This thesis deals with french V-N compounds (casse-noisettes) and their occurences in frWac corpus. The first aim of this work is to describe composition and french compounds, particularly the V-N compounds. The second aim is to verify their occurences in frWac corpus and to characterize their semantic and morphosyntactic properties. This work is divided in two parts: the theoretical and the practical one. The first one deals with the process of composition and compounds in general with special attention to characteristics of VN compounds. In the second part, the corpus analysis will be proceeded, the quantitative and the qualitative ones. The subject of research are the VN compounds, we will focus especially on their morphological, syntactic and semantic properties.

Estes causam obstrução total ou parcial da secção transversal das tubulações e um acréscimo considerável na viscosidade do óleo, gerando por várias vezes longas interrupções. Um dos métodos usados para resolver o problema durante a extração é a injeção de fluidos quentes, de surfactantes e solventes, em geral tóxicos e facilmente inflamáveis. Por estes motivos, neste trabalho, investigou-se a influência da adição de diluentes e de surfactantes sobre o comportamento reológico, estabilidade e morfologia de emulsões de um petróleo contendo água. Verificamos a influência da temperatura, concentração e polaridade do meio e do surfactante. Foram sintetizados dois surfactantes não iônicos, a base de poli (dimetilsiloxano), um polar, PDMS-ester (SP) e o outro apolar, PDMS-hidrocarboneto (SA). Eles foram analisados por FTIR, solubilidade, DSC, TGA, CMC e propriedades interfaciais. O petróleo utilizado e o seu respectivo depósito parafínico foram caracterizados quanto à distribuição de átomos de carbono das parafinas, FTIR, ponto de fluidez, morfologia dos cristais, comportamento reológico e determinação da TIAC. Foram preparadas emulsões contendo entre 40 e 44% de petróleo com e sem surfactantes, a fase dispersa foi água-diluente e água-mistura de diluentes. Os diluentes foram heptano, etilenoglicol (E), silicone (S) e glicerol (G). Os modelos de Bingham, Herschell-Bulkley e Casson foram ajustados à curva da dependência da tensão com a taxa de cisalhamento (a várias temperaturas, concentrações, tipo de diluente e de surfactante). A influência de cada componente da emulsão sobre os parâmetros das equações foi avaliada através de matriz de correlação. Foi observado que todas as emulsões, com e sem surfactantes apresentaram comportamento pseudoplástico. As suas viscosidades foram de 7 a 100 vezes menores do que a do petróleo. Elas dependeram do tipo e concentração dos diluentes e surfactantes. Não se observou correlação entre viscosidade e tamanho de gotas da fase dispersa. A dependência da viscosidade com a temperatura evidenciou que as emulsões solubilizaram as parafinas. A 30 0C, as emulsões petróleo/heptano/ diluente/água com etilenoglicol seguiram o modêlo de Herschell-Bulkley e aquelas com glicerol seguiram o modêlo de Casson. A 40, 50 e 60 0C, o modêlo de Casson descreveu o comportamento das emulsões com etilenoglicol e com glicerol. Todas as emulsões com surfactante seguiram o modêlo de Herschell-Bulkley em todas as concentrações e temperaturas investigadas As diferenças de comportamento reológico entre as emulsões de etilenoglicol/surfactante apolar e glicerol/surfactante polar foram atribuídas às diferenças de estrutura química e molecular dos diluentes e surfatantes. / Salvador

No domínio da morfologia derivacional, é difícil encontrar padrões de formação de palavras que possam se aplicar a todas as bases que se encaixam em seus contextos de aplicação. Isso equivale a dizer que a produtividade de padrões derivacionais costuma ser limitada. Entre as causas dessa limitação, vemos que formações potenciais são frequentemente bloqueadas por itens lexicais já existentes; em outros casos, elas são suplantadas por expressões formadas por padrões derivacionais concorrentes. Este trabalho dedica-se a explorar tais situações de competição. Iniciamos pelo exame da ideia de produtividade e de como entender as diferenças quantitativas entre padrões rivais quanto a este aspecto. Fazemos, em seguida, uma discussão mais detida da competição morfológica e da noção central de bloqueio, contrapondo às teorias gramaticais de base lexical uma abordagem pragmática deste fenômeno. Por fim, apresentamos o modelo desenvolvido em Albright e Hayes (1999) e em trabalhos posteriores, que explora a ideia de que o grau de confiabilidade do emprego de padrões morfológicos em diferentes contextos fonológicos é um fator determinante da produtividade desses padrões, bem como da competição entre eles. Testamos este modelo utilizando dados dos sufixos -ção e -mento, que se encontram em competição há bastante tempo no português. Estes dados provêm do Dicionário Houaiss 3.0 e de um levantamento de textos de jornais e blogs, coletados com o auxílio de programas computacionais desenvolvivdos para este trabalho. Nossos resultados sugerem que a manutenção da produtividade de -mento ao longo da história, mesmo após -ção ter se tornado o padrão dominante de