Cotton leaf curl Multan betasatellite impaired ToLCNDV ability to maintain cotton leaf curl Multan alphasatellite
Authors: Iqbal Z. , Shafiq M. , Briddon R. W.
Published: July 2022

Abstract Alphasatellites (family Alphasatellitidae) are circular, single-stranded (ss) DNA molecules of ~1350 nucleotide in size that have been characterized in both the Old and New Worlds. Alphasatellites have inherent ability to self-replicate, which is accomplished by a single protein, replication-associated protein (Rep). Although the precise function of alphasatellite is yet unknown, and these consider dispensable for infectivity, however, their Rep protein functions as a suppressor of host defence. While alphasatellites are most frequently associated with begomoviruses, particularly with monopartite than bipartite begomoviruses, they have recently been found associated with mastreviruses. The in planta maintenance of alphasatellites by helper geminivirus is still an enigma, with no available study on the topic. This study aimed to investigate whether a widely distributed bipartite begomovirus, tomato leaf curl New Delhi virus (ToLCNDV), can maintain cotton leaf curl Multan alphasatellite (CLCuMuA) in the presence or absence of cotton leaf curl Multan betasatellite (CLCuMuB). The findings of this study demonstrated that ToLCNDV or its DNA A could maintain CLCuMuA in Nicotiana benthamiana plants. However, the presence of CLCuMuB interferes with the maintenance of CLCuMuA, and mutations in the CP of ToLCNDV further reduces it. Our study highlighted that the maintenance of alphasatellites is impaired in the presence of a betasatellite by ToLCNDV. Further investigation is needed to unravel all the interactions between a helper virus and an alphasatellites.

Abstract Foot-and-mouth disease is responsible for severe economic losses to the livestock industry of Pakistan. This study aimed to use Swiss albino mice as a cost-effective experimental animal model to study different immunological and histopathological aspects of FMDV instead of natural targeted species like cattle. After isolation of field isolates FMDV on BHK-21 cell line, biological titer of the virus and mice infectious dose50 was calculated. Virus was injected in 45 Swiss albino mice (group A) through intraperitoneal route. The gross, histopathological and immunopathological lesions in heart, trachea and lungs were recorded at different day’s intervals. Histopathologically, the heart showed congestion, hemorrhages and necrosis of cardiac muscles. Trachea showed deciliated epithelium and lungs showed hemorrhages, bronchial edema and alveolar emphysema. Immunohistochemical studies revealed the presence of virus in cardiac muscles, tracheal and bronchial epithelium and alveolar lumen. The findings evoked a thought that laboratory animals could be an alternative to large animals to meet budget limitations for further research on foot-and-mouth-disease.

Published: July 2022

ABSTRACT Objective To describe the development and update of an instrument for food categorisation according to the extension and purpose of industrial processing, and to test its practical application. Methods After updating the instrument based on a recent publication on the NOVA classification, it was applied by five researchers to a database of 108 food items. These items are part of a database of foods announced in the health-related sections of supermarket promotional circulars. The Cohen’s weighted kappa coefficient was calculated to determine intra-rater agreement; Fleiss’ kappa and Kendall’s coefficient were applied to determine inter-rater agreement. Results In the updated version, two classes of additives and eight substances considered by the most recent publication as specific to ultra-processed foods were added. The intra-rater agreement was 100% (p<0.001), indicating an “almost perfect” agreement; Fleiss’ agreement among all raters ranged from 74% to 97% (p<0.001), which represents an agreement that ranged from “strong” to “almost perfect”; Kendall’s W was higher than 0.93 (p<0.001) among all raters. Conclusion The updated instrument showed high agreement and proved to be a methodologically sound and applicable tool for the purpose of classifying foods by the extension and purpose of industrial processing.
Consumer grief: understanding how consumers deal with the loss of extraordinary experiences
Authors: Scussel Fernanda , Suarez Maribel Carvalho
Published: July 2022

