Authors: Lima Giovana Felício , Machado Mick Lennon , Martins Milena Corrêa , Pinto Murilo Lyra , Gabriel Cristine Garcia
Published: September 2023

ABSTRACT Objective: The research was carried out with the objective of evaluating the conditions for the promotion of food and nutrition security in three capitals of the southern region of Brazil. Methods: This is an evaluative research, which used an analysis and judgment matrix composed of 7 dimensions, 11 sub-dimensions, 27 indicators and 56 measures, which classified each of the elements of the matrix as excellent, good, regular or poor for the promotion of food and nutrition security in the three capitals. Data collection took place in public and freely accessible information systems. Results: The three capitals were evaluated as poor in their conditions for promoting food and nutrition security. Florianópolis and Porto Alegre presented less favorable conditions compared to Curitiba. Aspects related to universal access to adequate food and water, agroecological production systems and sustainable food supply, and traditional peoples and communities stood out negatively in the three capitals. Conclusion: Although the evaluated capitals present good socioeconomic indicators, the conditions for promoting food and nutrition security are still fragile, which is reflected in the inability to overcome hunger and food insecurity in the southern region of Brazil. The results indicate the need to qualify territorial strategies for food and nutrition security, considering different contexts, as a condition for guaranteeing the realization of the right to food with equity and priority for families and peoples in situations of social vulnerability.

Published: September 2023

ABSTRACT In Brazil, the estimated number of new cancer cases between 2020 and 2022 is 625 thousand, and the most prevalent carcinomas are primarily skin (non-melanoma), followed by those of the breast, prostate, colon, and rectum. Although breast carcinoma still has a high mortality rate, it has a good prognosis due to the increase in early diagnosis and the evolution of anticancer treatments. The proposed treatment can be isolated or associated with resective surgery, radiotherapy, chemotherapy, and/or hormone replacement. Chemotherapy generates extensive immunosuppression and affects both healthy and altered cells, and the cytotoxicity of the treatment is an important effect that can cause lesions on the oral mucosa. Severity is related to the type of chemotherapeutic agent, treatment time, the dose used, and the individual’s age. Additionally, chemotherapy treatment can exacerbate preexisting conditions in the individual and cause greater discomfort during treatment. Therefore, monitoring oral health before, during, and after anticancer therapy is essential. The objective of this work is to report a clinical case of dental emergency in a patient after the first cycle of doxorubicin- cyclophosphamide-paclitaxel (ACTdd) to treat breast cancer.

ABSTRACT Objective: To develop and validate a prototype of a mobile application shift handover between nurses in the emergency room using a severity scale. Method: This is a technological tool carried out at the Universidade Estadual de Maringá using design thinking, divided into four phases: discovering, defining, developing, and delivering. To structure the information, a checklist was used based on the Situation Background Assessment Recommendation, and to categorize patients in terms of severity, the National Early Warning Score was used. The validation of the sample was carried out by 10 nurses, specialized in the field of urgency and emergency, using the System Usability Scale questionnaire to assess usability. The content validity coefficient was used for analysis. Results: The application scored 75.75 in usability and had a content validity coefficient of 0.8. Conclusion: The prototype obtained an excellent evaluation of usability and agreement between evaluators. Future studies are needed for implementation in practice, evaluating the practicality, applicability, efficiency and time savings in shift information transfer.
BETWEEN NORMS AND ROUTINES OF ORGANIC CHEMISTRY: THE WORK WITH THE DOMAINS OF SCIENTIFIC KNOWLEDGE
Authors: Silva Fernando César , Sasseron Lúcia Helena
Published: September 2023

ABSTRACT: We assume that the approximation of norms and routines characteristic of scientific activity can be an element that promotes science learning. Thus, we aim to answer the research question: “In Organic Chemistry classes for Higher Education students, which domains of scientific knowledge are mobilized by the professor?”. Therefore, Organic Chemistry classes in a teacher training program in Chemistry were recorded in audio and video. The data produced for this research come from the transcription of these recordings and were analyzed qualitatively in order to identify mobilization of the domains of scientific knowledge by the professor. The results indicated that the conceptual and material domains appear frequently, and the epistemic rarely. The social domain, on the other hand, appears linked to the use of representations. When interacting with these domains, the professor relates the experimental material to the use of representations. As implications of this research, we defend the idea of an epistemic object to approach visual representations and characterize the material domain.

