Amostragem de poluentes particulados emitidos pela queima de biomassa em correntes confinadas

It is clear today the ever-accelerating search for new fuels that will eventually replace those that will survive in our society, which are fossil fuels. For this reason, a fuel used since the dawn of humanity and much studied since then, considered the generator of clean, renewable energy, can earn more and more space in the power generation sector, which is biomass. We performed two experiments with two different types of biomass, one from the Amazon rainforest and other pine and eucalyptus as waste from the sawmill UNESP Itapeva. In the first experiment, conducted at the Laboratory of Combustion and Propulsion INPE Cachoeira Paulista were conducted three tests in a chimney with a fan creating forced ventilation, where the biomass was burned and deposited on a support beneath the hood. In the second experiment was conducted to analyze the emission of particulate matter using biomass (waste) from the sawmill on the campus of UNESP experimental Itapeva the burning of it in a burner for heating water for a wood oven. In these experiments we used a particle called DATARAM4 sampler that is capable of sampling both outdoors and inside of pipelines, which is the focus of this work. With this equipment it was possible to measure the concentration of particulate matter in all the firings as above, and compare them to levels acceptable in the current law, always trying to analyze the so-called fine particles, which are those with diameters less than 2.5 μm. Using data obtained from the equipment was also possible to evaluate the diametral distribution of particulate matter in question, and verify which phases of the flares in the concentration and the diameters of the particles are the most critical. In this work we concluded that in all firings conducted concentrations of particulate matter were higher than that allowed by the law, and the diameters were found that are more harmful to human health

Do ciberespaço à iconomia: projeções metapóricas

Na sociedade contemporânea o ser humano se vê inserido – ou invadido – em ambientes cada vez mais configurados por complexos recursos tecnológicos. É o ciberespaço, onde as imagens inundam o cotidiano e se traduzem em valor, o corpo adquire novo status imaterial e as noções de lugar e tempo se transformam e quase se anulam. O cinema pensa e produz também uma desterritorialização da imagem em movimento desde os seus primeiros tempos de imagem-máquina. Este trabalho reflete sobre as transformações da ordem social que implicam a emergência de uma “iconomia” a partir dos espaços simbólicos, tomando três momentos críticos na história do cinema como índices de uma convergência entre material e imaterial que se consolida a partir da emergência do ciberespaço. O quase-método metapórico é mobilizado como ferramenta de reconstrução metodológica desses ícones da história do cinema relacionados à desconstrução do Homo faber. O “outro lado” do ciberespaço, abrindo continuamente novos espaços-tempos de criação de valor, identifica-se a uma iconomia em que as projeções narrativas tornam-se fontes paradigmáticas de valor e de “mais gozar”.

Constraining anomalous Higgs boson interactions

The recently announced Higgs boson discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmetry breaking now requires probing the Higgs boson interactions and searching for additional states connected to this sector. In this work, we analyze the constraints on Higgs boson couplings to the standard model gauge bosons using the available data from Tevatron and LHC. We work in a model-independent framework expressing the departure of the Higgs boson couplings to gauge bosons by dimension-six operators. This allows for independent modifications of its couplings to gluons, photons, and weak gauge bosons while still preserving the Standard Model (SM) gauge invariance. Our results indicate that best overall agreement with data is obtained if the cross section of Higgs boson production via gluon fusion is suppressed with respect to its SM value and the Higgs boson branching ratio into two photons is enhanced, while keeping the production and decays associated to couplings to weak gauge bosons close to their SM prediction.

Migración y ecología trófica de peces migradores verticales dominantes del Atlántico nordeste subtropical: implicaciones en el flujo activo de carbono

