title: Acid ascorbic influence in gold nanorods growth with longitudinal plasmon band in near infrared – NIR

description: ABSTRACT The present work reports the ascorbic acid effect (0,60-0,98 µM) on the aspect ratio (AR) of gold nanorods with bands of longitudinal plasmon (LP) in the near infrared (958 -1085 nm), grown by seed-mediated chemical route. Cloroauric acid-1mM as precursor agent was used, obtained from a stock solution prepared by dissolving metallic gold (99,99%) in aqua regia. Benzyldimethylhexadecylammonium chloride (BDAC) and cetyltrimethylammonium bromide (CTAB) at molar ratio 0,75 (BDAC/CTAB) as surfactants were used. Scanning electron microscopy images implemented with a transmitted electron detector and absorption spectra revealed that the AR reaches a maximum of 7,3 and a band of PL of 1085 nm for a critical concentration of ascorbic acid of 0,68 µM, equivalent to a molar AA/Au3+ of 1,5. As ascorbic acid increase to 0,98 µM, the AR decreases up to 6 and consequently, its PL band decreases up to 958 nm.

title: Obtaining bioabsorable scaffolds from PLGA and IR blend with the addition of hydroxyapatite

description: ABSTRACT The aim of this paper is the obtainment of bioactive scaffolds from poly (lactic acid-co-glycolic acid) (PLGA) and polyisoprene (IR) polymer blends with different additions of hydroxyapatite (HAp) as an alternative for tissue engineering. For the preparation of the polymer solutions, the PLGA/IR blend and the HAp were dissolved in chloroform. Subsequently, the scaffold was processed by electrospinning, varying the dis-tance between the syringe and the collector. Scaffolds chemical and phase composition were characterized by zeta potential, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Scanning electron microscopy (SEM) was used to evaluate the morphology and for the cytotoxic behavior the cellular viability analysis methodology was used. The zeta potential value of the HAp was -22 mV and the FTIR and XRD were consistent with the literature. The SEM images allowed the analysis of the mean size and standard deviation of the obtained fibers, demonstrating a significant difference among the samples. The results showed the great influence of the distance between the collector and the tip of the syringe and the blend/HAp ratio, and the scaffold obtained with the largest collector/ syringe distance and the highest HAp/blend ratio showed fibers with a smaller mean size and greater homogeneity and low cellular cytotoxicity.

title: Infrared spectroscopy analysis on charcoal generated by the pyrolysis of Corymbia. citriodora wood

description: ABSTRACT Wood pyrolysis has been use for centuries to obtain charcoal. Nonetheless, the study of wood components altering by the pyrolysis temperature is crucial to determine the charcoal’s properties. The present research aims to evaluate by FTIR the chemical altering of wood submitted to various pyrolysis temperatures. Sam-ples of Corymbia citriodora species were submitted to temperatures of 240 °C, 280 °C, 320 °C and 400 °C in a fixed bed reactor filled with N2. The FTIR analysis was performed in the wood residues after pyrolysis. The results showed that cellulose and hemicelluloses presented more susceptibility to thermal degradation than other wood components. It could be observed chemical altering in the wood residue obtained between 240 °C and 280 °C. In addition, the wood residue obtained for treatments over 280 °C presented characteristics simi-lar to vegetal charcoal. There are a continuous change of the wood due to the temperature of the pyrolysis by the change of bands intensity and by the bands shift. The FTIR analysis allowed the evaluation of the wood’s pyrolysis process and its chemical variations with the temperatures applicate.

title: Study of behavior alloy Ti and 316L in to simulated body fluid by electrochemical techniques

description: ABSTRACT In this work, Ti-316L stainless steel was produced, and its electrochemical behavior was characterized. Ti-steel alloys were produced using an induction furnace, by mixing commercial Ti and 316L stainless steel. X-ray diffraction analyses showed the presence of both the materials, Ti and 316L, in the samples produced. The elemental composition of the materials was determined by optical emission spectroscopy and energy-dispersive spectroscopy, which showed similar quantities of both the elements. Both commercial 316L stainless steel and Ti–steel were studied in simulated biological fluid for imitate a like composition of body blood plasma. Electrochemical experiments conducted at 37°C indicated the stable passive polarization behavior of the Ti-steel alloy. Furthermore, the electrochemical behavior of the 316L stainless steel was also analyzed for comparison purposes. Corrosion velocities were determined using the Tafel method and corrosion resistances were obtained using the electrochemical impedance spectroscopy. The Ti-steel exhibited better protection capacity, compared with the commercial 316L steel. The corrosion velocity and the passive current density of the Ti–steel alloy were lower than those exhibited by the 316L stainless steel.

