4. CONCLUSIONS A wideband X-band LNA integrated circuit have been designed using 0.15 µm GaAs pHEMT technology. In the frequency band from 6 to 11 GHz, the LNA achieves excellent performance with more than 25 dB gain and 1.3 - 2 dB noise figure. The output 1 dB compression power is 16 dBm and third-order intercept point is greater than 30 dBm. ...

4. CONCLUSION Influence of various dispersing auxiliaries on the nanosilica dispersion into passive Cr(III) solution were investigated. AE7 shown the best dispersing aid ability in the comparion with dispersing auxiliaries stuty. However, average particle size of nanosilica in Cr(III)-nanosilicaAE7 was approximately 60 nm, which was quintuple in...

4. 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 ...

Figure 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...

4. 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...

5. 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...

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...
