title: Reliability measure of the rib cage deformity by a postural assessment software in patients with adolescent idiopathic scoliosis

description: Abstract Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine that generates changes in the biomechanics of the rib cage. Digital photogrammetry enables the recording of subtle changes and the interrelationship between parts of the human body that are difficult to measure by other means. The aim of this study was to create angles and thoracic distances and to evaluate the interobserver and intraobserver reliability of these measurements using the Software de Avaliação Postural (SAPO) in patients with AIS. This cross-sectional study evaluated 30 individuals aged between 11 and 18 years with AIS. We used SAPO with the thoracic markers in the form of angles (A) and distances (D) with involves structures like acromion, manubrium, xiphoid process, lower angle of the scapula, last false rib, anterior iliac spine process. Two experienced observers (A and B) analyzed the photos and all followed the same routine of analysis. Intraobserver and interobserver reproducibility was assessed by the Bland-Altman plot and intraclass correlation coefficient (ICC), while intraobserver and interobserver reliability was assessed by the T-Test and Wilcoxon's Test. A high repeatability index was obtained among the evaluations, with twelve of the sixteen variables considered as reliable in all statistical tests. The interobserver analyzes presented excellent correlation coefficients (ICC), showing good reliability for six of the sixteen variables proposed. The SAPO method presented good reproducibility and reliability for most of the thoracic markers created, showing that photogrammetry may be a complementary tool in the evaluation of thoracic alterations in patients with AIS.

title: Sustainability Assessment of logistics activities in a dairy: An example of an emerging economy

description: Abstract Paper aims The objective of this paper is to evaluate the economic, social, and environmental impacts of logistics activities of a dairy producer located in Brazil. Originality The main contribution is to apply a quantitative approach to assessing sustainable logistics in the milk supply chain, serving as a basis for future work on this theme. Research method A single case study of a regional producer of dairy products in Brazil is carried out in this research. A sustainable logistics evaluation model was used that quantitatively measures the impact of transportation, storage (including inventory management and material handling activities), packaging, and acquisition activities in the economic, environmental, and social dimensions. Main findings It illustrates the challenge that a Small Medium Enterprise (SME) will have to expand its logistics actions, aiming to generate benefit to the consumer because of actions in the economic, environmental, and social dimensions. Implications for theory and practice This research expands the literature, as it brings together topics such as sustainability, logistics, supply chain, and agribusiness. The baseline is in the case study with quantitative data that allows us to answer the question of how to be sustainable now, rather than waiting for supply chains to do it first so we can discover it.

title: Are there differences between the loading of an anaerobic capacity test and an agility test in basketball players?

description: Abstract The objective of this article was to know players’ needs in the selected tests, to search for differences between categories and to know if there is any relationship between different tests. The sample consists of 2 teams (u-14, u-16, n=24), which were equipped with a WimuR inertial device. The selected tests were 2 agility tests and a lactic anaerobic capacity test. Neuromuscular and kinematic variables were selected. Descriptive analysis, inferential analysis and analysis of correlation among variables were carried out. Once players’ needs are described, there are no significant differences among kinematic variables depending on the sample category. Nonetheless, there is relationship between kinematic and neuromuscular variables of the different tests. It is frequently claimed that capacity tests are those that cause more fatigue in athletes. For this reason, an analysis was carried out comparing a lactic anaerobic capacity test with an agility test in its two versions. The obtained results can facilitate the work and the evaluation time of a physical condition test since results of athletes in a capacity test could be known by performing tests of lesser requirement. In addition, this would avoid players from experiencing a situation of maximum effort and possible injury, also saving training time.

