Authors: Góralczyk-Bińkowska Aleksandra , Długoński Andrzej , Bernat Przemysław , Długoński Jerzy , Jasińska Anna
Published: December 2021

Textile industry effluents and landfill leachate contain chemicals such as dyes, heavy metals and aromatic amines characterized by their mutagenicity, cytotoxicity and carcinogenicity. The aim of the present study was investigation of the ascomycete fungus N. pironii isolated from urban postindustrial textile green space for its ability to grow and retain metabolic activity in the presence of the dye industry waste. Research focused mainly on dyes, heavy metals and aromatic amines, which had been detected in landfill leachate via HPLC–MS/MS analysis. Presence of all tested compounds as well as leachate in the growth medium clearly favored the growth of fungal biomass. Only slight growth limitation was observed in the presence of 50 mg L-1o-tolidine. The fungus eliminated o-tolidine as well as dyes at all tested concentrations. The presence of metals slightly influenced the decolorization of the azo dyes; however, it was still similar to 90%. During fungal growth, o-tolidine was hydroxylated and/or converted to toluidine and its derivatives. Laccase and cytochrome P450 involvement in this process has been revealed. The results presented in the paper provide a valuable background for the development of a fungus-based system for the elimination of toxic pollutants generated by the textile industry.

Authors: Liu Kuang-Pin , Ma Wei , Li Chun-Yan , Li Li-Yan
Published: December 2021

Treatment of peripheral nerve regeneration with stem cells (SCs) alone has some limitations. For this reason, we evaluate the efficacy of neurotrophic factors combined with stem cell transplantation in the treatment of sciatic nerve injury (SNI) in rats. PubMed, Cochrane Library, Embase, WanFang, VIP and China National Knowledge Infrastructure databases were retrieved from inception to October 2021, and control experiments on neurotrophic factors combined with stem cells in the treatment of SNI in rats were searched. Nine articles and 551 rats were included in the meta-analysis. The results of meta-analysis confirmed that neurotrophic factor combined with stem cells for the treatment of SNI yielded more effective repair than normal rats with regard to sciatic nerve index, electrophysiological detection index, electron microscope observation index, and recovery rate of muscle wet weight. The conclusion is that neurotrophic factor combined with stem cells is more conducive to peripheral nerve regeneration and functional recovery than stem cells alone. However, due to the limitation of the quality of the included literature, the above conclusions need to be verified by randomized controlled experiments with higher quality and larger samples.
A simple modelling on transmission torque of eddy‐current axial magnetic couplings considering thermal effect
Authors: Cheng Xikang , Liu Wei , Luo Weiqi , Sun Minghao , Zhang Yang
Published: December 2021

This paper proposes modelling on the transmission torque of an eddy‐current axial magnetic coupling (EAMC) considering the thermal effect. A new and simple equivalent reluctance network is established to obtain the magnetic flux density based on the two‐dimensional (2D) finite‐element analysis. Furthermore, the expressions of the transmission torque and the thermal loss are derived by establishing the computational coordinate system for the conductor sheet (CS) eddy current. Then, a simple and effective thermal network considering different convective heat transfer modes is presented to obtain the temperature rise, and the influence of temperature on some key parameters is given to correct the transmission torque. Furthermore, the proposed modelling is in good agreement with the three‐dimensional (3D) finite‐element method (FEM) and experiments under normal working conditions. Moreover, some suggestions for the design and optimization of EAMCs are provided.
Two fast and accurate routines for solving the elliptic Kepler equation for all values of the eccentricity and mean anomaly
Authors: Tommasini Daniele , Olivieri David N.
Published: December 2021

Context. The repetitive solution of Kepler’s equation (KE) is the slowest step for several highly demanding computational tasks in astrophysics. Moreover, a recent work demonstrated that the current solvers face an accuracy limit that becomes particularly stringent for high eccentricity orbits.

Aims. Here we describe two routines, ENRKE and ENP5KE, for solving KE with both high speed and optimal accuracy, circumventing the abovementioned limit by avoiding the use of derivatives for the critical values of the eccentricity e and mean anomaly M, namely e > 0.99 and M close to the periapsis within 0.0045 rad.

Methods. The ENRKE routine enhances the Newton-Raphson algorithm with a conditional switch to the bisection algorithm in the critical region, an efficient stopping condition, a rational first guess, and one fourth-order iteration. The ENP5KE routine uses a class of infinite series solutions of KE to build an optimized piecewise quintic polynomial, also enhanced with a conditional switch for close bracketing and bisection in the critical region. High-performance Cython routines are provided that implement these methods, with the option of utilizing parallel execution.