Abstract Despite the interest in the role of consumption in the bereavement process, the concept of consumer grief and the process consumers experience when grieving remain undertheorized. This article aims to conceptualize consumer grief considering the disruption brought by the COVID-19 pandemic and the need to understand how consumers respond to this scenario, understanding the mechanisms consumers create to deal with loss. In view of the importance of extraordinary experiences due to their embodied, social, and transformational power, in this netnographic study, we explore marathon runners’ loss of an extraordinary experience. Consumers deal with the loss of an experience through a process composed of five mechanisms mediated by social media, which enable consumers to reverse, reframe, and reestablish the experience. The mechanisms of refutation, despair, abstention-compensation, transgression, and acceptance show how consumers behave in different moments of grief, allowing them to build their trajectories in the grieving process, individually and collectively. As a contribution, we expand the literature on consumer grief by focusing on the specific concept of consumer grief, explaining the processes consumers go through when they deal with the loss of an experience. Additionally, we present a collective perspective on the grieving process, shifting the analysis of the grief of an individual or a family unit to the socialization of grief.
COVID-19 as a gender market issue: is it a call for action against vulnerability?
Authors: LUNA CAMILLA PINTO , SILVA ROSANA OLIVEIRA DA , BARROS DENISE FRANCA
Published: July 2022

Abstract Gender-based domestic violence has increased considerably in Brazil during the COVID-19 pandemic. This alarming situation has affected the market and has inspired individuals and organizations to create initiatives to tackle the issue. This article seeks to understand how the links between market practices prompt discussions on social issues such as women’s vulnerability in the face of domestic violence. The methodological path was built around an initiative by Magazine Luiza (a major Brazilian retailer): the panic button in the Magalu app. A corpus was formed, gathering news about the initiative and analyzed afterward. Although Magalu’s market practices can be seen as influential in the fight against gender violence, there is imminent danger of relegating the defense of women to the market sphere, whereas in contrast, the creation of resilience is, without a doubt, the result of joint action by society as a whole.
A questão dos modelos no ensino de Mecânica Quântica: a equação de Schrödinger para partículas de spin semi-inteiro
Authors: Olavo L.S.F. , Ferreira Marcello , Amorim Ronni G. G. de
Published: July 2022

Neste artigo, discutimos noções de modelos utilizados nas ciências e, em particular, no âmbito da Mecânica Quântica, apresentando um modelo físico para partículas de spin semi-inteiro. Ele é baseado na quantização de uma representação do sistema realizada no espaço de fase, fornecendo a representação de Schrödinger que descreve partículas de spin semi-inteiro. A partir das soluções da equação, derivamos as representações usuais dadas na literatura em termos de matrizes. A vantagem da arquitetura aqui apresentada é a discussão do problema do spin a partir da interpretação de Schrödinger para a Mecânica Quântica. Discutimos, assim, a possibilidade do spin ser visto como uma variável dinâmica, substituindo a sua corriqueira interpretação como propriedade intrínseca da partícula. Por fim, ficaram aduzidas possibilidades de incursão epistemológica e de transposição didática, além de assinaladas as limitações curriculares mais típicas.
Portfolio theory approach to plan areas for growing cotton, soybean, and corn in Mato Grosso, Brazil
Authors: Lima Fábio Francisco de , Alves Lucilio Rogerio Aparecido
Published: July 2022

Abstract: This study aims to describe how cotton farms in the state of Mato Grosso in Brazil are configured by building a model that optimizes income and risk for a combination of crops (cotton [first and second crop], soybean, and corn second crop). Two regions were defined: North and East Central Aggregate. The first region comprises the production of soybean in the summer and cotton and corn in the second harvest, while the second is restricted to the cultivation of cotton and soybean in the summer and corn in the second harvest. An optimization model was used to build a production efficiente frontier of crop combinations by analyzing the return-risk ratio. The model shows that the use of soybean crops in the summer season provides greater gains in profitability. Revenue is maximized in the area by an increase in the cotton crop during the first harvest; however, this exposes the farm to greater production risks. The use of second crops helps mitigate this production risk for farms.
Food policies and sectorial referentials in the Brazilian trajectory
Authors: Grisa Catia , Porto Silvio Isoppo
Published: July 2022

Abstract: The paper analyses the referentials that has guided the design and implementation of food policies in Brazil. Based on documentary research and literature review, we identified six phases in Brazilian food policies: i) 1600-1930, with the presence of a referential of inaction; ii) from 1930 to 1960, with a referential oriented towards rational nutritional; iii) 1970 to 1980, guided by productivist interpretations and supply actions; iv) the 1990s, with a referential of commercial efficiency and social assistance focus; v) 2000 to 2015, with a referential of conflicting coexistence between productivism and food and nutrition security (FNS); vi) from 2014, under a dismantling sectorial referential. Over time, the most meaningful and constant actions were those that sought to change the dynamics of agricultural production, which were biased towards commodities expansion. The actions that sought to promote food accessibility, healthy diet, dialogue between family farming and FNS, agroecology and the valorization of local territories and food were fragile and unstable, sensitive to political and economic changes.

