La política de ciencia, tecnología e innovación y el retorno del Estado: 2007-2010, años de inestabilidad The policy of science, technology and innovation and the return of the state: 2007 2010, years of instability
This article analyzes the implementation process of the Ecuadorian science, technology and innovation policy (PCTI) within the framework of the beginning of the post-neoliberal period, which implied the strengthening of the State and the insertion of the paradigm of buen vivir. For this purpose, the novel elements in the definition of this policy under the framework of buen vivir are described as an introductory note. Then, the complex construction process of the explicit PCTI during these years is reviewed. Finally, the instruments implemented and their relationship with the definition of PCTI are analyzed. To this end, the concepts of explicit scientific policy and implicit scientific policy of Herrera [1] and the notion of scientific-technological paradigm of Velho [2] are used. The chosen approach is framed in the new institutionalism that understands the definition and implementation of the PCTI as the result of the strategic game of the actors involved in these processes. This case study uses investigation of historical archives, documentary analysis and in-depth interviews with relevant actors. It is found that the PCTI during these years was unstable, as there were several short-term policy documents, and that its implementation was far from the ambitious rhetoric and the major objectives, limited to two instruments: international postgraduate scholarships and financing of research and development projects

Exploring the metabolic capabilities of purple phototrophic bacteria during piggery wastewater treatment
Producción CientíficaPurple phototrophic bacteria (PPB) are receiving an increasing attention due to their extraordinary metabolic capabilities for nutrient and carbon recovery from wastewaters. Batch experiments were herein performed to assess the influence of the type of radiation (photosynthetic active radiation (PAR), near-infrared radiation (NIR) and PAR using an UV-VIS absorbing filter), temperature (13 °C and 30 °C), type of metabolism (photoheterotrophic and chemoheterotrophic), type of inoculum (mixed culture and pure strain Rhodopseudomonas palustris) and wastewater load (1:5 and 1:10 dilutions) during piggery wastewater (PWW) treatment by PPB. The use of UV-VIS filtered PAR supported both a high content of bacteriochlorophyll in PPB and the highest total organic carbon (TOC) and total nitrogen (TN) removal efficiency (RE) (74 % and 37 %, respectively), but at lower maximum removal rates. Interestingly, PPB exhibited similar TOC-REs and TN-REs (73 % and 37 %, respectively) at 13 °C than at 30 °C (71 % and 45 %, respectively), at similar removal rates. Mixed cultures of PPB achieved a higher nutrient assimilation rate than R. palustris, supporting a total assimilation of the volatile fatty acids present in 10 folds diluted PWW. In brief, mixed cultures of PPB were highly efficient during PWW treatment, regardless of the type of radiation and temperature under photoheterotrophic growth.Junta de Castilla y León - Fondo Europeo de Desarrollo Regional (projects CLU 2017-09, CL-EI-2021-07 and UIC 071)Comisión Nacional de Investigación Científica y Tecnológica (grant PFCHA/DOCTORADO BECAS CHILE/2017 – 72180211
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. IV. Lupus Observed with MIPS
We present maps of 7.78 square degrees of the Lupus molecular cloud complex
at 24, 70, and m. They were made with the Spitzer Space Telescope's
Multiband Imaging Photometer for Spitzer (MIPS) instrument as part of the
Spitzer Legacy Program, ``From Molecular Cores to Planet-Forming Disks'' (c2d).
The maps cover three separate regions in Lupus, denoted I, III, and IV. We
discuss the c2d pipeline and how our data processing differs from it. We
compare source counts in the three regions with two other data sets and
predicted star counts from the Wainscoat model. This comparison shows the
contribution from background galaxies in Lupus I. We also create two color
magnitude diagrams using the 2MASS and MIPS data. From these results, we can
identify background galaxies and distinguish them from probable young stellar
objects. The sources in our catalogs are classified based on their spectral
energy distribution (SED) from 2MASS and Spitzer wavelengths to create a sample
of young stellar object candidates. From 2MASS data, we create extinction maps
for each region and note a strong corresponence between the extinction and the
m emission. The masses we derived in each Lupus cloud from our
extinction maps are compared to masses estimated from CO and CO
and found to be similar to our extinction masses in some regions, but
significantly different in others. Finally, based on our color-magnitude
diagrams, we selected 12 of our reddest candidate young stellar objects for
individual discussion. Five of the 12 appear to be newly-discovered YSOs.Comment: 15 pages, 17 figures, uses emulateapj.cls. Accepted for publication

