Anatomia foliar e análise de EDX de Costus spiralis (Jacq.) Roscoe de ambiente impactado e não impactado do litoral de São Paulo.

Several plants show morphological changes when exposed to environmental stress. We aimed to analyze comparative anatomy and EDX (energy dispersive x-ray detector) of Costus spiralis (Jacq.) Roscoe leaves from Jureia-Itatins Ecological Station (Peruibe, Sao Paulo), a preserved area, and Mogi River Valley (Cubatao, Sao Paulo) an affected area by pollution from the industrial complex of Cubatao. There were some significant differences in the leaves from the affected area, where they had a smaller abaxial hypoderm, larger size of adaxial hypoderm and larger central vascular core. There were damages in epicuticular wax deposition. The EDX analyses presented only differences in calcium and potassium concentration and presence of manganese in Cubatdo samples. Those leaves presented crystal deposition in the vascular core, probably because of the phosphogypsum residues from fertilizer industries.

A mediação da informação nos arquivos permanentes: serviços de referência arquivística no ambiente digital

Information Science has for its object of study the general properties of information and analysis of their construction, communication and use processes. Organic information, one of the information types, is the one recorded in the archives, which can be split into two distinct groups based on users: current and permanent, used by administrators, historians/citizens, respectively. After defining the information behavior of each group, the articles directs the discussion to the mediation of information in the permanent archives. The interaction between user and information professionals through references services aiming the user needs is presented. In addition, the standards of archival description and the research instruments as tools to reference service are discussed. Moreover, it argues the importance of information technologies and the new possibilities for the promotion of organic information in permanent archives, especially concerning the information architecture of websites and the conversion of the DTD standards of archival descriptions.

Estudo etnobiológico da interação dos pescadores de cerco-fixo com as tartarugas marinhas da região de Cananéia, litoral sul de São Paulo

Marine turtles are reptiles that occur on the Brazilian coast and can travel very large distances between feeding and nesting grounds. Five species found in Brazil are threatened. The consumption of turtle meat and eggs is an ancient habit in many coastal communities around the world. The main causes that threaten these species are the increase in fishing and the drastic changes in the environment. The presence of turtles near the beaches and their accidental capture were reported by fishermen in the region of Cananéia, where this work was developed. This study was also made based in interviews of fishermen that living in the area and the follow up of their fishing activities. This methodology made possible to identify the turtles in the area, the behavior of the fishermen with these animals and the relation between non-commercial fishing and turtles. The fishing traps area has a direct relation with the capture of turtles. The higher incidence of turtle capture is usually next to islands, rocky coasts, low lands and bay entrances, which are areas where the most common species of the region (Chelonia mydas) normally look for food. The fishermen opinions about the critical situation of these species and their conservation has also been studied. Several programs in Environmental Education for the communities of the region have been recommended

Diagnóstico populacional e comportamental de saguis-de-tufo-preto (Callithrix penicillata) em ambiente peri-urbano

The black-tufted-marmoset (Callithrix penicillata), abundant in the southeastern state of São Paulo, is an exotic and invasive species . The present study aimed to study the behavior and make monitoring a population black-tufted-marmoset in man-made environment. The observations were made following the method of scan sampling, which consists of continuous observations with a duration of three minutes with a fifteen-minute intervals between one record and another. The individuals are monitored at two locations on campus, where two groups were identified (with a mean of 3.50 ± 2.06 individuals) totaling 291 hours and 30 minutes of observation. Were determined tree layers used, and observed that the group of EC preferably utilizes the highest stratum, while the group of LCF uses the middle and lower strata. Types of vocalization, such as calling, interaction and alert and frequency and percentage of these were also observed. The food items consumed by the groups that are similar in the two study sites, mostly sap and leaves were diagnosed. From observations of behavioral patterns was possible to construct an ethogram of the species ' Luiz de Queiroz ' campus, comprising the behaviors of vocalization, locomotion, foraging, game, among others. The results may be useful for development of management techniques and for subsequent studies

Redes de interação entre dispersores de sementes e Euterpe edulis (Arecaceae) em um grandiente de defaunação

