Variação espaço-temporal de cianobactérias na Bacia Hidrográfica do Rio Ipojuca (UP-03)

A Bacia Hidrografica do rio Ipojuca vem sofrendo enormes alteracoes nos ultimos anos em seu estuario, em decorrencia da instalacao do Complexo Industrial Portuario de Suape e, mais recentemente, da Termopernambuco. Nesta bacia tambem estao instaladas diversas agroindustrias que sao responsaveis por aproximadamente 72 % da carga orgânica de poluentes despejados na bacia. O objetivo desse trabalho foi avaliar os impactos provocados pela poluicao do rio Ipojuca. Com esse intuito, foi feito o levantamento da variacao espaco-temporal das cianobacterias presentes nos reservatorios da referida bacia. Em 2007, foram identificadas ocorrencias nos meses de junho a dezembro e no ano de 2008, todos os meses com excecao dos meses de maio e dezembro, confirmando que sao frequentes nos reservatorios dessa bacia devido ao processo de eutrofizacao dos efluentes agroindustriais e a falta de saneamento basico dos municipios drenados pela bacia. Nestes treze acudes foram identificados 25 generos de cianobacterias nas amostras coletadas no periodo amostral, pertencentes as classes Chroococcales, Oscillatoriales e Nostocales. Os fatores ambientais foram apontados como responsaveis pelo sucesso do desenvolvimento destes organismos. Concluindo, faz-se necessario o monitoramento constante dos parâmetros fisicos, quimicos e biologicos dos reservatorios da Bacia Hidrografica do rio Ipojuca como forma de evitar intoxicacoes das populacoes usuarias por cianotoxinas.

Structural Change in Agriculture in the Rice Granaries of Vietnam, Fifteen Years after DOI MOI

A decade after the introduction of the DOI MOI policy and agricultural reform, Vietnam was positioned as the world’s second largest rice exporter, whereas rice farming itself became a grim business. The government relaxed their egalitarian land allocation policy and encouraged diversification from rice monoculture. The land price had soared in 2000 and the 2003 land law stipulated measures to prevent land speculation. The objective of the research is to identify the effect of land speculation on the structural change in agriculture in the Mekong delta between 1997 and 2002. A follow-up census of an ex-hamlet was undertaken in Can Tho (current Hau Giang) province in 2002. Data from households were stratified by land size and compared with those studied from 1993 to 1997. Branchedout households had multiplied, probably due to the appreciation in land prices. Households were differentiated at around 1 ha subject to their competencies in rice production. Diversification from rice monoculture emerged as another factor differentiating farmers at around 2ha. A ceiling in yield due to land fragmentation and expectations of the agricultural land as an appreciating asset could have affected the farmers’ decision at around 3 ha whether to emigrate from or remain in the hamlet.

La sémiologie des odeurs au xixe siècle : du savoir médical à la norme sociale

Si de nombreux médecins appuient encore au xviiie siècle leurs diagnostics sur les odeurs émanant de leurs patients, celles-ci disparaissent progressivement, chassées par le grand mouvement hygiéniste à l’oeuvre au xixe siècle, à l’issue duquel, désormais, c’est l’absence d’odeurs qui garantit non seulement le statut social du sujet, mais aussi sa bonne moralité. En observant l’instauration de normes qui jalonnent ce chemin entre le discours médical et le discours social, telles que celles de la désodorisation et des usages du parfum, il s’agit de faire apparaître l’évolution tout au long du siècle des conceptions et des interprétations de l’identité olfactive.While many doctors in the 18th century still based their diagnoses on odours emanating from their patients, this reliance on odours gradually disappeared in the 19th century, thanks to the hygienist movement which lent credence to the absence of odours as assurance not only of social status but also the person’s moral character. By observing the development of standards that linked medical and social discourses, such as odour control and use of perfumes, this paper traces the evolution and interpretations of identity olfactory throughout the century

La peinture à vue de nez ou la juste distance du critique d’art, de Diderot à Zola

Since the emergence of exhibition practices in the eighteenth and nineteenth centuries, there has been a progressive normalization of the material conditions for observing paintings, such as their placement and the spectator’s distance to them. Just like painters and Salon visitors, art critics needed to move closer to their object of inquiry in order to gain better knowledge of it, but paradoxically, they could not claim objectivity without stepping back. The ideal distance that would allow viewers to simultaneously grasp the whole and the details was a contentious topic of discussion for nineteenth-century artists, critics, and scientists. Among the different ways in which this question was formulated in art criticism, one in particular reveals the presuppositions of the time about proximity: the constant reference to the smell of the painting. Associated with proximity, smell metaphorizes the pleasure or trouble spectators feel when they get close to paintings, to their pictorial materiality, or even to the figures depicted. Because smell always functions as a sign of the substance from which it emanates, art critics’ reference to it allowed them to consider the problem of proximity within the social and aesthetic issues of their time

Osteossíntese biológica em tíbia de cão com aplicação de fixador esquelético externo: relato de caso

Osteossíntese biológica é o tratamento dado, principalmente, às fraturas cominutivas diafisárias em quenão é possível a redução anatômica precisa dos fragmentos ósseos, preservando o alinhamento articularsem interferir no suprimento sanguíneo local. A fixação pode ser alcançada através de longa ponte na áreade fratura usando parafusos bloqueados, placas em ponte ou fixadores esqueléticos externos que levam àcicatrização do tecido ósseo fraturado. Demonstrou-se a utilização com sucesso desse princípio em cão comfratura cominutiva iatrogênica da tíbia causada pela colocação equivocada do fixador esquelético externo(FEE). A reintervenção cirúrgica com a aplicação do FEE baseando-se nos princípios da osteossíntese biológicapromoveu estabilidade aos fragmentos ósseos envolvidos e garantiu boa cicatrização do tecido.
