Cohesion variation during instability evolution of disaster medium in mud inrush of mountain tunnel

Teng Yang, Qing-song Zhang, Xiao Zhang, Xiang-hui Li, more

Journal of Mountain Science > 2019 > 16 > 11 > 2519-2531

Mud inrush in mountain tunnel is an independent geological hazard type different from water inrush, landslide and debris flow. The intrinsic factor of mud inrush is the instability failure of disaster medium. Its essence is that when the cohesion decreases gradually with the increase of void ratio to the point where the movement of soil particles cannot be restricted, soil particles and groundwater...

Detection and treatment of water inflow in karst tunnel: A case study in Daba tunnel

Xiang-hui Li, Qing-song Zhang, Xiao Zhang, Xiong-dong Lan, more

Journal of Mountain Science > 2018 > 15 > 7 > 1585-1596

In a karst tunnel, fissures or cracks that are filled with weathered materials are a type of potential water outlet as they are easily triggered and converted into groundwater outlets under the influence of high groundwater pressure. A terrible water inrush caused by potential water outlets can seriously hinder the project construction. Potential water outlets and water sources that surrounding the...

Fabrication of Organic Hec Nanocomposites Modified with Lysine as a Potential Adsorbent for Bilirubin Removal

Chan Li, Wen Zhang, Ning Yang, Qing Song Zhang

Applied Biochemistry and Biotechnology > 2019 > 188 > 3 > 769-786

As one of the typical phyllosilicate clays, hectorite (Hec) has some excellent characteristics and has been greatly applied in adsorption field for the removal of dye, endotoxin, etc. In this study, organic Hec nanocomposites modified with l-Lysine (Lys/Hec NCs) were prepared via solution intercalation method for BR removal. The effects of ionic strength, pH values, initial concentration of BR, and...

Erythropoietin promoted the proliferation of hepatocellular carcinoma through hypoxia induced translocation of its specific receptor

Shuo Miao, Su-Mei Wang, Xue Cheng, Yao-Feng Li, more

Cancer Cell International > 2017 > 17 > 1 > 1-14

Background Erythropoietin (EPO) is a hypoxia-inducible stimulator of erythropoiesis. Besides its traditional application in anemia therapy, it offers an effective treatment in the cancer patients, especially those who receive chemotherapy. Several reports indicated that it could promote the tumor cell proliferation through its specific receptor (EPOR). Unfortunately, the role of EPO/EPOR in hepatocellular...

Grouting mechanism of quick setting slurry in rock fissure with consideration of viscosity variation with space

Qing-song Zhang, Lian-zhen Zhang, Ren-tai Liu, Shu-cai Li, more

Tunnelling and Underground Space Technology > 2017 > 70 > C > 262-273

Quick setting slurry is commonly used in rock fissure grouting projects due to short gel time, high early strength and high retention rate in groundwater. Generally, quick setting slurry is composed by grout material and quick set reagent, and can be injected by using two-shot injection systems, which mixing two components inside or outside injection hole. Resulting from two-shot injection style and...

Mathematical modeling of air bubbler systems

Qing Song Zhang, Li Xu

2015 7th International Conference on Modelling, Identification and Control (ICMIC) > 1 - 4

2015 7th International Conference on Modelling, Identification and Control (ICMIC)

The use of air bubbler systems to improve the Marine environment is a technique that has been applied in a variety of situations with varying degrees of success. In 2005, the research done by Liang et al was regarded as the beginning of the closed air bubbler systems (injecting gas underwater in the vertical pipe). The analysis was a steady-state evaluation of the lifting efficiency of ocean water...

Sulfuric acid leaching kinetics of South African chromite

Qing Zhao, Cheng-jun Liu, Pei-yang Shi, Bo Zhang, more

International Journal of Minerals, Metallurgy, and Materials > 2015 > 22 > 3 > 233-240

The sulfuric acid leaching kinetics of South African chromite was investigated. The negative influence of a solid product layer constituted of a silicon-rich phase and chromium-rich sulfate was eliminated by crushing the chromite and by selecting proper leaching conditions. The dimensionless change in specific surface area and the conversion rate of the chromite were observed to exhibit a proportional...

A closed-loop sidelobe cancellation method based on iteration by using an analog and digital mixed system

Qing-song Zhang, Hui-yong Li, Zi-shu He

2013 International Conference on Communications, Circuits and Systems (ICCCAS) > 2 > 283 - 286

2013 International Conference on Communications, Circuits and Systems (ICCCAS)

Sidelobe cancellation is an effective beamforming method of interference suppression. In this paper, an analog and digital mixed system for sidelobe cancellation is introduced firstly. Then, a closed-loop sidelobe cancellation method based on iteration is proposed by using the previous system. The working principles of this method are derived and the working processes of this method are given in detail...

Effects of nano TiO₂ on the light reflectivity, morphology, and rheological behavior of LLDPE‐glass bead composites

Qing Liu, Bing Meng, Qing‐Song Zhang, Wei Yang, more

Journal of Applied Polymer Science > 125 > S1 > E644 - E650

Heat‐shield composites based on linear low density polyethylene (LLDPE) filled with micro‐hollow glass beads (HGB) and TiO₂ nanoparticles were prepared through melt compounding. Two kinds of LLDPE were used as the matrix of these composites with a fixed weight ratio of 60 : 40. HGB loadings were fixed at 28 wt % of LLDPE matrix while TiO₂ content varied between 8 and 28 wt % of LLDPE matrix. Interestingly,...

Concrete based on the natural environment of early age cracking sensitivity test

Qing-Song Zhang

2011 International Conference on Remote Sensing, Environment and Transportation Engineering > 5824 - 5827

2011 International Conference on Remote Sensing, Environment and Transportation Engineering (RSETE)

Concrete cracking of cement-based materials has been a hot research field, especially for non-load in recent years due to early cracking of particular concern. This paper describes the simulation of the natural environment during construction, the use of flat crack planes, the air in different time periods were pouring concrete slab cracking, observed and recorded later analysis and evaluation of...
