Resumo Alternativas vêm sendo estudadas com o intuito de minimizar os grandes impactos ambientais provenientes da produção do cimento e aço. Inclusive, adotando cimentos compostos, com incorporação de materiais alternativos, diminuindo a necessidade de cimento nas misturas. Por conseguinte, este trabalho estudou a viabilidade de incorporação de resíduos siderúrgicos no desempenho mecânico e de durabilidade de argamassas, avaliando a substituição parcial e total do Cimento Portland por escória granulada de alto-forno moída (EGAF) e resíduo proveniente do processo de Dessulfurização de Gases de Combustão (FGD). Os resultados encontrados mostram que a associação desses resíduos em substituição ao cimento melhorou cerca de 40% o desempenho mecânico das argamassas. Além de apresentarem um menor módulo de elasticidade e menor absorção de água por capilaridade, propriedades que aumentam significantemente a durabilidade das matrizes. Os resultados de lixiviação de contaminantes não apresentaram nenhum contaminante em quantidade prejudicial. Os estudos apresentados demonstram que a utilização de FGD e EGAF simultâneos para substituir o Cimento Portland foram satisfatórios, obtendo desempenhos mecânicos e de durabilidade superiores aos de referência, viabilizando a utilização desses resíduos na produção de argamassas com baixo teor de cimento.

Abstract Alternatives have been studied in order to minimize the major environmental impacts arising from the production of cement and steel. Alternatives include adopting composite cements with the incorporation of alternative materials, to reduce the need for cement in the mixtures. Therefore, this study worked on the viability of incorporating steel residues in the mechanical performance of mortar and durability, evaluating the partial and total replacement of Portland Cement (PC) by granulated blast furnace slag (EGAF) and residue from the Desulfurization process of flue gases (FGD). The results found show that the association of these residues in place of cement improved the mechanical performance of the mortars by around 40%. In addition to having a lower modulus of elasticity and lower absorption of water by capillarity, properties that significantly increase the durability of the matrices. The contaminant leaching results did not show any contaminants in harmful amounts. The studies presented demonstrate that the simultaneous use of FGD and EGAF to replace Portland cement were satisfactory, obtaining better mechanical and durability performances than the reference ones, enabling the use of these residues in the production of mortars with low cement content.

Resumen La astrocitopatía autoinmune asociada a proteína ácida fibrilar glial (GFAP) fue descripta por primera vez en el año 2016. La manifestación clínica más frecuente es la meningoencefalomielitis asociado a un patrón imagenológico característico que permite la sospecha diagnóstica y su confirmación mediante la determina ción de los anticuerpos en suero y en líquido cefalorra quídeo (LCR). Presentamos el caso de una paciente de 35 años con compromiso del sistema nervioso a nivel central y periférico y un reciente diagnóstico de cáncer de tiroides, que frente al cuadro clínico compatible de meningoencefalomielitis, los hallazgos característicos en resonancia magnética y luego de la exclusión de enfermedades alternativas, finalmente se arribó al diag nóstico por la determinación positiva de anti GFAP en LCR. Realizó tratamiento quirúrgico y con iodo radio activo por su tumor hallado y posteriormente recibió tratamiento con corticoides con mejoría parcial de la signo-sintomatología neurológica. Destacamos que en esta enfermedad las imágenes por resonancia magnética presentan un patrón característico, aunque no patog nomónico, siendo necesario considerar otras causas. Ante una alta sospecha de esta entidad por el cuadro clínico e imagenológico, es conveniente realizar dosaje del anticuerpo en LCR, dada la mayor sensibilidad y especificidad en comparación con su pesquisa en suero, con el fin de arribar al diagnóstico etiológico definitivo como en el caso clínico presentado.

Abstract Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy was described for the first time in 2016. The most common clinical manifestation is menin goencephalomyelitis associated with a characteristic imaging pattern that allows diagnostic suspicion and its confirmation through determination of antibodies in serum and cerebrospinal fluid (CSF). We present a case of a 35-year-old patient with involvement of the central and peripheral nervous system and a recent diagnosis of thyroid cancer, which compared to the compatible clinical picture of meningoencephalomyelitis, characteristic findings on MRI and after the exclusion of alternative pathologies, we finally arrived at the diagnosis by the positive determination of anti-GFAP in CSF. The patient underwent surgical treatment and radioactive iodine for the diagnosed thyroid tumor and she subsequently received treatment with corticosteroids with partial improvement of the neurological symptomatology. We emphasize that in this pathology the MRI images usually depict a characteristic pattern, although not pathogno monic, it is necessary to consider other causes. Before a high suspicion of this entity due to the clinical and imaging picture, it is convenient to measure the anti body in CSF, given the greater sensitivity and specificity compared to its serum screening, in order to arrive to the definitive etiological diagnosis as it was done in the clinical case that is presented.

