Published: September 2017

El objetivo de esta investigación fue evaluar la supervivencia y crecimiento de una plantación de Pinus greggii establecida en 2003 en un terreno (2.1 ha) con suelo degradado y escasa precipitación. En especial se evaluó el efecto de las características edafológicas del sitio en el crecimiento de la plantación. Se registraron también la cobertura, la regeneración natural y el material combustible. Para esto, se establecieron 9 sitios circulares de 1/10 ha, en tres bloques de acuerdo a la pendiente del terreno. La supervivencia promedio fue de 91%, con mejores porcentajes en los bloques medio e inferior de la parcela. La altura, diámetro y volumen arrojaron diferencias significativas entre los sitios y bloques, los mayores valores e incrementos se registraron en los árboles de los sitios inferiores del terreno que muestran mayor fertilidad. En promedio la altura fue de 9.4 m, el diámetro de 14.4 cm y el volumen 60.2 m3 r.t.a. ha-1 (metro cúbico de madera en rollo total del árbol en una superficie de 1 ha). En las partes altas del terreno se registró la menor cobertura vegetal (9.6% del suelo), favoreciendo con esto la presencia de elementos vegetales propios de sitios con alta luminosidad, como los magueyes, registrándose en promedio 400 individuos por hectárea. Respecto al material combustible, solo se registró en los sitios inferiores y medios, siendo la biomasa combustible ≥ 5 cm de diámetro la de mayor cantidad (69.2 kg ha-1). Dado que este material se encuentra disperso, no pone en riesgo de incendios a la plantación. Se recomienda realizar preaclareos y podas en los árboles que quedaran hasta el final del turno. Estas acciones reducirán la competencia y aumentaran la calidad de la madera, además de mejorar las condiciones edáficas del sitio mediante la incorporación del material vegetal al suelo.

Authors: Vega Gámez Marta Inés 
Published: September 2017

<p>Esta investigación busca caracterizar el desarrollo motor y la cultura somática wayuu considerando el cuerpo como hecho bio-psico-social. En este sentido, ha sido necesario establecer también de qué manera los wayuu estimulan el desarrollo motor de los niños con el fin de prepararlos para la ejecución de labores que garanticen la subsistencia (pesca, cacería, pastoreo, agricultura, elaboración de artesanías), el ocio y la recreación (juegos autóctonos y apropiados), la reproducción de la cultura (danza) y el fortalecimiento de la identidad. Se presenta el contexto geográfico y cultural de los indígenas wayuu que habitan en el departamento de La Guajira - Colombia. Los referentes teóricos están fundamentados en los planteamientos de la antropología del cuerpo, los conceptos de cultura somática, etnomotricidad, desarrollo motor y expresiones motrices. La metodología está basada en el enfoque cualitativo, el método etnográfico y la aplicación de técnicas como la entrevista y la observación participante. Los resultados presentan las diferentes etapas de desarrollo definidas por los wayuu y la caracterización del desarrollo motriz en cada una de ellas.<br />Así mismo, se señala la importancia de algunas actividades cotidiana para el desarrollo de habilidades específicas. La cultura somática y el desarrollo motor de los wayuu deben abordarse desde una perspectiva holística y su fomento no solo debe contemplar la dimensión física del individuo sino también lo cognitivo y cultural.</p>

Premise of the study:Chloroplast primers were developed from genomic data for the taxonomically challenging genus Castilleja. We further tested the broader utility of these primers across Orobanchaceae, identifying a core set of chloroplast primers amplifying across the clade.Methods and Results:Using a combination of three low‐coverage Castilleja genomes and sequence data from 12 Castilleja plastomes, 76 primer combinations were specifically designed and tested for Castilleja. The primers targeted the most variable portions of the plastome and were validated for their applicability across the clade. Of these, 38 primer combinations were subsequently evaluated in silico and then validated across other major clades in Orobanchaceae.Conclusions:These results demonstrate the utility of these primers, not only across Castilleja, but for other clades in Orobanchaceae—particularly hemiparasitic lineages—and will contribute to future phylogenetic studies of this important clade of parasitic plants.
Measuring the Growth Rate of Structure with Type IA Supernovae from LSST

