Published: November 2019

Belum ada kajian yang komprehensif tentang sejauh mana potensi energi angin guna menjadi sumber energi listrik terbarukan di Kota Tarakan. Oleh karena itu, penelitian ini mengusulkan pengembangan aplikasi analisis potensi angin sebagai sumber energi listrik terbarukan di Kota Tarakan menggunakan estimasi parameter Weibull berbasis metode Power Density. Frekuensi kecepatan angin diubah ke dalam bentuk kurva distribusi Weibull berdasarkan parameter bentuk (k) dan skala (s). Kemudian kedua parameter ini dicari menggunakan formulasi Power Density berdasarkan perhitungan rata-rata kecepatan angin dan rata-rata kubik kecepatan angin. Hasil eksperimen aplikasi usulan terhadap 1000 sampel data primer kecepatan angin yang diambil selama 100 hari menunjukkan nilai k dan s adalah 1,32 dan 1,90, sedangkan hasil eksperimen terhadap 48 sampel data sekunder yang diambil per bulan dalam 4 tahun menunjukkan nilai k dan s adalah 2,55 dan 3,42. Kedua jenis data ini mengindikasikan bahwa Kota Tarakan memiliki variabilitas angin tinggi dan lebih banyak berhembus angin kecepatan rendah < 4 m/s. Selain itu, rata-rata potensi daya angin yang dapat diserap turbin skala sangat kecil (diameter 2 m) hanya 13,60 s/d 32,48 watt, sehingga energi angin memiliki potensi yang sangat kecil untuk diterapkan sebagai pembangkit energi listrik di Kota Tarakan.

Penanganan evakuasi pasca bencana sangat membahayakan bagi korban maupun tim penyelamat yang akan melakukan evakuasi, khususnya area di dalam ruangan, ini disebabkan karena area yang belum terpetakan. Pada penelitian ini kami mengaplikasikan robot rescue untuk melakukan surve pada daerah pasca bencana, khususnya area di dalam ruangan (indoor area), Robot didesain dengan mekanik yang memungkinkan untuk melewati medan pasca bencana, sensor posisi yang diproses menggunakan metode odometry untuk melakukan rekam data pergerakan yaitu posisi dan orientasi dari robot, sensor observasi yang di proses dengan Kalman filter untuk melakukan deteksi lingkungan area robot pada saat melakukan navigasi, data sensor dan aktuator pada robot akan diproses lebih lanjut oleh GCS (Ground Control Station) untuk menghasilkan informasi berupa peta atau denah area (indoor) dan jalur evakusi alternatif dengan metode Flood Fill. Hasil penelitian menunjukkan bahwa, sistem navigasi menggunakan odometry pada area pasca bencana menghasilkan rekam posisi dan diperlukan perbaikan data posisi dan orientasi dengan menambahkan sensor absolute (menggunkan lokal GPS Global Positioning System atau IMU Intertial Measurement Unit). Fusion data motion model dan observation model menghasilkan pemetaan 3 dimensi dari area navigasi robot dan informasi jalur terpendek antara posisi victim dengan pintu emergencyyang terdekat, sehingga data peta dan jalur memungkinkan tim SAR (Search And Rescue) untuk lebih efektif dalam melakukan evakuasi terhadap korban pasca bencana pada area di dalam ruangan.

Estágio não formal: vivenciando experiências com a Educação Especial
Authors: Hendges Ana Paula Butzen 
Published: November 2019

O presente trabalho tem por objetivo descrever alguns pontos relevantes, observados com a realização do estágio de educação não-formal, este, desenvolvido em uma escola de educação especial mantida pela APAE em uma cidade da região noroeste do estado do Rio Grande do Sul. O estágio realizou-se com a turma da EJA etapa II, nas segundas-feiras e quartas-feiras, onde se ocupava o período diurno vespertino para a realização do mesmo. O tema norteador das atividades realizadas foi “Educação Alimentar e Ambiental”. Discutiu-se a possibilidade de levar algo que motivasse a participação dos estudantes e os levasse a construir o conhecimento através das atividades propostas, visando à autonomia dos mesmos. O estágio foi realizado nessa instituição por representar um desafio à formação docente e motivar na busca por um maior conhecimento sobre a educação especial e seus desafios, possibilitando melhor posicionamento frente a situações que possam vir a ocorrer no âmbito escolar, tanto nos próximos estágios quanto na atuação profissional. Compreendo que o trabalho desenvolvido na educação especial difere do que é desenvolvido nas escolas de ensino tradicional, e esse desafio me fez refletir constantemente sobre nossas metodologias de ensino, contribuindo significativamente para a minha formação docente.

