Comparison of corrected serum calcium changes following thyroid and non thyroid neck surgeries
Authors: Sinha Saloni , Baskota Dharma Kanta 
Published: March 2018

Objective: To compare the corrected serum calcium changes following thyroid and non thyroid neck surgeries.Material and Methods: It was a prospective, longitudinal and comparative study, done in Ganesh Man Singh Memorial Academy of ENT and Head and Neck Studies, Tribhuvan University, Teaching hospital, Kathmandu, Nepal. Convenient sample size was taken of patients undergoing thyroid and non thyroid neck surgeries under general anaesthesia, between 1st November 2009 to 30th April 2011.Result: Total 87 cases were included which comprises 41 cases of thyroid and 46 cases of non thyroid neck lesions. Total females in thyroid cases were 39 out of 41 and in non thyroid cases 25 out of 46. The mean corrected calcium in thyroid cases were 2.04 ± 0.07, 1.75 ± 0.26, 1.92 ± 0.16 and 2.00 ± 0.07 in pre-operative, recovery room (immediate post-operative), post-operative day-1(POD 1) and post-operative day-4(POD- 4) respectively. The mean calcium changes in non thyroid cases were 2.04 ± 0.09, 1.89 ± 0.19, 1.94 ± 0.13 and 1.99 ± 0.04 in pre-operative period, recovery room (immediate post-operative), post-operative day-1(POD-1) and post-operative day-4 (POD- 4) respectively. In both thyroid and non thyroid group, the calcium drop was statistically significant (< 0.05) in recovery. Rest were not significant statistically. The mean differences from pre-operative to recovery and preoperative to POD-1 corrected calcium changes were also significant in both thyroid and non thyroid groups. The mean difference between preoperative to POD-4 was not significant in both groups.Conclusion: After comparing the corrected serum calcium changes following thyroid and non thyroid neck surgeries, the transient post-operative hypocalcaemia is not a thyroid surgery dependent phenomenon. Haemodilution is the main factor for hypocalcaemia in immediate postoperative period in all major neck surgeries.Nepalese Journal of ENT Head and Neck Surgery, Vol. 6, No. 1, 2015
Structural, magnetic and optical properties of Al-substituted nickel ferrite nanoparticles
Authors: Vigneswari Thangaraj , Raji Palanimuthu 
Published: March 2018

AbstractAluminium (Al) substituted nickel ferrite (NiAlxFe2-xO4 with x = 0.0, 0.5 and 1.0) nanoparticles were synthesized by the technique of co-precipitation. The microstructural and optical properties of nickel ferrite nanoparticles were meticulously evaluated from X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis and UV–vis spectroscopy. The X-ray diffraction pattern of nanoparticles confirmed the single phase of cubic spinel structure. The particle size of nickel ferrite nanoparticles was in the range of 25–35 nm, while the lattice parameter “a” decreased with respect to Al content. The presence of Ni, Fe, Al, and O elemental peaks in the energy dispersive X-ray spectrum confirmed the formation of nickel ferrite nanoparticles. The functional groups of Al–Ni spinel ferrite phase were further confirmed from Fourier transform infrared spectroscopy. Two major absorption bands in the IR spectrum were observed at 600 cm−1 (the high frequency band, ν1) and 450 cm−1 (the low frequency band, ν2) from tetrahedral (A) and octahedral (B) interstitial sites in the spinel lattice. The magnetic hysteresis curves were recorded with respect to Al concentration at room temperature using vibrating sample magnetometry. The magnetization and coercivity of nickel ferrite were decreased as the Al contents increased.
Testing the Binary Hypothesis: Pulsar Timing Constraints on Supermassive Black Hole Binary Candidates

Published: March 2018

Abstract
The advent of time domain astronomy is revolutionizing our understanding of the universe. Programs such as the Catalina Real-time Transient Survey (CRTS) or the Palomar Transient Factory (PTF) surveyed millions of objects for several years, allowing variability studies on large statistical samples. The inspection of ≈250 k quasars in CRTS resulted in a catalog of 111 potentially periodic sources, put forward as supermassive black hole binary (SMBHB) candidates. A similar investigation on PTF data yielded 33 candidates from a sample of ≈35 k quasars. Working under the SMBHB hypothesis, we compute the implied SMBHB merger rate and we use it to construct the expected gravitational wave background (GWB) at nano-Hz frequencies, probed by pulsar timing arrays (PTAs). After correcting for incompleteness and assuming virial mass estimates, we find that the GWB implied by the CRTS sample exceeds the current most stringent PTA upper limits by almost an order of magnitude. After further correcting for the implicit bias in virial mass measurements, the implied GWB drops significantly but is still in tension with the most stringent PTA upper limits. Similar results hold for the PTF sample. Bayesian model selection shows that the null hypothesis (whereby the candidates are false positives) is preferred over the binary hypothesis at about 2.3σ and 3.6σ for the CRTS and PTF samples respectively. Although not decisive, our analysis highlights the potential of PTAs as astrophysical probes of individual SMBHB candidates and indicates that the CRTS and PTF samples are likely contaminated by several false positives.
Constraining Stellar Coronal Mass Ejections through Multi-wavelength Analysis of the Active M Dwarf EQ Peg
Authors: Crosley M. K. , Osten R. A. 
Published: March 2018

