Authors: Lacalle Zalduendo Charo , Hidalgo-Marí Tatiana 
Published: May 2016

El presente trabajo analiza la evolución de la familia en las ficciones de la televisión española, con especial atención a la representación del papel y el rol que ocupan las mujeres. Metodología. El análisis se ha realizado sobre los 709 personajes que han participado, con diferentes grados de protagonismo, en la ficción de estreno emitida a lo largo de 2013 y 2014 por las cadenas estatales y autonómicas: series, seriales, miniseries, TVmovies y tiras cómicas. Conclusiones y discusión. El estudio evidencia que la representación de las familias en la ficción se sigue llevando a cabo, en muchos casos, desde el prisma de la familia tradicional, aunque se incorporan cada vez más roles más innovadores más fieles a la realidad social que sustenta dichas ficciones televisivas.

Abstract. The aim of the present study was to investigate the effect of in ovo feeding (IOF) of glutamine on hatchability, development of the gastrointestinal tract, growth performance and carcass characteristics of broiler chickens. Fertilized eggs were subjected to injections with glutamine (Gln) (10, 20, 30, 40 or 50 mg dissolved in 0.5 mL of dionized water) on day 7 of incubation. Hatchability, growth performance, carcass characteristics (carcass weight and relative weights of breast, thigh, heart, liver, gizzard, abdominal fat, intestine, pancreas and spleen) and jejunal morphometry (measurement of villus height and width and crypt depth) were determined during the experiment. The weight of newly hatched chickens was significantly greater in groups with Gln injection than in control and sham groups. But IOF caused lower hatchability than in the control group (non-injected eggs) (p < 0.05). Chickens from IOF of Gln showed better weight gain and feed conversion ratio (0–42 days of age), when compared to chickens hatched from control and sham groups. The IOF of Gln significantly increased villus height, villus width and crypt depth at hatch period and villus height at 42 days of age. In addition, carcass weights and relative weights of breast, thigh and gizzard were also markedly increased in chickens treated in ovo with Gln; whereas heart, liver, abdominal fat, intestine, pancreas and spleen were not significantly altered at the end of the experimental period. These data suggest that the IOF of Gln may improve jejunum development, leading to an increased nutrient assimilation and consequently to greater performance in broiler chickens.

Abstract. This study focuses on the quantification and analysis of geomorphic processes on the barely vegetated slopes of a recultivated iron ore mine on the Italian island of Elba using photographs from terrestrial laser scanning (TLS) and digital photogrammetry by an unmanned aerial vehicle (UAV) over a period of 5 1/2 years. Beside this, the study tried to work out the potential and the limitations of both methods to detect surface changes by geomorphic process dynamics within a natural environment. Both UAV and TLS show the pattern of the erosion and accumulation processes on the investigated slope quite well, but the calculated amounts differ clearly between the methods. The reasons for these differences could be found in the different accuracies (variable level of detections) of the methods and the different viewing geometries. Both effects have an impact on the detectable process dynamics over different timescales on the slope and their calculated amounts, which in both cases can lead to an underestimation of erosion and accumulation by fluvial processes.
Le rapport mondial de l’UNESCO sur les sociétés du savoir. État des lieux au Québec, dix ans plus tard
Authors: Bernatchez Jean 
Published: May 2016

Le rapport mondial de l’UNESCO sur les sociétés du savoir, publié en 2005, incarne l’idéal de la science au service du développement humain. Le modèle qui y est décrit constitue une solution de remplacement à celui de l’économie du savoir, proposé par l’OCDE en 1996, lequel inspire les politiques scientifiques des pays industrialisés. Nous reprenons dans cet article trois thèmes centraux du rapport de l’UNESCO sur les sociétés du savoir et nous déclinons les valeurs et les normes qui les orientent : la gouvernance de la science, l’organisation de la recherche scientifique et l’évolution de l’enseignement supérieur. Pour chaque thème, nous dressons un état des lieux au Québec selon l’idéal des sociétés du savoir.
Faire l’économie du savoir. Usages et représentations du financement public des universités du Québec, de l’après-guerre à la Révolution tranquille (1950-1968)
Authors: Racine St-Jacques Jules , Maltais Martin 
Published: May 2016

