Um estudo retrospectivo de 34 cães com síndrome de dilatação vólvulo-gástrica foi realizado. A idade, raça, procedimentos cirúrgicos e as taxas de mortalidade foram analisados. A raça mais acometida foi o Fila Brasileiro (47,1%) e a idade média dos cães, 8,4 anos. Todos os animais foram submetidos à laparotomia com reposicionamento e descompressão do estômago. A gastrotomia foi realizada em 38,2% dos animais. Dos oito casos com evidência macroscópica de necrose gástrica, sete sofreram ressecção (20,6% dos casos). A gastropexia foi realizada em 61,8%; a esplenectomia, em 23,5% dos cães. A taxa geral de mortalidade verificada foi de 44, I%, sendo 75% nos animais com evidências macroscópicas de necrose gástrica. A grande maioria dos óbitos ocorreu nos dois primeiros dias do pós-operatório. Nos casos em que a gastrotomia e, especialmente, a gastrectomia parcial e esplenectomia foram realizadas, houve um aumento na taxa de mortalidade. A idade não influenciou a taxa de mortalidade.

Abstrak
Pelayanan publik adalah segala kegiatan dalam rangka pemenuhan kebutuhan dasar sesuai hak dasar setiap warga negara dan penduduk atas suatu barang, jasa dan / atau pelayanan administrasi yang disediakan oleh penyelenggara pelayanan yang terkait dengan kepentingan publik. Masyarakat sebagai pelanggan memiliki kebutuhan dan harapan pada kinerja penyelenggara pelayanan publik yang profesional. Tugas Pemerintah Pusat maupun Pemerintah Daerah adalah memberikan pelayanan publik yang mampu memuaskan masyarakat. Implementasi kebijakan desentralisasi dan otonomi daerah di Indonesia mengakibatkan pemerintah daerah mempunyai tanggung jawab dan kewenangan dalam menentukan standar pelayanan minimal. Permasalahan mendasar dalam proses pelayanan publik di Indonesia adalah tentang etika. Tidak ada standar universal tentang norma atau etika serta sanksi yang mengatur secara khusus untuk pelanggaran yang dilakukan aparat dalam pelayanan publik.

Abstract
Public services are all activities in order to fulfill basic needs in accordance with the basic rights of every citizen and resident of an item, service and / or administrative service provided by service providers related to the public interest. Communities as customers have needs and expectations in the performance of professional public service providers. The task of the Central Government and Regional Government is to provide public services that are able to satisfy the public. The implementation of decentralization and regional autonomy policies in Indonesia has resulted in regional governments having responsibility and authority in determining minimum service standards. The fundamental problems in the process of public service in Indonesia are about ethics. There is no universal standard on norms or ethics and sanctions that specifically regulate violations committed by the authorities in public services.

Abstract
Objects gravitationally captured by the Earth–Moon system are commonly called temporarily captured orbiters (TCOs), natural Earth satellites, or minimoons. TCOs are a crucially important subpopulation of near-Earth objects (NEOs) to understand because they are the easiest targets for future sample-return, redirection, or asteroid mining missions. Only one TCO has ever been observed telescopically, 2006 RH
120, and it orbited Earth for about 11 months. Additionally, only one TCO fireball has ever been observed prior to this study. We present our observations of an extremely slow fireball (codename DN160822_03) with an initial velocity of around 11.0 km s−1 that was detected by six of the high-resolution digital fireball observatories located in the South Australian region of the Desert Fireball Network. Due to the inherent dynamics of the system, the probability of the meteoroid being temporarily captured before impact is extremely sensitive to its’ initial velocity. We examine the sensitivity of the fireball’s orbital history to the chosen triangulation method. We use the numerical integrator REBOUND to assess particle histories and assess the statistical origin of DN160822_03. From our integrations we have found that the most probable capture time, velocity, semimajor axis, NEO group, and capture mechanism vary annually for this event. Most particles show that there is an increased capture probability during Earth’s aphelion and perihelion. In the future, events like these may be detected ahead of time using telescopes like the Large Synoptic Survey Telescope, and the pre-atmospheric trajectory can be verified.