title: The use of the Modified Early Obstetric Warning System (MEOWS) in women after pregnancies: a descriptive study

description: Abstract Objectives: to evaluate the modified early obstetric warning system (MEOWS) in women after pregnancies in a tertiary hospital in Brazil. Methods: a descriptive study was conducted with 705 hospitalized women. Vital signs (systolic and diastolic blood pressure, heart rate, respiratory rate, temperature) and lochia were registered on medical records and transcribed into the MEOWS chart of physiological parameters. On this graphic chart, yellow alerts were used to present moderate abnormalities in vital signs, while severe abnormalities were presented in red. The presence of at least one red alert or two yellow alerts were triggered to indicate the need for medical evaluation. Results: although abnormalities were found in the physiological parameters of 49.8% of the women identified from MEOWS triggers, medical evaluation was only requested for three patients (0.8%). Conclusions: in a retrospective application of the use of MEOWS showed a significant number of patients had triggered in which the nursing team did not recognize 99.2% of cases. This finding could be attributed to the fact that MEOWS has not been yet adopted in this service as part of the nursing care. The application of this tool would result in a better care because critical situations would be recognized and corrected quickly, avoiding unfavorable outcomes.

title: Modulation of the Conduct of People with Disabilities in the Brazilian Context of Inclusive Education

description: ABSTRACT In this paper, we have analyzed how investments in the modulation of the conduct of people with disabilities have been made by the school inclusion policy in the Brazilian society since the last decade of the 20th century. In order to perform such analysis, we have used the notions of government by Foucault (2008a, 2008b), and modulation by Deleuze (2013) as analytical tools. By considering a group of legal documents that both guide and regulate the inclusion of people with disabilities in the regular school, we have attempted to show that the practices of the Brazilian State to act on the modulation of the conduct of those people aim to constitute subjects that are able to invest in the development of their individual competences along their educational process. In line with the school inclusion policy, organized in the arena of the neoliberal governmentality, different strategies have been used to minimize the social risk of exclusion of those subjects. Hence, the actions taken by the State are structured as a net and they articulate different sectors to guarantee equal conditions of access, participation and development to everyone and, thus, enhance participative, autonomous and learning forms of life throughout their lives, with flexible conducts and able to adapt to the continuing changes of our time.

title: Double Layer Frequency Selective Surface for Ultra Wide Band Applications with Angular Stability and Polarization Independence

description: Abstract In this paper, a double layer stopband Frequency Selective Surface (FSS) for Ultra-Wide Band (UWB) applications is presented. The proposed FSS consists of two cascaded conventional FSS, one with double square loops and other with square loops. The − 10dB frequency band from 3.00 GHz to 11.64 GHz is achieved, with a fractional bandwidth of 149 %. Effects of angular stability and polarization independence over the frequency response are investigated and conclusions are presented. In order to show transmission performance, the FSS was simulated by ANSYS HFSS. The FSS shows angular stability and polarization independence in entire UWB band (3.10 – 10.60 GHz). A prototype was built and measurements were performed. A good agreement between simulated and measured results was observed.

title: Electrochemical Behavior During the Zirconium Conversion Coating Formation on AISI 1006 Steel

description: This study investigated a conversion coating based on hexafluorozirconic acid solution on cold-rolled (AISI 1006) steel sheets, in situ, at different pH values and immersion times. Electrochemical characterization was carried out by electrochemical impedance spectroscopy (EIS) with hexafluorozirconic acid bath as the electrolyte. Laser scanning confocal microscopy (LSCM) was used to evaluate the morphology of the coating in situ, i.e., during the coating formation. According to the results, the polarization resistance (Rp) of the conversion coating is affected by the immersion time and by the pH of the conversion bath. The electrochemical analyzes point out conversion baths at pH between 3.5 and 4.5 and immersion times from 600 to 900 s as optimal operating conditions, achieving an average polarization resistance of 713 ± 107 Ω cm2.

