25. Crystallization in Rapidly Quenched Fe-B-Si System with Additions of C and Cu
Glass formability and phase transformations in rapidly quenched ferromagnetic nano-structured (Fe85B15-xSix)98-yC2Cuy (where x=0; 5 and y=0; 1) systems were investigated. The consecutive crystallization stages of bcc-Fe and borides were determined by resistometry, differential scanning calorimetry and by thermogravimetry, where the values of important transf

26. Formation of Microphases and Constituents from Remaining Austenite Decomposition in API X80 Steel Under Different Processing Conditions
AbstractThe main goal this work is to evaluate the occurrence of the constituents and microphases observed in as-received API X80 pipe through the microstructures transformed from rich-carbon remaining austenite obtained via heat treatments. These heat treatments comprised austenitization at 1000 °C for 30 minutes, followed by annealing at 700 °C, 623 °C,

27. Transverse Motions of Rectangular Plates Resting on Elastic Foundation and Under Concentrated Masses Moving at Varying Velocities
AbstractThis study concerns the dynamic characteristics of a prestressed isotropic, rectangular plate continuously supported by an elastic foundation and carrying accelerating mass M. Closed form solutions of the governing fourth order partial differential equations with variable and singular coefficients are presented. For the two-dimensional plate problem,

28. Comparison of salivary levels of mucin and amylase and their relation with clinical parameters obtained from patients with aggressive and chronic periodontal disease
Objective Salivary mucin and amylase levels are increased in patients with chronic periodontitis (CP). Due to the fact that aggressive periodontitis (AgP) not only differs from chronic periodontitis in terms of its clinical manifestation, the aim of this study was to compare salivary mucin and amylase levels and their relation to the clinical parameters of

29. Umbrales para la determinación de la brecha digital: comparativa entre regiones desarrolladas
This piece of work has a main goal: setting a percentage scale that serves as a methodological basis in order to determine the digital breach existence or not among regions technologically developed. Once the scientific literature is analysed we can observe a clear deficiency because we don not have a studied basis that can determine under which parameters w

30. Transition temperature range of thermally activated nickel-titanium archwires
Objectives: The shape memory resulting from the superelasticity and thermoelastic effect is the main characteristic of thermally activated NiTi archwires and is closely related to the transition temperature range (TTR). The aim of this study was to evaluate the TTR of thermally activated NiTi archwires commercially available. Material and Methods: Seve

31. American tegumentary leishmaniasis: correlations among immunological, histopathological and clinical parameters
BACKGROUND: American tegumentary leishmaniasis has an annual incidence of 1 to 1.5 million cases. In some cases, the patient's immune response can eliminate the parasite, and the lesion spontaneously resolves. However, when this does not occur, patients develop the disseminated form of the disease. OBJECTIVE: To investigate the association between clin

32. Analysis of the transformations temperatures of helicoidal Ti-Ni actuators using computational numerical methods
The development of shape memory actuators has enabled noteworthy applications in the mechanical engineering, robotics, aerospace, and oil industries and in medicine. These applications have been targeted on miniaturization and taking full advantage of spaces. This article analyses a Ti-Ni shape memory actuator used as part of a flow control system. A Ti-Ni s

33. Deflection profile analysis of beams on two-parameter elastic subgrade
A procedure involving spectral Galerkin and integral transformation methods has been developed and applied to treat the problem of the dynamic deflections of beam structure resting on bi-parametric elastic subgrade and subjected to travelling loads. The case of the response to moving constant loads of this slender member is first investigated and a closed fo

34. Introduction of the rd29A: AtDREB2A CA gene into soybean (Glycine max L. Merril) and its molecular characterization in leaves and roots during dehydration
The loss of soybean yield to Brazilian producers because of a water deficit in the 2011-2012 season was 12.9%. To reduce such losses, molecular biology techniques, including plant transformation, can be used to insert genes of interest into conventional soybean cultivars to produce lines that are more tolerant to drought. The abscisic acid (ABA)-independent

35. Orçamento participativo: os limites da inovação institucional em Cuiabá-MT / Participative budget: the limits of institutional innovation in Cuiabá-MT/Brazil
The democratization process in Brazil in recent decades resulted from the combination of different forms of collective mobilization and changes in the state apparatus. The end of authoritarianism and democracy openness produced new sociopolitical arrangements of popular participation and enhancement of citizenship, through of creation of inclusive mechanisms

36. Evaluation of microbiological and biomimetic models in stereoselective metabolism of risperidone by high-performance liquid chromatography / Avaliação de modelos microbiológicos e modelos biomiméticos no metabolismo estereosseletivo da risperidona por cromatografia líquida de alta eficiência
Risperidone is an atypical antipsychotic drug. Its metabolism yields in two hydroxylated chiral metabolites, 7-hydroxyrisperidone (7-RispOH) and 9-hydroxyrisperidone (9-RispOH). The 9-RispOH metabolite presents the same pharmacologic activity of the parent drug risperidone. This led this drug to be marketed as drug under the generic name paliperidone. Studie
