| Dado que el picudo del chile es el principal problema fitosanitario en el cultivo de Capsicum spp., y las medidas de control no han logrado mitigar de forma eficiente las poblaciones de este insecto, se estudiaron los siguientes objetivos con el fin de conocer las interacciones planta insecto. Primero se valido un método de recolecta de volátiles, el cual demostró ser eficiente bajo las diferentes variables analíticas estudiadas, con % de recobro de 90-100 y DER menores a 10%. En segundo lugar se evaluó el potencial atrayente de estructuras de la planta como flores, yemas, frutos en desarrollo y frutos comerciales, encontrando que machos prefieren en primer lugar flores y después yemas, y las hembras en su primera opción eligieron yemas y después flores.... |

| El estudio tuvo como objetivo estandarizar y validar la técnica de Reacción en Cadena de la Polimerasa (PCR) para la detección de Salmonella typhimurium (St) en carne de cerdo, res y pollo, optimizando el tiempo y la sensibilidad con relación al método microbiológico; además se realizó el diagnóstico en estos tipos de carnes para evaluar su calidad microbiológica en la Ciudad de Texcoco. Un total de 60 muestras de carne (20 de cerdo, 20 de res y 20 de pollo) de 250 g fueron recolectadas en puntos de venta de la Ciudad de Texcoco. Las muestras recolectadas procedían de carnicerías, tianguis y supermercados. Se evaluó la sensibilidad y especificidad de la PCR para detectar St; asimismo, se validó esta técnica en relación al método microbiológico con base al... |

| Hydrological models are important tools that have been used in water resource planning and management. Thus, the aim of this work was to calibrate and validate in a daily time scale, the SWAT model (Soil and Water Assessment Tool) to the watershed of the Galo creek , located in Espírito Santo State. To conduct the study we used georeferenced maps of relief, soil type and use, in addition to historical daily time series of basin climate and flow. In modeling were used time series corresponding to the periods Jan 1, 1995 to Dec 31, 2000 and Jan 1, 2001 to Dec 20, 2003 for calibration and validation, respectively. Model performance evaluation was done using the Nash-Sutcliffe coefficient (E NS) and the percentage of bias (P BIAS). SWAT evaluation was also... |

| Abstract Lysosomal storage disorders (LSDs) constitute a heterogeneous group of approximately 50 genetic disorders. LSDs diagnosis is challenging due to variability in phenotype penetrance, similar clinical manifestations, and a high allelic heterogeneity. A powerful tool for the diagnosis of the disease could reduce the “diagnostic odyssey” for affected families, leading to an appropriate genetic counseling and a better outcome for current therapies, since enzyme replacement therapies have been approved in Brazil for Gaucher, Fabry, and Pompe diseases, and are under development for Niemann-Pick Type B. However, application of next-generation sequencing (NGS) technology in the clinical diagnostic setting requires a previous validation phase. Here, we... |

| Développé par le laboratoire DEL/AO à Brest et appliqué à la rade de Toulon, le modèle MARS-3D a été installé au laboratoire de Toulon. L'objectif est de mettre en route son application à Toulon et de contribuer à l'analyse en cours des résultats du modèle, en les· comparant aux mesures historiques. Dans ce rapport sont présentés les travaux faits pour réaliser ce double objectif: l'apprentissage du modèle dans sa conception et son utilisation, l'analyse des résultats et la comparaison avec des mesures ainsi qu'une simulation de traceurs. La comparaison du modèle avec les données a été réalisée sur la base des enregistrements faits en 1986-1987 en un point de mesure au centre de la grande rade. Or, l'emboîtement des modèles crée une contrainte sur le... |

