Marine debris ingestion by sea turtles (Testudines) on the Brazilian coast: an underestimated threat?

Assessment of marine debris ingestion by sea turtles is important, especially to ensure their survival. From January to December 2011, 23 specimens of five species of sea turtleswere found dead or dying after being rehabilitated, along the coast of the municipality of Rio de Janeiro, Brazil. To detect the presence of marine debris in the digestive tract of these turtles, we conducted a postmortemexamination from the esophagus until the distal portion of the large intestine for each specimen. Of the total number of turtles, 39% had ingested marine debris such as soft plastic, hard plastic, metal, polyethylene terephthalate (PET) bottle caps, human hair, tampons, and latex condoms. Five of the seven sea turtles species are found along the Brazilian coast, where they feed and breed. A large number of animals are exposed to various kinds of threats, including debris ingestion

Fatores que influenciam a escolha de comida saudável nos estudantes universitários

Healthy foods should be available to anyone, especially young adults at educational institutions. University students can suffer a lack of preoccupation with their health and consequently also present unhealthy food choices, due to the adaptation of a new environment, study stress, lack of proper time management, and busy class schedules. This study consisted of two cross-sectional observational analyzes, in which students were randomly recruited from the university, and data was obtained through the Computer-aided web interviewing survey method, through a web-based questionnaire. The sample included 584 participants, 297 from 2018 and 287 from 2019. The preference and choice for a healthy snack bar in university facilities seem to be conditioned mainly by the price of meals, as most students mentioned this as the main condition of their choice, both in 2018 and 2019. In this sense, most respondents report that only "sometimes" would they be willing to pay more than usual or travel a longer distance, to dine in a healthier snack bar. We conclude that the factor that most influences the choice of healthy food is the price, but there is a higher demand and consumption trend for healthy food in young college students.Alimentos saudáveis deveriam estar disponíveis para qualquer pessoa, especialmente para jovens adultos nas suas instituições de ensino. Devido à adaptação a um novo ambiente, stress provocado pelo estudo, falta de gestão adequada do tempo e horários ocupados pelas aulas, os estudantes universitários podem sofrer de falta de preocupação com a sua saúde e, consequentemente, também apresentar escolhas alimentares pouco saudáveis. Este estudo consistiu em duas análises observacionais transversais. Os estudantes foram recrutados aleatoriamente na universidade, e os dados foram obtidos através do método de pesquisa Computer-aided web interviewing, através de um questionário enviado pela web. A amostra final incluiu 584 participantes, sendo que 297 são procedentes da análise de 2018 e 287 de 2019. A preferência e escolha por um bar mais saudável nas instalações universitárias, parece ser condicionada, sobretudo, pelo preço das refeições, já que a maioria dos estudantes referiu esta como a principal condicionante da sua escolha, tanto em 2018, como em 2019. Neste sentido, a maioria dos inquiridos refere que só “às vezes” estaria disposto a pagar mais do que o habitual, ou percorrer uma maior distância, para efetuar as suas refeições num bar saudável. Concluímos que o fator que mais influencia a escolha de comida saudável é o preço, contudo parece existir uma maior procura, preocupação e tendência de consumo por comida saudável nos jovens universitários.info:eu-repo/semantics/publishedVersio

Prevalence of major apical foramen mismatching the root apex in root canals of human permanent teeth

