Le due crisi: crisi del capitalismo e crisi ambientale. Una soluzione sostenibile?
2015
Le due crisi in titolo sono due facce di una stessa medaglia; e il tema verrà trattato su questa rivista in due parti divise solo al fine di agevolare la lettura. Nella Parte I si evidenzia come la crisi ambientale derivi dal generale rapporto di predazione e spoliazione delle risorse naturali, caratteristico del modo capitalistico di produzione e consumo; ancor più devastante nella sua attuale fase “iperliberista”. I danni sociali della crisi economica sono drammaticamente evidenti alla maggior parte dell’opinione pubblica – la critica alle attuali teorie e modelli economici sarà oggetto della Parte II – mentre le altrettanto drammatiche conseguenze della crisi ambientale faticano a diveni…
Proteomic analysis highlights the role of detoxification pathways in increased tolerance to Huanglongbing disease.
2016
Background Huanglongbing (HLB) disease is still the greatest threat to citriculture worldwide. Although there is not any resistance source in the Citrus germplasm, a certain level of moderated tolerance is present. A large-scale analysis of proteomic responses of Citrus may help: 1) clarifying physiological and molecular effects of disease progression, 2) validating previous data at transcriptomic level, and 3) identifying biomarkers for development of early diagnostics, short-term therapeutics and long-term genetic resistance. Results In this work we have conducted a proteomic analysis of mature leaves of two Citrus genotypes with well-known differing tolerances to HLB: Navel orange (highl…
Peri-implant parameters in head and neck reconstruction: influence of extraoral skin or intraoral mucosa.
2009
Objective: This study is designed to assess dental implants supporting overdentures in edentulous patients with operated head and neck malignancies using parameters to detect peri-implant disease. Material and methods: Thirty-four implants supporting overdentures in 34 oral cancer patients were examined. Clinical parameters [plaque index, probing depth, bleeding on probing (BOP), origin of peri-implant soft tissue, and amount of irradiation] were recorded, and microbiological identification of periodontal pathogens was carried out by DNA–DNA hybridization. To identify yeast species, the samples were cultivated on Sabouraud agar plates and subsequently identified by API 20C AUX plates. An im…
The 15 March 2007 explosive crisis at Stromboli Volcano, Italy: assessing physical parameters through a multidisciplinary approach
2011
Basaltic volcanoes are dominated by lava emission and mild explosive activity. Nevertheless, many basaltic systems exhibit, from time to time, poorly documented and little-understood violent explosions. A short-lived, multiblast explosive crisis (paroxysmal explosion) occurred on 15 March 2007 during an effusive eruptive crisis at Stromboli (Italy). The explosive crisis, which started at 20:38:14 UT, had a total duration of ∼5 min. The combined use of multiparametric data collected by the permanent instrumental networks (seismic, acoustic, and thermal records) and a field survey carried out immediately after the event enabled us to constrain the eruptive dynamics and quantify physical param…
Italian guidelines on management of persons with multimorbidity and polypharmacy
2022
AbstractMultimorbidity and polypharmacy are emerging health priorities and the care of persons with these conditions is complex and challenging. The aim of the present guidelines is to develop recommendations for the clinical management of persons with multimorbidity and/or polypharmacy and to provide evidence-based guidance to improve their quality of care. The recommendations have been produced in keeping with the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Overall, 14 recommendations were issued, focusing on 4 thematic areas: (1.) General Principles; (2.) target population for an individualized approach to care; (3.) individualized care of patients with mul…
Highly angular resolving beam separator based on total internal reflection
2019
We present an optical element for the separation of superimposed beams that only differ in angle. The beams are angularly resolved and separated by total internal reflection at an air gap between two prisms. As a showcase application, we demonstrate the separation of superimposed beams of different diffraction orders directly behind acousto-optic modulators for an operating wavelength of 800 nm. The wavelength as well as the component size can easily be adapted to meet the requirements of a wide variety of applications. The presented optical element allows one to reduce the lengths of beam paths and thus to decrease laser system size and complexity.
Dimensioni di personalità in soggetti obesi BED e NON-BED.
2012
Introduzione Pochi studi hanno esaminato la presenza di differenti dimensioni di personalità in soggetti obesi BED e non-BED (Peterson et al., 2010) e i risultati appaiono ancora poco chiari. Lo studio si propone di: a) confrontare le dimensioni di personalità in soggetti obesi BED e non-BED; b) approfondire l’associazione tra stili di personalità e comportamenti binge in relazione ad altre variabili sintomatiche. Metodo 143 soggetti adulti obesi non-BED e 60 soggetti obesi BED che hanno richiesto un trattamento presso un sevizio pubblico sui disturbi alimentari, hanno compilato i seguenti strumenti di assessment: MCMI-III (Millon, 1997), BES (Gormally et al, 1982), OQ-45 (Lambert et al., 2…
A formal proof of the ε-optimality of absorbing continuous pursuit algorithms using the theory of regular functions
2014
Published version of an article from the journal: Applied Intelligence. Also available on Springerlink: http://dx.doi.org/10.1007/s10489-014-0541-1 The most difficult part in the design and analysis of Learning Automata (LA) consists of the formal proofs of their convergence accuracies. The mathematical techniques used for the different families (Fixed Structure, Variable Structure, Discretized etc.) are quite distinct. Among the families of LA, Estimator Algorithms (EAs) are certainly the fastest, and within this family, the set of Pursuit algorithms have been considered to be the pioneering schemes. Informally, if the environment is stationary, their ε-optimality is defined as their abili…
Die Primärstabilität von manuell und roboterassistiert implantierten Hüftendoprothesenstielen: eine biomechanische Untersuchung an Kunstfemora
2004
AIM We investigated the initial stability of cementless stems implanted with robotic milling and conventional manual broaching. METHODS Proximally porous structured stems (G2, ESKA-Implants, Luebeck, Germany) were implanted into synthetic femora. In one group, the femoral cavity was prepared by a CT-based robot (CASPAR, URS-Ortho, Germany) with a high-speed milling head. In the other group, femora were rasped manually with broaches. The broaches had 1 mm proximal press-fit, the robotic cavities 1.5 mm. The implants were exposed to 15 000 loading cycles with 1 000 +/- 500 N. The direction of forces on the implant head were chosen to simulate stair climbing. Internal rotation and translation …
Uso degli inibitori di pompa protonica in un Policlinico Universitario
2012
Summary Introduction Proton pump inhibitors (PPIs) are highly prescribed drugs in Italy and in particular in the Sicilian region but little is known about their use in the hospital setting. Materials and methods PPI utilization and related costs were reviewed retrospectively by examining the pharmaceutical records of drug dispensation to the various wards of the Policlinico Universitario P. Giaccone of Palermo in 2010. Differences in the prescribing rates and drug preferences among the different clinical wards were analyzed. Results A total of 20,420 patients were hospitalized at the Policlinico of Palermo in 2010. Overall, the consumption of PPIs was 120 DDD/100 bed-days for the year 2010 …
