title: Choreographies on the restricted three-body problem

description: Abstract The three-body problem deals with point objects interacting mutually through Newton's gravitational force. For more than three centuries, the study of this type of system has led to the development and improvement of several mathematical techniques, both analytical and numerical, for the understanding of problems involving dynamical systems. This paper discusses some of these results applied to the restricted three-body problem formulated from Newton's second law and the law of universal gravitation. In particular, the behavior and stability of two important types of periodic solutions of this problem were studied: L. Euler's straight-line alignment and C. Moore's figure-eight choreography. Mathematica software was used to solve the dynamical system and to generate the images of movement of the bodies, as well as to calculate the set of Lyapunov exponents associated with each solution. Despite the inherently chaotic character of the three-body problem observed in the Lyapunov exponents, the figure-eight solution is linearly stable, as discussed in C. Simó's works.

title: Neuroscience: unveiling the brain of Saimiri collinsi (Squirrel Monkey)

description: Abstract Behavioral intelligence among non-human primates is a somewhat puzzling area to study, since it is closely linked to the morphology of the central nervous system. However, this morphology is still unknown to science in the case of Saimiri collinsi. As a means of assisting future studies on the social behavior of this species, we analyzed the brains of six adult females from the National Primate Center / Pará, which were sent to the Animal Morphological Research Laboratory at the Federal Rural University of Amazônia after death by natural causes. The animals were fixed in formaldehyde solution (10%) and dissected. The brains were covered externally by the dura mater, with long cerebral hemispheres, although there was a complete absence of gyri. The internal structures which form a part of the telencephalon, diencephalon, midbrain, hindbrain and myelencephalon were identified, with the exception of the mammillary bodies. This condition, when linked to the lissencephaly found in these individuals raises questions about the real learning abilities of this species.

title: Emancipatory workshops as a worker’s health intervention

description: Abstract This essay presents emancipatory workshops as a proposal for worker’s health intervention aimed at health personnel. The workshops have Historical and Dialectical Materialism as a theoretical methodological reference. They are based on the concept of work as a central category of social relations analysis, and on the theories of social determination of health and of emancipatory education. The emancipatory workshop is strategic to promote a critical analysis of work processes and the proposition to overcome repetitive practices that characterize the health production process. Coherently to the theoretical reference, the workshop consists of an educational process that adopts dialogic strategies, which allow the clear exposition of the essence for the formulation of new syntheses of the phenomena under discussion. New knowledge and practices can only be achieved by radical criticism to the health production process and, ultimately, to capitalism.

title: One-eye-set sugarcane susceptibility to weed interference

description: Abstract The new technology of sugarcane planting, known as one-eye-set seedlings, offer a high standard of plant health and vegetative vigor. However, there are no reports in the literature that evaluate the weed competition with one-eye-set sugarcane seedlings, and the periods in which weed communities need to be controlled in this system. Two interference experiments were conducted in field conditions. The first experiment determined the periods of weed interference of an infesting community predominated by Ipomoea hederifolia and Merremia aegyptia in sugarcane. In the second experiment, these same species competed with plants of the same sugarcane cultivar. Productivity and qualitative aspects of production were evaluated. The critical period of interference prevention in one-eye-set sugarcane system was 103 days, with weed community interference starting at 35 days and lasting until 138 days after planting. Weed coexistence during the entire sugarcane cycle reduced productivity by 60% and affected qualitative characteristics such as the total reducing sugars. Both species affected the vegetative development of the crop, mainly the tillering. I. hederifolia plants developed ahead of the M. aegyptia plants but in late evaluations the interference caused by M. aegyptia (77%) was greater (P&lt;0.01) than that caused by I. hederifolia (72%).

title: Yield analysis of Physalis ixocarpa Brot. ex Hornem varieties under greenhouse and field conditions

description: ABSTRACT: Physalis ixocarpa (husk tomato) is traditionally cultivated in Mexico, and nowadays the yield is low. In this study, four cultivars of husk tomato were evaluated, under greenhouse and field conditions. It was carried out a split-plot experimental design in a 4x2 factorial arrangement. The large plot was the growth conditions and the small plot was the variety. The microclimate, soil and yield variables were recorded. In the field, the Integrated Photosynthetic Active Radiation (IPAR) was higher 12mol m-2 d-1 than in the greenhouse. The average temperature was slightly higher 1.18°C in the greenhouse and the average relative humidity was slightly higher 0.89% in the field. Plants grown in the greenhouse had lower negative values for the matric potential of the soil. Water consumption and water use efficiency were 10.31 and 53.43% higher in the greenhouse that in the field, respectively. The number of fruits and yield increased significantly in all varieties grown under greenhouse conditions.

