Published: October 2018

Human activities, especially dam construction, have changed the nutrient cycle process at the basin scale. Reservoirs often act as a sink in the basin and more nutrients are retained due to sedimentation, which induces the eutrophication of the surface water system. This paper proposes an integrated methodology to analyze the total nitrogen (TN) accumulation in a drinking water reservoir, based on the soil and water assessment tool (SWAT) model driven by the China Meteorological Assimilation Driving Datasets for the SWAT model (CMADS). The results show that the CMADS could be applied to drive the SWAT model in Northeast China. The dynamic process of TN accumulation indicates that the distribution of TN inputted into the reservoir fluctuated with the dry and wet seasons from 2009–2016, which was mainly governed by the amount of runoff. The annual average TN input and output fluxes of the Biliuhe reservoir were 274.41 × 104 kg and 217.14 × 104 kg, which meant that 19.76% of the TN input accumulated in the reservoir. Higher TN accumulation in the reservoir did not correspond to a higher TN load, due to the influence of flood discharge and the water supply. Interestingly, a higher TN accumulation efficiency was observed in normal hydrological years, because the water source reservoir always stores most of the water input for future multiple uses but rarely discharges surplus water. The non-point sources from fertilizer and atmospheric deposition and soils constituted the highest proportion of the TN input, accounting for 35.15%, 30.15%, and 27.72% of the average input. The DBWD (Dahuofang reservoir to Biliuhe reservoir water diversion) project diverted 32.03 × 104 kg year−1 TN to the Biliuhe reservoir in 2015–2016, accounting for 14.05% of the total annual input. The discharge output and the BDWD (Biliuhe reservoir to Dalian city water diversion) project output accounted for 48.75% and 47.74%, respectively. The effects of inter-basin water diversion projects should be of great concern in drinking water source water system management. There was a rising trend of TN level in the Biliuhe reservoir, which increases the eutrophication risk of the aquatic ecosystem. The TN accumulated in the sediment contributed to a large proportion of the TN accumulated in the reservoir. In addition to decreasing the non-point source nitrogen input from the upper basin, discharging anoxic waters and sediment with a high nitrogen concentration through the bottom hole of the dam could alleviate the nitrogen pollution in the Biliuhe reservoir.

Published: October 2018

Due to the uneven distribution of water resources in time and space, the problem of water shortage has become increasingly serious in some areas. To optimize use of water resources, it is urgent to establish multi-objective models and apply effective optimization algorithms to guide reservoir management. This study proposed a model of multi-objective optimization for reservoir operation (MORO) with the objectives of maximizing water diversion and power generation. The multi-objective evolutionary algorithm based on decomposition with adaptive weight vector adjustment (MOEA/D-AWA) was applied to solve the MORO problem. In addition, the performance of the MOEA/D-AWA was compared with two other algorithms based on the hyper-volume index. Huangjinxia reservoir, which is located in Shaanxi, China, was selected as the case study. The results show that: (1) the proposed model is effective and reasonable in theory; (2) the optimization results obtained by MOEA/D-AWA demonstrate this algorithm can be applied to the MORO problem, providing a set of evenly distributed non-dominated solutions; and (3) water diversion and power generation are indeed contradictory objectives. The MORO strategy can be used to efficiently utilize water resources, improve the comprehensive benefits of reservoirs, and provide decision support for actual reservoir operation.

