Biossegurança na clínica de radiologia odontológica

In the practice of dental radiology, although there was no production of aerosols, there is the contamination of equipment and surfaces by contact with blood and saliva. This is making necessary the adoption infection control procedures to protect patients and staff. The objective of this paper is to present the procedures of prevention during the radiographic examination and radiographic processing in the darkroom. The proposed recommendations for the area of Dental Radiology include efficient cleaning and protection of equipment and surfaces, personal protective measures and to avoid contamination of the darkroom. These recommendations are obtained by simple procedures as cover films and radiological equipment with plastic barriers.

A TV no ecossistema dos onívoros digitais

A quick setup of the digital environment that occurs in these first decades of the twentyfirst century has involved the use of electronic devices for consume content both at home, at work and on the go (ComScore, 2011). The emergence of this vast multiplatform digital landscape impels to know of individual and complementary use of these devices with ubiquitous nature or not. The widespread adoption of smartphones, tablets and other connected devices via internet makes users / consumers of these devices to feed a diet based on a constant flow of digital content across different platforms. The objective of this paper is to describe the role of television in the context of the Media Ecology which is established by the "digital omnivores" a new group of consumers whose name, according Canavilhas (2013, p.03), "is related with the platforms that consumers use to access the Internet, but also to the type of individual and multiplatform consumption they do.”

OntoSDM: an approach to improve quality on spatial data mining algorithms

The increase in new electronic devices had generated a considerable increase in obtaining spatial data information; hence these data are becoming more and more widely used. As well as for conventional data, spatial data need to be analyzed so interesting information can be retrieved from them. Therefore, data clustering techniques can be used to extract clusters of a set of spatial data. However, current approaches do not consider the implicit semantics that exist between a region and an object’s attributes. This paper presents an approach that enhances spatial data mining process, so they can use the semantic that exists within a region. A framework was developed, OntoSDM, which enables spatial data mining algorithms to communicate with ontologies in order to enhance the algorithm’s result. The experiments demonstrated a semantically improved result, generating more interesting clusters, therefore reducing manual analysis work of an expert.

Genital infections of HIV-infected women assisted by a specialized service

The present study aimed at analyzing the persistence/recurrence of genital infections and its associated factors in HIV-infected women. Fifty-eight women treated for chlamydial infection, trichomoniasis, vulvovaginal candidiasis, and/or bacterial vaginosis (BV) and who had specimens collected for cure control up to one year after treatment were studied. Diagnoses were performed by the Gram staining method for cases of BV and candidiasis and by T. vaginalis culture and qualitative PCR for C. trachomatis. Antiretroviral therapy was used by 79.3% of patients, and 62.1% showed an undetectable HIV plasma load. The most frequent infection was BV with persistence/recurrence of 52.4%, which was associated with a longer time period between treatment and cure control (P = 0.0455), postmenopausal period (P = 0.0451), and having a steady partner (P = 0.007). Persistence/recurrence of vulvovaginal candidiasis was observed in 25%, trichomoniasis in 23.1%, and chlamydial infection in 10.5%. The letter was associated with inadequate treatment of the partner (P = 0.073) among patients with low T CD4 lymphocyte counts. The majority of women in the present study showed good HIV-infection control and a vulnerable sexual behavior, which stress the importance of maintaining gynecological followup.

Desenvolvimento de conjunto membrana-eletrodos para célula a combustível de metanol direto passiva

Direct methanol fuel cells (DMFCs) without external pumps or other ancillary devices for fuel and oxidant supply are known as passive DMFCs and are potential candidates to replace lithium-ion batteries in powering portable electronic devices. This paper presents the results obtained from a membrane electrode assembly (MEA) specifically designed for passive DMFCs. Appropriated electrocatalysts were prepared and the effect of their loadings was investigated. Two types of gas diffusion layers (GDL) were also tested. The influence of the methanol concentration was analyzed in each case. The best MEA performance presented a maximum power density of 11.94 mW cm^-2.

Growth and Characterization of Silicon Carbide Thin Films Using a Nontraditional Hollow Cathode Sputtering Technique

Silicon carbide (SiC) is considered a suitable candidate for high-power, high-frequency devices due to its wide bandgap, high breakdown field, and high electron mobility. It also has the unique ability to synthesize graphene on its surface by subliming Si during an annealing stage. The deposition of SiC is most often carried out using chemical vapor deposition (CVD) techniques, but little research has been explored with respect to the sputtering of SiC. Investigations of the thin film depositions of SiC from pulse sputtering a hollow cathode SiC target are presented. Although there are many different polytypes of SiC, techniques are discussed that were used to identify the film polytype on both 4H-SiC substrates and Si substrates. Results are presented about the ability to incorporate Ge into the growing SiC films for the purpose of creating a possible heterojunction device with pure SiC. Efforts to synthesize graphene on these films are introduced and reasons for the inability to create it are discussed. Analysis mainly includes crystallographic and morphological studies about the deposited films and their quality using x-ray diffraction (XRD), reflection high energy electron diffraction (RHEED), transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM), Auger electron spectroscopy (AES) and Raman spectroscopy. Optical and electrical properties are also discussed via ellipsometric modeling and resistivity measurements. The general interpretation of these analytical experiments indicates that the films are not single crystal. However, the majority of the films, which proved to be the 3C-SiC polytype, were grown in a highly ordered and highly textured manner on both (111) and (110) Si substrates.

DEVELOPMENT OF AN EXPERIMENTAL MODEL OF INFECTED BONE VOID IN THE ULNA OF RABBITS

Objective: Develop a model that allowed the study of bone regeneration in infection conditions. Method: A 15 mm defect was surgically created in the rabbit ulna and inoculated with 5x10(8) colony-forming units (CFU) of S. aureus. Surgical debridement was performed two weeks after and systemic gentamicin was administered for four weeks. Animals were followed up to 12 weeks to evaluate infection control and bone regeneration. Result: Bone regeneration was inferior to 25% of the defect in radiological and histological analysis. Conclusion: Infected bone defect of 15 mm in the rabbit ulna was unable to achieve full regeneration without further treatment. Level of Evidence V, Experimental Study.
