Authors: Nguyen Minh-Hoa , Tran Van-Tan , Pham Tan-Hung , Cao Thanh-Luu
Published: September 2021

Renewable energy is an emerging candidate in power generation for the compensation of the exhausted fossil fuel, in which wind energy plays an important role. However, how wind farms impact existing power systems has still been a subject on which many researchers are studying. This study has analyzed and evaluated the four wind farms consisting of Ca-Mau (300 MW), Bac-Lieu (99 MW), Soc-Trang (100 MW) and Tra-Vinh (33 MW) located in Southern Vietnam via using the commercial package, WAsP software. Ca-Mau wind farm has the highest planned rated capacity with 51.7% among the wind farms. Each wind farm is built from three different types of wind turbines (1 MW, 2 MW and 3 MW). The estimation has shown that all of the wind farms could produce 2,265 GWh annually, and the 3-MW wind turbines are the most efficient and give the smallest losses for producing wind energy. The wind farms, with respect to environmentally friendly aspects, could avoid 978,544 tCO2 emitted to the environment annually. Additionally, the ETAP program has also been applied to simulate the effects of the proposed wind farms on the national power system including the disturbances from wind speeds, three-phase bus faults, tripping off wind farms and three-phase line faults on the power system. The results show that the wind farms are only slightly impacted.

Spatial Differentiation in Risk Perception and its Impact
on Travel Decisions
Authors: Karl Marion , Mansfeld Yoel
Published: September 2021

This exploratory study adopts a multi-dimensional approach to research
on how travel-related risk perceptions are formed. It looks at risk-inducing
factors both from the tourist and the destination perspectives. Using
predefined risk characteristics observed in the literature, the study's leading
research question asked to what extent these individual risk factors influence
tourists' risk perception. A sample of potential German tourists to Israel was
used for this exploratory study. Each interviewee was asked to indicate his/her
socio-cultural background, travel experience at different spatial levels,
risk-taking personality, level of perceiving Israel as a risky destination, and
willingness to travel to Israel. Results show that accumulated travel
experience does have a bearing on German tourists' willingness to travel to
destinations that carry a high risk image but does not affect the perceived
level of risk. Using the concept of geo-familiarity, the study discovered that
risk perception may not only be developed on a country destination level but
may be different based on spatial perception of risk. Based on these results,
the study draws several risk-management and marketing strategies.

The Relationship Between Air Transport and Rural Tourism in Thailand
Authors: Law Colin C.H.
Published: September 2021

This study used panel to identify the relationship
between air transport and rural tourism in Thailand. The data covered eleven airports
in Thailand from 2009 to 2018 (10 years). The airports are located in the eleven
poorest provinces in the country, based on the gross provincial product per
capita. The study included the total number of air traveler
arrivals as the dependent variable and the total number of flight movements,
provincial tourism revenue and the average monthly income per household as the
independent variables, and used an autoregressive distributed lag model to
identify the relationship between air transport and rural areas in Thailand. The
results of the study indicate that increasing demand for air transport to rural provinces is significantly
and positively generating an increasing
number of flights and a decline in tourism revenue and household income in the eleven
provinces in the long run. The development of the air transport industry alone
is not enough to alleviate the income inequality; it is suggested that
provincial governments need to develop the tourism industry and infrastructure further
to bring greater benefits to society and to reduce income inequality in the
country.

STRATEGI PEMBERDAYAAN EKONOMI KOPERASI SYARI’AH UKHUWAH DALAM MEMBEBASKAN ANGGOTANYA DARI JERATAN RENTENIR
Authors: Samsono Agus , Al Kurni Mufassir
Published: September 2021

Dalam rangka melawan praktek riba yang telah merebak luas, serta upaya untuk membumikan sistem ekonomi Islam, maka didirikanlah lembaga-lembaga keuangan syari’ah. Lembaga keuangan Syari’ah yang tidak terlalu sulit untuk diakses oleh masyarakat menengah ke bawah adalah Koperasi Syari’ah. Di Kota Bekasi, pada tahun 2012 muncul sebuah koperasi syari’ah yang diberi nama Koperasi Syari’ah Ukhuwah Pro Ibu. Salah satu kelebihan yang dimilliki Koperasi Syari’ah Ukhuwah dibandingkan dengan koperasi syari’ah pada umumnya adalah pola pendekatan kelompok dengan konsep grameen bank. Tujuan dari penelitian ini adalah untuk mendeskripsikan strategi pemberdayaan ekonomi yang digunakan oleh Koperasi Syari’ah Ukhuwah dalam membebaskan anggotanya dari jeratan rentenir. Pada penelitian ini penulis menggunakan pendekatan kualitatif dengan jalan studi kasus. Strategi pemberdayaan ekonomi yang dilakukan oleh Koperasi Syari’ah Ukhuwah mampu secara efektif melepaskan anggotanya dari jeratan rentenir, terbukti dari 80% anggota Koperasi yang terjerat rentenir, sekitar 40-60% yang telah diberdayakan, perlahan terlepas dari jeratan rentenir. Hal ini dikarenakan berlepas diri dari jeratan rentenir membutuhkan proses yang cukup panjang. Begitupulaproses pemberdayaan harus dilakukan secara berkelanjutan dalam waktu yang tidak sebentar.

