title: CATALYTIC OXIDATION OF ISOPROPYL ALCOHOL OVER PLATINUM BASED CATALYST: A STUDY OF THE EFFECT OF METHYL CELLULOSE ON Pt PARTICLES DISPERSION OVER MULLITE

description: Abstract Isopropyl alcohol (IPA) catalytic oxidation remains one of the most popular techniques to remove volatile organic compounds from indoor places. In our study, catalytic oxidation of IPA was investigated on catalysts based on platinum deposited on mullite (Al6Si2O13), known for its excellent thermal stability. Pt/Al6Si2O13 catalysts were prepared by impregnation with and without methyl cellulose (MC) and were tested in order to study the influence of MC on the platinum particle dispersion over the support. The catalytic reactivity was compared with Pt/α-alumina and Pt/SiO2. Moreover, the resulting materials were characterized by BET, XRD, TEM and H2-chemisorption. This study showed that platinum exhibits better dispersion on alumina sites than silica sites. This can be due to a strong interaction between platinum and alumina, leading to a higher dispersion of platinum species. Furthermore, the addition of MC enhanced the Pt dispersion over the mullite, leading to an improvement in the catalytic performance.

title: LANGUAGE PRACTICES IN THE CONTEXT OF INTERNATIONALIZATION IN A FEDERAL INSTITUTE: SCHOOL SIGNS AND THEIR GLOTOPOLITICAL EFFECTS

description: ABSTRACT Based upon the theoretical-methodological support of the sociology of discourse by the Bakhtin Circle (BAKHTIN, 2016; VOLÓCHINOV, 2017), especially concerning the notion of expressiveness, in dialogue with the glotopolitical approach (GUESPIN, MARCELLESI, 1986), this paper aims at raising some reflections on the language practices within school signs. We take into account the context of internationalization at a technological federal institute in order to understand through a discursive-dialogical view what are the glotopolitical effects implied into practices of this nature. It is assumed that those practices act as a political intervetion towards the school linguistic landscape (SPOLSKY, 2004), and therefore, being the result of choices not randomly taken, decisions made previously, that with regard to the material analized, shows the option by which languages are to be selected to make part of the shool signs at that institution, as well as the priority order regarding the way they tend to be inscribed on the signs under analysis.

title: Method for the post-occupation technical evaluation of the quality of social housing communal areas

description: Abstract Several housing programs have been conceived and implemented in the last few decades in Brazil, with the aim to reduce the housing shortage. Despite the efforts to develop social housing, a substantial share of projects has had quality failures in the use phase, which represent costs to society. Previous research has been limited to the evaluation of housing units, leaving a gap in the evaluation of the communal areas of housing projects. This research study proposes a method to evaluate the quality of communal areas of social housing projects. By using Design Science Research as a methodological approach, tools for data collection and metrics for construction pathologies and non-conformities in communal areas were proposed. The method considers requirements of building performance and accessibility technical standards, and covers the evaluation to three elements of communal areas: building facades, sidewalks and parking spaces, and internal circulation areas of buildings. The method was tested on a sample of 10 social housing projects in the Metropolitan Region of Porto Alegre, RS, Brazil. The main contribution of this investigation is the development of the method for the evaluation of communal areas, which can be used to assess the technical quality of those areas in a fast and standardised way.

title: Physical and chemical properties of chicken mortadella formulated with Moringa oleifera Lam. seed flour

description: Abstract The objective of this study was to evaluate the effect of the addition of Moringa oleifera Lam. seed flour for partial fat replacement in chicken mortadella on physicochemical characteristics, chemical composition, and lipid oxidation. Four mortadellas were prepared: C (control), T1, T3, and T5 (addition of 1%, 3%, and 5% of moringa seed flour, respectively). T5 mortadella had the lowest lipid content (p &lt; 0.05), whereas C mortadella had the highest (p &lt; 0.05). The addition of 5% of moringa seed flour affected color parameters, leading to an increase in L*, a*, and b* values in comparison with the control. Color changes (ΔE) in T3 and T5 mortadellas were the lowest among the samples during a 90-day storage period at 4 °C. The addition of 3 or 5% of moringa seed flour promoted a reduction in lipid oxidation during storage. Moringa seeds have antioxidant activity and, therefore, have the potential to be used as a natural functional ingredient in meat products. The addition of 3% of moringa seed flour seemed to be ideal for chicken mortadella, as it reduced lipid content and promoted lipid stability without causing noticeable color changes during the 90 days of storage.

title: A METHODOLOGY TO OBTAIN ANALYTICAL MODELS THAT REDUCE THE COMPUTATIONAL COMPLEXITY FACED IN REAL TIME IMPLEMENTATION OF NMPC CONTROLLERS

description: Abstract Model Predictive Control, MPC and NMPC, and real-time optimization, RTO and D-RTO, are known to help plant operability through the mitigation of impacts caused by external disturbances. However, the usage of these tools in industry requires overcoming some challenges, for instance: accurate models of the process, particularly in regard to nonlinearities; suitable computational time for obtaining the solution of large-scale problems and model mismatch between the RTO or D-RTO and NMPC. In this paper, we present a methodology to obtain analytical model predictions based on a Hammerstein structure to represent the process nonlinearities, reducing the computational effort in real-time applications. Unlike most common approaches that transform NMPC internal models, described by differential-algebraic equations (DAE), into an approximate system of nonlinear algebraic (NLA) equations using, for instance, orthogonal collocation, in the proposed approach, the obtained NLA is an exact description of the original DAEs system. The proposed algorithm was applied to a non-isothermal CSTR (continuous stirred tank reactor) integrated with an optimization layer. The results show that the proposed structure presented a significant reduction in computational time without performance loss, when compared with the NMPC using a rigorous model. Moreover, the proposed strategy demonstrated good performance in tracking the targets sent by the optimization layer, without model mismatches between layers.

