Authors: Tarafder Md Tanvir Rahman , Mohiuddin Arafath Bin , Ahmed Nisher , Shihab Md Abu , Kabir Md Farhad
Published: November 2024

Resource allocation inside the cloud infrastructure is an essential requirement for better performance and cost-effectiveness. With workloads growing so much more complex and dynamic, we now need automated solutions that allow us to move past tedious, manual resource management. AI provides a unique paradigm for optimizing resource allocation in such complex and dynamic environments. In this paper, we have compared various AI techniques such as machine learning, evolutionary algorithms and deep reinforcement learning for the problem of resource allocation in cloud infrastructure. We analyze their effectiveness for dynamic resource provisioning to satisfy performance objectives while reducing operational expenditure. We offer an in-depth performance comparison using real-world datasets and simulations to showcase the merits and drawbacks of each. Implications: We believe that our findings can offer guidelines to cloud providers, researchers, and practitioners who are interested in making proactive improvements on managing cloud infrastructures using intelligent resource allocation techniques.

This study aimed to explore students’ acceptance of ChatGPT as an assisting tool in academic writing among ESL undergraduate students. ChatGPT is a well-known AI tool with capabilities for language translation, writing drafts, and instant feedback and has effectively helped students improve their English language skills, particularly writing. While ChatGPT has demonstrated great acceptance in writing among EFL students, little is known about ESL students’ acceptance of this tool in their academic writing. This study adopted Technology Acceptance Model (TAM) to discover students’ perceived usefulness, perceived ease of use, attitudes, behavioral intention to use, and actual system usage of ChatGPT. Employing a quantitative approach and descriptive cross-sectional survey design, a structured questionnaire consisting of 24 questions was distributed online to ESL undergraduate students studying at one public university in Malaysia. This study collected 80 completed responses, and the data was analysed using descriptive and inferential statistics. The findings revealed that ESL undergraduate students highly perceived ChatGPT as useful and easy to use in academic writing. Students also expressed positive attitudes towards ChatGPT, high intention to use ChatGPT, and high actual ChatGPT usage in their academic writing. This study concluded that the ESL undergraduate students strongly accepted ChatGPT as a tool in their academic writing, and attitudes were the prominent factor predicting their acceptance of ChatGPT. These findings offer ESL students an understanding of ChatGPT’s potential in writing and help them leverage it to overcome academic writing difficulties.

Authors: Mlungisi Moyo , Stephen Hahlani Onismo
Published: November 2024

Most African systems of education seem to be struggling to prepare students to be successful workers, creators of employment, and even active citizens. This is attributed to the former colonial educational policies and practices inherited into the system. Thus, our African heritage has become vulnerable and hence the need for a total revamp of classroom pedagogies at all levels. It is prudent to acknowledge that immeasurable knowledge imbedded in our African heritage is an empowerment tool that has to be harnessed for sustainable development. Embracing heritage knowledge systems at all levels will inform viable education policies and practices resulting in the need to re-position the twenty-first century classroom teacher. This theoretical paper focused on teacher education and pedagogy as key components for quality education and fulfillment of Education 5.0. It is inevitable therefore for teacher education curriculum to prepare teachers that are practical-oriented and who will appreciate the background and history of the communities where learners come from. The following questions guided findings and conclusions in this paper. (a) What is the role of the twenty-first century teachers in embracing heritage-based education? (b) How can the twenty-first century teacher embrace on heritage-based education for sustainable development? The paper proposes a teacher education curriculum that exposes trainee teachers to the significant pillars of our heritage as a nation. Pedagogy that harnesses contemporary technologies and heritage-based knowledge systems should be the guiding principles in teaching and learning.