Published: September 2021

We consider the isomonodromic formulation of the Calogero-Painlevé multi-particle systems and proceed to their canonical quantization. We then proceed to the quantum Hamiltonian reduction on a special representation to radial variables, in analogy with the classical case and also with the theory of quantum Calogero equations. This quantized version is compared to the generalization of a result of Nagoya on integral representations of certain solutions of the quantum Painlevé equations. We also provide multi-particle generalizations of these integral representations.
CAN FOUNDERS’DUAL ROLESFACILITATE INNOVATION? – FROM THE PERSPECTIVE OF FOUNDERS’ R&D NETWORK CHARACTERISTICS
Authors: Jiang Yanhui , Wang Danping , Zeng Qianfang
Published: September 2021

Founders are crucial for the start-ups, which in turn makes it very important to study how founders’ behaviour affects the development of the start-ups. Based on the data of the companies listed on Growth Enterprise Market (GEM) and Small & Medium Enterprise (SME) board from 2014 to 2017 in China, this paper explores the impact of founders’ dual roles of R&D and management on enterprises’ innovation performance from the perspective of founders’ R&D network characteristics. The empirical research reveals that the more an enterprise’s founders participate in the R&D activities and the more central they are in the R&D network, the better the enterprise’s technological innovation performance. It is because the high network centrality enables founders the stronger ability of innovation and opportunity identification and draws their attention to innovation. This research further discloses that the promotion effect is restrained when enterprises obtain more government subsidies and founders have more power. Italso finds that founders’ R&D role does not transform the innovation output into enterprises’ value effectively though the role increases the innovation output, instead, it even restrains the transformation.

We present the morphology and stellar population of 27 extremely metal-poor galaxies (EMPGs) at z ∼ 0 with metallicities of 0.01–0.1 Z
⊙. We conduct multicomponent surface brightness (SB) profile fitting for the deep Subaru/Hyper Suprime-Cam i-band images of the EMPGs with the Galfit software, carefully removing the SB contributions of tails. We find that the EMPGs with a median stellar mass of

have a median Sérsic index of n = 1.1 and a median effective radius of r

This moderately large ΔV cannot be explained by the dynamics of the tail, but likely by the infall on the tail. For the first time, we may identify the metal-poor star-forming system just now infalling into the tail.
The Energy Conversion Rate of an Active Region Transient Brightening Estimated by Hinode Spectroscopic Observations
Authors: Kawai Toshiki , Imada Shinsuke
Published: September 2021

We statistically estimate the conversion rate of the energy released during an active region transient brightening to Doppler motion and thermal and nonthermal energies. We used two types of data sets for the energy estimation and detection of transient brightenings. One includes spectroscopic images of Fe xiv, Fe xv, and Fe xvi lines observed by the Hinode/EUV Imaging Spectrometer. The other includes images obtained from the 211 Å channel of the Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA). The observed active region was NOAA 11890 on 2013 November 9 and 10. As a result, the released Doppler motion and nonthermal energies were found to be approximately 0.1%–1% and 10%–100% of the change in the amount of thermal energy in each enhancement, respectively. Using this conversion rate, we estimated the contribution of the total energy flux of AIA transient brightenings to the active region heating to be at most 2% of the conduction and radiative losses.

