Bobbio e il suo contesto
Il saggio \ue8 il frutto di un lavoro in \ue9quipe degli autori (due archeologhe medievali e un filologo germanico) ove ognuno contribuisce con un proprio apporto editorialmente riconoscibile. Lo studio verte sulla collocazione dell'abbazia di Bobbio nel suo contesto territoriale, marcato allo stesso tempo da una continuit\ue0 abitativa e di comunicazioni di et\ue0 tardo-antica e la novit\ue0 dell'insediamento nel medesimo territorio di gruppi di Longobardi e, infine, dei monaci a Bobbio. I dati archeologici, storici paleografici ed epigrafici testimoniano come la comunit\ue0 monastica bobbiese si inserisca nel contesto sotto una matrice di tipo longobardo ma non con una valenza di avamposto di controllo su aree di confine ma, piuttosto, come strumento di sviluppo e ripresa economica. Per quanto riguarda, nello specifico, gli aspetti filologico-testuali, Zironi ha dimostrato come gli usi grafici utilizzati nei laterizi (alcuni di essi ancora inediti) si inseriscano negli usi delle scritture impiegati nel monastero di Bobbio fra VII e VIII secolo, segnalando perci\uf2 una interrelazione fra lo scriptorium e le maestranze artigianali. Infine, l'analisi antroponimica su materiale inedito ha restituito un antroponimo femminile probabilmente longobardo non ancora registrato che permette interessanti riflessioni sulla datazione e diffusione della mutazione consonantica alto-tedesca antica

The Herschel-SPIRE Legacy Survey (HSLS): the scientific goals of a shallow and wide submillimeter imaging survey with SPIRE
A large sub-mm survey with Herschel will enable many exciting science opportunities, especially in an era of wide-field optical and radio surveys and high resolution cosmic microwave background experiments. The Herschel-SPIRE Legacy Survey (HSLS), will lead to imaging data over 4000 sq. degrees at 250, 350, and 500 micron. Major Goals of HSLS are: (a) produce a catalog of 2.5 to 3 million galaxies down to 26, 27 and 33 mJy (50% completeness; 5 sigma confusion noise) at 250, 350 and 500 micron, respectively, in the southern hemisphere (3000 sq. degrees) and in an equatorial strip (1000 sq. degrees), areas which have extensive multi-wavelength coverage and are easily accessible from ALMA. Two thirds of the of the sources are expected to be at z > 1, one third at z > 2 and about a 1000 at z > 5. (b) Remove point source confusion in secondary anisotropy studies with Planck and ground-based CMB data. (c) Find at least 1200 strongly lensed bright sub-mm sources leading to a 2% test of general relativity. (d) Identify 200 proto-cluster regions at z of 2 and perform an unbiased study of the environmental dependence of star formation. (e) Perform an unbiased survey for star formation and dust at high Galactic latitude and make a census of debris disks and dust around AGB stars and white dwarfs
Plankton dynamics across the freshwater, transitional and marine research sites of the LTER-Italy Network. Patterns, fluctuations, drivers
A first synoptic and trans-domain overview of plankton dynamics was conducted across the aquatic sites belonging to the Italian Long-Term Ecological Research Network (LTER-Italy). Based on published studies, checked and complemented with unpublished information, we investigated phytoplankton and zooplankton annual dynamics and long-term changes across domains: from the large subalpine lakes to mountain lakes and artificial lakes, from lagoons to marine coastal ecosystems. This study permitted identifying common and unique environmental drivers and ecological functional processes controlling seasonal and long-term temporal course. The most relevant patterns of plankton seasonal succession were revealed, showing that the driving factors were nutrient availability, stratification regime, and freshwater inflow. Phytoplankton and mesozooplankton displayed a wide interannual variability at most sites. Unidirectional or linear long-term trends were rarely detected but all sites were impacted across the years by at least one, but in many case several major stressor(s): nutrient inputs, meteo-climatic variability at the local and regional scale, and direct human activities at specific sites. Different climatic and anthropic forcings frequently co-occurred, whereby the responses of plankton communities were the result of this environmental complexity. Overall, the LTER investigations are providing an unparalleled framework of knowledge to evaluate changes in the aquatic pelagic systems and management options

From Clouds to Young Stellar Objects and back again: the all-in-one view from the Herschel infrared Galactic Plane Survey
From diffuse interstellar cirrus to dense atomic and molecular clouds, from protostellar to post-AGB envelopes, from super-shells to supernovae remnants, the Herschel Hi-GAL survey offer an unprecedented snapshot of all the different phases of the Galactic ISM, its evolution and interactions. I will present early results on a variety of topics including the lifetime of massive pre-stellar phases, the fragmentation and collapse of extended structures, the timeline for massive star formation, dust properties in cirrus and molecular clouds
