Da plasticidade do crime ao acesso à informação em relatos de homicídios: vicissitudes decorrentes de experiências violentas
Authors: Kornalewski Alex Medeiros , Farias Francisco Ramos de
Published: May 2021

RESUMO O artigo disserta sobre as múltiplas implicações decorrentes do crime, sua relação com os efeitos traumáticos e suas consequentes rupturas nas cadeias de memórias. A metodologia aplicada é a análise a partir de dois relatos de pessoas distintas que praticaram o ato de homicídio, haja vista a multiplicidade de violências que são narradas, intencionalmente ou não, por estes sujeitos, além das experiências serem representativas do social. As investigações sobre violência estão ligadas a tríade: crime, trauma e informação, sendo estas sub-ramificações empregadas, em certa medida, na tecitura da própria violência. Verifica-se que a construção de protocolos de acesso à informação e análise das restrições informacionais é salutar para a implementação de políticas públicas para as pessoas presas ou egressas do sistema prisional.

Published: May 2021

Resumo Kiwis minimamente processados necessitam de técnicas para manter a qualidade dos frutos durante a conservação e o período de prateleira. Aditivos combinados à radiação ultravioleta podem ser uma alternativa para assegurar a qualidade das frutas por mais tempo de conservação. Neste contexto, foi proposto avaliar a eficiência do uso da radiação UV-C e diferentes aditivos na prevenção do escurecimento e conservação de kiwis ‘Bruno’ minimamente processados. As fatias de kiwi foram submetidas a soluções contendo os seguintes tratamentos: controle, ácido ascórbico a 1%; isoascorbato de sódio a 1%; ácido cítrico a 1%, depois, utilizou-se por dois minutos a radiação UV-C na intensidade de 2,71 kJ m-2. As bandejas foram armazenadas em câmara fria a 4 ± 1 ºC de temperatura, com umidade relativa de 85% a 90%, e armazenadas por períodos de 3, 6 e 9 dias. Avaliaram-se perda de massa, coloração da polpa, sólidos solúveis, acidez titulável, incidência de podridão, compostos fenólicos totais e atividade antioxidante. O uso de aditivos melhora a conservação do kiwi minimamente processado, com destaque para o isoascorbato de sódio e o ácido cítrico. Os frutos de kiwi da cultivar ‘Bruno’ podem ser armazenados por até 6 dias sob refrigeração com o uso de aditivos. Após esse período, a perda de massa é elevada. O uso de UV-C não alterou a qualidade dos kiwis durante o armazenamento, podendo ter seu uso dispensado.

Published: May 2021

Abstract Cowpea grains are nutritious and beneficial to health, contain about 25% of proteins, in addition to carbohydrates, vitamins, minerals, and bioactive compounds. Soaking the beans followed by cooking requires time availability that is incompatible with the current lifestyle. Consumers have opted for read-to-eat, attractive, healthy, nutritious and convenient foods, thus, transforming cowpeas into crispy expanded product is promising. This research aimed to evaluate the effect of the extrusion conditions, moisture, and temperature, on the physical characteristics of the extrudates developed from cowpea cotyledons flour (CCF): from cultivar BRS Guariba (Sorriso, MT, Brazil). The CCF was processed using twin-screw thermoplastic extruder ZSK 30 (Werner & Pfleiderer Co.) varying the moisture (16.2% to 21.8%) and temperature (124 to 166 °C) using Central Composite Rotatable design 22. The expansion index values ranged from 3.01 to 3.98, the regression model was not predictive, with the determination coefficient (r2) equal to 0.67. The independent variables studied presented significant effects, being water solubility index affected by the CCF moisture, compression force (15.63 to 47.72 N) affected by the extruder temperature, the water solubility index (28.34% to 43.67%) by moisture, while the specific volume (2.41 to 4.58 mL g-1) and the water absorption index (5.34 to 6.54 g g-1) were affected for both variables. By simulation, the maximum value of 1 was obtained through the global desirability test in the combination of an extrusion temperature of 124.21 °C and conditioning moisture of CCF of 16.28%. This condition favors obtaining extrudates with greater values for a specific volume and water absorption index, and lower values for compression force and water solubility index.