Published: October 2018

We examined the food preference of Chinese mitten crabs, Eriocheir sinensis (H. Milne Edwards, 1853), under food shortage, habitat choice in the presence of predators, and cannibalistic behavior by comparing their response to the popular culture plant Elodea nuttallii and the structurally more complex Myriophyllum verticillatum L. in a series of mesocosm experiments. Mitten crabs were found to consume and thus reduce the biomass of Elodea, whereas no negative impact on Myriophyllum biomass was recorded. In the absence of adult crabs, juveniles preferred to settle in Elodea habitats (appearance frequency among the plants: 64.2 ± 5.9%) but selected for Myriophyllum instead when adult crabs were present (appearance frequency among the plants: 59.5 ± 4.9%). The mortality rate of mitten crabs in the absence of plant shelter was higher under food shortage, primarily due to cannibalism. The proportion of molting crabs dying in the structurally more complex Myriophyllum habitats was significantly lower than in the less complex Elodea habitats, indicating that Myriophyllum provides better protection from cannibalistic behavior, likely due to its structurally more complex canopy. Stable isotope analyses of crab samples revealed a trophic shift in both δ13C and δ15N (Δδ13C: 2.2–4.0‰; Δδ15N: 1.5–2.8‰) during the experimental period. Significant positive correlations between body mass and δ13C and δ15N were recorded, suggesting that cannibalistic feeding might further increase crab growth and lead to ontogenetic increases in trophic position with increasing size. Our study overall demonstrates that a combination of submerged aquatic vegetation functioning as a highly suitable food with other less palatable plant species acting as efficient refuges against predators may be the optimal method of plant stocking in mitten crab aquacultures to ensure both high crab growth and a high survival rate.
An Optical Study of Two VY Sculptoris-type Cataclysmic Binary Stars: V704 And and RX J2338+431
Authors: Weil Kathryn E. , Thorstensen John R. , Haberl Frank
Published: October 2018

We report observations of the known cataclysmic variable star (CV) V704 And, and also confirm that the optical counterpart of the ROSAT Galactic Plane Survey source RX J2338+431 is a heretofore-neglected CV. Photometric and spectroscopic observations from MDM Observatory show both systems to be nova-like variables that exhibit dips of 4–5 mag from their mean brightnesses, establishing them as members of the VY Scl subclass. From high-state emission-line radial velocities, we determine orbital periods of 0.151424(3) days (3.63 hr) for V704 And and 0.130400 (1) days (3.13 hr) for RX J2338+431. In V704 And, we find that the Hα emission-line measures cluster into distinct regions on a plot of equivalent width versus full width at half-maximum, which evidently correspond to high, intermediate, and low photometric states. This allows us to assign spectra to photometric states when contemporaneous photometry is not available, an apparently novel method that may be useful in studies of other novalikes. Our low-state spectra of RX J2338+431 show features of an M-type secondary star, from which we estimate a distance of 890 ± 200 pc, in good agreement with the Gaia DR2 parallax.

We present Atacama Large Millimeter/submillimeter Array observations of multiple protostar systems in the Perseus molecular cloud, previously detected by the Karl G. Jansky Very Large Array. We observe 17 close (<600 au separation) multiple systems at 1.3 mm in continuum and five molecular lines (i.e., 12CO, C18O, 13CO, H2CO, SO) to characterize the circum-multiple environments in which these systems are forming. We detect at least one component in the continuum for the 17 multiple systems. In three systems one companion is not detected, and for two systems the companions are unresolved at our observed resolution. We also detect circum-multiple dust emission toward eight out of nine Class 0 multiples. Circum-multiple dust emission is not detected toward any of the eight Class I multiples. Twelve systems are detected in the dense gas tracers toward their disks/inner envelopes. For these 12 systems, we use the dense gas observations to characterize their formation mechanism. The velocity gradients in the circum-multiple gas are clearly orthogonal to the outflow directions in eight out of the 12 systems, consistent with disk fragmentation. Moreover, only two systems with separations <200 au are inconsistent with disk fragmentation, in addition to the two widest systems (>500 au). Our results suggest that disk fragmentation via gravitational instability is an important formation mechanism for close multiple systems, but further statistics are needed to better determine the relative fraction formed via this method.
Solar Coronal Modeling by Path-conservative HLLEM Riemann Solver

Published: October 2018

In this paper, we employ a path-conservative HLLEM finite-volume method (FVM) to solve the solar wind magnetohydrodynamics (MHD) systems of extended generalized Lagrange multiplier (EGLM) formulation with Galilean invariance (G-EGLM MHD equations). The governing equations of single-fluid solar wind plasma MHD are advanced by using a one-step MUSCL-type time integration with the logarithmic spacetime reconstruction. The code is programmed in FORTRAN language with Message Passing Interface parallelization in spherical coordinates with a six-component grid system. Then, the large-scale solar coronal structures during Carrington rotations (CRs) 2048, 2069, 2097, and 2121 are simulated by inputting the line-of-sight magnetic field provided by the Global Oscillation Network Group (GONG). These four CRs belong to the declining, minimum, rising, and maximum phases of solar activity. Numerical results basically generate the observed characteristics of structured solar wind and thus show the code’s capability of simulating solar corona with complex magnetic topology.
Evolution of Circumbinary Protoplanetary Disks with Photoevaporative Winds Driven by External Far-ultraviolet Radiation

