Durante este periodo aprendí diferentes técnicas y la utilización de distintos equipos que paso a detallar:
1. Técnicas y equipos
1.1. Medición de la presión arterial sistòlica de ratas:
Las ratas se colocan en una cámara a 37°C durante 10 minutos y después se transfieren a una cámara acrilica que contiene una almohadilla de calefacción. En este momento se coloca un manguito y un sensor de pulso en la cola del animal (Narco Biosystems, Houston, TX). El manguito está conectado a un cilindro de aire comprimido a través de una disposición de las válvulas de entrada y salida que permiten inflarlo y desinflarlo a una velocidad constante. La presión en el manguito se registra continuamente con un sensor de presión (Sensym, Honeywell Sensing & Control, Ine.). Las señales de los sensores de pulso y la presión se amplifican y digitalizan con un tablero analógico-digital (DT16EZ, Data Translation, Ine., Marlboro, MA). Los archivos para su posterior procesamiento son obtenidos con el software correspondiente (Labtech Notebook Pro, Laboratorio Technology Corp., Wilmington, MA). Para cada determinación se registran las lecturas, así como el intervalo de compresión. Además del aprendizaje de esta técnica aprendí el procesamiento de esta información y su posterior análisis.

A study of the electrical and charge-collection properties of semi-insulating GaAs detectors
No full textIn this work a numerical approach has been used to investigate some properties of semi-insulating GaAs detectors. In particular, the electric field and the carriers mean free path distributions have been obtained, by solving transport and Poisson equations. The knowledge of these quantities allows us to determine the charge-collection efficiency and other detector characteristics. A comparison with the experimental results of X-ray irradiated detectors of different thicknesses has been carried out. RI Cola, Adriano/G-2379-201
Variations on the Author
No full text“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
Frequency of musculoskeletal conditions among patients referred to Italian tertiary rheumatological centers
No full textThe characteristics of symptomatic osteoarthritis in general and specialist practice in Italy: design and methods of the AMICA Study
No full textOBJECTIVE: The diagnostic and clinical approach to osteoarthritis (OA) of the hand, knee, and hip in general practice and specialist practice in Italy as determined by the AMICA project.
METHODS: Eligible subjects were identified among patients aged > or =50 years consecutively observed by their general practitioner (GP) or a specialist during the study period for diagnosis or treatment of symptomatic OA of the hand, knee, or hip. OA was diagnosed according to the American College of Rheumatology clinical criteria. The general characteristics and symptoms of all eligible subjects were evaluated. Data were also collected on diagnostic work-up and treatment. All subjects were also asked to quantify the intensity of their OA-related pain according to a 100-mm visual analog scale (VAS) where 0 = no pain and 100 = the worst pain.
RESULTS: A total of 2764 GP and 331 specialists (98 rheumatologists, 166 orthopedic surgeons, and 67 other specialists) participated in the study. The area of residence was largely similar for both GPs and specialists and covered all of Italy. A total of 25,589 valuable subjects with OA were identified by the GPs, while 3543 were identified by the specialists. Among the latter, 1777 were identified by orthopedic surgeons, 1067 by rheumatologists, and 699 by other specialists (specialists in physical medicine and internal medicine, geriatricians, etc). The median age of patients identified by GPs was 70 years; the corresponding value was 66 years for the patients identified by the orthopedic surgeons, 69 years by the rheumatologists, and 68 years by other specialists. Overall, 69% of patients were women: this proportion was similar among patients identified by the GPs, the orthopedic surgeons, and other specialists, but patients identified by the rheumatologists were women in 80% of cases. Patients observed by the specialists had a higher level of education than those observed by GPs (P < 0.05). This finding was partially explained by the younger age of the patients observed by the specialists.
