Neste debate, historiadores latino-americanos comparam a pandemia de gripe de 1918-1919 com a que varre o continente em 2009, sobretudo as experiências de México, Argentina e Brasil. Analisam as estratégias adotadas nos dois momentos, com ênfase em isolamento, vigilância em portos e aeroportos, intervenções nas cidades. Comparam a atuação dos Estados nacionais e governos locais, a posição dos médicos e dos meios de comunicação e o comportamento das populações, especialmente no tocante ao medo e à morte. Analisam o desempenho das estruturas de assistência às populações e as medidas terapêuticas e profiláticas recomendadas por órgãos públicos de saúde, por interesses privados ligados à venda de medicamentos e pelas medicinas populares e caseiras. O debate trata, ainda, da influência que a experiência de 1918 teve sobre as avaliações da crise atual, bem como do legado que deixará para o futuro.

Simultanément à l' expulsion des jésuites du contrôles de l' éducaton formeI du royaume portugais, l'Ordre du 28 juin 1759 a décrété une reforme générale aux études, comme une des partie d'un ensemble de mesures modernisatoires qui ont été établisent dans le Royaume et dans ses domaines à la période comprise entre 1750 et 1777, pendant le royaume de D. José I et sous la direction de son principal ministre, Sebastião José Carvalho e MeIo, plus connu par le titre de noblesse de Marquis de Pombal. Notre thèse, locaIisée notament à la Capitanie de Bahia (Capitanie - division politique administrative du Brésil Colonie) entre les années de 1759 à 1827, a comme objet d'études les singularités du magistère bahianais et comme objectif, à partir de Ia référence théorique de l'histoire sociale des idées, comprendre comment les membres de cette nouvelle catégorie professionelle, crée pour préparés des cadres professionels mais bien qualifiés pour exercer leurs fonctions de burocratie de l'État, ont pris contact avec la pensée reforniste ilustré portugais du siècle XVIII, ont été véhiculé autant par des étrangérisés, comme par la législation pombalina (du Marquis de Pombal) et comme cet ensembIe théorique rapporté à la pensée, la vie et le travail d'enseignant de ces premiers représentants du magistère bahianais. L' analyse de la documentation (des lettres, et des ordres royals, des licences officielles pour exercer la fonction, et des serments des professeurs royal pour les plusieurs villages et capitanies; registres de correspondence reçues et envoyées par les chambres des villages; registres et correspondences expédiées par plusieurs autorités; provisions; tous les types de licences et autorisations; désignation; testament et inventaires) montre que les professeurs royals, malgré la quantité pas très nombreuses de membres, ont été extremement actifs sur les décisions les plus importantes de la période de celle qui est connue comme la crise du système colonial, qui, en Bahia, a eu ses particularités dans un mouvement d' émancipation politique seulement au mois de juillet 1823. Finallement, on a le but, dans le contenu de cette thèse de doctorat, d'offrir une connaissance sur l'histoire de l'éducation brésilienne et bahianaise qu' on retrouve encore entouré de doutes, préjugements et imterpretations équivoques qui insistent d'anaIyser le Brésil sous un stigmate du retard du royaume portugais, malgré sa production récente dans l'historiographie

The guava tree pest that has been requesting larger control frequency, in the area of Jaboticabal - São Paulo in the last years, is the psilideo Triozoida limbata. Thus, the objectives of this research were: a) Compare control tactics T. limbata based on monitoring and selectivity of insecticide to decrease the applications; b) To register and to correlate the natural enemies in habitants in guava tree ecosystem with the key pest and with meteorological factors; c) See if the control of T. limbata affects the population of fruit flies and d) To verify the efficiency of appropriate insecticides to IMP, in control of T. limbata. The experiment was conducted in 2004, in an orchard of Paluma cultivar in Vista Alegre do Alto, SP. The used strategies were (doses in g.a.i./100L water): control; imidacloprid + beta-cyfluthrin (2.5 + 0.3); acetamiprid (4.0); fenpropathrin (15.0) and regional conventional treatment. It was concluding that is possible to reduce the number of applications of less aggressive insecticides to the environment and the man, with the adoption of monitoring of T. limbata and implementing the action level. The natural enemies' populations densities (Scymnus spp., Cycloneda sanguinea, Azia luteipes, Crysoperla spp., Polybia spp., Brachygastra ssp.) present positive correlations with the populations of T. limbata. Population fluctuations of T. limbata and natural enemies are not altered by meteorological factors (precipitation and temperature) in irrigated orchard. The population of Anastrepha spp. is minimized when of the applications is for control T. limbata. The insecticides imidacloprid, imidacloprid + beta-cyfluthrin, acetamiprid and fenpropathrin are efficient in the control of T. limbata.

