Chemical Composition and Biological Activities of Prangos ferulacea Essential Oils
2022
Prangos ferulacea (L.) Lindl, which belongs to the Apiaceae family, is a species that mainly grows in the eastern Mediterranean region and in western Asia. It has been largely used in traditional medicine in several countries and it has been shown to possess several interesting biological properties. With the aim to provide new insights into the phytochemistry and pharmacology of this species, the essential oils of flowers and leaves from a local accession that grows in Sicily (Italy) and has not yet been previously studied were investigated. The chemical composition of both oils, obtained by hydrodistillation from the leaves and flowers, was evaluated by GC-MS. This analysis allowed us to …

The Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties
2017
A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 +/- 120 years), the Arctic shark Somniosus microcephalus. Three major hemoglobins are found in its red blood cells and are made of two copies of the same a globin combined with two copies of three very similar beta subunits. The three hemoglobins show very similar oxygenation and carbonylation properties, which are unaffected by urea, a very important compound in marine elasmobranch physiology.…
Entanglement entropy in a periodically driven quantum Ising chain
2016
We numerically study the dynamics of entanglement entropy, induced by an oscillating time periodic driving of the transverse field, h(t), of a one-dimensional quantum Ising chain. We consider several realizations of h(t), and we find a number of results in analogy with entanglement entropy dynamics induced by a sudden quantum quench. After short-time relaxation, the dynamics of entanglement entropy synchronises with h(t), displaying an oscillatory behaviour at the frequency of the driving. Synchronisation in the dynamics of entanglement entropy, is spoiled by the appearance of quasi-revivals which fade out in the thermodynamic limit, and which we interpret using a quasi-particle picture ada…
Work fluctuations in bosonic Josephson junctions
2016
We calculate the first two moments and full probability distribution of the work performed on a system of bosonic particles in a two-mode Bose-Hubbard Hamiltonian when the self-interaction term is varied instantaneously or with a finite-time ramp. In the instantaneous case, we show how the irreversible work scales differently depending on whether the system is driven to the Josephson or Fock regime of the bosonic Josephson junction. In the finite-time case, we use optimal control techniques to substantially decrease the irreversible work to negligible values. Our analysis can be implemented in present-day experiments with ultracold atoms and we show how to relate the work statistics to that…
Association between clusters of diseases and polypharmacy in hospitalized elderly patients: results from the REPOSI study.
2011
BACKGROUND: Although the association between multimorbidity and polypharmacy has been clearly documented, no study has analyzed whether or not specific combinations of diseases influence the prescription of polypharmacy in older persons. We assessed which clusters of diseases are associated with polypharmacy in acute-care elderly in-patients. METHODS: This cross-sectional study was held in 38 Italian internal medicine and geriatric wards participating in the Registro Politerapie SIMI (REPOSI) study during 2008. The study sample included 1155 in-patients aged 65 years or older. Clusters of diseases, defined as two or more co-occurring specific chronic diseases, were identified using the odds…
MoMo: enabling hybrid museums
2005
Present-day museums are not mere passive institutions for the preservation of a society's cultural heritage. They have become instead learning environments, research centres and even tourist attractions. The paper introduces the notion of a hybrid museum (HM) in which wireless personal digital devices (PDAs) are used to tailor digital contents to the visitor to enrich both the learning and entertainment experience. The paper describes a fully functional hybrid museum infrastructure (MoMo) implemented with the.NET compact framework running on the PocketPC platform. Several research challenges that had to be faced during the implementation of the system such as the exploration of large sets o…
Datu Modeļa Izstrādes Optimizācija
2017
Projekta "Datu Modeļa Izstrādes Optimizācija" mērķis ir optimizēt esošo datu modeļa pārvaldes risinājumu. Projekta galvenais mērķis ir palielināt sistēmas izmantošanas ērtumu. Turklāt, projekta sekundārais mērķis ir samazināt datnes izmēru diskā un uzlabot darbības ātrumu. Šie mērķi tika sasniegti, izmantojot šādus soļus: •XML datņu struktūra tiek mainīta, datnes lasāmības uzlabošanai; •Neizmantoti un novecojuši dati tiek izņemti no datu kopām; •Ieviests rīks, ar kura palīdzību var pārveidot datus jaunajā struktūrā; •Integrēta spēja lasīt, rediģēt un saglabāt jauno struktūru, esošajā tīmekļa lietojumprogrammā.
Motivations, engagement and adoption of e-WOM in restaurants.
2022
Resumen El objetivo del presente trabajo fue estudiar el efecto que tienen las motivaciones para consultar y escribir e-WOM sobre el compromiso con el e-WOM y la influencia de dicho compromiso en la adopción del e-WOM consultado. Para analizar estas relaciones, se realizó una investigación empírica aplicada en el contexto de los restaurantes. El ámbito geográfico fue Ecuador, con una muestra de 461 consumidores. Se utilizó un modelo de ecuaciones estructurales y se validó la cadena de relaciones. Los resultados confirmaron las relaciones entre estas variables; además, se presentaron implicaciones académicas interesantes para profundizar en el estudio sobre el compromiso con el e-WOM, así co…