Results. These routines outperform other solvers for KE both in accuracy and speed. They solve KE for every e ∈ [0, 1 − ϵ], where ϵ is the machine epsilon, and for every M, at the best accuracy that can be obtained in a given M interval. In particular, since the ENP5KE routine does not involve any transcendental function evaluation in its generation phase, besides a minimum amount in the critical region, it outperforms any other KE solver, including the ENRKE, when the solution E(M) is required for a large number N of values of M.

Conclusions. The ENRKE routine can be recommended as a general purpose solver for KE, and the ENP5KE can be the best choice in the large N regime.
A novel cosmic filament catalogue from SDSS data
Authors: Carrón Duque Javier , Migliaccio Marina , Marinucci Domenico , Vittorio Nicola
Published: December 2021

Aims.In this work we present a new catalogue of cosmic filaments obtained from the latest Sloan Digital Sky Survey (SDSS) public data.

Methods.In order to detect filaments, we implement a version of the Subspace-Constrained Mean-Shift algorithm that is boosted by machine learning techniques. This allows us to detect cosmic filaments as one-dimensional maxima in the galaxy density distribution. Our filament catalogue uses the cosmological sample of SDSS, including Data Release 16, and therefore inherits its sky footprint (aside from small border effects) and redshift coverage. In particular, this means that, taking advantage of the quasar sample, our filament reconstruction covers redshifts up toz = 2.2, making it one of the deepest filament reconstructions to our knowledge. We follow a tomographic approach and slice the galaxy data in 269 shells at different redshift. The reconstruction algorithm is applied to 2D spherical maps.

Results.The catalogue provides the position and uncertainty of each detection for each redshift slice. The quality of our detections, which we assess with several metrics, show improvement with respect to previous public catalogues obtained with similar methods. We also detect a highly significant correlation between our filament catalogue and galaxy cluster catalogues built from microwave observations of thePlanckSatellite and the Atacama Cosmology Telescope.

Authors: Azwar  , Ichsan Kabullah Muhammad , Zamzami Lucky , Dermawan Rifki
Published: December 2021

The Covid-19 pandemic has had major implications for government administration. Policymakers set policies for handling Covid-19 as a priority agenda at this time. However, these measures have reduced other problems such as stunting which still requires government attention. This article explores policy management of stunting by the local government amid the Covid-19 pandemic with the West Sumatra province case. The findings in the field, show that the implementation of stunting prevention policies is not easy considering the powerlessness caused by budget refocusing and overlapping authorities between institutions. Meanwhile, the meaninglessness is indicated by the low level of public support for the handling of stunting. This is exacerbated by a bureaucratic culture that is slow to implement policies, including in managing stunting-related programs during the Covid-19 crisis. So that there is alienation or what we call as alienation in the bureaucracy in implementing stunting prevention policies. In the end, the management of stunting policies during the Covid-19 pandemic should receive strong support from all involved parties.

Published: December 2021

There has been little discussion to date on air pollution and its potential relationship with health in Makassar, Indonesia. This study aims to create a starting point for this discussion by investigating existing data points and the potential correlation between ambient air pollution and health in Makassar, Indonesia. Six months of air quality data (July-December, 2018) on CO, SO2, NO2, O3, PM10, and PM2.5 were provided by the city and were analyzed alongside tuberculosis and pneumonia data provided by the hospital and community health centers in Makassar. Data were analyzed using principal component analysis, dendrogram, and some GIS mapping. Quantitative data from the USAID-funded Building Health Cities project were also used to help explain some of the quantitative findings. Results show that principal component analysis (PCA) gave three statistics factors having eigenvalues exceeding one, which account for 83% of the total variance in the dataset. The three factors accounted for a strong impact by CO, O3, SO2, PM10, and PM2.5 attributed to the incomplete combustion of fuel from automobiles, bush burning, and industrial emission. Air pollution-related illnesses such as tuberculosis and pneumonia are found to prevail in the area. Real-time air quality monitoring is required to benchmark the health impact of extreme conditions. This study also encourages urgent intervention by decision-makers to tackle the level of tuberculosis and pneumonia occurrence that may be favored by the poor air quality in Makassar.

