title: UnB's planning center: historical aspects, structural pathology mapping and intervention proposals

description: Abstract Durability is the ability of the structure to remain in full conditions of utilization, without presenting showing damage that could compromise partly or totally the use for which it was designed. The construction of SG-10 was based on precast walls in form of "U" and coverage of precast prestressed beams. Since its construction has no record of interventions that have been undertaken in order to prolong its service life. Based on this context, and knowing that the set of General Departments pavilions comprises representative buildings of UnB, this article aimed to assess the condition of the SG-10 concrete structure and map the deterioration levels of the elements and present intervention proposals. As an evaluation method was used the Inspections Guide that includes the GDE/UnB methodology as a basis for quantifying damage. After applying the methodology, it was found that the building needs to undergo an intervention process immediately, once recovery services need to be performed.

title: Evaluating the Electrochemical Characteristics of Babassu Coconut Mesocarp Ethanol Produced to Be Used in Fuel Cells

description: The aim of the present study is to assess the potential of ethanol deriving from the mesocarp of babassu coconut to be used in fuel cells. Babassu ethanol was generated through hydrolysis and fermentation processes. The Pt, PtRh and PtRu electrodes were prepared in carbon Vulcan XC72R through the reduction method and applied as electrocatalysts in ethanol oxidation reaction. X-Ray diffraction (XRD), energy-dispersive X-ray (EDX), stripping CO, cyclic voltammetry, chronoamperometry, and online differential electrochemical mass spectrometry (DEMS) were used to characterize the synthesized eletrocatalysts. The electrocatalyst Pt80Ru20/C presented larger active area and higher catalytic activity than other studied materials. The current efficiency of CO2 production rated less than 1% in all studied electrocatalysts, thus showing that babassu ethanol oxidation produces less pollutants than the commercial ethanol.

title: Electrode Material Containing Graphite Incorporated to an Amino-Functionalized Polydimethylsiloxane Network for the Detection of Copper

description: Graphite was incorporated to a polydimethylsiloxane (PDMS) polymer network functionalized with amino groups to obtain an electrode material and used to detect copper ions in aqueous solutions and sugarcane spirit. The polymer network was prepared with PDMS, 3-aminopropyl-trimethoxysilane (APTMS), tetraethyl orthosilicate (TEOS) with addition of graphite to obtain the electrode material. The materials were prepared with different mass concentrations of PDMS: 0, 3, 6, 12 and 18%; and characterized by thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). Quasi-reversible behavior was found when studying the [Fe(CN)6]3-/4- redox probe and were electrochemically stable up to 100 consecutive cycles. Electrochemical impedance measurements showed a second time constant at high frequencies for the PDMS electrodes, indicating a second phase in the polymer network with resistive properties, probably due to an increase in the material polymerization resistance. Square wave voltammetry studies were conducted with these electrodes to detect copper(II) ions in aqueous solution. The electrode proposed was applied to determine Cu2+ in a real sample, sugarcane spirit. The PDMS electrodes prepared here presented a potential to be applied as electrochemical sensors for detecting copper ions.

title: Acute effects of strength exercise with blood flow restriction on vascular function of young healthy males

description: Abstract Background Strength training with blood flow restriction (STBFR) provokes similar neuromuscular adaptations to traditional strength training using low training loads. However, there is a need for better understanding of the repercussions for antioxidant parameters and vascular function. Objectives: The objective of the present study was to investigate the effects of a session of low intensity strength training with blood flow restriction, compared with high intensity and low intensity strength training without blood flow restriction, on the levels of nitric oxide products and antioxidant enzyme activity in healthy young men. Methods: Eleven young men performed three strength exercise sessions: low intensity with blood flow restriction (LIBFR), high intensity (HI), and low intensity (LI). Activity of the antioxidant enzymes catalase (CAT) and superoxide dismutase (SOD) was assessed and metabolites of nitric oxide (NOx) were assayed before and after each session. Results: There were no changes to NOx plasma levels under the different exercise conditions (p &gt; 0.05). However, SOD activity exhibited a significant reduction after the LIBFR condition (p &lt; 0.05), while CAT activity reduced significantly after the LI condition (p &lt; 0.05). Conclusions: The results of this study suggest that one session of low intensity strength training with blood flow restriction does not reduce bioavailability of nitric oxide or induce redox imbalance in healthy young men.

title: Applicability of a Voltammetric Assay Based on the Electroreduction of Oxygen to Evaluate the Antioxidant Capacity of Pequi (Caryocar brasiliense Camb.) Pulp

description: This study aimed to use a differential pulse voltammetric (DPV) assay, based on the electroreduction of oxygen, to evaluate the antioxidant capacity of pequi pulp. The results were expressed in coefficient of antioxidant capacity (K), at different pH values and in trolox equivalent antioxidant capacity (TEAC), and were compared to the 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) spectrophotometric assays. The principal component analysis showed higher K for pequi pulp extract and pH tending to 7.15. The antioxidant capacity was related to the presence of gallic acid in its composition. Regarding the TEAC value, the best result was obtained by the DPV test (53.43 ± 5.14 µmol trolox g-1 pulp). The pequi pulp showed antioxidant capacity, compared to the standard antioxidant compounds evaluated. It was concluded that the voltammetric protocol was efficient to assess the total antioxidant capacity of pequi pulp and can be an alternative to conventional spectrophotometric assays, for the analysis of food matrices.

title: Effect of taping as treatment to reduce breast cancer lymphedema: literature review

description: Abstract Lymphedema is the most common complication during the postoperative period after surgery for breast cancer and can have a direct impact on daily activities. The objective of this study was to review the use of taping as an alternative/complementary treatment to reduce lymphedema. A literature review was conducted of scientific articles indexed on the PubMed, LILACS, MEDLINE, and PEDro databases and Google Scholar, and nine articles were selected. It was found that taping is a complementary therapy for reducing lymphedema, which may be used as an alternative treatment method, but cannot substitute multilayer compression therapy.

