Los cantones suizos: un análisis de su financiación
El presente trabajo tiene por objeto analizar la distribución de recursos entre los cantones suizos y
en particular la contribución de las distintas fuentes de ingresos de los cantones de Suiza a la desigualdad
y la progresividad del sistema de financiación en su conjunto. Tras exponer el objetivo
del trabajo y la revisión de la literatura existente, en el tercer apartado se define el método para
descomponer tanto el índice de desigualdad como el de progresividad. En el apartado cuatro se
presentan los resultados y finalmente se resumen las conclusiones.This paper aims to analyze the distribution of resources within the Swiss Cantons and, in particular,
the contribution of their different sources of income or the inequality and progressivity of their
financing system as a whole. After outlining the aim of this study and revising its existing texts, the
third part defines the method used to decompose both indexes of inequality and progression. The
fourth part presents its results and finally summarizes its conclusions
Validation of Real Case Solving (RCS) Methodology as an Efficient Engineering Learning Tool
In recent times, new learning methodologies known as student-based methodologies have been introduced to simplify the learning process for the students and facilitate the acquisition of skills for them. Among them, problem based learning (PBL) and project-based learning (PjBL) are widely used methods in the world of education. Real case solving (RCS) is a variant of the PBL where students solve real cases through the application of the PBL methodology. RCS seems to be a relevant approach for educators, but it has an apparently limited implementation degree at the academic level. This article presents the successful implementation of four different RCS approaches in the lecturing process in five different classes in the engineering degree of University of Deusto. The initiative has been analyzed both quantitative and qualitatively; the overall performance and success rate of the students were compared with the ones acquired from conventional teaching methods. The results were found to be promising, demonstrating a significantly better performance than the traditional teaching methodologies. The successful results encouraged the university to continue working further in this direction.This research was funded by the X. INNOVATION IN TEACHING CALL OF THE UNIVERSITY OF DEUSTO, project “Application and potential validation of the Real Case Solving methodology as method for relevant learning at the Faculty of Engineering”, and by the BBK Foundation
Comparison of micrometeorological techinques for estimating ammonia emission from covered slurry storage and land spreading of cattle slurry
The micrometeorological mass-balance integrated horizontal flux (IHF) technique has been commonly employed for measuring ammonia (NH3) emissions inon-field experiments. However, the inverse-dispersion modeling technique, such as the backward Lagrangian stochastic (bLS) modeling approach, is currently highlighted as offering flexibility in plot design and requiring a minimum number of samplers (Ro et
al., 2013). The objective of this study was to make a comparison between the bLS technique with the IHF technique for estimating NH3 emission from flexible bag storage and following landspreading of dairy cattle slurry. Moreover, considering that NH3 emission in storage could have been non uniform, the effect on bLS estimates of a single point and multiple downwind concentration measurements was tested, as proposed by Sanz et al. (2010)

Time-Dependent Density-Functional Theory in Massively Parallel Computer Architectures: The Octopus Project
Octopus is a general-purpose density-functional theory (DFT) code, with a particular emphasis on the time-dependent version of DFT (TDDFT). In this paper we present the ongoing efforts to achieve the parallelization of octopus. We focus on the real-time variant of TDDFT, where the time-dependent Kohn–Sham equations are directly propagated in time. This approach has great potential for execution in massively parallel systems such as modern supercomputers with thousands of processors and graphics processing units (GPUs). For harvesting the potential of conventional supercomputers, the main strategy is a multi-level parallelization scheme that combines the inherent scalability of real-time TDDFT with a real-space grid domain-partitioning approach. A scalable Poisson solver is critical for the efficiency of this scheme. For GPUs, we show how using blocks of Kohn–Sham states provides the required level of data parallelism and that this strategy is also applicable for code optimization on standard processors. Our results show that real-time TDDFT, as implemented in octopus, can be the method of choice for studying the excited states of large molecular systems in modern parallel architectures.Chemistry and Chemical Biolog
TXS 2116077: A Gamma-ray Emitting Relativistic Jet Hosted in a Galaxy Merger
What triggers collimated relativistic outflows or jets, from the centers of
galaxies remains a fundamental question in astrophysics. The merging of two
galaxies has been proposed to realize the conditions to successfully launch and
drive such jets into the intergalactic medium. However, evidences for the
operation of this mechanism are scarce. Here we report the first unambiguous
detection of an ongoing merger of a narrow-line Seyfert 1 galaxy, TXS
2116077, hosting a closely aligned, -ray emitting relativistic jet
with a Seyfert 2 galaxy at a separation of 12 kpc, using the observations
taken with 8.2 m Subaru telescope. Our subsequent followup observations with
10.4 m Gran Telescopio Canarias, 4.2 m William Herschel Telescope, and Chandra
X-ray observatory have provided what is likely to be the first glimpse of the
merging environment hosting a closely aligned relativistic jet. Our finding
that the jet is considerably younger than the merger demonstrates that jet
activity can be triggered by galaxy mergers and that -ray detected
narrow-line Seyfert 1 galaxies represent the beginning phase of that activity.
These results also highlight the crucial role of mergers in shaping the fate of
galaxies in their cosmological evolution and are consistent with recent studies
focused on the host galaxy imaging of this enigmatic class of active galactic
nuclei.Comment: 13 pages, 7 figures, 1 table, published in the Astrophysical Journa
