No. of bitstreams: 2 Dissertação - Beryl Eirene Lutz de Moura - 2017.pdf: 12051632 bytes, checksum: 125bb88e7ee0e8eabcbbaf1161a7c516 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Previous issue date: 2017-03-29 / The family Cucurbitaceae Juss. is include in Cucurbitales order in the clade Eurosids I, 2295 spp., included in 129 tropical and temperate genera distributed in seven families of different morphological and ecological characteristics. The family has 98 genera and 975 species. In Brazil is represented by about 30 genera and 157 species. This work deals with the taxonomic study of plants of the Cucurbitaceae family Juss. found in the State of Goias, Brazil to contribute information to update the Flora of Brazil. Exsiccatae analyzes were performed deposited in national and international herbaria and conducting expeditions in the study area. 19 genera and 40 species in the area were located, so 09 genera and 28 species of native plants. Relative to native plants, Cayaponia Silva Manso gender had a greater number of species (8 spp.), followed by Melothria L. (6 spp.), Gurania (Schltdl.) Cogn. (4 spp.), Ceratosanthes Adans. (3 spp.) Psiguria Neck ex. Arn.and Sicyos L. (2 spp.), and the genres Melothrianthus Mart. Crov., Siolmatra Baill, Wilbrandia Silva Manso, are represented by only one species each. Pollen morphology of six native and two sub-spontaneous species of Cucurbitaceae occurring in the state of Goias, Midwest Region of Brazil, were analyzed with the goal of understanding the palynology and taxonomy of selected species. Pollen grains were acetolyzed, measured, described, photographed and electromicrographed. Analysis under the SEM was used to elucidate questions about the ornamentation of the exine. Pollen grains are in monads in Cayaponia podantha Cogn., Ceratosanthes tomentosa Cogn., Luffa operculata (L.) Cogn., Melothria campestris (Naudin) H. Schaefer & S. S. Renner, Momordica charantia L., Wilbrandia hibiscoides Silva Manso or tetrads in Gurania lobata (L.) Pruski and Psiguria umbrosa (Kunth) C. Jeffrey; average size, large or very large in monads and very large in tetrads. The openings ranged from pores in Cayaponia podantha, colpores in other monads and pores in tetrads. Regarding ornamentation, spiny sexine were registered in Cayaponia podantha, perforated sexine in Melothria campestris, micro-reticulated sexine in Gurania lobata and Psiguria umbrosa and reticulated sexine in other taxa. Results allowed the distinction between genera, indicating that the pollen morphology contributes to the taxonomic studies and the family is considered eurypalynous. These data emphasize the importance of pollen morphology for the diagnosis of genera into Cucurbitaceae. / A família Cucurbitaceae Juss. está inclusa na ordem Cucurbitales, no clado Eurosídeas I, com 2295 spp., inclusas em 129 gêneros tropicais e temperados, distribuídos em sete famílias de diferentes características morfológicas e ecológicas. A família Cucurbitaceae possui 98 gêneros e 975 espécies. No Brasil é representada por cerca de 30 gêneros e 157 espécies. O presente trabalho trata do estudo taxonômico e morfopolínico das espécies nativas da família Cucurbitaceae Juss. encontradas no Estado de Goiás, Brasil a fim de contribuir com informações para atualização da Flora do Centro Oeste e do Brasil e com novos dados para a palinotaxonomia. Para o estudo taxonômico foram realizadas análises de exsicatas depositadas em herbários nacionais e internacionais e realização de expedições na área de estudo. Foram localizados 19 gêneros e 40 espécies para a área, sendo até o momento, compreendendo 09 gêneros e 28 espécies de plantas nativas, 10 gêneros em 13 espécies consideradas cultivadas ou subespontâneas. Em relação às plantas nativas, o gênero Cayaponia Silva Manso apresentou um número maior de espécies (9 spp.), seguido de Melothria L. (6 spp.), Gurania (Schltdl.) Cogn. (4 spp.), Ceratosanthes Adams (3 spp.), Psiguria Neck ex. Arn. e Sicyos L. (2 spp.), e os gêneros Melothrianthus Mart. Crov., Siolmatra Baill. e Wilbrandia Silva Manso são representados por apenas 1 espécie cada um deles. Analisou-se a morfologia polínica de seis espécies nativas e duas subespontâneas de Cucurbitaceae ocorrentes no estado de Goiás, região Centro-Oeste do Brasil; com o objetivo de entender a palinologia e taxonomia de espécies selecionadas de Cucurbitaceae. Os grãos de pólen foram acetolizados, mensurados, descritos, foto e eletromicrografados. A análise sob o MEV foi utilizada visando a elucidação de dúvidas sobre a ornamentação da exina. Constatouse que os grãos de pólen são em mônades em Cayaponia podantha Cogn., Ceratosanthes tomentosa Cogn., Luffa operculata (L.) Cogn., Melothria campestris (Naudin) H. Schaefer & S. S. Renner, Momordica charantia L., Wilbrandia hibiscoides Silva Manso ou tétrades em Gurania lobata (L.) Pruski e Psiguria umbrosa (Kunth) C. Jeffrey; tamanho médio, grande ou muito grande nas mônades e muito grande nas tétrades. As aberturas variaram de poro em Cayaponia podantha, cólporo nas demais mônades e poro nas tétrades. Em relação à ornamentação, foram registradas sexina espinhosa em Cayaponia podantha, perfurada em Melothria campestris, microrreticulada em Gurania lobata e Psiguria umbrosa e reticulada nos demais táxons. Os resultados permitiram a distinção entre os gêneros, indicando que a morfologia polínica contribui para os estudos taxonômicos e a família pode ser considerada euripolínica. Esses dados enfatizam a importância da morfologia polínica para o diagnóstico de gêneros em Cucurbitaceae.

