The main task of diploma is creating a sacral object and community centre of Salesians in Brno-Líšeň. A construction of the Salesian complex started in 1998. As a result, the whole complex of institution got to the district of Brno-Lisen with the help of the endowment fund for youth. The Congregation focuses on the methods of educating the youth of Don Bosco, the father and teacher of the youth, the first head of the Salesian. The creation of a church is a very desirable step for the Salesian Center, because Masses are currently being celebrated in the existing building in the gym, where not everything is needed to carry out of the event. The church should be developed in the vicinity of Salesian centre and has to be available for a wide range of societies. The architectural project includes the designing of church, parish building and enviroment. The form and view of the complex suit to this environmental area and react on its entire structure. The object consists of two forms, which are connected by the horizontal communication. In the middle of the Salesian complex, there is a semi-open area. The first object is a church with a capacity of approximately 200 hundred visitors, the second object is a parish building, which perform the functions of administration with multifunction space for the exhibitions, aparmtments and offices for its employees.

Tutkimukseni käsittelee oululaisia alakulttuurilehtiä. Primääriaineistoni koostuu seuraavista lehdistä: Tilt Zeitung (1979–1980), Anonyymi mustetahra (1979–1981), Kupla (1981–1983), Ruuvari (1988–1995) ja Esa (2005–). Tilt Zeitung ja Anonyymi mustetahra kytkeytyvät 1970-luvun lopulla ja 1980-luvun alkupuolella kukoistaneisiin paikallisiin punk- ja uusi aalto -alakulttuureihin. Lehdet välittävät tietoa alakulttuurin sisällä ja kritisoivat valtakulttuurin instituutioita. Sarjakuvalehdet Kupla ja Ruuvari pyrkivät vahvistamaan suomalaisen sarjakuvan kehnoa asemaa julkaisemalla kotimaista ja paikallista sarjakuvaa 1980-luvulta 1990-luvun puoliväliin saakka. Esa on nuorten aikuisten miesten elämäntyyliä kuvaava alakulttuurilehti, joka on yhteydessä paikalliseen skeittikulttuuriin esitellen myös graffitia ja katutaidetta 2000-luvun puolelta. Tutkimukseni tärkein tehtävä on dokumentaarinen: kirjoittamattoman paikalliskulttuurin tallentaminen ja esitteleminen. Toisena merkittävänä osuutena tutkimuksessa on alakulttuurilehtien asettaminen kulttuuriseen kontekstiin. Kolmantena, koko tutkimuksen läpi jatkuvana teemana, on vastakulttuuriset sisällöt ja keinot oululaisissa alakulttuurilehdissä, joita pyrin kartoittamaan ja hahmottelemaan työkaluja niiden tulkitsemiseen.
Aiheesta ei löydy aiempaa tieteellistä tutkimusta, eikä siitä ole kirjoitettu syventävästi myöskään lehdistössä tai kulttuurihistoriaa käsittelevissä teoksissa. Keskeisenä kysymyksenä on alakulttuurilehtien kulttuurisen tilan määrittely, jota selvitän tekijöiden haastattelujen, sanomalehtijuttujen ja lehtiin liittyvien alakulttuurien taustojen avulla. Kerron myös zine-lehtien historiasta yleisesti ja sitten tarkemmin Suomen zine-julkaisujen kahdesta huippukaudesta: suomalaisesta undergroundista (n.1967–1970) ja punk-kulttuurin mukana tuomasta pienlehtivillityksestä, joka jatkui 1970-luvun lopulta 1980-luvulle asti. Tekemäni haastattelut paljastavat uutta tietoa alakulttuurilehtiin liittyvien tietojen lisäksi myös punk-, sarjakuva-, skeitti- ja graffitikulttuureista Oulussa.
Lähestymistapani yhdistelee kulttuurintutkimuksen, sosiologian, kulttuuriantropologian ja taiteentutkimuksen keinoja. Tutkimieni lehtien asema kulttuurin kentällä on alakulttuurinen ja ne toimivat valtakulttuurin sivussa vahvasti omaperäisiä toimituskäytäntöjä hyödyntäen. Osallistuva DIY eli Do It Yourself -asenne ja bricolage eli käsillä olevien ainesten luova hyödyntäminen ilmenevät niin lehtien sisällöissä kuin tekotavoissakin. Alakulttuurilehtien ilmaisullinen vapaus peilautuu valtakulttuurin tabuja, sensuuria ja skandaaleja aiheuttavia sisältöjä vasten. Vastakulttuuriset sisällöt ilmenevät tutkimusaineistossani muun muassa valtainstituutioiden ja normien kritisointina sekä ruumiillisuuden vapaana kuvauksena. Käsityksiä hyvästä mausta rikotaan karnevalistisella hulluttelulla, joka näkyy eritteiden ja groteskin ruumiin kuvauksen lisäksi myös splatter-genrelle ominaisena graafisena ruumiin silpomisena ja veren kuvauksena Valtakulttuurin genrejä ja hahmoja ”kaapataan” ja esitetään uusissa konteksteissa, gonzo-journalismi vie toimittajan osalliseksi tapahtumia ja dadaistiset vaikutteet näkyvät spontaanissa ja hyppivässä tekstin etenemisessä. Vastakulttuuriset sisällöt ja keinot haastavat valtakulttuurin diskursiivista valtaa ja luovat toisinaan uusia ilmaisutapoja ja tyylejä.
Alakulttuurilehtien tekijät ammentavat sisältöä lehtiinsä omista alakulttuureistaan ja elämäntyyleistään. Lehdet muodostavat kuvan alakulttuureista ja ihmisistä, joille ne ovat tarjonneet vapaan ilmaisukanavan. Alakulttuurilehtien yksi ansio on alakulttuurin määrittely sisältäpäin ja äänen antaminen virallisten valtarakennelmien sivussa toimiville alakulttuurin jäsenille. Itsenäiset tekotavat mahdollistavat lehtien tekemisen ympäröivistä yhteiskunnallisista ja kulttuurisista olosuhteista riippumatta.