nominalização, foi escorada pela existência de contextos fonológicos em que -mento atinge um alto grau de confiabilidade. Dada a produtividade da primeira conjugação, foram particularmente importantes os contextos de aplicação de -mento encontrados entre palavras desta classe verbal. Com base nestas generalizações, mostramos como um modelo estatístico é capaz de prever, na maior parte dos casos, a escolha entre estes dois afixos diante de uma nova base verbal. / In the field of derivational morphology, it is hard to find word formation patterns that may be applied to every base satisfying its context of application. This means that the productivity of derivational patterns is often limited. Among the causes of this limitation, we find that potential words are blocked by existing lexical items in many cases; in other cases, they are preempted by expressions formed by rival derivational patterns. This work devotes itself to exploring these instances of competition. We start by exploring the concept of productivity and by investigating how to understand quantitative differences between rival patterns in this respect. We then proceeed to a more detailed discussion of morphological competition and the fundamental notion of blocking, comparing a pragmatic approach to this phenomenon with lexicalist grammatical theories. Finally, we present the model of Albright e Hayes (1999) and later works, which explores the idea that the reliability of morphological patterns in different phonological contexts is a key determinant of the productivity of these patterns and the competition between them. We test this model on data formed by the suffixes -ção and -mento, which have been in competition for a long time in Portuguese. These data come from Dicionário Houaiss 3.0 and from a corpus created from newspapers and blogs with the help of software developed for this research. Our results suggest that the continued productivity of -mento throughout history, even after -ção had become the dominant nominalization pattern in the language, was supported by the existence of phonological contexts in which -mento reaches a high degree of reliability. Given the productivity of the first conjugation, contexts of application of -mento in words of this verbal class have shown to be especially important. We show that a statistical model equipped with these generalizations is able to predict the choice between these affixes in most cases.

Arundinaria gigantea (Walt.) Muhl. (giant cane) is a native North American bamboo. The mass assemblages of giant cane stems (culms) can form monotypic stands called "canebrakes" with historic distribution encompassing floodplains of the southeastern United States. Canebrake ecosystems have served as an important habitat for a variety of mammalian, avian, and reptilian species due in part by the protective nature the dense culms provide. Also, giant cane also can serve as an effective riparian zone buffer for the protection of water quality. Land conversion and altered disturbance regimes have reduced cane to 2% of historical accounts. Consistently, there is great interest in restoring canebrake ecosystems. However, canebrake restoration efforts face difficulties such as infrequent seeding and low viability, limited availability of seedlings or rhizome planting stock, and inefficient establishment and management techniques. To address these problems, two studies were designed to further develop giant cane propagation thereby aiding management efforts intended in restoring canebrake ecosystems. Study 1 (greenhouse) objective was to compare the survivability and growth responses of bare rhizomes and rhizomes with attached and trimmed culms with different planting orientation. Study design was a randomized complete block with approximately 20 rhizomes of each propagule type (bare rhizomes, rhizomes with culms trimmed to 3cm and rhizomes with culms trimmed to 20cm) planted in two orientations (buried flat or angled and partially exposed) in each of 4 benches (N=239). Propagule type and planting orientation were determined randomly. After six months, propagule survival was 86% and was independent of orientation (chi square 1df = 1.56, p=0.212) and propagule type (chi square 2df =3.88, p=3.88). There was an interaction between planting orientation and propagule type for the number of new rhizomes and culms, above ground biomass, but not for newly formed rhizome diameter or cumulative culm and rhizome length. Rhizome propagules with attached trimmed culms produced, on average, one more rhizome and were 71 cm longer than newly formed rhizomes from the bare rhizome propagules. Planting orientation had no effect on any measured character of long culmed propagules, burying the short-culmed or bare rhizomes tended to reduce growth responses. However, among exposed propagules, growth responses tended to be similar. Study 2 (field-scale) objective was to determine if genotype (3 collection sources) and collection season/ planting season (C/P) (fall/fall, fall/spring, spring/spring) affect survival and growth of giant cane. Study design was a randomized complete block design with between 