Published: August 2019

Esta pesquisa buscou investigar a possibilidade de utilizar o software Boardmaker como recurso para apoiar os processos de aquisição da leitura e da escrita, na perspectiva da educação inclusiva. O estudo, de caráter qualitativo, foi desenvolvido junto a dezesseis crianças do segundo ano do ensino fundamental, em uma escola do município de Arroio do Meio. A metodologia envolveu as seguintes ações: revisão bibliográfica; estudo do software; proposição, realização e análise de atividades didático-pedagógicas voltadas para o desenvolvimento da leitura e da escrita. As reflexões sobre Informática e Educação e sobre Tecnologia Assistiva encontram-se fundamentadas em autores como Papert (1994), Moran (2000), Sartoretto e Bersch (2014). Para discutir as questões referentes a alfabetização e consciência fonológica, buscou-se apoio em Ferreiro (1991), Soares (2010), Maluf e Cardoso-Martins (2013), e Adams [et. Al] (2006). A análise dos dados indica que o software Boardmaker pode contribuir para renovar práticas pedagógicas na alfabetização por meio da elaboração de atividades interativas que exploram texto, imagens e sons.
Repertoire Remix: Integrating Musical Preferences from Remote Audience in a Live Networked Improvisation
Authors: Van Troyer Akito 
Published: August 2019

Repertoire Remix enables remote audience members to dynamically suggest their musical preferences for live web-streaming musical improvisation sessions. The semantic web interface encourages remote participants to collaboratively use “stirring” mouse gestures to influence the size of graphical bubbles that contain composers’ names. The accumulated weight is then interpreted by musicians to improvise. This paper documents the first pilot run of the Repertoire Remix system, explores challenges in designing a real-time shared music-style arranging system for networked live improvisation, and interprets the resulting performance by assessing the participants’ mouse gestures collected during the pilot run.

Este trabalho relata a experiência de estabelecer uma metodologiade testes de qualidade subjetiva de áudio, duplamente cegos tipo AB ou ABX, para avaliação de conversores analógico/digitais. Uma série de experiências foram feitas na tentativa de identificar diferenças audíveis entre vários equipamentos. Relatamos tanto os insucessos como os resultados finais positivos, isto é, com a capacidade de distinguí-los, para salientar a dificuldade e o potencial desse tipo de experimento. A principal contribuição desse artigo está na documentação da construção desse processo, identificando os parâmetros que foram necessários para que tivesse êxito. Conclui-se principalmente, pela variedade de resultados, que testes onde os indivíduos não conseguem perceber uma diferença não provam que ela não é perceptível, mas apenas que o teste falhou em identificá-la. São apresentadas as conclusões parciais que foram observadas com os conversores testados, evidenciando a qualidade relativamente limitada de equipamentosprofissionais de alto custo.

The Structure of the Orion Nebula in the Direction of θ1 Ori C
Authors: Abel N. P. , Ferland G. J. , O’Dell C. R. 
Published: August 2019

Abstract
We have used existing optical emission and absorption lines, [C ii] emission lines, and H i absorption lines to create a new model for a central column of material near the Trapezium region of the Orion Nebula. This was necessary because recent high spectral resolution spectra of optical emission lines and imaging spectra in the [C ii] 158 μm line have shown that there are new velocity systems associated with the foreground Veil and the material lying between θ
1 Ori C and the main ionization front of the nebula. When a family of models generated with the spectral synthesis code Cloudy were compared with the surface brightness of the emission lines and strengths of the Veil absorption lines seen in the Trapezium stars, distances from θ
1 Ori C were derived, with the closest, highest ionization layer being 1.3 pc. The line-of-sight distance of this layer is comparable with the size of the inner Huygens region in the plane of the sky. These layers are all blueshifted with respect to the Orion Nebula Cluster of stars, probably because of the pressure of a hot central bubble created by θ
1 Ori C's stellar wind. We find velocity components that are ascribed to both sides of this bubble. Our analysis shows that the foreground [C ii] 158 μm emission is part of a previously identified layer that forms a portion of a recently discovered expanding shell of material covering most of the larger Extended Orion Nebula.
Differential Interferometric Signatures of Close Binaries of Supermassive Black Holes in Active Galactic Nuclei

