Postoperative analgesia in rhino surgery: An effective regimen with tramadol plus acetaminophen
No full textAim. The aim of this study was to assess the level of pain in patients undergoing to septo- and septorhinoplasty in order to develop an adequate protocol with tramadol plus acetaminophen. Methods. A group of 295 patients underwent septoplasty (group 1) and septorhinoplasty (group 2). In order to evaluate pain a visual analogical scale was used (VAS) 0, 4,12, 20 h postoperatively. The analgesic protocol began 10 minutes before the end of surgical procedure, and provided the infusion of acetaminophen (1 g) plus tramadol (1.5 mg/kg). Thirty minutes after surgery patients were treated with tramadol (200 mg) plus metoclopramide (10 mg in 500 mL of electrolytic solution) at 63 mL/h in continuous intravenous infusion. Paracetamol 1 g i.v. at 400 mL/h was administered after 8 hours, at the end of the first drug infusion. If VAS was equal or higher than 3 a rescue dose tramadol 50 mg plus metoclopramide 10 mg in 100 mL of NaCl 0.9% at 400 mL/h was administered. At day one intravenous therapy was stopped and replaced with oral administration of acetaminophen, 500 mg twice a day. Results. A good control of postoperative pain was obtained in 96.8% (group 1) and 81.4% (group 2) of the patients 4 hours after surgery. No significant differences were found with regard to pain scores and side effects. Conclusion. A protocol with tramadol and acetaminophen is extremely efficacious in the treatment of postoperative pain in the septo- and septorhinoplasty patients, with low rate of side effects
Solid state MPD thruster with applied magnetic field
No full textA solid state MPD thruster with applied magnetic field has been investigated. The MPDhas been operated with applied fields up to 0.4 T. Current, impulse bit and ablated masshave been measured. The thruster has shown a threshold value of the applied magnetic fieldover which it does not work, this threshold value increases with the shot energy. Away fromthis threshold value the current shows small variation with the applied field. The measuredvalues of the impulse bit are in accordance with the trends shown by previous investigationsand show a satisfactory agreement with the theoretical values calculated with one of theauthors’ theory
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
Digestibility, palatability and emotional status after ingestion of an iced dessert: analysis of subjective responses in 100 healthy volunteers.
No full textFood choices are influenced by many factors, perhaps the most important being availability. However, the desire to consume one item over another may be viewed as an outcome of sensory hedonic likes, situation and current internal state. In a previous preliminary report, an improvement of joy and mood, associated with good data of digestibility and palatability, was observed in a group of 30 healthy female subjects who consumed a coffee-flavoured iced dessert immediately after a standardized meal. The aim of this study is to confirm the results previously obtained in a smaller population and to investigate whether any differences between male and female subjects could be observed concerning the digestive process and emotional status. One hundred volunteers, after ENT and psychological assessment, were asked to fill out a Psycho-Emotional Questionnaire to assess their basal emotional pattern before the consumption of an iced coffee-flavoured dessert after a standard meal. After the meal they completed an Organoleptic-Sensory questionnaire, a Dynamic Digestibility questionnaire and again the Psycho-Emotional Questionnaire. In our study, most of the 100 subjects found the tested coffee-flavoured iced dessert pleasant according to the Organoleptic-Sensorial Questionnaire (OSQ), in terms of taste, aspect, texture and smell; moreover, the Dynamic Digestibility Questionnaire (DDQ) showed a good digestive experience in 71 subjects. According to the Psycho-Emotional Questionnaire (PEQ), an improvement of joy, activation and mood, associated with good data of digestibility and palatability was recorded. All these observations are statistically significant and the results seem to show a positive correlation between pleasure in eating such a product and emotional status. No statistically significant differences were recorded between male and female subjects