Published: September 2017

Abstract
We investigate the peculiar motions of galaxies up to z = 0.5 using Type Ia supernovae (SNe Ia) from the Large Synoptic Survey Telescope (LSST) and predict the subsequent constraints on the growth rate of structure. We consider two cases. Our first is based on measurements of the volumetric SNe Ia rate and assumes we can obtain spectroscopic redshifts and light curves for varying fractions of objects that are detected pre-peak luminosity by LSST (some of which may be obtained by LSST itself, and others that would require additional follow-up observations). We find that these measurements could produce growth rate constraints at

that significantly outperform those found using Redshift Space Distortions (RSD) with DESI or 4MOST, even though there are

fewer objects. For our second case, we use semi-analytic simulations and a prescription for the SNe Ia rate as a function of stellar mass and star-formation rate to predict the number of LSST SNe IA whose host redshifts may already have been obtained with the Taipan+WALLABY surveys or with a future multi-object spectroscopic survey. We find ∼18,000 and ∼160,000 SNe Ia with host redshifts for these cases, respectively. While this is only a fraction of the total LSST-detected SNe Ia, they could be used to significantly augment and improve the growth rate constraints compared to only RSD. Ultimately, we find that combining LSST SNe Ia with large numbers of galaxy redshifts will provide the most powerful probe of large-scale gravity in the

regime over the coming decades.
A Model of the Pulsating Extremely Low-mass White Dwarf Precursor WASP 0247–25B

Published: September 2017

Abstract
We present an analysis of the evolutionary and pulsation properties of the extremely low-mass white dwarf precursor (B) component of the double-lined eclipsing system WASP 0247−25. Given that the fundamental parameters of that star have been obtained previously at a unique level of precision, WASP 0247−25B represents the ideal case for testing evolutionary models of this newly found category of pulsators. Taking into account the known constraints on the mass, orbital period, effective temperature, surface gravity, and atmospheric composition, we present a model that is compatible with these constraints and show pulsation modes that have periods very close to the observed values. Importantly, these modes are predicted to be excited. Although the overall consistency remains perfectible, the observable properties of WASP 0247−25B are closely reproduced. A key ingredient of our binary evolutionary models is represented by rotational mixing as the main competitor against gravitational settling. Depending on assumptions made about the values of the degree index ℓ for the observed pulsation modes, we found three possible seismic solutions. We discuss two tests, rotational splitting and multicolor photometry, that should readily identify the modes and discriminate between these solutions. However, this will require improved temporal resolution and higher S/N observations, which are currently unavailable.
Le Brésil et ses Indiens : une réconciliation impossible ?
Authors: Le Tourneau François-Michel 
Published: September 2017

En ouvrant de larges droits fonciers aux Amérindiens, la Constitution de 1988 avait semblé avancer dans le sens de la réparation du préjudice historique représenté par la dépossession territoriale des Amérindiens. Trente ans plus tard, force est de constater que la réconciliation attendue n’a pas eu lieu. Le moteur principal de la dispute est sans aucun doute d’ordre spatial. Les Amérindiens disposent en théorie aujourd’hui d’un usufruit exclusif sur une portion considérable du territoire brésilien (environ 13,7 %) mais le balancier semble avoir effectué son mouvement en sens inverse depuis une dizaine d’années. Pour faire le point sur cette question et sur les enjeux qui lui sont liés, cet article propose tout d’abord un rapide panorama historique de la manière dont la question amérindienne a été considérée au Brésil depuis la colonisation portugaise jusqu’aux avancées de la fin du XXe siècle, en nous focalisant principalement sur la question des territoires. Dans un deuxième temps, nous montrerons comment la Constitution de 1988 a permis la consolidation d’un patrimoine foncier très important, alors que la population amérindienne demeure ultra-minoritaire. La dernière partie fait le point sur la situation actuelle en essayant de montrer comment l’inflexion dans un sens défavorable aux droits fonciers des Amérindiens est patente depuis plus de dix ans et combien la situation actuelle met à l’épreuve les protections dont ils bénéficient. En conclusion, on s’interroge sur les scénarios possibles pour les prochaines années.
The Brazilian National Policy for Regional Development and the RIDE-DF Management opposite the Governance vs Brasília’s Metropolitan Area
Authors: Santos Renata Callaça Gadioli dos , Bessa Luiz Fernando de Macedo , Lúcio Magda de Lima 
Published: September 2017

La politique nationale brésilienne pour le développement régional - PNDR a été créée par le décret 6047/2007. Cependant, de nombreux gestionnaires publics affirment qu'elle n'a pas encore atteint un statut de politique d'État ou un consensus politique ou fédéral capable de promouvoir une croissance non fragmentée et équilibrée des régions. La discussion porte maintenant sur l'institutionnalisation d'une nouvelle politique, le PNDR II, qui continue de réduire les inégalités régionales et cherche à remédier aux insuffisances de la première proposition. Malgré la proposition de mise à jour de la législation en question, le territoire métropolitain de Brasilia, également défini par la législation fédérale et appelé RIDE DF et Entorno - Région intégrée de développement du District fédéral et de ses environs, est identifié comme un domaine prioritaire de planification et de gestion, mais sa gouvernance métropolitaine continue de créer des conflits et de maintenir l'inégalité dans ses zones périphériques. Pour contribuer au débat sur la portée possible du PNDR dans la gestion d'une ville aussi importante et complexe, qui est aussi la capitale fédérale, et ses régions métropolitaines respectives, nous proposons une analyse théorique et méthodologique du modèle de gouvernance urbaine. Tout au long de l'analyse, nous démontrerons la relation entre PNDR I et II et la - RIDE-DF et Entorno, une proposition de gestion territoriale du District fédéral du Brésil et de son agglomération urbaine. Dans ce contexte, l'objectif de cet article est d'analyser les instruments proposés par la nouvelle politique nationale pour le développement régional face au défi d'une meilleure gouvernance régionale ou métropolitaine pour le RIDE DF et Entorno.
Une revue des développements récents des vaccins de la fièvre aphteuse
Authors: Lombard Michel 
Published: September 2017

