4. CONCLUSION In the present investigation, a study has been carried out on the photocatalytic degradation of formic acid by Ni doped TiO2/SiO2 nano-composite. The experiment results showed that catalyst samples had uniform nano size, anatase crystalline structure and the band-gap energy of Ni-TiO2/SiO2 (2.88-3.00 eV) was lower than that of TiO...

4. CONCLUSION The results of the research on 62 households over 7 days determined the generation amount of household solid waste in Hue city as 286±171 g/person/day, higher than that of 7 years ago (258 ± 163 g/person/day). Among 17 different groups, the two groups making up the largest amount were food waste (56.35 %) and garden waste (10.89 ...

4. CONCLUSIONS Our study reveals that when the disaster in marine environment occurs, quantitative and qualitative investigations on benthic communities can effectively help to assess the quality of marine environment, with a reasonable budget, in comparison with chemical indicators. This finding can reduce the bias in assessing the quality of ...

4. CONCLUSIONS Water in the Park was - polluted by organic matter, not suitable for domestic use (QCVN 08-MT:2015/BTNMT column A2). Soil of the U Minh Thuong National Park had low pH (fromGreenhouse gases emission in U Minh Thuong National park, KienGiang province 3.88 to 5.12), high total phosphorus (> 0.1 %P2O5) and strong reduction (from -1...

4. CONCULUSION The installation of rainfall exclusion roofs in the native garden led to a significant decrease of soil moisture at the surface and the top layers of the soil profile (top 15 cm). The decrease in soil moisture resulted in a corresponding increase in CH4 uptake in the soil which is comparable to other temperate eucalypt forest stu...

4. CONCLUSIONS Based on the CSIRO-MK-3-6-0 model, by SimCLIM software, this research established precipitation scenarios in HCMC to 2100. By over the time and under the RCPs (RCP2.6 - RCP8.5), the average annual precipitation in HCMC would increase: 13.4 - 24 % by 2100 as compared to that in the period of 1986-2005 (1812 mm). The rainy season p...

4. CONCLUSIONS In the studied districts, rainwater was harvested from different types of roof including tile, concrete, fibro cement and metal roofing, of which tile roof is the most common one, counted for 65.6 %. The quality of roof harvested rainwater that was already separated 5-15 minute first rain then stored in the tank was rather good w...

4. CONCLUSION The present work indicated that the ethanol extract of Eupatorium fortunei Turcz at 500 µg/mL with inhibition efficiency of 95.5 % showed higher potential ability to inhibit the growth of M.aeruginosa than those of the water and methanol extracts with inhibitionefficiencyof 59.7 % and 66.5 %, respectively. In addition, pH level of...
