Three-Dimensional Surface Display in Blood Pool Gated SPECT
1994
In 14 patients (4 in good health and 10 with coronary heart disease) a blood pool gated single photon emission computed tomography (SPECT) was executed. The transaxial slices of the cardiac blood pool were reconstructed. A three-dimensional surface display was employed for the analysis of the tomographic data. A fixed distance, a fixed threshold (50%), and some different planes of view were employed. The test permitted visualiza tion of the ventricular and the atrial movements in all patients. The right ventricle was clearly seen in the right anterior oblique plane of view. The aortic beating was seen. In normal patients the left ventricle, clearly seen in left anterior oblique plane, shra…
Carbon stock increases up to old growth forest along a secondary succession in Mediterranean island ecosystems.
2019
The occurrence of old-growth forests is quite limited in Mediterranean islands, which have been subject to particularly pronounced human impacts. Little is known about the carbon stocks of such peculiar ecosystems compared with different stages of secondary succession. We investigated the carbon variation in aboveground woody biomass, in litter and soil, and the nitrogen variation in litter and soil, in a 100 years long secondary succession in Mediterranean ecosystems. A vineyard, three stages of plant succession (high maquis, maquis-forest, and forest-maquis), and an old growth forest were compared. Soil samples at two soil depths (0-15 and 15-30 cm), and two litter types, relatively undec…
Extended Pancreas Donor Program—The EXPAND Study
2018
BackgroundPancreas transplantation is the only curative treatment option for patients with juvenile diabetes. Organ shortage and restrictive allocation criteria are the main reasons for increasing waitlists, leading to severe morbidity and mortality. We designed a study to increase the donor pool wi
Application of microsatellite markers as potential tools for traceability of Girgentana goat breed dairy products
2015
In livestock, breed assignment may play a key role in the certification of products linked to specific breeds. Traceability of farm animals and authentication of their products can contribute to improve breed profitability and sustainability of animal productions with significant impact on the rural economy of particular geographic areas and on breed and biodiversity conservation. With the goal of developing a breed genetic traceability system for Girgentana dairy products, the aim of this study was to identify specific microsatellite markers able to discriminate among the most important Sicilian dairy goat breeds, in order to detect possible adulteration in Girgentana dairy products. A tot…
Characterizing weld pool surfaces from polarization state of thermal emissions
2013
International audience; In this Letter, a vision-based remote sensing methodology is proposed to measure the topography of weld pool surfaces from one single view. Thermal radiations emitted by the hot liquid metal at a wavelength within the arc plasma blind spectral window are acquired by a wavefront division polarimetric system. The refractive index of the liquid metal and the topography of the weld pool surface are inferred from the polarimetric state of the thermal radiations.

Designing ‘trait-based null model’ approaches to investigate community assembly mechanisms
2014
SPEEAECOLDURGEAPSIéquipe CAPA; During the last decade, many studies have addressed the signature of community assembly processes by assessing the deviation of a functional diversity pattern from that expected in null communities, using a randomization algorithm. The basic principle has been to compare the functional structure of a ‘local community’ with a set of randomly generated communities from a ‘regional species pool’. Specifically, it allows assessing the extent to which species constituting a community are functionally more or less similar than expected under the assumption of a random assembly, thus revealing the influence of assembly processes such as competition or environmental a…
Les espaces funéraires laténien et augusto-tibérien des Reliades (Le Puy-en-Velay, Haute-Loire).
2022
Le site des Reliades au Puy-en-Velay (Haute-Loire) a livré deux petits espaces funéraires à crémation utilisés entre La Tène finale et l’époque augusto-tibérienne. Caractérisés par une implantation sur un lieu à la topographie remarquable, ils ont fait l’objet d’aménagements paysagers qui viennent souligner leur caractère ostentatoire. Par ailleurs, la présence de bassins pose la question de l’utilisation de l’eau dans le cadre de cérémonies funéraires et/ou commémoratives. Enfin, bien que le mobilier déposé dans les sépultures soit peu abondant et très détérioré par son passage sur le bûcher, quelques éléments permettent d’attribuer aux défunts un statut social relativement élevé. Il s’agi…
The Influence of Behavioral Factors on Insurance Decision – A Romanian Approach
2013
Abstract Although the classical economic theory postulates that individuals should make perfectly rational choices that take into account all the available information, I will present, in the following, the action of behavioral factors on the decisions regarding the insurance against certain events. I will analyze the elements that determine a person who should be covered against a risk, not to buy insurance and the reverse situation when, although the likelihood of the event is reduced, a person will secure against the damage(s) caused by it. In this paper I developed a general approach of the behavioral factors with specific reference to the Romanian market .Finally, I will suggest the in…
Sporotrichoid Cases of Mycobacterium Marinum Skin Infection.
2010
Mycobacterium marinum belongs to the slow growth photochromogenous mycobacteria group. It is pathogenic for fish and human beings in which it can cause cutaneous nodular and ulcerative lesions, sometimes with sporotrichoid arrangement. We report three cases of sporotrichoid Mycobacterium marinum infections successfully treated with prolonged antibiotic therapy. Tropical fish aquaria and, more in general, the water environment were identified as the source of infection.