Published: October 2019

Abstract
We explore the long-term evolution of a bias-free orbital representation of the cometary nuclei (with diameters above 2 km) of the Kuiper Belt, using the so-called L7 synthetic model from CFEPS, which consists of three dynamical subpopulations: the Classical, the Resonant, and the Scattering. The dynamical evolution of belt particles is studied under the gravitational influence of the Sun and the four giant planets, as well as of the 34 largest known trans-Neptunian objects (i.e., those with H

V
< 4). Here, we indistinctly call Dwarf Planets (DPs) to the full sample of 34 large TNOs. Over a 1 Gyr timescale, we analyze the secular influence of the DPs over Kuiper Belt disk particles and their contribution to the injection rate of new visible Jupiter Family Comets (JFCs). We find that DPs globally increase the number of JFCs by 12.6%, when compared with the comets produced by the giant planets alone. When considering each population separately, we find the increment produced by DPs to be 17%, 12%, and 3% for the Classical, Resonant, and Scattering populations, respectively. Given the rate of escapes from the Kuiper Belt, we find upper limits to the number of objects in each population required to maintain the JFCs in steady state; the results are 55.9 × 106, 78.5 × 106, and 274.3 × 106 for the Scattering, Resonant, and Classical populations, respectively. Finally, we find that the Plutinos are the most important source of comets that were originally in a resonant configuration, where the presence of Pluto alone enhances by 10% the number of JFCs.

Abstract
We present an analysis of the time-averaged spectrum of the Seyfert-2 active galaxy NGC 4388, obtained by NICER. The intrinsic strength of the reflection spectrum in NGC 4388, the large collecting area and favorable passband of NICER, and a net exposure of 105.6 ks yielded an exceptionally sensitive spectrum. Using two independent families of models, the intrinsic spectrum from the central engine is found to be highly obscured but not Compton-thick. Enforcing physical self-consistency within each model, the independent treatments give formally consistent results:

or

. Past measurements made with Suzaku and XMM-Newton are in broad agreement with these column density values. A more recent measurement with NuSTAR (in late 2013) recorded a column density about twice as large; the robustness of this variability is reinforced by the use of consistent models and procedures. The neutral Fe Kα line in the NICER spectrum is nominally resolved and consistent with an origin in the optical broad-line region). The data also require ionized absorption in the Fe K band, similar to the “warm absorbers” detected in Seyfert-1 active galactic nuclei. The low-energy spectrum is consistent with a set of ionized plasma components. We discuss these findings and note that the geometric inferences that derive from this analysis can be tested with XRISM and Athena.
Mitigating Internal Instrument Coupling for 21 cm Cosmology. I. Temporal and Spectral Modeling in Simulations
Authors: Kern Nicholas S. , Parsons Aaron R. , Dillon Joshua S. , Lanman Adam E. , Fagnoni Nicolas , de Lera Acedo Eloy 
Published: October 2019

Abstract
We study the behavior of internal signal chain reflections and antenna cross coupling as systematics for 21 cm cosmological surveys. We outline the mathematics for how these systematics appear in interferometric visibilities and describe their phenomenology. We then describe techniques for modeling and removing these systematics without attenuating the 21 cm signal in the data. This has critical implications for low-frequency radio surveys aiming to characterize the 21 cm signal from the Epoch of Reionization (EoR) and Cosmic Dawn, as systematics can cause bright foreground emission to contaminate the EoR window and prohibit a robust detection. We also quantify the signal loss properties of the systematic modeling algorithms, and show that our techniques demonstrate resistance against EoR signal loss. In a companion paper, we demonstrate these methods on data from the Hydrogen Epoch of Reionization Array as a proof-of-concept.
Multiple-point Modeling the Parker Spiral Configuration of the Solar Wind Magnetic Field at the Solar Maximum of Solar Cycle 24

Published: October 2019

Abstract
By assuming that the solar wind flow is spherically symmetric and that the flow speed becomes constant beyond some critical distance r = R
0 (neglecting solar gravitation and acceleration by high coronal temperature), the large-scale solar wind magnetic field lines are distorted into a Parker spiral configuration, which is usually simplified to an Archimedes spiral. Using magnetic field observations near Mercury, Venus, and Earth during solar maximum of Solar Cycle 24, we statistically surveyed the Parker spiral angles and obtained the empirical equations of the Archimedes and Parker spirals by fitting the multiple-point results. We found that the solar wind magnetic field configurations are slightly different during different years. Archimedes and Parker spiral configurations are quite different from each other within 1 au. Our results provide empirical Archimedes and Parker spiral equations that depend on the solar wind velocity and the critical distance (R
0). It is inferred that R
0 is much larger than that previously assumed. In the near future, the statistical survey of the near-Sun solar wind velocity by Parker Solar Probe can help verify this result.
The Propagation of Flame Fronts through Inhomogeneously Magnetized Plasma
Authors: Remming Ian S. 
Published: October 2019

