Patrimônio natural e cultural em uma área de expansão urbana: o caso da Granja Carolina - Cotia/Itapevi - SP

El objectivo del trabajo fue analisar los impactos ambientales y sociales de las politicas publicas y de la especulación imobiliária sobre las áreas remanescientes de la vegetación nativa en la Granja Carolina. Con base en la definición del Património Cultural y Património Natural, fue abordado el proceso de formación desa región oeste de la metrópole, especificamente en lo entorno de la Granja Carolina situada entre los municipios de Cotia y Itapevi. La identificación deses problemas y la realización de un estudio sobre el modelo de la ocupación y el uso de lo solo urbano permitiu identificar su grau de vulnerabilidad a los impactos traydos por la expansión urbana. Para lo entendimiento de tais cuestiones analisamos lo proyecto y lo EIA/RIMA de um empreendimiento imobiliario que si pretendia instalar em la área de estúdio. Entendese también que el planejamiento territorial debe conter el debate sobre la protección del Património Cultural y Natural, cuestiones también pertinentes em el campo de la Geografía

Determinação da freqüência natural de eixos utilizando o software excel

This work aims to determine the first natural frequency of rotation shaft by using a basic software, Excel, and to compare it to the values obtained in laboratory. When an axle is submitted to a rotation, depending on the rotational frequency used, the axle can enter a state of resonance, in which the amplitude of vibration becomes rather high. The frequencies in which the resonance is observed depends on several parameters of the axle, including the number of concentrated masses associated to the axle. Thus, to obtain a computer program of easy use and access, which can preview the frequency of resonance of an axle in rotation with ‘n’ numbers of concentrated masses it has been studied how the frequency varies with each of these parameters. The computer program and the analyses have been made using the Rayleigh Method, which allowed the transformation of a continuous system to discrete through the theory of finite elements, which has proved that, the bigger the number of divisions of the shaft taken into consideration in the calculus of the natural frequency, the more this value gets close to the real value. The results obtained have been considered satisfactory once these have gotten close to the theoretical results expected

Chave de identificação interativa de múltiplas entradas para espécies da família Lauraceae da Reserva Natural Vale, Linhares - ES

Foi elaborada uma chave interativa de múltiplas entradas para a identificação de 50 espécies da Família Lauraceae presentes na Reserva Natural Vale, Linhares-ES. Desenvolvida a partir da versão livre do Programa Lucid® 3.3, apresenta caracteres botânicos de marcação livre e não sequencial, que elimina as espécies as quais não atendem aos critérios selecionados até a identificação do material. Para tanto foi confeccionada uma matriz de caracteres relacionados aos táxons. Foram incluídas ilustrações no final do trabalho já que a versão utilizada do programa compromete a resolução dessas na própria chave. Há uma cópia da chave com o instalador do programa e instruções para uso no CD-ROM entregue junto com o trabalho. Futuramente estará hospedada no site do programa. A versão apresentada no trabalho é preliminar e será concluída posteriormente com a versão paga do programa. A utilização das chaves interativas facilita e dinamiza o processo de identificação dos táxons, contribuindo para a difusão do conhecimento biológico e de programas voltados ao reconhecimento e conservação da biota

Enzimas de biotransformação em tilápia (Oreochromis niloticus) exposta ao hormônio natural 17b-estradiol

Among the sexual hormones the estrogens are receiving major attention due to their biological activity. Such biological response is atributed to the best conformation recognized by their receptors, resulting in maximum responses. The estrogens are also considered responsible for most of disruptor´s effects caused by their presence in aquatic ecosystems. The 17β-estradiol hormone is produced by vertebrates during the reproductive phase of their lives and its presence has been detected in superficial waters. The objective of this study was to evaluate the cause-effect of tilapia exposition to the hormone 17β-estradiol through the analysis of biotransformation enzymes in liver and gills, complemented with the quantification of 17β-estradiol and estrone in water samples collected from fish ponds integrated to swine production. The present study was conducted under laboratory conditions, in a randomized experimental design with three levels of 17β-estradiol (E2) (0, 5, 15 µg L-1), with three replicates. After 7 days of exposure time, liver and gills were extracted to analyze three isoforms of cytochrome P450: EROD, BROD, PROD and the activity of Glutathione S-Transferase (GST). The results showed that the EROD activity (CYP1A), normally induced by the metabolism of aromatic compounds, did not present statistical differences among the treatments exposed to E2, what means that the hormone did not induce isoform 1A in fish under these particular experimental conditions. PROD activity was significantly altered in both concentrations, by means of 5 and 15 µg L-1, when compared to control. This result can indicate an important role of PROD on the metabolism of E2 present in water. Regarding to the BROD activity, it could be observed differences statistically significant between control and both groups of treatments. Two or more CYP isoforms can contribute to the metabolism of the same compound, what makes BROD a candidate as a next bioindicator of the exposure to E2 in aquatic ecosystems. Analysis of variance could confirm the effect of E2 statistically significant on the GST activity in liver tissues with >90% of significance (Prob>F = 0.0753). Furthermore, it was possible to observe that the values of GSTs activities in liver and gills in both, control and treatments, follow a tendency, that means, enzymatic activity in gills increase as the increasing of the activity in the liver tissues. In this study, the 17β–estradiol was found in measurable concentrations in three sampled points, and these values were similar to the findings of other authors at different locations in Brazil. In addition, those values are much higher than the minimum concentration that presented observable effects (10 ng L-1).

Caracterização físico-química e sensorial de vinhos brancos da região noroeste de São Paulo

Brazilian wines are appreciated by consumers for having fruity odor and taste which are typical from Vitis labrusca cultivars. The rusticity of these cultivars, the winemaking and the physicochemical properties are some of the key factors to obtain a quality beverage. In this context, the aim of this article was to analyze the quality of three white wines from wineries located in northwest region of São Paulo state by determining physicochemical properties and sensory profile. Data were analyzed by statistical tests and by Principal Component Analysis (PCA). It was possible to observe statistical differences (P<0,05) in most physicochemical properties. Furthermore, the PCA showed that the attributes body and color significantly explained the variance of the first and second component, respectively, higlighting the Vitis vinifera wine. Thus the connection between the physicochemical and sensory properties of white wines was important for characterization of these beverages produced in the northwest of São Paulo.

Diversidade de Formicidae (Hymenoptera) em um fragmento de Floresta Estacional Semidecídua no Noroeste do Estado de São Paulo, Brasil.

(Ant diversity (Hymenoptera) in a fragment of Semidecidual Seasonal Forest in Northwest of São Paulo State, Brazil). Due to scarce knowledge about ant fauna from Northwestern São Paulo State, the present study aimed to know the taxonomic diversity of Formicidae, relating the results to climatic variation along of one year. The samples were gotten monthly, using pitfall traps. It was sampled 25 species of 15 genera and seven subfamilies. Myrmicinae was the sampled richest subfamily, follows by Formicinae and Ponerinae. According Wilcoxon test, the species richness, equability and diversity estimated by Simpson index were significantly higher in the rain season. The obtained results suggest that the abundance of ants is significantly related to the temperature variation, while the ant assemblage structure is related to thermal and pluviometric variations.
