Authors: Nguyen, Anh Tuan; Advisor: Nguyen, Si Linh; Nguyen, Van Quang (2021) - Air pollution is considered as a spot-on phenomenon amongst many problems
that urban areas are facing with. In Hanoi, the capital city of Vietnam, this is also
unavoidable. Furthermore, climate change and its side-effects are in-turn worsen the
atmospheric environment. Therefore, understanding the impacts and the relationship
between air pollution and climate change is critical to the air quality management in
Hanoi and its effort of striving for sustainable development down the road. To analyze
the condition of air pollution in Hanoi precisely, I have collected information at
national and local level (Hanoi) in dealing with the air pollution. Those are represented
by lots of ...

Authors: Nguyen, Minh Duc; Bui, Thi Lo; Do, Thi Ngoc Anh; Nguyen, Thi My; Nguyen, Van Quang; Trinh, Van Hanh (2016) - For the first time, species composition of termites in Bac Huong Hoa nature reserve has been recorded. We have identified 38 species belonging to 14 genera, 7 subfamilies and two families from this area. Among 14 genera recorded, the genus Odontotermes had the highest number of species and collected sample rate (9 species, accounted for 23.68% of total species number of the studied area collected samples), followed by Schedorhinotermes with six species (15.79%), Reticulitermes and Nasutitermes, with four species each (10.53%). The remaining genera had from one to three species (2.63-7.89%). In comparison with two nearby areas (Dakrong and Bach Ma), species composition of termites in B...

Authors: Nguyen, Van Quang; Nguyen, Quoc Huy; Nguyen, Thi My (2016) - The sampling was followed the method of rapid biodiversity assessment of termites by Jones and Eggleton (2000), and have conducted for the first time in Dak Lak. In the studied natural habitats both termite richness and relative abundance were decreased from primary forest to secondary forest then to savanna (20 species → 11 species → 9 species) and (56 encounters → 30 encounters → 27 encounters) respectively. In the tree plantations, both richness and abundance in pine plantation higher than those in rubber plantation (13 species and 8 species) and (62 encounters and 53 encounters) respectively. The litter feeders dominated in habitats with high human impacts (secondary forest and sa...

Authors: Le, Thi Ngoc Diep; Advisor: Nguyen, Van Quang (2021) - This research focuses on the effectiveness of foreign aid projects for CCR and sustainable development in the VMD. The temporal scope of this research is the period of eleven years, from 2010 to 2020. This study collected information on foreign aid projects, especially those for CCR and sustainable development in the study area. This study's spatial scope is the VMD. The study period is from December 2020 to May 2021.

Authors: Tran, Manh Trung; Nguyen, Tu; Nguyen, Van Quang; Do, Quang Trung; Pham, Thanh Huy (2021) - In this study, red-emitting AlPO4:Cr3+ phosphors have been successfully synthesized by
a facile sol-gel method. The Tanabe–Sugano diagram demonstrates that the surrounding sites of
Cr3+ ions have a high crystal field with Dq/B=2.47. The sharp 694-nm peak on the PL of AlPO4:Cr3+
phosphor could be attributed to the 2E→4A2 electron transition of Cr3+ ions. The AlPO4:0.3%Cr3+
phosphor presents the highest PL intensity, then a purple LED prototype is obtained by coating the
optimum powder on a UV LED chip. The color coordinates (0.2412, 0.1330) of the purple LED
prototype imply that AlPO4:Cr3+ phosphors are promosing to be used as deep red phosphor powder
for horticulture LED l...
