    Get PDF
    This paper presents an overview of diminutives in the Bantu language family, with an emphasis on the role of the noun class system in diminutive formation. It charts different processes of language change which have shaped the present-day situation, as well as highlighting instance in which language contact has played a role in the development of diminutive systems. It also addresses semantic and pragmatic processes underlying the change and variation in Bantu diminutives. The comparison is based on a cross-Bantu typology, examining a sample of 48 languages widespread across the linguistic domain

    This research aims to explain why Indonesian Government keep assigning Indonesian workers into Taiwan fisheries ship. Qualitative research with the explanative method is used to explain the correlation between variables. Range of this research is between 2013 and 2016. Interview and literature review used as data collection technique. This research use public policy theory, human rights concept, foreign policy concept, and rational choice theory as analytical tool. The result obtained from this research is there are a reason that benefit the state and society based on domestic and external factors, as well as the social, political, defense and security impacts. So as rationally based on consideration of profit and loss The Government of Indonesia has a reason to keep the Indonesian Workers Placement Policy at Taiwan Fisheries Ship Crew

    Infrared Spectroscopy of GX 1+4/V2116 Oph: Evidence for a Fast Red Giant Wind?

    Get PDF
    We present infrared spectroscopy of the low-mass X-ray binary GX 1+4/V2116 Oph. This symbiotic binary consists of a 2-min accretion-powered pulsar and an M5 III red giant. A strong He I 1.083 micron emission line with a pronounced P Cygni profile was observed. From the blue edge of this feature, we infer an outflow velocity of 250(50) km/s. This is an order of magnitude faster than a typical red giant wind, and we suggest that radiation from the accretion disk or the neutron star may contribute to the acceleration of the outflow. We infer a wind mass loss rate of around 10^-6 Msun/yr. Accretion from such a strong stellar wind provides a plausible alternative to Roche lobe overflow for supplying the accretion disk which powers the X-ray source. The H I Paschen beta and He I 1.083 micron lines showed no evidence for the dramatic changes previously reported in some optical lines, and no evidence for pulsations at the 2-min pulsar period.Comment: 11 pages including 2 PS figures.

    Possible Optical Detection of the Anomalous X-ray Pulsar CXOU J010043.1-721134

    Archival Hubble Space Telescope Wide Field/Planetary Camera 2 observations of the Small Magellanic Cloud serendipitously reveal a possible counterpart to the Anomalous X-ray Pulsar CXOU J010043.1-721134. The candidate is faint, but its location and strange colours make it an interesting object. We estimate, that the probability of such a detection being due to a non-physical source is less than 1.5%. We have tried to confirm the identification with Gemini-South and Magellan, but the conditions were insufficiently favourable. If confirmed, the object will allow the first detailed studies of the optical and ultraviolet emission of magnetars.Comment: 9 pages LaTeX, 2 figures. Accepted for publication in ApJ

    On the Luminosities and Temperatures of Extended X-ray Emission from Planetary Nebulae

    Get PDF
    We examine mechanisms that may explain the luminosities and relatively low temperatures of extended X-ray emission in planetary nebulae. By building a simple flow structure for the wind from the central star during the proto, and early, planetary nebulae phase, we estimate the temperature of the X-ray emitting gas and its total X-ray luminosity. We conclude that in order to account for the X-ray temperature and luminosity, both the evolution of the wind from the central star and the adiabatic cooling of the post-shocked wind's material must be considered. The X-ray emitting gas results mainly from shocked wind segments that were expelled during the early planetary nebulae phase, when the wind speed was moderate. Alternatively, the X-ray emitting gas may result from a collimated fast wind blown by a companion to the central star. Heat conduction and mixing between hot and cool regions are likely to occur in some cases and may determine the detailed X-ray morphology of a nebula, but are not required to explain the basic properties of the X-ray emitting gas.Comment: ApJ, submitted; 16 page

    Drugs trafficking is one of the most salient transnational crimes threateningASEAN member states especially Indonesia and Malaysia. The bilateralcooperation between both countries against transnational drugs trafficking isone of the efforts in combating drug issues happening in those countries.However, the implementation of the cooperation has not effectively reduced thedrugs problem between Indonesia and Malaysia particularly in the years of2009/2010 and 2013/2014. This research aims to observe the strategyestablished by Indonesia and Malaysia in combating drugs offences under thescheme of Drug-Free ASEAN 2015, using the theory of sociological liberalismand SWOT.

    The polar Catalysmic Variable 1RXS J173006.4+033813

    Get PDF
    We report the discovery of 1RXS J173006.4+033813, a polar cataclysmic variable with a period of 120.21 min. The white dwarf primary has a magnetic field of B = 42+6-5 MG, and the secondary is a M3 dwarf. The system shows highly symmetric double peaked photometric modulation in the active state as well as in quiescence. These arise from a combination of cyclotron beaming and ellipsoidal modulation. The projected orbital velocity of the secondary is K2 = 390+-4 km/s. We place an upper limit of 830+-65 pc on the distance.Comment: ApJ Accepted. 12 Pages, 13 Figures, 6 table

    Exit time as a measure of ecological resilience

    Get PDF
    Ecological resilience is the magnitude of the largest perturbation from which a system can still recover to its original state. However, a transition into another state may often be invoked by a series of minor synergistic perturbations rather than a single big one. We show how resilience can be estimated in terms of average life expectancy, accounting for this natural regime of variability. We use time series to fit a model that captures the stochastic as well as the deterministic components. The model is then used to estimate the mean exit time from the basin of attraction. This approach offers a fresh angle to anticipating the chance of a critical transition at a time when high-resolution time series are becoming increasingly available.</p

    Knots in the outer shells of the planetary nebulae IC 2553 and NGC 5882

    Get PDF
    We present images and high-resolution spectra of the planetary nebulae IC 2553 and NGC 5882. Spatio-kinematic modeling of the nebulae shows that they are composed of a markedly elongated inner shell, and of a less aspherical outer shell expanding at a considerably higher velocity than the inner one. Embedded in the outer shells of both nebulae are found several low-ionization knots. In IC 2553, the knots show a point-symmetric distribution with respect to the central star: one possible explanation for their formation is that they are the survivors of pre-existing point-symmetric condensations in the AGB wind, a fact which would imply a quite peculiar mass-loss geometry from the giant progenitor. In the case of NGC 5882, the lack of symmetry in the distribution of the observed low-ionization structures makes it possible that they are the result of in situ instabilities.Comment: 20 pages including 1 table and 6 figures.

    Contact binaries with additional components. III. The adaptive optics detections

    Get PDF
    We present results of the CFHT adaptive optics search for companions of a homogeneous group of contact binary stars, as a contribution to our attempts to prove a hypothesis that these binaries require a third star to become so close as observed. In addition to companions directly discovered at separations of >=1", we introduced a new method of AO image analysis utilizing distortions of the AO diffraction ring pattern at separations of 0.07"-1". Very close companions, with separations in the latter range were discovered in systems HV Aqr, OO Aql, CK Boo, XY Leo, BE Scl, and RZ Tau. More distant companions were detected in V402 Aur, AO Cam, V2082 Cyg. Our results provide a contribution to the mounting evidence that the presence of close companions is a very common phenomenon for very close binaries with orbital periods <1 day.Comment: Full Figs.4 and 5 are in http://www.astro.utoronto.ca/~rucinski/Triples3
