A transformação e revalorização do espaço do centro histórico de Santos/SP

The city of Santos always had its importance recognised by the respectful role of flowing off the coffee production between the end of 19th and beginning of 20th centuries. All effervescence of this period brought changes to the central area of the city, located near the port. Beginning in the 1970s, some changes in the politics and in the city's urban space made its cafes, theaters, stores and traditional residencies find itselves in decadence imposed by the negligence of the public power. The Historic Downtown of Santos changed to a forgotten and depreciated space and remained that way for many years, reflecting negatively in the preservation of the arquitetonic heritage of the city. The present project aims to analyse the transformation of the current space of the Hitoric Downtown of Santos from the beginning of the 20th century and its recent revaluation through the public politics of the city

Urbanização de favelas: da espontaneidade à cidade formal

O presente Trabalho Final de Graduação analisou projetos de urbanização de favelas em paralelo com algumas urbanizações feitas nos tecido das cidades medievais que também possuem um traçado inicial de origem espontânea. A partir dessa análise, a pesquisa teve como objetivo a busca de experiências técnicas e de gestão, a partir de bases bibliográficas e visitas em campo, nesses locais de diferentes contextos e, a partir disso, discutir soluções urbanísticas que foram bem‐resolvidas ou dificuldades encontradas nas intervenções. A metodologia empregada para a análise baseou‐se na revisão bibliográfica através das bibliotecas da Universidade Estadual Paulista, da Universidade de São Paulo e do Centro de Documentação da Câmara Municipal de Évora, além do acesso a bibliotecas digitais, como a Base Dedalus da Universidade de São Paulo, a Biblioteca Digital da Universidade Federal de Minas Gerais, a BAE da Universidade Estadual de Campinas, a Minerva da Universidade Federal do Rio de Janeiro, a BU da Universidade Federal de Santa Catarina, BIB da Universidade de Évora e a Biblioteca Nacional de Portugal. Os resultados que foram obtidos buscaram responder perguntas como: quais as questões interessantes a se considerar a partir da análise do projeto – técnicas e de gestão? No caso das favelas, quando houve a remoção, isso foi feito por motivos técnicos pertinentes? E a questão da acessibilidade diante de casos de uma ocupação em encostas com acessos perpendiculares às curvas de nível? Como tornar o local acessível a todos? Isso já foi alguma vez pensado e solucionado? Quais as situações que devem ser observadas para se determinar se deverá ter ou não uma realocação das famílias? A partir dessa avaliação buscou‐se criar, ainda que minimamente, subsídios teóricos para novos projetos de urbanização e entender a efetiva importância sociológica na construção do “habitat humano”

Prevalence and severity of caries in 3-12-year-old children from three districts with different fluoridation histories in Araraquara, SP, Brazil

Objective: To determine the prevalence and severity of caries in 3-12-year-old children in three districts of the city of Araraquara, Design: An epidemiological survey was carried out by trained and calibrated examiners in 1995 and 1996, using the WHO diagnostic criteria. Setting: Two districts, Araraquara and Vila Xavier had been fluoridated since 1963 and one, Gavião Peixoto, since 1994. Subjects: The study included 1,191 children from Araraquara, 653 from Vila Xavier and 652 from Gavião Peixoto. Outcome measures: Prevalence of caries, dmft, dmfs, DMFT and DMFS indices. Results: Results showed moderate caries experience in all three districts. Differences between districts in relation to fluoridation history were particularly obvious in primary teeth. In 3-4-year-old children, one third of those in Araraquara and Vila Xavier had some caries experience compared to 58% in Gavião Peixoto. In permanent teeth, 20% or less of the mean DMFT was made up of untreated decay in Araraquara and Vila Xavier whereas in Gaviao Peixoto it made up between 50 and 57% of values in 7-12-year-old children. Conclusions: The prevalence and severity of caries was lower in dentitions of children from the districts fluoridated since 1963. Improvements are likely in the future in Gaviao Peixoto as the benefit of fluoridation continues but additional means of promoting oral health are needed in all three districts.

