Re-school. Ripensare la scuola a partire dagli spazi.

Attraverso l’elaborazione di materiale istruttorio, il progetto Re-school si propone di supportare gli enti territoriali nell’individuazione di priorità di intervento sul patrimonio di edilizia scolastica; nella pianificazione strategica a scala regionale e nella definizione di linee guida regionali di intervento sugli edifici scolastici. In questa pubblicazione vengono riassunti i primi passi del gruppo di ricerca e si propone un metodo di lavoro per esplorare il potenziale di trasformazione del patrimonio dell’edilizia scolastica in Italia

Evaluación de algunos parámetros reproductivos en cabras criollas

Se estudiaron 14 cabras y 14 cabrillas de genotipo "regional" o criollas, con el objeto de conocer el comportamiento reproductivo en sistemas semi-intensivos y para determinar la influencia del plano nutricional y edad al servicio sobre la fertilidad(F), la prolificidad (P), y el intervalo entre partos (IEP).Los animales se dividieron al azar en dos grupos de 14, con 7 cabras y 7 cabrillas cada uno, conformándose los siguientes tratamientos: AT (cabra adulta testigo):AS (cabra adulta suplementada); JT (cabra joven testigo); JS (cabra jovensuplementada). Todos los individuos estuvieron sobre pastura natural de crecimiento primavero estival. A los animales de los tratamientos AS y JS se les brindó alimentación suplementaria consistente en 800 grs de heno de alfalfa primerafloración y 200 grs de maíz en grano / madre / día, en servicio, al principio y final de la lactancia. Luego de observar el comportamiento reproductivo de machos y hembras durante todo el año , se consideraron los índices de F, P, e IEP.Los resultados demuestran que hubo diferencias estadísticamente significativas(P < 0,05) en los porcentajes de F entre los tratamientos AS y JS con respecto aAT y JT respectivamente. También hubo diferencias significativas (P< 0,05) cuando se analizó la edad combinada con bajos niveles nutricionales sobre la F y P de las cabras y en cambio no se encontraron diferencias significativas (P > 0.05)en IEP entre los distintos tratamientos, ya que la mayoría de las hembras presentaron anestro estacional de primavera. Se concluye que las cabras criollas delcentro de la provincia de Córdoba (Argentina) se comportan como poliéstricas estacionales, resultando la edad y el nivel nutricional factores restrictivos para el logro del potencial reproductivo de las cabras criollas

Inclusive J/ψ production at mid-rapidity in pp collisions at √s = 5.02 TeV

Inclusive J/ψ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of s = 5.02 TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity (|y| < 0.9) in the dielectron decay channel down to zero transverse momentum pT, using a data sample corresponding to an integrated luminosity of Lint = 19.4 ± 0.4 nb−1. The measured pT-integrated inclusive J/ψ production cross sec- tion is dσ/dy = 5.64 ± 0.22(stat.) ± 0.33(syst.) ± 0.12(lumi.) μb. The pT-differential cross section d2σ/dpTdy is measured in the pT range 0–10 GeV/c and compared with state-of- the-art QCD calculations. The J/ψ 〈pT〉 and 〈pT2〉 are extracted and compared with results obtained at other collision energies. [Figure not available: see fulltext.]

Measurement of Λ (1520) production in pp collisions at √s=7TeV and p–Pb collisions at √sNN=5.02TeV

The production of the Λ (1520) baryonic resonance has been measured at midrapidity in inelastic pp collisions at s=7TeV and in p–Pb collisions at sNN=5.02TeV for non-single diffractive events and in multiplicity classes. The resonance is reconstructed through its hadronic decay channel Λ (1520) → pK - and the charge conjugate with the ALICE detector. The integrated yields and mean transverse momenta are calculated from the measured transverse momentum distributions in pp and p–Pb collisions. The mean transverse momenta follow mass ordering as previously observed for other hyperons in the same collision systems. A Blast-Wave function constrained by other light hadrons (π, K, KS0, p, Λ) describes the shape of the Λ (1520) transverse momentum distribution up to 3.5GeV/c in p–Pb collisions. In the framework of this model, this observation suggests that the Λ (1520) resonance participates in the same collective radial flow as other light hadrons. The ratio of the yield of Λ (1520) to the yield of the ground state particle Λ remains constant as a function of charged-particle multiplicity, suggesting that there is no net effect of the hadronic phase in p–Pb collisions on the Λ (1520) yield

Measurement of electrons from heavy-flavour hadron decays as a function of multiplicity in p-Pb collisions at √sNN = 5.02 TeV

The multiplicity dependence of electron production from heavy-flavour hadron decays as a function of transverse momentum was measured in p-Pb collisions at sNN = 5.02 TeV using the ALICE detector at the LHC. The measurement was performed in the centre-of-mass rapidity interval −1.07 < ycms< 0.14 and transverse momentum interval 2 < pT< 16 GeV/c. The multiplicity dependence of the production of electrons from heavy-flavour hadron decays was studied by comparing the pT spectra measured for different multiplicity classes with those measured in pp collisions (QpPb) and in peripheral p-Pb collisions (Qcp). The QpPb results obtained are consistent with unity within uncertainties in the measured pT interval and event classes. This indicates that heavy-flavour decay electron production is consistent with binary scaling and independent of the geometry of the collision system. Additionally, the results suggest that cold nuclear matter effects are negligible within uncertainties, in the production of heavy-flavour decay electrons at midrapidity in p-Pb collisions.

Measurement of prompt D0, D+, D*+, and DS+ production in p–Pb collisions at √sNN = 5.02 TeV

The measurement of the production of prompt D0, D+, D*+, and DS+ mesons in proton–lead (p–Pb) collisions at the centre-of-mass energy per nucleon pair of sNN = 5.02 TeV, with an integrated luminosity of 292 ± 11 μb−1, are reported. Differential production cross sections are measured at mid-rapidity (−0.96 < ycms< 0.04) as a function of transverse momentum (pT) in the intervals 0 < pT< 36 GeV/c for D0, 1 < pT< 36 GeV/c for D+ and D*+, and 2 < pT< 24 GeV/c for D+ mesons. For each species, the nuclear modification factor RpPb is calculated as a function of pT using a proton-proton (pp) ref- erence measured at the same collision energy. The results are compatible with unity in the whole pT range. The average of the non-strange D mesons RpPb is compared with theoretical model predictions that include initial-state effects and parton transport model predictions. The pT dependence of the D0, D+, and D*+ nuclear modification factors is also reported in the interval 1 < pT< 36 GeV/c as a function of the collision centrality, and the central-to-peripheral ratios are computed from the D-meson yields measured in different centrality classes. The results are further compared with charged-particle measurements and a similar trend is observed in all the centrality classes. The ratios of the pT-differential cross sections of D0, D+, D*+, and DS+ mesons are also reported. The DS+ and D+ yields are compared as a function of the charged-particle multiplicity for several pT intervals. No modification in the relative abundances of the four species is observed with respect to pp collisions within the statistical and systematic uncertainties. [Figure not available: see fulltext.]
