Contamination of microplastic in bivalve: first evaluation in Vietnam
Tập 41 Số 3 - 2019
Microplastics (MP) are omnipresent in ecosystems. Some studies focus on MP fates and their toxicology on biota for the last ten years in the world. In the present study, MP was identified in bivalve (Perna Viridis) collected in Vietnam for the first time using micro-Fourier transform infrared Microspectroscopy (µFTIR) technique. Organisms were digested by KOH 10% solution then separated using KI 5...... hiện toàn bộ

Sea-level rise and resilience in Vietnam and the Asia-Pacific: A synthesis
Tập 40 Số 2 - 2018
Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, ...... hiện toàn bộ

Determination of maximum tilt angle from analytic signal amplitude of magnetic data by the curvature-based method
Tập 40 Số 4 - 2018
Imaging buried geological boundaries is one of a major objective during the interpretation of magnetic field data in Geophysics. Therefore, edge detection and edge enhancement techniques assist a crucial role on this aim. Most of the existing edge detector methods require to obtain special points such as in general the maxima of the resulting image. One of the useful tools in estimating edges from...... hiện toàn bộ

Landslide susceptibility mapping using Forest by Penalizing Attributes (FPA) algorithm based machine learning approach
Tập 24 Số 3 - 2020
Landslide susceptibility mapping is a helpful tool for assessment and management of landslides of an area. In this study, we have applied first time Forest by Penalizing Attributes (FPA) algorithm-based Machine Learning (ML) approach for mapping of landslide susceptibility at Muong Lay district (Vietnam). For this aim, 217 historical landslides locations were identified and analyzed for the develo...... hiện toàn bộ

A Digital Shoreline Analysis System (DSAS) applied on mangrove shoreline changes along the Giao Thuy coastal area (Nam Dinh, Vietnam) during 2005-2014
Tập 39 Số 1 - Trang 87-96 - 2017
The paper deals with a combination of the Digital Shoreline Analysis System (DSAS) and remote sensing, studying historical mangrove shoreline changes and mangrove zoning in the GiaoThuy coastal area of the Nam Dinh province, Vietnam. The results show an over-all mangrove area increase of 2,487 hectares during the years 2005-2014. This dynamics results from both degradation and increase of the mang...... hiện toàn bộ

Assessment and Simulation of Impacts of Climate Change on Erosion and Water Flow by Using the Soil and Water Assessment Tool and GIS: Case Study in Upper Cau River basin in Vietnam
Tập 39 Số 4 - 2017
The Upper Cau river basin which plays an important role in socio-economic developments the North of Vietnam is sensitive to changes of climate influencing flows, erosion, and water resources. The main objective of this study is to assess and simulate impacts of climate change on erosion and water flow in the basin. Using a GIS database and Soil and Water Assessment Tool (SWAT) model, the water flo...... hiện toàn bộ

Analysis of gravity data for extracting structural features of the northern region of the Central Indian Ridge
Tập 45 Số 2 - Trang 147-163 - 2023
In this study, structural lineaments and fracture zones of the northern region of the Central Indian Ridge have been determined using gravity data from XGM2019e_2159 global gravity model. In this scope, firstly, the edge detection performances of the gradient amplitude of the tilt angle (THDR), theta map (TM), improved local phase (ILP), and improved logistic (IL) methods have been evaluated on sy...... hiện toàn bộ

ASSESSMENT OF GEOMORPHIC PROCESSES AND ACTIVE TECTONICS IN CON VOI MOUNTAIN RANGE AREA (NORTHERN VIETNAM) USING THE HYPSOMETRIC CURVE ANALYSIS METHOD
Tập 38 Số 2 - 2016
the Day Nui Con Voi (DNCV) area of Vietnam. For this purpose, a spatial database was collected and constructed, including DEM (Digital Elevation Model) and a geological map. The hypsometric curve (HC) analysis method and its statistical moments were adopted to use for the assessment. These methods have been widely used for the assessment of geomorphic processes and active tectonics in many areas i...... hiện toàn bộ
Prediction of soil unconfined compressive strength using Artificial Neural Network Model
Tập 24 Số 3 - 2020
The main objective of the present study is to apply Artificial Neural Network (ANN), which is one of the most popular machine learning models, to accurately predict the soil unconfined compressive strength (qu) for the use in designing of foundations of civil engineering structures. For the development of model, data of 118 soil samples were collected from Long Phu 1 power plant project, Soc Trang...... hiện toàn bộ

Estimation of Curie point depths in the Southern Vietnam continental shelf using magnetic data
Tập 41 Số 3 - 2019
This study attempts to estimate the thermal structure in the Southern Vietnam continental shelf by calculating the Curie point depth isotherm using magnetic data. The Curie point depth values, from 49 overlapping blocks 128 × 128 km in size, have been estimated by the exponential approach. This approach is based on the analytical solution of the exponential equations obtained from transforming the...... hiện toàn bộ
