Evaluation of Physical and Mechanical Properties of Coating Mortar with Partial Replacement of Sand by Blast Furnace Flue Dust
Authors: Carvalho Manoela da Silva , Arruda Vinicius Lima de , Simoni Leonardo , Oliveira Felipe Fernandes de , Fleming Robson
Published: February 2025

Abstract This study evaluates the potential partial replacement of sand by blast furnace flue dust (BFFD) in coating mortars to reduce the environmental impact caused by solid residues generated by the iron-making industry. Mortars were produced with varying rates of sand replacement by BFFD, and curing was conducted at room temperature and in lime-saturated water. Axial and radial compressive strength were evaluated at ages up to 28 days, and density, water absorption, and apparent porosity were measured after 28 days of curing. The results indicate that partial replacement of sand by BFFD is viable after curing at ambient conditions, leading to a reduction in mortar density without significantly altering compressive strength. However, the compressive strength of BFFD-added mortars decreases when curing is carried out in water-saturated lime.

Authors: Pimentel Susana Couto , Miranda Theresinha Guimarães
Published: February 2025

Resumo A crise sanitária decorrente da pandemia de Covid-19 gerou medidas de distanciamento social para minimizar os riscos de contágio pelo coronavírus, impelindo as instituições de educação básica e superior a ofertarem o Ensino Remoto Emergencial (ERE). Dentre os desafios do ERE, as instituições precisaram construir alternativas para: formação dos docentes, disponibilização de ferramentas digitais, ampliação das redes de dados e garantia de acessibilidade para estudantes com deficiência. Nesse sentido, esta investigação teve como objetivo analisar as orientações das universidades que compõem o sistema estadual de educação da Bahia quanto à abordagem de questões relativas à acessibilidade de estudantes com deficiência ao ensino remoto em cursos de graduação. As orientações foram buscadas nos sítios eletrônicos de cada instituição. Trata-se, portanto, de uma pesquisa documental, de abordagem qualitativa, que permitiu uma perspectiva analítica-interpretacionista sobre o teor das orientações institucionais. Os resultados revelam que as quatro universidades estaduais da Bahia abordam a acessibilidade nos documentos relativos ao ensino remoto, sendo a maior ênfase na dimensão digital e metodológica. Apenas a Universidade Estadual do Sudoeste da Bahia disponibilizou um documento com orientações específicas que contemplam também as dimensões: comunicacional, instrumental, atitudinal e digital. Conclui-se que as instituições de Educação Superior precisam construir políticas que assegurem o direito de acessibilidade dos estudantes com deficiência ao ensino, presencial ou remoto, bem como aos espaços, conteúdos e instrumentos de aprendizagem.

Published: February 2025

Abstract The concept of prestressing in concrete beams and its associated calculation procedures are well-established in the literature. However, its application in composite steel-concrete beams has been increasing despite lacking a specific approach in the main design codes. In many cases, designers are required to combine available criteria for calculating steel and reinforced concrete structures. This study aimed to formulate an optimization problem and assess CO2 emissions for the optimal design of composite steel-concrete beams with external prestressing. The design variables considered in the optimization problem include the cross-section of laminated or welded profiles, slab height, characteristic compressive strength of concrete, and the number of tendons. Solutions to the optimization problem were obtained by implementing a Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The analyses included comparisons with experimental examples and optimization problems involving prestressed steel beams. Additionally, a parametric analysis across various spans was performed, allowing the identification of factors with the greatest impact on CO2 emissions. The results indicate that the chosen algorithms effectively generated solutions for the problem, with PSO generally outperforming GA. In terms of emission composition, steel was identified as the largest contributor. Furthermore, welded profiles showed better performance, allowing the omission of prestressing for spans up to 27.5 m, whereas, for laminated profiles, prestressing becomes necessary from 17.5 m. Optimal solutions were found for concrete with a compressive strength greater than 25 MPa.

