SPM in situ data at Patos Lagoon estuary in 4 stations: Feitoria, Marambaia, Praticagem, and Porto Rei - Fernandes (1998)
No full textFernandes (Fernandes, E. H.: Modelling the Hydrodynamics of the Patos Lagoon, Brazil, Ph.D. thesis, University of Plymouth, 2001) aimed to calibrate the hydrodynamic model TELEMAC for the Patos Lagoon for the first time. The author executed SPM field measurements at 4 stations: Feitoria, Marambaia, and Praticagem (between 27-29 October, 1998), and at Porto Rei (between 05-06 November, 1998) and measurements were carried out at the surface, middle depth and bottom using horizontal bottle samplers. These consist of a simple PVC pipe closed at the ends by rubber stoppers and released by a messenger sent from the surface. Sub-samples were stored in plastic bottles for further filtration and determination of SPM content. Samples were filtered through CA filters of 45 μm pore size as in Baumgarten et al. (Baumgarten, M., Rocha, J., and Niencheski, L.: Manual de Análises em Oceanografia Química, FURG, Rio Grande, Brazil, 1996)
A pregação da virtude em Gonçalo Fernandes Trancoso
No full textIn the sixteenth century, in Portugal, Gonçalo Fernandes Trancoso writes his Contos e Histórias de Proveito & Exemplo with pedagogical-moralizing intent, disillusioned at the
dissolution of the customs brought by the overseas conquests. The author makes use of a resource
of the medieval era - the exempla - to show himself as a champion that fights for the values of the
Virtue. The purpose of this article is to analyze how the author mounts his preaching stories by
analyzing the narrative techniques used to show how these stories have become a pleasurable and
uplifting readingNo século XVI, em Portugal, Gonçalo Fernandes Trancoso escreve seus Contos e Histórias de Proveito & Exemplo com intenção pedagógico-moralizante, desiludido ao assistir à dissolução
dos costumes trazida pelas conquistas ultramarinas. Vale-se de um recurso próprio do medievo –
os exemplos – para mostrar-se como paladino que luta pelos valores da Virtude. O objetivo desse
artigo é analisar como o autor monta seus contos de pregação, analisando as técnicas narrativas
utilizadas para mostrar como esses contos tornaram-se leitura prazerosa e edificant
Florestan Fernandes revisited
No full textA AUTORA descreve a biografia intelectual de Florestan Fernandes em três etapas. A primeira, que ela designa "fase científico-acadêmica", abrange o período 1941-1968. A segunda, a "fase político-revolucionária", corresponde aos anos 1970-1986. Por fim, na terceira etapa, que ela chama de "fase solitário-militante" (1986-1995), todas as facetas do itinerário de Fernandes se unem sob o título "intelectual", segundo a definição de Jürgen Habermas.THE AUTHOR describes Florestan Fernandes\u27 intellectual biography in three phases.

Finally, the third phase is what she calls the "lonely militant stage" (1986-1995), in which all facets of Fernandes\u27 itinerary come together under the heading of the "intellectual", in Jürgen Habermas\u27 definition
From acculturation to formation: the role of immigration studies in the work of Florestan Fernandes
No full textHaving received little attention from the interpreters of Florestan Fernandes’ work until recently, the author’s migratory studies, although revisited by specialists in this field, have been the object of implicit or explicit accusations of blame for the poor development of the theme in sociology, and especially at Escola Sociológica Paulista, from the 1940s onwards. This work aims to respond to this “sociology of abandonment” in the interpretation of Fernandes’ work, showing, through a systematic interpretation, that the author’s supposed departure from migratory studies did not happen without the provisions of an accumulative movement, characteristic of the formative model that the author fought for. Tendo recebido pouca atenção dos intérpretes da obra de Florestan Fernandes até pouco tempo, os estudos migratórios do autor, conquanto revisitados por especialistas deste campo, tem sido objeto de acusações, implícitas ou explícitas, de culpa pelo pouco desenvolvimento da temática na Sociologia, e especialmente na Escola Sociológica Paulista, a partir da década de 1940. Este trabalho tem como objetivo responder a esta “sociologia do abandono” na interpretação da obra de Fernandes, mostrando, através de uma interpretação sistemática, que o suposto afastamento do autor relativamente aos estudos migratórios não se deu sem as providências de um movimento acumulativo, próprio do modelo formativo por que pugnava o autor

Long Term Effects of Early Embryonic Ethanol Exposure, on Behavioural Performance and Learning in Zebrafish, Danio rerio
No full textBackground: Fetal alcohol syndrome (FAS) is a devastating disorder whose mechanisms may be best investigated using animal models. Here we present a novel zebrafish FAS model to investigate the effects of low to moderate alcohol exposure during early development on learning.
Methods: At 24-hours postfertilization zebrafish embryos were exposed to low doses of ethanol (external concentrations = 0.00, 0.25, 0.50, 0.75 and 1.00% vol/vol) for a very short duration (2 hours). Upon adulthood associative learning in the zebrafish was tested in a plus maze.
Results: This exposure led to no gross anatomical abnormalities or increased morbidity or mortality. Overall activity was not significantly affected by embryonic ethanol exposure. A trend towards a dose-dependent decrease in learning and memory performance was observed. Conclusions: We suggest that zebrafish will be an appropriate model with which one can analyze the behavioural effects of embryonic alcohol exposure and the mechanisms of the ensuing abnormalities.MAS

Fishing for a Zebrafish model of Fetal Alcohol Spectrum Disorder: The Behavioural Characterization and a Biological Exploration of the Effects of Embryonic Alcohol Exposure on Zebrafish
No full textFetal alcohol spectrum disorder (FASD) is the leading cause of birth defects in the Western world. Individuals with FASD may suffer from physical deformities and /or behavioural and cognitive impairments that are life long, severely reducing their quality of life while placing a financial burden on society. In order to address the aforementioned issues it is necessary to unravel the mechanisms underlying FASD. Animal models can aid in elucidating the mechanisms involved in FASD. The zebrafish possess a number of behavioural and biological characteristics making them a suitable animal model for FASD research. In the past this species has been used to explore the effects of embryonic alcohol exposure (EAE) on physical features. While a few studies have begun to investigate the impact EAE has on social behaviour, these studies utilized a live group of zebrafish (shoal) to assay the behaviour. Previously, I demonstrated that a computerized shoal could be used to study the behavioural deficits associated with EAE; specifically, I found a dose-dependent decrease in social behaviour in exposed fish. The research presented within this thesis represents an expansion of my previous research. Beginning by optimizing the parameters of the computerized stimulus, I was able to demonstrate that the size and the number of fish within the animated shoal effects the social behaviour of experimental fish. Using the optimized social paradigm, I showed that the deficits in social behaviour caused by EAE are stage-specific and that these social impairments do not subside with age. I used high-pressure liquid chromatography to determine whether the changes in social behaviour caused by EAE were accompanied by changes to the dopamine system, finding that EAE did impair the dopaminergic system. I was also successful at developing a new apparatus that is capable of assaying many behaviours in zebrafish, including associative learning and memory.Ph.D
