title: Rotator cuff syndrome in truck assembly line workers

description: Abstract Objectives To identify biomechanical risk factors for rotator cuff syndrome (RCS) and analyze factors associated with cases found among truck assembly workers. Methods A cross-sectional study was conducted in an automaker of trucks in the metropolitan area of Sao Paulo in 2013. Ergonomics evaluation of workstations was performed using OWAS. Among 79 workers who participated in the study, RCS cases were those who reported pain complaints in the shoulders during the past week and whose RCS´s specific physical evaluation was positive. Results Nine of the 12 workstations analyzed require biomechanics of the upper limbs with lifting above shoulder level. The ergonomic tool indicates the need for immediate corrective action in five workstations. The profile of the participants was as follows: male, mean age of 35 years, average working time in the company of 7.83 years. RCS was found in 17.7% of the participants. The outcome was associated with age and working time in the company. Conclusion Workers who perform this activity can develop RCS. Older employees and those who have worked longer in the company are the groups that should be evaluated more frequently so that early diagnosis can be achieved.

title: Urban Strategic Management, City Marketing, Total Quality Management and local economic development. Methodological approach

description: Abstract Cities have an increasingly important role as generators of economic development. They are dynamic and complex realities that compete with each other to attract resources, funds and talent. Thus, cities need to be able to manage successfully the multiple challenges that condition their competitiveness. Therefore, urban management constitutes a field of study of maximum transcendence. This article claims case study as a methodology of great scientific validity, useful to learn and understand how to implement Urban Strategic Management and its implications in urban competitiveness analyzed from an economic perspective. Firstly, the paper highlights the scientific character of case study as a qualitative methodology. Subsequently, we propose a methodological design to follow in case studies in order to guarantee the validity and reliability of the results. The later section details the execution of this methodology in a specific investigation related to urban management. The results show that urban managers seem to prioritize the development of City Marketing and/or Total Quality Management, and that these practices favor, ultimately, the development of Urban Strategic Management and the improvement of urban competitiveness directly and indirectly.

title: SOIL MICROBIOLOGICAL ACTIVITY AND PRODUCTIVITY OF MAIZE FODDER WITH LEGUMES AND MANURE DOSES

description: ABSTRACT Maize is an important cereal and it is widely consumed in the world, both as food for humans and animals. Nitrogen (N) is a nutrient required in large quantities by maize, but unfortunately, soils are limited in meeting this need. Nodulating legumes can serve as a source of Nitrogen, because they are symbiotically associated with bacteria capable of fixing atmospheric N. Another important source of this nutrient is cattle manure, which is widely used in agriculture. The objective of the present study was to evaluate the effect of using legumes and cattle manure on the production as well as the microbial and biochemical quality of the soil used for maize cultivation. The experiment was conducted using a randomized complete block design, in a sub-subdivided plot scheme [(2x4) +2], two leguminous plants (pigeon pea and macassar bean), four doses of cattle manure (0, 20, 40 and 60 t ha-1) and two controls; one with mineral fertilization and the other cultivated without the use of fertilizers. Treatment using a manure dose of 60t ha-1 and pigeon pea legume, recorded higher dry mass production per plant. The increase in manure doses was directly proportional to the length and weight of the cobs for the two legumes. The enzymatic activities were affected by the different doses and legumes, with greater results being recorded at the 60 t ha-1 dose with the macassar legume. The use of legumes with manure improved maize production as well as the microbiological and biochemical quality of soils.

title: Growth Stress in Peltophorum dubium and its Correlation with the Growth Variables

description: ABSTRACT The exploitation of valuable native timber species in forest restoration projects has emerged as a promising strategy to make restoration financially viable. There are few studies regarding the quality of timber from restoration plantations. The aim of this study was to analyze growth stresses by determining the longitudinal residual strain (LRS) and evaluate their correlation with the growth variables in the species Peltophorum dubium (Spreng.) Taub in a 14-year old restoration plantation. Eighteen individuals were evaluated, determining the following variables: diameter at breast height (DBH), bark thickness, average annual growth in diameter (IMA) and annual periodic growth in diameter (IPA 2012-2015 ). The LRS was determined by the extensometer (CIRAD-Forêt), on DBH height and in the north-south direction of each tree. The LRS average was 0.072 mm, within the range of expected wood values for sawmilling. There was a significant positive correlation between the LRS, DBH and IMA.

title: Reduction of the erosive effects of effluent jets from spillways by contractions in the flow

description: ABSTRACT Flaring Piers and Slit Buckets are structures that can improve the process of energy dissipation and have been implanted in Chinese spillways for at least four decades. These structures basically narrow the passages of the outflow through the spillway, promoting changes in the effluent jets, reducing their erosion potential. However, the literature available on the subject is very limited, and the benefits are disseminated only qualitatively. In order to learn more about how these structures perform, a test program on a hydraulic model was carried out, using a spillway originally designed with a conventional ski jump. The results indicate that there is a correlation between the angle of deflection of the walls that narrow the chute and the depth of the scour hole formed downstream. One of the alternative tests had scour depth 60% smaller than that generated by the spillway without the device, indicating that they can be promising solutions.

