Comunicação e cidadania às margens do São Francisco: os correspondentes populares da Diocese de Juazeiro Ba (19882008)

Este trabalho apresenta um estudo de caso, apoiado em pesquisa bibliográfica, pesquisa documental e entrevistas semiestruturadas, sobre o trabalho dos correspondentes populares do Setor de Comunicação e Audiovisual (SEDICA) da Diocese de Juazeiro na Bahia, entre os anos, 19882008. Objetivo principal é analisar o desenvolvimento da experiência, levando em consideração o seu caráter comunitário, às relações estabelecidas entre os vários parceiros nos processos comunicativos e o significado que a experiência têm para os correspondentes envolvidos. Demonstrouse que o trabalho do SEDICA merece destaque porque mantêm como opção uma comunicação que valoriza os ouvintes e, a partir deles, constrói uma programação de caráter crítico e participativo. Sua ligação com a realidade da diocese é garantida porque suas fontes vivem a vida dura do semiarido nordestino o que aproxima os conteúdos dos programas dos moradores, que superam as dificuldades de forma criativa, tal qual os correspondentes superam suas dificuldades na produção das notícias que devem enviar periodicamente ao setor de comunicação.(AU)

NOx storage-reduction characteristics of Ba-based lean NOx trap catalysts subjected to simulated road aging

In order to study the effect of washcoat composition on lean NOx trap (LNT) aging characteristics, fully formulated monolithic LNT catalysts containing varying amounts of La-stabilized CeO2 (5 wt% La2O3) or CeO2-ZrO2 (Ce:Zr = 70:30) were subjected to accelerated aging on a bench reactor. Subsequent catalyst evaluation revealed that aging resulted in deterioration of the NOx storage, NOx release and NOx reduction functions, whereas the observation of lean phase NO2 slip for all of the aged catalysts indicated that LNT performance was not limited by the kinetics of NO oxidation. After aging, all of the catalysts showed increased selectivity to NH3 in the temperature range 250–450 °C. TEM, H2 chemisorption, XPS and elemental analysis data revealed two main changes which can explain the degradation in LNT performance. First, residual sulfur in the catalysts, present as BaSO4, decreased catalyst NOx storage capacity. Second, sintering of the precious metals in the washcoat was observed, which can be expected to decrease the rate of NOx reduction. Additionally, sintering is hypothesized to result in segregation of the precious metal and Ba phases, resulting in less efficient NOx spillover from Pt to Ba during NOx adsorption, as well as decreased rates of reductant spillover from Pt to Ba and reverse NOx spillover during catalyst regeneration. Spectacular improvement in LNT durability was observed for catalysts containing CeO2 or CeO2-ZrO2 relative to their non-ceria containing analog. This was attributed to (i) the ability of ceria to participate in NOx storage/reduction as a supplement to the main Ba NOx storage component; (ii) the fact that Pt and CeO2(-ZrO2) are not subject to phase segregation; and (iii) the ability of ceria to trap sulfur, resulting in decreased sulfur accumulation on the Ba component.

Comparison of Ba/Ca and d18OWATER as freshwater proxies: a multi-species core-top study on planktonic foraminifera from the vicinity of the Orinoco River mouth

Past river run-off is an important measure for the continental hydrological cycle and the as-sessment of freshwater input into the ocean. However, paleosalinity reconstructions applying different proxies in parallel often show offsets between the respective methods. Here, we compare the established foraminiferal Ba/Ca and d18OWATER salinity proxies for their capability to record the highly seasonal Orinoco freshwater plume in the eastern Caribbean. For this purpose we obtained a data set comprising Ba/Ca and d18OWATER determined on multiple spe-cies of planktonic foraminifera from core tops distributed around the Orinoco river mouth. Our findings indicate that interpretations based on either proxy could lead to different conclu-sions. In particular, Ba/Ca and d18OWATER diverge in their spatial distribution due to different governing factors. Apparently, the Orinoco freshwater plume is best tracked by Ba/Ca ratios of G. ruber (pink and sensu lato morphotypes), while d18OWATER based on the same species is more related to the local precipitation-evaporation balance overprinting the riverine freshwater contribution. Other shallow dwelling species (G. sacculifer, O. universa) show a muted response to the freshwater discharge, most likely due to their ecological and habitat prefer-ences. Extremely high Ba/Ca ratios recorded by G. ruber are attributed to Ba2+-desorption from suspended matter derived from the Orinoco. Samples taken most proximal to the freshwater source do not show pronounced Ba/Ca or d18OWATER anomalies. Here, the suspension loaded freshwater lid developing during maximum discharge suppresses foraminiferal populations. Both proxies are therefore biased towards dry season conditions at these sites, when surface salinity is only minimally reduced.

