Exploring the conceptualisation of locative events in French, English, and Dutch: Insights from eye-tracking on two memorisation tasks
Authors: Lesuisse Mégane
Published: November 2022

The present study addresses the influence of language on the conceptualisation of locative events (e.g., the bottle on the table) in French, English, and Dutch which differ greatly in their habitual encoding of locative events. Dutch obligatorily expresses the disposition of the Figure (viz. the bottle) via a Cardinal Posture Verb (CPV) like liggen ‘lie’, staan ‘stand’, or zitten ‘sit’. In French, the preferred locative marker is the neutral copula être ‘be’ which leaves dispositional nuances habitually unexpressed. English straddles the middle: while the neutral copula be is usually preferred, the CPVs are sometimes found because of diachronic reasons. Our study assesses the potential repercussions of these cross-linguistic differences on the perception of locative events via a recognition task involving eye-tracking and is run in a non-verbal and a verbal condition. Our findings show that, irrespective of the condition, recognition performance is affected by the linguistic preferences, which confirms the permanent effect of language on thought even beyond verbal contexts. The analysis of eye-movements corroborates this finding: depending on their language, the participants attend to the stimuli differently. In the verbal condition, language is used as a strategic tool to enhance memorisation and the participants’ eye-movements still reflect cross-linguistic differences.
Mode manipulation in a ring–core fiber for OAM monitoring and conversion

Published: November 2022

The monitoring and conversion of photonic orbital angular momentum (OAM) play fundamental and important roles for both classic and quantum technologies, especially in low-loss transmission media such as ring-core fibers (RCFs), which make many OAM applications practical or vastly more flexible. However, in a RCF, the modes associated with different OAM states are highly overlapping due to the circular refractive index distribution structure, which makes it difficult to distinguish and monitor the OAM modes and in turn limits its inline conversion. Here, we report the first experimental realization of mode monitoring in a RCF using mode filters (MFs), which takes advantage of the difference in the mode adiabatic evolution and the higher-order mode cutoff conditions in tapered RCFs. Different-order OAM can be filtered using MFs with different geometric parameters, as demonstrated by the linearly polarized mode intensity. Combined the mode manipulations in RCF and single-mode fiber, the fundamental mode coupling efficiency can reach 90%, the RCF mode conversion monitoring through inline transmission spectrum evolution can be realized, and the inline fabrication of RCF grating, which couples one mode to a desired mode, can be demonstrated by the fabricating process of three long-period fiber gratings. The mode conversion efficiency between 0-order and 1, 2- or 3-order OAM modes exceeds 96%. Our work provides an efficient approach to monitor and convert OAM modes in higher-order mode supporting RCFs and even other special fibers and further promotes the improvement of the capacity of OAM transmission in RCFs.
Recent advances in quantum nanophotonics: plexcitonic and vibro-polaritonic strong coupling and its biomedical and chemical applications
Authors: Kim Yangkyu , Barulin Aleksandr , Kim Sangwon , Lee Luke P. , Kim Inki
Published: November 2022

The fundamental understanding of molecular quantum electrodynamics via the strong light–matter interactions between a nanophotonic cavity and quantum emitters opens various applications in quantum biology, biophysics, and chemistry. However, considerable obstacles to obtaining a clear understanding of coupling mechanisms via reliable experimental quantifications remain to be resolved before this field can truly blossom toward practical applications in quantitative life science and photochemistry. Here, we provide recent advancements of state-of-the-art demonstrations in plexcitonic and vibro-polaritonic strong couplings and their applications. We highlight recent studies on various strong coupling systems for altering chemical reaction landscapes. Then, we discuss reports dedicated to the utilization of strong coupling methods for biomolecular sensing, protein functioning studies, and the generation of hybrid light–matter states inside living cells. The strong coupling regime provides a tool for investigating and altering coherent quantum processes in natural biological processes. We also provide an overview of new findings and future avenues of quantum biology and biochemistry.