Published: November 2024

The internal Shariah audit has emerged as an important means of ensuring that Islamic Financial Institutions (IFIs) act in accordance with the principles of Shariah. Thus, this paper explores the pivotal role of internal Shariah audits in identifying non-Shariah compliance within the IFIs. While the Islamic finance industry continues to expand and diversify, weaknesses in compliance with Shariah standards remain significant concerns as they may erode the confidence of stakeholders and challenge the legitimacy of the industry. This research is therefore informed by the need to improve the efficiency of internal Shariah audits in averting compliance related risks and encouraging sound governance within IFIs. Consequently, this paper focuses on the methodologies and practices of internal Shariah auditors to determine the existing flaws and develop recommendations for enhancing the current audit approaches. The analysis is based on the assessment of the current state of internal Shariah audit practices, key problems observed by the auditors, and suggestions for improving the compliance assurance level. These findings are expected to facilitate the improvement of internal Shariah audit in IFIs and thus help enhance the confidence in the Shariah compliance of these institutions.

Authors: Pal Umapada , Halder Arnab , Shivakumara Palaiahnakote , Blumenstein Michael
Published: November 2024

Detecting and recognizing text in natural scene images and videos is vital for several real-world applications, such as in the analysis of Crime scene CCTV footage, sports videos, and autonomous driving, to name a few. Therefore, one can expect several challenges, namely arbitrarily oriented and shaped text detection and identification in movies and natural environments. Many methods have been developed in the past to address these challenges, including advanced deep-learning models and transformers. Due to several methods available in the literature, it is not so easy to understand the open challenges, applications, directions, scope, limitations, and weaknesses of the methods. Therefore, there is a need to write a survey/review to highlight and discuss the strengths and weaknesses of the developed methods. This survey/review presents different categories of work and discusses their importance, limitations, new challenges, applications, and, finally, directions such that readers can choose appropriate methods and directions to carry out research work in the field of text detection/recognition in the natural scene and videos.

Investigation of the Electrochemical Methylene Orange Effluent Degradation Using Graphite Battery Waste and Seawater
Authors: Gunawan Gunawan , Adiwibawa Prasetya Nor Basid , Wijaya Roni Adi
Published: November 2024

Electrochemical degradation using seawater and graphite electrodes from waste batteries for methylene orange (MO) dye degradation has been successfully carried out. Electrode characterization, electrolyte calibration, and dye degradation effectiveness with various voltages, pH, kinetics, and degradation reaction mechanisms were observed. Characterization showed a characteristic 2θ peak by X-ray diffractometer (XRD) at 26.5 °, and scanning electron microscopy-energy dispersive X-ray spectrometer (SEM-EDX) showed the morphology of hollow grains with carbon (C) and oxygen (O) composition. In addition, scanning potentiometry showed the initiation of hypochlorite compound formation and MO degradation. Further study of degradation effectiveness showed optimal results at 3 volts and above voltages. Hypochlorous acid (HOCl) and hypochlorite ions (OCl-) from seawater are very effective oxidizing agents in acidic conditions compared to other pH conditions. Pseudo-first-order kinetics regulate the electron attack from the hypochlorite oxidizer (OCl-), the hydroxyl groups (•OH) from the seawater electrolysis mechanism with graphite electrode media on the reactive groups, the ring binding on MO, and the degradation. This indicates that the graphite electrode system used to reuse waste batteries and seawater has the potential to degrade waste dyes in aquatic environments.

Filling a gap in Eastern European fashion studies, this book presents middle-class women consuming fashion in the symbolic ‘Little Paris’ of interwar Bucharest, and examines how their material and cultural means supported the city’s modernisation.

Combining archival research with personal archaeology, this interdisciplinary work explores Romania’s reinvention as a modern state, focusing on middle-class women as they lived their lives - walking through the streets, at lavish events, at cafes and clubs, shopping, and working. Analysing largely unseen, unused written and visual texts,The Women of 'Little Paris'encourages exploration of new avenues for research, uniting scholars of Romanian culture, history and fashion and guiding readers through a forgotten, little explored world and, in so doing, adds to our understanding and knowledge of the global image of interwar fashion cultures and the emerging field of Romanian fashion studies.
Taming EdTech
Authors: Hillman Velislava
Published: November 2024

As education becomes more dependent on data-intensive algorithmic systems, private corporate power continues to grow. Left unregulated, the implications for children’s basic rights and future life chances are not to be underestimated.