Published: May 2021

Resumo Na bananicultura, o uso de sacos impregnados por inseticida e a lavagem das pencas são técnicas que visam à qualidade dos frutos. Objetivou-se monitorar, por cromatografia em fase gasosa acoplada à espectrometria de massas, resíduo de bifentrina em bananas lavadas e não lavadas em tanques, assim como na água de lavagem dos frutos. Desde a emissão até a colheita, os cachos foram protegidos com sacos impregnados por bifentrina a 1,0 g kg-1, os quais foram retirados após a colheita, para despencamento e lavagem ou não das pencas em tanques com água, detergente e sulfato de alumínio. Os métodos Quick, Easy, Cheap, Effective, Rugged, Safe Method - QuEChERS e Extração Líquido – Líquido com Partição a Baixa Temperatura - ELL – PBT foram utilizados para extrair resíduo de bifentrina dos frutos no ponto de colheita e maduros, e da água, respectivamente. As porcentagens de recuperação de bifentrina foram 88,16%, 103,4% e 89,32%, na casca, na polpa e em casca + polpa, respectivamente, atendendo à legislação brasileira. No ponto de colheita, na casca e na casca + polpa dos frutos lavados, detectou-se 0,060 mg kg-1 e 0,010 mg kg-1, respectivamente. Quando não lavados, a concentração de bifentrina, na casca, foi de 0,31 mg kg-1 e de 0,16 mg kg-1, na casca + polpa. Não foi detectado resíduo de bifentrina na polpa, independente do estádio de maturação e lavagem, tampouco na água de lavagem. Em frutos maduros não lavados, foram quantificado 0,10 mg kg-1 e 0,040 mg kg1 de bifentrina na casca e em casca + polpa, respectivamente. A lavagem não elimina, mas reduz o resíduo de bifentrina na casca dos frutos no ponto de colheita e, quando maduros, somente os não lavados apresentam resíduo.

Authors: Herrmann Gerson , Souza Claucia Fernanda Volken de
Published: May 2021

Abstract The present study aimed to evaluate the effects of barley malt pomace addition on the characteristics of fresh pork sausages over 10 days of storage. Four fresh sausage formulations were elaborated, one with no addition of barley malt pomace (control formulation), and the other three elaborated with 3%, 6%, and 9% of pomace. The sausages were submitted to physicochemical analyses to determine ash, moisture, protein, lipid, carbohydrate, and raw fiber contents, water activity, pH, peroxide indices, and energetic value. Additionally, texture and color technological analysis and sensory analysis were performed. Sausages with 3% of malt pomace presented a protein content of 17.10% on the 10th day of storage, and raw fiber content of 2.00%; while in the control formulation these contents were 16.59% and 0.77%, respectively, with a significant difference (p ≤ 0.05) between samples, representing an increase in product nutritional value. In the hardness analysis, the control formulation had a value of 13.99 N and the formulation with 3% of pomace of 10.11 N, which shows that sausages with the addition of pomace are not as hard. In the sensory analysis, the control formulation showed about 80% acceptability in all attributes, the sausage with 3% of malt pomace had an acceptability index higher than 80% for the attribute 'global acceptance', the sausage with 6% of pomace had an index of approximately 70% and the formulation with 9% showed acceptability index of approximately 64% for the attribute 'global acceptance'. The addition of 3% of malt pomace to the sausage was the best alternative, since it had good acceptance by consumers, and provided an increased nutritional value. Our results show that the use of malt pomace in meat products is a viable alternative that helps to reduce production costs and aids in solving an environmental issue.
Application of computed tomography dose index as dosimetric parameter in dental tomography
Authors: MAURO Rodrigo Antonio Pereira , COSTA Alessandro Martins da
Published: May 2021