Published: September 2023

ABSTRACT One of the challenges of the energy sector is the identification of renewable resources with less impact on the environment and that are economically viable. This study aimed to estimate the genetic diversity of eleven full-sib families of elephant grass, using quantitative traits associated with bioenergy production. The trial followed a randomized blocks design, with four replications and each plot (family) consisting of five plants, totaling 220 genotypes. Five quantitative traits were measured: dry matter yield, dry matter percentage, plant height, stem diameter and number of tillers. The genetic diversity was estimated using multivariate methods (principal component analysis and hierarchical clustering). The analysis revealed a significant genetic diversity among the full-sib of elephant grass, with a greater variability observed for dry matter yield and number of tillers. The families 1, 2, 5, 7 and 8 exhibited superior genotypes for bioenergy production-related traits. The grouping analysis generated twenty clusters, enabling the differentiation of genotypes. Eight clusters comprised genotypes with a high dry matter yield and plant height, simultaneously, surpassing the overall mean for number of tillers.
UMA SOCIEDADE DE CAPELAS: OS PATRIMÔNIOS RELIGIOSOS NA FORMAÇÃO DO TERRITÓRIO DA VILA DE CASA BRANCA NA PROVÍNCIA DE SÃO PAULO, SÉCULO XIX;
Authors: Ferreira Rafael Augusto Silva , Pereira Renata Baesso
Published: September 2023

Resumo No termo da Vila de Casa Branca, na Província de São Paulo, em meados do século XIX, doações de patrimônios de capelas permitiram a gênese de povoações, posteriormente elevadas a capelas curadas e freguesias. O artigo demonstra a formação da rede urbana, analisando a relação entre o poder secular e a Igreja Católica na ocupação territorial, um processo que envolveu as paróquias da região e instâncias do poder civil e judiciário no reconhecimento e posse dos patrimônios de capelas. As fontes primárias analisadas são a documentação textual civil e eclesiástica da região, espacializada em um SIG histórico que reconstitui o território da aplicação da capela do Rio do Peixe e sua população livre e cativa. A elaboração de um SIG histórico permite analisar a relação entre as fazendas, a rede de caminhos, as capelas e os patrimônios existentes, revelando hierarquias sociais e redes de clientelismo em torno das capelas curadas, apontando para sua relevância no cotidiano dos coevos do século XIX.
Crescer consumindo na periferia: um olhar sobre o consumo em No país da infância, de Cris Lira
Authors: Bezerra Lígia
Published: September 2023

Resumo Neste artigo, que tem como foco uma análise da representação do consumo na periferia no livro de contos No país da infância (2019), da escritora brasileira Cris Lira, argumento que, por meio de uma perspectiva cotidiana, no sentido lefebvriano, que vê o cotidiano como algo “humilde e sólido”, as histórias de Lira refletem e ao mesmo tempo constroem experiências e narrativas afetivas e críticas do que significa/significou crescer na periferia brasileira nos anos 1980 e 90 diante das pressões da sociedade de consumo. Demonstro que Lira (2019), ao imaginar os usos de várias mercadorias, identifica o que Hans Ulrich Gumbrecht (2006) chama de “crises”, ou seja, pequenas interrupções do cotidiano que a experiência estética com bens de consumo pode produzir. Nessa perspectiva, No país da infância tece uma crítica esperançosa do cotidiano da sociedade de consumo, alinhando-se a autores como Marcus Vinícius Faustini (2009) em sua representação da periferia, conforme demonstro em outro trabalho (Bezerra, 2022).