In this book, Velislava Hillman argues that datafication, i.e. turning all human actions into data, and surveillance have been normalised in eductional settings and shows how edtech products are not improving education equally for all children. She calls for a licensing regime which drives the edtech industry towards ethical practices and meeting appropriate standards before they are allowed to operate in schools. Looking beyond edtech’s potentials, this book outlines a governance framework across socio-technical, ethical, critical pedagogic, and human rights imperatives for governing the digitisation of education.

Wärmespeicherung in Kugelschüttungen bei Temperaturen bis zu 1000K
Authors: Szambien Daniel Felix
Published: November 2024

Die Speicherung thermischer Energie birgt ein beträchtliches Potenzial für die Nutzung von Abwärme und kann auch dazu beitragen, die Energiewende durch die Speicherung von Überschussstrom voranzutreiben. Um sensible Wärme effizient zu speichern, sind hohe Temperaturen von entscheidender Bedeutung. Schüttungen eignen sich hierfür besonders gut, da viele verfügbare Materialien temperaturbeständig und leicht zu beschaffen sind. Allerdings kann die Beschreibung der Wärmetransportprozesse in Schüttungen sehr komplex sein. Nur wenige Untersuchungen befassen sich grundlegend mit diesen Transportprozessen im Zusammenhang mit der Wärmespeicherung und den damit verbundenen hohen Temperaturen. Das Ziel dieser Arbeit ist daher, eine anwendungsorientierte Modellierung von Wärmespeichern mit tiefergehenden Untersuchungen zu verknüpfen und Lösungsansätze vorzuschlagen. Hierfür werden Modelle entwickelt, die die Schüttungsgeometrie, die Strömung und den Wärmeübergang in Schüttungen sowie das thermodynamische Zeitverhalten darstellen und in einen Gesamtzusammenhang gebracht. Um die Ergebnisse der teilweise sehr rechenintensiven Modelle praktisch anwendbar zu machen, wird ein vereinheitlichender modifizierter Ansatz für eine Nu-Korrelation zur Charakterisierung des mittleren Wärmeübergangs zwischen Partikel und Fluid vorgeschlagen. Zur Validierung der entwickelten Modelle wurden Messungen an einem eigens dafür entwickelten Prüfstand bei Temperaturen von bis zu 1000K durchgeführt.
Modellierung von textil-Fördergutverbindungen
Authors: Riemer Patrick
Published: November 2024

Fördergurtanlagen erreichen Achsabstände von mehreren Kilometern. Aus logistischen Gründen wird der Fördergurt in einzelnen Segmenten zur Anlage transportiert und erst vor Ort miteinander verbunden. Diese Verbindungen stellen den schwächsten Punkt eines Fördergurtes dar, da innerhalb einer Verbindungsstelle die Zugkräfte über Scherkräfte im Zwischengummi übertragen werden. Die optimale Auslegung einer Verbindung ist daher essenziell, um die Lebensdauer des Gurtes und damit die Laufzeit der Anlage zu erhöhen. Im Rahmen dieser Arbeit wird ein Verfahren zur Modellierung und Untersuchung von Textil-Fördergurtverbindungen aufgezeigt und validiert. Hierbei werden sowohl Stufenverbindungen als auch Fingerverbindungen betrachtet. Die Modellierung mithilfe der Finiten-Elemente-Methode basiert auf experimentellen Materialuntersuchungen im Labormaßstab sowie der theoretischen Analyse des Kraftübertragungsverhaltens innerhalb der Verbindungen. Die experimentellen und theoretischen Annahmen werden anhand von durchgeführten Prüfungen kompletter Verbindungsproben auf den Gurtprüfständen am Institut für Transport- und Automatisierungstechnik validiert.