The periapical radiograph is used to determine the working length in endodontic treatment. However, this radiograph does not define the position of the major apical foramen. Objective: This ex vivo laboratorial study aims to determine the prevalence of the major apical foramen mismatching the root apex in human permanent teeth, because when present, this mismatch makes the radiographic method inaccurate for determining the working length. Material and methods: This study used 400 human permanent teeth: 100 incisors, 100 canines, 100 premolars, and 100 molars, totalizing 634 canals (Ethics Committee, Federal University of Ceará #263/10). The access and negotiation of the root canals were performed with K-type files #10 and #15 until the tip of the instrument were visible at the root foramen through 5-fold magnifying glass. Periapical radiographs were performed on bucco-lingual incidence for single-rooted teeth; the incidence angle was changed for multi-rooted teeth. The films were processed and then analyzed by three calibrated examiners (Kappa 80%). Descriptive statistics and chi-square test were used for analyzing of the results. Results: The prevalence of major apical foramens mismatching the root apex was 19.72% of the canals studied. The incisors showed the lowest prevalence (9%, p<0.05) while the highest prevalence was seen in canine teeth (28%). Conclusion: According to the methodology applied, the prevalence of major apical foramens mismatching the root apex foramens make necessary an adjunct method for determining the working length, because it alone was not capable of determining the foramen position.The periapical radiograph is used to determine the working length in endodontic treatment.

Management of Six Root Canals in Mandibular First Molar

Success in root canal treatment is achieved after thorough cleaning, shaping, and obturation of the root canal system. This clinical case describes conventional root canal treatment of an unusual mandibular first molar with six root canals. The prognosis for endodontic treatment in teeth with abnormal morphology is unfavorable if the clinician fails to recognize extra root canals

Finding Software Vulnerabilities in Open-Source C Projects via Bounded Model Checking

Computer-based systems have solved several domain problems, including industrial, military, education, and wearable. Nevertheless, such arrangements need high-quality software to guarantee security and safety as both are mandatory for modern software products. We advocate that bounded model-checking techniques can efficiently detect vulnerabilities in general software systems. However, such an approach struggles to scale up and verify extensive code bases. Consequently, we have developed and evaluated a methodology to verify large software systems using a state-of-the-art bounded model checker. In particular, we pre-process input source-code files and guide the respective model checker to explore them systematically. Moreover, the proposed scheme includes a function-wise prioritization strategy, which readily provides results for code entities according to a scale of importance. Experimental results using a real implementation of the proposed methodology show that it can efficiently verify large software systems. Besides, it presented low peak memory allocation when executed. We have evaluated our approach by verifying twelve popular open-source C projects, where we have found real software vulnerabilities that their developers confirmed.Comment: 27 pages, submitted to STTT journa

a pilot study in mice

Pneumocystis pneumonia (PcP) is a major cause of mortality and morbidity in immunocompromised patients. There are limited alternative therapeutic choices to trimethoprim-sulfamethoxazole (TMP-SMX) which is the standard first line therapy/prophylaxis for PcP. The efficacy of low doses of caspofungin and caspofungin in association with TMP-SMX standard-prophylactic dose was evaluated in an experimental model of Pneumocystis. Susceptibility of Pneumocystis spp. to low doses of caspofungin and caspofungin/TMP-SMX was evaluated in Balb/c immunosuppressed mice, infected intranasally with P. murina. Caspofungin was administered once daily at 0.1 mg/kg, 0.05 mg/kg, and 0.001 mg/kg and TMP-SMX was administered by oral gavage (12.25 mg/62.5 mg/day), for 21 days. Efficacy was calculated based on the reduction in organism burden determined through quantitative fluorescent-based real-time PCR (qPCR). Serum β-1,3-D-glucan was measured as an additional marker of infection. The present data showed that caspofungin demonstrated anti-Pneumomocystis effect. However, the doses administrated were too low to achieve Pneumocystis eradication, which suggests that echinocandin treatment should not be administrated as mono-therapy. After 21 days of treatment, P. murina was not detected in the lungs of mice with either TMP-SMX or caspofungin/TMP-SMX. The results showed that, even at the lowest concentrations tested, the efficacy of caspofungin in association with TMP-SMX was higher than the efficacy of either drug used alone. The administration of caspofungin/TMP-SMX was at least 1.4 times more effective against P. murina infection than TMP-SMX used alone. The most promising result was achieved with the combination of caspofungin 0.05 mg/kg/day with TMP-SMX 12.5 mg–62.5 mg/day, which reduced the parasite burden to undetectable levels immediately at the 14th day of treatment, showing a highly marked anti-Pneumomocystis effect. These data suggest that the administration of low doses of caspofungin in combination with low doses of TMP-SMX may provide an improved treatment protocol for Pneumocystis infection clearance.publishersversionpublishe

