STUDY ON INTESTINAL PARASITIC INFECTION AND RELATIONSHIPS BETWEEN THE INFECTIONS AND CORRELATED FACTORS ON SCHOOLCHILDREN AT TRA VINH PROVINCE IN 2017
Authors: Nguyen Anh Huu 
Published: June 2019

The research used a cross-sectional method, which was conducted on 800 primary students in Tap Son primary school and Laboratory school in TraVinh province in order to identify the prevalence of soil-transmitted nematode infections and the relationship between the infection and correlated factors. Stool samples were examined with direct smear method. The rate of intestinal parasitic infection on the primary students in TraVinh province was 4,4%. Of which, Laboratory school had the least rate of intestinal parasitic infection with 0,0%, while Tap Son primary school had the highest rate of intestinal parasitic infection with 8,8%. Hookworm was the predominant nematode (100%), followed Ascarislumbricoides (0,0%), and Trichuristrichiura (0,0%). These relationships show that Tap Son primary environment is heavily polluted with hookworm eggs and that directly behavioral exposure to soil is a risk related to hookworm infections in the community.

Several protection systems of farm animal genetic resources (AnGR) have been elaborated to accomplish conservation programmes. However, conservation practice may differ from region to region even within one country, according to the local environment, climate, agricultural traditions and uniqueness for the region local breeds and ecotypes. The paper introduces the Hungarian protection system, which consists of gene banks, gene protection and gene conservation as main elements of local farm animal breed protection with an important additional element of the system for the Carpathian Basin: gene rescue. It aims to retain all precious heritage of local livestock being out of the scope of the current gene conservation programmes (critically endangered varieties, landraces, ecotypes, specific populations or even individuals with fixed characteristic properties). Next to the brief introduction of the Hungarian protection ystem and HáGK research scopes of AnGR conservation, the authors provide examples of local breeds and ecotypes for which the gene rescue programme have been or should be started in Szeklerland, Transylvania. The programme is called “The Szekler Gene Ring” or in Hungarian “A Székely Géngyur ˝ u”. ˝ Some technical details of the Gene Ring programme are also mentioned. It is concluded that urgent action and the cooperation of breeders, conservationists of related countries are required to start special gene rescue projects with the aim of collecting animals, starting nucleus stock breeding in situ, supporting the existing and elaborating new gene conservation programmes of distinct local breeds and ecotypes traditional for the Carpathian Basin. Introducing cases of general conservation or specific gene rescue programmes that might be useful for other regions and countries, including Southeast Asia, where unique local breeds still exist, can be a further objective of this paper.
Late-time UV Observations of Tidal Disruption Flares Reveal Unobscured, Compact Accretion Disks∗

Published: June 2019

Abstract
The origin of thermal optical and UV emission from stellar tidal disruption flares (TDFs) remains an open question. We present Hubble Space Telescope far-UV (FUV) observations of eight optical/UV-selected TDFs 5–10 yr post-peak. Six sources are cleanly detected, showing point-like FUV emission (

) from the centers of their host galaxies. We discover that the light curves of TDFs from low-mass black holes (<106.5
M
⊙) show significant late-time flattening. Conversely, FUV light curves from high-mass black hole TDFs are generally consistent with an extrapolation from the early-time light curve. The observed late-time emission cannot be explained by existing models for early-time TDF light curves (i.e., reprocessing or circularization shocks), but is instead consistent with a viscously spreading, unobscured accretion disk. These disk models can only reproduce the observed FUV luminosities, however, if they are assumed to be thermally and viscously stable, in contrast to the simplest predictions of α-disk theory. For one TDF in our sample, we measure an upper limit to the UV luminosity that is significantly lower than expectations from theoretical modeling and an extrapolation of the early-time light curve. This dearth of late-time emission could be due to a disk instability/state change absent in the rest of the sample. The disk models that explain the late-time UV detections solve the TDF “missing energy problem” by radiating a rest-mass energy of ∼0.1 M
⊙ over a period of decades, primarily in extreme UV wavelengths.
SDSS J075101.42+291419.1: A Super-Eddington Accreting Quasar with Extreme X-Ray Variability

Abstract
We report the discovery of extreme X-ray variability in a type 1 quasar: SDSS J075101.42+291419.1. It has a black hole (BH) mass of 1.6 × 107
M
⊙ measured from reverberation mapping, and the BH is accreting with a super-Eddington accretion rate. Its XMM-Newton observation in 2015 May reveals a flux drop by a factor of ∼22 with respect to the Swift observation in 2013 May when it showed a typical level of X-ray emission relative to its UV/optical emission. The lack of correlated UV variability results in a steep X-ray-to-optical power-law slope (α
OX) of −1.97 in the low X-ray flux state, corresponding to an X-ray weakness factor of 36.2 at rest-frame 2 keV relative to its UV/optical luminosity. The mild UV/optical continuum and emission-line variability also suggest that the accretion rate did not change significantly. A single power-law model modified by Galactic absorption describes the 0.3–10 keV spectra of the X-ray observations well in general. The spectral fitting reveals steep spectral shapes with Γ ≈ 3. We search for active galactic nuclei (AGNs) with such extreme X-ray variability in the literature and find that most of them are narrow-line Seyfert 1 galaxies and quasars with high accretion rates. The fraction of extremely X-ray variable objects among super-Eddington accreting AGNs is estimated to be ≈15%–24%. We discuss two possible scenarios, disk reflection and partial covering absorption, to explain the extreme X-ray variability of SDSS J075101.42+291419.1. We propose a possible origin for the partial covering absorber, which is the thick inner accretion disk and its associated outflow in AGNs with high accretion rates.

