title: Evaluation of the influence of the monomer (methyl methacrylate) / wax (cetyl palmitate) and process methodology on the preparation of nanocapsules containing phase change material via emulsion polymerization

description: ABSTRACT In this work, nanocapsules containing Phase Change Material (PCM) were produced by means of the encapsulation process via emulsion polymerization, using the cetyl palmitate wax as encapsulated material and the methyl methacrylate monomer as encapsulant, through two different process methodologies. The wax / monomer mass ratio was also evaluated in the production of the nanocapsules. The samples were submitted to characterizations, with the objective of evaluating the stability and physical integrity of the nanocapsules after drying in the stove, their thermal behavior (DSC), their morphological aspects (SEM), average particle size, solids content and cyclic operational potential. Analyzing the obtained results, it was observed that both the production process methodology and the variation of the wax / monomer ratio directly influenced the formation of the nanocapsules and the average particle size, and the samples produced through Method II presented better results regarding formation of the nanocapsules with particle size of the order of 200 nm, with high wax / monomer ratio and stable to cyclic temperature processes.

title: Between State, society and family: the care of female caregivers

description: ABSTRACT Objective: to investigate the care provided by family female caregivers of elderly dependents who have been monitored by public home care and its social repercussions, discussing the facets between State, society and families. Method: descriptive cross-sectional study, with 45 caregivers of elderly patients accompanied by Home Care Services. Data were collected by means of a structured script. The discussion was elaborated in light of the works "Cuidado e cuidadoras: as várias faces do trabalho do 'care'" (Care and female caregivers: the several faces of the care work) and "Gênero e trabalho na França e no Brasil" (Gender and work in France and Brazil). Results: Most caregivers were women (95%) who performed home care at several places and incorporated hospital equipment into everyday life. They have been caregivers for four and a half years, working 18 hours a day on average; they presented average age of 55 years; 82% were ill, and 43% had no income. Conclusion: the study demonstrated the relevance of the care of female caregivers to society as well as their invisibility to public health and social policies.

title: Chemical composition and dimensional stability of three eucalypts wood

description: ABSTRACT In this study correlations between chemical composition and dimensional stability of Eucalyptus botryoides. Eucalyptus paniculata e Eucalyptus tereticornis were evaluated. Specimens were prepared from five different positions in radial direction, corresponding to 0, 25, 50, 75 e 100%, from pith to bark. For physical analysis, samples mass and dimensions were measured above saturation point, at conditioned temperature (20°C and 65% of relative humidity) and oven dried (103 ± 2°C). In each step density at 12% (ρb), as well tangential (βT), radial (βR) and volumetric (βV) shrinkage were calculated. Samples from same positions were chemical evaluated concerning to soluble extractives in ethanol-toluene, insoluble lignin, hemicellulose and α-cellulose. It has been observed similar behavior among eucalypt wood. Lignin and density showed positive correlation, both increasing from pith to bark, while hemicellulose presented negative correlation with density and extractives negative correlation with shrinkage.

title: Nursing professionals' knowledge regarding the management of waste produced in primary health care

description: ABSTRACT Objective: To evaluate the knowledge of Nursing professionals regarding waste management in primary healthcare services. Method: Descriptive study with a mixed approach, developed with 42 nursing professionals who worked in basic health units of a capital in the Brazilian Northeast Region. Quantitative variables were analyzed by the SPSS 20.0 program. Reports were processed by the IRaMuTeQ software, analyzed according to the descending hierarchical classification, and grounded on the Collective Subject Discourse. Results: Low knowledge scores were obtained, associated with specific socioeconomic and training variables. Analysis of collected reports allowed to identify three classes: "Inadequate waste disposal: first and main step"; "Correct disposal improves service quality and prevents diseases"; and "Consequences associated with incorrect disposal". Conclusion: The knowledge of professionals falls short of the expectations to adequately manage waste produced in primary health care and is concentrated on the initial steps, mainly the disposal process.

title: Effect of topical ozonetherapy on gingival wound healing in pigs: histological and immuno-histochemical analysis

description: Abstract In this study, the effects of ozonetherapy on secondary wound healing were evaluated histologically and immuno-histochemically. Material and Methods: 8 healthy pigs were used in this study. Six wounds with 10 mm in diameter were created through the punch technique on the palatinal gingiva of each pig. Ozone gas was applied on only 3 wounds (test group) and the remaining 3 were left to natural healing (control group). Biopsy samples were taken from one of the wounds in each group on the third day, from another wound of each group on the seventh day, and from another one on the tenth day. Routine histological analysis and immuno-histochemical staining were performed to investigate transforming growth factor-beta (TGF-β) and (VEGF) expressions. Results: No statistical difference was found between the test and control groups in terms of collagen fibers, epithelial formation and inflammation scores. A VEGF expression found in the test group was statistically higher than control group samples taken on the 3rd and 7th day. There was no statistical difference between the test and control groups in terms of TGF-β expression on any of the sampling days. Conclusion: The topical application of ozone gas could be effective in the early stages of wound healing by increasing the amount of VEGF expression. Clinical Relevance: Topical application of ozone gas may be effective in the early stages of oral wound healing.

