Shenzhen is one of the most dynamically growing cities in the world with a population of more than 10 million. Situated in the Pearl River Delta (PRD) in China it is in the powerhouse of the global economy. Some decades ago Shenzhen was a small fishing village only, however, after its designation as a Special Economic Zone (SEZ) the city has gone through rapid urbanization and industrial development. Therefore, currently, Shenzhen is one of the leading economic hubs of China, an important gateway of the large Chinese economy, and a sub-provincial administrative centre in the PRD.

Sungang-Quingshuihe (SQ) is a neighbourhood of 2.5 square kilometres, in Louhu district in the east of Shenzhen. The landscape system of SQ has been largely destroyed and fragmented by developments. Our main goal is to redesign SQ neighbourhood for an innovative growth centre of Shenzhen. We envisage SQ as a liveable area with new and modern functions for international residents who work in higher education, information communication industry, medical services, R&D facilities of multinational corporations, and research-oriented start-up companies. In order to accomplish this vision it is required to design new transportation system, public buildings, housing, green corridors and parklands.

Abstract

The availability of freshwater is increasingly becoming an international concern because of the increase in population and the diminishing forest area as a source of water, leading to a freshwater crisis. The coastal and swamp areas abound in water, but humans cannot consume it due to the quality. One effort that can be done in overcoming this problem is by treating existing raw water with solar distillation methods. However, the main obstacle faced in this method is the intensity of sunlight that is not stable throughout the day so that the productivity of distilled water is disrupted. Using the appropriate phase change material (PCM) is expected to make the distillation process smoother and increase the production of pure water. In this study, myristic acid was used as PCM in double slope solar distillation system. Through observation, it was obtained that the average water temperature in the basin equaled to 42.5 °C while the melting point of the myristic acid was 58 °C. This shows that the use of myristic acid as an energy storage through phase change process does not occur. Therefore, the use of myristic acid as PCM for increasing the productivity of solar distillation in these experiments is not effective because the melting point of PCM is higher than water temperature in the basin. Therefore, material with a phase change temperature below 42.5 °C is more appropriate to use in these conditions.

Abstract

Sida hermephrodita or Virginia mallow is a perspective perennial herb in the Malvaceae family able to yield a biomass crop through the last two decades. Additionally, the plants have a lot of uses and benefits for instance it can be used as a fodder crop, honey crop, ornamental plant in public gardens. It has favourable features for example fast growing and resistance against the disease and climatic fluctuations, etc. Since Sida is in the beginning phase of domestication, it has a serious disadvantage: the low and slow germination as a big part of wild plants. Due to the expressly low germination percent, the need of seed showing of driller should tenfold 200 thousand seeds/acre instead of 10–20 thousand, which is not available and expensive. Therefore the practical purpose of our research of seed physiology was to increase the seed germination percent in the available, basically wild Sida population. In the first stage of our experiments we examined two factors relating to seed germination percent and seed germination power during our research: the influence of hot water treatment and the effect of exogenous or endogenous infection of seeds. However, in our germination tests, utilizing the scarified seeds with hot water (65, 80 and 95 °C), from 29.3% to 46% germinated from those samples, which were collected from the population of S. hermaphrodita in Debrecen. The average germination for all season was 5–10% without treatment and rinsed using hot water up to almost 50%. When applying physically scarified use, the oldest seeds showed the best germination (46%) after the hot water operation in spite of the previous studies. We discovered that there is a close relationship between the collecting time of the seeds and the ration of seed infections, as well as germination percentage. Thus, the 2009 season was the most favourable in case of contamination (control: 17.3% and 80 °C treatment: 0%) as well as germination percent. It could be concluded that the best season for our findings was 2009 due to autumn harvest of Sida seeds. In our opinion, the autumn harvesting should be the best time to overcome the problem of the low germination and high infection percentage. We also discovered that apparently there is a close relationship between the seed fresh weight or water uptake capability and the percentage of infection. Following these recognitions, we modified our technique in such a way that we fractionated the seeds based on their fresh weight / or relative density before we carried out the treatment. When we filtered the floating seeds on the surface of water, the hot water treatment was performed considerably better on the sunk seeds after separation. Therefore by this special priming process, we were able to reach 80% germination capacity of Virgina mallow seeds under laboratory conditions (26 °C without illumination).
