Assessment of Daphnia magna as a toxicity bioindicator for wastewaters
Toxicity tests on complex wastewater effluents have been considered as an important complement to emission limit values (ELV) based on physico-chemical and microbiological parameters in recent years. However, relatively few studies have been conducted so far evaluating the toxicity of effluents with aquatic organisms, and it remains unclear which test species should be used in such evaluations. The first aim of this dissertation was therefore to assess the potential of the crustacean Daphnia magna as a bioindicator for the toxicity of a domestic effluent disinfected with peracetic acid (PAA), a disinfect that has received increasing attention in recent years as an alternative disinfectant for chloride. To this end, bioassays were performed with D. magna on the secondary effluent from the WWTP of Beirolas, with and without disinfection by 5 mg.L-1, 10 mg.L-1 and 15 mg.L-1 PAA. These PAA concentrations were selected since they were shown in a parallel MSc study to have high removal efficacy of coliform and faecal bacteria.
Exposure to the secondary effluent without disinfection caused no mortality or immobility on the organisms. Although the disinfected effluent adhered to all the standards set in current Legislation, even the lowest PAA concentration resulted in 100% daphnid mortality within 48h. Subsequently, efforts should be made to evaluate whether lower PAA concentrations or a longer residual time after PAA treatment may ensure disinfection efficacy without exerting toxicity to aquatic organisms like D. magna.
The second aim of this dissertation was to compare the sensitivity of D. magna to wastewater with that of other species commonly used in bioassays. This was done to evaluate which test species are the most appropriate for use in wastewater toxicity testing. To this end, a literature search was conducted by collecting data from papers where the toxicity of effluents was tested to D. magna and at least one other species. This thus allowed to evaluate the relative tolerance (Trel) of these species as compared to D. magna.
The taxonomic groups that appeared to be more sensitive to effluents than D. magna were bacteria and rotifers. On the other hand, macrophytes, insects and fish were found to be generally less sensitive than D. magna. Since no single species was aways the most sensitive species to the wide range of effluents (e.g. different sources, compositions and sampling periods) included in the dataset, a test battery including species from different taxonomic groups is recommended for effluent testing

The paper closes with some final remarks on the lessons that can be drawn from the Brazilian experience
Guias de viagem como gênero editorial
Estudo sobre a natureza editorial dos guias de viagem, obras escritas de caráter utilitário que reúnem informações sobre determinado local – cidade, região, paÃs ou continente – com o objetivo de instruir os turistas que visitam este mesmo local. Com a popularização mundial das viagens de lazer, o segmento de publicações voltadas para o turista experimenta um desenvolvimento acelerado dentro do mercado editorial. Especialmente no Brasil, inexistem estudos que abordem os guias de viagem de um ponto de vista editorial, malgrado a importância crescente deste tipo de obra. A partir de uma revisão da literatura e de um exame
detalhado de diversas coleções, é proposto e defendido que os guias de viagem são determinados por quatro parâmetros – público, categorização, estruturação e recomendação – que os tornam produtos culturais únicos dentro do conjunto do mercado editorial para o turista. É produzida ainda uma sugestão de classificação para o gênero, e uma análise acerca da linguagem em guias de viagem
Febre persistente e expectoração hemoptóica – caso clÃnico
Foreign body aspiration (FBA) is a common and serious problem in children. Considering that signs and symptoms can be non-specific and subtle, it is of utmost importance to recognize vulnerable patient groups, combine an accurate history with complete physical examination, and follow a structured diagnostic approach towards correct diagnosis. In the present case, a high index of suspicion was essential to prevent a delay in FBA diagnosis, discuss the appropriate management strategy and improve patient outcomes.info:eu-repo/semantics/publishedVersio