[EN]Diel vertical migrants (DVMs) are mainly zooplankton and micronekton that migrate upward from 400-700 m depth every night to feed in the productive epipelagic zone and come back at dawn to the mesopelagic zone, where they release the ingested carbon. DVMs should contribute to the biological pump in the ocean and, accordingly, to thevglobal CO2 balance. A large portion of the DVMs biomass are the lanternfishes (myctophidae), which might represent a pathway accounting for a substantial export of organic carbon to the deep ocean. Nevertheless, the magnitude of this transport is still poorly known. The combined study of migration and feeding ecology is a good approach to improve our knowledge of the DVMs role in this active carbon flux. Two dominant myctophids in the Subtropical Eastern North Atlantic Ocean (Hygophum hygomii (Lütken, 1892) and (Lobianchia dofleini (Zugmayer, 1911)) were studied from several surveys carried out around the Canary Islands during the last decade. Our results showed a marked diel vertical migration and a prevailing nocturnal feeding with predation mainly on copepods and euphausiids. The digestion state of prey suggested a slow stomach evacuation rate and that most of the ingested carbon in the epipelagic is efficiently transported to the mesopelagic zone.

Analisi d'immagine, patologia quantitativa e dimensione frattale in patologia veterinaria: Densita' e forme

Fino dagli albori della metodica scientifica, l’osservazione e la vista hanno giocato un ruolo fondamentale. La patologia è una scienza visiva, dove le forme, i colori, le interfacce e le architetture di organi, tessuti, cellule e componenti cellulari guidano l’occhio del patologo e ne indirizzano la scelta diagnostico-classificativa. L’osservazione del preparato istologico in microscopia ottica si attua mediante l’esame e la caratterizzazione di anomalie ad ingrandimenti progressivamente crescenti, a diverse scale spaziali, che partono dalla valutazione dell’assetto architettonico sovracellulare, per poi spostarsi ad investigare e descrivere le cellule e le peculiarità citomorfologiche delle stesse. A differenza di altri esami di laboratorio che sono pienamente quantificabili, l’analisi istologica è intrinsecamente soggettiva, e quindi incline ad un alto grado di variabilità nei risultati prodotti da differenti patologi. L’analisi d’immagine, l’estrazione da un’immagine digitale di contenuti utili, rappresenta una metodica oggettiva, valida e robusta ormai largamente impiegata a completamento del lavoro del patologo. Si sottolinea come l’analisi d’immagine possa essere vista come fase descrittiva quantitativa di preparati macroscopici e microscopici che poi viene seguita da una interpretazione. Nuovamente si sottolinea come questi descrittori siano oggettivi, ripetibili e riproducibili, e non soggetti a bassa concordanza inter operatore. La presente tesi si snoda attraverso un percorso concettuale orientato ad applicazioni di analisi d’immagine e patologia quantitativa che parte dalle applicazioni più elementari (densità, misure lineari), per arrivare a nozioni più avanzate, quali lo studio di complessità delle forme mediante l’analisi frattale e la quantificazione del pattern spaziale di strutture sovracellulari.

Les villages préhistoriques des bords des lacs circum-alpins entre le Ve et IVe millénaire av. J.-C.

Connus sous le nom populaire de palafittes, les habitats préhistoriques construits sur les rives des lacs subalpins du Néolithique à l’aube de l’âge du Fer (entre 5300 et 700 av. J.-C.) offrent des informations exceptionnelles sur l’évolution culturelle d’une importante région européenne, grâce à la préservation remarquable des matériaux organiques, en particulier du bois. À partir de la deuxième moitié du XXe siècle, le perfectionnement des techniques de fouille subaquatiques et de la dendrochronologie permettront la construction d’un schéma chronologique précis pour l’Europe nord-alpine. Les recherches contribueront à des observations d’ordre écologique à l’échelle locale et régionale et à l’identification des rythmes de développement des villages. Sous l’égide de l'UNESCO, les années 2010 verront la constitution d’un inventaire vaste et uniforme des sites préhistoriques des lacs circumalpins, classés Patrimoine culturel mondial en juin 2011.

