title: Trends in the number of traffic accident victims on Brazil’s federal highways before and after the start of the Decade of Action for Road Safety

description: Abstract: This study aimed to analyze the trend in the number of fatalities, severe injuries, and minor injuries from traffic accidents on Brazil’s federal highways according to the country’s major geographic regions before and after the start of the Decade of Action for Road Safety (DARS). This was an interrupted time series study of data on accidents with fatal or injured victims provided by the Brazilian Federal Highway Police from 2007 to 2017. The Prais-Winsten method was used to calculate the monthly percentage change (MPC) in the number of fatalities, severe injuries, and minor injuries. Before the DARS, there was an upward monthly trend in the number of fatalities in these accidents in the country as a whole (MPC 0.71%) and in all five regions, especially in the South (MPC 1.01%) and Central-West (MPC 0.84%). There was an inverse trend after the start of the DARS, with a significant decrease in Brazil as a whole (MPC -1.24%) and in the major geographic regions. For each person that dies in an accident on a federal highway, at least 12 others suffer non-fatal injuries. There was an upward trend in the number of victims with severe injuries (MPC 0.53%) and minor injuries (MPC 0.8%) in Brazil and in the major geographic regions in the period prior to the DARS. After the start of the DARS, there was a significant downward trend in the absolute frequencies of these outcomes at the national and regional levels. In conclusion, before the DARS, there was an upward monthly trend in the number of fatal and injured victims of traffic accidents on Brazil’s federal highways. After the start of the DARS, in 2011, there was an inverse trend, namely a decline in these outcomes in the country.

title: Management and legacy of the Brazil 2014 Fifa World Cup during its candidacy bid

description: Abstract Aim: Sporting mega-event organization requires developing strategies to maximize the chance of success. For the Brazil 2014 Fifa World Cup, it was not different. The action started long before the opening match on 06/12/2014. The issue we seek to investigate is: How did the 2014 Fifa World Cup’s management as a sporting mega-event develop during the pre-event phase? The general objective was to identify and analyze management-related peculiarities of the 2014 Fifa World Cup’s management during the pre-event period. The operational objectives were: (i) To identify the organizational structure set up to manage the 2014 Fifa World Cup; (ii) reveal the candidacy process; (iii) find out the initial budgets/investments planned for the 2014 Fifa World Cup; (iv) examine the management difficulties that happened during the pre-event period; and (v) detect the legacy left by said phase. Method: primary data was collected through an elite interview conceded by ex-Minister of Sports Orlando Silva and secondary data was obtained through bibliographical and documental research techniques. The interview was evaluated through content analysis. The analysis and discussion were categorized as follows: organizational structure, candidacy process, management, and legacy. The results show legacy was obtained in the pre-event phase due to the knowledge generated during the candidacy process. They also show a strengthening of Brazil’s image as a mega-event organizer. Some difficulties include no integration between organizers, delay in defining host-cities and construction, no initial budgets and no transparency in the bid’s initial publishing.

title: Increasing feed allowance in low-fish meal diets allows for a reduction in dietary methionine for juvenile Litopenaeus vannamei raised in green-water tanks

description: ABSTRACT A 10-week study was conducted to evaluate the effect of feed allowance and graded levels of dietary methionine (Met) on growth performance of Litopenaeus vannamei. Juvenile shrimp of 1.83±0.14 g were stocked in 42 outdoor green-water tanks of 1 m3 under 120 shrimp m−2. Animals were fed under two feed allowances, regular and 30% in excess. Five diets with 30 g kg−1 fishmeal were designed to contain 318±2 g kg−1 crude protein and a minimum amount of protein-bound Met. To achieve graded levels of dietary Met, a control diet with 4.6 g kg−1 Met or 8.9 g kg−1 methionine + cysteine (M+C) was supplemented with 1.2, 2.2, 3.2, and 4.2 g kg−1 of DL-methionyl-DL-methionine to result in total dietary Met of 5.6, 6.9, 7.9, and 9.2 g kg−1 (10.0, 11.2, 12.1, and 13.5 g kg−1 M+C, respectively). A final survival of 86.5±3.6% was reached with no significant influence from feed allowance or dietary Met. Feed inputs significantly affected apparent feed intake, weekly shrimp growth, final body weight (BW), and gained yield. Larger meals and a higher dietary Met had no impact on feed conversion ratio. There was a significant interaction between feed allowance and Met over shrimp BW. By feeding animals in excess, BW was enhanced at 6.9 g kg−1 Met. A dietary Met of 7.9 g kg−1 was required to achieve a maximum BW under a regular feed allowance. Thus, shrimp required less amounts of dietary Met to maximize BW when higher feed inputs were delivered. Our findings demonstrate a sparing effect of dietary Met for L. vannamei when a higher feed allowance is adopted. Shrimp farmers should consider adjusting feed allowance to dietary Met to maximize shrimp growth performance and yield.

title: Community structure of invertebrate fauna in Central Chilean Rivers

description: Abstract Aim River systems of Central Chile are short, steep and fast flowing. They are characterized by discharge regimes dominated by rainfall and snowmelt. Invertebrate fauna is highly endemic. This study aimed to describe the community structure of invertebrate in eight river systems in Central Chile (33-39°S) using species co-occurrence and niche sharing null models. Methods Invertebrate samples were collected from Central Chilean rivers (33-39°S), data were analyzed co-occurrence species and niche sharing null models for determine potential structuring patterns. Results The results revealed the presence of non-structured patterns in co-occurrence considering each site as well as all sites, that is most probably an effect of presence of many repeated species in the studied sites. Furthermore, we found the existence of niche overlap due to interspecific competition at each site and among all sites. The results obtained from these river systems corroborate observations from Chilean Patagonian Rivers. Conclusion This study contributes to understanding of biogeographical and ecological patterns of invertebrate communities in central Chilean Rivers and provide foundations for more complex ecological studies.