title: Microstructural and Mechanical Properties of Alumina (Al2O3) Matrix Composites Reinforced with SiC from Rice Husk by Spark Plasma Sintering

description: Abstract Alumina (Al2O3) suffers from low fracture toughness and low bending strength which restrict its application in the industry for some advanced components. The incorporation of submicron SiC into Al2O3 matrix improves mechanical properties of the matrix. However, the high cost of SiC has delayed the industrial interest of synthesizing Al2O3-SiC composites. Rice husk, an agricultural waste material, is a potential source of low-cost SiC. Therefore, this study presents a simple approach to synthesizing SiC from locally sourced rice husk and using it to reinforce alumina. Rice husk was pyrolysed in a tube furnace under argon atmosphere at different temperatures (1000 °C – 1500 °C) and reaction times (60 – 120 min). Furthermore, Alumina powder was admixed with 5 – 20 vol% SiC derived from rice husk, and then sintered at temperatures between 1300 °C – 1600 °C by spark plasma sintering. Maximum yield of SiC was obtained from rice husk at 1500 °C and 120 min. Materials with theoretical densities higher than 95% were achieved for the sintered composites. The hardness of sintered composites reached a maximum of 20.2±1.4 GPa, while a maximum of 4.7±.7 MPa.m0.5 was obtained for the fracture toughness.

title: Effect of small-sided games with manipulation of small targets on the perceived exertion and tactical and technical performance of college soccer players

description: Abstract The purpose of this study was to compare the tactical and technical performance and perceived exertion of college soccer players in small-sided games through the manipulation of small targets. Twenty players divided into four teams, played 5x5 games (25x20 m) with one and two small targets on different days. Games were divided into three four-minute times, with two-minute intervals between bouts. Perceived exertion and technical-tactical variables were evaluated using Ball Transmission Speed (ball received/ball contacts) and Team Sport Assessment Procedure (TSAP). TSAP generates performance indicators, such as: efficiency index, performance score, volume of play and ball attack. They are related to the actions of balls conquered, passes and finalizations. For statistical analysis, paired t test and Cohen’s d effect size were performed to compare the two game configurations. Larger number of balls conquered with small target was verified (p&lt;0.05; d=1.32), generating higher efficiency index and performance score. It was concluded that the perceived exertion is similar with one and two small targets and players recover more balls with only one small target. Through thisinformation, coaches can better handle this type of constraints according to the purpose of the training session.

title: Evaluation of training on brief interventions for teachers: health contributions

description: ABSTRACT Objectives: to evaluate the impact of training on brief interventions for use of substances on the attitudes; and, face validity and internal consistency of Brazilian versions of the Drug and Drug Problems Perceptions Questionnaire (DDPPQ-br) and the Short Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ) for use among teachers. Methods: methodological (N=122) and quasi-experimental study (n=27). A sociodemographic questionnaire, the DDPPQ-br and the SAAPPQ were applied before and three months after the training. For analysis, were applied the Mann-Whitney and Wilcoxon tests. Results: the DDPQ-br and SAAPPQ were considered valid by experts. The training improved teachers’ attitudes towards accountability on the approach to substance use at schools and on the readiness to perform this role. In relation to drugs, it increased the perception of support. Conclusions: teachers’ training can improve their attitudes and strengthen the school in the function of preventing substance-related harm.

title: How context influences the tactical-technical behavior of learners: the case of volleyball

description: Abstract This study compared the tactical-technical behavior between two distinct situations of reduced volleyball games. The sample consisted of 12 games played by doubles, 6 of which were played in 3.0m x 3.0m (SIT1) and 6 of 2.0m x 4.5m (SIT2) courts. Thus, the behavior of 12 participants, with mean age of 16.7 ± 1.5 years and 3.2 ± 1.2 years of practice, was compared. The results showed that at reception, better results were obtained in adjustment and decision making in SIT2, whereas in SIT1, efficiency was higher; in setting, it was observed that SIT2 presented better results in technical performance, adjustment and efficiency, whereas in SIT1, efficiency was higher; in SIT2, attack, better results were observed in adjustment and decision-making. It was concluded that environmental restrictions influence the behaviors of learners, showing that different ecological contexts provide actions inherent to the specific game environment.

