A teoria pós-colonial e a (re)construção da relação língua e cultura na sala de aula de inglês
Authors: Cristina Barros de Souza Hall Silvia 
Published: April 2020

Este trabalho buscou verificar as percepções que os alunos de duas turmas de Letras- Inglês da UFOPA tinham acerca da relação entre língua e cultura na sala de aula de língua inglesa e em sua formação de futuros professores, mais especificamente, as reflexões (re)construídas e partilhadas na disciplina de Culturas Anglófonas. As atividades dessa disciplina foram planejadas seguindo um viés intercultural, que, de acordo com Corbett (2003), trata todos os valores culturais como abertos ao debate e sujeitos a examinação crítica e negociação. Os resultados do estudo mostraram que, ao se trabalhar a relação cultura e língua à luz da teoria pós-colonial e da pedagogia intercultural, discursos de empoderamento, agência de falantes, possibilidades de resistência e identidades culturais localmente situadas foram identificados nas falas dos participantes

Investigation of the properties of the oral liquid and polymorphism of the MUC5B gene in children with cystic fibrosis
Nazaryan R., Tkachenko M.,Volkova N.
The article presents the study of biophysical and biochemical properties of saliva and polymorphism of the MUC5B protein gene in children with cystic fibrosis. It has been determined that the development of chronic gingivitis in children with cystic fibrosis occurs of the background of a saliva elasticity increasing and of the salivation rate decreasing. The presence of the allele of MUC5B gene with 9 repeats (59 bp) in the intron 36 in the genotype for cystic fibrosis patients is likely to indicate a lower tendency to gingivitis, while among patients possessing the allele with 6 repeats in the genotype the higher percentage of moderately severe gingivitis was detected. These data could be used to predict the development of chronic gingivitis, depending on the genetic polymorphism of the MUC5B gene and to form risk groups for the purpose of differentiated prescribing preventive and therapeutic measures.
Keywords: children, cystic fibrosis, gene polymorphism, gingivitis, oral fluid.

Hajj or pilgrimage is one of the important worship activities for Indonesian Muslims since past. Based on colonial archives, this paper describes thedynamics of the pilgrimage of Indonesia in the colonial period. The long duration of the trip, a tough challenge, and the high cost of travel is a “fee” to be paid by the pilgrims in the past. Moreover, the existence of many service provider of the pilgrimage also influence that dynamics. On the other hand, the colonial government also plays an important role by issuing a variety of regulations to ensure the “order” of the pilgrimage.

Thyristor Controlled Series Compensator based Optimal Reallocation of Generators for Contingency Management
Authors: Kumar B. Sravana , Suryakalavathi M. , Kumar G.V.Nagesh 
Published: April 2020

Privatization of the power industry has made proper utilization of the available resources a compulsory requirement. Optimal power flow (OPF) is an ideal solution to the problem. At the same time, stable operation of the power systems in both normal and contingency condition is of vital importance. Use of FACTS devices is a good method to stop further contingencies in the power system. In this paper, a combined index based strategy for the optimal placement of Thyristor Controlled Series Compensator (TCSC) and optimal tuning of generators using Krill Herd Algorithm has been proposed for contingency management. The contingency analysis has been done using a new method, namely, rapid contingency ranking technique (RCRT). The TCSC has been placed on the basis of an index which is a combination of Line Utilization Factor (LUF) and Fast Voltage Stability Index (FVSI). A multi-objective function has been chosen for tuning the generators. The multi-objective function includes voltage deviation, active power generation cost and transmission line loss. The proposed method has been tested and implemented on an IEEE 30 bus system.

On the Performance of the Layered-Division-Multiplexing using Maximal-Ratio Combining
Authors: Khumyat Tanapong 
Published: April 2020

This article proposes the diversity gain enhancement in layered division multiplexing (LDM) systems by applying maximal-ratio combining (MRC) technique. LDM systems is adopted as a baseline technology of the ATSC 3.0 systems which the two transmission layers are simultaneously transmitted over two different types of fading channels for fixed and mobile services. Hence, the performance analysis of each layer need to be evaluated on different type of fading channel. Starting with the moment generating function (MGF) of the MRC output signal-to-noise ratio (SNR), we propose the new method to derive closed-form expressions for average symbol-error rate (SER) of the proposed systems over Rayleigh and Nakagami-m fading channels in the presence of error propagation (EP) that is generated from the first layer detection. Analytical results show that the specific value of injection level at the transmitter need to be precisely defined to obtain the best mutual benefit for both LDM layers, and the proposed technique has significant performance advantage over conventional LDM systems. Simulation results demonstrate the tightness of the author’s analysis.

