title: Development and characterization of a soymilk Kefir-based functional beverage

description: Abstract Kefir is a fermented beverage that deserves special attention, since it has probiotic activity and unique sensory, nutritional, and therapeutic properties. Given that both kefir and soymilk are beneficial to human health, this study aimed to assess the physicochemical characteristics and acceptability of soymilk Kefir-based functional beverages (SKB) properly inoculated with lactobacilli strain after 16h of incubation at 37 °C. It was monitored lactobacilli cell viability, yeasts count, pH, titratable acidity, lipids, proteins, ash, total solid, carbohydrates, caloric values and acceptability of the products. Additionally was conducted a shelf-life study of SKB added of peach-flavor. The lactobacilli cell count ranged from 7.0 to 8.0 Log10 CFUmL-1 and pH values from 4.5 to 4.6. SKB samples with higher soymilk kefir percent presented higher lactobacilli cell count and lower lipid, ash, total solid, carbohydrate and caloric value. Results showed similar preferential rates for the SKB up to 30% of added soymilk kefir. The functional peach-flavored beverage presented appropriate pH value (4.3) and high viable cells count (7.0 Log10 CFUmL-1) up to the 28th day of cold storage, showed high acceptability (94.5%) and positive purchase intention (83.4%) among consumers.

title: LIQUID-LIQUID EQUILIBRIUM OF SYSTEMS COMPOSED OF SOYBEAN OIL + MONOACYLGLYCEROLS + DIACYLGLYCEROLS + ETHYL OLEATE + OLEIC ACID + ETHANOL AT 303.15 AND 318.15 K

description: Abstract Steady increase in prices of petroleum-based fuels and growing environmental concerns are boosting attention to alternative fuels. In this context, biodiesel has drawn attention as an alternative fuel, especially as a substitute to traditional diesel. Biodiesel is commonly produced from triacylglycerols and alcohol through transesterification reaction. Knowledge of equilibrium phase distribution of key components in transesterification systems is essential for a better understanding of the reaction pathway and for guiding the design and optimization of reactors and the products separation. This study reports experimental results and thermodynamic modeling of the liquid-liquid equilibrium of systems composed of soybean oil + monoacylglycerols + diacylglycerols + ethyl oleate + oleic acid + ethanol at 303.15 and 318.15 K. Experimental data were well correlated using NRTL, with a maximum deviation of 0.688%. As for UNIFAC, the deviations between predicted and experimental data ranged from 3.13 to 9.21%.

title: Non-isothermal decomposition kinetics of conductive polyaniline and its derivatives

description: Abstract The non-isothermal decomposition kinetics of conductive polyaniline (PANI) and its derivatives, poly(o-methoxyaniline) (POMA) and poly(o-ethoxyaniline) (POEA), was investigated by thermogravimetric analysis (TGA), under inert and oxidative atmospheres, using Flynn-Wall-Ozawa’s approach to assess the kinetic parameters of the decomposition process. The order of reaction was found to be dependent on the degree of conversion indicating that both the early and the later stages of polymer degradation were next the zero or pseudo zero order kinetics, whereas the intermediate stages follow a first order kinetics. The activation energy was found to be dependent on both the degree of conversion and PANI derivative. Activation energy values vary from 125 to 250 kJ/mol, to decompositions carried out under nitrogen, and 75 to 120 kJ/mol to oxidative atmosphere. Parent PANI presented the best thermal stability and suggesting that thermal stability is also influenced by derivatization and type of atmosphere used.

title: Elderly caring for the elderly: spirituality as tensions relief

description: ABSTRACT Objective: To investigate the forms of coping used to relieve tensions by elderly caregivers of elderly relatives and to know the type of support they receive from the Primary Health Care service at home. Method: A qualitative study with a theoretical-methodological contribution of Grounded Theory, carried out with 10 elderly caregivers interviewed between August 2014 and January 2015. Results: Participants use primarily religious coping to deal with adverse situations that arise in their lives; they attribute to the sacred the strength to continue to age and care for another elderly person at home. Religiousness was the main coping strategy used by the participants, but little recognized by the health service. Final considerations: It is recommended that the Primary Health Care service provide greater support to these caregivers and be attentive to the spiritual dimension as an auxiliary element in the process of comprehensive and inclusive health care of these elderly caregivers.

title: Epidemiological investigation of perinatal deaths in Recife-Pernambuco: a quality assessment

description: ABSTRACT Objective: to evaluate the completeness of perinatal death investigation sheets, stratified by age components. Method: descriptive study carried out in Recife, PE, in 2014. Among 308 perinatal deaths, 46 were excluded from this study due to association with congenital malformations, and 7 due to missing investigation sheets. Analysis included 255 deaths (160 fetal deaths, and 95 preterm neonatal deaths). The degree of completeness of 98 variables was calculated. They were aggregated into six blocks: identification, prenatal care, birth care, family characteristics, occurrence of death and conclusions and recommendations. Results: the median rate of completeness for perinatal death investigation sheets was 85.7% (82.8% for records of fetal deaths and 89.5% for records of preterm neonatal deaths). The best-filled information block was “identification” (96.1%), as well as its components: fetal (94.7%) and preterm neonatal (97.9%). The worst was “prenatal care” (69.8%), along with its components: fetal (73.8%) and preterm neonatal (67.4%). Conclusion: investigation sheets had good completeness; there were differences between variables and components of perinatal death.