Published: October 2018

Lifetimes of protoplanetary disks (PPDs) are believed to be severely constrained by material-depleting mechanisms, including photoevaporative winds due to the host star radiation or external radiation sources. Most previous studies focused on exploring the role of the winds in the exposed PPDs with a single star; however, the evolution of the circumbinary disks with the photoevaporative winds driven by the host star radiation and external radiation sources deserves further exploration. In this study, we investigate the evolution of the circumbinary PPDs with the photoevaporative winds induced by the external far-ultraviolet radiation field. We show that this mass-loss process can significantly constrain properties of a circumbinary PPD, including its lifetime, mass, and radius. The lifetime of a circumbinary PPD, for instance, is found to be about a factor of two longer than a similar circumstellar disk, and this enhancement strongly depends on the viscosity parameter. But our model shows that viscosity dependence of the disk lifetime in the circumbinary case is more pronounced compared to the circumstellar case. We also show that dispersal of a circumbinary PPD occurs over a longer time as the disk temperature distribution becomes steeper. Our results also imply that a dead zone in a photoevaporative circumbinary PPD extends over a larger radial range in comparison to a circumstellar disk counterpart. We also show that our calculations are in agreement with the observed circumbinary PPDs orbiting equal-mass binaries.
Direction-finding Analysis of the 2012 July 6 Type II Solar Radio Burst at Low Frequencies
Authors: Mäkelä Pertti , Gopalswamy Nat , Akiyama Sachiko
Published: October 2018

The 2012 July 6 X1.1 flare at S13W59 and a halo coronal mass ejection (CME) with a space speed of ∼1900 km s−1 were associated with type III and type II radio bursts. The metric-to-decametric type II radio burst extended down to ∼5 MHz. Simultaneously, a slowly drifting feature with a harmonic structure was observed by Wind and Solar Terrestrial Relations Observatory radio receivers around and below 1 MHz, above the strong type III radio burst at lower frequencies. The radio direction-finding analysis of this lower-frequency interplanetary (IP) type II radio burst indicates that the radio source was located near the nose and possibly toward the southern flank of the CME-driven shock. These results provide an independent confirmation of the previous suggestions that when the metric and IP type II bursts are overlapping, the lower-frequency IP type II radio burst originates near the shock nose, whereas the source of the higher-frequency metric type II burst is closer to the Sun in the shock flank region. These results further support the idea that the coronal and IP type II bursts are produced by the same CME-driven shock.
Scattered Short Gamma-Ray Bursts as Electromagnetic Counterparts to Gravitational Waves and Implications of GW170817 and GRB 170817A

Published: October 2018

In the faint short gamma-ray burst sGRB 170817A followed by the gravitational waves (GWs) from a merger of two neutron stars (NSs) GW170817, the spectral peak energy is too high to explain only by canonical off-axis emission. We investigate the off-axis appearance of an sGRB prompt emission scattered by a cocoon, which is produced through the jet–merger–ejecta interaction, with either subrelativistic or mildly relativistic velocities. We show that the observed properties of sGRB 170817A, in particular the high peak energy, can be consistently explained by the Thomson-scattered emission with a typical sGRB jet, together with its canonical off-axis emission, supporting that an NS–NS merger is the origin of sGRBs. The scattering occurs at ≲1010–1012 cm not far from the central engine, implying the photospheric or internal shock origin of the sGRB prompt emission. The boundary between the jet and cocoon is sharp, which could be probed by future observations of off-axis afterglows. The scattering model predicts a distribution of the spectral peak energy that is similar to the observed one but with a cutoff around ∼MeV energy and its correlations with the luminosity, duration, and time lag from GWs, providing a way to distinguish it from alternative models.

