L’allevamento bovino nella valle del Torto: un caso di zootecnia sostenibile in Sicilia

2011

In spite of not being the main activities of Sicilian agriculture, zootechny plays a very important social role, even more than economic, for a large part of Sicily. The crisis that has hit the industry since early 2000s, and particularly cattle livestock, caused the closure of many holdings and a strong decrease in the number of animals bred, both meat and dairy cattle. The beef cattle population in the Valle del Torto, in the province of Palermo (area covered by this study), for many decades has significantly contributed to the development of a rural community that trough this activity created his own wealth, income and economic stability. The crisis that over the last decade has affected…

Palmprint and face score level fusion: hardware implementation of a contactless small sample biometric system

2011

Including multiple sources of information in personal identity recognition and verification gives the opportunity to greatly improve performance. We propose a contactless biometric system that combines two modalities: palmprint and face. Hardware implementations are proposed on the Texas Instrument Digital Signal Processor and Xilinx Field-Programmable Gate Array (FPGA) platforms. The algorithmic chain consists of a preprocessing (which includes palm extraction from hand images), Gabor feature extraction, comparison by Hamming distance, and score fusion. Fusion possibilities are discussed and tested first using a bimodal database of 130 subjects that we designed (uB database), and then two …

Multidimensional shaping of spatiotemporal waves in multimode nonlinear fibers

2019

Recent experiments have shown that nonlinear wave propagation in multimode optical fibers leads to complex spatio-temporal phenomena. In this talk, we introduce new approaches for the control and optimization of nonlinear beam reshaping in the spatial, temporal and spectral dimensions. The first approach applies to spatial beam self-cleaning the technique of transverse wavefront shaping, which permits to launch an optimized input mode combination, that results in the stable generation of a whole nonlinear mode alphabet at the fiber output. The second approach introduces a longitudinal tapering of the core diameter of multimode active and passive fibers, which permits to generate ultra-wideb…

Kerr Beam Self-Cleaning in Multimode Fibers

2018

We overview recent experimental results of beam self-cleaning observed in various types of multimode fibers. We analyze the output spatial beam shapes and their connection with the refractive index profile of the fibers.

Modular Assembly of Multimodal Imaging Agents through an Inverse Electron Demand Diels–Alder Reaction

2019

International audience; The combination of two imaging probes on a same biomolecule gives access to targeted bimodal imaging agents that can provide more accurate diagnosis, complementary information, or that may be used in different applications, such as PET imaging and fluorescence imagingassisted surgery. In this study, we demonstrate that dichlorotetrazine, a small, commercially available compound, can be used as a modular platform to easily assemble various imaging probes. Doubly-labeled tetrazines can then be conjugated to a protein through a biorthogonal IEDDA reaction. A series of difunctionalized tetrazine compounds containing various chelating agents and fluorescent dyes was synth…

Marquage de molécules biologiques par des complexes de radiométaux à base de polyamines macrocycliques

2012

This work conducted at the “Institut de Chimie Moléculaire de l’Université de Bourgogne” carries at first on the synthesis of bifunctional chelating agents suitable for the chelation of trivalent radiometals, including indium-111. The greater part of this work was then dedicated to the grafting of a DOTA derivative bifunctional chelating agent on different antibodies or fragments of monoclonal antibodies: trastuzumab (anti-HER2 treatment of breast cancer), cetuximab (anti EGFR, treatment of many cancers, including colorectal cancer) and abciximab (antiplatelet). Particular attention was paid to the characterization of various immunoconjugates. The critical step of this thesis consisted in t…

Activité physique : Prévention et traitement des maladies chroniques

2019

Les maladies chroniques sont des affections non transmissibles de longue durée, parfois permanentes, qui évoluent avec le temps. Selon l’OMS, elles sont la première cause de mortalité mondiale et en Europe elles "concourent à près de 86% des décès […] et pèsent de plus en plus lourdement sur les systèmes de santé, le développement économique et le bien-être d’une grande partie de la population, en particulier chez les personnes âgées de 50 ans et plus".En France, la part des personnes âgées de 60 ans et plus devrait passer d’un quart en 2015 à un tiers de la population en 2040. Actuellement, c’est un français sur quatre qui souffre d’une maladie chronique, trois sur quatre après 65 ans. Ave…

Using cross-modal interactions to counterbalance salt reduction in solid foods

2011

International audience; We investigated odour-induced saltiness enhancement (OISE) in a solid model cheese with the aim of evaluating the influence of cross-modal interactions (odour-texture-taste) on saltiness perception and assessing the efficacy of using OISE to counterbalance salt reduction. Four model cheeses, varying in texture, were flavoured with three commercial tasteless aromas (comte cheese, sardine and carrot) differently associated with salty and cheesy food products. Twenty-seven consumers evaluated taste intensity, aroma intensity and its congruence with the product flavour, and the overall pleasantness of 12 flavoured and four unflavoured samples. The comparison of the perce…