BACKGROUND: Maintaining or promoting employment in the presence of disability or reducing the impact of disability on employability should be the adopted focus to decrease the negative impact that disability has on the economy and just as important on the livelihood and well-being of exposed insured individuals. Group risk disability insurance protects an employee's income when illness or injury result in work disability. To achieve this, factors that promote the success of rehabilitation and support for return-to-work of employees following illness and injury need to be understood from an insurance perspective. OBJECTIVES: To explore principles of disability claims management during the rehabilitation and work reintegration stage using a multi-stakeholder approach for the purpose of successful return to work. METHODS: An exploratory qualitative design was used to collect data via semi-structured interviews with 26 purposively selected participants. Interviews were audio-recorded, data were transcribed and analysed thematically. Qualitative research was used to understand the necessary role players in the work reintegration process, factors that hinder and promote work reintegration and best practice principles for Disability Claims Management (DCM). RESULTS: Three themes emerged from the study; (i) role players and their functions with collaboration is integral to disability claims management, (ii) various factors promote and restrict return-to-work planning, and (iii) best practice principles in the DCM pathway that promote return-to-work. These principles include behavioural economics as the central principle, with resource identification and competency, governance, role engagement and education and awareness as supporting principles. CONCLUSION: Collaborative and integrated approaches by role players within a workers' family unit, health system, employer structure and insurance compensation are required for positive return-to-work outcomes. The various role players are responsible for creating policies, structures, intervention strategies, and environments that foster return-to-work. IMPLICATIONS FOR PRACTICE • An integrated approach is required for optimal RTW outcomes as employers' policies restrict work integration. • A collaborative approach by all role players involved in DCM, focusing on positive RTW outcomes is required in the RTW process • Occupational therapists can influence employer incapacity and disability policies in order to keep people employed and productive in the presence of medical conditions with the application of reasonable accommodations where necessary. • Occupational therapists are suitably positioned to outline workplace environment and other supports required to guide and support employees through rehabilitation and RTW and in ensuring that employees who can remain at work while on a partial or fully insured benefit, can engage optimally in aspects of work function.

Abstract The present research work was carried out in Zaruma´s underground workings, a city located in the province of El Oro in the southwest of Ecuador. Zaruma is a city that has been exploited since the 1500's, the urban center sits on a swarm of veins enriched with gold, the antitechnical exploitation has caused the appearance of sinkholes on the surface of the city, with the emergency that occurred in December 2021, partial remediation was carried out corresponding to the filling of the galleries and construction of plugs in order to avoid collapses in the urban area, for the execution of the remediation work required manpower, workers who entered the s underground galleries in which carbon monoxide (CO) was detected, the objective was evaluated the health effects based on the levels of exposure to carbon monoxide. The research methodology is a non-experimental, cross-sectional, descriptive study, with a sample of fifteen workers operating inside the mine, carbon monoxide measurements were taken in the mine workings and symptomatology interviews were applied to the workers taking aspects of age and time of exposure. The results describe that the operators presented symptoms: headaches, nausea, fatigue, weakness; the severity of the symptoms is a function of time and CO concentration. It´s concluded that exposure to CO in high concentrations for a period of time causes intoxication, with headache being the most frequent symptom.

