Suppressiveness of 18 composts against 7 pathosystems : variability in pathogen response

2006

International audience; Compost is often reported as a substrate that is able to suppress soilborne plant pathogens, but suppression varies according to the type of compost and pathosystem. Reports often deal with a single pathogen while in reality crops are attacked by multiple plant pathogens. The goal of the present study was to evaluate the disease suppression ability of a wide range of composts for a range of plant pathogens. This study was conducted by a consortium of researchers from several European countries. Composts originated from different countries and source materials including green and yard waste, straw, bark, biowaste and municipal sewage. Suppressiveness of compost-amende…

Influence of Joint Geometry on Micro and Macro Mechanical Properties of Friction Stir Spot Welded Joints

2014

AbstractSpot welding can be considered a very common joining technique in automotive and transportation industries as it permits to obtain effective lap-joints with short process times and what is more it is easily developed through robots and automated systems. Recently, Friction Stir Spot Welding (FSSW) has been proposed as a natural evolution of the already known Friction Stir Welding (FSW) process, allowing to obtain sound spot joints that do not suffer from the insurgence of typical welding defects due to the melting of the base material. Similarly to FSW, both geometrical and technological parameters must be considered as they affect the material flow and the heat flux generated durin…

Towards Tool Path Numerical Simulation in Modified Friction Stir Spot Welding Processes

2009

Spot welding can be considered a very common joining technique in automotive and transportation industries as it permits to obtain effective lap-joints with short process times and what is more it is easily developed through robots and automated systems. Recently the Friction Stir Spot Welding (FSSW) process has been proposed as a natural evolution of the already known Friction Stir Welding (FSW) process, allowing to obtain sound spot joints that do not suffer from the insurgence of typical welding defects due to the fusion of the base material. In the paper, a modified Friction Stir Spot Welding (FSSW) process, with a spiral circular movement given to the tool after the sinking stage, is p…

Imbalanced Job Polarization and Skills Mismatch in Europe

2016

Abstract This paper considers the education of the labour force based on an analysis of trends in and the relationships between job polarization and skills mismatch. Both job polarization and skills mismatch have become topics of increasing interest, but relationships between the two have been relatively neglected in the literature. We argue that the relationship between polarization and skills mismatch is an empirical matter, which we analyse at both the macroeconomic and microeconomic level in European countries. A novel job polarization index (JPI) is proposed to measure imbalanced job polarization. It takes into account not only the change in the share of medium-level jobs, as is typica…

Study of periodic Dielectric Frequency-Selective Surfaces under 3D plane wave incidence

2016

A periodic Dielectric Frequency-Selective Surface (DFSS) is studied under 3D plane-wave incidence, whose unit cell in the periodic direction is composed of a dielectric grating and a homogeneous dielectric layer. The structure is excited by a linearly polarized plane-wave. The procedure for computing the Brillouin diagram of the structure under 2D plane-wave incidence with TE or TM polarization was already described by the authors, and the extension to the 3D incidence case has been performed in a similar way. Following the same formalism, it has been obtained the Generalized Scattering Matrix (GSM) of one period of the infinite periodic lattice. This requires the knowledge of the modal spe…

Un caso di disfonia severa provocata da una lesione monolaterale iatrogena del nervo laringeo ricorrente Considerazioni medicolegali

2013

di un intervento di emitiroidectomia, a causa di una lesione del nervo laringeo ricorrente di sinistra, riferibile ad una condotta colposa del chirurgo. Vengono considerati i risvolti medicolegali, porgendo particolare attenzione alla questione relativa al risarcimento cui l’operatore sanitario è obbligato, nei confronti del soggetto danneggiato. Tale compenso è stabilito in rapporto alla menomazione della funzione fonatoria subita dalla persona lesa e, pertanto, si riferisce non solo all’alterazione dell’integrità psicofisica e alle eventuali ripercussioni esistenziali che una tale condizione può determinare sulla qualità della vita, ma finanche alle conseguenze economicamente valutabili d…
