Tratamento dos conteúdos da educação básica, com ênfase em uma abordagem axiomática e avançada.
A SOCIO-ECOLOGICAL TURN IN MATHEMATICS EDUCATION: REFLECTING ON CURRICULUM INNOVATION
Authors: Coles Alf
Published: January 2022

This article proposes that mathematics education has reached a socio-ecological turn. I identify three strands to this turn. Firstly, current advances in the sciences point to the interconnectivity of life and the ecologies living within and without human bodies. Secondly, advances in the humanities point towards the need to re-think human and non-human relations. And thirdly, the ecological precarity of the world points to the need to re-think the purposes and aims of mathematics education. Two possible curriculum innovations, in response to a socio-ecological turn, are offered. In one case, the curriculum starts from a pressing ecological issue facing a community. In the second case, in a more standard schooling context, a communal mathematics is promoted, with an emphasis on students asking their own questions. A commonality is the dramatization of the curriculum.
DIALOGIC LEARNING: FROM AN EDUCATIONAL CONCEPT TO DAILY CLASSROOM TEACHING
Authors: Gallin Peter
Published: January 2022

This article presents the genesis and the main elements that compose the cycle of the dialogic learning. The development of the concept of self-controlled and sustainable learning is based on a personal encounter between two teachers of entirely different subjects: Mathematics and German. Two examples show how uncomplicated teaching mathematics in the classroom can be, once the teacher has gained the courage to trust in the capabilities of the children. The three German textbooks “Ich-Du-Wir” (“I-You-We”) for mother tongue and mathematics in the first six years of elementary school provide support.

Published: January 2022

No atual cenário de crescente desenvolvimento tecnológico no qual estamos inseridos, tem se tornado cada vez mais presente a necessidade de desenvolvermos nosso pensamento crítico e criativo, em especial em matemática, dada tamanha aplicação desta área de saber. Sendo assim, há que se falar não apenas em aprimorarmos nossas metodologias de ensino de matemática, como também, inserirmos teorias e práticas ligadas ao estímulo deste tipo de pensamento desde a formação docente inicial. Neste artigo, relatamos uma investigação desenvolvida junto a um grupo de bolsistas do Programa Institucional de Bolsas de Iniciação à Docência (Pibid), subprojeto Matemática, de uma Universidade pública do Distrito Federal, cuja organização didática está embasada no estímulo ao pensamento crítico e criativo em matemática de estudantes do ensino médio. Foram aplicados questionários com questões discursivas para os bolsistas, cujas respostas foram tratadas sob a perspectiva da análise de conteúdo. Por resultados, foi possível inferir a partir das respostas dos bolsistas que esses passaram não apenas a conhecer a temática e desejarem que seja incluída em seus programas de formação como também a recomendar a aplicação do modelo de oficinas utilizado.

Published: January 2022

Este trabalho apresenta a elaboração de materiais didáticos complementares desenvolvidos com a orientação e supervisão das autoras pelos residentes de matemática da E. E. Raul de Leoni, Viçosa-MG, durante o período de outubro de 2020 a janeiro de 2021. Buscamos junto aos residentes, estudantes do curso de matemática da Universidade Federal de Viçosa (UFV), MG, a elaboração de algumas aulas que pudessem ser atrativas aos alunos para revisar diversos conteúdos. Desta forma nosso trabalho consiste na elaboração de um material didático complementar, um pequeno livro, com vistas a abordar diversos conteúdos da matriz curricular do 9º ano da Educação Básica, na área da matemática. Cada conteúdo é abordado de forma singular, por meio de jogos, softwares matemáticos, lista de exercícios e desafios, que podem ser usados como uma forma mais interativa e que facilita a compreensão destes conceitos. A elaboração do material teve por base os PETs (Programa de Ensino Tutorado) material didático disponibilizado pela Secretaria do Estado de Educação de Minas Gerais – SEE/MG. As subáreas da Matemática abordadas foram: Geometria e Álgebra. Em Geometria, os conteúdos específicos apresentados foram: Teorema de Tales, semelhança de triângulos e ângulos notáveis no triângulo. Já em álgebra os conteúdos específicos tradados foram: resolução de equações do segundo grau, função afim e função quadrática. Todos estes conteúdos foram apresentados para fazer com que os alunos participem mais das aulas, nas quais esses conteúdos são abordados. Umas das vantagens da aplicação dos conteúdos descritos no livro é o fato de eles poderem ser utilizados dentro deste contexto remoto, onde a interação com os alunos é mais limitada, podendo assim chamar a atenção dos alunos para eles adquirirem uma aprendizagem mais significativa.

