NECOS Project: Towards Lightweight Slicing of Cloud Federated Infrastructures

The Novel Enablers for Cloud Slicing (NECOS) project addresses the limitations of current cloud computing infrastructures to respond to the demand for new services, as presented in two use-cases, that will drive the whole execution of the project. The first use-case is focused on Telco service provider and is oriented towards the adoption of cloud computing in their large networks. The second use-case is targeting the use of edge clouds to support devices with low computation and storage capacity. The envisaged solution is based on a new concept, the Lightweight Slice Defined Cloud (LSDC), as an approach that extends the virtualization to all the resources in the involved networks and data centers and provides uniform management with a high-level of orchestration. In this position paper, we discuss the motivation, objectives, architecture, research challenges (and how to overcome them) and initial efforts for the NECOS project

CLINICAL SIGNS AND SYMPTOMS OF SEXUALLY TRANSMITTED INFECTIONS COMMUNICATED IN LIBRAS

Abstract OBJECTIVE To validate a video containing image representations of clinical signs and symptoms of sexually transmitted infections expressed in Libras. METHOD Methodology development study conducted in an audio communication school. Thirty-six deaf people were selected. A video containing image representations of clinical signs and symptoms of sexually transmitted infections expressed in Libras was produced. Semantic validation was performed by deaf students and content validation by three judges who are Libras experts. The validation results were subjected to the Content Validity Index, where an index score > 0.80/80% was considered as agreement among judges. RESULTS Seven signs and symptoms related to sexually transmitted infections were validated and obtained satisfactory Content Validity Indexes, most of them with 100% representativeness and agreement. CONCLUSION The validation process made the expressions of signs and symptoms related to sexually transmitted infections represented in Libras valid for establishing effective communication in the area of the study, turning it into a care tool that facilitates and standardizes communication with deaf people through Libras

EFFICACY OF DENTURE CLEANSERS ON CANDIDA SPP. BIOFILM FORMED ON POLYAMIDE AND POLYMETHYL METHACRYLATE RESINS

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Statement of problem. Although new materials have emerged as options to fabricate removable dental prostheses, the development of Candida biofilms on these materials and the effectiveness of methods to control these pathogenic biofilms are poorly understood. Purpose. The purpose of this study was to evaluate the efficacy of denture cleansers on Candida single- and dual-species biofilms formed on polyamide resin. Material and methods. Polymethyl methacrylate (PMMA) resin (Acron MC) and polyamide resin (Flexite M.P.) specimens (n=116) were prepared, and their surface roughness was standardized (0.34 +/- 0.02 mu m). Surface free energy (SFE) was measured for some specimens (n=20 per resin), while the remainder were randomly divided by lottery into 24 groups (n=8) for biofilm assay. C. albicans and/or C. glabrata biofilm was formed for 72 hours, and then specimens were treated with an enzymatic cleanser solution (Polident 3 Minutes), a cleanser solution (Corega Tabs), or 0.5% sodium hypochlorite (NaOCl) solution. Water served as the negative control. Remaining adherent microorganisms were removed from the treated specimens by ultrasonic waves, and colony-forming units (CFU) of each microorganism were calculated. SEE data were analyzed by 1-way ANOVA, and Candida species data were analyzed by 3-way ANOVA followed by the Tukey-Kramer test (P=.05). Results. All tested biofilms displayed significantly higher growth on polyamide resin (P<.001), which presented the lowest SEE. Denture cleansers significantly decreased Candida levels; however, the 0.5% NaOCl solution was the only effective cleanser. C. glabrata revealed significantly higher CFU counts under all experimental conditions (P<.001). Conclusions. The highest Candida spp. biofilm growth was shown to occur on polyamide resin when compared with PMMA. Denture cleansers were able to remove Candida spp. biofilm formed on both denture base resins.
