Authors: Hossain Molla Muntasir , Wahab Md Abdul 
Published: January 2019

Introduction: Study in Medical College can act as a contributing factor in developing depression in medical students which may have possible negative academic and professional consequences. Study in any medical course is perceived as being inherently stressful across the globe. Studies on psychological problems such as academic stress, anxiety and depression among medical students have seen that these disorders are under diagnosed and under treated. In this background the present study was carried out with an aim to assess the magnitude of depression and its associated factors in medical students in AFMC.
Objective: To find out the prevalence of depressive symptoms and its associated factors among the students of Armed Forces Medical College (AFMC), Dhaka, Bangladesh.
Materials and Methods: This descriptive type of cross sectional study was carried out in AFMC, Dhaka, Bangladesh for a period from February to April 2014. A total of 211 students studying from 1styear to 4th year MBBS participated in the study. Depression was assessed by Goldberg’s General Health Questionnaire (GHQ-28) and Beck Depression Inventory(BDI) scoring was used to find out the level of depression. BDI scoring 0-10 was considered as normal ups and downs, 11-20 as mild depression, 21-30 as moderate depression, 31-40 as severe depression and more than 40 as extreme depression. Additional questions regarding socio demographic variables were also included. Data analysis was done by software SPSS 19 for windows.
Results: A total of 211 students participated in the study. Among them 86(40.8%) students were reported as having mild to moderate depressive symptoms. Depression was very significantly (p<0.001) higher in 1st year 55(83.3%) than 2nd year 25(38.46%), 3rd year 03(5.45%) and 4th year 03(12%) students. Depression was significantly (p<0.05) higher in Non English Medium background 82(38.8%) than English Medium background 04(1.9%).
Conclusion: Depression may be a significant hidden problem for few of the Medical students and mechanisms to identify and help students with mental health problems should be seriously considered. This calls for in-house counseling service and mentorship program at medical colleges for early detection and treatment of these problems that may help in the improvement of academic performance.

A evolução da ciência da administração possibilitou o surgimento da abordagem direcionada para os recursos humanos na organização, uma vez que, inicialmente, a administração pouco se preocupava com as necessidades manifestas pelas pessoas. Tal característica pode ser observada por meio da descrição histórica da evolução da administração. Nesse sentido, Gil (1994) sustenta que o surgimento da então denominada Administração de Recursos Humanos decorre do crescimento das organizações e do aumento da complexidade das tarefas de gestão de pessoal, sendo que seu desenvolvimento está diretamente relacionado à própria história do desenvolvimento da Teoria Geral da Administração (TGA).Palavras-Chave: Administração.

‘Not a popular personage’: The Factor in Scottish Property Relations, c. 1870–1920
Authors: Cameron Ewen A. 
Published: January 2019

This chapter begins with a detailed examination of the humiliation of a factor on the state-owned Kilmuir estate in north Skye in 1909. It then uses a range of evidence - poetry, journalism, estate papers, government records - to discuss the history and memory of this event. This episode is used as a basis for analysing the wider role of factors in Scottish property relations from 1850 to 1920. Different models of factorship are discussed, as are the varying roles of factors – local estate managers, lawyer consultants – and their subordinates, on the estate and beyond its marches. The chapter has a principal focus on the Scottish Highlands, where debates about the role of the factor were at their most intense, but also notes that property relations in urban Scotland were characterised by some of the same tensions between property owners, factors and tenants.
Search for Sodium-rich Stars among Metal-poor Stars*

Published: January 2019

Abstract
Sodium-rich stars are often found in globular clusters giants. However, some sodium-rich stars have been found among field metal-poor stars. These stars are considered as evaporated from globular clusters. Identified such kind of stars among the field stars in the Galaxy may provide insights of which mechanism was responsible for the ejection from a globular cluster and may reveal some chemical peculiarity. Therefore, we started a search, using high-resolution spectroscopy, among metal-poor stars from several sources of the literature to find a sodium-rich star. Here we present the results for the temperature, gravity, metallicity, and sodium abundances for the stars of our sample. For many of them we determined the temperature, gravity, metallicity, and sodium abundances for the first time. As a result of our search we found one star, CD-23°16310, which has a [Na/Fe] ratio of +1.09. We also show that CD-23°16310 is not a carbon-enhanced metal-poor (CEMP) star since carbon is not enriched but is nitrogen-rich. We did not detect any variation of the radial velocity that would support the hypothesis of mass transfer. Thus, the high sodium and nitrogen abundance could be due to a strong internal mixing process, suggesting that CD-23°16310 is an early asymptotic giant branch star.
Instabilities in the Early Solar System Due to a Self-gravitating Disk
Authors: Quarles B. , Kaib N. 
Published: January 2019

