| Group B Streptococcus (GBS) is the most common cause of life-threatening infection in neonates. Guidelines from CDC recommend universal screening of pregnant women for rectovaginal GBS colonization. The objective of this study was to compare the performance of a combined enrichment/PCR based method targeting the atr gene in relation to culture using enrichment with selective broth medium (standard method) to identify the presence of GBS in pregnant women. Rectovaginal GBS samples from women at ≥36 weeks of pregnancy were obtained with a swab and analyzed by the two methods. A total of 89 samples were evaluated. The prevalence of positive results for GBS detection was considerable higher when assessed by the combined enrichment/PCR method than with the... |

| The development of multi-analyte methods for lipophilic shellfish toxins based on liquid chromatography-mass spectrometry permits rapid screening and analysis of samples for a wide variety of toxins in a single run. Validated methods and appropriate certified reference materials (CRMs) are required to ensure accuracy of results. CRMs are essential for accurate instrument calibration, for assessing the complete analytical method from sample extraction to data analysis and for verifying trueness. However, CRMs have hitherto only been available for single toxin groups. Production of a CRM containing six major toxin groups was achieved through an international collaboration. Preparation of this material, CRM-FDMT1, drew on information from earlier studies as... |

| To monitor coastal environments, Unmanned Aerial Vehicle (UAV) is a low-cost and easy to use solution to enable data acquisition with high temporal frequency and spatial resolution. Compared to Light Detection And Ranging (LiDAR) or Terrestrial Laser Scanning (TLS), this solution produces Digital Surface Model (DSM) with a similar accuracy. To evaluate the DSM accuracy on a coastal environment, a campaign was carried out with a flying wing (eBee) combined with a digital camera. Using the Photoscan software and the photogrammetry process (Structure From Motion algorithm), a DSM and an orthomosaic were produced. Compared to GNSS surveys, the DSM accuracy is estimated. Two parameters are tested: the influence of the methodology (number and distribution of... |

| Registros de produção de leite de 19.151 lactações de 8.984 vacas, filhas de 795 touros Gir, foram usados para avaliar geneticamente as vacas. Equação de modelo misto foi usada para predizer o valor genético dos touros que foram incorporados no índice de seleção das vacas. Além do índice de seleção, os modelos animais foram também usados para predizer o valor genético das vacas, usando somente a primeira lactação ou até cinco lactações por vaca. As confiabilidades das predições obtidas dos valores genéticos das vacas usando-se os modelos animais foram maiores, quando foram usadas na avaliação até cinco lactações (0,76) ou somente a primeira lactação (0,73), em relação às confiabilidades das predições obtidas pelos índices de seleção (0,55 a 0,59).... |

| Dentre as diversas tecnologias utilizadas para a geração de modelos tridimensionais da superfície terrestre, o uso de Aeronaves Remotamente Pilotadas, popularmente conhecida como Drone, surgem como alternativa rápida e precisa em comparação às técnicas de topografia tradicionais. Diante dessa nova tecnologia, este estudo avaliou dois Modelos Digitais de Superfície, gerados por dois diferentes modelos de equipamentos e sensores, em uma bancada de extração de calcário dolomítico, no município de Almirante Tamandaré, no Estado do Paraná. A avaliação foi realizada com base no método de testes de hipóteses, a partir da análise de tendência e precisão, e os resultados foram classificados de acordo com o Padrão de Exatidão Cartográfica dos Produtos Cartográficos... |

| Carcass data from more than 38,000 cattle was used to compare the called and measured yield grade in two different periods: before and after the slaughter plant incorporated another grader in the line to improve grading accuracy. The study shows that the graders accuracy significantly increased. The higher accuracy affected all yield grades, but most notably resulted in more called yield grade 4 and 5 carcasses. This analysis will develop insight of what will be the effect of instrument grading that will be more accurate than previously called grades.The results are expressed as the conditional distribution of the called yield grade for a given value of the measured yield grade. The pricing grid currently used by the industry was used to analyze the effect... |

| O cajueiro (Anacardium occidentale) é uma das principais frutíferas cultivadas e adaptadas às regiões tropicais de clima semiárido do mundo. No entanto, apesar de sua rusticidade, é acometido por um grande número de doenças, principalmente causadas por fungos. Dentre essas, o oídio, causada por Pseudoidium anacardii, é atualmente a principal enfermidade dessa cultura, afetando folhas, inflorescências e frutos da planta. Devido à importância dessa doença, à carência na literatura de trabalhos detalhados que associem o efeito de P. anacardii à produtividade de A. occidentale e, ainda, à ausência de métodos padronizados para a quantificação da severidade da doença nesse patossistema, objetivou-se com o presente estudo determinar a relação entre a intensidade... |

| The objective of this work was to evaluate the application of the spectral-temporal response surface (STRS) classification method on Moderate Resolution Imaging Spectroradiometer (MODIS, 250 m) sensor images in order to estimate soybean areas in Mato Grosso state, Brazil. The classification was carried out using the maximum likelihood algorithm (MLA) adapted to the STRS method. Thirty segments of 30x30 km were chosen along the main agricultural regions of Mato Grosso state, using data from the summer season of 2005/2006 (from October to March), and were mapped based on fieldwork data, TM/Landsat-5 and CCD/CBERS-2 images. Five thematic classes were considered: Soybean, Forest, Cerrado, Pasture and Bare Soil. The classification by the STRS method was done... |

| The aggregate backscattering cross-section, sag, is the sum of backscattering cross-sections of all fish in a shoal. It is a basic acoustical parameter used for shoal description and biomass estimation. Simulations were undertaken for evaluating the impact of horizontal dimension, density, depth and beam width on measurements of sag for shoals with constant abundance. The important factor determining measurement bias is the ratio of shoal size expressed as along cross-section length relative to along ship beam width at mean shoal depth. The results show that 10 log10(sag) is underestimated by about 8 dB for a 5 m long shoal located at 200 m depth if detected by a 7? beam. A formula for correcting sag estimates for shoal sizes bigger than 1.3 times the beam... |