Published: September 2023

Abstract: Erythrina velutina Willd is a native Fabaceae with wide occurrence, mainly in the Caatinga Domain with multiple uses. This study aimed to compare the vulnerability/tolerance of seeds of four accessions of E. velutina to osmotic stresses. Four replications were conducted with 25 seeds, germinated in osmotic solutions of NaCl or PEG up to -1.73 MPa. Seeds that did not germinate after 14 days were recovered in distilled water. Obtained data were fitted in Boltzmann curves and t50 and synchrony were evaluated. A probit analysis was performed, and hydrotime and halotime models were constructed. In distilled water, the germination curve was similar for all accessions. When the concentration of salt or PEG in the substrate increased, the accessions differentiated into two groups. Two accessions - Jutaí 2012 and Jutaí 2015 - maintained high germination up to -0.86 MPa NaCl, while Caboclo 2008 and Caiçara 2011 accessions presented a lower germination speed. The hydrotime and halotime analyses separated the germination response of accessions according to their physiological quality and tolerance to osmotic and saline conditions. Seeds viability was maintained at both stresses, since germination was reestablished at distilled water, thus constituting a crucial response for this species’ survival and conservation.
Influence of SiO2, Al2O3 and TiO2 nanoparticles on okra seed germination under PEG-6000 simulated water deficit stress

Published: September 2023

Abstract: A comparative study for evaluating the influence of metal oxide nanoparticles (MONPs) (Al2O3, TiO2, and SiO2) on seed germination and seedling growth in okra was implemented under water deficit stress stimulated by PEG-6000. The results revealed that additive of SiO2 nanoparticles (SNPs) and Al2O3 (ANPs) have significant positive effect on seeds germination, while a reduction of that were observed by using TiO2 nanoparticles (TNPs) at 50 mg.L-1 concentration under 5% PEG-6000 stimulated drought stress as compared to that without MONPs. Further, relative to non-MONPs treatment, all the tested MONPs dramatically enhanced the drought stress tolerance in okra seedlings due to the improvement of morphological growth despite a few traits were inhibited under certain water deficiency to some degree. Improvement of drought resistance induced by TNPs and ANPs were found to be higher than that by SNPs. Our finding provides a promising approach to cope with water scarcity, as application of metal oxide nanoparticles to be a potential option to protect okra plants against drought stress.
Campo dinâmico vocal: avaliação da funcionalidade da voz
Authors: Behlau Mara , Madazio Glaucya , Yamasaki Rosiane
Published: September 2023

RESUMO O campo dinâmico vocal (CDV) é uma estratégia de avaliação vocal perceptivo-auditiva e acústica que oferece estimativas sobre a biomecânica e a aerodinâmica da produção vocal por meio da realização de tarefas de variação de frequência e de intensidade e do uso da espectrografia acústica da voz. Esse relato de experiência tem como objetivo demonstrar a aplicação do CDV na avaliação da funcionalidade vocal de indivíduos disfônicos e não-disfônicos, com foco especial na musculatura laríngea. As tarefas fonatórias envolvem emissão de vogal sustentada e/ou de fala encadeada em três intensidades autosselecionadas (habitual autorreferida, fraca e forte) e em três frequências (habitual autorreferida, aguda, grave), além do glissando. As tarefas de variação de intensidade e de frequência possibilitam a avaliação da musculatura laríngea no controle da adução glótica e do alongamento e encurtamento das pregas vocais. A tarefa de variação de frequência permite também a análise da musculatura extrínseca no controle da posição vertical da laringe no pescoço. Enquanto a vogal sustentada avalia a funcionalidade vocal com foco na laringe, a fala encadeada permite a avaliação dos ajustes articulatórios empregados. A aplicação do CDV será demonstrada por meio de pranchas espectrográficas de indivíduos normais e disfônicos. Indivíduos vocalmente saudáveis realizam as tarefas do CDV de forma equilibrada, com qualidade vocal adequada e sem esforço fonatório, denotando boa funcionalidade vocal. Por outro lado, indivíduos com dificuldade na realização das tarefas do CDV, com piora da qualidade vocal e/ou com aumento da tensão muscular, podem apresentar funcionalidade vocal alterada.