Resumen El presente trabajo de investigación se desarrolló en las galerías subterráneas de Zaruma, ciudad ubicada en la Provincia de El Oro al Sur Oeste del Ecuador. Zaruma es una ciudad que ha sido explotada desde los años 1500, el casco urbano se asienta sobre un enjambre de vetas enriquecidas con oro, la explotación antitécnica ha provocado la aparición de hundimientos en la superficie de la ciudad, con la emergencia sucedida en diciembre del 2021, se realizó la remediación parcial que corresponde al relleno de la galerías y construcción de tapones con la finalidad de evitar colapsos en el casco urbano, para la ejecución de las obras de remediación se requirió de mano de obra, operarios quienes ingresaron a las labores subterráneas en las que se detectaron monóxido de carbono (CO), el objetivo evaluar los efectos en la salud en relación a los niveles de exposición a monóxido de carbono. Se ha aplicado una metodología de investigación no experimental, de corte transversal, descriptivo, con una muestra de quince trabajadores operativos interior mina, se realizó mediciones de monóxido de carbono en las labores mineras y se aplicó entrevistas de sintomatología a los operarios tomando aspectos de edad y tiempo de exposición. Los resultados describen que los operarios presentaron síntomas: cefaleas, náuseas, fatiga, debilidad, la severidad de los síntomas está en función del tiempo y concentración de CO. Se concluye que la exposición a CO en concentraciones altas por un periodo de tiempo causa intoxicación, siendo la cefalea el síntoma que se presenta como el más frecuente.

Abstract Concern about environmental degradation has been growing at an alarming rate, and as a result, companies have been pressured to apply technological processes that comply with environmental aspects, and green information systems are one of them. The objective of the study is to analyze how green information systems (GIS) influence environmental strategies and organizational performance in Mexican manufacturing companies. In the quantitative study, a second-order hierarchical model was analyzed using Partial Least Squares (PLS) Structural Equation Modelling. The collected sample consisted of 99 managers of medium and large companies by questionnaire. It was found that GISs play a crucial role in the growth of companies, as a tool to improve their operations and to the economic aspect by reducing costs, but at the same time, to environmental issues by having the ability to reduce the pollution emitted.

ABSTRACT Objective. To estimate the costs incurred in the control of Aedes aegypti in the Loreto region, during the years 2017 and 2018. Materials and methods. We conducted a partial retrospective economic evaluation of the costs of Aedes aegypti control of the Regional Health Directorate Loreto, during the implementation of the Regional Plan for Surveillance and Control of Aedes aegypti. Documentation such as plans, intervention reports and payment slips were reviewed, and interviews were conducted with professional personnel involved in vector control, on the costs of control interventions. Results. We found that the costs incurred in dengue vector control in the Loreto Region in the two years were: PEN 3,807,858 and PEN 4,066,380 during 2017 and 2018, respectively (USD 1,175,264 and USD 1,1210,232 at the 2017 and 2018 exchange rate). However, the effect of control activities is short-lived. Conclusions. The high cost involved in vector control with the methods currently used and the short duration of its effect make it unsustainable. Studies should be conducted in order to find other more efficient methods for dengue control.

RESUMEN Introducción: La industria biotecnológica nacional ha desarrollado terapias dirigidas al receptor de factor de crecimiento epidérmico, y una de ellas, es la vacuna CIMAvax-EGF como inmunoterapia activa y que se relaciona directamente con el incremento de la supervivencia global. Objetivo: Estimar la supervivencia de pacientes con cáncer de pulmón avanzado tratados con CIMAvax-EGF. Métodos: Se realizó un estudio observacional de cohorte retrospectiva en el Hospital Provincial Docente Oncológico María Curie de la provincia de Camagüey en el período comprendido entre los años de 2016 y 2018. El universo estuvo constituido por 32 pacientes que habían recibido quimioterapia con una evolución poco satisfactoria, donde se les aplicó el tratamiento con Cimavax-EGF y seguidos en la consulta de medicina oncológica. La fuente primaria de información fue la historia clínica individual de cada paciente. Los datos se procesaron a través del paquete estadístico Statistical Package for Social Sciences (SPSS) versión 26,0. Resultados: Predominaron los pacientes de 70 a 79 años, del sexo masculino, del subtipo histológico carcinoma epidermoide y los estadios clínicos IIIB y IVA. La supervivencia global y libre de progresión fue de 12,4 y 6,7 meses en ese orden. La respuesta al tratamiento de primera línea predominante fue la remisión parcial y la reacción adversa más frecuente registrada en los pacientes inmunizados fue el dolor en el sitio de la inyección. Conclusiones: En los pacientes que tuvieron una respuesta completa a la primera línea de tratamiento, mejoró la probabilidad de supervivencia al recibir el tratamiento de mantenimiento con la vacuna CiMAvax-EGF.