title: A briefing game for school building design

description: Abstract The architectural design process is complex, as new technical, social, environmental and economical requirements are introduced, and this very scenario is applicable for school buildings. The quality of a school building depends on known design criteria, professional knowledge and feedback from building performance assessments. To attain high performance school buildings, the design process should add a multidisciplinary team via an integrated process. This article presents a design tool to structure a school building design briefing process. A participatory architectural programming phase is advocated and tested through a focal group, supported by a game called “Shuffle the School Building Design Deck” (SSBDD). The content of SSBDD and application procedure are based on known facts, needs and global concepts for learning environments in the twenty-first century. The briefing game considers the specific context of Brazil. Validation tests show positive results for productive architectural programming for school buildings. SSBDD has potential for global contexts, including translations for other building types.

title: Effectiveness of Solution-Focused Group Counseling on the Mental Health of Midwifery Students

description: Abstract Objective The present study was conducted with the objective of investigating the effectiveness of solution-focused group counseling (SFGC) on promoting the mental health of midwifery students. Methods The present study is an intervention-based study with a pretest, a post-test, and a control group. The statistical population included all of the midwifery students studying in the midwifery department of the Bam University of Medical Sciences, Kerman, Iran, who filled out the General Health Questionnaire (GHQ) in the screening phase. In the second phase, 40 individuals, having a low level of mental health based on the cutoff score of 23, were selected and randomly divided into 2 groups (intervention and control), each group with 20 participants. The intervention group participated in 5 sessions of 75 minutes for SFGC. Then, the post-test was held in both groups and the data analysis was conducted using the Mann-Whitney and the Kruskal-Wallis test with IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, NY, USA). The significance level was considered as p &lt; 0.05. Results The findings showed that the mean of the post-test mental health scores of the intervention group (14.5 ± 50.35) and of the control group (23.6 ± 35.83) showed a statistically significant difference (p &lt; 0.0001). Moreover, the comparison between the mean scores of the mental health subscales (physical symptoms, stress, social performance, and depression) showed a statistically significant difference in these groups, and SFGC improved physical symptoms, stress, social performance, and depression in the members of the intervention group. Conclusion Solution-focused group counseling may improve all levels of mental health. This type of counseling is recommended to be used to solve the psychological problemsand to improve the mental health of students, as well as of the staff of the health system.

title: Studies on structural, morphological, and optical properties of Cr2O3 nanoparticles: synthesized via one step combustion process by different fuels

description: ABSTRACT This research presents a novel one–step solution combustion synthesis to obtain nano-structured Cr2O3 from chrome nitrate solution and one fuel such as aspartic acid (Asp) or Lysine (Lys), or Autor Restrihydroxymethylaminomethane (Tris) or ethylenediaminetetraacetic acid (Edta). Once obtained, the ashes were calcined at 500°C. The powders were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy with Fourier transform (FTIR), UV-Visible Spectroscopy (UV-VIS) spectroscopy and Brunauer–Emmett–Teller (BET) techniques. These powders will be used in solar absorbing surfaces: in composites (o cermets) and painted coatings. Within the obtained ashes and calcined powders, it was identified a Cr2O3 crystalline structure corresponding to the rhombohedral system and to the R-3c spatial group. The average crystallite size was determined for ashes and calcined powders, this value was in nanometric range between 29 and 45 nm, where for ashes were in general minor than calcined powders in all cases. It is probable that with an increment of the temperature, crystallite size would grow. A specific area of 167 m2/g was determined for asp-ashes. This was a highest value observed in specific literature and it could be used in catalysis reactions, while the area values of ashes was higher than calcined powders value for each fuel. The average particle size observed through TEM resulted in 50 nm to 100 nm approximately. The determined Energy band gap resulted in 3.055eV to 3.078 eV approximately. The Energy band gap slightly increased with calcination temperature. Further trials and investigation will confirm the mentioned tendencies.