Neste trabalho nós estudamos os expoentes de Lyapunov de aplicações f : Td → Td homotópicas a uma aplicação Anosov linear e a continuidade absoluta de folheações. Nós mostramos para algumas classes de homotopia de aplicações que a soma dos expoentes de Lyapunov está limitado pela soma dos expoentes de Lyapunov da aplicação Anosov linear. Além disso, admitindo uma propriedade conhecida como densidade uniformemente limitada (UBD) nas folheações, mostramos uma igualdade entre a soma dos expoentes de Lyapunov de f e do Anosov linear. Também construímos um conjunto C1 aberto de difeomorfismos parcialmente hiperbólicos do toro T4, preservando volume, com folheação central bidimensional não compacta e não absolutamente contínua. Ainda construímos um exemplo parcialmente hiperbólico com folhas centrais bidimensionais, não compactas onde a desintegração do volume ao longo da folheação central não é nem Lebesgue nem atômica.In this work we study the Lyapunov exponents of maps f : Td → Td homotopic to a linear Anosov map. We proof for some homotopic classes of maps which the sum of Lyapunov exponents is bounded by the sum of the Lyapunov exponents of the linear Anosov map. Moreover, by assuming a property known as uniformly bounded density (UBD) in the foliations, we show an equality between the sum of the Lyapunov exponents of f and the linear Anosov. We also construct an C1 open set of volume preserving partially hyperbolic diffeomorphisms with non compact two dimensional center foliation and non absolutely continuous. We still build an example of partially hyperbolic diffeomorphism with non compact bidimensional center leaves where the disintegration of volume along the center foliation is neither Lebesgue nor atomic.

Esta investigação tem como objetivo central discutir peculiaridades da historiografia da música popular brasileira na primeira metade do século XX, por meio da trajetória de um de seus precursores: Almirante (Henrique Foreis Domingues, Rio de Janeiro, 1908-1980). Além de ter se tornado conhecido como a mais alta patente do rádio já no final da década de 1930, em razão de sua importância para a profissionalização e diversificação da programação radiofônica, Almirante teve papel fundamental nos estudos sobre a história da música popular brasileira, integrando o que podemos chamar de sua primeira geração de historiadores. Seus programas eram caracterizados pela organização e preocupação em conferir valor científico aos temas abordados que abrangiam do folclore à música urbana difundida pelos meios de comunicação em massa , e baseados em pesquisas que contribuíram para a formação de um vasto arquivo sobre música popular, o qual deu origem e sentido ao Museu da Imagem e do Som (MIS-RJ), em 1965. Almirante, junto com outros nomes de sua geração, foi responsável pela seleção, organização, compilação, e arquivamento de registros, estabelecendo hierarquias, determinando recortes, problemas e, assim, um discurso fundador em torno da história da música popular brasileira. Esta historiografia é singular sobretudo porque foi desenvolvida e difundida nos meios de comunicação em massa. É também de certa maneira inovadora na tentativa de compreender a importância da música popular para a formação das identidades culturais urbanas, criando paradigmas e precedendo as investidas acadêmicas, por já recorrer a novas temáticas, objetos e fontes antes que os historiadores se ocupassem disso. Este trabalho propõe, assim, abordar a obra de Almirante do ponto de vista de sua contribuição à historiografia da música popular, através de sua atuação no rádio, de 1938 a 1958.This research has as its main goal to argue particularities of the historiography on Brazilian popular music in the first half of the XX century, by analyzing the trajectory of one of its precursors: Almirante (Foreis Domingues, Rio de Janeiro, 1908-1980). Besides being known as the highest rank in the radio in the late 30s, due to his roles in the professionalization and diversification of radio broadcasts, Almirante also had a central role in the development of studies on the history of Brazilian popular music, being part of what we can call as the first generation of historians on the subject. His broadcasts were known by their organization, as well as for their concern in treating the subjects presented in a scientific manner subjects ranging from folklore to the more urban music, diffused by the mass media. These broadcasts were based on researches whose results helped forming a vast archive on popular music, which would be the basis for the formation of the Museu da Imagem e do Som (Museum of Image and Sound MIS-RJ), in 1965. Almirante, together with other personalities of his generation, was responsible for the process of selecting, organizing, compiling, and archiving the records, establishing priorities, determining the research approaches and questions and, thus, defining a founding discourse on the history of Brazilian popular music. This historiography is unique in the sense that it was developed and disseminated within and by the mass-media. It is also innovative, in a certain way, in its effort to understand the importance of popular music in the forming of urban cultural identities, creating paradigms and preceding the academic researches in this field. This is due to the fact that these researches worked with new subjects, sources and objects long before \'professional\' historians worked with them. Thus, this work aims to study the works of Almirante from the point of view of their contribution to the historiography of popular music, through his performance in the radio, from 1938 to 1958.