ABSTRACT Introduction: The national biotechnology industry has developed therapies directed at the epidermal growth factor receptor, and one of them is the CIMAvax-EGF vaccine as an active immunotherapy that is directly related to increasing overall survival. Objective: To estimate the survival of patients with advanced lung cancer treated with CIMAvax-EGF. Methods: A retrospective observational cohort study was carried out at María Curie Oncological Teaching Provincial Hospital in Camagüey province from 2016 to 2018. The universe consisted of 32 patients who had received chemotherapy with unsatisfactory evolution, where they were treated with Cimavax-EGF and followed up in the oncology medicine consultation. The primary source of information was the individual medical record of each patient. The data were processed using Statistical Package for Social Sciences (SPSS) version 26.0. Results: Patients aged 70 to 79 years, male, with the histological subtype squamous cell carcinoma and clinical stages IIIB and IVA predominated. Overall and progression-free survival was 12.4 and 6.7 months in that order. The predominant response to first-line treatment was partial remission and the most frequent adverse reaction recorded in immunized patients was pain at the injection site. Conclusions: In patients who had complete response to the first line of treatment, the probability of survival improved when receiving maintenance treatment with CiMAvax-EGF vaccine.

Om neologismes by te voeg by 'n woordeboek in die hersiening daarvan, help om die woordeboek bygewerk te hou, wat relevant is vir 'n aanleerderswoordeboek soos Oxford Advanced Learner's Dictionary (10de uitgawe) (voortaan OALD 10), die jongste uitgawe. Engelse aanleerderswoordeboeke soos OALD 10 word gereeld hersien. In hierdie artikel word die neologismes wat in OALD 10 ingesluit is, vanuit verskillende perspektiewe benader. Betreffende die woordsoort is 71.1% van die neologismes selfstandige naamwoorde, wat die naamwoordelike aard van Engels bevestig. Inhoudswoorde soos selfstandige naamwoorde, adjektiewe, bywoorde en werkwoorde beslaan ongeveer 96% van die neologismes. Te oordeel na woordvorming is, in dalende volgorde, die drie belangrikste metodes waarmee neologismes gevorm word samestelling, afleiding en samesmelting. Volgens die vorm wat die samestellings, wat meestal selfstandige naamwoorde is, aanneem, is hulle in dalende volgorde oop, koppelteken- en geslote samestellings. 623 samestellings vorm meer as die helfte van die neologismes wat kragtige bewys bied dat samestelling die mees frekwente metode is wat gebruik word om neologismes te vorm. Betreffende neologismes wat deur afleiding gevorm is, is die meeste ook selfstandige naamwoorde. 170 uit 300 neologismes wat deur afleiding gevorm is, het reeds as afleidings van trefwoorde in OALD 9 verskyn. Rakende 34 samesmeltings is 75% van hulle gedeeltelik van aard, wat daarop dui dat ten minste een woord tydens die skep van 'n samesmelting in sy volledige vorm is. Betreffende die nuwe woorde met streeketikette is byna 80% geëtiketteer as behorende tot Britse en Noord-Amerikaanse gebruike, 'n aanduiding van die verskuilde Anglo-sentrisiteit. Die status van sommige woorde wat as neologismes beskou word, is betwisbaar, aangesien hulle lank reeds gebruik word. Die impak van die wetenskap en tegnologie op die insluiting van neologismes in OALD 10 is taamlik duidelik. Daar is steeds heelwat ruimte vir verdere navorsing rakende OALD 10.

Adding neologisms to a dictionary in its revision helps keep it abreast of time, which applies to a learner's one like Oxford Advanced Learner's Dictionary (10th edition) (henceforth OALD 10), its latest edition. English Learner's dictionaries like OALD 10 get revised regularly. In this article, the neologisms included in OALD 10 have been approached from different perspectives. In terms of the part of speech, 71.1% of the neologisms are nouns, which could speak for the nouny nature of English. Content words like nouns, adjectives, adverbs and verbs make up almost 96% of the neologisms. Judging by the word-formation, the top three ways to form the neologisms are compounding, derivation and blending in decreasing order. According to the form the compounds take, which are mostly nouns, the open, hyphenated and tight ones come in decreasing order. 623 compounds make up more than half of the neologisms, which provides strong evidence for compounding to be the most frequently used way of creating neologisms. For neologisms formed by derivation, most of them are also nouns. However, 170 out of 300 neologisms formed by derivation have already appeared as derivatives of headwords in OALD 9. For 34 blends, 75% of them are partial in nature, which means at least one word in making a blend is in its full form. When it comes to the new words with regional labels, nearly 80% are labeled as belonging to British and North American usages, a sign of the hidden Anglo-centrism. The status of some words counted as neologisms is questionable, as they have been in use for a very long time. The impact of science and technology on the inclusion of neologisms in OALD 10 is quite visible. There are still many opportunities for further exploration concerning OALD 10.

