| 1 | Dynamic Response and Deformation Behavior of Kadui-2 Landslide Influenced by Reservoir Impoundment and Rainfall,Baoxing,China显示文摘This study focuses on the deformation characteristics of Kadui-2 Landslide by the influence of reservoir filling-drawdown and precipitation.A three-year monitoring project was implemented in order to observe the short/long-term deformation.The slide mass experienced consistent deformation with a maximum cumulative displacement of 331.34 cm.Based on the recorded data of reservoir water level and precipitation during this period,a two-dimensional(2-D)finite element model using Geostudio software was set up for deformation simulation under different conditions to understand the real influence of these triggering factors on landslide.The numerical simulation results are in consistent with monitoring field data.Both numerical simulation and field monitoring results exhibit that the maximum deformation occurred at the foreside of slumping mass.The slip surface shows significant creep characteristics decreasing as long-term shear strength reducing gradually.Reservoir water level fluctuation is the primary triggering factor to reactivate the landslide mass and has a negative correlation with deformation rate.Displacement rate increases with the reservoir drawdown and decreases with impoundment rise.Compared with reservoir filling-drawdown operation,rainfall has no significant effect on the slide motion of landslide due to limited penetration from the ground surface. | Muhammad Kamran Xiewen Hu Muhammad Awais Hussain Muhammad Sanaullah Randa Ali Kun He | 2023 | Journal of Earth Science2023，34，3： | 1 |
| 2 | Functional activity of the rectum:A conduit organ or a storage organ or both?显示文摘瞄准:为了调查直肠的扩张的度是否能定义直肠,作为一根水管或水库工作。方法:到 2 的直肠、肛门的压力的反应直肠的汽球扩张打字,快速的多卷、慢的渐渐的膨胀,在 21 个健康志愿者被记录(12 个男人, 9 个女人,变老 41.7 +/- 10.6 年) 。测试在迫切感觉上与括约肌 squeeze 被重复。结果:快速的多卷的直肠的扩张导致了重要直肠的压力增加(P <
0.001 ) ,肛门压力衰落(P <
0.05 ) 并且汽球逐出。这些题目感到了迫切感觉但是没感到第一直肠的感觉。在迫切感觉上,肛门引起重要直肠的压力减少的 squeeze (P <
0.001 ) 并且紧急消失。慢增长的直肠的充满与一个“音调”拉了 rectometrogram 在直肠的充满期间代表渐渐的直肠的压力增加的手足,和“撤退手足”在汽球逐出期间代表锋利的压力增加。曲线记录了第一直肠的感觉和迫切感觉。结论:直肠显然有二功能:交通(水管) 和存储,两个都取决于直肠的充满的度。如果直肠收到的烘便的材料是小的,它在直肠被存储直到大体积被到达那个罐头影响足够的直肠的扩张的度开始澄清反射。直肠的扩张直接唤起的大体积书籍的右页有产生澄清的肛门禁止的反射。 | Ahmed Shafik Randa M Mostafa Ismail Shafik Olfat EI-Sibai Ali A Shafik | 2006 | World Journal of Gastroenterology2006，12，28： | 1 |
| 3 | Effects of Carpobrotus edulis Extract on Oxidative Stress and 158N Oligodendrocyte Death显示文摘Objective Age-related diseases, including neurodegenerative diseases, are associated with oxidative stress and lipid peroxidation, and increase the levels of cholesterol auto-oxidation products such as 7β-hydroxycholesterol(7β-OHC). Thus, it is imperative to identify agents that can prevent 7β-OHC-induced side-effects. Methods We evaluated the potential protective effects of Carpobrotus edulis ethanol-water extract(EWe) on murine oligodendrocytes(158 N) cultured in the absence or presence of 7β-OHC(20 μg/mL, 24 h). The cells were incubated with EWe(20-200 μg/mL) 2 h before 7β-OHC treatment. Mitochondrial activity and cell growth were evaluated with the MTT assay. Photometric methods were used to analyze antioxidant enzyme [catalase(CAT) and glutathione peroxidase(GPx)] activities and the generation of lipid and protein oxidation products [malondialdehyde(MDA), conjugated diene(CD), and carbonylated proteins(CPs)]. Results Treatment with 7β-OHC induced cell death and oxidative stress(reflected by alteration in CAT and SOD activities). Overproduction of lipid peroxidation products(MDA and CDs) and CPs was also reported. The cytotoxic effects associated with 7β-OHC were attenuated by 160 μg/mL of EWe of C. edulis. Cell death induced by 7β-OHC treatment was ameliorated, GPx and CAT activities were restored to normal, and MDA, CD, and CP levels were reduced following C. edulis extract treatment. Conclusion These data demonstrate the protective activities of C. edulis EWe against 7β-OHC-induced disequilibrium in the redox status of 158 N cells, indicative of the potential role of this plant extract in the prevention of neurodegenerative diseases. | Amira Zarrouk Mohammed Ali Smach Jawhar Hafsa Randa Sghaier Hatem majdoub Mohammed Hammami Bassem Charfeddine | 2019 | Biomedical and Environmental Sciences2019，32，4： | 1 |
| 4 | Analysis of BrainMRI: AI-Assisted Healthcare Framework for the Smart Cities显示文摘The use of intelligent machines to work and react like humans is vital in emerging smart cities.Computer-aided analysis of complex and huge MRI(Mag-netic Resonance Imaging)scans is very important in healthcare applications.Among AI(Artificial Intelligence)driven healthcare applications,tumor detection is one of the contemporary researchfields that have become attractive to research-ers.There are several modalities of imaging performed on the brain for the pur-pose of tumor detection.This paper offers a deep learning approach for detecting brain tumors from MR(Magnetic Resonance)images based on changes in the division of the training and testing data and the structure of the CNN(Convolu-tional Neural Network)layers.The proposed approach is carried out on a brain tumor dataset from the National Centre of Image-Guided Therapy,including about 4700 MRI images of ten brain tumor cases with both normal and abnormal states.The dataset is divided into test,and train subsets with a ratio of the training set to the validation set of 70:30.The main contribution of this paper is introdu-cing an optimum deep learning structure of CNN layers.The simulation results are obtained for 50 epochs in the training phase.The simulation results reveal that the optimum CNN architecture consists of four layers. | Walid El-Shafai Randa Ali Ahmed Sedik Taha El-Sayed Taha Mohammed Abd-Elnaby Fathi E.Abd El-Samie | 2023 | Intelligent Automation & Soft Computing2023，，2： | 0 |