Occupational therapists views and perceptions of Functional Capacity Evaluation of employees suffering from major depressive disorders.
Authors: Ramano Enos Morankoana , Buys Tania
Published: February 2025

Introduction: Major depressive disorders (MDD) cause work disability and work loss, often resulting in unemployment. Employees with MDD are often referred to occupational therapists (OTs) to assist with functional capacity evaluation (FCE). FCE forms a part of the return-to-work decision making process. This study describes the views and perceptions of occupational therapists regarding the requirements needed to conduct reliable FCEs of employees suffering from MDD. This research formed part of a larger study for a masters' degree assessing the methods used by South African occupational therapists to formulating return to work decision.Methods: This study employed an interpretative phenomenology. Data was collected in three phases using a descriptive open-ended questionnaire, focus groups and member checking groups. Thematic content data analysis was used.Findings: In total, 78 occupational therapists were recruited and 39 participated, with response rates of (28) 47%, (11) 61% and (9) 82% respectively across the three phases. Three themes emerged, namely: (1) occupational therapists' competencies in performing functional capacity evaluation (2) the process of functional capacity evaluation and (3) comprehensive functional capacity evaluation.Conclusion: The purpose of functional capacity evaluation is to formulate return-to-work decisions. Occupational therapists should be competent in the use of standardised measurement tools, non-standardised assessment and clinical reasoning rather than use intuitive guesswork.Key words: Major Depressive Disorder, Functional Capacity Evaluation, occupational therapy.
Occupational therapy in the bereavement process: A meta-synthesis
Authors: Dahdah Daniel Ferreira , Joaquim Regina Helena Vitale Torkomian
Published: February 2025

Introduction: Bereavement is a complex process characterised by a state of grief and suffering, which impacts the health and well-being of the bereaved, and extends to their occupational performance. Thus, occupation can be understood to be central in the expression of bereavement after the death of a loved one as it mediates identity formation, interpersonal relationships, a sense of belonging, and future perspectives. Purpose: To review English and Portuguese literature and identify how occupational therapists perceive and/or intervene in the bereavement process.
Method: A meta-synthesis was conducted by database search and article analysis. Results and Discussion: Eight qualitative style articles were analysed. From these, three categories were derived from the content analysis: 1) Relationship between study participants and the deceased; 2) Occupational repercussions of bereavement; and 3) Occupation as a means to an end in the therapy process of the bereaved.
Conclusions: Although the need for studies of the bereavement process and its implications for occupations is urgent, this study points out that occupations can be predictors of understanding the elaboration process through occupational engagement and that they also act as a potential resource to construct meaning about the death of the loved one.

The paper is aimed to investigate the role of predictive profiling (hereafter PP) in the fight against cross-border crime and terrorism. The main tasks of the article are to describe the content of PP, the added value of its implementation and how it can be used in the State Border Guard Service of the Republic of Latvia (hereafter SBGS) as a complement to risk assessment in operational situations. The authors of the paper explores the content of the PP implemented in the Royal Netherlands Marechaussee (hereafter KMar), as well as in Slovakia, Spain and several Central Asia region countries. For this purpose analysis and evaluation of documents, scientific, pedagogical and psychological literature was performed and suggestions for the improvement of border guard service threat detection system in the field of PP were compiled.The paper outlines the goal of PP, which is to identify, assess, and take action on a potential criminal or terrorist threat as early as possible (preferably during preparatory actions). Deviant behaviour in combination with Attacker Method of Operation forms a key concept. The AMO provides the indicators for the deviant behaviour. Furthermore, the paper delves into the system of PP and its corresponding process steps. PP is focused on the threat, not the risk, making it a threat analysis.
THE IMPORTANCE AND NECESSITY OF LAND-BASED MILITARY EQUIPMENT IN THE STATE BORDER GUARD
Authors: Korklis Andrejs , Rižovs Rihards
Published: February 2025

