The Extended H i Disk and Star Formation in the Dwarf Spiral Galaxy NGC 4701
Authors: Das Mousumi , Sengupta Chandreyee , Honey M. 
Published: January 2019

Abstract
We present H i, optical, and near-infrared observations of the nearby bulgeless, dwarf spiral galaxy NGC 4701. The galaxy lies on the Virgo filament and is one of the most gas-rich dwarfs in our local environment. Our aim is to understand the gas-disk morphology of the galaxy and see how it relates to the star formation in its disk. Our Hα observations reveal a small star-forming disk associated with the old stellar disk of radius ∼50″. However, the B-band and near-UV GALEX emission extend out to a radius of R

b25 = 108″, revealing an extended star-forming disk lying in the halo-dominated region of the galaxy. The H i disk extends out to a radius of ∼200″, which is close to four times the size of the old stellar disk. The rotation curve has a flat rotation velocity of ∼125 km s−1 and starts falling after a radius of 160″, indicating that the dark matter mass is at least ∼76% of the galaxy mass. The environment and H i rich nature suggest that cold gas accretion could be driving the star formation in the outer blue disk. The disk morphology and star formation in NGC 4701 are very similar to those of late-type spirals that have extended UV disks. Thus, our observations lead us to conclude that NGC 4701 is a classic example of a late-type dwarf spiral galaxy and its nature supports the idea that dwarfs also follow a morphological sequence similar to spirals on the Hubble Sequence.
Constraining Theories of Polarized SiO Maser Transport: Multi-epoch Analysis of a π/2 Electric Vector Rotation Feature
Authors: Tobin T. L. , Kemball A. J. , Gray M. D. 
Published: January 2019

Abstract
The detailed polarization mechanisms of SiO masers originating from the near-circumstellar environment of asymptotic giant branch stars are not yet definitively known. Prevailing theories are broadly classified as either Zeeman or non-Zeeman in origin, the latter including effects such as anisotropic pumping or anisotropic resonant scattering. The predicted behavior of the linear and circular polarization fractions and the electric vector position angle (EVPA) vary by theory. In particular, individual maser features that exhibit a rotation in linear polarization of ∼π/2 as a function of frequency over their extent can be utilized as a test of several maser polarization transport theories. In this paper, we analyze one SiO (ν = 1, J = 1 − 0) maser feature toward the Mira variable, TX Cam, that exhibits this internal polarization rotation and persists across five epochs (spanning ∼3 months). We compare our results to the predictions by several maser polarization theories and find that the linear polarization across the feature is consistent with a geometric effect for a saturated maser originating when the angle between the projected magnetic field and the line of sight (θ) crosses the Van Vleck angle θ

F
∼ 55°. However, the EVPA exhibits a smooth rotation across the spatial extent of the feature rather than the expected abrupt π/2 flip. We discuss possible explanations for this discrepancy and alternative theories. Circular polarization across the feature is also analyzed, and it is most accurately described by Zeeman effects giving rise to a circular polarization fraction of the form

Detection of Rossby Waves in the Sun using Normal-mode Coupling
Authors: Hanasoge Shravan , Mandal Krishnendu 
Published: January 2019

Abstract
Rossby waves play a fundamental role in angular momentum processes in rotating fluids. In addition to the potential to shed light on physical mechanisms operating in the solar convection zone, the recent detection of Rossby waves in the Sun also serves as a means of comparison between different helioseismic methods. Time–distance helioseismology, ring-diagram analysis, and other techniques have all proven successful in recovering the Rossby-wave dispersion relation from analyses of Helioseismic and Magnetic Imager data (HMI). In this article, we demonstrate that analyses of two years of HMI global-mode-oscillation data using the technique of normal-mode coupling also show signatures of Rossby waves. In addition to providing an independent means of inferring Rossby waves, this detection lends credence to the methodology of mode coupling and encourages a more complete exploration of its possibilities.
Whistler Fan Instability Driven by Strahl Electrons in the Solar Wind