Authors: Liu Huiyu , Xing Xiaotong , Tan Yan , Dong Haifeng
Published: November 2022

As a “star material”, 2D transition metal carbides and/or nitrides (MXenes) have tremendous potential applications in biosensor development and molecular imaging. MXenes have a lot of advantages due to their large specific surface, excellent electrical conductivity, adjustable band gap, and easy modification. MXenes that immobilized with DNA strands, proteins, enzymes, or other bioluminescent materials on the surface, have been used to measure small molecules with extraordinary sensitivity and remarkable limit of detection. This review provides an overview of most recent development in the synthesis, fundamental properties, biosensing, and molecular imaging applications of MXenes. We focused on molecular detection through MXene-based electrochemical properties their challenges and novel opportunities of MXenes in biological applications. This article will provide a guide for researchers who are interested in the application of MXenes biosensors.
DNA as grabbers and steerers of quantum emitters

Published: November 2022

The chemically synthesizable quantum emitters such as quantum dots (QDs), fluorescent nanodiamonds (FNDs), and organic fluorescent dyes can be integrated with an easy-to-craft quantum nanophotonic device, which would be readily developed by non-lithographic solution process. As a representative example, the solution dipping or casting of such soft quantum emitters on a flat metal layer and subsequent drop-casting of plasmonic nanoparticles can afford the quantum emitter-coupled plasmonic nanocavity (referred to as a nanoparticle-on-mirror (NPoM) cavity), allowing us for exploiting various quantum mechanical behaviors of light–matter interactions such as quantum electrodynamics (QED), strong coupling (e.g., Rabi splitting), and quantum mirage. This versatile, yet effective soft quantum nanophotonics would be further benefitted from a deterministic control over the positions and orientations of each individual quantum emitter, particularly at the molecule level of resolution. In this review, we will argue that DNA nanotechnology can provide a gold vista toward this end. A collective set of exotic characteristics of DNA molecules, including Watson-Crick complementarity and helical morphology, enables reliable grabbing of quantum emitters at the on-demand position and steering of their directors at the single molecular level. More critically, the recent advances in large-scale integration of DNA origami have pushed the reliance on the distinctly well-formed single device to the regime of the ultra-scale device arrays, which is critical for promoting the practically immediate applications of such soft quantum nanophotonics.
Manipulating light scattering and optical confinement in vertically stacked Mie resonators
Authors: Vennberg Felix , Ravishankar Ajith Padyana , Anand Srinivasan
Published: November 2022

High index dielectric nanoresonators have gained prominence in nanophotonics due to lower losses compared to plasmonic systems and their ability to sustain both electric and magnetic resonances. The resonances can be engineered to create new types of optical states, such as bound-states in a continuum (BIC) and anapoles. In this work, we report on the optical properties of vertically stacked AlGaAs nanodisk Mie resonators. The nanodisks are designed to support an anapole state in the visible wavelength region (400–700 nm). The vertically stacked nanodisk resonators are fabricated from AlGaAs/GaAs multilayer samples with a fast and scalable patterning method using charged sphere colloidal lithography. Both measurements and finite difference time domain (FDTD) simulations of two and three stacked resonators show a sharp dip in the reflectance spectra at the anapole wavelength. For the 2 and 3 disk stacks the reflectance dip contrast at the anapole wavelength becomes very pronounced in the specular reflectance and is attributed to increased directional scattering due to an antenna effect. FDTD simulations show there is enhanced field confinement in all the disks at the anapole wavelength and the confined energy within the individual disks in the stack is at least 2–5 times greater compared to an isolated single nanodisk of the same dimension. Furthermore, the field confinement consistently increases with adding more disks in the stack. These vertically stacked AlGaAs nanodisk resonators can be a very exciting platform to engineer light matter interactions for linear and non-linear optical applications. The general principles of the fabrication method can be adapted to other wavelength ranges and can also be adapted for other III–V material combinations as well as for Si/SiO2.
"A Lovelorn Orphan in a Cold World": Bertrand Russell's 1931 North American Lecture Tour
Authors: Stevenson Michael D. , Brown Sarah-Jane
Published: November 2022

Bertrand Russell undertook an extended North American lecture tour in 1931 to raise funds for the Beacon Hill experimental school he operated with Dora Russell. To rectify the existing lack of scholarly analysis of the 1931 tour, this paper provides annotated transcriptions of twenty-eight letters Russell sent during the tour to Dora and to Patricia Spence, Russell’s mistress. These letters provide intriguing insights into the state of Russell’s financial and professional affairs and illuminate personal relationships he cultivated in the United States and Canada. Most importantly, they document his complex marital situation at this tumultuous juncture in his life before he decided to end his relationship with Dora early in 1932 in favour of Spence.
Is Motion “Contradiction’s Immediate Existence”?
Authors: Stevens Graham , Rush Michaael
Published: November 2022

