A Model for Public Fast Charging Infrastructure Needs
Authors: Gnann Till , Goldbach Daniel , Jakobsson Niklas , Plötz Patrick , Bennehag Anders , Sprei Frances
Published: May 2018

Plug-in electric vehicles can reduce GHG emissions although the low availability of public charging infra-structure combined with short driving ranges prevents potential users from adoption. The rollout and opera-tion, especially of public fast charging infrastructure, is very costly. Therefore, policy makers, car manufac-turers and charging infrastructure providers are interested in determining a number of charging stations that is sufficient. Since most studies focus on the placement and not on the determination of the number of charging stations, this paper proposes a model for the quantification of public fast charging points. We first analyze a large database of German driving profiles to obtain the viable share of plug-in electric vehicles in 2030 and determine the corresponding demand for fast charging events. Special focus lies on a general formalism of a queuing system for charging points. This approach allows us to quantify the capac-ity provided per charging point and the required quantity. Furthermore, we take a closer look on the sto-chastic occupancy rate of charging points for a certain service level and the distribution of the time users have to wait in the queue. When applying this model to Germany, we find about 15,000 fast charging points with 50 kW necessary in 2030 or ten fast charging point per 1,000 BEVs. When compared with existing charging data from Sweden, this is lower than the currently existing 36 fast charging points per 1,000 BEVs. Furthermore, we compare the models output of charging event distribution over the day with that of the real data and find a qualitatively similar load of the charging network, though with a small shift towards later in the day for the model.
Electric Vehicle Dealership Education & Training
Authors: Karwa Manoj K.
Published: May 2018

A major hurdle in the adoption and optimization of electrical vehicles is the transfer of knowledge from the dealer to the consumer. The first point of contact for most electric vehicle consumers is the dealer sales staff. Often dealerships have high turnover in sales staff and are driven to annual, quarterly and monthly sales. The majority of dealerships’ focus is on closing new car sales, service and accessories. Leviton will share insights and best practices from the deployment of electrical vehicle supply equipment with four major automakers across nearly 3,000 dealerships in North America.
Comparative life cycle assessment of electric and conventional vehicles used in Québec, Canada
Authors: Roy Pierre-Olivier , Ménard Jean-François , Fallaha Sophie
Published: May 2018

This study evaluates the potential environmental benefits of using an electric over a conventional vehicle in the province of Québec, Canada; a province characterised with an electric grid mix mostly based on hydroelectricity. To do so, we applied an environmental life cycle assessment approach whose results suggest that use of the electric vehicle should be promoted in the province of Québec but only if the vehicle lifetime is optimised.
The World Electric Vehicle Journal, The Open Access Journal for the e-Mobility Scene
Authors: Van Mierlo Joeri
Published: May 2018

The World Electric Vehicle Journal is the first peer-reviewed international scientific journal that covers all studies related to battery, hybrid, and fuel cell electric vehicles comprehensively. The gaining interest in e-mobility and related fast developments in electric vehicles has been leading to the need for the academic and industrial world, as well as the societal stakeholders, to have their own open-access journal in which they can share the latest developments and knowledge about electric vehicles. The journal accepts papers from all different disciplines, from new battery technologies, over propulsion system, and charging infrastructure to market developments and consumer behaviour. The World Electric Vehicle Journal is the primary scientific journal serving the interests of the international electric vehicle community. The World Electric Vehicle Journal has been managed by the World Electric Vehicle Association for the 10 years, with support from the Vrije Universiteit Brussel, and we have decided to further improve our professional approach by setting up the cooperation with MDPI as our professional publisher. Do you want to be inspired by e-mobility? Read more in the article below.
ANALYZING THE RENT-TO-PRICE RATIO FOR THE HOUSING MARKET AT THE MICRO-SPATIAL SCALE
Authors: LEE Changro , PARK Keyho
Published: May 2018

The rent-to-price ratio is one of the popular indicators for monitoring the property market. This study explores micro-scale spatial dynamics of the ratio for houses at the individual property level in Seoul, South Korea. We match the apartment unit sold and the one leased based on the carefully chosen criteria and apply a Bayesian multi-level modeling approach to this matched dataset. We employ the Integrated Nested Laplace Approximations (INLA) algorithm in order to estimate relevant parameters in the multi-level model. The ratio determinants found in the study include property age, apartment unit area, interest rate, and floor. This study also presents the importance of taking into account the hierarchical structure of apartment units, as well as seasonal and spatial variations when estimating the ratio and predicting future trends in the property market based on the ratio.
IMPACT OF INFILL DEVELOPMENT ON PRICES OF EXISTING APARTMENTS IN FINNISH URBAN NEIGHBOURHOODS
Authors: AHVENNIEMI Hannele , PENNANEN Kyösti , KNUUTI Antti , ARVOLA Anne , VIITANEN Kauko
Published: May 2018

Popularity of infill development is increasing because of the environmental benefits and cost saving potential it provides, which relate to the possibility to use existing infrastructure and services. However, the impact of infill development on value of existing properties has not been studied to a sufficient extent. Therefore, the aim of our study is to analyse whether infill development affects the prices of existing apartments. We carried out statistical analysis based on data from seven case neighbourhoods, and prices of more than 6000 housing transactions from one decade. The results of our analysis do not support the hypothesis of infill development affecting positively existing housing prices, but neither did the study show a significant negative effect. Both amenity effect and negative externalities may provide explanations as to why property values do not change due to infill development.