The ability of State Border Guard (henceforth - SBG) personnel to respond swiftly, utilizing all available SBG resources to counter any threats at the national border, is a critical aspect of ensuring state security. In modern times, the SBG collaborates closely with the National Armed Forces (henceforth - NAF), engaging SBG personnel in joint training and providing them with necessary equipment. This cooperation is essential as, during a state of emergency or wartime, the SBG integrates into the NAF. To foster stronger collaboration between the personnel of these two state institutions, SBG officers undergo extensive familiarization with NAF combat tactics, communication systems, firearms, and military equipment, with particular emphasis on land-based military vehicles. The use of military equipment in border security operations would enhance border guards' familiarity with the fundamental principles of operating and managing such technology, which would be beneficial in broader national defense efforts. One of the primary features of military equipment is its capability to be armed, coupled with increased off-road mobility and high durability. These characteristics are highly relevant to the SBG, as its personnel often need to traverse terrain where conventional roads are absent.The purpose of the study: Investigate and analyze the types of military equipment and the possibilities of their use in the provision of border surveillance.Main tasks:1. Study the land military equipment at the disposal of NAF;2. To analyze which of the NAF military equipment can be used in ensuring the security of the state border;3. To express proposals on what kind of military equipment could be used in observing the regimes of the state border.Research methods:1. Empirical research method (interview);2. Qualitative research method (situation analysis);3. Method of logical analysis.
Co-produced translation and transformation of knowledge and policy: context-adaptive mobility of compact city ideals / Interpretación (co-producida) y transformación de conocimientos y políticas: una transferencia de los ideales relativos a las ciudades compactas adaptada al contexto

Published: February 2025

The compact city is an ideal model for sustainability, transferred between cities as ‘best practices’. This article investigates how context-adaptive transfer of compact city ideals can take place, using Barcelona, Rotterdam and Gothenburg as examples. The objectives are to 1) summarize urban qualities discussed by stakeholders in the three cities; 2) uncover dominant urban challenges and strategies among Barcelona, Rotterdam and Gothenburg stakeholders; and 3) present how Barcelona/Rotterdam ‘best practices’ are translated and transformed by Gothenburg stakeholders into situated ‘good practices’. The data were collected through semi-structured interviews with 82 stakeholders in Barcelona and Rotterdam and a workshop with 17 stakeholders in Gothenburg. The article shows that any meaningful and consequential mobility of knowledge through best practices requires stakeholder-enabled translation involving social learning and co-production of locally relevant knowledge. This means that a wide range of stakeholders needs to be engaged, including affected citizens, to secure representation and transparency. To succeed, best practices need embellishment with sufficient contextual information in formats possible to understand and process by these stakeholders. Strengthened involvement of stakeholders in transfer, translation and transformation of ‘best practices’ into ‘good practices’ requires improved models for stakeholder engagement, moving away from prevalent top-down attitudes of many city governments.
Circuitos espaciales de producción generados por la pesca y el transporte de productos pesqueros en Quintana Roo, México / Spatial networks created by fishing and fishery products transportation in Quintana Roo, Mexico
Authors: Casado Izquierdo José María , Crespo Guerrero José Manuel
Published: February 2025

Partiendo del enfoque teórico de Milton Santos y del uso de metodologías cuantitativas y cualitativas, se analizan los circuitos espaciales de producción generados por la pesca y el consumo de productos pesqueros en Quintana Roo. Como antecedentes se aborda la apropiación y explotación inicial de la costa quintanarroense por la pesca y otras actividades, una apropiación hoy cuasi monopolizada por el turismo. La pesca actual se centra en la langosta viva capturada por unas pocas cooperativas, principalmente en el centro y sur del estado, aunque en el pasado la tortuga marina fue la principal especie comercial. Los circuitos espaciales revelados reflejan una densa red de relaciones espaciales, una red donde Cancún-Puerto Juárez funge como nodo central a escala estatal. Estos circuitos presentan una estructura multiescalar, aunque en ocasiones se organizan en torno a productos, escalas y espacios específicos. Es el caso del camarón, cuya alta demanda domina la escala nacional y explica su aprovisionamiento desde Sinaloa y Sonora, y también desde Belice. Los circuitos de la langosta reflejan una situación paradójica: mientras la langosta viva capturada en el estado se destina al mercado asiático, el consumo local se nutre de cola de langosta del vecino Yucatán; además, en estos circuitos internacionales Cancún funge principalmente como simple punto de acopio e intermediación, subordinado a Ensenada. La investigación revela como recursos pesqueros locales de distinta procedencia son destinados a satisfacer una creciente demanda turística e internacional, lo que otorga tintes extractivistas a estos circuitos y compromete la sostenibilidad de los mencionados recursos.

