RESUMO: Actinobacillus pleuropneumoniae é o agente causador da pleuropneumonia suína, uma doença respiratória contagiosa associada à alta morbidade e perdas econômicas. Embora a antibioticoterapia ajude a controlar a disseminação do patógeno na fazenda, a resistência a várias classes de antibióticos tem sido relatada e o tratamento pode ser prejudicado pela capacidade bacteriana de formar biofilmes. Isso aumenta a necessidade de abordagens terapêuticas alternativas, que incluem o uso de compostos naturais com atividades antimicrobianas e/ou antibiofilme. Neste trabalho, analisamos, pelo método de microdiluição em caldo nutriente, os efeitos inibitórios e bactericidas dos óleos essenciais obtidos de dezoito plantas medicinais brasileiras populares e/ou temperos contra isolados clínicos de Actinobacillus pleuropneumoniae. Então, concentrações subinibitórias dos óleos ativos foram testados quanto a suas atividades antibiofilme, analisados pelo método do cristal violeta. Dentre os dezoito óleos testados, oito (extraídos da canela, coentro, hortelã-pimenta, hortelã, tomilho, manjerona, eucalipto e louro) apresentaram atividade bacteriostática e bactericida contra todos os isolados, e concentrações subinibitórias de cinco deles romperam biofilmes pré-formados em até 80%, além de inibirem fortemente a formação de biofilmes. A composição química desses óleos foi avaliada por cromatografia gasosa/espectrometria de massa (CG/MS) e é apresentada, indicando que suas propriedades bactericidas e antibiofilme estavam principalmente associadas à presença de monoterpenos e fenilpropanóides. Este é o primeiro relato de óleos essenciais com potencial para controlar a contaminação ambiental e infecção animal por A. pleuropneumoniae, representando uma alternativa contra o crescente aumento de resistência bacteriana aos antibióticos.

ABSTRACT: Actinobacilluspleuropneumoniae is the causative agent of swine pleuropneumonia, a contagious respiratory disease associated with high morbidity and economic losses. While antibiotic therapy helps to control the spreading of the pathogen on the farm, resistance to several classes of antibiotics were reported, and treatment can be impaired by the bacterial ability to form biofilms. This increases the need for alternative therapy approaches, including the use of natural compounds with antimicrobial and/or antibiofilm activities. In this research we analyzed, by the broth microdilution method, the inhibitory and bactericidal activities of the essential oils obtained from eighteen Brazilian popular medicinal plants or spices against clinical isolates of Actinobacilluspleuropneumoniae. After that, sub-inhibitory concentrations of active oils were tested for their antibiofilm effects, analyzed by the crystal violet method. Among the eighteen oils tested, eight (extracted from cinnamon, coriander, peppermint, spearmint, thyme, marjoram, eucalyptus, and laurel) presented bacteriostatic and bactericidal activities against all isolates, and subinhibitory concentrations of five of them disrupted up to 80% preformed biofilms, and significantly inhibited biofilm formation. The chemical composition of such oils was assessed by gas chromatography/mass spectrometry (GC/MS) and is presented, indicating that their bactericidal and antibiofilm properties were mostly associated with the presence of monoterpenes and phenylpropanoids. To our knowledge, this is the first report of essential oils with potential to control environmental contamination and animal infection with A. pleuropneumoniae, representing an alternative to increasing levels of antibiotic resistance.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the impact of study methodology and evaluation type on the selection of studies during the presentation of scientific events. METHODS: A prospective, observational, transversal approach was applied to a cohort of studies that were submitted for presentation at the 2021 Brazilian Breast Cancer Symposium. Three forms of criteria (CR) were presented. CR1 was based on six criteria (method, ethics, design, originality, promotion, and social contribution); CR2 graded the studies from 0 to 10 for each study, and CR3 was based on five criteria (presentation, method, originality, scientific knowledge, and social contribution). To evaluate the item correlation, Cronbach’s alpha and factorial analysis were performed. For the evaluation of differences between the tests, we used the Kruskal-Wallis and post-hoc Dunn tests. To determine the differences in the study classifications, we used the Friedman test and Namenyi’s all-pairs comparisons. RESULTS: A total of 122 studies were evaluated. There was also a good correlation with the items concerning criterion 1 (α=0.730) and 3 (α=0.937). Evaluating CR1 methodology, study design and social contribution (p=0.741) represents the main factor and CR3 methodology, and the scientific contribution (p=0.994) represents the main factor. The Kruskal-Wallis test showed differences in the results (p<0.001) for all the criteria that were used [CR1-CR2 (p<0.001), CR1-CR3 (p<0.001), and CR2-CR3 (p=0.004)]. The Friedman test showed differences in the ranking of the studies (p<0.001) for all studies (p<0.01). CONCLUSION: Methodologies that use multiple criteria show good correlation and should be taken into account when ranking the best studies.

