Surgical classification of renal calculi
No full textA classification of renal calculi is presented. 'C' describes the morphology, size and topography of the stone in five descriptive categories; the letter 'P', 'S', 'M', 'I' indicate the pelvis, the superior, middle and inferior calices, respectively, and complete the topographic description. The letter 'E' stands for the excretory tract; the symbols + and - are added tho indicate the presence or absence of dilatation and the small letters e and i indicate the intra- and extrarenal position of the pelvis. 'R' points out the number of surgical recurrences. In conclusion, the letter 'P' indicates the functional status of the parenchyma, and the numbers 1, 2, 3 refer to a normally functioning kidney; moderate renal insuffiency, or serious renal insufficiency. 'U' symbolizes a solitary anatomical or functional kidney
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
Ecografia endocavitaria con microsonda rotante da 12.5Mhz : una nuova metodica di studio delle patologie dell'apparato urinario
No full textEndoluminal sonography performed with 12.5 MHz miniature transducer-containing catheters with diameter of 6 or 9 Fr., is a new technique for the study of urinary tract. We studied: U.S. scan of 10 corpes and 10 operatory specimens (bladders and kidneys) with anatomic measurement in vitro. U.S. scan of 20 patients "in vivo" with pathologies involving bladder and upper urinary tract. We studied the normal anatomy of bladder and ureter by U.S. and we detected the structures beyond the ureteral lumen as: vessels, lymph nodes, muscle. Our indications for the utility of this new U.S. technique are: Detection and staging of superficial T.C.C. of the bladder. Detection of dangerous vessels near the U.P.F before endopielotomy. Excretory tract minus (endoluminal ultrasound is helpful in differentiating such pelvic filling defects as blood clots, no opaque stones and transitional cell carcinoma)
The use of vesical irrigation system dual pump Endo FMS urology in the endoscopic therapy of the vesical neoplasms
No full textObjective: The objective of this study was to determine whether vesical irrigation during transurethral resection of bladder tumours (TURBT) with the dual pump system for the intracavitary irrigation Endo FMS Urology is more efficient than the standard gravity technique. Methods: One hundred patients suffering from vesical neoplasms underwent TURBT using the Endo FMS Urology (group A). They were compared to 100 patients previously (2002-2003) treated endoscopically for vesical tumours with the standard endovesical irrigation method (group B). Results: We demonstrad a reduction of the average time of resection of 10% in favour of patients of group A, a reduction of 39% of the amount of fluid of vesical irrigated in favour of patients of group A. No differences were observed in the recurrence rate of tumours at 3 months and in need of endoscopic revision in the 48 hours following TURBT. Two patients required blood transfusion after TURBT in group B, none in group A. The average time of hospitalisation in group A was less than one day. Conclusions: On the basis of this experience the use of Endo FMS Urology Irrigation System in TURBT is strongly recommended
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
