Effects of Exercise on the Airways
2012
In the last ten years, the effects of exercise on bronchial epithelial cells and inflammatory cells in the airways have been studied in detail, and such new information has been combined with previous knowledge on bronchial reactivity and asthma evoked by exercise in asthmatic patients and athletes. The resulting picture is very complex, and the potential clinical consequences are often contradictory, suggesting the opportunity to define different phenotypes of exercise-associated airway changes (Lee & Anderson, 1985; Haahtela et al., 2008; Moreira et al., 2011a). Studies in asthmatic athletes in the 90’ had began to explore the possibility that airway inflammation might be involved in exer…
Teatral'nost' v tvorčestve O. I. Senkovskogo
2001
The present study is dedicated to O. I. Senkovsky, (1800-1858) who was a professor of St. Petersburg University, an outstanding scientist, editor-in-chief of a popular magazine “Reading Library”, an influential literary critic, and a writer. This study provides a novel perspective on Senkovsky’s legacy, an attempt to comprehend his works through theatrical methods.Senkovsky’s literary masks express theatricality in his works. The name of his most famous pseudonym Baron Brambeus borrows deliberately from the Russian “lubok” literature in order to attract the attention of a general reader. It is Senkovsky’s bent for exotics, parody and paradox as the methods for his work that has defined the …
An integrated fuzzy-stochastic model for revenue management: The hospitality industry case
2016
Revenue management aims at improving the performance of an organization by selling the right product/service to the right customer at the right time. This task is very dependent on uncontrollable external factors. In the hospitality industry, rooms of the hotel represent perishable assets and fixed capacities at the same time. Therefore, in the case of a stochastic process for customers calling in reservations prior to a particular booking date, a common problem for hotels is to devise a policy for maximizing the total expected profit conditional on the set of bookings. We propose a fuzzy model for the hotel revenue management under an uncertain and vague environment. Fuzziness of objectiv…
LINEAMENTI DI ENTOMOLOGIA IN AGRICOLTURA BIOLOGICA
2018
Il libro di testo Lineamenti di Entomologia in Agricoltura Biologica vuole essere un sussidio, un filo conduttore, nell’introduzione allo studio dell’entomologia agraria, con un occhio di riguardo alle problematiche riscontrabili nelle produzioni in regime di agricoltura biologica. Il testo, infatti, presenta le caratteristiche per fornire un valido supporto didattico agli studenti iscritti ai corsi di studio delle lauree in Scienze e Tecnologie Agrarie, Agroalimentari e Forestali, che affrontano insegnamenti di entomologia agraria. Non di meno, l’attenzione posta ad approfondire aspetti relativi ai mezzi e ai metodi di controllo può renderlo uno strumento valido anche per gli studenti che …
Efficacia delle reti protettive, del rotenone e dello spinosad nel controllo di Ceratitis capitata (Wiedemann) su pesco biologico
2009
In the organic farming the control of Ceratitis capitata (Wiedemann) is problematic for late ripening peach cultivars. In 2007 and 2008 we tested a protective net, rotenone and spinosad in a biodynamic peach orchard in Castrofilippo (AG). Traps baited with Trimedlure were placed in July and observed weekly. In 2007 there were 3 plots: rotenone, net cover and untreated. In 2008 a thesis with spinosad was added. Since the beginning of August four rotenone and spinosad treatments were done weekly. The net plot was covered since the end of July. At the commercial harvesting sampling on peaches were done collecting and analysing 50 peaches for each thesis, recording infested fruits. First male c…
Leisure-time physical activity for health promotion in elderly: initial evidence from the ‘‘Passiata Day’’ model
2018
Purpose: Falls prevention interventions are a priority for public health systems in order to reduce falls-related high costs. The University Hospital of Palermo promoted the ‘‘Passiata Day’’ model, an initiative of the Department of Geriatrics that provided a 1-h walk for once a week in a park of Palermo. It was guided by a graduate in physical education and a medical doctor. The aim of this study was to evaluate posturographic parameters in a sample of elderly including a group of subjects that had been walking regularly in the ‘‘Passiata Day’’ model for 6 months and a group of sedentary elderly subjects. Methods: A number of 109 older people were recruited at the University Hospital of Pa…

VALUTAZIONE DELLA DENSITÀ OSSEA DI UN CAMPIONE DI SOGGETTI PARAPLEGICI. RUOLO DEL DOTTORE IN SCIENZE MOTORIE NEL RECUPERO DELL’AUTONOMIA MOTORIA.
2008
Scopo del lavoro è stato quello di valutare in pazienti maschi paraplegici gli adattamenti del tessuto osseo del rachide in toto e dei vari segmenti scheletrici in conseguenza della prolungata immobilità e di proporre dei nuovi protocolli d’attività motoria che possano sia limitare il decadimento progressivo delle strutture osteo-articolari, sia di preparare i pazienti all’ utilizzo di nuove tecnologie che consentano una pur parziale autonomia motoria. Allo studio hanno partecipato volontariamente venticinque soggetti paraplegici di sesso maschile con lesioni complete T3- L3, suddivisi in due gruppi in relazione agli anni di lesione: il primo gruppo è composto da 13 soggetti con lesione mid…
Anatomia clinica del sistema articolare del piede
2006
From a semantic point of view the word “ankle” and “ankle region” are not synonyms as “ankle” identifies all the components of the ankle joint while “ankle region” identifies the ankle joint as well as every structures in the region, form the surface level to the skeletal one. The articular system of the foot is formed by thirthyfour synovial joints, seventeen of which have complementary curvilinear articular surface, the remaning seventeen having plane joints. The rounded surface joints are: the talonavicular joint (a spheroidal joint that is part of the transverse tarsal joint), the “anatomical” subtalar joint ( a saddle joint), five ellipsoid (or condylar) joints and ten, ankle and inter…
A Simple Noise Model with Memory for Biological Systems
2005
A noise source model, consisting of a pulse sequence at random times with memory, is presented. By varying the memory we can obtain variable randomness of the stochastic process. The delay time between pulses, i. e. the noise memory, produces different kinds of correlated noise ranging from white noise, without delay, to quasi-periodical process, with delay close to the average period of the pulses. The spectral density is calculated. This type of noise could be useful to describe physical and biological systems where some delay is present. In particular it could be useful in population dynamics. A simple dynamical model for epidemiological infection with this noise source is presented. We …