Published: August 2019

Abstract
In the present paper, we explore opportunities of applying the GRAVITY at the Very Large Telescope Interferometer with unprecedented spatial resolution to identify close binaries of supermassive black holes (CB-SMBHs) in active galactic nuclei (AGNs). Each supermassive black hole is assumed to be separately surrounded by its own broad-line regions (BLRs) composed of clouds with virialized motion. Composition of the binary orbital motion and the virial motion of clouds in each BLR determines the projected velocity fields and hence differential phase curves, which are obviously different from that of a single BLR. We calculate emission line profiles and differential phase curves of CB-SMBHs for the GRAVITY. For the simplest case, in which angular momenta of two BLRs and orbital motion are parallel, a phase plateau generally appears in the phase curves. For other combinations of the angular momentum, the plateau is replaced by new peaks and valleys variously depending on the situation. Given a combination, phase curves are also sensitive to changes of parameters of CB-SMBHs. All these features are easily distinguished from the well-known S-shaped phase curves of a single BLR, so that the GRAVITY is expected to reveal signals of CB-SMBH from candidates of AGNs. With joint analysis of observations of reverberation-mapping campaigns, we can reliably identify CB-SMBHs, and measure their orbital parameters in the meanwhile. This independent measurement of the orbital parameters also has implications to analysis of pulsar timing array observations for properties of low-frequency gravitational waves in future.

Abstract
Supernova neutrinos are crucially important to probe the final phases of massive star evolution. As is well known from observations of SN 1987A, neutrinos provide information on the physical conditions responsible for neutron star formation and on the supernova explosion mechanism. However, there is still no complete understanding of the long-term evolution of neutrino emission in supernova explosions, although there are a number of modern simulations of neutrino radiation hydrodynamics, which study neutrino emission at times less than one second after the bounce. In the present work we systematically calculate the number of neutrinos that can be observed in Super-Kamiokande over periods longer than 10 seconds using the database of Nakazato et al. anticipating that neutrinos from a Galactic supernova can be detected for several tens of seconds. We find that for a supernova at a distance of 10 kpc, neutrinos remain observable for longer than 30 s for a low-mass neutron star (1.20 M
⊙ gravitational mass) and even longer than 100 s for a high-mass neutron star (2.05 M
⊙). These scenarios are much longer than the observations of SN 1987A and longer than the duration of existing numerical simulations. We propose a new analysis method based on the cumulative neutrino event distribution as a function of reverse time from the last observed event, as a useful probe of the neutron star mass. Our result demonstrates the importance of complete modeling of neutrino light curves in order to extract physical quantities essential for understanding supernova explosion mechanisms, such as the mass and radius of the resulting neutron star.
Using Spatial Curvature with H ii Galaxies and Cosmic Chronometers to Explore the Tension in H0

Published: August 2019

Abstract
We present a model-independent measurement of spatial curvature Ω
k
in the Friedmann–Lemaître–Robertson–Walker universe, based on observations of the Hubble parameter H(z) using cosmic chronometers, and a Gaussian process (GP) reconstruction of the H ii galaxy Hubble diagram. We show that the imposition of spatial flatness (i.e., Ω
k
= 0) easily distinguishes between the Hubble constant measured with Planck and that based on the local distance ladder. We find an optimized curvature parameter

when using the former (i.e.,

), and

for the latter (

). The quoted uncertainties are extracted by Monte Carlo sampling, taking into consideration the covariances between the function and its derivative reconstructed by GP. These data therefore reveal that the condition of spatial flatness favors the Planck measurement, while ruling out the locally inferred Hubble constant as a true measure of the large-scale cosmic expansion rate at a confidence level of ∼3σ.
The Birth of a Jet-driven Twin CME and Its Deflection from Remote Magnetic Fields

Published: August 2019

Abstract
We report the formation of a complicated coronal mass ejection (CME) on 2015 August 23 by using the high temporal and high spatial resolution multi-wavelength observations taken by the Solar Dynamic Observatory and the Solar and Heliospheric Observatory. The CME exhibited both jetlike and bubble-like components simultaneously, and therefore, we call it a twin CME. Detailed imaging and kinematic analysis results indicate that the twin CME was evolved from the eruption of a mini-filament-driven blowout jet at the eastern edge of an equatorial coronal hole, in which the activation of the mini-filament was tightly associated with the continuous flux cancellation and quasi-periodic jetlike activities in the filament channel. Due to the magnetic reconnection between the filament and the ambient open field lines, the filament broke partially at the northern part and resulted in an intriguing blowout jet in the southern direction. It is interesting that the ejecting jet was deflected by a group of remote open field lines, which resulted in the significant direction change of the jet from southward to eastward. Based on the close temporal and spatial relationships among the jet, filament eruption, and the twin CME, we conclude that the jetlike CME should be the coronal extension of the jet plasma, while the bubble-like one should have originated from the eruption of the mini-filament confined by the closed magnetic fields at the jet base.
The effect of posture on ventilatory muscle function and lung function
Authors: Gounden P. 
Published: August 2019

