1. Post-Occupancy Evaluation of an educational building: Case study of the ETS-UESC Building
Abstract The physical and environmental conditions of educational institutions are determining factors for occupant comfort. The Post-Occupancy Evaluation (POE) presents itself as a methodology for verifying environmental aspects in full use, considering the technical criteria and the users' perception. This article discusses the particularities of the ETS-U

2. Study using a CFD approach of the efficiency of a roof ventilation closure system in a multi-tunnel greenhouse for nighttime microclimate optimization
ABSTRACT The thermal efficiency of naturally ventilated greenhouses is limited due to the permanent exchange of air through the vents, especially during the night hours. The objective of the work consisted in evaluating a system of inflatable air ducts that close the roof vents during the night as a strategy to reduce the energy loss during these hours. For

5. Organic solvent exposure and contrast sensitivity: comparing men and women
The goal of this study was to compare the visual contrast sensitivity (CS) of men and women exposed and not exposed to organic solvents. Forty-six volunteers of both genders aged between 18 and 41 years (mean±SD=27.72±6.28) participated. Gas station attendants were exposed to gas containing 46.30 ppm of solvents at a temperature of 304±274.39 K, humidity

6. Oxidative stress and immune system analysis after cycle ergometer use in critical patients
OBJECTIVE: The passive cycle ergometer aims to prevent hypotrophy and improve muscle strength, with a consequent reduction in hospitalization time in the intensive care unit and functional improvement. However, its effects on oxidative stress and immune system parameters remain unknown. The aim of this study is to analyze the effects of a passive cycle ergo

7. Estudo da eficiência para a ventilação natural dos sheds em hospitais da Rede Sarah / Study of the efficiency of natural ventilation of sheds Sarah network in Hospitals
Natural ventilation in tropical regions is an efficient design strategy for achieving thermal comfort and reducing energy consumption. The utilization of natural resources and climate conditions improves integration of the building with its surroundings and allows comfort conditions through passive systems of conditioning. The effects of wind on a building a

8. Isolation of pathogenic yeasts in the air from hospital environments in the city of Fortaleza, northeast Brazil
This paper reports the results of environmental surveillance of yeasts in specific areas of two tertiary local hospitals. From March 2007 to February 2008, samples from the air of two public hospitals were collected on a monthly basis. The samples were collected through passive sedimentation method (day and night exposure) of Petri dishes. A total of 240 air

9. Análise de métodos para aplicação de ventilação natural em projetos de edificações em Natal-RN
Natural ventilation is an efficient bioclimatic strategy, one that provides thermal comfort, healthful and cooling to the edification. However, the disregard for quality environment, the uncertainties involved in the phenomenon and the popularization of artificial climate systems are held as an excuse for those who neglect the benefits of passive cooling. Th

10. Análise dos marcadores bioquímicos fosfatase alcalina óssea específica e deoxipiridinolina no metabolismo ósseo de recém-nascidos pré-termo submetidos a fisioterapia motora
Introduction: Preterm infants need minimal handling in order to protect them from stress, resulting in bone resorption and demineralization. Objetives: To evaluate bone formation in newborn preterm infants before and after a physical therapy protocol, by means of biochemical markers bone-specific alkaline phosphatase (BAP) and urinary deoxypyridinoline (DPD)

11. Thermal performance of a castor oil foam as insulating material inside the roof : study case in the city of Ilha Solteira, Brazil / Desempenho termico da espuma poliuretana a base de oleo de mamona utilizada em componentes da edificação (subcoberturas) : estudo em Ilha Solteira, SP
The aim of this work is to describe an experimental study using castor oil foam as an insulating material inside the roof. The castor oil foam inside the roof is an appropriate natural recycled material as a passive cooling strategy as opposite to the burning of fossil fuels for air conditioning (AC) and mechanical ventilation. The expected result of this re

12. Estudos exploratórios sobre ventilação natural por tubos enterrados
O uso do solo como massa inercial para condicionamento térmico de edificações por contato direto é uma prática antiga, porém, seu uso como trocador de calor através de dutos enterrados, para ventilação natural de edificações é recente. A prática consiste em enterrar dutos a profundidades entre 0,5m e 1,5m – com extensões e diâmetros variáve
