4. 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...

3. 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...

4. 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...

We have successfully prepared monodisperse and water-dispersible CoFe2O4 nanoparticles using one step synthetic method. The prepared nanoparticles are readily dispersible and relatively stable in aqueous solution without further surface monification steps. The particle sizecan be varied in the range of 7.2 - 11.3 nm with a standard deviation up ...

4. CONCLUSIONS The effect of hydrostatic pressure on sludge sonication disintegration was studied in recent years and reviewed in this work. As far as sufficient acoustic intensity was provided, an optimum pressure (> 1 bar) was found due to an increase in both cavitation threshold and cavitation intensity when increasing pressure. While the ef...

4. Conclusion 200-nm-thick PZT ferroelectric thin films have been successfully deposited on Nb:STO(111) single-crystal substrate via solution process, like an epitaxial growth. X-ray diffraction results showed that only PZT(111) peak appeared when annealing at 450, 500, 550 and 600oC. SEM images described that whole PZT thin films fabricated had n...

In this paper, oxidation possibility was assessed by determining total polyphenol, total flavonoid and total antioxidant capacity. Total polyphenol content was determined using the method of Folin - Ciocalteu, total flavonoid content was determined by using colour reaction with AlCl3, and total antioxidant capacity was evaluated by the phospho ...

4. Conclusions Cu2O and Au-Cu2O core-shell particles were successfully synthesized using chemical reduction method. The amount of reducing agent NH2OH.HCl has a significant influence on the morphology of the Cu2O particles. By varying the amount of NH2OH.HCl, several morphologies of the Cu2O particles such as cube, truncated cube and truncated ...
