UNLABELLED Chronic human exposure to formaldehyde is significantly increased by indoor sources. However, information is lacking on why these exposures appear to persist in older homes with aging sources. We use data from the Relationships of Indoor, Outdoor, and Personal Air study to evaluate 179 residences, most of which were older than 5 years. We assess the dependence of indoor formaldehyde ...

BACKGROUND Understanding and applying human factors in healthcare provides significant opportunities for improving patient safety. A key human factors concept is "resilience," which investigates how individuals, teams and organisations monitor, adapt to and act on failures in high-risk situations. Although it is a new concept to healthcare, it is well accepted in other high-risk industries. Res...

A method measuring vertical upwards total radon soilgas flow from the ground through building sites before construction is investigated as a predictor for the radon concentration inside a home after construction. The theory for this radon risk evaluation (RRE) is derived and simple analytical and more realistic numerical examples are given. Data obtained from short term radon tests inside homes...

Recent works in the safety literature report several fruitful attempts to introduce mathematically rigorous results from systems and control theory to bear upon accident prevention and system safety. Previously, we discussed the implications on safety of the systems theoretic principles of coordinability and consistency, and we identified the lack of coordinability and/or consistency as fundame...

When building homes, sustainability principles should be followed throughout the process to achieve maximum advantages. Building information modeling (BIM) activities can aid in achieving sustainable goals. Third-world countries’ industry implements informal approaches dissemination through email newsletters and websites. This research seeks provide a model for application of BIM its relationsh...
