. It focused on Batik Indonesia and Tenun Endek Bali as strategic tools for cultural diplomacy efforts across different presidential administrations. Starting with President Soeharto’s use of Batik as a gift at the United Nations in the 1980s, these textiles have appeared at six major ASEAN and APEC Summits. The key research question was whether these gorgeous textiles had been effective in promoting Indonesian culture on a global stage. The research aimed to analyze the evolution of Batik Indonesia and Tenun Endek Bali, emphasizing significant international events where they gained recognition, such as the ASEAN and APEC Summits. The research applied a qualitative method and archival content to analyze the journey of batik and Tenun Endek Bali in Indonesian diplomacy. The findings present a compelling narrative. The research suggests a potential link between the use of batik and Tenun Endek and positive outcomes at global meetings, including free trade (APEC 1994), regional cooperation (ASEAN Summit 2011), and consensus building (G20 2023). This highlights Indonesia’s evolving role on the international stage. The research offers a fresh perspective by examining the long-term use of batik and Tenun Endek Bali by Indonesian presidents as cultural diplomacy tools at global events, proposing a novel link to positive outcomes, and highlighting cultural heritage’s potential as a ‘soft power’ diplomatic strategy.

Synthesizing Jakarta City’s Local Wisdom: Reimagining Sidewalks with an Emotional Design and Sustainability Approach
Authors: Limano Ferric
Published: July 2024

The research objective was to design sidewalks as walking facilities and public spaces, considering comfort, safety, cleanliness, and functionality for Jakarta’s residents. The city of Jakarta, as a megapolitan center, hosted various societal activities. The high mobility of Jakarta’s population led to busy sidewalk activities, especially walking, regulated by the Director General of Highways’ guidelines. Walking could help reduce pollution, with Jakarta having the worst pollution in 2023. The research problem, based on 360-degree Google Maps images of sidewalks, was that sidewalks serve not only as footpaths but also as public gathering spaces. The qualitative research method examined digital data on sidewalk use in Jakarta (west, central, south, east, and north). The design process incorporated emotional design (visceral, behavioral, reflective) and three dimensions of sustainability (The Overlapping Spheres Model of Triple Bottom Line/TBL). The result is a 3D sidewalk model using emotional and sustainability design approaches. Synthesis of emotional design interprets visceral (sensory), behavioral (habits), and reflective (values) levels. Synthesis of sustainability includes environmental, social, and economic dimensions, focusing on air quality, water management, and energy efficiency. Social and economic aspects aim to meet Jakarta residents’ basic needs. Ultimately, these recommendations aim to make cities and neighborhoods inclusive, safe, resilient, and sustainable. However, the research is limited to design recommendations without direct implementation. Further research or implementation is needed to address these challenges and ensure Jakarta residents’ future well-being.

Published: July 2024

Increasingly severe flooding seriously threatens urban safety. A scientific urban flood-bearing vulnerability assessment model is significant to improve urban risk management capacity. The gray target model (GTM) has advantages in urban flood-bearing vulnerability assessment. However, indicator correlation and single bull's-eye are commonly neglected, leading to defective evaluation results. By integrating the four base weights, an improved weighting method based on the moment estimate was proposed. Then, the marginal distance was used to quantify the indicator correlation, and the TOPSIS model was introduced to define the relative bull's-eye distance. Thus, an improved gray target evaluation method was established. Finally, an urban flood-bearing vulnerability evaluation model was presented based on the moment estimate weighting-improved GTM. In this study, Zhengzhou City, China, was taken as an example. The spatial and temporal changing characteristics of the flood-bearing vulnerability of Zhengzhou from 2006 to 2020 were investigated. The results show that: (1) On the temporal scale, the disaster-bearing vulnerability of Zhengzhou City showed an upward trend during the 15 years; (2) On the spatial scale, Guancheng District of Zhengzhou City had the relatively highest vulnerability to urban flooding. This study is expected to provide a scientific reference for urban flood risk management.

Authors: Kamravamanesh Donya , Kokko Marika
Published: July 2024

Anaerobic co-digestion of source-separated blackwater (BW) and food and kitchen waste (FW) offers decentralized circular economy solutions by enabling local production of biogas and nutrient-rich byproducts. In this study, a 2 m3 pilot-scale continuously stirred tank reactor (CSTR) operated under mesophilic conditions was utilized for co-digestion of BW and FW. The process obtained a CH4 yield of 0.7 ± 0.2 m3/kg influent-volatile solid (VS), reaching a maximum yield of 1.1 ± 0.1 m3/kg influent-VS, with an average organic loading rate of 0.6 ± 0.1 kg-VS/m3/d and HRT of 25 days. The CH4 production rate averaged 0.4 ± 0.1 m3/m3/d, peaking at 0.6 ± 0.1 m3/m3/d. Treatment of digestate through flocculation followed by sedimentation recovered over 90% of ammonium nitrogen and potassium, and 80–85% of total phosphorus in the liquid fraction. This nutrient-rich liquid was used to cultivate Chlorella vulgaris, achieving a biomass concentration of 1.2 ± 0.1 g/L and 85 ± 3% and 78 ± 5% ammonium nitrogen and phosphorus removal efficiency, respectively. These findings not only highlight the feasibility of anaerobic co-digestion of source-separated BW and FW in local biogas production but also demonstrate the potential of microalgae cultivation as a sustainable approach to converting digestate into nutrient-rich algae biomass.

Introduction:

Obesity has become a pressing global health crisis, reaching alarming
proportions and bearing significant consequences for public health on a global scale.

Aim:

In this research, chitosan nanoparticles were employed to encapsulate ginger extract, and the
impact of this formulation on lipid metabolism and obesity was investigated using a rat model.