Published: May 2018

We present new observations from 2016 of two Jupiter Trojan asteroids that are targets for the Lucy Discovery mission. The extremely long rotation period of (11351) Leucus is confirmed and refined to a secure value of 445.732 ± 0.021 hr with photometric parameters of H

r
 = 11.046 ± 0.003 and G

r
 = 0.58 ± 0.02 in the SDSS r′ filter. This leads to a geometric albedo of p

V
 = 4.7%. The amplitude of the light curve was measured to be 0.61 mag, unchanged from the value of one-fourth of a revolution earlier, suggesting a low obliquity. The first light-curve observations for (15094) Polymele are also presented. This object is revealed to have a much shorter rotation period of 5.8607 ± 0.0005 hr with a very low amplitude of 0.09 mag. Its photometric parameters are H

r
 = 11.691 ± 0.002 and G

r
 = 0.22 ± 0.02. These values lead to a refined geometric albedo of p

V
 = 7.3%. This object is either nearly spherical or was being viewed nearly pole-on in 2016. Further observations are required to fully determine the spin pole orientation and convex-hull shapes.

Published: May 2018

We present Atacama Large Millimeter/Sub-Millimeter Array (ALMA) Band 6 observations of a complete sample of protoplanetary disks in the young (∼1–3 Myr) Lupus star-forming region, covering the 1.33 mm continuum and the 12CO, 13CO, and C18O J = 2–1 lines. The spatial resolution is ∼0.″25 with a medium 3σ continuum sensitivity of 0.30 mJy, corresponding to M
dust ∼ 0.2 M
⊕. We apply Keplerian masking to enhance the signal-to-noise ratios of our 12CO zero-moment maps, enabling measurements of gas disk radii for 22 Lupus disks; we find that gas disks are universally larger than millimeter dust disks by a factor of two on average, likely due to a combination of the optically thick gas emission and the growth and inward drift of the dust. Using the gas disk radii, we calculate the dimensionless viscosity parameter, α
visc, finding a broad distribution and no correlations with other disk or stellar parameters, suggesting that viscous processes have not yet established quasi-steady states in Lupus disks. By combining our 1.33 mm continuum fluxes with our previous 890 μm continuum observations, we also calculate the millimeter spectral index, α
mm, for 70 Lupus disks; we find an anticorrelation between α
mm and millimeter flux for low-mass disks (M
dust ≲ 5), followed by a flattening as disks approach α
mm ≈ 2, which could indicate faster grain growth in higher-mass disks, but may also reflect their larger optically thick components. In sum, this work demonstrates the continuous stream of new insights into disk evolution and planet formation that can be gleaned from unbiased ALMA disk surveys.
Spectral Study of A1Π–X1Σ+ Transitions of CO Relevant to Interstellar Clouds
Authors: Cheng Junxia , Zhang Hong , Cheng Xinlu
Published: May 2018

Highly correlated ab initio calculations were performed for an accurate determination of the A
1Π–X
1Σ+ system of the CO molecule. A highly accurate multi-reference configuration interaction approach was used to investigate the potential energy curves (PECs) and the transition dipole moment curve (TDMC). The resultant PECs and TDMC found by using the aug-cc-pV5Z (aV5Z) basis set and 5330 active spaces are in good agreement with the experimental data. Moreover, the Einstein A coefficients, lifetimes, ro-vibrational intensities, absorption oscillator strengths, and integrated cross sections are calculated so that the vibrational bands include v″ = 0–39 

 v′ = 0–23. For applications in the atmosphere and interstellar clouds, we studied the transition lineshapes to Gaussian and Lorentzian profiles at different temperatures and pressures. The intensities were calculated at high temperature that was used to satisfy some astrophysical applications, such as in planetary atmospheres. The results are potentially useful for important SAO/NASA Astrophysics Data System and databases such as HITRAN, HITEMP, and the National Institute of Standards and Technology. Because the results from many laboratory techniques and our calculations now agree, analyses of interstellar CO based on absorption from A
1Π–X
1Σ+ are no longer hindered by present spectral parameters.
The Parallax of the Red Hypergiant VX Sgr with Accurate Tropospheric Delay Calibration
Authors: Xu 徐双 Shuangjing 敬 , Zhang 张 Bo 波 , Reid Mark J. , Menten Karl M. , Zheng 郑兴 Xingwu 武 , Wang 王广 Guangli 利
Published: May 2018

