Pollination Ecology of Rhynchosia Heynei Wight and Arn. (Leguminosae), An Endemic Medicinal Herbaceous Shrub Species of Peninsular India
Authors: Raju A. J. Solomon , Ramana K. Venkata 
Published: April 2018

Rhynchosia heynei is an endemic shrub in dry deciduous forests of peninsular India. It is medicinally important and used locally for the treatment of different diseases. Despite its medicinal value and endemic status, no studies were made on the pollination ecology of this shrub to understand the factors leading to its endemic status. In this connection, the standard protocols were followed for the systematic study of the pollination in the Nallamalai forest of Eastern Ghats of Andhra Pradesh. The study indicated that the plant produces nectariferous bisexual flowers. The flowers were self-compatible and equipped with explosive pollination mechanism adapted for melittophily. The fruit set occurred through self and cross-pollination. Mature and dry pods dehisce explosively to disperse seeds. Regeneration occurred through perennial root stock and seeds during rainy season but the regeneration rate is poor due to rocky and dry habitat with little moisture and nutrient content.

Effects of Alternative Fish Species Amblypharyngodon Mola for Traditional Carp Polyculture in Nepal
Authors: Karn Basant Kumar , Gupta Ranjana , Rai Sunila 
Published: April 2018

To increase the maximum productivity is prime aim in fish aquaculture from past few years. The increase in maximum standing crop of a pond depends upon the wider range of available foods in ecological niches from the selection of complementary species growing together. The present work was conducted in an attempt to identify the suitable fish species combinations among Hypophthalmichthys molitrix, Aristichthys nobilis, Ctenopharyngodon idella, Cyprinus carpio with the introduction of Amblypharyngodon mola in the prevalent method of fish polyculture system practiced in Nepal. The experiment was conducted for 120 days, in twelve 100 m2 earthen ponds which comprised the initial growing period of fish. As control, one pond was stocked with a species ratio usually employed in the country; H. molitrix (35 %), A. nobilis (10 %), L. rohita (15 %), C. mrigala (10 %), C. idella, (5 %) and C. carpio (25 %). Treatment 2 was stocked with the H. molitrix, A. nobilis, L. rohita and C. mrigala. Treatment 3 was stocked with the H. molitrix, A. nobilis, L. rohita, C. mrigala and C. idella and Treatment 4 was stocked with the H. molitrix, A. nobilis, L. rohita, C. mrigala and C. idella and C. carpio. Each treatment had three replicates. Carp fishes were stocked with stocking density 15000 ha -1 in all treatments. A. mola was stocked @ 50000 ha-1 in treatments, 2, 3 and 4. No significant correlation was found between the growth rate of fish species and the water quality parameters. The final weight of different species, in different treatments, showed statistical differences. Considering growth parameters, the best result was obtained in treatment 2. A complete exclusion of the A. mola in treatment 1 had no advantage over the other treatments; however, the combination of Hypophthalmichthys molitrix, Aristichthys nobilis, Labeo rohita and Cirrhinus mrigala allowed the introduction of A. mola, with positive effects. In addition, the introduction of A. mola in the polycultures tested had no effect over the other carp species.

Multiculturalism, Racism and Infectious Disease in the Global City: The Experience of the 2003 SARS Outbreak in Toronto
Authors: Keil Roger , Ali Harris 
Published: April 2018

