Brasília, 2011.O tanino condensado (TC) no valor nutritivo de forragens temperadas e na saúde dos ruminantes em concentrações moderadas pode ser utilizado para promover aumento da eficiência da digestão da proteína e melhoria das condições sanitárias do rebanho, influenciando positivamente a qualidade da carne. Objetivou-se avaliar a interferência do TC presente no Sansão do Campo utilizado na dieta de cordeiros sobre as características quantitativas e qualitativas da carcaça e sua ação anti-helmíntica sobre T. colubriformis. Foram utilizados 24 cordeiros machos inteiros da raça Santa Inês com peso vivo (PV) 26,89±2,16kg criados em sistema de confinamento total desde o nascimento e mantidos em baias individuais por 10 semanas. Foi coletado dado do peso médio inicial e final, ganho total (GT), ganho médio diário (GMD), peso metabólico (PM), consumo em relação ao PV, consumo de matéria seca (MS), consumo de MS por unidade de PM e conversão alimentar. O delineamento experimental foi inteiramente casualizado com arranjo fatorial (2X2) com quatro tratamentos, com dois tipos de dietas com e sem Polietilenoglicol (PEG) e animais sadios e infectados. Análises foram feitas através do teste de médias (Tukey 5%) do programa estatístico SAS. Após o jejum e dieta hídrica, os animais foram abatidos e as carcaças permaneceram em câmara fria por um período de 24h. Foram coletados os dados referentes às características quantitativas e qualitativas da carcaça, dos componentes corporais e cortes comerciais. Realizada a leitura do pH inicial e final e avaliações subjetivas da distribuição de gordura na carcaça. Retiradas as frações da região da 11 a 13a costelas da carcaça esquerda para análise de área de olho de lombo, composição tecidual e centesimal, avaliação dos parâmetros físico-químicos e composição de ácidos graxos (AG). Houve diferença significativa (p<0,05) com valor superior da contagem de ovos por grama de fezes (OPG) para o tratamento Sansão+Infecção+PEG e um menor grau de infecção para o tratamento Sansão+Infecção. Para GMD e GT foi verificado que o tratamento Sansão+Infecção (116,0g e 7,5kg) apresentou valores inferiores aos tratamentos Sansão+PEG (150,7g e 9,8kg) e Sansão+PEG+Infecção (152,9g e 9,9kg) demonstrando redução do desempenho desses animais, mas não havendo diferença significativa entre o tratamento Sansão (142,5g e 9,2kg). Foi observada diferença significativa (p<0,05) para perímetro e o peso dos testículos, sendo que as maiores médias foram no tratamento Sansão+PEG (24,62cm e 0,40kg) quando comparada com as médias obtidas nos tratamentos Sansão+Infecção+PEG (22,00cm e 0,28kg), Sansão (21,00cm e 0,25kg) e Sansão+Infecção (22,23cm e 0,28kg). Características quantitativas, cortes comerciais, composição tecidual e centesimal, avaliação dos parâmetros físico-químicos apresentaram similaridade nos tratamentos. A dieta que contem TC presente no Sansão do Campo é recomendada por apresentar um desempenho semelhante nos animais sadios e infectados por desencadear uma redução do OPG de T. colubriformis em ovinos infectados, além de influenciar o perfil de AG saturados, mono e poli-insaturados. O ácido graxo oleico foi que mais contribuiu para a composição total dos ácidos graxos monoinsaturados e o ácido graxo araquidônico nos ácidos graxos poli-insaturados. _______________________________________________________________________________________ ABSTRACTThe condensed tannin (CT) in temperate forage nutritive value and health of ruminants in moderate concentrations can be used to promote increased efficiency of protein digestion and health conditions of the herd, positively influencing the quality of meat. The objective was to evaluate the interference of CT present in the Sansão do Campo in the diet of lambs on the quantitative and qualitative carcass and its anthelmintic action on T. colubriformis. We used 24 male lambs entire Santa Ines weight (BW) 26.89 ± 2.16 kg raised in total confinement system from birth and kept in individual stalls for 10 weeks. We collected data of initial and final weight, total gain (TG), average daily gain (ADG), metabolic weight (MW), PV in relation to consumption, consumption of dry matter (DM), DM intake per unit of PM and feed conversion. The experimental design was completely randomized design with factorial arrangement (2x2) with four treatments, with two types of diets with and without polyethylene glycol (PEG) healthy and infected animals. Analyses were performed using the test of means (Tukey 5%) of the SAS statistical program. After fasting and water diet, the animals were slaughtered and the carcasses remained in cold storage for a period of 24 hours. We collected data on quantitative and qualitative characteristics of the carcass, body components and the commercial cuts. Performed the reading of the initial and final pH and subjective evaluations of the distribution of fat in the carcass. Withdrawals from the region of fractions 11 to 13th ribs of the carcass left for the analysis of loin eye area, and proximate tissue composition, evaluation of physical and chemical parameters and composition of fatty acids (FA). There was a significant difference (p<0.05) with higher value of egg counts per gram of feces (EPG) for treating infection Sanson+Infection + PEG and a lower degree of infection to treat Infection+Sanson for ADG and TG were found that treatment Sanson+Infection (116.0 g and 7.5 kg) were lower than the Sanson+PEG treatment (150.7 g and 9.8 kg) and Sanson+PEG+Infection (152.9 g and 9.9kg) demonstrating reduced performance of these animals, but no significant difference between treatment Sanson (142.5 g and 9.2 kg). It thas no significant difference (p<0.05) for perimeter and the weight of the testes, and the averages were higher in the treatment Sanson+PEG (24.62 cm and 0.40 kg) compared with the averages of the Sanson+Infection+PEG treatment (22.00 cm and 0.28 kg), Sanson (21.00 cm and 0.25 kg) and Sanson+Infection (22.23 cm and 0.28 kg). Quantitative traits, commercial cuts, and proximate tissue composition, evaluation of physical and chemical parameters had similar treatments. The diet containing Sanson CT present in the field is recommended to present a similar performance in healthy and infected animals by triggering a reduction of the parasite EPG T. colubriformis in sheep infected, and influence the profile of fatty acids, saturated, monounsaturated and polyunsaturated. The fatty acid was oleic contributor to the overall composition of fatty acids and monounsaturated arachidonic in fatty acids polyunsaturated.Faculdade de Agronomia e Medicina Veterinária (FAV)Programa de Pós-Graduação em Ciências Animai
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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.
