The "Brunella" project: preparation and study of a mysticete from the Early Pliocene of Tuscany

• A project is being carried out at Poggio alle Mura that will allow the preparation and study of a balaenopterid whale from the early Pliocene of Tuscany together with its associated biota. • Up to now, the project resulted in the preparation of 18 vertebrae, the skull and an ulna of the whale. • The associated biota includes 18 mollusk species, 2 sea urchin species, 10 shark teeth and thousands of fish remains from the sediment surrounding the skull. • A wealth of educational activities is being carried out at the laboratory of Poggio alle Mura that are directed to schools and citizens

Outcome of COVID-19 in Patients With Mantle Cell Lymphoma-Report From the European MCL Registry

Data on outcome of patients with mantle cell lymphoma (MCL) and COVID-19 infection are limited. The European MCL (EMCL) registry is a centralized registry of the EMCL network, collecting real-world information about treatments and disease courses. During the COVID-19 pandemic, additional data on MCL patients with COVID-19 infection were collected, aiming to identify risk factors for mortality from COVID-19. In our retrospective, multicenter, international study, we collected data from 63 MCL patients with a median age of 64 years (range, 44–84) in 9 countries with evidence of a COVID-19 infection between February 2020 and October 2021. The overall mortality rate was high (44.4%), especially in hospitalized patients (61%) and in patients with need for intensive care unit care (94%). Patients receiving rituximab had significantly poorer survival than patients not receiving rituximab (P = 0.04). Our data highlight the importance of prevention strategies and underline the need for effective vaccination in this vulnerable cohort

An Energy Storage System Commissioning Tool

Up to few years ago, one of the main problems in the optimal design of a battery energy storage system (BESS) was the availability of both the generation (e.g. renewable sources) and load power profiles of the considered plant. This paradigm has limited the potential of BESSs to drive down overall energy costs and reduce carbon emissions. Nowadays, the exponential growth of data available on the industrial plants has opened the way to new possibilities and opportunities. In addition, BESSs are a viable opportunity to start transforming existing plants with an incremental hybridization of the plant topology. In light of the above, this work develops a commissioning tool that, starting from the data collected on the field, provides the final users the optimal dimensioning of any BESS - according to the taraet performances required bv the specific application

The Key Intermediate in the Aminations of Saturated C-H Bonds: Synthesis, X-ray Characterization and Catalytic Activity of Ru(TPP)(NAr)2 (Ar = 3,5-(CF3)2C6H5)

The complex Ru(TPP)(NAr)2inserts a nitrene group into allylic and benzylic C-H bonds and is the key intermediate in the ruthenium porphyrin-catalyzed amination of hydrocarbons by aryl azides. © 2009 The Royal Society of Chemistry

Origin of the deactivation in styrene aziridination by aryl azides, catalyzed by ruthenium porphyrin complexes. Structural characterization of a Δ2-1,2,3-triazoline RuII(TPP)CO complex

The reaction of Ru(TPP)CO (TPP = dianion of tetraphenylporphyrin) with 1-(p-nitrophenyl)-5-methyl-5-phenyl-1,2,3-triazoline yielded a Δ2-1,2,3-triazoline ruthenium(II) porphyrin complex, which is responsible for the catalyst deactivation in the aziridination reaction of α-methylstyrene by p-nitrophenyl azide. © 2005 American Chemical Society

STABLE ISOTOPE COMPOSITION OF FOSSIL AHERMATYPIC CORAL CLADOCORA CAESPITOSA (L.) FROM PLEISTOCENE RAISED MARINE TERRACES OF THE LIVORNO AREA (CENTRAL ITALY)

The Livorno coastal area (coastal Tuscany) preserves evidences of several raised marine terraces. Stratigraphically they have been correlated with MIS 5e, 9c and MIS 11 sea-level high stands. However, no direct dating have been performed so far. Thanks of new findings of fossil specimens of ahermatypic coral of Cladocora caespitosa in the terraced units correlated to MIS 5e (“Terrazzo di Livorno”) and MIS 11 (“Terrazzo della Fattoria Pianacce”) we attempted direct dating using the U/Th technique. Moreover, stable isotopes (oxygen and carbon) were used for attempting environmental reconstruction. Dating support the correlation of the “Terrazzo di Livorno” unit with the MIS 5e but are inconsistent for the older unit indicating diagenetic Umobilization. Oxygen stable isotopes suggest warmer condition for the MIS 5e and MIS 11 compared to modern conditions, even if the indetermination on the water isotopic composition of past interglacial (i.e. ice volume) hampers our capacity to quantify this values
