Photoelectrochemical Hydrogen Generation and Concomitant Organic Dye Oxidation under TiO2 Nanotube

The present work describes the photoelectrochemical hydrogen generation during a photodegradation of an organic compound. For this, it was chosen the reactive black 5 dye as a model of organic pollutant and its oxidation under TiO2 nanotube in a two compartment cell. The photoelectrocatalysis is conducted in 0.1 mol L-1 Na2SO4 pH 6 medium under photoanode biased at +1.0 V (SCE) and activated by UV and visible light using 150W Xe-Arc lamp (Oriel) and 125 W Hg lamp (Osram). The concomitant hydrogen production was monitored at cathodic compartment using a Pt cathode. Using optimized condition of Na2SO4 0.1 mol L-1 pH 6 as supporting electrolyte, applied potential of +1.0V it was verified 100% of discoloration and 72% of TOC removal of 1.0 x 10(-5) mol L-1 Reactive Black 5 dye after 120 min of treatment (rate constant of 10.6 x10(-2) min(-1)). The concomitant hydrogen generation was 44% in this condition.

Memoria se deseja, o resto se ouça ou veja: considerações sobre um poema de Frederico Barbosa .(2010)

In Frederico Barbosa’s poem “Memoria se”, the memory experience is marked in the body, which means that the memory is not only recorded on the lyrical person unconsciousness, but it is also something that, as an insignia, presents itself and becomes dense as permanence in this lyrical person body. The poet is heir of what may be called “tradition of rigour,” consequently, a discussion of his poetics aspects must consider the inventiveness and the dialogue with other texts, not only those from the canon but also those from the popular repertory that Frederico Barbosa assimilates and recreates.

O enunciatário da revista VEJA: contribuição para discussões sobre indústria cultural e cultura de massa

This work intends to “test” two theories about mass cultural products – one that understands them as syncretic and plural and another that sees them as homogenizators and aimed to a mixed audience. We chose Veja magazine as the object of this study and tried to understand how its internal sessions bring in their readers, with the goal of verifying whether readers shared characteristics. In the affirmative case, Veja would be directed to a specific reader; otherwise, it would be a syncretic cultural product. This answer should give us basis to reflect upon the opposition between both ways of thinking about mass culture and help us take a stand on this discussion. Obviously, we do not intend to give a definitive answer to the opposition between these two tendencies. The limits of this work are given by the investigated object itself: we intend to verify empirically how Veja, as a cultural product, solves the contradiction that the co-existence of these two opposite theories point about mass society.

Lifespan and reproductive dynamics of the commercially important sea bob shrimp Xiphopenaeus kroyeri (Penaeoidea): synthesis of a 5-year study

Population parameters of the shrimp Xiphopenaeus kroyeri (Heller, 1862) (sex ratio, length-frequency distributions (carapace length, CL), growth, lifespan, size of sexual maturity, spawning and recruitment) were analyzed in a long-term study from January 1998 through June 2003. The data on these parameters were collected and analyzed to test the hypothesis that the main period of juvenile recruitment in the bay coincides with the period of fishery closures currently designated by the Brazilian Institute of Environment and Renewable Natural Resources. Monthly collections were conducted along the southeastern Brazilian coast, using a shrimp fishing boat with “double-rig” nets sampling at stations up to 40 m depth. Sex ratios were female-biased only in zones with high reproductive activity such as in stations deeper than 15 m (χ2 test, p<0.05). The mean size of males and females was 15.3 ± 3.1 mm CL and 16.2 ± 4.7 mm CL, respectively, with size at sexual maturity estimates (CL50) of 14.8 mm for males and 15.5 mm for females. Mean growth curves provided estimates of CL∞ = 29.31 mm, k = 0.009/day, t0=−0.25 and CL∞ = 35.33 mm, k = 0.006/day, t0=−0.23 for males and females, respectively, and average lifespans of 1.35 for males and 2.12 years for females. Recruitment and abundances of reproductive females were highly correlated with the environmental factors such as higher water temperature and finer-grained bottom sediment (canonical correlation, r=0.63, p<0.001). The reproductive peaks in February-April 1998, March-May 1999 and February-May 2002 were followed by recruitment peaks in May-July 1998, July-September 1999 and April-June 2002, respectively. Thus, the proposed period of fisheries closure (March to May) does not coincide with the main recruitment periods observed for X. kroyeri.

As mamas de Angelina Jolie e as relações de corpo, cultura e comunicação no discurso da revista Veja

This article analyzes the representation made by Veja magazine about american actress Angelina Jolie about the news about her preventive double mastectomy wich she was submitted. Based on the reflections of Michel Foucault, Gilles Deleuze and Felix Guattari on discourse analysis this article does not cramp about the contributions of linguistics. These reflections contribute to the understanding of this fact within the media landscape to control and discipline the body.

Tests of the Dynamic Field Theory and the Spatial Precision Hypothesis: Capturing a Qualitative Developmental Transition in Spatial Working Memory

This study tested a dynamic field theory (DFT) of spatial working memory and an associated spatial precision hypothesis (SPH). Between 3 and 6 years of age, there is a qualitative shift in how children use reference axes to remember locations: 3-year-olds’ spatial recall responses are biased toward reference axes after short memory delays, whereas 6-year-olds’ responses are biased away from reference axes. According to the DFT and the SPH, quantitative improvements over development in the precision of excitatory and inhibitory working memory processes lead to this qualitative shift. Simulations of the DFT in Experiment 1 predict that improvements in precision should cause the spatial range of targets attracted toward a reference axis to narrow gradually over development, with repulsion emerging and gradually increasing until responses to most targets show biases away from the axis. Results from Experiment 2 with 3- to 5-year-olds support these predictions. Simulations of the DFT in Experiment 3 quantitatively fit the empirical results and offer insights into the neural processes underlying this developmental change.