We report astrometric results of VLBI phase-referencing observations of 22 GHz H2O masers emission toward the red hypergiant VX Sgr, one of most massive and luminous red hypergiant stars in our Galaxy, using the Very Long Baseline Array. A background source, J1820−2528, projected 4.°4 from the target VX Sgr, was used as the phase reference. For the low decl. of these sources, such a large separation normally would seriously degrade the relative astrometry. We use a two-step method of tropospheric delay calibration, which combines the VLBI geodetic-block (or Global Positioning System) calibration with an image-optimization calibration, to obtain a trigonometric parallax of 0.64 ± 0.04 mas, corresponding to a distance of

kpc. The measured proper motion of VX Sgr is 0.36 ± 0.76 and −2.92 ± 0.78 mas yr−1 in the eastward and northward directions. The parallax and proper motion confirms that VX Sgr belong to the Sgr OB1 association. Rescaling bolometric luminosities in the literature to our parallax distance, we find that the luminosity of VX Sgr is (1.95 ± 0.62) × 105
L
⊙, where the uncertainty is dominated by differing photometry measurements.
Simultaneous Survey of Water and Class I Methanol Masers toward Red MSX Sources
Authors: Kim Chang-Hee , Kim Kee-Tae , Park Yong-Sun
Published: May 2018

We report simultaneous single-dish surveys of 22 GHz H2O and 44 and 95 GHz class I CH3OH masers toward 299 Red Midcourse Space Experiment Sources in the protostellar stage. The detection rates are 45% at 22 GHz, 28% at 44 GHz, and 23% at 95 GHz. There are 15, 53, and 51 new discoveries at 22, 44, and 95 GHz, respectively. We detect high-velocity (>30 km s−1) features in 27 H2O maser sources. The 95 GHz maser emission is detected only in 44 GHz maser sources. The two transitions show strong correlations in the peak velocity, peak flux density, and isotropic maser luminosity, indicating that they are likely generated in the same sites by the same mechanisms. The 44 GHz masers have much narrower distributions than 22 GHz masers in the relative peak velocity and velocity range, while 6.7 GHz class II CH3OH masers have distributions intermediate between the two. The maser luminosity significantly correlates with the parental clump mass, while it correlates well with the bolometric luminosity of the central protostar only when data of the low-mass regime from the literature are added. Comparison with the results of previous maser surveys toward massive star-forming regions suggests that the detection rates of 22 and 44 GHz masers tend to increase as the central objects evolve. This is contrary to the trends found in low- and intermediate-mass star-forming regions. Thus, the occurrence of both masers might depend on the surrounding environments as well as on the evolution of the central object.

We present the first results from a new, high-resolution 12CO(1–0), 13CO(1–0), and C18O(1–0) molecular-line survey of the Orion A cloud, hereafter referred to as the CARMA-NRO Orion Survey. CARMA observations have been combined with single-dish data from the Nobeyama 45 m telescope to provide extended images at about 0.01 pc resolution, with a dynamic range of approximately 1200 in spatial scale. Here we describe the practical details of the data combination in uv space, including flux scale matching, the conversion of single-dish data to visibilities, and joint deconvolution of single-dish and interferometric data. A Δ-variance analysis indicates that no artifacts are caused by combining data from the two instruments. Initial analysis of the data cubes, including moment maps, average spectra, channel maps, position–velocity diagrams, excitation temperature, column density, and line ratio maps, provides evidence of complex and interesting structures such as filaments, bipolar outflows, shells, bubbles, and photo-eroded pillars. The implications for star formation processes are profound, and follow-up scientific studies by the CARMA-NRO Orion team are now underway. We plan to make all the data products described here generally accessible; some are already available at https://dataverse.harvard.edu/dataverse/CARMA-NRO-Orion.
Kinetic Properties of an Interplanetary Shock Propagating inside a Coronal Mass Ejection
Authors: Liu Mingzhe , Liu Ying D. , Yang Zhongwei , Wilson L. B. , Hu Huidong
Published: May 2018