The 2003 SARS outbreak in Toronto, which killed forty-four and made hundreds sick, tested the multicultural model often presented as the reason for making that city a livable global metropolis. Billed as the “Chinese disease,” SARS connected seamlessly with previous periods of racializing disease assumed to originate from migrants and foreigners in North America. Yet when restaurants in the city’s three Chinatowns remained empty for weeks and close contact with Chinese citizens was avoided by others in public, the dynamics that unfolded also tied in with a new development in Toronto: the formation of the global city. As news on the SARS outbreak spread and the intricate details of travel patterns and infection-pathways became clearer, the relationships of Toronto diasporic communities and business ties with other globalizing cities like Hong Kong, Guangzhou and Singapore became obvious, and Toronto’s vulnerability in the network of global flows of finance, culture, commodities and people was exposed. Our paper provides a narrative of the racialization of infectious disease in the context of Toronto’s multiculturalism and the region’s formation as a major global city. Providing evidence of racialization in public discourse, everyday practices and institutional policies, we advance the hypothesis that the SARS outbreak strained the usually happy appearance of this particular multicultural urban fabric of diversity. This analysis is part of a long-term research project at York University on SARS and the Global City, which addresses the network connectivity of Toronto in the global city hierarchy; the influence of infectious disease; and the re-scaling of the health governance system in Toronto in the wake of the SARS outbreak.
At the Site of Wilderness: Meredith Monk’s Facing North (1990)
Authors: Cauthery Bridget 
Published: April 2018

In 1990, American composer, vocalist, filmmaker and choreographer Meredith Monk became witness to the condition of wilderness while in residency at the Banff Centre in northern Alberta, Canada. The resulting work, Facing North, a collaboration with long-time associate composer Robert Een, grew out of the combined senses of physical and metaphysical isolation engendered by the remote mid-winter setting and Monk’s detachment from her normal, urban life. The piece (and accompanying tone poem later recorded and released in album form in 1992) portrays the interdependence of two people trying to come to terms with their simultaneous being and nonbeing, connection and disconnection, in what Monk perceived as an inimical northern landscape. In “Picture and Witness at the Site of the Wilderness” (2000) Canadian cultural theorist Jonathan Bordo argues that artists and their paintings of wilderness arise “from the very idea of wilderness as positing and effacing a witness to an unwitnessible condition” (Bordo 2000: 228). Such depictions of wilderness, while representing a perceived denial or erasure of human presence, in fact require a witness to affirm the very condition of wilderness. In this paper I argue that in performing wilderness Monk engages in a similar process to the visual artists painting wilderness that Bordo examines. As part of an on-going research project entitled “Choreographing the North” this paper focuses on the rupture that is enacted when trying to represent absence through presence and how this relates to ideas of collecting and colonizing the North. In Facing North Monk performs the mythopoetic divide between cultured Self and untamed Other, realizing in the process that her presence in the wilderness, while resonant, is ultimately self-referential.

Published: April 2018

Kurzfassung
Der digitale Wandel ermöglicht beachtliche Entwicklungsschritte im Bereich des Internets der Dinge und der Prozessautomatisierung. Vorteile, die sich aus dem Einsatz von Technologien des Internets der Dinge ergeben, sind in der Produktionslogistik mittelständischer Unternehmen noch größtenteils ungenutzt. Auf intelligenten Materialbereitstellungshilfsmitteln basierende selbstkonfigurierende Logistiksysteme können die operativen Produktionsplanungs- und Steuerungsprozesse in mittelständischen Unternehmen deutlich verbessern. Die resultierende Erhöhung von Transparenz sowie die Verringerung von Verschwendung in den operativen Prozessen können signifikante Wettbewerbsvorteile für mittelständische Unternehmen schaffen.
Microstructural Characterization of Ultra-High Strength Martensitic Steels

Published: April 2018

Abstract
In the development of steels with increasing strength and toughness, ultra-high strength steel grades with a martensitic microstructure are gaining more importance. From the martensitic transformation product, however, strength-specific quantities derived from the former austenite grain cannot be accessed conveniently. A profound analysis of the prior austenite microstructure, its size distribution and aspect ratio is essential in order to allow conclusions on the mechanical properties. This paper presents an etchant to reveal the prior austenite grains of thermomechanical processed and press hardened martensitic steels. Furthermore, alternative detecting methods such as electron backscatter diffraction (EBSD) and high-temperature laser scanning confocal microscopy were evaluated. It was found that a picric-acid etchant in combination with a prior tempering treatment of the steel enables the visualization of prior austenite grains and their elongation in a micrometer-scale.
Weight loss as a predictor of cancer in primary care: a systematic review and meta-analysis
Authors: Nicholson Brian D , Hamilton William , O’Sullivan Jack , Aveyard Paul , Hobbs FD Richard 
Published: April 2018

