A method for the territorial organization of socio-sanitary services
1983
The need for a profound change in the health service has recently led to the development of a national sanitary plan, which the Italian government has submitted to the political and social forces as a midterm strategy for the transformation of the health service.
Assessment of the pedicel detaching and crashing forces of grape berries to determine the right mechanical harvesting period
2007
During the mechanical harvesting the shakers cause the detachment of the grape berries from the grape stalk but also the breaking of the grape berries peel with the consequent production of must that influences the quality of the harvested grapes. This one is higher in the varieties having grape berries more resistant to the crushing and, at the same time, an easier detachment of the pedicel. The aim of this work is to evaluate, for three different varieties of grape (Chardonnay, Catarratto comune and Nero d’Avola), the crushing strength of the berry, that represents the cause of the production of must during the mechanical harvesting, and the resistance of the berry-pedicel system that inf…
Curved Edge Routing
2001
We consider the problem of drawing a graph where edges are represented by smooth curves between the associated nodes. Previously curved edges were drawn as splines defined by carefully calculated control points. We present a completely different approach where finding an edge is reduced to solving a differential equation. This approach allows to represent the graph drawing aesthetics directly, even the most complex ones denoting the dependencies among the paths.
Application of graphene quantum dots in heavy metals and pesticides detection
2020
Graphene Quantum Dots (GQDs) were produced using electrochemical oxidation of graphite rods. Obtained GQDs were gamma-irradiated in the presence of the N atoms source, ethylenediamine. Both structural and morphological changes were investigated using UV-Vis, X-ray photoelectron and photoluminescence (PL) spectroscopy as well as atomic force microscopy. The ability of both types of dots to change PL intensity in the presence of pesticides such as malathion and glyphosate, as well as copper (II) ions was detected. These preliminary results indicated a high potential of produced GQDs to be applied as non-enzymatic PL sensors for the detection of selected pesticides and metal ions. 26th Interna…
Electrical magnitudes in gravitational and centrifugal systems
1993
Abstract A new formulation to study the non-equilibrium processes in gravitational and centrifugal electrochemical systems is developed. The driving forces and the fluxes are measurable quantities. The electrical equilibrium and the pure electrical conduction are described in an evident, simple and exact manner. Theoretical expressions of the emf for several gravitational cells are shown. Some differences are observed with those given in the literature ( eg the terminals density does not appear). The electrochemical potential of ion species is the basic piece in this study.
Tidal gravity observations at Mt. Etna and Stromboli: Results concerning the modeled and observed tidal factors
2009
Continuous gravity observations performed in the last few years, both at Mt. Etna and Stromboli, have prompted the need to improve the tidal analysis in order to acquire the best corrected data for the detection of volcano related signals. On Mt. Etna, the sites are very close to each other and the expected tidal factor differences are negligible. It is thus useful to unify the tidal analysis results of the different data sets in a unique tidal model. This tidal model, which can be independently confirmed by a modeling of the tidal parameters based on the elastic response of the Earth to tidal forces and the computation of the ocean tides effects on gravity, is very useful for the precise t…
Grip Force Adjustments Reflect Prediction of Dynamic Consequences in Varying Gravitoinertial Fields
2018
International audience; Humans have a remarkable ability to adjust the way they manipulate tools through a genuine regulation of grip force according to the task. However, rapid changes in the dynamical context may challenge this skill, as shown in many experimental approaches. Most experiments adopt perturbation paradigms that affect only one sensory modality. We hypothesize that very fast adaptation can occur if coherent information from multiple sensory modalities is provided to the central nervous system. Here, we test whether participants can switch between different and never experienced dynamical environments induced by centrifugation of the body. Seven participants lifted an object …
Spatules de Thierry ou forceps : comparaison des morbidités materno-fœtales
2016
Resume Objectif Comparer la morbidite materno-fœtale immediate lors d’une l’extraction par forceps ou par spatules de Thierry. Methodes Etude retrospective, descriptive, monocentrique de 2006 a 2012. Les extractions etaient realisees par spatules ou forceps pour defaut de progression du mobile fœtale, sur singleton, en presentation cephalique, a terme, sans anomalies du rythme cardiaque fœtal et sans pathologie gravidique associee. Resultats Notre serie comprenait 65 extractions par spatules contre 77 par forceps. Nos populations etaient comparables. Au niveau maternel, on retrouvait davantage de perinees intacts (5,19 % versus 15,38 %, p = 0,04), autant de dechirures vaginales et moins de …
Investigations of Surface Forces between Gypsum Microcrystals in Air Using Atomic Force Microscopy
2000
This article introduces a new approach to the study of the interactions between gypsum faces in air. We have mounted a gypsum crystal on the end of a microcantilever to measure local forces (van der Waals, capillary forces, electrostatic) directly between two crystals. A systematic study with respect to the orientation of crystalline faces, relative humidity, and the duration of contact between crystals improves the understanding of the mechanism involved in the hardening of plaster in air. In dry air, a physicochemical process of matter transfer is added to the van der Waals forces to ensure the cohesion. Others force measurements were performed by varying the shape of the contact (interac…