We investigate the kinetic properties of a typical fast-mode shock inside an interplanetary coronal mass ejection (ICME) observed on 1998 August 6 at 1 au, including particle distributions and wave analysis with the in situ measurements from Wind. Key results are obtained concerning the shock and the shock–ICME interaction at kinetic scales: (1) gyrating ions, which may provide energy dissipation at the shock in addition to wave-particle interactions, are observed around the shock ramp; (2) despite the enhanced proton temperature anisotropy of the shocked plasma, the low plasma β inside the ICME constrains the shocked plasma under the thresholds of the ion cyclotron and mirror-mode instabilities; (3) whistler heat flux instabilities, which can pitch-angle scatter halo electrons through a cyclotron resonance, are observed around the shock, and can explain the disappearance of bi-directional electrons (BDEs) inside the ICME together with normal betatron acceleration; (4) whistler waves near the shock are likely associated with the whistler heat flux instabilities excited at the shock ramp, which is consistent with the result that the waves may originate from the shock ramp; (5) the whistlers share a similar characteristic with the shocklet whistlers observed by Wilson et al., providing possible evidence that the shock is decaying because of the strong magnetic field inside the ICME.
The Effect of Oxygen on Organic Haze Properties
Authors: Ugelow Melissa S. , Haan David O. De , Hörst Sarah M. , Tolbert Margaret A.
Published: May 2018

Atmospheric organic hazes are present on many planetary bodies, possibly including the ancient Earth and exoplanets, and can greatly influence surface and atmospheric properties. Here we examine the physical and optical properties of organic hazes produced with molecular nitrogen, methane, carbon dioxide, and increasing amounts of molecular oxygen, and compare them to hazes produced without added oxygen. As molecular oxygen is included in increasing amounts from 0 to 200 ppmv, the mass loading of haze produced decreases nonlinearly. With 200 ppmv molecular oxygen, the mass loading of particles produced is on the order of the amount of organic aerosol in modern Earth’s atmosphere, suggesting that while not a thick organic haze, haze particles produced with 200 ppmv molecular oxygen could still influence planetary climates. Additionally, the hazes produced with increasing amounts of oxygen become increasingly oxidized and the densities increase. For hazes produced with 0, 2 and 20 ppmv oxygen, the densities were found to be 0.94, 1.03 and 1.12 g cm−3, respectively. Moreover, the hazes produced with 0, 2, and 20 ppmv oxygen are found to have real refractive indices of n = 1.58 ± 0.04, 1.53 ± 0.03 and 1.67 ± 0.03, respectively, and imaginary refractive indices of

, 0.002 ± 0.002 and

, respectively. These k values demonstrate that the particles formed with oxygen have no absorption within our experimental error, and could result in a light scattering layer in an oxygen-containing atmosphere.
A fork in the alphabet soup: DoeDat a multilingual crowdsourcing platform
Authors: Groom Quentin , Bogaerts Ann , Veríssimo Pereira Nuno , De Smedt Sofie
Published: May 2018

Specimen labels are written in numerous languages and accurate interpretation requires local knowledge of place names, vernacular names and people’s names. In many countries more than one language is in common usage. Belgium, for example, has three official languages. Crowdsourcing has helped many collections digitize their labels and generates useful data for science. Furthermore, direct engagement of the public with a herbarium increases the collection’s visibility and potentially reinforces a sense of common ownership. For these reasons we built DoeDat, a multilingual crowdsourcing platform forked from Digivol of the Australian Museum (Figs 1, 2). Some of the useful features we inherited from Digivol include a georeferencing tool, configurable templates, simple project management and individual institutional branding.

Running a multilingual website does increase the work needed to setup and manage projects, but we hope to gain from the broader engagement we can attract. Currently, we are focusing our work on Belgian collections were Dutch and French are the primary languages, but in the future we may expand our languages when we work on our international collections. We also hope that we can eventually merge our code with that of Digivol, so that we can both benefit from each other's developments.
An automated device for the digitization and 3D modelling of insects, combining extended-depth-of-field and all-side multi-view imaging
Authors: Ströbel Bernhard , Schmelzle Sebastian , Blüthgen Nico , Heethoff Michael
Published: May 2018

Digitization of natural history collections is a major challenge in archiving biodiversity. In recent years, several approaches have emerged, allowing either automated digitization, extended depth of field (EDOF) or multi-view imaging of insects. Here, we present DISC3D: a new digitization device for pinned insects and other small objects that combines all these aspects. A PC and a microcontroller board control the device. It features a sample holder on a motorized two-axis gimbal, allowing the specimens to be imaged from virtually any view. Ambient, mostly reflection-free illumination is ascertained by two LED-stripes circularly installed in two hemispherical white-coated domes (front-light and back-light). The device is equipped with an industrial camera and a compact macro lens, mounted on a motorized macro rail. EDOF images are calculated from an image stack using a novel calibrated scaling algorithm that meets the requirements of the pinhole camera model (a unique central perspective). The images can be used to generate a calibrated and real color texturized 3Dmodel by ‘structure from motion’ with a visibility consistent mesh generation. Such models are ideal for obtaining morphometric measurement data in 1D, 2D and 3D, thereby opening new opportunities for trait-based research in taxonomy, phylogeny, eco-physiology, and functional ecology.