BackgroundWeight loss is a non-specific cancer symptom for which there are no clinical guidelines about investigation in primary care.AimTo summarise the available evidence on weight loss as a clinical feature of cancer in patients presenting to primary care.Design and settingA diagnostic test accuracy review and meta-analysis.MethodStudies reporting 2 × 2 diagnostic accuracy data for weight loss (index test) in adults presenting to primary care and a subsequent diagnosis of cancer (reference standard) were included. QUADAS-2 was used to assess study quality. Sensitivity, specificity, positive likelihood ratios, and positive predictive values were calculated, and a bivariate meta-analysis performed.ResultsA total of 25 studies were included, with 23 (92%) using primary care records. Of these, 20 (80%) defined weight loss as a physician’s coding of the symptom; the remainder collected data directly. One defined unexplained weight loss using objective measurements. Positive associations between weight loss and cancer were found for 10 cancer sites: prostate, colorectal, lung, gastro-oesophageal, pancreatic, non-Hodgkin’s lymphoma, ovarian, myeloma, renal tract, and biliary tree. Sensitivity ranged from 2% to 47%, and specificity from 92% to 99%, across cancer sites. The positive predictive value for cancer in male and female patients with weight loss for all age groups ≥60 years exceeded the 3% risk threshold that current UK guidance proposes for further investigation.ConclusionA primary care clinician’s decision to code for weight loss is highly predictive of cancer. For such patients, urgent referral pathways are justified to investigate for cancer across multiple sites.
Inside-out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales

Published: April 2018

Abstract
Systems with tightly packed inner planets (STIPs) are very common. Chatterjee & Tan proposed Inside-out Planet Formation (IOPF), an in situ formation theory, to explain these planets. IOPF involves sequential planet formation from pebble-rich rings that are fed from the outer disk and trapped at the pressure maximum associated with the dead zone inner boundary (DZIB). Planet masses are set by their ability to open a gap and cause the DZIB to retreat outwards. We present models for the disk density and temperature structures that are relevant to the conditions of IOPF. For a wide range of DZIB conditions, we evaluate the gap-opening masses of planets in these disks that are expected to lead to the truncation of pebble accretion onto the forming planet. We then consider the evolution of dust and pebbles in the disk, estimating that pebbles typically grow to sizes of a few centimeters during their radial drift from several tens of astronomical units to the inner, ≲1 au scale disk. A large fraction of the accretion flux of solids is expected to be in such pebbles. This allows us to estimate the timescales for individual planet formation and the entire planetary system formation in the IOPF scenario. We find that to produce realistic STIPs within reasonable timescales similar to disk lifetimes requires disk accretion rates of ∼10−9
M
⊙ yr−1 and relatively low viscosity conditions in the DZIB region, i.e., a Shakura–Sunyaev parameter of α ∼ 10−4.
The ALMA View of GMCs in NGC 300: Physical Properties and Scaling Relations at 10 pc Resolution
Authors: Faesi Christopher M. , Lada Charles J. , Forbrich Jan 
Published: April 2018

Abstract
We have conducted a 12CO(2–1) survey of several molecular gas complexes in the vicinity of H ii regions within the spiral galaxy NGC 300 using the Atacama Large Millimeter Array (ALMA). Our observations attain a resolution of 10 pc and 1