Le présent article retrace les principales manifestations de la culture politique dans laquelle se sont implantées les premières politiques publiques de financement universitaire au Québec entre 1950 et 1968. Les années 1950-1960 sont marquées par un faible degré de normalisation et un manque de planification du développement universitaire. Les institutions d’enseignement supérieur sont alors considérées par le pouvoir d’un point de vue humaniste, au même titre que les organismes culturels. Bien qu’elles tendent à produire de nouvelles élites, ces institutions demeurent vouées à la reproduction de l’ordre social traditionnel. Durant la Révolution tranquille, l’enseignement supérieur est davantage pris en charge par l’appareil étatique québécois, qui s’outille pour pourvoir aux besoins grandissants d’une population en croissance et d’un État en expansion. Cette période est marquée par des efforts de systématisation du mode de financement, mais ceux-ci demeurent teintés d’une culture discrétionnaire persistante. La représentation humaniste de l’université cède progressivement le pas à une idée d’université qui la dépeint comme un rouage essentiel du développement socioéconomique.
Influence of electric fields on absorption spectra of AAB-stacked trilayer graphene
Authors: Chiu Chih-Wei , Chen Rong-Bin 
Published: May 2016

Abstract
The tight-binding model and gradient approximation are, respectively, used to calculate the band structures and the absorption spectra of AAB-stacked trilayer graphene (AAB-TLG). AAB stacking, the lowest symmetric geometric structure in trilayer systems, induces the most atomic interactions, and thus, complicates the energy dispersions and the joint density of states. AAB stacking enriches the optical absorption spectra [A(ω)], which dictate the characteristics of the electronic structure. A(ω) are changed by the static electric field, such as the intensity, frequency, and number of absorption structures. These results contrast sharply with those for TLG in other stacking configurations.

Abstract
Micrometer-scale responses of radio-photoluminescence (RPL) glass dosimeters to focused ionized particle radiation were evaluated by combining ion-beam-induced luminescence (IBIL) and proton beam writing (PBW) using a 3 MeV focused proton microbeam. RPL phosphate glass dosimeters doped with ionic Ag or Cu activators at concentrations of 0.2 and 0.1% were fabricated, and their scintillation intensities were evaluated by IBIL spectroscopy under a PBW micropatterning condition. Compared with the Ag-doped dosimeter, the Cu-doped dosimeter was more tolerant of the radiation, while the peak intensity of its luminescence was lower, under the precise dose control of the proton microprobe. Proton-irradiated areas were successfully recorded using these dosimeters and their RPL centers were visualized under 375 nm ultraviolet light. The reproduction of the irradiated region by post-RPL imaging suggests that precise estimation of irradiation dose using microdosimeters can be accomplished by optimizing RPL glass dosimeters for various proton microprobe applications in organic material analysis and in micrometer-scale material modifications.

Abstract
We report a novel low-power nitriding technique by utilizing a 2.45 GHz microwave-excited nitrogen radical flow system. Nitrogen plasma was produced at the nozzle with dimensions of 50 × 0.5 mm2 and blown onto the surface of a target substrate. A titanium substrate has been used as a target plate since it is easy to visualize a nitriding effect. The titanium substrate was treated under the conditions of 60 W microwave power, 20 Torr of nitrogen gas pressure, and a plate temperature of ∼800 °C. As a result, we have succeeded in nitriding of the titanium substrate in a quasi-atmospheric region of 20 Torr and of a very low power of 60 W with the hardness kept high, which is almost the same as the hardness processed by conventional nitriding methods.
Simulations of ionospheric turbulence produced by HF heating near the upper hybrid layer

AbstractHeating of the ionosphere by high‐frequency (HF), ordinary (O) mode electromagnetic waves can excite magnetic field‐aligned density striations, associated with upper and lower hybrid turbulence and electron heating. We have used Vlasov simulations in one spatial and two velocity dimensions to study the induced turbulence in the presence of striations when the O‐mode pump is mode converted to large‐amplitude upper hybrid oscillations trapped in a striation. Parametric processes give rise to upper and lower hybrid turbulence, as well as to large amplitude, short wavelength electron Bernstein waves. The latter excite stochastic electron heating when their amplitudes exceed a threshold for stochasticity, leading to a rapid increase of the electron temperature by several thousands of kelvin. The results have relevance for high‐latitude heating experiments.
Ridge‐spotting: A new test for Pacific absolute plate motion models
Authors: Wessel Paul , Müller R. Dietmar 
Published: May 2016