Método Trata-se de uma pesquisa primária, observacional, longitudinal e prospectiva. Para isso, foram aplicados os questionários Speech Spatial Qualities Questionnaire e o Expected Consequences of Hearing Aid Ownership que buscam verificar o desempenho auditivo em situações complexas de escuta e a expectativa quanto ao uso de AASI, respectivamente. A amostra se deu por conveniência com indivíduos adultos de 53 a 72 anos. Resultados No desempenho auditivo, observaram-se maiores dificuldades em situações desfavoráveis como na fala e fala no ruído, seguidas por maior facilidade em localizar a fonte sonora, qualidade e naturalidade do som. Para as expectativas quanto ao uso do dispositivo de amplificação, as variáveis com valor de correlação significativa foram idade expectativa geral com o uso do AASI, e idade em relação aos seus aspectos positivos. Não houve associação estatisticamente significativa entre os scores de desempenho em situações complexas de escuta e as variáveis analisadas. Conclusão A perda auditiva mínima pode influenciar negativamente em situações comunicativas cotidianas, como também, a expectativa dos indivíduos com perda auditiva mínima quanto ao uso do AASI mostrou-se elevada. Além disso, o desempenho auditivo nos indivíduos desse estudo não apresentou correlações com idade, gênero e escolaridade da amostra.

Published: September 2023

ABSTRACT Purpose To develop and validate an experimental verbal episodic memory task in Spanish. Methods Six encoding blocks were elaborated, three deep and three superficial, each one with different demands of cognitive effort. The blocks were reviewed by four expert judges and tested in a pilot application. The agreement was assessed on whether the task allowed combined processing level and cognitive effort to be manipulated during incidental encoding of words, as well as clarity of instructions, examples, and workflow. Results Variables such as lexical availability, metrics, and strength of association were useful to differentiate the cognitive effort between each block. The judges agreed that the processing blocks allowed a combined manipulation of the level of processing and cognitive effort and that the instructions are precise. After the pilot, the participants agreed that the instructions, examples, and way of working were easy to understand and perform. Conclusion The results provide evidence of validity related to the content for the proposed experimental task, thus becoming a viable alternative to consider in research aimed at identifying environmental factors that contribute to compensating the defects shown by episodic memory with age.
As condições discursivas de (in)determinação do “agressor de mulheres” na justiça penal
Authors: Silva José Remon Tavares da
Published: September 2023

Resumo O objetivo do artigo é abordar a formação discursiva do “agressor de mulheres” como objeto de intervenção da justiça penal. A metodologia empregada adapta algumas das contribuições de Dominique Maingueneau para a análise do discurso sobre a heterogeneidade discursiva: a intertextualidade e interdiscursividade. O estudo confronta campos discursivos distintos - o feminista e o criminológico - para compreender como, dessa interpenetração, emerge o “agressor de mulheres” como objeto de intervenção penal. Baseado na análise de um caso de violência doméstica na cidade de Recife, o presente estudo explora o debate sobre estupro praticado por conhecidos, denunciado no campo discursivo feminista desde os anos de 1960 e que, ao atravessar o sistema de segurança e de justiça penal, aciona outro campo discursivo, o criminológico punitivista. Este último, individualizando responsabilidades, reifica, na figura do “agressor de mulheres”, o crime e a própria ordem patriarcal. Essa figura de “agressor de mulheres” termina por se constituir como a chave que permite transitar da denúncia feita pela “vítima” para a efetiva incriminação em circunstâncias bastante ambíguas de acusação. Assim, uma figura de caráter excepcional passa a incorporar e sustentar, naquela interpenetração de distintos campos discursivos, a própria ordem patriarcal.
UNIVERSIDADE EM QUESTÃO: AS INSTITUIÇÕES COMUNITÁRIAS E A DIMENSÃO FORMATIVA DA GESTÃO
Authors: Lopes Maura Corcini , Schuler Betina , Casagranda Edison Alencar , Rossetto Miguel da Silva
Published: September 2023

