Air pollution assessment over Po valley (Italy) using satellite data and ground station measurements

Due to their effect on human health, the study of atmospheric pollutants is an important concern in the Po valley – northern Italy – one of the main industrialized and populated areas of the country. Our work focuses on the applicability of satellite Aerosol Optical Depth (AOD) retrievals in support of air quality monitoring and assessment in urban environments within the Po valley. This has been accomplished by using the implementation of the International MODIS/AIRS Processing Package (IMAPP) Air Quality Applications software, IDEA-I (Infusing satellite Data into Environmental Applications-International) over the Po valley study area. IDEA-I is a globally configurable software package that uses either Terra or Aqua MODerate resolution Imaging Spectro-radiometer (MODIS) AOD product retrievals to identify local domains of high values of aerosol. For our specific analyses, IDEA-I has been used over the large European domain, centred over the Po Valley. One year (2012) of MODIS AOD product retrievals from MODIS on board NASA’s Terra (MOD04) or Aqua (MYD04) satellite has been considered using IDEA-I in a retrospective study. These retrieved data have been also compared with the Particulate Matter (PM 10 ) measurements from the Italian Agency for Environmental Protection (ARPA) ground-based network stations. The acceptable results obtained by the correlation PM 10 – AOD suggest the satellite AOD as a good substitute for monitoring air quality over the Po valley domain. Yet the 10 km resolution of MODIS – AOD product is considered too large for air quality studies at urban scale. Recently, a new Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm has been developed for MODIS which provides AOD data at 1 km of spatial resolution. We have evaluated ability of MODIS product MOD04 and MAIAC products to characterize the spatial distribution of aerosols in the urban area through comparison with surface PM 10 measurements. Using MAIAC data at 1 km, we have examined the relationship between PM 10 concentrations, AOD, and AOD normalized by Planetary Boundary Layer (PBL) depths obtained from NOAA National Center for Environmental Prediction (NCEP) Global Data Assimilation System (GDAS), for the same period of analysis. Results show that the MAIAC retrieval provides a high resolution depiction of the AOD within the Po Valley and performs nearly as well in a statistical sense as the standard MODIS retrieval during the time period considered. Results also highlight that normalization by the analyzed PBL depth to obtain an estimate of the mean boundary layer extinction is needed to capture the seasonal cycle of the observed PM 10 over the Po Valley

O rastro do harmatão: gerações em conflito na "African Trilogy" de Chinua Achebe (1958-1964)

The work that follows aims to analyze the African Trilogy of Chinua Achebe, aiming at the moments of generational conflicts in the narrative through the methodology of discourse analysis, thus detecting the political and nationalist pretensions of the author within the time of publication of the works. We articulate the novels in a way that goes back from the most recent time (the 1950s) to the most remote (the end of the 19th century), going through fundamental themes in the narratives, such as the permanence of colonial pretensions, the project of a colony nation , socio-political negotiations, feeling of lack of unity, in addition to the need to show the other side, which belongs to the indigenous, in this case the igbo people. Through the adoption of literary aesthetics of the colonizer (in this case, the tragic genre), we concluded that the author had the object of bringing the example to the generations who read his work, in order to create questions about what should be the future of Nigerian democracy.Pesquisa sem auxílio de agências de fomentoTrabalho de Conclusão de Curso (Graduação)O trabalho que segue tem o objetivo de analisar a African Trilogy de Chinua Achebe, visando aperceber os momentos de conflitos geracionais na narrativa através da metodologia da análise de discurso, pretendendo detectar assim as pretensões políticas e nacionalistas do autor no âmbito da época de publicação das obras. Articulamos os romances de maneira a voltar do tempo mais recente (os anos de 1950) até o mais remoto (o final do século XIX), perpassando por temas fundamentais nas narrativas, como a permanência das pretensões coloniais, o projeto de uma nação-colônia, as negociações sócio-políticas, sentimento de carência de unidade, além da necessidade de se mostrar o outro lado, o que pertence ao indígena, no caso o povo ibo. Através da adoção de estéticas literárias do colonizador (no caso, o gênero trágico), concluímos que o autor tinha o objeto de trazer o exemplo para as gerações que liam o seu trabalho, de forma a criar questionamentos sobre o que deveria ser o futuro da democracia nigeriana

A new simplified approach for simultaneous retrieval of SO2 and ash content of tropospheric volcanic clouds: an application to the Mt Etna volcano

