Charged-current inclusive neutrino cross sections in the SuperScaling model including quasielastic, pion production and meson-exchange contributions

Charged current inclusive neutrino-nucleus cross sections are evaluated using the superscaling model for quasielastic scattering and its extension to the pion production region. The contribution of two-particle-two-hole vector meson-exchange current excitations is also considered within a fully relativistic model tested against electron scattering data. The results are compared with the inclusive neutrino-nucleus data from the T2K and SciBooNE experiments. For experiments where $\langle E_\nu \rangle \sim 0.8$ GeV, the three mechanisms considered in this work provide good agreement with the data. However, when the neutrino energy is larger, effects from beyond the $\Delta$ also appear to be playing a role. The results show that processes induced by two-body currents play a minor role at the kinematics considered.Comment: 10 pages, 7 figure

Meson-exchange currents and quasielastic predictions for charged-current neutrino-12C scattering in the superscaling approach

We evaluate and discuss the impact of meson-exchange currents (MECs) on charged-current quasielastic neutrino cross sections. We consider the nuclear transverse response arising from two-particle two-hole states excited by the action of electromagnetic, purely isovector meson-exchange currents in a fully relativistic framework based on the work by the Torino Collaboration [A. D. Pace, M. Nardi, W. M. Alberico, T. W. Donnelly, and A. Molinari, Nucl. Phys. A726, 303 (2003)]. An accurate parametrization of this MEC response as a function of the momentum and energy transfers involved is presented. Results of neutrino-nucleus cross sections using this MEC parametrization together with a recent scaling approach for the one-particle one-hole contributions (named SuSAv2) are compared with experimental data (MiniBooNE, MINERvA, NOMAD and T2K Collaborations).Comment: 16 pages, 19 figure

Radioterapia combinada con quimioterapia en el tratamiento del cáncer de pulmón

El empleo conjunto de radioterapia y quimioterapia en el cáncer de pulmón no metastásico (microcítico y no microcítico) permite combi- nar los benefi cios de la radioterapia en términos de control local con aquellos conseguidos por la quimioterapia erradicando la enfermedad micrometastásica. Diversos estudios aleatorizados han demostrado que la radioterapia radical combinada con quimioterapia mejora la supervi- vencia de estos pacientes, a expensas de un incremento de la toxicidad. El desarrollo tecnológico y los avances en programas informáticos han posibilitado la introducción de nuevos aceleradores lineales comunicados con sofi sticados sistemas de planifi cación tridimensional que permiten administrar dosis mayores de irradiación al volumen tumoral diana y menores dosis de irradiación sobre estructuras sanas (pulmón, corazón, esófago y médula espinal). El resultado fi nal es un incremento del índice terapéutico debido a un probable benefi cio en el control local y una disminución de los efectos adversos de la irradiación. El volumen de irradiación, la dosis total a administrar, el fraccionamiento de la dosis, el tipo de esquema de combinación de la radioterapia con la quimiotera- pia, así como la infl uencia en la supervivencia de la irradiación cerebral profi láctica en el caso del cáncer microcítico de pulmón son temas de discusión en la actualidad. INGLÉS: The combination of radiotherapy and chemotherapy in lung cancer (locally advanced non-small and small cell) may offer the benefits of radiotherapy in terms of local control and those of chemotherapy in terms of reducing metastatic dissemination of the disease. Several randomized studies have showed that radical radiotherapy combined with chemotherapy improves the survival of these patients at the expense of an increase in toxicity. The technological development and the improvements in software have allowed the introduction of new linear accelerators and a three-dimensional planning system with the intention of delivering higher irradiation doses in the tumor target, and minimizing the dose in adjacent normal tissues (lung, heart, esophagus and spinal cord). The volume of irradiation, the total dose, the fractionation, the schedule for the combination of radiotherapy and chemotherapy, as well as the influence of the prophylactic cranial irradiation in small cell lung cancer are points for discussion at the moment

Microporosity in aluminium foams

We studied microporosity in the metallic matrix of aluminium foams produced by the powder metallurgical route both with and without application of a blowing agent. Microporosity was studied in situ in liquid metal foams as well as ex situ in the solidified microstructures. In situ studies were carried out using synchrotron X rays. Quantitative analyses of the amount and distribution of microporosity inside cell walls, Plateau borders and nodes were performed on 2D micrographs and on 3D reconstructed volumes generated by X ray tomography. We studied the influence of alloying elements, blowing agent and holding time on the amount and type of micropores. The mechanisms of microporosity formation and the evolution of microporosity via diffusion of hydrogen and by coalescence are discussed. It was observed that alloy composition and holding time have a strong influence on microporosity. Different possible strategies to control microporosity are suggeste

Random scenarios generation with minimun energy consumption model for sectoring optimization in pressurized irrigation networks using a simulated annealing approach

A pressurized irrigation network may operate in two ways, namely, on demand and organized under operating sectors. In the first case, the user decides when to irrigate, and the pumping station has to meet the discharge and pressure head requirements of the group of users that is demanding water at any time. In the second case, the operating hydrants at a given moment are previously established, which permits identification of scenarios related to lesser energy consumption. In this work, a new model was developed that identifies such scenarios. The optimization process is carried out by means of simulated annealing (SA). The model was applied to an example and the result obtained was compared with the same network operating on demand and sectorized using the criterion of hydrant elevation with respect to the pumping station. The scenario adopted for SA saved 11.8% and 15.5% in energy consumption compared with the two other scenarios, and decreased the installed power requirement by 38.3% and 21.6%, respectively.García Prats, A.; Guillem Picó, S.; Martínez Alzamora, F.; Jiménez Bello, MA.

Evaluation of bread quality and volatile compounds of breads made by sourdoughs fermented by sediments of pulque (xaxtle) as starter culture

Sourdough is an important modern fermentation method of cereal flour and water. The fermentation process is carried out by lactic acid bacteria (LAB) and yeasts which confer specific flavor characteristics to the bread. The main aim of this research was to investigate the bread quality and volatile compounds of breads made by sourdoughs inoculated with sediments of pulque (xaxtle) used it as starter culture. Fifty five volatile compounds were found in the bread made with sourdoughs inoculated with xaxtle from three different regions of Mexico. Using gas chromatography-mass spectrometry, compounds as 3-hydroxy-2-butanone; 3-methyl-1-butanol; 2-methyl, 1-butanol; dimethyl disulfide; furfural, nonanal, phenyl ethyl alcohol and butanoic acid were presented in the flavor profile of the breads and having a positive response to sensory analysis made by evaluators. The xaxtle of Nanacamilpa (XN) and the xaxtle of Villa Alta (XV) were the best breads getting 8.3±0.03, 8.8±0.02, 6.2±0.08 and 8.2±0.01 scores in a scale from 0 to 10 in color, smell, texture and flavor attributes respectively which are positive attributes in favor of the quality bread. As a result of fermentation sourdough with LAB and yeasts from the xaxtle during 24 hours (30° C), the bread made with the sourdough inoculated with xaxtle of Milpa Alta (XM) showed the major acid flavor therefore its sample was less acceptable getting 8.1±0.01, 7.8±0.02, 5.3±0.01 and 7.9±0.01 in the same attributes evaluated. The xaxtle of Nanacamilpa, Tlaxcala (XN) run better than the others as starter fermentation culture for sourdoughs