, sufficient to fully resolve giant molecular clouds (GMCs) and the highest obtained to date beyond the Local Group. We use the CPROPS algorithm to identify and characterize 250 GMCs across the observed regions. GMCs in NGC 300 appear qualitatively and quantitatively similar to those in the Milky Way disk: they show an identical scaling relationship between size R and linewidth ΔV (ΔV ∝ R
0.48±0.05), appear to be mostly in virial equilibrium, and are consistent with having a constant surface density of about 60

pc−2. The GMC mass spectrum is similar to those in the inner disks of spiral galaxies (including the Milky Way). Our results suggest that global galactic properties such as total stellar mass, morphology, and average metallicity may not play a major role in setting GMC properties, at least within the disks of galaxies on the star-forming main sequence. Instead, GMC properties may be more strongly influenced by local environmental factors such as the midplane disk pressure. In particular, in the inner disk of NGC 300, we find this pressure to be similar to that in the local Milky Way but markedly lower than that in the disk of M51, where GMCs are characterized by systematically higher surface densities and a higher coefficient for the size–linewidth relation.
Equation of State Dependent Dynamics and Multi-messenger Signals from Stellar-mass Black Hole Formation
Authors: Pan 潘國 Kuo-Chuan 全 , Liebendörfer Matthias , Couch Sean M. , Thielemann Friedrich-Karl 
Published: April 2018

Abstract
We investigate axisymmetric black hole (BH) formation and its gravitational wave (GW) and neutrino signals with self-consistent core-collapse supernova simulations of a non-rotating 40 M
⊙ progenitor star using the isotropic diffusion source approximation for the neutrino transport and a modified gravitational potential for general relativistic effects. We consider four different neutron star (NS) equations of state (EoS): LS220, SFHo, BHBΛϕ, and DD2, and study the impact of the EoS on BH formation dynamics and GW emission. We find that the BH formation time is sensitive to the EoS from 460 to >1300 ms and is delayed in multiple dimensions for ∼100–250 ms due to the finite entropy effects. Depending on the EoS, our simulations show the possibility that shock revival can occur along with the collapse of the proto-neutron star (PNS) to a BH. The gravitational waveforms contain four major features that are similar to previous studies but show extreme values: (1) a low-frequency signal (∼300–500 Hz) from core-bounce and prompt convection, (2) a strong signal from the PNS g-mode oscillation among other features, (3) a high-frequency signal from the PNS inner-core convection, and (4) signals from the standing accretion shock instability and convection. The peak frequency at the onset of BH formation reaches to ∼2.3 kHz. The characteristic amplitude of a 10 kpc object at peak frequency is detectable but close to the noise threshold of the Advanced LIGO and KAGRA, suggesting that the next-generation GW detector will need to improve the sensitivity at the kHz domain to better observe stellar-mass BH formation from core-collapse supernovae or failed supernovae.
A Recollimation Shock in a Stationary Jet Feature with Limb-brightening in the Gamma-Ray-emitting Narrow-line Seyfert 1 Galaxy 1H 0323+342

Published: April 2018

Abstract
We report the discovery of a local convergence of a jet cross section in the quasi-stationary jet feature in the γ-ray-emitting narrow-line Seyfert 1 galaxy (NLS1) 1H 0323+342. The convergence site is located at ∼7 mas (corresponding to the order of 100 pc in deprojection) from the central engine. We also found limb-brightened jet structures at both the upstream and downstream of the convergence site. We propose that the quasi-stationary feature showing the jet convergence and limb-brightening occurs as a consequence of recollimation shock in the relativistic jets. The quasi-stationary feature is one of the possible γ-ray-emitting sites in this NLS1, in analogy with the HST-1 complex in the M87 jet. Monitoring observations have revealed that superluminal components passed through the convergence site and the peak intensity of the quasi-stationary feature, which showed apparent coincidences with the timing of observed γ-ray activities.
Passer de pratiques d’Activité Physique Sportive et Artistique à leur enseignement : quels jeux de langage dans le cadre d’une alternance intégrative ?
Authors: Dastugue Laurent , Escalié Guillaume , Ducès Caroline , Chaliès Sébastien 
Published: April 2018