This work a studied the high energy milling effect in microstructure and magnetic properties of the WC-10wt.%Co composite. The composite powders were prepared by mechanical mixed and milled at 2 hours, 100 hours, 200 hours and 300 hours in planetary milling. After this process the composite were compacted in stainless steel die with cylindrical county of 10 mm of diameter, at pressure 200 Mpa and sintered in a resistive furnace in argon atmosphere at 1400 oC for 5 min. The sintered composite were cutted, inlaid, sandpapered, and polished. The microestrutural parameters of the composite was analyzed by X-ray diffraction, scanning electronic microscopy, optical microscopy, hardness, magnetic propriety and Rietveld method analyze. The results shows, with milling time increase the particle size decrease, it possibility minor temperature of sintering. The increase of milling time caused allotropic transformation in cobalt phase and cold welding between particles. The cold welding caused the formation of the particle composite. The X-ray diffraction pattern of composite powders shows the WC peaks intensity decrease with the milling time increase. The X-ray diffraction pattern of the composite sintered samples shows the other phases. The magnetic measurements detected a significant increase in the coercitive field and a decrease in the saturation magnetization with milling time increase. The increase coercitive field it was also verified with decrease grain size with milling time increase. For the composite powders the increase coercitive field it was verified with particle size reduction and saturation magnetization variation is relate with the variation of free cobalt. The Rietveld method analyze shows at milling time increase the mean crystalline size of WC, and Co-cfc phases in composite sintered sample are higher than in composite powders. The mean crystallite size of Co-hc phase in composite powders is higher than in composite sintered sample. The mean lattice strains of WC, Co-hc and Co-cfc phases in composite powders are higher than in composite sintered samples. The cells parameters of the composite powder decrease at milling time increase this effect came from the particle size reduction at milling time increase. In sintered composite the cells parameters is constant with milling time increase
O presente trabalho estudou o efeito da moagem de alta energia nos par?metros microestruturais e nas propriedades magn?ticas do comp?sito WC-10%pCo. Os p?s comp?sitos foram processados em moinho planet?rio por mistura mec?nica e mo?dos por 2 h, 100 h, 200 h e 300 h. Os comp?sitos em p? foram compactados numa matriz de 10 mm de di?metro a uma press?o de 200 Mpa e sinterizadas a 1400 0C/ 5 min no forno acoplado ao dilat?metro com atmosfera de arg?nio. Os comp?sitos foram submetidos a um processamento metalogr?fico de corte, embutimento, lixamento e polimento. A caracteriza??o dos comp?sitos consistiu em difra??o de raios-X, microscopia ?ptica, microscopia eletr?nica de varredura, dureza, propriedades magn?ticas e an?lise dos par?metros microestruturais pelo m?todo de Rietveld. Os resultados mostram que o tempo de moagem promove uma redu??o do tamanho de part?cula. Os comp?sitos com maior tempo de moagem sinterizam a menor temperatura. O tempo de moagem promove ainda a soldagem a frio das part?culas originando a forma??o de part?culas comp?sitas e transforma??es alotr?picas na fase cobalto. O difratograma de raios-X para os p?s comp?sitos mostra uma queda da intensidade dos picos de WC com o tempo de moagem. O difratograma de raios-X para os comp?sitos sinterizados mostra a presen?a de outras fases. As medidas magn?ticas detectaram um decr?scimo na magnetiza??o de satura??o e um crescimento no campo coercitivo com o aumento do tempo de moagem. Com o tempo de moagem foi verificado um decr?scimo do tamanho de gr?o. Para os p?s comp?sitos o aumento do campo coercitivo est? relacionado com a redu??o do tamanho de part?cula e a varia??o da magnetiza??o de satura??o est? relacionada com a varia??o do cobalto livre. O m?todo de Rietveld mostrou que a varia??o do tamanho m?dio do cristalito com o tempo de moagem das fases WC e Co-cfc foi menor nos comp?sitos sinterizados do que nos p?s comp?sitos. J? na fase Co-cfc esta varia??o foi maior nos p?s. A deforma??o m?dia do cristalito das fases WC, Co-hc e Co-cfc ? maior nos p?s comp?sitos do que nos comp?sitos sinterizados. Nos p?s comp?sitos os par?metros de rede para as fases WC, Co-hc e Co-cfc decrescem com o tempo de moagem. Este decr?scimo est? diretamente influenciado pela redu??o do tamanho das part?culas. Para os comp?sitos sinterizados os par?metros de rede para as fases WC, Co-hc e Co-cfc s?o praticamente constantes

The calcium ferrite (Ca2Fe2O5) has a perovskite-type structure with oxygen deficiency and is used as a chemical catalyst. With the advent of nanoscience and nanotechnology, methods of preparation, physical and chemical characterizations, and the technological applications of nanoparticles have attracted great scientific interest. Calcium nanostructured ferrites were produced via high-energy milling, with subsequent heat treatment. The milling products were characterized by X-ray diffraction, magnetization and M?ssbauer spectroscopy. Samples of the type Ca2Fe2O5 were obtained from the CaCO3 and Fe2O3 powder precursors, which were mixed stoichiometrically and milled for 10h and thermally treated at 700?C, 900?C and 1100?C. The M?ssbauer spectra of the treated samples were adjusted three subespectros: calcium ferrite (octahedral and tetrahedral sites) and a paramagnetic component, related to very small particles of calcium ferrite, which are in a superparamagnetic state. For samples beats in an atmosphere of methyl alcohol, there is a significant increase in area associated with the paramagnetic component. Hysteresis curves obtained are characteristic of a weak ferromagnetic-like material

No presente trabalho foram sintetizados comp?sitos, a partir da moagem de altaenergia dos precursores hidroxiapatita - HAp (Ca10(PO4)6(OH)2) e ferro met?lico (?-Fe),com o intuito de serem utilizados em hipertermia magn?tica no tratamento do c?ncer. Osprodutos da moagem foram caracterizados por difratometria de raios X (DRX),microscopia eletr?nica de varredura (MEV), espectroscopia de energia dispersiva (EDS),medidas de magnetiza??o em fun??o do campo aplicado e medidas de temperatura emfun??o do campo alternado. Os DRX das amostras batidas de HAp/Fe revelaram somente apresen?a dos precursores. O MEV mostrou aglomerados com formatos irregulares. Ascurvas de magnetiza??o obtidas apresentam casos t?picos de comportamentoferromagn?tico fraco. Para as amostras batidas e submetidas a tratamento t?rmico asseguintes fases foram identificadas: HAp (Ca10(PO4)6(OH)2) , hematita (Fe2O3) e ferrofosfato tric?lcio, FeTCP, Ca19Fe2 (PO4)14. Analisando os resultados de M x H, verificou-seuma redu??o na magnetiza??o de satura??o, tendo em vista que o Fe foi incorporado ?HAp. As curvas de histerese, obtidas a 300 K, s?o caracter?sticas de amostras que possuemmais de uma fase. Em 77 K, o comportamento da curva de histerese ? influenciado pelapresen?a da hematita que ? antiferromagn?tica. J? em T = 4,2K, ? observado umcomportamento ferromagn?tico fraco. Al?m disso, verifica-se o efeito de ?exchange bias?.Os resultados obtidos das medidas de temperatura em fun??o do campo alternado s?opromissores para aplica??es em hipertermia magn?tica e outras aplica??es biom?dicas.
