Premilinary Study in the Cause of Color in Zircon from Krông Năng Mining Area in Đắk Lắk Province
VNU Journal of Science: Earth and Environmental Sciences - - 2015
Zircon occurs in many colors including various shades of pink, red, purple, yellow, orange, brown as well as less common shades of green, and blue. Generally, the colors of zircon are caused by the trace element composition (transition metals, lanthanides, actinides and REEs) and radiation damage (radiation induced color centers) [1]. The color centers of zircon are complex and the details surroun......

Evaluation of the Ability to Treat Saline and Acid Sulfate Soils of Biochar from Rice Husks in Greenhouse Conditions
VNU Journal of Science: Earth and Environmental Sciences - Tập 38 Số 3 - Trang - 2022
The purposes of this study were to i) Examine the dynamics of physicochemical parameters of saline acid sulfate soil as influenced by biochar made from rice husk; and ii) Evaluate the influence of biochar on the soil quality index. A greenhouse experiment was carried out by mixing biochar with the tested soil at ratios of 0; 0.7; 1.5; 3, and 6% (w/w) and incubating for 100 days. Experimental soil ......

Effects of Monsoon Activity on Monthly Phytoplankton Blooms in the Gulf of Thai Land in El Nino Year 2002
VNU Journal of Science: Earth and Environmental Sciences - Tập 34 Số 2 - Trang - 2018
The Gulf of Thailand is a semi-closed Gulf on the west and southwest side of the Indochina Penisula and experiences reversal monsoon. The object of the present study is to investigate monthly and spatial distributions of the phytoplankton in the Gulf of Thailand during whole El Nino year 2002 by using remote-sensing measurements of chlorophyll-a (Chl-a) and surface wind vectors. Results show......

Study on Sediment Regime Changes in Downstream of the Ba River, Vietnam under the Impact of Reservoirs System
VNU Journal of Science: Earth and Environmental Sciences - Tập 33 Số 4 - Trang - 2018
Reservoirs system in upstream of Ba River has been affecting to the hydrology and sediment regime at the downstream. Sediment imbalance causes consequences such as erosion at river bank, lack of sediment supply to downstream areas and deposition/erosion in estuaries. This study focused on a quantitative assessment of the impact of Ba Ha reservoir and Song Hinh reservoir on sediment regime at the C......