Depuis l’interdiction de la vaccination obligatoire contre la Fièvre Aphteuse en France (1991), les développements de la technologie vaccinale ont été si divers que les vaccins aujourd’hui disponibles sont plus avantageux que par le passé ; les vaccins avaient alors comme adjuvants l’ hydroxyde d’aluminium et la saponine, avec une dose de 5 ml.
Les vaccins modernes sont hautement purifiés, les adjuvants sont meilleurs, l’innocuité plus élevée pour un usage plus large chez les espèces sensibles. H est possible de conserver un million de doses d’antigènes fortement congelés d’avance, sous forme très concentrée et purifiée ; ce qui rend la vaccination immédiate plus facile, car un grand nombre de doses peut être préparé dans un court laps de temps (4 à 7 jours).
L’élimination des principales protéines non structurelles au cours de la purification donne aux vaccins modernes la propriété intéressante de ne plus interférer avec la surveillance sérologique effectuée dans le but d’identifier des groupes d’animaux infectés ou porteurs au moyen de protéines marqueurs de l’infection Fièvre Aphteuse.
Des évidences scientifiques supplémentaires tirées d’expérimentations démontrent que la vaccination avec des vaccins à fort potentiel peut prévenir l’excrétion du virus et l’état de porteur dans les populations animales vaccinées, ce qui contribue à stopper rapidement l’extension de la maladie.
Au début du présent siècle, les vétérinaires et les Autorités ont désormais l’occasion de sélectionner, afin de contrôler les épidémies de Fièvre Aphteuse, d’autres mesures que l’abattage en masse.
Carbon degradation in agricultural soils flooded with seawater after managed coastal realignment
Authors: Sjøgaard Kamilla S. , Treusch Alexander H. , Valdemarsen Thomas B. 
Published: September 2017

Abstract. Permanent flooding of low-lying coastal areas is a growing threat due to climate change and related sea-level rise. An increasingly common solution to protect coastal areas lying below sea level is intentional flooding by "managed coastal realignment". However, the biogeochemical implications of flooding agricultural soils with seawater are still not well understood. We conducted a 1-year mesocosm experiment to investigate microbial carbon degradation processes in soils flooded with seawater. Agricultural soils were sampled on the northern coast of the island Fyn (Denmark) at Gyldensteen Strand, an area that was subsequently flooded in a coastal realignment project. We found rapid carbon degradation to TCO2 1 day after experimental flooding and onwards and microbial sulfate reduction established quickly as an important mineralization pathway. Nevertheless, no free sulfide was observed as it precipitated as Fe–S compounds with Fe acting as a natural buffer, preventing toxic effects of free sulfide in soils flooded with seawater. Organic carbon degradation decreased significantly after 6 months, indicating that most of the soil organic carbon was refractory towards microbial degradation under the anoxic conditions created in the soil after flooding. During the experiment only 6–7 % of the initial soil organic carbon pools were degraded. On this basis we suggest that most of the organic carbon present in coastal soils exposed to flooding through sea-level rise or managed coastal realignment will be permanently preserved.

Published: September 2017

Purpose To evaluate the performance of various tests with automated and subjective evaluation for primary diagnostics of glaucoma in a normal clinical setting. Methods Subjects referred because of suspicion of glaucoma were recruited. All subjects had full ophthalmologic evaluation with stereophotography of the optic nerve head (ONH), red-free retinal nerve fiber layer (RNFL) photography, scanning laser polarimetry (SLP), optical coherence tomography (OCT), and standard automated perimetry (SAP). Analysis of all results was made jointly by 5 glaucoma specialists, with a consensus for each eye as healthy, glaucomatous, or glaucoma suspect. Results from each method were evaluated against this consensus, followed by a subjective evaluation of each method by a glaucoma specialist, comparing this with automated classification by the devices. Results Of the 101 subjects and 202 eyes examined, 23 eyes were by consensus glaucomatous, and 23 were glaucoma suspect. Sensitivity was best with ONH photos and worst with SAP, while SLP had a better sensitivity but poorer specificity than did RNFL photographs and OCT. Subjective evaluation of SLP, OCT, and SAP data gave better sensitivity and specificity than did classification by numeric values from the devices only, with OCT performing better in automatic classification than did SLP or SAP. Conclusions None of the current methods is superior to others in diagnosing glaucoma, and the accuracy of automated tests was better when subjectively evaluated by an experienced ophthalmologist. Diagnosis of glaucoma should be based on a combination of test results interpreted by a clinician.