PURPOSE: This study aims to analyse the position of 155 hotel managers in Africa and Asia about implementing sustainability practices (SP) focussing their competitive advantage (CA). Sustainability practices and CA are explained through the technology-organisation-environment (TOE) framework within the hospitality, tourism and travel industries. DESIGN/METHODOLOGY/APPROACH: The Structural Equation Model based on Partial Least Squares (SEM-PLS) methodology was applied to hotels in African countries, including South Africa, as well as Asia. Six variables were analysed in order to study the impact of SP in CA. FINDINGS/RESULTS: Findings imply that technological advancements, organisational commitments and environmental considerations collectively foster robust SP in emerging economies. The adoption of eco-friendly technologies (TS), the integration of sustainable policies (OS) and adherence to environmental regulations (ES) collectively contribute to the sustainability goals of hotels. PRACTICAL IMPLICATIONS: The study reveals that hotels in emerging markets should strategically emphasise the TOE framework to enhance SP and CA. Investing in advanced technologies, implementing effective organisational practices and adhering to environmental standards significantly improve sustainability performance. ORIGINALITY/VALUE: While the TOE model has been extensively studied across various industries, limited research has explored its application in tourism. This study uniquely investigates how SP can enhance CA in the tourism sector through comparative analysis.

Abstract: The Court of Justice of the European Union (“CJEU”) has requested a modification of its Statute to address the challenges arising from an increasing workload. The aim is to redefine the competence of the EU courts in order to enable them to continue to fulfill, within a reasonable time, the mission assigned to them by the drafters of the Treaties in Article 19(1) of the EU Treaty. (“TEU”), namely, ensuring that “the law is respected in the interpretation and application of the Treaties.” The reform specifically provides for a partial transfer of interpretative powers to the General Court (“TG”), combined with the power of the CJEU to deal with matters of particular relevance. Furthermore, the possibility of bringing an appeal to the CJEU will be limited if the appeal boards of the EU agencies have already carried out a legal review in the first instance. A number of safeguards will avoid a situation where the sharing of the workload between two different courts could have a negative effect on the uniformity and consistency of case law.

Résumé: La Cour de justice de l'Union européenne («CJUE») a demandé une modification de son statut afin de faire face aux défis découlant d'une charge de travail croissante. L’objectif est de redéfinir la compétence des juridictions de l’Union européenne afin de leur permettre de continuer à remplir, dans un délai raisonnable, la mission qui leur a été assignée par les rédacteurs des traités, conformément à l’article 19, paragraphe 1, du traité UE («TUE»), à savoir veiller à ce que « le droit soit respecté dans l’interprétation et l’application des traités». La réforme prévoit spécifiquement un transfert partiel des pouvoirs d’interprétation au Tribunal («TG»), ainsi que la compétence de la CJUE de traiter des questions particulièrement pertinentes. En outre, la possibilité de faire appel devant la CJUE sera limitée si les chambres de recours au sein des agences de l'UE ont déjà procédé à un contrôle juridictionnel en première instance. Un certain nombre de garanties permettront d'éviter une situation dans laquelle le partage de la charge de travail entre deux juridictions différentes pourrait avoir un effet négatif sur l'uniformité et la cohérence de la jurisprudence.

Resumo: O Tribunal de Justiça da União Europeia (“TJUE”) solicitou uma alteração do seu Estatuto para fazer face aos desafios decorrentes de uma carga de trabalho crescente. O objetivo é redefinir a competência dos tribunais da UE, a fim de lhes permitir continuar a cumprir, num prazo razoável, a missão que lhes foi atribuída pelos redatores dos Tratados no artigo 19.º, n.º 1, do Tratado UE (“TUE”), nomeadamente, garantir que “a lei é respeitada na interpretação e aplicação dos Tratados”. A reforma prevê especificamente uma transferência parcial de competências interpretativas para o Tribunal Geral (“TG”), combinada com a competência do TJUE para tratar de questões de particular relevância. Além disso, a possibilidade de interpor recurso para o TJUE será limitada se as comissões de recurso das agências da UE já tiverem realizado uma revisão jurídica em primeira instância. Uma série de salvaguardas evitarão uma situação em que a partilha da carga de trabalho entre dois tribunais diferentes possa ter um efeito negativo na uniformidade e na coerência da jurisprudência.