L'évaporation dans le bilan hydrologique des étangs du Centre-Ouest de la France (Brenne et Limousin) / Evaporation in water balance of ponds in the French Midwest (Brenne and Limousin)

Aldomany, Mohammad 12 September 2017 (has links)
L’effacement des plans d’eau (petits ou grands) du continuum hydrographique est le nouveau dogme français lié à l’interprétation de la Directive Cadre européenne sur l'Eau (DCE-2000) dans la Loi sur l’Eau et les Milieux Aquatiques (LEMA-2006). En effet, cette stratégie se base sur des idées ne reposant sur aucune mesure exacte de l’influence des plans d’eau, supposée néfaste, sur la quantité d’eau s’écoulant dans les réseaux hydrographiques aval. Face à ce paradoxe notable entre réglementation appliquée et absence de mesures directes de l'évaporation des étangs de France métropolitaine, il apparaît un double besoin, tant en géographie fondamentale qu’en recherche appliquée, pour une étude détaillée sur l'évaporation et le bilan hydrologique des étangs.Sur le plan méthodologique, cette étude montre que le bac flottant en plastique transparent est l’outil le plus à même de mesurer l'évaporation des étangs. Sur le plan conceptuel, le travail intensif de terrain a conduit à établir une nouvelle formule empirique ''Aldomany'' qui peut fournir des estimations fiables de l'évaporation des plans d'eau peu profonds à l'échelle annuelle, mensuelle et journalière en utilisant seulement des données météorologiques facilement accessibles. Dans une optique de gestion, cette étude montre que la perte en eau provoquée par un étang s’apparente à celle d’une chênaie de même superficie et que les propos à charge tenus contre les étangs méritent d’être nuancés, les étangs de la Brenne étant bien en partie responsables de l'étiage estival de la Claise, alors que les étangs limousins jouent un rôle plutôt positif en assurant un bon débit estival du réseau hydrographique de cette région. / The erasure of water bodies (large or small) of the hydrographic continuum is the new French dogma related to the interpretation of the European Water Framework Directive (WFD-2000) in the Water and Environment Act (LEMA-2006). In fact, this strategy is based on ideas that are not based on any exact measure of the influence of the supposedly harmful water bodies on the amount of water flowing into the downstream hydrographic networks. In view of this remarkable paradox between applied regulation and the absence of direct measurements of the evaporation of metropolitan France's ponds, there appears to be a dual need in both basic geography and applied research for a detailed study on evaporation and the water balance of ponds.Methodologically, this study shows that the evaporation floating pan constructed of transparent plastic is the most suitable tool for measuring the evaporation of ponds. Conceptually, intensive field work has led to the development of a new empirical formula ''Aldomany'' that can provide reliable estimates of the evaporation of shallow water bodies at on an annual, monthly and daily basis using only readily available meteorological data. From a management perspective, this study shows that the loss of water caused by apond is similar to that of an oak has the same area and that the statements against the ponds should bere considered, the ponds of La Brenne being partly responsible for the summer low water of the Claise,while the Limousin's ponds play a rather positive role in ensuring a good summer flow of the hydrographic network of this region.