ABSTRACT Objective Quantify the CTDI from a reference beam, correcting this value for several beam widths from the ratio of CTDI100 values measured in the air, and verifying the underestimation of the dose comparing CTDI100 and CTDI300, applied to dental CBCT. Methods i-CAT and Prexion 3D tomographs, 100mm pencil ionization chamber, electrometer. Firstly for beam above 40 mm, CTDIW,NT from CTDIW,Ref, multiplied by the ratio of CTDIAR measurements to N.T widths and reference, was estimated. In second, CTDI100 and CTDI300 are obtained by displacing the ionization chamber along the beam with spacing intervals equal to 100 mm to cover sufficiently large integration intervals for CBCT protocols, and a comparison is made through the modified efficiency. Results CTDIAR,100,Ref averaged 53% higher than CTDIW,Ref, due to attenuation of the beam by the simulator object, and the ratio between CTDIAR,100,Ref and CTDIW,Ref is greater than 1, being this constant relationship and validating the method for dosimetry in quality control tests. For the second method, CTDI100 greatly underestimates the dose deposited on the central axis, where CTDI300 covers all beam sizes and stands out in relation to CTDI100 to more accurately quantify the radiation levels emitted. Conclusions The IEC method is applicable to quality control, facilitating practice, and optimizing time and resources. CTDI300 is a better dose descriptor than CTDI100, and should be implemented for CBCT modalities when used.

Published: May 2021

ABSTRACT Every day, professionals who work with esthetics are faced with the challenge of meeting patients expectations who longs for a perfect smile, where every detail must show harmony and naturality. In this context, composite resin reanatomization is widely indicated for small corrections of color and shape in one or more dental elements, for diastema closure and sometimes for correction of small dental misalignment. The case report presented here discuss the planning and treatment for the esthetic and functional improvement of the dental units 1.1, 1.2, 2.1 and 2.2, by making direct restorations in composite resin. The patient sought the Faculty of Dentistry of UFBA in search of esthetic treatment, reporting dissatisfaction with the smile. During an evaluation, the thickness and size of the upper back teeth were dissonant, besides of the interincisal diastema and a discrete gyroversion of the lateral incisors, which together compromised the esthetic area of the smile. Therefore, the proposed treatment for solving this clinical situation was direct esthetic rehabilitation with composite resin in units 1.2 to 2.2. After obtaining the study models, it was accomplished diagnostic waxing and silicone guide as auxiliary resources on the planning and restorative stage. Nanoparticulate composite resins were used, making a stratification technique to obtain a harmonic result. The treatment was able to reproduce the esthetic and natural appearance of the teeth, through a conservative alternative, fast and with an excellent cost-benefit relation when compared to the indirect techniques.

ABSTRACT Objetive To determine the percentage of correctness of the Orbital Index (OI) for estimation of sex, ancestry and age in Brazilian skulls. Methods Cross-sectional study of 183 human dry skulls from the southeastern Brazil. A total of 100 skeletons were males and 83 females; of which 36 were aged up to 39 years, 60 aged between 40 and 59 years, and 87 aged 60 years or older. As for ancestry, 103 were from white, 51 mixed race, and 29 black individuals. The OI was calculate by the formula = height/width x 100. The data were submitted to Student’s t test, F (ANOVA), Tukey and Kruskal Wallis tests as well as to discriminant analysis, with a 5% significance level. Results The sample was characterized as mesoseme, with a mean age of 56.62 (±19.97) years. No significant difference was observed (p=0.511) between the OI in females (right: 86.43 ± 6.58 and left: 86.70 ± 5.93) and males (right: 85.78 ± 6.69 and left: 86.37 ± 6.20). There were no significant differences between age, ancestry and the variables analyzed (p>0.05). The right and left orbital widths were significantly dimorphic between sexes (p<0.001). The percentage of correctness of the method for estimation of sex, age and ancestry was found to be 65.6%, 43.7%, and 43.6%, respectively. Conclusions The OI is not an appropriate method for estimation of sex, ancestry and estimation of age in this Brazilian sample. The methodology should be expanded to other population groups so that it can be improved.

Dimorfismo sexual, ¿natural? Una reinterpretación crítica de las diferencias biológicas
Authors: Ciccia Lucía
Published: May 2021

Resumen El presente trabajo expone una interpretación sexual dimórfica de las diferencias biológicas en la especie humana, que resulta de la lectura androcéntrica de los cuerpos que caracterizó la ciencia moderna. En contraste con esta lectura, se muestra cómo las prácticas sociales asociadas con los roles de género pueden traducirse en diferencias biológicas que “se ajustan” a una lectura dimórfica. Sobre la base de estos hechos, se propone que, si existen ciertos correlatos entre genitalidad y diferencias biológicas, los mismos no necesariamente son causados por los procesos de diferenciación sexual, sino por vínculos estadísticos dados por los estereotipos normativos de género. Las conductas implicadas en tales estereotipos se expresan biológicamente, y los roles de género crean muchas de las diferencias biológicas que hoy se asumen como naturalmente dimórficas.