A driving concern of Russell’s rejection of Idealism was his conviction that reality is free of contradictions. However, echoing the neo-Hegelians that Russell is usually taken successfully to have refuted, Graham Priest has argued that the analysis of motion provides a motivation to adopt dialetheism (the thesis that some contradictions may be true). Furthermore, Priest argues that the Russellian account of motion as given in The Principles of Mathematics fails accurately to capture the phenomenon. In this paper we argue that Priest’s objections to Russell are neither new nor decisive. We show that even if one shares Priest’s concerns about the Russellian model there are alternatives inspired by Russell’s own contemporaries that do not entail dialetheism. We conclude that not only are Priest’s objections to Russell unconvincing, but even one who shares Priest’s intuitions has no reason to resurrect the Hegelian account of motion.

Performance Evaluation of Two System Models for a MIMO System to Hover the Bicopter Unmanned Aerial Vehicle
Authors: Prakosa Jalu Ahmad , Agmal Swivano , Kurniawan Edi , Kholili Muhammad Jauhar , Astuti Chifayah
Published: November 2022

Building unmanned aerial vehicle (UAV) control system models are highly challenging due to multiple inputs and multiple outputs (MIMO). Not only does it have various angular position outputs such as roll, yaw, and pitch, but also flight control has more than one input; for instance, a bicopter has dual rotors. More rotors have more complex model. The hover condition has a zero resultant force which can be utilized to design a system model. On the other hand, an attractive identification system method is applied to develop the design. This research aims to evaluate the performance of two MIMO design on bicopter between methods based on the hover principle and identification technique. Experimental validation by employing bicopter simulator is an excellent strategy to fulfil this purpose. The results of the investigation of the experiment showed that the identification model was more accurate than the hover design, particularly regarding the overshot phenomenon and error. In addition, the hover principle tended to build ideal model because it did not include the dynamic, uncertainty and nonlinear conditions in aeroplane control design.  Although the identification system was complicated because it previously needed to measure the input and output values, it performed closer to the actual experiment. It performed more satisfactory overshoot values compared with the experimental validation than the hover model by 1°, 3°, and 8° in roll, pitch, and yaw angles, respectively.

Basic Sciences Medical Faculty and Their Challenges to Compassionate Teaching
Authors: Elliott Gail E.
Published: November 2022

Basic sciences teaching faculty are important in combatting the mental health issues facing M1/M2 medical students. These faculty are key in helping students through the basic sciences by identifying those that are struggling, guiding them to necessary resources, reassuring them that they can attain their qualifications, and encouraging them to engage in active learning. Many of these faculty also fulfill official mentorship roles within the curriculum and advise students on academic and career aspects of their medical school pathway. However, faculty are also overwhelmed by institutional expectations (e.g., research) and student considerations (e.g., poor behavior, negative teaching evaluations). The result is that faculty are struggling to balance all these expectations, with negative experiences such as inappropriate student behavior and toxic academia severely affecting faculty and leading to a noticeable increase in instances of faculty burnout and compassion fatigue. With self-isolation and remote learning, many of these issues (e.g., poor student behavior) are likely to worsen and as a result, institutions need to reevaluate these issues to develop measures to protect faculty and allow them to do their job properly, prioritizing medical students and guiding them effectively through the first two years of the rigorous medical curriculum.
Predictors and Effects of the Economic Consciousness of the Indigenous Peoples of the North

Published: November 2022

Globalization and its consequences have had a noticeable impact on the lives of the indigenous peoples of the North, including their economic behavior. Due to geographical and social isolation, studies of the economic consciousness of the Northern peoples are limited. This article seeks to fill this gap through the study of predictors and effects of the economic consciousness of the Northern peoples. Structural equation modeling revealed various types of economic consciousness of the Northern peoples, as well as their predictors, both internal (attitude to time, values) and external (culture, gender, age) contribute differently to the formation of subjective economic well-being. The most significant and positive contribution is made by a balanced strategy of economic behavior, which assumes an optimal ratio of savings, investments and activity, reliance on financial knowledge in making economic decisions, a high level of self-regulation and self-control in the economic sphere. The increased importance of material values, the willingness to receive them at the expense of health and vocation, combined with distrust of financial institutions and actors, on the contrary, reduces the level of subjective economic well-being. The developed model offers directions for the transformation of the economic behavior of the indigenous peoples of the North.

