Modifying the Mn doping ratio alters the MoS₂ structure, though X-ray diffraction confirms all samples show interlayer-expanded structure. Mn-MoS2-20 shows a significantly improved specific capacity of 170 mAh/g at 0.1 A/g, exceeding that of undoped MoS₂. Furthermore, Mn doping enhances the rate performance of MoS2. While cycling stability at 0.5 A/g and 2 A/g improves with Mn doping, capacity still fades, indicating further improvements in structural stability are needed.

In many countries, particularly in low- and middle-income countries, encouraging the mode shift from private vehicles to PT as well as retaining the current PT users are a challenge. One reason can be the lack of understanding about the aspects of PT services that affect the behavioural intention of users. This study reviews a growing body of peer-reviewed literature examining factors affecting the loyalty intention of PT users and factors influencing the intention to use of non-users. The methodological approach adopted to investigate these factors is also reviewed. The findings are very useful not only for authorities to develop comprehensive strategies aimed at enhancing PT ridership but also for scholars to extend key insights in this area.","PeriodicalId":497003,"journal":{"name":"The University of Danang - Journal of Science and Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135085907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Internal erosion, which is the migration of soil particles following seepage flow, causes inhomogeneity of the soil properties of the embankment. However, there are very few studies investigating the effects of soil inhomogeneities on the seepage behavior of groundwater within embankment. In this study, small-scale modelling tests were performed under repeated seepage flow histories. As a result, the groundwater table gradually increased in accordance with the number of seepage repetition. Modelling the fluctuation of permeability due to internal erosion following seepage flow was additionally performed using the soil/water/air coupled finite element analysis, and seepage behavior was investigated. In these analyses, the lower permeability of the toe of embankment was shown to possibly cause an increase in upward water pressure.","PeriodicalId":497003,"journal":{"name":"The University of Danang - Journal of Science and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of suffusion damages earthen dams and affects the living environment around these structures. To avoid the effect of suffusion, many previous studies in the literature have investigated physical parameters influencing suffusion triggers or predicted suffusion potential. Yet, the precise impact of physical parameters, namely the inter-coarse void ratio (ICVR), on suffusion susceptibility was not considered. Thus, the crucial objectives of this article are devoted to investigating the effects of ICVR on suffusion susceptibility. The results show that suffusion susceptibility decreases until the minimum value at ICVR is 1.1 before increasing again. In addition, models for erosion prediction were proposed based on two physical parameters: ICVR and grain size distribution, which are easily determined in the laboratory.","PeriodicalId":497003,"journal":{"name":"The University of Danang - Journal of Science and Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Griffin and Neal’s [1] safety climate model was used to point out the link between safety climate and safety knowledge and safety compliance; the effect of safety knowledge on safety compliance is also considered as the result of this research. Structural equation modeling (SEM) was used to analyze these relationships among latent constructs. Data was collected from 433 base-app motorcyclists. The results show that the safety knowledge of motorcyclists plays a mediate role in safety compliance and safety climate.

Additionally, difficulties in sieving and quality control have led to the disposal of dredged soil in construction sites. The research aims to enhance the practical use of CLSM as a foundation for rural roads in the Mekong Delta by incorporating dredged soil and mineral additives (6% silica fume, 25% bottom ash) under various curing conditions, including normal, acidic, and salted environments. The study assesses CLSM strength through flowability, setting time, and unconfined compressive strength tests. Findings highlight the significant influence of curing conditions on both early and 28-day CLSM strength, with harsh environments compromising cement hydration. Optimizing dredged soil content and mineral components can bolster CLSM strength and promote sustainable use of dredged soil in construction.","PeriodicalId":497003,"journal":{"name":"The University of Danang - Journal of Science and Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