title: ENERGY AND EXERGETIC EVALUATION OF THE MULTICOMPONENT SEPARATION OF PETROCHEMICAL NAPHTHA IN FALLING FILM DISTILLATION COLUMNS

description: Abstract Multicomponent separation of synthetic petrochemical naphtha (hexane, cyclohexane, toluene and xylene) was carried out in a falling film distillation sequence with heat supply using a vapor chamber (thermosyphon). Tests were carried out by varying feed flow rate and temperatures of the feed and the vapor chamber in two ways of heat supply: isothermal and with a vapor chamber temperature profile. Regarding the distillation behavior of the multicomponent separation with the proposed falling film column, it was verified that the lower values of the studied variables and the profile temperature mode promoted the best results for hexane recuperation. With an indirect sequence of three columns, hexane mass fraction in the top column increases to the value of 0.82. Higher thermodynamic efficiency was found for two columns of the sequence in comparison with the conventional ones. This behavior is related to smaller energy consumption, showing a total energy reduction of 12% compared to the same separation performed in a conventional unit. Energy and exergetic efficiency values were higher than 95% and 85% in the three columns used. These analyses demonstrated that the falling film separation proposal is an energy efficient arrangement and could be considered for multicomponent separation.

title: Fishes community composition and patterns of species distribution in Neotropical streams

description: Abstract: The ichthyofauna of streams in the Neotropical region is not yet fully known. This study aims to investigate the ichthyofauna composition of six streams of the Ijuí River sub-basin, Rio Grande do Sul State, inserted in the Uruguay River basin, as to contribute to the knowledge of fishes species richness and distribution in the south of Brazil. Sampling was carried out between July 2015 and May 2016, bimonthly, using the technique of electric fishing to collect the fishes. Spatial variations (per sampled stream) in the ichthyofauna composition were tested with a permutational multivariate analysis of variance. In total, we collected 5,029 individuals from 55 species, 13 families and five orders. From these species, 17 are endemic to the Uruguay River basin. Five species alone represented approximately 70% of the ichthyofauna abundance sampled. Our hypothesis that the fish community composition is not homogeneous along the streams sampled was confirmed and we observed that species complexity increases from the upstream closest area to the downstream according to the river continuum concept.

title: A new inventory for fishes of headwater streams from the rio das Cinzas and rio Itararé basins, rio Paranapanema system, Paraná, Brazil

description: Abstract: The rio das Cinzas and rio Itararé basins are important tributaries of the rio Paranapanema, a major left-bank tributary of the upper rio Paraná basin. The upper reaches of both drainages intersect the northern portion of the APA Escarpa Devoniana (Devonian Escarpment Environment Protection Area, EPA), an area considered crucial for the preservation of biodiversity. This study aimed to provide an ichthyofaunistic inventory for headwater streams of the rio das Cinzas and rio Itararé basins, both within and off of the borders of the EPA, increasing the knowledge about the species already known from streams in the rio Paranapanema system. We found 32 fish species, representing five orders and 12 families. Siluriformes was the richest order followed by Characiformes. Ten species presented high abundance of sampled individuals, contributing with 85.0% of all specimens. Most species were classified as occasional (captured in less than 25% of the samples) and only two species were classified as constant (captured in more than 50% of samples), which may reflect the altitudinal gradient. We did not record any introduced species in the sampled streams, reinforcing the need of, at least, maintaining the original area of the EPA. We expanded the geographic distribution of Astyanax bifasciatus to the upper rio Paraná system, confirming the cases of faunal exchange among several drainage systems in the limits of the Ponta Grossa Arch. Finally, we identified three putatively undescribed species that show a large biodiversity knowledge shortfall for the region studied.

title: Financial-patrimonial elder abuse: an integrative review

description: ABSTRACT Objective: to analyze the available evidence in the nursing literature about financial-patrimonial elder abuse. Method: integrative review of articles indexed in the databases CINAHL, Scopus, Web of Science, LILACS and MEDLINE, from 2007 to 2017. The combination of controlled and uncontrolled descriptors was used in Portuguese, English and Spanish. Results: 15 studies developed in seven countries were included. In the thematic analysis, three categories emerged: epidemiological data, risk factors and institutions providing services to the elderly. The occurrence of this type of violence concomitantly to the other subtypes was highlighted among the most frequent. Final considerations: the literature points to important epidemiological data, risk factors and characteristics of this type of violence, including within institutions providing services to the elderly, in different countries, essential aspects for structuring and rethinking public policies for protection and appreciation of the elderly.