Abstract Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this pathology. Despite the prevalence of radiation-induced proctopathy, there is no definitive standardized treatment strategy so far. The first approach can be tried with local agents, such as mesalazine and formalin. For refractory cases, control can usually be achieved with argon plasma coagulation, hyperbaric oxygen, and radiofrequency ablation therapies. Regarding the study of radiation-induced proctopathy, there is a lack of robust studies with large samples and standardized therapies to be compared. There is a lack of double-blinded, randomized controlled studies to determine a definitive standard treatment algorithm.

RESUMO Na verificação de elementos estruturais em situação de incêndio por meio de equações analíticas, e mesmo via modelagem numérica, normalmente são empregados parâmetros e propriedades dos materiais simplificados. Entretanto, os resultados obtidos podem ser bastante sensíveis ao grau de simplificação adotado pelo projetista ou mesmo conforme à escolha de uma ou outra opção de propriedade dos materiais envolvidos. No presente artigo foi apresentado um estudo de sensibilidade considerando a variação das propriedades dos materiais; visando auxiliar a escolha desses parâmetros dentre as diversas opções descritas na literatura. O estudo de sensibilidade foi elaborado para pilares compostos por tubos de aço de seção circular e quadrada, vazio e preenchidos com concreto, e com as propriedades do aço e concreto indicadas pelo Eurocode ou por normas brasileiras para o dimensionamento de estruturas em situação de incêndio. Também foi analisado o comportamento do modelo conforme variações no teor de umidade do concreto e variações da emissividade da superfície de aço exposta ao fogo. O estudo foi realizado em modelo numérico desenvolvido no software ABAQUS e os resultados obtidos demonstram que os valores de 0,7 e 0,8, recomendados na literatura para a emissividade resultante, são conservadores e a alternância entre esses dois valores não altera, significativamente, o campo de temperaturas na seção transversal do elemento estrutural. Já com relação ao teor de umidade do concreto foram verificadas alterações significativas no campo de temperaturas, inclusive na temperatura do tubo de aço, com a alternância deste parâmetro. Com relação às propriedades físicas e mecânicas dos materiais, o estudo de sensibilidade sugere a adoção dos valores obtidos a partir das equações sem simplificações apresentadas no Eurocode e com o valor do calor específico do concreto determinado conforme Eurocode 4.

ABSTRACT For the dimensioning of structural elements in fire situation, simplified equations and parameters are commonly used in analytical equations or numerical models. More complex equations or simplified values can be chosen by the designer for determine materials properties in high temperature in numerical models, however, numerical modeling can be quite sensitive to the variation of some of the physical and mechanical properties. In this paper, the sensitivity of the numerical model in relation to the values according to the level of simplification chosen was evaluated, presenting an analysis in relation to the results found to contribute to the choice of these parameters and presenting the indications found in the literature. In this sense, this work presents a study of sensitivity to the variation of the values of steel and concrete properties, presented in the Eurocode and Brazilian standards, in addition to the moisture content and emissivity of the surface exposed to fire, for the dimensioning, in a fire situation, of steel tube columns, of circular and square section, filled with concrete. The studies were carried out via numerical modeling developed in the software ABAQUS. It was verified that the resulting emissivity values equal to 0.7 or 0.8, recommended in the literature, are conservative, and the choice of either does not bring significant changes in the temperature field obtained for the structural elements under analysis. It was also verified that the concrete moisture content is a relevant aspect for the formation of its temperature field, also affecting, but to a lesser extent, the steel temperature. Regarding the physical and mechanical properties of the materials, this sensitivity study suggests the adoption of the values from the equations presented in Eurocodes, without simplifications, and with the specific heat and thermal conductivity of the concrete, adopted in accordance with the Eurocode 4.