Resumen: El Tribunal de Justicia de la Unión Europea (“TJUE”) ha solicitado una modificación de su Estatuto para hacer frente a los retos derivados de una carga de trabajo cada vez mayor. El objetivo es redefinir la competencia de los órganos jurisdiccionales de la UE con el fin de permitirles seguir cumpliendo, en un plazo razonable, la misión que les han asignado los redactores de los Tratados en el artículo 19, apartado 1, del Tratado de la UE (“TUE”), a saber, garantizar que “en la interpretación y aplicación de los Tratados se respete el Derecho”. La reforma prevé concretamente una transferencia parcial de las competencias interpretativas al Tribunal General (“TG”), combinada con la facultad del TJUE de tratar asuntos de especial relevancia. Además, la posibilidad de interponer un recurso ante el TJUE se limitará si las salas de recurso de las agencias de la UE ya han llevado a cabo una revisión jurídica en primera instancia. Una serie de salvaguardias evitarán una situación en la que el reparto de la carga de trabajo por dos órganos jurisdiccionales distintos pueda tener un efecto negativo en la uniformidad y coherencia de la jurisprudencia.

RESUMO Um dos procedimentos odontológicos mais comuns é a extração dentária, contudo, , o defeito ósseo decorrente do processo é apenas parcialmente restaurado, levando a uma perda ossea volumétrica consideravel. Para reabilitar um paciente totalmente ou parcialmente desdentado, devemos manusear estes sitios com intervenções cirúrgicas delicadas. Há uma vasta literatura apresentando tentativas de transpor os efeitos negativos de uma extração dentária, com o objetivo de diminuir a perda volumétrica tecidual ou restaurar a arquitetura alveolar. Neste contexto, a Terapia de Extração Parcial (TEP) representa um subgrupo de intervenções para prevenir a perda óssea após exodontia, usando o próprio dente para prevenir a perda óssea alveolar. Essa revisão de literatura tem por objetivo fazer um levantamento dos artigos publicados sobre as TEP, com ênfase na técnica de socket shield, e explanar a cerca das demais técnicas como sepultamento radicular, pontic-shield e proximal socket-shield, suas indicações e contra-indicações, a fim de aprofundar o conhecimento dessas técnicas. Para a identificação dos estudos inclui?dos ou considerados, adotamos a estrate?gia de busca detalhada para os bancos MEDLINE e Biblioteca Cochrane nos u?ltimos 31 anos, cujo idioma fosse o ingle?s, espanhol ou o portugue?s. Este texto, apresenta uma análise de dados atuais a respeito das alternativas para a preservação alveolar e instalação de implantes imediatos nestas áreas, apresentando a possibilidade de uma técnica cirúrgica diferenciada. No entanto, devido a imaturidade e falta de comprovação cientifica contundente a respeito da previsibilidade dos procedimentos, considera-se que o emprego da técnica de socket shield deve ser feito de forma cautelosa.

ABSTRACT One of the most common dental procedures is tooth extraction; however, the bone defect resulting from the process is only partially restored, leading to considerable bone loss. To rehabilitate a fully or partially edentulous patient, we must handle these sites with delicate surgical procedures. There is a large literature presenting attempts to overcome the negative effects of a dental extraction, with the aim of reducing tissue volume loss or restoring the alveolar architecture. In this context, Partial Extraction Therapy (PET) represents a subgroup of interventions to prevent bone loss after extraction using the tooth itself to prevent alveolar bone loss. This literature review aims to make a survey of the published articles on PET, with an emphasis on socket shield technique, and to explain the other techniques such as root burial, pontic-shield and proximal socket-shield, their indications and counter indications in order to deepen the knowledge of these techniques. To identify the included or considered studies, we adopted a detailed search strategy for MEDLINE and Cochrane Library focused in the last 31 years, whose language was English, Spanish or Portuguese. This text presents an analysis of current data regarding the alternatives for alveolar preservation and the installation of immediate implants in these areas, presenting the possibility of a different surgical technique. However, due to the immaturity and lack of conclusive scientific evidence regarding the predictability of the procedures, it is considered that the use of the socket shield technique must be done in an extremely cautious way.

