  • This study aim to investigation the surface ground movement when bored tunnel in soft soil. The monitoring data of ground surface settlements obtained from the case study with implementation project.The gathered information demonstrate that grouting volume and support pressure at drill face significantly affects the settlements of surface induced by bored tunnel. In a case study in HCM Metroline 1,the ground surface settlement was 1 mm to 20 mm caused by the second tunnel (WB tunnel) passing after the EB tunnel construction with smaller ettlement.The combined method for empirical formulation has been used to ground surface settlement of tunnel. It was found that the ground surface s...

  • The Build-Operate-Transfer (BOT) scheme is considered as an attractive means by the Vietnamese government to develop new infrastructure projects. They were started to widely carried out from 2011 and it is predicted to continuously increase in the future. The toll price of BOT road given by investor is set under the ceiling price that is regulated in Circular of Ministry of Transport. It can be seen that most of BOT toll road projects have applied charge that are nearly equal to the given ceiling prices. Nevertheless, the ceiling price at this Circular did not consider the scale of road, as well as did not take into account of travelers’ willingness to pay to toll price. There...

  • 2D materials have attracted significant research interest due to their excellent characteristics. Borophene, a new member of the 2D material family, was proven that it has a unique structure and promising properties by both empirical and theoretical studies. In this study, the adsorption configuration, adsorption energy of toxic gas molecules (CO, NO, CO2, NH3, and NO2) on 12 – borophene was investigated by first – principle calculations using three van der Waals correlation functionals: revPBE-vdW, optPBE-vdW, and vdW-DF2. The most stable configurations and diffusion possibilities of the gas molecules on the 12 – borophene surface were determined visually by using Computati...

  • This study aims to measure Vietnamese instant oats packaging and its influences on Vietnamese consumer’s buying intention. A quantitative research was conducted using an online survey to collect primary data for hypothesis testing. The questionnaire was transferred successfully to 147 respondents. The findings indicated the positive relationship between packaging elements (i.e. graphic, structural and verbal attributes) and consumer purchase intention based on the literature reviews and data analysis discussed precisely in this research. Additionally, the moderation role of involvement level to the interaction of visual elements and purchase intention was also proved in this paper. Th...

  • Every year, millions of pain relief drugs prescriptions are written, and many of them are opioids. Opioids are among the most strong pain relief in clinical use, but their analgesic effect is accompanied with many serious adverse effects, such as constipation, nausea, vomiting, respiratory depression, and addiction. Opioids overdose has been resposible for thousands of deaths every year. These severe issues have been the driving force behind the development new effective painkillers which create less side effects. Opioids creates their effects mainly by binding to mu-opioid receptors (μOR). They are considered as unbiased μOR ligands which non-selectively activate μOR in both...

  • The Metal – Insulator – Metal (MIM) nanocups structure on glass substrate and in water were fabricated by chemical method and sputtering, studied by transmittance properties. The morphology of the sample was studied by Scanning Electron Microscope, and transmittance properties were studies by UV-Vis-NIR, and simulated by Finite Difference Time Domain (FDTD) method. The result showed that MIM nanocups have surface plasmon resonance (SPR) and localize surface plasmon resonance (LSPR) phenomena, that depend on size of Polystyrene (PS) and thickness of metal and insulator layers. The purpose of this thesis is: Deposit monolayer PS nanoparticles on glass substrate ; Fabrication MIM ...

  • Similar to many other developing cities, Hanoi, the capital city of Vietnam, has also faced many serious problems caused by spontaneous urban development and massive private vehicles. As a part of solutions, public transportation systems in Hanoi were paid attention to be invested and developed. However, Public transportation meets only partially the travelling demand of urban people. Even recent years, the productivity of buses in Hanoi tends to be restrain and even going down in some years. Therefore, how to encourage and attract people to use public transportation modes is a more and more urgent topic. This research focuses on a key factor which greatly influences the use of transi...