The waste generation of Padang City at the Final Processing Site (TPA) is 495.50 tons/day, and the amount of unmanaged waste is 62.42 tons/day, of which 40% is plastic waste. Efforts to reduce the use of plastic bags have begun in Padang, referring to Perwaliko number 36 of 2018. Shopping centers and modern stores must use plastic shopping bags that meet SNI no later than December 31, 2020, especially in various retail and contemporary shopping centers. This study aimed to analyze the relationship between the effectiveness of plastic use policies and the decrease in the use of plastic bags in people who shop at modern retailers in Padang City. This type of research is quantitative with a cross-sectional design. The number of samples is 116 respondents who shop at modern shopping centers, namely Matahari Dept. Store, Food Mart Padang, Ramayana Padang and SPAR Padang. Data analysis used univariate and bivariate analysis. The results showed that 46.6% of respondents stated that the plastic bag policy was not adequate, and 46.6% of respondents stated that there was no reduction in plastic bags. There is a significant relationship between the effectiveness of the plastic bag policy and the decrease in the use of plastic bags in the people of Padang City (p=0,029). With this paid plastic bag policy, government, retailers, and the public will be more concerned with the environment.

Authors: Lim Erwin , Kusumastuti Dyah , Rildova  , Asneindra Mario , Sandy Mulyadi Silvester
Published: December 2021

A performance-based evaluation was conducted on an eleven-span reinforced concrete bridge located in a high seismicity area. This bridge was designed using SNI 2833:1992 and to be checked using the updated Indonesian seismic hazard map. In addition, a non-linear time history analysis was conducted using eleven pairs of ground motions to evaluate the structural performance of the bridge pier for the anticipated service life. Elastic analysis shows that the existing bridge still satisfies the strength and serviceability requirement despite the increase in seismic demand. Meanwhile, by evaluating the average inelastic longitudinal reinforcement and concrete strain at bridge pier for selected eleven ground motions, this study suggests that the bridge is still “fully operational” and “life safety” when subjected to the lower level (100 year return period) and upper level (1000 year return period) ground motions, respectively.

Published: December 2021

In this study, we performed research on electromagnetic anomalies related to earthquakes as early signs (precursors) that occurred in Fukushima, Japan on February 13th, 2021. The research focused on the utilization of geomagnetic field data which was derived from the Kakioka (KAK), Kanoya (KNY), and Memambetsu (MMB) observatories, particularly in the ultra-low frequency (ULF) to detect earthquake precursors. The method of electromagnetic data processing was conducted by applying a polarization ratio. In addition, we improved the methodology by splitting the ULF data (which ranged from 0.01-0.1 Hz) into 9 central frequencies and picking up the highest value from each central frequency to get the polarization ratio. The anomaly of magnetic polarization was identified 2-3 weeks before the mainshock in a narrowband frequency in the range of 0.04-0.05 Hz.

Published: December 2021

West Sumatra Province is one of the provinces in Indonesia that is vulnerable to natural disasters, especially earthquakes and tsunamis. Padang city, as the capital city of West Sumatra, is an area that is included in an area with a high level of vulnerability (High Risk Zone) to tsunamis. Therefore, the construction of public buildings such as hospitals, government offices, and school buildings must have certain technical engineering that is able to anticipate the damage and collapse of buildings due to the earthquake and tsunami. One of the public buildings as an educational facility in Padang city is the Elementary School building of the 23/24 (SD 23/24 Padang), located close to the beach. Based on the evaluation results of the Detail Engineering Design (DED) documents, it is found that this building was designed without taking into account the tsunami loads. Therefore, a building assessment should be carried out to check the capacity of the building to resist the working loads, including the tsunami loads, and to investigate the effect of the tsunami loads on the SD 23/24 Padang building. In this study, the building was analyzed using ETABS v.18 software based on the new Indonesian Seismic Code, SNI 1726-2019 for seismic load and FEMA P646-2019 for calculating tsunami loads. The results show that the SD 23/24 Padang building is strong against earthquake loads, but it doesn’t have enough capacity when tsunami loads are applied, in which there are several structural elements (columns/beams) that do not have sufficient capacity to withstand the combined earthquake and tsunami loads. The effect of tsunami loads on the building structure is also discussed in this paper.