As the title implies the article describes essential world problem – financing of terrorism. It is specially noted the role state finance control in the preditictions of financing of terrorism.
During the 21st century the topic of terrorism has become one of the most dangerous and large-scale global challenges to the world community. Since the events of September 11, 2001 in the United States of America, the phenomenon of terrorism has become more violent, bloody and cynical. The number of states that have experienced the horrific consequences of acts of terrorism is on the rise, and in turn, bears human toll, destruction of infrastructure, intimidation of people and more.
The article shows how terrorist organizations are adapting to the current situation and finding new methods and ways of meeting their specific goals with the use of different sources of funding, and what the methods of counteracting them in international practice and in Ukraine.
Also, It draws our attention to to analyze the notion of terrorist financing and international experience in opposing it.

Abstract
We present the transmission spectrum of HAT-P-12b through a joint analysis of data obtained from the Hubble Space Telescope Space Telescope Imaging Spectrograph and Wide Field Camera 3 and Spitzer, covering the wavelength range 0.3–5.0 μm. We detect a muted water vapor absorption feature at 1.4 μm attenuated by clouds, as well as a Rayleigh scattering slope in the optical indicative of small particles. We interpret the transmission spectrum using both the state-of-the-art atmospheric retrieval code SCARLET and the aerosol microphysics model CARMA. These models indicate that the atmosphere of HAT-P-12b is consistent with a broad range of metallicities between several tens to a few hundred times solar, a roughly solar C/O ratio, and moderately efficient vertical mixing. Cloud models that include condensate clouds do not readily generate the submicron particles necessary to reproduce the observed Rayleigh scattering slope, while models that incorporate photochemical hazes composed of soot or tholins are able to match the full transmission spectrum. From a complementary analysis of secondary eclipses by Spitzer, we obtain measured depths of 0.042% ± 0.013% and 0.045% ± 0.018% at 3.6 and 4.5 μm, respectively, which are consistent with a blackbody temperature of 890+60
−70 K and indicate efficient day–night heat recirculation. HAT-P-12b joins the growing number of well-characterized warm planets that underscore the importance of clouds and hazes in our understanding of exoplanet atmospheres.

Abstract
We explore the evolution of a select grid of solar metallicity stellar models from their pre-main-sequence phase to near their final fates in a neutrino Hertzsprung–Russell diagram, where the neutrino luminosity replaces the traditional photon luminosity. Using a calibrated MESA solar model for the solar neutrino luminosity (

We also delineate the contribution of neutrinos from nuclear reactions and thermal processes to the total neutrino loss along the stellar tracks in a neutrino Hertzsprung–Russell diagram. We find, broadly but with exceptions, that neutrinos from nuclear reactions dominate whenever hydrogen and helium burn, and that neutrinos from thermal processes dominate otherwise.
Particle-in-cell Simulations of the Parallel Proton Firehose Instability Influenced by the Electron Temperature Anisotropy in Solar Wind Conditions