Resumo A verificação da resistência ao fogo de pilares tubulares preenchidos com concreto é necessária, uma vez que há uma drástica redução na resistência do aço e do concreto com a elevação da temperatura. A simulação numérica, com inquestionáveis vantagens econômicas em relação aos ensaios em laboratório, tem grande importância na verificação da resistência e na definição e ajustes de modelos analíticos para uso na prática de projeto. Entretanto, parâmetros intervenientes como o comportamento térmico e mecânico do concreto confinado quando aquecido ou mesmo do chamado “air-gap”, fenômeno inerente a pilares de aço preenchidos com concreto quando aquecidos, ainda carecem de melhor aprofundamento quanto à modelagem numérica. Para tanto, neste trabalho, apresenta-se o desenvolvimento de um modelo numérico no software ABAQUS (Dassault Systemes SIMULIA Corp., 2014), para análise térmico-mecânica de pilares curtos compostos por tubos de aço de seção circular e quadrada, preenchidos com concreto, considerando o efeito do“air-gap”. O fenômeno do “air-gap” é apresentado e discutido em função das possibilidades de implementação no modelo numérico e, por fim, o modelo desenvolvido é validado por meio de resultados experimentais retirados da literatura. Com base nos resultados obtidos, se conclui que o modelo numérico pode ser utilizado para avaliação, ajustes e desenvolvimento de processos simplificados para verificação de pilares mistos em situação de incêndio; sendo recomendada a análise conjunta térmico-mecânica e a utilização do solver explicit como estratégia para minimizar o tempo de processamento. Aimportância da consideração do efeito do “air-gap” foi confirmada e desprezar o seu efeito pode resultar em avaliação superestimada da capacidade resistente do tubo de aço em situação de incêndio.

Abstract The increase in temperature reduces the strength of steel and concrete, in such a way that it is essential to verify concrete-filled steel tube columns in fire situations. Numerical simulations, with lower costs than laboratory tests, have great importance in checking resistance and defining simplified methods for design practice. However, peculiarities of the thermal and mechanical behavior of heated confined concrete and the air-gap effect (a phenomenon inherent to concrete-filled steel columns) must still be better understood. Therefore, this study presents the development of a numerical model performed in the ABAQUS software (Dassault Systemes SIMULIA Corp., 2014) for the thermomechanical analysis of short columns composed of circular and square concrete-filled steel tubes considering the air-gap effect. The air-gap phenomenon is presented and analyzed according to possibilities of implementation to the numerical model and, finally, the proposed numerical model is validated with experimental results presented in the literature. According to the study results, the numerical model can be used to define and adjust simplified methods for verification of composite columns in fire situation. The importance of considering the air-gap effect in numerical modeling was confirmed, taking into account that disregarding its effect may result in overestimated responses of the steel tube resistance in fire situations. Moreover, it was suggested thermomechanical joint analysis and the use of the explicit solver as a strategy to minimize processing time.

Abstract Health professionals working to mitigate the COVID-19 pandemic are one of the main risk groups for the disease, being prioritized for vaccination. Considering this, the aim of this study was to analyze the immune response of these professionals immunized with CoronaVac in the first and second doses. Blood samples were collected after the first and second doses of the vaccine (CoronaVac) and used to investigate hematological and biochemical parameters, analysis of immunoglobulin production, cytokines, and gene expression profile, as well as the identification of subsets of immune cells. Post-first dose immunological phenotypic memory (CD27+) profiles (T CD4+, TCD8+ and CD19+) showed a significant increase, as did Monocyte APCs (CD80+HLA-DR+) in relation to the second dose. The cytokines IL-2, IL-6 and IFN-° showed increased values in relation to the other analyzed cytokines. The Th2/Th17 profile in the second dose was characterized by gene expression analysis. The production of IgM and IgG after vaccination showed statistically significant values in the comparison between doses. CoronaVac showed activation of APCs monocytes, memory response of T and B lymphocytes, with immunoglobulins production. This set of responses is characterized by the Th2/Th17 immunological profile.

