PENGARUH GANGGUAN LINGKUNGAN ANTARIKSA PADA SISTEM ELEKTRONIK LAPAN-TUBSAT (EFFECT OF SPACE ENVIRONMENT DISTURBANCE IN LAPAN-TUBSAT SATELLITE)
Authors: Najati Nayla 
Published: March 2018

LAPAN-TUBSAT has been operated more than five years. During the operation, LAPAN-TUBSAT faces several anomaly. It could be observed by using real time telemetry and long time telemetry. When and where an anomaly appeared can be detected with long time telemetry. Anomaly event on LAPAN-TUBSAT’s PCDH is caused by Single Event Latch-Up (SEL) that happen in scale of weeks.These conditions required LAPAN-TUBSAT operators to take action in order to make LAPAN-TUBSAT back to normal operation. This paper describes statistic of SEL that occur in LAPAN-TUBSAT. Almost 70% of SEL event take place at South Atlantic Anomaly (SAA) and the rest at polar.

VERIFICATION OF SCHRENK METHOD FOR WING LOADING ANALYSIS OF SMALL UNMANNED AIRCRAFT USING NAVIERSTOKES BASED CFD SIMULATION
Authors: Soemaryanto Arifin Rasyadi , Rosid Nurhayyan Halim 
Published: March 2018

Prediction of an aerodynamic load acting on a wing or usually called wing loading becomes an important stage for structural analysis. Several methods have been used in estimating the wing loading. Schrenk approximation method is commonly used to achieve the fast estimation of lift distribution along wingspan, but in order to achieve a high level accuracy of aerodynamic prediction, computational fluid dynamics (CFD) with Navier Stokes-based equation can be used. LAPAN Surveillance UAV (LSU series) has been chosen to represent an aerodynamics analysis on generic small unmanned aircraft with twinboom vertical stabilizer configuration. This study was focused to verify the Schrenk approximation method using high accuracy numerical simulation (CFD). The goal of this study was to determine the lift distribution along wingspan and a number of errors between Schrenk approximation and CFD method. In this study, Schrenk approximation result showed similarity with the CFX simulation. So the two results have been verified in analysis of wing loading.

Efficacy of enrofloxacin against transmissible resistance gene (qnrS and aac (6’)-Ib-cr) - containing Escherichia coli isolates and clones
Authors: CENGİZ Murat , ARSLAN Erdem 
Published: March 2018

Aim of this study was to investigate the effects of qnrS1 and aac (6’)-Ib-cr on susceptibility, some pharmacodynamics of enrofloxacin against molecularly constructed and natural isolates of E. coli from animals. The MPCs and mutation frequencies of the drug were determined using the agar dilution method. Time-kill assays were used to determine the antimicrobial activity of the drug against E. coli strains. MPCs of enrofloxacin for qnrS1- and aac(6´)-Ib-cr-containing transformants increased from 0.128 µg/ml to 2 and 4 µg/ml. MPC:MIC ratio of enrofloxacin for transformants and E. coli isolates were 4 and 8, respectively. Mutation frequencies were markedly higher for transformants and isolates compared to control strain. Mutation frequencies diminished up to 6.2x10-18 by increasing the concentrations used in the assay. The results of this study showed that enrofloxacin is less active against E. coli strains in case of additional mutations in QRDR. The concentration-dependent bactericidal effect of enrofloxacin is only observable by the eight times the MIC and increasing concentrations did not alter the bactericidal activity. The combination therapy can be considered to fight with resistant E. coli instead of monotherapy and artificially constructed E. coli strains, which exhibit similar reactions against ENR with natural E. coli isolates, can be used to test the pharmacological efficacy of the combinations.
The Role of Context in Interpreting and Translating the Qur'an
Authors: Haleem M.A.S. Abdel 
Published: March 2018

