GIS-based numerical simulation of Amamioshima debris flow in Japan

Jian WU, Guangqi CHEN, Lu ZHENG, Yingbin ZHANG

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 2,   Pages 206-214 doi: 10.1007/s11709-013-0198-6

Abstract: Debris flow is a rapid flow which could lead to severe flooding with catastrophic consequences such as damage to properties and loss of human lives. It is important to study the movement of debris flow. Since during a debris flow process, the erosion and deposition processes are important, the no entrainment assumption is not acceptable. In this study, first we considered the debris flow as equivalent fluid and adopted the depth-averaged govern equations to simulate the movements and evolution of river bed. Secondly, the set of partial differential equations was solved numerically by means of explicit staggered leap-frog scheme that is accurate in space and time. The grid of difference scheme was derived from GIS raster data. Then the simulation results can be displayed by GIS and easily used to form the hazard maps. Finally, the numerical model coupled with GIS is applied to simulate the debris flow occurred on Oct. 20th, 2010, in Amamioshima City, Japan. The simulation reproduces the movement, erosion and deposition. The results are shown to be consistent with the field investigation.

A boronic acid-based fluorescent hydrogel for monosaccharide detection

Suying Xu, Adam C. Sedgwick, Souad A. Elfeky, Wenbo Chen, Ashley S. Jones, George T. Williams, A.Bull, John S. Fossey, Tony D. James

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 112-116 doi: 10.1007/s11705-019-1812-5

Abstract: A boronic acid-based anthracene fluorescent probe was functionalised with an acrylamide unit to incorporate into a hydrogel system for monosaccharide detection In solution, the fluorescent probe displayed a strong fluorescence turn-on response upon exposure to fructose, and an expected trend in apparent binding constants, as judged by a fluorescence response where D-fructose>D-galactose>D-mannose>D-glucose. The hydrogel incorporating the boronic acid monomer demonstrated the ability to detect monosaccharides by fluorescence with the same overall trend as the monomer in solution with the addition of D-fructose resulting in a 10-fold enhancement (≤0.25 mol/L).

Fatigue crack initiation of magnesium alloys under elastic stress amplitudes: A review

XU, S. D. WANG, E. H. HAN

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 1,   Pages 113-127 doi: 10.1007/s11465-018-0482-1

Abstract: The most advantageous property of magnesium (Mg) alloys is their density, which is lower compared with traditional metallic materials. Mg alloys, considered the lightest metallic structural material among others, have great potential for applications as secondary load components in the transportation and aerospace industries. The fatigue evaluation of Mg alloys under elastic stress amplitudes is very important in ensuring their service safety and reliability. Given their hexagonal close packed structure, the fatigue crack initiation of Mg and its alloys is closely related to the deformation mechanisms of twinning and basal slips. However, for Mg alloys with shrinkage porosities and inclusions, fatigue cracks will preferentially initiate at these defects, remarkably reducing the fatigue lifetime. In this paper, some fundamental aspects about the fatigue crack initiation mechanisms of Mg alloys are reviewed, including the 3 followings: 1) Fatigue crack initiation of as-cast Mg alloys, 2) influence of microstructure on fatigue crack initiation of wrought Mg alloys, and 3) the effect of heat treatment on fatigue initiation mechanisms. Moreover, some unresolved issues and future target on the fatigue crack initiation mechanism of Mg alloys are also described.

Uncovering CO2 emission drivers under regional industrial transfer in China’s Yangtze River

Huijuan JIANG, Yong GENG, Xu TIAN, Xi ZHANG, Wei CHEN, Ziyan GAO

Frontiers in Energy 2021, Volume 15, Issue 2,   Pages 292-307 doi: 10.1007/s11708-020-0706-z

Abstract: With the relocation of heavy industries moving from downstream region to upstream and midstream regions in the Yangtze River Economic Belt (YREB), it is critical to encourage coordinated low carbon development in different regions within the YREB. This paper uncovers the evolution of CO emissions in different regions within the YREB for the period of 2000–2017. It decomposes regional CO emission changes using the temporal and cross-regional three-layer logarithmic mean Divisia index (LMDI) method. Besides, it decomposes industrial CO emission changes using the temporal two-layer LMDI method. The research results show that economic growth is the major driver for regional CO emission disparities. The mitigation drivers, such as energy intensity and energy structure, lead to a more decreased CO emission in the downstream region than in the upstream and midstream regions. In addition, it proposes several policy recommendations based upon the local realities, including improving energy efficiency, optimizing energy structure, promoting advanced technologies and equipment transfers, and coordinating the development in the upstream, midstream and downstream regions within the YREB.

Keywords： CO2 emission     multi-layer LMDI decomposition     industrial transfer     governance
