Measurement of the atmospheric muon depth intensity relation with the NEMO Phase-2 tower

The results of the analysis of the data collected with the NEMO Phase-2 tower, deployed at 3500 m depth about 80 km off-shore Capo Passero (Italy), are presented. Cherenkov photons detected with the photomultipliers tubes were used to reconstruct the tracks of atmospheric muons. Their zenith-angle distribution was measured and the results compared with Monte Carlo simulations. An evaluation of the systematic effects due to uncertainties on environmental and detector parameters is also included. The associated depth intensity relation was evaluated and compared with previous measurements and theoretical predictions. With the present analysis, the muon depth intensity relation has been measured up to 13 km of water equivalent.Comment: submitted to Astroparticle Physic

Discovery of a bipolar and highly variable mass outflow from the symbiotic binary StHa 190

A highly and rapidly variable bipolar mass outflow from StHa 190 has been discovered, the first time in a yellow symbiotic star. Permitted emission lines are flanked by symmetrical jet features and multi-component P-Cyg profiles, with velocities up to 300 km/sec. Given the high orbital inclination of the binary, if the jets leave the system nearly perpendicular to the orbital plane, the de-projected velocity equals or exceeds the escape velocity (1000 km/sec). StHa190 looks quite peculiar in many other respects: the hot component is an O-type sub-dwarf without an accretion disk or a veiling nebular continuum and the cool component is a G7 III star rotating at a spectacular 105 km/sec unseen by a large margin in field G giants.Comment: Letter to the Editor, Astron.Astrophys, in pres

Synthesis of pyrazole containing α-amino acids via a highly regioselective condensation/aza-Michael reaction of β-aryl α,β-unsaturated ketones

A synthetic approach for the preparation of a new class of highly conjugated unnatural α-amino acids bearing a 5-arylpyrazole side-chain has been developed. Horner–Wadsworth–Emmons reaction of an aspartic acid derived β-keto phosphonate ester with a range of aromatic aldehydes gave β-aryl α,β-unsaturated ketones. Treatment of these with phenyl hydrazine followed by oxidation allowed the regioselective synthesis of pyrazole derived α-amino acids. As well as evaluating the fluorescent properties of the α-amino acids, their synthetic utility was also explored with the preparation of a sulfonyl fluoride derivative, a potential probe for serine proteases

INTERSTICE. Encounters between artists, children and educators. Thoughts in-between the arts and education

INTERSTICE is an Erasmus+ project developed by universities, artists and cultural settings from Catalonia, United Kingdom, Italy, and Norway to promote spaces of encounter between educators, artists, and children, to improve our learning processes and to build a pedagogy of co-creation through the arts. This is the main product of INTERSTICE project, a collaborative book where project partners share the key ingredients that we think are necessary to build creative approaches to learning

The global financial crisis and developing countries

When the global financial crisis broke out in earnest in September 2008, it quickly became clear that developing countries would also be affected, but that the impacts would vary markedly. The Overseas Development Institute (ODI) coordinated a multi-country study over January-March 2009 involving developing country teams in 10 countries. This showed that, while the transmission mechanisms were similar in each (trade, private capital flows, remittances, aid), the effects varied by country, and much was not yet visible. As such, further country-specific monitoring was required. Most findings suggested that, as a result of time lags, the worst effects were yet to come. This synthesis of the effects of the global financial crisis on developing countries updates the description of the economic and social situation during the course of the crisis in 11 countries

Metabolic Effects of Aripiprazole and Pimozide in Children With Tourette Syndrome

This study assessed the metabolic effects of aripiprazole and pimozide in pediatric Tourette syndrome, a neurodevelopmental condition characterized by multiple motor and phonic tics. Patients receiving aripiprazole (n = 25) or pimozide (n = 25) were compared with medication-free patients (n = 25). Body mass index, glycemia, triglyceridemia, and cholesterolemia were monitored at baseline and 12 and 24 months after commencing treatment. The aripiprazole group demonstrated significant increases in cholesterolemia. The pimozide group demonstrated significant increases in glycemia. Both groups demonstrated elevations in triglyceridemia not significantly different from those in unmedicated control subjects. The effect of aripiprazole on cholesterol was apparent after 12 months, but leveled off during year 2 of treatment. Longitudinal studies are required to evaluate the full extent of glycemic alterations with pimozide. Both agents appear relatively safe for use in pediatric Tourette syndrome. These findings will help guide medication selection in patients with specific medical vulnerabilities.</p
