Means of livelihood is his utmost concern. The theory of cultural ecology which is still thriving can be used to analyze the cultural and social development and change in a Brazilian community.

In this study, poly (N-isopropylacrylamide) / chitosan (PNIPAAm / CS) composite membranes were fabricated, in which PNIPAAm was directly synthesized using NIPAAm monomers by means of free radical polymerization. Fourier transform infrared (FT-IR) spectroscopy was employed to characterize the membranes and the interactions. The lower critical solution temperature (LCST) of the swollen membrane was determined by differential scanning calorimetry (DSC). The morphologies of the obtained membranes were observed using scanning electron microscopy (SEM). The results showed that the composite membrane had good thermo-responsive performance. The construction of membrane became more regular with the increasing of CS. The hydrogen bondings have been formed between the two compositions of CS and PNIPAAm. Obvious phase conversion and shape change of the composite membrane have occurred below and above the LCST, which enhanced the mechanical properties of the composite menbrance. The results also showed that water absorption and mechanical properties of the menbrane were also affected by the PNIPAAm content.
