A insurgência estudantil paranaense no pensamento militar: uma análise da Operação Pente Fino no contexto ditatorial de 1968
Authors: Dos Santos Paula Eloise , Souza de Jesus Lucas Augusto 
Published: March 2021

Esse artigo visa apresentar uma análise documental da Operação Pente Fino, realizada na Delegacia Regional do Paraná e Santa Catarina, na cidade de Curitiba, cujo intuito foi prender as lideranças do Movimento Estudantil paranaense sob acusação de subversão, denotando o aumento da repressão policial às manifestações estudantis. Para essa análise nos valemos do conceito de região, entendido como lugar de conflito e de relações de poder. A presença da repressão evidencia que a população paranaense não era exclusivamente “ordeira e conservadora” conforme a construção de sua imagem por parte do Estado. Palavras-chave: Movimento Estudantil paranaense; Regime Militar; Repressão. Abstract This paper aims to present a documental analysis of the "Pente Fino" operation, carried out in Paraná and Santa Catarina Regional Police Station, in Curitiba city. This operation had a purpose to arrest the leaders of the Paraná Student Movement, accused of subversion, denoting the increase of the police repression in student protests. For this analysis, we use the concept of region, understood as a place of conflict and power relations. The presence of repression testifies that the population of Paraná was not exclusively “orderly and conservative”, according to the state's construction of its image.Keywords: Paraná Student Movement; Military Regime; Repression.

O presente artigo apresenta as principais contradições do projeto político nacional da Frelimo, em sua tentativa de construção de uma consciência nacional no pós-independência em Moçambique. É possível identificar alguns aspectos que interagiam e moldaram a memória coletiva do povo moçambicano com relação à guerra civil, como no romance Ventos do Apocalipse de Paulina Chiziane, onde a autora enuncia, de forma crítica ao governo socialista e unipartidarista em Moçambique, uma narrativa literária que pode ser analisada como fonte histórica.Palavras-chaves: Moçambique. Nacionalismo. Guerra civil. Literatura.Abstract This paper presents the main contradictions of Frelimo's national political project, in its attempt to build a national consciousness post-independence in Mozambique. It is possible to identify some aspects that interacted and shaped the collective memory of the Mozambican people in relation to the civil war, as in the novel Ventos do Apocalipse by Paulina Chiziane, where the author critically enunciates the socialist and unipartisan government in Mozambique, a literary narrative that can be analyzed as a historical source.

Differences in Metacognitive Skills among Undergraduate Students in Education, Psychology, and Medicine
Authors: Gutierrez de Blume Antonio P. , Montoya Londoño Diana Marcela 
Published: March 2021

Metacognitive skills such as when and why to apply strategies successfully given task demands (conditional knowledge) and those that assist in regulation like comprehension monitoring are essential for effective learning. However, the debate regarding whether metacognitive skills are domain general or domain specific continues to rage among scholars.Presumably, if metacognitive skills are domain specific, there should be significant differences between domains whereas if they are domain general, there should be no differences across domains. Thus, in the present study we examined the generality/specificity of metacognitive skills (knowledge of cognition: declarative, procedural, and conditional; regulation of cognition: planning, information management, debugging, comprehension monitoring, and evaluation) in a sample of Colombian university students (N = 507) studying education (N = 156), psychology (N = 166), and medicine (N = 185) employing the Spanish version of the Metacognitive Awareness Inventory. Results revealed that there were significant differences in all but two metacognitive skills (procedural knowledge and debugging) across domains, largely supporting the domain specific hypothesis, but also partially supporting the domain general view. Implications and recommendation of the findings for theory, research, and practice are discussed.

Influence of metabolites of microorganisms from permafrost on the synthesis cytokines by human peripheral blood mononuclear cells in vitro
Authors: Kolyvanova S. S. , Kalenova L. F. 
Published: March 2021

