Background: Obesity has reached epidemic patterns and constitutes a serious public health problem due to comorbidities and the impact on life quality of affected individuals. Bariatric surgery appears as one of the most recommended treatments;however much has been known about the effects of this intervention on the functional performance of the organism as a whole. Objective: To characterize the oral health of adults submitted to bariatric surgery, before and after the intervention, with emphasis on the performance of masticatory function. Methods: A prospective observational cohort study conducted in a public reference service to the treatment of obesity in the city of Recife, State of Pernambuco. The data were obtained during the first half of 2011, through interview, intraoral physical examination and evaluation of masticatory function. Statistical treatment adopted was a CI of 95% and the chi-square test. The collection was conducted in three stages, with initial assessment in the preoperative and follow-up at 60 and 180 days. Results: The sample consisted of 20 volunteers, aged between 23 and 58 years and mean BMI of 43.2 ± 2.8. When compared the pre-operative to the control periods, there were significant differences for variables with decreased tendency towards spontaneous gingival bleeding and increased tooth hypersensitivity and tooth mobility (p < 0.05). Regarding the masticatory function, we found significant differences for most of the variables investigated, except in the coordination of movements and breathing during this function. Conclusion: The performance of masticatory function shows differences in pre- and postoperative periods for bariatric surgery.

Oral health status and performance of oral functions in children and adolescents in the treatment for overweight or obesity

The objective of this study was to evaluate the performance of oral functions and oral conditions in children and adolescents with overweight or obesity, investigating possible associations with treatment for weight reduction. Developing a cross-sectional research and quantitative approach with inductive and descriptive and critical analysis of data, such as from a range of 95%, the universe was represented by children and adolescents who were overweight or obese, in both sexes, treated at reference centers for the treatment of obesity by the National Health System, in Campina Grande, Paraíba, 2010-2012. As the control group considered subjects of the same age, in the process of screening for attention in the places listed, but without the condition of overweight or obese, the research was started after the approval by the Ethics Resarch Committee of the UEPB under the protocol number 0513.***.133.000-09. As instruments for data collection were used in the questionnaire and clinical examination, of the 70 surveyed, most were female, ranging in age from 3 to 17 years, overweight, without comorbidities and carriers of deleterious oral habits;especially the nail biting, significantly associated with female sex p < 0.05. Consistency was the preferred food paste and chewing quickly, unilaterally, without discomfort or gagging constant. There was a significant difference between the values of the DMFT index, the presence of visible biofilm and the frequency of halitosis, for groups with overweight or obesity, with association between time of treatment and medications.

Assessment of alterability of basalt used for riprap by petrographic examination

引用

Journal of Rock Mechanics and Geotechnical Engineering 2019年第1期11卷 208-213页

作者： maria Heloisa barros de Oliveira Frascá MHB Geological Services

All engineering projects consist of several steps, and one of the main tasks is to identify and characterize the most important features of rock types that will be excavated, crushed, or mined for any particular usage purpose, from a single residential building to major works of infrastructure. Laboratory investigation on engineering geology is thus conducted in order to determine the most relevant rock properties when designing structures such as mining shafts, tunnels, buildings, or reservoir dams to be built in sites associated with rocks. A wide range of laboratory tests is available, making the correct choice of test methods greatly relevant to determine the key property for the planned use of the rock. This paper is an illustrative case of laboratory testing of basaltic rocks to be used as riprap in a reservoir dam. It shows the important role of the petrographic study carried out to analyze the distribution pattern of smectite clay minerals. Test results are explained for the assessment of rock alterability, an essential aspect for the selection of the most suitable basalt variety for the envisaged conditions of use.

Clique Approach for Networks:Applications for Coauthorship Networks

Coauthorship networks consist of links among groups of mutually connected authors that form a clique. Classical approaches using Social Network Analysis indices do not account for this characteristic. We propose two new cohesion indices based on a clique approach, and we redefine the network density using an index of variance of density. We have applied these indices to two coauthorship networks, one comprising researchers that published in Mathematics Education journals and the other comprising researchers from a Computational Modeling Graduate Program. A contextualized and comparative analysis was performed to show the applicability and potential of the indices for analyzing social networks data.