Quoting out of context can become especially serious when dealing with religious texts. As will be demonstrated in this article, attention to context (siyāq) is essential to proper understanding and translation of the Qur'an. However, in much tafsīr writing, and in most of the translations of the Qur'an into English, as well as more general discussion of the Qur'an, we come across examples where insufficient regard to the context seriously mars understanding and results in misrepresentation of the Qur'an's message. The study of context has a central place in rhetoric (balāgha) and in Qur'anic studies in Arabic, but is hardly mentioned in Qur'anic studies undertaken in English. This article explores the significance of context in reading the Qur'an. In the introduction, I outline the various types of context, and then move on to examine its role in determining the meaning of words and sentences, and in determining the inclusion and omission of material, as well as the order and amount of material used in any given situation in the Qur'an. The discussion will also explore which linguistic features can cause difficulties in determining meaning, and what clues are given in the Qur'an to help identify the context and appropriate meanings of specific passages. Examples will be given from translations of the Qur'an, tafsīr, and Qur'anic studies.
The Faint End of the z = 5 Quasar Luminosity Function from the CFHTLS
Authors: McGreer Ian D. , Fan Xiaohui , Jiang Linhua , Cai Zheng 
Published: March 2018

Abstract
We present results from a spectroscopic survey of z ∼ 5 quasars in the CFHT Legacy Survey. Using both optical color selection and a likelihood method, we select 97 candidates over an area of 105 deg2 to a limit of i
AB < 23.2, and 7 candidates in the range 23.2 < i
AB < 23.7 over an area of 18.5 deg2. Spectroscopic observations for 43 candidates were obtained with Gemini, MMT, and Large Binocular Telescope, of which 37 are z > 4 quasars. This sample extends measurements of the quasar luminosity function ∼1.5 mag fainter than our previous work in Sloan Digital Sky Survey Stripe 82. The resulting luminosity function is in good agreement with our previous results, and suggests that the faint end slope is not steep. We perform a detailed examination of our survey completeness, particularly the impact of the Lyα emission assumed in our quasar spectral models, and find hints that the observed Lyα emission from faint z ∼ 5 quasars is weaker than for z ∼ 3 quasars at a similar luminosity. Our results strongly disfavor a significant contribution of faint quasars to the hydrogen-ionizing background at z = 5.
Absolute Dimensions and Evolutionary Status of the Semi-detached Algol W Ursae Minoris

Published: March 2018

Abstract
Double-lined eclipsing binaries allow accurate and direct determination of fundamental parameters such as mass and radius for each component, and they provide important constraints on the stellar structure and evolution models. In this study, we aim to determine a unique set of binary parameters for the Algol system W UMi and to examine its evolutionary status. New high-resolution time-series spectroscopic observations were carried out during 14 nights from 2008 April to 2011 March, and a total of 37 spectra were obtained using the Bohyunsan Optical Echelle Spectrograph. We measured the radial velocities (RVs) for both components, and the effective temperature of the primary star was found to be T
eff,1 = 9310 ± 90 K by a comparison of the observed spectra and the Kurucz models. The physical parameters of W UMi were derived by an analysis of our RV data together with the multi-band light curves of Devinney et al. The individual masses, radii, and luminosities of both components are M
1 = 3.68 ± 0.10 M
⊙ and M
2 = 1.47 ± 0.04 M
⊙, R
1 = 3.88 ± 0.03 R
⊙ and R
2 = 3.13 ± 0.03 R
⊙, and L
1 = 102 ± 1 L
⊙ and L
2 = 7.3 ± 0.1 L
⊙, respectively. A comparison of these parameters with theoretical stellar models showed that the primary component lies in the main-sequence band, while the less massive secondary is noticeably evolved. The results indicate that the initially more massive star became the present secondary by losing most of its own mass via mass transfer to the companion (present primary).

