Abstract
We present the first spatially resolved analysis of rest-frame optical and UV imaging and spectroscopy for a lensed galaxy at z = 2.39 hosting a Seyfert active galactic nucleus (AGN). Proximity to a natural guide star has enabled observations with high signal-to-noise ratio using Very Large Telescope SINFONI + adaptive optics (AO) of rest-frame optical diagnostic emission lines, which exhibit an underlying broad component with full width at half maximum ∼ 700 km s−1 in both the Balmer and forbidden lines. Measured line ratios place the outflow robustly in the region of the ionization diagnostic diagrams associated with AGNs. This unique opportunity—combining gravitational lensing, AO guiding, redshift, and AGN activity—allows for a magnified view of two main tracers of the physical conditions and structure of the interstellar medium in a star-forming galaxy hosting a weak AGN at Cosmic Noon. By analyzing the spatial extent and morphology of the Lyα and dust-corrected Hα emission, disentangling the effects of star formation and AGN ionization on each tracer, and comparing the AGN-induced mass outflow rate to the host star formation rate, we find that the AGN does not significantly impact the star formation within its host galaxy.
Evolution of the Coronal Cavity From the Quiescent to Eruptive Phase Associated with Coronal Mass Ejection

Abstract
We present the evolution of a coronal cavity encompassing its quiescent and eruptive phases in the lower corona. Using multiple vantage-point observations from the SDO/AIA, STEREO SECCHI/EUVI, and PROBA2/Sun Watcher with the APS and Image Processing (SWAP) extreme ultraviolet (EUV) imagers, we capture a sequence of quasi-static equilibria of the quiescent cavity, which exhibited a slow rise and an expansion phase during its passage on the solar disk from 2010 May 30 to June 13. By comparing the decay-index profiles of the cavity system during the different stages of its quiescent and pre-eruptive phases, we find that the decay-index value at the cavity centroid height can be used as a good indicator to predict the cavity eruption in the context of torus instability. Combining the observations of SWAP and the Large Angle and Spectrometric Coronagraph Experiment C2/C3, we show the evolution of the EUV cavity into the white-light cavity as a three-part structure of the associated coronal mass ejection that was observed to erupt on 2010 June 13. By applying successive geometrical fits to the cavity morphology, we find that the cavity exhibited non-self-similar expansion in the lower corona, below 2.2 ± 0.2 R
S, which points to the spatial scale for the radius of the source surface where the coronal magnetic field lines are believed to become radial. Furthermore, the kinematic study of the erupting cavity captures both the “impulsive” and “residual” phases of acceleration along with a strong deflection of the cavity at 1.3 R
S. We also discuss the role of driving forces behind the dynamics of the morphological and kinematic evolution of the cavity.
Atmospheres and UV Environments of Earth-like Planets throughout Post-main-sequence Evolution
Authors: Kozakis Thea , Kaltenegger Lisa 
Published: April 2019

Abstract
During the post-main-sequence (post-MS) phase of stellar evolution, the orbital distance of the habitable zone (HZ), which allows for liquid surface water on terrestrial planets, moves out past the system’s original frost line, providing an opportunity for outer planetary system surface habitability. We use a 1D coupled climate/photochemistry code to study the impact of the stellar environment on the planetary atmospheres of Earth-like planets/moons throughout its time in the post-MS HZ. We also explore the ground UV environments of such planets/moons and compare them to Earth’s. We model the evolution of star–planet systems with host stars ranging from 1.0 to 3.5 M
⊙ throughout the post-MS, calculating stellar mass loss and its effects on planetary orbital evolution and atmospheric erosion. The maximum amount of time a rocky planet can spend continuously in the evolving post-MS HZ ranges between 56 and 257 Myr for our grid stars. Thus, during the post-MS evolution of their host star, subsurface life on cold planets and moons could become remotely detectable once the initially frozen surface melts. Frozen planets or moons, like Europa in our solar system, experience a relatively stable environment on the horizontal branch of their host star’s evolution for millions of years.