Authors: Kızılyıldırım Suna , Köksal Fatih , Güneri Cansu Önlen
Published: November 2022

Group A streptococci are important pathogens with various virulence factors, such as M protein, superantigens, hemolysins, deoxyribonuclease, and proteases. The aims of this study are to investigate the detection of emm genotypes and other virulence genes, such as SAgs, DNase, protease, antibiotic resistance, and phylogenetic relationships in GAS strains isolated from clinical samples.

Test strains were obtained from Çukurova University Balcalı Hospital and regional hospitals in Adana province. The M proteins were detected by sequence analysis of emm genes. SAgs and other virulence gene profiles were determined using the Multiplex-PCR method. The antibiotic susceptibility of the isolates was performed by the disc diffusion method and evaluated according to CLSI criteria. The PFGE method was used to determine the clonal relationship between the strains.

The emm gene was positive in 86 isolates. The most common emm genotypes were emm28 (22%), emm1 (18.6%), emm12 (13.9%), and emm3 (11.6%). Also, the most common virulence genes were speG (58.1%), speC (56.9%), sdaB (53.4%), and mac (53.4%). The rates of resistance to erythromycin, clindamycin, levofloxacin, ciprofloxacin and telithromycin were 19.8%, 16.3%, 4.7%, 3.5%, and 3.5%, respectively.

As a result, additional regional studies on the detection and prevalence of GAS virulence factors in Turkey are required. We believe that this study will provide valuable information for epidemiological studies on emm sequences, Sags, and other virulence factors of Streptococcus pyogenes in Turkey.

Y en la segunda fase metodológica, se analizaron las intervenciones de enfermería (NIC) que las matronas efectúan en paritorio durante su jornada asistencial. Resultados: El 90,3% de las matronas presentan sobrecarga en el trabajo, pues para el 80,6% el ratio matrona- gestante no se encuentra bien establecido; pues tiempo medio de ejecución de una intervención de enfermería (NIC), es de 20 minutos. Por ello, el 100% de la muestra considera de máxima utilidad el desarrollo de herramientas de medición de cargas de trabajo. Conclusiones: Se ratifica la necesidad de generar un instrumento que considere la diversidad de intervenciones de enfermería (NIC) que desarrollan dentro del paritorio.
A atuação do empresário no executivo municipal apresenta melhores resultados?
Authors: Pereira Helder Marcos Freitas , Saes Maria Sylvia Macchione
Published: November 2022

Resumo O objetivo deste artigo é levantar as características demográficas dos prefeitos eleitos, enfatizando os candidatos que se declaram empresários, e analisar se esse perfil tem melhores resultados quanto ao desempenho, medidos com base na situação fiscal e no Índice de Educação Básica (IDEB) do município. Para tanto, o trabalho foi dividido em duas partes. Na primeira, por meio de regressão logística, buscou-se encontrar o perfil do candidato eleito, centrando-se no fato de ele ser empresário. Na segunda seção do artigo, com o emprego da metodologia de regressão multinível, foi analisado se tal perfil escolhido pelos eleitores era responsável por um desempenho superior. Com relação aos resultados, apesar de os empresários constituírem a maioria entre os candidatos, essa característica não foi significativa para o sucesso eleitoral. Na segunda parte da pesquisa, de modo geral os resultados não encontraram correlação entre o perfil dos eleitos e o desempenho da gestão municipal. Somente a idade do prefeito foi significativa na questão fiscal dos municípios. Dessa forma, os empresários não apresentam resultados diferentes da média, o que permite pressupor que esse grupo não tem melhores habilidades e julgamentos.
A brief trajectory of the constituent elements of the Advocacy Coalition Framework (ACF)
Authors: Oliveira Henrique Campos de , Sanches Filho Alvino
Published: November 2022

Abstract This paper aims to retrace the trajectory of the Advocacy Coalition Framework (ACF), especially its policy-oriented learning process. Initially, we contrast the elements in Sabatier and Mazmanian (1980), where the first efforts to develop an analysis model are found, with the arguments found in Sabatier (1987, 1988, and 1993). Subsequently, the historical trajectory of updates and versions of the model is discussed based on the analyses in Sabatier and Jenkins-Smith (1999), Sabatier and Weible (2007), and Jenkins-Smith et al. (2018). It was possible to follow the modifications in the model, the main hypotheses built, the criticisms, and their unfoldings. As main findings, it was evident throughout the ACF construction trajectory: four versions of the model over almost 30 years and with the decisive participation of six prominent authors who contributed to its main developments since the first version, present in Sabatier and Jenkins-Smith (1993); and Sabatier and Jenkins-Smith (1999), the model gains greater analytical capacity with the intermediate variables between the external factors and the policy subsystem and analytically refines the categories internal to the subsystem. One gap identified in this trajectory, and consequent proposal for a future research agenda, is the influence of international actors and their implications on policy modifications, a condition not explicitly addressed by the ACF in its varied versions, as highlighted by Jenkins-Smith et al. (2018).

