Os textos no ensino de filosofia

When someone teaches Philosophy, he or she must be conscious that in the texts there is a compound of three kinds of experience: reading, thinking and writing. These three types of experience blend form and content of the text when one thinks, writes and reads. Then these experiences have an face as shape and another face including thinking, writing and reading in a continuous tension because it is related to a practice that is in this same context, that of philosophy.

Fingerbyte: utilizando conceitos teóricos de comunicação e pesquisa de opinião para adequação de um produto

This project aims to use concepts of innovation and obsolescence in products, to analyze and test the technological product FingerByte, a blend glove and joystick that needs to be appropriate for specific audiences. For this adjustment, this project uses a qualitative opinion survey, known as focus group in order to obtain data during product testing with certain audiences. Another purpose of the paper is to serve as a guide to readers in similar situations where you wish to use focus groups to develop products that have not been put on the market. The experiment uses the knowledge of public relations, both in research and in data analysis. The main results of the research are described in this monograph, in order to demonstrate what are the possible types of data being collected, helping the reader to approach the experience of qualitative research

Effect of temperature on salt-salt aqueous biphasic systems: manifestations of upper critical solution temperature

Water-miscible ionic liquids (ILs) may be salted out using kosmotropic salts such as potassium phosphate (K3PO4) to form salt-salt aqueous biphasic systems (ABS). The effect of temperature on these systems has been studied using phase diagrams and it is observed that the degree of binodal shift decreases (requiring lower IL and kosmotropic salt concentrations) with the increase of temperature following the trend [C(4)mim]Cl > [C(4)py]Cl > [C(4)mmim] Cl > [N-4444]Cl. This trend can be correlated with the decreasing hydrogen bonding abilities of each salt. The phase behavior was also interpreted on the basis of critical solution temperature behavior of pure aqueous ionic liquid solutions. Additionally, the distribution of alcohols in these systems was studied as a function of temperature and it was found that the distribution ratios did not change with changes in temperature. The Gibbs energy of transfer of a methylene group in these systems and correlation to tie-line length was also determined. It was concluded that while the miscibility of alcohols increases in the ILs with increasing temperature, phase divergence in the aqueous biphasic system decreases, and thus these competing forces tend to cancel each other out for small polar molecules. A comparison is provided for the response to temperature in the currently studied salt-salt systems and analogous ABS formed by the addition of hydrophilic polymers to kosmotropic salts (polymer-salt) or other polymers (polymer-polymer).

Desenvolvimento e caracterização de dispositivos eletroluminescentes contendo uma blenda polimérica condutora e Zn2SiO4:Mn

Despite the great development of organic and polymeric electroluminescent materials, the large scale commercial application of devices made with these materials seems conditioned to specific cases, mainly due to the high cost and the low durability, in compared to conventional technologies. In this study was produced electroluminescent devices by a process simple, drop casting. Were produced electroluminescent films containing Zn2SiO4:Mn immersed in a conductive polymer blend with different thicknesses. The morphological characteristics of these films were studied by scanning electronic microscopy. These films were used in the manufacture of electroluminescent devices, in which the light emission properties of the developed material were evaluated. The blend was composed of the conductive polymer Poly(o-methoxyaniline), doped with p-toluene sulfonic acid, and an insulating polymer, Poly(vinylidene fluoride) and its copolymer Poly(vinylidene fluoride-cotrifluoroethylene). To this blend was added Zn2SiO4:Mn, thereby forming the composite. A first set of devices was obtained using composites with different weight fraction of polymeric and inorganic phases, which were deposited by drop casting over ITO substrates. Upper electrodes of aluminum were deposited by thermal evaporation. The resulting device architecture was a sandwich type structure ITO/ composite/ Al. A second set of devices was obtained as self-sustaining films using the best composite composition obtained for the device of the first set. ITO electrodes were deposited by RF-Sputtering, in both faces of these films. The AC electrical characterization of the devices was made with impedance spectroscopy measurements, and the DC electrical characterization was performed using a source/ meter unit Keithley 2410. The devices light emission was measured using a photodiode coupled to a digital electrometer, Keithley 6517A. The devices electrooptical characterization showed that the...

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.