Historic of therapeutic efficacy of albendazol sulphoxide administered in different routes, dosages and treatment schemes, against Taenia saginata in cattle experimentally infected

The present study aimed to notify the history of albendazole sulphoxide (ALB-SO) and albendazole (ALBZ) efficacy against Taenia saginata cysticercus (Cysticercus bovis) parasitizing experimentally infected bovines. A total of 11 efficacy trials were performed between the years of 2002 and 2010. In order to perform these trials, animals were individually inoculated with 2 x 104 eggs of T. saginata in each study's day zero (DO). For every trial, a positive control group (untreated infected animals) and a negative control group (animals that were neither infected nor treated) were used. ALB-SO or ALB were administered in the different dosages, in different days of treatments. In a last study with this formulation, this active principle was administered orally, mixed with the mineral supplement, on the 60th DPI, in a dosage of 30 mg/kg. In all trials, on the 100th DPI, all animals were euthanized and submitted to the sequenced slicing of 26 anatomical segments (fragments of approximately five millimeters) for the survey of T. saginata cysticercus. With the obtained results it is possible to verify that in the first trials, conducted in 2002, ALB-SO reached, independently of dosage and treatment scheme, efficacies superior to 98% (arithmetic means). The trials conducted in 2005 (2.5 mg/kg on the 30th, 60th, and 90th DPI) obtained values of efficacy all inferior to 60%. In 2008, the trials with 2.5 and 7.7 mg/kg demonstrated efficacy values inferior to 40%, for both dosages and treatment schemes (30th/60th/90th DPI and 60th DPI). When this formulation was administered orally on the dosage of 30 mg/kg on the 60th DPI, the efficacy against T. saginata cysticercus reached 88.28%. ALB administered orally showed efficacy values of 0.0%, 29.88% and 28.64% in the dosages of 5, 10 and 15 mg/kg, respectively, using the treatment schemes described above for each dosage. Based on the results of these trials, conducted in an eight year period (2002-2010) using the sequenced slicing method for evaluating the efficacy of the aforementioned formulations against T. saginata cysticercus, it is possible to observe that, amongst the few molecules used in the chemotherapic treatment against T. saginata larvae, ALB-SO, administered in varied routes, dosages and treatment schemes, the studies conducted in 2008, 2009, and 2010, have a low therapeutic efficacy against C bovis in Brazil, while ALBZ had insignificant efficacy values against T. saginata larvae parasitizing experimentally infected bovines. However, future studies using molecular biology will be necessary to assess whether the difference on the efficacy of the ALB-SO can be related to strain or another specific factor.

Occurrences of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in sheep from four districts of Tocantins state, Brazilian Legal Amazon Region

Toxoplasmosis and neosporosis have been recognized as economically important diseases with considerable impact on the livestock industry. Little is known concerning the occurrence of Toxoplasma gondii and Neospora caninum in sheep from Tocantins state, Brazil. Here, we investigated antibodies against these parasites and associated factors in 182 sheep from Araguaina, Santa Terezinha do Tocantins, Arguianopolis and Palmeiras do Tocantins districts, Tocantins. Sheep sera were assayed for T. gondii and N. caninum IgG antibodies by indirect fluorescence antibody test (IFAT), using cut-off point at a dilution of 1: 40 and 1: 25 respectively. The prevalence of seropositive animal for T. gondii was 13.74% and 13.74% for N. caninum. None of the characteristics studied including reproductive problems, presence of cats, presence of dogs and veterinary care (p>0.05) was associated with occurrence of T. gondii or N. caninum infection. Only breed was identified as associated factor for the occurrence of toxoplasmosis in sheep (p<0.05). The present study is the first report on serum occurrence of T. gondii and N. caninum in sheep from the state of Tocantins, Brazil.

Contemporary and historic factors influence differently genetic differentiation and diversity in a tropical palm

Population genetics theory predicts loss in genetic variability because of drift and inbreeding in isolated plant populations; however, it has been argued that long-distance pollination and seed dispersal may be able to maintain gene flow, even in highly fragmented landscapes. We tested how historical effective population size, historical migration and contemporary landscape structure, such as forest cover, patch isolation and matrix resistance, affect genetic variability and differentiation of seedlings in a tropical palm (Euterpe edulis) in a human-modified rainforest. We sampled 16 sites within five landscapes in the Brazilian Atlantic forest and assessed genetic variability and differentiation using eight microsatellite loci. Using a model selection approach, none of the covariates explained the variation observed in inbreeding coefficients among populations. The variation in genetic diversity among sites was best explained by historical effective population size. Allelic richness was best explained by historical effective population size and matrix resistance, whereas genetic differentiation was explained by matrix resistance. Coalescence analysis revealed high historical migration between sites within landscapes and constant historical population sizes, showing that the genetic differentiation is most likely due to recent changes caused by habitat loss and fragmentation. Overall, recent landscape changes have a greater influence on among-population genetic variation than historical gene flow process. As immediate restoration actions in landscapes with low forest amount, the development of more permeable matrices to allow the movement of pollinators and seed dispersers may be an effective strategy to maintain microevolutionary processes.
