New advances in the pharmacological treatment of HIV
No full textThe availability of new advances in the pharmacological management of HIV has made HIV a chronic and medically manageable condition. With improving access and availability of HIV drugs, the life expectancy of HIV patients has increased. Despite the success of antiretroviral therapy in reducing viral loads and improving patient health, it has not been possible to cure an individual of HIV infection in order to induce permanent remission in the absence of therapy. For years now, great research efforts have been made to understand the exact mechanism of HIV persistence and to develop therapies or prevention methods to eliminate or permanently suppress HIV strands in people. The effects of a cure would substantially benefit the individual, resolving the need for lifelong daily therapy and also benefit the society by reducing the costs of treatment and the rate of HIV transmission.The availability of combination antiretroviral therapy for prevention as well as treatment and other prevention methods suggests that HIV infection can be controlled with available breakthrough medications from appropriate research.általános orvosmagyaregységes, osztatla
Kinetic Potentials of the Effect of Ethanol on Calcium Content of Ashed Palm Bunch (Elaeis guinensis)
Get PDFThe effect of ethanol on the calcium content of ashed palm bunch (Elaeis guineensis) was studied. The palm bunch residue was subjected to pre-treatment processes such as drying, grinding and ashing. The calcium content of the filtered extract of the ash was determined titrimetrically and a concentration of 73.33 mg/l of calcium was recorded. Kinetic studies were carried out on the mixture of local ethanol and the ash extract and the effect of ethanol on calcium concentration was monitored using titrimetric method at 10 minutes interval. The ethanol led to a gradual decrease in the concentration of calcium with increase in time, the rate constant value was 0.67 mgdm3min-1 and half life of 54.97 minutes. Analysis of the kinetic data showed that the reaction was zeroth order as it fitted into the zeroth order integrated rate law. The average pH of the reaction mixture was alkaline (10.57
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