Published: January 2019

Abstract
We present a theoretical analysis of electron heat flux inhibition in the solar wind when a significant portion of the heat flux is carried by strahl electrons. We adopt core-strahl velocity distribution functions typical for the solar wind at 0.3–4 au to demonstrate that strahl electrons are capable of generating highly oblique whistler waves at wave numbers kρ

e
∼ 1, where ρ

e
is typical thermal electron gyroradius. The whistler waves are driven by electrons in the anomalous cyclotron resonances (the fan instability) and propagate at typical angles of about 70°–80° to the strahl that is usually anti-sunward. The group velocity of the whistler waves is predominantly parallel to the strahl, thereby facilitating efficient scattering of strahl electrons. We suggest that the highly oblique whistler waves drive pitch-angle scattering of strahl electrons, resulting in halo formation and suppressing the heat flux of strahl electrons below a threshold that is shown to depend on β

e
. The proposed fan instability is fundamentally different from the whistler heat flux instability driven by the normal cyclotron resonance with halo electrons and being ineffective in suppressing the heat flux of the strahl.
A world dataset on the geographic distributions of Solenidae razor clams (Mollusca: Bivalvia)
Authors: Saeedi Hanieh , Costello Mark 
Published: January 2019

Using this dataset, we examined the global geographical distributions of Solenidae species in relation to their endemicity, species richness and latitudinal ranges and then predicted their distributions under future climate change using species distribution modelling techniques (Saeedi et al. 2016a, Saeedi et al. 2016b). We found that the global latitudinal species richness in Solenidae is bi-modal, dipping at the equator most likely derived by high sea surface temperature (Saeedi et al. 2016b). We also found that most of the Solenidae species will shift their distribution ranges polewards due to global warming (Saeedi et al. 2016a). We also provided a comprehensive review of the taxon to test whether the latitudinal gradient in species richness was uni-modal with a peak in the tropics or northern hemisphere or asymmetric and bimodal as proposed previously (Chaudhary et al. 2016).
This paper presents an integrated global geographic distribution dataset for 77 Solenidae taxa, including 3,034 geographic distribution records. This dataset was compiled after a careful data-collection and cleaning procedure over four years. Data were collected using field sampling, literature and from open-access databases. Then all the records went through quality control procedures such as validating the taxonomy of the species by examining and re-identifying the specimens in museum collections and using taxonomic and geographic data quality control tools in the World Register of Marine Species (WoRMS) and the r-OBIS package (Provoost and Bosch 2017). This dataset can thus be further used for taxonomical and biogeographical studies of Solenidae.
The CLUZ plugin for QGIS: designing conservation area systems and other ecological networks
Authors: Smith Robert 
Published: January 2019

Systematic conservation planning is the most widely used approach for designing conservation area systems and other types of ecological network. Thus, user-friendly decision support tools are needed to guide conservation planners when using this approach.
CLUZ is a QGIS plugin that can be used for on-screen conservation planning and also acts as an interface for Marxan, the most widely used spatial conservation prioritisation software package.
Une perspective centrée sur la personne de la « psychopathologie »
Authors: Bohart Art , Berthoud Laurent 
Published: January 2019

Je présente une perspective centrée sur la personne relative à la psychopathologie. Les personnes possèdent une capacité naturelle de guérison de soi et de développement de leur sagesse interne afin de s’auto-organiser. À mes yeux, la psychopathologie survient lorsque divers facteurs empêchent les personnes d’utiliser ces capacités de manière productive. Les conditions de valeur sont un facteur majeur. Elles sont omniprésentes et ne se rencontrent pas seulement durant l’enfance, mais durant le reste de la vie également. Je conclus qu’il est nécessaire que nous changions la société – elle doit devenir plus acceptante et empathique – en vue de se débarrasser de la « psychopathologie ».
Que signifie être humain ?
Authors: McMillan Mhairi , Ducroux-Biass Françoise 
Published: January 2019

