title: Enrichment of Copper, Lead, and Tin by Mechanical Dry Processing of Obsolete Printed Circuit Board Residues

description: Waste printed circuit boards (WPCB) residues were mechanically processed to concentrate their metal content aiming to reduce costs of the subsequent recovery of copper, tin, and lead. A fully dry route was proposed to avoid the generation of liquid effluents that would require additional treatment. Firstly, 10.7% of the residue was segregated by magnetic separation; the remaining nonmagnetic fraction was comminuted and sieved. Ceramic and polymer materials (1/3 of the total weight) concentrated in the finer and the coarser size fractions, while metallic materials (2/3 of the total weight) concentrated in the intermediate size fraction (90.7, 94.5, and 95.6% of the total copper, tin, and lead contained in the milled WPCB, respectively). The fractions between 0.3-1.20 mm were submitted to gravity separation using a zig-zag air classifier; enrichment of copper (from 43±11% to 68±5%), tin (from 10±3% to 17±1%), and lead (from 4±1% to 6.4±0.5%) were obtained.

title: Scanning Electrochemical Microscopy (SECM) Study of the Electrochemical Behavior of Anodized AZ31B Magnesium Alloy in Simulated Body Fluid

description: In this work, scanning electrochemical microscopy (SECM) was employed to study the corrosion behavior of anodized AZ31B magnesium alloy exposed to simulated body fluid. SECM measurements were carried out in surface generation/tip collection mode. The hydrogen evolution flux caused during corrosion of the magnesium alloy was oxidized at the ultra-microelectrode (UME). Thus, this experimental procedure allowed evaluating the effect of the anodic protection in this alloy from the SECM analysis of Z- approximation curves, cyclic voltammograms and topographic maps. The results evidence differences in the local electrochemical response of magnesium alloy in the anodized and pristine conditions. The main sites of H2 evolution were verified in the magnesium alloy without anodizing at short exposure times.

title: Mapping of Stressors in the Work of Expeditionary Brazilian Antarctic Program (PROANTAR)

description: ABSTRACT The Brazilian Antarctic Program (PROANTAR) conducts expeditions to Antarctica, where military and civilian are exposed to stressors. The present research mapped the environmental, occupational and interpersonal stressors perceived by PROANTAR participants. A sample of 38 people, separated into two groups, was evaluated at the beginning and end of an expedition. The results obtained through questionnaires and interviews indicated the prevalence of environmental (60.71%), occupational (23.80%) and interpersonal (15.47%) stressors at the beginning, and interpersonal (55.97%), environmental (32.08%) and occupational (11.94%) stressors at the end. The results suggest that the forced coexistence generates the perception of interpersonal stressors overlapping environmental ones. Psychological phenomena should be considered in the planning of future expeditions, as they are related to health and performance of activities.

title: State of the art in vulvar cancer imaging

description: Abstract Vulvar carcinoma is an uncommon tumor that predominantly affects postmenopausal women. Currently, there is no screening procedure for vulvar carcinoma; in most cases, it is diagnosed only when symptoms appear. The most widely used staging system is that developed by the International Federation of Gynecology and Obstetrics. Lymph node status is the most important prognostic factor. We searched the PubMed/Medline database to identify relevant English-language articles on vulvar cancer, with a special focus on its imaging evaluation. Magnetic resonance imaging is useful for local and nodal staging, as well as facilitating the planning of surgical interventions and radiotherapy. Computed tomography or positron-emission tomography/computed tomography can play an important role in nodal and distant disease assessment, whereas ultrasound is often used for image-guided biopsies. Imaging is pivotal for staging and treatment planning in vulvar carcinoma.