Discours et identité d'un migrant canadien-français au XIXe siècle : la trajectoire de Sam Gravel

Joubert, Joanie January 2012 (has links)
Dans cette étude, nous examinons la trajectoire d’un migrant canadien-français au XIXe siècle, Sam Gravel, ainsi que les changements identitaires qu’il subit en fonction des lieux de migration qu’il atteint. Sam se rend en Nouvelle-Angleterre en 1882 pendant quelques mois. Il revient brièvement au Québec puis immigre dans l’Ouest canadien en 1883 et y demeurera jusqu’en 1891. Il s’établira ensuite dans le Midwest américain jusqu’en 1897. Il rentrera finalement au Québec et s’installera dans le village de Somerset en 1897. Il décède en 1899 d’une noyade à Québec. C’est en analysant son parcours migratoire, son mode d’établissement et son discours que nous pouvons déterminer comment s’insère sa migration dans les courants de migration du XIXe siècle. Est-ce que ses choix sont représentatifs de la majorité des migrants de l’époque ? Comment ces choix influencent-ils sa perception des autres groupes ethniques ainsi que ses valeurs religieuses et familiales? Sam tient un discours qui se rapproche beaucoup de celui des Canadiens français de l’époque alors qu’il se trouve dans l’Ouest canadien et tend à s’en dégager alors qu’il atteint le Midwest américain.

Distribuição geográfica das chuvas no Estado de Goiás e Distrito Federal: dinâmica e aplicações nos estudos rítmicos / Geographic distribution of rains in the State of Goiás and Federal District: dynamics and applications in rhythmic studies