title: Inactivation of Staphylococcus aureus in raw salmon with supercritical CO2 using experimental design

description: Abstract Considering the microbial safety of consumption of raw foods (Asian food), this study aimed to explore the inactivation S. aureus in raw salmon by supercritical CO2 treatment (SC-CO2). For this purpose, experimental design methodology was employed as a tool to evaluate the effects of pressure (120-220 bar), the depressurization rate (10 to 100 bar.min–1) and the salmon:CO2 mass relation (1:0.2 to 1:1.0). It was observed that the pressure and the depressurization rate was statistically significant, i.e. the higher the system pressure and depressurization rate, the greater the microbial inactivation. The salmon: CO2 mass relation did not influence the S. aureus inactivation in raw salmon. There was a total reduction in S. aureus with 225 bar, a depressurizing rate of 100 bar.min–1, a salmon: CO2 mass relation of 1:0.6, for 2 hours at 33 °C.

title: Evaluation of metals in tomato sauces stored in different types of packaging

description: Abstract There is a growing concern about health and food safety when it comes to processed food. In the present study, it has been hypothesized that tomato sauces contain high amounts of metals possibly leached from packaging. Concentrations of As, Cd, Pb, Cr, Ni, Sn and Sb were determined by ICP-MS in tomato sauces stored in metallic, plastic, cellulosic and glass packaging. Packaging composition was determined by XRF. This study has also determined Cr and Sn content, by GF AAS, in simulant solutions prepared to be in contact with the four types of packaging. The results showed that there was no significant difference between the concentrations of metals in products stored in different types of packaging (p&gt;0.05), except for Sn and Ni. Canned products presented higher concentrations of tin (0.19 mg/kg); and nickel contents showed a range of 0.05 to 0.1 mg/kg. The only metal that was in higher concentration than the established by law (0.1 mg/kg) was Cr (mean value of 0.3 mg/kg). The XRF identified the presence of chromium in plastic, cellulosic and metallic packaging, and tin only in cans. For simulant solution, the tin from cans was the only identified migrant and chromium migration was not detected.

title: Amperometric Electrochemical Platform for Hydrazine Determination Exploiting Reduced Graphene Oxide, Co(Salophen) and DNA: Application in Pharmaceutical Formulations Samples

description: The present work presents the development of a sensitive and selective amperometric sensor for the determination of hydrazine (HZ) in pharmaceutical formulations using a glassy carbon electrode (GCE) modified with a composite based on Co(Salophen), reduced graphene oxide (rGO) and deoxyribonucleic acid (DNA). The rGO/Co(Salophen)/DNA composite was characterized by using Fourier-transform infrared spectroscopy (FTIR), cyclic voltammetry, and amperometry. The proposed platform presented a well-defined voltammetric profile with a redox couple around 0.32 V vs. Ag/AgCl which showed excellent catalytic activity towards HZ oxidation. The peak current of HZ electrochemical oxidation on the proposed electrochemical platform have changed linearly with the HZ concentration in the range from 2 to 364 µmol L-1. The proposed platform presented sensitivity, limit of detection, and limit of quantification of 0.056 µA L µmol-1, 0.54 µmol L-1, and 1.64 µmol L-1 to HZ, respectively. The relative standard deviation for eight determinations using a solution of 50 µmol L-1 HZ was 0.85%. The proposed sensor was successfully applied for the determination of HZ in pharmaceutical formulations, and the recovery tests showed a good accuracy with recovery percentage between 99 and 101%.

title: Science competitions using technology: a study of the behavior of the participating schools in the CNC in Portugal

description: Abstract: In this work we investigate the dynamics of 143 schools of the 3rd cycle of Basic Education in Portugal, regarding the preparation and participation in online science competitions on curricular contents of Mathematics, Portuguese, Physics and Chemistry and Geology. An exploratory factorial analysis of empirical data concerning the competitions in 2015 was carried out, to analyze the characteristics inherent to schools’ performance. Four latent factors describing the schools’ behavior were identified: Quantitative Training, Qualitative Training, Proficiency and Users, which allowed us to verify that: (i) participation in mathematics competition is predominant; (ii) schools participating in two or three competitions present different preparation dynamics; (iii) schools involved only in Mathematics and Physics and Chemistry competitions seem to adopt a more articulated and efficient pedagogical strategy. Although all schools develop a preparatory work before competitions, the strategies used seem to be related to the combination of distinct disciplinary groups participating in the competitions.