Abstract
Stellar coronal mass ejections remain experimentally unconstrained, unlike their stellar flare counterparts, which are observed ubiquitously across the electromagnetic spectrum. Low-frequency radio bursts in the form of a type II burst offer the best means of identifying and constraining the rate and properties of stellar CMEs. CME properties can be further improved through the use of proposed solar-stellar scaling relations and multi-wavelength observations of CMEs through the use of type II bursts and the associated flares expected to occur alongside them. We report on 20 hr of observation of the nearby, magnetically active, and well-characterized M dwarf star EQ Peg. The observations are simultaneously observed with the Jansky Very Large Array at their P-band (230–470 MHz) and at the Apache Point observatory in the SDSS u′ filter (λ = 3557 Å). Dynamic spectra of the P-band data, constructed to search for signals in the frequency-time domains, did not reveal evidence of drifting radio bursts that could be ascribed to type II bursts. Given the sensitivity of our observations, we are able to place limits on the brightness temperature and source size of any bursts that may have occurred. Using solar scaling rations on four observed stellar flares, we predict CME parameters. Given the constraints on coronal density and photospheric field strength, our models suggest that the observed flares would have been insufficient to produce detectable type II bursts at our observed frequencies. We consider the implications of these results, and other recent findings, on stellar mass loss.
Effects of Alfvénic Drift on Diffusive Shock Acceleration at Weak Cluster Shocks
Authors: Kang Hyesung , Ryu Dongsu 
Published: March 2018

Abstract
Non-detection of γ-ray emission from galaxy clusters has challenged diffusive shock acceleration (DSA) of cosmic-ray (CR) protons at weak collisionless shocks that are expected to form in the intracluster medium. As an effort to address this problem, we here explore possible roles of Alfvén waves self-excited via resonant streaming instability during the CR acceleration at parallel shocks. The mean drift of Alfvén waves may either increase or decrease the scattering center compression ratio, depending on the postshock cross-helicity, leading to either flatter or steeper CR spectra. We first examine such effects at planar shocks, based on the transport of Alfvén waves in the small amplitude limit. For the shock parameters relevant to cluster shocks, Alfvénic drift flattens the CR spectrum slightly, resulting in a small increase of the CR acceleration efficiency, η. We then consider two additional, physically motivated cases: (1) postshock waves are isotropized via MHD and plasma processes across the shock transition, and (2) postshock waves contain only forward waves propagating along with the flow due to a possible gradient of CR pressure behind the shock. In these cases, Alfvénic drift could reduce η by as much as a factor of five for weak cluster shocks. For the canonical parameters adopted here, we suggest η ∼ 10−4–10−2 for shocks with sonic Mach number M
s ≈ 2–3. The possible reduction of η may help ease the tension between non-detection of γ-rays from galaxy clusters and DSA predictions.
A Search for Extraterrestrial Intelligence (SETI) toward the Galactic Anticenter with the Murchison Widefield Array
Authors: Tingay S. J. , Tremblay C. D. , Croft S. 
Published: March 2018

Abstract
Following the results of the first systematic modern low-frequency search for extraterrestrial intelligence using the Murchison Widefield Array (MWA), which was directed toward a Galactic Center field, we report a second survey toward a Galactic Anticenter field. Using the MWA in the frequency range 99–122 MHz over a three-hour period, a 625 deg2 field centered on Orion KL (in the general direction of the Galactic Anticenter) was observed with a frequency resolution of 10 kHz. Within this field, 22 exoplanets are known. At the positions of these exoplanets, we searched for narrowband signals consistent with radio transmissions from intelligent civilizations. No such signals were found with a 5σ detection threshold. Our sample is significantly different to the 45 exoplanets previously studied with the MWA toward the Galactic Center, since the Galactic Center sample is dominated by exoplanets detected using microlensing, and hence at much larger distances than the exoplanets toward the Anticenter, found via radial velocity and transit detection methods. Our average effective sensitivity to extraterrestrial transmitter power is therefore much improved for the Anticenter sample. Added to this, our data processing techniques have improved, reducing our observational errors, leading to our best detection limit being reduced by approximately a factor of four compared to our previously published results.
A Possible Progenitor of the Interstellar Sulfide Bond: Rovibrational Characterization of the Hydrogen Disulfide Cation HSSH+
Authors: Fortenberry Ryan C. , Francisco Joseph S. 
Published: March 2018