title: Soil Microbial Attributes Under Agroforestry Systems in the Cerrado of Minas Gerais

description: ABSTRACT The aim of this study was to evaluate the soil microbiological attributes of two Agroforestry Systems (AFS) in the city of Grão Mogol-MG considering two soil classes (Udox and Aqualf). Three composite samples were collected from the 0-5 cm soil depth layer. Each sample was subsequently divided into five replications to evaluate the carbon of soil microbial biomass (SMB-C), metabolic quotient (qCO2), microbial quotient (qMIC), basal respiration (SBR) and the soil CO2 efflux. The microbiological attributes of the soil were more influenced by the season than by the AFS group. The BMS-C and SBR were higher in the dry season while the CO2 efflux was higher during the rainy season. The similar values of the microbiological attributes between the evaluated systems indicate that AFS are efficient at incorporating carbon and maintaining the soil biological activity similar to that of native vegetation areas.

title: Risk associated with mass movement in the Boa Vista Hill (Vila Velha/Espírito Santo): from territory characterization to the need for public policies

description: Abstract This article aims to understand the vulnerabilization process of a community located on the Boa Vista Hill (city of Vila Velha – State of Espírito Santo) from an interdisciplinary perspective. Methods included a risk perception survey, interviews to collect the history of the occupation, photographic records and local geologic assessment. The scenario shows an occupation influenced by political forces that impelled the population to occupy the area in the 1960s, after the rural exodus that occurred simultaneously to the State’s industrialization. Either by the absence or omission of the public authorities, the rockfall disaster of January 2016 exposed that process, as well as the second-class citizenship of the local population and the urge for measures to reduce the risk of disasters.

title: Analysis of options of production and access ways in underground mines

description: Abstract This article aims to review the issues to be considered in choosing primary access and transportation options for underground mines. The main accesses to underground orebodies are declines or vertical shafts. They serve both as a way to transport ore or waste, and move people, equipment or supplies. In underground mines, the ore transport option significantly affects the productivity and profitability of the company. Then, choice of access is a way to reduce costs and improve production. This study is primarily based on some case studies of Brazilian, South African, Australian and Turkish mines, among others. Literature review shows that the depth at which shaft hoisting becomes a more economically attractive alternative to decline truck haulage is changing from being previously 350 m to present 1000 m, depending on the mining country and cultural underground mine development. For some of them the depth of 1000 m would be the threshold for use of the access by decline. The main criteria in determining access are depth, rate of production and mine life. In South Africa, mines reach depths greater than 3000 m and shaft access is more common. In Australia there are mines that use a ramp (decline) to a depth greater than 1000 m. In Brazil, underground mines are still shallow (depth up to 800 m) and feature short mine life and, most of them have chosen access by decline. Results of this study corroborate the statement that decline is ideal for shallow mines and low production rates and that shaft is for deep mines, high production rate and long mine life.

title: Integration Analysis of Conceptual Design and Stealth-Aerodynamic Characteristics of Combat Aircraft

description: ABSTRACT In order to study stealth strike-fighter, an analysis on stealth-aerodynamic integration and conceptual design is conducted. A conceptual 3-D digital model with internal antiship missiles and air-to-air missiles is designed in CATIA software. Based on the physical optics and equivalent electromagnetic current methods, using the self-programmed RCSAnsys software, the Radar Cross Section (RCS) characteristics and characteristics of scattering intensity distribution of the model are numerically simulated. Based on the turbulence theory of standard k-ε equations, using Fluent software, the pressure, velocity and lift-to-drag characteristics of the conceptual aircraft are numerically simulated. The simulation results show that the stealth and aerodynamic characteristics of the conceptual aircraft can be designed through integration analysis process, which can provide technical support to the design of the advanced operational aircrafts.

title: Factors associated with morphometric brain changes in cognitively normal aging

description: OBJECTIVE: Cognitive impairment is associated with reductions in brain weight and volume. The factors related to morphometric brain changes in cognitively normal aging remain unknown. We aimed to identify which clinical factors are associated with morphometric brain changes in cognitively normal aging. METHODS: A cross-sectional study of 414 subjects, ≥50 years old submitted to clinical assessment and brain autopsy, after informed consent, was carried out at the São Paulo Autopsy Service, Brazil. Data on cognitive and functional evaluations were collected through structured interview applied to the next-of-kin. Brain weight (g) and volume (mL) measurements were obtained and adjusted for head circumference (cm). Associations between brain weight/volume and related factors were obtained through univariate and multivariate analysis. RESULTS: Participants were predominantly male (60.4%), Caucasian (69%), with mean age of 67.1 ± 10.9 years. Mean brain weight was 1219.2 ± 140.9 g, and mean brain volume was 1217.1 ± 152.3 mL. Head circumference was independently associated with low brain weight (p&lt;0.001) and volume (p&lt;0.001). Total and adjusted brain weight and volume decreased in some conditions. Female gender (p&lt;0.001), hypertension (p&lt;0.009), coronary artery disease (p&lt;0.013) and walking assistance (p&lt;0.011) were associated with lower adjusted brain weight while schooling was associated with higher adjusted brain weight (p&lt;0.003). Female gender (p&lt;0.001), age (p&lt;0.001) and hypertension (p&lt;0.011) were associated with low adjusted brain volume. CONCLUSION: Morphometric brain changes occur despite the absence of cognitive impairment and were predominantly associated with age, female gender, mobility impairment and cardiovascular conditions. Schooling may be a protective factor.