Este texto apresenta uma reflexão sobre o desenvolvimento de uma prática investigativa com licenciandos de Ciências Biológicas - Licenciatura. A atividade foi realizada no componente de Laboratório de Ensino, que tem como um de seus objetivos o desenvolvimento e a demonstração de experimentos de Biologia, Física e Química para promover uma cultura investigativa e científica no ensino de Ciências e Biologia. Assim, foi proposto aos acadêmicos da 4ª fase, a construção de um terrário, mesmo que este não represente de forma fiel um ambiente natural. Porém, a partir desse miniecossistema é possível promover a introdução e discussão de conceitos básicos da Ecologia. Com a escrita deste relato busco apresentar a importância da realização de atividades experimentais na formação inicial de professores, uma vez que são práticas com potencialidades para desenvolver nos sujeitos a capacidade de aprender determinados aspectos da ciência e promover um processo de ensino investigativo e crítico que contribui para a aprendizagem dos alunos.
Hoje tenho aula. Que caderno eu levo?
Authors: Santos Rosemar Ayres dos 
Published: November 2019

A educação escolar, ao longo do tempo, sofreu inúmeras mudanças/transformações, mas, uma coisa perpassa por todo esse período e se mantém, as horas de planejamento de aulas para serem ministradas nas disciplinas escolares. E, para isso precisamos do caderno de planejamento, também, muitas vezes, denominado de diário de classe ou diário do professor. Como o próprio nome diz, é um caderno, seja de papel ou virtual, receptor das aulas planejadas a serem ministradas, nele depositamos, também, entre outras cosias, as observações/anotações durante as aulas e/ou pós-aulas, enfim, local no qual fazemos um mapeamento de tudo que necessita ser discutido em sala de aula. Assim, tem muitos registros, sejam das concepções de currículo, seja o currículo propriamente dito, sejam as metodologias de ensino, as reflexões da prática, dentre tantas possibilidades. Desse modo, nesse relato de experiência problematizarei a utilização desse documento/registro da vida em sala de aula de forma próxima a uma narrativa autobiográfica.

Authors: Maronn Tainá Griep 
Published: November 2019

Cada vez mais vêm sendo discutidas questões relacionadas à reciclagem e à reutilização de materiais. Assim sendo, a consciência e a responsabilidade de cada cidadão na busca de um mundo mais sustentável e próspero nos instiga a buscar métodos e iniciativas eficazes e simples para a preservação do planeta. Um desses métodos pode ser a conversão de pequenas ações em resoluções mais saudáveis e criativas. Dentre os quais pode ser utilizado, como exemplo, a construção de uma horta vertical. A construção da horta vertical teve como objetivos: propiciar momentos de reflexão acerca da responsabilidade ambiental; fazer a montagem da horta, usando plantas pequenas; compreender as contribuições de uma horta vertical no contexto da escola; e conscientizar a importância da reutilização de objetos recicláveis descartados no cotidiano. Esse trabalho buscou desenvolver uma horta vertical, reaproveitando garrafas PET na creche localizada no município de São Pedro do Butiá. A partir disso, o projeto realizado foi um meio encontrado de sensibilizar de que, com pouco trabalho e muita criatividade, é possível desenvolver atividades sustentáveis com custo mínimo.

Formation of Massive Protostellar Clusters—Observations of Massive 70 μm Dark Molecular Clouds
Authors: Li Shanghuo , Zhang Qizhou , Pillai Thushara , Stephens Ian W. , Wang Junzhi , Li Fei 
Published: November 2019