RESUMO Objetivo verificar a aplicabilidade do THS em mensurar e diferenciar as queixas de zumbido, perda auditiva e tolerância ao som. Método Foi aplicado o questionário THS, composto por 4 questões sobre zumbido, 4 sobre perda auditiva e 1 sobre tolerância ao som. Previamente, todos os participantes realizaram uma bateria de exames de diagnóstico audiológico e foram divididos em grupos: audição normal bilateral com média até 25dB, com e sem queixa de zumbido (Grupos 1 e 3); diagnóstico de perda auditiva sensório neural de grau leve a moderado (26dB a 60dB), sem uso prévio de aparelho de amplificação sonora Individual (AASI), com queixa de zumbido crônico (≥6 meses) e também indivíduos sem queixa de zumbido (Grupos 2 e 4); idade igual ou superior a 18 anos. Resultados Foram incluídos no presente estudo 70 indivíduos. Em relação a análise do total entre os grupos pelo teste Kruskal-Wallis foram encontradas diferenças significativas nas seções sobre zumbido e perda auditiva, mas não houve significância da seção sobre tolerância ao som. Em relação às questões sobre zumbido apenas os grupos 3 e 4 pontuaram. Quanto às questões referentes à perda auditiva, os grupos sem perda (grupos 1 e 3) foram os que menos pontuaram. Em relação a questão do THS sobre tolerância ao som, o grupo 3 foi o que mais pontuou. Conclusão o questionário THS se mostrou como uma possível ferramenta para auxiliar na compreensão e diferenciação das queixas auditivas.

Published: May 2021

Resumo Introdução No Brasil, a assistência pública voltada aos trabalhadores acometidos por doenças ou acidentes, incapazes de exercerem sua profissão, mas com potencial laborativo residual, é prestada pelo Instituto Nacional do Seguro Social (INSS), por meio do Programa de Reabilitação Profissional (PRP). Objetivo Compreender a contribuição do PRP na reinserção do trabalhador no mercado de trabalho. Método Trata-se de um estudo de caso, documental, transversal e descritivo, que teve como fonte de dados 592 prontuários de trabalhadores encaminhados ao PRP de uma Agência do INSS da região Sudeste do Brasil, no período de 2007 a 2012, dos quais foram extraídos dados sociodemográficos, acadêmicos e profissionais, além de entrevistas com oito usuários reabilitados. Resultados Os resultados apontaram que, dentre os segurados encaminhados ao Programa, 48,5% foram elegíveis, 34% considerados reabilitados e, destes, 49,02% estavam empregados. Os entrevistados não apontaram relação direta entre o PRP e sua reinserção no mercado, mas afirmaram que os recursos utilizados foram importantes para conquistarem, senão um emprego, ao menos reconhecimento pessoal e profissional. Apesar da taxa de empregabilidade dos trabalhadores reabilitados ser satisfatória em comparação com aqueles encontrados em estudos de países desenvolvidos e com sociedades menos desiguais, esse aparato ainda não se tornou um aliado efetivo do trabalhador brasileiro. Conclusão É essencial que os profissionais do INSS e reabilitados tenham uma postura mais ativa no processo reabilitatório. Deve-se considerar a promoção de ações intersetoriais que busquem articular as políticas públicas relativas à área e que abarquem a complexidade do processo de retorno ao trabalho.