Abstract
The effects of inhomogeneous magnetic fields on the propagation of magnetohydrodynamical (MHD) laminar flame fronts are investigated. This investigation is motivated by the occurrence of magnetized thermonuclear combustion in astrophysical systems. Magnetized thermonuclear burning occurs on the surfaces of neutron stars during Type I X-ray bursts, within the interiors of white dwarfs during SNe Ia, and during classical novae. Thermonuclear flames that propagate in these systems are expected to travel through inhomogeneous magnetic fields. We present the results of a series of 1.5-dimensional numerical simulations of magnetized flame propagation. A simplified flame model is used with one-step Arrhenius kinetics, an ideal gas equation of state, and constant thermal conductivity coefficients. Although idealized, the model allows for the opportunity to study the physics of the problem without the complexities of the nuclear kinetics of thermonuclear burning. We simulate the propagation of laminar flames through inhomogeneous magnetic media. A changing magnetic medium significantly alters the structure of the flame through the generation of an electric current. The electric current rotates the direction of the magnetic field within the flame and produces strong shear flows. Furthermore, for flames that conduct heat anisotropically and that propagate at an angle 0 < ψ ≲ π/2 to the magnetic field, the flame speed increases due to the nonuniform magnetic field. Naturally occurring flames in astrophysical systems may experience similar changes to their structure and speed that would influence the observational properties of these systems.

Published: October 2019

Abstract
We report an astrochemical study on the evolution of interstellar molecular clouds and consequent star formation in the center of the barred spiral galaxy M83. We used the Atacama Large Millimeter/submillimeter Array (ALMA) to image molecular species indicative of shocks (SiO and CH3OH), dense cores (N2H+), and photodissociation regions (CN and CCH), as well as a radio recombination line (H41α) tracing active star-forming regions. M83 has a circumnuclear gas ring that is joined at two intersections by gas streams from the leading-edge gas lanes on the bar. We found elevated abundances of the shock and dense-core tracers in one of the orbit-intersecting areas, and found peaks of CN and H41α downstream. In the other orbit-intersection area, we found a similar enhancement of the shock tracers, but less variation of other tracers, and no sign of active star formation in the stream. We propose that the observed chemical variation or lack of it is due to the presence or absence of collision-induced evolution of molecular clouds and induced star formation. This work presents the clearest case of the chemical evolution in the circumnuclear rings of barred galaxies thanks to the ALMA resolution and sensitivity.
Flare Activity and Magnetic Feature Analysis of the Flare Stars

Published: October 2019

Abstract
We analyze the light curve of 1740 flare stars to study the relationship between the magnetic feature characteristics and the identified flare activity. Coverage and stability of magnetic features are inspired by rotational modulation of light-curve variations and flare activity of stars are obtained using our automated flare detection algorithm. The results show that: (i) the flare time occupation ratio (or flare frequency) and the total power of flares increase by increasing relative magnetic feature coverage and contrast in F–M-type stars; (ii) magnetic feature stability is highly correlated with the coverage and the contrast of the magnetic structures, as this is the case for the Sun; and (iii) stability, coverage, and contrast of the magnetic features, time occupation ratio, and total power of flares increases for G-, K-, and M-type stars by decreasing the Rossby number due to the excess of the produced magnetic field from dynamo procedure until reaching to the saturation level.

Published: October 2019

Introduction: Seroprevalence of Y. enterocolitica and Y. pseudotuberculosis infections in animals and humans is not established in Pakistan. There are only a few reports on the prevalence of pathogenic Yersinia spp. and infections in small ruminants, however, the role of sheep and goats in the transmission of pathogenic Yersinia remains unclear.
Methodology: A primary survey investigated the presence of anti-Yersinia antibodies among a small population of ruminants detected by recombinant antigen targets in nine government farms dispersed throughout the Punjab province of Pakistan.
Results: Antibodies specific for Y. enterocolitica were detected in 7/9 sheep flocks and in 4/4 goat flocks. Antibodies specific for Y. pseudotuberculosis were detected in 4/9 sheep flocks. Two sheep flocks revealed the presence of both Y. enterocolitica and Y. pseudotuberculosis specific antibodies.
Conclusion: Due to the high number of the population involved in raising small ruminants the risk to veterinary and public health must be rapidly determined.