RESUMO Este artigo constitui-se em um ensaio teórico em que se propõe uma conversação com base na filosofia da educação objetivando pensar a dimensão formativa da gestão em universidades comunitárias e suas especificidades como uma forma de atuação comprometida com a produção do conhecimento e a criação de outras possibilidades de vida. Para tanto, realizamos um diálogo com o clássico conceito de universidade, fundamentado em um diagnóstico do presente marcado pela racionalidade neoliberal, que reduz a formação humana a um léxico empresarial focado em desempenho rapidamente aplicável. Com isso, propomos uma reflexão sobre a necessidade de pensar o acesso ao ensino superior em um país desigual como o nosso, a educação como bem comum e a vida em uma dimensão mais coletiva e comunitária. Entendemos que a gestão não tem, nesse caso, apenas função administrativo-burocrática; ela assume a dimensão intelectual para pensar os efeitos éticos, estéticos e políticos de suas ações nas regiões de atuação e também de modo mais global.

Abstract Introduction The hyperboloid is a masticatory device made of silicone with an hourglass (hyperbolic) shape that has been used as an aid to jaw functional orthopedic therapy. Objective To evaluate whether the hyperboloid device affects electromyographic (EMG) activity of the masticatory muscles during jaw movements in individuals with temporomandibular joint disorders (TMD) compared to controls. Methods The study sample consisted of 49 participants divided into two groups: mild, moderate and severe TMD (TMD group; n = 25) and a control group (n = 24). We evaluated EMG activities of temporal and masseter muscles bilaterally during jaw protraction and retraction, and left and right lateralization with and without the use of the hyperboloid device. Statistical analyses were performed using two-way ANOVA with two factors: group (healthy and TMD) and situation (with or without the use of the hyperboloid). Results We found higher EMG activity in the left temporal in the TMD group and no difference in EMG activities with the use of the hyperboloid device. Conclusion The use of the hyperboloid device did not affect EMG activity of the muscles evaluated in the groups studied. We found higher EMG activity of the left temporal muscle in participants with TMD. Long-term randomized studies should be conducted in individuals with TMD to investigate the effects of functional orthopedic therapy using the hyperboloid device with visual and quantitative feedback.

Abstract Objective: to analyse the spatial distribution and trend of leprosy in municipalities of a health region in a Northeast Brazilian state. Methods: this was an ecological time-series study based on compulsory notification of leprosy cases by the municipalities covered by the Imperatriz-MA Regional Health Management Unit, between 2008 and 2017; prevalence and mean prevalence for the period were calculated; spatial analysis of the area was carried out and maps were generated using ArcGis 10.5. Prais-Winsten regression was used for trend analysis. Result: 4,029 cases of the disease were identified, and average prevalence ranged from 2.0 to 11.5 cases/10,000 inhabitants-year. The overall trend was downward. Governador Edson Lobão had the highest prevalence, 11.5 cases/10,000 inhabitants, and Lajeado Novo had the lowest prevalence, 2.0 cases/10,000 inhabitants. Conclusion: spatial distribution of leprosy cases was heterogeneous in the municipalities studied and prevalence had a falling trend.

Adentrar o deserto: A jornada utópica em “Os Detetives Selvagens” de Roberto Bolaño
Authors: Pereira João Carlos Pinho
Published: September 2023

O presente artigo tem por objetivo investigar sentidos possíveis para o deserto no romance “Os Detetives Selvagens” (1998) de Roberto Bolaño. Partindo de um olhar direcionado à exegese do deserto enquanto paisagem natural e imagem retórica concomitantemente, procura-se entender o papel latente que esse espaço tem na jornada utópica empregada por Ulises Lima e Arturo Belano em busca da poeta Cesárea Tinajero. Com isso, é possível aferir uma crítica à modernidade na obra de Bolaño pautada por uma representação do paradoxal cenário cultural latino-americano.
PAISAGENS ALIMENTARES URBANAS – UMA POSSIBILIDADE DE LEITURA DAS URBANIDADES CONTEMPORÂNEAS
Authors: Rocha Monica Guerra da
Published: September 2023