In this work, composites were prepared using high energy mechanical milling from the precursors hydroxyapatite - HAp (Ca10(PO4)6(OH)2) and metallic iron ( -Fe ). The main goal here is to study composites in order to employ them in magnetic hyperthermia for cancer therapy. The produced samples were characterized by X-ray di raction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), magnetization curves as a function of applied eld (MxH), and nally measurements of magnetic hyperthermia. The XRD patterns of the milled samples HAp/Fe revealed only the presence of precursor materials. The SEM showed clusters with irregular shapes. The magnetization curves indicated typical cases of weak ferromagnetic behavior. For samples submitted to grinding and annealing, the identi ed phases were: HAp (Ca10(PO4)6(OH)2), hematite (Fe2O3) and Calcium Iron Phosphate (Ca9Fe(PO4)7). Analyzing the results of MxH, there was a reduction of the saturation magnetization, given that the Fe was incorporated into HAp. Hysteresis curves obtained at 300 K are characteristics of samples possessing over a phase. At 77 K, the behavior of the hysteresis curve is in uenced by the presence of hematite, which is antiferromagnetic. Already at T = 4.2 K, it is observed a weak ferromagnetic behavior. Furthermore, there is the e ect of exchange bias. Regarding the magnetic hyperthermia, the results of temperature measurements as a function of the alternating eld are promising for applications in magnetic hyperthermia and other biomedical applications.

To Schopenhauer, a genius is characterized by the surplus of the faculty of knowing, which allows these individuals to have immediate access to the Idea through the intuitive contemplation, while a pure being of the knowledge. However, this potentiality amplifies the genius? will, when the status of individual is retaken. According to the philosopher, the surplus of the faculty of knowing may take two guidances, which exclude themselves: the objective guidance, when one is freed from the bondage of the will, or the indirect guidance, occasion when the surplus is available to the individual guidance. As a consequence of the surplus, the genius either neglects suffering or suffers radically. This work intends to present the following hypothesis: the genius goes through existential drama that greatly surpasses the natural suffering inherent to other people. Thereunto Torquato Tasso, Goethe?s work, was utilized, since it has been mentioned by Schopenhauer
Para Schopenhauer, o que caracteriza o g?nio ? o excedente da faculdade de conhecer (genialidade) que lhe possibilita acesso imediato ? Ideia por meio da contempla??o intuitiva, enquanto puro sujeito do conhecimento. Todavia, esta mesma potencialidade amplifica a vontade do g?nio, quando este retoma a condi??o de indiv?duo. Segundo o fil?sofo, o excedente da faculdade de conhecer pode tomar duas orienta??es, excludentes entre si: a orienta??o objetiva, quando ele se torna livre da servid?o da vontade, ou a orienta??o subjetiva, ocasi?o em que o excedente se coloca a servi?o da vontade individual. Por conta dessas duas orienta??es do excedente, o g?nio ora se abst?m do sofrimento, ora sofre de maneira extremada. O presente trabalho pretende apresentar a hip?tese de que o g?nio vivencia um drama existencial, que ultrapassa sobremodo o sofrimento natural inerente aos outros homens. Para tanto, objetiva-se recorrer ? obra Torquato Tasso do Goethe, citada pelo pr?prio Schopenhauer.

The drug targeting has been the subject of extensive studies in order to develop site-specific treatments that minimize side effects and become more effective anticancer therapy. Despite considerable interest in this class, drugs like antibiotics also have limitations, and have been neglected. Using new pharmaceutical technologies, the use of magnetic vectors appear as promising candidate for drug delivery systems in several studies. Small magnetic particles bound to the drug of interest can be modulated according to the orientation of a magnet outside the body, locating and holding in a specific site. In this work, we propose the use of High Energy Milling (HEM) for synthesis of a magnetic vector with characteristics suitable for biomedical applications by intravenous administration, and for the formation of an oxacillin-carrier complex to obtain a system for treating infections caused by Staphylococcus aureus. The results of the variation of milling time showed that the size and structural properties of the formed material change with increasing milling time, and in 60 hours we found the sample closest to the ideal conditions of the material. The vector-drug system was studied in terms of structural stability and antimicrobial activity after the milling process, which revealed the integrity of the oxacillin molecule and its bactericidal action on cultures of Staphylococcus aureus ATCC
A vetoriza??o de f?rmaco tem sido alvo de exaustivos trabalhos no intuito de desenvolver tratamentos s?tio-espec?ficos que minimizem efeitos adversos e torne mais efetiva a terapia antineopl?sica. Apesar do grande interesse nessa classe, f?rmacos como os antibi?ticos tamb?m apresentam limita??es, e t?m sido negligenciados. Utilizando novas tecnologias farmac?uticas, o emprego de vetores magn?ticos aparece como candidato promissor para sistemas de entrega de f?rmaco em in?meros estudos. As pequenas part?culas magn?ticas ligadas ao f?rmaco de interesse podem ser moduladas de acordo com a orienta??o de um ?m? externo ao corpo, localizado e retendo o ativo no local de interesse. Nesse trabalho n?s propomos a utiliza??o de Moagem de Alta Energia (MAE) para s?ntese do vetor magn?tico com caracter?sticas apropriadas para aplica??es biom?dicas por via de administra??o intravenosa, e para complexa??o do carreador ? Oxacilina para obten??o de um sistema para tratamento de infec??es por Staphylococcus aures. Os resultados da varia??o do tempo de moagem demonstraram que as propriedades estruturais e de tamanho do material formado se alteram com o aumento do tempo de moagem, e dentre os per?odos estudados, 60 horas foi escolhido como o mais pr?ximo das propriedades ideais do material. A complexa??o vetor-f?rmaco foi estudada em termos de estabilidade estrutural e de atividade antimicrobiana ap?s o processo de moagem, que revelaram a integridade da mol?cula de Oxacilina e de sua a??o bactericida sobre culturas de Staphylococcus aures ATCC

