| Abstract:This study aims to use the method of laser reflection from the surface of strawberry fruits to classify different strawberry defects to facilitate the process of sorting the fruits during the handling process. The study was conducted on exposing the strawberry fruits (festival variety) by laser radiation with wavelengths of 543.5 and 632.8 nm, after dividing the fruits into six groups according to strawberry defects, to measure the amounts of reflected radiation and generated electricity. The results obtained were the following: a) For the physical and chemical properties of strawberry fruits: It was found that there is no dispersion in (height, width, length, volume, weight, total soluble solids (Brix) and the pH value of the fruits). Their... |

| Modern marine hydrothermal vents occur in a wide variety of tectonic settings and are characterized by seafloor emission of fluids rich in dissolved chemicals and rapid mineral precipitation. Some hydrothermal systems vent only low‐temperature Fe‐rich fluids, which precipitate deposits dominated by iron oxyhydroxides, in places together with Mn‐oxyhydroxides and amorphous silica. While a proportion of this mineralization is abiogenic, most is the result of the metabolic activities of benthic, Fe‐oxidizing bacteria (FeOB), principally belonging to the Zetaproteobacteria. These micro‐organisms secrete micrometer‐scale stalks, sheaths, and tubes with a variety of morphologies, composed largely of ferrihydrite that act as sacrificial structures, preventing... |

| Typhoons are assumed to stimulate ocean primary production through the upward mixing of nutrients into the surface ocean, based largely on observations of increased surface chlorophyll concentrations following the passage of typhoons. This surface chlorophyll enhancement, seen on occasion by satellites, more often is undetected due to intense cloud coverage. Daily data from a BGC-Argo profiling float revealed the upper-ocean response to Typhoon Trami in the Northwest Pacific Ocean. Temperature and chlorophyll changed rapidly, with a significant drop in sea surface temperature and surge in surface chlorophyll associated with strong vertical mixing, which was only partially captured by satellite observations. However, no net increase in vertically integrated... |

| In mollusk aquaculture, a large number of Vibrio species are considered major pathogens. Conventional methods based on DNA amplification and sequencing used to accurately identify Vibrio species are unsuitable for monitoring programs because they are time-consuming and expensive. The aim of this study was, therefore, to develop the MALDI-TOF MS method in order to establish a rapid identification technique for a large panel of Vibrio species. We created the EnviBase containing 120 main spectra projections (MSP) of the Vibrio species that are potentially responsible for mollusk diseases, comprising 25 species: V. aestuarianus, V. cortegadensis, V. tapetis and species belonging to the Coralliilyticus, Harveyi, Mediterranei, and Orientalis clades. Each MSP was... |

| Resumo: O produto interno bruto (PIB) do agronegócio teve participação de 22,08% no PIB nacional, no último ano do período de 2005 a 2017. No setor, a maior participação foi dada pelo agregado de agrosserviços que teve, em média, 53,02% do total do PIB do agronegócio. Essa presença ativa mostra que, a jusante, há vínculos de grande relevância a serem considerados. Os valores encontrados para o PIB da bovinocultura de corte apresentam uma participação deste no PIB do agronegócio de 15,98%, também primordialmente representados pelos agrosserviços, que tiveram aumento acumulado de 25,39% no período. O método da matriz insumo-produto permitiu que fossem observadas todas as taxas de crescimento e queda dos agregados selecionados da bovinocultura de corte... |

| Despite the large number of species distribution modelling (SDM) applications driven by tracking data, individual information is most of the time neglected and traditional SDM approaches commonly focus on predicting the potential distribution at the species or population‐level. By running classical SDMs (population approach) with mixed models including a random factor to account for the variability attributable to individual (individual approach), we propose an innovative five‐steps framework to predict the potential and individual‐level distributions of mobile species using GPS data collected from green turtles. Pseudo‐absences were randomly generated following an environmentally‐stratified procedure. A negative exponential dispersal kernel was... |

| A morte precoce do pessegueiro é uma síndrome que provoca severos danos às plantas, normalmente com idade entre um e oito anos, podendo levar à morte da copa. No Brasil, tem importância principalmente no estado do Rio Grande do Sul, que é o maior produtor brasileiro de pêssegos. Identificada pela primeira vez no final da década de 1970, na região de Pelotas, a síndrome vem provocando prejuízos, com intensidades variáveis de um ano para outro. Diversas causas já foram relatadas pela literatura nacional e internacional, envolvendo fatores bióticos e abióticos. No Rio Grande do Sul, devido ao uso predominante de misturas de caroços da indústria conserveira para a produção de porta-enxertos, não é possível conhecer a identidade varietal do sistema radicular... |

| The increasing global consumption of seafood has led to increased trade among nations, accompanied by mislabeling and fraudulent practices that have rendered authentication crucial. The multi-isotope ratio analysis is considered as applicable tool for evaluating geographical authentications but requires information and experience to select target elements such as isotopes, through a distinction method based on differences in habitat and physiology due to origin. The present study examined recombination conditions of multi-elements that facilitated geographically distinct classifications of the clams to sort out appropriate elements. Briefly, linear discriminant analysis (LDA) analysis was performed according to several combinations of five stable isotopes... |