Die Odyssee der Pygmäen. Eine prekäre Figur auf den neuzeitlichen Spieltischen anthropologischer Differenz

Due to the impacts of postcolonialism, social and cultural anthropology has been dealing intensively with the possibilities and limits of representing "other” human beings and their meaningful worlds. Scholars such as George Marcus, James Clifford or Clifford Geertz have discussed ways of improving anthropological methods of representation without, however, fully raising questions about the quality and validity of the objects represented and the very idea, that they could be “represented”. Thus, despite attempts to purify classical anthropological categories, substantialized presences (“Humans”, “Others”, “Pygmies” etc.), various forms of binary oppositions (us–them, culture–nature, human–animal) as well as certain epistemological modes/ logoi (representation, interpretation) have been rehearsed until today. The research aims to dissect and challenge the metaphysical outputs of the “anthropological machine” (Giorgio Agamben). I intended to solve these from their apparent familiarity as representable identities or differences in order to investigate their genealogy. In Derrida’s and Foucault’s understanding, genealogy becomes manifest mainly in the “blind spots” (Derrida) or “anomalies” (Foucault) between differences, at the borders of identities. As an analytical guideline, the research uses on one concrete metonym for the Derridean blind spot, one incorporation of a Foucauldian Other, namely pygmy narratives within early modern and 19th century imaginings. “Pygmies” have been part of both Western mythology and anthropological reflection since the antiquity and finally became “ethnographical facts” within an evolutionary anthropology in the 19th century during the European exploration of Africa. Throughout this veritable Odyssey, they were mostly precarious “category-jammers” (Timothy Beal), occupying the impossible middle grounds within (proto)anthropological classification. Thus, along with the early modern wild men, enfants sauvages or the apes of proto-primatology, the pygmies of the Homeric myth, as a catalyst for the negotiation of categories, played a decisive role in early modern and 19th century conceptions of the human. Through the precarious Pygmies, concrete socio-historical materializations of Identities (human, European), differences (human–animal etc.), as well as the accompanying logoi which vindicate these as pseudo-entities, appear evident. The research aims to read and write the history of early modern and 19th Century anthropology through one of its many classificatory constituting Others. It thus contributes to a discipline that for a long time has examined concrete systems of knowledge and the genealogy of classification in general. One might call it an “anthropologization” of anthropology.

La práctica dialéctica y el advenimiento de la filosofía platónica

En los albores mismos de su filosofía, Platón muestra especial interés por determinar en qué consiste la indagación filosófica o dialéctica. En este trabajo intentaremos reconstruir el proceso mediante el cual Platón lleva a cabo su propósito, centrándonos en el examen de los comienzos de este proceso, que ciertamente se extiende hasta los últimos escritos platónicos. A partir del análisis de la Apología, el Laques y el Cármides, sostendremos que para Platón lo que se espera del auténtico indagador-filósofo -al menos en lo que toca a estos tres diálogos socráticos- es que sea capaz de definir con claridad y corrección qué es cada cosa, conjuntamente con un otro, en el seno de una discusión que dé a la vez que reciba razones bien fundamentadas. De este modo, esperamos poner de manifiesto la notable identificación que opera Platón entre el propio advenimiento de su pensamiento y la instauración de lo que él presenta como práctica dialéctica

Las leyes sobre vagancia : Control policial y práctica judicial en el ocaso de la frontera (Tandil 1872-1881)

A fines de la década de 1870, el gobierno provincial, con el objeto de lograr mayor control social sobre la población rural, implementó una reestructuración policial en la campaña bonaerense. La misma tenía por objetivo afianzar la propiedad privada y contribuir al mercado de trabajo, asimismo perseguía un fuerte interés en satisfacer la necesidad del estado de hombres en plena etapa de expansión de la frontera. La presión reclutadora del estado se reflejará en un aumento de detenidos por vagancia, dado que las leyes de represión de la vagancia del Código Rural permitían su penalización al servicio de las armas. El Código Rural sancionado en 1865 estipulaba dos normas procesales a cumplir en los acusados: formación de un sumario y constitución de un jury para su juzgamiento. Disposiciones que raramente se pusieron en práctica por los jueces de paz desde que esta legislación entró en vigencia. Será a fines de la década de 1870 cuando el gobierno exigirá más firmemente no solo la persecución de la vagancia sino también la aplicación de estas normas procesales en los acusados. Aún así, el análisis de la práctica judicial revelará que continuará existiendo una constante manipulación normativa sobre la base de dos valores que se intentaban afianzar, el trabajo y la propiedad. En los perjudiciales que atentaran contra estos dos valores, será en quienes se manipulará la normativa sancionada y se canalizará la presión reclutadora.
