The Birthday of the Infanta: An Early Twentieth-Century Chicago Ballet Contextualized

Lanctot, Heather, Lanctot, Heather January 2012 (has links)
The Birthday of the Infanta, a ballet that was created by John Alden Carpenter, Adolph Bolm, and Robert Edmond Jones, was performed at the Auditorium Theatre in Chicago on December 23, 1919 and the Lexington Theatre in New York on February 23, 1920. Despite the positive reviews from daily papers and music journals alike the ballet was only revived once and is not a part of a known ballet repertoire. Although musicologist Howard Pollack discusses The Birthday of the Infanta briefly in his biography of John Alden Carpenter my analysis serves, through its exploration of both primary and secondary sources, to create a more complete and thorough dialogue through the examination of the social, economic, political and artistic factors surrounding the ballet. This analysis also helps to create a better understanding of ballet’s place in America in the early twentieth century.

Assembly a anotace genomu včely Ceratina nigrolabiata s obourodičovskou péčí / Genome Assembly and Annotation of Biparental Bee Ceratina nigrolabiata

Fraňková, Tereza January 2020 (has links)
Biparental care in Hymenoptera is a little studied behaviour. This kind of parental care was discovered and the ethological aspect described in the bee Ceratina nigrolabiata from the Czech Republic and is well understood on the ethological level. However, biparental care is not a common behaviour and the lack of genomic studies of this behaviour complicates the understanding of the origin of the biparental care and its underlying pathways on the genomic and physiological level. This master's thesis presents the genome analyses of a biparental bee Ceratina nigrolabiata. It consists of a brief summary of the known parental behaviour across insects, characteristics of the genus Ceratina, summary of the used genomic methods and presents a candidate genes for the transcriptomic study of the biparental behaviour of Ceratina nigrolabiata. Key words: biparental care, genomics, Hymenoptera, Insecta, Ceratina, small carpenter bees

Effects of nectar robbing by Xylocopa californica on Chilopsis linearis (Bignoniaceae)

Pfister, Rachel Walker, 1940- January 1989 (has links)
The interaction between Xylocopa californica and Chilopsis linearis was used to test the hypothesis that nectar robbing is costly to plants. No evidence for these costs, either in terms of decreased pollination or increased energy demands, was found. In fact, the mean number of seeds per fruit and the mean individual weight of seeds per fruit was higher from fruits that developed from robbed flowers than from fruits that developed from unrobbed flowers, indicating that the presence of Xylocopa californica enhanced pollination. Chilopsis linearis pollen was isolated from the tips of the abdomens of robbing Xylocopa californica and it was determined that these bees could be transferring pollen from flower to flower as they position themselves to rob. This association was found to be one of mutual benefit rather than one of exploitation.

