Microalgal culture with digestate from methane fermentation - Concentration of digestate on growth of three microalgal species - Nguyen Tran Thien Khanh4. CONCLUSION C. vulgaris, E. gracilis and D. tertiolecta showed the highest specific growth rate (µ) at 5 % digestate when the PPFD at the solution surface was 300 µ mol m−2 s−1 and at 30 °C. However, under different conditions, such as less or more than 5 % digestate, µ decreased. The decrease in µ when digestate concentration is less than 5 ...

Flavonoids and triterpenoids from callistemon citrinus and their inhibitory effect on no production in lps-Stimulated Raw264.7 Macrophages - Nguyen Manh CuongFigure 3 shows the inhibitory effects of the triterpenoids 8 - 12 against NO production. Activities were found to be in this order: 3β-hydroxy-urs-11-en-13(28)-olide (9) > betulinic acid (10) > 3β -acetylmorolic acid (8) > diospyrolide (11) > ursolic acid (12). Compound 9 showed the most remarkable inhibitory effect against NO production with in...

Application of data assimilation for parameter correction in super cavity modelling - Tran Thu Ha4. CONCLUSIONS In the model of slender body running very fast under water the coefficient k1 strongly effects to the simulation results (the right of Figure 5). By the results presented in Figures 3,4 it is easy to see that by the data assimilation method the corrected coefficient k1*can be nearly equal to the reference coefficient k1 . It foll...

Adaptive tracking control for twin rotor multiple-Input multiple-output based on iss stabilization - Nguyen Van Chi5. CONCLUSION This paper introduces the adaptive controller design based on the ISS stabilization to angle track problem for TRMS. In order to design the controller, the mathematical model of TRMS is rewritten in Euler-Lagrange forced model with uncertain parameters and input disturbance. By conssidering carefully the model, we found that the e...

Effect of Cyanobacteria nostoc Calcicola on Antioxidant system of soybean - Mai Van Chung4. CONCLUSION Strain Nostoc calcicola HN9 in death phase played as an unfavourable factor that caused a burst of ROS productions such as O2•- in stage V1 and H2O2 in stage V3, leading to oxidative stress in leaves of “Nam Dan” soybean. Treament by this cyanobacterial strain differently induced to non-enzymatic antioxidants: total phenolics earl...

About the robustness of adaptive feedback linearization controller for input perturbed uncertain fully-Actuated systems - Nguyen Van Chi3. CONCLUSIONS This paper refers to robustness of the fully actuated mechanical system which is considered by Euler – Lagrange forced model with input disturbances and contains constant uncertain parameters. By giving and proofing a theorem we conclude that the outputs of the system controlled by the adaptive feedback linearization controller w...

Improvement of CO2 purifying system by photocatalyst for application in microalgae culture technology - Doan Thi Oanh4. CONCLUSION V2O5/TiO2 photocatalytic material system was successfully fabricated with size 20 – 40 nm, BET specific surface area is of approximately 20 m2/g. This material strongly absorbs light in both UV area and 430 – 570 nm wave length area. V2O5/TiO2 photocatalytic material was a good catalyst for CO, NOx and SO2 conversion process. The...
