25. Kelvin Viscoelasticity and Lagrange Multipliers Applied to the Simulation of Nonlinear Structural Vibration Control
Abstract This study proposes a new pure numerical way to model mass / spring / damper devices to control the vibration of truss structures developing large displacements. It avoids the solution of local differential equations present in traditional convolution approaches to solve viscoelasticity. The structure is modeled by the geometrically exact Finite Ele

26. High Order Impact Elastic Analysis of Circular Thick Cylindrical Sandwich Panels Subjected to Multi-mass Impacts
Abstract This study dealt with the dynamic model of composite cylindrical sandwich panels with flexible cores and simply supported boundary conditions under low velocity impacts of multiple large or small masses using a new improved higher order sandwich panel theory (IHSAPT). In-plane stresses were considered for the core and face sheets. Formulation was ba

27. Using a single tablet daily to treat latent tuberculosis infection in Brazil: bioequivalence of two different isoniazid formulations (300 mg and 100 mg) demonstrated by a sensitive and rapid high-performance liquid chromatography-tandem mass spectrometry method in a randomised, crossover study
The recommended treatment for latent tuberculosis (TB) infection in adults is a daily dose of isoniazid (INH) 300 mg for six months. In Brazil, INH was formulated as 100 mg tablets. The treatment duration and the high pill burden compromised patient adherence to the treatment. The Brazilian National Programme for Tuberculosis requested a new 300 mg INH formu

28. Stability of antimicrobial activity of peracetic acid solutions used in the final disinfection process
The instruments and materials used in health establishments are frequently exposed to microorganism contamination, and chemical products are used before sterilization to reduce occupational infection. We evaluated the antimicrobial effectiveness, physical stability, and corrosiveness of two commercial formulations of peracetic acid on experimentally contamin

29. Natural additives for poly (hydroxybutyrate - CO - hydroxyvalerate) - PHBV: effect on mechanical properties and biodegradation
In this work, the improvement of mechanical properties in biodegradable materials was obtained through the incorporation of natural and also biodegradable plasticizers and nucleation agents into the PHBV copolymer. PHBV production with different quantities of additives was obtained by extrusion followed by injection. The additives in the copolymer were effic

30. Simulação computacional de escoamentos reativos com baixo número Mach aplicando técnicas de refinamento adaptativo de malhas / Computational simulation of low Mach number reacting flows applying adaptive mesh refinement techniques.
It is the main goal of the present work to extend a numerical methodology based on both the use of an adaptive mesh refinement technique (AMR) and the use of a multistep, implicit-explicit time-step strategy (IMEX) to applications involving low Mach number reactive flows. Originally developed for incompressible flows, the Eulerian formulation of that methodo

31. A comunicação popular, o debate e o processo constituinte no Brasil (1977 - 1988) / The popular communication, discussion and constitutional process in Brazil
The period and theme that will be addressed in this dissertations concerns the debate and the constitutional process of formulation of the 1988 Constitution in Brazil, which began in 1977 on the occasion of the beginning of the distension and slow and gradual political opening of the New Republic Military Dictatorship, therefore, defined as the time frame be

32. Desenvolvimento e caracterização de microemulsão à base de óleo de sucupira (P. emarginatus Vog. Fabaceae) e avaliação da atividade antiinflamatória tópica / Development and characterization of oil sucupira microemulsion (P. emarginatus Vog. Fabaceae) and evaluation of topical anti-inflammatory activity
Pterodon emarginatus, popularly known as Sucupira Branca is a native species found in the Brazilian Savannahs in states of Goiás, Minas Gerais, São Paulo, Mato Grosso do Sul. Several studies have confirmed their therapeutic activities as antiinflammatory, antinociceptive, analgesic, antimicrobial, among others. The aim of this study was to develop a microe

33. Análise da qualidade de gelatina obtida de tarsos de frango e aspectos envolvidos no processo produtivo. / Quality analysis of gelatin made from chicken feet and production process aspects
This study features gelatin production as a new possibility in the production chain of broilers, through the use of chicken by-products. Given the lack of other works on sensory analysis of gelatins made with collagen extracted from chicken feet, the objective of this study was to assess the acceptability of that gelatin by evaluating its sensory qualities t

34. Estudo dos produtos químicos originados a partir da degradação do gel de clorexidina a 2%, por meio da Cromatografia Gasosa acoplada à Espectrometria de Massas / Study of chemicals derived from the degradation of 2 % chlorhexidine gel, by means gas chromatography coupled to mass spectrometry
The aim of this study was to determine, by means of gas chromatography coupled to mass spectrometry (GC-MS), products originated from the degradation of 2 % chlorhexidine digluconate (CHX) gel. Three gels were selected: commercial Gel_Chlorhexidina® (Maquira), 2 % CHX gel UNIARARAS (handled at the Pharmacy Education UNIARARAS) and 2% CHX gel prepared in lab

35. Citotoxic activity evaluation of essential oils and nanoemulsions of Drimys angustifolia and D. brasiliensis on human glioblastoma (U-138 MG) and human bladder carcinoma (T24) cell lines in vitro
The species Drimys angustifolia Miers and D. brasiliensis Miers, commonly known as "casca-de-anta", have in their leaves essential oils that can confer cytotoxic effects. In this study, we evaluated the citotoxic effects of the volatile oils from these two species. We also proposed a nanoemulsion formulation for each of the species and assessed the in vitro

36. Aproximações estabilizadas de escoamentos de fluidos viscoplásticos através de uma expansão seguida de uma contração axissimétrica
The effect of inertia in the flow of viscoplastic fluids through an expansion followed by a contraction is analyzed. The mechanical behavior is modeled by the Generalized Newtonian Fluid constitutive equation, with the viscosity function given by the SMD equation (de Souza Mendes and Dutra, 2004). The conservation equations of mass and momentum, together wit