| Gaofen-3 (GF-3) is the first Chinese civil C-band synthetic aperture radar (SAR) launched on 10 August 2016 by the China Academy of Space Technology (CAST), which operates in 12 imaging modes with a fine spatial resolution up to 1 m. As one of the primary users, the State Oceanic Administration (SOA) operationally processes GF-3 SAR Level-1 products into ocean surface wind vector and plans to officially release the near real-time SAR wind products in the near future. In this paper, the methodology of wind retrieval at C-band SAR is introduced and the first results of GF-3 SAR-derived winds are presented. In particular, the case of the coastal katabatic wind off the west coast of the U.S. captured by GF-3 is discussed. The preliminary accuracy assessment of... |

| [1] Recently developed algorithms have shown the potential recovery of rainfall information from spaceborne dual-frequency altimeters. Given the long mission achieved with TOPEX and the prospect of several other dual-frequency altimeters, we need to validate the altimetrically derived values so as to foster their integration with rain information from different sensors. Comparison with some alternative climatologies shows the bimonthly means for TOPEX to be low. Rather than apply a bulk correction we investigate individual rain events to understand the cause of TOPEX's underestimation. In this paper we compare TOPEX with near-simultaneous ground-based rain radars based at a number of locations, examining both the detection of rain and the quantitative... |

| Les performances du modèle communautaire CROCO sont évaluées grâce à un jeu de données in-situ complet (courant, hauteur d’eau, température, salinité) et comparées à celles du modèle MARS-3D. Il apparaît que les modèles ont un comportement hydro-dynamique proche avec des divergences liées au coeur numérique de CROCO (schéma temporel, schéma d’advection). A ce stade, ces divergences n’apparaissent pas discriminantes pour CROCO. |

| Close similarities have been found between the otoliths of sea-caught and laboratory-reared larvae of the common sole Solea solea (L.), given appropriate temperatures and nourishment of the latter. But from hatching to mouth formation. and during metamorphosis, sole otoliths have proven difficult to read because the increments may be less regular and low contrast. In this study, the growth increments in otoliths of larvae reared at 12 degrees C were counted by light microscopy to test the hypothesis of daily deposition, with some results verified using scanning electron microscopy (SEM), and by image analysis in order to compare the reliability of the 2 methods in age estimation. Age was first estimated (in days posthatch) from light micrographs of whole... |

| The Advanced Along-Track Scanning Radiometer (AATSR) onboard Envisat is designed to provide very accurate measurements of sea surface temperature (SST). Using colocated in situ drifting buoys, a dynamical matchup database (MDB) is used to assess the AATSR-derived SST products more precisely. SST biases are then computed. Currently, Medspiration AATSR SST biases are discrete values and can introduce artificial discontinuities in AATSR level-2 SST fields. The new AATSR SST biases presented in this letter are continuous. They are computed, for nighttime and best proximity confidence data, by linear regression with different MDB covariables (wind speed, latitude, aerosol optical depth, etc.). As found, the difference between dual-view and nadir-only SST... |

| An inter-laboratory study of the accuracy of microbial source tracking (MST) methods was conducted using challenge fecal and sewage samples that were spiked into artificial freshwater and provided as unknowns (blind test samples) to the laboratories. The results of the Source Identification Protocol Project (SIPP) are presented in a series of papers that cover 41 MST methods. This contribution details the results of the virus and bacteriophage methods targeting human fecal or sewage contamination. Human viruses used as source identifiers included adenoviruses (HAdV), enteroviruses (EV), norovirus Groups I and II (NoVI and NoVII), and polyomaviruses (HPyVs). Bacteriophages were also employed, including somatic coliphages and F-specific RNA bacteriophages... |

| Assessing the validity of a model is essential for its credibility especially when the model is used as decision making tool. Complex dynamic fishery models are recommended to investigate the functioning of fisheries and to assess the impact of management strategies, particularly spatial fishing regulations. However, their use is limited due to the difficulty and computational cost of parameterizing and gaining confidence, particularly for parameter rich models. These difficulties are compounded by uncertainty regarding parameter values, many of which are often taken from literature or estimated indirectly. Here we propose a methodology to improve confidence and understanding in the model, easily transferable to any complex model. The approach combines... |