Ce texte, fruit d’une réflexion poussée sur ce que signifie « être humain », explore les différents modes d’être en relation, allant de la première relation au monde, celle que nous avons avec nous-même, à la dernière, celle que nous avons avec la mort. Cet article décrit le processus de l’évolution du soi. L’auteure s’appuie sur la théorie de Carl Rogers, notamment de sa vision du soi, et sur diverses philosophies spirituelles pour étayer son propos, décrivant ainsi de multiples considérations sur la définition du « soi » : soi « organismique », soi « ringard », « vrai » soi, « non-soi », soi « illusoire ». Elle nous parle de ses expériences d’écoute et d’empathie, clés de la mise en résonance avec l’autre. Comment cette résonance est-elle possible s’interroge-t-elle. Sans parler de certitudes, elle nous entraîne dans des considérations mystiques qui ouvrent sur des perspectives contrastantes sur la conscience de soi. Un tel cheminement nous invite à la réflexion. Sommes-nous qui nous croyons être ? Comment notre statut d’être humain nous permet-il d’être en relation ? Faisons-nous l’expérience de l’Unité avec l’univers ? Autant de questions qui restent ouvertes.
Factors Associated With Epithelial Defects After Penetrating Keratoplasty
Authors: Chou Lin , Cohen Elisabeth J , Laibson Peter A , Rapuano Christopher J 
Published: January 2019

ABSTRACT
A prospective study of 84 consecutive patients undergoing penetrating keratoplasty over a 6-month interval was performed to identify risk factors for postoperative epithelial defects.
Data collected included donor age, host age, time postmortem until enucleation, general health of donor and host, any history of glaucoma, any surgical procedure, the indication for penetrating keratoplasty, and the presence of any epithelial defect preoperatively in the donor. Patients were evaluated 1 day postoperatively for any epithelial defects greater than 1 mm2 central to the sutures. Single-variable associations and multiple stepwise logistic regression using standard biostatistical techniques were performed.
Thirty-one percent (26 of 84) of the patients had epithelial defects on the first postoperative day. Only diabetes in the donor (P = .03) and longer death-toenucleation times (P = .03) were associated with an increased risk of epithelial defects. We conclude that diabetes in the donor and longer death-to-enucleation times predispose to epithelial defects after penetrating keratoplasty.
Imaginaires de l'espace fluvial : aspects d'une géocritique de l'Orénoque
Authors: Katsika Karolina 
Published: January 2019

Au XIXe siècle, le fleuve Orénoque apparaît dans la littérature comme un espace « sauvage » et inquiétant, dépaysant, un espace de danger mortel mais aussi de l'extraordinaire. Une large part est faite à la description de la faune et de la flore. En revanche, aux XXe-XXIe siècles, des mutations s'opèrent concernant la perception de l'espace fluvial ainsi que son rôle dans la narration. L'espace fluvial semble davantage être un lieu où se joue un enjeu intérieur et le voyage devient quête personnelle. S'il reste un espace de souffrance, celle-ci peut aboutir – ou pas – à une transformation et une renaissance. Le récit enardien, offre l'image contemporaine d'un espace de circulation marchande.
A preliminary survey of dementia amongst geriatric patients admitted to a single medical unit at the Teaching Hospital Jaffna (THJ), Sri Lanka using a locally validated scale - the concise cognitive assessment scale (CONCOG)
Authors: Arasalingam A. , Suganthan N. 
Published: January 2019

Testing cognition is the background to dementia assessment. Most available assessment batteries are not developed or validated in developing countries. The Concise Cognitive test (CONCOG) validated in an elderly urban Sri Lankan population tested orientation to time, naming, registering 4 words, copying, verbal fluency and recall of the 4 words using native vernacular, creating a culturally acceptable and contextualized assessment tool. Patients above the age of 60 years admitted to the professorial medical unit of THJ were screened after excluding confounding factors (delirium, sepsis, chronic illness, degenerative neurological diseases) which would have affected the test results. Patients who consented voluntarily were screened using the CONCOG test. A convenient sampling method was used. The severity was decided based on the score (20 - 23 mild dementia, 13 – 19 moderate dementia and 12 or less severe dementia) Of 1001 patients screened (mean age 73.29±5.8 years; 522 or 52.1% males; 479 or 47.9% females) 675 (67.43%) had cognitive impairment. Of those with cognitive impairment mean age was 75.41±5.69, 329(48.7%) males and 346(51.3%) females. 293/675(43.41%) had mild dementia (mean age 71.8±3.66; 47.1% males). 325/675 (48.15%) had moderate dementia (mean age 77.46±4.93; 49.5% males). 57/675 (8.44%) had severe dementia (mean age 82.3±6.23; 52.6% males). Of the 1001 screened only 326(32.57%) had no evidence of dementia. In Conclusion 91.7% of subjects with cognitive impairment had mild and moderate dementia which responds to cognitive rehabilitation and medication. Early detection should be encouraged. A larger population based screening should be carried out to conform the above findings.

