Full textAbstract:
The early Eocene experienced a series of short-lived global warming events, known as hyperthermals, associated with negative carbon isotope excursions (CIE). The Paleocene-Eocene Thermal Maximum (PETM or ETM-1) and Eocene Thermal Maximum 2 (ETM-2) are the two main events of this Epoch, both marked by massive sea-floor carbonate dissolution. Their timing, amplitude and impacts are rather well documented, but CIEs with lower amplitudes also associated with carbonate dissolution are still poorly studied (e.g. events E1 to H1), especially in the terrestrial realm where hiatus/disconformities and various sedimentary rates in a single succession may complicate the assignation to global isotopic events. Here we present a new high-resolution multi-proxy study on the terrestrial, lagoonal and shallow marine late Paleocene-early Eocene succession from two sites of the Cap d’Ailly area in the Dieppe-Hampshire Basin (Normandy, France). Carbon isotope data (δ13C) on bulk organic matter and higher-plant derived n-alkanes, and K-Ar ages on authigenic glauconite were determined to provide a stratigraphic framework. Palynofacies, distribution and hydrogen isotope values (δ2H) of higher-plant derived n-alkanes allowed us to unravel paleoenvironmental and paleoclimatic changes. In coastal sediments of the Cap d’Ailly area, δ13C values revealed two main negative CIEs, from base to top CIE1 and CIE2, and 3 less pronounced negative excursions older than the NP11 nannofossil biozone. While the CIE1 is clearly linked with the PETM initiation, the CIE2 could either correspond to 1) a second excursion within the PETM interval caused by strong local environmental changes or 2) a global carbon isotopic event that occurred between the PETM and ETM-2. Paleoenvironmental data indicated that both main CIEs were associated with dramatic changes such as eutrophication, algal and/or dinoflagellate blooms along with paleohydrological variations and an increase in seasonality. They revealed that the intervals immediately below these CIEs are also marked by environmental and climatic changes. Thus, this study shows either 1) a PETM marked by at least two distinct intervals of strong environmental and climatic changes or 2) at least one “minor” CIE: E1, E2, F or G, was associated with strong environmental and climatic changes similar to those that occurred during the PETM.

Resumo � A regi�o Amaz�nica possui uma grande diversidade de peixes, s�o mais de 6.000 esp�cies catalogadas, mas ainda s�o pouco estudadas. S�o pouqu�ssimas esp�cies de peixes sendo exploradas e comercializadas nessa regi�o, aproximadamente 40 esp�cies podem ser encontradas nos mercados de peixes. Objetivou-se com este trabalho fazer um levantamento das principais esp�cies de peixes comercializadas na Feira do Pescado na cidade de Santar�m - PA, identificando-o as principais esp�cies, o valor atribu�do (R$), o equipamento utilizado e o local de captura. Para fazer o levantamento dos principais peixes comercializados na Feira do Pescado, foi aplicado um question�rio estruturado � 10 comerciantes de um total de 30 comerciantes presentes na feira. Foram identificadas 19 esp�cies de peixes que foram comercializadas na Feira do Pescado, desde o m�s de setembro de 2017 � janeiro de 2018. As principais esp�cies encontradas foram: o tambaqui (Colossoma macropomum) que � tanto oriundo de rios/lagos e tamb�m criados em viveiros para comercializa��o; outras esp�cies se destacaram pela presen�a e demanda de procura s�o elas o tucunar� (Cichia ocellaris), o pirarucu (Arapaima gigas), o acaratinga (Geophagus proximus), e a pescada (Plagioscion squamosissimus). Sendo que o �pice da comercializa��o dessas esp�cies mostrou-se maior nos meses de Dezembro e Janeiro. J� os pre�os das esp�cies foram maiores para os peixes de grande e m�dio porte j� eviscerados e escamados, o que foram atribu�dos valores agregados aos produtos. Como sabemos, nas feiras, o pre�o do produto � influenciado pelos per�odos de proibi��o da pesca, em detrimento de fatores como tamanho e caracter�stica morfol�gica das esp�cies, justificado pela lei da oferta e procura. Apesar da Feira do Pescado de Santar�m � PA apresentar uma variedade de esp�cies de peixes comercializados nota-se uma percept�vel diminui��o de esp�cies encontradas quando comparado com trabalhos anteriores.

Full textAbstract:
Ground source heat pumps (GSHPs) are now widely used in community integrated energy systems (CIES) because of their high efficiency in energy conversion. However, the coefficient of performance (COP) of GSHPs is unstable if the soil temperature changes with seasonal imbalanced cooling and heating loads, thus downgrading the overall performance of CIES. In this paper, an annual optimization model for CIES that considers the seasonal balance of GSHPs is established. Then, a day-ahead operation strategy based on the pre-allocated load of the GSHP in the yearly balance is proposed while considering the uncertainties in daily conditions. The proposed strategy is validated on a practical CIES in China and assessed on a year-round time scale. The results show that the operation of CIES can be stable, economical and sustainable while ensuring the seasonal balance of the GSHP.