Published: July 2022

ABSTRACT Peanut crops are of great economic interest because their seeds are used as an important source of vegetable protein and edible oil. The objective of this study was to evaluate the physiological indices and growth of peanut crops subjected to saline and water stress. The experiment was conducted in Auroras, Redenção, Ceará, Brazil using a completely randomized split plot statistical design. The plots were composed of irrigation water treatments with varying levels of electrical conductivity - ECw (1.0, 2.0, 3.0, 4.0 and 5.0 dS m-1), while the subplots were formed by the water regimes of 50% and 100% crop evapotranspiration. Plant height, leaf number, shoot dry matter, relative chlorophyll level, transpiration, and leaf temperature were affected by salt stress. The water regime of 100% ETc provided better performance for the variables stem diameter, leaf number, and shoot dry mass of peanuts.

Authors: Hao Baoer , Tong Xin , Chen Zhi , Liu Haiyang
Published: July 2022

ABSTRACT To construct a coupled simulation model of soil wind erosion and two-phase flow in arid and semiarid regions, the proper contact parameters of the soil discrete element simulation model are obtained based on the angle of repose (AoR) calibration test. The coupled simulation model is established by combining computational fluid dynamics. The response value of the wind speed of sand initiation is used to verify the model’s accuracy. Due to the characteristics of arid and semiarid soils, this paper uses the Hertz-Mindlin with JKR contact model in EDEM software to calibrate the soil parameters based on soil physical tests and designs the Plackett-Burman, steepest climb, and Box-Behnken tests according to Design-Expert software to obtain the soil AoR second-order regression. With the AoR of 33.52° as the target, the best combination of parameters is obtained: soil-soil collision recovery of 0.64, soil-steel static friction coefficient of 0.31, JKR surface energy of 3.302 J m-2. Finally, by using calibrated parameters and the threshold wind velocity as the response value, the wind-sand air-solid two-phase flow test is conducted in ANSYS Fluent and EDEM, with the relative error between the starting wind speed recorded by the high-speed camera in the wind tunnel test and the threshold wind velocity shown in the simulation model calculated to be 8.7%, and the calibrated soil parameters met the requirements of the coupled simulation.
Simulating sugarcane yield response to ETc replacements and green cane trash blanket maintenance in Brazil
Authors: Gonçalves Ivo Z. , Costa Leandro G. da , Marin Fábio R.
Published: July 2022

ABSTRACT Determining the proper crop water requirement associated with the optimum amount of green cane trash blanket (GCTB) on the soil is one of the most discussed issues for sugarcane growers. In this context, this research aimed to evaluate the effects of different amounts of GCTB and ETc replacement scenarios on sugarcane yields across key producing regions in Brazil using the agricultural production systems simulator (APSIM). The sugarcane APSIM (APSIM-Sugar) was parameterized and validated for sugarcane in Brazil, compared to both 100% GCTB cover and bare soil, both fully irrigated. After validation through field data, the APSIM-Sugar model was used to simulate 25 different scenarios with varying GCTB amounts and irrigation demands in 12 regions of Brazil for a 30-year period to estimate stalk yield. Overall, modeled and field data agreed very well regarding soil moisture and biometric and physiological variables, achieving strong modeling efficiency. For most producing regions of Brazil, interaction between the factors did not increase stalk yield significantly, and up to 50% of ETc replacement resulted in the highest increases in stalk yield, with the greatest improvement between 0-25%, producing an average increase of 30 Mg ha-1 per year. The recommended amount of GCTB is at least 5.50 Mg ha-1, taking into account soil health and the need for biofuel generation.

ABSTRACT The objective of this work was to select a cotton line tolerant to water stress, based on yield and fiber quality characteristics. A total of nine cotton genotypes were evaluated (six breeding lines and three commercial cultivars) in two field experiments conducted in Quixeramobim - CE without water supplementation in 2018 and 2019, respectively. Traits related to cotton lint yield and intrinsic fiber quality were measured. Data were submitted to individual and joint analysis of variance, and selection by the selection index. The genetic variability among the materials demonstrates the possibility of significant gains in the cotton selection process. The genotypes CNPA 2013 - 2235 RF FL, CNPA 2013 - 2064 RF FL and CNPA 2012 - 160 RF FL, as well as the cultivar FM 944 GL, had higher production and better fiber quality under rainfed conditions.