6. junija 2018 je na Inštitutu Jožef Stefan potekal dogodek, na katerem so bili javnosti predstavljeni cilji in prvi rezultati projekta Nova slovnica sodobne standardne slovenščine: viri in metode (ARRS J6-8256). Namen projekta je razviti jezikoslovno metodologijo za računalniško podprto analizo sodobne slovenščine, kakršna je zajeta v referenčnih besedilnih korpusih slovenskega jezika. Z novo metodologijo bodo pripravljene baze jezikovnih podatkov, ki bodo po koncu projekta skupnosti odprto na voljo za raziskave, gradnjo jezikovnih priročnikov ter učnih gradiv, razvoj jezikovnotehnoloških orodij ipd.
Omenjeno projektno financiranje izdelave nove slovnice sicer ne pokriva, vendar že priprava podatkovnih baz zahteva premisleke o trenutnih prioritetah slovenskega prostora. Sodobni slovnični opis je brez dvoma med cilji za prihodnost, ni pa še v konsenza, kako naj bo oblikovan, da bo odgovoril na (različne) potrebe sodobne družbe. Da odpremo razpravo, smo na projektnem dogodku organizirali strokovni posvet, opredeljen z naslednjimi vprašanji: kdo so deležniki, ki bi lahko projektne rezultate uporabljali; na kaj moramo pri pripravi paziti, da bodo podatki optimalno uporabni; kakšno oz. katero slovnico potrebujemo najprej; katere so metodološke in logistične premise njene priprave; kje je trenutno slovensko slovničarstvo in kakšen razvoj si lahko obetamo; kakšne so potrebe po slovničnih podatkih pri različnih uporabniških skupinah ter kaj bi trenutne vrzeli najbolje naslovilo.
Extending injury prevention methodology to chemical terrorism preparedness: The Haddon Matrix and sarin

Published: January 2019

The Haddon Matrix offers a classic epidemiologi¬cal model for studying injury prevention. This method-ology places the pudlic health concepts of agent, host, and environment within the three sequential phases of an injury-producing incident—pre-event, event, and postevent. This study uses this methodology to illus-trate how it could de applied in systematically prepar-ing for a mass casualty disaster such as an unconven-tional sarin attack in a major urdan setting. Nineteen city, state, federal, and military agencies responded to the Haddon Matrix chemical terrorism preparedness exercise and offered feeddack in the data review ses-sion. Four injury prevention strategies (education, engineering, enforcement, and economics) were applied to the individual factors and event phases of the Haddon Matrix. The majority of factors identified in all phases were modifiadle, primarily through edu-cational interventions focused on individual health-care providers and first responders. The Haddon Matrix provides a viadle means of studying an unconventional prodlem, allowing for the identification of modifiadle factors to decrease the type and severity of injuries following a mass casualty dis-aster such as a sarin release. This strategy could de successfully incorporated into disaster planning for other weapons attacks that could potentially cause mass casualties.

Published: January 2019

IntroductionFamilial Mediterranean fever (FMF) is an autosomal recessive disease. It is characterized by recurrent crises of fever and serosal inflammation. Although FMF patients are symptom free in between attacks, subclinical inflammation continues during the attack-free period. Such patients with inflammatory status have an increased risk of atherosclerotic cardiovascular complications. We attempted to elucidate the role of arterial wall thickening as a predictor of early atherosclerosis in children affected by FMF and to clarify the links between carotid intima media thickness and the markers of subclinical inflammation serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), neutrophil-to-lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR).Material and methodsIt is a case control study. The study comprised 45 Egyptian children diagnosed with FMF and 45 healthy children of matched age and sex who served as controls, without family history or clinical manifestations suggestive of FMF. Laboratory investigations included complete blood count, NLR, PLR, ESR, C-reactive protein and lipid profile. Serum amyloid A levels were determined in both groups using enzyme linked immunosorbent assay. Assessment of the common carotid artery intima media thickness (CIMT) in the FMF patients was carried out.ResultsThe level of SAA was significantly higher in patients than the control subjects with a mean value of 38.30 ng/ml and 23.43 ng/ml respectively (p < 0.001). Our patients showed significantly higher PLR when compared to controls (p < 0.001). The mean right and left carotid intima media thickness in patient and control groups showed a highly significant difference (p = 0.005 and 0.036 respectively).ConclusionsThe mean carotid intima media thickness is higher in cases than the control group. Hence carotid intima media thickness may be used as a tool in the prediction of any atherosclerotic burden in those children.
Kernpunten van de controle en de transparantie erover in bestuursverslag, verslag van de raad van commissarissen en de jaarrekening
Authors: De Bos Auke , De Jong Martijn , Strating Henk 
Published: January 2019