This work reports the influence of the poly (ethylene terephthalate) textile and films surface modification by plasmas of O2 and mixtures (N2 + O2), on their physical and chemical properties. The plasma surface polymeric modification has been used for many researchs, because it does not affect the environment with toxic agents, the alterations remains only at nanometric layers and this technique shows expressive results. Then, due to its good acceptance, the treatment was carried out in a vacuum chamber. Some parameters remained constant during all treatment, such as: Voltage 470 V; Pressure 1,250 Mbar; Current: 0, 10 A and gas flow: 10 cm3/min, using oxygen plasma alternating the treatment time 10 to 60 min with an increase of 10 min to each subsequent treatment. Also, the samples were treated with a gas mixture (nitrogen + oxygen) which was varied only the gas composition from 0 to 100% leaving the treatment time remaining constant to all treatment (10 min). The plasma treatment was characterized in-situ with Optics Emission Spectroscopy (OES), and the samples was characterized by contact angle, surface tension, Through Capillary tests, Raman spectroscopy, Infrared attenuated total reflection (IR-ATR) and atomic force microscopy, scanning electronic Microscopy (SEM) and X-ray Photoelectron Spectroscopy (XPS). The results showed that oxygen treated fabrics presented high wettability, due to the hydrophilic groups incorporation onto the surface formed through spputering of carbon atoms. For the nitrogen atmosphere, there is the a film deposition of amine groups. Treatment with small oxygen concentration in the mixture with nitrogen has a higher spputered species of the samples
Neste trabalho, investigou-se a influ?ncia do tratamento superficial a plasma utilizando como gases de trabalho o oxig?nio e uma mistura de nitrog?nio + oxig?nio, sobre as propriedades f?sicas e qu?micas de tecidose filmes de Poli?ster. A modifica??o superficial de superf?cies polim?ricas por plasma tem sido bastante utilizada, pois a mesma n?o apresenta agentes nocivos ao ambiente, ?s altera??es promovidas no material s?o de escala nanom?tricas, e comprovadamente ? a t?cnica que tem apresentado resultados mais expressivos. Ent?o, tendo em vista a boa aceitabilidade do uso do plasma em materiais polim?ricos, O tratamento foi realizado em uma c?mara contendo os gases de trabalho sob baixa press?o (~ 1 mbar) mantendo-se constante durante todo ensaio alguns par?metros do plasma, tais como, voltagem: 470 V; press?o: 1,250 mbar; corrente: 0,10 A e fluxo de g?s: 10 cm3/min, usando plasma com atmosfera gasosa de oxig?nio variando-se o tempo de tratamento de 10 - 60 min com incremento de 10 min a cada tratamento subseq?ente, e tamb?m usou-se a atmosfera gasosa composta por uma mistura de nitrog?nio e oxig?nio, variando a concentra??o gasosa dos mesmos (de 0 100%), para um tempo de tratamento de 10 min. O tratamento por plasma foi caracterizado in-situ com o auxilio da Espectroscopia de Emiss?o ?tica,e as amostras foram caracterizadas por medidas de ?ngulo de contato, tens?o superficial, arraste capilar, espectroscopia Raman, Espectroscopia de infravermelho de reflex?o total atenuada (IR-ATR), e microscopia de for?a at?mica (AFM), Microscopia Eletr?nica de Varredura (MEV) e por espectroscopia de fotoel?trons excitados por raios-X (XPS). Os resultados mostraram que tecidos tratados com atmosfera de oxig?nio apresentaram elevada molhabilidade, devido a incorpora??o de grupos hidrof?licos na superf?cie formados com o arrancamento de ?tomos de carbono. Para a atmosfera de nitrog?nio, tem-se a deposi??o de um filme com base em em grupos aminas. Tratamentos com a concentra??o pequena de Oxig?nio numa mistura com Nitrog?nio tem-se maior arrancamento de esp?cies das amostras

Full textAbstract:
El descubrimiento de nuevos y novedosos materiales, procesos y fenómenos a escala
manométrica, así como los nuevos métodos experimentales y teóricos proveen
oportunidades para el desarrollo de sistemas innovadores a esa escala. La naturaleza
muestra como construye objetos macroscópicos desde unidades básicas con formas
definidas, propiedades, orden y control estructural en materiales. Este concepto es
utilizado para la construcción de macro-sistemas, orgánicos e inorgánicos, desde una
estrategia “bottom-up”.
El trabajo de la tesis se ha centrado en el estudio experimental de sistemas modelo muy
diferenciados (uno orgánico y otro inorgánico): i) películas autoorganizadas (selfassembled
monolayers, SAMs) de organosulfuros sobre Au(111), en concreto (C20H16O2S,
mercaptomethyl therphenyl carboxylic acid, MMTA) y ii) substratos óxidos tipo
perovskita, en concreto SrTiO3 (STO). La técnica que se ha utilizado es la microscopia de
fuerzas de barrido (Scanning Force Microscopy, SFM) tambien llamado microscopio de
fuerzas atómicas (Atomic Force Microscopy, AFM) con el fin de obtener información
sobre las propiedades estructurales, mecánicas y electrónicas (transporte y
electrostáticas) de estas superficies y establecer correlaciones entre las propiedades y la
funcionalidad. El presente trabajo consta de 7 capítulos, los primeros 5 capítulos
describen la completa caracterizacion del sistema pi-conjugado MMTA. Una
introducción a la técnica SFM en sus diversos modos de uso, preparacion de substratos,
soluciones y procesos termicos involucrados para observar posibles cambios
morfólogicos son abordados en el capítulo 2.
El capítulos 3 de la tesis describe el trabajo realizado desde la preparación de las capas
hasta su caracterización. Para poder estudiar la influencia de los solventes en la
estructura y propiedades de las superficies, se ha utilizano toda una serie de protocolos
en los que se han variado todos los parámetros involucrados en la preparación:
solventes (etanol (EtOH, 99.8%), ácido acético (AA, 99%), tetrahydrofuran (THF) y ácido
trifluroacético (TFA, 99%)), concentraciones (de 1 μM hasta 1 mM) y tratamientos
térmicos (25°C y 120°C y post-annealing). También se incluye en la tesis la
funcionalización confinada lateralmente de superficies de oro con MMTA utilizando la
técnica de microcontact printing (-CP) con sellos de Poly(dimethylsiloxane) PDMS
impregnados en la concentración óptima de la solución molecular. Un arduo trabajo de
pruebas han llevado a concluir la metodología adecuada para obtener películas de una o
dos alturas, cuya terminación consecuentemente es diferente (COOH o SH)
proporcionando diferente respuesta tanto en propiedades tribológicas (fricción) como
en propiedades electrónicas (corriente y potencial de superficie), cuyos resultados son
presentados en los capítulos 4 y 5. Algunas de las novedades más resaltables implican la diferenciación y establecimiento de la transición ente mecanismos de transporte (e.g.
túnel coherente a bajos voltajes y Fowler-Nordheim a mayores campos) a través de las
películas y en función del espesor de la película y de la fuerza aplicada.