title: Strong accelerator and concavity of the consumption function in neokaleckian models: rediscussing the wage-led growth

description: Abstract This essay proposes an alternative for generalization, under certain conditions, of the concept of strong accelerator, in the sense given by Bhaduri and Marglin (1988 and 1990) model, using a concave consumption function. Based on this, it demonstrates that the possibility of a wage-led growth becomes very probable and no more an eventual case. Symmetrically, it makes improbable the possibility of occurrence of profit squeeze. The text also analyses critically the Bhaduri and Marglin canonical model, presenting questions about its clarity as a source of criticism of a range of neokaleckians growth models that have been published previously.

title: Towards a contribution to sustainable management of a dairy supply chain

description: Abstract Paper aims The paper proposes an enhancement to a focal company in the dairy supply chain, in order to support sustainable performance. Originality The authors conclude that previous life cycle assessment (LCA) studies did not recommend for dairy supply chain or use this approach to assess the environmental impacts in this chain. Research method A cradle-to-gate attributional life cycle assessment (LCA) study performed in a focal company and considering its transport and processing stages, and three scenarios were proposed as suitable. Main findings The impacts derive from energy use and transportation of feedstocks, and the use of cleaning products and certain types of packaging materials. A decrease of 46.5% of the impact in the photochemical oxidant formation category was achieved. Implications for theory and practice The results can identify the different impacts throughout the dairy chain associated with the main product’s life cycle, and the possibility of mitigating them.

title: Boundaries in metagenomic screenings using lacZα-based vectors

description: Abstract Metagenomics approaches have been of high relevance for providing enzymes used in diverse industrial applications. In the current study, we have focused on the prospection of protease and glycosyl hydrolase activities from a soil sample by using the lacZα -based plasmid pSEVA232. For this, we used a functional screen based on skimmed milk agar and a pH indicator dye for detection of both enzymes, as previously reported in literature. Although we effectively identified positive clones in the screenings, subsequent experiments revealed that this phenotype was not because of the hydrolytic activity encoded in the metagenomic fragments, but rather due to the insertion of small metagenomic DNA fragments in frame within the coding region of the lacZ gene present in the original vector. Analyses of the thermodynamic stability of mRNA secondary structures indicated that recovering of positive clones was probably due to higher expression levels of the chimeric lacZα-genes in respect to the original from empty vector. We concluded that this method has a higher tendency for recovery false positive clones, when used in combination with a lacZα-based vector. As these vectors are massively used in functional metagenomic screenings, we highlight the importance of reporting boundaries in established metagenomic screenings methodologies.

title: Association between Genetic Polymorphisms in RANK, RANKL and OPG and Peri-Implant Diseases in Patients from the Amazon Region

description: Abstract The present study evaluated polymorphisms in RANK, RANKL and OPG-encoding genes to assess whether they are associated with mucositis and peri-implantitis in a population from the Brazilian Amazon region. One hundred and fourteen patients with dental implants were included in the study. After clinical and radiographic examination, the sample was categorized into 4 groups, according to the peri-implant status: Healthy (n=71), Mucositis (n=30), Peri-implantitis (n=13) and Diseased (Mucositis + Peri-implantitis, n=43). Genomic DNA was extracted from buccal cells from saliva, and the genetic polymorphism in osteoprotegerin (OPG), Kappa nuclear factor activator receptor (RANKL) and nuclear kappa factor activator receptor (RANK) were genotyped by the real time PCR. Univariate and multivariate statistical analyses were performed to compare clinical variables among groups and to evaluate genotypes and alleles distributions and the established alpha was 5%. Age, peri-implant biotype, diabetes and presence of peri-implant biofilm were associated with mucositis (p&lt;0.05) and peri-implantitis (p&lt;0.05). Smoking, alcoholism, and periodontal biofilms were also associated with the presence of peri-implantitis (p&lt;0.05). Univariate and multivariate analysis did not demonstrate an association of peri-implantitis or mucositis with any genetic polymorphism in RANK (rs3826620), RANKL (rs9594738) and OPG (rs2073618) (p&gt;0.05). The studied genetic polymorphism in RANK, RANKL and OPG were not associated with mucositis and peri-implantitis in a Brazilian population from the Amazon region.