RESUMO Objetivo: Compreender os processos de territorialização no cotidiano de vida e trabalho de assentados em Querência do Norte, Paraná. Originalidade/valor: Este trabalho contribui com o contexto das discussões acerca do território e processo de territorialização (Haesbaert, 2011; Raffestin, 1993, 2008; Saquet, 2008) no cotidiano (De Certeau, 2014) de trabalhadores marginalizados pela sociedade de forma geral. Design/metodologia/abordagem: Este artigo de natureza qualitativa foi desenvolvido a partir de dados coletados por meio de oito entrevistas de história de vida com assentados, pré-assentados e moradores de Querência do Norte. Depois de transcritas, as entrevistas passaram por uma análise de narrativas. Resultados: Identificamos que a partir das práticas de trabalho, estudo e reivindicações, os assentados territorializam o espaço e ali passaram a criar suas próprias regras e normas de convivência. Em suas lutas pela terra, torna-se claro que seu local de pertencimento é o campo, justificando a insistência na luta pelo direito à terra para cultivar. O sentimento de pertencimento dos trabalhadores é representado pela luta que os une e os coloca como parte de um movimento maior. Tendo o homem como centro, a construção da territorialidade se faz no cotidiano de luta e trabalho dos assentados e pré-assentados em Querência do Norte.

ABSTRACT Purpose: To understand the processes of territorialization in the daily life and work routine of settlers in Querência do Norte, Paraná, Brazil. Originality/value: This work contributes to the context of discussions on territory and territorialization processes (Haesbaert, 2011; Raffestin, 1993, 2008; Saquet, 2008) in the daily life (De Certeau, 2014) of workers marginalized by society in general. Design/methodology/approach: We developed this qualitative article from data collected through eight life history interviews with settlers, pre-settlers, and residents of Querência do Norte, in the State of Paraná (PR). After transcribing the interviews, they went through an analysis of narratives. Findings: We identify that, through the practices of work, study and claims, the settlers territorialize the space, and there they create their own rules and norms of coexistence. In their struggles for land, it is clear that their place of belonging is the field, justifying the insistence on the struggle for the right to land to cultivate. The sense of belonging of the workers is represented by the struggle that unites them and places them as part of a larger movement. Placing men at the center of the construction of territoriality is accomplished through the daily struggle and work of the settlers and pre-settlers in Querência do Norte (PR).

RESUMO Objetivo: Realizar uma simulação numérica, por meio do Método dos Elementos Finitos (MEF), para obter as tensões de von Mises em arcos Mushroom. Métodos: Foram usados arcos com geometria Mushroom de titânio-molibdênio, com secção transversal 0,017” x 0,025”. Adotou-se valores de tensão de escoamento (σesc) de 1.240 MPa e módulo de elasticidade (E) de 69 GPa. O arco foi modelado por meio do software Autodesk Inventor, e seu desempenho foi simulado utilizando-se o software de elementos finitos Ansys Workbench (Swanson Analysis System, Houston, Pennsylvania, EUA). Para a simulação, foi considerada a análise para grandes deslocamentos. O arco foi conformado em suas extremidades considerando-se planos de 0° e 45°, pré-ativado em 2,5mm e ativado por meio de suas extremidades verticais, separadas 4,0 mm ou 5,0 mm. Resultados: As tensões revelaram um valor máximo de 1.158 MPa na maior parte da alça, aos 5,0 mm de ativação, com exceção de uma área muito pequena, com valor de 1.324 MPa, situada no topo da alça. Conclusões: Os arcos Mushroom são capazes de produzir níveis de tensão situados dentro da região elástica e poderiam ser ativados com segurança até os 5,0 mm de ativação.

ABSTRACT Objective: To perform a numerical simulation using FEM to study the von Mises stresses on Mushroom archwires. Methods: Mushroom archwires made of titanium-molybdenum alloy with 0.017 x 0.025-in cross-section were used in this study. A YS of 1240 MPa and a Young’s modulus of 69 GPa were adopted. The archwire was modeled in Autodesk Inventor software and its behavior was simulated using the finite element code Ansys Workbench (Swanson Analysis Systems, Houston, Pennsylvania, USA). A large displacement simulation was used for non-linear analysis. The archwires were deformed in their extremities with 0° and 45°, and activated by their vertical extremities separated at 4.0 or 5.0 mm. Results: Tensions revealed a maximum of 1158 MPa at the whole part of the loop at 5.0mm of activation, except in a very small area situated at the top of the loop, in which a maximum of 1324 Mpa was found. Conclusions: Mushroom loops are capable to produce tension levels in an elastic range and could be safely activated up to 5.0mm.