El capítulo 6 esta dedicado al segundo sistema modelo, el óxido tipo perovskita STO, es
el substrato por excelencia para el crecimiento de óxidos complejos. La estructura
cristalina de estos óxidos, con fórmula general ABO3 contiene planos alternados de
composiciones atómicas AO (A=Sr) y BO2 (B=Ti) de tal manera que las superficies (001)
pueden tener esas dos posibles terminaciones químicas. Durante la tesis se ha puesto en
evidencia que la terminación de la superficie (dependiente del modo de obtención) es
determinante, por ejemplo, en la secuencia de empaquetamiento de películas
depositadas o en la reactividad de la propia superficie. Como principal conclusión que
obtener superficies SrO(001) y TiO2(001) bien caracterizadas es de gran importancia. En
coordinación con el grupo del Prof. Fontcuberta se ha demostrado que, variando las
condiciones de tratamientos térmicos (temperatura y tiempo de calentamiento) a que
se someten los cristales, se puede controlar la coexistencia y separación espacial de las
dos terminaciones en la misma superficie, obteniendo patrones químicos a escala
nanométrica. Y, en particular ha permitido el crecimiento selectivo tanto de películas
delgadas de óxidos funcionales como para la obtención de materiales híbridos
orgánico/inorgánico mediante la adsorción selectiva de monocapas orgánicas
autoensambladas. Por último, la técnica PM-IRRAS fue empleada para la caracterización
de la película molecular MMTA obtenida con tratamiento térmico y líneas abiertas de
trabajo de investigación para futuros estudios de crecimiento selectivo usando metalorgánicos
(dinuclear copper (II) acetate complexes (Cu2(CH3COO)4 2H2O)) son expuestos
en el capítulo 7.
El trabajo presentado en esta tesis doctoral evidencia que la estrategia combinada de
diferentes modos de microscopía de fuerzas de barrido (Scanning Force Microscopy,
SFM) en condiciones de ambiente controladas es la adecuada para, tanto para SAMs
como substratos de STO, determinar las características superficiales a nivel de estructura
molecular y morfología con gran precisión y obtener, simultáneamente, la información a
escala nanométrica de las propiedades tribológicas (estabilidad mecánica, fricción) y
electrónicas (transporte, potencial de superficie) de las superficies modelo bajo estudio.
De tal modo, como novedad a destacar en conjunto, se ha establecido la correlación
entre las características estructurales y las propiedades de las superficies en el marco
del transporte electrónico (C-SFM) para diferentes morfologías dependiendo del método
de obtención, y de cómo la terminación superficial modifica los potenciales de contacto
superficiales de los substratos de partida (Au en el caso de SAMs y el “as-received” STO),
mediante Kelvin Probe Force Microscopy (KPFM).The discovery of new and novel materials, process and phenomena at the nanoscale, as well as the new experimental and theoretical methods provide opportunities for the development of innovative nanosystems. Nature shows how builds macroscopic objects from small molecular building blocks with de ned shapes, properties, high order and degree of structural control in atomic scale materials. Under this evidence, nowadays is possible to assemble any kind of device or functional system, ranging from functional surfaces materials. This attractive concept is presented to pro t from the order of the arrangement of molecules or inorganic surfaces in well-ordered patterns to interlink the molecular or building block to other macro-systems in a bottom-up strategy. The present work lies within the scope of the mechanical and electrical characterization of functional surfaces, organics and inorganics, at the nanoscale by using the Scanning Force Microscopy (SFM) with their modes Friction Force Microscopy (FFM), Conductive Scanning Force Microscopy (C-SFM) and Kelvin Probe Force Microcopy (KPFM) which comprises of 7 chapters. Chapter 2 introduces the fundamental description about the technique, instrumentation and components for the data acquisition. A description of the main operation modes and the forces that can be measured is presented. The rst experimental part of this work describes the sample preparation, protocols and strategies to obtain layers or multilayers of a -conjugated organic aromatic thiol anchored on a gold surface. Chapter 3 describes the morphological characterization of Self Assembled Monolayers of the aromatic thiol mercapto-methyl terphenyl carboxylic acid (MMTA) for solutions using di erent solvents, concentrations and their in uence on the molecular packing. We show how to control the self-assembly and the formation of 3D structures from the aromatic thiol adsorbed on Au(111) and patterned gold surfaces by means of microcontact-printing ( CP). Moreover, we present how to control the size of the 3D structures by using a thermal treatment. The chapter 4 describes the tribological studies mainly on low and tall islands obtained by using di erent solvents after annealing. Chapter 5 shows the electronic transport measurements carried out on the MMTA molecular lms obtained with or without annealing. Complementary studies of KPFM (Kelvin Probe Force Microscopy) were mainly performed at low relative humidity over these surfaces. Chapter 6 is devoted to study the inorganic surface of complex oxides type perovskite, case STO(001), as a functional surface model by exploding the presence of both TiO2 and SrO chemical terminations. It is known that both terminations are presents in a random distribution in as-received surfaces, however under annealing chemical segregation can appear. We show that SrTiO3 surfaces can be used as a versatile template for growing ordered organic and inorganic nanostructures. Finally in chapter 7 we will present the characterization of the MMTA lms after annealing by means of the PM-IRRAS technique. A rst attempt of selective growth with dinuclear copper(II) acetate complexes (Cu2(CH3COO)4 2H2O) on the MMTA islands is studied by SFM. This chapter gives an outlook for the future implication of the selective growth on di erentiate chemical terminations.