Abstract
Modern studies of the early solar system routinely invoke the possibility of an orbital instability among the giant planets triggered by gravitational interactions between the planets and a massive exterior disk of planetesimals. Previous works have suggested that this instability can be substantially delayed (about hundreds of megayears) after the formation of the giant planets. Bodies in the disk are typically treated in a semi-active manner, wherein their gravitational force on the planets is included, but interactions between the planetesimals are ignored. We perform N-body numerical simulations using GENGA, which makes use of GPUs to allow for the inclusion of all gravitational interactions between bodies. Although our simulated Kuiper Belt particles are more massive than the probable masses of real primordial Kuiper Belt objects, our simulations indicate that the self-stirring of the primordial Kuiper Belt is very important to the dynamics of the giant planet instability. We find that interactions between planetesimals dynamically heat the disk and typically prevent the outer solar system’s instability from being delayed by more than a few tens of megayears after giant planet formation. Longer delays occur in a small fraction of systems that have at least 3.5 au gaps between the planets and planetesimal disk. Our final planetary configurations match the solar system at a rate consistent with other previous works in most regards. Pre-instability heating of the disk typically yields final Jovian eccentricities comparable to the modern solar system’s value, which has been a difficult constraint to match in past works.
Multi-frequency Variability Study of Ton 599 during the High Activity of 2017
Authors: Prince Raj 
Published: January 2019

Abstract
In this work, I have presented a multi-frequency variability and correlation study of the blazar Ton 599, which was observed for the first time in the flaring state at the end of 2017. Data from Fermi-LAT, Swift-XRT/UVOT, Steward observatory, and Owens Valley Radio Observatory(OVRO) (15 GHz) are used and it is found that the source is more variable in γ-rays and optical/UV than in X-rays and radio. Large variations in degree of polarization and position angle are observed during the flaring period. Maximum flux during the γ-ray flare is found to be 12.63 × 10−7 at MJD 58057.5 from the 1 day bin light curve, which is the highest flux ever achieved by this source. It is further found that all the peaks of the flare are very symmetric, which suggests the cooling time of electrons is much smaller than the light-crossing time. Using 1 day as a fast variability time, the size of the γ-ray emission region is estimated as 1.88 × 1016 cm. Two 42 GeV of photons are detected during the flare, which puts a constraint on the location of the emission region, and it is found that the γ-ray emitting blob is located at the outer edge or outside the broad-line region. The trend of increasing fractional variability toward higher energies is also seen. Strong correlations were seen between γ-ray, optical/UV, X-ray, and radio (15 GHz) emission. A small time lag between γ-rays and the optical/UV suggests their emission to be co-spatial, while the lag of 27 days between γ-rays and OVRO (15 GHz) suggests two different emission zones separated by a distance of ∼5 pc.

Published: January 2019

Abstract
We develop a framework for joint constraints on the CO luminosity function based on power spectra (PS) and voxel intensity distributions (VID) and apply this to simulations of CO Mapping Array Pathfinder (COMAP), a CO intensity mapping experiment. This Bayesian framework is based on a Markov chain Monte Carlo (MCMC) sampler coupled to a Gaussian likelihood with a joint PS + VID covariance matrix computed from a large number of fiducial simulations and re-calibrated with a small number of simulations per MCMC step. The simulations are based on dark matter halos from fast peak patch simulations combined with the L
CO(M
halo) model of Li et al. We find that the relative power to constrain the CO luminosity function depends on the luminosity range of interest. In particular, the VID is more sensitive at large luminosities, while the PS and the VID are both competitive at small and intermediate luminosities. The joint analysis is superior to using either observable separately. When averaging over CO luminosities ranging between

, and over 10 cosmological realizations of COMAP Phase 2, the uncertainties (in dex) are larger by 58% and 30% for the PS and VID, respectively, when compared to the joint analysis (PS + VID). This method is generally applicable to any other random field, with a complicated likelihood, as long a fast simulation procedure is available.
Anchoring Magnetic Fields in Turbulent Molecular Clouds. II. From 0.1 to 0.01 pc
Authors: Zhang Y. , Guo Z. , Wang H. H. , Li H-b 
Published: January 2019

Abstract
We compared the magnetic field directions inferred from polarimetry data obtained from 100 pc scale inter-cloud media (ICM) and from subparsec scale molecular cloud cores. The highly correlated result led us to conclude that cloud turbulence must be sub-Alfvénic. Here we extend the study with 0.01 pc cores observed by interferometers. The inferred field directions at this scale significantly deviate from that of the surrounding ICM. An obvious question to ask is whether this high-resolution result contradicts the sub-Alfvénic picture concluded earlier. We performed MHD simulations of a slightly super-critical (magnetic criticality = 2) clouds with Alfvénic Mach number M
A = 0.63 (M

means the average within the entire simulated volume; e.g., Burkhart et al. 2009), which can reproduce the Paper I results, and observed the development toward smaller scales. Interestingly, all subregions hosting cores with n
H2 > 105/cc (the typical density observed by interferometers) possess M
A = 2–3. Not too surprisingly, these slightly super-Alfvénic cores result in B-field orientation offsets comparable to the interferometer observations. The result suggests that gravity can concentrate (and maybe also contribute to, which requires further study to confirm) turbulent energy and create slightly super-Alfvénic cores out of sub-Alfvénic clouds. The results of our simulations also agree with the observed velocity-scale, mass-scale, and field-density relations.

