Abstract Textile reinforced concrete emerges as an alternative for the strengthening of reinforced concrete structures. However, as a relatively new material, there is still no regulatory body or standardization that standardizes the manufacturing and application processes of the material, which generates significant differences regarding its characteristics and properties. From this perspective, this study seeks to experimentally evaluate the mechanical performance of textile reinforced concrete when applied as reinforcement of reinforced concrete beams subjected to four-point bending tests, using the alkali-resistant fiberglass textile produced in Brazil, TEXIGLASS AR-360-RA-04. As an exploratory study, the experimental program consists of fourteen reinforced beams and one rectangular cross-section reference beam (120 mm wide, 200 mm high, and 1500 mm long), totaling fifteen beams. As variables, the bond strength at the textile-matrix interface is investigated based on (a) the type of matrix (industrialized polymer mortar or self-compacting mortar) and (b) the surface treatment of the textile in four configurations: uncoated textile (UT), coated with epoxy (E), fully coated with epoxy and sand (ES) or fully coated with epoxy and partial sand (EPS). From the results, it was mainly found that: all reinforced beams showed increases in (a) load-carrying capacity, (b) ductility and (c) toughness. Despite the great variability of results, the coating technique in the EPS textile specimens proved promising. structures However material properties perspective fourpoint point tests alkaliresistant alkali resistant Brazil AR360RA04.

Resumo O concreto têxtil surge como uma alternativa para o reforço de estruturas de concreto armado. Porém, por ser um material relativamente novo, inexiste ainda um órgão ou norma regulamentadora que uniformize os processos de fabricação e de aplicação do material, o que gera diferenças significativas quanto às suas características e propriedades. Sob esta perspectiva, este estudo busca avaliar experimentalmente o desempenho mecânico do concreto têxtil ao ser aplicado como reforço de vigas em concreto armado submetidas ao ensaio de flexão a quatro pontos, utilizando o têxtil de fibra de vidro álcali-resistente de produção brasileira TEXIGLASS AR-360-RA-04. De caráter exploratório, o programa experimental é composto por quatorze vigas reforçadas e uma viga testemunho de seção retangular (120 mm de largura, 200 mm de altura e 1500 mm de comprimento), totalizando quinze vigas. Como variáveis, investigam-se a resistência de ligação na interface têxtil-matriz a partir do (a) tipo de matriz (argamassa polimérica industrializada ou argamassa autoadensável) e do (b) tratamento superficial do têxtil em quatro configurações: têxtil sem revestimento (SR), revestido com epóxi (E), totalmente revestido com epóxi e areia (EA) ou totalmente revestido com epóxi, mas com areia somente nas extremidades (EAP). A partir dos resultados, verificou-se principalmente que: todas as vigas reforçadas apresentaram aumentos da (a) capacidade resistente, (b) ductilidade e (c) tenacidade.

ABSTRACT The objective of this research was to assess the performance of pavement-quality concrete having 100% copper slag as fine aggregate in the presence of steel fibre. In this research, the crimped steel fibre of two lengths (30 mm and 50 mm) and different dosages such as 0.5%, 1.0%, 1.5%, and 2.0% by weight of concrete are included in the concrete having 100% copper slag as fine aggregate and compared with the concrete having river sand and copper slag as fine aggregate without fibre. The mechanical characteristics that are being examined include fatigue performance, bond strength, impact strength, flexural strength, stress-strain behaviour, abrasion resistance, and slabs exposed to both static and cyclic loading. According to the experimental findings, pavement concrete that contains 100% copper slag as fine aggregate and 1% crimped steel fibre in both 30 and 50 mm diameters performs better and is more optimal. An inventive way to manage copper slag waste and create durable, stiff pavement construction is with copper slag in concrete road construction. Utilising copper slag in concrete road construction offers a novel approach to waste management and the creation of environmentally friendly concrete road construction. pavementquality quality 100 (3 5 05 0 0.5% 10 1 1.0% 15 1.5% 20 2 2.0 strength stressstrain stress strain behaviour resistance loading findings 3 optimal durable ( 0.5 1.0 1.5 2. 0. 1.

