Natação Adaptada: análise da função pulmonar de pessoas com deficiência

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...

Contração de polimerização e expansão higroscópica de resinas compostas: análise pela técnica de video-imagem

To evaluate the volumetric changes due to polymerization and thermocycling on different resin-composites. Methods: Thirteen A2 Universal Dentin shade resin-composites (n = 10) from eight manufacturers were evaluated (4Seasons, Grandio, Venus, Amelogen Plus, P90, Z350, Esthet-X, Amaris, Vita-l-escence, Natural-Look, Charisma, Z250 and Opallis). The polymerization shrinkage percentage (PS) was calculated using an image measurement device (ACUVOL - Bisco Dental). Equal volumes of material, standardized by a semisphere polyurethane matrix (d = 3mm) were used and, after 5 minutes of relaxation, the baseline volume measurements were obtained with 18 J of energy dose from the LED light-curing unit. Measurements were obtained after 5 minutes and PS values calculated. Specimens were stored in a drydark environment for 24 hours and re-measured. Specimens were then thermocycled in distilled water between 5oC and 55oC for 20,000 cycles, subjected to another volume measurement at 5,000 cycle intervals. Specimens were gently dried prior to each measurement. Results: Repeated measurements were made using ANOVA (α = 0.05) showed that all resin-composite volumes were influenced by the number of cycles. Volumes at 5 minutes post-polymerization (12.47 ± 0.08) were significantly lower than those at baseline (12.80 ± 0.09). Volumes at 24 hours (12.43 ± 0.19) were insignificantly lower than those at 5 minutes postpolymerization. With regards to the impact of thermocycling, all specimens showed statistically significant increases in volume after 5,000 cycles (13.04 ± 0.22). Although statistically different from those after 5,000 cycles, there was no statistically significant difference between volumes measured at 10,000 (12.87±0.21), 15,000 (12.92±0.24), and 20,000 (12.84±0.23) cycles. Conclusion: According to the video-imaging analysis, thermocycling caused a significant expansion in resin-composites tested, the volume increase was not able to...

Otimização de método para analise de tebutiurom, diurom e seus produtos de degradação em água superficial

In 2001, it was estimated that pesticide used worldwide exceeded 2.27 billion kilograms, over 35%, of which, were herbicides. Brazil is considered one of the leaders in the production of sugarcane and mainly ethanol as fuel. The monoculture of sugarcane requires the usage of a range of pesticides, among these, the herbicides diuron and tebuthiuron. The degradation products most studied (DCA and DCPU) are diuron's, especially for toxicological characteristics of this herbicide that is identified as carcinogen and suspected to be endocrine disruptor in mammals. After optimization of the chromatographic separation using HPLC-UV, the analytical curve was constructed in solvent and subsequently in the matrix (surface water). The extraction method contains the usage of SPE (solid phase extraction) (Strata-X, 200 mg/6 mL), applicating 1L of sample and elution with 5 mL of acetonitrile / methanol (50:50, v/v). Analysis by HPLC/UV was performed in gradient mode, acetonitrile/water (70/30-74/26 by 1 min, 74/26 - 78/22 till 3.2 min, returning to initial conditions and remaining this way until 10 min), 018 column (Phenomenex, 4.6 mm diameter, 250 mm long and 5pm particle size) and detection at 254 nm. Tests F and t were performed to verify the presence of the matrix effect. There was matrix effect to all analytes, ranging from -33% (DCA) and 38% (tebuthiuron). Thereby the method was optimized and validated for analysis of diuron, tebuthiuron, and DCPU DCA in surface water using HPLC/UV. The data obtained show that in order to assure the analytical reliability desired the use of the analytical curves in the matrix for the quantification of these analytes in water is required.

Concentração de flúor em águas envasadas: análise laboratorial e da legislação relacionada

Fluoridation of water for human consumption is a method of caries prevention that brings great social benefit, if kept at optimal levels. The increase in the production of bottled water emphasizes the need to verify whether fluoride presence in these waters occurs in sufficient quantity to prevent decay, or if it represents a significant risk of fluorosis. Objective: to compare the concentrations of fluoride present in bottled water to those declared on the labels, and to make a critical analysis of legal norms on the subject. Materials and method: this was a cross-sectional study, through which 22 samples of bottled water sold in state of Ceará, Brazil, were analyzed. Analyses were performed in duplicate by the electrometric method, and results were compared to those printed on the labels. Detailed searches by laws, resolutions, ordinances, and other official documents in force, related to the topic were performed. Results: the fluoride concentrations found ranged from 0.01 to 0.36 mgF/l. Although 72.7% of the samples were classified as fluoridated, the fluoride concentrations observed were shown to be insufficient for caries prevention. As for the rules, situations where they are not clear or even divergent were found. Conclusion: the current legislation on the subject requires updates to become more objective and to create new criteria on the use of the term “fluoridated water”.

Procedimentos para o dimensionamento de reservatório de água pluvial para residências unifamiliares: viabilidade e aprimoramento metodológico

This paper focus to apply, to discuss and to propose the Maximum Harvesting Method improvement, regarding the method application, for household rainwater harvesting systems. For this purpose, the rainwater was considered to supply the flush toilet demand in a household for 3, 4, and 5 inhabitants. The 80, 120 and 200m2 catchments areas and the 0, 1, 2 and 4mm first flushes discharges were also considered. Further, the improvement suggestions for cistern volume calculus and volume/level dynamics variation in a period were presented and the results were compared applying the Simulation Analyses Method. The results indicate that the Maximum Harvesting Method could be applied and that the improvement proposal can be used to determinate the cistern volume as well to analyze the dynamic behavior of volume/level, constituting by itself a single tool to assist rainwater harvesting systems designers.