The purpose of this study was to determine the influence of posture on ventilatory muscle strength and on lung function.Maximum static inspiratory pressures (MIPS), maximum static expiratory pressures (MEPS) and lung function measurements (FVC, FEV1, PEFR) were obtained in three different body positions in 57 normal subjects and in 16 asthmatic patients.Statistical analysis of the data obtained showed that changes in position influence the ventilatory muscle function and lung function values.The sitting lean forward and the sitting erect positions were the better positions in the normal group. The findings revealed that the sitting lean forward position was the optimum position for the asthmatic group (p 0,001).

Authors: Li Jian-Fang , Xie Liang-Jun , Qin Lu-Ping , Liu Yi-Fei , Zhang Ting-Jie , Huang Yong , Cheng Mu-Hua 
Published: August 2019

Background & objectives:
The nature of adaptable change of B-cell lymphoma-2 (BCL-2) and/or Bcl2-associated X protein (BAX) gene expression in the human peripheral blood mononuclear cells (PBMCs) irradiated by radioiodine in thyroid diseases therapy is not fully understood. In this study, the alternation of apoptotic gene expression was evaluated while the PBMCs collected from healthy volunteers were irradiated by the radioiodine-131 (131I).

Methods:
Fasting blood samples were obtained from healthy volunteers. PBMCs from group 0 to 6 were incubated and exposed to different doses of 131I in cell suspension for 6, 12, 24 and 48 h. The apoptosis rates and expression of BCL-2 and BAX genes of PBMCs were examined.

Results:
The apoptosis rate in the human PBMCs was gradually enhanced after six hour irradiation. The values of BCL-2 and BAX gene expression in groups 1-6 were higher than in group 0 within 6 h of irradiation, and then, these were decreased gradually from 6 to 12 h. BCL-2 gene expression increased in groups 1-3 after 12 h irradiation, but there was no difference in groups 4-6. The ratio of BCL-2/BAX gene expression among groups 4-6 gradually decreased during the period from 6 to 12 h, and it was significantly lower than in the group 0 at 12, 24 and 48 h.

Interpretation & conclusions:
The expression of BCL-2 and BAX genes was initially upregulated following irradiation. Later, the balance of BCL-2/BAX genes expression was adjusted, and then, PBMCs underwent apoptosis at higher doses of radiation.
Cloning, expression & evaluation of potential immunogenic recombinant capsid premembrane protein of West Nile virus
Authors: Kumar Jyoti S. , Rathinam Sivakumar , Karothia Divanyshi , Parida Manmohan 
Published: August 2019

Background & objectives:
West Nile virus (WNV) is a neurotropic flavivirus that has emerged globally as a significant cause of viral encephalitis. The early confirmatory diagnosis of WNV infections is important for timely clinical management and in areas where multiple flaviviruses are endemic. Diagnosis of WNV infection is primarily based on serodiagnosis, followed by virus isolation and identification. The aim of this study was to develop and evaluate a highly sensitive and specific immunoglobulin M (IgM) ELISA using the recombinant CprM protein (rWNV-CprM) for rapid, early and accurate diagnosis of WNV.

Methods:
The gene coding for the CprM protein of WNV was cloned and expressed in pET 28a vector followed by purification. An indirect IgM microplate ELISA using purified rWNV-CprM protein was optimized having no cross-reactivity with healthy human serum and serum samples obtained from patients with dengue and Japanese encephalitis viruses infection.

Results:
The comparative evaluation of this rWNV-CprM protein-specific IgM ELISA with plaque reduction neutralization test using 105 blood samples collected from patients suspected to have acute WNV infection revealed 98 per cent concordance with sensitivity and specificity of 100 and 97 per cent, respectively.

