Published: February 2021

Pembiayaan bagi hasil bank syariah terbagi dalam bentuk pembiayaan mudharabah dan musyarakah yang didasarkan pada skema profit sharing atau revenue sharing. Skema ini sangat berbeda dengan kredit pada bank konvensional yang berbasis bunga. Tujuan penelitian adalah untuk menganalisis pengaruh dana pihak ketiga (DPK), financing to deposit ratio (FDR), dan non performing financing (NPF) terhadap pembiayaan bagi hasil perbankan syariah di Indonesia. Penelitian terdiri atas 37 observasi meliputi periode September 2017 sampai dengan September 2020. Data dianalisis dengan metode regresi linier berganda. Penelitian menghasilkan temuan DPK dan FDR berpengaruh positif terhadap pembiayaan bagi hasil, sementara NPF berpengaruh negatif terhadap pembiayaan bagi hasil. Semakin rendah risiko bank, semakin tinggi pengumpulan dana nasabah, dan semakin besar rasio penyaluran pembiayaan berpengaruh terhadap peningkatan penyaluran pembiayaan berbasis bagi hasil pada perbankan syariah di Indonesia.
Abstract
Profit-sharing financing in Islamic banks is divided into mudharabah and musyarakah financing which is based on a profit-sharing or revenue sharing scheme. This scheme is very different from interest-based credit at conventional banks. This study aims to analyze the impact of third party funds (DPK), financing to deposit ratio (FDR), and non-performing financing (NPF) on the profit-sharing financing of Islamic banking in Indonesia. The study consisted of 37 observations covering the period September 2017 to September 2020. Data were analyzed using multiple linear regression methods. The results of the study showed that TPF and FDR had a positive effect on profit-sharing financing, while NPF had a negative effect on profit-sharing financing. The lower bank risk, the higher collection of customer funds, and the higher financing distribution ratio have an effect on increasing the distribution of profit sharing based financing in Islamic banking in Indonesia.

Published: February 2021

The aim of the work was to develop the parameters of the process of salting Pacific herring fillet with a reduced salt content, intended for children’s nutrition. For salting, food salt with a reduced sodium content, enriched with potassium, magnesium, was used. Based on the conducted studies, a rational formulation of the salting mixture was selected, consisting of 5 % salt with a reduced sodium content, 4% sugar, 0.35-0.50% citric acid.
It was found that carrying out the salting process for 72-96 hours provides a low-salted fillet with a salt content of 3.5% with high organoleptic parameters, which are determined by the amino nitrogen content of 110-130 mg/100 g of the product and the buffering capacities of 40-45 degrees.
Short-period Variability in the Globular Cluster NGC 419 and the SMC Field
Authors: Martínez-Vázquez C. E. , Salinas R. , Vivas A. K. 
Published: February 2021

Abstract
Delta Scuti (δ Sct) stars have been extensively studied in our Galaxy but far less in extragalactic systems. Here we study the population of δ Sct variables in NGC 419, an intermediate-age globular cluster of the Small Magellanic Cloud (SMC), using g, r, and i Gemini-S/Gemini Multi-Object Spectrograph (GMOS) time-series observations. Our goal is to study the role of such variables in the cluster extended main-sequence turnoff (MSTO). We report the discovery of 54 δ Sct stars and three eclipsing binaries in the NGC 419 field. We find only a handful of the δ Sct stars at the MSTO of NGC 419, while the majority are fainter, indicating that the cluster is younger (≲1.2 Gyr) than previously thought. Considering their radial distribution, we identify only six δ Sct stars as probable members of NGC 419, while the 48 remaining are likely δ Sct stars of the SMC field. Cluster δ Sct stars appear close to the red edge of the MSTO, supporting the idea that the extended MSTO has its origin in an age spread. The 48 field δ Sct stars represent the largest detection of δ Sct stars made in the SMC. The period distribution of these newly detected δ Sct stars (0.04 day ≲ P ≲ 0.15 day) is similar to that detected in other systems. The amplitude distribution (0.05 mag ≲ Δr ≲ 0.60 mag) is likely biased because of the lack of low-amplitude stars. We finally use the δ Sct stars to calculate distances using different period–luminosity relations. The average distance moduli obtained are 18.76 ± 0.14 mag for NGC 419 and 18.86 ± 0.11 mag for the SMC field, which agree with previous measurements.
The Spiral Galaxies Flat Rotational Velocity Curve Explained by the Constant Group Velocity of a Nonlinear Density Wave
Authors: Vukcevic Miroslava 
Published: February 2021