title: PROGNOSTIC FACTORS IN PATIENTS WITH APPENDICULAR MYXOFIBROSARCOMA

description: ABSTRACT Objective: Myxofibrosarcoma (MFS) is a common soft tissue sarcoma (STS) that affects the extremities in elderly patients. The objective was to analyze the prognostic factors and outcomes of patients with MFS treated at a single institution. Methods: We retrospectively reviewed the records of 75 patients with MFS. We compared age, sex, tumor size and location, grade and stage of the disease. Median age was 49.7 years (range, 1 to 88 y). Location: upper extremity (25.4%), lower extremity (66.6%) and pelvis (8%). Patients had high-grade tumors in 46.7% of the reports. Margins were negative in 76% of the cases. Bivariate Cox regression analysis was used to determine associations between clinical and treatment factors with local recurrence (LR). Results: Median follow-up time was 30.7 months (range, 1.8 to 383.8 m). We found 26.7% of LR. Distant metastasis (DM) was reported in 27 (36%) patients. Lung was the most common site of DM, reported in 92.6% of patients. Overall survival (OS) with metastasis was 21.2 months (range, 4.8 to 114.8 m). Predictors of OS were grade, LR (hazard ratio [HR] 5.13, 95% confidence interval, 2.15-12.24, P &lt;0.001), and DM (HR 540.97, 95% confidence interval, 5.04-58112.03, P&lt; 0.001). Conclusions: Tumor grade, LR, positive margins and DM were significant predictors of poor OS prognosis. Level of Evidence IV, Case Series.

title: Recruitment and profile of Brazilian higher public administrators in economic and social areas from 1994 to 2012

description: Abstract This article analyzes the profile of the public managers of four ministries: Finance and Planning, representing the economic area, and Health and Education, as examples of the social area. Based on empirical data, a comparison of the profile of the occupants of these senior positions from 1995 to 2012 is proposed. The research demonstrates the specificities of the recruitment pattern in these two areas of the bureaucratic field and shows that the public leaders of the economic area come from the most favored social sectors, present a more technical pattern and are less engaged in political, social and union matters. However, they are not intellectually superior in terms of qualifications. The data allow to discuss Bourdieu`s theses on the elites of the bureaucratic field and help to demonstrate the myths about the greater academic qualification of the bureaucratic sectors of the economic and financial areas.

title: Time representation ontology in the context of performance measurement indicators

description: ABSTRACT Performance measurement indicators are widely used by organizations in order to assess, measure and classify organizational performance. As part of performance measurement systems, indicators are often shared or compared to different internal sectors of the organization, or even with other companies. However, some indicators are associated with vagueness and imprecision. In these cases, literature related to time representation can clarify the need for the semantic representation of indicators. This work seeks to analyse the studies available, selected after bibliometric review, on the semantic representation of time through ontologies. The purpose of this is to identify a knowledge model which best served the purpose of representing time in the performance indicators’ context. After applying the METHONTOLOGY methodology, it was concluded that the most suitable option is the SWRL Temporal Ontology, due to its ability to represent fine levels of granularity for points of time.

title: Submerged Friction Stir Welding of 6061-T6 Aluminium Alloy under Different Water Heads

description: The aim of this paper is to determine the feasibility of submerged friction stir welding of 6061-T6 aluminium alloy on different water heads through macrostructuralanalysis.In this work, aluminium 6061-T6 alloy was friction stir welded under normal and submerged conditions at different rotational speeds of 400 rpm, 800 rpm, 1200 rpm, 1600 rpm. The water head was varied from 10 to 30 mm in the case of thesubmerged friction stir welding process. In both normal and submerged friction stir welding processes, a welding speed of 45 mm/min, a normal load of 30 kN, tool tilt angle of 2˚, depth of tool penetration and tool geometry were kept constant. Torque is measured during the welding process, and power (kW) is calculated after the welding process. The macrostructural analysis was carried out for locating defect formation and identifying the feasible working range of process parameters of the welded aluminium 6061-T6 alloy. The mechanical properties such as ultimate tensile strength and microhardness of submerged friction stir welded of 6061 aluminium alloys were investigated.Scanning Electron Microscope (SEM) metallography was used for comparing the microstructure of the parent material, friction stir welded and submerged stir welded samples.

title: ARTHROSCOPIC LATARJET TECHNIQUE COMBINED WITH ENDOBUTTONS: FUNCTIONAL OUTCOMES IN 26 CASES

description: ABSTRACT Objective: The cause of anterior shoulder instability is not fully understood and surgical management remains controversial. The objective of this study was to evaluate the results of patients undergoing arthroscopic Latarjet procedure with endobuttons. Methods: A retrospective study of 26 patients undergoing arthroscopic Latarjet procedure with endobuttons to treat anterior shoulder instability. Patients with previous glenohumeral instability, failure of Bankart procedure or Instability Severity Index Score (ISIS) greater than or equal to 6, were included. Patients were assessed by: DASH, UCLA, Rowe, Visual Analog Scale (VAS) of pain and Short-Form 36 (SF36) scores. Correct position and consolidation of the graft were evaluated. Results: Mean age was 31.5 years (16 to 46). Preoperative duration of symptoms was 1.7 years (1 month to 10 years). Mean follow-up was 14.3 (6 to 24) months. Mean postoperative scores were: 10 points in DASH; 1.6 in VAS, where 23 (88%) patients experienced mild pain and 3 (12%) moderate pain; 89 in Rowe; 32 in UCLA and 78 in SF-36. Positioning of the graft was correct in 25 (96%) cases, and was consolidated in 23 (88%). We had two cases of graft fracture (7%) and postoperative migration (7%). Conclusion: Surgical treatment using arthroscopic Latarjet with endobuttons is safe and effective, producing good functional outcomes in patients. Level of Evidence IV, Case Series.
