The city of Ilha Comprida, located on the Environmental Protection Area Cananéia-Iguape-Peruíbe (APA CIP) and Lagoon Estuary Complex of Iguape-Cananéia-Paranaguá, is located at the southern end of the coast of the state of São Paulo. Ilha Comprida is a progradational barrier consists predominantly of sandy sediments of the Quaternary Period. Bibliographic and cartographic surveys demonstrate a large amount of sediments in the last centuries, leading to the expansion of the island in hundreds of meters towards SW / NE. The island has been suffering intense morphological change in the northeast corner - NE, growing 35 meters per year. The objective of this study is to measure and analyze the floristic diversity found in its extreme NE, recent accumulation area of sediment, comparing the results with data obtained in equivalent segment, located on the edge SW, agradation preterit area. Given this reality, we chose to assess how the process of ecological succession respond to these dynamics. That is, if we think of ecological succession, NE end (latest) is assumed to possess plant species in the initial stage of succession as well as the SW portion. However, it is assumed certain differentiation between species in both areas, and less diversity in the first case (NE). Using the method of fixed installments adopted for similar quadrants, we attempted to measure and analyze the floristic diversity of the NE end and compare the data obtained in the field with those listed for the SW end. The results confirmed the hypothesis of the research, and prompted several questions that point to the need for further deepening research on this theme

Observa-se como estratégia mundial para a conservação da biodiversidade a criação de unidades de conservação. No Brasil, especificamente no Estado de São Paulo, devido a intensa degradação da Mata Atlântica, verifica-se a criação de unidades de proteção integral, a fim de se preservar de modo restrito os recursos naturais que ainda lhe restam. Na cidade de Ribeirão Preto, uma região com alto desempenho agrícola e intensa expansão urbana, constata-se a presença de uma Estação Ecológica (EERP), fragmento florestal de 154,16 ha, altamente isolado e fragmentado. Assim, a EERP e sua zona de amortecimento (ZA) vêm sendo fortemente pressionada pela expansão urbana e agrícola da região, comprometendo a sua integridade ecossistêmica. Dentre os impactos negativos gerados destacam-se: alta especulação imobiliária e o intenso cultivo de monoculturas, que contribuem para a degradação do solo nas regiões do entorno. A fim de se reduzir tais impactos, o presente trabalho buscou apresentar um prognóstico de planejamento ambiental para a ZA da EERP, a qual se encontra altamente impactada, segundo os critérios definidos por Ranieri (2004). Desse modo, criou-se cenários ideais para a preservação dos recursos naturais do local

A metal coping may undergo changes during porcelain firing, which compromises its marginal adaptation. The use of NiCrTi alloy proposes to minimize this effect through the high melting point of titanium present in its composition. This study evaluated the influence of porcelain firing cycle on the marginal adaptation of NiCrTi copings in different preparation designs. Forty standardized metal dies were fabricated with the following combinations finish line/convergence of the axial walls: 1) shoulder/6°; 2) shoulder/20°; 3) sloping shoulder/6°; 4) sloping shoulder/20°. On each die a metal ceramic restoration coping was made. The die/coping set was stabilized with orthodontic elastics, divided into four equidistant areas with three measurement points each and a cementation pressure was simulated. The measurements were taken under a stereomicroscope (32×). After the first measurement, the copings were submitted to sintering cycles simulating porcelain application. For repeated measurements, the same procedures described above were performed. Data were submitted to Student’s-t test, 1-way ANOVA and Tukey´s test (α = 0.05). Adaptation means (µm) before and after porcelain firing in different preparations were: 1) 111.92 and 127.31; 2) 124.15 and 135.48; 3) 122.19 and 138.77; 4) 166.09 and 186.72; respectively. The porcelain firing impaired adaptation, regardless of the preparation design. The preparation in a 20° sloping shoulder provided a worse adaptation when compared with preparations that had 6° and 20° shoulder, which were statistically equal. The 6° sloping shoulder was statistically equal to the other three preparation designs.

The aim of this study was to adapt the BriefCOPE Inventory for Portuguese-speaking university students. We evaluate the Portuguese BriefCOPE psychometrics qualities and estimated the BriefCOPE factorial invariance in Brazil and Portugal. The data collected from a sample of 1573 students of both nationalities did confirm the 14-factor structure of the BriefCOPE and showed both factorial, convergent and discriminant related validities. However, the factor model did not show invariance across countries indicating that the use of the Portuguese version of the BriefCOPE cannot be bailed for comparisons of scores of inter-countries' student coping.

The present project consists in an exploratory research centralized on the main patterns of the database of treaties registered by the Secretariat of the United Nations due to its obligations stated at Article 102 of the organization?s Charter. More specifically its purpose is to adapt and apply computer visualization tools to this database. The visualization tools developed here aim the exploration, discovery and communication of relevant features to International Relations research. These tools allow the manipulation of selected variables in the database, such as dates, participant actors and treaties subject. The visual representations furthermore facilitate the analysis of several dimensions of subsets chosen by the user, such as qualitative, temporal and geographic distribution. These proceedings help bring hidden patterns to the surface. The discussion about the limits of these tools has also a central place on this research. We listed and analyzed the characteristics and steps which could have a relevant impact on the final result

Brazilian cerrado is characterized by an evident seasonality with distinct dry and wet seasons. Pyrostegia venusta is a common vine found in different physiognomies of the Cerrado. The species may present characteristics that allow its adjustment to the seasonal cycles. The phenology of vegetative and reproductive events was studied for this species in 2004 and 2005. The objective was to verify which climatic factors determine the phenological patterns observed in the species. Flowering was inversely related to mean temperatures and to the length of the day, while fruiting was inversely related to the photoperiod and directly related to the mean wind velocity. Seed dispersal was directly related to wind speed. As a consequence, flowering occurred at the end of the rainy season, close to the winter, and was prolonged until the end of the dry season. Fruiting and fruit maturation occurred during the dry period, with the seeds being dispersed at the end of this period. The seed dispersal at the end of the dry season, common to other anemochoric species of cerrado, allows a rapid germination at the beginning of the wet season, favoring the species propagation in this environment.

Some esthetical particularities of Luiz Fernando Carvalho’s micro-series reveal, in the nineteenth century Brazil, the capacity of the literary and audiovisual discourse to represent some singularities of the Brazilian social life from the past, as well as pointing to existential problems of the class representative that leads the plot, instigating reflections in the present. The treatment offered to the class struggle by the Machadian narrative and by the Rede Globo’s adaptation, just as the way in which the existential drama is expounded, disclose a kind of reception among readers/viewers which is capable of reviewing the historical past in times that ask for such a revision, even though the television series bets on the non-conventional. Machado presented the tension between representation and truth (as well as between emotion production and reflection) with the transfiguration of the tragic pathos and the mobilization of the patriarchal figure to the melodramatic bias. Although increased by the irony orchestrated by the scenic elements, in the audiovisual version such Machadian solutions would be apt to lose their strength to unmask the social subjects; on the other side, the intensification of the melodrama can make evident what Machado disguised with less obvious narrative intentions.

The Literary adaptation for television miniseries are present in the schedule grids of Brazilian television channels. We can afford that it is about a line of production of the most relevant in the two main television networks that maintain a project of teledramaturgy. The Strong presence of miniseries imposes the need to investigate the process of intersemiotic translation from the literary text to the audiovisual text on the way to reflect the esthetics of these productions in front of the constants process of tecnology mutation. In this sense the goal of this research is to analize the book adaptation O canto da sereia for television, where we identify the discursivas strategies that structure the narrativity, the themes and the figures that enable the identification with the original literary text
