No full textYÖK Tez No: 382220Bu çalışmada Gümüşhane İl merkezindeki yerüstü sularının fiziksel jeokimyasal özeliklerinin belirlenmesi ve yan kayaç türü ile ilişkisinin incelemesi amaçlanmıştır. İnceleme alanından alınan su örneklerinin pH değerleri 6.3-8.2 ve iletkenliği 240-900 µS arasında değişmekte olduğu belirlenmiş olup, ayrıca bu değerler Türkiye ve WHO içme suyu standartlarına uygun olduğu da anlaşılmıştır. Çalışma alanındaki su örneklerinin sertliği 18.1-115.1 ºFr arasında olup oldukça sert-sert-çok sert su olarak sınıflandırılmıştır. Ayrıca su örnekleri Kıta İçi Su Kaynakları Kalite Kriterleri'ne göre değerlendirildiğinde, bazı parametreler bakımından (pH, Na, SO42-, Fe, Mn, Al, Co, Ni, Cu ve Cr miktarlarına göre) I. sınıf (yüksek kaliteli), bazı parametrelere (Cl- ve iletkenlik miktarlarına) göre I. ve II. sınıf (az kirlenmiş) sular sınıfında yer almaktadır. Pb konsantrasyonlarına göre bir kaç örnek hariç (SK-5, SD-1, OD-1 VE OD-19 nolu su örnekleri) I. ve II. sınıf sular, Zn içeriklerine göre bir kaç örnek (OD-10, OD-11, Ç-3, Ç-5, OD-9, OD-3-1 ve SK6-1 nolu su örnekleri) hariç I. ve II. sınıf sular, Cd miktarlarına göre bazı su örnekleri (Ç-6, OD-12, OD-8, Ç-8, OD-4-1, OD-3-1, Ç-1, OD-9, Ç-5, Ç-3, OD-11 ve OD-10 nolu su örnekleri) hariç I. ve II. sınıf sular olarak sınıflandırılmıştır. İnceleme alanındaki sular genel olarak karbonatlı ve sülfatlı (Ca+Mg>Na+K) sular sınıfında olup, genellikle zayıf asit kökleri güçlü asit köklerinden (HCO3-+CO32- > Cl-+SO42-) daha fazladır. İnceleme alanındaki suların pH'sı ile sularda değişik konsantrasyonlarda bulunan metaller arasında pek bir ilişki olmadığına kanaat getirilmiştir. Suların çıktığı yerlerde su-kayaç etkileşimi ile Fe, Ni, Cd, Pb, Zn ve Cu gibi elementlerin sularda zenginleştiği, maden atıklarının veya endüstriyel atıkların sulara karışması ile bu elementlerin sularda artış gösterdiği değerlendirilmiştir. Sonuç olarak bazı su örneklerinin içme ve kullanma suyu açısından iyi sular sınıfında olduğu belirlenmiştir. Anahtar Kelimeler: Fiziksel ve Kimyasal Parametreler, Gümüşhane, İçme Suyu, Su KalitesiIt has been aimed to determine the physical and geochemical properties of the existing surface waters at the study area covering the Gümüşhane city center and the investigation of the wall rock-water interaction. The pH of the water samples taken from the study area was 6.3-8.2 and their conductivity ranged between 240-900 µS and this was concordant to Turkey and WHO drinking water standards. Hardness of the water samples in the study area was between 18.1-115.1 oFr and was classified as extremely hard-hard-very hard water. In addition, when evaluated according to the Criteria for the Inland Surface Water Classification with respect to certain parameters (according to the amount of pH, Na, SO42-, Fe, Mn, Al, Co, Ni, Cu and Cr) was located in the I. class (high quality) water class, according to some parameters (according to the amount of the Cl- and conductivity) was located in the 1st and 2nd class (slightly polluted) water class. According to the Pb concentrations except by a few samples (SK-5, SD-1, OD-1 and OD-19 numbered water samples) was classified as I. and II. class water, according to the Zn contents except by a few samples (OD-10, OD-11, Ç-3, Ç-5, OD-9, OD-3-1 and SK6-1 numbered water samples) was classified as 1st and 2nd class water, according to the amount of Cd except by a few samples (Ç-6, OD-12, OD-8, Ç-8, OD-4-1, OD-3-1, Ç-1, OD-9, Ç-5, Ç-3, OD-11 and OD-10 numbered water samples) was classified as I. and II. class water. Waters in the study area in general was from carbonated and sulfated (Ca+Mg>Na+K) water classes and usually, their poor acids are more than their strong acids (HCO3-+CO32- > Cl-+SO42-). The pH (6.3-8.2) of the water in the study area showed no relationship between the metals present with varying concentrations in water. It is tought that elements like Fe, Ni, Cd, Pb, Zn and Cu are enriched in the waters with the water-rock interaction in the area where water rises or by the mixture of waters with mine waste or the industrial waste these elements were thought to increase. Also, it was determined that some water samples were determined to be in the good water class in terms of drinking and usage waters.

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.
