Quando a superfície de resposta tem um ponto de sela ao invés de um ponto de máximo, é de grande importância, do ponto de vista prático, obter soluções alternativas para os níveis ótimos, i.e., a combinação de doses de nutrientes que dá a produção máxima. Três soluções alternativas foram estudadas por simulação: o ponto de máximo absoluto (ponto de máximo fronteira) na região experimental, o ponto de máximo experimental e o ponto de sela. Com exceção do ponto de sela, as soluções apresentaram boas propriedades como substitutas dos níveis ótimos. Utilizando o critério da frequência de máximos, também foi feita uma comparação entre nove delineamentos de tratamentos com três fatores e 3, 5, 7 e 9 níveis. O melhor delineamento de tratamentos foi o fatorial 33 com níveis igualmente espaçados.

Point positioning from GPS data can provide precision varying from 100 meters to a few millimeters at the level of 95% probability. To reach the best level of accuracy, users need proper equipment and software, as well as access capability to GPS products available at the International GPS Geodynamics Service. In this paper, the theory related to point positioning using GPS is presented as well as the results of an experiment conducted using data from the Brazilian Active Control System. The results show repeatability better than 5mm and 10mm for the N and E baseline components respectively, and 6mm + 4ppb (parts per billion) for the vertical. Comparison with SIRGAS campaign showed results at the same level of uncertainty as that of the stations used to tie the SIRGAS frame to ITRF94. Therefore, precise point positioning is a powerful tool to be used in applications requiring high level of precision, such as Geodynamics.

One of the main drawbacks of the GPS accuracy for L1 users is the error due to ionosphere. This error depends on the total electron content presents in the ionosphere, as well as of the carrier frequency. Some models have been developed to correct GPS observables of the systematic error due to the ionosphere. The model more known and used is the Klobuchar model, which corrected 50-60% of the ionospheric error approximately. Alternatively, IGS (International GNSS Service) also has developed a model called Global Ionospheric Map (GIM). These maps, in format IONEX, are available in the site of the IGS, and one of the applications of them is to correct the GPS observables of the error due to ionosphere. This work aims at evaluating the quality of GPS point positioning using the IGS ionospheric model in the Brazilian region. Tests carried out had shown an average improvement in the horizontal and vertical determination of 72% and 26%, respectively, when GIM is used in the point positioning.

A reflection is offered on the complementary relations among documentary languages, terminology, and ontologies, in regard to the study of conceptual relations used to organize knowledge. Building on selected texts from the international literature, the relations between documentary languages and different emerging technology solutions are analyzed, taking SKOS as a model; and also the relations among thesauri, ontologies and terminology, with the support of the theoretical concept of documentary representation. The adoption of the principles of terminology, as understood in Information Science, in building ontologies is supported; and the innovative opportunities offered by ontologies to the improvement and processing of conceptual relations in indexing languages is defended.

The Gerbera is an ornamental perennial herb, belonging to the Asteraceae family. Its cultivation, as well as the entire market for flowers and ornamental plants, is now in full expansion phase. The objective of this study was to evaluate the growth and quality Potted gerbera cultivar Red, according to sources and doses of potassium. The experiment was conducted in a greenhouse at UNESP/Botucatu. The experimental design was randomized blocks, using a 2x5 factorial arrangement, with two sources (potassium silicate and chloride) and five doses (0, 50, 100, 150 and 200 mg. L-1) 4 replications and 5 plants per plot. Weekly throughout the experimental period, assessments were made of the number of leaves (NL) and the diameter of the plant canopy (DP). at the end of the season and the reproductive cycle, at 42 and 60 days after acclimatization (DAA), respectively, were determined by leaf area (LA), mass (dry leaves (MSF), the dry mass of inflorescence (MSI) and total dry matter (TDM). at the point of marketing is that of open stamens, when the inflorescence had at least two rounds of open, releasing pollen, we determined the number of inflorescences (NI), the diameter of inflorescence (DI), the stem height (AH), the shank diameter (DH) and plant height (PH). Regardless of the doses, potassium silicate promoted greater diameter, leaf area, greater MSF, MST and increased stem height, characteristics that favor the sale of potted gerbera.

Pragmatism, as a formal method, has provided a fabulous arena for discussions about the way concepts may be constructed, irrespective of any anthropomorphic or linguistic position. We will see that the pragmatic maxim possesses an interesting thesis regarding the indetermination of the meaning. Such idea helps to understand the transit between the indefinite and the defined, indeterminate and determined, as well as some found intermediate borders in the processes of relative determination.
