Assessment of indoor and ambient air pollution at complex buildings in Hanoi
Abstract: The most typical air pollutants including PM10, CO, SO2, NOx are monitored at different sites indoor (basement, shopping malls) and outdoor (ambient air) of several complex buildings which are used for different purposes of resident, office, and shopping malls in Hanoi. The results show that the indoor air pollution concentrations tend...

Modeling the Red-Shanked Douc (Pygathrix nemaeus) distribution in Vietnam using Maxent
Abstract: The Red-shanked Douc (Pygathrix nemaeus) is the only douc species recorded in all three countries of Indochina. It is classified as Endangered by IUCN, and is believed to have experienced a major drop of more than 50% of its population over the last 40 years. The known distribution of main P. nemaeus populations in Vietnam ranges from ...

Implementation of tropical cyclone detection scheme to CCAM model for seasonal tropical cyclone prediction over the Vietnam east sea
Abstract: This study has selected a vortex tracking algorithm scheme for simulating the activity of tropical cyclone in the Vietnam East Sea by CCAM model. The results show that the CCAM model is able to simulate well the large scale in each month through a reasonable description of the movement rules of the tropical cyclone in the study area. T...

Investigate the relationship between Storm Formation and Tropical Cyclone Genesis Potential Index in the Vietnam East Sea
Abstract: In this paper, the relationship between Tropical Cyclone (TC) Genesis Potential Index (GPI) and the number of TC (NTC) associated with ENSO over the Vietnam East Sea (VES) was investigated. Observed TC data of the Regional Specialized Meteorological Center (RSMC) Tokyo Typhoon Center and ERA Interim reanalysis data for the period 1985-...

Sequence stratigraphy of South Central Coastal Quaternary sandy formation and stratigraphic significance
Abstract: The South Central Coastal Quaternary sandy formation has been studied by many authors according to different objectives, mainly for establishing quaternary geological maps ata different scale. There are 5 sedimentary cycles established based on the absolute age of the sand, that was analyzed by the method of thermoluminescent dating of...

Method of interpreting the high resolution seismic profiles: Principle and application in coastal shallow water area of Red River delta
Abstract: Establishing a process of interpreting the high-resolution seismic profile according to a sedimentary geological point of view is a very urgent task. The explanation process can be divided into the following steps: (1) Boundary demarcation of sequences based on unconformable surfaces showing signs of erosion of the river bed; (2) Analy...

Seasonal predictions of the number of tropical cyclones in the VietNam east sea using statistical models
Abstract: In this study, the equations for estimating the number of tropical cyclones (TCs) at a 6- month lead-time in the Vietnam East Sea (VES) have been developed and tested. Three multivariate linear regression models in which regression coefficients were determined by different methods, including 1) method of least squares (MLR), 2) minimum...

Application of DNDC model for mapping greenhouse gas emission from paddy rice cultivation in Nam Dinh province
Abstract: This study used the Denitrification-Decomposition (DNDC) model to calculate greenhouse gas emissions from a paddy rice cultivation in Nam Dinh province. The results show that the total CH4 emission from paddy rice field in Nam Dinh province ranges from 404 to 1146kg/ha/year. Total N2O emissions range from 0.8 to 4.2 kg/ha/year; The tot...

A study to assess the effectiveness of constructed wetland technology for polluted surface water treatment
Abstract: The study aims to assess the applying effectiveness of constructed wetland technology for polluted surface water treatment. The experimental models were operated with 2 hydraulic loadings of 500mL/min/m2 (T1) and 1500mL/min/m2 (T2). The reed grass (Phragmites australis) was selected for the studying process. The surface water resource ...

Variation of geosystems in Holocene Red river coastal zone
Abstract: The geosystem is a natural conditional system that is integrated by the lithofacies and ecosystems in space and in time in relation to sea level change, climate change, and tectonic movement. Another way, the geosystem is a natural unit including the causal relationship between ecosystem and lithofacies, in which the lithofacies is cau...