Abstract Introduction The elderly are among those most affected by Covid-19, and among them are people with Parkinson's disease. Social distancing, due to the coronavirus, has led to new strategies and tools for health monitoring. Objective To describe the oral health conditions, using telemonitoring, of people with Parkinson's disease during the Covid-19 pandemic. Material and method This is an analytical, quantitative, cross-sectional study. The tool used was the video call. The telephone contacts (n=154) were obtained from lists of patients in the Pro-Parkinson Extension Program at the Federal University of Pernambuco. A semi-structured questionnaire was used to gather sociodemographic data and daily oral hygiene practices for teeth and dentures, and whether or not the participant needed dental treatment, during the Covid-19 pandemic. Result The final sample consisted of 64 Parkinsonian patients. Regarding oral health care, the frequency of hygiene in this period was three times a day among 48.44% of participants, with toothbrush and toothpaste being the items most used for this task. More than half of the sample used dental prostheses. The most common oral health problems during this isolation period were pain, mouth sores and the need for tooth extraction. Conclusion Telemonitoring was essential because it was noted that these patients were deficient in their knowledge of basic hygiene practices and in information on oral health, as well as in the care of dental prostheses.

Published: July 2022

ABSTRACT Objective: Evaluate the biomechanical behavior of the influence of different internal angles of conical prosthetic connections in fixed partial prostheses of three elements, through the tridimensional finite element method. Methods: Two different models of segment of the posterior portion of the mandible, with two implants with conical connections at angulations of 11.5 and 16 degrees. Afterwards, and occlusal load of 180N was used, and divided into 2 points of application on the premolar, and 400N divided into 5 points of application on the molar. Data were acquired as the tensile, compressive and shear stresses on cortical and medullary bone, and von Mises stresses on implants and prosthetic components of two implants in both in three-unit fixed partial prosthesis. In the quantitative analysis, both in cortical and medullary bone, the tension peaks in tensile, compression, and shear forces were higher for the CM16 group. Results: When analyzing qualitatively, the cortical and medullary bones presented a greater stress around the implant platform with a higher incidence in the implant in the molar region. In the von Misses analysis in both groups, the tensions were concentrated in the cervical region of the implants, in the first threads, in the premolar and molar regions. Regarding prosthetic pillars, the stress concentration was located in the region of contact with the implant. Conclusion: The increased angulation of conicity of the internal conical connections represents a determinant factor to increase in stress concentration in the implants, prosthetic components and adjacent structures, such as the cortical and medullary bone.

Published: July 2022

Resumo Introdução: Glomerulonefrite membranoproliferativa (GNMP) é uma doença glomerular rara com prognóstico variável. Recentemente, foi proposta uma nova classificação baseada na presença ou ausência de imunoglobulinas e depósitos de complemento na microscopia de imunofluorescência (IF) da biópsia renal. Os objetivos do estudo foram determinar e comparar as características clínicas, laboratoriais e histopatológicas daqueles com GNMP primária ou secundária, reclassificar as primárias com base em achados da IF e avaliar os desfechos renais. Métodos: Este foi um estudo de coorte observacional retrospectivo realizado em centro único (UNIFESP), com base nos dados coletados de prontuários de pacientes acompanhados de 1996 a 2019. Resultados: Dos 53 casos de GNMP, 36 (67,9%) foram classificados como GNMP primária e 17 (32,1%) como GNMP secundária. A maioria dos pacientes era hipertensa (84,9%) e apresentava edema (88,7%) e anemia (84,9%); 33 (91,7%) pacientes classificados como GNMP primária foram reclassificados como mediados por imunocomplexo e 3 (8,3%) como mediados por complemento. O grupo de GNMP secundária apresentou mais frequentemente hematúria (p <0,001) e maior prevalência de depósitos de IgG (p = 0,02) e C1q (p = 0,003). Com relação ao desfecho, 39% dos pacientes alcançaram remissão parcial ou completa. Albumina sérica inicial mais baixa e proteinúria de 24 horas inicial mais elevada foram fatores associados a pior prognóstico renal. Conclusões: De acordo com a nova classificação histológica, a grande maioria dos casos de GNMP foram classificados como sendo mediados por imunocomplexos. Houve poucas diferenças entre GNMP primária e secundária em relação às suas características clínicas e laboratoriais.