12 and 20 bare rhizomes per each of 3 collection sources (subplots) planted in each of 3 rows (collection season/ planting season main plots) blocked 6 times across 2 sites (N=2086). Location of collection sources within subplots and C/P within plots were randomly chosen. Rhizomes were planted in rows using a tree planter. Mean survival of cane plants after one growing season was similar at each site with a mean of 11.1%. Survival was dependent on collection source and C/P seasons. Survival ranged from a high of 38.3% for the spring/spring planted Upper Cache River source to 0.4% for two of the other 9 treatment combinations. Collecting and planting rhizomes in the spring for two of the three collection sources produced the highest percent survival compared to stock collected in the fall then planted or stored until spring. These results suggest the importance of collection source, collection season, planting season, propagule morphology and orientation on the survival and new growth of giant cane in southern Illinois.

xvi, 169 p. ： ill. (some col.) / This dissertation describes the postcranial functional morphology of Theropithecus brumpti , a fossil cercopithecoid primate from the Plio-Pleistocene of East Africa. Theropithecus is often used as an analogue for human evolution, but much of our understanding of its paleobiology is based on the grassland adapted Theropithecus oswaldi , masking potential morphological and ecological breadth within the genus and limiting its use as an ecological comparator. To better understand the evolutionary history and ecological breadth of the genus, an analysis of the woodland associated T. brumpti is presented. All available T. brumpti postcranial material is included, along with comparative data on T. oswaldi and a large extant sample. Skeletal elements were metrically described using 125 postcranial measurements believed to have functional relevance. Measurements were transformed into 46 ratios to reflect shape and the functional lengths over which muscles act and to reduce the effects of differences in scale among individuals and species. Contrary to previous findings, there is no evidence T. brumpti was arboreal; rather it is clearly a terrestrial papionin. While T. brumpti retains a degree of flexibility (at the shoulder, elbow, hip, knee and ankle), this is not exceptional when compared to other members of the genus, notablyT. oswaldi . Not only are traits similar in both species, but there is a wide range of variation and overlap in both. Features historically used to reconstructT. brumpti as more arboreal are interpreted here as part of a suite of traits that characterize early Theropithecus . This suite of traits may instead be adaptations to manual terrestrial foraging, in particular adaptations related to forest floor locomotion and gleaning, which may be primitive for Theropithecus and possibly for papionins. This interpretation of the paleobiology of T. burmpti compared to that of T. oswaldi offers a parallel with hominins. New fossil evidence suggests use of terrestrial substrates in more woodland habitats for late Miocene to early Pliocene hominins, in contrast to more open habitats associated with later hominins. Therefore, this dissertation develops a framework for understanding the woodland to grassland transition among large bodied primates including hominins. / Committee in charge: Stephen Frost， Chairperson； Frances White， Member； John Lukacs， Member； Samantha Hopkins， Outside Member

This thesis describes the morphology and lexicon of the dialect of Romany spoken in Kotel, Bulgaria. The introduction shows the position of the dialect within Bulgarian Romany and gives brief details of its speakers (pp 12-15). A phonological transcription is used for the morphology and lexicon. This reveals the relationship between Kotel and other dialects, a relationship normally concealed by its phonetic system. The paradigmatic affixes added to nominals are listed with their variants and specimen paradigms are given (pp 16-31) . Verbs are similarly treated, with special notes on medio-passives and impersonal verbs (pp 32-42). The affixes used in building compound-words are listed with their variants and numerous examples (pp 43-59) o A brief note is included on some non-productive methods of word-formation (p. 60). The changes undergone by loan-words from Turkish and Bulgarian are summarized, together with the paradigmatic affixes used with loans from these languages and Greek (pp 61-66). Two texts are given in phonological transcription with a translation and notes, to illustrate the morphology (pp 67-94). A Romany-English lexicon follows, together with some shorter word-lists(pp 95-202) . The lexicon excludes those loan-words which are freely formed by stated rules from Turkish and Bulgarian, languages with which the people are familiar. Finally phonological rules are given which conver the symbols used up to this point into a broad phonetic transcription (pp 203-211), and a text in parallel phonological and phonetic transcription illustrates the application of these rules (pp 212-219). A concise bibliography concludes the study.

