| The Conference of Brussels, called in 1853, was the first International Maritime Conference ever held. It sponsored the idea that governments should foster systematic weather observations on ships, and should prepare and publish charts of the prevailing winds, ocean currents, average sea and air temperatures, and tracks of dangerous storms based on the additional data. With the introduction of radio and fast ships, weather information became of vital importance to safe and efficient ship operation. Many countries began regularly scheduled weather forecasts to ships in nearby waters. Today, weather forecasts as well as charts are prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,... |

| A variety of ecotoxicological methods have been worked out and are described in the scientific literature to experimentally predict the impact of chemical substances on aquatic terrestrial biota. Only during recent years have serious efforts been made at both the national and international level to select a few bioassays which should be standardized for general applicability. The choice for a standard bioassay, of the test species as well as of the criterion to assess the dose-effect relationship is a matter of the compromises which one is willing to make between the factors ecological representativeness and sensitivity on one hand, and mangeability in the laboratory and cost of the test on the other hand. This assertion is demonstrated for the aquatic... |

| Since some decades, agrifood products exchanges can be carried on using Information and Communication Technology (ICT) tools. Anyway, their adoption in the agrifood sector appears to be hindered, both because of consolidated dynamics in developing B2B transactions, and of the peculiarities of the agrifood products themselves. The lack of direct relationships between partners heighten problems connected with food safety assessments, and with the definition of standardized production practices able to match business partners’ needs. Standardization is the key point in the relationship between e-commerce and agrifood sector. As for some products it is possible to define standardized requirements, it is hard to find a collocation for the wide range of agrifood... |

| ABSTRACT Grain quality determination involves important stages such as collection of the representative sample, homogenization, and dilution. The interrelation among sampling, homogenization, and working sample size is essential to the reliability of the information generated. Therefore, this work aimed to analyse the performance of mechanical homogenizers used in the commercialization of grains in Brazil, as a function of the size of the working sample masses during grain classification. The samples were homogenized and diluted in Boerner, 16:1 multichannel splitter, and 4:1 multichannel splitter until reaching masses of 0.025, 0.050, 0.075, 0.100 and 0.125 kg to determine the level of damaged grains. A 3 x 4 x 5 factorial design was used, meaning three... |

| Abstract Small ruminant lentiviruses (SRLV) have high genetic variability which results in different viral strains around the world. This create a challenge to design sensible primers for molecular diagnosis in different regions. This work proposes a protocol of duplex nested-PCR for the precise diagnosis of SRLV. The technique was designed and tested with the control strains CAEV Co and MVV 1514. Then, field strains were submitted to the same protocol of duplex nested-PCR. Blood samples of sheep and goats were tested with AGID and nested PCR with specific primers for pol, gag and LTR. The AGID results showed low detection capacity of positive animals, while the nested PCR demonstrated a greater capacity of virus detection. Results demonstrated that... |