Published: May 2018

Limited evidence is available regarding the correlation between intraoperative hypothermia and perioperative complications in shoulder arthroplasty. The purpose of this study was to determine the incidence of intraoperative hypothermia in patients treated with shoulder arthroplasty and its effect on perioperative complications. A retrospective chart review was performed on 657 consecutive patients who underwent shoulder arthroplasty at a single institution between August 2013 and June 2016. Demographic data, surgery-specific data, postoperative complications, length of stay, and 30-day read-mission were recorded. Patients were classified as hypothermic if their mean intraoperative temperature was less than 36°C. Statistical analyses with univariate and multivariate logistic regression were performed to evaluate the association of intraoperative hypothermia with perioperative complications. The incidence of intraoperative hypothermia in shoulder arthroplasty was 52.7%. Increasing age (
P
=.002), lower body mass index (
P
=.006), interscalene anesthetic (
P
=.004), and lower white blood cell count (
P
<.001) demonstrated increased association with hypothermia. Longer operating room times and increased estimated blood loss were not found to be associated with intraoperative hypothermia. Hypothermia demonstrated no significant association with surgical site infections nor any other perioperative complications. Patients undergoing shoulder arthroplasty showed a high incidence of intraoperative hypothermia. Lower body mass index, increasing age, interscalene anesthetic, and lower white blood cell count were associated with an increased incidence of hypothermia. Contrary to previous studies, intraoperative hypothermia was not found to contribute to perioperative complications in shoulder arthroplasty. [

Published: May 2018

The Patient Protection and Affordable Care Act expanded health coverage for low-earning individuals and families. With more Americans having access to care, the use of elective procedures, such as total hip arthroplasty (THA), was expected to increase. Therefore, the aim of this study was to evaluate trends in THA before and after the initiation of the Patient Protection and Affordable Care Act regarding race, age, body mass index, and sex between 2008 and 2015. The National Surgical Quality Improvement Program database was queried for all individuals who had undergone primary THA between 2008 and 2015. This yielded a total of 104,209 patients. Descriptive statistics were used to analyze patient-level data. A Cochran–Armitage test assessed trends in categorical data points over time. Analysis indicated an increased percentage of blacks or African Americans undergoing THA (7.8% vs 9.2%,
P
<.001), followed by Native Americans or Pacific Islanders (0.0% vs 0.4%,
P
<.001), American Indians or Alaskan Natives (0.3% vs 0.5%,
P

P
=.002). An increased percentage of patients 55 to 80 years old received THAs (68.6% vs 74.1%,
P

Furthermore, these findings may inform health policy makers interested in increasing access to procedures underutilized by specific patient populations and the creation of strategies to meet increased demand.

OCT Angiography Helps Distinguish Between Proliferative Macular Telangiectasia Type 2 and Neovascular Age-Related Macular Degeneration
Authors: Zheng Fang , Motulsky Elie H. , de Oliveira Dias João Rafael , de López Edith Pérez , Gregori Giovanni , Rosenfeld Philip J.
Published: May 2018

BACKGROUND AND OBJECTIVE:

To demonstrate the advantage of optical coherence tomography angiography (OCTA) for the diagnosis and management of proliferative macular telangiectasia type 2 (MacTel2) masquerading as neovascular age-related macular degeneration (AMD).

PATIENTS AND METHODS:

This is an observational cases series. Three patients referred with the diagnosis of neovascular AMD were identified in this retrospective study. In addition to color fundus, fluorescein angiography, and spectral-domain OCT (SD-OCT) imaging, SD-OCTA (AngioPlex; Carl Zeiss Meditec, Dublin, CA) was performed.

RESULTS:

SD-OCTA revealed bilateral parafoveal retinal microvascular changes in three patients and unambiguously confirmed the diagnosis of MacTel2.

CONCLUSION:

OCTA is an important tool for the correct diagnosis of MacTel2 in older patients with the concomitant or masquerading diagnosis of AMD.

Mild Bilateral Hemorrhagic Occlusive Retinal Vasculitis Following Intracameral Vancomycin Administration in Cataract Surgery
Authors: Arepalli Sruthi , Modi Yasha S. , Deasy Ryan , Srivastava Sunil K.
Published: May 2018

A patient underwent cataract surgery with prophylactic intracameral vancomycin (Vancocin; Pfizer, New York City, NY) in each eye, 2 weeks apart. Four weeks after, the patient presented with a mild bilateral hemorrhagic occlusive retinal vasculitis (HORV). A systemic work-up was negative for syphilis, toxoplasmosis,
Bartonella
, tuberculosis, and sarcoidosis. The patient was treated with oral steroids and one intravitreal steroid injection in the left eye. Ten months after presentation, the patient's vasculitis was quiescent. Although the literature describes primarily severe forms of HORV, the authors' case describes bilateral, mild HORV and highlights the potential underreporting of these cases in the literature.