Abstract
Quasi-periodic pulsations (QPPs) are frequently observed in solar flares, which may reveal some essential characteristics of both thermal and nonthermal energy releases. This work presents multi-wavelength imaging observations of an M8.7 flare in active region AR 12242 on 2014 December 17. We found that there were three different QPPs: UV QPPs with a period of about 4 minutes at 1600 Å images near the center of the active region lasting from the preflare phase to the impulsive phase; EUV QPPs with a period of about 3 minutes along the circular ribbon during the preflare phase; and radio QPPs with a period of about 2 minutes at frequencies of 1.2–2.0 GHz around the flaring source region during the impulsive phase. The observations include the radio images observed by the Mingantu Spectral Radioheliograph in China at frequencies of 1.2–2.0 GHz for the first time, microwave images by the Nobeyama Radioheliograph, UV and EUV images by AIA/SDO, and a magnetogram by HMI/SDO. We suggest that the 4 minute UV QPPs should be modulated by the sunspot oscillations, and the 3 minute EUV QPPs are closely related to the 2 minute radio QPPs for their source regions connected by a group of coronal loops. We propose that the intermittent magnetic reconnecting downward and upward plasmoids may be the possible trigger of both the preflare 3 minute EUV QPPs and the impulsive 2 minute radio QPPs. The other possible mechanism is LRC oscillation, which is associated with the current-carrying coronal loops. The latter mechanism implies that the existence of preflare QPPs may be a possible precursor to solar flares.
Secondary Radio and X-Ray Emissions from Galaxy Mergers
Authors: Yuan Chengchao , Murase Kohta , Mészáros Peter 
Published: June 2019

Abstract
Shocks arising in galaxy mergers could accelerate cosmic-ray (CR) ions to TeV–PeV energies. While propagating in the intergalactic medium, these CRs can produce high-energy neutrinos, electron–positron pairs, and gamma-rays. In the presence of intergalactic magnetic fields, the secondary pairs will radiate observable emissions through synchrotron radiation and inverse Compton scattering. In this paper, we demonstrate that these emissions can explain the radio and X-ray fluxes of merging galaxies such as NGC 660 and NGC 3256. Using our model in combination with the observations, we can constrain the gas mass, shock velocity, magnetic field, and the CR spectral index s of these systems. For NGC 660, a single-zone model with a spectral index 2.1 ≲ s ≲ 2.2 is able to simultaneously reproduce the radio and X-ray observations, while a simple one-zone scenario with s ∼ 2 can describe the radio and a large fraction of X-ray observations of NGC 3256. Our work provides a useful approach for studying the dynamics and physical parameters of galaxy mergers, which can play an important part in future multimessenger studies of similar and related extragalactic sources.
A Direct Probe of Mass Density near Inspiraling Binary Black Holes
Authors: Randall Lisa , Xianyu Zhong-Zhi 
Published: June 2019

Abstract
Now that LIGO has revealed the existence of a large number of binary black holes (BHs), identifying their origin has emerged as an important challenge. Observed binary BHs might reside in more isolated regions of the galaxy or alternatively they might be emerging from dense environments such as galactic centers or globular clusters. In the latter case, their center of mass motion as well as their orbital parameters lead to potentially observable changes in the waveforms that would reflect their gravitational interactions with the surrounding matter. The gravitational wave signal would be distinguished by a net phase change or even a time-dependent Doppler shift arising from the orbital motion. We show that this time-dependence might be observable in future space gravitational wave detectors such as LISA that could provide direct information about the BH binary environments and otherwise invisible ambient mass.
A 3 mm Spectral Line Survey toward the Barred Spiral Galaxy NGC 3627

Published: June 2019

Abstract
We conduct spectral line survey observations in the 3 mm band toward a spiral arm, a bar-end, and a nuclear region of the nearby barred spiral galaxy NGC 3627 with the IRAM 30 m telescope and the Nobeyama 45 m telescope. Additional observations are performed toward the spiral arm and the bar-end in the 2 mm band. We detect 8, 11, and 9 molecular species in the spiral arm, the bar-end, and the nuclear region, respectively. Star formation activities are different among the three regions, and in particular, the nucleus of NGC 3627 is known as a low-ionization nuclear emission region/Seyfert 2 type nucleus. In spite of these physical differences, the chemical composition shows impressive similarities among the three regions. This result means that the characteristic chemical composition associated with these regions is insensitive to the local physical conditions such as star formation rate, because such local effects are smeared out by extended quiescent molecular gas on scales of 1 kpc. Moreover, the observed chemical compositions are also found to be similar to those of molecular clouds in our Galaxy and the spiral arm of M51, whose elemental abundances are close to those in NGC 3627. Therefore, this study provides us with a standard template of the chemical composition of extended molecular clouds with the solar metallicity in nearby galaxies.