Stable isotopes and Mg/Ca ratios on foraminifera and Ba/Ca ratios of sediment core SK168/GC-1

The past variability of the South Asian Monsoon is mostly known from records of wind strength over the Arabian Sea while high-resolution paleorecords from regions of strong monsoon precipitation are still lacking. Here, we present records of past monsoon variability obtained from sediment core SK 168/GC-1, which was collected at the Alcock Seamount complex in the Andaman Sea. We utilize the ecological habitats of different planktic foraminiferal species to reconstruct freshwater-induced stratification based on paired Mg/Ca and d18O analyses and to estimate seawater d18O (d18Osw). The difference between surface and thermocline temperatures (delta T) and d18Osw (delta d18Osw) is used to investigate changes in upper ocean stratification. Additionally, Ba/Ca in G. sacculifer tests is used as a direct proxy for riverine runoff and sea surface salinity (SSS) changes related to monsoon precipitation on land. Our delta d18Osw time series reveals that upper ocean salinity stratification did not change significantly throughout the last glacial suggesting little influence of NH insolation changes. The strongest increase in temperature gradients between the mixed layer and the thermocline is recorded for the mid-Holocene and indicate the presence of a significantly shallower thermocline. In line with previous work, the d18Osw and Ba/Ca records demonstrate that monsoon climate during the LGM was characterized by a significantly weaker southwest monsoon circulation and strongly reduced runoff. Based on our data the South Asian Summer Monsoon (SAM) over the Irrawaddyy strengthened gradually after the LGM beginning at ~18 ka. This is some 3 kyrs before an increase of the Ba/Ca record from the Arabian Sea and indicates that South Asian Monsoon climate dynamics are more complex than the simple N-S displacement of the ITCZ as generally described for other regions. Minimum d18Osw values recorded during the mid-Holocene are in phase with Ba/Ca marking a stronger monsoon precipitation, which is consistent with model simulations.

A economia solidária sob a perspectiva do desenvolvimento endógeno: o caso da cooperativa de coleta seletiva e reciclagem amigos do planeta - Lauro de Freitas/BA (2004/2013)

In recent decades, the collective leadership of the Solidary Economical Enterprises (ESS) that are active in providing collection and recycling services, has been presented as a proposal for the organization of urban space with the creation of new enterprises and solidarity production chains. Are activities that have gained a new stimulus to the creation of the National Secretariat of Solidarity Economy and the National Policy on Solid Waste that assigned a leading role in these social actors. These experiences contribute to building a participatory development path, resembling with the pluralistic perspective of development of the Indian economist Amartya Sen, that goes beyond the simplistic design of the increased income, focusing on the process of expanding freedoms that people enjoy. The aim of this work is to situate the perspective of endogenous development with the Collection Services segment and Material Recycling in the field of Solidarity Economy, through the analysis of the experience of the Cooperative of Selective Collection and Recycling Friends of the planet, located in the municipality of Lauro to Freitas - BA, from 2004 to 2013. for this the following procedures were adopted: analysis of the main contributions of the international literature on the phenomenon of pluriactivity; review of national literature that analyzes the emergence and evolution of the projects of solidarity economy in Brazil; bibliographical and documentary research; and socio-economic evaluation of the EES. The guiding problem of this work, understandably, is: what is the meaning of endogenous perspective with the Materials Collection and Recycling Services segment in the field of Solidarity Economy? It starts with the hypothesis that the development of these practices requires an environment that removes the main sources of deprivation involving the conditions of existence of these enterprises. The results show that not enough development to be built with the participation of social actors, but there are minimally necessary conditions for such experiences can take hold in order to achieve their goals. Thus, not only is it a strictly economic issue, but requires political actions for a process of social transformation.