Efficiency of self-healing cementitious materials with encapsulated polyurethane to reduce water ingress through cracks
Authors: Van Belleghem B. , Van Tittelboom K. , De Belie N.
Published: May 2018

Cracks in reinforced concrete elements can cause major durability issues due do the accelerated ingress of aggressive substances. In this study, repair of cracks was addressed by incorporating encapsulated polyurethane based healing agents in the cementitious material as an autonomous healing mechanism.

Capillary sorption tests showed that a high viscosity healing agent could reduce the water ingress in cracked mortar, but a large scatter in the results was found, resulting in a large range of healing efficiencies (18 – 108%). The low viscosity polyurethane showed a more complete and consistent crack healing. Healing efficiencies ranging from 95 to 124% were observed (crack width up to 295 μm). The proposed healing mechanism is very effective in blocking the ingress of water. This will enhance the durability of cementitious materials and consequently extend their lifetime.
« Retoucher cette pièce dans le goût d’autrefois » : pourquoi Mallarmé a-t-il réécrit « Le Guignon » ?
Authors: Dominicy Marc
Published: May 2018

Pour le « Guignon », les versions destinées à la publication se répartissent en trois strates. Du premier état, seuls les vers 1 à 15 furent imprimés en 1862 ; Mallarmé n’ayant pu approuver cette mutilation, on prendra en compte le texte complet d’après le manuscrit qui servit de base à la publication. Viennent ensuite la version des Poètes maudits (1883-1884) et l’état définitif que livrent l’édition photolithographiée (1887), un programme du Théâtre d’art (1891) et la maquette de 1894 utilisée pour l’édition Deman (1899). En confrontant l’état définitif au texte des Poètes maudits et aux variantes significatives de 1862, on constate qu’en 1887, Mallarmé infléchit la composante « grotesque » du poème vers l’érotisme et la scatologie, laïcise les sources religieuses dont se nourrissaient Les Fleurs du mal, et dote son propos d’une dimension sociopolitique. Ce tournant, qui caractérise plusieurs textes postérieurs à 1884, montre que Mallarmé veut alors se construire un nouvel éthos.

Diante dos desafios educacionais, das mudanças sociais e legais voltadas à inclusão social, este artigo tem por objetivo apresentar os resultados obtidos na pesquisa de mestrado em Educação, que analisou o processo de inclusão educacional de pessoas com deficiência visual nos cursos de educação superior a distância no Brasil, por meio do uso das TDIC e da tecnologia assistiva. A pesquisa propôs-se a analisar 12 artigos a partir de cinco categorias de análises pré-definidas: contribuições da EaD para os estudantes com deficiência visual; mediação por meio das tecnologias digitais de informação e comunicação e tecnologia assistiva; fragilidade da relação educação a distância e estudante com deficiência visual; desafios da prática pedagógica e do processo de aprendizagem; efetivação da inclusão educacional. Os resultados mostraram que os estudos sobre o assunto ainda são recentes, mas as pesquisas existentes afirmam que a educação a distância contribui com a inclusão educacional desses estudantes, uma vez que proporciona o acesso a uma educação de qualidade e garante aos estudantes os direitos previstos em lei. Os principais desafios são a mediação do professor, sua formação, a acessibilidade dos ambientes virtuais de aprendizagem e o domínio do uso das tecnologias por parte de professores e estudantes.
As representações sociais na construção da identidade profissional e do trabalho docente
Authors: Gebran Raimunda Abou , Trevizan Zizi
Published: May 2018

O objetivo desse artigo é partilhar do debate acadêmico sobre os modos de construção da identidade profissional dos docentes da Educação Básica e suas representações sociais sobre a profissão. Foi utilizada a metodologia de pesquisa qualitativa com entrevista semiestruturada, envolvendo 19 professores de uma escola de Educação Básica do interior paulista. Os dados geraram três categorias de análise: a identidade e a atuação profissional dos professores e suas representações sobre a profissão docente; a construção da autonomia com vistas à efetivação de práticas educativas emancipatórias; e o senso crítico-ideológico do professor em seu contexto de atuação. O aporte epistemológico centrou-se nos estudos sobre representações sociais e profissionalização docente. Os resultados confirmaram que as estruturas sociais e culturais, historicamente constituídas, foram determinantes na construção da identidade profissional dos sujeitos da pesquisa e de suas representações sociais sobre a profissão.