We present a multiwavelength analysis based on archival radio, optical, and X-ray data of the complex radio source 3C 196.1, whose host is the brightest cluster galaxy of a z = 0.198 cluster. HST data show Hα+[N ii] emission aligned with the jet 8.4 GHz radio emission. An Hα+[N ii] filament coincides with the brightest X-ray emission, the northern hotspot. Analysis of the X-ray and radio images reveals cavities located at galactic and cluster scales. The galactic-scale cavity is almost devoid of 8.4 GHz radio emission and the southwestern Hα+[N ii] emission is bounded (in projection) by this cavity. The outer cavity is cospatial with the peak of 147 MHz radio emission, and hence we interpret this depression in X-ray surface brightness as being caused by a buoyantly rising bubble originating from an active galactic nuclei outburst ∼280 Myr ago. A Chandra snapshot observation allowed us to constrain the physical parameters of the cluster, which has a cool core with a low central temperature ∼2.8 keV, low central entropy index ∼13 keV cm2 and a short cooling time of ∼500 Myr, which is < 0.05 of the age of the universe at this redshift. By fitting jumps in the X-ray density, we found Mach numbers between 1.4 and 1.6, consistent with a shock origin. We also found compelling evidence of a past merger, indicated by a morphology reminiscent of gas sloshing in the X-ray residual image. Finally, we computed the pressures, enthalpies E

NGC 6791: A Probable Bulge Cluster without Multiple Populations*
Authors: Villanova Sandro , Carraro Giovanni , Geisler Doug , Monaco Lorenzo , Assmann Paulina
Published: October 2018

NGC 6791 is a unique stellar cluster, key to our understanding of both the multiple stellar population phenomenon and the evolution and assembly of the Galaxy. However, despite many investigations, its nature is still very controversial. Geisler et al. found evidence suggesting that it was the first open cluster to possess multiple populations, but several subsequent studies did not corroborate this. It has also been considered a member of the thin or thick disk or even the bulge, and either as an open or globular cluster or even the remnant of a dwarf galaxy. Here we present and discuss detailed abundances derived from high-resolution spectra obtained with UVES at VLT and HIRES at Keck of 17 evolved stars of this cluster. We obtained a mean [Fe/H] = +0.313 ± 0.005, in good agreement with recent estimates, and with no indication of star-to-star metallicity variation, as expected. We also did not find any variation in Na, in spite of having selected the very same stars as in Geisler et al., where an Na variation was claimed. This points to the presence of probable systematics in the lower-resolution spectra of this very high metallicity cluster analyzed in that work. In fact, we find no evidence for an intrinsic spread in any element, corroborating recent independent APOGEE data. The derived abundances indicate that NGC 6791 very likely formed in the Galactic bulge and that the proposed association with the thick disk is unlikely, despite its present Galactic location. We confirm the most recent hypothesis suggesting that the cluster could have formed in the bulge and radially migrated to its current location, which appears to be the best explanation for this intriguing object.

We report on the coexistence of powerful gas outflows observed in millimeter and X-ray data of the radio-loud narrow-line Seyfert 1 Galaxy IRAS 17020+4544. Thanks to the large collecting power of the Large Millimeter Telescope (LMT), a prominent line arising from the 12CO(1–0) transition was revealed in recent observations of this source. The complex profile is composed by a narrow double-peak line and a broad wing. While the double-peak structure may be arising in a disk of molecular material, the broad wing is interpreted as the signature of a massive outflow of molecular gas with an approximate bulk velocity of −660 km s−1. This molecular wind is likely associated to a multi-component X-ray ultra-fast outflow with velocities reaching up to ∼ 0.1c and column densities in the range 1021–23.9 cm−2 that was reported in the source prior to the LMT observations. The momentum load estimated in the two gas phases indicates that within the observational uncertainties the outflow is consistent with being propagating through the galaxy and sweeping up the gas while conserving its energy. This scenario, which has been often postulated as a viable mechanism of how active galactic nucleus (AGN) feedback takes place, has so far been observed only in ultraluminous infrared galaxy sources. IRAS 17020+4544 with bolometric and infrared luminosity, respectively, of 5 × 1044 erg s−1 and 1.05 × 1011

⊙ appears to be an example of AGN feedback in a NLSy1 Galaxy (a low power AGN). New proprietary multi-wavelength data recently obtained on this source will allow us to corroborate the proposed hypothesis.