Interpretation & conclusions:
The recombinant CprM protein-based WNV-specific ELISA reported in this study may be useful for rapid screening of large numbers of blood samples in endemic areas during outbreaks.
Conditions aux limites pour le modèle du drainage de sables en une et deux dimensions

Published: August 2019

The study of soil pollution and treatment need a good knowledge of hydrodynamic properties. Therefore, models and drainage experiences are commonly used. In order to valid the models, boundary conditions are required. Drainage modelling in sand has been performed and compared with experimental results obtained in one-dimension column (1D) and in two-dimension pilot (2D). Comparison was established by testing different boundary conditions at the device outlet and by using concordance indicators. The studied experimental results are : outlet flow, cumulated volume at the pilot outlet, hydraulic load values and saturation at different levels of the pilot. Experiments indicate that a Neumann condition at the outlet is more suitable than a Dirichlet constant pressure condition whether for 1D or 2D experiences.
L’étude de la pollution/dépollution des sols nécessite une bonne connaissance de leurs propriétés hydrodynamiques. Pour ce faire, l’utilisation de modèles et d’expériences de drainage constitue un outil couramment utilisé. Afin de valider les modèles, il est nécessaire de fixer des conditions aux limites (CL). La modélisation du drainage dans un milieu sableux a été effectuée et confrontée à des résultats d’expériences obtenus en colonne à une dimension (1D) et en pilote à deux dimensions (2D). La comparaison est réalisée en testant différentes CL à la sortie du dispositif et avec l’utilisation d’indicateurs de concordance. Les résultats expérimentaux étudiés sont ceux du débit de sortie, le volume cumulé à la sortie, les valeurs de la charge hydraulique et de la saturation à différents points des dispositifs. Les tests ont montré qu’une condition de sortie de type Neumann était plus adéquate qu’une condition de pression constante de type Dirichlet, que ce soit dans le cas d’une expérience en 1D ou en 2D.

Published: August 2019

ABSTRACTA 17 mo old female Jack Russell terrier was diagnosed with unilateral primary malignant nephroblastoma. The dog presented with polyuria and polydipsia. Laboratory tests revealed polycythemia and elevated serum erythropoietin levels. Diagnostic imaging (i.e., MRI) revealed a unilateral renal mass without spinal cord involvement. Nephrectomy was performed, and the histopathologic diagnosis was nephroblastoma. The dog did not receive any chemotherapy, and there was no evidence of recurrent disease or metastasis over 30 mo after nephrectomy. This is the first case report of a dog presenting with polyuria and polydipsia found to be a result of nephroblastoma. Furthermore, this is the longest survival reported for canine nephroblastoma treated with nephrectomy alone.

Published: August 2019

Este artigo apresenta resultados do projeto Atlas da Rede Estadual de Educação de São Paulo, discutindo a importância da análise espacial nas/das políticas educacionais. Para tanto, analisamos duas políticas educacionais implementadas pela Secretaria Estadual de Educação de São Paulo (SEE-SP), baseadas no princípio da Nova Gestão Pública. Trata-se do Programa de Ensino Integral (PEI), iniciado em 2012, e do Projeto de Reorganização Escolar, de 2015. Nesta análise, elaboramos uma série de mapas, espacializando as duas políticas no município de São Paulo, recorte investigativo desta pesquisa, que demonstram como estas têm ampliado as desigualdades espaciais e educacionais, na contramão da efetivação do direito à educação. Utilizando dados públicos, concluímos que, no caso da Reorganização Escolar, o argumento defendido pelo governo de decréscimo demográfico para o fechamento de escolas não se sustenta, uma vez que tal fenômeno não se converte automaticamente em diminuição de matrículas. Já sobre o Programa de Ensino Integral, reconhecemos que se baseia numa lógica insularizante, produzindo unidades escolares privilegiadas destinadas a alunos que moram nas regiões com as melhores condições estruturais da cidade. De forma geral, as análises apresentadas revelam a lógica de racionalização gerencial dos recursos da rede estadual de educação, que pouco dialoga com a desigualdade espacial da escola pública e do território paulistano. Nesse sentido, nota-se a permanência do abstracionismo pedagógico como norteadora das políticas educacionais no estado de São Paulo, sob a lógica da Nova Gestão Pública, em que as condições de desigualdade socioespacial encontradas na referida rede são pouco problematizadas pelas políticas educacionais propostas.
