Caracterização morfológica e fenotípica de leveduras do gênero Cryptococcus com ênfase na pesquisa de Cryptococcus neoormans isoladas de amostras de água de mar e areia de três ambientes costeiros do estado de São Paulo: Canal de São Sebastião, Baixada Santista e Ubatuba

The yeast Cryptococcus neoformans is the etiologic agent of cryptococcosis, an infectious cosmopolitan disease that affects humans. Although rare, this disease is potentially fatal, especially for immunocompromised hosts. This pathogen is frequently isolated from excrements of pigeons and parrots, with many environmental sources such as birds, pigeon droppings, eucalyptus leaves, decaying trees, towers, churches and places of storage of grain (the port area). The isolation of this microorganism has been obtained also from the aquatic environment. The identification of environmental sources is needed to protect human health, especially susceptible populations such as immunocompromised. Therefore, this study investigated the presence of Cryptococcus neoformans in yeast isolates obtained from samples of sea water and sand from three regions of São Paulo: São Sebastião Channel, Santos and Ubatuba. Isolates were analyzed according to micro-and macroscopic characteristics and biochemical tests: microculture, urease, ink nankin, auxanograma, zymogram and phenol. We analyzed 199 isolates, 175 of which had features suggestive for Cryptococcus spp. in microculture. All these 175 isolates were sown in the Christensen urea middle to verify the production of urease and submitted to the technique nankin ink to visualize the capsule. Of these, only 24 were selected for the next test that was the auxanograma (assimilation of carbohydrate and nitrogen). Of the 24, 10 were tested in zymograms (fermented sugar), from which 5 were selected for the phenoloxidase test in medium containing dopamine. None of the 5 isolates tested had black or brown color characteristic of Cryptococcus neoformans. According to these tests, we arrived at 5 isolates identified to the genus Cryptococcus, but not the neoformans specie

Estudo da concentração de material particulado em ambientes internos e externos de bibliotecas

Our twenty-first century society and the rhythm of life and work we have to face in our daily routine compel us to spend most of our lifetime in closed environments, in our houses, educational institutions, hospitals, airports, amongst as many others. The study of the air quality in internal environments (IAQ) is very important for monitoring people’s health effects and their environmental comfort in these locations. One essential parameter to analyze this measure is to evaluate the concentration of dispersed particulates in the air, specially focusing on those thinner particles (below the diameter of 2,5 μm), they can pose serious risks for human being because they can remain in the lungs, penetrate through the pores of our skin, amongst other harmful effects on human’s health. In this work the air quality inside the public library Profª Josina Vasques Ferrari and at Unesp public state library was evaluated, both located in Itapeva, as well as a third one, inside the Communitarian Library of the Federal University in Carlos (UFSCar) from march to may in 2012. In those environments it was analyzed if the concentration of particulates pose any real treat to the users. The equipment used for particle sampling in real time was DataRam 4 (Model DR 4000). The results given for those concentrations of particulates in both internal and external environments revealed figures within the safe standard established by the WHO (World Health Organization), from 25 to μg/m³, the only exception occurred on the fifth floor of the UFSCar library, where the average for concentration stayed at 25,30 of μg/m³

Relações públicas e serviços virtuais: a comunicação entre as corporações da internet e o cibernauta

The objective of this study is to adress the action possibilities of the Public Relations professional in management of communication between the virtual services companies and their customers – the cybernauts. For this purpose, a bibliographical research was made about the cyberspace, Internet environment, as well as the cyberculture and the on-line consumer public. It was also studied the possible areas of Public Relations's action, their work tools and means of communication with the customer, in order to verify the specificities of communication mediated by new technologies. Based on these concepts, it was possible to propose an action of this professional in the organizations called dotcom, in order to contribute to the management of the communication flow between companies and this “invisible” public, which relates virtually to the organization, establishing different modes of interaction in relation to tradicional customers, requiring different strategies of relashionsip

O aprimoramento de um software de estúdio virtual por meio de técnicas de matting digital e registro de objetos virtuais

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented

Leitura em Ambientes Cíbridos: a cosmo(a)gonia geométrica de Patrick Burgaud

Contemporary culture is showing us, with growing evidence, that fields of knowledge and spheres of action interpenetrate strongly, forcing us to change behavior in order to connive with the productive and creative new ways. Our scope is to consider the cybrid environment in which we situate the reader in his relations with the poetic productions created in the digital world, from the perspective of a contemporary context of reading done through interfaces and also by a reading of a poem by Patrick Burgaud.

Formação Reflexiva do Professor em Contextos Virtuais: A Experiência do Projeto Teletandem Brasil

This article chiefly aims at discussing issues concerning reflective teacher education for and in virtual environments for language learning. Given the need for research on reflective practice in new virtual environments, we present the experience of pedagogical supervision through mediation in the virtual context for collaborative learning in teletandem. Some research results in this context, such as in Salomão (2008), Kfouri-Kaneoya (2008), Cândido (2010) and Silva (2010), show how favorable and conducive to the development of reflective pre-service teacher education it seems to be, as it emphasizes the co-construction of knowledge in a dynamic relationship between theory and practice.

Laços de família e segredos (sexuais) compartilhados: narrativa de história de vida de uma jovem dissidente em uma família homofóbica

This paper presents a non-heterosexual young lady s Narrative Life History. By presenting it, we aim to understanding how desire, (in)visibility and the processes of exclusion are articulated in relation to the experience of homoeroticism, especially within the family. By this, we are able to point out some homophobic aspects, modes of how the device of closet operates and how some expectations and demands exert pressures over a non-heterosexual member in the family. In this case study, the way her family lived her sexuality depended on a strong family ties, such as: the secret about sexuality. Such secret, according to our hypothesis, was produced and preserved by homophobia which served as the major aspect on the construction of gender and (dis)unity of the family. This work is part of a in progress doctoral thesis, sponsored by FAPESP Fundação para o Amparo à Pesquisa no Estado de São Paulo.
