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

Um estudo de novos paradigmas na realização de projetos de instalação elétrica residencial (automação)

Through awareness of new trends of consumption of the population with regard to housing, comfort, entertainment, security and sustainability, it was crafted a work that set out to study and develop the concept of home automation and how it will revolutionize the electrical installation projects and energy savings. A pre-wiring project, taking into account, basically, the installed load, is presented as a basis for comparison. The protocols for communication between intelligent devices in an automation environment, used in the work, are the X-10, LonWorks and UPnP. The home network is studied and divided into subsystems, for a better understanding, which are the lighting, audio, video and multimedia system, security, air conditioning and central vacuum system, and the idea of integrated design and system integrator is introduced, showing the change necessity in the design philosophy of electrical installations. The main means of energy savings in an automated home, such as dimerization, master off and smart meters are presented and, finally, it was concluded that there is a need to structure electrical installation projects more comprehensive with regard to home automation, in order to become more efficient and useful to users

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.

Utilização de alvos codificados do tipo ARUCO na automação do processo de calibração de câmaras

This paper presents a proposal for the automation of the camera calibration process, locating and measuring image points in coded targets with sub-pixel precision. This automatic technique helps minimize localization errors, regardless of camera orientation and image scale. To develop this technique, several types of coded targets were analyzed and the ARUCO type was chosen due to its simplicity, ability to represent up to 1024 different targets and availability of source code implemented with the OpenCV library. ARUCO targets were generated and two calibration sheets were assembled to be used for the acquisition of images for camera calibration. The developed software can locate targets in the acquired images and it automatically extracts the coordinates of the four corners with sub-pixel accuracy. Experiments were conducted with real data showing that the targets are correctly identified unless excessive noise or fragmentation occurs mainly in the outer target square. The results with the calibration of a low cost camera showed that the process works and that the measurement accuracy of the corners achieves sub-pixel precision.