Published: January 2019

Abstract
The PERLAS potential has been successfully used in many studies related to the dynamics of the spiral arms on the equatorial plane of normal (nonbarred) spiral galaxies. In the present work, we extend these studies by investigating the three-dimensional (3D) dynamics of the spiral arms in the same type of potential. We consider a typical open, logarithmic, spiral pattern of pitch angle 25° and we examine the stellar orbits that can support it as the ratio of the masses of the spiral over the disk component (M

d
) varies. We indicate the families of 3D periodic orbits that act as the backbone of the spiral structure and we discuss their stability in the models we present. We study further the quasiperiodic and nonperiodic orbits in general that follow spiral-supporting orbits as the M

s
/M

d
ratio increases. We find that a bisymmetric spiral with 25° pitch angle is better supported by orbits in models with

. In these cases, a strong spiral pattern is supported between the radial 2:1 and 4:1 resonances, whereas local enhancements of the imposed spirals are encountered in some models between 4:1 and corotation. A characteristic barlike structure is observed in all models at radii smaller than the radius of the 2:1 resonance.
A Novel Approach to Constrain Rotational Mixing and Convective-core Overshoot in Stars Using the Initial–Final Mass Relation
Authors: Cummings Jeffrey D. , Kalirai Jason S. , Choi Jieun , Georgy C. , Tremblay P.-E. , Ramirez-Ruiz Enrico 
Published: January 2019

Abstract
The semi-empirical initial–final mass relation (IFMR) connects spectroscopically analyzed white dwarfs (WDs) in star clusters to the initial masses of the stars that formed them. Most current stellar evolution models, however, predict that stars will evolve to WDs ∼0.1 M
⊙ less massive than that found in the IFMR. We first look at how varying theoretical mass-loss rates, third dredge-up efficiencies, and convective-core overshoot may help explain the differences between models and observations. These parameters play an important role at the lowest masses (M
initial < 3 M
⊙). At higher masses, only convective-core overshoot meaningfully affects WD mass, but alone it likely cannot explain neither the observed WD masses nor why the IFMR scatter is larger than observational errors predict. These higher masses, however, are also where rotational mixing in main sequence stars begins to create more massive cores, and hence more massive WDs. This rotational mixing also extends a star's lifetime, making faster-rotating progenitors appear like less massive stars in their semi-empirical age analysis. Applying the observed range of young B-dwarf rotations to the MIST or SYCLIST rotational models demonstrates a marked improvement in reproducing both the observed IFMR data and its scatter. The incorporation of both rotation and efficient convective-core overshoot significantly improves the match with observations. This Letter shows that the IFMR provides a valuable observational constraint on how rotation and convective-core overshoot affect the core evolution of a star.
Boréalisme. Pour un atlas sensible du Nord
Authors: Briens Sylvain 
Published: January 2019

L’article se propose d’établir, en forgeant le terme de boréalisme , un programme de recherche dont l’ambition serait de tracer l’histoire des déplacements, des transformations, des circulations qui se réfèrent au « Nord ». Dépassant la définition d’un boréalisme comme transposition de l’orientalisme, il explore les cadres conceptuels d’un tel programme et croise les outils épistémologiques que les sciences historiques, la géographie, la littérature comparée et plus généralement l’histoire culturelle ont développés dans le domaine de l’histoire des représentations. Le boréalisme apparaît alors comme un cadre pour penser une conceptualité spatiale qui refuse une essentialisation du « Nord » et de l’imaginaire collectif qui lui est associé, et pour saisir un processus dynamique qui redéfinit le « Nord » à chaque énonciation.
Asger Jorn et l’Institut Scandinave de Vandalisme Comparé. La création d’un boréalisme endogène
Authors: Jamet Raphaëlle 
Published: January 2019

Asger Jorn, artiste danois, crée au début des années 1960 l’Institut Scandinave de Vandalisme Comparatif. Que signifie ce projet qui met en relation l’art populaire nordique, l’archéologie et les dernières évolutions de l’avant-garde artistique ? Cet espace hybride peut être difficile à cerner tant il déploie ses activités à travers les frontières à la fois géographiques, conceptuelles et disciplinaires. Le concept de boréalisme , présenté dans cet ouvrage, met en lumière que, par ce projet, Asger Jorn tente d’apporter une réponse complexe à la fois à l’actualité politique, artistique et scientifique. Partant d’une prise de conscience des effets d’une représentation du Nord subie dans un contexte historique et géopolitique mouvementé, il poursuit un travail engagé dans l’avant-garde artistique de l’après-guerre en se réappropriant les concepts de centre et de périphérie pour finalement par le biais de la double figure de l’artiste et du scientifique insuffler une nouvelle puissance et révéler des « Nords » d’ores et déjà présents dans la culture mondiale.
