Tidal Asymmetry Changes in a Shallow Mud Estuary by a Restoration Project

引用

Journal of Ocean University of China 2019年第2期18卷 339-348页

作者： LIANG Huidi KUANG Cuiping GU Jie MA Yue chen kuo LIU Xu College of Civil Engineering Tongji University College of Marine Ecology and Environment Shanghai Ocean University

The tidal asymmetry-induced siltation below tidal barriers is a worldwide problem that restricts regional socio-economic and environmental development. The hydrodynamic processes of the small mud estuary also feature a high uncertainty after estuary restoration measures. In this study, a hydrodynamic model based on the MIKE21 is used to quantify the responses of tidal asymmetry to a two-phase restoration project in Shuanglong Estuary, Bohai Bay, China. According to the numerical modeling results, the tidal flat removal in the upper estuary(first-phase restoration) induces the flood asymmetry switching to the ebb asymmetry in unrestored reach but enhances flood asymmetry in widening restored reach. Although the tidal asymmetry reverts to flood-dominated pattern after full restoration over the estuary, the imbalance between flood and ebb velocities is relieved. A possible net sediment transport pattern based on a comparison of dominant asymmetric current and actual sediment transport period shows net sediments in the upper estuary and inlet transport seaward and landward, respectively, in the first-phase restoration, whereas landward net sediment transport occurs in the whole estuary under the second-phase restoration scenario. Given these results, we assume that a switch from the flood-dominated estuary to ebb-dominated estuary can be caused by redesigning the cross-sectional profile. The quantitative comparison of Lagrangian residual currents also implies that a channel–shoal structure rather than a flat bathymetry can promote the mass transport. Therefore, reshaping the channel–tidal flat system in restoration projects can prevent the sedimentation of the estuary and improve the water environment.

AIM Capsaicin, a pungent ingredient found in red pepper, has long been used in spices, food additives, and drugs. Cell death induced by the binding of capsaidn was examined in a human gastric adenocarcinoma cell line （AGS cells）. METHODS： By using XTT-based cytotoxicity assay, flow cytometry using the TUNEL method, and quantitation of DNA fragmentation, both cell death and DNA fragmentaUon were detected in AGS cells treated with capsaicin. By using Western blotting methods, capsaicin reduced the expression of Bcl-2, the antiapoptotic protein, in AGS cells in a concentration-dependent manner. RESULTS- After incubation of AGS cells with capsaicin for 24 h, cell viability decreased significantly in a dose-dependent manner. After incubation of AGS cells with capsaicin for 24 h, apoptotic bodies also significantly increased, and were again correlated with the dose of capsaicin. When the concentration of capsaicin was 1 mmol/L, the amount of DNA fragments also increased. Similar results were also in the lower traces. CONCLUSION： These results suggest that capsaicin- induced cell death might be via a Bcl-2 sensitive apoptotic pathway. Therefore, capsaicin might induce protection from gastric cancer.

AIM To assessed the effect of liver cirrhosis(LC) on the poorly understood long-term mortality risk after firstever mechanical ventilation(1-MV) for acute respiratory *** All patients in Taiwan given a 1-MV between 1997 and 2013 were identified in Taiwan's Longitudinal Health Insurance Database 2000. Each patient with LC was individually matched, using a propensity-score method, to two patients without LC. The primary outcome was death after a *** A total of 16653 patients were enrolled: 5551 LC-positive (LC^([Pos])) patients, including 1732 with cryptogenic LCs and 11102 LC-negative(LC^([Pos])) controls. LC^([Pos]) patients had more organ failures and were more likely to be admitted to medical department than were LC^([Pos]) controls. LC^([Pos]) patients had a significantly lower survival rate(AHR = 1.38, 95%CI: 1.32-1.44). Moreover, the mortality risk was significantly higher for patients with non-cryptogenic LC than for patients with cryptogenic LC(AHR = 1.43, 95%CI: 1.32-1.54) and patients without LC(AHR = 1.56, 95%CI: 1.32-1.54). However, there was no significant difference between patients with cryptogenic and without LC(HR = 1.05, 95%CI: 0.98-1.12).CONCLUSION LC, especially non-cryptogenic LC, significantly increases the risk of death after a 1-MV.