As ferritas de cobalto-mangan?s (Co1?xMnxFe2O4 e Co1,2Fe1,8?xMnxO4) possuem uma estrutura do tipo espin?lio mista, e t?m sido consideradas como um das candidatas competitivas para grande variedade de aplica??es em dispositivos, desde a gera??o e detec??o de ultra-som, sensores, transformadores, bem como na ind?stria m?dica. Ferritas de cobaltomangan?s nanoestruturadas foram produzidas via moagem de alta energia, com subsequente tratamento t?rmico, e foram caracterizados por difra??o de raios X, fluoresc?ncia de raios X, microscopia eletr?nica de varredura e magnetiza??o. Amostras do tipo Co1?xMnxFe2O4 e Co1,2Fe1,8?xMnxO4 foram obtidas a partir dos p?s precursores Fe3O4, Co3O4 e Mn3O4, os quais foram estequiometricamente misturados e mo?dos por 10h e tratados termicamente ? 900?C por 2h. A difratometria confirma a forma??o das fases nanocristalinas puras para s?rie Co1,2Fe1,8?xMnxO4 com umdi?metro m?dio de cerca de 94nm. Verificou-se que o par?metro de rede aumenta com a substitui??o do Fe3? pelo Mn3?. A fluoresc?ncia de raios X revelou que as por??es de metais nas amostras estavam pr?xima das composi??es estequiom?tricas nominais. As caracter?sticas microestruturais observadas nas micrografias demonstraram que as part?culas formadas apresentam morfologia e granulometria bastante distintas. As medidas de histerese magn?ticas realizadas em baixa temperatura, mostraram que a magnetiza??o de satura??o e reman?ncia aumentaram com a concentra??o de mangan?s, enquanto que o campo coercivo diminuiu. A constante de anisotropia (Ke f ), foi calculada a partir dos ajustes dos dados pela lei de aproxima??o de satura??o. Verificou-se que a anisotropia diminui substancialmente com a substitui??o do ferro pelomangan?s.
The cobalt-manganese ferrites (Co1?xMnxFe2O4 and Co1,2Fe1,8?xMnxO4) has a mixed structure of spinel type and it has been regarded as one of candidates for petitive wide variety of applications in devices from ultrasonic generation and detection, sensors, transformers, as well as in medical industry. Ferrites cobalt-manganese nanostructured were produced via mechanical alloying with subsequent heat treatment and were characterized by X-ray diffraction, X-ray fluorescence, scanning electron microscopy and magnetization. Samples of Co1?xMnxFe2O4 and Co1,2Fe1,8?xMnxO4 were obtained from the precursor powders Fe3O4, Co3O4 and Mn3O4 which were stoichiometrically mixed and ground by 10h and heat treated at 900?C for 2h. The diffraction confirmed the formation of the pure nanocrystalline phases to series Co1,2Fe1,8?xMnxO4 with an average diameter of about 94nm. It was found that the lattice parameter increases with the substitution of Fe3? by Mn3?. The x-ray fluorescence revealed that the portions of metals in samples were close to the nominal stoichiometric compositions. The microstructural features observed in micrographs showed that the particles formed show very different morphology and particle size. The magnetic hysteresis measurements performed at low temperature showed that the saturation magnetization and remanence increased as the concentration of manganese, while the coercive field decreased. The anisotropy constant (Ke f ), was estimated from the data adjustments the law of approaching saturation. It was found that the anisotropy decreases substantially with the substitution of Fe by Mn.

Os dois artigos desta tese, os capítulos 2 e 3, referem-se a testes de hipótese mas têm focos diferentes. O capítulo 2, intitulado "Improvements for external validity tests in fuzzy regression discontinuity designs," apresenta condições --- hipóteses de continuidade, monotonicidade estrita e convergência pontual --- sob as quais testes de qualidade de ajuste para duas amostras podem ser usados para testes de validade externa em modelos de tratamento-controle que sofrem de "compliance" imperfeito. Modelos com "compliance" imperfeito permitem a estimação de efeitos de tratamento apenas para a subpopulação de "compliers", sendo que tais estimativas não são necessariamente válidas para outras subpopulações ("always-takers" e "never-takers"). Sob as condições do capítulo 2, o uso do teste de qualidade de ajuste no lugar do teste de diferença de médias representa um avanço para testes de validade externa, uma vez que mais hipóteses alternativas são detectáveis pelo primeiro teste. Sugerimos combinar duas estatísticas de teste de qualidade de ajuste (uma para tratados e outra para não tratados) na forma de um teste múltiplo ao invés de um teste conjunto. O capítulo 3, intitulado "Higher-order UMP tests", sugere uma estratégia para se escolher, dentro de um conjunto de estatísticas de teste disponíveis, aquela que fornece o teste mais poderoso quando as funções de poder dos testes em questão não podem ser diferenciadas através de métodos assintóticos usuais, como análise de poder local ("local power analysis"). Propomos o uso de aproximações assintóticas de ordem mais alta, como expansões de Edgeworth, para se aproximar as densidades amostrais das estatísticas disponíveis e, com isso, verificar-se quais delas possuem a propriedade da razão monotônica de verossimilhança. Tal propriedade implica, pelo Teorema de Karlin-Rubin, que o teste é uniformemente mais poderoso (UMP) --- ao menos até certa ordem de aproximação --- se a estatística for suficiente para o parâmetro relevante. Para o caso em que as estatísticas sendo comparadas não são suficientes, argumentamos que frequentemente elas podem se tornar suficientes para uma família paramétrica de interesse após reparametrizações apropriadas. Para fins de ilustração, nós aplicamos o método proposto para determinar o valor ótimo, em termos de poder, do parâmetro de suavização do estimador de densidade por kernel em bases de dados simuladas e concluímos que a ordem de aproximação usada nesta aplicação (segunda ordem) não é alta o suficiente para permitir a diferenciação das funções de poder associadas aos diferentes valores do parâmetro de suavização.