title: Tooth whitening affects bond strength of adhesive systems in enamel

description: ABSTRACT This study presents how the tooth whitening affects the bond strength and fracture type of three distinct adhesives — a conventional, a self-etching, and a universal adhesive — in enamel. Health bovine incisors were prepared by flattening the labial surface; part of these teeth was submitted to whitening treatment with a peroxide-based product (WhiteGold Office© 35%). The Single Bond©, AdheSE©, or Single Bond Universal© adhesive system were used to adhere a block of restorative resin to the flat surface of the teeth. Sticks measuring 10x1x1 mm were prepared and used in microtensile tests; they were also employed to examine the type of fracture. The results are analyzed with a two-way ANOVA. For both whitened and non-whitened specimens, the adhesive systems did not give statistically different bond strength values. However, the fracture shape (classified into four types) varied from a cohesive enamel type fracture for the whitened samples to a predominantly cohesive resin type fracture for the non-whitened teeth. Therefore, the whitening procedure has exerted a weakening effect on enamel even after 21 days post-treatment.

title: Effect of fluoride application during radiotherapy on enamel demineralization

description: Abstract Radiation-related caries are one the most undesired reactions manifested during or after head and neck radiotherapy. Fluoride application is an important strategy to reduce demineralization and enhance remineralizaton. Objective: To evaluate the effect of the topical application of fluoride during irradiation on dental enamel demineralization. Material and Methods: Thirty molars were randomly divided into three groups: Non-irradiated (NI), Irradiated (I), Irradiated with fluoride (IF). Each group was subdivided according to the presence or absence of pH-cycling (n=5). In the irradiated groups, the teeth received 70 Gy. The enamel's chemical composition was measured using Fourier Transform Infrared Spectrometry (organic matrix/mineral ratio - M/M and relative carbonate content - RCC). Vickers microhardness (VHN) and elastic modulus (E) were evaluated at three depths (surface, middle and deep enamel). Scanning electron microscopy (SEM) was used to assess the enamel's morphology. Results: The FTIR analysis (M/M and RCC) showed significant differences for irradiation, pH-cycling and the interaction between factors (p&lt;0.001). Without pH-cycling, IF had the lowest organic matrix/mineral ratio and relative carbonate content. With pH-cycling, the organic matrix/mineral ratio increased and the relative carbonate content decreased, except for IF. VHN was influenced only by pH-cycling (p&lt;0.001), which generated higher VHN values. ANOVA detected significant differences in E for irradiation (p&lt;0.001), pH-cycling (p&lt;0.001) and for the interaction between irradiation and pH-cycling (p&lt;0.001). Increased E was found for group I without pH-cycling. With pH-cycling, groups I and IF were similar, and showed higher values than NI. The SEM images showed no morphological changes without pH-cycling. With pH-cycling, fluoride helped to maintain the outer enamel's morphology. Conclusions: Fluoride reduced mineral loss and maintained the outer morphology of irradiated and cycled enamel. However, it was not as effective in preserving the mechanical properties of enamel. Radiotherapy altered the enamel's elastic modulus and its chemical composition.

title: Parametric study and Analysis of Band Stop Characteristics for a Compact UWB Antenna with Tri-band notches

description: Abstract In this article, equivalent circuit modeling with study and analysis of band notch characteristics for a triple band notched UWB antenna has been discussed to develop a better understanding of the antenna functioning and its behavior. A small square ultra wideband antenna having overall size of 24 × 31 mm2 with tri- band rejections is designed and simulated using HFSS software. Very narrow band notching is accomplished by placing C slots and inverted C slot of different dimensions on the radiating patch which makes maximum space utilization without performance deterioration. The antenna operates from 3.1 to 14 GHz (VSWR &lt; 2) with the presence of 3 narrow band notches (VSWR &gt;2) of 3.3-3.7 GHz (WiMAX), 5.1 – 5.4 GHz (Lower WLAN and HIPERLAN/2) and 5.7 − 6 GHz (Upper WLAN) as shown by the simulated and measured results (VSWR&lt;2) of the UWB antenna, with and without the presence of triple notches, thus utilizing the maximum UWB bandwidth. The radiation pattern plots for simulated and measured results are also presented to validate the working of the antenna. This antenna can be a respectable candidate for future European and USA high capacity UWB applications. The group delay and peak gain plots are also found to be stable in the range of operation of the antenna. The study and analysis of the band notching is discoursed in terms of current distribution and impedance plots to provide a greater and better perception into the working of the antenna and hence an equivalent circuit for the tri-band notched UWB antenna has been proposed.