Abstract
We present Submillimeter Array observations of seven massive molecular clumps that are dark in the far-infrared for wavelengths up to 70 μm. Our 1.3 mm continuum images reveal 44 dense cores, with gas masses ranging from 1.4 to 77.1 M
⊙. Twenty-nine dense cores have masses greater than 8 M
⊙ and the other 15 dense cores have masses between 1.4 and 7.5 M
⊙. Assuming the core density follows a power law in radius ρ ∝ r
−b
, the index b is found to be between 0.6 and 2.1, with a mean value of 1.3. The virial analysis reveals that the dense cores are not in virial equilibrium. CO outflow emission was detected toward six out of seven molecular clumps and associated with 17 dense cores. For five of these cores, CO emissions appear to have line wings at velocities of greater than 30 km s−1 with respect to the source systemic velocity, which indicates that most of the clumps harbor protostars and thus are not quiescent in star formation. The estimated outflow timescale increases with core mass, which likely indicates that massive cores have longer accretion timescales than less massive ones. The fragmentation analysis shows that the masses of low-mass and massive cores are roughly consistent with thermal and turbulent Jeans masses, respectively.
A Reanalysis of the Fundamental Parameters and Age of TRAPPIST-1*

Published: November 2019

Abstract
We present the distance-calibrated spectral energy distribution (SED) of TRAPPIST-1 using a new medium-resolution (R ∼ 6000) near-infrared (NIR) Folded-port InfraRed Echellette (FIRE) spectrum and its Gaia parallax. We report an updated bolometric luminosity (L
bol) of −3.216 ± 0.016, along with semiempirical fundamental parameters: effective temperature T
eff = 2628 ± 42 K, mass = 90 ± 8 M
Jup, radius = 1.16 ± 0.03 R
Jup, and log g = 5.21 ± 0.06 dex. Its kinematics point toward an older age, while spectral indices indicate youth; therefore, we compare the overall SED and NIR bands of TRAPPIST-1 to field-age, low-gravity, and low-metallicity dwarfs of similar T
eff and L
bol. We find field dwarfs of similar T
eff and L
bol best fit the overall and band-by-band features of TRAPPIST-1. Additionally, we present new Allers & Liu spectral indices for the SpeX SXD and FIRE spectra of TRAPPIST-1, both classifying it as intermediate gravity. Examining T
eff, L
bol, and absolute JHKW1W2 magnitudes versus optical spectral type places TRAPPIST-1 in an ambiguous location containing both field and intermediate-gravity sources. Kinematics place TRAPPIST-1 within a subpopulation of intermediate-gravity sources lacking bona fide membership in a moving group with higher tangential and UVW velocities. We conclude that TRAPPIST-1 is a field-age source with subtle spectral features reminiscent of a low surface gravity object. To resolve the cause of TRAPPIST-1's intermediate-gravity indicators we speculate on two avenues that might be correlated to inflate the radius: (1) magnetic activity or (2) tidal interactions from planets. We find the M8 dwarf LHS 132 is an excellent match to TRAPPIST-1's spectral peculiarities along with the M9 β dwarf 2MASS J10220489+0200477, the L1 β 2MASS J10224821+5825453, and the L0 β 2MASS J23224684−3133231, which have distinct kinematics, making all four intriguing targets for future exoplanet studies.
Spin Parity of Spiral Galaxies. I. Corroborative Evidence for Trailing Spirals
Authors: Iye Masanori , Tadaki Ken-ichi , Fukumoto Hideya 
Published: November 2019

Abstract
Whether the spiral structure of galaxies is trailing or leading has been a subject of debate. We present a new spin parity catalog of 146 spiral galaxies that lists the following three pieces of information: whether the spiral structure observed on the sky is S-wise or Z-wise; which side of the minor axis of the galaxy is darker and redder, based on examination of Pan-STARRS and/or ESO/DSS2 red image archives; and which side of the major axis of the galaxy is approaching us based on the published literature. This paper confirms that all of the spiral galaxies in the catalog show a consistent relationship among these three parameters, without any confirmed counterexamples, which supports the generally accepted interpretation that all the spiral galaxies are trailing and that the darker/redder side of the galactic disk is closer to us. Although the results of this paper may not be surprising, they provide a rationale for analyzing the S/Z winding distribution of spiral galaxies, using the large and uniform image databases available now and in the near future, to study the spin vorticity distribution of galaxies in order to constrain the formation scenarios of galaxies and the large-scale structure of the universe.

