Recently, midge larvae, which are indicators of aquatic environmental pollution, have been detected in tap water some areas, resulting controversy. Therefore, the objective this study is to analyze behavioural features larvae sand, GAC (granular activated carbon) and GAC/sand processes, mainly operated domestic purification plants, suggest effective operating methods for larval control. In stud...

Expressing spatial information with iconic gestures is abundant in human communication and requires to transform a referent representation into resembling gestural form. This task is challenging as the mapping is determined by the visuo-spatial features of the referent, the overall discourse context as well as concomitant speech, and its outcome varies considerably across different speakers. We...

English intonation can be difficult for L2 speakers to learn, particularly for those whose L1 intonation system works differently from English. This study investigates whether Hong Kong English (HKE) speakers whose L1 is Cantonese have knowledge of the appropriate English intonation patterns in specific contexts. Results from an intonation pattern selection tasks indicate that HKE speakers (n =...

In this paper, moment-curvature behavior and ductility of prestressed concrete members based on nonlinear analysis is investigated. Influence of various design parameters on ductility of flexural members is determined according to appropriate materials models for stress-strain curves of concrete, prestressing steel and conventional reinforcements. Parameters studied include reinforcing index (ω...

A Water Exclosure Treatment System (WETS) is developed and installed to minimize the occurrence of beach closures due to algae and Escherchia coli (E. coli) in an inland lake. WETS consists of an "exclosure" sub-system with a five-sided polypropylene, barrier that excludes offshore lake contaminated water from the swimming area. Inside the exclosure, water is pumped to a portable filtration-ult...