ABSTRACT The construction sector plays a fundamental role in social development, but is responsible for the consumption of the world’s natural and energy resources. Therefore, research seeks to incorporate waste into the production of materials, aligning with global goals for reducing CO2 emissions, disposal in landfills and resource extraction. Among industrial waste, waste from the glass cutting process (GCW) stands out, little explored in the literature and with significant rates of disposal in landfills. Therefore, this research aims to evaluate the properties of mortars incorporating GCW, as a partial replacement for Portland cement and aggregate, through a comprehensive investigation of the properties of the material produced. The materials that make up the mixtures and mortars were characterized in accordance with regulatory requirements. The data obtained were analyzed using the analysis of variance (ANOVA) methodology and Tukey test. The results showed that the GCW influenced the consistency index, the specific gravity and the tensile bond strength of the mortars, reducing water absorption, capillary absorption and shrinkage. As for compressive strength, it was observed that up to 10% by GCW, replacing cement, does not compromise this property, with a relative increase in strength when replacing sand. As for durability, there was an improvement in this property. It is concluded that the use of GCW, in partial replacement of Portland cement and fine aggregate, in the production of mortars is a technical alternative, as it presented performance that enables its use, and meets the principles of sustainable development, which present capable alternatives to contribute to saving energy and natural resources. development worlds world s resources Therefore CO emissions extraction (GCW out aggregate produced requirements ANOVA (ANOVA test index shrinkage 10 property sand durability alternative 1

RESUMO O setor da construção civil desempenha um papel fundamental no desenvolvimento social, mas é responsável pelo consumo de recursos naturais e energéticos do mundo. Portanto, as pesquisas buscam incorporar resíduos na produção de materiais, alinhando-se com metas globais de redução das emissões de CO2, descarte em aterros sanitários e extração dos recursos. Entre os resíduos industrias, destaca-se o resíduo proveniente do processo de lapidação do vidro (RLV), pouco explorado na literatura e com taxas significativas de descarte em aterros. Assim, esta pesquisa tem como objetivo avaliar as propriedades de argamassas com incorporação de RLV, em substituição parcial ao cimento Portland e ao agregado, por meio de uma investigação abrangente das propriedades do material produzido. Os materiais componentes das misturas e as argamassas foram caracterizados de acordo com as prescrições normativas. Os dados obtidos foram analisados por meio da metodologia de análise de variância (ANOVA) e teste de Tukey. Os resultados mostraram que o RLV influenciou no índice de consistência, na massa específica real e na aderência à tração das argamassas, reduziu a absorção de água, absorção por capilaridade e retração. Quanto à resistência à compressão, observou-se que até 10% pelo RLV, em substituição ao cimento, não compromete esta propriedade, havendo aumento relativo de resistência, quando em substituição à areia. Já para a durabilidade, houve uma melhoria nesta propriedade. Conclui-se que a utilização de RLV, em substituição parcial ao cimento Portland e ao agregado miúdo, na produção de argamassas é uma alternativa técnica, pois apresentou desempenho que possibilita seu uso, e atende aos princípios do desenvolvimento sustentável, os quais apresentam alternativas capazes de contribuir para a economia de energia e recursos naturais. social mundo Portanto alinhandose alinhando se CO2 CO industrias destacase destaca , (RLV) Assim produzido normativas ANOVA (ANOVA Tukey consistência água retração compressão observouse observou 10 propriedade areia durabilidade Concluise Conclui miúdo técnica uso sustentável (RLV 1