Abstract
We present a multiwavelength analysis of 48 submillimeter galaxies (SMGs) detected in the Large APEX Bolometer Camera/Atacama Cosmology Telescope (ACT) Survey of Clusters at All Redshifts, LASCAR, which acquired new 870 μm and Australia Telescope Compact Array 2.1 GHz observations of 10 galaxy clusters detected through their Sunyaev–Zel’dovich effect (SZE) signal by the ACT. Far-infrared observations were also conducted with the Photodetector Array Camera and Spectrometer (100/160 μm) and SPIRE (250/350/500 μm) instruments on Herschel for sample subsets of five and six clusters. LASCAR 870 μm maps were reduced using a multiscale iterative pipeline that removes the SZE increment signal, yielding point-source sensitivities of σ ∼ 2 mJy beam−1. We detect in total 49 sources at the 4σ level and conduct a detailed multiwavelength analysis considering our new radio and far-IR observations plus existing near-IR and optical data. One source is identified as a foreground galaxy, 28 SMGs are matched to single radio sources, four have double radio counterparts, and 16 are undetected at 2.1 GHz but tentatively associated in some cases to near-IR/optical sources. We estimate photometric redshifts for 34 sources with secure (25) and tentative (9) matches at different wavelengths, obtaining a median

. Compared to previous results for single-dish surveys, our redshift distribution has a comparatively larger fraction of sources at z > 3, and the high-redshift tail is more extended. This is consistent with millimeter spectroscopic confirmation of a growing number of high-z SMGs and relevant for testing of cosmological models. Analytical lens modeling is applied to estimate magnification factors for 42 SMGs at clustercentric radii >1.′2; with the demagnified flux densities and source-plane areas, we obtain integral number counts that agree with previous submillimeter surveys.
New Constraints on the Geometry and Kinematics of Matter Surrounding the Accretion Flow in X-Ray Binaries from Chandra High-energy Transmission Grating X-Ray Spectroscopy
Authors: Tzanavaris P. , Yaqoob T. 
Published: March 2018

Abstract
The narrow, neutral Fe Kα fluorescence emission line in X-ray binaries (XRBs) is a powerful probe of the geometry, kinematics, and Fe abundance of matter around the accretion flow. In a recent study it has been claimed, using Chandra High-Energy Transmission Grating (HETG) spectra for a sample of XRBs, that the circumnuclear material is consistent with a solar-abundance, uniform, spherical distribution. It was also claimed that the Fe Kα line was unresolved in all cases by the HETG. However, these conclusions were based on ad hoc models that did not attempt to relate the global column density to the Fe Kα line emission. We revisit the sample and test a self-consistent model of a uniform, spherical X-ray reprocessor against HETG spectra from 56 observations of 14 Galactic XRBs. We find that the model is ruled out in 13/14 sources because a variable Fe abundance is required. In two sources a spherical distribution is viable, but with nonsolar Fe abundance. We also applied a solar-abundance Compton-thick reflection model, which can account for the spectra that are inconsistent with a spherical model, but spectra with a broader bandpass are required to better constrain model parameters. We also robustly measured the velocity width of the Fe Kα line and found FWHM values of up to ∼5000 km s−1. Only in some spectra was the Fe Kα line unresolved by the HETG.
Formation of the First Star Clusters and Massive Star Binaries by Fragmentation of Filamentary Primordial Gas Clouds
Authors: Hirano Shingo , Yoshida Naoki , Sakurai Yuya , Fujii Michiko S. 
Published: March 2018

Abstract
We perform a set of cosmological simulations of early structure formation incorporating baryonic streaming motions. We present a case where a significantly elongated gas cloud with ∼104 solar mass (M
⊙) is formed in a pre-galactic (∼107
M
⊙) dark halo. The gas streaming into the halo compresses and heats the massive filamentary cloud to a temperature of ∼10,000 Kelvin. The gas cloud cools rapidly by atomic hydrogen cooling, and then by molecular hydrogen cooling down to ∼400 Kelvin. The rapid decrease of the temperature and hence of the Jeans mass triggers fragmentation of the filament to yield multiple gas clumps with a few hundred solar masses. We estimate the mass of the primordial star formed in each fragment by adopting an analytic model based on a large set of radiation hydrodynamics simulations of protostellar evolution. The resulting stellar masses are in the range of ∼50–120 M
⊙. The massive stars gravitationally attract each other and form a compact star cluster. We follow the dynamics of the star cluster using a hybrid N-body simulation. We show that massive star binaries are formed in a few million years through multi-body interactions at the cluster center. The eventual formation of the remnant black holes will leave a massive black hole binary, which can be a progenitor of strong gravitational wave sources similar to those recently detected by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO).