Published: May 2021

ABSTRACT Objective: Cervical spondylotic myelopathy (CSM) is the main cause of spinal dysfunction in adults. The type of surgical approach to treatment is not well defined in the literature. The objective is to report the results obtained through isolated posterior decompression in patients with a previous indication of the combined approach for the treatment of cervical spondylotic myelopathy. Methods: This is a therapeutic study with level of evidence II, according to the Oxford classification table. Ten patients who underwent isolated posterior approach surgery for the treatment of cervical spondylotic myelopathy were evaluated through imaging and questionnaires (visual analog scale, mJOA-Br scale – Brazilian Portuguese version of the Modified Japanese Orthopedic Association Scale, and Neck Disability Index (NDI)), comparing pre- and postoperative results. Results: Late evaluation of the 10 patients was performed in the period ranging from 24 to 36 months (mean of 30.3 months ± 7.25) following surgery. The comparison of the clinical and radiological parameters in all patients showed a statistical difference in relation to the preoperative scales applied and to the degree of cervical lordosis (p <0.05), evidencing improvement after decompression and posterior fixation of the cervical spine. Conclusions: The isolated posterior approach (decompression, fixation and arthrodesis) allowed the clinical and radiological improvement of patients with cervical spondylotic myelopathy and who had an indication of the complementary anterior approach. Level of evidence II; Retrospective study.

ABSTRACT Objective: Tuberculosis (TB) represents one of the top ten causes of death in the world. Its insidious onset and nonspecific symptoms usually result in delayed diagnosis. The objective is to evaluate the characteristics of patients with tuberculous spondylodiscitis in follow-up at a South American reference hospital. Method: Retrospective evaluation of the medical records of patients of both sexes and between 0 and 80 years of age diagnosed with tuberculosis of the spine between 2009 and 2018. The variables were analyzed based on groups: epidemiological, clinical, laboratorial, microbiological, imaging tests and treatment. Results: Total of 26 cases, about 80.8% male, mean age 41.6 ± 22.46 years. Axial pain was the most prevalent symptom (84.6%), the VAS score was 6.85 ± 2.87. The mean time between symptom onset and diagnosis was 23.8 ± 24.1 weeks (4-96). The most affected region was the thoracic spine (50% of the cases). Most participants (61.4%) had no change in neurological function (Frankel D and E) at the beginning of treatment and after 6 months, and 84.5% improved. During treatment 34.6% required surgery and the main indication was isolated neurological deficit (55.5%). The most frequently performed procedure was decompression and arthrodesis (55.5%). The average time to cure was 12.0 ± 8.8 months (8-48). Conclusion: Disease with insidious onset, nonspecific symptoms, high frequency of negative microbiological tests in cases with the disease. A small number of the cases required surgical treatment and most of them achieved good neurological recovery. Level of evidence IV; Case series.

ABSTRACT Objective: To analyze the cervical sagittal parameters of patients with rheumatoid arthritis (RA) and compare them with the parameters obtained from healthy patients in a sample of the Brazilian population. Methods: Epidemiological data were collected and 72 radiographs of the cervical spine in the sagittal plane were evaluated by measuring the cervical sagittal parameters COG-C7 (distance measured between the center of gravity of the head and the C7 plumb line -cranial offset), C2-C7 lordosis (vertebrae from C2 to C7), T1S (T1 slope), TIA (thoracic inlet angle) and NT (neck tilt). Statistical analysis was performed using the Student’s t and chi-square tests. Results: The TIA and NT values in the RA group were 88.8° ± 12.6° and 54.5° ± 9.3°, respectively, while for the control group, they were 77.7° ± 7.9° and 50.5° ± 7.7°, respectively, the RA group values being statistically higher than the control group values (p <0.001 and p = 0.050, respectively). The values obtained for COG-C7, C2-C7 lordosis and T1S for the RA group were 9.4 ± 16.4mm, 25° ± 22.4° and 2.6° ± 10.1°, respectively, while for the control group they were 11.8 ± 17.6mm, 26.8° ± 12.5° and 30.9° ± 8.4°, respectively. Conclusions: Patients with RA present changes in the thoracic inlet parameters as compared to the control group, with a statistically significant increase in the TIA and NT values, outlining a characteristic compensatory pattern for maintaining cervical sagittal balance.

