Background: Despite of the widepread use of Pilates in Physical Therapy, there are few studies that have assessed the muscle electrical activation during Pilates exercises. Objective: Verify the influence of different spring adjustments and individual positions on the electrical activation of multifidus (MU) and oblique external (OE) muscles during hip flexion-extension (HFE) exercise on the Cadillac. Methods: Eight women practicing Pilates exercises for at least six months performed 10 repetitions of HFE in the following situations: Lower Spring, spring fixed at 30 cm in relation to level which the individuals were positioned. Higher Spring, spring fixed at 90 cm in relation to level which the individuals were positioned. Near Position, distance of 10 cm from the fixed spring. Distant Position, distance of 30 cm from the fixed spring. Kinematic and eletromyographic data (EMG) were collected simultaneously and the MU and OE muscles were monitored. Each movement of HFE was splitted in two phases (extension and flexion). The EMG signal was calculated and normalized using the maximal voluntary contraction (MVC). The Wilcoxon test was used to investigate differences between the situations (p≤0.05). Results: MU muscle presented muscle activation values ranging from 10 to 20% MVC, and the highest muscle activation in the lower spring and in the near position. OE muscles presented muscle activation values ranging from 20 to 45% MVC, and the highest values in the higher spring and in the distant position. Conclusion: MU and OE muscles presented a distinct electrical activation during different available spring adjustments and individual positions. © Revista Brasileira de Fisioterapia.

Prescribed fire is a frequently applied land-management tool for the preservation and maintenance of southern pine woodlands. Many avian species benefit from the use of prescribed fire in pine woodlands; however, the effect fire has on nesting site characteristics is not well understood for many disturbance-dependent species. We located nests of Bachman's Sparrows (Peucaea aestivalis) in mature longleaf pine (Pinus palustris) forests managed using frequent prescribed fires (return intervals ≤2 years). Vegetation characteristics were measured at each nest (n = 37), within a 0.04-ha area immediately adjacent to nests, and at different time intervals following burns within a larger 20-ha area surrounding nests. We examined vegetation characteristics within the 20-ha area 2, 6, 12, and 18 months after prescribed burns to compare post-fire plant succession with site characteristics associated with nest sites. Nest sites had lower amounts of grass standing crop, grass ground cover, and higher amounts of woody vegetation than found in the 0.04-ha area immediately surrounding nests. Vegetation structure at nests sites was similar to the structure measured across the 20-ha area <6 months following burns, but vegetation structure at ground level began to deviate ≥6 months after fires such that ≥50% of the values differed from the values recorded at nest sites. Results point to the importance of open vegetation structure at ground level and the need for frequent burning to maintain appropriate nesting habitat. Vegetation characteristics associated with nest sites appear to be highly ephemeral and tightly linked to conditions at ground level. As such, suitable nest sites likely represent a subset of areas occupied by singing males. © 2013 by the Wilson Ornithological Society.

Neoseiulus HUGHES, 1948 is currently one of the largest genus of Phytoseiidae Berlese. Neoseiulus demitei sp. nov., a new species of phytoseiid mite from Rio Grande do Sul State, Brazil, is illustrated and described based on specimens collected on Tibouchina sp. (Melastomataceae) plants. This new species differs from others by having most of propodossomal setae reaching the base of nearby setae and a constriction of ventrianal shield at level of preanal pores. Nevertheless, this new species is the first of the species subgroup kennetti described from Brazil. A key of Neoseiulus species reported in Brazil is also included.

Natural rubber latex was submitted to epoxidation reaction to establish the best reaction conditions without the occurrence of side reactions, which promote coagulation of the latex and development of an agglomerate of rubber. Epoxy groups were produced by in situ epoxidation with formic acid and hydrogen peroxide. The samples were characterized qualitatively by Fourier Transform Infrared (FTIR) analysis and the degree of modification determined by Hydrogen Nuclear Magnetic Resonance Spectroscopy (1H-NMR) analysis. A linear increase in the glass transition temperature (Tg) was observed. The results show that the epoxidation of natural rubber latex is possible and depends on the reaction conditions.

In order to describe adequacy of weight gain during pregnancy and its association with pre-pregnancy nutritional status and other factors, a cohort study of pregnant women enrolled at 16-36 weeks of gestation and followed up until delivery was carried out in prenatal care in primary care services in Rio Grande do Sul State, Brazil. Maternal weight was recorded at each prenatal care visit. Weight gain was classified as "adequate," "insufficient" or "excessive" (Institute of Medicine). Poisson regression was used to measure the associations. The sample was comprised of 667 women, and insufficient and excessive weight gain incidences were 25.8% and 44.8%, respectively. Overweight and obese before pregnancy had a significant increased risk of excessive weight gain in pregnancy (RR: 1.75; 95%CI: 1.48-2.07, RR: 1.55; 95%CI: 1.23-1.96, respectively). Women with fewer than six prenatal visits had a 52% increased risk for weight gain below recommended values. Although insufficient weight gain may still be a public health problem, excessive gain is becoming a concern that needs immediate attention in prenatal care.

Respective literatures on sustainable business models (SBMs) and the bottom of the pyramid (BOP) share the assumption that organizations can contribute to value creation for both business and society. The premise of a win-win solution for multiple stakeholders relies mostly on market-oriented solutions, giving little attention to the role that government programs and regulations may have in promoting such initiatives. At best, literature considers government as an obstacle to the development of SBMs in the BOP context. In this paper, we challenge that view by presenting the case of the Ecoelce project, an SBM developed in the BOP context of Northeastern Brazil. We show that this project transformed a coercive pressure from the Brazilian government into a strategic opportunity and a source of shared value. We argue that the mobilization of native capability was key in this process. © 2016 Elsevier Ltd.

This study, a qualitative investigation anchored in Foucaltian analysis with approximations to post-structuralist theory, explores the question of autonomy as one of the tensions of nursing performance/knowledge which can be discursively articulated to bioethics and to techno biomedicine. From such perspective, from the multiples vies that may emerge to completing a critical reading of the analyzed texts (articles produced by nurses) and of the interviews with intensive care nurses, the theme of autonomy was analytically explored from the concept of self care, unfolding itself into categories which express privileging: morals as obedience to the Law; conduct and morals concerning technical knowledge; self-governing in its confront with technique. These are configured as ethical possibilities for the intensive care nurse/subject, not as sequential or competitive stages, but connected and confluent in the experience of the current historical period.

Current mobile devices have an extensive amount of new features, one of them being the location by GPS (Global Positioning System). However, this feature suffers from the problem of indoors availability. As an alternative to this problem, this paper presents the model Here I Am, which uses NFC (Near Field Communication) technology as a means of interaction with the environment and the user, thus allowing the indoor location. To develop the model, concepts of Mobile and Ubiquitous Computing, NFC Technology and Ubiquitous Location Systems were used. The model Here I Am, includes the development of a Web application, for managing the solution, and an application for the Android platform, for users' location and navigation. We evaluated the model by developing prototype, which was evaluated in terms of four aspects: (i) usability; (ii) effectiveness; (iii) efficiency; and (iv) user satisfaction. The results were encouraging and very positive, demonstrating the interest of users in the Here I Am model.