Catalisadores Ziegler-Natta (Z-N) de 4ª geração são preparados com suporte de dicloreto de magnésio com morfologia controlada, obtidos a partir de adutos etanólicos de dicloreto de magnésio (MgCl2.nEtOH). O objetivo deste trabalho foi otimizar o balanço entre as variáveis independentes concentração de reagentes, velocidade de agitação da emulsão e pressão de transferência, na preparação do aduto com controle morfológico. Os adutos etanólicos com controle da morfologia esférica foram preparados pela transferência controlada do aduto fundido a 125 ºC e precipitação por resfriamento brusco (quenching) em não-solvente a – 50 ºC, utilizando o método Controlled Turbulence Emulsion Method (CTEM). A ativação do MgCl2.nEtOH foi feita pela rota química para remoção do etanol e consequente aumento da área superficial do suporte. Os adutos foram preparados com razão molar EtOH/MgCl2 de 3,5 ou 63% (p/p) de etanol. Os experimentos foram realizados segundo planejamento fatorial 23 a dois níveis e ponto central replicado. As variáveis dependentes foram o diâmetro médio e distribuição de tamanho das partículas do suporte, densidade aparente compactada, morfologia e teor de álcool incorporado no aduto. Os catalisadores Z-N’s foram obtidos a partir dos suportes tratados com TiCl4 e um doador de elétrons interno, e testados em polimerização padrão de propileno. Foi observado que o controle do tamanho (diâmetro médio) da partícula do suporte é altamente dependente da velocidade de transferência, controlada pela pressão no reator de fusão. A concentração do reagente ([MgCl2]) teve efeito significativo nas quatro variáveis dependentes. A velocidade de agitação no reator de fusão ou da emulsão do aduto fundido teve efeito significativo somente na morfologia do suporte, sendo este efeito menor que o observado para a pressão de transferência. A velocidade de agitação não teve significância no processo de transferência CTEM, sendo este mais suscetível a variação da pressão no reator. / 4th Generation Ziegler-Natta catalysts (Z-N catalysts) are prepared with magnesium dichloride support with controlled morphology, obtained from ethanolic adducts of magnesium dichloride (MgCl2.nEtOH). The objective of this work was to optimize the balance between the independent variables reagent concentration, emulsion agitation speed and transfer pressure, in the preparation of the adduct with morphological control. The ethanolic adducts with spherical morphology control were prepared by controlled transfer of the molten adduct at 125 °C and quenching in nonsolvent at - 50 °C using the Controlled Turbulence Emulsion Method (CTEM). The activation of MgCl2.nEtOH was done by chemical route to remove the ethanol and consequently increase the surface area of the support. The adducts were prepared with EtOH/MgCl2 molar ratio of 3.5 or 63% (w/w) ethanol. The experiments were performed according to factorial design 23 at two levels and replicated central point. The dependent variables were the mean diameter and particle size distribution of the carrier, compacted bulk density, morphology and alcohol content incorporated in the adduct. The Z-N’s catalysts were obtained from TiCl4-treated media and an internal electron donor, and tested in standard polypropylene polymerization. It has been observed that size control (median diameter) of the carrier particle is highly dependent on the transfer rate, controlled by the pressure in the fusion reactor. The concentration of the reagent ( [MgCl2] ) had a significant effect on the four dependent variables. The stirring rate in the melt reactor or the cast adduct emulsion had significant effect only on the morphology of the support, this effect being smaller than that observed for the transfer pressure. The stirring speed was not significant in the CTEM transfer process, which is more susceptible to pressure variation in the reactor.