title: Facial trauma and background level: a study on the population’s perspective

description: ABSTRACT Purpose: to verify the population’s understanding on facial trauma, according to their level of schooling. Methods: an observational, cross-sectional, quantitative, documentary study conducted, based on 852 interviews carried out in two Brazilian state capitals. The association between the levels of schooling and varied knowledge of facial trauma was investigated. The data were analyzed with Pearson’s chi-square test or Fisher’s exact test, with a margin of error of 5%. Results: there was a statistically significant association between the participants’ schooling and their understanding on the consequences of trauma in: functions (p = 0.001), mouth mobility (p = 0.005), and dental issues (p = 0.003). In the most affected population, schooling was also associated with youth (p = 0.001) and adults (p = 0.044). Regarding causes, there was association with falls (p = 0.034) and traffic accidents (p = 0.034). There was association with bikers (p = 0.016) and motorcyclists (p = 0.001) as the population with greater propensity. Schooling was associated with all the professionals. Concerning the consequences to the victim’s life, there was association also with general health (p = 0.049), household chores (p = 0.001), and social life (p = 0.001). Recklessness was the only cause with an association (p = 0.004). Schooling was associated with previous knowledge of trauma (p = 0.001). Conclusion: their understanding on the consequences of trauma, most affected population, main causes, professionals involved in the treatment, repercussion for people’s lives, and previous knowledge of the subject increased along with the levels of background.

title: The relationship between dysphagia and clinical and cognitive aspects in elderly patients presented with dementia

description: ABSTRACT Objective: to relate the risk of dysphagia and aspects of eating behavior to the cognitive aspects of elderly people with dementia. Methods: 35 elderly patients with Alzheimer or vascular dementia were submitted to clinical and cognitive assessments as well as to a questionnaire for assessing appetite/eating disorder and the Dysphagia Risk Evaluation Protocol (DREP). Appropriate statistical tests were applied adopting a significance level lower than 0.05. Results: mild dementia occurred in 16 cases, moderate, in 14, and severe, in 5. Complaints of choking/coughing in the medical history, and signs of dysphagia in the DREP, occurred in 9 and 25 elderly patients, respectively, with no differences regarding the type and severity of dementia. Patients presented with dysphagia and alterations in the oral and pharyngeal phases of DREP, were older. Alterations in the pharyngeal phase were associated with poorer performance in the Mini-Mental State Examination (total score, attention/calculation, language). Changes in appetite/weight/eating habits were associated with signs of dysphagia, increasing severity of dementia and functional impairment. Conclusion: choking/coughing and signs of dysphagia were high. Changes in appetite/weight/eating habits were related to the severity of dementia and presence of dysphagia, and cognitive disorders and old age were associated with dysphagia.

title: Role of Silicon in the Microstructural Development and Properties of Ti-15Nb-xSi Alloys for Biomedical Applications

description: Abstract Ti-Nb alloys are attractive for biomedical implants and the addition of Si can lead to an improved set of properties. This study investigates the effect on the microstructures and properties of solution-treated Ti-15Nb-xSi alloys followed by furnace cooling (FC), and water quenching (WQ). Based on the results, Si acts as a β-stabilizing element by increasing the β volume fraction from 13%–36% in FC samples to a range from 0%–0.55% Si. The elastic modulus decreased under both conditions and reached approximately 63 GPa in WQ samples with 0.35% Si due to an increased α” unit cell volume. On the other hand, hardness increased with increased Si content under FC and WQ conditions to a maximum of 313 HV in the WQ sample containing 0.55% Si.