Authors: Reitz Birger
Published: November 2024

Die steigenden Datenmengen in gesellschaftlichen und industriellen Anwendungen erfordern neue, innovative Ansätze für die Datenübertragung. Zusätzlich bedarf die Entwicklung von elektrischen hin zu elektrooptischen oder sogar rein optischen Systemen neuartige Fertigungsmethoden und Prozesse, um die anfallenden Daten sicher übertragen und verarbeiten zu können. Glas erweist sich aufgrund seiner Eigenschaften als ideales Trägermaterial für diese Herausforderungen. Mit dem LIDE (engl. Laser induced deep etching) Prozess lässt sich Glas hochpräzise bearbeiten. Durch eine Kombination aus diesem subtraktiven und einem nachgelagerten additiven Verfahren lassen sich integrierte Lichtwellenleiter herstellen, welche in dieser Arbeit sowohl geometrisch als auch optisch charakterisiert werden. Die multimodalen Lichtwellenleiter erreichen optische Dämpfungswerte von 0,258 dB/cm. Zusätzlich werden zueinander kompatible diskrete optoelektrischen Bauelemente ausgewählt und Montagekonzepte sowie Kontaktierverfahren untersucht. Des Weiteren wird der Einfluss des Positionierversatzes zwischen zwei optischen Elementen analysiert, um eine optimale Koppeleffizienz zu gewährleisten. Abschließend werden praxisnahe Anwendungen für die neuartig gefertigten Lichtwellenleitern sowie optimierungspotenziale aufgezeigt und bewertet.

This study will focus not only on the manufacturing sector but also on the service sector. Thus, our research work significantly contributes to the literature and aids in the decision- making process of managers, experts, and government personnel engaged in this field.
GLOBAL CATALYSTS OF CHANGE IN STRATEGIC MANAGEMENT DOCTRINE: RECOGNIZING THE CUMULATIVE IMPACT OF DEGLOBALIZATION, GEOPOLITICL TRIBALISM, AND SOCIAL MEDIA ACTIVISM ON THE RISE OF HYPER-RISK MANAGEMENT
Authors: Cory Kenneth
Published: November 2024

The practice of strategic management has quietly but dramatically changed in the last twenty years. Three global, macro trends are examined in detail which, when added to existing Sarbanes-Oxley regulations, are interacting to create an unprecedented hyper-risk environment. The three macro trends include changes in long-term risks associated with the emergence of an alternative path of globalization, medium-term risks due to the recent rise of the nationalistic populism movement, and nearly instantaneous risks associated with social media activism. The combination and interaction of these factors is incentivizing executives to reprioritize their behaviors away from their traditional fiduciary objectives of overtly pursuing the maximization of shareholder value (agency theory) to a pre-emptive strategy of avoiding catastrophic risks. Risk mitigation is leading to purposeful obfuscation of strategic activities, which is one reason scholarship has not kept up with the evolutionary changes in practice. Observations and implications at the firm level are then discussed.
Image Captioning of an Environment Using Machine Learning Algorithms (A Case Study of Gwarzo Road, Kano Nigeria)
Authors: Aliyu Muhammad , Bature Amir Abdullahi
Published: November 2024

This paper investigates the application of machine learning algorithms for automatic image captioning, focusing on a case study of Gwarzo Road in Kano, Nigeria. The research aims to design a robust VGG16/LSTM-based model that generates accurate and contextually relevant descriptions for images captured along the Kabuga to Bayero University Kano new site route. The methodology involves collecting images at three distinct times of the day (morning, afternoon, and evening) over 60 days, resizing and labelling them with relevant captions to build a comprehensive dataset. The VGG16 model, known for its efficiency in image processing, was employed for feature extraction, while the LSTM network was used to generate captions by interpreting the contextual and semantic details of the images. This study addresses key challenges in image captioning, such as localized object detection and generating meaningful textual descriptions, improving on existing datasets and models that often lack contextual relevance in specific environments. The expected outcomes of this research include the development of a precise caption generation model with high accuracy and efficiency. The resulting model achieved a BLEU score of 0.051, representing baseline performance in caption generation with partial alignment to human-generated references. Additionally, the model’s highest accuracy based on the loss function reached 55%, while the lowest accuracy was 50%, with an average accuracy of 53%. The creation of a localized image database further enhances the significance of this research for future applications and studies in image captioning.

