Vita nei lacioni e dintorni, 3
No full textL’indagine è stata condotta in vari biotopi astatici (lacioni) con raccolte faunistiche di elementi del plancton e del benthos, che hanno permesso di produrre un elenco faunistico non esaustivo. Una parte più dettagliata del monitoraggio, comprendente dati sia qualitativi sia quantitativi, è stata svolta sulla componente faunistica a crostacei entomostraci, permettendo di delinearne le dinamiche stagionali anche in connessione con le tipologie idrologiche dei diversi lacioni. Lo studio pone anche in relazione le caratteristiche pluviometriche medie della riserva con le differenti fasi di sviluppo della fauna acquatica di questa acque astatiche

Symptom and joint mobility progression in the joint hypermobility syndrome (Ehlers-Danlos syndrome, hypermobility type)
No full textObjective To evaluate progression of symptoms and joint mobility in the joint hypermobility syndrome (JHS) in order to identify specific disease pictures by age at presentation. Methods Fifty JHS patients (44 females, 6 males) were evaluated by Beighton score (BS) calculation, and presence/absence and age at onset of 20 key symptoms. Incidence and prevalence rates by age at onset and sex were calculated and compared by chi-square, Fisher's exact test and Mann-Whitney U-test. Relationship between BS and age at examination was evaluated by the Spearman rho correlation. The existence of an age cut-off separating patients with or without a positive BS was analysed by the receiver operating characteristic analysis. Influence of age on the single components of the BS was also investigated. Results Except for isolated features the overall clinical presentation was the same between sexes. In the whole sample, statistically significant differences by age at presentation were registered for fatigue, myalgias, muscle cramps, strains/sprains, dislocations, tendon ruptures, tendonitis, gastroesophageal reflux, chronic gastritis, constipation/diarrhoea and abdominal hernias. A clear inverse correlation between age at examination and BS was demonstrated with an age cut-off fixed at 33 years. Among the components of the BS, spine and elbow joints were not significantly influenced by age. Conclusions This study confirmed the existence of a protean clinical history of JHS which may be exemplified in. different phases with distinguishable presentations. The knowledge of the peculiarities of each of them will help the practitioner in recognising and, hopefully, treating this condition
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
I lacioni della Selva del Lamone, 2
No full textL’indagine presentata in questo volume riguarda le raccolte temporanee di acqua dette “lacioni” presenti nella Riserva Selva del Lamone. Prima di questa indagine era pressochè sconosciuta la dinamica di questi fragili ecosistemi e sulle specie animali e vegetali che li popolano. Lo studio è durato complessivamente da giugno 2007 a dicembre 2009, includendo la fase preliminare di sopralluoghi orientativi e gli ultimi mesi di campionamenti limitati alla sola fauna invertebrata. Grazie ai dati raccolti è stato possibile individuare e cartografare le superfici occupate dai lacioni; • determinare per alcuni lacioni le caratteristiche chimico-fisiche delle acque e le relazioni tra queste e i parametri pluviometrici; approfondire le conoscenze sulla fauna invertebrata e sugli anfibi; inquadrare la vegetazione sia fitosociologicamente sia in termini di habitat sensu Direttiva 92/43/CEE; determinare i fattori di minaccia per la conservazione dei biotopi stessi
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
Focal muscle vibration: evaluation of physical properties and his applications
No full textVibration is the sensation produced by sinusoidal oscillation of objects placed against the skin. The vibratory frequency is signaled by the frequency of action potentials fired by the sensory nerves and the total number of active sensory nerves is linearly related to the
amplitude of vibration. In the last years many works were done evaluating the different clinical applications of the focal muscle
vibration; the aim of this work is to analyze the interaction between the vibratory application and the skin. For this study the
apparatus of focal muscle vibration analyzed was firstly calibrated by measuring the actual peak to peak displacement of the tip as a
function of the power supplied to the shaker; then were measured the Direct Component (DC) of the force by which the shaker is
pushed against the patient’s skin and the Alternate Component (AC). We observed that from displacements imposed by the tip
ranging from 0 to about 200 micrometers, the applied load increases monotonically, but non linearly, with the displacement; above this value, any further increase of the peak to peak displacements actually does not lead to an effective increase of the amplitude of the mechanical stimulation. We can conclude that with this focal muscle vibration applied to the muscle we are able to stimulate the spindles that respond to 200 micrometers amplitude that are probably ones able to generate a proprioceptive signal