title: Association between severity of the temporomandibular disorder, neck pain, and mandibular function impairment

description: ABSTRACT Purpose: to investigate the possible association between the severity of the temporomandibular disorder, cervical pain, and mandibular function impairment. Methods: is a cross-sectional, descriptive study, conducted with 32 individuals with temporomandibular disorder, categorized by degree of severity, according to the Fonseca Index. Using the diagnosis criteria for temporomandibular disorder, the likely etiological factors for the disorder were established, as well as the intensity of the functional disability, resulting from cervical pain and of the mandibular impairment. The data obtained were statistically treated, adopting the significance level of 5%. Results: the mean age was 33.8 years, 90.6% being females. As for the degree of disorder, 56.3% presented severe TMD, followed by 28.1% showing a moderate one. The myogenic etiology was present in 93.7% of the patients. Cervical pain was present in 90.6% of them, of which, 59.4% presented a mild disability, and 25%, a moderate one. Considering the mandibular function, 46.9% of the patients presented a low, 40.6%, a moderate, and 12.5%, a severe impairment. There was a statistically significant association between cervical pain and mandibular function (p = 0.011). However, although there was an increase in cervical disability and in mandibular impairment as the severity of the TMD also increased, these associations were not statistically significant (p = 0.178 and p = 0.102, respectively). Conclusion: it can be stated that there is a higher prevalence of severe TMD and of myogenic origin, and that cervical pain influences, directly, the mandibular function, which is not necessarily related to the severity of the temporomandibular alteration. Likewise, such severity does not present a relationship to mandibular function impairment either.

title: Content and layout development and validation of a vocal health guide for older adults

description: ABSTRACT Purpose: to develop and validate the content and layout of an educational guide on promoting vocal health of older adults. Methods: a methodological study, conducted in two stages: 1 - Development of the guide as an educative technology; 2 - Qualification of the educative material with validation of the guide’s content, layout and suitability by 13 judges (speech-language-hearing pathologists) and legitimization of the educative material by the target population, 9 older adults. The validation of the guide by the judges and older adults was based on the content validity index. Results: the aspects of objectivity, structure, presentation and relevance of the content were considered pertinent by the judges with an approximate score average of 0.92. However, some words were substituted or removed to bring more clarity to the reader, without loss to the overall message, in addition to the suggestions that were accepted for the final version. The older adults returned a positive assessment. Conclusion: the educative guide was validated regarding the aspects of content, layout and suitability for the vocal health promotion of older adults. Their knowledge of voice health is expected to promote the quality of life and benefit active and healthy aging.

title: Association between diabetes and vestibular dysfunction: an integrative review

description: ABSTRACT Purpose: to identify, in the literature, the factors associated with the development of vestibular dysfunctions in individuals with type 2 diabetes mellitus (DM2). Methods: an integrative review of the literature, whose survey was conducted in the databases ISI, SciELO, LILACS and PubMed, using the following descriptors: “type 2 diabetes mellitus”, “vertigo”, “dizziness”, and “vestibular diseases". Articles published in the last 10 years that answered the research question (“What factors are associated with the development of vestibular disorders in individuals with DM2?”) were included in the study. Results: the search returned 426 articles, 10 of which met the eligibility criteria. Most of the participants of the selected studies who had vestibular dysfunctions were women over 40 years old and had more than one comorbidity related to DM2, the main one being the systemic arterial hypertension (SAH). According to the literature, the physiology of the inner ear allows small glucose alterations to influence its normal functioning, which makes diabetic individuals more susceptible to developing vestibular dysfunctions. Conclusion: according to this study, DM2 can trigger or contribute to the manifestation of vestibular dysfunction, whose main associated factors are advanced age, female gender, and various comorbidities, as dyslipidemia, SAH and metabolic syndrome.

title: Investigation on Internal Crack Defects in Medium Carbon Steel by Soft Reduction

description: Abstract This paper investigated the effect of soft reduction amount increasing from 1-4mm with a cooling time of 120s and 180s to reduce the internal crack defects by analyzing the microstructure, crack morphology, extent and nature of grain boundary ferrite, centre macrosegregation, and fracture surfaces in medium carbon steel. It was found that the large extent of grain boundary ferrite with coarse morphology weakens the bonding force of the PAGB and makes it brittle with the initiation of micro-cracks. The sever centre carbon macrosegregation of 1.3 takes place at cooling time of 180s with different reduction amounts, which becomes homogeneous at cooling time of 120s. The results show that the length of inter-granular and trans-granular cracks reaches 20mm with the carbon macrosegregation index of 1.3. The carbon macrosegregation index of 1.3 with a small fraction of 15% is enough to deteriorate the centre macrostructure of the ingot. The cleavage facet size of fracture surfaces is remarkably decreased below 100um at soft reduction parameters of 2mm/120s, 3mm/120s, and 4mm/120s with micro-cracks less than 100um, which reveals that the microstructure of specimens with these soft reduction parameters is more resistant to the cracks propagation.