ABSTRACT The aim of this study was to produce exploratory multimodal analysis on joint attention. We used the ELAN tool: software with resources for temporal and special synchronization for verbal and non-verbal modalities that facilitate the visualization and annotation of interactional contexts. Excerpts of ten minutes of speech and language pathology evaluation of the child with suspected ASD and of another child with typical development matched by age group and gender, were analyzed and transcribed. Spontaneous occurrences of the child's gaze were investigated: a) Towards the interlocutor's eyes. b) Towards toys or play. c) Towards the interlocutor's eyes and toys (Joint Attention). The occurrences of look direction differed between children in a quantitative and qualitative way. The child with suspected ASD did not produce an episode of joint attention, nor did he direct his gaze to the interlocutor. There were 56 occurrences of gazing towards the toys. The typical child produced 18 occurrences of joint attention, and whenever he directed his eyes to the interlocutor's eyes, he did so with the intention of sharing the toy or play. We also observed 37 occurrences of gazing towards the toy or play. From the exploratory analysis produced by ELAN tool, it was possible to observe that there were differences in the number of occurrences and look direction between the evaluated children and to verify that the joint attention was absent in the child with ASD risk.

RESUMO O presente artigo analisa novas demandas conservadoras articuladas nas políticas educacionais para a educação básica, focando no modo como essa articulação vem excluindo a atividade política democrática por meio de um discurso autoritário. Essa análise toma como referência a proposta do Programa Nacional das Escolas Cívico-Militares, operando com a estratégia teórico-discursiva proposta por Laclau e Mouffe. São destacados na análise a lógica de gestão educacional defendida nesse Programa, como essa lógica é constituída e as razões pelas quais isso se dá. O artigo considera limitados os discursos firmados na normatividade e na afirmação de totalidades essencialistas para a contestação dessa nova dinâmica social suturada e com diferentes identidades políticas emergentes.
Educate to humanize of Max Scheler and the post-modernity of Zygmunt Bauman
Authors: Ferreira Virgínia da Silva , Werneck Vera Rudge
Published: July 2022

ABSTRACT Education has always been and remains the object of interest, studies, investigations, analyses and reflections by various actors of society, from the sphere of public policies to various areas of knowledge, specially the human and social sciences. Understanding the human being and all phenomena concerning it, specifically education, as inherent in life in society and politics, the transformation of education is linked to, perhaps even subordinated to, the political, social and economic changes that take place from time to time, from society to society. This article aims to discuss if education as proposed by M. Scheler has a place in the postmodernity of Z. Bauman, a time in which volatility, disposability, immediacy and consumerism reign sovereign, in which things only have value for their utility.
Formação humana na precariedade: fazer sentido em comum

Published: July 2022

RESUMO “Não há mundo comum,” afirmava Bruno Latour, “jamais houve.” Como então nos habituamos a imaginar a existência de um consenso que, por trás dos desacordos e dos conflitos, cimentava nossa existência comum? E se os diferendos, longe de se constituírem, como quis a Modernidade, em fenômenos passageiros e superficiais, atribuídos a erros pedagógicos e de comunicação, fossem a vida própria do pluriverso que habitamos? Então, como evitar pensar que a própria ideia de uma verdade inabalável, unicamente acessível pelos saberes especializados, por uma ciência acima dos valores e apartada dos interesses humanos, tenha sido uma das primeiras fake news da Modernidade? O mundo comum “ainda está por ser composto,” insiste Latour. Mas, como fazê-lo? Eis o que pretende interrogar o presente texto, com o apoio nas reflexões que desenvolve Isabelle Stengers.

ABSTRACT “There is no common world,” stated Bruno Latour in a Manifesto, “there never was.” How then do we get used to imagining the existence of a consensus that, overcoming disagreements and conflicts, cemented our common existence? And if the disputes, far from being passing and superficial phenomena to be attributed to pedagogical and communication errors, as Modernity supposed, were the very life of the pluriverse we inhabit? Then, how to avoid thinking that the mere idea of an unshakable truth, only accessible by specialized knowledge, by a science above values and apart from human interests, was one of the first fake news of Modernity? The common world “is yet to be composed,” insists Latour. But, how to do it? This is what the present text intends to discuss, with the support of Isabelle Stengers’ works.