The two papers in this work, chapters 2 and 3, regard hypothesis testing but address different issues. Chapter 2, entitled "Improvements for external validity tests in fuzzy regression discontinuity designs", shows conditions --- assumptions of continuity, strict monotonicity and pointwise convergence --- under which two-sample goodness-of-fit (GOF) tests can be used to test for external validity in treatment-control models that suffer from imperfect compliance of units with respect to the assigned treatment. Imperfect compliance allows researchers to estimate only treatment effects for the subpopulation of compliers, and the validity of these estimates for other subpopulations (always-takers and never-takers) remains an open problem. Under the conditions in Chapter 2, the use of GOF tests in place of mean difference tests represents an improvement over other external validity tests in the literature, since more alternative hypotheses are detectable by the test statistic. We suggested to combine two GOF test statistics (one for the treated and one for the untreated) in a multiple test instead of a joint test. Chapter 3, entitled "Higher-order UMP tests", suggests a strategy to choose among candidate test statistics, according to a power criterion, when their power performances are not distinguishable by usual methods of asymptotic comparison like local power analysis. We propose the use of higher-order asymptotic expansions, like Edgeworth expansions, to approximate the sample densities of the candidate test statistics and verify which of them has the monotone likelihood ratio property. This property implies, by the Karlin-Rubin Theorem, that the test is uniformly most powerful (UMP) --- at least to an order of approximation --- if the statistic is sufficient for the relevant parameter. When the statistics under study are not sufficient, we argue that they can often be made sufficient for a desired parametric family after appropriate reparameterization. We applied the method to search for the power-optimal bandwidth for the kernel density estimator in simulated data sets, and concluded that the order of approximation that we used (second order) is still too low to allow us to distinguish among bandwidths.

Sugar cane is one of the crops with the highest level of water consumption, with a high evapotranspiration demand throughout most of its cycle. Knowledge of the sugar cane water demand, the time that irrigation should be applied, and how to irrigate the crop are becoming increasingly important for the sustainable development of irrigated sugar cane cultivation, especially in areas of low water availability, as it is the case in northea stern Brazil. The experiment was carried out at the Curu Experimental Field (property of the Embrapa Tropical Agroindustry), located in the Curu-Paraipaba Irrig ation Project, city of Paraipaba-CE (3 ° 29 '20''S, 39 ° 9' 45''W and elevation 30m), in order to determine the evapotrans piration and crop coefficients (Kc) of sugarcane (Saccharum L. officinarium), subsurface drip-irrigated. It was used the SP 6949 sugar cane variety, planted in a spacing of 1.8 m between double rows and 0.4 m between rows within the double row. As to t he irrigation, we used one lateral water line for each double row, buried at a depth of 0.15 m, w ith self-compensating drip emitters, with a flow rate of 1 L h-1, spaced 0.5 m on the water line. The crop was irrigated daily and there were three fertigations per week. The irrigation de pth was periodically adjusted, keeping the soil water potential between -8 kPa to -20 kPa. The crop evapotranspiration (ETc) was determined using a wei ghing lysimeter with a surface area of 2.25 m 2. The reference evapotranspiration (ETo) was estimated by the FAO Penman-Monteith method. The durations of the phenological stages of cane sugar were estimated through analysis of soil cover, with the use of digital images. Durations of 31, 49, 237 and 118 days were observed, respectively for initial, crop development, mid-season and late season stages. The yields achieved within and outside the lysimeter were respectively 144.4 and 108.8 t ha -1 . The total ETc observed during the cycle of the sugar cane was 1074.1 m m, with maximum values of 6.6 mm d-1 during the mid-season stage. Observed Kc values for initial, mid-season and late season stages were respectively 0.23, 1 .03 and 0.50. In the crop development stage, the relationship between Kc and the (crop) soil cover was represented with good accuracy by a negative quadratic model.
A cana-de-açúcar é uma das culturas com maior consumo de água, apresentando uma alta demanda evapotranspirativa ao longo da maior parte do seu ciclo. O conhecimento das necessidades hídricas da cana-de-açúcar, do momento de aplicação da água requerida pela mesma e a forma de aplicação torna-se cada vez mais importante para o desenvolvimento sustentável da sua produção irrigada, principalmente em regiões de pouca disponibilidade hídrica, como é o caso da região Nordeste do Brasil. O experimento foi conduzido no Campo Experimental do Curu, pertencente à Embrapa Agroindústria Tropical localizado no Perímetro Irrigado Curu-Paraipaba, município de Paraipaba-CE (3° 29’ 20’’ S, 39° 9’ 45’’ W e altitude de 30 m), com o objetivo de determinar a evapotranspiração e os coeficientes de cultivo (Kc) da cana-de-açúcar (Saccharum officinarium L.), irrigada por gotejamento subsuperficial. Utilizou-se a variedade de cana SP 6949, plantada no espaçamento de 1,8 m entre fileiras duplas e 0,4 m entre linhas dentro da fileira dupla. Na irrigação utilizou-se uma linha lateral para cada fileira dupla, enterrada na profundidade de 0,15 m, com gotejadores autocompensantes, com vazão de 1 L h-1, espaçados de 0,5 m na linha. A cultura foi irrigada com freqüência diária e foram realizadas três fertirrigações por semana. A lâmina de irrigação foi ajustada periodicamente, mantendo-se o potencial de água no solo entre -8 kPa e -20 kPa. A evapotranspiração da cultura (ETc) foi determinada utilizando-se um lisímetro de pesagem com área superficial de 2,25 m2. A evapotranspiração de referência (ETo) foi estimada pelo método FAO Penman-Monteith. As durações das fases fenológicas da cana-de-açúcar foram estimadas por meio da análise da cobertura do solo pela cultura, determinada com o uso de imagens digitais. Foram observadas durações de 31, 49, 237 e 118 dias, para as fases inicial, de desenvolvimento, intermediária e final, respectivamente. A produtividade alcançada dentro e fora do lisímetro foi de 144,4 e 108,8 t ha-1, respectivamente. A ETc total observada durante o ciclo da cana-de-açúcar foi de 1.074,1 mm, com valores máximos da ordem de 6,6 mm d-1 durante a fase intermediária. Foram observados valores de Kc iguais a 0,23, 1,03 e 0,50, para as fases inicial, intermediária e final, respectivamente. Na fase de desenvolvimento vegetativo a relação entre o Kc e a cobertura do solo pela cultura foi representada com bastante exatidão por um modelo quadrático negativo.