Abstract
The rotation velocity curves of stars in galaxies, the motions of pairs of galaxies, and the behavior of galaxies in clusters and super-clusters all indicate that there is a lack of mass on different scales in the universe. In this paper, we derive the expression for rotational velocity using the nonlinear density wave theory considering only stellar components and we show that such theory can support the observed flat rotational velocity curve due to the main property of the soliton wave, which is a constant group velocity of the wave. The surface mass density (SMD) function, used to derive gravitational potential gradient and rotational velocity, is not assumed but rather derived as a solution of the nonlinear Srödinger equation, on the contrary to the widely used, in the literature, exponential disk approximation. Three parameters relevant to the curve shape are the intensities of equilibrium SMD, the amplitude of the wave, and total angular velocity or differential rotation, equivalently. Since the shape of the rotational velocity is highly sensitive to the mentioned parameters, this theory eventually provides a method for a very accurate estimation of galaxy mass and angular velocity as well.

Published: February 2021

Abstract
In this paper, we describe a program that identifies in the optical spectrum the main parameters of a spectral line, namely the initial and final wavelengths, and the line depth. Moreover, using numerical calculations, it identifies and removes adjacent lines. Next, the program calculates the equivalent width and the FWHM. The software was tested in a sample of 300 lines in two databases of synthetic spectra generated by the CMFGEN and PoWR codes, and 300 lines in observed spectra from the IACOB database, showing a Gaussian distribution of relative errors, from which it is inferred that 80% of the measured lines have errors less than 17% and only 5% of the lines have errors greater than 26%. The program was also run on the entire database of 45,000 CMFGEN and 202 POWR synthetic spectra, generating a library of H i, He i, and He ii lines necessary to feed the FITspec code for the derivation of stellar parameters: effective temperature, surface gravity, and luminosity.
Probing the Cold Deep Depths of the California Molecular Cloud: The Icy Relationship between CO and Dust

Published: February 2021

Abstract
We study the relationship between molecular gas and dust in the California Molecular Cloud over an unprecedented dynamic range of cloud depth (A
V = 3–60 mag). We compare deep Herschel-based measurements of dust extinction with observations of the 12CO, 13CO, and C18O J = 2 − 1 lines on sub-parsec scales across the cloud. We directly measure the ratio of CO integrated intensity to dust extinction to derive the CO X-factor at over 105 independent locations in the cloud. Confirming an earlier study, we find that no single 12CO X-factor can characterize the molecular gas in the cold (T
dust ≤ 20) regions of the cloud that account for most of its mass. We are able to derive a single-valued X-factor for all three CO isotopologues in the warm (T
dust > 25 K) material that is spatially coincident with an H ii region surrounding the star LkHα 101. We derive the LTE CO column densities for 13CO and C18O since we find both lines are relatively optically thin. In the warm cloud material, CO is completely in the gas phase and we are able to recover the total 13CO and C18O abundances. Using CO abundances and deep Herschel observations, we measure lower bounds to the freeze-out of CO onto dust across the whole cloud, finding some regions having CO depleted by a factor of >20. We construct the first maps of depletion that span the extent of a giant molecular cloud. Using these maps we identify 75 depletion-defined cores and discuss their physical nature.
Effect of Multipole Moments in the Weak Field Limit of a Black Hole Plus Halo Potential
Authors: Dubeibe Fredy L. , Saeed Tareq , Zotos Euaggelos E. 
Published: February 2021

Abstract
In this paper, we consider a Newtonian system whose relativistic counterpart describes a superimposed halo with a black hole. Our aim is to determine how the quadrupole and octupole moments affect the nature of the motion of a test particle, moving in the close vicinity of the black hole. The different types of trajectories for the test particle are mainly classified as bounded, collisional, and escaping, by using modern color-coded basin diagrams. Moreover, an additional analysis is carried out for distinguishing between the different types of bounded motion (regular, sticky, and chaotic). Our results strongly indicate that the multipole moments, along with the total orbital energy, highly affect the final state of the test particle, while at the same time the basin geometry of the phase space tends to be highly dominated by collision and escape orbits.