Abstract
In situ observations of the solar wind show a limited level of particle temperature anisotropy with respect to the interplanetary magnetic field direction. Kinetic electromagnetic instabilities are efficient to prevent the excessive growth of the anisotropy of particle velocity distribution functions. Among them, the firehose instabilities are often considered to prevent the increase of the parallel temperature and hence to shape the velocity distribution functions of electrons and protons in the solar wind. We present a nonlinear modeling of the parallel firehose instability, retaining a kinetic description for both the electrons and protons. One-dimensional (1D) fully kinetic particle-in-cell simulations using the energy conserving semi-implicit method (ECsim) are performed to clarify the role of the electron temperature anisotropy in the development of the parallel proton firehose instability. We found that in the presence of an electron temperature anisotropy, such that the temperature parallel to the background magnetic field is higher than the temperature in the perpendicular direction, the onset of the parallel proton firehose instability occurs earlier and its growth rate is faster. The enhanced wave fluctuations contribute to the particle scattering reducing the temperature anisotropy to a stable, nearly isotropic state. The simulation results compare well with linear theory. A test case of 1D simulations at oblique angles with respect to the magnetic field is also considered, as a first step to study the cumulative effect of protons and electrons on the full spectrum of instabilities.
Neutron Star Radius-to-mass Ratio from Partial Accretion Disk Occultation as Measured through Fe Kα Line Profiles

Published: April 2020

Abstract
We present a new method to measure the radius-to-mass ratio (R/M) of weakly magnetic, disk-accreting neutron stars by exploiting the occultation of parts of the inner disk by the star itself. This occultation imprints characteristic features on the X-ray line profile that are unique and are expected to be present in low-mass X-ray binary systems seen under inclinations higher than ∼65°. We analyze a Nuclear Spectroscopic Telescope Array observation of a good candidate system, 4U 1636-53, and find that X-ray spectra from current instrumentation are unlikely to single out the occultation features owing to insufficient signal-to-noise. Based on an extensive set of simulations we show that large-area X-ray detectors of the future generation could measure R/M to ∼

% precision over a range of inclinations. Such is the precision in radius determination required to derive tight constraints on the equation of state of ultradense matter and it represents the goal that other methods also aim to achieve in the future.
The Fraction of Gamma-Ray Bursts with an Observed Photospheric Emission Episode

Published: April 2020

Abstract
There is no complete description of the emission physics during the prompt phase in gamma-ray bursts. Spectral analyses, however, indicate that many spectra are narrower than what is expected for nonthermal emission models. Here, we reanalyze the sample of 37 bursts in Yu et al. by fitting the narrowest time-resolved spectrum in each burst. We perform a model comparison between photospheric and synchrotron emission models based on Bayesian evidence. We compare the shapes of the narrowest expected spectra: emission from the photosphere in a non-dissipative flow and slow cooled synchrotron emission from a narrow electron distribution. We find that the photospheric spectral shape is preferred by 54% ± 8% of the spectra (20/37), while 38% ± 8% of the spectra (14/37) prefer the synchrotron spectral shape; three spectra are inconclusive. We hence conclude that GRB spectra are indeed very narrow and that more than half of the bursts have a photospheric emission episode. We also find that a third of all analyzed spectra, not only prefer, but are also compatible with a non-dissipative photosphere, confirming previous similar findings. Furthermore, we notice that the spectra that prefer the photospheric model all have low-energy power-law indices α ≳ −0.5. This means that α is a good estimator for which model is preferred by the data. Finally, we argue that the spectra that statistically prefer the synchrotron model could equally as well be caused by subphotospheric dissipation. If that is the case, photospheric emission during the early, prompt phase would be even more dominant.

Published: April 2020

Abstract
The p–9Be reactions play a key role in accurate prediction of the primordial abundance of beryllium, and its abundance can be used to exquisitely probe the nucleosynthesis and mixing mechanism of stars. In the present work, astrophysical S(E) factors of the 9Be(p, d)8Be and 9Be(p, α)6Li reactions have been obtained from the thick-target yield Yield(E
i) for proton energies from 18 to 100 keV. A full R-matrix analysis was performed to fit both the 9Be(p, α)6Li and 9Be(p, d)8Be reactions simultaneously. The resulting astrophysical S(E) factors agree well with direct measurements, leading to S(0) = 17.3 ± 2.1 and 13.9 ± 1.8 MeV·b for the 9Be(p, α)6Li and 9Be(p, d)8Be reactions, respectively. However, the obtained screening potential (U
s = 512 ± 77 eV) is lower than results of previous work (900 ± 50 and 806 eV), and all of them are larger than the adiabatic limit of 264 eV. The reaction rates were also calculated in the temperature range (0.01–1) ⨯ 109 K, which improves on the precision of the standard database NACRE and NACRE II.
