Qualidade tecnológica da cana-de-açúcar sob adubação com torta de filtro enriquecida com fosfato solúvel

The study had the objective to evaluate the effect of the fertilization with filter cake enriched with soluble phosphate on the sugar yield. The experiment carried at Presidente Prudente-SP, used a randomized complete block design, in the factorial scheme 5 x 4, where the first factor consisted of doses of filter cake (0; 0.5; 1.0; 2.0 and 4.0 t ha(-1)) and the second, doses of phosphorus fertilizer (0, 50, 100, 200 kg ha(-1) of P2O5), with 4 replicates, totaling 80 plots. The results indicated that phosphorus applied in planting furrows improves the quality of sugarcane raw matter by increasing the levels of soluble solids, total reducing sugars and sucrose in the stalks. The phosphorus also increases the productivity of sugar. The filter cake applied in planting furrow has the potential to partially replace the chemical fertilization with phosphate aiming to improve the quality and the productivity of sugar. The best combination was filter cake at dose between 2.6 and 2.7 t ha(-1) combined with dose between 160 and 190 kg P2O5 ha(-1) for obtaining best response of soluble solids and productivity of sugar.

Análise bibliométrica da produção tecnológica em biodiesel: contribuições para uma política em CT&I

This paper analyzes the international technological production on biodiesel using bibliometric indicators of patents. The data were gathered from Derwent Innovations Index, from 2000 to 2007. The evolution of patent registration by organizations and individuals was analyzed as well as the classification of inventions. The results are useful to visualize the dynamics of technological production on biodiesel and lay grounds for reflections on use of bibliometric indicators and for ST&I policy in the biodiesel field.

Inovação tecnológica e o mercado de trabalho do engenheiro cartógrafo

The article focuses on the presence of the technologic innovation and the surveyed current conditions of the cartographic engineer's work market. The methodology is based on forms with objective questions answered by the professionals. The current survey is the fourth one starting in 1995 and the first one with on line forms filled out by the Brazilian Association of Cartographic Engineers - São Paulo Section's web page. The sample was made up with 141 engineers and it revealed numbers that confirm the growing visibility and social recognition of the Brazilian cartographic engineer, although still far from the condition consistent with the territorial extension and the importance of Cartography for the country. The survey shows that the monthly average revenues are of approximately fifteen minimum wages; that the sample has only 13% of employers, although it is the highest percentage among all surveys; that 63 professionals cited 127 times that their organizations are related to technologic innovation at a proportion of two citations per organization; that 69% of the sample are optimists concerned to the future. Other important pieces of in formation to students and professionals will also be discussed in the article.