Abstract
Processes driven by unsteady reconnection can efficiently accelerate particles in many astrophysical plasmas. An example is the reconnection jet fronts in an outflow region. We present evidence of suprathermal ion acceleration between two consecutive reconnection jet fronts observed by the Magnetospheric Multiscale mission in the terrestrial magnetotail. An earthward propagating jet is approached by a second faster jet. Between the jets, the thermal ions are mostly perpendicular to magnetic field, are trapped, and are gradually accelerated in the parallel direction up to 150 keV. Observations suggest that ions are predominantly accelerated by a Fermi-like mechanism in the contracting magnetic bottle formed between the two jet fronts. The ion acceleration mechanism is presumably efficient in other environments where jet fronts produced by variable rates of reconnection are common and where the interaction of multiple jet fronts can also develop a turbulent environment, e.g., in stellar and solar eruptions.
DR 21 South Filament: A Parsec-sized Dense Gas Accretion Flow onto the DR 21 Massive Young Cluster

Published: February 2021

Abstract
DR 21 south filament (DR21SF) is a unique component of the giant network of filamentary molecular clouds in the north region of the Cygnus X complex. Unlike the highly fragmented and star-forming active environment wherein it resides, DR21SF exhibits a coherent profile in the column density map with very few star formation signposts, even though the previously reported linear density of the filament is an order of magnitude higher than the thermal stable threshold. We derive the size (3.6 pc by 0.13 pc), temperature (10–15 K), and mass (1048 M
⊙) of DR21SF from our single-dish observations of NH3 (1, 1) and (2, 2) inversion lines in conjunction with the column density map from our previous work. Star-forming sites are identified along the filament where gas temperature is excessive. We find clear gradients in radial velocity and intrinsic line width along the spine of the filament. The gradients can be well interpreted by a scenario of an accretion flow feeding DR 21 at a mass transfer rate of 1.1 × 10−3
M
⊙ yr−1. Based on the analysis of its kinematic temperature, intrinsic line width, and mass distribution, we conclude that DR21SF is in an overall trans-critical status, which indicates an early evolutionary stage.
Probing the Hot Circumgalactic Medium with Broad O vi and X-Rays

Abstract
Most of the baryonic mass in the circumgalactic medium (CGM) of a spiral galaxy is believed to be warm-hot, with temperature around 106 K. The narrow O vi absorption lines probe a somewhat cooler component at

, but broad O vi absorbers have the potential to probe the hotter CGM. Here we present 376 ks Chandra LETG observations of a carefully selected galaxy in which the presence of broad O vi together with the non-detection of Lyα was indicative of hot gas. The strongest line expected to be present at ≈106 K is O vii
λ21.602. There is a hint of an absorption line at the redshifted wavelength, but the line is not detected with better than 2σ significance. A physical model, taking into account strengths of several other lines, provides better constraints. Our best-fit absorber model has

and

. These parameters are consistent with the hot plasma model based on UV observations; other O vi models of cooler gas phases are ruled out at better than 99% confidence. Thus we have suggestive, but not conclusive evidence for the broad O vi absorber probing the hot gas from the shallow observations of this pilot program. About 800 ks of XMM-Newton observations will detect the expected absorption lines of O vii and O viii unequivocally. Future missions like XRISM, Arcus, and Athena will revolutionize the CGM science.
Evolution of Stellar Feedback in H ii Regions

Published: February 2021

Abstract
Stellar feedback is needed to produce realistic giant molecular clouds and galaxies in simulations, but due to limited numerical resolution, feedback must be implemented using sub-grid models. Observational work is an important means to test and anchor these models, but limited studies have assessed the relative dynamical role of multiple feedback modes, particularly at the earliest stages of expansion when H ii regions are still deeply embedded. In this paper, we use multiwavelength (radio, infrared, and X-ray) data to measure the pressures associated with direct radiation (P
dir), dust-processed radiation (P
IR), photoionization heating (P
H II
), and shock-heating from stellar winds (P
X) in a sample of 106 young, resolved H ii regions with radii ≲0.5 pc to determine how stellar feedback drives their expansion. We find that the P
IR dominates in 84% of the regions and that the median P
dir and P
H II
are smaller than the median P
IR by factors of ≈6 and ≈9, respectively. Based on the radial dependences of the pressure terms, we show that H ii regions transition from P
IR-dominated to P
H II
-dominated at radii of ∼3 pc. We find a median trapping factor of f
trap ∼ 8 without any radial dependence for the sample, suggesting this value can be adopted in sub-grid feedback models. Moreover, we show that the total pressure is greater than the gravitational pressure in the majority of our sample, indicating that the feedback is sufficient to expel gas from the regions.