La pratique de la récupération alimentaire en milieu urbain (ou « freeganisme ») est l’occasion d’interactions et d’échanges avec les passants, les commerçants, les travailleurs des déchets ou les récupérateurs. Portant un regard autoethnographique sur six années de pratique régulière de la récupération alimentaire dans les rues parisiennes, l’auteure propose d’étudier ce que ces interactions parfois conflictuelles nous disent du statut ambigu du déchet, de la récupération et du corps féminin aujourd’hui.
Penser la cueillette de plantes médicinales sauvages dans des sociétés en transition : le cas guyanais

Published: April 2019

La cueillette des plantes médicinales en Guyane française est une pratique relativement méconnue, sous-estimée et souvent perçue comme anecdotique ou insignifiante. Pourtant, tous les jours, des personnes peuvent être vues ramassant des plantes sur les bords de route, pour leur propre usage ou, dans de moindres proportions, pour les vendre. Cet article vise à caractériser ces pratiques de cueillette des plantes médicinales et leur diversité et à souligner la pertinence de l’entrée par ces plantes pour interroger le fonctionnement de sociétés sujettes à des transformations rapides et désignées ici comme « en transition ». À la lumière de deux études de cas, une sur la cueillette urbaine dans l’agglomération de Cayenne et l’autre en zone rurale le long du bas-Maroni, cet article permet de repenser les relations nature-société-ville. En observant les spécificités socio-culturelles influençant les modalités de cueillette, il propose un schéma conceptuel de ces pratiques en mobilisant les idées d’hétérogénéité et de finalité comme concepts explicatifs.
L’intégration des cueilleurs de déchets latino-américains ou la création d’une nouvelle marge
Authors: Durand Mathieu , De Oliveira Neves Fabio 
Published: April 2019

Pendant des décennies, les villes latino-américaines ont lutté contre les récupérateurs informels de déchets, au titre de la priorisation du la sécurité sanitaire et de la logique hygiéniste. Aujourd’hui, les combats contre le gaspillage des ressources et contre la pauvreté aboutissent à la reconnaissance de l’activité des récupérateurs. Ces « cueilleurs » de déchets, agissant autrefois de façon autonome, sont aujourd’hui au cœur de l’action municipale du recyclage en Amérique Latine. Pour autant, les limites de ce modèle apparaissent rapidement. Partout où l’intégration des récupérateurs informels se stabilise, de nouvelles marges apparaissent et une compétition se met en place pour capter les gisements de déchets. Quelles relations se mettent alors en place entre les parties prenantes ? Le Pérou, la Colombie et le Brésil permettront d’illustrer cette question.

L’engouement pour les produits naturels redynamise à l’échelle mondiale les cueillettes commerciales de plantes sauvages. En France métropolitaine, cette activité a longtemps été perçue comme marginale alors que plus de 10 % de la biodiversité végétale serait aujourd’hui concernée par cette économie du « sauvage ». Soucieux de se distancier des « pillages » qui agitent parfois les territoires ruraux et d’assurer la préservation des ressources végétales, des cueilleuses et des cueilleurs se sont réunis en 2011 au sein de l’Association française des professionnels de la Cueillette de plantes sauvages (AFC). Ce jeune collectif souhaite faire reconnaître le métier dans sa diversité et construire une éthique de la cueillette en concertation avec les acteurs des filières utilisatrices d’ingrédients naturels et les gestionnaires de l’environnement. Des collaborations avec des acteurs des milieux de la recherche et de la conservation ont permis de faire émerger une dynamique participative et réflexive pour accompagner ce processus de professionnalisation et penser les modalités de sa réalisation. A travers ce dispositif, les membres de l’AFC vont mettre à l’épreuve leurs valeurs, leurs savoir-faire et leurs rapports à la plante. En nous appuyant sur ces expériences partagées, des prémices de l’association au projet FloreS, nous proposons de discuter du renouveau des cueillettes commerciales en France métropolitaine.
Valoriser l’écologie pour légitimer le paysage ?
Authors: Roussel Fabien 
Published: April 2019