RESUMEN El objetivo de este estudio fue analizar los efectos del aislamiento social resultante de la pandemia de COVID-19 en la vida familiar, con énfasis en la experiencia de la maternidad y la relación con los niños. Participaron 20 madres de estratos sociales medios, de 29 a 45 años de edad, que mantenían actividades laborales a distancia y se encontraban en aislamiento social. Se realizaron entrevistas individuales exhaustivas por medios digitales. El material recopilado se transcribió y se sometió a un análisis de contenido temático. Los resultados mostraron que los cambios impuestos por la pandemia afectaban directamente a la vida familiar, lo que explicaba las desigualdades de género en la organización rutinaria, la distribución de las tareas domésticas y el cuidado de los niños. Se observó una relación ambivalente entre las madres y la maternidad y sus imperativos sociales, que reverberaban en el vínculo que establecen con sus hijos. El análisis revela que la sobrecarga emocional y física contribuye a exacerbar los sentimientos de culpa y soledad experimentados en la relación con la maternidad, además de mostrar conflictos en el desempeño de los papeles de madre, esposa y profesional. Las mujeres entrevistadas mostraron agotamiento con las demandas domésticas y el cuidado de sus hijos, además de conflictos relacionados con el desajuste entre las expectativas y las normas sociales que regulan el ejercicio de la maternidad y sus experiencias personales como madres. Las conclusiones sugieren la presencia de una crisis de identidad ligada a los ideales sociales vinculados a las experiencias de la maternidad, lo que invita a pensar en la urgencia de mirar el sufrimiento materno, tratando de comprender las dimensiones subjetivas de las transformaciones en tiempos de aislamiento social.

ABSTRACT This study aimed to analyze the impacts of the social isolation resulting from the COVID-19 pandemic on family life, with emphasis on the experience of motherhood and the relationship with children. Twenty mothers from the middle social strata, from 29 to 45 years old, who kept working activities at a distance and were in social isolation, participated. In-depth individual interviews were conducted by digital means. The collected material was transcribed and submitted to thematic content analysis. The results showed that the changes imposed by the pandemic directly impacted family life, highlighting gender inequalities in routine organization, distribution of household tasks and parental care. An ambivalent relationship was observed between mothers and maternity and their social imperatives, which reverberated in the bond they establish with their children. The analysis reveals that emotional and physical burden contributes to exacerbate feelings of guilt and loneliness experienced in the relationship with motherhood, in addition to showing conflicts in the performance of the roles of mother, wife and professional. The women interviewed showed exhaustion with domestic and child care demands, in addition to conflicts related to the mismatch between expectations and social standards that regulate the exercise of motherhood and their personal experiences as mothers. The conclusions suggest the presence of an identity crisis due to the social ideals linked to the experiences of motherhood, which invites us to think about the urgency of looking at maternal suffering, seeking to understand the subjective dimensions of the transformations that this experience goes through in the times of social isolation.

This study explores the use of commonly utilized materials (sulphoaluminate cement, fly ash, expanding agent) in the creation of three inorganic coatings (C-coating, F-coating, E-coating) to improve the interlayer bonding properties of 3D printed mortar. The mechanical properties of mortar with/without coating were characterized by compressive test and flexural test. The bonding properties of the coatings were assessed through splitting tests and micron indentation tests. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to analyze the characteristics of hydration products and pore structure. The findings demonstrate that both F-coating and E-coating significantly enhance the mechanical properties of 3D printed mortar. Specifically, F-coating led to a 42% increase in flexural strength and a 71% increase in bond strength. The XRD and SEM analyses revealed that the fly ash contained in F-coating has a pozzolanic effect by reducing the content of Ca(OH)2 (CH), promoting the formation of calcium silicate hydrate (C-S-H) gel, and enhancing microscopic morphology. The expansion agent contained in the E-coating could significantly increase the content of AFt, and the needle-like AFt plays a good bonding performance between the interfaces. In this manuscript, two kinds of cheap and easy-to-obtain interlayer coatings for 3D printing mortar are found. sulphoaluminate cement Ccoating, Ccoating C coating, (C-coating Fcoating, Fcoating F Ecoating E D withwithout with without Xray X ray (XRD (SEM structure Specifically 42 71 CaOH2 CaOH Ca OH 2 Ca(OH) CH, CH , (CH) CSH S H (C-S-H gel morphology needlelike needle like interfaces manuscript easytoobtain easy obtain found 4 7 Ca(OH (CH