Published: November 2019

Abstract
We investigate the scattering of strahl electrons by microinstabilities as a mechanism for creating the electron halo in the solar wind. We develop a mathematical framework for the description of electron-driven microinstabilities and discuss the associated physical mechanisms. We find that an instability of the oblique fast-magnetosonic/whistler (FM/W) mode is the best candidate for a microinstability that scatters strahl electrons into the halo. We derive approximate analytic expressions for the FM/W instability threshold in two different β
c regimes, where β
c is the ratio of the core electrons’ thermal pressure to the magnetic pressure, and confirm the accuracy of these thresholds through comparison with numerical solutions to the hot-plasma dispersion relation. We find that the strahl-driven oblique FM/W instability creates copious FM/W waves under low-β
c conditions when

, where U
0s is the strahl speed and w
c is the thermal speed of the core electrons. These waves have a frequency of about half the local electron gyrofrequency. We also derive an analytic expression for the oblique FM/W instability for β
c ∼ 1. The comparison of our theoretical results with data from the Wind spacecraft confirms the relevance of the oblique FM/W instability for the solar wind. The whistler heat-flux, ion-acoustic heat-flux, kinetic-Alfvén-wave heat-flux, and electrostatic electron-beam instabilities cannot fulfill the requirements for self-induced scattering of strahl electrons into the halo. We make predictions for the electron strahl close to the Sun, which will be tested by measurements from Parker Solar Probe and Solar Orbiter.
Evidence of Outflow-induced Soft Lags of Galactic Black Holes
Authors: Patra Dusmanta , Chatterjee Arka , Dutta Broja G. , Chakrabarti Sandip K. , Nandi Prantik 
Published: November 2019

Abstract
The nature of lag variation of Galactic black holes remains enigmatic mostly because of nonlinear and nonlocal physical mechanisms which contribute to the lag of the photons coming from the region close to the central black holes. One of the widely accepted major sources of the hard lag is the inverse Comptonization mechanism. However, the exact reason, or reasons, for soft lags has yet to be identified. In this paper, we report a possible correlation between radio intensities of several outbursting Galactic black hole candidates and amounts of soft lag. The correlation suggests that the presence of major outflows or jets changes the disk morphology along the line of sight of the observer which produces soft lags.
Politique et éthique des grandes entreprises : l’univers dystopique des blade runner 2019 et 2049
Authors: Lacroix Isabelle 
Published: November 2019

Nombre de grands classiques de la science-fiction présentent un futur où les dirigeants des grandes entreprises règnent sur les sociétés humaines. Entre la BNL du film Wall-E et les multinationales qui contrôlent les Nations Unies dans la Trilogie martienne de Kim Stanley Robinson, la représentation d’entreprises menaçantes pour l’humanité prend de multiples formes. Si les œuvres de science-fiction parlent bien davantage de l’époque qui les a vu naître que d’un futur encore à advenir, que nous racontent ces œuvres sur nos sociétés ? Sur nos craintes et nos dilemmes éthiques ? Pour Lysa Rivera (2012), et il s’agit de l’orientation qui guide notre analyse, la science-fiction pose d’abord et avant tout la question centrale suivante : « qu’avons-nous fait en tant que société pour aller jusque-là ? ». Cette approche suppose d’observer la science-fiction comme une possibilité d’anticipation fondée sur des données actuelles et d’en faire une projection orientée par les facteurs sociétaux choisis au départ par les créateurs. À cet égard, une œuvre nous semble riche en réflexion éthique et politique, soit les deux volets de la saga des Blade runner 2019 (adapté au cinéma en 1982) et Blade runner 2049 (adapté au cinéma en 2017). Ce qui nous intéresse dans cette œuvre est l’aspect assumé du pouvoir fortement concentré entre les mains des entreprises technologiques alors que l’objectif de littéralement créer une nouvelle race à partir d’androïdes « plus humains que les humains » est affirmé par la voix de Niander Wallace, dans l’épisode de 2049, qui croit que toutes les sociétés se sont développées en s’appuyant sur une « main-d’œuvre jetable ». Nous proposons, à partir d’une approche comparative développée en 2016 et inspirée de Jean-Pierre Béland et Georges Legault (2012), d’observer l’évolution de la représentation du pouvoir des entreprises technologiques entre les deux volets de la saga Blade runner . Une analyse de contenu simple nous permettra d’étudier ces représentations, de les comparer entre elles (2019 et 2049) en ayant en tête les époques et contextes sociopolitiques qui les ont vu émerger.
