Performance of coated soybean seeds with different sources and doses of phosphorus
No full textAs limita????es na disponibilidade de f??sforo no in??cio do ciclo vegetativo podem resultar em restri????es no desenvolvimento, condi????o da qual a planta n??o se recupera posteriormente, mesmo sendo aumentado o suprimento de f??sforo a n??veis
adequados. O presente trabalho teve como objetivo verificar o efeito de diferentes fontes e dosagens de f??sforo no crescimento e produtividade de plantas de soja,
provenientes de sementes tratadas pelo processo de recobrimento. Foram realizados dois experimentos. O primeiro envolveu dois n??veis de fertilidade do solo: 1) solo adubado conforme recomenda????o da pesquisa para a cultura da soja (SN) e; 2) solo com a aduba????o tr??s vezes superior a recomendada pela pesquisa (SA). Foram utilizadas as seguintes fontes de f??sforo para o tratamento das sementes:
fitina, fosfato bic??lcico, fosfato natural daoui, superfosfato triplo e fosfato monoam??nico, sendo cinco dosagens: 0; 2; 4; 6 e 8g por 100g de sementes, de cada fonte. As avalia????es realizadas foram: emerg??ncia, ??rea foliar e mat??ria seca
da parte a??rea aos 25 dias ap??s a emerg??ncia. No segundo experimento, foi utilizado somente um n??vel de fertilidade do solo, com aduba????o conforme a recomenda????o da pesquisa. Foram utilizadas as seguintes fontes de f??sforo para o
tratamento das sementes: fitina, fosfato monoc??lcico, fosfato de pot??ssio e fosfato de s??dio, sendo cinco dosagens de cada fonte: 0; 0,9; 1,8; 2,7 e 3,6g por 100g de sementes. As avalia????es realizadas foram: emerg??ncia; ??rea foliar e mat??ria seca da parte a??rea aos 25 e 50 dias ap??s a emerg??ncia; n??mero de sementes por planta; peso de mil sementes e produtividade por planta. O delineamento estat??stico
utilizado foi o de blocos casualizados, com tr??s repeti????es. Os resultados permitiram concluir que: 1) a fitina e o fosfato monoc??lcico, aumentam a produtividade da cultura da soja em n??vel superior a 15%; 2) o recobrimento de sementes de soja com f??sforo, provenientes de fitina e fosfato monoc??lcico, promove o aumento da ??rea foliar e mat??ria seca das plantas de soja; 3) a emerg??ncia das plantas de soja ?? afetada negativamente, quando se utiliza fosfato de s??dio, superfostato triplo ou fosfato monoam??nico no tratamento das sementes.The limitations on the availability of phosphorus in the early growing season could result in restrictions on development, a condition in which the plant does not recover afterwards, even though increasing the supply of phosphorus at
appropriate levels. This study aimed to determine the effect of different sources and levels of phosphorus on growth and productivity of soybean plants, grown from seeds treated by the coating process. Two experiments were conducted. The first involved two levels of soil fertility: 1) soil fertilized according to recommendations of the survey for the soybean crop and 2) soil with fertilizer three times higher than that
recommended by the survey. It was used the following sources of phosphorus in the treatment of seeds: phytin, dicalcium phosphate, natural daoui phosphate, triple
superphosphate and monoammonium phosphate, and five doses: 0, 2, 4, 6 and 8g per 100g of seeds from each source. The evaluations were: emergence, leaf area and shoot dry matter at 25 days after emergence. In the second experiment, it was used only one type of soil, with fertilizer as recommended by the research. It was used the following sources of phosphorus in the treatment of seeds: phytin, calcium phosphate, potassium phosphate and sodium phosphate, five doses of each source: 0, 0.9, 1.8, 2.7 and 3.6 g per 100g of seeds. The evaluations were: emergence, leaf
area and shoot dry matter at 25 and 50 days after emergence, number of seeds per plant, thousand seed weight and productivity per plant. The statistical design was a
randomized block design with three replications. The results allowed to conclude that: 1) phytin and the monocalcium phosphate, increase the productivity of soybean in the 15% level; 2) the coating of soybean seeds with phosphorus from phytin and monocalcium phosphate, promotes increased leaf area and dry weight of soybean plants; 3) the emergence of the soybean plants is adversely affected when using sodium phosphate,Triple superphosphate or monoammonium phosphate in the treatment of seeds
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