The review of the Czech translation of the publication History of Theatre - Introduction (2022) characterizes and analyses the demand for a transformation of the theatrehistorical paradigm as proposed by Andreas Kotte. The author of the review perceives Kotte’s “introduction” as an expression of a trend shaping contemporary thinking about theatre, and therefore seeks to name the axiology, logic and limits of the argumentation Kotte works with, the inspirational power, but also the limitations of the theses he formulates. The purpose of the review is to expose, the inspiration but also the possible weaknesses of a more general transformation of views on the social role of theatre, theatre production and theatre operation.
TUNING THE THERMAL CONDUCTIVITY OF POROUS SILICON CARBIDE CERAMICS: A REVIEW
Authors:   International Educational Corporation, Kultayeva S. , Kurmanbekova E.B. ,   International Educational Corporation
Published: November 2024

Porous silicon carbide (SiC) ceramics possess unique thermal and structural properties, making them highly valuable for applications requiring high-temperature stability, corrosion resistance, and controlled thermal conductivity. Due to their superior characteristics, porous SiC ceramics are widely used in industrial and environmental applications, including thermal insulators, thermoelectric energy converters, fusion reactors, water purifiers, molten metal and hot gas filters, diesel particulate filters, heatable filters, heating elements, membrane supports, and catalyst supports. This paper reviews the key factors influencing the thermal conductivity of porous SiC ceramics, such as porosity, pore size, additive composition, and necking area. Understanding how each of these factors affects thermal conductivity can facilitate the design of SiC ceramics tailored to meet specific thermal and mechanical requirements. As the porosity of porous SiC ceramics increases, their thermal conductivity generally decreases. However, at a constant porosity, the thermal conductivity tends to increase with larger pore sizes. Additionally, the incorporation of conductive phases, thermally insulating secondary phases, or excess carbon or silicon significantly impacts the thermal conductivity. The development of the necking area between SiC grains also plays a critical role: a well-developed necking area improves heat transfer across the ceramic, thereby enhancing thermal conductivity. Based on these critical factors influencing thermal properties, a novel strategy for tuning the thermal conductivity of porous SiC ceramics is proposed.

Authors: Güncan Özge , Çelik Dilara
Published: November 2024

ÖZ
Sanatın tüm dalları arasında müzik; bir milletin kültür yapısının, ideolojik bakış açısının, toplumsal karakterinin ve değerlerinin şeffaf bir biçimde yorumlanmasını sağlamaktadır. Arthur Schopenhauer ve Friedrich Nietzsche’de müziğin diğer sanat formlarından daha derin, evrensel ve doğrudan etkili bir araç olduğunu öne sürmüş, insan duygularını etkileyen güçlü bir ifade biçimi olduğunu savunmuşlardır. Toplumsal ve bireysel yaşamda büyük etkiye sahip olan iletişim, kültürel mirasın nesilden nesile aktarılmasında, bununla birlikte örgün veya yaygın öğrenme faaliyetlerinde de önemli bir konumdadır. Bu anlamda sanat eğitiminin, öğrencilerin bilgiye ulaşma yolunda sağladığı çeşitlilik, karar verme ve sorun çözme becerilerinde alternatif bir süreç olduğu yadsınamaz gerçektir. Sosyal ve sivil hayatta görüşlerin paylaşılıp, tartışılabilecek birlikteliklerin sağlanması, eleştirel düşünmenin gelişimine katkı sağlamasına teşvik eden çalışmaları yürütmek üzere sanat eğitiminin örgün ve yaygın öğrenme faaliyetlerine yönelik fırsatlar sağladığı gözlemlenmektedir. Eğitim konusunda çok gelişmiş olan Lübnan, matematik ve fen eğitimi alanlarında dünyanın dördüncü ülkesi konumunda yer almaktadır. Lübnan’ın jeopolitik konumu ve kozmopolit etnik yapısı ülkenin tarihine olduğu kadar kültürel yapısına da büyük etki sağlamıştır. 500 yıl boyunca Osmanlı egemenliğinde olan Lübnan’da, Osmanlı kültürünün etkisi günümüzde hala etkisini sürdürmektedir. Çalışmada örnek alınacak Lübnan modeli, ülkelerarası kültür birliğini sağlaması anlamında seçilmiş olup, örgün ve yaygın öğretim faaliyetlerinde sanat eğitimi ile bilgi-beceri ve yaratıcılık gibi yeterliliklere imkân vermesi, aynı zamanda bu yetkinliğin güçlenmesi, farklı kültür ve ülkeler hakkında farkındalığın arttırılması ve uluslararası ağların oluşturulması gibi amaçlar gözetilmektedir.
A review of primary school teachers' insight into traditional instruction and activity-based learning in mathematics education
Authors: Oluwafemi Motunrayo Dairo  , Chioma Angela Okonkwo  , Christiana Uchechukwu Orakwe
Published: November 2024

