Determination of Maximum Penetration Depth of Suction Caissons in Sand
Wu Yuqi,LI Dayong,Zhang Yukun,Chen Fuquan 대한토목학회 2018 KSCE Journal of Civil Engineering Vol.22 No.8
The suction caisson is a large top-closed cylindrical steel structure in diameter, short in length and much thinner in skirt wallthickness. The total resistance of the suction caisson during installation consists of the tip resistance and the skirt wall friction. However, since the thickness of the skirt wall is very small, the skirt wall friction may produce additional vertical stress and shearstress in soil at the skirt tip level, and this additional vertical stress and shear stress will contribute to the increase in the skirt tipresistance. At the same time, seepage induced by suction also causes the tip resistance to reduce significantly. A modified slip-linefield is proposed in this study estimating the tip resistance in terms of the slip-line theory. The expression obtaining the minimumsuction to install the suction caisson is also proposed in terms of the force equilibrium. In addition, the critical suction is determinedbased on the mechanism of sand piping. Thus, the maximum penetration depth of the suction caisson can be reached when the criticalsuction equals the minimum suction. Results from calculations of the minimum suction and the maximum penetration depth havebeen proved to be in a good agreement with the measured data.

Anti-domestic violence law: The fight for women’s legal rights in China
Fei Qi,Yuqi Wu,Wang Qi 이화여자대학교 아시아여성학센터 2020 Asian Journal of Women's Studies(AJWS) Vol.26 No.3
In China, the definition of domestic violence is usually limited to direct physical and mental harm to family members. About a quarter of Chinese families have been reportedly affected by domestic violence to different degrees, with most victims being women who have lacked effective legal protection for a long time. In response, Chinese feminists advocated the implementation of the Anti-domestic Violence Law (ADVL). Through judicial reforms, the Supreme Court of China has urged local courts at all levels to establish Family Law Divisions so that they can implement the provisions of ADVL better. However, due to compromises made before it was finalized and the restrictions of the Chinese legal system, its effectiveness is still limited, making it difficult for Chinese female victims of domestic violence to obtain sufficient support from the courts. The process Chinese feminists have undertaken to put forward their ideas regarding this Law has only just begun.

Shear characteristics of the interface between sand and the suction caisson wall play animportant role in determining the friction resistance along the suction caisson wall. In thisstudy, a variable normal load (VNL) reflecting the effects of the penetration depth andinstallation rate of a suction caisson is applied using the torsional interface shear apparatus toexamine the interface shear behavior. Results show that the interface friction coefficientdecreases with the increase of the normal stress and shearing rate until reaching a criticalvalue. When the friction coefficient reaches the critical value, the friction coefficient changeslittle with the increase of normal stress. The variation of the friction coefficient caused by theseepage flow and penetration rate should be considered for calculating the frictional forcealong the caisson wall. Given the same shearing rate, the normalized efficiency parameter ofthe interface under the VNL is higher than that obtained under the CNL. The suctioncalculated based on the test results of this study is in good agreement with that from the Tenbyproject, indicating that our findings are reliable and beneficial to analyze the installationprocess of the suction caisson.

Nosema ceranae, a newly emergent parasite invading western honey bees (Apis mellifera L.), is indicated to threaten honey bee health at both individual and colony levels. However, the efficient and environmentallyfriendly treatments are quite limited at present. To find alternative medicine to control Nosema diseases, the effect of 8 types of herbal extracts against N. ceranae infection were screened under laboratory condition. Of which, 1% Andrographis paniculata (A. paniculata) decoction was found to significantly decrease N. ceranae spore numbers on 7 days post infection (dpi) and 13 dpi. Then, our results further revealed that A. paniculata decoction at doses ranging from 1% to 7% displayed significant efficient inhibition of Nosema spore proliferation and improved the infected bees’ survival rates in a dose-dependent manner. A. paniculata decoction was found to protect the gut tissues of infected workers from damage cause by N. ceranae, which might be due to the regu lation of the expression of certain genes in Wnt and JNK pathways, including armadillo, basket, frizzled2 and groucho. Additionally, our study suggested that A. paniculata decoction performed this Nosema spore-reducing potential over its two monomers, andrographolide and dehydrographolide. Taken together, this work enables us to better understand A. paniculata decoction’s potential to inhibit N. ceranae infection, thus providing a new guidance for developing applicable drugs to control Nosema diseases.

Study on Volatility of Palm Oil Biodiesel/-10 Petrodiesel by Thermogravimetric Analysis Technique
Yongbin Lai,Peng Wang,Xiu Chen,Yinnan Yuan,Junfen Rong,Guang Wu,Yijun Zhou,Lei Zhong,Yuqi Zhang 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.2
Palm methyl ester (PME) was prepared from palm oil through transesterification using NaOH as catalyst. Chemical composition of the PME and -10 petrodiesel (-10PD) was determined by gas chromatography-mass spectrometer (GC-MS). The PME and -10PD were characterized for their fuel properties including density, kinematic viscosity, and flash point, cold filter plugging point, sulfur content, copper strip corrosion and oxidative stability. Volatility was measured by thermogravimetric analysis (TGA). Volatile index was proposed to describe PME/-10PD volatility. A good correlation model was put forward for calculating the PME/-10PD volatility by PME blending ratio. The study showed that PME was mainly composed of long chain fatty acid methyl esters (FAMEs): C14:0-C24:0, C16:1-C22:1, C18:2 and C18:3. -10PD was mainly composed of long chain alkanes: C8-C26. The fuel properties of PME were within the limits prescribed in the GB/T 20828-2007 standards for biodiesel. With respect to -10PD, volatilization of PME was stronger and quicker, but volatilization onset at higher temperature. The volatilization onset temperatures of PME and -10PD were 448.9 and 361.7 K respectively; and the volatile indexes were 1.76E-04 and 3.64E-05 respectively. The PME/-10PD volatility had relation to PME blending ratio. The volatility of B0-B20 was very close to the -10PD. The volatility of B20-B100 was better with increasing the PME blending ratio.