Published: September 2017

This paper introduces a new resource designed to facilitate the quantitative investigation of syntactic variation in spoken language from a comparative perspective. The datasets comprise homogeneously annotated collections of “interchangeable” (i.e. competing) genitive and dative variants in four varieties of English: American English, British English, Canadian English, and New Zealand English. To showcase the empirical potential of the data source, we present a suggestive analysis that investigates the extent to which the probabilistic grammar of genitive and dative variant choice differs across varieties. The statistical analysis reveals that while there are a number of subtle probabilistic contrasts between the regional varieties under study, there is overall a striking degree of cross-varietal homogeneity. We conclude by outlining directions for future research. This article is part of the Special Collection: Probabilistic grammars: Syntactic variation in a comparative perspective
Collective Ion-Pair Single-Drop Microextraction Attenuated Total Reflectance Fourier Transform Infrared Spectroscopic Determination of Perchlorate in Bioenvironmental Samples
Authors: Chandrawanshi Swati , Verma Santosh K , Deb Manas K 
Published: September 2017

Abstract
Perchlorate (ClO4−) is an environmental pollutant that affects human health. Perchlorate acts as a competitive inhibitor of iodine uptake in the thyroid gland (sodium–iodide symporter inhibitor); thus, its determination is important for public health concerns. Water and milk constitute a significant portion of the human diet. Because regular intake leads to an increase in perchlorate concentration in the human body, the estimation of perchlorate is of great concern. In this work, ion-pair single-drop microextraction (SDME) combined with attenuated total reflectance (ATR)-FTIR spectroscopy has been developed for the determination of perchlorate in bioenvironmental (soil, water, dairy milk, breast milk, and urine) samples. Perchlorate was extracted in a single drop of methyl isobutyl ketone as an - with the cationic surfactant cetyltrimethylammonuim bromide under optimized conditions. The strongest IR peak (at 1076 cm−1) was selected for the quantification of perchlorate among three observed vibrational peaks. Eight calibration curves for different concentration ranges of perchlorate were prepared, and excellent linearity was observed for absorbance and peak area in the range of 0.03–100 ng/mL perchlorate, with r values of 0.977 and 0.976, respectively. The RSDs (n = 8) for the perchlorate concentration ranges of 0.03–100, 0.03–0.5, 0.5–10, and 10–100 ng/mL were in the range of 1.9–2.7% for the above calibration curves. The LOD and LOQ in the present work were 0.003 and 0.02 ng/mL, respectively. The extracted microdrop was analyzed directly by ATR-FTIR spectroscopy. The parameters affecting SDME, i.e, effect of pH, stirring rate, reagent concentration, microdrop volume, and extraction time, were optimized, and the role of foreign species was also investigated. F- and t-tests were performed to check the analytical QA of the method. A noteworthy feature of the reported method is the noninterference of any of the associated ions. The results were compared with those of the ion chromatography MS method, and a high degree of acceptability was found. The method was successfully applied for the determination of perchlorate in bioenvironmental samples.
Correlation-Regression Analysis for Understanding Dominant Height Projection Accuracy
Authors: Wang Mingliang , Kane Michael B , Zhao Dehai 
Published: September 2017

Abstract
Dominant height predictions tend to be less accurate with increasing projection intervals, a common occurrence not well understood statistically although intuitively self-evident and taken for granted. In this study, we used linear prediction theory (essentially correlation-regression) for height projection to better understand this phenomenon as related to three mean-covariance models, including an unstructured (essentially sample means, variances, and correlations) model and two structured models with means approximated by using the Chapman-Richards function and variances-covariances directly or indirectly modeled (i.e., mixed-effects modeling). An empirical evaluation of dominant height projection by the three models was performed using a second-rotation loblolly pine (Pinus taeda L.) plantation data set. The results showed that weakening correlations inherent in distant remeasurements largely determine projection accuracy to decline and that the squared coefficient of correlation (R2) can serve as an upper-limit measure of regression-type linear prediction of heights given one single prior measurement. The unstructured model directly estimated means and covariances without involving any function approximation; therefore, it provided best fits in terms of likelihood-based measures and better (smaller root mean squared error) prediction when applied to new individual plots, becoming a nearly top-limit standard model for comparison with other linear predictors of heights.