A Educação Física do tempo do ‘pensado’ ao tempo do ‘vivido’: um estudo empírico/exploratório sobre representações e práticas docentes
Authors: Rodrigues Lucinda Da Conceição Rebelo , Cunha António Camilo Teles Nascimento , Moreira Evando Carlos
Published: May 2018

Este artigo tem por objetivo conhecer as representações e práticas dos professores de Educação Física, a lecionar em diferentes ciclos de ensino, relativamente ao movimento a partir do binômio ‘pensado’ (o movimento estruturado no currículo) e ‘vivido’ (aquele que é informal, não formal, de intencionalidade fenomenológica). Para isso, foram tomadas como referência dois paradigmas de abordagem do currículo e das práticas: A ‘Educação Física pensada’ – do currículo formal; e a Educação Física – a que vamos chamar de ‘vivida’ – vivida pelo ato espontâneo do brincar, do jogar, do experimentar, do contexto, da circunstância. O grupo (amostra) de estudo foi constituído por 10 professoras (5 do 2º ciclo e 5 do 3º ciclo). Para a coleta de dados foi utilizada uma entrevista semiestruturada, sendo depois feita uma análise qualitativa/conteúdo aos dados. Os resultados revelam visões similares e complementares sobre a problemática.

Authors: Backes José Licínio
Published: May 2018

O artigo objetiva contribuir para o debate sobre o sentido do ensino médio para as juventudes no contexto atual. Para tanto apresenta as tensões e disputas históricas e as mais recentes em torno do ensino médio e as articula com os resultados de uma pesquisa de campo realizada com jovens do ensino médio de uma escola particular reconhecida como sendo de qualidade. Com base nos autores utilizados e na pesquisa efetuada, questiona a qualidade do ensino médio particular e argumenta que tanto ela quanto o sentido que este possui, ainda que fossem universalizados, não serviriam para a construção de uma sociedade mais justa e igualitária.
Energetic Analysis using theoretical modeling and the characteristic equation method in a small absorption chiller with LiBr/H2O
Authors: Villa Alvaro Antonio Ochoa , Costa José Ângelo Peixoto da , Santos Carlos Antonio Cabral dos
Published: May 2018

This paper sets out to examine a small absorption chiller that uses the pair LiBr/ H2O with a 4.5 kW nominal capacity, using theoretical modeling and the characteristic equation method. The idea is to compare two ways of simulating and evaluating absorption systems by analyzing the temperatures and flow rates of external hot, chilled and cold water circuits, as well as the values of the overall heat transfer coefficients of each component. Energetic analysis is based on conserving mass and energy by taking into consideration the overall heat transfer coefficients and their respective areas via the UA products of the 5 components of the absorption chiller. The characteristic equation method is based on Duhring’s rule of the internal temperature which is founded on saturation mean temperatures and the Duhring coefficient (B). The results of comparing the activation of thermal power and the cooling capacity of the Rotartica absorption chiller, obtained by theoretical modeling and from the characteristic equation values, were good since the mean relative errors found were 4% lower for most of the operating conditions examined.
Enhancing Soil Science Education with a Graphic Syllabus
Authors: Mikhailova E. A.
Published: May 2018

Core Ideas

The graphic syllabus can be an addition to the traditional course syllabus.

The graphic syllabus enables students to visualize the “big picture” of the course.

Most students preferred graphic syllabus in addition to traditional one.

A graphic syllabus that enables students to visualize the “big picture” of the soil science course can be an addition to the traditional course syllabus. The purpose of this study was to develop the graphic syllabus and test it in an introductory soil science course. The graphic syllabus was based on the principles of “parallel” teaching/learning and storytelling. It was created by dividing the course into three units: (1) Soil ABC's, (2) Soil properties, and (3) Soil fertility and management. Each unit contains a set of soil orders with a list of corresponding state/representative soils in the United States. Clemson University students from various fields (forestry, wildlife biology, and environmental science) compared traditional and graphic syllabi. Students were asked to complete a survey consisting of questions related to their opinions of traditional and graphic syllabi. Responses to the survey questions indicated that most students were juniors and almost never experienced (97%) graphic syllabi in their college courses. Most students preferred the graphic syllabus in addition to a traditional one. Students reported that the graphic syllabus helped them better understand the course structure and was more exciting and easier to view on cell phones. Although the use of a graphic syllabus is usually limited to introductory courses, it can also be adapted to upper‐level soil science courses. This article offers an organizational strategy for expediting the graphic syllabus design.
A novel method for the extraction of local gravity wave parameters from gridded three-dimensional data: description, validation, and application
Authors: Schoon Lena , Zülicke Christoph
Published: May 2018

Abstract. For the local diagnosis of wave properties, we develop, validate, and apply a novel method which is based on the Hilbert transform. It is called Unified Wave Diagnostics (UWaDi). It provides the wave amplitude and three-dimensional wave number at any grid point for gridded three-dimensional data. UWaDi is validated for a synthetic test case comprising two different wave packets. In comparison with other methods, the performance of UWaDi is very good with respect to wave properties and their location. For a first practical application of UWaDi, a minor sudden stratospheric warming on 30 January 2016 is chosen. Specifying the diagnostics for hydrostatic inertia–gravity waves in analyses from the European Centre for Medium-Range Weather Forecasts, we detect the local occurrence of gravity waves throughout the middle atmosphere. The local wave characteristics are discussed in terms of vertical propagation using the diagnosed local amplitudes and wave numbers. We also note some hints on local inertia–gravity wave generation by the stratospheric jet from the detection of shallow slow waves in the vicinity of its exit region.