Resumo Em percursos formativos com futuros/as professores/as de língua francesa, foi observado o apagamento da criticidade em planejamentos de sequências didáticas que envolvem a busca, seleção, análise, adaptação, organização e compartilhamento de materiais digitais ( Deschaine; Sharma, 2015 ). Tal problemática será discutida neste artigo, que visa explicitar limites e possibilidades nos processos de curadoria e criação de recursos técnico-pedagógicos para a educação linguística. Os resultados das análises até o momento realizadas apontam que as fontes às quais permanentemente recorrem aqueles estudantes na preparação de seus planos de aula (vídeos e podcasts instanciados em portais midiáticos e em plataformas de streaming ) podem inviabilizar o desenho didático ético, estético ( Rocha, 2019 ) e decolonial ( Veronelli; Daitch, 2021 ) de experiências de ensino-aprendizagem para a expansão de repertórios em línguas. Com o intuito de compreender o problema descrito, pretende-se, para além da discussão dos resultados parciais de duas pesquisas em andamento, apontar a necessidade de criarmos referenciais teórico-metodológicos que possam decolonizar a curadoria-autoria de materiais nesse campo, desde a formação de educadores/as à sua atuação em comunidades de aprendizagem.

Abstract In formative pathways with future French language teachers, the erasure of criticality in the planning of didactic sequences involving the search, selection, analysis, adaptation, organization, and sharing of digital materials has been observed ( Deschaine; Sharma, 2015 ). This issue will be discussed in this article, which aims to elucidate the limits and possibilities in the processes of curation and creation of technical-pedagogical resources for language education. The results of the analyses conducted so far indicate that the sources to which those students constantly resort in preparing their lesson plans (videos and podcasts instantiated on media portals and streaming platforms) can hinder the ethical, aesthetic ( Rocha, 2019 ), and decolonial ( Veronelli; Daitch, 2021 ) didactic design of teaching-learning experiences for the expansion of language repertoires. In order to understand the described problem, in addition to discussing the partial results of two ongoing research projects, we intend to highlight the need to create theoretical-methodological frameworks that can decolonize the curation-authorship of materials in this field, from the training of educators to their work in learning communities.

Resumo Foram abordados neste estudo micro concretos autoadensáveis ecoeficientes com substituição parcial do cimento Portland por resíduo de rochas ornamentais (do inglês ornamental stone waste - OSW) e substituição dos agregados convencionais por resíduo de poliestireno expandido. A dosagem foi feita utilizando metodologia de empacotamento de partículas, e as frações de substituição seguiram um projeto experimental estatístico composto de segunda ordem. Foram avaliados e discutidos os parâmetros reológicos, físicos, mecânicos e de ecoeficiência das misturas. Como esperado, a incorporação dos resíduos diminuiu a resistência mecânica, e as misturas com elevadas incorporações de agregados leves apresentaram tendência a segregação. Entretanto, a adição do resíduo OSW demonstrou aumentar a trabalhabilidade e diminuir a viscosidade, contribuindo para controlar a segregação devido à redução no consumo de água necessário sem prejudicar a fluidez da mistura. Ao mesmo tempo, o agregado leve diminuiu tanto a densidade das misturas quanto a viscosidade. A interação do resíduo com o agregado leve se mostrou promissora na obtenção de microconcretos leves mais ecoeficientes.

Abstract Eco-efficient self-compacting micro concretes with partial replacement of Portland cement by ornamental stone waste (OSW) and replacement of conventional aggregates by expanded polystyrene waste were addressed in this study. A base mixture was obtained using a particle packing method, and replacement fractions followed a second-order composite experimental design. The mixtures’ rheological, physical, mechanical and eco-efficiency parameters were evaluated and discussed. As expected, the incorporation of residues reduced the mechanical strength, and mixtures with high incorporation of lightweight aggregates tended to segregate. However, OSW has been shown to increase workability and decrease viscosity, contributing to control segregation due to the reduced amount of water required without impairing the fluidity of the mix. At the same time, the lightweight aggregate decreased both the density of the mixtures and the viscosity. The interaction of the residue with the lightweight aggregate proved promising in obtaining more eco-efficient lightweight microconcretes.
