Musica, architettura e arti figurative nella Palermo di Giacomo Amato

Il contributo ripercorre le occasioni d'incontro tra la musica, l'architettura e le arti figurative negli anni in cui l'architetto Giacomo Amato fu attivo a Palermo, dal ritorno da Roma nel 1684 al 1732, data della sua morte. Si discute l'attività di Amato in due specifici campi connessi alla musica: da una parte scenografie e costumi per rappresentazioni legate alla committenza vicereale; dall'altra apparati per celebrazioni religiose non liturgiche quali le Quarant'ore o il Corpus Domini. Il suo apporto viene considerato in raffronto con la produzione simile di altri centri italiani, nel quadro della vita musicale dell'epoca.

Precession shift in curvature based extended theories of gravity and quintessence fields

AbstractIn this paper we constrain the sizes of hypothetical new weak forces by making use the data coming from the precession of Planets. We consider the weak field approximation of Scalar–Tensor Fourth Order Gravity (STFOG), which include several models of modified gravity. The form of the corrections to the Newtonian potential if of the form of Yukawa-like potential (5th force), i.e. $$V(r)=\alpha \frac{e^{-\beta r}}{r}$$ V ( r ) = α e - β r r , where $$\alpha $$ α is the parameter related to the strength of the potential, and $$\beta $$ β to the range of the force. The present data on periastron advance allow to infer a constraint on the free parameter of the gravitational models. Moreo…

Epidemiology and Microbiology of Skin and Soft Tissue Infections: Preliminary Results of a National Registry

Skin and soft tissue infections (SSTIs) represent a wide range of clinical conditions characterized by a considerable variety of clinical presentations and severity. Their aetiology can also vary, with numerous possible causative pathogens. While other authors previously published analyses on several types of SSTI and on restricted types of patients, we conducted a large nationwide surveillance programme on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients. Twenty-five Infectious Diseases (ID) Centres throu…