Published: December 2021

Pegagan or Centella asiatica is one of the wild plants that has not experienced domestication. Countries in the Eastern have been concerned about conserving medicinal plants to the sustainability of medicinal and aromatic plants. The content of secondary metabolites in Centella asiatica has been known; those are several saponin compounds, including asiaticoside, madeccasoside, and asiatic acid. This study’s goal was to determine the content of secondary metabolites of asiaticoside, madeccasoside and asiatic acid at the top (leaves and petioles) and the bottom (roots and tendrils) with a harvest age of 12 weeks after planting (WAP). The planting site was in the lowlands of Deli Serdang, in which the measuring method used the HPLC tool. According to the results, Centella asiatica, harvested at 12 WAP, had a higher content of asiaticoside and madeccasoside in the roots and tendrils than in the leaves and petioles, while the content of asiatic acid was higher in the leaves and petioles than in the roots and tendrils. The bioactive compounds contained in Pegagan (Centella asiatica) are very efficacious for various diseases. Cultivation is carried out to avoid the loss of germplasm and genetic diversity in nature so that a balance in nature can be achieved.
Reconstructive Principles for the Metacarpal Hand: Case Report
Authors: Escuredo Iker Miguel , Arzua Guillermo Ibarrondo , Gutierrez Juan José García
Published: December 2021

Metacarpal hand is one of the most devastating upper-extremity lesions. We report a case of a multidigit amputation corresponding to a Wei et al.5 IA metacarpal hand in a 56 year-old-male. He underwent a sequential toe-to-hand transfer to the third and fourth radii. Reconstruction of the metacarpal hand, either in an acute or deferred presentation, must consider some reconstructive principles, including the identification of the structures to be spared and the coverage strategies for the acute stage. Toe-to-hand transfer is the preferred technique when replantation is not an option. It is critical to know which structures should be transferred to which positions, as well as to adapt the reconstructive plan to the characteristics from each patient.
Socio-pragmatic potential of (verbo)-visual metaphtonymy in Internet memes featuring Donald Trump
Authors: Martynyuk Alla , Meleshchenko Olga
Published: December 2021

The present study explores (verbo)-visual metaphtonymy in Twitter-based Internet memes featuring Donald Trump, focusing both on the patterns of conceptual interaction of metaphor and metonymy and their socio-pragmatic potential to influence Internet users. The results of the study reveal four types of (verbo)-visual metaphtonymy employed in the analyzed Internet memes. The types are differentiated in accordance with the complexity of the metaphoric source: metaphtonymy with a simple metaphoric source, metaphtonymy with a metaphoric source structured by simple metonymy, metaphtonymy with a metaphoric source structured by metonymic chain, and metaphtonymy with a metaphoric source structured by radial metonymy. In all the four types, the metaphoric target is structured by metonymic amalgam–a metonymic complex in which metonymies that are based on different ICMs merge due to the association of contiguity that is relevant in the current communicative and social/political context. Besides metonymic amalgam, the study introduces the notion of radial metonymy–a metonymic complex that emerges when one metonymic source gives access to several metonymic targets. We argue that the analyzed metaphtonymies rest on conceptual incongruity created to trigger negative evaluative inferences and emotional responses to shape Trump’s image.

Main text

A new key comparison of the standards for air kerma of the National Research Council of Canada (NRC), Canada and the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM in October 2020. The comparison result, based on the calibration coefficients for three transfer chambers and expressed as a ratio of the NRC and the BIPM standards for air kerma, is 1.0022 with a combined standard uncertainty of 2.2 parts in 103. The result agrees within the uncertainties with the indirect comparison carried out in 2009. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.

Active species evolution in the presence of different targets impacted by a helium plasma jet at atmospheric pressure
Authors: Cosimi J , Merbahi N , Marchal F , Eichwald O , Yousfi M
Published: December 2021

A low-temperature plasmas jet is generated by a dielectric barrier discharge powered by a pulsed high voltage in helium flow (3 L min−1) at atmospheric pressure in the presence of different targets (a glass slide, ultra-pure water and a grounded metal plate) positioned perpendicular to the plasma propagation axis. Experimental electrical characterizations such as discharge current, voltage and power, and optical characterizations such as intensified camera ICCD, Schlieren imaging and emission spectroscopy to follow specific excited species have been achieved. The transition from laminar to turbulent regime was observed during the discharge ignition with a larger spreading of the plasma on the surface target with lower dielectric permittivity. The generation of two discharges during each voltage pulse is highlighted during the propagation of the ionization wave which has a variable speed along the plasma axis not depending on the target kind. The evolution of some active species (such as OH, O and excited nitrogen and helium) are investigated using time resolved mapping of the emissions of radiative excited species propagating in ambient air between the plasma jet output and the target. For a low relative permittivity target (glass), the volume ionization wave at its arrival on the target spreads on its surface thus behaving as a surface ionization wave. For the highest relative permittivity (metal), a conductive channel appears between the target surface and the plasma jet during the first discharge, followed by a diffuse plasma plume from the target surface towards the plasma jet after the impact of the ionization wave on the target. A hybrid behavior is highlighted for the ultra-pure water which leads to a short spreading of the ionization wave on the target surface, the formation of a conductive channel in ambient air between tube output and target and the formation of a plasma plume on the target surface.
Hard gluon evolution in the last stage of the bottom-up thermalization
Authors: Ben F G , Machado M V T
Published: December 2021