Due to the self-incompatibility of some species of agricultural interest, cross-pollination is required and the limiting of pollinating species such affects its production. The yellow passion fruit (Passiflora edulis f. flavicarpa.), a selfincompatible specie is dependent on cross-pollination to form fruit. Thus, the general aim of this study was to study the biology of pollination and reproduction in P. edulis f. flavicarpa, emphasizing the efficacy of pollinators for this specie. The specific aims were: 1) to evaluate the richness, visitation frequency and the behavior of visitors in Passiflora edulis f. flavicarpa flowers.; 2) to compare the efficacy in the formation of fruits and seeds of P. edulis f. flavicarpa through individual and two visits by Xylocopa frontalis with manual crosspollination and natural pollination and 3) assess whether there is pollen limitation through comparison between natural and manual cross-pollination. Visitors were observed during the flowering period, from January to April 2015, totaling 106 hours of observations. For fruiting testing and seed counts: 1) manual cross pollination (n = 37 flowers); 2) natural pollination (n = 52 flowers); 3) pollination by single visit of X. frontalis (n = 41 flowers) and 4) pollination by two visits of X. frontalis. Were identified bee species of Apis, Bombus, Centris, Epicharis, Eulaema, Melipona, Oxaea, Trigona and Xylocopa genera, Apidae, being also observed an individual belonging to Halictidae family. Insects belonging to other orders were also observed, including different species of butterflies (Lepidoptera), bugs (Hemiptera), flies (Diptera), beetles (Coleoptera) and the presence of family Trochilidae hummingbirds. The specie A. mellifera (thief behavior) and X. frontalis (predominantly pollinator behavior) were the most frequent in the plantation with 58.11% and 30.20% respectively of occurrence. Regarding pollination tests, we observed the formation of fruits in all the treatments. Flowers of manual cross-pollination obtained the highest fruiting rate when compared to other treatments. The fruiting rate through manual cross-pollination was significantly higher than that obtained in natural conditions (X2 = 12.676; degree of freedom = 1; p <0.05) indicating that there is pollen limitation in natural pollination. Regarding the number of seeds, an analysis of variance (ANOVA) indicated no significant difference between the mean number of seeds produced in different reviews pollination. Conclude that there is richness of floral visitors specie in the study area, and that between them, the main pollinator species are those with larger, mainly bees belonging to the genus Xylocopa. Larger fruiting rates obtained by manual cross-pollination treatment suggest that more than one visit is needed to promote greater production rate in passion fruit crops. / A polinização é um serviço ecossistêmico, responsável por aumentar a quantidade e a qualidade dos frutos e sementes formados. Devido à autoincompatibilidade de algumas espécies de interesse agrícola, a polinização cruzada torna-se necessária e a limitação de polinizadores nessas espécies afeta a sua produção. O maracujá-amarelo (Passiflora edulis f. flavicarpa Deg.), por ser uma espécie autoincompatível, é dependente da polinização cruzada para a formação de seus frutos. Dessa forma, o objetivo geral desse estudo foi estudar a biologia da polinização e a reprodução de P. edulis f. flavicarpa, enfatizando a eficácia do principal polinizador dessa espécie. Os objetivos específicos foram: 1) avaliar a riqueza, frequência de visitas e o comportamento dos visitantes em flores de Passiflora edulis f. flavicarpa Deg.; 2) comparar a eficácia na formação de frutos e sementes em P. edulis f. flavicarpa por meio de visitas individuais e duas visitas de Xylocopa frontalis com a polinização cruzada manual e a polinização natural e 3) avaliar se há limitação polínica por meio da comparação entre a polinização cruzada manual e a polinização natural. Os visitantes florais foram observados durante o período de floração, de janeiro a abril de 2015, totalizando 106 horas de observações. Para avaliar a eficácia da polinização e a limitação polínica foram realizados quatro tratamentos distintos de polinização: 1) Polinização cruzada manual (n=37 flores); 2) Polinização natural (n=52 flores); 3) Uma visita de X. frontalis (n=41 flores) e 4) Duas visitas de X. frontalis (n=31 flores). Para cada tratamento foi avaliado a formação de frutos e a produção de sementes. Foram identificadas espécies de abelhas dos gêneros Apis, Bombus, Centris, Epicharis, Eulaema, Melipona, Oxaea, Trigona e Xylocopa (Apidae), sendo também observado um indivíduo pertencente a família Halictidae. Insetos pertencentes a outras ordens também foram observados, entre eles, diferentes espécies de borboletas (Lepidoptera), percevejos (Hemiptera), moscas (Diptera), besouros (Coleoptera) e a presença de beija-flores da família Trochilidae. As espécies A. mellifera (comportamento pilhador) e X. frontalis (comportamento predominantemente polinizador) foram as mais frequentes na plantação com 58,11% e 30,20% das visitas respectivamente. Em relação aos tratamentos de polinização, verificamos que houve formação de frutos em todos os tratamentos realizados. Flores de polinização cruzada manual obtiverem a maior taxa de frutificação quando comparada aos demais tratamentos. A taxa de frutificação por meio da polinização cruzada manual foi significativamente maior que a obtida em condições naturais (X2 = 12,676; grau de liberdade = 1; p<0,05) indicando que há limitação polínica na polinização natural. Em relação à quantidade de sementes, a análise de variância (ANOVA) não indicou diferença significativa entre as médias do número de sementes produzidas nos diferentes tratamentos. Concluímos que há riqueza de espécies visitantes florais na área estudada, e que entre elas, as principais espécies polinizadoras são aqueles que possuem maior tamanho, principalmente as abelhas do gênero Xylocopa. Maiores taxas de frutificação obtidas por meio do tratamento de polinização cruzada manual sugerem que mais de uma visita é necessária para aumentar a produtividade.

Projektering av takkonstruktioner med förindustriella träförband : beräkning och provning av hophuggningar

