The persistence of the herbicide picloran (4-amino - 3,5,6 - trichloropicolinic acid) was studied in "Latossolo vermelho" soil (36% clay, 2% organic matter) in Jaguariuna county, Sao Paulo, Brazil. The herbicide was sprayed on plowed soil in March, 1989, at rates of 0.0; 0.56 and 1.12 g/ha. Picloran persistence was evaluated using bioassay with bean (Phaseolus vulagris L.). The data showed that the herbicide was very persistent up to 180 days, just at the raining season, October to December. At the same interval, from 180 to 240 days, typical visual symptoms disappeared, although there were still effects on height of plants, length of leaves and dry weight. No effect of the herbicide was detected after 300 days. |

Abstract. An innate characteristic of the development of ontologies is that they are often created by independent groups of expertise, which generates the necessity of merging and aligning ontologies covering overlapping domains. However, a central issue in the merging process is the evaluation of the differences between two ontologies, viz. the establishment of a similarity measure between their concepts. Many algorithms and tools have been proposed for merging of ontologies, but the majority of them disregard the structural properties of the source ontologies, focusing mostly on syntactic analysis. This article focuses on the alignment of ontologies through Formal Concept Analysis, a data analysis technique founded on lattice theory, and on the use of similarity measures to identify cross-ontology related concepts |