De uitgebreide controleverklaring geeft meer informatie over de controle. Omdat het bestuur en de commissarissen verantwoordelijk zijn voor de verslaggeving van de onderneming mag verwacht worden dat zij in de jaarrekening en in hun verslagen ook ingaan op de onderwerpen die de accountant bespreekt als kernpunten van de controle. In de praktijk blijkt dit in Nederland voor verbetering vatbaar, waarbij geleerd kan worden van de ervaringen in het Verenigd Koninkrijk.
De Corporate Governance Code van het Verenigd Koninkrijk geeft uitvoerige voorschriften voor de rapportage door auditcommissies, welke in de Nederlandse code ontbreken. Hierdoor is de kwaliteit van de audit committee reports in het Verenigd Koninkrijk aanzienlijk hoger dan de kwaliteit van de Nederlandse verslagen van de raad van commissarissen. Daarom pleiten we ervoor in de Nederlandse code soortgelijke bepalingen op te nemen voor raden van commissarissen/auditcommissies als in het Verenigd Koninkrijk, zodat transparantie en daarmee de rollen en verantwoordelijkheden van bestuur, commissarissen en de accountant duidelijk en consistent zijn. Echter ook zonder meer gedetailleerde regelgeving zouden we meer verwachten van de kwaliteit van de verslaggeving door ondernemingen. De controleverklaring bevat in Nederland in een aantal gevallen meer informatie dan de onderneming zelf communiceert.
Om de transparantie van verslaggeving te verbeteren is het nodig dat het bestuur rapporteert over de belangrijkste risico’s met een financiële impact op de jaarrekening. De raad van commissarissen brengt als intern toezichthouder verslag uit over de wijze van toezicht en hoe is omgegaan met en transparantie wordt gegeven over de materiële risico’s en onzekerheden. Vervolgens beschrijft de accountant hoe hij deze risico’s heeft geadresseerd in de controle.
Quantifying the light absorption and source attribution of insoluble light-absorbing particles on Tibetan Plateau glaciers between 2013 and 2015

Published: January 2019

Abstract. The deposition of
insoluble light-absorbing particles (ILAPs) on snow and ice surfaces can
significantly reduce albedo, thereby accelerating the melting process. In
this study, 67 ice samples were collected from seven glaciers located on the
Tibetan Plateau (TP) between May 2013 and October 2015. The mixing ratios of
black carbon (BC), organic carbon (OC), and mineral dust (MD) were measured
with an integrating sphere/integrating sandwich spectrophotometer (ISSW) system,
which assumes that the light absorption of MD is due to iron oxide (Fe). Our
results indicate that the mass-mixing ratios of BC, OC, and Fe exhibit
considerable variability (BC: 10–3100 ng g−1; OC:
10–17 000 ng g−1; Fe: 10–3500 ng g−1) with respective mean
values of 220±400 ng g−1, 1360±2420 ng g−1, and
240±450 ng g−1 over the course of the field campaign. We
observed that for wavelengths of 450–600 nm, the measured light absorption
can be largely attributed to the average light absorption of BC (50.7 %)
and OC (33.2 %). Chemical elements and selected carbonaceous particles
were also analyzed for source attributions of particulate light absorption
based on a positive matrix factorization (PMF) receptor model. Our findings
indicate that on average, industrial pollution (33.1 %), biomass or
biofuel burning (29.4 %), and MD (37.5 %) constitute the principal
sources of ILAPs deposited on TP glaciers.