Todas as interações que os sujeitos têm com a comida (onde comem, quando, com quem, o quê, em que contextos etc.) definem e são definidas pelos territórios e as sociabilidades neles inseridas. Esta comunicação tem como objetivo refletir sobre a possibilidade de as paisagens alimentares urbanas, entendidas enquanto resultado do nexus entre sujeitos-comida-territórios, serem produtoras de espaço-tempo social, aproximando a prática e o sistema alimentar do estudo das urbanidades a partir de uma integração desta com as dimensões de espaço-tempo social propostas por Lefebvre. Os resultados são obtidos a partir de uma revisão de literatura, e ilustrada por exemplos em contextos multidisciplinares onde o nexus comida-pessoas-territórios desvenda possibilidades de ler espaço(s), tempo(s) e sociabilidade(s).

Argumenta-se que todo o comer é, ultimamente, a experiência de habitar (e digerir) o mundo, e uma forma de urbanidade que reproduz, produz e é produzida pela interseção entre o espaço produzido, o espaço praticado e o espaço representacional. Sendo o único ato fisiológico e sensorial absolutamente condicionado culturalmente, compartilhado e espacializado em uma rede possivelmente infinita de relações, comer poderá constituir uma experiência radical de produção de espaço-tempo social.
“IN MEMORIAM 1956. OKTÓBER 25.”: O MUSEU COMO INSTRUMENTO DE ESQUECIMENTO EM BUDAPESTE
Authors: Ares Graziela , Grinspum Denise
Published: September 2023

Em 2011, iniciou-se a reconfiguração da Praça Kossuth em Budapeste. O objetivo era devolver à Praça a imagem que tinha em 1944, ano em que o preâmbulo da Constituição de 2010 afirma que a Hungria perdeu a sua soberania. Em detrimento da sua contemporaneidade, autenticidade, harmonia e valor de patrimônio, a Praça e seus elementos foram reorganizados individual e coletivamente para atender à estratégia política do governo de Viktor Orbán. Nossa pesquisa investiga a transferência em 2014 do túmulo simbólico das vítimas do massacre de 1956, uma obra de Laszló Gömbos e Imre Makovesz de 1991, da Praça para a exibição-memorial “In memoriam 1956. Október 25.”, construído pelo Programa Imre Steindl no subsolo da Praça. Usamos como referência a definição de museu divulgada pelo ICOM e a literatura dos estudos da memória e da política simbólica húngara pós democratização para analisar o processo de mudança e problematizar se o museu foi utilizado como um lugar de preservação da memória ou um lugar de domínio territorial e poder. A revisão bibliográfica, as visitas à Praça na última década e a busca online por palavras-chave ampliada em método de “bola de neve” foram as nossas fontes de pesquisa. A partir de uma avaliação crítica e a problematização da nova configuração da Praça resultante das intervenções do Programa Steindl, pretendemos demonstrar como a promessa de “melhor acomodar o patrimônio e a memória” pode contribuir para o controle sobre os discursos das memórias da Revolução de 1956.
A CÚPULA DOS SISTEMAS ALIMENTARES COMO CAMPO DE DISPUTA ENTRE DIFERENTES NARRATIVAS E OS DESAFIOS EM OPERACIONALIZAR UMA ABORDAGEM SISTÊMICA DAS TRANSIÇÕES SUSTENTÁVEIS
Authors: Favarão Cesar
Published: September 2023