Abstract

S2H (HSS) has been observed very recently in the interstellar medium, specifically in the Horsehead nebula. The protonated form, S2H2
+, is believed to be a necessary intermediate in its creation in the gas phase in UV-irradiated regions. However, little is known about this radical cation. This work showcases that the trans-HSSH+ isomer is 0.12 eV lower in energy than the cis with a 1.05 eV upper limit to the torsional rotation barrier. Additionally, the vibrational frequencies and rotational constants for both structures are provided in full here for the first time. The cis isomer is likely the more detectable since it possesses a permanent dipole moment and has a high-intensity vibrational frequency for the antisymmetric H−S−S bend at 926 cm−1 (10.8 μm), in the heart of the mid-IR spectral range. A third isomer, H2S−S+ is also reported herein lying ∼0.9 eV in energy above trans-HSSH+. This isomer could play a role in the formation of S2H since it would be kinetically favored in the reaction of sulfur cations with hydrogen sulfide. Further assessment of this third, higher-energy isomer is left for future work.
An Ultradeep Chandra Catalog of X-Ray Point Sources in the Galactic Center Star Cluster
Authors: Zhu Zhenlin , Li Zhiyuan , Morris Mark R. 
Published: March 2018

Abstract
We present an updated catalog of X-ray point sources in the inner 500″ (∼20 pc) of the Galactic center (GC), where the nuclear star cluster (NSC) stands, based on a total of ∼4.5 Ms of Chandra observations taken from 1999 September to 2013 April. This ultradeep data set offers unprecedented sensitivity for detecting X-ray sources in the GC, down to an intrinsic 2–10 keV luminosity of 1.0 × 1031 erg s−1. A total of 3619 sources are detected in the 2–8 keV band, among which ∼3500 are probable GC sources and ∼1300 are new identifications. The GC sources collectively account for ∼20% of the total 2–8 keV flux from the inner 250″ region where detection sensitivity is the greatest. Taking advantage of this unprecedented sample of faint X-ray sources that primarily traces the old stellar populations in the NSC, we revisit global source properties, including long-term variability, cumulative spectra, luminosity function, and spatial distribution. Based on the equivalent width and relative strength of the iron lines, we suggest that in addition to the arguably predominant population of magnetic cataclysmic variables (CVs), nonmagnetic CVs contribute substantially to the detected sources, especially in the lower-luminosity group. On the other hand, the X-ray sources have a radial distribution closely following the stellar mass distribution in the NSC, but much flatter than that of the known X-ray transients, which are presumably low-mass X-ray binaries (LMXBs) caught in outburst. This, together with the very modest long-term variability of the detected sources, strongly suggests that quiescent LMXBs are a minor (less than a few percent) population.
Représentations et pratiques des loisirs des enfants et adolescents : le paradoxe de la dimension éducative des loisirs
Authors: Constans Stéphanie , Gardair Emmanuèle 
Published: March 2018

Cette étude examine, dans le champ des loisirs, les représentations et les pratiques des enfants et des adolescents, à travers, d’une part, l’examen de la littérature scientifique en psychologie, mais aussi en sciences de l’éducation et en sociologie et, d’autre part, le recueil de la parole d’enfants et d’adolescents, usagers de structures de loisirs. 31 enfants, âgés de 5 à 10 ans, inscrits dans un accueil de loisirs sans hébergement de l’agglomération nantaise, et 19 adolescents, âgés de 11 à 18 ans, fréquentant un espace jeunes de l’agglomération rennaise, ont été interrogés au moyen d’entretiens semi-directifs, articulant trois dimensions : la définition et le rôle des loisirs, la définition et le rôle des animateurs, les pratiques effectives et souhaitées. Les résultats, issus d’une analyse de contenu, réalisée à l’aide du logiciel Alceste, confirment notre hypothèse d’une hétérogénéité des représentations et des pratiques et de leur différenciation selon l’âge et le type de structure de loisirs fréquentée (enfants en accueil de loisirs versus adolescents en espace jeunes). L’analyse dégage cinq profils différenciés d’usagers, deux caractéristiques du discours des enfants en accueil de loisirs, trois du discours des adolescents en espace jeunes. Les loisirs constituent une forme d’expression identitaire et marquent une culture d’âge. Plus largement, ces représentations et ces pratiques posent la question de la dimension éducative informelle des loisirs.
Devenir et être parent en situation de précarité
Authors: Pinel-Jacquemin Stéphanie , Koliouli Flora , Kelly-Irving Michelle 
Published: March 2018