CONCLUSIONS: This large data set reveals the attitudes of Italian GPs and specialists toward the diagnosis and treatment of OA of the hand, knee, and hip
Biblioteche e AI Literacy: alcune riflessioni sulle nuove competenze per la mediazione informativa
No full textIl tradizionale ruolo di mediazione informativa svolto dai/dalle bibliotecari/bibliotecarie, si arricchisce oggi di nuovi
contenuti che riguardano la divulgazione della conoscenza sull’uso il più possibile esperto degli strumenti basati
sull’intelligenza artificiale generativa. Questa nuova tecnologia, infatti, lungi da escludere i mediatori informativi,
quali sono i/le bibliotecari/e, e aggravare definitivamente le conseguenze del fenomeno della disintermediazione,
che ha caratterizzato questi decenni e ha messo in crisi la professione bibliotecaria, soprattutto nelle aree STEM e
Bio-Medical, può rappresentare un elemento di “riscatto” nei termini dell’evoluzione della professione verso una
dimensione spiccatamente divulgativa. A nostro avviso non esiste, o quasi, categoria professionale più adatta a
sanare i grandi vuoti di competenza e di conoscenza di un fenomeno così complesso, ma nello stesso tempo così
pervasivo come la diffusione dei tools di intelligenza artificiale, soprattutto nell’ambito frequentato dai/lle bibliotecari/
e, cioè l’informazione. Pensiamo a quanto possa essere utile “guidare” i ricercatori attraverso strumenti
che permettano loro di affidare all’AI gli aspetti più compilativi della loro attività di studio e ricerca, e permettere
loro di concentrarsi solo sugli aspetti speculativi e creativi, anche grazie ai suggerimenti delle macchine intelligenti.
E questo facendo solo il nostro consueto lavoro di fact checking e di verifica delle fonti informative, indipendentemente
dal contesto bibliotecario in cui ci si trovi a operare, oltre che dei contenuti proposti dall’AI che
possono essere falsati da bias e/o allucinazioni (che comunque dipendono sempre dall’interazione con gli umani).
La conoscenza dei tools - di cui ragioniamo nell’ultima parte di questo lavoro per dare concretezza ad un tema che
altrimenti rischia di essere troppo astratto per le nostre comunità di riferimento - si affianca così alla tradizionale
information literacy, una competenza che si pratica nelle nostre biblioteche e che trova così nuovi spunti per
aggiornarsi e continuare ad essere di supporto alla crescita informativa e intellettuale dei nostri utenti, per una
partecipazione sempre più consapevole ed esperta alla vita del XXI secolo

L’obiettivo del paper è offrire strumenti per migliorare l'alfabetizzazione informativa mediatica, proponendo strategie innovative, collaborazione proattiva per l'inclusività e l'impegno critico nell'era digitale
Exploring Emptiness: An Investigation of MA and MU in My Sonic Composition Practice
No full textThe commentary investigates Japanese aesthetics of space, silence and emptiness - ma and mu - that informed my compositional practice during the research period 2012 - 2015. The portfolio comprises text compositions and sound installations in which forms of micro events and sustained events are employed. Throughout, the emphasis is on my personal engagement with, and manifestation of emptiness that concerns a particular model of listening and perception.
Chapter 1 discusses six primary research areas: ma and mu, material, text, form, listening and perception. Firstly, I introduce ma and mu by examining noh culture and Zeami's teaching of senu hima (where there is no-action) in the context of my personal approaches to music. The following subjects are then used to contextualise my PhD practice by means of examples from various composers and visual artists. Here, these particular and enigmatic concepts are explored through Japanese art as well as Western contemporary works by Alvin Lucier, Eliane Radigue and those of the Wandelweiser collective.
Part 2 provides contextual commentaries on selected compositions from the portfolio that mostly articulate my aesthetics in relation to the topics covered in Chapter 1. koso koso addresses my methodologies to investigate the essence of senu hima, followed by treow that discusses my approach to materials and the importance of space. I move on to grade two and grade two extended in order to examine text scores, and then, look into Espèces d'espaces 03 and 04 as examples of musical forms that I employ.
Finally, listening and perception are investigated through the compositions gnome and con.de.structuring. Throughout, I describe how my works explore emptiness as a result of my particular emphasis on listening over composing
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