title: Food environment, income and obesity: a multilevel analysis of a reality of women in Southern Brazil

description: The objective of this study was to explore relationships between the neighborhood food environment and obesity in urban women living in São Leopoldo, Rio Grande do Sul State, Brazil. A cross-sectional survey was carried out. This study was conducted with 1,096 women. Structured interviews were conducted using a standard pre-tested questionnaire. Obesity was defined as body mass index (BMI) ≥ 30kg/m2. Circular buffers of 400m in radius were created based on the centroid of the women’s houses who participated, in the 45 census tracts inhabited by them. Neighborhood food establishments were identified through systematic survey of all streets in the study areas and geographical coordinates of shops were collected. Establishments were evaluated using the NEMS tool. The prevalence of obesity was 33% among the women participants. After adjusting for individual variables, supermarkets and healthy food establishments were positively associated with obesity, PR = 1.05 (95%CI: 1.01-1.10), PR = 1.02 (95%CI: 1.00-1.04), respectively, while mean buffer income was negatively associated, PR = 0.64 (95%CI: 0.49-0.83). Neighborhood food environment factors were associated with obesity even after controlled for individual variables, as socioeconomic variables, behavioral and food purchase.

title: Kasugamycin on Leifsonia xyli subsp. xyli in the in vitro culture of sugarcane

description: ABSTRACT: One of the significant obstacles to the growth of sugarcane production is the infection by phytopathogens, mainly by the bacterium Leifsonia xyli subsp. xyli (Lxx) causal agent of Ratoon stunting disease. Thus, this research aimed to evaluate the effects of kasugamycin on the in vitro growth of sugarcane, as well as its effect on the bacterium Lxx. Explants of strain SP791011 from sugarcane were inoculated in MS culture medium supplemented with the antimicrobial kasugamycin at concentrations of 0.00; 0.87; 1.08; 1.74 and 3.48 mL.L-1, where they remained for 30 days. After this period, the survival rate, shoot number per explant, height of the explants, phytomass, dry phytomass and phytosanitary were evaluated based on the presence of genomic DNA of Lxx. It was verified that the culture in kasugamycin influenced the morphological variables negatively; nevertheless, the antimicrobial did not demonstrate phytotoxicity to the plants. All treatments tested in this experiment were diagnosed as positive, with DNA amplification for Lxx, despite it was observed a reduction in bacterial load, suggesting that kasugamycin at higher doses can be evaluated as an attempt to eliminate the bacterium in the in vitro cultivation of sugarcane.

title: Diversity of springtails (Collembola) in agricultural and forest systems in Southern Santa Catarina

description: Abstract: The aim of this study was to evaluate the influence of soil use on the morphological diversity of springtails and to verify the relationship of these organisms with soil physical, chemical, and microbiological properties. Samples were collected in the Southern region of Santa Catarina, involving three municipalities: Orleans, Lauro Müller, and Siderópolis, in the land use systems (LUS) of native forest (NF), Eucalyptus plantation (EP), pasture (PA), integrated crop-livestock (ICL), and no-tillage (NT). Soil samples to determine edaphic properties and pitfall traps were collected in winter and summer, in the same areas. The collected springtails were counted and morphotyped and the data were analyzed through abundance, Shannon-Wiener diversity (H') and Margalef index, Simpson dominance index (D), Pielou evenness index (J), morphotype richness, and Principal Components Analysis (PCA). Springtails morphotypes were influenced by the management conditions of each system, especially the impact of LUS on these organisms depends on the intensity of the forest/agricultural practices used, including crop rotation and soil preparation.

title: Optimized design of RC deep beams based on performance metrics applied to strut and tie model and in-plane stress conditions

description: Abstract Deep beams do not behave according to classical beam theory. The nonlinearity of strain distribution within these elements requires application of strut and tie models (STM) or other alternatives to evaluate the complex stress field. Although the design of these elements is a common task for structural engineers, limited research is found on assessing effectiveness of the results. The purpose of this work is to compare, in a systematic approach, different design solutions for a deep beam using selected performance metrics which are strain energy, reinforcement ratio, maximum load, structural efficiency, safety factor and cracking behavior. A deep beam (2.85 m of height, 4.20 m of length and 0.2 m of thickness) with a square opening (0.7 m x 0.7 m) close to one of the supports was subjected to a uniform loading at the top surface while resting on supports at both ends. A simplified finite element model (FEM) of this beam was developed simulating concrete with elastic linear stress-strain behavior and disregarding steel reinforcements. This model allowed determination of elastic stress fields necessary to subsequent analyses. Four STM were then developed, supposing the total load respectively represented by one (STM-1), two (STM-2), four (STM-4) or eight (STM-8) concentrated loads equally spaced along the top of the beam. Additionally, an in-plane stress field method (SFM) was applied to the design of the same beam subjected to uniform loading on the top surface. After design and detailing of the reinforcement for each situation, nonlinear FEMs were used to predict the ultimate conditions. The strain energy reduced significantly comparing results from STM-1 to STM-2 and subsequently to STM-4 and remained at a low level in STM-8 and SFM. The reinforcement ratio reduced systematically from STM-1 to STM-8, was minimum with the SFM and the same behavior was followed by maximum load. The structural efficiency (maximum load/reinforcement ratio) increased from STM-1 to STM-8, with maximum efficiency at STM-8 and was slightly below with SFM. The safety factor reduced systematically from STM-1 to STM-8 and was slightly lower with SFM, but in all cases was above acceptable limits found in design codes.