Steel and cement production emits CO2, spurring research for alternatives. Concrete materials are studied for shortages and enhancement. Construction, especially steel structures, will grow, but costs and shortages loom. Developing countries face steel scarcity and higher costs. Researchers explore natural or synthetic fiber replacements for steel, with bamboo showing promise. This study examines bamboo, with and without epoxy coating, as a steel substitute. Bamboo can replace steel in small or non-critical structures. The article explores bamboo's properties and behavior in reinforced concrete. Treating bamboo is vital for bond strength and flexural behavior under static loads. Three coatings are tested: natural, epoxy-coated, and epoxy with sand-coated bamboo. Twelve slab specimens are tested per Indian standards against steel-reinforced concrete slabs. The study evaluates bond strength, flexural behavior, and crack resistance using ultrasonic pulse velocity tests. Epoxy and sand-coated bamboo show significant improvement in bond strength, flexural performance, and concrete quality.

ORIENTATION: The changing demands employees experience because of the turbulent and competitive world of work has increased their workload, necessitating a focus on their well-being to ensure their contribution to the effectiveness of organisations. RESEARCH PURPOSE: The purpose of this study was to investigate the relationship between employee well-being (EWB) and organisational effectiveness (OE) in a South African bond origination company. MOTIVATION FOR THE STUDY: Organisations need to improve their effectiveness to remain competitive and are dependent on the well-being of their employees to achieve this. Understanding the effect of EWB on OE can assist organisations in managing this relationship. RESEARCH DESIGN/APPROACH AND METHOD: A quantitative cross-sectional approach was used in which a convenient sample of 203 employees completed five questionnaires to measure OE and the four underlying contructs of EWB. A correlation analysis was conducted to determine the statistical relationship between the four EWB constructs and OE. MAIN FINDINGS: Results indicated a statistically significant positive relationship between job satisfaction, work engagement and OE and a statistically significant negative relationship between Burnout and OE, while no relationship was found between workaholism and OE. PRACTICAL/MANAGERIAL IMPLICATIONS: Managers should implement interventions to increase job satisfaction and work engagement and decrease burnout to increase the performance of their organisations. CONTRIBUTIONS/VALUE-ADD: This study provides managers with an understanding of how the performance of their organisations can be improved by managing the well-being of their employees.

ABSTRACT In this article, the result of research that focused on the ethical dimension of the pedagogue's work with gender and sexuality issues at school, the objective was to analyze the ethical formation, from the point of view of moral development, of undergraduate students in Pedagogy at a public University in São Paulo. The sample was composed of 165 subjects enrolled in the initial and final years of the course that set the research. To measure their ethical background, Kohlbergian and neo-Kohlbergian approaches to moral development and the Defining Issues Test 2 (DIT-2) were used. The results showed that the ethical formation of undergraduate students remains stagnant and even indicates a certain regression throughout the course. In addition, the low performance of the participants was strongly related to their religious bond, implying that the bond and the religious formation can delegitimize and curb their ethical formation. article pedagogues pedagogue s school Paulo 16 background neoKohlbergian neo DIT2 DIT (DIT-2 used addition 1 (DIT- (DIT

