This paper is an extension of an earlier work on “building regulations‟ impact on natural ventilation in Dhaka‟s apartment buildings”. Four schemes of building regulations (each offering different „maximum allowable footprint‟ with a different „maximum building height‟) were examined. Due to unavailability of large computation resource, only bottom floors, least privileged in terms of wind acce...

This study assessed pesticide residues in soils, sediments, and vegetables in the Xuan Khe and Hop Ly communes located along the Chau Giang River in the Red River Delta, northern Vietnam. Samples were collected from agricultural areas within and outside of embankments built to prevent flooding. In Xuan Khe, the soils outside of the embankment were more clayey with higher organic matter contents...

conditional monitoring is prerequisite to prevent severe damage or falling down the trees. problems such as trunk decays, reduces trees resistance against wind and floods. in this study, a mathematical modeling technique is being selected to determine the trees strength against such events. finally, an applicable model for safety factor was created by having numeral (dimensions of crown and tru...

The study aimed to explore chronotype-specific effects of two versus four consecutive morning or night shifts on sleep-wake behavior. Sleep debt and social jetlag (a behavioral proxy circadian misalignment) were estimated from sleep diary data collected for 5 weeks in a within-subject field 30 rotating shift workers (29.9 ± 7.3 years, 60% female). Mixed models used examine whether sequence leng...

Internationally several phthalates are subject to regulatory control regarding maximum allowable concentrations in children's toys. Such regulation is not in place in New Zealand. Phthalates have been associated with developmental toxicity and endocrine disruption. We determined the concentration of seven phthalates in children's toys purchased in Christchurch, New Zealand. These results provid...