Les pourtours végétalisés de l’agglomération parisienne – un temps concernés par un projet de ceinture verte – font l’objet de multiples aménagements « verts », d’échelles variables et mettant en valeur des enjeux écologiques. En croisant sources littéraires, analyses photographiques et croquis de paysage, l’article montre comment ces valeurs écologiques légitiment des valeurs paysagères. Celles-ci sont illustrées par les représentations des écrivains voyageurs, témoins d’un imaginaire urbain d’une nature champêtre. L’analyse de photographies montre que la valorisation écologique par les acteurs publics ne dépend pas que des caractéristiques floristico-écologiques des milieux mais aussi des usages et des pratiques. Pour finir, le croquis révèle la dimension paysagère de la végétation sur les pourtours de l’agglomération parisienne et permet d’éclairer sous un nouveau jour les intentions des acteurs publics dans des contextes territoriaux particuliers.
Prospective analysis of factors predicting feasibility & success of longitudinal intussusception vasoepididymostomy in men with idiopathic obstructive azoospermia
Authors: Tiwari Devi Prasad , Razik Abdul , Das Chandan J. , Kumar Rajeev 
Published: April 2019

Background & objectives:
Microsurgical reconstruction for idiopathic obstructive azoospermia is a challenging procedure, and selection of appropriate patients is important for successful outcomes. This prospective study was done to evaluate the ability of scrotal ultrasound measurements to predict the surgical feasibility and determine factors that could predict a patent anastomosis following vaso-epididymal anastomosis (VE) in men with idiopathic obstructive azoospermia.

Methods:
In this prospective study, men diagnosed with idiopathic obstructive azoospermia, scheduled for a longitudinal intussusception VE, underwent a scrotal ultrasound measurement of testicular and epididymal dimensions. During surgery, site and type of anastomosis, presence of sperms in the epididymal fluid and technical satisfaction with the anastomosis were recorded. All men where VE could be performed were followed up for appearance of sperms in the ejaculate. Ultrasound parameters were compared between men who had a VE versus those with negative exploration. Predictive factors were compared between men with or without a patent anastomosis.

Results:
Thirty four patients were included in the study conducted between September 2014 and August 2016 and a VE was possible in only 19 (55%) patients. Of these 19 patients, six had a patent anastomosis with one pregnancy. Preoperative ultrasound measurements could not identify patients where a VE could not be performed. Motile sperm in the epididymal fluid was the only significant predictor of a successful anastomosis.

Interpretation & conclusion:
Forty five per cent of men planned for a VE for idiopathic obstructive azoospermia could not undergo a reconstruction. Ultrasound assessment of testicular and epididymal dimensions could not predict the feasibility of performing a VE. The presence of motile sperms in the epididymal fluid was the only significant predictor of a patent VE in our study.
High degree of fluoroquinolone resistance among pulmonary tuberculosis patients in New Delhi, India
Authors: Sharma Rohini , Sharma Surendra Kumar , Singh Binit Kumar , Mittal Abhenil , Kumar Prahlad 
Published: April 2019

Background & objectives:
The fluoroquinolones (FQs) group of antibiotics is the backbone drugs for the management of drug-resistant tuberculosis (TB). In routine clinical practice, drug susceptibility testing (DST) for FQs is not performed, and the patients are empirically treated. A limited information exists regarding FQs resistance among pulmonary TB cases. The present study was conducted to determine the FQs resistance among drug sensitive and drug-resistant pulmonary TB patients in a tertiary care centre in north India.

Methods:
A total of 1619 sputum/smear-positive specimens of pulmonary TB patients were subjected to DST for first-line drugs (FLDs) and second-line drugs. In addition, FQs DST was also performed using automated Mycobacterial Growth Indicator Tube-960 liquid culture technique. The immuno-chromatographic assay was performed to distinguish Mycobacterium tuberculosis complex (MTBC) from non-MTBC.