ABSTRACT Objective: Adolescent idiopathic scoliosis (AIS) is a spinal deformity that can cause cardiorespiratory dysfunction, contributing to decreases in tolerance for aerobic exercise (TAE) and in functionality. The objective is to assess the TAE and lung capacity of patients who underwent corrective AIS surgery in the pre- (PRE) and postoperative (POST) periods. Methods: Sixty individuals, PRE (n=30, age: 18.5±2.4 years) and POST (n=30, age: 24.5±4.5 years), participated in the study. The forced vital capacity (FVC), the forced expiratory volume in the first second (FEV1) and the FEV1/FVC ratio, as well as the maximum inspiratory and expiratory pressure were verified. The TAE was assessed by the distance travelled in the 6-minute walk test (6MWT), together with blood pressure, heart rate, respiratory rate and peripheral oxygen saturation measured at the beginning and at the end of the test. Results: A mild restrictive pattern in lung function and reduced expiratory muscle strength were observed in both groups, but with no difference between the PRE and POST groups. No difference was found between the PRE (534±67.1 m) and POST (541± 69.5 m) groups for the distance travelled in the 6MWT, though both were below the predicted percentage (82.8±10.0% and 84.8±10.9%, respectively). Hemodynamic and respiratory changes caused by the 6MWT were observed, except for the peripheral oxygen saturation. Conclusion: The results suggest that even after surgical correction, patients with AIS continue to have low TAE.

ABSTRACT Objective: In the last three decades, there have been great advances in the surgical treatment of adolescent idiopathic scoliosis. There are few studies that focus on the long-term clinical and radiographic results of AIS operated on with pedicle screws that also consider psychological repercussions. Methods: We conducted an observational longitudinal study. We reviewed the AIS cases that were operated on with pedicle screws in our center between January 2009 and December 2010. We conducted follow-up until July 2019. A short questionnaire was administered to assess patient satisfaction and the long-term impact from both psychological and functional points of view. Results: A total of 19 patients met the inclusion criteria. The mean preoperative Cobb was 58°, the postoperative was 23° and at the end of follow-up it was 26°. No major complications were reported. Ninety percent were very satisfied with the overall results of the surgery. Ninety-five percent had no limitation for sports or daily activities and 90% were satisfied with the cosmetic results. Conclusion: The short- and long-term radiographic evolution in patients treated with third generation material presented good clinical results. In 3 cases (16%) loss of correction greater than 10% was reported. The overall satisfaction index and cosmetic results were very good at the end of follow-up despite the low correction rate (60%). There were no major complications and the incidence of functional limitation and pain at the end of the follow-up was very low. Level of evidence IV; Review article.

Method: Cross-sectional study conducted in Intensive Care Units of two public hospitals, reference centers for cardiology, located in São Paulo city, with 123 patients. Demographic and clinical data from patients’ medical records were collected and lesions were identified through skin inspection. The data were analyzed through descriptive statistics and bivariate and multivariate analysis (Classification and Regression Tree). Results: Medical adhesive-related skin injury was presented by 28 patients, which amounts to a 22.7% prevalence. Its main causative agent was transparent polyurethane film (46.9%) and the cervical region was the most affected area (25.1%). From the multivariate analysis, the associated factors were found to be the presence of serum urea higher than or equal to 48.5 mg/dL and platelets lower than 193,500 mm3 or platelets higher than or equal to 193,500 mm3 and systolic blood pressure higher than or equal to 122 mmHg. Conclusion: This study has contributed to knowledge related to the epidemiology of this type of injury, favoring preventive care planning.

Abstract Structural health monitoring can detect anomalies in time, allowing the implementation of more efficient maintenance and repair actions in special engineering structures. An alternative in the monitoring and evaluation of structures in civil engineering is the use of optical fibers inscribed with Bragg gratings (FBG or Fiber Bragg Grating). This paper aims to compare available techniques to estimate the elastic module of cementitious composites, as well as contribute to the application of optical fiber sensors in the monitoring of strain, natural vibration frequency, damping coefficient and elastic modulus of mortar beams. The FBG sensors manufactured and calibrated by the authors presented a good precision for measuring those parameters in mortar samples. The results show that FBG sensors and strain gauge sensors present a similar result for strain and estimation of the elastic module (static and dynamic), therefore, bare FBGs could be further investigated for non-destructive testing.