Bolz, Sophia. „Erstellung von Normkurven eines neu entwickelten Sprachaudiometrietests mit Einsilbern, genannt „Dynamischer Zahlentest“, zu drei verschiedenen Sprechern – Mann, Frau und Kind – und jeweils drei verschiedenen Sprachmodi – normal, gerufen und geflüstert – an normalhörenden Erwachsenen im Alter von 19-27 Jahren ohne Störgeräusch“. Doctoral thesis, 2010. https://nbn-resolving.org/urn:nbn:de:bvb:20-opus-56203.
Der volle Inhalt der QuelleAnnotation:
Ziel dieser Arbeit war es, mit Hilfe 35 normalhörender Probanden im Alter von 19-27 Jahren Schwellenkurven (Speech reception threshold) zu einem neu aufgenommenen dynamischen Einsilbertest mit den Zahlen eins bis zwölf (enthält den Zweisilber sieben) und den Farben braun, blau, gelb, grün, rot, schwarz und weiß zu erstellen. Die Versuche sollten zunächst orientierende Ergebnisse der Sprachverständlichkeiten zu den verschiedenen Sprachmodi ohne Störlärm liefern. Das Besondere an diesem sprachaudiometrischen Test waren neun verschiedene Sprachmodi, kombiniert aus den Stimmen drei verschiedener, unterschiedlich gut trainierter Sprecher – Mann, Frau und Kind – mit den oben genannten Wörtern in geflüsterter, normaler und gebrüllter Sprache. Die für jeden Modus charakteristischen Sprachverständlichkeits-schwellen sind eine 50%ige Sprachverständlichkeit in den Modi Mann flüsternd bei einem Schalldruckpegel von 32,0 dB, Frau flüsternd bei 31,7 dB, Kind flüsternd bei 38,3 dB; Mann normal bei 26,7 dB; Frau normal bei 23,4 dB, Kind normal bei 25,7 dB; Mann laut bei 17,9 dB, Frau laut bei 16,6 dB und Kind laut bei 13,2 dB. Hieran kann deutlich gezeigt werden, dass stimmlose Flüstersprache schwieriger verstanden wird und höhere Schalldruckpegel zum Erreichen der Schwelle bzw. der vollständigen Sprachverständlichkeit benötigt, als leiser gedrehte normal betonte Sprache, wie es bei üblichen Sprachtests der Fall ist. Die verschiedenen Steigungen der sigmoidalen Sprachverständlich-keitskurven von Mann flüsternd 3,4%/dB, Frau flüsternd 4,3%/dB, Kind flüsternd 2,6%/dB; Mann normal 5,9%/dB; Frau normal 5,1%/dB, Kind normal 2,9%/dB; Mann laut 5,0%/dB, Frau laut 2,2%/dB und Kind laut 2,7%/dB, zusammen mit weiteren graphischen Analysen der Verständlichkeits-Pegel-Diagramme, lassen die Sprecherqualitäten der jeweiligen Sprachmodi beurteilen. Die Variabilitäten sowohl interindividuell als auch sprachmodusbezogen zeigen, dass erst verschiedene Sprecher sowie unterschiedliche Betonung der Testsprache geeignet sein könnten, um dem gesamten Sprachspektrum, dem ein Mensch in seinem sozialen Umfeld ausgesetzt ist, bei der Hörgeräte-anpassung näher zu kommen. Dieser neue Sprachtest vereint in Geschlecht und Alter verschiedene Sprecher mit geflüsterter, normaler und gerufener Sprache und wird durch sein knappes Testwörtervolumen klinisch anwendbar. Durch das größere getestete Sprachspektrum könnte bereits eine beginnende, subjektiv noch nicht wahrgenommene Schwerhörigkeit aufgedeckt werden. Die Untersuchungen des Sprachmaterials zeigen, dass ein Proband je nach Trainingslevel des Sprechers unterschiedlich gute Sprachverständlichkeiten erreicht. Ein Testergebnis ist somit nicht unerheblich von der Qualität des Sprechers abhängig. Weiterhin werden auch die Sprachverständlichkeiten auf jedes einzelne Wort hin betrachtet. Das Testmaterial erscheint außer den Wörtern „acht“ und „braun“ in seiner Verständlichkeit homogen. So ist es nicht verwunderlich, dass sich Hörgeräteträger in besonderen Alltagssituationen, zum Beispiel während eines Gesprächs mit dem Enkel, von ihrer Hörhilfe im Stich gelassen fühlen. Dies bestätigen Zahlen aus Studien über die allgemein niedrige Hörgeräteakzeptanz. Die für einen Hörverlust typischen Handicaps und die damit verbundenen Anforderungen an ein Hörgerät verlangen sensiblere Methoden zur Hörgeräteanpassung mit dem Ziel, die Hörgeräteakzeptanz zu verbessern. Die Untersuchung des Testmaterials an Menschen mit Hörverlust sowie in einer alltagsnahen Testsituation mit Störlärm soll in weiteren Studien abgeklärt werdenThe aim was to generate the speech reception thresholds of a new developed speech audiometry test on 35 normal hearing persons in the age of 19-27. The test contains the numbers one to twelve and the colours brown, blue, yellow, green, red, black and white. First the experiment should result in normal curves without background noise. The speciality of this speech test were nine different mode in speech, combined of three different voices of speakers with different training level - man, woman and child - with whispered, normal and shouted intonation. The characteristic speech reception thresholds were with "man whispered" at 32,0 dB, "woman whispered" at 31,7 dB, "child whispered" at 38,3 dB, "man normal" at 26,7 dB, "woman normal" at 23,4 dB, "child normal" at 25,7 dB, "man shouted" at 17,9 dB, "woman shouted" at 16,6 dB and "child shouted" at 13,2 dB. The gradients and the graphic analysis of the curves gave information about the speakers quality. The variabilities show, that different speakers and different mode of speech could be able to simulate the whole acoustic spectrum in the process of fitting a hearing aid. This speech audiometry test could be a method to make this process more sensitive in order to advance the acceptance of using a hearing aid.

