title: EVALUATION OF POTENTIALLY TOXIC METALS IN LEACHES FROM SOLID WASTE DEPOSITION AREA IN BELÉM-PARÁ

description: The formation of solid waste is a global challenge regarding environmental preservation. Due to the lifestyle of modern society, which aims to improve practicality, new products are constantly being released in the market and increasing the formation of waste. The decomposition of waste from various origins produces a dark liquid named leachate, which presents high rates of organic and inorganic compounds. The objective of this study was to assess the concentration of potentially toxic metals in the leachate collected from the Aurá dump. The concentrations of Cd, Cu, Cr, Mn, Ni, Pb, and Zn were evaluated in leachate samples collected in a period of a year, covering two typical seasonal periods of the Amazon region with more and less rainfall. The leachate samples collected in the Aurá dump were determined in the Toxicology Laboratory of Instituto Evandro Chagas (IEC), by means of Plasma/Inductively Coupled Optical Emission Spectrometry (ICP-OES). The Cr, Mn, and Pb metals analyzed in the slurry samples are in a concentration above the maximum limits specified by CONAMA Resolution No. 430/2011, causing significant environmental concerns.

title: Influenza pandemics throughout Brazilian history

description: Abstract Brazil has experienced several major epidemics of influenza, and the most destructive was in 1918-1919. This article focuses on mortality, mitigation policies, and the consequences of pandemic influenza during the national period. We provide the first mortality estimates for the 1890-1894 influenza pandemic and correct figures for later epidemics. The 1918-1919 episode cost more lives than assumed, although some cities suffered less, possibly because of public health actions. Influenza caused pandemics in 1957, 1968, 1976, and 2009, but these did not cause unusual outbreaks in Brazil.

title: Ultra-refined yerba mate ( Ilex paraguariensis St. Hil) as a potential naturally colored food ingredient

description: ABSTRACT Ultra-refined yerba mate (URYM), with a final particle size of 5 to 12 microns, is an innovation in the market that aims to diversify and increase the consumption of yerba mate ( Ilex paraguariensis St. Hil) through its practicality and versatility of preparation. The present work seeks to evaluate the potential for applying naturally colored URYM in food products. The nature of this study was exploratory, adopting a chemical approach (analysis of the antioxidant potential); physical approach (color stability) and sensory perception. URYM is a suitable naturally colored food ingredient with natural antioxidant appeal. Methanolic extraction of URYM (MEUR) was more efficient in scavenging DPPH radicals compared with aqueous extract of URYM (AEUR) (959.5 vs . 638.1 µmol Trolox g–1). No differences were found between AEUR and MEUR for total phenolic content in mg GAE g–1 (266.4 and 339.0, respectively) and scavenging of ABTS radicals in µmol Trolox g–1 (1008.9 and 1053.8, respectively). Water was able to extract phenolic compounds with antioxidant activity. Ice cream, juice, cake, and cookies emerged as the food products in which consumers used URYM in their homemade foods. With good color stability (no difference between L*, a* and b* parameters during the six-day) and good acceptance, cake with URYM added has a profile described as tasty, sweet, soft, and mate flavor. The results also demonstrated consumer interest in food products and ingredients with a healthy appeal.

title: Album/Report by the Pequenas Irmãs da Divina Providência: records of social and medical assistance in the coal-producing region of southern Santa Catarina, 1955-1957

description: Abstract During the first half of the twentieth century, the coal-producing region of Santa Catarina state underwent intense industrialization that directly impacted various ways of life; various health problems emerged in the region as a result of coal mining and impeded economic progress. As the government was unable to meet health demands, local businesses established partnerships with female religious orders that provided assistance services in the villages where workers lived. As part of such a partnership, the Pequenas Irmãs da Divina Providência created an album of texts, drawings, and photographs as a report describing their activities from 1955 to 1957 in one such village in the region.

title: Objective meaning fixation: organizational cognitive processes under uncertainty and conflict

description: Abstract This essay concerns the fixation of objective meaning in high-discretion decisions and actions under uncertainty and conflict. It collects and develops arguments in the literature, to show how this fixation happens. The approach to concept development was a pragmatic and integrative literature review on strategic decision-making. There are two kinds of objective meanings. The general objective meaning of strategic action consists of the mission and systemic objectives set by the organization’s dominant coalition. Under conflict and uncertainty, guided by the general objective meaning, organizational cognitive processes identify and analyze uncertainties, manage conflict, and set the specific objective meaning. Such processes are immanent in the development of and choice among alternatives. These concepts - organizational cognitive processes, necessary social relationships to organization, and specific objective meaning - and their causal articulation are the main contribution of this piece. Organizational pragmatism prevails as well as an interpretation that fixates objective meanings.