Results:
Mycobacterium tuberculosis (Mtb) was isolated in 1499 sputum specimens; 1099 culture specimens were sensitive to FLDs, 249 grew as multidrug-resistant (MDR) Mtb and the remaining 151 isolates revealed any drug resistance to FLDs. While FQs monoresistance among the FLD sensitive isolates was 3.1 per cent (35/1099), 27.3 per cent (68/249) among MDR Mtb isolates had additional FQs resistance.

Interpretation & conclusions:
FQs resistance among drug sensitive and MDR Mtb isolates was high in Delhi, India. Based on these findings, it is recommended that the DST for FQs should be routinely performed to avoid further amplification of drug resistance.
A descriptive pilot study of mitochondrial mutations & clinical phenotype in fibromyalgia syndrome
Authors: Danda Sumita , Thomas Blessy Mariam , Paramasivam G. , Thomas Raji , Mathew John , Danda Debashish 
Published: April 2019

Background & objectives:
Fibromyalgia syndrome (FMS) is one of the most common chronic pain conditions of unknown aetiology. Mitochondrial dysfunction has been reported in FMS with some studies reporting the presence of mitochondrial mutation namely A3243G, which also causes mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes. This pilot study was conducted to assess this mutation and also detect large deletions in mitochondrial DNA (mtDNA) in patients with FMS.

Methods:
Thirty female patients with FMS participated and 30 matched controls were included. Genomic DNA was subjected to polymerase chain reaction (PCR) amplification using specific primers followed by restriction digestion with ApaI enzyme to detect the specific A3243G mtDNA mutation. Long-range PCR was done in two sets to detect the large deletions in the mtDNA. Biochemical parameters including thyroid-stimulating hormone and vitamin D levels were also looked at.

Results:
None of the patients were found to carry the common mutation or large deletions. Low vitamin D level was a common finding. Hypothyroidism was found in a few patients.

Interpretation & conclusions:
Although the common mutation or large mtDNA deletions were not detected in blood mtDNA in the FMS patients, mutations in the muscle and sequence variation in mtDNA remained a possibility. Future studies in both blood and muscle tissue including mtDNA sequencing are warranted in such patients to determine if a subset of FMS patients have mitochondrial myopathy.
Assessment of Left Ventricular Mechanical Dyssynchrony in Left Bundle Branch Block Patients with and Without Heart Failure by Tissue Doppler Imaging
Authors: Raut Sambhaji , Chavan Chandrakant , Phalgune Deepak 
Published: April 2019

Introduction:
Large number of patients with heart failure (HF) have left bundle branch block (LBBB). Most precise method for identification of intraventricular dyssynchrony is tissue Doppler imaging (TDI). Purpose of this research was to compare left ventricular (LV) mechanical dyssynchrony in LBBB patients with and without HF and to compare various methods of LV systolic dyssynchrony assessment by TDI.

Materials and Methods:
One hundred and sixteen patients with a diagnosis of LBBB were included in the study. All patients underwent conventional two-dimensional echocardiography for global LV function assessment. LV systolic dyssynchrony was measured by opposing wall delay, maximum delay, and Yu index. LBBB patients were grouped into four classes according to their LV function and the presence or absence of HF, normal LV function without HF (Group A), normal LV function with HF (Group B), LV dysfunction with HF (Group C), and LV dysfunction without HF (Group D).

Results:
LV systolic dyssynchrony was significantly higher (P <0.001) in Group C and D as compared to Group A and B. LV systolic dyssynchrony was significant higher in Group C and D as compared to Group A and B by using opposing wall delay (P <0.001), Yu index (P <0.001), and maximum delay (P <0.001) imaging criteria. Mean Yu index (P <0.001) and mean maximum delay (P <0.001) were significantly higher in Group C and D as compared to Group A and B.

Conclusions:
LV systolic dyssynchrony was more common in LBBB patients with LV dysfunction than those with normal LV function, irrespective of the presence or absence of HF.

