Journal of geographical Sciences 2025年第2期35卷 382-408页

The perfection of the cross-border regional innovation system of the Pearl River Delta(PRD) and Hong Kong remarkably underpins the construction of the guangdong-Hong Kong-Macao greater Bay Area(gBA) towards an international technological innovation *** paper focuses on the relational characteristics of the usage of technological innovation functions and elements, including labor force, technology, and producer services from Hong Kong by high-technology firms in the PRD, and probes into the influencing factors by integrating the objective perspective on the impact of firm-level socioeconomic attributes and subjective perspective on the open interpretations on the reasons by using or not using technological innovation functions and elements from Hong Kong by various stakeholders in high-technology domains in the PRD. Key research findings are fourfold. First, Hong Kong's technological innovation functions primarily ride on its institutional advantages under the “One Country, Two Systems” framework to empower high-technology firms in the PRD by expanding their international market, international business operation, and financing, but cross-border investment and entrepreneurship has retrieved to a relatively marginalized position. The degree of supply-demand relations of producer services is the highest, followed by labor force and ***, Hong Kong-invested, large-sized, and long-standing high-technology firms in the PRD are more inclined to use technological innovation elements from Hong Kong, while domestic,small-and-medium-sized, and start-up high-technology firms in the PRD are in turn, gradually unhooked from the supply of technological innovation elements from Hong Kong. Third, Hong Kong enjoys both advantages and disadvantages in supplying labor forces, technologies, and producer services to high-technology firms in the PRD, with advantages in competitiveness,international linkages and visions, and disadvantages in high cost, lack of more profoun

Characterization of the archaeal community fouling a membrane bioreactor

Journal of Environmental Sciences 2015年第3期27卷 115-123页

作者： Jinxue Luo Jinsong Zhang Xiaohui Tan Diane McDougald guoqiang Zhuang anthony.g.fane Staffan Kjelleberg Yehuda Cohen Scott A.Rice Key Laboratory of Environmental Biotechnology Research Center for Eco-Environmental Sciences Chinese Academy of Sciences School of Biological Sciences Nanyang Technological University Advanced Environmental Biotechnology Centre Nanyang Environment and Water Research Institute Nanyang Technological University Singapore Membrane Technology Centre Nanyang Environment and Water Research Institute Nanyang Technological University Centre for Marine Bio-Innovation School of Biotechnology and Biomolecular Sciences The University of New South Wales Singapore Centre on Environmental Life Sciences Engineering Nanyang Technological University

Biofilm formation, one of the primary causes of biofouling, results in reduced membrane flux or increased transmembrane pressure and thus represents a major impediment to the wider implementation of membrane bioreactor （MBR） technologies for water purification. Most studies have focused on the role of bacteria in membrane fouling as they are the most dominant and best studied organisms present in the MBR. In contrast, there is limited information on the role of the archaeal community in biofilm formation in MBRs. This study investigated the composition of the archaeal community during the process of biofouling in an MBR. The archaeal community was observed to have lower richness and diversity in the biofilm than the sludge during the establishment ofbiofilms at low transmembrane pressure （TMP）. Clustering of the communities based on the Bray-Curtis similarity matrix indicated that a subset of the sludge archaeal community formed the initial biofilms. The archaeal community in the biofilm was mainly composed of Thermoprotei, Thermoplasmata, Thermococci, Methanopyri, Methanomicrobia and Halobacteria. Among them, the Thermoprotei and Thermoplasmata were present at higher relative proportions in the biofilms than they were in the sludge. Additionally, the Thermoprotei, Thermoplasmata and Thermococci were the dominant organisms detected in the initial biofilms at low TMP, while as the TMP increased, the Methanopyri, Methanomicrobia, Aciduliprofundum and Halobacteria were present at higher abundances in the biofilms at high TMP.

Homeostatic responses to amino acid insufficiency

Animal Nutrition 2015年第3期1卷 135-137页

作者： Tracy g.anthony Department of Nutritional Sciences Rutgers University

This article provides a brief overview describing how two key signaling pathways, namely the integrated stress response and the mammalian target of rapamycin complex 1, work together to facilitate cellular adaptation to dietary amino acid insufficiency. A deeper understanding of these mechanisms is leading to identification of novel targets which aid in disease treatments, improve stress recovery and increase health span through slowed aging and enhanced metabolic fitness.

以纯水为介质，用直接接触式膜蒸馏测定了材料或性能参数不同的三种多孔疏水膜在不同温度下的渗透通量。根据测量结果计算出了各种膜在不同温度下的渗透系数，发现渗透系数均随着温度的升高而升高；这一结果说明Poiseuille流动在跨膜传质中起着非常重要的作用。据此提出了Knudsen扩散-Poiseuille流动两参数跨膜传质模型，即TPKPT模型。用此模型拟合实验数据，得到了三种实验用膜的模型参数。用这些模型参数计算膜在不同温度下的渗透系数，其值与实验测量值吻合较好，说明TPKPT模型能较好地描述膜蒸馏的跨膜传质过程。