title: Is the weekly sets volume training performed by trained subjects in accordance with training recommendations guidelines for muscle hypertrophy?

description: Abstract AIM the aim of this study was to analyze the weekly sets volume (WSV) performed by trained men and women for each muscle group in muscle hypertrophy programs. METHODS One hundred and five resistance training practitioners of both sex (42 women, 29.8±5.7 years; 63 men, 28.5±5.7 years) consented to the analysis of their current training programs. Their training plains were analyzed by a researcher that used the following equation to determine the WSV performed for each muscle group: "number of exercises per muscle group per training session X number of sets per exercise in each training session X weekly training frequency per muscle group". The median values by each muscle group were compared within and between genders. RESULTS Between group analysis demonstrated that men performed higher WSV for upper body (UB) muscles than women (47.2±14,6 vs. 18.2±7.4 sets). Conversely, women performed a higher WSV for lower body (LB) muscle groups than men (23.8±11.2 vs. 11.5±7.0 sets). The training volume for the abdominal muscles did not differ between groups. When comparing the WSV for the UB, LB and core musculature within groups, men perform higher training volumes for the UB compared to the LB and core, while women train the LB with a higher volume compared to the other musculature. CONCLUSION For some muscle groups, the WSV is higher than recommended in the literature for muscle hypertrophy. Men emphasize the UB training, while women emphasize training the LB. Moreover, the WSV performed by subjects of both genders is disproportionate between different muscle groups.

title: Removal of Beta-Lactams Antibiotics through Zero-Valent Copper Nanoparticles

description: The removal of the beta-lactam antibiotics (ceftriaxone and cefadroxil) through zero-valent copper nanoparticle (nZVC) was studied in this work. Excellent removal degrees (&gt; 85%) were obtained for both analytes in only 20 min of reaction. Studies were performed in both oxic and anoxic conditions, and in the presence of t-butyl alcohol (TBA), an inhibitor of radicals. The results did not show significant changes. Therefore, the hydroxyl radicals are not the main species responsible for the removal. Total organic carbon cefadroxil analysis indicated a removal of 57% after 180 min of reaction. Studies involving Cu+ indicated that probably these are the principal species responsible for the removal of antibiotics. Kinetic studies have shown that two-phase reaction occurred in the antibiotics removal process and both phases followed pseudo-first order kinetic model. The first mechanism is related to the antibiotics degradation by Cu+ species and the second mechanism is related to the antibiotics adsorption by hydroxides/oxides of Cu2+ species.

title: MARX, FREUD AND THE GODS BLACK PEOPLE MAKE: EUROPEAN SOCIAL THEORY AND THE REAL LIFE FETISH

description: Since the early-modern encounter between African and European merchants on the Guinea Coast, the term “fetish” has analogized alleged disorders in European thought to African gods. Yet African gods have a logic of their own that is no less reasonable, given the position of their worshipers in the Atlantic economy, than are the different but equally socially positioned theories of Marx and Freud. This lecture offers a novel perspective on the social roots of these tandem African and European understandings of collective action, illuminating the relationship of European social theory to the racism suffered by Africans and assimilated Jews alike.

title: Full Factorial Experimental Design for Carbamazepine Removal Using Electrochemical Process: a Case Study of Scheming the Pathway Degradation

description: Carbamazepine is an antiepileptic drug which is considered one of the persistent compounds detected in Malaysian aquatic environment. In this present study, a full factorial experimental design was applied for the analysis of effect NaCl amount, initial concentration of carbamazepine, applied voltage and treatment time on the electrochemical removal percentage of carbamazepine. However, applied voltage was found as the most significant factor with p = 0.00 lower than 95% confidence level. The investigation of effect NaCl and Na2SO4 on the pathway degradation for carbamazepine was provided using liquid chromatography-time of flight/mass spectrometry (LC-TOF/MS). The results showed that new by-products were identified such chloro-epoxy carbamazepine, and other by-products, were detected in the presence of NaCl and Na2SO4 electrolytes. High inhibition percentage of Escherichia coli (E. coli) bacteria was observed at 24.0 h incubation time for both NaCl and Na2SO4 electrolytes after 80 and 20 min of treatment, respectively.

title: The implementation of work environment surveillance by the Brazilian Unified Health System (SUS): the experience of the State Reference Center for Worker’s Health (Cesat) in Bahia

description: Abstract Objective: to describe and characterize the actions and results of the work environments’ surveillance actions developed by the Centro Estadual de Referência em Saúde do Trabalhador - Cesat (State Reference Center for Worker’s Health). Methods: descriptive study using technical documents generated by the surveillance inspections developed in work environments by the Cesat in the state of Bahia, Brazil, from 2004 to 2013. Results: we analyzed 283 surveillance reports carried out in 211 companies from 25 branches of economic activities, most of them private chemical and petrochemical industries. The Public Prosecutor’s Office demanded the majority of the actions. The main reasons for the inspections were mapping risks and verifying compliance with control recommendations. We identified a processual character of the actions, that is, they are continuous and systematic, as well as intersectoral and interdisciplinary approaches, besides workers’ participation. The inspections effectiveness was evidenced by the total ou partial compliance with the recommendations. Conclusions: Cesat has been well playing its role of structuring workers’ health surveillance actions in the state of Bahia. Our findings indicate that its performance can contribute to the evaluation and consolidation of SUS’ (Brazilian Unified Health System) work environment surveillance.