Methods:

In vitro experiments, encompassing assessments of cell viability, microstructure, anti-inflammatory
activity, and release dynamics, were conducted to comprehensively evaluate the nanoformulation.
The study extended to examining the potential anti-obesity efficacy of the developed
nanoformulation in rats induced with obesity through a high-fat diet.

Results:

In vitro findings affirmed the safety of the carriers and revealed their robust anti-inflammatory
properties. The average particle size for ginger-loaded and ginger-free chitosan nanoparticles
was measured to be 458.92 ± 139.35 nm and 466.29 ± 142.71 nm, respectively. The in vivo investigation
demonstrated the dose-dependent effects of ginger extract-loaded chitosan nanoparticles,
manifesting in a reduction of obesity and improvement in liver function.

Conclusion:

These promising results suggest that the developed nanoformulation could be considered
a viable therapeutic option for individuals struggling with obesity.
Co2(CO)8 as a CO-source for Pd-catalyzed Carbonylations: An Update
Authors: Das Debarati , Bhanage Bhalchandra Mahadeo
Published: July 2024

Palladium-catalyzed carbonylative cross-coupling reactions with various carbon monoxide (CO) sources cultivate competent routes for the synthesis of bulk and value-added chemicals. However, the practical use of this odorless, inflammable, lethal gas has always raised a concern for chemists. The attention and advancement of various CO-surrogates is surely wel-comed as a green alternative to CO-gas. However, the main concern lies in the suitability and scalability of these CO-surrogate-driven reactions. Literature showed the progress of various ways to make in-situ CO from these CO surrogates. One of the most convenient sources is using metal carbonyls which are already known to lose CO easily. Among all the kinds, Mo(CO)6 gained much popularity but its toxic nature and demand for high temperatures restricted its use. However, Co2(CO)8 is popular as a catalyst but as an in-situ CO-source reports are scarce. This low-melting CO-releaser was found effective in flourishing aminocarbonylation, alkoxycar-bonylation, and reductive carbonylation under mild conditions. This mini-review portrays the recent developments of palladium-catalyzed carbonylation reactions using Co2(CO)8 as a CO source.

elimination half-life of 4.4 ± 1.3 h and has a narrow absorption window. So, this work aimed to
prepare a gastro-retentive floating matrix tablet.

Methods:

The direct compression method was used to manufacture tablets. 32 factorial design
was applied for optimization, taking Hydroxypropyl Methylcellulose K100M (HPMC K 100M)
and the amount of sodium bicarbonate as independent factors and cumulative percentage release
at 1 h, at 6 h, and at 12 h and floating lag time as dependent variables.

Results:

The high amount of HPMC K100M and sodium bicarbonate shows good results. The
optimized preparation was evaluated for differential scanning calorimetry, in-vivo gastric retention in male albino rabbits, kinetic modeling, and stability study. An in vivo study revealed gastric retention of tablets up to 6 h in healthy male Albino rabbits. The stability study indicated no
significant change in the buoyancy and release profiles of the drug.

Conclusion:

From this study, it can be concluded that the gastro-retentive diltiazem hydrochloride floating matrix tablet was successfully prepared and retained inside the rabbit stomach for
up to 6 h and was stable under accelerated stability study

Authors: Almurayh Abdullah , Bedaiwy Abdelrahman , Elsharkasy Ahmed
Published: July 2024

Background

A traffic and speed enforcement system in the Kingdom of Saudi Arabia known as Saher employs traffic monitoring and speed enforcement around the clock using surveillance cameras. Vehicle drivers' attitudes towards this system vary due to several variables.

Objective

The study investigates the impact on the prediction of male vehicle drivers’ orientation towards the application of the Saher system and whether there is a difference in the vehicle drivers’ orientation toward the system over time (five years later).

Methods

The study sample consisted of 761 participants from Imam Abdulrahman bin Faisal University. The quantitative approach was a questionnaire titled “Vehicle Drivers’ Orientation towards the Application of the Traffic and Speed Enforcement Surveillance System (Saher)”, which was applied in 2016 and 2021.

Results

The psychometric characteristics of the study tool were ascertained, the data was quantitatively analyzed, and the results showed that vehicle drivers’ orientations toward the Saher system were positive, the nationality and number and type of violation contribute to predicting their orientation toward the system at varying rates, and the orientation of vehicle drivers toward the system improved five years later.

Conclusion

The study recommends conducting a study with wider societal segments, including women who started driving in Saudi Arabia in 2018, while also focusing on the qualitative aspect of the analysis of the study findings, taking testimonials of the groups that have been involved in accidents and families of groups who have suffered from deaths in order to determine their orientations towards the system.

Authors: Farhan Khatib Zada , Shihata Ayman Sabry , Abubakar Adams Balade
Published: July 2024

Over the past decade, developing geopolymer mixes to replace ordinary Portland Cement (OPC) composites has yielded positive results, leading to extensive research. The incorporation of fibers in geopolymers, besides impacting the mechanical properties, has also significantly impacted durability, mainly when dealing with the most pernicious forms of deterioration resulting from chloride attack, water penetration, sulfate attack, acid attack, as well as freeze-thaw, which occurred through chemical transgression. This study presents a systematic approach to thoroughly review the durability properties of fibrous geopolymer composites exposed to harmful chemicals and extreme environmental conditions. The multi-parameters and factors critically influencing fibrous geopolymers' physical and chemical stability are examined. The study is further aimed at providing an update on the research work undertaken to assess the impact of fiber incorporation on the durability of geopolymer and alkali-activated composites thus far. Furthermore, this review hopes to promote and facilitate research on durability for the long-term, large-scale adoption, and commercialization of advanced fibrous, non-OPC-based materials.
