Da crise do estado à democracia como alvo: Observações sobre o neoliberalismo a partir de Friedrich Hayek e Milton Friedman

The neoliberalism proclaims the crisis of the State in front of globalization , but, approaching two books taken as basic on this theoretical chain - The road to serfdom, of Friedrich Hayek, and Capitalism and Freedom, of Milton Friedman - to analyze this supposed dualism, the conclusion into which we arrive is another one. Remembering liberal tradition and quickly, later, analyzing critically the workmanships, can be perceived that others are the conflicts really gifts in the current capitalist reality - market versus State et capitalism versus democracy - and, from the understanding on the reading made and the theoretical trajectory of its authors, we may see as the neoliberalism locates itself in relation to these conflicts, which polar regions of these antagonisms privileges, what represents the State for itself, and what it intends as much more global philosophy than economic/politics thinking only

Desenvolvimento ninfal de Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae) sobre berinjela em diferentes temperaturas

Este trabalho teve como objetivo avaliar o efeito de diferentes temperaturas no desenvolvimento ninfal de Myzus persicae sobre folhas de berinjela (Solanum melongena). O experimento foi desenvolvido em câmaras climatizadas, sob condições controladas de temperatura de 15, 20, 25 e 30 ± 1 ºC, umidade relativa do ar de 70% ± 10% e fotofase de 12 horas. A biologia de M. persicae foi acompanhada sobre discos foliares de berinjela (3 cm de diâmetro) mantidos em placas de Petri contendo solução ágar-água a 1% geleificada. Foram estimadas as curvas mais ajustadas à duração dos estádios ninfais de M. persicae, suas equações de regressão e os respectivos coeficientes de determinação (R²). O número de estádios ninfais foi afetado pela temperatura; a 15 e 20 ºC, respectivamente, em 30,4% e 4,2% das ninfas observou-se um estádio adicional. Afídeos mantidos a 30 ºC apresentaram a menor viabilidade na fase ninfal (8%). A duração da fase ninfal foi de 9,4; 7,6; 5,9 e 7,0 dias, respectivamente, a 15, 20, 25 e 30 ºC. As temperaturas de 15 e 20 ºC foram as mais favoráveis para o desenvolvimento ninfal de M. persicae sobre discos de folha de berinjela.

A obra de triangulis omnimodis libri quinque de Johann Müller Regiomontanus (1436 1476): uma contribuição para o desenvolvimento da trigonometria

Trigonometry, branch of mathematics related to the study of triangles, developed from practical needs, especially relating to astronomy, Surveying and Navigation. Johann Müller, the Regiomontanus (1436-1476) mathematician and astronomer of the fifteenth century played an important role in the development of this science. His work titled De Triangulis Omnimodis Libri Quinque written around 1464, and published posthumously in 1533, presents the first systematic exposure of European plane and spherical trigonometry, a treatment independent of astronomy. In this study we present a description, translation and analysis of some aspects of this important work in the history of trigonometry. Therefore, the translation was performed using a version of the book Regiomontanus on Triangles of Barnabas Hughes, 1967. In it you will find the original work in Latin and an English translation. For this study, we use for most of our translation in Portuguese, the English version, but some doubt utterance, statement and figures were made by the original Latin. In this work, we can see that trigonometry is considered as a branch of mathematics which is subordinated to geometry, that is, toward the study of triangles. Regiomontanus provides a large number of theorems as the original trigonometric formula for the area of a triangle. Use algebra to solve geometric problems and mainly shows the first practical theorem for the law of cosines in spherical trigonometry. Thus, this study shows some of the development of the trigonometry in the fifteenth century, especially with regard to concepts such as sine and cosine (sine reverse), the work discussed above, is of paramount importance for the research in the history of mathematics more specifically in the area of historical analysis and critique of literary sources or studying the work of a particular mathematician

A difícil aceitação dos números negativos: um estudo da teoria dos números de Peter Barlow (1776-1862)

The present study seeks to present a historico-epistemological analysis of the development of the mathematical concept of negative number. In order to do so, we analyzed the different forms and conditions of the construction of mathematical knowledge in different mathematical communities and, thus, identified the characteristics in the establishment of this concept. By understanding the historically constructed barriers, especially, the ones having ontologicas significant, that made the concept of negative number incompatible with that of natural number, thereby hindering the development of the concept of negative, we were able to sketch the reasons for the rejection of negative numbers by the English author Peter Barlow (1776 -1862) in his An Elementary Investigation of the Theory of Numbers, published in 1811. We also show the continuity of his difficulties with the treatment of negative numbers in the middle of the nineteenth century

A figura do poeta em Friedrich von Hardenberg (Novalis) e Gaston Bachelard: algumas considerações

Através do Fogo - elemento marcante tanto em Novalis (século XVIII) quanto em Gaston Bachelard (século XX), pudemos ensaiar uma aproximação entre esses dois autores, distantes no tempo, mas próximos no tocante à valorização da imaginação (estética).

Proleptus acutus Dujardin, 1845 (Nematoda, Physalopteridae) parasite of rays Zapteryx brevirostris Müller & Henle, 1841 (Rhinobatiformes, Rhinobatidae) in Brazil

Relata-se a ocorrência de Proleptus acutus Dujardin, 1845 (Nematoda, Physalopteridae) parasitando Zapteryx brevirostris Müller & Henle, 1841 (Rhinobatiformes, Rhinobatidae) em Ubatuba, estado de São Paulo, Brasil. Vinte raias foram analisadas e P. acutus foi encontrado no estômago e intestinos de 14 (70%) animais. Este é o primeiro relato da ocorrência dessa espécie de nematóide em Z. brevirostris no Brasil.

The reproductive hiology and cycle of Rioraja agassizi (Muller and Henle, 1841) (Chondrichthyes : Rajidae) in southeastern Brazil, SW Atlantic Ocean

Specimens of Rioraja agassizi were collected Lit Guaruja pier, São Paulo State, Brazil, from March 2005 to March 2006. A total of: 275 males were captured. Based on the analysis of the clasper length, gonad weight, clasper gland length, alar thorns and lobule diameter, the size-at-maturity was estimated to be 32 cm. There were 1049 females in the record. Size-at-maturity was calculated in 40 cm. Sexual resting females were observed. Gonadosomatic and hepatosomatic indexes varied significantly in both sexes throughout the year. However, ovulation, egg-laying and presence of sperm in the seminal vesicle were observed all year round. For this reason, an annual cycle with at least one peak in the sexual activity is proposed for this species.

Hermenêutica e anti-hermenêutica: Friedrich Schlegel e Schleiermacher

A fortuna crítica de Friedrich Schlegel é rica em alusões a sua relação com Schleiermacher. Ambos conviveram em Berlim por volta de 1800, época em que Schlegel editava a Athenäum e em que Schleiermacher ainda não escrevera seus principais textos sobre hermenêutica. É possível conceber Friedrich Schlegel como um predecessor de Schleiermacher? Na tentativa de responder a essa pergunta, vamos nos deter sobre três textos, todos eles publicados na Athenäum: o ensaio sobre Lessing (Über Lessing, 1797), o ensaio sobre o Wilhem Meister de Goethe (Über Goethes Wilhelm Meisters Lehrjahre, 1798) e o ensaio da ininteligibilidade (Über die Unverständlichkeit, 1800).