O objetivo deste artigo é discutir os limites das narrativas sobre as transições sustentáveis nos sistemas alimentares, a partir da análise da cúpula dos sistemas alimentares realizada pela ONU em 2021. Esse evento representou uma mudança central em relação às cúpulas anteriores ao tentar construir e operacionalizar uma narrativa sistêmica para lidar com os múltiplos desafios associados às questões alimentares atuais, a partir de três aspectos: i) mobilização de uma ampla gama de atores; ii) valorização de diferentes caminhos tecnológicos e processos de inovação; iii) e a necessidade de considerar os diferentes contextos territoriais e desafios enfrentados pelos países. Ao fazer esse movimento, a cúpula conformou um campo de embate em que diferentes atores sociais endereçaram narrativas para as transições nos sistemas alimentares, e a partir da onde pudemos identificar e discutir alguns dos limites e desafios em endereçar um tratamento sistêmico a essa questão.

Evaluation of wastewater-treatment plant (WWTP) performance is important to determine whether the plant produces an acceptable treated effluent satisfying the water quality standards for reuse. Modelling of WWTPs is required for optimising plant performance and choosing the optimum operation strategy. This study simulated the Kabd WWTP in Kuwait using the BioWin software. The plant receives 180 000 m3/day of domestic wastewater and comprises primary, secondary (activated sludge) and tertiary treatment stages. Daily data obtained from the WWTP during 2013–2018 were used for modelling plant performance under steady-state operation. The model could describe plant operation and accurately predict the effluent characteristics for the conditions examined. A high correlation (R 2 = 0.95–0.99) was obtained between the predicted and actual values of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solids as main parameters characterising wastewater. The tertiary-treated effluent consistently satisfied the water quality criteria for reuse in irrigation. Using the model could aid in securing compliance of effluent quality with the local environmental standards. Factorial analysis revealed that COD and BOD are the most important parameters describing plant performance. Reliability analysis showed that the coefficient of variability was low (0.328) at a level of reliability of 95%, leading to a high coefficient reliability of 0.631, which indicates a highly stable plant performance. It is recommended to include reliability analysis in evaluating plant performance to demonstrate consistency in the ability of the plant to produce effluents satisfying requirements set by environmental authorities.

Soils exhibit non-linear stress–strain behaviour, even at relatively low strain levels. Existing Winkler models for suction caisson foundations cannot capture this small-strain, non-linear soil behaviour. To address this issue, this paper describes a new non-linear elastic Winkler model for the uniaxial loading of suction caissons. The soil reaction curves employed in the model are formulated as scaled versions of the soil response as observed in standard laboratory tests (e.g. triaxial or simple shear tests). The scaling relationships needed to map the observed soil-element behaviour onto the soil reaction curves employed in the Winkler model are determined from an extensive numerical study employing three-dimensional finite-element analysis. Key features of the proposed Winkler model include: computational efficiency, wide applicability (it can be used for caisson design in clay, silt or sand) and design convenience (the required soil reaction curves can be determined straightforwardly from standard laboratory test results). The proposed model is suitable for small and intermediate caisson displacements (corresponding to fatigue and serviceability limit state conditions) but it is not applicable to ultimate limit state analyses.

Introduction. With increasing environmental concern nowadays, researchers are studying new alternating materials that can meet the society needs and are extracted from renewable and biodegradable resources. The various natural fibers have been investigated by researchers to replace synthetic ones. The purpose of the work. In present study, treated saccharum munja fibers considered as reinforcement material in Particulate (PC), Short and Random (SRC) and in Unidirectional (UDC) form along with AW106 Resin and HV953. The paper assesses the mechanical properties of Munya fibers (Saccharum munja). Initial six natural frequencies along with corresponding damping factors are measured to analyze the possibility of using a composite material. Research methods. A compression molding machine was used to form laminated composite materials. Surface treatment of fibers removes the dust, lignin and hemicellulose, which improves mechanical and free vibration properties. Results and Discussion. Tensile and flexural test shows the highest value of strength 170 MPa and 143 MPa in case of UDC composite, and the lowest in the case of PC. Addition of munja fiber to epoxy matrix enhances the fiber matrix adhesion bonding. The PC composite shows better value of damping than SRC and UDC composite. The highest natural frequency 43, 233, 298, 849, 918 and 1,440 Hz obtained in case of UDC irrespective of all modes. The results of the free vibration analysis show that Saccharum Munja fiber composite may be used as structural material. Analysis of variance (ANOVA) shows that the experimental results output in case of tensile and flexural teste are significant.