Published: May 2021

abstract: For a controlled granulometry, this study evaluates the effect of nano-silica on mechanical and rheological properties, as well in the microstructure of Portland cement matrices containing a fixed amount of supplementary cementitious materials and three different types of cements. The rheological behavior of cement pastes was evaluated by rotational rheometry and mechanical performance was measured througth the compressive strength. The microstructure was analyzed by intrusion mercury porosimetry and scanning electron microscopy. There was an increasing on the viscosity of the cementitious matrices, as a consequence of the reduction in the inter particle separation of these suspensions. The optimum content of nano-silica varied according to Ca/Si ratio of Portland cement matrices containing supplementary cementitious materials. The use of nano-silica allowed to modify the pore size distribution of cementitious matrices. And the structure of nano-silica in cementitious matrices has occurred in layers or agglomerates of nano-particles covered by hydration products.

Published: May 2021

abstract: Ultra-high performance concretes with steel microfibers have been studied in depth with the aim of producing more efficient and durable structures. The performance of these materials depends on the characteristics of the interface between microfibers and cementitious matrix. This research investigates the micro-nanomechanical properties of the interfacial transition zone between the steel microfibers and the matrix of ultra-high performance cementitious composite. The effect of the water/cement ratio and distance from the microfiber were analyzed. The results confirm the formation of high-density calcium-silicate-hydrate (HD C-S-H) matrix at higher concentrations than low-density calcium-silicate-hydrate (LD C-S-H) for w/c ratios of 0.2 and 0.3. The properties in cementitious matrix interface with steel microfibers were very similar to that measured for the cement paste, and no significant difference was observed regarding the distance to the microfibers in relation to the elastic modulus, hardness and chemical composition. Thus, the authors can conclude that the formation of a less resistant region does not occur at the interfacial transition zone cement paste/microfibers.

Abstract In the last decades, several studies have been developed regarding structures composed by frames infilled with masonry walls, proving the increase of lateral stiffness by the infill. In this work, an analysis was carried out, based on design codes which adopt the equivalent diagonal strut method, to compare theoretical results with experimental ones of tests performed on steel frames infilled with concrete block masonry. Two of the three assessed codes specify lateral stiffness smaller than that measured from experimental testing, as safety measures for design. Regarding the masonry ultimate loads, the two specifications analyzed yielded similar values of critical force, although they pointed out different failure modes. The equivalent diagonal strut method has been proved to be a simple and useful tool for considering masonry walls and it should be used in case of reduced horizontal loads, prior to initial cracks of the infill wall.

Abstract: Carbon nanotubes (CNTs) are potential candidates to enhance the heat balance of concrete, reducing internal stresses caused by differential heating in massive concrete elements. The higher the aspect ratio (AR) and content of CNTs, the greater the expected thermal conductivity (TC). However, high AR may impair the proper dispersion of CNTs in cementitious matrix, potentially harming the workability and mechanical strength of the composite. This work evaluated the effect of the AR (35, 250, 900, and 3500) and content (0.05% and 0.10%) of CNTs on the TC, rheology (squeeze flow), and mechanical strength of cement paste. Results showed that 0.05% CNT increased the TC of paste by up to 15% for AR of 250, but further increasing AR progressively reduced the TC of the composite. In turn, 0.10% CNT incorporation did not result in significant TC gains. The yield stress and viscosity of the mixes progressively increased as CNTs content and AR increased, by up to 119% compared with plain cement paste. No significant differences were observed in 28-day compressive strength with 0.05% CNT incorporation, while 0.10% CNT led to slight strength reductions for some mixes. Regarding flexural strength, 0.05% incorporation of either CNT decreased the strength of the mixes while 0.10% incorporation generally compensated this reduction, except for the lowest aspect ratio. Overall, CNTs with intermediate AR (around 250) was effective in improving the thermal conductivity of cement paste, increasing it by 15% with relatively low content (0.05%) while did not significantly impair the fresh and mechanical performance of the composite.
PERFORMANCES OF THE BRAZILIAN UNIVERSITIES IN THE “U-MULTIRANK” IN THE PERIOD 2017-2020
Authors: Prado Antonio
Published: May 2021