We present the discovery of ASASSN-18ey (MAXI J1820+070), a new black hole low-mass X-ray binary (LMXB) discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN). A week after ASAS-SN discovered ASASSN-18ey as an optical transient, it was detected as an X-ray transient by MAXI/GCS. Here, we analyze ASAS-SN and Asteroid Terrestrial-impact Last Alert System pre-outburst optical light curves, finding evidence of intrinsic variability for several years prior to the outburst. While there was no long-term rise leading to the outburst, as has been seen in several other systems, the start of the outburst in the optical preceded that in the X-rays by 7.20 ± 0.97 days. We analyze the spectroscopic evolution of ASASSN-18ey from pre-maximum to >100 days post-maximum. The spectra of ASASSN-18ey exhibit broad, asymmetric, double-peaked Hα emission. The Bowen blend (λ ≈ 4650 Å) in the post-maximum spectra shows highly variable double-peaked profiles, likely arising from irradiation of the companion by the accretion disk, typical of low-mass X-ray binaries. The optical and X-ray luminosities of ASASSN-18ey are consistent with black hole low-mass X-ray binaries, both in outburst and quiescence.

Howard Gardner revolutionized the concept of intelligence with his Multiple Intelligences Theory. His vision was widely supported by the educational community, which considers different forms of learning and accessing knowledge. Despite its impact, there is still a lack of development of tools that can easily, practically and reliably evaluate multiple intelligences. This work describes the design, development, and piloting of TOI (Tree of Intelligences) software, a digital tool to evaluate multiple intelligences and perform interventions through video games. The aim of the study is to present the design of the TOI software and test its operation, analysing the distribution of the results game by game and checking whether there are differences according to gender or school year. A total of 372 primary school students participated, aged 5 to 9 years old (M=7.04, SD=.871), from three schools in Asturias and Madrid. The results show that 9 out of 10 games had a normal distribution and that there were no gender differences in most games, but there were differences in relation to the school year. We concluded that due to its operation and design TOI software has the potential be a suitable instrument for the evaluation and intervention of multiple intelligences.

The eGames business (online video games) in Spain generated more than 1.8 trillion euros in profits in 2016. Advertising is no stranger to the potential of this market, and brands study the best ways of approaching and adapting to the world of eGames. In this report, we analyze which the most effective advertising strategies for brands in the online video game world are. To do this, the players (eGamers) answered a 60 question survey that addressed issues such as playful habits, the viewing of advertisements in games, the purchase of advertised items and advertising in competitions. Korean and Spanish players answered the same questionnaire considering that South Korea has the most advanced video game industry in the world and Spain is the fourth European country in eGames and our subject of study. After the investigation, some of the most relevant results indicate that conventional online advertising does not attract the attention of gamers as consumers. We determined that the best strategy would be based on brand presence through products that are prescribed or used by professional gamers, since spectators, as they watch the games, also observe what elements and accessories the players use.

El negocio de los eGames (videojuegos online) en España ha conseguido más de 1,8 billones de euros de beneficio en el año 2016. La publicidad no es ajena al potencial de este mercado y las marcas estudian cuáles son las mejores formas de acercarse y adaptarse al entorno de los eGames. En el presente trabajo se analizan las estrategias publicitarias más eficaces para las marcas en el mundo de los videojuegos en red. Para ello, se han investigado a los jugadores (eGamers) a través de una encuesta de 60 preguntas que abordaban cuestiones como hábitos lúdicos, visionado de publicidad en los juegos, compra de artículos anunciados o publicidad en competiciones. El mismo cuestionario se ha realizado tanto a jugadores coreanos, ya que la industria de los videojuegos en Corea del Sur es la más avanzada del mundo, como a jugadores españoles, al ser España el cuarto país europeo en eGames y ser nuestro objeto de estudio. Tras la investigación, algunos de los resultados más relevantes indican que la publicidad online convencional no llama la atención a los consumidores «gamers» y se determina que la mejor estrategia se basaría en la presencia de marca a través de productos prescritos o utilizados por los «gamers» profesionales, ya que los espectadores, a la vez que ven las partidas, observan qué elementos usan los jugadores.