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This study aims to evaluate the effects of plant growth regulator trinexapac-ethyl on rice cultivars, checking agronomically feasible dose and the effect of these doses on the morphology of plants on yield components and on reducing lodging plant. In this sense, two trials were held, one in the field to evaluate the effects of doses of trinexapac-ethyl on yield components over the biological cycle, about flowering. The second study was performed in greenhouse. The objective is evaluate the effects of increasing doses of trinexapac-ethyl on the morphology of plants of two cultivars of rice: a japonica cultivar (Bojurú) and one Indica cultivar (IRGA 422 CL). Experimental results show that the plant growth regulator trinexapac-ethyl applied in increasing doses, causes changes in the morphology of plants, shortening between-us, reducing plant height, leaf area and interfering in shoot dry mass, reducing bedding plants and interfering negatively in yield components, especially in the percentage of whole grains and broken grains. / Este estudo tem por objetivo avaliar os efeitos do regulador de crescimento Trinexapac-ethyl sobre cultivares de arroz irrigado, verificando o efeito de doses crescentes do ingrediente ativo sobre a morfologia de plantas, sobre os componentes do rendimento e sobre a redução de acamamento de cultivar potencialmente acamadora. Neste sentido, dois ensaios foram realizados, um em campo, com o objetivo de avaliar os efeitos de doses e épocas de aplicação do Trinexapac-ethyl sobre os componentes do rendimento, sobre o ciclo biológico, sobre a floração, e sobre o acamamento de plantas e outro, em casa-de-vegetação, para avaliar os efeitos de doses crescentes do Trinexapac-ethyl sobre a morfologia de plantas de duas cultivares de arroz irrigado, uma cultivar japônica (Bojurú) e outra cultivar indica (IRGA 422 CL). Os resultados experimentais permitem verificar que o regulador de crescimento Trinexapac-ethyl, aplicado em doses crescentes, provoca alterações na morfologia de plantas, encurtando entre-nós, reduzindo a altura de plantas, interferindo negativamente na área foliar e na fitomassa seca da parte aérea, reduzindo o acamamento de plantas e interferindo negativamente nos componentes do rendimento, principalmente no percentual de grãos inteiros e grãos quebrados.

No 1º dia de vida, os pintos foram tratados com MC antes e depois da infecção por SE. Durante todo o período experimental as condições clínicas, assim como a taxa de mortalidade foram observadas. No 1º, 3º, 5º e 7º dias pós infecção (dpi) quatro aves de cada sexo/tratamentos foram sacrificadas por meio de deslocamento cervical para obtenção de amostras do ceco para análises morfológicas (histologia e microscopia eletrônica de varredura), morfométricas e contagem do número de células inflamatórias e células caliciformes PAS+ e AB+. Os dados mostraram alguns episódios de diarréia e quadros de depressão nos pintos infectados com SE no 5º e 7º dpi; nesse período não foi observada mortalidade. No tocante às análise morfológicas, os pintos infectados por SE respondem ao processo infeccioso com um processo inflamatório agudo no 1º dpi, e a partir do 3º dpi, o processo se cronifica. A Microbiota Cecal (MC) antes da infecção, evita as alterações morfofuncionais causadas pela bactéria nos cecos dos pintos de corte, além disso, a MC induz a proliferação de células caliciformes PAS+ e AB+ e, conseqüentemente aumenta a produção de muco, sendo um fator de proteção ao epitélio cecal / This study aimed to describe the morphological changes occurred in the caecu, of males and females broiler chickens treated with Cecal Microbiote (CM) before and after the infection with Salmonella enterica enterica serovar Enteritidis (SE) during the first week of life. On the first day of life, chickens were treated with CM before and after the infection with SE. Throughout the experimental period, the clinical conditions as much as the mortality rates were observed. On 1st, 3rd, 5th and 7th days post infection (dpi), four birds of each sex/treatment were slaughtered by cervical dislocation in order to obtain samples