title: DEPENDENCY OF NANOFLUID RHEOLOGY ON PARTICLE SIZE AND CONCENTRATION OF VARIOUS METAL OXIDE NANOPARTICLES

description: Abstract Impact of the nanoparticle size and concentration on the rheology of ethylene glycol based nanofluids containing nanoparticles of five different metal oxides is investigated. Particle mass concentrations ranged from 5 to 20 wt %. Types of the nanoparticles and their particle size are TiO2 (30 nm, 50 nm), MgO (20 nm, 40 nm), ZnO (10-30 nm, 35-45 nm, 80-200 nm), SiO2 (20-30 nm, 60-70 nm) and CuO (40 nm, 80 nm). A stress controlled rheometer fitted with a cone-and-plate system is employed for the rheological characterization of the nanodispersions at temperatures between -5˚C and 35˚C. The non-linear measurements reveal that nanofluids of CuO (40 nm), ZnO (10-30 nm, 35-45 nm) and MgO (20 nm, 40 nm) particles exhibit non-Newtonian shear thinning behavior at particle mass concentrations higher than 5 %. No appreciable shear thinning is observed for the dispersions of TiO2 (30 nm, 50 nm) and SiO2 (20-30 nm, 60-70 nm) particles. Strong dependency between relative viscosity of the suspensions and particle size and loading is observed. Temperature, on the other hand, plays a marginal role in the relative viscosity of the suspensions. The shear viscosity measurements indicated the presence of particle size and concentration dependent apparent yield stress for CuO and ZnO nanofluids. Investigated nanofluids do not exhibit any thixotropy during their rheological characterization. Finally, viscoelastic measurements suggest that nanofluids are free of gel formation.

title: Antioxidant activity of black bean (Phaseolus vulgaris L.) protein hydrolysates

description: Abstract The objective of this work was to study the effect of enzymatic hydrolysis of black bean protein concentrate using different enzymes. Bean proteins were extracted and hydrolyzed over a period of 120 min using the enzymes pepsin or alcalase. The protein hydrolysates’ molecular weight was assayed by electrophoresis and the antioxidant activity was evaluated by the capturing methods of free radicals ABTS●+ and DPPH. Electrophoretic results showed that the bands above 50 kDa disappeared, when the beans protein was subjected to hydrolysis with pepsin. The bean protein hydrolysate obtained by hydrolysis with alcalase enzyme, showed higher antioxidant activity for inhibition of the radical ABTS●+. However, the hydrolysates obtained by hydrolysis with pepsin had higher antioxidant activity for inhibition of the radical DPPH. The use of pepsin and alcalase enzymes, under the same reaction time, produced black bean protein hydrolysates with different molecular weight profiles and superior antioxidant activity than the native bean protein.

title: SYNTHESIS OF ZEOLITE 4A FOR OBTAINING ZEOLITE 5A BY IONIC EXCHANGE FOR FULL UTILIZATION OF WASTE FROM PAPER INDUSTRY

description: Abstract In order to minimize environmental impact zeolite A was synthesized using waste from the paper industry. This waste is composed of cellulose, kaolin and calcium carbonate. Waste purification was carried through thermal and chemical treatment, which consisted of initial calcination, acid washing with HCl, then calcination of the solid fraction to obtain metakaolin and evaporation of the liquid fraction to obtain CaCl2. Zeolite 4A was produced by static autoclaving under hydrothermal synthesis at different temperatures, crystallization times and NaOH concentrations. As a source of aluminum and silicon metakaolin was used. The synthesis of zeolite 5A was performed by ion exchange with CaCl2. After that, the waste paper (in natura and HCl treatment) and the zeolites 4A and 5A were characterized by XDR, SEM, FTIR, AAS and thermal analysis. The temperature is a key factor in zeolite synthesis at lower concentrations allowing one to obtain zeolite 5A by ion exchange with zeolite 4A.

title: Microbiological quality of meals served in nursing homes in the city of Ponta Grossa, Paraná

description: Abstract The aim of this study was to analyze the microbiological quality of meals served in nursing homes in the city of Ponta Grossa, Paraná, before and after the training of food handlers. The first stage was to perform a checklist conforming with current legislation. The second consisted of the collection of 4 food samples from each location and a microbiological investigation in accordance with the relevant legislation. The third was the training of food handlers in relation to good food handling practices. The fourth was a further microbiological analysis of new samples. The application of a checklist showed that the locations met the requirements of current legislation. Of the 40 samples analyzed, 17.5% (7 samples) were unfit for consumption. Among the unfit samples 15% (6 samples) had coliforms at 45 °C, 2.5% (1 sample) had coagulase-positive staphylococci, 2.5% (1 sample) had Bacillus cereus and 2.5% (1 sample) had Salmonella sp. The results of this study show the importance of controlling the quality of food served to an age group that is prone to health risks.

title: Health teaching as an object of research in academic graduate programs: an analysis of the Pro-Ensino na Saúde

description: This study aimed to understand the inductive potential of the Pro-Saude Program as an education policy for academic graduate programs and for the development of research on Health teaching, using data from 31 projects and interviews with 17 coordinators. We identified the participation of 59 graduate programs, the realization of 395 research studies and the education of 423 professionals in 24 of the 31 projects. The investment in this program strengthened a qualified education process and the development of research in Health teaching, in the expectation of changes in the daily routine of the academia and the health service. Pró-Ensino na Saúde is recognized as an inductive policy, fostering collaborative networks and knowledge production, but it still faces the challenge of establishing itself as an effective constituent of a public policy of Health education and work.

