Rheology of primitive alkaline basalts: constraints on the pre-eruptive system of Campi Flegrei (Naples, Italy)
The knowledge of the rheology of magmas at high
pressure and temperature is of fundamental importance to
model their mobility, ascent rate and volcanic activity at
surface. In this study, we determined the viscosity and the
atomic structure of the nominally anhydrous APR16 alkali
basalt representative of the least-evolved magmas of
Phlegrean Volcanic District (Phlegrean Fields, Italy;
Bonechi et al., 2017). The sample is a lithic fragment
belonging to the Solchiaro hydromagmatic tuff of Procida
island, characterized by a porphyritic texture (P.I. 12%
volume) with phenocrysts of olivine (Fo85-80),
occasionally hosting Cr-spinel grains (Cr# ~0.50), and
clinopyroxene (Wo46-48 En46-31 Fs6-23), and a
groundmass made of olivine, clinopyroxene, plagioclase
(An79-52), Ti-magnetite (Usp4.1-4.4). The APR16 has
[Mg/(Mg+Fe)] 0.66, 49 wt% SiO2, 4.4 wt% of total alkali
(Na2O+K2O) and ~12 wt% of CaO. The anhydrous glass
was prepared at Bayerisches Geoinstitut by using a gasmixing
furnace. The rock powder was melted at 1400 °C
for 15 minutes at atmospheric pressure and oxygen
fugacity buffered at Nickel-Nickel Oxide level using a
CO/CO2 gas mixture. The viscosity of glassy APR16 was
determined by the in situ falling sphere technique at P of
0.7-2.5 GPa and T of 1335-1700°C using the Paris-
Edinburgh press available at the 16BMB beamline at the
Advanced Photon Source (Argonne National Lab, Illinois,
USA). The falling velocity of the Pt probing spheres was
measured by X-ray imaging using a high-speed camera
recording 500 frames per second. In addition, analyses of
the melt structure were performed by using multi-angle
energy dispersive X-ray diffraction technique. Preliminary
data show the viscosity being in the range of 0.1-1 Pa·s at
the target P and T. These viscosity values can be used to
model the mobility and ascent velocity of primitive alkali
basalts considered to be parental magmas at Campi Flegrei
with important implications for the volcanic hazard of the
area over time
Mobile epifaunal assemblages associated with Cystoseira beds: comparison between invaded and non-invaded areas by Lophocladia lallemandii.

Assessing Gender Equality and Inclusivity: a Survey within the Italian Life Sciences Sector.
Despite recognized needs for women's full participation and fair leadership in political and economic decisions, notable gender gaps persist. This study examines gender equality, inclusivity, and opportunities in Italian life sciences companies. An ad hoc questionnaire was completed by HR professionals in this sector, capturing insights on women's roles, responsibilities, and seniority in management and on boards. It also aims to forecast the future integration of female leadership and assesses supportive company policies like flexible schedules, part-time options, remote work, and family-centric initiatives
Modelling energy fluxes in remote wetland ecosystems with help of remote sensing
The study of the material and energy fluxes that characterise an ecosystem is fundamental to understanding the
behaviour of that system and its resiliency in the face of changing local and global conditions. In the present research,
an extended energy balance model was used to examine the fluxes that characterise the energy exchange between a
large wetland area and its environment. For each flux term, a number of modelling approaches was compared.
Modelling was complemented through the use of irradiance measurements from satellite data. The model output
shows the daily and season variations in each energy term, as well as a comparison of the modelling approaches. The
final output of the model is validated with the measured hourly variation in the enthalpy (water temperature) of the
lagoon. A comparison is made of the relative importance of each energy term in the overall balance of the system.
This physical based model is being used to examine possible modifications of local and global environments to the
wetland energy balance. The model is also being combined with fauna models to examine the relation between climate
and population characteristics (habitat). The present work is directed towards the study of a subtropical lagoon in the
internationally important wetland, the Esteros del Ibera in Argentin
Interaction of Quercetin and its conjugate Quercetin 3-b-D-glucoside with Albumin Determined by NMR Relaxation Data
NMR methodology has been developed in order to study phytochemical-macromolecular receptor interactions. This
approach is based on the analysis of proton selective spin–lattice relaxation rate enhancements of the ligand in the
presence of the macromolecule, to calculate an affinity index, [A]
, related to the strength of the interaction process.
This index has been modified by normalization to the relaxation rate of the free ligand, in order to take into account the
effects of motional anisotropies and different proton densities. The normalized affinity index, [A
L
T
N
]
, isolates the contribution
due to a decrease in the ligand dynamics caused by the binding with the protein. This methodology has been applied
to the interaction between two flavonoids (quercetin, 1, and quercetin 3-O-D-glucopyranoside,
2) and bovine serum
albumin (BSA). The calculated values of the affinity indexes and thermodynamic equilibrium constants suggested a
much stronger capacity of 1 to interact with BSA when compared with its glucosylated derivative, 2