A new procedure is presented for simultaneous estimation of SO2 and ash abundance in a volcanic plume, using thermal infrared (TIR) MODIS data. Plume altitude and temperature are the only two input parameters required to run the procedure, while surface emissivity, temperature, atmospheric profiles, ash optical properties, and radiative transfer models are not necessary to perform the atmospheric corrections. The procedure gives the most reliable results when the surface under the plume is uniform, for example above the ocean, but still produces fairly good estimates in more challenging and not easily modelled conditions, such as above land or meteorological cloud layers. The developed approach was tested on the Etna volcano. By linearly interpolating the radiances surrounding a detected volcanic plume, the volcanic plume removal (VPR) procedure described here computes the radiances that would have been measured by the sensor in the absence of a plume, and reconstructs a new image without plume. The new image and the original data allow computation of plume transmittance in the TIR-MODIS bands 29, 31, and 32 (8.6, 11.0 and 12.0 \u3bcm) by applying a simplified model consisting of a uniform plume at a fixed altitude and temperature. The transmittances are then refined with a polynomial relationship obtained by means of MODTRAN simulations adapted for the geographical region, ash type, and atmospheric profiles. Bands 31 and 32 are SO2 transparent and, from their transmittances, the effective ash particle radius (Re), and aerosol optical depth at 550 nm (AOD550) are computed. A simple relation between the ash transmittances of bands 31 and 29 is demonstrated and used for SO2 columnar content (cs) estimation. Comparing the results of the VPR procedure with MODTRAN simulations for more than 200 000 different cases, the frequency distribution of the differences shows the following: the Re error is less than \ub10.5 \u3bcm in more than 60% of cases; the AOD550 error is less than \ub10.125 in 80% of cases; the cs error is less than \ub10.5 gm 122 in more than 60% of considered cases. The VPR procedure was applied in two case studies of recent eruptions occurring at the Mt Etna volcano, Italy, and successfully compared with the results obtained from the established SO2 and ash assessments based on look-up tables (LUTs). Assessment of the sensitivity to the plume altitude uncertainty is also made. The VPR procedure is simple, extremely fast, and can be adapted to other ash types and different volcanoes

Diagnóstico da gestão do conhecimento: estudo de caso em uma instituição pública brasileira

A administração pública tem passado por transformações e desafios na busca por novos modelos de gestão para atingir seus objetivos e oferecer um atendimento com eficiência e qualidade aos cidadãos, que estão cada vez mais exigentes. Nesse contexto a gestão do conhecimento surge como estratégia para alcance dos objetivos institucionais e melhoria da gestão organizacional. Este estudo insere-se na área da gestão do conhecimento, cujo objetivo foi identificar como é a gestão do conhecimento em uma instituição pública brasileira, através do diagnóstico da gestão do conhecimento – DGC, com o instrumento de diagnóstico proposto por Bukowitz & Williams (2002). O método empregado foi o estudo de caso, de natureza descritiva, cuja coleta de dados foi realizada através da aplicação de um questionário estruturado. Através da pesquisa, foi possível identificar que a organização, apesar de não possuir um programa estruturado de GC, está a gerir seu conhecimento de forma moderada, no âmbito geral do processo. Identificou-se ainda que o passo “Avalie” é o que exige maior atenção dos gestores para sua melhoria. Constatou-se também que, não há disparidade significativa entre a percepção dos gestores e dos servidores técnico-administrativos em educação no que diz respeito à gestão do conhecimento. Os resultados podem contribuir para que os gestores reconheçam o conhecimento como recurso essencial e insiram em seu planejamento estratégico a GC, com a prática de ações para uma gestão do conhecimento mais efetiva, visando a melhoria da gestão organizacional e de seus processos como um todo, em benefício da sociedade.The public administration has undergone transformations and challenges in the search for new management models to reach its objectives and to offer a service with efficiency and quality to the citizens, who are more and more demanding. In this context, knowledge management emerges as a strategy for achieving institutional objectives and improving organizational management. This study is part of knowledge management, whose objective was to identify how is the knowledge management in a Brazilian public institution, through the diagnosis of knowledge management - DGC, with the diagnostic tool proposed by Bukowitz & Williams (2002). The method used was the case study, of a descriptive nature, whose data collection was performed through the application of a structured questionnaire. Through the research, it was possible to identify that the organization, although it does not have a structured program of KM, is managing its knowledge in a moderate way, in the general scope of the process. It was also identified that the step "Evaluate" is what requires greater attention of the managers for its improvement. It was also verified that, there is no significant disparity between the perception of the managers and the technical-administrative servants in education regarding to knowledge management. The results can contribute to the managers to recognize knowledge as an essential resource and to insert in their strategic planning the KM, with the practice of actions for a more effective knowledge management, aiming at improving the organizational management and its processes as a whole, for the benefit of the society