RESUMO A expansão da cultura da cana-de-açúcar na região Centro-Sul tem sido predominantemente em solos arenosos com baixo potencial produtivo. Os objetivos deste trabalho foram avaliar a manutenção do palhiço, consórcio da cana com a braquiária e doses de nitrogênio no cultivo da cana em solo arenoso do Paraná. O experimento foi instalado em condições de campo, situado no município de Paranavaí-PR, na unidade da Rede Interinstitucional para o Desenvolvimento do Setor Sucroenergético (Ridesa). O solo foi classificado como sendo um Latossolo Vermelho-amarelo distrófico. Os tratamentos na cana-planta foram constituídos de um fatorial 4x2, sendo quatro doses de nitrogênio (0, 50, 100 e 150 kg ha-1) e cana consorciada e não consorciada com braquiária. Na ocasião da colheita da cana-planta, implementou-se o palhiço como novo fator para ser avaliado na cana-soca. Os tratamentos da cana-soca foram constituídos de um fatorial 4x2x2, sendo quatro doses de nitrogênio (0, 50, 100 e 150 kg ha-1), cana consorciada e não consorciada com braquiária, e uso do palhiço e o não uso do palhiço. A manutenção do palhiço na superfície do solo pode aumentar o desenvolvimento agronômico da cana e, por outro lado, o consórcio de capim braquiária pode reduzir. A cana-de-açúcar foi responsiva às doses de N e, nas maiores doses, compensou a ausência do palhiço e reduziu a competição entre as espécies.

ABSTRACT The expansion of sugarcane cultivation in the Center-South region of Brazil has led to the use of, mainly, areas with low-yielding sandy soils. In this context, the objectives of this study were to evaluate the maintenance of the sugarcane straw, Brachiaria grass intercropping in sugarcane fields and nitrogen fertilization and on sandy soils in the state of Paraná. The field experiment was installed in the Paranavaí-PR city, at a unit of the Interuniversity Network for the Development of the Sugarcane Sector (RIDESA). The soil was classified as Latossolo Vermelho-amarelo distrófico. The treatments in the plant cane stage, consisting of four nitrogen rates (0, 50, 100 and 150 kg ha-1) and monoculture or Brachiaria grass intercropping in sugarcane fields were arranged in a 4x2 factorial design. At plant cane harvest, the effect of unremoved straw was included as a new factor to be evaluated in the ratoon crops. The treatments in the ratoon crops were arranged in a 4x2x2 factorial design, consisting of four nitrogen rates (0, 50, 100 and 150 kg ha-1), monoculture or Brachiaria grass intercropping in sugarcane fields and the presence or removal sugarcane straw. The sugarcane straw on soil surface can increase the agronomic development of sugarcane and, the other hands, Brachiaria grass intercropping in sugarcane fields can reduce. Sugarcane was responsive to N rates and, in the highest rates, compensated the sugarcane straw absence and reduced Brachiaria grass intercropping competition.

ABSTRACT Many industries have a complex manufacturing line, which complicates the planning of their productions. One possible solution to this problem is the optimization of the production line. In this work, mixed integer linear programming models are capable of representing the productive organization of the production line of a hair cosmetics factory, characterized by hybrid flow shop problem. The proposed models can be solved using CPLEX® Optimization Studio for real cases of the studied industrial production line. The objective was the minimization of the production makespan and the completion time. The innovation of this work is the application of the mixed integer linear programming method in complex cases, which are often found in industries and are solved by heuristic methods, simulations, or approximations of analytical methods.

