Surficial sediment samples along the coastal area of province Thai Binh in Vietnam have been collected and analysed by modified Tessier method for mercury content. The levels these were found range between 0.12–3.79 mg/kg. Elevated concentrations observed some locations close to tidal marshes, large aquaculture productions or low-lying areas. highest level was detected a terrain near productions. majority species all witnessed fraction bound organic matters. predominance this is possibly...
This study performed an experimental investigation of asphalt concrete with and without fiberglass geogrid reinforcement, using specimens in the laboratory situ. A 100kN/m was used. The results showed that flexural strength increased by 24.82%, deformation significantly reduced, elastic modulus did not improve significantly. In addition, Hamburg Wheel Tracker test, reinforced samples had a 7.41%reduced rutting depth. Finally, two segments situ were also tested showing 24.27% structural...
This paper presents an experimental study of rice husk ash-cement-based soil for layers in roadway construction. Rice ash (RHA) used this is a by-product milling. In work, twelve proportion mixes were with varying quantities RHA (0-30%), and Portland cement blended amounts 4, 6, 8%. The specimens prepared by the Proctor mould method, conditioned at room temperature, tested soaked unsoaked conditions. Specified curing periods 7, 14, 28 days applied all types specimens. Some engineering tests...
The distribution of critical marine habitats in Quy Nhon Bay, Binh Dinh Province, was assessed with the combination resolution Google Earth images and local knowledge through consultations ground truthing using small boats to check sites supporting coral reefs seagrass beds involvement. Detailed surveys on species diversity conditions were conducted at 24 four three (Nhon Ly, Hai, Ghenh Rang, Chau) 2016–2017. More than 152 ha reefs, 5 beds, 720 belonging 7 key groups (290 fishes;...
In this study, the deflection and stress field of perfect imperfect (with without porosities) functionally graded (FG) cylindrical panels are determined following first-order shear deformation theory (FSDT). The panel rested on two-parameter elastic foundation (Pasternak foundation) under pressure loads worked in a hygro-thermal environment. Navier’s solution has been used for simply supported to analyze effects porosity, geometrical parameters, as well temperature humidity field. validated...
This study successfully developed Co2SnO4@rGO nanocomposites at various composite ratios of Co2SnO4 and rGO using the sol-gel method. These were then used as heterogeneous catalysts to activate PMS in catalytic oxidation Co2SnO4@rGO/PMS well hybrid ozonation system O3/Co2SnO4@rGO/PMS degrade cefalexin (CFX). The physical-chemical characteristics fabricated evaluated through nitrogen adsorption-deadsorption, SEM images, EDS mapping, XRD. activity nanocomposite was investigated a degradation...
The lack of highly qualified labour force in the Vietnamese water and environmental sector as well problems mutual admission doctoral students between German Universities have motivated Institute Environmental Engineering Management (IEEM) at University Witten/Herdecke to initiate Water Doctoral Network (WDN). This network shall not be limited tuition conferral doctorates sciences, engineering economics, but serve nursery for new, innovative research potentials projects within international...

Natural calamities cause destruction of highways and artificial structures that they accommodate, thus, inflicting a substantial damage onto the national economy. The authors describe various natural phenomena geological processes typical for North Vietnam. reasons characteristics each type disasters are also provided in article. have generated set actions aimed at prevention or mitigation damages, enlisted make their conclusions respect future areas research monitoring interaction between...
Statement of the problem. Under conditions intensive development world road transport infrastructure, there is currently a shortage high-quality construction materials. One key solutions to address this problem use stabilized soil with inorganic binder make pavement construction. Results. The paper presents an overview study results in evaluating ability binders, and other adhesives combinations for also shows different levels indicators cement-stabilized combined Evocrete ST additive....
This study successfully developed a nanocomposite catalyst (Co2SnO4@rGO) at optimal composite ratio of 2:1 between Co2SnO4 and GO for effectively activation peroxymonosulfate (PMS) to degrade cefalexin (CFX) from aqueous solution by hybrid ozonation system (O3/Co2SnO4@rGO/PMS). The CFX removal efficiency was compared in three oxidation systems, including O3, Co2SnO4@rGO/PMS O3/Co2SnO4@rGO/PMS under various operational conditions initial concentration, PMS dosage, Co2SnO4@rGO dosage pH over...
Based on species composition and density data of fish egg larvae in South Central coastal sea areas Vietnam Sea waters were collected at Cù Lao Cham - Thu Bon river, Ly Son Tra Bong river Sa Ky Nha Trang Phu lagoon. Thirty-one eggs families identified (about 18% total 100% wholte larvae). Cu has the richest as 18 families, following to that is lower 15 10 respectively. The highest frequency was found such Mullidae, Engraulidae Synodontidae with 2 3 (groups). above account for about 60%...