Published: November 2022

Neste trabalho é proposto um método para medição da velocidade do som que faz uso de um aparato de baixo custo. O experimento utiliza um tubo semiaberto de PVC como cavidade acústica e um aplicativo gratuito de celular que detecta e processa o som emitido por este tubo ao ser preenchido com água a uma taxa constante. A partir do modelo físico que descreve as frequências ressoantes desse sistema, as componentes espectrais do som produzido pela cavidade foram analisadas e a velocidade do som a 25 ∘C encontrada foi de ( 347 ± 6 ) m/s, concordando com valores reportados na literatura. Dada a simplicidade e acurácia do experimento, este pode ser uma atividade viável para ser implementada tanto para laboratórios de ensino de física quanto para demonstrações em sala de aula.

Hiperprivatização do cuidado: projetos de cuidado das demências e seus efeitos
Authors: Engel Cíntia Liara
Published: November 2022

Resumo: Realizo uma comparação entre práticas cotidianas de cuidado das demências e políticas de cuidado voltadas ao envelhecimento com dependência no Brasil. A partir de uma etnografia realizada em casas, aprendo como cuidado agrega coletivos de pessoas, tecnologias e dinheiros. Por meio de uma análise documental das políticas de cuidado pós-democratização, narro projetos morais de cuidado e seus efeitos práticos - talvez o mais conhecido seja o que Guita Debert chamou de reprivatização do envelhecimento. Contudo, esse já não é mais o contexto atual; argumento que a perspectiva de cuidado da extrema-direita tem transformado esse cenário através de três movimentos articulados: restrição de serviços públicos; precarização do trabalho de cuidadoras e reforma das relações raciais; moralização do cuidado e reforma de gênero. Tal projeto é chamado, por fim, de hiperprivatização.
Objetificação da mulher: implicações de gênero na iminência da cirurgia bariátrica
Authors: Franco Suelen , Vieira Carla Maria , Oliveira Maria Rita Marques de
Published: November 2022

Resumo: A cirurgia bariátrica, realizada predominantemente em mulheres (80% no Brasil e 77% no contexto mundial), representa, além da prevenção de riscos aos agravos de saúde, uma promessa de bem-estar subjetivo. Neste trabalho, analisou-se, a partir da perspectiva de teorias feministas e psicodinâmicas, associadas à literatura da saúde, narrativas e expressões não verbais de um grupo de mulheres na iminência de tal cirurgia. Os resultados obtidos mostraram que aquele grupo de mulheres buscava a cirurgia como um dispositivo para alcançar a magreza como o padrão feminino idealizado socialmente. O corpo gordo foi reconhecido como uma condição não humana e a cirurgia simbolizada como a libertação dessa condição e o resgate da sexualidade. Concluiu-se, portanto, que as questões de gênero devem ser reconhecidas para apoiarem as equipes de saúde a fim de se mitigar expectativas irreais e melhorar o desfecho do tratamento da obesidade grave.

NEOLIBERALISM AND THE CONSTRUCTION OF THE CREATIVE SUBJECT
Authors: Ultramari Leonardo Roman , Nazario Luciano Da Costa , Pacce Benjamin Dias , Martins Eduardo Teixeira
Published: November 2022

Abstract: This article aims to problematize the position of the “creative subject” category in contemporary times, as well as its relations with the standards established by market practices. Two media discourses were analyzed, one uttered in the Saia Justa (GNT) TV show and the other in a commercial from the Shark Tank (ABC) TV show, both of them focused on creativity and entrepreneurship in the context of the COVID-19 pandemic. The analysis methodology was based on the French approach of Discourse Analysis. The results show a creative subject built from a neoliberal mechanism that (a) discursively silences the inequality-universality contradiction; (b) assigns value to creativity (and to the creative subject) based on the market logic (expenditure and competition); and (c) through the process of interpellation, induces the subject to identify him/herself with this neoliberal Other and regulate his/her creative volitions based on it.

