<p><em>The article presents a conceptual analysis of Reconstruction notion which became a conceptual foundation of Ukrainian history in Stalinism era. Through the methodological prism of social engineering, the author studies the lingual techniques of embedding the new era ideological messages into the mental structure of personality. An interesting feature of this research is a comparative analysis of two modernism projects – American reconstruction in 1863–1877 and socio-political breakup of the Stalinism era. The author draws on extensive factual material including J. Stalin’s speeches, Ukrainian scientific periodical publications of 1930s etc. to look into the public and methodological planes of interpreting the Reconstruction construct. The article demonstrates the process of verbal coding for specific fragments or ‘pieces’ of the conceptual system and argues that information manipulation arises at the stage of language-related cognition of the world, interpretation of certain words and their meaning. It is this specifics that leads to creating an informational picture of the world that cannot be constituted without a language and enables an individual to go beyond their direct experience. The article shows the dynamics of implanting the idea of Reconstruction into the concept sphere of Soviet people and its development from the first public presentation of the word in Stalin’s speeches to its entrenchment in scientific discourse. Scholars of the time strived to justify, rationalize and give ground to Stalin’s ideas in terms of building new utopian society systems. Since early 1930s, the Reconstruction concept has been associated with drastic transformations in agriculture, education system, culture and science, mass media and households. In the course of the research the author resorted to general scientific methods of analysis and synthesis, systematization, comparison, as well as conceptual analysis.</em></p><p><strong><em>Key words: </em></strong><em>discourse, concept, reconstruction, Soviet people, social engineering, communication technologies, propaganda.</em></p>

Published: March 2020

Highly stretchable and transparent ionic conducting materials have enabled new concepts of electronic devices denoted as iontronics, with a distinguishable working mechanism and performances from the conventional electronics. However, the existing ionic conducting materials can hardly bear the humidity and temperature change of our daily life, which has greatly hindered the development and real-world application of iontronics. Herein, we design an ion gel possessing unique traits of hydrophobicity, humidity insensitivity, wide working temperature range (exceeding 100°C, and the range covered our daily life temperature), high conductivity (10

S/cm), extensive stretchability, and high transparency, which is among the best-performing ionic conductors ever developed for flexible iontronics. Several ion gel-based iontronics have been demonstrated, including large-deformation sensors, electroluminescent devices, and ionic cables, which can serve for a long time under harsh conditions. The designed material opens new potential for the real-world application progress of iontronics.

We propose the use of gold nanoparticles grown on the surface of nanoporous TiO2 films as Surface Enhanced Raman Scattering (SERS) sensors for the detection of 17β-estradiol. Gold deposition on top of TiO2 surfaces leads to the formation of nanoparticles, which plasmonic properties fit the requirements of a SERS sensor well. The morphological and optical properties of this surface were investigated. Specifically, we demonstrated that the TiO2 background pressure during pulsed laser deposition and annealing conditions enabled the formation of a variety of Au nanoparticles with controlled size, shape and distribution thus resulting in a versatile sensor. We have exploited this surface for the detection of 17β-estradiol, an emerging contaminant in environmental waters. We have found a limit of detection of 10 nM with a sensitivity allowing dynamic range of five orders of magnitude (up to 100 µM).

In the treatment of its fixed assets, PT Bahagia Jaya Sejahtera still has a mismatch. The discrepancy is in the recording of the acquisition price of the fixed assets, the company still records the fixed assets based on the purchase price only, while the costs associated with the fixed assets are charged as costs in the period of occurrence, which are charged as administrative and general costs. In addition to those expenses intended to condition the fixed assets so that they are always ready to be used, recorded as administrative and general expenses in the current period, for example in the purchase of fixed assets in the form of machines, PT Bahagia Jaya does not add these costs to the acquisition price of fixed assets. And when calculating depreciation of fixed assets, companies tend to use the straight-line method, whereas there are other methods that can be used to support the company's earnings. From the results of this analysis, it will be known the comparison of the acquisition price of fixed assets and cost allocation as well as the amount of depreciation costs between the company and the SAK regulations. The results of this analysis are presented in the form of comparative financial statements to determine the effect on financial statements. In the income statement, administrative and general costs are recorded to be too high, due to costs that should add to the acquisition value of fixed assets but instead are allocated to administrative and general costs.Thus, to present financial statements especially in Asset accounting treatment, it should be understood and implemented a fixed accounting policy in accordance with financial accounting standards.