Este texto tem por objetivo ressaltar um aspecto que não tem sido tratado com a devida profundidade na literatura que estuda a formalização da Teoria Geral do Emprego, dos Juros e da Moeda de John Maynard Keynes (1936). Mais precisamente, o texto destaca a estratégia de formalização adotada por David G. Champernowne em seu artigo intitulado Unemployment, Basic and Monetary: the classical analysis and the keynesian, publicado em 1935-36 na Review of Economic Studies. Chamamos a atenção para o fato dele distinguir a teoria clássica da teoria de Keynes não apenas pelos pressupostos adotados por cada teoria, mas principalmente pela construção de subsistemas a partir de um sistema geral, com características recursivas (relações de causalidade) distintas. As explicações em prosa, a descrição algébrica das funções comportamentais e condições de equilíbrio e a ilustração por meio de diagramas, além da escolha de conjuntos específicos de variáveis para representar cada uma das teorias e suas diferentes versões são aspectos deste artigo de Champernowne que merecem uma análise mais minuciosa.

The digestive gland of Pomacea lineata, a prosobranch gastropod mollusc inhabiting both fresh water and land, does not contain cholinomimetic compounds as do the glands of species of Aplysia, marine opisthobranch gastropods, in which both acetylcholine and urocanylcholine are present. The only pharmacological action detected for the digestive gland of Pomacea was spasmogenic activity of a crude homogenate containing 0.1 g tissue equivalents on the snail's own esophagus bathed in 10 ml of a physiological solution prepared on the basis of the animal's hemolymph composition. The spamodic activity was not blocked by atropine, bromlysergic acid diethylamide or anthazoline.

The invertebrate's musculature still presents many elusive points, especially in molluscs that generally present smooth and cracked fibers with peculiar characteristics. It was found that the molluscs reactions to the ion variation in the bathing are not very clear, mainly in view of the isolated reduction or equivalent of the ions. Suspended in bath, the isolated esophagus of the P. lineata exhibited spontaneous activity. This rhythmic activity was sensitive to the ion variation of the perfusion liquid, evidenced by alterations in the spontaneous contractions. The equivalent reduction of the ion reduced the spontaneous activity, evidenced by the amplitude reduction of the response, besides maintaning an organ contraction, primarily in the reductions below 50%. When the isolated reductions of the Na, Ca or K ion were performed, occurred interference in the spontaneous contractions of the organs, principally in amplitude of the response and maintenance of the contracture in reductions of 50 and 25% of the ion.

1. 1. The respiratory responses of Pomacea lineata to short-term (or acute) exposure to temperature and oxygen tension variations were investigated in animals acclimated to 25°C. 2. 2. The respiratory rates increased with rising temperatures; this increase was sharper between 15 and 25°C than at any other temperature interval; a tendency to a plateau in the RT curve was recorded between 25 and 35°C. 3. 3. All animals survived well to 1 hr exposure to the extreme temperatures used (5 and 40°C). 4. 4. In two different experimental approaches, the animals showed ability to regulate the respiratory rate in declining oxygen tensions, at least down to 10% (70.8 mmHg) oxygen. 5. 5. After 1 hr exposure to hypoxic conditions, P. lineata exhibited the pattern of underpayment of the oxygen debt acquired. 6. 6. Six out of ten animals survived after 40 days in anoxia (100% nitrogen). © 1987.
