A Multinuclear NMR Approach to the Study of the Lyotropic System CTAB-D20
No full textCTAB-D2O liquid crystalline phase (CTAB = cetyltrimethylammonium bromide), type I according to magnetic anisotropy, has been investigated by means of 2H, 14N and 17O NMR at variable temperature. The residual quadrupolar splittings of ali these nuclei evidenced the alignment of the phase in the magnetic field. The interpretation of the data of D2O quadrupolar nuclei, commonly used in the Study of lyotropic liquid crystalline phases, is complicated because of water reorientation, exchange processes and variations of the hydration degree. The 14N quadrupolar splittings are much more reliable indicators of the orientation of surfactant aggregates since their interpretation in terms of the order parameter is straightforward in this case because the nitrogen nucleus is subject to an electric field gradient of axial symmetry and resides just in the head of the amphiphile

No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Jurídicas, Programa de Pós-Graduação em Direito, Florianópolis, 2014O trabalho parte do problema de tentar pensar uma forma de resistência pelo Direito. A hipótese sustentada encontra amparo na noção de "desativar" o Direito, contida na obra de Giorgio Agamben. Neste sentido, o trabalho busca recompor os paradigmas jurídico-político e governamental dentro da obra do autor em questão, principalmente a partir dos livros "O poder soberano e a vida nua", "Estado de Exceção" e "O Reino e a Glória". Ao fim, a proposta de "desativar" o Direito e o conceito de inoperosidade defrontam-se com a máquina governamental agambeniana. Na conclusão, a filosofia do Direito é apresentada como alternativa para se pensar uma nova relação entre Direito e vida.Abstract: The work begins from the problem of trying to think of a way of resistance by Law. The hypothesis is supported by the notion of "deactivate" the law, contained in the work of Giorgio Agamben. In this sense, this dissertation seeks to reconstruct the legal-political and governmental paradigms within the work of the author in question, mostly from the books "The sovereign power and bare life", "State of Exception" and "The Kingdom and the Glory". At the end, the proposal to "deactivate" the Law and the concept of unindustriousness are confronted with Agamben's government machinery. In conclusion, the philosophy of law is presented as an alternative to think about a new relationship between law and life
