  • 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...

Ride-hailing is the act of requesting a ride from a private passenger vehicle by an app on a smartphone. RHS has appeared in Vietnam from 2014, however, it has spread rapidly and affect significantly to Vietnam transport market and travel habit of people. Until now, there has been still no completed regulation for the operation of RHS in Vietnam. RHS has caused big controversy with the domestic taxi industry, traditional taxi companies claim that RHS is no different from taxis, and that ride-hailing companies (RHCs) should be held to the same opera...

  • The real lattice is not perfect but contains many types of defects, which can be referred to as vacancy, dislocation, or grain boundary. While vacancy is well known as a typical case of point defect and also a simple case which we can consider. Study about the vacancy case in BCC structure of iron will help us understand clearly about the role and the effects of vacancy to the diffusion and clustering of carbon in iron matrix. The cause of the interaction between carbon and metals has a tremendous scientific and technological interest which has essential effects on the yield stress and the subconsequent mechanical properties and also a broad range of implications in the scope of...

  • In this thesis, I have developed a low-cost, simple and one-step approach to synthesize MnO2/graphene composite with enhanced electrochemical performance. MnO2/graphene composite was prepared via a plasma-assisted electrochemical exfoliation method with an electrolyte solution made of KMnO4 precursor. MnO2/graphene composites were characterized by SEM, TEM, XRD, Raman, XPS and were employed for the examination of electrochemical behaviors. MnO2/graphene composite displayed the specific capacitance of 217.0 F g−1 at current density of 2 A g-1, which is approximately three times higher than those of pristine graphene (47.0 F g−1). Interestingly, the capacitance retention was hig...

  • 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...
