title: Preparation and Characterization of Nickel ferrite Nanoparticles via Co-precipitation Method

description: Nickel ferrite (NiFe2O4) nanoparticles were synthesized using co-precipitation method. The X-ray diffraction (XRD) pattern was used to determine the structure of NiFe2O4 nanoparticles. The presence of NiFe2O4 nanoparticles was confirmed by the FT-IR spectrum. The details of the surface morphology of NiFe2O4 nanoparticles were obtained by Scanning Electron Microscopic analysis. The particle size of the NiFe2O4 nanoparticles could be determined by means of Transmission Electron Microscopy. This work aimed at the investigation of the dielectric properties such as the dielectric loss and the dielectric constant of NiFe2O4 nanoparticles at varied frequencies and temperatures. In addition, the magnetic properties of the NiFe2O4 nanoparticles were studied.

title: Thromboprophylaxis and maternal-fetal outcomes of women with serum markers for hereditary thrombophilia and previous obstetric complications

description: Abstract Objectives: to evaluate the maternalfetal outcomes of thromboprophylaxis with enoxa parin based on scoring system in women with serum markers for hereditary thrombophilia and previous obstetric complications. Methods: a retrospective study was undertaken based on data collected from clinical records. We included 54 pregnant women with serum markers for hereditary thrombophilia undergoing therapeutic intervention with enoxaparin in the period from November 2009 to December 2013. The initial dose of low molecular weight heparin was guided by a scoring system. The maternalfetal outcomes of previous pregnancies and, subsequently, the treatment were compared using the chisquare (χ2) test with the Yates correction and Fisher's Exact Test; p&lt;0.05 was considered significant. Results: we observed significant reduction in fetal/perinatal deaths (p&lt;0.05) and spontaneous abortions (p&lt;0.001) after intervention. The live births at fullterm delivery (p&lt;0.001) and live births at preterm delivery (p&lt;0.05) increased significantly after intervention. Conclusions: the therapeutic intervention with enoxaparin based on scoring system during pregnancy seems to improve the fetal prognosis.

title: The Carbon Nanotubes Effect into Single-lap Joint Failure Modes and Load Capacity: a Macromechanical Analysis

description: This study investigates the influence of the adhesive (epoxy resin) thickness and the dispersions of non-functionalized carbon based nanostructures (carbon nanotubes - CNT) on mechanical properties of single-lap bonded joints. To achieve this goal, three CNT concentrations (0.5%, 1.0% and 2.0% m/m); and three different bondline thicknesses (0.05 mm, 0.15 mm and 0.40 mm) were evaluated. The mechanical properties were measured using the apparent shear tensile test, based on ASTM D5868. The results showed that the addition of 1.0 wt% CNTs improved the interface strength, leading to an increase on delaminated areas in failure region up to 55.36% and also improving the peak force up to 13.85%. Decrease in adhesive thickness from 0.40 mm to 0.05 mm promoted a stress redistribution inside adhesive layer improving the peak force up to 13.91%. CNT seems to promote changes in failure modes, light fiber tear (LFT) failure significantly increases up to 45.96%, indicating that interface strength between adhesive and adherent was improved.

title: Does money matter less to evangelical candidates?

description: Abstract This article analyzes the impact of campaign spending on the voting record of individual candidates in legislative elections in Brazil. We more specifically examine the existence of a Jacobson effect for candidates with access to other resources providing leverage to their campaigns. For the 2014 elections for Federal and State Deputy, we find money has less impact on the voting record of candidates presenting themselves as pertaining to an evangelical church. To identify this religious framing of individual campaigns, we resort to the official nickname candidates are allowed to use in electoral campaigns in Brazil. This technique has been successfully applied in previous research. The causal mechanism behind this lesser effect of money on the voting record of candidates evoking a religious connection represents the symbolic and real power of Protestant Churches in the electoral process in Brazil. This result is similar to other studies showing that the value of money in election campaigns varies depending on other candidate characteristics. Candidates who have other mechanisms at their disposal to access and mobilize potential voters, such as the support of a church either in the form of an institutional endorsement, access to voters or unaccounted funding, are less dependent on officially accounted for resources than other competitors.

title: THE ROLE OF CONNECTORS IN THE CO-CONSTRUCTION OF IDENTITY IMAGES: THE USE OF THE MAS IN ELECTORAL DEBATES

description: ABSTRACT: This study is part of a broader research whose purpose is to investigate whether the establishment of discourse relations and its marking through connectors have implications for the co-construction of identity images. Looking for additional evidence for this research and adopting contributions from the Modular Approach to Discourse Analysis, this paper studies the connector mas employed by candidates for public office in two electoral debates, one municipal and the other presidential. The objective is to verify to what extent mas, in signaling the discursive maneuvers performed by the candidates, is an important piece in the game through which they (de)construct identity images. Analysis revealed that the 55 occurrences of the connector signaled two groups of discursive maneuvers. By using the mas through which the candidate signals maneuvers of attack to the opponent (mas for hetero-attack), he tries to construct an unfavorable image of the other and a favorable one of himself. But by using the mas through which the candidate signals maneuvers in which he attacks himself (mas for self-attack), he tries to attribute to himself values such as humility and modesty, as well as anticipate future criticism from the adversary.

