Assessment of new soft cane varieties
No full textIn 2016, three new cane varieties, SRA1, SRA4 and QC04-1411, were either released or were proposed for release into the Bundaberg and Mackay districts. According to the pre-release fibre quality measurements undertaken by Sugar Research Australia, all three varieties were classified as a soft cane. This report documents a series of experiments undertaken to better define soft canes and to measure the effect that these three varieties had on factory operation and performance. \ud
The experiments were undertaken collaboratively by QUT, SRA and field and factory staff in the Isis, Farleigh, Millaquin and Maryborough districts.\ud
Trash has been shown to affect the fibre quality measurements, reducing the short fibre content by typically 12 units and most likely increasing the shear strength measurement by about 6 units. Comparing the cleaned stalks of cane usually used for fibre quality measurements to factory-prepared cane, it seems likely that shear strength is underestimated by about 7 units and short fibre content is underestimated by about 4 units (most likely shredder dependent).\ud
SRA1 had a low fibre content of typically 10% and an impact resistance lower than the minimum criterion considered for normal canes. The other two varieties, SRA4 and QC04-1411 had relatively normal fibre content of about 14%. While their impact resistance was low, it was still within the normal range. Shear strength is the other fibre quality parameter with a defined normal range. The shear strength of all three varieties were within the normal range, with SRA1 having the lowest values. The final fibre quality parameter, short fibre content, does not have a defined normal range. It is noted, however, that of the 35 results examined, the two highest values were for QC04-1411 and the next two highest values were for SRA1 (Q240 was the fifth highest and also had a shear strength lower than QC04-1411).\ud
The low fibre content of SRA1 is considered the biggest problem regarding the processing of the three varieties. With current major varieties having fibre contents of typically 12% to 15%, SRA1 is particularly different and will cause fuel balance issues. The fact it is different to the other varieties means that it is difficult to configure a factory to consistently achieve a fuel balance, with the likelihood that there will be periods when fuel will need to be purchased and other periods when fuel will need to be disposed of. The fact it is low means that a factory will need to be reconfigured at high capital cost to become much more energy efficient.\ud
All three varieties exhibited the soft cane characteristic of generating low mill torques. While there is some hope that mills could be re-set to achieve their torque set point when processing soft cane, the wide variation in variety characteristics between the soft canes and the other varieties in the cane supply means that a much wider control range is required to be able to achieve their torque set points across the different varieties.\ud
Associated with the inability to maintain torque set points, bagasse moisture contents from the soft canes were found to be higher than normal. This result was particularly pronounced with SRA1 where Isis and Millaquin recorded increases in final bagasse moisture content of between three and eight units. The available information from the processing of SRA4 and QC04-1411 also showed higher bagasse moisture content but the results are less conclusive, due to the limited nature of the trials of those varieties. Not all factory boilers can withstand significant increases in bagasse moisture content. The Millaquin experience processing SRA1 resulted in a rapid drop in steam pressure that only avoided a boiler shutdown because SRA1 was only processed for 15 minutes. Sustained factory operation when feeding boilers with high moisture bagasse is problematic.\ud
There was a potential concern with the processing of QC04-1411 where the bagasse caused feeding and combustion issues. It is unknown if this problem is characteristic of the variety or simply a one-off incident.\ud
Other problems such as poor mill feeding and frothing when processing the soft cane varieties were experienced but are believed to be able to be resolved with relatively small capital expenditure.\ud
While the yield of some of the soft cane supplies was measured to be quite high, those yield benefits need to be weighed up against the additional factory processing costs that will be incurred in terms of capital upgrades and stops
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.