title: Photochemical Synthesis of Ag and Au Nanoparticles Using a Thioxanthone Substituted Chitosan as Simultaneous Photoinitiator and Stabilizer

description: Silver (AgNPs) and gold (AuNPs) nanoparticles in aqueous solution were generated and stabilized using the 10-oxo-10H-dibenzene thiopyran-3-4-dicarboximide chitosan (TXICh) macrophotoinitiator. The photoinitiator and the nanoparticles in aqueous solution were characterized by UV-Vis spectroscopy and transmission electron microscopy (TEM). Pure TXICh in aqueous solution forms self-assembled particles with diameter around 30 nm. AgNPs were prepared using TXICh in the presence and absence of triethanolamine (TEOH). During irradiation, a broad band in the range of 410-415 nm was observed, corresponding to the plasmon absorption, indicating the AgNPs formation. TEM images revealed that the AgNPs had spherical shape in the absence and presence of TEOH. The synthesis of AgNPs in the presence of TEOH occurred rapidly (maximum conversion reached after 15 min), whereas in its absence 4 hours were required. The AgNPs prepared with TXICh/TEOH presented smaller and more uniform nanoparticles size. AuNPs were also prepared using TXICh as photoinitiator/stabilizer system. These nanoparticles showed an intense surface plasmon band at 530 nm and the TEM images revealed spherical particles of around 4 nm. These studies indicate that TXICh can act not only as a photoinitiator, but also as a stabilizer in the AgNPs and AuNPs formation.

title: Proposal of an Analytical Iterative Approach for the Simple Harmonic Oscillator

description: Abstract In this work we propose an analytical iterative approach in which the temporal evolution was replaced by the number of iterations. And for the case of a mass-spring system we obtained its velocity and its position as a function of time as partial sums of series that converged to the trigonometric functions that are the solutions of the simple harmonic oscillator.

title: Nutritive value of xaraés palisade grass in three light intensities

description: ABSTRACT This study aimed to evaluate the nutritive value and shear strength of the Xaraés grass (Urochloa brizantha) under the three intensities of light and four cuts. The experiment was conducted at FMVZ - UNESP, Botucatu, with a randomized block design, with the following treatments: natural luminosity, 30% and 60% light reduction, with four cuts and three replications. The analyzes were bromatological composition, digestibility, and shearing strength. There was no difference in digestibility between the treatments in any of the cuts, forage quality was influenced by the light intensity levels, and the treatment with 60% of light reduction produced higher concentrations of crude protein and ash, lower levels of neutral detergent fiber, hemicellulose, cellulose and shear strength. According to the studied cuts, the first one had the lowest cut interval and produced superior forage compared with the last one, as it obtained lower fiber content in acid detergent, lignin, hemicellulose, cellulose and consequent lower shear force. Therefore, the reduction of 60% of luminosity is beneficial to the quality and shear force of the Xaraés palisade grass.

title: Effect of LCORL gene polymorphism on body size traits in horse populations

description: ABSTRACT. The aim of this study was to determine polymorphism of LCORL gene in horse breeds and its association with body size. PCR-RFLP technique was performed using AluI for genotyping of 306 horses. Results showed that C is the rare allele in Iranian Breeds, because these horses have been used since ancient times as a courier and for war and archery, hence selection has done to benefit of spiky horses with medium body that need less food and are tireless. While, for foreign breeds; frequency of C allele was high that can be concluded these breeds used in fields, forests, and mines. A UPGMA dendrogram based on the Nei's standard genetic distance among studied breeds showed separate clusters for Iranian native and exotic breeds. Statistical association analysis of three observed genotypes with body size showed that there is an association between this polymorphism and body size criteria (p &lt; 0.01). Overall, it can be concluded that studied mutation in LCORL gene can be used as candidate marker for improving body weight in horse.

title: Reasons for Retirement and Retirement Satisfaction

description: Abstract This study aims to verify the validity of the retirement satisfaction inventory (RSI) for Brazilians and its invariance with regard to gender, age, education, marital status, income and region of the country, and to investigate whether the reasons for retirement influence a person's retirement satisfaction. At total of 1,002 retirees participated in the study, including both men and women ranging in age from 44 to 88. The analyses indicated RSI being subdivided into two scales: i) the scale of satisfaction with retirement, and (ii) the reasons for retirement with good psychometric characteristics. The latter was found to be a predictor of the former. The instruments were structured differently than in other countries, but they were shown to be applicable in the Brazilian context, especially with regard to assessing interventions such as retirement preparation programs.