Elevator Tab Model and Aerodynamic Hinge Moment Variation Effect on Flutter Analysis of a Small Commuter Aircraft
Authors: Muchamad Bayu Sakti Pratama  , Erwin Sulaeman  , Kezia Grace Walesasi  , Ari Legowo
Published: January 2022

Investigation of flutter instability analysis is an important process during design phase and certification of an aircraft. Without proper analysis, the effect of modification at later stage of design process could come at high cost and risk. The present work examines detailed elevator tab model which could result in a more critical tab flutter speed. The present investigation of aerodynamic hinge moment variation effect on flutter analysis also shows a significant decrease in the flutter speeds. Three configurations involving elevator trim tab and balance tab fixed/free mechanism are investigated. Investigation of flutter sensitivity to tab rotational frequency and tab bending/torsion frequency was performed to determine the minimum tab rotational frequency requirement, so that it can be used as reference in design process. Variation of Mach number (for Configuration 1) and elevator aerodynamic hinge moment (all configurations) are performed. It is found that the aerodynamic variation takes effect when the mode involves both trim and balance tabs and tab elastic modes (e.g., tab torsion). It is found also that the most critical flutter case is for Configuration 3 where the trim and balance tabs are not fixed (independent). The result suggests that control surface tabs need to be modelled from the early design process, so that if any critical flutter appears and needs to be responded by a change in design, it can be implemented earlier and therefore avoid any costly risk.

Curve diffuser is often used in HVAC and wind tunnel systems to provide pressure recovery and avoid excessive energy loss to the surrounding environment. Performance of curve diffuser is disturbed mainly by the presences of flow separation and secondary flow vortices occurred due to the effect of turning angle, in which scarce literature found. In this study, the effect of turning angle from 30° to 180° configured with an area ratio of 1.60 to 4.00 and inflow Reynolds number of 5.934x104 – 1.783x105 on loss characteristics and flow rectification of curve diffuser is investigated with optimum configuration is proposed. Performance of curve diffuser is evaluated in terms of pressure recovery and flow uniformity using ANSYS CFD equipped with validated Standard k-ɛ model (ske) and enhanced wall treatment of y+ = 1.2 - 1.7. Results show that performance of pressure recovery and flow uniformity decreases respectively by 85.71% and 45.84% as the angle of turn increases from 30° to 180°. Curve diffuser with minimum angle of turn 30o, optimum area ratio 2.16 and intermediate Rein 8.163x104 turns out to be the best configuration to provide pressure recovery of 0.399 and flow uniformity of 3.630 m/s.

Energy efficiency and environmental sustainability are important aspects in ship design and operation. Hull-shape optimization, hull cleaning and coating, and the use of appendages are, among others, well-known efforts to reduce ship fuel consumption. Regarding energy efficiency and environmental sustainability, it is possible to effectively reduce the resistance of an existing catamaran by retrofitting a foil system to it. In this study, a foil system is designed and retrofitted to a catamaran to reduce its total resistance. Reynolds-averaged Navier-Stokes simulations, utilizing k-w SST turbulence model, were performed to study the effects of the foil system on the vessel’s total resistance. Free surface effects were modelled, i.e., the generation of waves due to the vessel’s movement on the water surface. The foil system affects the wetted surface area, running sinkage and trim, and the wave pattern generated by the vessel, which ultimately affect the vessel’s total resistance. At relatively low speeds (Fr < 0.7), an increase of the total resistance, reaching a value of approximately 11%, was observed due to the foil system. However, at higher speeds (Fr > 0.7), the foil system decreases the total resistance, reaching a value of approximately 32% at the service speed (Fr = 1.24). The 32% resistance reduction at the service speed is promising in view of the intended purpose of the foil system as an energy saving device.
A Numerical Model for Ash Deposition Based on Actual Operating Conditions of a 700 MW Coal-Fired Power Plant: Validation Feedback Loop via Structural Similarity Indexes (SSIMs)
Authors: Mohammad Nurizat Rahman  , Nor Fadzilah Binti Othman
Published: January 2022