Röjerås, Anders January 2019 (has links)
In earlier wood constructions, the method of joining the parts was by the carpenter joint. There are many different kinds of carpenter joints. The kind of carpenter joint that was used was partly due to the type of building, but also to local variations in building tradition.  The industrialization at the end of the 19thcentury led to new construction technology with new types of joints. It gradually became more difficult for the craftsmen to compete with mass-produced standard joints with screws and nails. During the latter half of the 20thcentury, it once again began to become popular with the carpenter joint. New technology in the wood industry began to make carpenter joints competitive.  Modern technology with modeling of geometries has made it possible to analyze and optimize structures and joints in a new way. Verification through tests has also led to increased understanding of wood joints.  Calculation of the load bearing capacity in carpenter joints is possible by applying calculation rules in Eurocode.   The purpose with this study is to verify strength calculations for a traditional carpenter joint.  An analysis of an imagined timber frame and roof truss was made in a calculation program to assess in a rough manner what section forces the structure was subjected to.   A dovetail joint in the roof truss shown in fig. 1 was chosen for further analysis.  Manual calculation of the load bearing capacity in the dovetail joint was made. Verification of the calculations was then done through strength tests in a lab.   The study shows that it is possible to calculate the load bearing capacity in a dovetail joint and that account must be taken to eccentricities in the joint and varying wood quality. / I äldre träbärverk var metoden för sammanfogning av virkesdelar hophuggningen. Det finns en mängd olika typer av hophuggningar. Vilken typ av hophuggning som användes berodde dels på byggnadstypen men även på lokala variationer i byggnadstradition. Industrialiseringen under slutet på 1800-talet bidrog till ny byggteknik med nya typer av förband. Det blev efter hand svårare för timmermännen att konkurrera med massproducerade standardförband med skruv och spik. Under senare halvan av 1900-talet började det åter bli populärt med hophuggningen. Ny teknik inom träindustrin började åter göra timmerförband konkurrenskraftiga. Modern teknik med modellering av geometrier har även gjort det möjligt att på ett nytt sätt analysera och optimera bärverk och förband. Verifiering genom tester har också lett till ökad förståelse av timmerförband. Beräkning av bärförmågan i hophuggningar är möjligt genom tillämpning av beräkningsregler i Eurokod. Syftet med detta arbete är att verifiera hållfasthetsberäkningar för ett traditionellt timmerförband.  En analys av en tänkt timmerram och takstol gjordes i ett beräkningsprogram för att på ett överslagsmässigt sätt bedöma vilka snittkrafter konstruktionen utsattes för. Ett laxförband i takstolen som visas i fig. 1 valdes ut för vidare analys. Manuell beräkning av bärförmågan i laxförbandet gjordes. Verifiering av beräkningarna gjordes därefter genom hållfasthetsprovning av förbandet i laborationslokal. Studien pekar mot att det går att med tillförlitlighet beräkna bärförmågan för ett traditionellt laxförband och att hänsyn skall tas till excentriciteter och varierande virkeskvalitet.

We intend to understand the mathematic knowledge involved in this activity. The second objective is to take this kind of knowledge to the classroom, mainly, considering the context of teachers. The carpenters interviewed, belong to a social group that develop a kind of a job like a craftsmen. We interest in community activity because they are very easy to find it. This study started considering: Etnomathematic s researches, a kind of successful job done by many teenagers students using a cupboard, and because there is no researchers about this in a regular classroom. In some points this work involves: how the public teacher would like to find a new knowledge, how a master student has an interest in a performance of a new teachers, and how a carpenter manual can be used in a basic school / Este trabalho desenvolveu um estudo e análise por meio do programa em Etnomatemática sobre a atividade de marceneiro. Nele procuramos compreender o conhecimento matemático envolvido na atividade de marceneiro e transformar este conhecimento para a sala de aula como possibilidade num contexto de formação de professor de matemática. Os marceneiros entrevistados que fizeram parte desta pesquisa compõem o grupo social que desenvolve seu trabalho quase de forma artesanal. Interessamo-nos por esta atividade, que de certa forma é encontrada nas comunidades, sendo acessível de ser pesquisada, objetivando a nossa proposta para a educação no contexto da matemática. O presente trabalho teve como pontos iniciais: estudos realizados a respeito de Etnomatemática e um trabalho desenvolvido com alunos de uma 8ª série do Ensino Fundamental II, em 1999, quando foi desenvolvida uma atividade em que os alunos deveriam desenhar um armário para cozinha, ao qual nos proporcionou conhecimento, principalmente de parte da Geometria. Os grupos de alunos desenvolveram o desenho e a maquete do armário. A partir dessa atividade demos continuidade ao trabalho, principalmente, o estudo de figuras planas, suas propriedades, áreas, semelhança, congruência, transformação de unidades de medidas, cálculo de volume, etc. Como professor de matemática e aluno da Pós-Graduação em Educação Matemática, tinha interesse em buscar novos conhecimentos inseridos na contextualização da formação do professor, através de uma análise sobre a atividade de marceneiro, por meio de projetos e material de apoio didático do curso de marcenaria. A presente pesquisa revelou resultados em que as considerações a respeito da atividade de marceneiro possam ser desenvolvidas em sala de aula e dessa forma proporcionar meios para que o aluno deva ter acesso a mais uma forma de obter conhecimento e de maneira contextualizada