title: Description and evaluation of experimental models for uterine transplantation in pigs

description: ABSTRACT Objective: To evaluate the technique of uterine transplantation and the use of drugs used in the process of immunosuppression. Methods: We included 12 sows, and immunosuppression was performed with minimal doses of cyclosporine, and cross-match was done to exclude the possibility of blood incompatibility. Hysterectomy was performed in the donor under general anesthesia, with the removal of the aorta and inferior vena cava in monobloc, and anastomosis of these vessels was made in the recipient. Results: Six experiments were performed, and on the immediate postoperative period, five animals had good reperfusion. However, on the seventh postoperative day, histological analysis showed rejection in five animals. Conclusion: The experimental model of uterine transplantation is feasible, but monitoring doses of immunosuppressants is pivotal to prevent rejection episodes.

title: Ab initio LSDA+U Study of Optical Properties of RVO4 (R = Eu, Ho, Lu) Compounds

description: A first principles investigation at the pressure 7 GPa of the optical properties of RVO4 (R= Eu, Ho, Lu) orthovanadates in the framework of the density functional theory (DFT) using the linearized-augmented plane-wave method is reported in order to predict new optical materials for continuous-wave lasers. The electronic structure of all orthovanadates is studied in zircon-type structure. DFT+U (Hubbard parameter found to be 8eV) calculations predict an antiferromagnetic and nonmagnetic insulating ground states -at ambient conditions- for (EuVO4, HoVO4) and LuVO4, respectively. The results show that these vanadates can be good candidates for laser-host materials, and indicate the possibility of material design to optimize the laser-host materials. The rare-earth ion-doped crystals could enhance the laser performances and improve the isolation characteristic of the optical isolators.

title: Hydrogen Kinetics and Hydride Formation Effect on Zr-1Nb and Zr-1Nb-1Sn-0.1Fe Alloys for Nuclear Application

description: The purpose of this study was to investigate the kinetics of hydrogen absorption and hydride formation and their effect on the mechanical properties in Zr-1Nb and Zr-1Nb-1Sn-0.1Fe alloys, which were thermomechanically processed and gaseously hydrided at 320ºC under 10 bar hydrogen pressure. X-ray diffraction (XRD) confirmed the formation of α-Zr matrix after final heat treatment. The alloys absorbed almost the same amount of hydrogen, although with different kinetics. Absorption began almost immediately in Zr-1Nb alloy whilst in Zr-1Nb-1Sn-0.1Fe hydrogen absorption started after 11 h besides a faster hydrogen kinetics. Results showed that tensile strengths for both alloys were nearly independent of absorbed hydrogen. Fractographic examinations indicated ductile fractures for unhydrided condition whereas quasi-cleavage features were observed for all hydrided specimens.

title: Alcohol intake during pregnancy among parturients in southern Brazil

description: Abstract Objectives: to assess alcohol intake prevalence and identify associated factors among pregnant women in the municipality of Rio Grande, RS, Brazil. Methods: this was a crosssectional study which included all parturient women residing in the municipality who gave birth in 2013. Two outcomes were characterized: alcohol intake during pregnancy and excessive alcohol intake during pregnancy. In the analysis, proportions were tested using the Chisquare test, whilst Poisson regression was used in the multivariate analysis. Results: 9.4% (CI95%= 8.210.5) of the 2,685 parturient women studied reported having consumed alcohol during pregnancy, with beer being most common beverage. Following adjustment, the factors associated with alcohol intake in pregnancy were: age ≥30 years, brown skin colour, living without a partner, low schooling, tobacco smoking and illicit drug use, having had more children and late onset of prenatal care. Excessive alcohol intake was found in 12.7% (CI95%= 8.616.9) of those who reported drinking during pregnancy and the factors associated with this practice were age ≥30 years, lower schooling and illicit drug use. Conclusions: this study found high alcohol intake during the gestation period and identified women more susceptible to this practice. There is an evident need for health professionals to work on preventing and handling alcohol intake among pregnant women in the municipality

title: Nutritional assessment of Esmeraldan adult population (Ecuador)

description: ABSTRACT Objective To analyse the nutritional status of the adult population in Esmeraldas by means of anthropometric measurements, the input of macro and micronutrients in the diet, and the adequacy estimation of nutrient intake by hispanic Dietary Reference Instakes along with the sex and the age influence. Methods Nutrient intake data were obtained by personal interview with the application of two 24 hour recalls (weekend and weekday). The anthropometric indicators analysed were body mass index, waist circumference and blood pressure. Nutriplato version 2.0 software was used for the two 24-hours food recall surveys data processing, and for the respective calculations of macronutrients, micronutrients and Dietary Reference Intakes. Means and standard deviations were calculated for anthropometry, nutrient intakes and Dietary Reference Instakes. The General Linear Model was applied to identify differences in relation to nutrient intakes considering sex, profession, body mass index, group, origin and day of the week as factors. Results Statistical analysis showed significant differences mainly in carbohydrates, fiber, calcium, phosphorus, iron, sodium, iodine, and vitamin E. Dietary intakes were compared with the Federación Española de Sociedades de Nutrición, Alimentación y Dietética Dietary Reference Intakes requirements and calcium, potassium, iodine, riboflavin, pantothenic acid, biotin, vitamin D, vitamin E, fiber, monounsaturated fatty acids and polyunsaturated fatty acids are below the Dietary Reference Instakes in all ages and gender subgroups. The anthropometric results obtained indicated that 67.0% of the population were overweight and obese, the 87.7% of the adults suffered from prehypertension and the waist circumference indicated that 73.0% of the subjects were established in the range of high risk of cardiovascular disease. Conclusion Priority nutrition actions and interventions are needed to be developed in Esmeraldas adult population.