The catalytic performance of γ-Fe2O3 nanopowder was investigated in the acetone hydrodeoxygenation (HDO) reaction, an essential catalytic reaction in biomass valorization. Sequential reduction/oxidation thermal pre-treatments of the γ-Fe2O3 nanopowder induced significant structural and electronic modifications that directly impacted its catalytic performance. The co-existence of Fe3+/Fe2+/Fe0 sites led to different reaction pathways (C-C coupling, hydrogenolysis, hydrogenation, and (hydro)deoxygenation) that formed a wide range of products. The correlation of the catalytic and structural data provided a better understanding of C-O, C-C, and C-H bond activation under the HDO reactional stream in the presence of metallic and oxidized phases of iron. This study demonstrates the tunability of FeOx catalysts in the acetone HDO reaction to favor different reaction pathways and the formation of products. It highlights that tailoring active sites is crucial for developing selective and optimized catalysts for the HDO reaction. γFe2O3 γFeO γ Fe2O3 Fe O γ-Fe2O (HDO valorization reductionoxidation reduction oxidation pretreatments pre treatments coexistence co existence Fe3Fe2Fe0 FeFeFe Fe3 Fe2 Fe0 Fe3+/Fe2+/Fe CC C coupling hydrogenolysis hydrogenation hydro deoxygenation (hydro)deoxygenation products CO, CO O, C-O CC, C, C-C CH H iron γFe γFe2O FeO Fe2O Fe3Fe2Fe

A Atenção Primária à Saúde (APS) atende às necessidades individuais e coletivas da sua população adstrita. Dessa forma, considera-se que a equipe de saúde acolhe as mulheres, que sofreram violência. Contudo, os estudos mostram a fragilidade nos atendimentos a esse grupo. Nesse sentido, questiona-se, especificamente, a atuação dos enfermeiros. Eles são capazes de reconhecer, de maneira precoce, as usuárias do serviço de saúde, que sofrem, ou que correm risco de sofrer violência? Denunciariam a violência contra mulheres atendidas, na unidade de saúde? Existe um ditado, muito forte no Brasil, que diz: “em briga de marido e mulher, não se mete a colher”. Será que esta crença interfere nas ações dos enfermeiros da Atenção Primária à Saúde (APS)? Diante deste contexto, a pergunta desta investigação é: “Como o enfermeiro atua perante a violência contra a mulher na APS?” Objetivo: Identificar e sistematizar a atuação do enfermeiro perante a violência contra a mulher na APS. Método: Utilizou-se da Revisão Integrativa, buscando nas bases de dados LILACS e BDENF, no período entre 2011 a 2021, e nos idiomas inglês e português, artigos que respondiam à pergunta de pesquisa. Resultados: Os encaminhamentos para serviços especializados, serviço social e de psicologia, construção do vínculo, acolhimento e empatia são atuações promovidas pelos enfermeiros na APS. Considerações Finais: Considera-se que a revisão integrativa alcançou os objetivos propostos, uma vez que foi possível identificar e sistematizar a atuação do enfermeiro. Este profissional possui o papel de coordenador e, por sua vez, integrador da equipe. É importante que o mesmo elabore atividades de capacitação, atue com uma visão holística e multiprofissional, devido à alta complexidade da violência doméstica contra a mulher.

Primary Health Care (PHC) meets the individual and collective needs of its assigned population. Thus, it is considered that the health team welcomes women who have suffered violence. However, studies show the fragility of care for this group. In this sense, the role of nurses is specifically questioned. Are they able to recognize, at an early stage, users of the health service who suffer, or who are at risk of suffering violence? Would they denounce violence against women assisted at the health unit? There is a saying, very strong in Brazil, that says: "in a fight between husband and wife, don't get involved". Does this belief interfere with the actions of Primary Health Care (PHC) nurses? Given this context, the question of this investigation is: “How do nurses act in the face of violence against women in PHC?” Objective: To identify and systematize the role of nurses in the face of violence against women in PHC. Method: The Integrative Review was used, searching the LILACS and BDENF databases, in the period between 2011 and 2021, and in English and Portuguese, for articles that answered the research question. Results: Referrals to specialized services, social and psychological services, bond building, welcoming and empathy are actions promoted by nurses in PHC. Final Considerations: It is considered that the integrative review achieved the proposed objectives, since it was possible to identify and systematize the nurse's performance. This professional has the role of coordinator and, in turn, integrator of the team. It is important that he develop training activities, act with a holistic and multidisciplinary vision, due to the high complexity of domestic violence against women.

