Abstract
Impacts of Vetiver Grass and DT2008 Soybean Cover Crop Practices on Soil Quality in Citrus Orchards in Cao Phong, Hoa Binh
Tập 40 Số 4 - Trang - 2024
Tran Thi Tuyet Thu, Le Ngoc Hieu, Le Nhat Ha, Ngo Hong Anh Thu, Pham Minh Ha
This study investigated the efficiency of biomass management, residue quantity, and quality from Vetiver grass and DT2008 soybean cover crops in improving soil quality, including carbon and nitrogen content and soil physiochemical properties. Mesocosm experiments in pots were conducted with six treatments, each was replicated three times: CT0 (control), CT1 (2% Vetiver grass mulch), CT2 (2% DT2008...... hiện toàn bộ
Assimilation of Sea Surface Temperature data for Central Vietnam’s Water Using Regional Ocean Modeling System (ROMS)
- 2021
Nguyen Kim Cuong
This paper presents the preliminary results of SST data assimilation for the Central Vietnam’s water using Regional Ocean Modeling System (ROMS). ROMS was used to assimilate with high-resolution SST from satellite with 4D-PSAS assimilation technique. Multi-scale Ultra-high Resolution (Mur) SST dataset which combines satellite and microwave data was used. ROMS has been set up based on the HYCOM pro...... hiện toàn bộ
Presence of Microplastic in Bottom Sediments of the Bach Hac River in Phu Tho Province, Vietnam
Tập 40 Số 4 - Trang - 2024
Duong Tuan Manh, Le Xuan Thanh Thao, Huynh Duc Long, Thai Thi Linh, Do Van Manh
Microplastic pollution has been one of the alarming environmental problems globally due to its widespread distribution and potential health risks. Rivers are considered one of the main pathways for microplastics receiving and transporting from land to the oceans. Furthermore, sedimentary environments are considered the main reservoirs of microplastics in the aquatic environments. This study was co...... hiện toàn bộ
Premilinary Study in the Cause of Color in Zircon from Krông Năng Mining Area in Đắk Lắk Province
- 2015
Bùi Thị Sinh Vương, Lê Thị Thu Hương
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...... hiện toàn bộ
The trajectories of perennial crops cover change in relationship with forest cover change in Bảo Lâm district, Lâm Đồng province
- 2018
Le Quang Toan, Pham Van Cu, Bui Quang Thanh
Abstract: The expansion of perennial crops area plays an important role for supporting the human livelihood in the Central Highlands, so have negative impacts on deforestation and sustainable development. Remote sensing and GIS were used to analyze the trajectories of perennial crops cover change in relationship with deforestation. The Logistic regression models were used to analyze proximate...... hiện toàn bộ
Turbidity Removal Efficiency of Tannin Based Flocculants Derived from Different Agricultural Waste
- Trang - 2024
Le Thi Hoang Oanh, Luu Minh Loan, Nguyen Van Hao, Dinh Thi Thuy
Tannin-based flocculants have been investigated, produced, and commercialized as a promising product in water supply and wastewater treatment. This study compared turbidity removal efficiency of tannin-based flocculants produced from different agricultural waste. Tannin was extracted using ultrasonic method (ethanol 50%, 2 h, 500 kHz) and modified according to Mannich reaction using HCHO and NH4Cl...... hiện toàn bộ
Isolation, Selection, and Cultivation of Antagonistic Lactic Acid Bacteria Against Postharvest Pathogenic Fungi in Grapes
Tập 39 Số 4 - Trang - 2023
Ngo Thi Tuong Chau, Nguyen Nhu Yen, Nguyen Thi Tu Le, Phan Thi Thao Ly, Le Van Thien
Incorporation of probiotics with edible coatings to preserve and improve the shelf life of fresh fruits has gained more popularity in the food industry. This study aimed to isolate, select lactic acid bacteria (LAB) that are antagonistic to postharvest pathogenic fungi in grapes (Vitis vinifera L.), and determine the optimal conditions for their biomass production. Fungi were isolated from decayin...... hiện toàn bộ

Preliminary Investigation of CO2 Sequestration by Chlorella sorokiniana TH01 in Single and Sequential Photobioreactors
Tập 36 Số 1 - Trang - 2020
Do Thi Cam Van, Tran Dang Thuan, Nguyen Quang Tung
Increasing accumulation of CO2 in the atmosphere mainly caused by fossil fuels combustion of human activities have resulted in adverse global warming. Therefore, searching for treatment methods for effective utilization of CO2 have received a great attention worldwide. Among various methods (e.g., adsorption, absorption, storage, membrane technologies, etc.) have been developed and applied, the se...... hiện toàn bộ
