Saúde, comunicação e nanotecnologia: o papel do debate público para a expansão da cidadania

Amongst thematic networks, strategic laboratories and master and doctorate scholarships awarded by the National Program of Nanotechnology, an actor of great relevance can be distinguished due to its relative absence: the lay people, once more relegated to a secondary agent in Brazilian democracy, although citizens’ views have been increasingly recognized all over the world as an indispensable factor to the science and technology public policies which are intended to be democratic. Whereas Europe and United States have incorporated public values and feelings in the policy planning, Brazil is still waiting for opportunities of public participation in the definition of research guidelines. This paper examines contemporaneous demands of science communication to the strengthening of citizenship, aiming to offer contributions to a debate directed to question the present arrangement — of antidemocratic indifference towards the public — adopted in the formulation of public policies in Brazil.

O Ensino de Acústica nos livros didáticos de Física recomendados pelo PNLEM: análise das ligações entre a física e o mundo do som eda música

This paper presents an analysis of the content in acoustics present in physics textbooks recommended by PNLEM, which used the same criteria of evaluation from used by experts in the analysis of such books. In this way, we observed that such texts have evolved little in comparison with the textual presentations reviewed in 1998 and published in the journal Science and Education [1], which were analyzed ten physics textbooks for high school, among which the most commom, at the time, in Brazilian schools. Although we identified the inclusion of some aspects of the culture of sound and music, there are still several conceptual and historical distortions, besides the little importance has been given to links CTSA, among them, studies of soundscapes that, even, are mentioned.

Avaliação energética econômica do agroecossistema algodão: uma abordagem entre sistemas familiares de produção do Paraguai e do Brasil

The objective of this work was to evaluate the energy and economic efficiency indexes per unit of cotton agro-ecosystem area in family production systems of Paraguay and Brazil; and, to establish a relationship between the energy and economic. Typologies presented by the Program to Support Small Cotton Holdings (Paraguay), and by the National Program for Strengthening Family Agriculture (Brazil). Family systems of the two countries were identified; these are located from Paraguay (San Juan–CA) and from Brazil (Leme–SP). To construct the energy expenditure structure of the cotton agro-ecosystem, as well as to assess the economic efficiency, the mean values obtained were considered, when they presented similarities in production systems and they were within the typology proposed in this study. From the technical itinerary observed the Paraguayan agro-ecosystem depended (fossil fuel 56.76%) and industrial source (35.99%). Thus, the energy balance of the agricultural stage was established, which attained a value of 17,740.69 MJ ha-1; an energy efficiency of 5.28, and a cultural efficiency of 3.04. The Brazilian agro-ecosystem depended on energy from industrial source (insecticides 39.82%) and from fossil fuel (33.59%); it reached an energy balance of 19,547.88 MJ ha-1; an energy efficiency of 2.12, and a cultural efficiency index of 0.71. In the economic and energy indicator ratio, with regard to the months referring to the harvest time, that is to say, March, April, and May, the maximum economic efficiency indicator of paraguay was attained in the month of May (1,00), and from Brazil in the month of May (1,71). Both production systems analyzed were presented efficient, however, dependent of external circumstances and non-renewable energy sources.

Comparação do custo de produção do crambe (Cambe abyssinica Hochst) com outras culturas oleaginosas em sistema de plantio direto

Biodiesel is a reality in Brazil, due to the National Program of Biodiesel Production and Use (PNPB), which became mandatory in 2008 in adding 2% biodiesel in all diesel sold in a blend known as B2. The agribusiness sector responded to the federal program, facing many difficulties in biodiesel production, which highlights the supply of raw material. Problems related to biodiesel production were mainly the shortage of vegetable oil, because of demand from domestic and foreign markets, and rising prices of raw materials available for production, making this biofuel production economically feasible, even in Brazil, where agricultural production costs are among the most competitive in the world. The crambe is a specie that has aroused the interest of Brazilian producers due to oil content, hardiness, and mechanized cultivation, mainly for being a winter crop, it becomes one more option for farmers in this period. In addition, you can compose systems of crop rotation as well as being used as ground cover in winter. The aim of this study was to evaluate the potential for productive and cost of production of crambe, conducted in no-tillage system, to compare these parameters with other oil crops such as sunflower, canola and soybean. The trial was conducted in the agricultural year 2008 at the Experimental Farm Lageado belonging to the Faculty of Agronomic Sciences - UNESP, located in Botucatu - SP. The estimated yield was 1.507,05 kg ha-1, resulting in a production of 561,94 liters of oil per hectare. The cost of installation and conduct of crambe per hectare was R$ 875,87, resulting in a cost of R$ 1,56 per liter of oil, the lowest cost among the oilseed crops analyzed.

Cana-de-açúcar e álcool combustível: histórico, sustentabilidade e segurança energética

The cane sugar is important since the early days in the history of the country, following the discovery of Brazil since the colonial period, therefore, the culture has an important role in the Brazilian economy, being one of the main products. In the 1970s with the advent of the economic crisis, geopolitical and the possibility of depletion of oil, countries dependent on imported fuel, sought new energy alternatives. In Brazil, it was decreed in 1975 the creation of the National Alcohol Program - PROALCOOL, who had several years of rising, the increase of distilleries and marketing of cars powered with ethanol blend. Due to the decrease in the price of oil the importance of the program significantly reduced, returning to peak only in 1979, ie, the second phase of the program. Conceived as one of the vectors of the national response to the crisis in oil prices '70s, the program persisted at times rising in others not reaching for more than three decades. Brazil is the second largest ethanol producer, second only to the U.S., where the raw material comes from corn, which becomes a bottleneck biodiesel production because it competes with food production. New technologies developed to increase ethanol production combined with sustainability and economic viability are being held, the principal is the second generation ethanol, known as cellulosic ethanol, ethanol plus third and fourth generation.