Abstract This study aimed to evaluate the effect of antioxidant solutions on fracture strength and bonding performance in non-vital and bleached (38% hydrogen peroxide) teeth. One hundred and eighty dentin specimens were obtained, 60 for each test: fracture strength, hybrid layer thickness, and bond strength. The groups (n=10) were randomly composed according to post-bleaching protocol: REST - restoration, without bleaching; BL - bleaching + restoration; SA - bleaching, 10% sodium ascorbate solution, and restoration; AT - bleaching, 10% α-tocopherol solution, and restoration; CRAN - bleaching, 5% cranberry solution, and restoration; CAP - bleaching, 0.0025% capsaicin solution, and restoration. Data were analyzed with ANOVA, Kruskal-Wallis, Dunn, and Qui-Square tests (α=0.05). The highest fracture strength values were observed in REST (1508.96 ±148.15 N), without significant difference for the bleached groups (p>0.05), regardless of the antioxidant use. The hybrid layer thickness in the group that was not subjected to bleaching (REST) was significantly higher than in any other group. The bond strength in the bleached and antioxidants-treated groups (SA, AT, CRAN, CAP) has no differences with the bleached group without antioxidants (BL). Adhesive failures were predominant in the groups that did not receive the antioxidant application. In conclusion, the evaluated antioxidants did not show an effect on the fracture strength, hybrid layer thickness, or bond strength of dentin bleached after endodontic treatment. The application of 10% sodium ascorbate, 10% alpha-tocopherol, 5% cranberry, or 0.0025% capsaicin solutions is not an effective step and should not be considered for the restorative protocols after non-vital bleaching. nonvital non vital 38% 38 (38 peroxide teeth obtained 6 test n=10 n10 n 10 (n=10 postbleaching post protocol restoration solution αtocopherol α tocopherol 5 00025 0 0025 0.0025 ANOVA KruskalWallis, KruskalWallis Kruskal Wallis, Wallis Kruskal-Wallis Dunn QuiSquare Qui Square α=0.05. α005 α=0.05 . 05 (α=0.05) 1508.96 150896 1508 96 (1508.9 14815 148 15 ±148.1 N, N , N) p>0.05, p005 p p>0.05 (p>0.05) use (REST antioxidantstreated treated SA, (SA BL.

Resumo Este estudo teve como objetivo avaliar o efeito de soluções antioxidantes na resistência à fratura e resistência de união em dentes tratados endodonticamente e clareados (38% de peróxido de hidrogênio). Cento e oitenta espécimes de dentina foram obtidos, 60 para cada teste: resistência à fratura, espessura da camada híbrida e resistência de união. Os grupos (n=10) foram compostos aleatoriamente de acordo com o protocolo pós-clareamento: REST - restauração, sem clareamento; BL - clareamento + restauração; SA - clareamento, solução de ascorbato de sódio a 10% e restauração; AT - clareamento, solução de α-tocoferol a 10% e restauração; CRAN - clareamento, solução de cranberry a 5% e restauração; CAP - clareamento, solução de capsaicina 0,0025% e restauração. Os dados foram analisados com os testes ANOVA, Kruskal-Wallis, Dunn e Qui-Quadrado (α=0,05). Os maiores valores de resistência à fratura foram observados em REST (1508,96 ±148,15 N), sem diferença significativa para os grupos clareados (p>0,05), independente do uso de antioxidantes. A espessura da camada híbrida no grupo que não foi submetido ao clareamento (REST) foi significativamente maior do que em qualquer outro grupo. A resistência de união nos grupos clareado e tratado com antioxidantes (SA, AT, CRAN, CAP) não apresentou diferenças com o grupo branqueado sem antioxidantes (BL). As falhas adesivas foram predominantes nos grupos que não receberam a aplicação do antioxidante. Em conclusão, os antioxidantes avaliados não mostraram efeito sobre a resistência à fratura, espessura da camada híbrida ou resistência de união à dentina clareada após tratamento endodôntico. A aplicação de soluções de ascorbato de sódio 10%, alfa-tocoferol 10%, cranberry 5% ou capsaicina 0,0025% não é uma etapa eficaz e não deve ser considerada para os protocolos restauradores após clareamento não vital. 38% 38 (38 hidrogênio. hidrogênio . hidrogênio) obtidos 6 teste n=10 n10 n 10 (n=10 pósclareamento pós pós-clareamento restauração αtocoferol α tocoferol 5 00025 0 0025 0,0025 ANOVA KruskalWallis, KruskalWallis Kruskal Wallis, Wallis Kruskal-Wallis QuiQuadrado Qui Quadrado α=0,05. α005 α=0,05 05 (α=0,05) 1508,96 150896 1508 96 (1508,9 14815 148 15 ±148,1 N, N , N) p>0,05, p005 p p>0,05 (p>0,05) (REST SA, (SA BL.