Relationship between the female attendance pattern and pup growth rate in the South American sea lion (Carnivora)
Changes in the duration and frequency of foraging trips by female otariids may result in changes in the duration and frequency of lactation bouts and hence influence pup growth rate, unless females modify milk energy density and/or the total amount of milk delivered depending on the trip duration. To test this hypothesis on South American sea lions, we measured two attendance pattern components (foraging trip and haul-out duration) and three diving behaviour components of nursing females (dive time, bottom time and number of dives per h) at two different rookeries in Uruguay and Argentina, the composition and energy density of their milk, and the growth rate of their pups. Female foraging trip and haul-out durations depended on pup sex and weight, whereas milk energy density depended on female body mass and foraging trip durations. By contrast, the three dive variables were independent of female body mass or pup sex. Pup growth was also independent of the foraging trip and haul-out duration, with pup sex as the only significant variable. This suggests that individual differences in female foraging behaviour play a minor role in determining pup growth rates during the first three weeks after birth

Calibration of the charge and energy loss per unit length of the MicroBooNE liquid argon time projection chamber using muons and protons
We describe a method used to calibrate the position- and time-dependent response of the MicroBooNE liquid argon time projection chamber anode wires to ionization particle energy loss. The method makes use of crossing cosmic-ray muons to partially correct anode wire signals for multiple effects as a function of time and position, including cross-connected TPC wires, space charge effects, electron attachment to impurities, diffusion, and recombination. The overall energy scale is then determined using fully-contained beam-induced muons originating and stopping in the active region of the detector. Using this method, we obtain an absolute energy scale uncertainty of 2% in data. We use stopping protons to further refine the relation between the measured charge and the energy loss for highly-ionizing particles. This data-driven detector calibration improves both the measurement of total deposited energy and particle identification based on energy loss per unit length as a function of residual range. As an example, the proton selection efficiency is increased by 2% after detector calibration

Reconstruction and measurement of (100) MeV energy electromagnetic activity from π0 arrow γγ decays in the MicroBooNE LArTPC
We present results on the reconstruction of electromagnetic (EM) activity from photons produced in charged current νμ interactions with final state π0s. We employ a fully-automated reconstruction chain capable of identifying EM showers of (100) MeV energy, relying on a combination of traditional reconstruction techniques together with novel machine-learning approaches. These studies demonstrate good energy resolution, and good agreement between data and simulation, relying on the reconstructed invariant π0 mass and other photon distributions for validation. The reconstruction techniques developed are applied to a selection of νμ + Ar → μ + π0 + X candidate events to demonstrate the potential for calorimetric separation of photons from electrons and reconstruction of π0 kinematics
Red de coordinación para las asignaturas transversales en el Grado en Traducción e Interpretación
Una vez transcurridos cuatro años desde que, a tenor de lo establecido en la «Declaración de Bolonia» de 1999, se implantara con las correspondientes reformas del sistema educativo, entre otros títulos oficiales, el Grado en Traducción e Interpretación en la Universidad de Alicante, la comunidad universitaria requiere instrumentos de análisis para valorar la convergencia de las asignaturas de que consta. En el seno del Proyecto Redes de Investigación en Docencia Universitaria, promovido por el Instituto de Ciencias de la Educación de la Universidad de Alicante, el cometido de la «Red de Coordinación para las asignaturas transversales en el Grado en Traducción e Interpretación» (código 3164) ha consistido en dotar de mayor coherencia a las asignaturas «Documentación aplicada a la Traducción», «Lingüística aplicada a la Traducción» y «Teoría e Historia de la Traducción», dado el carácter acumulativo y secuencial de las mismas, con el fin de mejorar el proceso de enseñanza-aprendizaje dentro y fuera del aula. En el presente trabajo se expondrá la labor desarrollada por los miembros de la red para llevar a cabo dicho objetivo