The present paper makes an evaluation of the performances of the Brazilian Universities in the “U-Multirank”, in the range from 2017 to 2020. The “U-Multirank” is a multidimensional academic ranking created in Europe, presenting results since 2014. It gives a new multidimensional approach that has the goal of showing the weakness and strengths of each University, using five Dimensions. In this way, it does not classify Institutions in a single ranking. This model is very important in Brazil nowadays, because it is the model that Capes is using to prepare the new evaluation of the post-graduate system in Brazil. Of course there will be adaptations, but a general study of this ranking is important to give an idea of its future use. Only 20 Brazilian Universities are listed in this ranking in 2020. It is a small number, but it is significant in regional terms, since South America has only 35 Universities listed.
Recommendation of RILEM TC 261-CCF: test method to determine the flexural creep of fibre reinforced concrete in the cracked state
Authors: Llano-Torre A. , Serna P.
Published: May 2021

To date there is no clear consensus about how creep of cracked FRC structural elements should be considered. In recent years, different methodologies have been developed for multiple stress cases. The absence of a standardised methodology to evaluate flexural creep in the cracked state has hindered general comparisons and conclusions that could lead to significant advances in this topic. Since 2014, the study of the creep behaviour of cracked FRC has been coordinated by the RILEM TC 261-CCF. All the available creep methodologies were analysed in terms of procedure, equipment and results. A comprehensive Round-Robin Test (RRT) on the creep behaviour of cracked sections of FRC was proposed and undertaken by a total of 19 participant laboratories from 14 countries all over the world. The analysis and conclusions of the RRT results and the different methodologies provided the basis for this recommendation. This recommendation focuses on the test method to evaluate the flexural creep of FRC specimens in the cracked state. Guidelines on specimen production, detailed test equipment, experimental setup and test procedure as well as the definitions of the most relevant parameters are provided.

Published: May 2021

El presente estudio se propuso investigar perfiles de usuarios de redes sociales que presentan conductas disruptivas online. Para tal fin se diseñó un índice que permite evaluar el nivel en el que se presentan dichas conductas y se analizó la relación entre la intensidad de la conducta disruptiva online con variables sociodemográficas, motivos de usos de redes, variables de personalidad (normales, patológicas y rasgos vinculados a tríada oscura), bienestar y malestar psicológico. Participaron 858 adultos (421 hombres y 437 mujeres) que tenían en promedio 39.16 años (DE = 14.14). Para la recolección de datos se administraron: Dark Triad Scale, Big Five Inventory, Inventario para Trastornos de la Personalidad para el DSM-5, Mental Health Continuum y Depression, Anxiety and Stress Scale, y se diseñaron dos escalas: Índice de Conductas Disruptivas Online y Motivos de Utilización de Redes Sociales. En cuanto a las variables sociodemográficas, se halló que los más jóvenes de sexo masculino y que no trabajaban eran quienes presentaban un mayor nivel de comportamientos disruptivos online. En cuanto a los motivos de uso de redes, se observó que preferían usarlas con fines meramente exhibicionistas, de ocio o para iniciar nuevas relaciones. Por otro lado, en relación con rasgos de personalidad, aquellos que diferenciaban los perfiles en cuanto a la intensidad de las conductas disruptivas fueron: bajos niveles de responsabilidad y altos niveles de desinhibición, narcisismo y maquiavelismo. Por último, se demostró que presentar este tipo de conductas se asocia con mayor nivel de estrés y menor de bienestar social.

Published: May 2021

Los problemas de salud mental son un tema relevante en todo el mundo. Pese a los avances, es necesario continuar trabajando para mejorar la calidad de vida del colectivo. La educación y el apoyo entre iguales son estrategias muy adecuadas para contribuir a su integración socio-laboral. Se ha realizado una revisión bibliográfica en bases de datos y páginas web para identificar experiencias españolas de formación de personas con Trastorno Mental Severo (TMS) basadas en el apoyo entre iguales. Se han encontrado siete experiencias de formación para el colectivo, cinco de ellas centradas en el apoyo entre iguales y otras en la figura de el/la asistente personal.
El número de experiencias encontradas en España es muy reducido. Aunque los objetivos son comunes, se observan enfoques diferentes (entorno sanitario, laboral, social) que pueden ser muy relevantes para el diseño y aplicación de otras experiencias en diferentes contextos.
