title: Removable partial or complete dentures exposed to beverages and mouthwashes: evaluation of microhardness and roughness

description: AbstractPurposeTo evaluate microhardness and roughness of denture base polymethylmethacrylate resinn exposed to acid beverages and mouthwashes.Material and methodRectangular samples (n=80) were prepared from poly (methyl methacrylate) (PMMA). They were divided into 8 groups and had the initial microhardness and Knoop roughness measured. Samples of each group were immersed for 10 min into a test solution (coffee, lemon juice, chlorhexidine gluconate, red wine, cola-based soft drink, vinegar or antiseptic with and without alcohol) and after stored in artificial saliva for 23 h and 50 min, completing a period of 24 h. This procedure was performed for 14 consecutive days and after this period the microhardness and surface roughness measurements were made again. Data were statistically analyzed using ANOVA non parametric, Kruskal-Walis and the Dunn´s test for microhardness and the t-Student and ANOVA for roughness.ResultFor microhardness there were found statistically significant differences among the chlorhexidine gluconate solution, antiseptic without alcohol and cola-based soft drink. For roughness was observed that the mean values between the initial period and after immersion in the test products differed statistically in all groups, without difference among groups.ConclusionThe microhardness of poly(methyl methacrylate) was affected by continue exposition to chlorhexidine gluconate, antiseptic without alcohol and cola-based soft drink. The roughness of poly(methyl methacrylate) is negatively influenced by the exposure to all tested products. It may be concluded that both, microhardness and roughness, were affected by the treatments.

title: Apatite multi-generations in the Três Estradas Carbonatite, Southern Brazil: physical and chemistry meaning and implications to phosphate ore quality

description: Abstract Carbonatites were recently discovered in Southern Brazil, which increased the interest to evaluate the economic potential of these uncommon rocks, especially the Três Estradas Carbonatite. Carbonates are the dominant minerals of fresh rock followed by apatite, but the weathering process makes apatite abundant. We focused on apatite from the carbonatite using conventional petrography and electronic microscopy associated with microprobe, micro-Raman and Fourier-transform infrared spectroscopy. Results demonstrate the existence of four types. The primary type is associated with the rock crystallization and the subsequent three others are associated with weathering processes. The alteration mechanism was favorable for initial carbonate leaching and subsequent increase of phosphate with late precipitation of three new apatite generations. The deduced model involves long exposure during polycyclic climate changes, intercalating periods of warm dry with humid climate. The apatite types differ chemically and morphologically and have distinctive characteristics that are suitable to be used to differentiate them. These properties should be considered in future planes of industrial processes to transform apatite into single superphosphate, a basic input for fertilizer production.

title: GROUND REACTION FORCE ANALYSIS OF THE YOUNG AND ELDERLY GAIT ON THE INFLUENCE OF THE OVERWEIGHT SIMULATION

description: ABSTRACT The aim of this study was to evaluate the ground reaction forces (FRS) in young and old individuals under the influence of simulated overweightin differents gait speeds. Method: 30 participants, 15 young (YNG; 22±3.7 years) and 15 older adults (OA; 69.8±6.4 years) walked on a walkway with and without an additional load. The simulation of overweight occurred through the addition of load in a variable load vest until reaching the body mass index (BMI) of overweight (BMI YNG 25kg/m²; OA 27kg/m²). FRS were measured using an force platform (AMTI, OR6-7-2000). Results: The mean load to produce an overwight status was 13.2 ± 4.0 kg for young and 11.7 ± 3.4 kg for older adults. The significant level adopted was p≥0,05. When normalizing by body weight, the OA presented lower FRS peaks in comparison to YNG group at both speeds. On the other hand, the OA presented higher second peak of the vertical force (Fz2) in the fast speed condition in comparison to the YNG. Conclusion: Directly simulated overweight may not be able to promote significant changes in the unload quantities, arising from bodyweight, that may influence the FRS.

title: The concept of convergence and its pitfalls

description: Abstract In the new media vocabulary, “convergence” has become an extremely popular concept. In this article we analyze both its technical and cultural significance. In particular, this last dimension is associated with the work of Henry Jenkins. Investigating its origins, popularity and fundamentally its ideological implications, we make clear how it translates a series of cybercultural utopias while legitimizing the asymmetries of power between producers and consumers of culture.

title: VASCULAR FUNCTION AND NITRITE LEVELS IN ELDERLY WOMEN BEFORE AND AFTER HYDROGYMNASTICS EXERCISES

description: ABSTRACT The regular practice of physical exercise may reduce the oxidative stress and the risk factors for cardiovascular diseases. This study aims to evaluate serum levels of nitrite and changes in cerebral arterial resistance and cholesterol in elderly women submitted to hydrogymnastic training. The sample was composed of 40 women with overage age of 69.21 ±5.27 years old, separated randomly into an intervention and a control group. Nitrite concentration was analyzed through Griess reaction. The arterial resistivity was observed by Doppler ultrasound, and the cholesterol was determined using colorimetric enzymatic method. The water exercise program lasted 16 weeks. It was seen an increase in NO2 (p=0.003), reduction in right common carotid artery resistance (p=0.024), TC (p=0.003) and LDL (p=0.001) cholesterol in the WG. There was a negative correlation between NO3 and RVA, r = -0.221 and p=0.049 and between NO3 and CT (r = -0,269 and p=0,016) after intervention. The hydrogynmnastic program promoted favorable changes in nitrite levels, arterial resistivity and cholesterol in the elderly women.