AbstractRelative plate motions provide high‐resolution descriptions of motions of plates relative to other plates. Yet geodynamically, motions of plates relative to the mantle are required since such motions can be attributed to forces (e.g., slab pull and ridge push) acting upon the plates. Various reference frames have been proposed, such as the hot spot reference frame, to link plate motions to a mantle framework. Unfortunately, both accuracy and precision of absolute plate motion models lag behind those of relative plate motion models. Consequently, it is paramount to use relative plate motions in improving our understanding of absolute plate motions. A new technique called “ridge‐spotting” combines absolute and relative plate motions and examines the viability of proposed absolute plate motion models. We test the method on six published Pacific absolute plate motions models, including fixed and moving hot spot models as well as a geodynamically derived model. Ridge‐spotting reconstructs the Pacific‐Farallon and Pacific‐Antarctica ridge systems over the last 80 Myr. All six absolute plate motion models predict large amounts of northward migration and monotonic clockwise rotation for the Pacific‐Farallon ridge. A geodynamic implication of our ridge migration predictions is that the suggestion that the Pacific‐Farallon ridge may have been pinned by a large mantle upwelling is not supported. Unexpected or erratic ridge behaviors may be tied to limitations in the models themselves or (for Indo‐Atlantic models) discrepancies in the plate circuits used to project models into the Pacific realm. Ridge‐spotting is promising and will be extended to include more plates and other ocean basins.
The graded alluvial river: Profile concavity and downstream fining
Authors: Blom Astrid , Viparelli Enrica , Chavarrías Víctor 
Published: May 2016

AbstractThere has been quite some debate on the relative importance of particle abrasion and grain size selective transport regarding the river profile form and the associated grain size trends in a graded alluvial stream. Here we present new theoretical equations for the graded alluvial river profile that account for the effects of particle abrasion and grain size selective transport in the absence of subsidence, uplift, and sea level change. Under graded conditions we find that abrasion results in a mild profile concavity and downstream fining, whereas under aggradational conditions grain size selective transport can lead to large spatial changes in channel slope and bed surface mean grain size.

AbstractThe first in situ measurements of electric and magnetic fields in the near‐Sun environment (< 0.25 AU from the Sun) will be made by the FIELDS instrument suite on the Solar Probe Plus mission. The Digital Fields Board (DFB) is an electronics board within FIELDS that performs analog and digital signal processing, as well as digitization, for signals between DC and 60 kHz from five voltage sensors and four search coil magnetometer channels. These nine input signals are processed on the DFB into 26 analog data streams. A specialized application‐specific integrated circuit performs analog to digital conversion on all 26 analog channels simultaneously. The DFB then processes the digital data using a field programmable gate array (FPGA), generating a variety of data products, including digitally filtered continuous waveforms, high‐rate burst capture waveforms, power spectra, cross spectra, band‐pass filter data, and several ancillary products. While the data products are optimized for encounter‐based mission operations, they are also highly configurable, a key design aspect for a mission of exploration. This paper describes the analog and digital signal processing used to ensure that the DFB produces high‐quality science data, using minimal resources, in the challenging near‐Sun environment.
Normal faulting in the Simav graben of western Turkey reassessed with calibrated earthquake relocations

Published: May 2016

AbstractWestern Turkey has a long history of large earthquakes, but the responsible faults are poorly characterized. Here we reassess the past half century of instrumental earthquakes in the Simav‐Gediz region, starting with the 19 May 2011 Simav earthquake (Mw 5.9), which we image using interferometric synthetic aperture radar and regional and teleseismic waveforms. This event ruptured a steep, planar normal fault centered at 7–9 km depth but failed to break the surface. However, relocated main shock and aftershock hypocenters occurred beneath the main slip plane at 10–22 km depth, implying rupture initiation in areas of low coseismic slip. These calibrated modern earthquakes provide the impetus to relocate and reassess older instrumental events in the region. Aftershocks of the 1970 Gediz earthquake (Mw 7.1) form a narrow band, inconsistent with source models that invoke low‐angle detachment faulting, and may include events triggered dynamically by the unilateral main shock rupture. Epicenters of the 1969 Demirci earthquakes (Mw 5.9, 6.0) are more consistent with slip on the south dipping Akdağ fault than the larger, north dipping Simav fault. A counterintuitive aspect of recent seismicity across our study area is that the largest event (Mw 7.1) occurred in an area of slower extension and indistinct surface faulting, yet ruptured the surface, while recent earthquakes in the well‐defined and more rapidly extending Simav graben are smaller (Mw <6.0) and failed to produce surface breaks. Though our study area bounds a major metamorphic core complex, there is no evidence for involvement of low‐angle normal faulting in any of the recent large earthquakes.
On the statistics of SuperDARN autocorrelation function estimates
Authors: Reimer A. S. , Hussey G. C. , Dueck S. R. 
Published: May 2016