This review paper explores primary school teachers' perceptions of two distinct instructional approaches in mathematics education: traditional instruction and activity-based learning (ABL). While traditional instruction is valued for its structured and efficient approach to foundational skill-building, it can sometimes result in student disengagement due to its emphasis on memorization and repetitive tasks. In contrast, teachers perceive ABL as fostering deeper understanding, engagement, and critical thinking by providing hands-on, interactive learning experiences. However, ABL requires more planning, classroom management, and alternative assessment methods, presenting unique challenges for teachers. This review highlights teachers' insights into the strengths and limitations of each approach and emphasizes the need for a blended instructional model that balances traditional structure with the exploratory benefits of ABL. Recommendations are provided for improving instructional practices through professional development, enhanced classroom resources, and assessment strategies that reflect both procedural fluency and conceptual understanding. The findings underscore the importance of equipping teachers with the tools to implement a hybrid teaching model that meets diverse student needs, thereby promoting a more engaging and effective mathematics education.

ViteArquiva nace de la voluntad de conocer y de contar la historia de un barrio desde el propio barrio. Vite (Santiago de Compostela) es un espacio urbano de viviendas sociales de finales de los años 70 del pasado siglo uno de los lugares más organizados a nivel asociativo de la ciudad siendo referente en la lucha vecinal. Este hecho marcará la identidad de un barrio que quiere ser contado y recordado. Partimos de un proceso colaborativo en el que diferentes agentes vecinales llevan a cabo una inmersión en su historia a través de la recopilación de su patrimonio material e inmaterial organizándolo de forma espontánea y autogestionada. ViteArquiva pretende ser un espacio donde la memoria de la vecindad pueda quedar depositada y salvaguardada creando una infraestructura social de conocimientos compartidos. Tiene el objetivo de realizar diferentes acciones entre varias generaciones, agentes y voces, como la creación de un archivo de la memoria del barrio, la “recogida” de historias de vida, o la organización de lo que denominamos “Cafés ConVite”, encuentros en los que compartir saberes sobre la historia de Vite. ViteArquiva no es simplemente un archivo de barrio, sino que es un archivo “vivo”. 
ViteArquiva was born from the desire to know and tell the story of a neighbourhood from the neighbourhood itself. Vite (Santiago de Compostela) is an urban area of social housing, built at the end of the 70s of the last century. It is one of the most organised places at an associative level, being a reference in the neighbourhood struggle of the city. This fact will mark the identity of a neighbourhood that wants to be told and remembered. We start from a collaborative process in which different neighbourhood agents carry out an immersion in their history through the compilation of their material and immaterial heritage, organising it in a spontaneous and self-managed way. ViteArquiva aims to be a space where the memory of the neighbourhood can be deposited and safeguarded, creating a social infrastructure of shared knowledge. Its objective is to carry out different actions between several generations, agents and voices, such as the creation of an archive of the neighbourhood’s memory, the “collection” of life stories, or the organisation of what we call “Cafés ConVite”, meetings in which to share knowledge about the history of Vite. ViteArquiva is not simply a neighbourhood archive, but a “living” archive.