Abstract The composition-processing-structure-properties relationship of Na2O-Al2O3-SiO2-based geopolymers containing calcium sources is critical for the design of enhanced ceramic binders. This work evaluated the addition of 1-6 wt% of calcium hydroxide (CH) to a metakaolin-based geopolymer (prepared with NaOH 12 M and colloidal silica suspension) and how it affected the performance of the prepared samples after thermal treatments up to 1000 °C. The setting time, mechanical strength, porosity, density, permanent linear change, and phase and bond type evolution of the specimens with temperature were analyzed. The incorporation of 3 or 6 wt% of CH into the designed composition led to a fast hardening of the mixtures (1.7 h), resulting in geopolymers with high green mechanical strength (18.9 to 23.9 MPa). Nepheline and albite generation in the samples containing 6 wt% of CH resulted in a ceramic with improved cold crushing strength (45.2 MPa) and lower linear shrinkage (-10.5%) when compared to the calcium-free composition. compositionprocessingstructureproperties processing structure properties Na2OAl2O3SiO2based NaOAlOSiObased Na2O Al2O3 SiO2 based Na O Al SiO binders 16 1 1- wt (CH metakaolinbased metakaolin suspension 100 C °C time porosity density change analyzed 1.7 17 7 (1. h, h , h) 18.9 189 18 9 (18. 239 23 23.

While opportunities for women to study at institutions of higher learning have increased compared to past generations, student mothers, specifically, are confronted with the extra burden of parenting, in combination with their academic work. Using an exploratory design within exploratory research, this study aimed to explore perceptions and experiences of student mothers enrolled at University of the Western Cape. We used a purposive sampling strategy to recruit female student mothers, who had at least one child and were registered for a full-time undergraduate degree at the institution. A total of 25 female students constituted four semi-structured focus groups, with five to seven participants in each. Thematic analysis was used to analyse the data, and Bronfenbrenner's Process-Person-Context-Time model was adopted, which allowed for a nuanced understanding of the student mother within various contexts. The study received ethics approval and institutional permission from the universities registrar and also adhered to good research ethical principles. Key themes relating to the challenges experienced by student mothers that we identified, included financial difficulties and the stress of balancing their dual responsibilities of being a student and a mother. Proximity to their children complicated their attempt to fulfil dual roles; proximity to the child facilitated a closer bond with the child(ren), but impeded their academic performance. Geographical distance from the child(ren) facilitated their performance as a student, but often at huge emotional expense from participants. Familial support was highlighted as an important facilitator of academic performance. Family members often assisted with care of the child, allowing the student mother to engage in her role as student. Some student mothers perceived a lack of support from the university, while others acknowledged it as their own responsibility to manage their commitments to study. Despite these difficulties, many student mothers found that motherhood was a motivator for them to study, to secure a positive future for themselves and their child(ren).