The combustion of coals will result in significant ash-related issues, which will ultimately lead to the efficiency loss of coal-fired utility boilers. While there have been numerous attempts to predict ash deposition dynamics using numerical approaches, the majority of these models were constructed using experimental data from pilot-scale furnaces and without integration with combustion models. Therefore, the current study collects meaningful power plant data from ash sampling activities at one of Malaysia's 700 MW sub-critical coal-fired power plants, enabling the ash deposition behavior in a real coal-fired utility boiler to be adequately captured and converted into a reliable ash deposition numerical model. The validation feedback loop of the ash deposition model was run using in-situ measurement data (ash sampling picture) and the actual power plant operating conditions during the ash sampling activities. The image processing algorithm was used to determine the degree of similarity between the actual ash sampling image and the predicted ash deposition image from the numerical model. Prior to the validation feedback loop, the overall numerical model (solver, combustion, turbulence, radiation) was successfully validated with the FEGT from the actual power plant, revealing a difference of less than 5 %. The current study found that the baseline ash deposition model (created from experimental data) underestimates the quantity of ash deposition gathered. The validation feedback loop of the baseline ash deposition model successfully established a new set of impaction efficiency constants, which increased the similarity of the images between the actual and predicted ash depositions. The current study's drawback, however, is mostly in the validation basis, which is largely qualitative in nature. Although the Structural Similarity Index (SSIM) value is useful for comparing the similarity of images between actual and predicted ash depositions, a more quantitative measurement that can provide extra meaningful data points and higher accuracy on the deposited ash is preferable. However, based on this modified version of the ash deposition model, the agreement is found to be satisfactory in terms of gaining a rudimentary insight of the ash deposition behavior in a coal-fired boiler.

Touring Italian Rhodes
Authors: McGuire Valerie
Published: January 2022

Starting in 1912, the Italian state commenced a series of initiatives aimed at the restoration of medieval and Ottoman heritage in the island of Rhodes. Preservation programs eventually inspired a master plan for new architecture and infrastructure which could make the island well-known among and appeal to international tourists. Italian urbanism brought Rhodes into economies of colonial representation and into line with the ‘chronopolitics’ of the Fascist state. The chapter describes urban planning, tourism sites, and the re-grafting of the Ottoman past in the creation of a new cultural landscape, and discusses the framing of the island in photography, guidebooks and travel memoirs. The grooming of Rhodes implied exoticization, the making of the island into an object of colonial fascination, but also modernization and modernity for touristic consumption. Although the cultural landscape evolved alongside shifts in politics of the Fascist regime, the careful curation of Rhodes for an experience of ‘Mediterranean’ culture and holiday is one of the strongest legacies of Italy’s colonial rule in the region.
Everyday Fascism in the Aegean
Authors: McGuire Valerie
Published: January 2022

Italy’s rule in the Southeast Aegean is nearly synonymous with the locution, una faccia, una razza (one face, one race), and has shaped cultural representations as well as oral narratives about the occupation. Previously, studies have linked this trope to the myth of Italians as ‘good people’. Without discounting the possibility that the local community may have had positive relations and experienced benefits to Italian rule, this chapter assesses to how the trope may encapsulate a lived experience of the deeply nationalist ideology that underpinned the Italian empire. Oral and archival sources make visible the ways that the local population was brought into Italian nation-building projects. Carrying forward the book’s larger discussion of citizenship and belonging, the chapter focuses in particular on the Italian state’s language policy in the Aegean as one of the key instruments adopted in order to spread a wider sense of belonging to the Italian empire. It considers how these forms of national belonging have lived on in present-day ideas about European identity.
CAN BITCOIN BE A SAFE HAVEN IN FEAR SENTIMENT?
Authors: Su Chi-Wei , Xi Yuan , Tao Ran , Umar Muhammad
Published: January 2022

This paper explores how fear sentiment affects the price of Bitcoin by employing the rolling-window Granger causality tests. The analysis reveals negative influences from the volatility index (VIX) to Bitcoin price (BTC), which ascertains that Bitcoin can not be considered a haven in fear sentiment. Due to the liquidity in economic downside risks, BTC may decrease with high VIX to hedge losses, increasing during low VIX periods. The empirical results conflict with the intertemporal capital asset pricing model, which underlines that the increasing VIX can promote the price of Bitcoin. In turn, BTC positively impacts VIX, which shows that Bitcoin price can be treated as the main indicator for a more comprehensive analysis of the fear index. Under severe global uncertainty and changeable fluctuation of market sentiment, investors can optimize investment decisions based on market fear sentiment. The government can also consider VIX to grasp the trend of BTC to participate in cryptocurrency speculation effectively.

Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160 B-type stars with light curves collected by the TESS space mission using three different procedures (fast Fourier transform, Lomb–Scargle, and wavelet techniques), accompanied by rigorous visual inspection in the search for rotation periodicities. This effort provides rotational periodicities for 6 new TESS B-type stars and confirmed periodicities for 22 targets with rotation periods previously listed in the literature. For the other 61 stars, already classified as possible rotational variables, we identify noisy, pulsational, binarity, or ambiguous variability behavior rather than rotation signatures. The total sample of 28 potential rotators shows an overlap of different classes of rotational variables, composed of α
2 Canum Venaticorum, rotating ellipsoidal, and SX Arietis stars. The combination of the three techniques applied in our analysis offers a solid path to overcome the challenges in the discrimination of rotation from other variabilities in stellar light curves, such as pulsation, binarity, or other effects that have no physical meaning. Finally, the rotational periodicities reported in the present study may represent important constraints for improving stellar evolution models with rotation, as well as asteroseismic studies of hot stars.

