Building regression model to detemine and make a salinity map of fresh surface water in estuaries using multispectral image sentinel – 2A
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số S3 - Trang 67-77 - 2021
Estimating salinity intrusion for river sections near estuaries is currently a
very important problem because of its affects fresh surface water for
agriculture and daily life, especially with extreme weather events in climate
change conditions. Solving this problem by applying multi-spectral remote
sensing data is an effective approach to large scale long-term monitoring of
salinity change and ex...
Development and application of an integrated agriculture industrial system for enhancing livelihood of rural community in the “Nang” canal area in Tan Phuoc District, Tien Giang Province
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số SI1 - Trang SI84-SI94 - 2021
The objective of this research is to develop a “livelihood model” in the
combination with the local industrial activities for the community in the “Nang”
canal, Tien Giang province. The proposed model is developed on the basis of the
current state of existing livelihood conditions, taking advantages of available
natural conditions and additional resources (e.g., waste streams) and also the
applica...

Typical pathogens on plastic debris in downstream of Sai Gon and Dong Nai rivers: an initial observation
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 7 Số 1 - Trang 659-668 - 2023
Plastic pollution is recently receiving significant attention. In aquatic
ecosystem, plastic debris can provide a habitat for microbial communities,
including pathogens which might cause ad-verse impacts on aquatic animals and
human health. This study, for the first time, investigated densities of typical
pathogens of Coliforms and Vibrio spp. associated on plastic samples col-lected
in surface wa...

Distribution characteristics, material composition, and formation mechanism of basalt volcanic caves in Southeast Vietnam
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số SI2 - Trang SI106-SI119 - 2021
Late Cenozoic basaltic formations are widely distributed throughout southeast
Vietnam, occupying about 6617.15km2. During a geological survey in the Southeast
Vietnam, the population of volcanic caves has been discovered in the Gia Ty
forest area (Km123, National Highway 20), Tan Phu town, Tan Phu district, Bau
Ham commune, Trang Bom district, Bau Sen ward, Long Khanh city, Dong Nai
province. The ...

Application of GIS and remote sensing to build up a map of environmental geological suitability for residential buildings on Thi Vai river basin
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số 1 - Trang 1-11 - 2019
Geological environment zonation is to divide the areas into relatively
homogeneous units based on their natural factors such as hydrology, topography,
geology, disasters... to create geoenvironmental units which suit a specific
type of exploitation for the purpose of research or regional management. This
study presents a process of integrating GIS and remotely sensed data to develop
a map of envir...

Correlation between soil moisture content and reflection value of VV polarization, VH polarization of Sentinel-1 satellite: Study case of dragon fruit farm, Binh Thuan province
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số 2 - Trang 358-368 - 2021
Binh Thuan province is one of the driest provinces in the South Central region
in particular and Vietnam in general. The scarcity of water for agriculture in
this area in the dry season is very serious. Surface moisture is one of the
parameters included in the assessment of aridity. In this study, the authors
establish the correlation between VV reflectance value, VH reflectance value
extracted fr...

Estimate greenhouse gas emission, classify environmental protection and propose solutions for greening some industries in Long An province
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 1 Số M1 - Trang 15-25 - 2017
In order to improve the efficiency of environmental protection and make
favorable conditions for environmental management and supervision in industrial
zones in Long An province, the study of calculating greenhouse gas emission and
developing a set of criteria for classifying environmental protection for
industries being operated in this area is necessary. Greenhouse gas emission of
three industri...
Color removal efficiency of rice husk biochar modified with magnetized iron oxides and nano zero valent iron for decolorization of dyeing wastewater
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số 2 - Trang 105-114 - 2019
Rice husk biochar, a rich-carbon material, can be modified with other reactive
elements to improve its original properties for organic-contaminant removal
efficiency. In this study, rice husk was heated to 600 oC without air in a
closed-furnace for producing the rice husk biochar (BC600). BC600 was then
magnetized for making an intermediate magnetized rice husk biochar (BC600-mag).
Finally, nano z...
Modifying chitosan with n-butyl acrylate - antibacterial ability
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 2 Số 2 - Trang 12-18 - 2019
Polymer deriving from nature as Chitosan, which is one of the most abundant
natural polymers in the world has effectively antibacterial potentiality.
However, chitosan is relatively difficult for applications due to its
disadvantageous properties. In this article, modifying chitosan (CS) is the
grafting copolymerization using monomer n-butyl acrylate (BA) and tert-butyl
hydroperoxide (TBHP) as an ...
A review on the modification techniques to enhance the heavy metals sorption capacity of kaolin clay from south east Vietnam
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số SI2 - Trang SI176-SI199 - 2021
For decades, adsorption has been proved to be the best process of contaminated
water treatment because of its simplicity and lower costs as compared to other
traditional technologies. Clay minerals are promising natural adsorbents for
removing many pollutants such as heavy metals, organic and biological
pollutants. Kaolin, which composed of kaolinite and has layered structure. This
clay is dominan...
