Restoration of Facial Defects with Digital Technology
No full textThis book takes a step-by-step approach to the resolution of complex facial prosthetic rehabilitations with digital itechnology.
Key features:
• includes coverage of case studies of facial disfiguring due to cancer or trauma using both surgical and prosthetic process
• describes the step-by-step protocol to digitally design ear, oculofacial and nasal prostheses, and to mold manufacturing using modern 3D printing technology
• provide evidence-based state-of-the-art protocol on maxillofacial and craniofacial implant surgery related to the facial rehabilitation
“Restoration of facial defects with digital technology” gives global descriptions of each method so that readers can project, design, and manufacture and maxillofacial prosthesis and customize maxillo facial surgery. It also covers using CAD-CAM technology to reduce the cost and time of making a facial prosthesis. The complete workflow for producing the ear, nasal, and oculofacial prosthesis (implant and mechanically supported) and for oncological maxillo facial surgery is described. The atlas form of the book describes each procedure in a stand-by-step manner so that readers may reproduce the process and obtain improved results will respect to the analogic procedures. This book communicates the most update knowledge and the method of digital technology applied to the maxillofacial rehabilitation workflow, in a way that all may use it as a guide for replication the methodologies presented in this book. This book will help also informatics technicians and biomedical engineers to project and customize the virtual construction of the prosthesis. It also describes how to use the new technology to reduce time and cost of the operatory room. The information in this book will also led readers:
• know the new methodologies to use digital technology instead of analogic procedures by anaplastologists;
• accomplish unusual hygiene procedures of craniofacial implants (Hygienist) ;
• propose prosthetic alternative solution instead of the plastic surgery to the patient who lost ear, nose or facial parts for oncologic or traumatic reasons;
• simplify the plastic reconstructive surgery and the module as a function of the final prosthetic rehabilitation supported by craniofacial implants.
The book has been written by exports in the field, pulling together information from disparate sources into one reference, making it Ideal for anyone working in maxillofacial rehabilitation of the face
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
Hormonal control of subcutaneous adipose tissue aquaglyceroporins
No full textGlycerol metabolism in normal condition and in metabolic disorders like type-2 diabetes and obesity could depend at least in part on the transmembrane transport mechanisms of glycerol. Aquaglyceroporins (AQPs) are integral membrane protein belonging to the water channel proteins family (aquaporins) that are permeable to glycerol as well as water. Adipose tissue, the main source of plasma glycerol, expresses high levels of AQP7 but also AQP3, 9, 10. Recently, in adipose tissue was also found AQP11, whose permeability to glycerol is uncertain. However, the hormonal regulation of AQPs in the adipose tissue is not completely characterized. To this purpose we evaluated the effect of insulin, isoproterenol, thyroxin, dexamethasone in human isolated adipose tissue by real time RT-PCR. Immunocytochemistry was also performed to define the localization of the AQPs. Results showed that all the AQPs investigated are expressed in the human subcutaneous adipose tissue with a localization of AQP3,7 and 10 in both plasma membranes and in lipid droplets membranes, AQP9 mainly in the plasma membrane and AQP11 in the lipid droplets membrane. Generally, lipolytic and lipogenic stimuli differently affected the AQPs expression which depicts a complex situation involving, probably, different signaling pathway. These results and other recently described by the literature seem support the existence of different AQPs that under hormonal control and in pathological conditions can modify their expression levels and cellular localization, suggesting them as potential therapeutic targets in obesity and metabolic syndrome
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