Published: November 2022

Abstract This article analyzed a school's class assemblies from Edgar Morin's ethics perspective. How are class assemblies organized at Municipal Secondary Schools in Campinas/SP? How can they contribute to the understanding of ethics in the school environment? This research employed qualitative methods of interviews and observation. The results show that introductory activities to class assemblies - such as reading, music, and physical contact - develop self-knowledge, reduce hostilities and awaken recognition of the other. The study contributes to the reflection on conflict resolution in the school environment. It also contributes to understanding how conflict can be an opportunity for more mature social relations.
A consciência querológica na língua gestual portuguesa

Published: November 2022

Resumo A língua gestual portuguesa (LGP) é uma língua estruturada e natural, devendo, por isso, ser a escolhida no processo de ensino-aprendizagem das crianças surdas portuguesas. No entanto, há a necessidade de expandir o seu conhecimento, sobretudo sobre as etapas de desenvolvimento e aquisição, dando especial atenção à consciência querológica ‒ estudo da apropriação e o processo de construção desta competência pela criança/sujeito. Apesar da necessidade de maior aprofundamento dessa temática, as evidências apontam que o seu desenvolvimento assume um papel importante no processo de aquisição da linguagem. Neste sentido, atendendo à escassez de informação científica sobre a temática, este artigo, em formato de revisão de literatura, propõe-se a abordar a aquisição da LGP, através da descrição detalhada dos seus estágios, bem como dos diferentes contextos de aquisição. A consciência querológica é, então, abordada no âmbito da sua aquisição, parâmetros e lacunas ‒ conceituais e metodológicas ‒, inerentes ao seu estudo e avaliação.

Abstract We present the results of a survey conducted with students who are members of a student council at a public school in Santa Catarina. We seek to answer the question: what subject is the school producing in contemporary democracy? Based on post-structuralism, we aim to problematize the democratic practices of a student council. We used Deleuze, Guattari, and Foucault as our main theoretical framework. For data collection, we used a field diary composed of audios recorded at council meetings and transcriptions. Although the student council reflects on democratic management and establishes a space of multiple possibilities, it operates simultaneously as an extension of the curriculum by producing the docile, useful, and participative subject demanded by our time.

ABSTRACT One of the dilemmas that characterizes the end of active service of small hydroelectric plants (SHPs) is regarding the destination of the dams. This is the case of the Pandeiros SHP, located in the state of Minas Gerais, Brazil. Several alternatives are being considered to make its decommissioning feasible, such as opening the bottom discharge gate and removing the reservoir containment dike. However, in a review of recent research in the basin, more than 200 active gullies were found upstream of the dam, contributing to the silting up of the reservoir and of the Pantanal Mineiro, an extensive wetland downstream of the SHP that is vital to the biodiversity of the region. Following a worldwide movement to reuse such structures, periodic dredging of part of the sediment retained in the reservoir is proposed, converting it into a trap to reduce the silting of the wetland by the upstream sediment, in addition to the creation of a reserve volume of water needed for agriculture and human consumption.

Abstract One of the biggest issues in civil engineering is the poor performance of concrete repairs. In fact, in Europe only 50% of concrete structures restorations are estimated to be successful, even though rehabilitation costs account for about half of the yearly construction budgets. This research aims at investigating a potential green approach to the sustainability of rehabilitation solutions for infrastructures. Following a simplified analysis of C02 emissions, intervention costs, social aspects, structural performances and other variables considered relevant to the scope, possible rehabilitation techniques are compared and ranked. The following four different options have therefore been designed to be applied to an actual column of the Brabau Bridge in Sardinia (Italy): i. complete removal and replacement of the column, ii. replacement of the damaged longitudinal rebars by machined bars and ultra-high performance fibre-reinforced concrete (UHPFRC) strengthening, iii. longitudinal and transverse fiber reinforced polymers (FRP) wrapping, iv. concrete jacketing. A methodological and procedural strategy is established through multi-criteria analysis that will allow future developments to assess the whole Life Cycle Assessment of the maintenance work.