The study of how fast thermalization in heavy ion collisions occurs has been one of the central topics in the heavy ion community. In the weak coupling picture this thermalization occurs from ‘the bottom up’: high energy partons, formed early in the collision, radiate low energy gluons which then proceed to equilibrate among themselves, forming a thermal bath that brings the high energy sector to equilibrium. In this scheme we apply a model on parton energy loss to discuss the effects of medium expansion on the thermalization problem and estimate the average transverse momentum diffusivity for thermalization in a Bjorken expanding medium.

Published: December 2021

Vanadium selenide (V2Se9) is a true one-dimensional (1D) crystal composed of atomic nanochains bonded by van der Waals (vdW) interactions. Recent experiments revealed the mechanical exfoliation of newly synthesized V2Se9. In this study, we predicted the electronic and transport properties of V2Se9 through computational analyses. We calculated the intrinsic carrier mobility of V2Se9 monolayers (MLs) and nanoribbons (NRs) using density functional theory and deformation potential theory. We found that the electron mobility of the two-dimensional (2D) (010)-plane ML of V2Se9 is highly anisotropic, reaching

The electron mobility of 1D NR systems in a (010)-plane ML of V2Se9 along the chain direction continuously increased as the thickness increased from 1-chain to 4-chain NR (width below 3 nm). Interestingly, the electron mobility of 1D 4-chain NR along the chain direction (

Building resistive switching memory having super-steep switching slope with in-plane boron nitride
Authors: Wang Yisen , Huang Zhifang , Chen Xinyi , Lu Miao
Published: December 2021

The two-dimensional hexagonal boron nitride (h-BN) has been used as resistive switching (RS) material for memory due to its insulation, good thermal conductivity and excellent thermal/chemical stability. A typical h-BN based RS memory employs a metal-insulator-metal vertical structure, in which metal ions pass through the h-BN layers to realize the transition from high resistance state to low resistance state. Alternatively, just like the horizontal structure widely used in the traditional MOS capacitor based memory, the performance of in-plane h-BN memory should also be evaluated to determine its potential applications. As consequence, a horizontal structured resistive memory has been designed in this work by forming freestanding h-BN across Ag nanogap, where the two-dimensional h-BN favored in-plane transport of metal ions to emphasize the RS behavior. As a result, the memory devices showed switching slope down to 0.25 mV dec−1, ON/OFF ratio up to 108, SET current down to pA and SET voltage down to 180 mV.
Role of wave-particle resonance in turbulent transport in toroidal plasmas
Authors: Dong G , Lin Z
Published: December 2021

A clear understanding of wave-particle interaction and associated transport mechanisms of different particle species in the drift wave instabilities is important for accurate modeling and predictions of plasma confinement properties in tokamaks. In particular, the roles of linear resonance and nonlinear scattering in turbulent transport need to be delineated when constructing reduced transport models. First-principle, global gyrokinetic simulations find that electron particle and heat transport decreases to a very low level, while ion heat transport level has no dramatic change when wave-particle resonance is suppressed in the collisionless trapped electron mode (CTEM) turbulence. On the other hand, ion heat transport in the self-consistent ion temperature gradient (ITG) turbulence simulation is qualitatively similar to that in the test-particle simulation using the static ITG turbulence fields. These simulation results show that electron transport is primarily driven by the wave-particle resonance in the CTEM turbulence, and the ion transport is mostly driven by the nonlinear wave-particle scattering in both the CTEM and ITG turbulence.
Current biased gradiometric flux qubit in a circuit-QED architecture
Authors: Kim Mun Dae
Published: December 2021

We propose a scheme for controlling the gradiometric flux qubit (GFQ) by applying an ac bias current in a circuit-QED architecture. The GFQ is insensitive to the magnetic flux fluctuations, which at the same time makes it challenging to manipulate the qubit states by an external magnetic field. In this study, we demonstrate that an ac bias current applied to the α-junction of the GFQ can control the qubit states. Further, the present scheme is robust against the charge fluctuations as well as the magnetic flux fluctuations, promising a long coherence time for quantum gate operations. We introduce a circuit-QED architecture to perform the single and two-qubit operations with a sufficiently strong coupling strength.