This work was divided into three chapters; the first one was carried out for identifying secondary metabolites classes on three forage legumes: Pueraria phaseoloides (puero), Macrotyloma axillare (archer) and Neonotonia wightii (perennial soybean). These sorts of metabolites when present in plants may cause to animal adverse effects resulting ingestion and digestion decreasement and nutrients bioavailabity named antinutritional factors as well as may systematically induce to animal or herd performance decreasement. For this stud, phytochemical prospection, Nuclear Magnetic Resonance Analysis (NMRA) and Infrared Spectroscopy (IS) were performed. Following secondary metabolites classes: organic acids, reducing sugars, depsidians and depsidones, coumarine derivatives, steroids and triterpenoids, saponins, cardiac glycosides, saccharides and tannins on three forage legumes species were identified. Puero e perennial soybean for alkaloids presence were compatible. According bibliographic references, secondary metabolites classes have presented antinutritional effects compounds, some of totally dependent on intake and specie like reducing sugars and saccharides responsible for antinutritional effects on monogastric animals as well. The second chapter of this survey was carried out for quantifying condensed tannin content by Stiasny Reaction and for evaluating puero, archer and perennial soybean in vitro foam stability. For tannin quantification separated portions of entire plant, leaves, and stem by Simple Randomized Design with legumes allocated on subdivided parcels and portions on subparcels was used. By analysis of covariance, obtained result average, as well as interactions effects between legumes and portions by Tukey Test (P<0.05) were achieved. In vitro foam stability and yielding evaluation due to produced foam by legumes considered ruminant foamy meteorism potential etiological agent was performed. Simple Randomized Design consisting by subdivided parcels with three replications each was carried out where portions were composed by entire plant, leaves and stem as well as crude methanol extract related to parcels and remaining time (0, 5, 10, 30 and 60 minutes) for monitoring volume to subparcels. By Tukey Test (P<0.05) each portion averages within each time were compared and by analysis of variance results related to volume and remaining time were submitted to. By statistical analysis of Regression, saved volume effect during time and legumes interaction and checking time were evaluated as well as foam stability interaction in relation to remaining foam was estimated. Condensed tannin content ranged from 1 to 1.6%. In regard to perennial soybean and archer, foam stability produced by entire plant, leaves, stem and legumes methanol extract was considered constant, nevertheless puero showed significative result, creating the following regression equations y= -2.0111x 44.984 for leaf; y= -2.4x 37.957 for stem; y= -2.9049 x 31.779 for plant entire and y= -15.383x 125.31 for methanol extract. The aim of third chapter was to evaluate fungi association to legumes: Pueraria phaseoloides (puero), Neonotonia wightii (perennial soybean), Macrotyloma axillare (archer), Calopogonium mucunoides (calopo) and Arachis pintoi cv Amarillo (pinto), however, due to substances over legumes leaves presenting disgusting feature they have been considered unappropriate to animal feeding. According Barnett and hunter (1990) and Pitt and Hocking (1997) fungi amorphous reproduction elements were used. For fungi macroscopic and microscopic identification, Imprint tape technique, NaOH and blue cotton were used. The following fungi: Alternaria spp, Phitomyces chartarum, Nigrospora spp, Cladosporium spp, Mucor spp, Fusarium spp, Pseudomicrodochium spp, Tetraploa spp, Acremonium spp, Aspergillus niger, Curvularia spp and Micelia sterilia were reported, at all.
Este trabalho foi dividido em tr?s cap?tulos, o primeiro realizou-se com o objetivo de identificar as classes de metab?litos secund?rios presentes em tr?s leguminosas forrageiras Pueraria phaseoloides (kudzu tropical), Macrotyloma axillare (macrotiloma) e Neonotonia wightii (soja perene). Metab?litos estes, que quando presentes em plantas podem provocar efeitos adversos ao animal ocasionando diminui??o na ingest?o, digest?o e biodisponibilidade de nutrientes os que lhes conferem a denomina??o de fatores antinutricionais, estes efeitos podem repercutir de forma sist?mica acarretando diminui??o do desempenho animal ou rebanho. Para este estudo foi realizada a prospec??o fitoqu?mica, an?lise de Resson?ncia Magn?tica Nuclear de Hidrog?nio (RMN 1H) e Espectroscopia no Infravermelho (IV). Foram identificadas as seguintes classes de metab?litos secund?rios: ?cidos org?nicos, a??cares redutores, deps?dios e depsidonas, derivados da cumarina, ester?ides e triterpen?ides, saponinas, glicos?deos card?acos, sacar?deos e taninos nas tr?s esp?cies estudadas. O kudzu tropical e soja perene apresentaram ainda sinais compat?veis para a presen?a de alcaloides. As classes de metab?litos secund?rios estudadas apresentam compostos com efeitos antinutricionais para os animais, alguns destes efeitos s?o dependentes da quantidade ingerida e da esp?cie animal como o caso dos sacar?deos e ac?cares redutores que possuem efeitos antinutricionais em monog?stricos segundo literaturas consultadas. O segundo cap?tulo deste trabalho teve como objetivo quantificar o teor de tanino condensado atrav?s da Rea??o de Stiasny e avaliar a estabilidade in vitro da espuma formada pelas leguminosas, kudzu tropical, macrotiloma e soja perene. Para a quantifica??o do tanino, foram tomados em separados as por??es, planta inteira, folhas e haste, utilizou-se um delineamento inteiramente casualizado com parcelas subdivididas alocando-se as leguminosas nas parcelas e as por??es nas subparcelas. A m?dia do resultado obtido foi submetida ? an?lise de vari?ncia e comparadas pelo Teste de Tukey (P<0,05), os efeitos das intera??es entre leguminosas e por??es foram desdobrados pelo teste de Tukey (P<0,05) a avalia??o da produ??o e estabilidade da espuma in vitro foi realizada devido ? espuma produzida por leguminosas ser referida como poss?vel agente etiol?gico do meteorismo espumoso em ruminantes. Neste estudo utilizou-se o delineamento inteiramente casualizado em parcelas subdivididas com tr?s repeti??es cada, onde as por??es compostas por planta