A preliminary analysis and discussion of the condominium building collapse in surfside, Florida, US,

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5,   Pages 1097-1110 doi: 10.1007/s11709-021-0766-0

Abstract: On June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered a sudden partial collapse. This study analyzed the overall performance and key components of the collapsed building based on the building design codes (ACI-318 and GB 50010). Punching shear and post-punching performances of typical slab-column joints are also studied through the refined finite element analysis. The collapse process was simulated and visualized using a physics engine. By way of these analyses, weak design points of the collapsed building are highlighted. The differences between the reinforcement detailing of the collapsed building and the requirements of the current Chinese code are discussed, together with a comparison of the punching shear and post-punching performances. The simulated collapse procedure and debris distribution are compared with the actual collapse scenes.

Keywords： progressive collapse     flat plate     simulation     punching

Effects of Decoction on plasma proteome in cirrhosis: preliminary experimental study with rats

LIU Jie, WANG Jiyao, WEI Liming, LU Ye, Jin Hong

Frontiers of Medicine 2008, Volume 2, Issue 1,   Pages 39-44 doi: 10.1007/s11684-008-0008-z

Abstract: The aim of this paper is to study the effects of Decoction on the plasma proteome in cirrhotic rats. Twenty-six male Sprague-Dawley (SD) rats were randomly divided into three groups: cirrhotic model group ( = 10), treated with CCl (CCl/olive oil: v/v = 1:1); Decoction intervention group ( = 10), treated with CCl+ Decoction; and normal control group ( = 6), treated with olive oil only. After 8 weeks, blood samples were collected from the inferior vena cava to undergo bi-dimensional electrophoresis (2DE) and analysis by PDQuest 7.3 software. Differential protein spots were cut, enzyme hydrolysis was conducted, and peptide fragments extracted from the mixture underwent mass spectrometry (MS) with MALDI-TOF-TOF-MS. The liver fibrogenesis was assessed using a digital image analysis instrument of Masson’s trichrome stained sections. The fibrosis area of the Decoction was (8.9 ± 3.7)%, significantly smaller than that of the cirrhotic model group [(12.4 ± 4.7)%, < 0.05]. Ten markedly changed protein spots were identified by MALDI-TOF-TOF-MS. Eight of the 10 proteins, including plasma glutathione peroxidase, plasma glutathione peroxidase precursor, prealbumin, haptoglobin, apolipoprotein A-IV precursor, complement C4, inter-alpha-inhibitor H4 heavy chain, and serine/threonine-protein kinase microtubule-affinity regulating kinase 1 (MARK1) were expressed very lowly in the cirrhotic model group while they were expressed highly in the Decoction group. The expression of liver regeneration-related protein LRRG03 and vimentin increased in the cirrhotic model group, and reduced in the Decoction group. Some proteins related to oxidative stress, cell proliferation and transformation have changed in the plasma of cirrhosis induced by CCl. Decoction promotes protein synthesis and plays an anti-fibrotic role by anti-oxidation and accommodation of cell proliferation and transformation.

Capacity estimation and preliminary strategy for reducing the release of dioxins in China

YU Gang, ZHANG Qing, HUANG Jun, CAI Zhenxiao, SUI Qian

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 13-17 doi: 10.1007/s11783-007-0002-8

Abstract: As a party of the Stockholm Convention on Persistent Organic Pollutants, China must submit its national implementation plan (NIP) for this convention. The strategy and action plan for reducing the release of dioxins in China are the most important components of the NIP. Three problems are key points for developing such strategy and action plan what are the key sources for applying the best available technology/best environmental practice (BAT/BEP) to reduce the release of dioxins? How about the capacity for reducing the dioxins release from the key sources? Where are the areas of priority for applying BAT/BEP? This paper shows the efforts towards the solution of these problems. The list of key sources covering about half of the total dioxins release was determined considering four criteria. The capacity of key sources were estimated based on the difference between the emission factor corresponding to the actual situation in 2004 and that corresponding to the scenario that all key sources have been applied BAT/BEP to reduce the dioxins release. The priority analysis using the geographical information system (GIS) tool has revealed that eastern provinces should be of high priority in the future reduction activities of dioxins release in China.