The X9.3 flare SOL20170906T11:55 was observed by the CsI detector aboard the first Chinese X-ray observatory Hard X-ray Modulation telescope (Insight-HXMT). Using the wavelets method, we report 22 s quasiperiodic pulsations during the impulsive phase. The spectra from 100 keV to 800 keV show the evolution with the gamma-ray flux of a power-law photon index from ∼1.8 before the peak, ∼2.0 around the flare peak, to ∼1.8 again. The gyrosynchrotron microwave spectral analysis reveals a 36.″6 ± 0.″6 radius gyrosynchrotron source with mean transverse magnetic field around 608.2 Gauss. The penetrated ≥10 keV non-thermal electron density is about 106.7 cm−3 at peak time. The magnetic field strength followed the evolution of high-frequency radio flux. Further gyrosynchrotron source modeling analysis implies that there exists a quite steady gyrosynchrotron source, and the non-thermal electron density and transverse magnetic field evolution are similar to higher-frequency light curves. The temporal spectral analysis reveals that those non-thermal electrons are accelerated by repeated magnetic reconnection, likely from a lower corona source.
Collisionless Equilibria in General Relativity: Stable Configurations beyond the First Binding Energy Maximum
Authors: Günther Sebastian , Straub Christopher , Rein Gerhard
Published: September 2021

We numerically study the stability of collisionless equilibria in the context of general relativity. More precisely, we consider the spherically symmetric, asymptotically flat Einstein–Vlasov system in Schwarzschild and maximal areal coordinates. Our results provide strong evidence against the well-known binding energy hypothesis, which states that the first local maximum of the binding energy along a sequence of isotropic steady states signals the onset of instability. We do, however, confirm the conjecture that steady states are stable at least up to the first local maximum of the binding energy. For the first time, we observe multiple stability changes for certain models. The equations of state used are piecewise linear functions of the particle energy and provide a rich variety of different equilibria.
Stellar Mass and Star Formation Rate within a Billion Light-years
Authors: Biteau Jonathan
Published: September 2021

To develop galaxy-targeting approaches, the gravitational-wave community built a catalog of stellar mass in the local universe based on the Two Micron All Sky Survey (2MASS) spectroscopic and photometric redshift surveys. By cleaning and supplementing this catalog, the present work aims to establish a near-infrared flux-limited sample to map both stellar mass and star formation rate (SFR) over the full sky. The 2MASS spectroscopic and photometric redshift surveys are crossmatched with the HyperLEDA database and the Local Volume sample at d < 11 Mpc, providing a flux-limited sample with revised distance estimates and corrections for incompleteness out to 350 Mpc. Scaling relations with stellar mass as a function of morphology are used to construct an SFR cosmography in the local universe. Stellar-mass and SFR densities converge toward values compatible with deep-field observations beyond 100 Mpc. The 3D distribution of these two tracers is consistent with the distribution of matter deduced from cosmic flows. With spectroscopic redshifts available for about half of the ∼400,000 galaxies within 350 Mpc and photometric distances with a 12% uncertainty available for the other half, the present sample may find applications in both cosmology and astroparticle physics. The present work provides, in particular, new bases for modeling the large- and intermediate-scale anisotropies observed at ultra-high energies. The distribution of magnetic fields at megaparsec scales, which can be deduced from the 3D distribution of matter, is inferred to be crucial in shaping the ultra-high-energy sky.
Lightsticks cause adverse effects on behavior and mortality of marine mysids Promysis atlantica
Authors: Cesar-Ribeiro Caio
Published: September 2021

Lightsticks baits are discharged into the ocean after their use in longline fishing. The traditional Brazilian community of Costa dos Coqueiros, Bahia, uses lightsticks as a medicine for rheumatism, vitiligo, and mycoses. It may affect marine life when its content leak into the ocean. This study assessed the toxicity identification and evaluation (TIE) of lightsticks constituents on marine mysids Promysis atlantica. The internal solution was dissolved in seawater with ethanol. The lethal concentration of the contaminant that causes mortality in 50% of the exposed population (LC50) after 3h was 0.001%, demonstrating that lightstick is exceptionally toxic because low concentrations cause mortality to mysids P. atlantica. Due to lightsticks' high toxicity, the TIE baseline was 0.005% SSE (stock solution ethanol), and the selected endpoints were behavior and lethality. The sample submitted to aeration presented a significant reduction (P < 0.05) in toxicity (0.005% SSE) because the volatile compounds caused the toxic effect. The sodium thiosulfate treatment induced an insignificant decrease in toxicity. Thus, a new assay was conducted considering aeration and sodium thiosulfate. This combination reduced lightstick toxicity compared to the baseline lightstick, suggesting that volatile compounds and oxidants were responsible for toxicity; even in low concentrations, lightstick can promote significant behavior changes and deleterious effects. It is recommended to create new mechanisms to inspect fishing vessels, thus avoiding the improper disposal of attractors at sea and common garbage.
