No full text[ES] Los objetivos de este TFG son el diseño de una explotación de engorde de aves para 18560 plazas en San Agustín, en el sur de la provincia de Teruel. El proyecto se hace teniendo en cuenta las reglamentaciones de producción ecológica. En el proyecto se incluyen cálculos de: instalaciones y equipos; eléctricos, hidráulicos, ventilación, sistemas de alimentación, calefacción, tratamiento de residuos e instalaciones para el control de vehículos y personas. El Proyecto dispone de los planos necesarios para la realización de la obra civil. Además, se realiza un estudio de seguridad y salud, presupuesto y pliego de condiciones. Se pretende diseñar y optimizar el manejo, instalaciones y alimentación para conseguir el máximo bienestar animal y producción de la forma más sostenible posible y con el menor impacto ambiental.[EN] The objectives of this TFG are designing a fattening farm for 18560 bird places in San Agustin, in the south of the province of Teruel. The project will take into account the regulations for organic production. Calculations in the project will include: facilities and equipment; electrical, plumbing, ventilation, feeding systems, heating, waste treatment facilities and control of vehicles and people. The project will have the plans necessary for the realization of civil works. In addition, a safety and health, budget and specifications will be made. It aims to design and optimize the management, facilities and food for maximum animal welfare and production of the most sustainable way possible and with the least environmental impact.Arlandis I Fonfria, V.

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
RF magnetron sputter deposition and characterization of Ca5(PO4)3OH-coatings

18560.pdf (Publisher’s version ) (Open Access)ABSTRACT Calcium phosphates, especially hydroxyapatite (HA), are preferred implant materials for implants used to replace bone tissue, like hip-implants, due to their excellent biological properties and bone bonding behaviour. To avoid its poor fatigue properties in loaded applications, HA is supplied as a coating on mechanical strong titanium implant materials. Since plasma spraying, which is nowadays the most widely used technique to apply such coatings, suffers some severe drawbacks, other techniques to apply thin, adherent, and dense coatings are investigated. The aim of this study was to explore the feasibility to apply thin adherent hydroxyapatite layers on titanium substrates by rf magnetron sputter deposition. Especially the effect of variation of different sputter parameters on the properties of the deposited films was investigated. For this purpose deposition power, argon pressure, oxygen pressure and water-vapour pressure was varied during deposition. The films were analysed with ion beam techniques like RBS, ERD, PIXE, XPS and Auger, and with XRD, FTIR, SEM and EDS. To measure the interface strength of the coatings a novel laser spallation technique was used. We were able to get an insight in the parameters which are important for the sputter process, and to obtain dense and thin coatings with a good stoichiometry and an excellent adhesion strength. The results of this research opens the way to the use of these sputter deposited HA coatings in clinical studies.Promotores : J. Jansen en F. Habraken120 p
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
