Heart failure belongs to the categories of “chest paralysis”, “wheezing” and “edema” in traditional Chinese medicine. The disease is induced by a variety of reasons, the initial stage of the disease is mostly manifested as palpitations, shortness of breath, chest tightness and other symptoms, with the progression of the disease, severe cases often appear with abnormal changes in heart structure and function, mainly manifested as dyspnea, fatigue and systemic edema. Traditional physicians believe that its onset is mostly related to long-term illness or old age and physical decline, qi and blood yin and yang deficiency, so Zhang Xichun’s theory of “atmospheric depression” is used to treat the disease, and clinically commonly used Shengxi soup treatment, with the method of tongli, using tonic tongli products to achieve reality and become more serious, so that the right qi can be replenished, the qi machine is smooth, the water metabolism is smooth, and the diseases can be eliminated. However, the clinical treatment of this disease is mainly based on decoctions, and this article analyzes Zhang Xichun’s theory of “atmospheric subsidence”, the systemization of the five elements of yin and yang, and the method of modern doctors using acupuncture to supplement tongli, in order to provide new ideas for the clinical treatment of chronic heart failure edema.展开更多

Despite the wide distribution of air pollutant sources, the concentration of indoor pollutants may be the dominant risk factor in relation to personal exposure, as most people spend an average of 87% and 6% of their time within enclosed rooms and vehicles, respectively. Under these circumstances, wind driven rotating ventilators, which use natural energy and are cheap to manufacture, install and maintain, can become very effective non-polluting means of alleviating the problems within enclosed spaces. The author has been pioneering design and performance studies of environment friendly products such as the rooftop ventilator for over a decade at the University of New South Wales in Australia. The purpose of this paper is to detail the basic working principles of this ventilator and the series of detailed experimental and numerical investigations that has been performed in the optimization of the rooftop ventilator in terms of performance with higher air mass extraction rate and improved safety in operation has been achieved. Findings from these studies have been incorporated in the design of ventilators that are now commercially produced and marketed throughout the world by CSR Edmonds Pry Ltd of Australia. The conduct and outcomes of these works form the basis of this keynote paper.展开更多
