Little is known about how claims for urban citizenship in transitional states influence urban governance. Advancing the literature, this article draws on empirical research about a tree-felling dispute in Hanoi. It argues that social media are transforming how citizens project power over city officials. Interviews showed how a combination of street protests and criticism on social media disrupted state expectations about how citizens should behave. This opened political space that enabled citizens to voice their concerns. Although officials reacted emotionally to moral coercion, they refused to engage with deliberative claims for urban citizenship and the right to participate in governance. The article concludes that social media provide a space where urban citizenship can evolve, disseminate and eventually influence the state.

Adenoviral conjunctivitis is a common epidemic worldwide. In Vietnam, up to 80,000 patients are infected with adenoviral conjunctivitis annually. However, there are few investigations on the pathogenic adenoviruses that cause conjunctivitis. In total, 120 eye‐swab samples were collected from patients with viral conjunctivitis symptoms in Hanoi, Vietnam from 2017 to 2019. Human adenoviruse (HAdV) was detected in 67 samples (55.83%) using polymerase chain reaction amplification of at least one of three HAdV‐specific marker genes (hexon, penton, and fiber). Of the 67 HAdV samples, 46 samples could be analyzed by all three marker genes. DNA sequence analysis and phylogenetic tree building based on the three marker genes from the 46 HAdV samples revealed five different HAdV types associated with conjunctivitis in Hanoi, including HAdV‐3 (4.3%), HAdV‐4 (2.2%), HAdV‐8 (89.1%), HAdV‐37 (2.2%), and a potential recombinant type between types HAdV‐8 and HAdV‐3 (2.2%). This showed that HAdV‐8 was the most common type identified in Hanoi. Complete genome analysis of HAdV‐8 isolated from a Vietnamese patient (VN2017) using Sanger sequencing revealed 34 unique nucleotide changes, indicating that the adenovirus continuously accumulates new mutations. Hence, continuous surveillance of HAdV‐8 changes in Vietnam is necessary in the future.

Proper Orthogonal Decomposition (POD) is based on a space and time decomposition and on the finding of eigenfunctions. It is a technique for recognizing or identifying key dominant features in data sets. The release of high sand concentrated in water induces a flow with particular structures as showed experimentally by Villaret et al. [1]. Two-phase flow simulations with no current were presented by Guillou et al. [2]. The present paper shows the POD-analyses of results of such a simulation with and without current. Two spatio-temporal fields, the solid volume fraction and the solid phase velocity within the sediment release coherent structures are successfully captured by applying Proper Orthogonal Decomposition on numerical simulation results..

Seismic isolation is one of the most efficient techniques to protect structures against earthquakes. Rubber bearings are suitable for low-rise and medium-rise buildings due to its durability and easy fabrication. This paper presents the hori-zontal response of a six-storey base-isolated building using high damping rubber bearings (HDRB) under two ground motions of earthquakes as types I and II in JRA (2002) by finite element analysis. In this analysis, these bearings are mod-elled by the bilinear hysteretic model which is indicated in JRA and AASHTO. Comparison of horizontal response including base shear force and roof level acceleration between the two cases: base-isolated building and fixed-base building is carried out to evaluate the effectiveness of the use of HDRB on the protection of buildings from earthquakes. The numerical results show that the peak value of roof floor acceleration of the fixed-base building is two times higher than that of the base-isolated building, and the floor accelerations depend on the peak values of ground acceleration. In addition, the step-by-step design procedure for deter-mining the size of HDRBs used for buildings is also presented in this paper.
