title: Performance of blended concrete with supplementary cementitious materials under sulfuric acid - a systematic review

description: ABSTRACT Supplying sewerage systems in cities and factories has a high cost, both for design, execution, and maintenance. Reinforced concrete exposed to the aggressive acids produced by wastewater microorganisms receives high costly coatings to avoid corrosion and impairment of structural functions. Thus, this systematic review had two main goals: (1) to identify the supplementary cementitious materials (SCM) that improve concrete resistance to chemical sulfuric acid attack (H2SO4) and (2) to describe the performed tests to access concrete resistance to H2SO4 in laboratory conditions. After careful analysis of scientific references collected on indexed bases, the study showed that the test methods used to appraise samples resistance do not follow a standard protocol, hindering quantitative analysis between distinct studies results. In general, concrete resistance to H2SO4 is evaluated by immersing concrete samples in high concentrated acid solutions and assessing its compressive strength and mass change on a 28 or 30 days base sequence. Using SCMs improve resistance to sulfuric acid, and binders made with silica fume had the best results. This review may encourage the creation of test protocols to assess the resistance of concrete to H2SO4 that allow further statistical analysis of the research results.

title: Queremos! Case: challenges of a startup in the pandemic

description: Abstract Created in Rio de Janeiro in 2010, Queremos! came up with an innovative proposal to bring fans and artists together through a crowdfunding structure, which made it possible to perform shows in locations that normally would not be covered in the original tours. After repositioning the business model in 2013, the company abandoned the crowdfunding model that made it famous and focused on the production of live events. This enabled an expansion to the USA between 2013 and 2016 and gave the brand a strong presence in the main Brazilian capitals in the following years. However, after its best year in 2019, the company was surprised by the COVID-19 pandemic, which drastically affected the entertainment and live events sector in Brazil and worldwide. The case puts the readers in the role of the company’s partners in order to reflect on the strategic and operational challenges that Queremos! had to face from the prohibitions on live events due to the pandemic. The case is recommended for undergraduate and graduate students of administration and cultural production courses concerned with discussing topics and concepts related to the area of planning in times of uncertainty, risk analysis, management of changes, business modeling, and innovation in startups.

title: FATIGUE AND REHABILITATION IN THE TRAINING OF GYMNASTS

description: ABSTRACT Introduction Aerobic gymnastics requires a lot of physical ability and endurance. Fatigue is an inevitable consequence of intrinsic movements with a high intensity related to the sport. Objective Analyze the rehabilitation strategy of sports fatigue in aerobic gymnastics athletes caused by training. Methods 20 volunteer aerobics students in colleges and universities were recruited and divided into experimental and control groups. High-intensity aerobic gymnastics training was performed where the experimental group used a combined exercise fatigue recovery scheme, while the control group used only traditional walking and stretching. Results Lasting 40 minutes, the post-exercise fatigue rehabilitation protocol showed a decreasing trend in muscle stress, while the control group evidenced a fluctuating decreasing trend. The recovery frequency of the experimental group was higher than that of the control group. Conclusion The combined method of rehabilitation training mentioned in this paper can better regulate the heart rate of athletes, reduce the level of fatigue, and transform passive relaxation into active sports rehabilitation, engaging the enthusiasm of sport in athletes. Therefore, the scheme proposed in this paper has better practical significance and practical value. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

title: Governing by numbers: Organisation for Economic Co-Operation and Development’s policy for basic education

description: ABSTRACT This paper proposes to analyze the assumptions of the Learning Compass 2030 project of the Organisation for Economic Co-operation and Development, aimed at education, with a view to create an international school curriculum through the definition of competencies, knowledge, skills, common attitudes, and values. By using the compass metaphor as a methodological and ideological inspiration, it spreads the idea of curriculum flexibility, lifelong learning, learn to learn and autonomy, and anticipates the needs of students in their future life and work options. We argue that terms, vocabulary, conceptions, written language, and purposes inscribed in the Common National Curriculum Base - High School are aligned to corporate and mercantile interests, and also systematize a pragmatic, instrumental and functionalist character for Basic Education.

