conclusions the presence of fungi in the nasal cavity and indoors of healthy subjects in this study suggests that fungi should be considered as health hazards. furthermore, it is important and seems necessary to monitor indoor air quality and raise awareness of existing threats due to microorganisms, including fungi. results the most common fungi isolated from all samples were aspergillus, peni...
Background and purpose: High concentrations of respirable particles in both the outdoor and indoor environments are associated with adverse health effects that could reduce the performance of students. This study was carried out to investigate the indoor concentrations of respirable particle and outdoor concentrations of PM2.5 at classrooms in primary schools in Sari, north of Iran. We also eva...
Few biologists have studied the evolutionary processes at work in indoor environments. Yet indoor environments comprise approximately 0.5% of ice-free land area--an area as large as the subtropical coniferous forest biome. Here we review the emerging subfield of 'indoor biome' studies. After defining the indoor biome and tracing its deep history, we discuss some of its evolutionary dimensions. ...
BACKGROUND Indoor human environments, including homes, offices, schools, workplaces, transport systems and other settings, often harbor potentially unsafe microorganisms. Most previous studies of bioaerosols in indoor environments have addressed contamination with bacteria or fungi. Reports on the presence of viral aerosols in indoor air are scarce, however, despite the fact that viruses are pr...
gamma rays pose enough energy to remove electrons from atoms of absorbing material including human body and adversely affect human health. the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined. therefore, we monitored gamma dose rate in indoor environments and estimated corresponding annual effective dose in selec...
We live in a 3D world, performing activities and interacting with objects in the indoor environments everyday. Indoor scenes are the most familiar and essential environments in everyone’s life. In the virtual world, 3D indoor scenes are also ubiquitous in 3D games and interior design. With the fast development of VR/AR devices and the emerging applications, the demand of realistic 3D indoor sce...