title: THE CASCADING EFFECT OF STATIC AND DYNAMIC MARKETING CAPABILITIES ON THE INTERNATIONAL PERFORMANCE: ANALYZING MARKET ORIENTATION AS AN ANTECEDENT

description: ABSTRACT This investigation analyzes the relationships between static marketing capabilities (SMC), dynamic marketing capabilities (DMC), and business-to-business (B2B) small and medium-sized enterprises’ (SME) international performance, and the interconnection between SMC and DMC. We also analyze the role of market orientation (MO) as an antecedent of marketing capabilities. A quantitative study was developed using a survey-based method. We collected 335 valid responses from internationalized Portuguese B2B SMEs. Structural equation modeling was used to test the proposed hypotheses. Results show a direct and positive relationship between SMC and international performance. DMC was positively linked with SMC, thus indirectly exerting its influence on international performance. Also, a positive relationship between MO and both marketing capabilities was observed, revealing its antecedent nature over marketing capabilities. This study contributes to marketing capabilities research, given that interrelationships between different types of marketing capabilities were never studied before. Furthermore, it draws managers’ attention to the importance of developing basic marketing-mix capabilities since they appear as the direct link to international performance.

title: Defibrillation Threshold Testing and Long-term Follow-up in Chagas Disease

description: Abstract Background Sudden cardiac death is the most common cause of death in chronic Chagas cardiomyopathy (CCC). Because most CCC patients who are candidates for implantable cardioverter-defibrillators (ICD) meet criteria for high defibrillation threshold values, a defibrillator threshold test (DTT) is suggested. Objectives We investigated the use of DTT in CCC patients, focusing on deaths related to ICD and arrhythmic events, as well as treatment during long-term follow-up. Methods We retrospectively evaluated 133 CCC patients who received an ICD mainly for secondary prevention. Demographic, clinical, laboratory data, Rassi score, and DTT data were collected, with p &lt; 0.05 considered significant. Results The mean patient age was 61 (SD, 13) years and 72% were men. The baseline left ventricular ejection fraction was 40 (SD, 15%) and the mean Rassi score was 10 (SD, 4). No deaths occurred during DTT and no ICD failures were documented. There was a relationship between higher baseline Rassi scores and higher DTT scores (ANOVA = 0.007). The mean time to first shock was 474 (SD, 628) days, although shock was only necessary for 28 (35%) patients with ventricular tachycardia, since most cases resolved spontaneously or through antitachycardia pacing. After a mean clinical follow-up of 1728 (SD, 1189) days, 43 deaths occurred, mainly related to progressive heart failure and sepsis. Conclusions A routine DTT may not be necessary for CCC patients who receive an ICD for secondary prevention. High DTT values seem to be unusual and may be related to high Rassi scores.

title: Looting the file, hearing yourself in the echo: The voracious reading of the European archive in the poetry of Rubén Darío

description: Abstract When reading Latin American literature from the autobiographical genre, Sylvia Molloy proposes that its appropriation of European culture takes place through the voracious looting of its archive. Pursuing this Argentinean author’s ideas, this article seeks to offer a reading of this voracious procedure in the work of Nicaraguan poet Rubén Darío, focusing particularly on one of his poems, “Caracol”, in dialogue with other of his poems, as well as comparing it with works by Julián del Casal, a contemporary Cuban poet with whom Darío shared a common interest in modern French culture. From the reading of these poems, we intend to show how the use of the European tradition prompts an encounter with our own literature, in which the irreverence in the use of the archive imposes itself on the copy.

title: Consumption of nutritional supplements by teenagers attending gyms supplements and exercise in teenagers

description: ABSTRACT Objective: To describe the supplements used by adolescents in gyms in the city of São Paulo and the factors related to their use. Methods: Participants were 1,012 adolescents of both sexes, aged between 13 and 18 years old, all of them regular regulars at gyms in the city of São Paulo. For data collection, a questionnaire was used to identify the main supplements consumed by adolescents. The chi-square test was used to verify possible associations with a significance of p&lt;0.05. Results: The use of supplements was more frequent in the age group between 16 and 18 years, in the socioeconomic level B, and the use of these supplements was higher as the time of exercise in the gym was longer (&gt;12 months). The amount of exercise modalities practiced in the gym was inversely associated with the use of supplements. Male adolescents consumed significantly more supplements than females, and Physical Education professionals, friends and parents were the ones who most influenced adolescents to use supplements. The main supplements used by the boys were carbohydrate gel (90.9%) and hypercaloric (94.5%). In girls it was fat burner (55.0%) and vitamins and minerals (50.0%). Conclusion: The use of supplements was common among adolescents who exercise in gyms in São Paulo and the indication was made by physical education professional.