RESUMO A atual perda global de biodiversidade tem ameaçado a provisão de água potável para abastecimento público, sobretudo por causa da perda de florestas nativas. Assim, uma compreensão dos impactos da redução de cobertura vegetal em paisagens degradadas por atividades humanas é uma ação importante para garantir segurança hídrica. O presente estudo avaliou a relação entre a qualidade da água e os custos de tratamento e a intensificação do uso do solo de seis pontos de captação de água para abastecimento público no sul da Bahia, Brasil. Consideraram-se seis escalas espaciais, o ponto de captação e seu entorno (local), quatro faixas de zona ripária (30, 50, 100 e 200 m) e a microbacia hidrográfica. Uma seleção de modelos foi conduzida para determinar em qual escala a intensificação da paisagem melhor explana os custos de tratamento e a qualidade de água. Usando uma análise de componentes principais em cada escala espacial, um gradiente de substituição de florestas por outros usos não florestais (PC1) foi gerado e usado como uma variável explanatória. Como resultado, a intensificação do uso do solo na zona ripária de 100 m foi o melhor modelo para ambas as variáveis resposta. Portanto, o estudo sugere que ações de conservação e restauração dos recursos hídricos da área de estudo devem considerar uma zona ripária de pelo menos 100 m de cada lado dos corpos d’água para reduzir os custos de tratamento em curto e médio prazo. Adicionalmente, a recuperação da cobertura florestal é uma ação crucial para manejar as zonas ripárias e bacias hidrográficas.

Abstract The objective of this work was to evaluate the induction of indirect organogenesis by concentrations of dichlorophenoxyacetic acid (2,4-D) and thidiazuron (TDZ) in pitaya (Hylocereus undatus) explants, using scanning electron microscopy and the flow cytometry technique. The treatments consisted of the concentrations of 0, 2.0, and 4.0 mg L-1 2,4-D and TDZ and of the combinations of these regulators. Percentages of callus coverage at 45 and 60 days were evaluated. The explants subjected to the treatments were analized by flow cytometry and scanning electron microscopy. All treatments induced endoreduplication, and there was no somaclonal variation. Under the combination of 2.0 mg L-1 TDZ and 4.0 mg L-1 2,4-D, calluses were formed in 95% of the explants, but were smaller than those produced with 2,4-D separately. The concentration of 2.0 mg L-1 TDZ induces the indirect organogenesis in pitaya explants, confirmed by the presence of conducting vessels through scanning electron microscopy.
Batalhadores culturais: trajetórias de mobilidade ascendente nos meios populares
Authors: Alves Ana Rodrigues Cavalcanti
Published: July 2022

Resumo Este artigo visa discutir trajetórias de mobilidade ascendente entre as classes populares brasileiras por meio da aquisição de capital escolar e inserção no ensino superior nas últimas décadas. A investigação se ancora em uma abordagem teórico-metodológica disposicionalista, que busca analisar as condições objetivas e subjetivas que permitiram o rompimento das fronteiras de classe e a ascensão social por meio do ingresso em um curso de nível superior. Para tanto, foi realizada uma pesquisa qualitativa envolvendo entrevistas em profundidade com membros dessa fração de classe, residentes na região metropolitana de Recife (PE), entre os anos de 2015 e 2016 (denominados neste trabalho como batalhadores culturais, dada sua mobilidade ascendente mediante a incorporação de um montante de capital cultural). A pesquisa buscou reconstruir a trajetória desses membros, bem como as principais disposições e valores constitutivos de seu ethos de classe responsáveis pelo seu processo de mobilidade ascendente via escolarização. A análise permitiu identificar um conjunto de disposições incorporadas no decorrer da trajetória desses indivíduos que favoreceu a aquisição de capital escolar e outras formas de capital cultural, projetando-os ao topo dessa fração de classe. Por outro lado, é possível observar as tensões e conflitos associados às suas tentativas de “subir na vida”, além de um ajuste das expectativas geradas pela aquisição de um diploma de ensino superior à realidade, diante das oportunidades encontradas pelos(as) estudantes egressos(as).