inteira, folhas, e haste e o extratos metan?lico bruto foram consideradas as parcelas e o tempo de repouso (0, 5, 10, 30 e 60min) onde aferiu-se o volume as subparcelas. O resultado referente ao volume produzido e conservado durante o tempo de repouso foi submetido ? an?lise de vari?ncia e as m?dias de cada por??o dentro de cada tempo foram comparadas pelo teste de Tukey (P<0.05) o efeito do volume conservado durante o tempo e a intera??o entre leguminosas e tempo de aferi??o foi desdobrados pela an?lise de regress?o e a intera??o da estabilidade da espuma formada foi avaliada em fun??o da porcentagem de espuma remanescente. Como resultado deste estudo o teor de tanino condensado variou de 1 a 1,6%. Quanto ? estabilidade da espuma produzida pelas por??es planta inteira, folha, haste e extrato metan?lico das leguminosas foi considerada est?vel para as por??es referentes ? soja perene e macrotiloma, entretanto o kudzu apresentou um resultado significativo para a estabilidade da espuma para as quatros por??es em estudos, gerando as equa??es de regress?o y=-2,0111x44,984 para a por??o folha; y= -2,4x37,957 para a por??o haste; y= -2,9049x31,779 para a por??o planta inteira e para o extrato metan?lico a equa??o y= -15,383x 125,31. O objetivo da realiza??o do terceiro cap?tulo deste estudo foi avaliar a associa??o de fungos com as leguminosas: Pueraria phaseoloides (kudzu tropical), Neonotonia wightii (soja perene), Macrotyloma axillare (macrotiloma), Calopogonium mucunoides (calopog?nio) e Arachis pintoi cv.amarillo (amendoim forrageiro) devido ? presen?a de subst?ncias encontradas depositadas sobre as folhas das leguminosas as quais conferiram aspecto repugnante para inclus?o na alimenta??o animal. Para esta avalia??o foram utilizados os elementos de reprodu??o amorfas dos fungos de acordo com as metodologias de Barnett e Hunter, (1990) e Pitt e Hocking, (1997). Na identifica??o observaram-se a macroscopia e microscopia dos fungos utilizando Imprint com fitas adesivas ou lam?nulas de vidro, NaOH e Azul de algod?o, diretamente do material obtido das leguminosas e das col?nias desenvolvidas em Agar Sabouraud Dextrose e Agar Simples, sendo identificados os fungos Alternaria spp, Phitomyces chartarum, Nigrospora spp, Cladosporium spp, Mucor spp, Fusarium spp, Pseudomicrodochium spp, Tetraploa spp, Acremonium spp, Aspergillus niger, Curvularia spp e Mic?lia ster?lia.

A Caatinga e a Floresta Atl?ntica apresentam ampla riqueza de esp?cies, as quais podem atender ?s exig?ncias para diversos usos. Considerando o atual n?vel de degrada??o da vegeta??o do Rio Grande do Norte, e o crescente uso de esp?cies ex?ticas, torna-se urgente a execu??o de a??es que visem a conserva??o da biodiversidade desses biomas. Nessa perspectiva, utilizar esp?cies vegetais aut?ctones na arboriza??o das cidades acaba por se caracterizar em um instrumento de conserva??o e de valoriza??o da biodiversidade local. Diante desse contexto, o objetivo geral do presente trabalho ? reunir e fornecer informa??es acerca das esp?cies arb?reas nativas ornamentais no estado com o intuito de fomentar e difundir o seu uso na arboriza??o urbana. Como objetivos espec?ficos o trabalho possui: (1) avaliar e verificar a demanda e os custos de manuten??o da arboriza??o urbana nativa e ex?tica, comparativamente, com base em dados obtidos no estado (Cap. 1); (2) Fornecer uma listagem de esp?cies arb?reas nativas ornamentais do estado, incluindo esp?cies com uso j? difundido e sugerindo novos elementos com potencial ornamental (Cap. 2); e (3) produzir um guia de esp?cies arb?reas da flora nativa como um meio de divulga??o dos resultados obtidos com conte?do acess?vel ? sociedade. A an?lise da manuten??o da arboriza??o urbana foi realizada no Campus Central da UFRN, para o levantamento das esp?cies nativas arb?reas ornamentais foram realizadas expedi??es a fragmentos vegetais no estado, al?m de levantamento da literatura especializada. Como resultado, verificou-se evidentes menores custos e menor demanda de servi?os para manuten??o da vegeta??o nativa, evidenciando a vis?vel vantagem no uso de uma arboriza??o de composi??o flor?stica regionalizada. O levantamento das esp?cies nativas arb?reas ornamentais levou ? sele??o de 95 esp?cies distribu?das em 30 fam?lias, sendo 17 esp?cies (17,35%) ocorrendo exclusivamente na Caatinga, 27 esp?cies (25,55%) na Mata Atl?ntica e mais da metade da riqueza considerada (55,10%) ocorrendo em ambos os biomas, o que proporciona uma diversidade dispon?vel para a composi??o da arboriza??o urbana, tanto para cidades situadas no dom?nio da Mata Atl?ntica (81 spp.) como da Caatinga (71 spp.). A partir desses resultados, elaborou-se uma proposta de manual de reconhecimento e cultivo de ?rvores nativas, consistindo na etapa inicial no processo de valoriza??o do potencial flor?stico existente com o intuito de auxiliar o desenvolvimento de uma perspectiva ambiental regionalizada da gest?o urbana no estado
The Caatinga and Atlantic Forest exhibit great species richness, which can attend requirements for various uses. Considering the current level of degradation of vegetation in Rio Grande do Norte, and the increasing use of exotic species, it is urgent to perform actions for the conservation of these biomes. From this perspective, using native plant species in the urban forestry becomes an instrument for the conservation and enhancement of local biodiversity. In this context, the general objective of this study is to gather and provide information about the ornamental native tree species in the state in order to promote and disseminate their use in urban areas. Specific aims of this work are: (1) evaluate and verify the demand and maintenance costs of native and exotic urban forestry, comparatively, with data obtained in the state (Cap. 1); (2) Provide a ornamental native tree species list in the state, including species already widespread use and suggesting new elements with ornamental potential (Cap. 2); and (3) produce a guide of native tree species as a means of disseminating the results obtained in a way accessible to the society. Analysis of maintenance of urban trees was performed at the UFRN's Central Campus, and the ornamental native tree species survey was carried out through literature survey combined with expeditions to forest fragments in the state. As a result, it was obvious that the maintenance of native vegetation resulted in lower costs and least demand for services highlighting the visible advantage in using a afforestation with regionalized floristic composition. The survey of ornamental native tree species led to the selection of 95 species belonging to 30 families, 17 species (17.35%) occurring exclusively in the Caatinga, 27 species (25.55%) in the Atlantic Forest and more than half (55.10%) occurring in both biomes, which provides a good selection available for the composition of urban forestry, both for cities located in the area of Atlantic Forest (81 spp.) or for those located in the Caatinga (71 spp.). From these results, a guide for the recognition and cultivation of native ornamental trees was prepared, consisting in the initial step in the enhancement of existing floristic potential value with the aim to assist in the development of a regionalized perspective of urban environmental management in the state