Legitimacy accounts in the debate about the reform of Brazilian courts of accounts

O objetivo desta pesquisa foi investigar o processo político-cultural relacionado ao debate em torno da reforma dos Tribunais de Contas brasileiros (TCs), organizações de aplicação da lei responsáveis pelo controle de recursos públicos. A pesquisa centrou-se em analisar como legitimacy accounts conduzidos por diferentes categorias de atores se manifestaram no debate acerca da reforma dos TCs brasileiros no período de 2000 a 2017. Foram coletados dados de fontes documentais como discursos parlamentares, audiências públicas, debates e notícias. Também foram realizadas entrevistas com representantes de diversas categorias de atores, incluindo corporações profissionais, mídia, academia e sociedade civil organizada. Por meio da análise do processo de mobilização e dos argumentos centrais que apelaram para a legitimidade da reforma (legitimacy accounts), os resultados apontaram para: (a) a centralidade das corporações profissionais, tanto na mediação e tradução do debate, quanto no desenho de estratégias de intervenção no campo organizacional, e; (b) a identificação de aspectos organizacionais, relacionais, processuais, jurisdicionais e responsivos ligados à multidimensionalidade da legitimidade dos TCs. Os resultados contribuem para as áreas de estudos organizacionais, de administração pública e de administração da Justiça.The objective of this research was to investigate the political-cultural process related to the debate on the reform of Brazilian Courts of Accounts (CAs), law enforcement organizations responsible for controlling public resources. The research focused on analyzing how legitimacy accounts conducted by different categories of actors manifested themselves in the debate about the reform of Brazilian CAs from 2000 to 2017. We collected data from documentary sources, such as parliamentary speeches, public hearings debates, and news. Interviews were also conducted with representatives of the various categories of actors, including professional corporations, media, academia, judiciary, and organized civil society. Through the analysis of the mobilization process and the central arguments that called for the legitimacy of reform (legitimacy accounts), the results pointed to: (a) the centrality of professional corporations, both in the mediation and translation of the debate, and in the design of intervention strategies in the organizational field, and; (b) the identification of organizational, relational, procedural, jurisdictional and responsive aspects related to the multidimensional legitimacy of CAs. The results contribute to the areas of organizational studies, public administration and administration of justice

Statistical Audit via Gaussian Mixture Models in Business Intelligence Systems

A Business Intelligence (BI) System employs tools from several areas of knowledge for the collection, integration and analysis of data to improve business decision making. The Brazilian Ministry of Planning, Budget and Management (MP) uses a BI System designed with the University of Bras´ılia to ascertain irregularities on the payroll of the Brazilian federal government, performing audit trails on selected items and fields of the payroll database. This current auditing approach is entirely deterministic, since the audit trails look for previously known signatures of irregularities which are composed by means of an ontological method used to represent auditors concept maps. In this work, we propose to incorporate a statistical filter in this existing BI system in order to increase its performance in terms of processing speed and overall system responsiveness. The proposed statistical filter is based on a generative Gaussian Mixture Model (GMM) whose goal is to provide a complete stochastic model of the process, specially the latent probability density function of the generative mixture, and use that model to filter the most probable payrolls. Inserting this statistical filter as a pre-processing stage preceding the deterministic auditing showed to be effective in reducing the amount of data to be analyzed by the audit trails, despite the penalty fee intrinsically associated with stochastic models due to the false negative outcomes that are not further processed. In our approach, gains obtained with the proposed pre-processing stage overcome impacts from false negative outcomes