title: Kinetic Study of a Bacterial Cellulose Production by Komagataeibacter Rhaeticus Using Coffee Grounds and Sugarcane Molasses

description: Abstract Biotechnology can be used to convert waste into valuable products. In this context, there is bacterial cellulose (BC), a natural biopolymer that can be transformed into several useful materials, but its production is limited due to the high cost of the culture media used for its industrialization. In this work, BC was produced from the bacteria Komagataeibacter rhaeticus, using coffee grounds, sugarcane molasses and ethanol. The experiments were carried out under static conditions. The products were collected every 48 h, with a total period of 240 h. The maximum BC production (11.08 g.L-1) was obtained in a culture medium supplemented with coffee powder, hydrolyzed cane molasses and the addition of 1% (v/v) ethanol. The results show that the use of different carbon sources of the evaluated by-products are viable alternatives in reducing costs in BC production.

title: Microstructure and Wear Behavior of NbC-Reinforced Ni-Based Alloy Composite Coatings by Laser Cladding

description: Abstract This work aims to evaluate the influence of laser power and reinforcement feeding rate on the microstructure, hardness, and wear behavior of NbC-reinforced Hastelloy C276TM alloy composite coatings. From a dual feeding system, one-step metal-matrix composite coatings were deposited with 10, 30, and 50% mass feeding of NbC powder with laser powers of 1.5 and 3.0 kW. Coatings deposited with 1.5 kW and 30% NbC showed some degree of porosity due to a combination of NbC feeding rate and melting pool temperature. Laser power and NbC feeding rate altered the melting efficiency and substrate burn-in shape, remarkably influencing the dilution. The composite microstructure was comprised of Ni-γ (FCC) dendrites with interdendritic network carbide which, in turn, ranged from lamellar-like M6C to blocky-like conjugated MC-M23C6 carbide. Primary petaloid-like MC [Nb] carbide was formed from a 30% reinforcement rate on, whilst a considerable number of unmelted particles was observed for 50%. The higher the reinforcement feeding rate, the higher the carbide fraction and better wear performance of low heat-input specimens. Synthesis with high heat-input sheds a light on the deleterious effect of the dilution and is not an option to enhance the wear performance.

title: Analysis of Carbides in Multi-component Cast Iron Design Based on High Entropy Alloys Concepts

description: Abstract Nowadays, the concept of high entropy alloys (HEAs) has expanded the limits of metallurgy and high-quality metallurgical HEAs ingots have already been successfully obtained on an industrial scale. High Chromium Cast Irons (HCCI) and Multi-Component Cast Irons (MCCI) are known to be a useful material for applications when abrasion resistance is required. Inspired by the concepts of high-entropy alloys, a base HCCI was modified, by adding other carbide-forming elements, at concentrations higher than what is currently used, in order to develop a new class of white cast iron, High Entropy White Cast Iron (HEWCI). The characterization of carbides precipitated during the HEWCI solidification was performed by scanning electron microscopy, energy dispersive spectroscopy, electron backscattered diffraction (SEM/EDS/EBSD) and X-ray diffraction (XRD). With the characterization techniques employed, the as-cast microstructure obtained of HEWCI is composed of approximately 50% of austenite matrix and 50% of different types of carbides, MC, M7C3 and M2C carbides.