The purpose of this study was to evaluate the short-term clinical and radiographic outcomes of humeral hemiarthroplasty and concentric glenoid reaming (“ream and run” procedure) and to compare the outcomes with those of total shoulder arthroplasty (TSA) for glenohumeral arthritis. Patients with glenohumeral arthritis who underwent the ream and run procedure with a minimum follow-up of 2 years were retrospectively reviewed. The primary outcome was revision to TSA. Secondary outcome measures included functional outcome scores, range of motion, and radiographic assessment. The outcome measures were compared with those of age- and sex-matched control patients who underwent anatomic TSA during the study period. One patient in the ream and run group required revision to TSA 14 months after the surgery because of excessive shoulder pain. There were significant improvements in the postoperative outcome scores and range of motion and external rotation in the ream and run group. Postoperative radiographs showed concentric glenoids without posterior subluxation in all except 1 shoulder. The outcome measures in the ream and run group were similar to those in the TSA control group except for active forward elevation and external rotation. The ream and run procedure provides improved pain relief and shoulder function at short-term follow-up for patients with shoulder arthritis. [

There are several surgical options for addressing Paprosky type III acetabular defects during revision total hip arthroplasty. In physiologically young and active patients, using structural bone graft to restore bone defects and provide adequate initial support for the revision acetabular component is one such option. This study reports the mid-term results of using a structural allograft accompanied by a trabecular metal-coated hemispherical cup for Paprosky type III defects. A retrospective analysis was performed of the data collected for 20 consecutive hips in 20 patients (mean age, 56.2 years; range, 43–68 years) with minimum 3-year follow-up (mean, 5.4 years; range, 3.3–10.3 years) who had a structural allograft accompanied by a trabecular metal-coated hemispherical cup for Paprosky type III defects. Only 1 hip had cup migration, which was less than 3 mm in vertical and less than 5° in inclination and recognized as loosening without symptoms. All grafts showed good incorporation with trabecular bridging over the graft and host bone.

Malignant tumors of the scapula are rare, and limb salvage surgery after tumor resection is challenging. The authors present a series of 6 patients who were treated by total scapulectomy and reconstruction with a custom-made scapular prosthesis and a constrained reverse shoulder arthroplasty. Postoperative oncologic and functional outcomes were assessed. The mean follow-up was 37 months (range, 9–84 months). Clear surgical margins were achieved in all patients. At the last follow-up, 4 patients showed no evidence of disease and 2 had died of systemic metastatic disease. Although shoulder function was limited, all shoulders were painless and stable and the patients retained satisfactory hand, wrist, and elbow function. [

Visual Impairment and Eye Disease Among Children of Migrant Farmworkers
Authors: Soares Rebecca Russ , Rothschild Michael , Haddad Danny , Lenhart Phoebe
Published: October 2018

Purpose:

To determine the prevalence of reduced visual acuity and ocular disease in the children of migrant farmworkers in Georgia.

Methods:

A retrospective chart review of data acquired by a vision screening was performed on 156 Haitian and Hispanic children of migrant farmworkers attending a summer school in Georgia. Reduced visual acuity at presentation was analyzed and stratified by ethnicity, type of ocular disease, and immediate resolution with refractive correction.

Results:

The authors found that 20% of migrant farmworker children have a high prevalence of reduced visual acuity in the worse eye. Of those with worse-eye reduced visual acuity, 83% had uncorrected refractive error. The prevalence of uncorrected refractive error from astigmatism and high astigmatism was significantly higher among Hispanics than Haitians. The prevalence of amblyopia suspects among migrant farmworker children was 3%. Of the amblyopia suspects, 80% were anisometropic.

Conclusions:

Children of migrant farmworkers in Georgia have a higher rate of reduced visual acuity, largely from uncorrected refractive error, when compared to other Hispanic and African American children in the United States with a prevalence more aligned to children in Asian and Latin American countries than school children in the United States. This illustrates the need for improved access to screening and care in this vulnerable population.

Using biometric fingerprint technique for identity verification has become a primordial due  to the Reduced costs of implementation,  maturity of this  technology in the market  and the ease of use. Many implementations exist using this technique , however, these systems are hard coupled with the environment in which they were developed and the hardware used to capture biometric data. Consequently,  the interoperability issue is hard present in case of changing the environment or using new fingerprint reader. In this paper, we propose a new architecture to solve this problem by dividing the main biometric application to layers based on a flexible communication between components and supporting heterogeneous platforms and  biometric readers.