Introduction. Intermetallic compounds Fe2Ti and FeTi are of practical application as hydrogen accumulators (FeTi) or as magnetic materials (Fe2Ti). Due to the peculiarities of the double equilibrium diagram, the production of these intermetallic compounds by casting is difficult. Therefore, powder metallurgy methods are widely used combined with preliminary mechanical activation of the powder mixtures. The aim of the work is to investigate the possibility of obtaining single-phase compounds from powder mixtures of titanium and iron of target compositions. Research methods. Mechanically activated powder mixtures, products of combustion and subsequent annealing were studied by X-ray phase analysis, optical metallography, and scanning electron microscopy using elemental composition determination by energy-dispersive X-ray spectroscopy. Research methodology. Powder mixtures were mechanically activated for 20 minutes in an Activator 2S planetary ball mill with an intensity of 40 g and a ball/mixture ratio of 20. The mechanically activated mixtures were heated in a sealed reactor in argon media at an average rate of 85 C°/min. Results and discussion. At a temperature of about 500 °C, thermographs of thermocouples placed in a mechanically activated mixture showed a sharp rise (thermal explosion), indicating an exothermic reaction in the mixture. The rise for the 2Fe + Ti composition turned out to be more pronounced than that for the Fe + Ti composition. X-ray diffraction analysis showed that the main reaction product is the Fe2Ti compound for both mixtures. The predominant formation of Fe2Ti is explained by the greater negative enthalpy of Fe2Ti formation of compared to FeTi (−87.45 and −40.58 kcal/mol, respectively). Conclusion. High-temperature annealing of thermal explosion products did not make it possible to obtain single-phase target products. The content of secondary phases and unreacted reagents changed little after annealing. Based on the obtained results, it was concluded that the thermodynamic factor (the enthalpy of formation of the intermetallic compound) is the main one that determines the phase composition of the synthesis products in powder mixtures of titanium and iron.

Introduction. Rails’ grinding in the conditions of a railway track is a priority for extending its life cycle due to the timely removal of tread surface defects and formation of required transverse profile. Today, 14 RSHP-48 rail grinding trains are used in Russia. At the same time, most rail grinding trains are ending its service life. Therefore, the development of a fundamentally new rail grinding train with increased efficiency is an urgent task. Siberian transport university is working together with the Kaluga plant “Remputmash” to create a new rail grinding train named RSHP 2.0. The rail grinding train RSHP 2.0 is based on the technology of high-speed rail grinding, which is based on increasing working speed of rail grinding train by increasing rotational speed of grinding wheels and setting the angle of attack. The aim of this work is to study rails’ grinding modes on a specially designed installation URSH, which implements the technology of high-speed grinding rails by increasing speed of grinding wheels rotation up to 5,000 rpm. Research methods. Grinding wheel speed control was carried out by IT-5-ChM “Termit” electronic tachometer and “Megeon 18005” laser tachometer. The angle of attack of grinding wheel was measured by digital, three-axis accelerometer-inclinometer ATst 90. The force of pressing grinding wheel to the rail was evaluated by strain-resistive sensors M50-0.5-C3. The measurement of head rail transverse profile before and after grinding and evaluation of metal removal were carried out by a PR-03 rail profiler. The width of grinding track was controlled by ShTsTs-I-300-0.01 caliper. The surface roughness of rail sample after machining was measured by TR 200 portable instrument. Results and discussion. Based on research results of CRS, the parameters of the working equipment of designed grinding rail train, which implements the technology of high-speed rail grinding, the influence of grinding modes on the formation of the quality parameters of the machined rail surface are established, and the optimal values of the forces of pressing the grinding wheel to the rail are determined.
