Introduction: Obstructive sleep apnea syndrome is related to cardiopulmonary complications in children. It is important to know its patophysiology and possible complications to help reduce risks in this group. Aims: To report three cases of severe cardiorespiratory complications of obstructive sleep apnea managed in the intensive care unit (ICU). Case report: Two children with no previous diagnosis of obstructive sleep apnea syndrome suffered acute congestive heart failure and acute lung oedema with need of ICU and improved after adenotonsillectomy. In a third case, the patient had acute lung oedema as a complication after adenotonsillectomy. Conclusions: Paediatricians and otolaryngologists must be aware of the clinical manifestations of severe sleep apnea. Early referring to treatment and special attention at pre and post surgical periods are essentials to avoid serious complications.

Model: Prevalence study. Objectives: To evaluate the presence of self-reported hypertension to compare with blood pressure measurements. Besides, this work investigated health information level of workers and if the job position has any influence on blood pressure (BP). Methods: This study evaluated 349 health workers (44±10 years old) from Bauru and Jau cities, who answered some questions about history of health condition, use of medicines, past surgeries as well as social, scholar and physical conditions and had their blood pressure measured. Each subject selfreported as normotensive or hypertensive. Values of systolic ≥ 140 mmHg and/or diastolic PA ≥ 90 mmHg were considered elevated. Among the health workers evaluated, 198 were submitted to anthropometric and biochemical evaluations. Values are presented as means ± SD and frequency of distribution. It was used T-student test (p<0.05). Results: From all workers evaluated only 16% self-reported as hypertensive, which 56% presented high BP, however 91% used to take antihypertensive medicines. Among the 84% who self-reported as normotensive, 24% presented high BP and 8% used to take medicines. Although most of the employees of each section self-reported as normotensive, more than a half presented high BP and which was more common in the health's section (76.3%). Conclusion: These results suggest that besides the majority of the employees self-reported as normotensive, an elevated number of health workers presented high blood pressure and used to take medicines inappropriately, which indicates that they did not have enough knowledge about their health. Furthermore, it was observed that Health Section presented the higher blood pressure values.

In the Morrinhos region, Goiás state, Brazil, the rocks of the Araxá Group have mineral assemblages related to the metamorphic peak which occurred in this region and is typical of the amphibolite facies (kyanite zone). These rocks are associated with the initial stage of the main ductile deformation that occurred in this area. Thermobarometric calculations, including the associations, garnet + plagioclase + biotite + muscovite; garnet + plagioclase +biotite + muscovite + kyanite; garnet + plagioclase + biotite + muscovite + amphibole, with quartz in excess, indicate that the metamorphic peak occurred at temperatures of approximately 610°C and pressures in the order of 10 kbar. The P-T path is probably clockwise and is in agreement with the tectonic conditions observed in collisional settings.

An experimental apparatus containing a domestic refrigerator coupled to a vertical hot water storage tank was used for energy recovery. The original condenser of the refrigerator was maintained, but modified with a concentric tubes heat exchanger with countercurrent water and refrigerating gas flows. The coefficient of performance for the heat pump is calculated by the ratio of energy in the heat storage and the electric power consumed by the domestic refrigerator compressor. The results show that the increasing of hydrostatic pressure in the storage tank increases the water flow rate and the coefficient of performance. The proposed device also reduces the heat dissipation to the surroundings. This is more important in small confinements found in low-cost houses.

This study aimed to determine the crop evapotranspiration (ETc) and crop coefficient (Kc) of fertigated sweet pepper, measured over time (15, 30, 45, 60, 75, 90 and 105 days after the transplant). The experiment was conducted on a battery of 40 drainage lysimeters, arranged in a 8 x 5 matrix, in the period October/2009 to January/2010, located in the Federal Rural University of Pernambuco (UFRPE) Campus in Recife, in a completely randomized factorial scheme 5 x 2, with four replications, being five irrigation depths (80, 90, 100, 110 and 120% of ETc) and two levels of potassium (80 and 120 kg K2O ha-1) where the experimental plot was composed of three plants in each lysimeter. The Mauchly Sphericity Test indicated multivariate variance analysis for the studied variables ETc (mm d-1) and Kc, the variables presented adjustment under quadratic effect of variation on observation times, when the irrigation depths were fixed, and descending linear adjustments under the variation of irrigation depths effect, when the times of observation were fixed in each potassium dose.