Abstract The environmental impact of reinforced concrete structures occurs during all phases of the building's life cycle, with emphasis on the stages of extraction and transport of raw materials and concrete production. An effective way to reduce the impact of these structures is to reduce the consumption of materials with the use of optimization techniques. The present study evaluates carbon dioxide emissions of concrete with two different compressive strengths for the region of Chapecó, SC. With these data, the optimization of structural elements was performed aiming to minimize their environmental impact. The carbonation of optimized elements was also evaluated. Among the results, it was observed that concretes with lower strength have better CO2 absorption rates (for the elements analyzed 20MPa concrete absorbed about 90% and 112% more CO2 than 35MPa concrete to columns and beams, respectively). In addition, it was observed that local factors can strongly influence the impacts, with the transport of materials reaching up to 6.4% of total emissions.

Abstract Concrete durability design has received increasing importance recently, with specifications moving from prescriptive to performance based. In performance-based approaches, it is essential to evaluate and calibrate service life models capable of reliably representing the phenomenon that triggers the degradation process. This paper aims to discuss the main concepts related to the probabilistic service life modeling of reinforced concrete structures under chloride environments, considering the application of different prediction models. Through numerical analysis, parametric differences among chloride penetration models are evidenced, and the results, their variability, and the admitted failure conditions are analyzed. An overview of the current scenario of the durability design of concrete structures is presented. Aspects associated with characteristic service life, the definitions of durability limit states, and their respective target failure probabilities are discussed.

abstract: The concern about the environment has been leading the construction industry to adopt more sustainable practices. The main environmental impact of concrete is related to CO2 emissions coming from cement, particularly from the cement content in concrete. For this reason, this research evaluates the performance of concretes with partial replacement of Portland cement by limestone filler and silica fume. These concretes were proportioned to improve particles’ packing and paste volume optimization. The compressive strength was determined to assess their mechanical performance. Their durability was investigated by capillary absorption and chloride penetration resistance. Results indicate that concretes showed a better efficiency in terms of binder intensity, with values close to the minimum found in literature (5 kg.m-3.MPa-1). It was also observed that even concretes with cement content lower than the minimum recommended by standards showed better performance than regular concretes regarding the chloride’s penetration.

Abstract Due to the scarcity of crystalline massifs in the north of Brazil, concrete producers have been using crushed stone and cement from suppliers located hundreds of kilometers away. In this case, CO2 emissions related to material transportation for concrete production may become significant. Thus, this study aims to analyze the influence of the transportation of the materials in CO2 emissions of ready-mix concrete production in Rio Branco (Acre). Concrete compositions were obtained from a local concrete producer. Brazilian methods of dosage were not applicable due to the high fineness of the regional sand available; the mix designs were adjusted empirically. Two types of cement (CP V-ARI and CP IV) were considered to create the studied scenarios. Transportation distances of the raw materials (cement and aggregates) ranged from 20 km (local sand supplier) to 3,592 km (cement supplier from Sete Lagoas, MG). CO2 emissions to produce concrete (fck of 25 MPa, cement consumption of 426 kg/m3) ranged from 208 kgCO2/m3 to 573 kgCO2/m3. Transportation was responsible for up to 20% of total emissions. The emissions in this study are considerably higher than the national data of concrete production available in the Construction Environmental Performance Information System (Sidac) due to the higher cement consumption and higher transportation distances. Although cement consumption in Acre represents less than 1% of Brazilian consumption, the results reveal the impact of transportation distances in CO2 emissions of concrete in cities that deal with local scarcity.

The effect of a non-axisymmetric inlet ports configuration of an internal-mixing twin-fluid atomizer on the spray characteristics is experimentally investigated. Inside the atomizer, two water jets are impinged on each other and are further disrupted by a central gas stream coming from the top. The operating conditions consider the variation of the gas mass flow rate at Reynolds and Weber numbers in the order of 104-105. Phase Doppler anemometry (PDA) measurements at four radial, four axial, and two perpendicular azimuthal positions are combined with a patternator device to obtain droplet size, axial velocity, and mass flux distributions. An approach for evaluating the overall spray asymmetry based on the mass flux distributions is proposed, which enabled the detection of slight asymmetries throughout the azimuthal direction, where especially differences in droplet sizes and velocities measured between the two azimuthal positions are observed. Higher Sauter mean diameters (SMDs) and lower velocities in regions of the spray with higher liquid mass flux are observed when compared to the azimuthal position perpendicular to it. In general, the liquid is considerably faster in the spray center than at the boundaries, where the fluctuating component of the velocity is higher due to the interaction of small droplets with the surrounding air. Overall, an increase in the gas flow rate reduces the droplet sizes and increases the velocity across the spray.