36. Diagnóstico do cancro do pulmão: comparação da expectoração pósbroncoscopia, lavado, escovado e biópsia brônquicos
Lung cancer is one of the most important respiratory diseases. The flexible bronchoscopy (FBC) is an exam widely used in its diagnosis and staging and, in specific cases, its treatment. There are several diagnostic bronchoscopies techniques currently used. The most common are the bronchial washing (BW), brushing (BBR) and biopsy (BB).It was our aim to evaluate the diagnostic yield of these three techniques, as well as, the post-bronchoscopy sputum cytology (PBSC), at presence of a suspicious visible endoscopy lesion of lung cancer. From September of 2001 to February of 2003, 56 FBC were carried out on patients with clinical history and suggestive endoscopy injury of lung cancer (hyperaemia/infiltration/tumour). In all patients we performed BW, BBR and BB and, always if it was possible, PBSC. The patients were excluded when the 4 applied diagnostic techniques were negative for malignancy. The results had been classified as positive, negative or suspected.The diagnosis of lung cancer, through at least one of three bronchoscopies techniques or PBSC, was obtained in 44 patients (78,6%). In the total of these patients the diagnostic yield from BW was 56,8%, from BBR 79,5%, from BB 95,5%. The yield from PBSC was 28,6% (n=42). The three techniques were simultaneously positive for malignancy in 52,3% of the total, being concordant, in terms of specification of the histologic type, in 69,6%. The BBR and the BB were both positive in 22,8% (70% agreement) and BW and BB in 4,5% (100% agreement). The BBR was the only positive diagnostic technique in 4,5% of the cases and the BB in 15,9%. The BW and the PBSC were never the only positive result.Of the 7 cases where the BBR was positive for malignancy but did not allow the specification of the histology type, 5 (71, 4%) were clarified by the BB. In turn, of the 7 cases where the BB was not diagnostic of the specific type of cancer, 3 were defined by BBR (42,9%).The endoscopy aspect had been described as infiltration in 63.4% cases and the remaining as tumour. The BW was more frequently positive in presence of infiltration in comparison to tumour (64% versus 36%). It were not verified significant differences in relation to the BBR and BB.In literature there continues to exist some controversy about the diagnostic value of the BW, BBR, BB and PBSC in lung cancer. This work clearly shows that the BB is the most cost-effective technique, but the values obtained for BW and BBR were also relevant. However, it is to be stressed that neither the BW nor the PBSC constituted at any time the only positive diagnostic technique for malignancy, neither did they contributed for the clarification of the histologic type. The BBR only increased by 3,5% the total diagnostic yield

Hate observed : Between an ethnography of neo-nazism and the biography of David Lane
Orientador: Maria Suely KofesTese (doutorado) - Universidade Estadual de Campinas, Instituto de Filosofia e Ciências HumanasResumo: A investigação antropológica proposta objetiva analisar a biografia do lÃder neonazista David Éden Lane, mapear os grupos neonazistas nos Estados Unidos, seu processo de nazificação, o lugar que esses grupos construÃram para Lane e como ele legitimou esse lugar para si, em especial por meio de seus escritos. Para tanto, a apreciação biográfica se uniu a etnografia. Algumas questões cruciais surgiram dessa análise: entre elas, me deterei, por escolha, na bidimensão (biológica e mitológica) da construção da narrativa neonazista, no mapeamento dos grupos neonazistas, oriundo do trabalho etnográfico, da observação do ódio como centro da vida social do ativismo e da noção de pessoa construÃda pelo movimento. Palavras chaves: neonazismo, narrativas, discurso de ódioAbstract: The proposed anthropological investigation aims to analyze the biography of neo-nazi leader David Éden Lane, to map the neonazi groups in the United States, their nazification process, the place these groups built for lane and how he legitimated this place for himself, especially through his writings. To that end, the biographical appraisal united with the ethnography. Some crucial questions emerged from this analysis: among them, I will focus, by choice, on the bidimension (biological and mythological) of the construction of the neo-nazi narrative and on the mapping of the neo-nazi groups, mapping which originated from the ethnographical work, the observation of hatred as the centre of the activism's social life and from the notion of person constructed by the movementDoutoradoAntropologia SocialDoutora em Antropologia Socia
