This study introduced a method to produce a thermosensitive nanocomposite hydrogel (nCur-PG) containing curcumin nanoparticles (nCur) which can overcome the poor dissolution of curcumin. Regarding to the method, a thermo-reversible pluronic F127-grafted gelatin (PG) play a role as surfactant to disperse and protect nanocurcumin from aggregation. The synthetic PG was identified by 1H-NMR. The obtained results via Transmission Electron Microscopy (TEM) and Dynamic Light Scattering (DLS) indicated that the size of nCur was various in the range from 1.5 ± 0.5 to 128 ± 9.

Adsorption by activated red mud (ARM) is investigated as a possible alternative to the conventional methods of Cr(VI) removal from aqueous synthetic solutions and industrial effluents. Adsorption characteristics suggest the heterogenous nature of the adsorbent surface sites with respect to the energy of adsorption. Various factors such as pH, contact time, Cr(VI) concentration, amount of adsorbent, and temperature are taken into account, and promising results are obtained.

Some Practical Considerations of Predictability and Learning Algorithms for Various Signals In this chapter, predictability, detecting nonlinearity and performance with respect to the prediction horizon are considered. Methods for detecting nonlinearity of signals are first discussed. Then, different algorithms are compared for the prediction of nonlinear and nonstationary signals, such as real NO2 air pollutant and heart rate variability signals, together with a synthetic chaotic signal.