Permafrost is a unique ecosystem characterized by consistently negative temperatures. It has been shown that microorganisms can be there in a state of hypometabolism or anabiosis during geological time. It is known that microorganisms occupy a wide habitat due to the presence of multifunctional systems of adaptation and communication. One of the manifestations of these systems is the production of secondary metabolites (MBs), which include signaling molecules that do not have strict species specificity. The biological activity of signaling molecules largely depends on the number of bacterial cells and the temperature of their cultivation.In this work we used secondary MBs of Bacillus sp. from Permafrost obtained at different temperatures of microorganism cultivation (at -5 °C – “cold” MBs and at 37 °C – “warm” MBs) in doses of 0,05 × 106 (small dose) of microbial cells (m.cl.) in ml of saline or 500 × 106 (high dose) m.cl./ml. The influence of MB of Bacillus sp. for the TNFα, IL-1β, IL-8, IL-2, IFNγ, IL-4 and IL-10 production by human peripheral blood mononuclear cells (MNC) in supernatants of 24-hour cell cultures was estimated by ELISA whith using the “VectorBEST” test system (Russia) on a LUCY-2 (ANTHOS) spectrophotometer (Austria).It was found that the activity of synthesis by human MNC of the main spectrum of cytokines significantly increased (p < 0.01 for all indicators) under the influence of MB Bacillus sp. regardless of the temperature of their cultivation and the dose of bacteria. The exception was IL-8, the level of which under the influence of a high dose of “warm” MBs didn’t differ from the control. Compared to PHA the cytokines synthesis by MNC depended on the dose and the temperature of obtaining of MBs. Thus, under the influence of “warm” MBs the level of TNFα was significantly lower than its level under the influence of PHA regardless of the dose. Regardless of the temperature of obtaining metabolites the level of IL-8 under the influence of metabolites from a dose of 500 × 106 m.cl. was reduced relative to the PHA group. Comparison of the influence of “warm” and “cold” MBs of Bacillus sp. showed that small doses of “cold” metabolites to a greater extent stimulate the synthesis of pro-inflammatory cytokines (TNFα, IL-1β, IL-8, IFNγ). High doses of “heat” metabolites of Bacillus sp. to a greater extent they activate human MNCs for the synthesis of anti-inflammatory cytokines (IL- 4 and IL-10). Considering that TNFα, IL-1β and IL-10 are cytokines of systemic action and are responsible not only for the activation of the immune system, but also for the mobilization of other regulatory systems of the organism, it can be assumed that the secondary metabolites of microorganisms from Permafrost will be efficient as a substrate for the development of new immunomodulators and adaptogens in the future.

A multicriteria model for assessing corporate sustainability in the construction industry
Authors: Bezerra Paloma R S , Schramm Fernando , Schramm Vanessa B 
Published: March 2021

Abstract
The construction industry is one of the most critical activities for the sustainable development of a country, generating positive and negative economic, social and environmental impacts. These aspects can be measured by Sustainability Indicators and Indices, which are useful tools for society, investors and the government in decision-making, especially when purchasing products and services, as they quantify information about a phenomenon in a given dimension of sustainability. Therefore, the objective of this study is to propose a model for assessing the sustainability of civil construction companies, considering economic, social, environmental and corporate governance criteria. These criteria are aggregated into a single index using the PROMETHEE II multicriteria method, which allows to avoid the compensation effect caused by the aggregation operators based on the additive model. The model was used to evaluate four Brazilian construction companies: Alpha, Beta, Delta and Gamma. The data of these companies were collected in a database of the Brazilian Chamber of the Construction Industry and in the sustainability`s reports published by them. We concluded that the companies Alpha and Gamma, followed by the company Beta presented the best performances in corporate sustainability, while the construction company Delta has the worst level of corporate sustainability.

Abstract
Purpose: The Nice knots have been widely used in orthopedic surgeries to fix torn soft tissue and fracture in recent years. The study aims to investigate the clinical efficacy and prognosis of intraoperative and postoperative Nice Knots-assisted reduction in the treatment of displaced comminuted clavicle fracture.Methods: From Jan 2014 to Dec 2019, 75 patients diagnosed with unilateral closed displaced comminuted clavicle fracture were treated with open reduction and internal fixation (ORIF) in this study. Nice knot group (the NK group) included 38 patients and the other 37 patients were in the traditional group (the TK group). The time of operation and the amount of bleeding during operation were recorded. Post-operative clinical outcomes and radiographic results were recorded and compared between these two groups. The Visual Analogue Scale (VAS), shoulder range of motion (ROM), Constant-Murley score and complications such as infection, nonunion, implant loosening, fragment displacement and hardware pain were observed in the two groups. Results: In the comparison between the two groups, there was no significant difference in age, sex, the cause of displaced clavicle fracture, and other basic information between the two groups. The operation time, intraoperative fluoroscopy time, and intraoperative blood loss were significantly reduced in the NK group (P < 0.01). There were 2 cases of plate fracture in the TK group. The follow-up results showed that there was no significant difference in VAS, ROM, and Constant-Murley scores between the two groups.Conclusion: The use of Nice knot, in comminuted and displaced clavicle fractures can reduce intraoperative blood loss, shorten operation time, facilitate intraoperative reduction, and achieve satisfactory postoperative clinical results. This study demonstrates that Nice knot is a simple, safe, practical and effective auxiliary reduction method.