title: Evaluation of the factorial structure of the Body Shape Questionnaire: exploratory or confirmatory factorial analysis?

description: ABSTRACT Objective: To conduct a discussion about the strategies to assess the factorial structure of psychometric instruments using like an example the Body Shape Questionnaire (BSQ). Methods: We evaluated seven different factorial models of the BSQ that were obtained through exploratory factorial analysis (EFA) and are presented in the literature. The confirmatory factor analysis of these models was performed for study sample using the indices chi-square per degree of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis index (TLI), Root Mean Square Error of Approximation (RMSEA), and Weighted Root Mean Square Residual (WRMR). Convergent and discriminant validities were assessed by the average variance extracted and coefficient of determination among BSQ factors, respectively. Reliability was assessed using the composite reliability and the Cronbach's alpha coefficient. Results: 739 female college students with a mean age of 20.4 (standard deviation = 2.4) participated. All models assessed showed adequate fit for the study sample, however, the discriminant validity was inadequate in the all models. Furthermore, composite reliability of the models was adequate. Conclusion: Although all tested models of BSQ showed good psychometric indicators, it is worth noting that they were obtained in different samples using the EFA and without theoretical plausible justification for the construction of the factors, which may make it difficult to choose a model for clinical use. Therefore, considering the importance of preserving the theoretical concept during the development of an instrument, we suggest to researchers and clinicians who are cautious about the use of models without theoretical support.

title: Structural characterization of vegetative organs of the endangered Brazilian native species Hesperozygis ringens (Benth.) Epling

description: Abstract The aim of this study was to describe the structural characterization of Hesperozygis ringens (Benth.) Epling vegetative organs. For this purpose, leaves, stems and roots of the endangered Lamiaceae were collected from a population located in Santo Antão, Santa Maria municipality, Rio Grande do Sul, Brazil. Results demonstrated that the H. ringens leaf blade presents glandular and non-glandular trichomes as well as two morphs of diallelocytic stomata, which are usually found above the epidermis level. The petiole is concave on ventral face and convex on its dorsal face, containing glandular and non-glandular trichomes as well as stomata in the epidermis. These types of trichomes were also detected in the stem. In addition, the presence of intercellular spaces within the organ is highlighted. Stomata above epidermis level also occurred in the stem. Phenolic idioblasts were found in the cortical region of plant root and deposit of lipophilic substance was observed in phloem cells. Great amount of apparently two different crystals were detected in all organs. Information obtained in this study provides knowledge about the characterizationof H. ringens, which may be used to distinguish characters of taxa and can help understand the species survival in its occurrence sites.

title: Immunophenotyping lymphocyte and acute phase proteins in canine X-linked muscular dystrophy

description: Abstract Duchenne Muscular Dystrophy (DMD) is the most common X-linked muscular disease affecting humans. The Golden Retriever Muscular Dystrophy model (GRMD) is considerthe most suitable for several studies. This assay aims to quantify lymphocyte subpopulations CD4, CD5, and CD8, and standardize, the serum electrophoretic profile, to understand their contribution to the pathologic process in normal Golden Retriever dogs (GR group) and dystrophic´s (GRMD group), through the umbilical cord blood, in dogs aged from 2 to 3 months (GR II and GRMD II), and in dogs over 1 year of age (GR III and GRMD III). No significant differences were observed between the CD8+ lymphocyte subpopulations of the groups studied. The CD4+ and CD5+ lymphocyte subpopulations were significantly higher in the GRMD III group compared to the GR III group. Twenty-two different proteins in the gel were identified. The serum concentrations of the proteins belonging to the GR I and GRMD I groups were significantly lower than those of the other groups. We show that expression of acute phase proteins are worst during the aging of the dogs. We hope to expand knowledge to better understand the GRMD model and the translational data.

title: Spray-dried porcine plasma added to diets contaminated with aflatoxins and fumonisins shows beneficial effects to piglet health

description: Abstract This study was aimed to analyze the effects of spray-dried porcine plasma (SDPP) on the health of post weaning piglets challenged with diets contaminated with aflatoxins and fumonisins. Fifty-six male piglets (7.15 ± 0.61 kg) were allocated in four groups: CTL group received a regular diet; SDPP group received a regular diet and 6% SDPP; MYC group received a diet containing 300 µg/kg aflatoxins and 8,000 µg/kg fumonisins; group MYC+SDPP received 300 µg/kg aflatoxins, 8,000 µg/kg fumonisins and 6% SDPP. The animals that received the experimental diet containing mycotoxins (MYC group) had lower weight gain at the end of the experiment compared to the other treatments. Animals receiving SDPP showed decreased urea levels throughout the experiment (P&lt;0.05). Animals from MYC group presented an increased on reactive oxygen species (ROS) and thiobarbituric acid reactive substances (TBARS) levels and decreased catalase activity (P&lt;0.05). In contrast, SDPP prevented the increase of ROS and TBARS and stimulated superoxide dismutase activity (P&lt;0.05). In conclusion, diet contaminated with mycotoxins (group MYC) caused subclinical intoxication in the piglets, as observed by the increase on free radical’s production and lipid peroxidation. Conversely, SDPP presented a protective effect, minimizing the effects of oxidative stress caused by aflatoxins and fumonisins ingestion.