title: On the Heat Capacity of Pure Elements and Phases

description: Recently, a model was proposed to predict cv as a function of temperature from the absolute zero to the melting temperature applied. This solution was based on critical grain nucleation to determine the volume, which contains the total number of modes for a particular equilibrium and non-equilibrium state to calculate the density of state (DoS), which is strongly dependent on the nucleus radius for both pure element and compound. Electronic and rotational energies were regarded for both elements and compounds in this formulation. The anomalies associated with cv can be easily considered in terms of their entropies, independent of their nature, as a local change in the DoS. Comparisons of cv for elements and compounds are performed against Thermodynamics software simulations and experimental data.

title: An Investigation on the Effect of Heat Treatment on the Compression Behavior of Aluminum Matrix Syntactic Foam Fabricated by Sandwich Infiltration Casting

description: Abstract In this research, syntactic foams including Al-7075 matrix and 2-4 mm low-cost pumice particles were manufactured via a novel casting method called as sandwich infiltration. According to physical evaluations, thanks to extremely porous structure of pumice, density values of the fabricated foams varied between 1.42 and 1.61 g/cm3. Porosity values were between 40.62% and 47.39%. Microstructural observations showed that there was a perfect infiltration between Al matrix and pumice particles because of correct process optimization (process pressure of 0.1 MPa, matrix melting temperature of 720°C and filler pre-temperature of 500°C). Furthermore, T6 treatment was applied to samples to comprehend effect of the aging on mechanical properties. The results indicated that there was an affirmative relation between the heat treatment and quasi-static compressive properties of the fabricated foams. The highest compressive strength, plateau stress and energy absorption values were measured as 64.4 MPa, 74.3 MPa and 34 MJ/m3 for heat treated samples. It was also observed that although the highest energy efficiency of 0.89 was calculated for heat treated sample, there was no relation between the heat treatment and efficiency. As for failure modes, as-cast samples exhibited ductile barreling characteristic whereas T6 treated foams indicated brittle v-shape fracture.

title: Proposition of an Empirical Functional Equation to Predict the Kinetics of Austenite to Ferrite Transformation in a Continuous Cooled IF-Ti-Stabilized Steel

description: Abstract The kinetics of phase transformations in isothermal processes is well described by the classic JMAK model. However, it is known that most industrial facilities employ continuous cooling processes and, for this condition, the JMAK model is adapted but, sometimes, without success. Considering the importance to predict critical temperatures, the present work proposes an alternative empirical functional equation to describe the kinetics of steel phase transformation under continuous cooling, being useful when the JMAK use is not successful. In this study, the continuous cooling austenite to ferrite transformation was experimentally characterized by dilatometry for an IF-Ti-stabilized steel. The proposed equation was compared with the classic adapted JMAK model regarding to evaluate its efficacy to fit the dilatometric experimental data. Using the constants obtained by the both model fittings as input parameters, a computational simulation was performed to determine the CCT diagram of the IF-Ti steel. The proposed functional equation was efficient to predict the critical temperatures, the kinetics of austenite decomposition and the CCT diagram of the studied steel. The results predicted by the proposed model greatly met the experimental data measured by dilatometry.

title: Sustainable Composites Based on Recycled High-density Polyethylene/mica

description: Abstract Composites based on recycled high-density polyethylene (rHDPE) and muscovite mica, with different rHDE/mica ratios (100/0, 95/5, 90/10, 85/15 and 80/20, weight percentage) were prepared in an internal mixer with roller-type rotors at temperature of 170 ºC for 10 minutes. The materials obtained were characterized by tests of density, Shore hardness D and melt-flow index, along with infrared spectroscopy, thermogravimetry, differential scanning calorimetry and scanning electron microscopy. The hardness analysis confirmed the action of mica as a reinforcing load in the matrix, but this effect stabilized at around 15%. The TG analysis showed that the 85/15 composite presented slightly better performance than the 80/20, indicating that mica, up to 15%, caused disorganization of the polymer structure instead of reinforcing it. The DSC results revealed that the composites had slightly lower melting temperatures than the matrix. The FTIR spectrum indicated there was no chemical interaction between the rHDPE and mica.