Lire l’humain
Authors: Trouvé Alain

Confronter les œuvres d’Aragon et de Ponge revêt des enjeux littéraires, politiques, anthropologiques. Ces deux figures des lettres du xxe siècle, liées aux avant-gardes, de Dada et du surréalisme (Aragon) à Tel Quel (Ponge), ont partagé fugitivement, durant la période de la Résistance, l’engagement communiste. Leur divergence croissante dans l’après-guerre et l’inversion relative du prestige symbolique accordé à chacun constituent un objet d’investigation dont l’intérêt dépasse les cas respectifs.L’enquête et la réflexion proposées dans ce livre s’attachent à situer les pratiques esthétiques selon un parcours en six parties qui associe à l’histoire littéraire les outils de la théorie de la lecture. À l’intertextualité, désormais classique, est ajoutée la notion d’arrière-texte (aux connotations aragoniennes), qui met au jour certains ressorts cachés de l’écriture-lecture. Il s’agit aussi, dans un esprit cette fois proche du lexique pongien, de prolonger une parole d’écrivain-lecteur en une contre-parole de lecteur-écrivant.S’immiscer dans ce dialogue à distance, ce n’est pas seulement essayer de comprendre ce qui différencie et relie en profondeur les œuvres, c’est aussi, peut-être, par l’oscillation entre ces deux régimes de lecture littéraire, tenter d’élaborer, pour son propre compte, une pensée de l’humain.

The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls) aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT-26) and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

Published: October 2018

The objective of the study was to analyze the age marker in males and females as a predictor of the absence of frailty syndrome in the elderly. This was a cross-sectional study with 624 individuals. Receiver Operating Characteristic (ROC) curves were constructed and compared to areas of age, gender and absence of frailty. Cut-off points for age (years) were established to predict the absence of frailty (95% CI). The largest areas under the ROC curve for age were found for females. It was observed that the age of 72 years (women) or 67 (men) were the best cut-off points for predicting the absence of frailty. The age marker can serve as an important indicator in selecting priority groups for certain interventions.

The State Program of fluoride mouthwashes for caries control was established in 1980 in elementary schools of Paraná State covering children 7-11 years old. Knowing the importance of removing bacterial plaque to reach the maximum desired effect of prevention, this study aimed to evaluate the Simplified Oral Hygiene Index, before applying the solution of Sodium Fluoride (NaF; 0.2%) in children from an elementary school in the city of Nova Aurora, Paraná State, by using disclosing dental plaque. This is a quantitative research, descriptive and exploratory whose data were obtained through a specific form, with 61 children and analyzed using descriptive statistics with distribution of absolute and percentage frequencies. Most children (60%) showed the worst results - regular and bad - with presence of plaque and risk of dental caries. Therefore, we should establish a prevention program in oral health that must involve parents and students. This program should be developed by health professionals inside the school, explaining about the etiologic factors, causes and consequences of plaque, the techniques of cleaning and maintenance of hygiene instruments, and the risks of the lack of proper hygiene in the oral cavity.
TAOK3 Regulates Canonical TCR Signaling by Preventing Early SHP-1–Mediated Inactivation of LCK
Authors: Ormonde João V. S. , Li Zhigang , Stegen Camille , Madrenas Joaquín
Published: October 2018

Activation of LCK is required for canonical TCR signaling leading to T cell responses. LCK activation also initiates a negative feedback loop mediated by the phosphatase SHP-1 that turns off TCR signaling. In this article, we report that the thousand-and-one amino acid kinase 3 (TAOK3) is a key regulator of this feedback. TAOK3 is a serine/threonine kinase expressed in many different cell types including T cells. TAOK3-deficient human T cells had impaired LCK-dependent TCR signaling resulting in a defect in IL-2 response to canonical TCR signaling but not to bacterial superantigens, which use an LCK-independent pathway. This impairment was associated with enhanced interaction of LCK with SHP-1 after TCR engagement and rapid termination of TCR signals, a defect corrected by TAOK3 reconstitution. Thus, TAOK3 is a positive regulator of TCR signaling by preventing premature SHP-1–mediated inactivation of LCK. This mechanism may also regulate signaling by other Src family kinase-dependent receptors.