O objetivo desse artigo foi o de analisar a prática pedagógica das aulas de tênis de um clube tradicional no ensino da modalidade, a partir do discurso e da prática de professores experientes na modalidade. Para isso, a pesquisa foi estruturada em três partes: aproximação com o campo de pesquisa, observações sistemáticas das aulas de tênis e entrevistas semiestruturadas com os professores. Constatou-se que as aulas de tênis possuem características tradicionais centradas no ensino do gesto técnico descontextualizado da situação de jogo, embora os professores tenham esboçado no nível do discurso algumas compreensões sobre as novas proposições para tratar esta modalidade.
The Impact of Hanja-Based Syllables on Korean Vocabulary Learning
Authors: Muscanto Isaac 
Published: April 2019

ABSTRACT
Sino-Korean words represent over half of Korean vocabulary, but since most modern Korean is written phonetically in hangul, the semantic connections between related words are not readily transparent to most learners without hanja instruction. This pilot study investigates the benefits of a hanja education that focuses exclusively on the sound-to-meaning relationship of individual hanja-based syllables, for example, teaching students that the syllable 수/swu is the phonetic pronunciation of the hanja for water. It provides evidence that teaching the meaning of hanja morphemes can help students retain new vocabulary over a short period of time and raises the possibility that hanja syllable education could act as a substitute for more comprehensive forms of hanja education.
Into the Dragons' Den: Practicing KFL Business Communication Skills Through Project-Based Learning
Authors: Choi Yujeong 
Published: April 2019

ABSTRACT
Project-based learning (PBL), despite its potential for creating links between knowledge and action and enabling students to apply their knowledge to solving an authentic problem (Markham, 2011), has been underutilized in language courses. This article describes a project-based activity designed and implemented in a Korean for occupational purposes course at a university in Canada. Modeled after the structure of the television program Dragons' Den, the project provides students with a realistic simulation to practice and develop presentation skills. Working in teams, students choose a product or service item and develop a range of promotion plans culminating in a sales pitch to “investors.”

Sociale zekerheid en controle op detacheringen binnen de EU. Nieuwe wending in de rol van de detacheringsverklaringen bij fraude
Deze bijdrage annoteert het arrest Altun (C-359/16) van het Hof van Justitie van de Europese Unie over de betekenis van de A1-verklaringen bij de toepassing van de Europese socialezekerheidscoördinatie (Verordening 883/2004). Deze zaak ging over de controle die de ontvangstlidstaten kunnen uitoefenen op de correcte toepassing van de regels met betrekking tot de vaststelling van de toepasselijke socialezekerheidswetgeving bij detachering binnen de EU. Dit artikel gaat op de eerste plaats dieper in op de voorwaarden met betrekking tot de toepassing van deze detacheringsregels en op de tot nog toe bestaande rechtspraak van het Hof van Justitie over de betekenis van de detacheringsverklaringen. Het licht dan verder toe hoe het Hof aan deze rechtspraak een nieuwe wending heeft gegeven door de rechter van de ontvangstlidstaat de mogelijkheid te geven om, indien fraude kan worden aangetoond, deze verklaringen naast zich neer te leggen en zijn eigen socialezekerheidswetgeving toe te passen. Het concludeert dat deze rechtspraak de mogelijkheden om fraude en sociale dumping tegen te gaan slechts in beperkte mate heeft uitgebreid.
Arbeidstijdregulering en oproeparbeid

Arbeidstijdregulering en oproeparbeid
In het Matzak-arrest breidt het Hof van Justitie EU het begrip arbeidstijd - onder voorwaarden - uit tot thuis doorgebrachte wachttijd. Het arbeidstijdenrecht biedt tot dusver slechts beperkte bescherming tegen oproeparbeid, terwijl de daaraan verbonden onzekerheid de gezondheid en het welzijn van steeds grotere groepen werknemers bedreigt. In deze bijdrage wordt onderzocht voor welke oproepcontracten het aanmerken van wachttijd als arbeidstijd soelaas biedt, waarbij tevens wordt ingegaan op het verband met de WML en de oproeptermijn in de Wet Arbeidsmarkt in Balans.
