Statistics for psoriatic patients from the skin clinics of the Hong Kong Government and those from Sendai, Japan, are compared with statistics from five major cities in mainland China. These statistics were compiled since 1949, following the establishment of the People's Republic of China. Additional statistics from seven other surveys among the general(More)
A vertical axis wind turbine (VAWT) was positioned at the discharge outlet of a cooling tower electricity generator. To avoid a negative impact on the performance of the cooling tower and to optimize the turbine performance, the determination of the VAWT position in the discharge wind stream was conducted by experiment. The preferable VAWT position is where(More)
A case of cutaneous infection due to a niacin-positive Mycobacterium chelonei (previously called M. abscessus) on the dorsum of the hand of a professional cotton-classifier is reported from Hong Kong. The infection was probably directly acquired from handling contaminated raw cotton. The patient was successfully treated with combined anti-tuberculous drugs(More)
This paper describes the development of a model of an exhaust air wind energy recovery system with adjustable guide-vane. The model is developed by using a curve fitting approach with polynomial regression analysis; it correlates the fan speed, guide-vane angle, wind turbine rotational speed and duty cycle of the resistive load to electrical power. It can(More)
