We describe a new species of Rhacophorus based on two adult specimens collected from Hoa Binh Province, northern Vietnam. Rhacophorus hoabinhensis sp. nov. is distinguishable from its congeners on the basis of a combination of the following morphological characters： size small （SVL 31.1-32.5 mm in males）; head slightly longer than wide; vomerine teeth absent; snout short （SNL/SVL 0.16）; dorsal skin smooth; forearm and tarsus with dermal fringes; dermal appendage at vent present; webbing formula on fingers I12/3-12/3II1-2III1-1IV and on toes I3/4-1II1/2- IIII1/2-1IVI-1/2V; dorsal surface grey yellow with brown spots; lower jaw region dark grey, throat, chest and belly cream; anterior and posterior thighs, as well as ventral surface of tibia orange. The interspecific uncorrected genetic distances （16S rRNA gene） between the new species from Hoa Binh and other analyzed congeners varied from 9.8% to 17.4%. In the phylogenetic analyses, the new species revealed to be a representative of Rhacophorus and was nested within the R. hoanglienensis-orlovi species group.

Objective:To assess levels of HBs Ab amongst infants who received hepatitis B vaccine in the Expanded Program on Immunization in ***:A cross-sectional study was carried out at 16 community health centers from February 2016 to July *** infants were tested for HBs Ab and HBs *** questionnaires were used to collect relevant information about the demographics of the parents/caregivers and their infants after physical ***:A total of 199 eligible infants were selected with a mean age of(17.3±4.5)*** antibody levels with HBs Ab≥10 m IU/m L were detected in 68.3%of *** these,antibody levels from 10 to 99 m IU/m L were 48.5%of those tested and antibody levels≥100 ml U/m L were recorded as 51.5%.No cases were recorded of being infected with hepatitis B *** rate of positive HBs Ab level in those who were not wasting and≥18 months old was less than that among those who were<18 months old(OR 0.49,95%CI:0.26-0.92,P<0.05)while the infants with wasting and<18 months were less likely to be positive HBs Ab than those who were not wasting and of the same age group(OR 0.15,95%CI:0.04-0.55,P<0.05).Conclusions:Seroprotection against hepatitis B virus was low in the infants tested(at 68.3%),which suggests that the hepatitis B vaccine should be administered with one additional dose for infants between 12 and 24 months of age,particularly those with wasting.

This paper for first time proposes an isogeometric analysis (IGA) for free vibration response of bi-directional functionally graded (BDFG) rectangular plates in the fluid medium. Material properties of the BDFG plate change in both the thickness and length directions via power-law distributions and Mori-Tanaka model. The governing equation of motion of BDFG plate in the fluid-plate system is formulated basing on Hamilton's principle and the refined quasi three-dimensional (3D) plate theory with improved function f(z). The fluid velocity potential is derived from the boundary conditions of the fluid-plate system and is used to determine the added mass. The discrete system of equations is derived from the Galerkin weak form and numerically analyzed by IGA. The accuracy and reliability of the proposed solutions are verified by comparing the obtained results with those published in the literature. Moreover, the effects of the various parameters such as the interaction boundary condition, geometric parameter, submerged depth of plate, fluid density, fluid level, and the material volume control coefficients on the free vibration behavior of BDFG plate in the fluid medium are investigated in detail. Some major findings regarding the numerical results are withdrawn in conclusions.

The Vietnam-Europe relations can be traced back to four centuries ago when the first European missionary arrived in the country. However, this relationship has gone a long history with up and down events, partly because of the misunderstanding and lack of information that influenced much on their cooperation. The main objective of the paper is to analyze the development of European Studies in Vietnam from historical perspective using the first hand information collected in Vietnam, and argue that in order to promote the European Union (EU)-Vietnam relations, European studies must be a priority in policy agenda of both sides. The paper concluded that European studies should be seen as an efficient measure to attract more and more students, and through which to promote image and understanding among people, and believed that there will be no doubt about the future of the EU-Vietnam relationship.
