PolyU study reveals effectiveness of GBGI infrastructure in mitigating urban heat

Prof. GUO Hai, Management Committee Member of the Research Institute for Land and Space (RILS), Member of the Research Institute for Sustainable Urban Development (RISUD) and Professor in the Department of Civil and Environmental Engineering, together with global researchers, have conducted a first-of-its-kind study on the effectiveness of green-blue-grey infrastructure (GBGI) in cooling urban heat across various regions. The study findings have been published in the international interdisciplinary journal The Innovation. The study revealed regional and city-specific variations in the effectiveness of GBGI for mitigating urban heat. In Europe, Asia, North America and Australia, the overall cooling effect of GBGI is up to 18.9°C, 17.7°C, 12°C and 9.63°C respectively. In addition, the implementation of green and blue infrastructures has proven to be highly effective in lowering air temperatures globally. While green infrastructures can regulate urban heat through evaporation, transpiration, shading and thermal insulation, blue infrastructures absorb heat and cool the surrounding area through evaporation. The study also showed notable effects of various GBGI features in mitigating urban heat in Mainland China cities. The most effective means include botanical gardens, wetlands, green walls and attenuation ponds which exhibited temperature reductions of up to 10°C, 9.27°C, 8°C and 7°C respectively. Although the cooling effect ranges are generally similar in the north and south of China, there is variability within the same region. For example, in Beijing, botanical garden could result in up to 10°C temperature decrease while that in Shaanxi province only contributed to 2.7°C. In Hong Kong, parks, green roofs and golf courses were found to play substantial roles in cooling urban heat, resulting in temperature reductions of 4.9°C, 4.9°C and 4.2°C respectively.

Prof. WU Bo shares on deep space explorations research and I&T development with media

Prof. WU Bo, Associate Director of the Research Centre for Deep Space Explorations (RCDSE), in an exclusive interview with GD Today, shared on the research works by his team and Hong Kong’s innovation and technology (I&T) development. Prof. Wu and his team are currently working on the topographic mapping for Chang’e-7 and Tianwen-2 missions, using remote sensing data to build topographic maps of the Moon and Mars, and using topographic analysis techniques to evaluate and select possible landing sites that are safe and scientifically valuable. In the interview, he mentioned that since the team does not have any readily available information and data, this has brought great difficulties to the team’s mapping and remote sensing analysis works for the Tianwen-2 mission. The team has built a test site inside the laboratory, hoping to simulate the actual environments for analysis, and to enable improvements and enhancements in surveying, mapping and remote sensing so that these methods can be used for the effective measurement and analysis of irregular stellar objects, as well as the selection of possible landings sites for analysis and tracking in the future. He also mentioned that the team has made use of artificial intelligence technology to process satellite images, which has greatly improved research efficiency and reliability. Prof. Wu also pointed that given the increasing emphasis on innovation and technology in Hong Kong, as well as closer exchanges and co-operation between Hong Kong and other cities in Mainland China, Hong Kong researchers should actively seize the research opportunities ahead of them, bringing impetus to the development of Hong Kong, the Greater Bay Area and the Nation.

Prof. Amy FU expounded upon the causes and symptoms of knee pain in the elderly

Prof. Amy FU, Peter Hung Professor in Pain Management, Associate Head and Professor of the Department of Rehabilitation Sciences and Associate Director of the Research Institute for Sports Science and Technology (RISports), wrote an article in Ming Pao to elaborate on the causes and symptoms of knee pain in the elderly, as well as related knee care solutions. PolyU research has shown that muscle tension and lack of strength in the foreleg are the causes of early knee degeneration. As our muscle mass, strength and flexibility decrease with age, the ability of our knees to absorb shock reduces, causing overload in the knees. In addition, many elderly people do not swing their arms and have their upper bodies swinging from side to side like a pendulum when they are walking. This not only causes difficulty in walking, but also increases the load on the knees. Therefore, the muscles of the hips, thighs, calves, and lower back all need to have good strength, flexibility, softness, and coordination to reduce the load on the knees. Prof. Fu mentioned that excessive load on the knees during walking is the main cause of pain. Therefore, the lower limbs must maintain balance so that the knees are gradually bent to reduce the load on knees when walking. In addition, we should move our legs and swing the opposite arms forward when walking, and this can save walking energy if the whole body is coordinated. She also pointed out that muscle mass reduces with age, with 8% loss of muscle mass every 10 years after the age of 40 and 15% loss of muscle mass every 10 years after the age of 70. Therefore, starting exercises early to strengthen our knees and doing exercises consistently can help reduce muscle loss effectively and maintain strong and flexible muscles, thus improving knee health and reducing the risk of falls.

Prof. YUNG Kai-leung invited to witness launch of Chang’e 6 lunar probe in Hainan

Prof. YUNG Kai-leung, Director of the Research Centre for Deep Space Exploration (RCDSE) attended the Symposium on Chang’e-6 Mission for International Payloads in Wenchang, Hainan on 3 May and were invited to witness the launch of the Chang’e-6 lunar probe. The probe is equipped with the “Surface Sampling and Packing System” developed by Prof. Yung’s team in collaboration with China Academy of Space Technology (CAST), which will be used to collect and package lunar regolith samples. Prof. Yung said that Chang’e 6’s mission to retrieve samples from the far side of the Moon is of great significance, and this is much more difficult and challenging than retrieving so on the front side of the Moon. The mission requires support from Queqiao-2 relay satellite due to poor communication on the far side of the Moon, and requires enhanced samplers for rapid sampling since the sampling time is shorter than that in Chang’e 5 mission. He said that the “Surface Sampling and Packing System” included the two samplers, two accompanying high temperature nearfield cameras and a primary sealing and packaging system that consisted of a sample container and its sealing mechanism. If they can successfully assist the Nation in obtaining soil from the far side of the Moon and bringing it back to Earth, this may contribute to the study of the Moon, the formation of the Universe, as well as the impact of solar wind on the Moon.