Published: March 2021

Abstract
Aim: The aim of the study was to examine the crosss-ectional association between serum albumin and hyperuricemia (HU).Subjects and methods: HU was defined as uric acid ≥420 mol/L for the male population and ≥357 mol/L for the female population.We reviewed the files of 216 consecutive patients with Idiopathic membranous nephropathy treated at our hospital between 2010 and 2019.The correlation of serum albumin with hyperuricemia and the association between serum uric acid levels and the clinical of Idiopathic membranous nephropathy were assessed by statistical analysis.A multivariable logistic analysis model was applied to test the association after adjusting for a number of potential confounding factors.Results: Triglyceride and serum albumin were higher in group with hyperuricemia than in group without hyperuricemia(p=0.020, P<0.001 respectively). As serum albumin rose for 1 g/L the probability for hyperuricemia increased for 17 % (adjusted II OR= 1.17, 95%CI (1.02, 1.35), P = 0.0294). A unit increase in serum albumin was associated with increases of 6.64 umol/L in uric acid (adjusted II β = 6.64, P = 0.0135). Using Tertile 1(T1) for reference, Tertile 3 (T3) group was positively associated with both hyperuricemia (adjusted II OR=44.21, 95%CI(12.76, 75.67), P=0.0064) and uric acid (adjusted II β=98.64, P=0.0116). The interaction test showed signifcant interactions between serum albumin and BMI when hyperuricemia or uric acid were used to determine the outcomes. The participants BMI ≥25 kg/m2 had a higher OR between serum albumin and hyperuricemia and had a higher β between serum albumin and uric acid than BMI＜25kg/m2 (for hyperuricemia: OR =1.01 vs 1.18, P for interaction=0.0056; for uric acid: β =0.96 vs 6.23, P for interaction =0.0154). The area under the ROC curve (AUC) was 0.7615 in the participants BMI ≥25 kg/m2. The sensitivity and specifcity of this point were 47.37% and 95.83%,respectively.Conclusion: Our study showed that serum albumin was positively associated with hyperuricemia and uric acid, especially in obese subjects.
Fixed-Time Fuzzy Adaptive Fault-Tolerant Control for Hypersonic Flight Vehicles Using a New Prescribed Performance Function

Published: March 2021

Abstract
This article proposes a new fixed-time fuzzy adaptive fault-tolerant control methodology for the longitudinal dynamics of hypersonic flight vehicles (HFVs) in the presence of actuator faults, uncertain dynamics and external disturbances. In contrast with the conventional fixed-time control schemes that typically contain the fractional powers of errors in their designs, this work develops a low-complexity control structure in the sense of removing the dependence on the need of above-mentioned fractional power terms by means of prescribed performance control (PPC) method. Different from the most existing PPC approaches where the initial conditions of tracking errors are required to be known, the newly proposed prescribed performance function (PPF) can relax such restrictions through choosing properly small initial values of PPF. Fuzzy logic systems (FLSs) are employed to handle unknown dynamics and minimal learning parameter (MLP) technique is incorporated into the design for the purpose of alleviating computation burden. Closed-loop stability is rigorously proved via Lyapunov stability theory and simulation results are eventually given to validate the effectiveness of the proposed control strategy.
Transcriptomic analyses reveal molecular mechanisms underlying regulation of floral attributes in Lonicera japonica Thunb.
Authors: Shi Lei , Shen Yuan , Chi Yuhao 
Published: March 2021

Abstract
Background

Lonicera Japonica Thunb. is a perennial, semi-evergreen and twining vine in the family of Caprifoliaceae, which is widely cultivated in Asia. Thus far, L. japonica is often used to treat some human diseases including COVID-19, H1N1 influenza and hand-foot-and-mouth diseases, however, the regulatory mechanism of intrinsic physiological processes during different floral developmental stages of L. japonica remain largely unknown.
Results

The complete transcriptome of L. japonica was de novo-assembled and annotated, generating a total of 195850 unigenes, of which 84657 could be functionally annotated. 70 candidate genes involved in flowering transition were identified and the flowering regulatory network of five pathways was constructed in L. japonica. The mRNA transcripts of AGL24 and SOC1 exhibited a downward trend during flowering transition and followed by a gradual increase during the flower development. The transcripts of AP1 was only detected during the floral development, whereas the transcript level of FLC was high during the vegetative stages. The expression profiles of AGL24, SOC1, AP1 and FLC genes indicate that these key integrators might play the essential and evolutionarily conserved roles in control of flowering switch across the plant kingdom. We also identified 54 L. japonica genes encoding enzymes involved in terpenoid biosynthesis pathway. Most highly expressed genes centered on the MEP pathway, suggesting that this plastid pathway might represent the major pathway for terpenoid biosynthesis in L. japonica. In addition, 33 and 31 key genes encoding enzymes involved in the carotenogenesis and anthocyanin biosynthesis pathway were identified, respectively. PSY transcripts gradually increased during the flower development, supporting its role as the first rate-limiting enzyme in carotenoid skeleton production. The expression level of most anthocyanin biosynthetic genes was dramatically decreased during the flower developmental stages, consistent with the decline in the contents of anthocyanin.
Conclusion

These results identified a large number of potential key regulators controlling flowering time, flower color and floral scent formation in L. japonica, which improves our understanding of the molecular mechanisms underlying the flower traits and flower metabolism, as well as sets the groundwork for quality improvement and molecular breeding of L. japonica.