title: Racism in Childhood and the Childhood of Racism: Life and tracks of a Black Child

description: Abstract This article, based on an archaeological-type methodology of genealogy, aimed at retrieving and mapping fragments of the life of a black child in a judicial document housed at the Simonense Historical Museum in 1861. Further, it intends to understand this document, its speeches and positions, deciphering how the legal machinery worked in its most expressive concept of power-knowledge, and what views and approaches the local power used to manage lives and bodies. The work also sought to understand how, in that nineteenth-century context, “color” and “race” influenced procedural disentangling. The work led us to find that in the middle of the 19th century a new idea of ‘child’ came into being. This child model, idealized at that time by hygienist medicine, would only serve the white, Catholic, wealthy child. It would not support the black child. It was not just an existing type of racism, but a new type of racism that was born along with the very idea of a child. It was the childhood of this type of racism in Brazil. And this racism would have consequences for legal proceedings involving black children. It would give rise to selective justice, with judicial decisions affected by the racial issue.

title: Connected Education Innovation Program: a new national policy for the use of digital technologies in public schools in Amazon

description: ABSTRACT In this article, there is a contextualized analysis, through a critical approach, of Decree No. 9.204, of November 23, 2017, which instituted the Connected Education Innovation Program, the new Ministry of Education policy to replace the National Computer Program in Education, and its intertextuality, based on the legal normative framework initiated with the National Education Plan (2014-2024), considering the theoretical and methodological influences in the formulation of the cycle of national public policies for the use of digital technologies and their consequences on the education system in Amazonas. As a result, it was confirmed that only 4% of public schools in the state of Amazonas managed to adhere to Connected Education Innovation Program, while adherence as a regulatory mechanism of national policy proved to be excluding, and the goal of universal access to the internet in basic education public schools in Brazil until 2019 has not been achieved.

title: The Gasparian method as a critical perspective of didactic qualification in higher education: research-action

description: ABSTRACT This article criticized the reproductivist model of uncritical transmission of knowledge centered on the figure of the teacher and investigates the potential of the didactic teaching action, in higher education, when supported by the Gasparian method. This is a qualitative study of the action-research type and formative evaluation, elaborated under the voice of professors who co-participated in the intervention project. Data were treated by content analysis. Results showed professors’ engagement in relation to the method, a favorable climate for student learning, good adaptation, overcoming of difficulties, and commitment to the intervention. The didactic teaching action, based on the method, brought students closer to the political and social discussions and actions of everyday life, providing academic protagonism. It provided insights that dialectically challenged the situated social issues, indicating a propitious scenario for future implementation.

title: Vestibular recruitment: new application for an old concept

description: Abstract Introduction Vestibular recruitment is a sign of hyperexcitability of central vestibular neurons and may be characteristic of peripheral vestibular damage. Objective To define the post-caloric recruitment index and its ability to predict the stage of vestibular compensation and peripheral lesion. Methods First of all, we demonstrated that larger values in the cold post-caloric stimulation compared to warm stimulation were equivalent to vestibular recruitment observed during the sinusoidal harmonic acceleration test. In the next step, patients with vestibular complaints and asymptomatic controls were submitted to the caloric test. We calculated post-caloric recruitment index for the control group. Among the study group, we analyzed the relation between post-caloric recruitment and unilateral weakness as well as the types of vestibular diagnoses. Results Mean post-caloric recruitment was 17.06% and 33.37% among the control and study group, respectively. The ratio between post-caloric recruitment and unilateral weakness was 1.3 in the study group. Among recruiting subjects, no significant difference of unilateral weakness from the lesioned or healthy side was observed. We found no differences in vestibular diagnoses between recruiting and non-recruiting subjects. Conclusion Post-caloric recruitment index identified asymmetric vestibular tonus and central compensation. The normal value was established at 17.06%.

title: SARS-CoV-2 Punctuated Evolution

description: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) evolved slowly over the first year of the Coronavirus Disease 19 (COVID-19) pandemic with differential mutation rates across lineages. Here, we explore how this variation arose. Whether evolutionary change accumulated gradually within lineages or during viral lineage branching is unclear. Using phylogenetic regression models, we show that ~13% of SARS-CoV-2 genomic divergence up to May 2020 is attributable to lineage branching events (punctuated evolution). The net number of branching events along lineages predicts ~5% of the deviation from the strict molecular clock. We did not detect punctuated evolution in SARS-CoV-1, possibly due to the small sample size, and in sarbecovirus broadly, likely due to a different evolutionary process altogether. Punctuation in SARS-CoV-2 is probably neutral because most mutations were not positively selected and because the strength of the punctuational effect remained constant over time, at least until May 2020, and across continents. However, the small punctuational contribution to SARS-CoV-2 diversity is consistent with the founder effect arising from narrow transmission bottlenecks. Therefore, punctuation in SARS-CoV-2 may represent the macroevolutionary consequence (rate variation) of a microevolutionary process (transmission bottleneck).
