Research ArticleOpen accessIn the abstractIndoor Environmental Comfort in Malaysian Urban HousingYaik-Wah LimIn Malaysia, terraced houses have been rapidly constructed since 50 years ago and account for 44% of the existing urban housings. However, these houses have very limited use of natural ventilation and daylighting due to openings with small window-to-floor ratio. The deep plan design causes gloomy indoor spaces, low air change rate and poor indoor air quality. Studies showed that … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 22 Nov 2013 · 7,467 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAirway Metrics, Anatomy and Growth Performance of Pigs Reared Indoors and OutdoorsChakia Joi McClendon, Sherrell Pettiford, Dawn Conklin et al.While the swine industry has made incredible strides to improve ventilation, air quality in confinement buildings remains an issue. The goal of this study is to characterize correlation between large airway metrics and growth performance in piglets reared indoors and outdoors on pasture. Three experimental trials were conducted: Trial 1 included three breed types that were strictly raised indoors, Tamworth … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,582 accessesView PDF Cite
