The large eruption 4.2 ka cal BP in Cerro Blanco, Central Volcanic Zone, Andes: Insights to the Holocene eruptive deposits in the southern Puna and adjacent regions. Estudios Geológicos 75(1): e088. https://doi.org/10.3989/egeol.43438.515This dataset compiles SEM images, modelled isopach map and topographic profiles, and data of radiocarbon ages, parameters of Tephra2 and AshCalc codes of Holocene volcanic ashes of of Southern Puna and neighbouring areas (NW Argentina). SEM images detail differences among the Bolsón de Fiambalá, Cerro Blanco and Cueros de Purulla fallout ash deposits. Tephra2 code was used to simulate the ash fallout, and the AshCalc code to compare different methods for ash volume estimates associated with the 4.2 ka cal BP eruption of the Cerro Blanco Volcanic Complex. Topographic profiles are used to explain the secondary thickening of fallout ash deposits.MINECO, CGL2011-23307, Proyecto QUECAPeer reviewe

    Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′

    First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

    1) For whole rock: sieved <180 µm size fraction, pulverized in a vibrating cup laboratory mill, 0.1 g sample digested in HNO3:HClO4:HF (2.5:2.5:5.0, v/v), doubly evaporated to incipient dryness, addition 1 mL HNO3, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm) ; 2) For nitric acid leaching: 0.1 g sample mixed with 1 mL de HNO3 in 12×100-mm polypropylene test tubes In batch experiments, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm). Final solutions were analysed by HR-ICP-MS. Contact person: Fernandez-Turiel, J. L., [email protected] dataset comprises the total and the acid nitric soluble element concentrations of major and trace elements (Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, LOI, As, Ba, Be, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, La, Li, Lu, Mo, Nd, Ni, Pb, Pr, Rb, Sb, Sc, Sm, Sn, Sr, Tb, Th, Tm, U, V, Y, Yb, Zn, Zr) in stream sediments of the Garonne River watershed in the Val d'Aran in the Central Pyrenees. We used samples collected in 1981 in a pilot project of stream sediment geochemistry. The results of nitric acid leachates are used as proxies of the environmentally available fraction of such elements. The samples represents the lithogeochemical units consisting of the Maladeta-Marimanya granitoids, and the metasediments occurring in an extensive area of the basin.Peer reviewe

    Firewall configuration policies for the specification and implementation of private zones

    No full text
    We introduce and discuss two case studies where a complex network is modeled as a set of zones interconnected by routers or firewalls. To address the problem in full abstraction, we defined PDLz, an extension of the PDL event-condition-action language that supports the specification of firewall routing policies. PDLz allows the modelling of computer networks based on the concept of zone, i.e., a TCP/IP subnet where internal traffic remains unconstrained. PDLz policies are enforceable thanks to a direct translation to the IPtables firewall configuration language. At the same time, PDLz has a declarative semantics thanks to translation to logic programs. The logic programming translation also supports, by adding extra rules, the formal verification of properties of the network, viz. off-line reachability testing across firewalls. We describe the application of PDLz to the case studies