ABSTRACT Introduction: Spinopelvic parameters related to sagittal balance have become increasinglyimportantamong spine surgeons due to their correlation with patient satisfaction rates. Objective: The goal of this study was to evaluate changes in spinal sagittal balance after lumbar spine surgery using PLIF, the posterior lumbar interbody fusion technique. Methods: The sample consisted of adult patients with degenerative spinal disease submitted to posterior lumbar arthrodesis. Patients between 18 and 70 years of agewho underwent surgeryfrom 2015 to 2017 were included in the study and divided into short (1 level) and long arthrodesis (2 to 4 levels) groups. Radiographic analysis of the spinopelvic parameters, measured before and after lumbar arthrodesis, was conducted using the SURGIMAP software. Then we evaluated the variation between pre- and postoperative measurements and performed correlation and linear regression analyses between the parameters. Results: The sample was composed of 80 patients (48 men). The mean age was lower in the short arthrodesis group than in the long arthrodesis group (52.67 ± 9.66 years versus 59.37 ± 9.30 years, respectively; p<0.0025). Significant variations in lumbar lordosis, pelvic tilt, sagittal vertical axis, T1 pelvic angle, and pelvic incidence minus lumbar lordosis were found in both short and long arthrodesis groups. The variation was significantly larger in the long than in the short arthrodesis group. Conclusion: In adult degenerative spine disease, short and long arthrodesis of the lumbar spine by PLIF allows correction of the spinopelvic parameters.

ABSTRACT Objective: Rate and compare radiographic measurements of thoracic kyphosis and lumbar lordosis using anatomical and dynamic parameters. Methods: Measurements were performed on lateral radiographs of 10 adults of both sexes without spinal disease or deformity. Thoracic kyphosis and lumbar lordosis were measured using anatomical parameters (T1-T12, T4-T12, T5-T12 and L1-S1) or dynamic parameters (cervicothoracic or thoracolumbar inflection point). Results: Thoracic kyphosis and lumbar lordosis were different in 30% of subjects. Differences in thoracic kyphosis values were observed according to the anatomical reference used for measurement. Lumbar lordosis wasn`t statistical difference considering the anatomical or dynamic reference, but in 30% of the individuals the inflection point was different from the anatomical reference. Conclusions: Thoracic kyphosis and lumbar lordosis values differ according to anatomical and dynamic references. The reference used must be considered in the measurement and interpretation of values. Level of evidence IV; Case series.

Alkali-activated binders are emerging sustainable binders in the construction sector due to their higher strength and superior resistance against aggressive environments than those of cement concrete. Steatite powder is obtained as a by-product of soapstone processing and disposed of as waste in large quantities. Studies on the reuse of steatite powder in alkali-activated concrete are few. Hence, the current research focuses on the influence of ultra-fine steatite powder on the mechanical as well as durability properties of slag- and fly-ash-based alkali-activated concrete. Six replacement levels (10, 20, 30, 40, 50 and 60%) of slag and fly ash with steatite powder were adopted and activated using a sodium-based activator. Heat curing and ambient curing were performed for fly ash–steatite concrete and slag–steatite concrete, respectively. From the test results, 30% steatite powder is the optimum for slag- and fly-ash-based alkali-activated concretes. Less water absorption and higher resistance against acid exposure are observed for steatite-based alkali-activated concrete specimens.

This study examined the effect of the unit weight and compressive strength of concrete on the punching shear capacity of flat slabs without shear reinforcements. The slabs were prepared using all-lightweight aggregate concrete (ALWAC), sand-lightweight aggregate concrete (SLWAC), and normal-weight concrete (NWC) at the different compressive strengths of concrete of 24 and 45 MPa. Based on the upper-bound theorem of concrete plasticity, the failure surface generatrix is generalized to account for the increased horizontal extension with a decrease in the unit weight of concrete. Thus, the punching shear capacity of concrete flat slabs is mathematically driven considering the reduced effective strengths of LWAC under tension and compression. Test results showed that the radius of the punching shear tended to increase with a decrease in the unit weight of concrete. This yielded a lower normalized punching shear capacity observed for ALWAC or SLWAC flat slabs than NWC flat slabs. The proposed model accurately estimated the punching shear capacity, indicating that the mean and standard deviation of the ratios between the experiments and predictions were 1.10 and 0.05, respectively. This indicated that the proposed model reasonably reflects the reduced aggregate interlock action of lightweight aggregates.