Algunos usos del documental y la memoria: Un estudio de caso en la obra del documentalista cubano Santiago Álvarez.
Authors: Lazo Pasto Orlando Rafael 
Published: March 2020

Resumen: La producción documental a través de la historia del cine ha sido vista desde una dualidad de enfoques, por un lado, como elemento de traducción fiel de una realidad y por otro con una visión que contradice esto, aduciendo que la realidad representada, está matizada por miradas y puntos de vistas. Teniendo como base esta premisa dual, el trabajo tiene como objeto imbricar el carácter del documental, como proceso de reconstrucción de una heredad histórico-espacial, pero también denotando ese espacio sociocultural de signos y significados inserto en un producto audiovisual de corte documental. Para ello se toma como estudio de caso la obra de Santiago Álvarez, documentalista cubano de alta talla a nivel latinoamericano y mundial, que marcó un hito en el desarrollo de este género, por la creatividad sus propuestas documentales.

Published: March 2020

This paper presents frequency response characteristics of a Rogowski coil which is developed with an active integrator. Experiments are performed in a laboratory with a frequency function generator as a source. The frequency responses of the Rogowski coil and the integrator are recorded with both magnitude and phase in order to verify the capability in measuring lightning current waveshapes. For availability in lightning current measurement in the electrical system, the developed Rogowski coil is specifically designed as a clamp on device. The standard lightning current waveshape of the first positive impulse (10/350μs) is simulated to investigate the measuring system. It is found that the frequency bandwidth of the Rogowski coil with the integrator developed in this paper is proper in lightning current measurement.
DFT Study on Interstellar PAH Molecules with Aliphatic Side Groups

Published: March 2020

Abstract
Polycyclic aromatic hydrocarbon (PAH) molecules have been long adjudged to contribute to the frequently detected distinct emission features at 3.3, 6.2, 7.7, 8.6, 11.2, and 12.7 μm with weaker and blended features distributed in the 3–20 μm region. The comparatively weaker 3.4 μm emission feature has been attributed to have an aliphatic origin as carrier. PAH with an aliphatic functional group attached to it is one of the proposed potential candidate carriers for the 3.4 μm emission band, however, the assignment of carrier is still enigmatic. In this work, we employ density functional theory calculation on a symmetric and compact PAH molecule; coronene (C24H12) with aliphatic side group to investigate any spectral similarities with observed features at 3–4 μm. The side groups considered in this study are −H (hydrogenated), −CH3 (methyl), −CH2–CH3 (ethyl), and −CH=CH2 (vinyl) functional groups. Considering the possible presence of deuterium (D) in PAHs, we also include D in the aliphatic side group to study the spectral behavior. We present a detailed analysis of the IR spectra of these molecules and discuss possible astrophysical implications.
On the Formation of PSR J1640+2224: A Neutron Star Born Massive?
Authors: Deng Zhu-Ling , Gao Zhi-Fu , Li Xiang-Dong , Shao Yong 
Published: March 2020

Abstract
PSR J1640+2224 is a binary millisecond pulsar (BMSP) with a white dwarf (WD) companion. Recent observations indicate that the WD is very likely to be a ∼0.7 M
⊙ CO WD. Thus, the BMSP should have evolved from an intermediate-mass X-ray binary (IMXB). However, previous investigations on IMXB evolution predict that the orbital periods of the resultant BMSPs are generally < 40 days, in contrast with the 175 day orbital period of PSR J1640+2224. In this paper, we explore the influence of the mass of the neutron star (NS) and the chemical compositions of the companion star on the formation of BMSPs. Our results show that the final orbital period becomes longer with increasing NS mass, and the WD mass becomes larger with decreasing metallicity. In particular, to reproduce the properties of PSR J1640+2224, the NS was likely born massive (>2.0 M
⊙).

Abstract
We report the discovery of an eclipsing binary millisecond pulsar in the globular cluster M92 (NGC 6341) with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). PSR J1717+4308A, or M92A, has a pulse frequency of 316.5 Hz (3.16 ms) and a dispersion measure of 35.45 pc cm−3. The pulsar is a member of a binary system with an orbital period of 0.20 days around a low-mass companion that has a median mass of ∼0.18 M
⊙. From observations so far, at least two eclipsing events have been observed in each orbit. The longer one lasted for ∼5000 s in the orbital phase range 0.1–0.5. The other lasted for ∼500 s and occurred between 1000 and 2000 s before or after the longer eclipsing event. The lengths of these two eclipsing events also change. These properties suggest that J1717+4308A is a “red-back” system with a low-mass main-sequence or sub-giant companion. Timing observations of the pulsar and further searches of the data for additional pulsars are ongoing.