No Brasil e no mundo, a evolu??o do setor de telecomunica??es tem sido cada vez mais requisitada como uma clara consequ?ncia do crescimento exponencial da demanda por sistemas de comunica??o sem fio. Neste cen?rio, a integra??o de m?ltiplos padr?es wireless em uma ?nica plataforma, antena reconfigur?vel, tamb?m conhecida como antena sintoniz?vel, est? atraindo muita aten??o. Estruturas metasurfaces t?m sido extensivamente utilizadas nos ?ltimos anos para alcan?ar o aperfei?oamento de antenas, dentre eles, a reconfigura??o. Uma metasuperf?cie (tamb?m referida como um metafilm) ? o equivalente de uma superf?cie metamaterial. Mais precisamente, um metafilm ? uma superf?cie com uma distribui??o de pequenos dispersores arranjados ao longo de uma regi?o do espa?o, de modo a obter comportamentos eletromagn?ticos desej?veis. Para muitas aplica??es, metasuperf?cies podem ser usadas no lugar de metamateriais, pois possuem como vantagem principal ocupar menos espa?o f?sico do que as estruturas tridimensionais dos metamateriais, oferecendo a possibilidade de perdas reduzidas, o que tem gerado grande interesse. Neste contexto, esta disserta??o de mestrado apresenta a simula??o, o projeto e a implementa??o de estruturas de antenas planares acopladas a estruturas de metasurfaces a fim de realizar reconfigura??o de antenas em frequ?ncia, polariza??o e multibanda, para aplica??es em comunica??es sem fio. A an?lise das estruturas das antenas ? realizada com o aux?lio de ferramentas computacionais. Prot?tipos s?o constru?dos e medidos, para fins de comprova??o experimental. Os resultados obtidos em medi??es e simula??es apresentam uma boa concord?ncia.
All over the world, the evolution of the technological apparatus for telecommunications systems has been increasingly required, as a clear consequence of the exponentially growth in the demand for wireless communication services. Therefore, the integration of multiple wireless standards on a single platform, like a reconfigurable antenna, also known as tunable antenna, is attracting much attention. Metasurfaces structures have been extensively used in recent years to improve the performance of planar antennas for wireless applications, including reconfiguration. A metasurface (also referred to as a metafilm) is the equivalent of a metamateriaI surface. More precisely, one metafilm is a surface with a distribution of small scatterers arranged along a region of space, to achieve desirable electromagnetic behaviors. For many applications, metasurfaces can be used in place of metamaterials because they have the advantage of taking up less physical space than the three-dimensional structures of metamaterials, offering the possibility of reduced losses, which has generated great interest. Therefore, this master thesis presents the simulation, design and implementation of planar antenna structures coupled to metasurfaces structures in order to reconfigure frequency, polarization and multiband antennas for wireless communications applications. The analysis of the antenna structures is performed with the aid of computational tools. Prototypes are fabricated and measured for experimental verification purpose. Simulations and measurements results are in good agreement.

The objective of this study was to determine if eye and head based psychophysiological cues can be used to maintain screener vigilance levels during long duration tasks. In two parts, this study first explored which cues are predictive of vigilance levels. The second part of the study developed a vigilance feedback system using the cues established in part one and compared the results of subjects using the feedback system with those subjects having received no feedback or those who received random feedback.In part one, 48 participants reviewed 600 simulated x-rays to determine if any hazardous items (guns or knives) were present. Individual vigilance levels were determined by scoring the number of correct detections during eight 5-minute periods (total study length = 40 minutes). Using an eye-tracking machine, four concurrent eye and head activity measures (blinks, saccades, pupil diameter, and head position) were used to model changes in vigilance level throughout a simulated baggage screening task. At the end of the study, changes in blink and saccade rates proved to be significant predictors of an individual's ability to detect the presence of these hazardous items among other non-significant baggage items.Part two required 126 participants equally distributed across three conditions to repeat the same screening task. For one condition the monitoring system, instead of passively recording the individual's cues, provided near real-time feedback of vigilance levels to a condition. Participants in other conditions received random feedback on their vigilance levels while a third group received no feedback. At the conclusion of the study the subjects who received the real-time feedback performed significantly better than those who received no feedback. However, they did not perform better than the subjects who received random feedback. Perhaps more significantly, the subjects who received random feedback, while performing better than the no feedback group, also experienced a significantly higher number of false detects.The results of this study indicate a vigilance feedback system based upon subject psychophysiological cues may be an effective method to maintain attention levels during long duration vigilance tasks while preventing a corresponding increase in error detection rates.