This thesis is divided into two main parts. The First cultural-historical part is dedicated to introduction of cultural-historical context between Bohemian kingdom and Silesia. Historical development of Silesia and its joining into the union of Lands of Bohemian crown is also shortly discussed. The second art-historical chapter in first part brings the resume of literature dedicated to phenomenon of beautiful style. The second part brings resume of literature dedicated particularly to the Silesian centre of beautiful style. And the last part of this chapter consists of a catalogue of chosen works of beautiful style from Wroclaw. Those are Pietà of St. Elisabeth in Wroclaw, Pietà of Virgin Mary on Sand church in Wroclaw, Man of sorrows from Goldsmith's altar, Pietà from St. Stanislaw and Wenzel church in Sweidnitz, Pietà from St. Matthew church. For each of these works a detailed formal analysis is made and existing research outputs are summarized. As a conclusion of researches mentioned above an attempt is made to improve accuracy of dating and to answer some questions related to those works of art.

Tese de doutoramento em Ciências Farmacêuticas, na especialidade de Farmacognosia e Fitoquímica, apresentada à Faculdade de Farmácia da Universidade de CoimbraCymbopogon citratus (DC). Stapf (Poaceae), commonly known as lemongrass, is a tropical perennial shrub originated from the Southeast Asia. This plant is reported to possess antifungal, insecticidal, anti-diabetic, anti-septic, anti-mutagenic, anti-carcinogenic activities as well as anti-inflammatory. In fact, aqueous extracts of dried leaves are used all over the year in folk medicine for the treatment of peptic ulcers and inflammatory conditions. Recently, some phenolic compounds, such as luteolin and apigenin glycosides and condensed tannins, were identified and related to both antioxidant and anti-inflammatory properties. The purposes of this work were to i) validate an analytical method for quantification of phenolic compounds of C. citratus; ii) study the influence of harvest time and plant quality on the phenolic composition and antioxidant activity; iii) characterize the tannins; iv) validate the traditional uses of lemongrass infusion as anti-inflammatory in vivo; v) obtain a topical formulation to evaluate the phenolic compounds permeation and their anti-inflammatory activity; vi) trace the pharmacokinetic profile of the main phenolic compounds in rats. Three different extracts: infusion (CcI), 50% aqueous ethanol (CcM50%) and ethanol (CcM100%) extracts were prepared and a simple and efficient RP-HPLC-PDA method was successfully validated for simultaneous identification and quantification of phenolic acids and flavonoids. Infusions were also obtained from different harvest dates (April, June, July, August and September) and quality grades (High, Medium and Low). It was verified that the content on polyphenols and the antioxidant capacity of CcI is strongly related with the quality of the plant. The total phenols assay showed a substantial loss from August to September. It was possible to find out the best month to harvest the plant to get the most of each phenolic group: April and June for hydroxycinnamic acids; June and September for flavonoids; June, July and August for tannins. Regardless the group of phenolic compound addressed, its content was always inversely proportional to the degree of leaves ageing. For all tested oxidant species, the high-quality samples exhibited the best antioxidant results. CcI was fractionated by column chromatography and polyphenol-rich fractions, namely phenolic acids (CcPA), flavonoids (CcF) and tannins (CcT) were obtained. CcT was characterized by HPLC-PDA-ESI/MSn, revealing the presence of proanthocyanidin hetero-dimers, along with some common procyanidin dimers. These hetero-dimeric flavan structures have been described for the first time in lemongrass and consist of apigeniflavan or luteoliflavan units linked to a flavanone, either naringenin or eriodictyol, and may occur as aglycone or glycosylated forms. For the in vivo assays, CcI, CcF and CcT were tested. CcI administered before and after ethanol stimulus, significantly reduced the incidence and severity of gastric lesions and, consequently, the ulcer index, corroborating the traditional medicinal use of this plant to ameliorate gastritis and/or peptic ulcers symptoms. On the other hand, CcI, CcF and CcT were orally administered to rats, in order to evaluate the anti-inflammatory effect at the carrageenan-induced paw edema assay. The observed effect by CcI (68.24 mg/kg), 82.30% of edema inhibition, was very similar to that obtained by the reference NSAID used (diclofenac, 10 mg/kg), 84.00%. On the other hand, flavonoid (7.42 mg/kg) and the tannin-rich (5.96 mg/kg) fractions significantly contributed for the anti-inflammatory activity on the edema volume (59 and 61%, respectively). The topical anti-inflammatory activity of CcI was also addressed. The results suggest that flavonoids, mainly, luteolin 7-O-neohesperidoside, cassiaoccidentalin B, carlinoside and cynaroside, may contribute to the topical anti-inflammatory effect. CcF (0.6%), CcT (0.3%) and CcF+CcT (0.66%+0.34%) topical formulations were also tested, and the results obtained suggest that tannins and flavonoids also possess a significant activity and that a synergistic mechanism of action may occur. In fact, edema inhibitions of 43%, 47% and 59% were respectively verified, being CcF+CcT effect very close to that of 1% diclofenac (65.9%). Pharmacokinetic analysis was performed in plasma, liver and kidney and showed that the compounds present in CcI are not detected in vivo after a single-dose oral administration. In contrary, the metabolites, luteolin 7-O-glucuronide and luteolin 3’-O-sulfate, present at the highest bioavailability, are probably the main responsible for the anti-inflammatory activity previously reported. In conclusion, this work has developed a method to quantify the phenolic compounds contained in C. citratus; pointed the importance of harvesting and storing the plant material, in order to take the maximum advantages from the phenolic compounds use; and demonstrated, in safe doses, its anti-inflammatory activity, using an in vivo approach, which supports the traditional use of lemongrass infusion. Furthermore, C. citratus leaves flavonoids and tannins were highlighted as bioactive compounds, encouraging the development of new anti-inflammatory drugs or nutraceuticals.