A PROBLEMÁTICA DA COINFECÇÃO DO HIV E A TUBERCULOSE: UMA REVISÃO DE LITERATURA
Authors: Silva Brendo Rodrigues de Oliveira , Lima Ramon Fraga de Souza
Published: November 2024

Atualmente a tuberculose mata cerca de 250 mil crianças no mundo, sendo a maioria menor de 5 anos de idade. Além disso, o HIV é uma preocupação real e prevalente em países de terceiro mundo, e devido a isso, o alerta para a coinfecção das duas doenças deve ser um medo real e vigiado. Esta revisão teve como objetivo analisar ensaios clínicos controlados e ensaios clínicos controlados randomizados, totalizando 25 artigos sobre o tema, que foram selecionados após critérios de inclusão e exclusão. Através da análise dos estudos foi notório que a profilaxia empírica para TB não é indicada, e que a síndrome IRIS deve ser questionada sempre que se iniciar o TARV. Já a triagem, o acompanhamento longitudinal e a dose dupla da terapia antirretroviral, especificamente dolutegravir e raltegravir que foram estudos, em concomitância com a rifampcina é essencial para mudar o desfecho destes pacientes.

Abstract. Fine-scale mapping of pollutants based on mobile observations facilitates deep understanding of air pollutants distribution within a city and fosters science-based decisions to improve air quality, by adding up to the existing but not optimally distributed permanent monitoring stations. In this study, we developed high-resolution concentration maps of nitrogen dioxide (NO2), particulate matter (PM10) and ultrafine particles (UFP) for Bucharest, Romania, to evaluate the spatial variation of pollutants across the city during the warm and the cold seasons. Maps were generated using a mixed-effect method applied to a Land-use Regression (LUR) model. The approach relies on multiple land-use and traffic predictor variables, and assimilation of data collected by mobile measurements over 30 days in the periods May–July 2022 and January–February 2023. Cross-validation was done against in-situ data extracted from the same collection, while validation was organized by comparison with standard measurements at fixed reference sites. Our study shows that this combined method has a good performance for all pollutants (R2 > 0.65), the highest performance being observed for the cold season. PM10 concentration maps indicate multiple sources of particles during the warm season, the most important source being traffic. During the cold season PM10 concentration maps show a more uniform distribution of sources in Bucharest. The city’s principal roads, particularly the Bucharest ring road, are also highlighted in the NO2 maps, with higher gradient during the warm period.

Abstract. This study investigates the relationship between lidar-measured intensive optical properties of Saharan dust and simulated hematite content, using data collected during the Joint Aeolus Tropical Atlantic Campaign (JATAC) in 2021 and 2022. Measurements were taken in Mindelo, São Vicente, Cabo Verde. The study aims to determine how variations in hematite content influence the intensive optical properties of dust particles, particularly in the ultraviolet-visible (UV-VIS) spectrum. Given the well-documented impact of hematite on the extinction properties of dust, especially absorption in the UV-VIS range, our hypothesis is that these effects will be detectable in lidar measurements. Specifically, this study focuses on the lidar ratio, particle depolarization ratio and backscatter- and extinction-related Ångström exponents at 355 nm and 532 nm wavelengths. By analyzing dust plume cases separately regarding their size differences, the strongest positive correlation was identified between the backscatter-related Ångström exponent and hematite fraction (r=0.87, p=0.02). These findings contribute to improving the representation of dust in atmospheric models and refining calculations of its direct radiative effect, which often overlook the variability in mineralogical composition in their dust descriptions.
