Certificação e selos de qualidade asseguram requisitos na produção.
Em 2011, o Committee on Fisheries (Cofi) da Food and Agriculture Organization (FAO) comitê de pesca da FAO, órgão da Organização das Nações Unidas (ONU) aprovou o documento que contém as Diretrizes Técnicas para Certificação da Aquicultura, visando ao desenvolvimento, à organização e à implementação de regimes confiáveis de certificação de aquicultura. Os países signatários deverão internalizá-lo e usá-lo como base para adaptar ou criar as normas relacionadas ao tema. O documento abrange questões de saúde e bem-estar animal, segurança alimentar, integridade ambiental e aspectos socioeconômicos
Space Station Freedom coupling tasks: An evaluation of their space operational compatibility
The development of the Space Station Freedom tasks that are compatible with both telerobotic as well as extravehicular activity is a necessary redundancy in order to insure successful day to day operation. One task to be routinely performed aboard Freedom will be the changeout of various quick disconnect fluid connectors. In an attempt to resolve these potentially contradictory issues of compatibility, mock-ups of couplings suitable to both extravehicular as well as telerobotic activity were designed and built. An evaluation performed at the Remote Operator Interaction Laboratory at NASA's Johnson Space Center is discussed, which assessed the prototype couplings as well as three standard coupling designs. Data collected during manual and telerobotic manipulation of the couplings indicated that the custom coupling was in fact shown to be faster to operate and generally preferred over the standard coupling designs
Charge Influence On Mini Black Hole's Cross Section
In this work we study the electric charge effect on the cross section
production of charged mini black holes (MBH) in accelerators. We analyze the
charged MBH solution using the {\it fat brane} approximation in the context of
the ADD model. The maximum charge-mass ratio condition for the existence of a
horizon radius is discussed. We show that the electric charge causes a decrease
in this radius and, consequently, in the cross section. This reduction is
negligible for protons and light ions but can be important for heavy ions.Comment: 4 pages, 0 figure. To be published in Int. J. Mod. Phys. D
