Concorso internazionale di progettazione Europan 8 a Ceuta, Spagna

The Benzu area appears as a physical description for the concept of limit, its condition is of marginality to Ceuta’s territory, which is itself as a last piece of land of two continents, somehow illogically distant from both of them. The small urban centre rises up without any plan, and as a consequence it lacks mainly infrastructures and public features. Recognition of Benzu as a whole and of the people as individuals at the same time should be encouraged by means of the public facilities, and, on the other hand, by the dwelling’s urban structure, developed around some of the principles the existing houses are based on. Thematic itineraries are developed through punctual interventions and…

Concorso - Europan 8 a Ceuta (spagna)

L’area di Benzù appare come una descrizione fisica del concetto di limite, la sua condizione di marginalità al territorio di Ceuta, che è esso stesso un pezzo di terra di due continenti, in qualche modo illogicamente distante da entrambi. Il piccolo paese si è sviluppato senza alcun piano, e conseguentemente manca soprattutto di infrastrutture e servizi pubblici, posti dove le persone possono definirsi e riconoscersi come comunità, eccetto che per la moschea, ogni edificio costituisce una singola unità, caratterizzata da un diverso skyline e colore. Il riconoscimento di Benzù nel suo insieme e contemporaneamente delle persone come individui dovrebbe essere incoraggiato da strutture pubblich…

Rates, polarizations, and asymmetries in charmless vector-vector B meson decays

With a sample of approximately 89 million BBbar pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (phi, rho, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B->phiK*+, B->phiK*0, B->rho0K*+, and B->rho0rho+. We also set an upper limit on the branching fraction for the decay B->rho0rho0.

Improved limits on the lepton-flavor violating decays tau(-) -> l(-)l(+)l(-)

A search for the neutrinoless, lepton-flavor violating decay of the tau lepton into three charged leptons has been performed using 376fb-1 of data collected at an e+e- center-of-mass energy around 10.58 GeV with the BABAR detector at the SLAC PEP-II storage rings. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (4-8)×10-8 at 90% confidence level. © 2007 The American Physical Society.

Searches for B0 decays to combinations of charmless isoscalar mesons

We search for B meson decays into two-body combinations of eta, eta', omega, and phi mesons from 89 million B B-bar pairs collected with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find the branching fraction BF(B0 -> eta omega) = (4.0^{+1.3}_{-1.2} +- 0.4) x 10^-6 with a significance of 4.3 sigma. For all the other decay modes we set the following 90% confidence level upper limits on the branching fractions, in units of 10^-6 : BF(B0 -> eta eta)<2.8, BF(B0 -> eta eta')<4.6, BF(B0 -> eta' eta')<10, BF(B0 -> eta'omega)<2.8, BF(B0 -> eta phi)<1.0, BF(B0 -> eta' phi)<4.5, BF(B0 -> phi phi)<1.5.

Effects on the incidence of cardiovascular events of the addition of pioglitazone versus sulfonylureas in patients with type 2 diabetes inadequately controlled with metformin (TOSCA.IT): a randomised, multicentre trial

Background The best treatment option for patients with type 2 diabetes in whom treatment with metformin alone fails to achieve adequate glycaemic control is debated. We aimed to compare the long-term effects of pioglitazone versus sulfonylureas, given in addition to metformin, on cardiovascular events in patients with type 2 diabetes. Methods TOSCA.IT was a multicentre, randomised, pragmatic clinical trial, in which patients aged 50–75 years with type 2 diabetes inadequately controlled with metformin monotherapy (2–3 g per day) were recruited from 57 diabetes clinics in Italy. Patients were randomly assigned (1:1), by permuted blocks randomisation (block size 10), stratified by site and…

Search for correlations between the arrival directions of IceCube neutrino events and ultrahigh-energy cosmic rays detected by the Pierre Auger Observatory and the Telescope Array

This paper presents the results of different searches for correlations between very high-energy neutrino candidates detected by IceCube and the highest-energy cosmic rays measured by the Pierre Auger Observatory and the Telescope Array. We first consider samples of cascade neutrino events and of high-energy neutrino-induced muon tracks, which provided evidence for a neutrino flux of astrophysical origin, and study their cross-correlation with the ultrahigh-energy cosmic ray (UHECR) samples as a function of angular separation. We also study their possible directional correlations using a likelihood method stacking the neutrino arrival directions and adopting different assumptions on the size…
