Liberdade e negação da vontade: análise do ser-livre como representação e na angústia

Common understanding about what freedom means has always been more or less related to the power to realize something intended, desired, a capability. Therefore, being free is commonly interpreted under the concept of free-will and the category of possibility to act. Although there are predecessors in History of Philosophy, Schopenhauer refuses the thesis of free will proposing otherwise the denial of willing (to live) as the ultimate possibility for human freedom, if not the only one left. The thesis that would make him famous was deeply misunderstood and so miscarried somewhat due to the way it was many times presented by the means of exotic examples wrapped in a mystical mood besides exaltations to Eastern traditions, which may satisfy anthropological curiosity instead of being capable to satisfy the reader in a philosophical way. It seems to result from Schopenhauer s thought a kind of pessimism against life. Otherwise, typical readings on the Schopenhauerian thesis are found full of inconsistencies once closely regarded, which blame does not belong to the author but to his interpreters. A new reading about the denial of willing as the ultimate possibility for human freedom demands a criticism on the inconsistencies and prejudgments deep grounded. For this, we firstly clarify the ways of understanding the willing nothing , which cannot be reduced to the mere refusal or conformism, being instead positively understood as a special manner of willing: the admission of oneself for the sake of one is. A few more than a century later The world as will and representation came to light, Heidegger proposes in his fundamental ontology that the proper being-free concerns to originary decision by which, in anguish of being suspended in nothingness, Dasein renders itself singular as the being who is in-a-world and to-death, concluding that the ultimate possibility of freedom is being-free-to-death. Developing the hypothesis that freedom, properly understood, concerns to nothingness as to indeterminate possibilities, we seek for a dialogue between Schopenhauer s thought and existential philosophy aiming to reconstitute and overcome Metaphysics tradition turning the question about freedom into a matter of Ontology. From the factual existence perspective, as we must show, every human activity (or inactivity) is ordinarily mediated by representations, in which me and world appear as distinct entities. So, each one among determininate individuals finds itself connected to the things in the world by interest, which proper concept must be sufficiently explored. Starting from this point, we may proceed to detailed analysis of usual representations of freedom aiming their destruction by Ontology and then reaching existential thesis according to Kierkegaard and Heidegger. Turning back to the analysis of Schopenhauer s work, we conclude existential understanding of freedom as will-to-be can also be found in Schopenhauer. In this way, denial of willing means ultimate freedom once the Will turns back to its own essence by suppressing the world as representation, which means the originary absolute indetermination of the extreme possibility to-be

Prospecção de genes de interesse biotecnológico : uma abordagem metagenômica

The total number of prokaryotic cells on Earth has been estimated at 4 to 6x1030 and only about 1% of microorganisms present in the environment can be cultivated by standard techniques of cultivation and plating. Therefore, it is a huge biological and genetic pool that can be exploited, for the identification and characterization of genes with biotechnological potential. Within this perspective, the metagenomics approach was applied in this work. Functional screening methods were performed aiming to identify new genes related to DNA repair and / or oxidative stress resistance, hydrocarbon degradation and hydrolytic activities (lipase, amylase and protease). Metagenomic libraries were built utilizing DNA extracted from soil samples collected in João Câmara RN. The libraries were analyzed functionally using specific substrate containing solid medium (hydrolytic activity), supplemented with H2O2 (DNA repair and / or resistance to oxidative stress) and liquid medium supplemented with light Arabian oil (activity, degradation of hydrocarbons). After confirmation of activity and exclusion of false-positive results, 49 clones were obtained, being 2 positive for amylase activity, 22 resistant to oxidative stress generated by H2O2 and 25 clones active for hydrocarbons degradation. Analysis of the sequences showed hypothetical proteins, dienelactona hydrolase, DNA polymerase, acetyltransferase, phosphotransferase, methyltransferase, endonucleases, among other proteins. The sequence data obtained matched with the functions tested, highlighting the success of metagenomics approaches combined with functional screening methods, leading to very promising results

Parâmetros urbanísticos para habitação de interesse social: uma análise crítica para as Rocas em Natal/RN

Through the comparative critical analysis of the demanded urbanistic parameters in the legislation and of the urbanistic index found in the Rocas neighbourhood, having as study object the already consolidated constructions of residential use, intended to demonstrate that the neighbourhood needes specific norms and that the limits established for recognition of Special Areas of Social Interest for the urbanistic legislation of the City of Natal would have to be reviewed and to be brought up to date, once they show occupations like the ones of the reffered neighbourhood. At a first moment, bibliographical revision and elaboration of the theoretical referencial had been made, , to analyze afterwards the urbanistic legislation for the neibourhood of Rocas, that determines relative parameters for the sizes of land lots, coefficients of exploitation, minimum taxes of occupation and retreat. Through a field research in the area, a study on the occupation description was done at first, characterization of the neibourhood through the study of the social-economic aspects, of the existing infrastructure in the place, environmental aspects, morphologic and tipolgic analysis of the neibourhood as a whole. From the grouping of the found characteristics, sub-zones had been delimited, where the real object of study was detached to be analyzed. From the Sub-zoning, a statistic sampling was carried through with the intention to examine which of the urbanistic index is found in the dwellings of that already materialized place. This sampling, of one hundred and eighteen residences, was carried through by measurement of the lots and existing constructions in these places. Through this survey, for each habitacional unit, area of the lot, constructed area, retreats and coefficient of exploitation had been calculated. The comparison between the legislation parameters and the index found in the place reveal an expressive index of urbanistic irregularity and the necessity of special regulation for the Rocas neibourhood due to its specific social-space characteristic

Fosfatos de cálcio de interesse biológico: importância como biomateriais, propriedades e métodos de obtenção de recobrimentos

For decades the Hydroxyapatite (HA) was only bioceramic of calcium phosphate system used for bone replacement and regeneration, due to its similarity to the mineral phase of bones and teeth. Because its slow degradation, other calcium phosphate classified as biodegradable started to awaken interest, such as: amorphous calcium phosphate (ACP), octacalcium phosphate (OCP) and tricalcium phosphate (TCP). This work presents the evolution of the use of other calcium phosphates due to their better solubility than the HA, comparing their main physical-chemical and biological properties. Are also presented the main methods used to obtain bioceramic coatings on metal and polymer surfaces.
