Intergovernmental Grants as Signals and the Alignment Effect: Theory and Evidence
Chapter 3: MHD stability, operational limits and disruptions
Progress in the area of MHD stability and disruptions, since the publication of the 1999 ITER Physics Basis document (1999 Nucl. Fusion 39 2137-2664), is reviewed. Recent theoretical and experimental…

The discovery of Xylella fastidiosa from olive trees with “Olive quick decline syndrome” in October 2013 on the west coast of the Salento Peninsula prompted an immediate search for insect vectors of the bacterium, and transmission tests showed P. spumarius as a vector of X. fastidioa strain infecting olives trees in theSalento Peninsula, Italy.
ISOLATION OF A XYLELLA FASTIDIOSA STRAIN INFECTING OLIVE AND OLEANDER IN APULIA, ITALY
The isolation in pure culture of the Xylella fastidiosa strain associated with the quick decline syndrome of olive was attempted from symptomatic, naturally infected olive and oleander plants, and a periwinkle seedling that had been exposed to, and was infected by Xyleella-positive spittlebugs.
Model for the sawtooth period and amplitude
A model for sawtooth oscillations in tokamak experiments is outlined. A threshold criterion for the onset of internal kink modes and a prescription for the relaxed profiles immediately after the…
Economic and Social Consequences of Human Mobility Restrictions Under COVID-19
A massive analysis on near-real-time Italian mobility data provided by Facebook finds evidence of a segregation effect, since mobility contraction is stronger in municipalities in which inequality is higher and for those where individuals have lower income per capita.
Successional patterns of the insect fauna on a pig carcass in southern Italy and the role of Crematogaster scutellaris (Hymenoptera, Formicidae) as a carrion invader
The seasonal succession of the insect fauna on a pig carcass exposed in a rural area in Calabria (southern Italy) during summer 2007 and 2008 is reported to identify and qualitatively assess the major taxa of forensic importance in this region.

A unified linear analysis of viscous effects on resistive internal kink and tearing modes in current carrying magnetized plasmas is presented. The plasma is modeled by single‐fluid…
Integrated Control of Citrus Pests in the Mediterranean Region
This book presents a definitive exposition of citrus pests and their integrated, mostly non-chemical, control in the Mediterranean area and should be a comprehensive guide for readers interested in citrus crops and integrated pest management.
The olive quick decline syndrome in south-east Italy: a threatening phytosanitary emergency