In this study, the fraction of the heterochromatin of the Apareiodon sp. chromosome W was isolated by microdissection with subsequent amplification by DOP-PCR. The sequences obtained were used in the procedure of the fluorescence in situ hybridization in Parodontidae species chromosomes. This probe was named WAp. Then, with this marker and others available, the study presented a molecular cytogenetic analysis in Parodontidae species present in different Brazilian hydrographic basin. The species analyzed were: Apareiodon sp., A. ibitiensis, A. vladii, A. piracicabae, A. vittatus, A. affinis, P. hilarii, P. moreirai, P. nasus and P. pongoensis. The results reveal closeness of the location of 18S rDNA marker found in Parodon species compared to the sister group Anostomidae. Still, it has been viewed a high identity chromosome pair bearing the rDNA 5S sites in all Parodontidae studied. Mapping of repetitive DNAs WAp and pPh2004 by fluorescence in situ hybridization in chromosomes of some species of Parodontidae permitted deduce the origin and differentiation of sex chromosome system ZZ/ZW from a inversion allocating proximal region WAp sites of a chromosome metacentric pair. These results allowed inferring that the sex chromosome system multiple ZZ/ZW1W2 of A. affinis can originate from one system ZW similar to that found in ancient populations of species P. hilarii. Thus, this work contributes to the understanding of development and diversification of the genome of some species of Parodontidae, mainly to the comprehension of the origin and sex chromosome differentiation.
Neste estudo, a fra??o heterocrom?tica do cromossomo W de Apareiodon sp. foi isolado por microdissec??o com posterior amplifica??o por DOP-PCR. As seq??ncias obtidas foram utilizadas no procedimento de hibrida??o in situ fluorescente em cromossomos de esp?cies de Parodontidae. Esta sonda foi denominada WAp. Assim, de posse deste marcador e de outros j? dispon?veis o trabalho apresentou uma an?lise de citogen?tica molecular em exemplares da fam?lia presentes em diferentes bacias hidrogr?ficas brasileiras. Foram analisadas as esp?cies: Apareiodon sp., A. ibitiensis, A. vladii, A. piracicabae, A. vittatus, A. affinis, P. hilarii, P. moreirai, P. nasus e P. pongoensis. Os resultados evidenciaram a proximidade da localiza??o do marcador do rDNA 18S encontrado em esp?cies de Parodon em compara??o ao grupo irm?o Anostomidae. Ainda, foi visualizado um alta identidade do par cromoss?mico portador dos s?tios de rDNA 5S em todos Parodontidae estudados. Com o mapeamento dos DNAs repetitivos WAp e pPh2004 por hibrida??o in situ fluorescente nos cromossomos de algumas esp?cies de Parodontidae foram lan?adas hip?teses de origem e diferencia??o do sistema de cromossomos sexuais ZZ/ZW a partir de uma invers?o alocando s?tios WAp em regi?o proximal de um par cromoss?mico metac?ntrico. Esses resultados permitiram inferir tamb?m que o sistema de cromossomos sexuais m?ltiplos ZZ/ZW1W2 de A. affinis pode ter origem de um sistema ZW similar ao encontrado em popula??es ancestrais da esp?cie P. hilarii. Assim, este trabalho contribui para o entendimento da evolu??o e diversifica??o do genoma de algumas esp?cies de Parodontidae, principalmente para o esclarecimento da origem e diferencia??o dos cromossomos sexuais.

Lippia (Verbenaceae) is a plant genus distributed throughout all Southern and Central America, and Tropical Africa. Approximately 60 species are endemic in Brazil and 22 are endemic in the state of Bahia. Lippia has a long history of use in traditional medicine, the most common use being in the treatment of respiratory diseases. Despite Lippia?s extensive history in treating diseases, little is known about its anticancer properties against brain and central nervous system tumors. This paper explores the anticancer potential of 5 species of Lippia from the state of Bahia (Brazil),Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoides and Lippia thymoides. To assess the cell viability of essential oils and methanol extracts derived from these species MTT assay was utilized. To assess the effects of the essential oils and methanol extracts on morphology of cancer cells a Nikon Ts-100 phase contrast microscope was used, and photos were taken with a Nikon E4300. All essential oils were evaluated at 0.1 mg.mL-1, 0.3 mg.mL-1, 0.5 mg.mL-1, and 1 mg.mL-1. All methanol extracts were evaluated at 1 ?g.mL-1, 10 ?g.mL-1, 100 ?g.mL-1, 500 ?g.mL-1, and 1000 ?g.mL-1. The ability to inhibit cell migration was assessed by wound heal assay. All methanol extracts were evaluated at 500 ?g.mL-1. All essential oils were evaluated at 0.1 mg.mL-1. To access the effects of essential oils and methanol extracts on the cell cycle flow cytometry was used. All methanol extracts were evaluated at 1000 ?g.mL-1. All essential oils were evaluated at 0.03 mg.mL-1. The essential oils derived from Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, and Lippia origanoides all drastically decreased the cell viability of the C6 cell line in a concentration dependent manner. The essential oil derived from Lippia thymoides increased cell viability in a concentration dependent manner. All of the methanol extracts appear to have the ability to abruptly decrease cell viability at either 500 ?g.mL-1 or 1000 ?g.mL-1 it. Lippia alnifolia and Lippia insignis both have the ability to significantly alter the morphology of the C6 cell line. Methanol extracts derived from Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoides and Lippia thymoides all significantly inhibit the migration of C6 cells at a concentration of 500 ?g.mL-1. Essential oils obtained from Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoides and Lippia thymoides significantly inhibited the migration of C6 cells at a concentration of 0.1 mg.mL-1. All methanol extracts and essential oils tested demonstrated the ability to induce some degree of nuclear fragmentation, vacuolization, and cytoplasmic swelling. These results indicate that the constituents of both the essential oils and methanol extracts should be isolated and their anticancer potential should be further explored.