We present initial results from a large spectroscopic survey of stars throughout M33's stellar disk. We analyze a sample of 1667 red giant branch (RGB) stars extending to projected distances of ∼11 kpc from M33's center (∼18 kpc, or ∼10 scale lengths, in the plane of the disk). The line-of-sight velocities of RGB stars show the presence of two kinematical components. One component is consistent with rotation in the plane of M33's H i disk and has a velocity dispersion (∼19 km s−1), consistent with that observed in a comparison sample of younger stars, while the second component has a significantly higher velocity dispersion. A two-component fit to the RGB velocity distribution finds that the high-dispersion component has a velocity dispersion of

km s−1 and rotates very slowly in the plane of the disk (consistent with no rotation at the <1.5σ level), which favors interpreting it as a stellar halo rather than a thick disk population. A spatial analysis indicates that the fraction of RGB stars in the high-velocity-dispersion component decreases with increasing radius over the range covered by the spectroscopic sample. Our spectroscopic sample establishes that a significant high-velocity-dispersion component is present in M33's RGB population from near M33's center to at least the radius where M33's H i disk begins to warp at 30′ (∼7.5 kpc) in the plane of the disk. This is the first detection and spatial characterization of a kinematically hot stellar component throughout M33's inner regions.

Ultracool dwarf stars and brown dwarfs provide a unique probe of large-scale Galactic structure and evolution; however, until recently spectroscopic samples of sufficient size, depth, and fidelity have been unavailable. Here, we present the identification of 164 M7-T9 ultracool dwarfs in 0.6 deg2 of deep, low-resolution, near-infrared spectroscopic data obtained with the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) instrument as part of the WFC3 Infrared Spectroscopic Parallel Survey and the 3D-HST survey. We describe the methodology by which we isolate ultracool dwarf candidates from over 200,000 spectra, and show that selection by machine-learning classification is superior to spectral index-based methods in terms of completeness and contamination. We use the spectra to accurately determine classifications and spectrophotometric distances, the latter reaching to ∼2 kpc for L dwarfs and ∼400 pc for T dwarfs.
Numerical Modeling of Suprathermal Electron Transport in the Solar Wind: Effects of Whistler Turbulence with a Full Diffusion Tensor
Authors: Tang Bofeng , Zank Gary P. , Kolobov Vladimir I.
Published: January 2022

The electron VDF in the solar wind consists of a Maxwellian core, a suprathermal halo, a field-aligned component strahl, and an energetic superhalo that deviates from the equilibrium. Whistler wave turbulence is thought to resonantly scatter the observed electron velocity distribution. Wave–particle interactions that contribute to Whistler wave turbulence are introduced into a Fokker–Planck kinetic transport equation that describes the interaction between the suprathermal electrons and the Whistler waves. A recent numerical approach for solving the Fokker–Planck kinetic transport equation has been extended to include a full diffusion tensor. Application of the extended numerical approach to the transport of solar wind suprathermal electrons influenced by Whistler wave turbulence is presented. Comparison and analysis of the numerical results with observations and diagonal-only model results are made. The off-diagonal terms in the diffusion tensor act to depress effects caused by the diagonal terms. The role of the diffusion coefficient on the electron heat flux is discussed.

We describe the public release of the Cluster Monte Carlo (CMC) code, a parallel, star-by-star N-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’s method, where the cumulative effect of many two-body encounters is statistically reproduced as a single effective encounter between nearest-neighbor particles on a relaxation timescale. The star-by-star approach allows for the inclusion of additional physics, including strong gravitational three- and four-body encounters, two-body tidal and gravitational-wave captures, mass loss in arbitrary galactic tidal fields, and stellar evolution for both single and binary stars. The public release of CMC is pinned directly to the COSMIC population synthesis code, allowing dynamical star cluster simulations and population synthesis studies to be performed using identical assumptions about the stellar physics and initial conditions. As a demonstration, we present two examples of star cluster modeling: first, we perform the largest (N = 108) star-by-star N-body simulation of a Plummer sphere evolving to core collapse, reproducing the expected self-similar density profile over more than 15 orders of magnitude; second, we generate realistic models for typical globular clusters, and we show that their dynamical evolution can produce significant numbers of black hole mergers with masses greater than those produced from isolated binary evolution (such as GW190521, a recently reported merger with component masses in the pulsational pair-instability mass gap).