La précarité est une situation qui n’est pas sans effet sur le devenir et l’être parent et, bien souvent, ce sont les conséquences négatives qui sont mises en avant. Cette catégorisation vise moins à comprendre, à expliquer, qu’à juger. C’est pourquoi nous avons réalisé une revue de la littérature. Après avoir défini les notions de précarité et de parentalité, nous proposons une réflexion sur l’identité parentale et sur les conséquences spécifiques, induites par ce contexte, sur le processus de parentalité : la périnatalité comme période sensible, un investissement moindre dans la parentalité, des stéréotypes de genre et des styles éducatifs propres ainsi qu’une précarité symbolique qui vient s’ajouter à la précarité économique. Pour finir, des pistes potentielles d’intervention pour venir en aide à ces parents, mis à mal notamment par le regard porté sur eux par la société, ainsi que de recherches scientifiques à approfondir sont indiquées.
Images d’expression et de contre-expression dans le changement psychique. Intérêt paradigmatique du Rorschach
Authors: Gaudriault Pierre 
Published: March 2018

Des images expressives ont une part active dans le développement psychique ; elles apparaissent, notamment, au cours de la psychothérapie, avec le progrès de la mentalisation. Elles répondent à la triple fonction de représentation, d’enveloppe et de transformation définie par Serge Tisseron, mais il peut y avoir aussi des figurations moins favorables, dites contre-expressives , qui manifestent, au contraire, la perte de sens et la destructivité du sujet. Le Rorschach donne un aperçu de ces images expressives et contre-expressives , qui apparaissent également dans les rêves et les représentations diurnes de sujets en psychothérapie. Des thérapies médiatisées, centrées sur l’utilisation d’images réelles, peuvent permettre de faciliter la relation thérapeutique avec ceux dont le traitement est long et difficile.

Published: March 2018

Édouard Claparède est un des fondateurs de la psychologie scientifique et un pionnier de l’éducation nouvelle. Une partie de son œuvre a été consacrée à l’orientation professionnelle. En 1918 il facilite l’ouverture d’un cabinet d’orientation professionnelle au sein de l’Institut Jean-Jacques Rousseau à Genève. Il est l’organisateur des premiers congrès internationaux de psychologie appliquée où l’on traite alors uniquement d’orientation professionnelle. Enfin, il se livre à une réflexion approfondie de la notion d’aptitude. Comment diagnostiquer les aptitudes ? Sont-elles éducables ?
Le vrai-faux procès du franc CFA
Authors: Jacquemot Pierre 
Published: March 2018

Le franc CFA, système monétaire de 15 pays d’Afrique depuis la fin de la Seconde Guerre mondiale et qui a survécu aux indépendances, se trouve mis en question. Le procès est en partie justifié : le franc CFA profite d’abord aux élites rentières. Sa réforme est donc à l’ordre du jour. Elle doit toucher aux symboles qui cristallisent les critiques, mais surtout aux mécanismes qui doivent permettre de mieux financer les économies et contribuer à réduire les facteurs d’inégalités et de pauvreté.

Published: March 2018

AbstractBetween 2004 and 2008, biologists conducted an inventory of breeding birds during May–June primarily in montane areas (&gt;100 m above sea level) of Aniakchak National Monument and Preserve (Aniakchak NMP), Katmai National Park and Preserve (Katmai NPP), and Lake Clark National Park and Preserve (Lake Clark NPP) in southwestern Alaska. Observers conducted 1,021 point counts along 169 transects within 63 10-km × 10-km plots that were randomly selected and stratified by ecological subsection. We created hierarchical N-mixture models to estimate detection probability and abundance for 15 species, including 12 passerines, 2 galliforms, and 1 shorebird. We first modeled detection probability relative to observer, date within season, and proportion of dense vegetation cover around the point, then modeled abundance as a function of land cover composition (proportion of seven coarse-scale land cover types) within 300 m of the survey point. Land cover relationships varied widely among species but most showed selection for low to tall shrubs (0.2–5 m tall) and an avoidance of alpine and dwarf shrub–herbaceous cover types. After adjusting for species not observed, we estimated a minimum of 107 ± 9 species bred in the areas surveyed within the three parks combined. Species richness was negatively associated with elevation and associated land cover types. At comparable levels of survey effort (n = 721 birds detected), species richness was greatest in Lake Clark NPP (75 ± 12 species), lowest in Aniakchak NMP (45 ± 6 species), and intermediate at Katmai NPP (59 ± 10 species). Species richness was similar at equivalent survey effort (n = 973 birds detected) within the Lime Hills, Alaska Range, and Alaska Peninsula ecoregions (68 ± 8; 79 ± 11; 67 ± 11, respectively). Species composition was similar across all three parks and across the three major ecoregions (Alaska Range, Alaska Peninsula, Lime Hills) that encompass them. Our results provide baseline estimates of relative abundance and models of abundance and species richness relative to land cover that can be used to assess future changes in avian distribution. Additionally, these subarctic montane parks may serve as signals of landscape change and barometers for the assessment of population and distributional changes as a result of warming temperatures and changing precipitation patterns.