Lippia (Verbenaceae) ? um g?nero de planta distribu?do pela Am?rica do Sul, Central e a ?frica Tropical. Aproximadamente 60 esp?cies s?o end?micas do Brasil e 22 s?o end?micas do estado da Bahia. Lippia tem uma longa hist?ria de uso na medicina tradicional, sendo o uso mais comum no tratamento de doen?as respirat?rias. Apesar da extensa hist?ria de Lippia no tratamento de doen?as, pouco se sabe sobre suas propriedades antitumorais contra tumores cerebrais. Este estudo buscou explorar o potencial antiglioma de ?leos essenciais e extratos metan?licos de Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoides e Lippia thymoides em c?lulas de glioma da linhagem C6. Para avaliar a viabilidade celular foram utilizados o ensaio do MTT. Os efeitos das amostras na morfologia de c?lulas cancerosas foram avaliados utilizando-se um microsc?pio de contraste de fase Nikon Ts-100 e fotos com uma Nikon E4300. Os ?leos essenciais foram avaliados nas concentra??es de 0,1 mg.mL-1, 0,3 mg.mL-1, 0,5 mg.mL-1 e 1 mg.mL-1 e os extratos de metanol a 1 ?g.mL-1, 10 ?g.mL-1, 100 ?g.mL-1, 500 ?g.mL-1 e 1000 ?g.mL-1. A capacidade de inibir a migra??o celular foi avaliada pelo ensaio de cicatriza??o da ferida, na qual os extratos foram avaliados a 500 ?g.mL-1 e os ?leos essenciais a 0,1 mg.mL-1. O ciclo celular foi avaliado na citometria de fluxo nas concentra??es de 1000 ug.mL-1 para os extratos e 0,03 mg.mL-1 para os ?leos essenciais. Os ?leos essenciais obtidos de Lippia alnifolia, Lippia insignis, Lippia lasiocalycina e Lippia origanoides reduziram drasticamente a viabilidade celular C6 de uma maneira concentrac?o-dependente. J? o ?leo essencial de Lippia thymoides aumentou a viabilidade celular de uma maneira concentrac?o-dependente. Todos os extratos de metanol parecem ter a capacidade de diminuir abruptamente a viabilidade celular em 500 ?g.mL-1 ou 1000 ?g.mL-1. Lippia alnifolia e Lippia insignis parecem ter a capacidade de alterar significativamente a morfologia da linha celular C6. Os extratos metan?licos de Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoides e Lippia thymoides inibem significativamente a migra??o de c?lulas C6 a uma concentra??o de 500 ?g.mL-1. Os ?leos essenciais de Lippia alnifolia, Lippia insignis, Lippia lasiocalycina, Lippia origanoidese Lippia thymoides inibem significativamente a migra??o de c?lulas C6 a uma concentra??o de 0,1 mg.mL-1. Todos os extratos metan?licos e ?leos essenciais testados demonstraram a capacidade de induzir algum grau de fragmenta??o nuclear, vacuoliza??o e incha?o citoplasm?tico.Estes resultados indicam que os constituintes dos ?leos essenciais e extratos metan?licos devem ser isolados e seu potencial anticancer?geno deve ser explorado.

Previous issue date: 2011-11-29Commercially pure Titanium (cp Ti) is a material largely used in orthopedic and dental implants due to its biocompatibility properties. Changes in the surface of cp Ti can determine the functional response of the cells such as facilitating implant fixation and stabilization, and increased roughness of the surface has been shown to improve adhesion and cellular proliferation. Various surface modification methods have been developed to increase roughness, such as mechanical, chemical, electrochemical and plasma treatment. An argon plasma treatment generates a surface that has good mechanical proprieties without chemical composition modification. Besides the topography, biological responses to the implant contribute significantly to its success. Oxidative stress induced by the biomaterials is considered one of the major causes of implant failure. For this reason the oxidative potential of titanium surfaces subjected to plasma treatment was evaluated on this work. CHO-k1 cells were cultivated on smooth or roughed Ti disks, and after three days, the redox balance was investigated measuring reactive oxygen species (ROS) generation, total antioxidant capacity and biomarkers of ROS attack. The results showed cells grown on titanium surfaces are subjected to intracellular oxidative stress due to hydrogen peroxide generation. Titanium discs subjected to the plasma treatment induced less oxidative stress than the untreated ones, which resulted in improved cellular ability. Our data suggest that plasma treated titanium may be a more biocompatible biomaterial.
O Tit?nio comercialmente puro (cpTi) ? amplamente utilizado em implantes ortop?dicos e dentais gra?as ?s suas propriedades f?sico-qu?micas. Mudan?as na superf?cie do cpTi podem determinar respostas funcionais nas c?lulas influenciando a fixa??o e estabiliza??o do implante. Muitos m?todos de modifica??o na superf?cie podem ser aplicados para aumentar a rugosidade como, por exemplo, tratamentos mec?nicos, qu?micos, eletroqu?micos e a plasma. Este ?ltimo, quando realizado em atmosfera de arg?nio gera uma superf?cie rugosa com boas propriedades mec?nicas sem alterar a composi??o qu?mica do material. Superf?cies rugosas geralmente s?o mais biocompat?veis que as lisas, pois esse tipo de topografia facilita os processos de ades?o e prolifera??o celular. Al?m da topografia, as rea??es biol?gicas desencadeadas em resposta ao implante contribuem de forma significativa para o sucesso do mesmo. Dentre estas rea??es, o estresse oxidativo tem sido apontado como um dos principais respons?veis por falhas na implanta??o. Diante do exposto, o potencial oxidativo das superf?cies de tit?nio tratadas e n?o tratadas a plasma em atmosfera de arg?nio foi avaliado neste trabalho. Para tanto, c?lulas CHOk1 foram cultivadas sobre as superf?cies de tit?nio (tratadas e n?o tratadas). Ap?s tr?s dias de cultivo o potencial oxidativo foi investigado por meio da quantifica??o de esp?cies reativas, an?lise da capacidade antioxidante e an?lise de biomarcadores de dano oxidativo (lipoperoxida??o, carbonila??o prot?ica e oxida??o das bases do DNA). Os resultados obtidos indicam que ambas as superf?cies de tit?nio induzem estresse oxidativo, sendo o per?xido de hidrog?nio a principal esp?cie envolvida. O tratamento a plasma reduziu os danos oxidativos e promoveu melhora na habilidade celular em responder ao estresse oxidativo. Deste modo, a modifica??o da superf?cie de tit?nio atrav?s do tratamento a plasma pode ser uma alternativa para a obten??o de um material com melhor biocompatibilidade.