title: Comparison of Volatile Profile and Antioxidant Activity of Piper divaricatum G. Meyer (Piperaceae) Using Cuttings and Cell Tissue

description: In this study, P. divaricatum (Piperaceae) plants were subcultured by cuttings and cell tissue in order to carry out a comparison of the volatile profile, phenolic compounds, and antioxidant activity. Propagation by cuttings used vermiculite substrate and Murashige-Skoog (MS) medium in the absence of growth regulators and rooting started at 15 days of growth providing a higher number of plants after 90 days. In vitro propagation was performed using shoot apices as explants in MS media supplemented with 0.5 mg mL-1 BA (6-benzyladenine). Volatile profiles analyzed by gas chromatography-mass spectrometry (GC-MS) showed as main compounds methyl eugenol, E-β-ocimene, and β-elemene in the in vivo and in vitro cultures. Phenolic contents determined by the Folin-Ciocalteu method had no significant difference at the end of 90 days of growth displaying a good linear correlation with antioxidant activity and phenylpropanoids amounts (r &gt; 0.7). However, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging was higher for in vitro plants grown in comparison to in vivo plants cultured.

title: A Self-Assembled AMF-Responsive Nanoplatform Based on Pillar[5]arene and Superparamagnetic Nanoparticles for Controlled Release of Doxorubicin

description: An alternating magnetic field (AMF)-stimuli responsive nanodevice based on magnetic nanoparticles (MNP) functionalized with water-soluble carboxylate-substituted pillar[5]arene (CP[5]A), namely MNP-CP[5]A, as a multiplatform for cancer treatment has been designed. MNP-CP[5]A was loaded with doxorubicin (DOX), showing a loading capacity of 9.5 mg g-1. The nanodevice demonstrated good colloidal stability, superparamagnetic behavior, and was capable to generate detectable heat in solution induced by AMF application. DOX release, monitored by ultraviolet-visible (UV-Vis) spectroscopy, was investigated by varying the temperature (37 and 45 °C) without AMF and in the presence of AMF (frequency (f) = 307 kHz, field amplitude (H) = 200 Oe, 45 °C) at pH = 7.4. Thermo-induced DOX release without AMF was 1.9% (1.8 μg mL-1) and 2.3% (3.3 μg mL-1) at 37, and 45 °C within 50 min, respectively. In an AMF DOX release increased to 5.7% (8.2 μg mL-1) within 50 min. Therefore, MNP-CP[5]A-DOX works as a chemo-hyperthermia nanodevice.

title: The association between genetic polymorphism of glutathione peroxidase 1 (rs1050450) and keratoconus in a Turkish population

description: ABSTRACT Purpose: To investigate the potential associations between keratoconus and catalase rs1001179, superoxide dismutase 2 rs4880, and glutathione peroxidase 1 rs1050450 gene polymorphisms in a Turkish population. Methods: The study group included 121 unrelated keratoconus patients and 94 unrelated healthy controls. Blood samples (200 ml) were collected from all patients and controls to isolate genomic DNA. Genotyping was performed to identify rs1001179, rs4880, and rs1050450 using real-time polymerase chain reaction (PCR). Genotype and allele frequencies were calculated; their associations with keratoconus risk were assayed, and the association with keratoconus risk and demographic factors was examined. Results: Glutathione peroxidase 1 rs1050450 polymorphism was present in 41% cases compared with 29% controls (OR=1.66; 95% CI=1.11-2.50; p=0.014). No association was observed between catalase rs1001179 and SOD2 rs4880 polymorphisms and keratoconus (for all, p&gt;0.05). Conclusions: This study evaluated possible relationships between rs1050450, rs1001179, and rs4880 polymorphisms and keratoconus susceptibility. We found a possible association between glutathione peroxidase 1 rs1050450 polymorphism and an increased risk of keratoconus. However, the genotype and allele frequencies were identical in the catalase rs1001179 and superoxide dismutase 2 rs4880 polymorphisms. Further studies are needed to analyze the effect of such variations in identifying keratoconus susceptibility.
