The particle morphology and surface texture play a major role in influencing mechanical and hydraulic behaviors of sandy soils. This paper presents the use of digital image analysis combined with fractal theory as a tool to quantify the particle morphology and surface texture of two types of quartz sands widely used in the region of Vitória, Espírito Santo, southeast of Brazil. The two investigated sands are sampled from different locations. The purpose of this paper is to present a simple, straightforward,reliable and reproducible methodology that can identify representative sandy soil texture *** test results of the soil samples of the two sands separated by sieving into six size fractions are presented and discussed. The main advantages of the adopted methodology are its simplicity, reliability of the results, and relatively low cost. The results show that sands from the coastal spit(BS) have a greater degree of roundness and a smoother surface texture than river sands(RS). The values obtained in the test are statistically analyzed, and again it is confirmed that the BS sand has a slightly greater degree of sphericity than that of the RS sand. Moreover, the RS sand with rough surface texture has larger specific surface area values than the similar BS sand, which agree with the obtained roughness fractal dimensions. The consistent experimental results demonstrate that image analysis combined with fractal theory is an accurate and efficient method to quantify the differences in particle morphology and surface texture of quartz sands.

Political discussions are characterized by conflicts of interest, and decisions are made based on negotiations. In general, participants need to reinforce their opinions and influence other participants. In this context, it is important to know how allies and opponents are positioned, in order to understand the discussion dynamics and plan adequate actions. This paper suggests the use of social network visualizations to explicit oppositions and alliances in order to support the understanding and following of political discussions. A system which supports these visualizations was built. An experiment performed to test the proposed visualizations showed to which extent they can be more efficient in identifying information about clashes and alliances than an online discussion system can.

The aim of this work is to demonstrate how public university hospital （UH） managers can improve the process of decision-making by using the measurement of economic value added to the society （EVAS） generated by these organizations. Thus, the economic values of the organization and its departments were calculated, according to the theory studied： measurement model of economic result of Slomski （1996）. It was considered the conduction of a case study in a public UH, evaluating its economic performance in a 3-year period. For the interpretation of results, the Data Envelopment Analysis （deA） which categorized the departments of the hospital studied as efficient or inefficient was used. This study revealed that managers can improve the decision-making process by using the EVAS, since it has been established that this measurement of economic value has sensitivity to identify which of the economic value drivers should be emphasized in the management.

Objective： To evaluate the response to clinical and surgical treatment of Walter Cantidio University Hospital patients who were diagnosed with Barrett＇s esophagus between 2012 and 2016. Methodology： From the database analysis of Walter Cantidio University Hospital＇s pathology service, we identified all patients with a diagnosis of Barrett＇s esophagus between 2012 and 2016. We analyzed the patients＇ medical records and collected epidemiological and clinical data. Results： 22 patients were included in the study, 13 of whom were surgically treated and 9 were clinically treated. The regression was 33.3% in the clinical group and 30.7% in the surgical group, with no statistical difference between these two groups. Conclusions： The results show synchrony with data from the medical literature regarding the response of Barrett＇s esophagus to clinical and surgical treatment.

The manufacture of goat Coalho cheese has become a potential mechanism for market expansion and *** study aimed to evaluate the influence of marination in red wine on the quality,safety,and stability of goat Coalho cheese produced in the Brazilian semi-arid *** were immersed in red wine at 6±1℃ for seven *** MC(marinated cheese)and CC(control cheese)were characterized during 28 days of storage(4±1℃).At the initial time(day zero),an irregular,porous,and spongy surface related to the moisture,fat globules,and protein network was observed on CC and MC,which had a similar fatty acid profile(17 saturated fatty acids,9 monounsaturated fatty acids,and 8 polyunsaturated fatty acids).The marination resulted in lower pH,greater hardness and chewiness,and less Na in the matrix(CC-253.12 mg.100 g^(-1);MC-129.02 mg.100 g^(-1)).Over 28 days,marination delayed MC degradation rates(lipid oxidation and proteolysis),with greater pro-tection against free radicals,a higher amount of total phenolic compounds,and antioxidant *** re-sults indicated a positive effect of wine marination on the physicochemical parameters of goat Coalho cheese,improving the quality,safety,and stability.