Cet article propose à partir d’un programme de recherche en anthropologie culturaliste un dispositif de formation permettant de faire vivre une alternance intégrative dans la formation des étudiants se destinant au métier d’enseignant d’EPS (Éducation Physique et Sportive). Précisément, ce dispositif tente de donner la possibilité aux étudiants de prendre appui sur leurs expériences de pratique d’APSA (Activité Physique Sportive et Artistique) pour enseigner. Pour ce faire, il présente trois aménagements du contenu de modules de formation du master MEEF (Métier de l’Éducation, de l’Enseignement et de la Formation) parcours EPS. Ces aménagements technologiques, pensés à partir de postulats empruntés au programme de recherche en anthropologie culturaliste ainsi que leurs retombées en matière de préprofessionnalisation sont ainsi détaillés : (i) apprendre des règles en tant que pratiquant, (ii) s’essayer à l’enseignement des règles dans une situation de simulation, (iii) enseigner des règles à des élèves. Les résultats obtenus montrent que le dispositif mis en place a permis aux étudiants de se mettre en activité en tant qu’enseignant en faisant jouer partiellement les règles apprises en tant que pratiquant. Les étudiants ont été confrontés à des difficultés pour s’appuyer sur l’ensemble des aspects constitutifs de ces règles pour enseigner. À partir de ce constat, des pistes d’aménagement de la formation sont envisagées.
La Banque centrale européenne et la crise des dettes souveraines : politique monétaire, politique économique ou état d’exception ?
Authors: Grégoire Guillaume 
Published: April 2018

L’affaire Outright Monetary Transactions (OMT), qui a vu s’opposer le Tribunal constitutionnel fédéral allemand et la Cour de justice de l’Union européenne (CJUE) sur la question de la conformité au droit de l’Union européenne de l’action de la Banque centrale européenne (BCE) lors de la crise des dettes souveraines de 2010-2012, constitue sans aucun doute, à ce jour, l’illustration la plus éclatante de la controverse relative à l’existence (ou non) d’une mutation constitutionnelle tacite du mandat de la BCE. Dans son arrêt du 21 juin 2016, le Tribunal constitutionnel fédéral confirme la conformité du programme monétaire OMT au droit de l’Union et à la Loi fondamentale allemande, mais n’en maintient pas moins de « sérieuses objections » à l’encontre du raisonnement de la CJUE, témoignant ainsi de la persistance de certaines tensions entre, d’une part, les interventions de la BCE et, d’autre part, les dispositions du Traité sur le fonctionnement de l’Union européenne (TFUE) relatives à ses compétences.
Est-il pertinent de durcir le droit européen de l’environnement ?
Authors: Boyer-Allirol Béatrice , Barbu Elena 
Published: April 2018

Depuis le 1 er janvier 2017, la Directive 2014/95/UE oblige les entreprises cotées, les banques et les compagnies d’assurance européennes de plus de 500 salariés à publier les informations relatives à leurs impacts environnementaux. Dans ce contexte, nous nous interrogeons sur la pertinence de durcir le droit européen de l’environnement. Pour cela, nous analysons les cadres réglementaires des pays européens avant la Directive 2014/95/UE, afin de regrouper les pays dans trois catégories : (1) les pays de droit dur, qui ont réglementé ou légiféré le reporting environnemental, (2) les pays de droit souple, qui proposent des lignes directrices ou des codes de bonne conduite émanant de l’État ; et (3) les pays de droit flou n’ayant ni législation ni recommandation de la part de l’État, mais ayant des initiatives professionnelles sporadiques. Ensuite, nous choisissons trois pays correspondant à chaque catégorie réglementaire (respectivement la France, l’Allemagne et l’Italie) et nous comparons l’impact du cadre réglementaire sur le niveau de divulgation environnementale des entreprises par des analyses statistiques. Les résultats montrent les effets bénéfiques d’une réglementation obligatoire. En effet, les divulgations environnementales des entreprises françaises réglementées par un droit dur sont supérieures à celles des entreprises allemandes soumises à un droit souple ou à celles des entreprises italiennes assujetties à un droit flou. Il est donc opportun de durcir le droit de l’environnement en Europe.