AbstractTime domain signal processing techniques are employed by the Super Dual Auroral Radar Network (SuperDARN) to obtain bulk measurements of the velocity and spectral width of F region ionospheric plasma irregularities. The measurements are obtained by fitting estimates of the mean autocorrelation function (ACF) of the radar target. To accurately and consistently extract target parameters from the mean unnormalized ACF, it is necessary to utilize error‐weighted fitting algorithms with a weight given by the variance of the ACF. Currently implemented weights are ad hoc, and a detailed description of the statistical characterization of SuperDARN ACFs is needed. Following the discussions in Farley (1969) and Woodman and Hagfors (1969), which describe the variance for the mean normalized ACF used with incoherent scatter radars, we present analytic expressions for obtaining the variance of the real and imaginary components of the mean unnormalized SuperDARN ACF. These expressions are based on models by André et al. (1999) and Moorcroft (2004) of the voltage signal received by SuperDARN radars but may be used for other soft target radar systems. An algorithm for obtaining the variance of both the magnitude and phase of the mean ACF is also presented. The results of this study may be directly integrated into existing SuperDARN data analysis software and other pulse‐Doppler radar systems that utilize estimates of the mean unnormalized ACF.
Measurement and modeling of engineered nanoparticle transport and aging dynamics in a reactive porous medium
Authors: Naftaly Aviv , Dror Ishai , Berkowitz Brian 
Published: May 2016

AbstractA continuous time random walk particle tracking (CTRW‐PT) method was employed to model flow cell experiments that measured transport of engineered nanoparticles (ENPs) in a reactive porous medium. The experiments involved a water‐saturated medium containing negatively charged, polyacrylamide beads, resembling many natural soils and aquifer materials, and having the same refraction index as water. Negatively and positively charged ENPs were injected into a uniform flow field in a 3‐D horizontal flow cell, and the spatial and temporal concentrations of the evolving ENP plumes were obtained via image analysis. As a benchmark, and to calibrate the model, Congo red tracer was employed in 1‐D column and 3‐D flow cell experiments, containing the same beads. Negatively charged Au and Ag ENPs demonstrated migration patterns resembling those of the tracer but were slightly more dispersive; the transport was well represented by the CTRW‐PT model. In contrast, positively charged AgNPs displayed an unusual behavior: establishment of an initial plume of essentially immobilized ENPs, followed by development of a secondary, freely migrating plume. The mobile plume was found to contain ENPs that, with aging, exhibited aggregation and charge inversion, becoming negatively charged and mobile. In this case, the CTRW‐PT model was modified to include a probabilistic law for particle immobilization, to account for the decreasing tendency (over distance and time) of the positively charged AgNPs to attach to the porous medium. The agreement between experimental results and modeling suggests that the CTRW‐PT framework can account for the non‐Fickian and surface‐charge‐dependent transport and aging exhibited by ENPs in porous media.

AbstractAn unprecedented palladium(II)‐catalyzed biomimetic aliphatic acyl (‐COR) group transfer was observed from acyl‐α‐peroxycoumarins to the ortho CH sites of directing arenes. Here, the CH activation is associated with a concomitant acyl group transfer via a Pd(II)‐catalyzed, redox‐neutral process. While methods for ortho aroylation (‐COAr) are well documented ortho acylation (‐COR) processes are scarce, hence the present redox‐neutral method is most ideal for o‐acylation of directing substrates.magnified image
Stereoselective Koenigs–Knorr Glycosylation Catalyzed by Urea
Authors: Sun Lifeng , Wu Xiaowei , Xiong De‐Cai , Ye Xin‐Shan 
Published: May 2016

AbstractA stereoselective Koenigs–Knorr glycosylation reaction under the catalysis of urea is described. This method is characterized by urea‐mediated hydrogen‐bond activation and subsequent glycosylation with glycosyl chlorides or bromides. Excellent yields and high anomeric selectivity can be achieved in most cases. Moreover, the low α‐stereoselectivity of glycosylations observed when using perbenzylated glucosyl donors can be greatly improved by the addition of tri‐(2,4,6‐trimethoxyphenyl)phosphine (TTMPP).

AbstractAdvanced tools for cell imaging are of great interest for the detection, localization, and quantification of molecular biomarkers of cancer or infection. We describe a novel photopolymerization method to coat quantum dots (QDs) with polymer shells, in particular, molecularly imprinted polymers (MIPs), by using the visible light emitted from QDs excited by UV light. Fluorescent core–shell particles specifically recognizing glucuronic acid (GlcA) or N‐acetylneuraminic acid (NANA) were prepared. Simultaneous multiplexed labeling of human keratinocytes with green QDs conjugated with MIP‐GlcA and red QDs conjugated with MIP‐NANA was demonstrated by fluorescence imaging. The specificity of binding was verified with a non‐imprinted control polymer and by enzymatic cleavage of the terminal GlcA and NANA moieties. The coating strategy is potentially a generic method for the functionalization of QDs to address a much wider range of biocompatibility and biorecognition issues.
