Net charge and polarizability of zeolitic Brønsted acidic sites
The interacting induced-dipoles polarization model, implemented in our program POLAR, is used for the calculation of the effective polarizability of the zeolitic bridged OH group, which results much higher than that of the free silanol group. A high polarizability is also calculated for the bridged OH group with a Si4+, in the absence of Lewis-acid promotion of silanol by Al3+. The crystal polarizability is estimated from the Clausius-Mossotti relationship. Siliceous zeolites are low-permittivity isolators. The interaction of a weak base with the zeolitic OH can be considered as a local bond. Only when cations are located in the zeolite micropore, next to tetrahedra that contain trivalent c…
Contributo alla conoscenza floristica dei monti Sicani (Sicilia): resoconto dell’escursione del Gruppo di Floristica (S.B.I.) nel 2012
The results of the excursion of the “Gruppo di Floristica” of the Italian Botanical Society held in the Sicani Mountains (CW-Sicily) on May 3-6, 2012, are here presented. During the research a total of 532 taxa was recorded. Three of them, the native Rosa squarrosa and the alien Phyllostachys aurea and Vitis ×koberi are new to Sicily, and 14 are new to the Sicani Mts. On the other side, we confirm the exclusion of Erica manipuliflora from the flora of the region.
Guidance to 2018 good practice: ARIA digitally-enabled, integrated, person-centred care for rhinitis and asthma
AIMS: Mobile Airways Sentinel NetworK (MASK) belongs to the Fondation Partenariale MACVIA-LR of Montpellier, France and aims to provide an active and healthy life to rhinitis sufferers and to those with asthma multimorbidity across the life cycle, whatever their gender or socio-economic status, in order to reduce health and social inequities incurred by the disease and to improve the digital transformation of health and care. The ultimate goal is to change the management strategy in chronic diseases. METHODS: MASK implements ICT technologies for individualized and predictive medicine to develop novel care pathways by a multi-disciplinary group centred around the patients. STAKEHOLDERS: Incl…
Allergic Rhinitis and its Impact on Asthma (ARIA) Phase 4 (2018): Change management in allergic rhinitis and asthma multimorbidity using mobile technology
Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second c…
Effect of Packing on Cluster Solvation of Nanotubes
It is discussed the possibility of the existence of single-wall carbon nanotubes (SWNTs) in organic solvents in the form of clusters, containing a number of SWNTs. A theory is developed based on a bundlet model for clusters, which enables describing the distribution function of clusters by size. Comparison of the calculated values of solubility with experimental data would permit obtaining energetic parameters characterizing the interaction of an SWNT with its surrounding, in a solid phase or solution. Fullerenes—SWNTs are unique objects, whose behaviour in many physical situations is characterized by remarkable peculiarities. Peculiarities in solutions show up first in that fullerenes—SWNT…