from the caecum for morphological analysis (histology and scanning electron microscopy), morphometrical analysis and counting of the number of inflammatory and goblet cells PAS+ and AB+. The data showed some diarrhea episodes and depression symptoms in the chickens infected with SE on 5th and 7th dpi; in this period it was not observed any mortality. Concerning the morphological analysis, the chicks infected with SE respond to infectious process with and acute inflammatory process on 1st dpi and after the 3rd dpi the process gets chronicle. The Cecal Microbiote (CM) prior to infection avoid the morphological and functional alterations caused by the bacteria in broiler chickens caecum, in addition, the CM induces the proliferation of goblet cells PAS+ and AB+ and consequently increases mucus production being a protection factor to the caecum epithelium

Foram utilizados 288 leitões de 7 dias de idade e 2,57 ± 0,05 kg de peso, distribuídos no delineamento em blocos casualizados, com quatro dietas experimentais, seis repetições e doze leitões por unidade experimental. As dietas experimentais pré-inicial I (7 a 21 dias), pré-inicial II (22 a 35 dias) e inicial I (36 a 49 dias de idade) foram: dieta controle (DC)–sem inclusão de plasma e ou extrato de levedura; dieta plasma (PL)- inclusões de 6, 4 e 2% de plasma; dieta extrato de levedura (EL)-inclusões de 6, 4 e 2% de extrato de levedura, e dieta plasma + extrato de levedura (PL+EL)-inclusões de 3, 2 e 1% de plasma e extrato de levedura, respectivamente. Dos 50 aos 63 dias de idade, todos os leitões receberam uma mesma dieta. Aos 28 e aos 49 dias de idade, foram abatidos seis animais de cada dieta experimental, para avaliações da estrutura e ultraestrutura do duodeno e jejuno. Observou-se que de 7 a 21 e de 7 a 28 dias de idade, nenhuma variável de desempenho foi afetada (P>0,05), mas de 7 a 35 dias, o GDP foi maior (P<0,05) nos leitões que receberam a dieta PL + EL. De 7 a 49 e de 7 a 63 dias, notou-se maiores (P<0,05) GDP e CDR nos animais que receberam a dieta PL+EL, quando comparados aos que consumiram a dieta DC. A estrutura e a ultra-estrutura não foram afetadas (P>0,05). Conclui-se que a combinação de plasma e extrato de levedura promove ganho diário de peso superior, mas não afeta a morfologia intestinal dos leitões dos 7 aos 63 dias de idade / The aimed was to evaluate diets containing plasma and or yeast extract on performance (DWG - daily weight gain, DFI - daily feed intake and FC -feed conversion) and the intestinal morphology of the piglets from 7 to 63 days of age. There were used 288 piglets from 7 days of age and 2.57 ± 0.05 kg, distributed in a randomized block design with four treatments, six replicates and twelve piglets in each experimental unit. The experimental units pre-initial I (from 7 to 21 days of age), preinitial II (from 22 to 35 days of age) and initial I (from 36 to 49 days of age) were: control diet (CD) - without including plasma and / or yeast extract, plasma diet (PL) - inclusions of 6, 4 and 2% plasma; yeast extract diet (YE) - inclusions 6, 4 and 2% of yeast extract, and plasma diet + yeast extract (PL + YE) - additions of 3, 2 and 1% of plasma and yeast extract, respectively. From 50 to 63 days of age, all animals received the same diet. At 28 and 49 days of age, were killed six animals of each experimental diet for evaluations of the structure and ultra structure of the duodenum and jejunum. It was observed that from 7 to 21 and from 7 to 28 days of age, no variable performance was affected (P> 0.05), but from 7 to 35 days of age, the DWG was higher (P <0.05) on the piglets fed with diet PL + YE. From 7 to 49 and from 7 to 63 days of age, it was noted (P <0.05) DWG and DFI in the animals fed with diet PL + YE compared to those fed with the diet CD. The structure and ultra structure were not affected (P> 0.05). We conclude that the combination of plasma and yeast extract promotes a superior weight gain, but does not affect the intestinal morphology of pigs from 7 to 63 days of age