Published: May 2018

Abstract. A short, but severe, wildfire smoke episode in July 2015, with an aerosol optical depth (AOD) approaching nine, had a significant impact on air quality, radiation and energy budgets across four land use types, and elicited a clear ecosystem response with respect to carbon fluxes at a bog and a forested site. Greatest impacts on radiation and energy budgets were observed at the forested site where the role of canopy architecture, and the complex physiological responses to an increase in diffuse radiation were most important. With widespread standing water, and little physiological control on evapotranspiration, the impacts on the partitioning of turbulent fluxes were modest at the bog compared to the physiologically dominated fluxes at the forested site. Despite the short duration and singular nature of the event, there was evidence of a diffuse radiation fertilization effect when AOD was less than two. With lighter smoke, both the wetland and forested site appeared to show enhanced photosynthetic activity (a greater sink for carbon-dioxide). However, with dense smoke the forested site became a strong source. Given the extensive forest cover in the Pacific Northwest and the growing importance of forest fires in the region, these results suggest that wildfire aerosol during the growing season potentially plays an important role in the regional ecosystem response to smoke and ultimately the carbon budget of the region.

Abstract. In the framework of the European FP7 project ECLAIRE a joint field campaign was run in Marmirolo, in the northern part of the Italy, one of the most polluted areas in Europe due to intense industrial activities and peculiar climate conditions promoting high ozone formation by photochemical reactions involving nitrogen oxides (NOx) and volatile organic compounds. The studied ecosystem is a mixed oak-hornbeam forest and the aim of this field campaign was to investigate the processes regulating the gas exchange between the forest and the atmosphere with a focus on ozone flux measurements and the interaction with reactive gases. Measurements were run on a 40 m tower equipped with sonic anemometers and fast ozone analyzers for eddy covariance at five different heights: one at canopy height, two above canopy and two below canopy. NO fluxes were measured above canopy and NOx fluxes were measured with a dynamic chamber system at the soil level. Ozone fluxes measured at different levels above the canopy showed a good agreement between each other, while fluxes at 24 m were surprisingly higher than the above ones. In this paper we discuss the possible reasons for this discrepancies shedding light on the role of NOx and of the coupling between forest and atmosphere will be explained. A partition of the ozone fluxes will be shown too to identify the most relevant sinks in the soil-plant continuum.
A middle latitude Rayleigh-scatter lidar temperature climatology determined using an optimal estimation method
Authors: Jalali Ali , Sica Robert J. , Haefele Alexander
Published: May 2018

Abstract. Hauchecorne and Chanin (1980) developed a robust method to calculate middle atmosphere temperature profiles using measurements from Rayleigh-scatter lidars. This traditional method has been successfully used to greatly improve our understanding of middle atmospheric dynamics, but the method has some shortcomings in regard to the calculation of systematic uncertainties and vertical resolution of the retrieval. Sica and Haefele (2015) have shown the Optimal Estimation Method (OEM) addresses these shortcomings and allows temperatures to be retrieved with confidence over a greater range of heights than the traditional method. We have developed a temperature climatology from Purple Crow Lidar (PCL) Rayleigh-scatter measurements on 519 nights using an OEM. Our OEM retrieval is a first-principle retrieval where the forward model is the lidar equation and the measurements are the level 0 count returns. It includes a quantitative determination of the top altitude of the retrieval, the evaluation of 9 systematic plus random uncertainties, and vertical resolution of the retrieval on a profile-by-profile basis. By using the calculated averaging kernels our new retrieval extends our original climatology by an additional 5 to 10 km in altitude relative to the traditional method. The OEM statistical uncertainty makes the largest contribution in the uncertainty budget. However, significant contributions are also made from the systematic uncertainties, in particular the uncertainty due to choosing a tie-on pressure as required by the assumption of hydrostatic equilibrium, mean molecular mass variations with height, and ozone absorption cross section uncertainty. The vertical resolution of the PCL climatology is 1 km up to about 90 km and then increases to about 3 km around 100 km. The new PCL temperature climatology is compared with three sodium lidar climatologies. The comparison between the PCL and sodium lidar climatologies shows improved agreement relative to the climatology generated using the method of Hauchecorne and Chanin, that is the PCL climatology is as similar to the sodium lidar climatologies as the sodium lidar climatologies are to each other. The height-extended OEM-derived climatology is highly insensitive to the choice of an a priori temperature profile, in the sense that the a priori temperature profile contributes much less uncertainty than the statistical uncertainty.