Abstract
The structure of the electron diffusion region (EDR) in different plasma regimes is an outstanding question related to magnetic reconnection. Here we report a long EDR that extended at least 20 ion inertial lengths downstream of an X line at the Earth’s magnetopause, which was observed by the Magnetospheric Multiscale mission. This EDR was detected in the exhaust of an asymmetric magnetic reconnection with a moderate guide field, the reconnection rate of which was ∼0.1. It corresponds to strong positive energy dissipation (

) and enhancement of electron nongyrotropy. The energy dissipation was contributed by the electron jet and non-ideal electric field along the outflow direction, which suggests that the EDR probably plays more important roles in the energy conversion in magnetic reconnection than previously thought. Our result could be a significant step toward fully understanding the structure of the EDR.
The Birth of Binary Direct-collapse Black Holes
Authors: Latif Muhammad A. , Khochfar Sadegh , Whalen Daniel 
Published: March 2020

Abstract
Supermassive primordial stars forming during catastrophic baryon collapse in atomically cooling halos at z ∼ 15–20 may be the origin of the first quasars in the universe. However, no simulation to date has followed the evolution of these halos at resolutions that are high enough or for times that are long enough to determine if collapse actually produces supermassive stars (SMSs). Here we report new cosmological simulations of baryon collapse in atomically cooled halos for times that are long enough for SMSs to form and die as direct-collapse black holes (DCBHs). We find that the high infall rates required to build up such stars persist until the end of their lives and could fuel the rapid growth of their BHs thereafter. Our simulations also demonstrate that binary and even small multiples of SMSs can form in low-spin and high-spin halos, respectively. This discovery raises the exciting possibility of detecting gravitational waves from DCBH mergers with LISA and tidal disruption events in the near-infrared with the James Webb Space Telescope and ground-based telescopes in the coming decade.
Design and applications of drilling trajectory measurement instrumentation in an ultra-deep borehole based on a fiber-optic gyro
Authors: Liu Yimin , Wang Chenghu , Luo Guangqiang , Ji Weifeng 
Published: March 2020

Abstract. The working environment in hot dry rock boreholes, encountered in deep
geothermal investigation drilling and ultra-deep geological drilling
(up to 5000 m), is very difficult at the present stage. We
have developed a drilling trajectory measuring instrumentation (DTMI),
which is based on the interference fiber-optic gyro (FOG). This can
work continuously, for 4 h, in an environment where the ambient
temperature does not exceed 270 ∘C and the pressure
does not exceed 120 MPa. The DTMI is mainly divided into three
parts: an external confining tube, a metal vacuum flask, and a FOG
measurement probe. Here, we focus on the mechanical design, strength,
and pressure field simulation analysis for the external tube, the
structural design and temperature field simulation analysis for the
vacuum flask, and the FOG Shupe error analysis and compensation in the
temperature field. Finally, through the engineering applications of the
SK-2 east borehole of the China Continental Scientific Drilling
(CCSD) project and the geothermal well of Xingreguan-2, the data
measurements of the drilling trajectory were used to analyze the
stability of the DTMI. The instrument realizes long-duration, high-stability work in the process of making trajectory measurements in an
ultra-deep hole. The instrument has the characteristic of
anti-electromagnetic interference and enables work to be carried out
in the blind zone of existing technologies and instrumentation.
Therefore, DTMI has great potential in the promotion and development
of geological drilling technology.
Groundwater mean residence times of a subtropical barrier sand island

Published: March 2020

Abstract. Fresh groundwater on barrier islands is affected by changing sea levels and precipitation variability due to climate change and is also vulnerable to anthropogenic processes, such as contamination and groundwater over-abstraction. Constraining groundwater mean residence times (MRTs) and flow paths is essential for understanding and managing these resources. This study uses tritium (3H) and carbon-14 (14C) to determine the MRTs of groundwater along a transect across subtropical North Stradbroke Island, south-east Queensland, Australia. Hydraulic properties, major ion geochemistry and stable isotopes are used to validate residence times and to identify the processes responsible for their variability. 3H activities range from less than 0.01 to 1 TU (tritium units), which are values lower than those of local average rainfall (1.6–2.0 TU). 14C concentrations range from 62.5 to 111 pMC (percent modern carbon). Estimated MRTs determined using lumped parameter models and 3H activities range from 37 to more than 50 years. Recharge occurs over the entire island, and groundwater MRTs generally increase vertically and laterally towards the coastal discharge areas, although no systematic pattern is observed. MRTs estimated from 14C concentrations display similar spatial relationships but have a much greater range (from modern to approximately 5000 years). Water diversion and retention by lower-permeability units in the unsaturated parts of the dune systems are the most likely course for relatively long MRTs to date. The results indicate that the internal structures within the dune systems increase MRTs in the groundwater system and potentially divert flow paths. The structures produce perched aquifer systems that are wide-spread and have a significant influence on regional recharge. The geochemical composition of groundwater remains relatively consistent throughout the island, with the only irregularities attributed to old groundwater stored within coastal peat. The outcomes of this study enhance the understanding of groundwater flow, recharge diversion and inhibition for large coastal sand masses in general, especially for older sand masses that have developed structures from pedogenesis and dune movement. With respect to south-east Queensland, it allows the existing regional groundwater flow model to be refined by incorporating independent MRTs to test models' validity. The location of this large fresh groundwater reservoir, in dry and populous south-east Queensland, means that its potential to be used as a water source is always high. Background information on aquifer distribution and groundwater MRTs is crucial to better validate impact assessment for water abstraction.