Abstract Objective: The goal of the present study was to compare the myocardial protection obtained with histidine-tryptophan-ketoglutarate (HTK) cardioplegic solution (Custodiol®) and with intermittent hypothermic blood solution. Methods: Two homogenous groups of 25 children with acyanotic congenital heart disease who underwent total correction with mean aortic clamping time of 60 minutes were evaluated in this randomized study. Troponin and creatine kinase-MB curves, vasoactive-inotropic score, and left ventricular function were obtained by echocardiogram in each group. The values were correlated and presented through graphs and tables after adequate statistical treatment. Results: It was observed that values of all the studied variables varied over time, but there was no difference between the groups. Conclusion: We conclude that in patients with acyanotic congenital cardiopathies submitted to total surgical correction, mean aortic clamping time around one hour, and cardiopulmonary bypass with moderate hypothermia, the HTK crystalloid cardioplegic solution offers the same myocardial protection as the cold-blood hyperkalemic cardioplegic solution analyzed, according to the variables considered in our study model.

Abstract Introduction: People carry backpacks of different weight in different positions every day. The effects of backpack wearing under different loads and positions were assessed according to the gait’s spatiotemporal parameters and their variability in young adults. Methods Twenty-one subjects performed trials of 4 min in the conditions: control condition with no backpack; bilateral back load consisting of 10% body weight (BW); bilateral back load of 20% BW (B20); unilateral load of 10% BW; unilateral load with 20% BW (U20); bilateral frontal load with 10% BW; bilateral frontal load with 20% BW. Results Step length (SL) and step frequency (SF) show that frontal conditions differed from others as seen in B20. Gait cycle phases showed an increase in the B20 condition for double stance phase and stance phase, swing phase presented reduction in the B20 condition. There were significant main effects in position for SL, SF, and walk ratio, in load only for stride width. The highest variability of spatiotemporal parameters occurred in the U20 condition. All load conditions with 20% BW showed a greater variability when compared to the 10% BW counterpart. Conclusion We concluded that young adults can cope with up to a 15% BW load under a bilateral back position, but in the frontal position not even a 10% BW load was proven to be a safe limit. 20% BW loads should be avoided in any position. These recommendations may assure increased gait stability, decreased trunk forward lean and decreased muscle activation and fatigue reducing back pain occurrence.

Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil construction area, offering constructive and esthetic advantages. The Eurocode 4 (EN 1994-1-2, 2002) and ABNT NBR 14323:2013 show simple methods for the design of the composite columns under fire situations. Nevertheless, these present limitations in their application. In addition, regarding the determination of the temperature field in the cross section, the Eurocode 4 (EN 1994-1-2, 2002) describes a specific procedure for columns with section profile covered with concrete, but it is neglectful about concrete-filled tubular columns. The goal of this paper is to present a simplified procedure to determine the temperature registered in concrete-filled steel columns and apply the procedure to columns with square section tubes. The temperature distribution was determined by simulations using the computer package ABAQUS (Dessault Systemes Simulia Corp. 2013). After the studies, it has been considered that the procedure described in this paper is an effective alternative for the determination of the field's temperature and for the application of the design of the concrete-filled columns under fire conditions.

The participants answered the HAD scale with 14 questions related to levels of anxiety and depression. The CG had higher scores of depression and anxiety than GT. The results for anxiety (GT = 5.2 ± 2.7, CG = 9.5 ± 4.0) and depression (GT = 4.1 ± 2.6, CG = 7.7 ± 4.0) differed significantly (P<0.05) between groups. Middle-Aged women who participated in a resistance exercise program presented a better mental health as evidenced by a lower levels of depression and anxiety in relation to sedentary counterpartners.

OBJECTIVES: To assess biomechanically different fixations means of the sacroiliac joint with pedicle screws and to compare the traditional head height with reduced ones. METHODS: We used a polyethylene model representing the pelvic ring and simulated a unilateral sacroiliac dislocation. We set up three different constructions: 1) two screws attached to a rod; 2) two rods connected to two small head screws each; and 3) two rods connected to two average headed screws each. We conducted tests in a biomechanical testing and a mechanized processing laboratory. RESULTS: Group 1 supported an average maximum load of 99.70 N. Group 2 supported an average maximum load of 362.46 N. Group 3 endured an average maximum load of 404.15 N. In the assembly with one rod, the resistance decreased as compared with the one with two bars: 72.5 % compared to small-headed screws and 75.3 % to the traditional screw. CONCLUSION: The assembly with a single bar presented inferior results when compared to the double bar assembly. There was no statistical difference in the results between the screws used. Experimental Study.