Published: February 2025

Report
Introduction: The implantation of an antimicrobial spacer (AMC) is widely used in the complex treatment of PPI. Most often, bone cement is additionally impregnated with vancomycin, which is active only against Gram-positive bacteria. However, there is an increase in the resistance of gram-negative bacteria to most antibiotics worldwide, which requires the development of new approaches to overcome this resistance, including the use of local antibacterial therapy.
Objective: to study the duration of antimicrobial activity and strength properties of samples of gentamicin-containing bone cement additionally impregnated with various combinations of highly dispersed silver (HD-Ag) with various antibiotics.
Materials and methods: In the experimental work, samples of DePuy CMW 3 PMMA bone cement with a content of 4.22% gentamicin (control) were used. Additionally, 6 samples were produced and tested with the addition of different combinations of antibacterial drugs. Antimicrobial activity (AMA) was evaluated against S. aureus (MSSA, MRSA), K. pneumoniae, and P. aeruginosa. The strength properties of the most effective samples were evaluated in accordance with GOST ISO 5833-2011 in comparison with the control. Statistical analysis was performed using the Past 4 software system.
Results: Control samples from the official bone cement showed the shortest duration of activity against MSSA (7 days) and showed no activity against MRSA and gram-negative bacteria. Adding 10 wt.% of fosfomycin and B-Ag in bone cement (HC 1) increased the duration of AMA in relation to MS, K. pneumoniae and P. aeruginosa by three times. Addendum to KS1 5 wt.% of vancomycin (CC2) extended the AMA of samples against gram-negative bacteria to 14-16 days, and staphylococcus to 4 weeks. Samples with B-Ag and 10 wt had the highest activity against gram-negative bacteria.% of aztreonam (CC 5 and CC 6), the strength characteristics of which did not significantly differ from the control samples.
Conclusion: Combinations containing HD-Ad, vancomycin, fosfomycin, and aztreonam have shown long-term AMA, which may improve the results of the sanitizing stage of the two-stage treatment of PPI TBS, making them promising for clinical use.
Keywords: peri-implant infection, antimicrobial spacer, highly dispersed silver, bone cement impregnation.

Spiritual development, centered on concepts such as taqwa (awareness of Allah) and tafaqquh fi al-din (deep religious understanding), is analyzed alongside psychological growth, encompassing cognitive, emotional, and behavioral aspects. Utilizing a mixed-methods approach, the study conducted quantitative analysis through Structural Equation Modeling (SEM) and qualitative analysis of reflective journals. The findings reveal that spiritual development is significantly correlated with psychological well-being (r = 0.64, p < 0.01), religiosity (r = 0.71, p < 0.01), and academic performance (r = 0.42, p < 0.01). Psychological well-being mediates the relationship between spiritual development and academic performance. The SEM model shows strong fit indices, with CFI and TLI values ​​above 0.90 and RMSEA below 0.06. The novelty of this research lies in integrating Islamic spiritual concepts such as tazkiyah al-nafs (soul purification) with modern psychological theories, providing a comprehensive framework for the spiritual-psychological development of Muslim students. Recommendations include incorporating these findings into Islamic education by developing holistic curricula, improving Islamic guidance and counseling, and enhancing educator competencies. Future studies should explore larger samples and longitudinal designs to investigate these relationships further.

This study investigates the factors influencing young Muslims' decisions to leave Islam, utilizing a qualitative approach and digital ethnography methods. TikTok, as a prominent platform for youth expression, serves as the research focus. Data were gathered through non-participatory observation of relevant content and analyzed using thematic analysis. Three primary themes emerged: Faith Struggles, Environmental Influences, and Interpersonal Relationships. Faith struggles arise from internal conflicts between religious values and personal life experiences, including mismatches between faith and identity. Environmental influences stem from exposure to diverse cultures and religions, fostering emotional attachments. Interpersonal relationships, particularly interfaith marriages, significantly contribute to conversion decisions. The findings underscore TikTok's role as a platform for identity exploration among youth, offering valuable insights for religious communities to address spiritual needs amidst modernity and identity crises.