title: Apostilles around the journalistic discourse on crime and insecurity: figurations of the victims and the perpetrators in Argentine television news broadcasts

description: Abstract This article is the product of the first approaches to the ways in which the central characters of the television news about crime and insecurity in open television channels in Argentina and its construction in the story as victims or victimizers are figured. It is a set of initial inferences drawn up within the framework of a larger project entitled “From ownership to reception.Comprehensive study of the productive circuit of the news about crime and insecurity in the television news programs with the highest audience in Argentina “. It starts from the idea of figuration proposed by Traversa (1997) and re-read by Fernández and Tobi (2009), in order to identify chains of operations with respect to a specific discursive regime as a construction. From this point of view, it is possible to recognize certain significant recurrences in the wayin which victims and perpetrators are figured in television journalistic discourses that are part of the corpus under study.

title: COMPARISON OF METABOLIC PARAMETERS IN CHILDREN AND ADOLESCENTS WITH AND WITHOUT INSULIN RESISTANCE

description: ABSTRACT The aim of the study was to compare the behavior of metabolic parameters, blood pressure, and obesity indicators in children and adolescents with and without insulin resistance. Sixty-one overweight children (6 to 18 years) underwent anthropometric measurements of body mass (BM), height and waist circumference (WC), blood pressure (BP), bioimpedance (relative (%F) and absolute fat (BF)), and blood collection for determination of glucose, insulin, and lipid profile (TG, CT, HDL-C, LDL-C). The BMI z-score was used to classify nutritional status and the HOMA-IR index (&gt; 2.5) for insulin resistance. Participants were divided into two groups, insulin resistant (IR, n= 27) and non-insulin resistant (NIR, n= 33). Regardless of age, children and adolescents with excess weight and IR presented higher BM, WC, BMI, %F and BF (kg), TG, and plasma insulin than their NIR counterparts, who in turn presented higher LDL-C. The groups did not differ in nutritional status (BMI z-score); however, in the comparison between the undesired proportions of the metabolic components, only three presented alterations with significant differences between the groups (TC, LDL-C, and TG). It is concluded that IR influences the development of dyslipidemias in this age group, especially TG.

title: Tomographic characterization of edentulous areas before rehabilitation with single implant

description: Abstract Introduction Imaging resources are indispensable to assist the professional dental surgeon in the formulation of the diagnosis and preparation of an adequate treatment plan for the patient, being essential for the successful rehabilitation with dental implants. Objective The purpose of this cross-sectional study was to characterize the edentulous areas of patients who will be rehabilitated with single osseointegrated dental implant in the aesthetic area of the maxilla by means of computerized tomography and correlate parameters of interest. Material and method Fourteen cone beam computerized tomographies were evaluated in a program according to the following parameters: distance from the cementoenamel junction (CEJ) to the bone crest (BC), distance between the BC and distance between the dental crowns of the teeth adjacent to the prosthetic space (PS), bone width and height of PS, thickness of the palate in the region of the second premolars and molars as well as the horizontal and vertical thickness of the soft tissue in the PS region. Result and discussion The results were analyzed by means of descriptive statistics and the Spearman Correlation test. Weak and moderate correlations and no statistically significant differences were found in most comparisons (≤ 0.29 and ≥ 0.30 ≤ 0.49, respectively). Only for the correlation between PS mucosa thickness versus distance between CEJ and BC in the mesial tooth to PS was found significant statistical difference (p = 0.03) and moderate correlation (r = 0.56). Conclusion Cone beam computerized tomography is a viable tool for the maxillofacial region because it allowed the measurement of several parameters of soft and hard tissue of the buccal cavity useful for planning with dental implants, which may increase the predictability of successful rehabilitation treatments.

title: Strategic Planning and Management of Food and Agribusiness Chains: The ChainPlan Method (Framework)

description: Abstract Purpose The objective of this paper is to improve the method for the strategic planning and management of food and agribusiness chains. Design/methodology/approach Several research methodologies are used to develop the ChainPlan methodology. The theory (literature review) provided the basis on which to build a preliminary framework ten years prior. Then, empirical application of the initial method provided insights regarding needed additions to and subtractions from the original method. These insights, combined with continued research on advances in the theories, contributed to further development of the ChainPlan methodology Findings A method is proposed to fill the theoretical gap regarding the strategic planning applied to agribusiness chains. The ChainPlan method is a theoretical-empirical method, built based on the academic literature and perfected over the years through its application in several productive chains Originality/value Many authors have proposed a method to build strategic plans in organizations, but when planning agribusiness chains is concerned, the academic discussion revolves around the coordination of agribusiness chains and analyses to be applied in this sector. This article fills this theoretical gap and proposes a tool, which is a specific strategic planning method to be applied in agribusiness chain