As alterações antropogênicas ao ambiente vêm afetando muitos componentes dos ecossistemas naturais, produzindo frequentemente um padrão não aleatório de extinções, associado a características espécie-específicas. Por sua vez, a extinção local de espécies muitas vezes se traduz na perda de interações. Dessa forma, a perda de frugívoros, pode acarretar mudanças na estrutura das interações mutualísticas, com consequências futuras para espécies de plantas que dependem destes para a dispersão de suas sementes. Uma das espécies potencialmente afetada pela perda de frugívoros, principalmente os de grande porte, é o palmito juçara (Euterpe edulis). Exploramos aqui então se a extinção local de aves frugívoras se dá de uma maneira não aleatória e investigamos as consequências dessas extinções para o processo de remoção e dispersão de sementes de E. edulis. Observamos um padrão aninhado e modular na comunidade de dispersores de sementes de palmito juçara, indicando que as extinções ocorrem de forma não aleatória. Utilizando um índice de diversidade taxonômica observamos também que certos clados taxonômicos são mais propensos à extinção local, assim como previmos no início. Assim, fica então evidente que a extinção local dos frugívoros de E. edulis ocorre de maneira não aleatória, havendo estreita relação taxonômica entre estas espécies primariamente extintas, sendo os grande dispersores os mais afetados. Em áreas não defaunadas, apesar de observarmos uma baixa taxa de visitação, há uma alta taxa de consumo, sendo os grandes e médios dispersores importantes responsáveis pela remoção de sementes nestes locais. Em contrapartida, consequência da própria perda dos grandes frugívoros, áreas defaunadas demostraram baixa visitação de frugívoros aos frutos de E. edulis e baixa taxa de consumo destes, sendo os principais dispersores...

O efeito da autocorrelação no desempenho dos gráficos de X e R e dos gráficos de X e S²

Control charts are very important tools in statistical quality control of industrial processes and its use started last century. Since its development, the charts have always been attributed to independent processes, i.e. without any correlation between samples. But nowadays, with the high level of automation in the industrial environment, it is noticeable the autocorrelation factor between samples. The main Xcharts used in monitoring quality characteristics represented by continuous variables are the mean (X ), amplitude (R) and variance (S²). Therefore, this work aims to analyze the performance of X and R charts and in of X and S² charts with different sample sizes (4 and 5) for monitoring autocorrelated processes. Through computer simulations using the Fortran software and the use of mathematical expressions was possible to obtain data and performance analysis of the detection power charts for independent observations and for autocorrelated observations according to the model AR (1). The results show that the effect of autocorrelation reduces the ability of monitoring the control charts and that, the greater this effect, the slower the chart becomes in misfits signaling

Preparação e caracterização de filmes finos ferroelétricos nanoestruturados do tipo Pb1-x(Ca,Ba)xTiO3

O rápido crescimento do mercado de dispositivos eletrônicos portáteis, com aplicações em diferentes áreas (telecomunicações, medicina, engenharia), criou uma grande demanda por fontes de potência compactas leves e, sobretudo, de baixo custo. Essa demanda levou ao desenvolvimento de tecnologia de filmes finos nanoestruturados para a obtenção de componentes eletroeletrônicos, por exemplo, memórias de computador. Estes dispositivos são empregados em “notebooks”, circuitos integrados, telefones celulares. O estudo de cristalização de filmes finos ferroelétricos nanoestruturados será feito através da cristalização induzida por rotas convencionais tal como cristalização em forno mufla. A modulação entre os diferentes cátions (Pb, Ca e Ba) para formar o sistema Pb1-x(Ca,Ba)xTiO3 serão analisadas, visando obter filmes com propriedades compatíveis para uso em memórias ferroelétricas. Para isso, os filmes finos serão depositados em substratos adequados controlando-se a homogeneidade química, a microestrutura e a interação filme-substrato

Basquetebol X temas transversais: a produção de material didático audiovisual para a Educação Física escolar

This study aimed, first, produce a kind of educational materials in audiovisual format, to the Physical Education, addressing the Transversal Themes in view of the basketball. The themes chosen were Cultural Plurality, addressing the basketball in a wheelchair, and Labor and Consumer Affairs, addressing the marketing and exploitation of labor force that the company is Nike. There is no doubt the importance of media production in contemporary society, as one of its main languages, but of little relevance in the school environment, especially in the area of Physical Education. In a second phase aimed at evaluating the feasibility of this material both as a teaching strategy, such as content of learning lessons. The evaluation was made through a discussion in the form of focus groups with 10 students from 9 th grade of elementary school. The results showed that despite an initial rejection of the material as a teaching strategy because of the history that Physical Education has for several years, students were open to new ways of learning. Since the results on the material, such as learning content, showed that the videos were able to address and the Transversal Themes and meet the need for procedural content with the proposed activities. With this, we realize that students are willing to discuss matters that are not always addressed, but now, with the creation of national curriculum standards should be reflected in the classroom