Gustavo Zen de Figueiredo Neves 16 March 2018 (has links)
O objetivo deste trabalho foi de compreender a distribuição espaço-temporal das chuvas no Estado de Goiás e o Distrito Federal, e suas principais características quali-quantitativas no período de 1975 a 2015. A metodologia baseou-se no levantamento do referencial teórico-metodológico; obtenção dos dados; espacialização dos postos e de séries temporais consistentes; tratamento estatístico, análise da distribuição mensal da precipitação, dos eventos de extremos climáticos e a identificação de \"anos-padrão\". Elaborou-se a climatologia das frentes frias e a representação cartográfica da distribuição das chuvas anuais e sazonais na área de estudo. Os resultados observados apontam para uma variabilidade e irregularidade da distribuição das chuvas entre a região norte de Goiás e valores ligeiramente mais reduzidos no sentido sudoeste do Estado de Goiás. Os mecanismos de precipitação são impostos pela atuação dos sistemas atmosféricos intertropicais. Ressalta-se ainda interação do Planalto Central Brasileiro na participação das chuvas locais ocasionadas pelos efeitos termodinâmicos de superfície e dos aglomerados convectivos locais provocados pela Zona de Convergência do Atlântico Sul. Destacamse a importância na atualização do conhecimento climático do Estado de Goiás e Distrito Federal e as possibilidades que se ampliam para um futuro próximo. / The objective of this work was to understand the spatial-temporal distribution of rainfall in the State of Goiás and the Federal District, and its main qualitative and quantitative characteristics from 1975 to 2015. The methodology was based on the survey of the theoretical-methodological reference; obtainment the data; spatialization of stations and consistent time series; statistical treatment, analysis of the monthly distribution of precipitation, climatic extreme events and the identification of \"standard years\". The climatology of the cold fronts and the cartographic representation of the annual and seasonal rainfall distribution in the study area were elaborated. The observed results point to a variability and irregularity of the rainfall distribution between the northern region of Goiás and slightly lower values in the southwest direction. Precipitation mechanisms are imposed by the performance of the atmospheric systems equatorials and intertropicals. It is also worth mentioning the interaction of the Brazilian Central Plateau in the participation of the local rains caused by the thermodynamic effects of the surface and of the local convective agglomerates caused by the Convergence Zone of the South Atlantic. The importance of updating the climatic knowledge of the State of Goiás and District and the possibilities that amplify for the near future.

Political Participation Among Latinos: Why It Matters and How to Increase It

Cassey H Suthers (8788190) 01 May 2020 (has links)
<p><a>This study sought to identify obstacles and challenges that impact political participation and involvement among Latino voters. At the same time, it explored how the Latino Democrats of Allen County (LDAC), a constituency caucus in a primarily conservative area, could address such barriers to engage Latinos from the area politically (specifically in support of the Democratic party). Social Identity Theory provided a backdrop from which to examine the challenges and obstacles that Latinos face to participating in local government. By exploring these questions from the perspective of Social Identity Theory, I examined how a demographic in a primarily conservative area grapples with their political participation. Findings suggest that Latinos struggle with their participation due to lack of awareness about opportunity, low political efficacy, lack of trust in the political process and those that facilitate it, and lack of education about how the political process works. Literature on communication strategies and techniques used by organizations and groups with similar structures and goals provided a roadmap for constructing a functional and meaningful strategic communication plan for LDAC based on the findings from this study.</a></p>

Vicious Children and Other Stories

Aaron Dell (8802530) 06 May 2020 (has links)
<p><i>Vicious Children and Other Stories</i> contains four stories, each concerned in their own way with boyhood, friendship, masculinity, and alienation. <i>Vicious Children</i> is a novella that follows two brothers, Jesse and Danny, as they explore a time in which their roles in their community and family are changing. In “What Else Are We Going to Do With Them?” a group of young boys fight betta fish to the death, leaving one of the boys, Josh, questioning his enjoyment of the fight. “Gash” deals with the main character, Adam’s, memory of a traumatic event in contrast to the lighthearted way he and his family tell the story in the present. Finally “Don’t You Have a Name?” follows Zach, a content moderator for a social media platform, who finds that, although he excels at the job, it comes at the cost of his mental health.</p>

An Exploration of College Attitudes among Sioux Falls High School Students

Duesterhoeft, Kristin 08 1900 (has links)
Since the recession of 2008, there has been an increased scrutiny of higher education, with little research done on how this affects high school students' college search process. This study seeks to understand how college perceptions are formed and how they affect the college decision process of high school students in Sioux Falls, South Dakota. In order to gain a holistic perspective of this process, this study utilized a mixed method approach of analyzing public data, conducting interviews with community members and students, conducting a focus group with high school guidance counselors, and administering a survey to high school students. This study found that students in this area form their perceptions of college in three distinct phases and that these phases affect a student's college priorities. Special attention was given to how academics, cost and location contributed to a student's overall college decision. These findings can be used to assist faculty and staff at higher education institutions in creating effective messaging and programming that relate to this group of students.
