A Modified Clenshaw-Curtis Quadrature Algorithm

Barden, Jeffrey M. 24 April 2013 (has links)
This project presents a modified method of numerical integration for a “well behaved� function over the finite interval [-1,1]. Similar to the Clenshaw-Curtis quadrature rule, this new algorithm relies on expressing the integrand as an expansion of Chebyshev polynomials of the second kind. The truncated series is integrated term-by-term yielding an approximation for the integral of which we wish to compute. The modified method is then contrasted with its predecessor Clenshaw-Curtis, as well as the classical method of Gauss-Legendre in terms of convergence behavior, error analysis and computational efficiency. Lastly, illustrative examples are shown which demonstrate the dependence that the convergence has on the given function to be integrated.

FREITAS, A. R. 12 July 2016 (has links)
Made available in DSpace on 2018-08-01T22:35:03Z (GMT). No. of bitstreams: 1 tese_8858_Allan Rocha de Freitas.pdf: 2507012 bytes, checksum: 7fcbdfb852b1438e207c1f30d8b303a4 (MD5) Previous issue date: 2016-07-12 / O maracujazeiro doce (Passiflora alata Curtis) é uma planta herbácea, em geral trepadeira, que apresenta folhas subcoriáceas, flores solitárias, axilares, perfumadas e frutos com polpa sucosa de sabor doce e agradável. Tradicionalmente, os pomares comerciais desta espécie são estabelecidos por mudas obtidas de sementes, sendo comum o relato de baixa porcentagem de germinação, o que pode estar associado aos mecanismos de dormência. No Brasil, o tratamento do esgoto industrial tem como consequência a grande produção de resíduo sólido, o lodo de esgoto, que é um produto decorrente do tratamento de efluentes sanitários, seja de origem doméstica ou industrial, com elevado conteúdo de matéria orgânica, composição química e biológica. O uso do lodo apresenta-se eficiente para o crescimento das plantas. No entanto, apresenta indícios de acúmulo de metais pesados no solo e na planta, além de ter potencial de impacto na saúde humana ao entrar na cadeia alimentar, por bioacumulação. Na pesquisa foram utilizadas sementes de P. alata provenientes de frutos coletados a partir de 15; 30; 45; 60; 75; e 85 dias após a antese. Avaliaram-se os extratos das sementes sobre a germinação de Lactuca sativa L. Foram determinadas as características químicas do lodo de esgoto: As, Ba, Cd, Ca, Pb, Cu, Cr, S, Mg, Mn, Hg, Mo, N, Ni, K, Se, Na, Zn, P, C orgânico e MO. Posteriormente, avaliaram-se a mutagenicidade e o acúmulo de metais pesados nas plantas tratadas com o lodo. O estádio de maturação do fruto interfere na qualidade fisiológica das sementes. A utilização do extrato do embrião das sementes de maracujá na germinação de sementes de alface determina uma menor porcentagem de germinação. O uso do lodo de esgoto eleva a concentração de elementos essenciais e matéria orgânica do solo e afeta negativamente a germinação das sementes de maracujá doce. Palavras-chave: Passiflora alata Curtis; bioacumulação; morfologia; germinação; mutagenicidade; toxidez.

Stolthet och skvaller : En komparativ analys mellan Jane Austens Stolthet och fördom och Curtis Sittenfelds Sanning och skvaller / Pride and gossip : A comparative analysis of Jane Austen's Stolthet och fördom and Curtis Sittenfeld's Sanning och skvaller

Larsson, Johanna January 2019 (has links)
This essay analyses Curtis Sittenfeld’s novel Sanning och Skvaller as an adaption of Jane Austen’s Stolthet och fördom. The purpose of this essay is to take a closer look at how the characters and the plot changes in Sittenfeld’s version compared to the original. The character analysis mainly focuses on Mr. Wickham, lady Catherine de Bourgh and Caroline Bingley as characters, as well as Mary Bennet and how her sexuality is portrayed. Elizabeth Bennet’s relationship with Mr. Darcy and the importance of a proposal and a marriage is also something that this essay analyses. The reception of the novel is something that will be addressed by highlighting some of the negative, and positive, reviews that the novel received upon publication. The discussion at the end brings up whether or not Sittenfelds novel can be classified as an adaption after changing so much of the story, how the elements in the new version changes its believability and how the problematic aspects may ruin the story.

