This work analyzes the consequences of the intersection between the two spheres polis and oikos. It does so by examining themes present in three plays: Medea, Agamemnon and Lysistrata. The focus of the analysis is the way in which the feminine characters react to conflicts of interests in their respective situations. To fully comprehend which values correspond to which mentioned institution, the work also necessarily investigates the socialization and functions of both genders in fifth-century Athenian society. The analysis of the feminine condition in the creation myth implies the importance of the misogynistic sense of that time, which culminated in the silencing, discrediting, and systemic repression of females. The role of women in society, instilled in all girls starting in early childhood, is to succeed in marriage and domestic permanence. This lies opposite the masculine role, which was focused outside of the family center and to environments relating to war and public life. Matrimony and family, traditional female values, were threatened when overlapping with male interests, such as unavoidable war or social ascension through a different matrimonial bond. Therefore, it is possible to affirm that the opposition evident in the definitions male vs. female indicates that, in certain contexts, the interests of each element cause the conflicts present in the chosen plays

This study investigated the main methods of separation of components of lignocellulosic biomass, with an emphasis on obtaining lignin and its application. The work was developed based on the concept of Biorefinery proposing full use of renewable raw materials and / or the use of lignocellulosic agricultural residues by biochemical or biotechnological conversion in obtaining high value added products with minimal environmental impact. From this premise, a literature review was performed in refereed journal articles and theses in order to gather enough material for critical analysis of usual and alternative methods in the literature. When researching methods that add value to lignin, it was found that with the technology found today, the cost required to have a degree of competitiveness is still too high, preventing much of the process. However, the isolated lignin can be used as raw material in the production of numerous types of biocomposites and polymers and other products such as phenols, benzene, dispersants, vanillin, emulsifying agents, antioxidants, pesticides, fertilizers, charcoal, concrete additives, among others. As an industrial production level is necessary, because the consumption of biomass will only grow over the years, it is necessary that new methods or technologies to be created in order to facilitate the extensive use of lignocellulosic biomass
