STUDI TEKNIS SISTEM PENYALIRAN TAMBANG UNTUK PENAMBANGAN BATUBARA PT. BHARINTO EKATAMA DI KABUPATEN KUTAI BARAT PROVINSI KALIMANTAN TIMUR
Get PDFPT. Bharinto Ekatama is a coal mining company which is located approximately
100 km to the north of the Melak city and 160 km towards the northwest of Balikpapan in
East Kalimantan. PT. Bharinto Ekatama located in the Coal Mining Cooperation Agreement
with an area of 22,000 ha. Mining system that is used is the open pit system which is
dependent upon the weather, especially the rain. Rainwater that enters the mine area will
greatly affect the production of coal.
PT. Bharinto Ekatama has two pit mining pits are the pits 3000 and 6000 are located in
Biangan. Mining in pit 3000 and pit 6000 until mid-2013 was estimated at -55 m elevation
above sea level. The main problem at the PT. Bharinto Ekatama pit is the mine water. Mine
sequence’s cause mine drainage system has to change. Hence the need for technical studies
on existing mine drainage system. From the measurement results obtained total catchment
from January to June of 11.02 km2 with the highest rainfall in the month of December 2011 is
875 mm and the lowest rainfall in August 2006 was 14 mm. To prevent water from entering
into the mining sites used open channel located in the north of the pit 6000. The open channel
has a top width (6m - 7m), bottom width (2m - 3m), with depths ranging between (3m - 4m).
Open channel to drain the water from the wells (sump) in the pits 6000 and 3000 towards a
settling pond has a top width (2m - 4m), bottom width (1m - 2m) and depth ranges
(2m - 3m ). Wells on the location of the research serves to hold water so as not to
commemorate the pit floor. In pit 3000 the surface width and length dimensions of the
surface 53 m, width and length of the base wells 49 m with a depth of 3m. In pit 6000 the
with a depth of 4 m, width and surface wells 75m length, width and length of 70m wells
basis. The water in the sump will be pumped and discharged into settling ponds.
Water must be moved using the pump, the pump used in study sites are centrifugal
pumps Multiflo Pump (MFV 390) 1 unit in pit 3000, and MFV 420E 1 unit in pit 6000. Of
each sump, water will be pumped to the settling ponds where the total head to be overcome
of pit 3000 by 55 m, and from the sump pit 6000 total head of 65 m. The Settling pond
currently has 3 compartments. For SP-BK02-01 with a total volume of 15.260 m3, solid
dredging done during settling ponds have been filled range as much as 72% - 74% of the
volume on each compartment, while the settling ponds BK02-SP-02 has a total volume
42.542 m3, conducted dredging if the settling ponds have filled 70% - 72% of the volume of
each compartment
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.