Identificação de um peptideo antifúngico em sementes de Passiflora alata Curtis com similaridade à albumina 2S

No. of bitstreams: 1 suzanameiraribeiro.pdf: 1332777 bytes, checksum: b4c35efe19a33f78ca2cec41c685e844 (MD5) Previous issue date: 2010-06-12 / Doenças causadas por patógenos, incluindo bactérias e fungos podem gerar muitos problemas à saúde humana e à agricultura. Em cultivares economicamente importantes, tais patógenos podem contribuir para perdas significativas no rendimento da produção agrícola. Um fator agravante para esses dois cenários é o uso intensivo de compostos convencionais para combater esses patógenos, levando à seleção de microrganismos extremamente resistentes. Além disso, tais compostos podem trazer severas conseqüências ao meio ambiente bem como à saúde humana e animal. Desta forma, a busca por novos compostos capazes de controlar efetivamente bactérias e fungos patogênicos resistentes, têm sido prioritária. Por estas razões, este trabalho reporta o isolamento de uma nova proteína heterodimérica (Pa-AFP1) de sementes de Passiflora alata com propriedades antifúngicas. Pa-AFP1 foi purificada utilizando precipitação com sulfato de amônio 70-100%, subseqüente cromatografia de troca aniônica em Q-Sepharose e cromatografia de HPLC fase reversa em coluna C4. Análise da massa molecular por meio de gel Tricina-SDS-PAGE revelou uma massa molecular de aproximadamente 4.500 Da para a cadeia menor e cerca de 7.000 Da para cadeia maior totalizando um heterodímero com cerca de 11.500 Da. A massa da forma oligomérica também foi obtida por espectrometria de massa (11569. 63 Da). Análise da seqüência N-terminal mostrou alta identidade entre Pa-AFP1 e albuminas 2S, adicionando assim uma nova proteína à pequena lista de albuminas 2S com atividade antimicrobiana. Além disso, Pa-AFP1 foi capaz de inibir eficientemente o fungo filamentoso Colletotrichum gloeosporiodes, mas foi incapaz de inibir bactérias e fungos leveduriformes. Em suma, Pa-AFP1 poderá futuramente contribuir para o desenvolvimento de produtos biotecnológicos contra fungos fitopatogênicos. / Diseases caused by pathogens, including bacteria and fungi can generate many problems to human health and agriculture. In important economically cultivars, such pathogens may contribute to significant losses in yield of agricultural production. The aggravating factor for these two scenarios is the intensive use of conventional compounds to combat these pathogens, leading to selection of highly resistant microorganisms. Furthermore, these compounds can bring severe consequences to the environment, human and animal health. Thus the search for new compounds capable of effectively controlling bacteria and fungi resistant has been a priority. In this report a heterodimeric antifungal protein named Pa-AFP1, showing higher identity with the 2S albumin family, was purified by using 70-100% ammonium sulfate saturation and further purification steps such as anionic exchange Q-Sepharose chromatography associated with HPLC reversed-phase C4 chromatography. Analysis by Tricine-SDS-PAGE revealed two peptide molecular masses of approximately 4,500 Da and 7,000 Da, in the presence of β-mercapthoetanol, while by removing the reducing agent, a single protein with molecular mass of about 11,500 Da was obtained. Moreover, dimeric mass was confirmed by MALDI-TOF analyses (11,569.76 Da). The antifungal protein, named Pa-AFP1, efficiently inhibited the growth of filamentous fungi Colletotrichum gloeosporiodes, and was added to a short list of 2S albumins with antimicrobial properties. Otherwise, this same peptide showed no activity toward bacteria and yeasts. In summary, this compound could be used in the future to develop biotechnological products for the control of phytopathogenic fungi.
