Abstract: the authors report two cases of pulmonary artery sling diagnosed by three-dimensional reconstruction of images of the tracheobronchial tree and the esophagus acquired using magnetic resonance imaging or helical computer tomography. the typical clinical findings of this congenital abnormality, which may not be as rare as previously believed, include those related to severe tracheobronchial obstruction, although asymptomatic or mild symptomatic cases have been reported. early diagnosis of this anomaly is extremely important, since in most cases immediate surgical correction is indicated due to its high lethality. the use of three-dimensional reconstruction allows simultaneous identification of the associated tracheobronchial and cardiovascular malformations, in addition to a clear visualization of the anomaly. thus, the diagnosis can usually be established non-invasively, avoiding the use of the selective angiocardiography, considered the gold-standard.

An Integrated Approach for Process Control Valves Diagnosis Using Fuzzy Logic  [PDF]
Alvaro Luiz G. Carneiro, Almir C. S. Porto Jr.
World Journal of Nuclear Science and Technology (WJNST) , 2014, DOI: 10.4236/wjnst.2014.43019
Control valves are widely used in industry to control fluid flow in several applications. In nuclear power systems they are crucial for the safe operation of plants. Therefore, the necessity of improvements in monitoring and diagnosis methods started to be of extreme relevance, establishing as main goal of the reliability and readiness of the system components. The main focus of this work is to study the development of a model of non-intrusive monitoring and diagnosis applied to process control valves using artificial intelligence by fuzzy logic technique, contributing to the development of predictive methodologies identifying faults in incipient state. Specially in nuclear power plants, the predictive maintenance contributes to the security factor in order to diagnose in advance the occurrence of a possible failure, preventing severs situations. The control valve analyzed belongs to a steam plant which simulates the secondary circuit of a PWR—Pressurized Water Reactor. The maintenance programs are being implemented based on the ability to diagnose modes of degradation and to take measures to prevent incipient failures, improving plant reliability and reducing maintenance costs. The approach described in this paper represents an alternative departure from the conventional qualitative techniques of system analysis. The methodology used in this project is based on signatures analysis, considering the pressure (psi) in the actuator and the stem displacement (mm) of the valve. Once the measurements baseline of the control valve is taken, it is possible to detect long-term deviations during valve lifetime, detecting in advance valve failures. This study makes use of MATLAB language through the “fuzzy logic toolbox” which uses the method of inference “Mamdani”, acting by fuzzy conjunction, through Triangular Norms (t-norm) and Triangular Conorms (t-conorm). The main goal is to obtain more detailed information contained in the measured data, correlating them to failure situations in the incipient stage.

Abstract: heavy metals, also called trace elements, may be essential to the metabolism of living organisms, and at the same time, depending on their concentrations, highly toxic. with the objective to investigate the toxicity of water of the butuí-icamaqu? rivers basin on the border west of rio grande do sul, were analyzed by atomic absorption spectrophotometer, the contents of aluminum, cadmium, chromium, copper, lead, manganese, nickel and zinc in abdominal viscera of fish, collected between june 2007 and february 2008, at selected points in butuí, icamaqu? and uruguai rivers. aluminum, cadmium, manganese and nickel were above the levels considered safe for human consumption and levels near the legal limit were found for chrome and copper. the simultaneous analysis of water samples collected in the same locations showed levels above the legal limits of bromine, chromate, copper, cyanide, lead, manganese, phenols, phosphate and sulfate. these elements, in such concentrations in water and in fish, may compromise the ecosystem or pose risks to human health.
Effects of a 12-Week Systematized Yoga Intervention on Health-Related Physical Fitness in Healthy Adults  [PDF]

Regular physical activity has been shown to improve overall physical fitness. The long-term adherence to physical activity is a big challenge for health maintenance; so, pleasure activities, as Hatha Yoga (yoga), may represent a good alternative on both individual and public contexts. Yoga is an ancient activity designated to both health and unhealthy individuals. It integrates physical, mental, and spiritual components and may improve aspects of health. The aim of the present study was to evaluate the effects of a 12-week systematized yoga intervention on health-related physical fitness components assessed by body mass, body mass index (BMI), waist circumference (WC), relative body fat, abdominal endurance, upper body endurance, hamstring flexibility, and cardiorespiratory fitness. The study was performed at University of Brasília, Faculty of Physical Education, Distrito Federal, Brazil. Twenty-five young healthy yoga novices (22.36 ± 2.40 years), both gender, volunteered to participate in this study. The intervention was based on 50 minutes yoga class, twice a week for 12 weeks, involving physical poses, meditation, and relaxation. Measurements were performed one week prior to and one week after the yoga intervention. Collecting data included age, gender, height, body mass, body fat estimates and physical fitness tests. Body fat percentage was determinated by the measure of skinfolds at seven sites. Muscle strength/endurance was evaluated by push-up and sit-up tests. Hamstring flexibility was assessed using sit-and-reach test protocol. The 12-minutes Cooper test was performed to estimate cardiorespiratory fitness. Participants that attended at least 75% of the total sessions were included in the study results. The results showed 1.3 (1.0 - 4.0) cm decrease in WC and 0.7 (0.9 - 1.5) decrease in body fat percentage, and 7.8 (2.0 - 5.0) cm increase in hamstring flexibility and 3.0 (1.0 - 4.0) in abdominal endurance, after the yoga intervention (p < 0.01). In conclusion, the present study found that a 12-week yoga program improved physical fitness in young healthy subjects.
A arara-azul-de-Lear, Anodorhynchus leari Bonaparte, 1856

Abstract: the case of the indigo, or lear's macaw, anodorhynchus leari, is unique in south american ornithology. the species, although described more than 100 years ago, was known only through very few living specimens, which entered occasionally the bird trade, without any indication of their origins. it was presumed "probably some part of brazil" (salvadori, 1891). the last speculation was that it was unlikely, though not impossible, that the indigo macaw might not be an independem species, but rather, a hybrid between the two other well known blue macaws, anodorhynchus hyacinthinus and a. glaucus (voous, 1965).
