Published: July 2022

Работа посвящена изучению адсорбции марганца из водных растворов углеродными материалами. Приведены данные по содержанию соединений марганца в поверхностных и подземных водах Кемеровской области, а также возможные источники его поступления в природные воды. Дан краткий анализ предлагаемых способов деманганации воды. Приведены экспериментальные результаты исследований извлечения Mn (II) из водных сред в условиях равновесия углеродными сорбентами разной ценовой категории, отличающимися исходным сырьем, технологией получения, техническими характеристиками и химическим состоянием поверхности. Установлено, что наибольшее количество марганца извлекается сорбентом АБГ. Полученные изотермы адсорбции проанализированы с использованием теорий мономолекулярной адсорбции (уравнения Фрейндлиха и Ленгмюра), рассчитаны основные адсорбционные параметры. Определено, что модель Ленгмюра описывает изотермы адсорбции марганца с меньшей корреляцией, что позволяет предположить адсорбцию марганца на неоднородных адсорбционных центрах. Оценен приблизительный расход сорбента, необходимый для очистки воды от марганца до нормативных показателей. По совокупности полученных данных для деманганации природных вод предложен углеродный сорбент, высокая адсорбционная емкость которого по отношению к марганцу сочетается с его низкой стоимостью.
The work is devoted to the study of manganese adsorption from aqueous solutions by carbon materials. The data on the concentration of manganese compounds in the surface and underground waters of the Kemerovo Region, as well as possible sources of its entry into natural waters are given. A brief analysis of the proposed methods of water demanganation is given. The experimental results of the studies of Mn (II) extraction from aqueous media under equilibrium conditions with carbon sorbents of different price categories, differing in the raw materials, production technology, technical characteristics and chemical state of the surface, are presented. It has been established that the greatest amount of manganese is extracted by ABG sorbent. The obtained adsorption isotherms were analyzed using the theories of monomolecular adsorption (Freundlich and Langmuir equations); and the main adsorption parameters were calculated. It is determined that the Langmuir model describes manganese adsorption isotherms with a lower correlation, which allows to assume manganese adsorption on heterogeneous adsorption centers. The approximate consumption of the sorbent required to remove manganese from water to the standard values was estimated. Per totality of the data obtained for the demanganation of natural waters, a carbon sorbent is proposed characterized with the high adsorption capacity in relation to manganese and coupled with the low cost.
First-principles study of highly-compressed Sb: a stubborn body-centered cubic structure
Authors: Geshi Masaaki , Funashima Hiroki , Hettiarachchi Gayan Prasad 
Published: July 2022

Abstract
We searched for plausible crystal structures and the entailing electronic profiles of highly-compressed Sb using an originally developed structure-search method and first-principles calculations based on the density functional theory. We report that the experimentally observed highest-pressure (59 GPa) close-packed body-centered cubic (bcc) structure remains the lowest-enthalpy structure at least up to 1000 GPa within the precision of our calculations. Any possibilities of complex structures with many atoms and distortions within the bcc phase, as in the case of the cI16 structure observed for high pressure P, were also safely ruled out. Careful investigations of the density of states (DOS) and phonon dispersions revealed that the bcc structure becomes more stable with increasing pressure. The DOS and phonon dispersions indicate that the stability of the bcc phase increases with increasing pressure. In understanding the strong stability of this stubborn bcc phase, we discuss the phonon and electronic profiles of Sb.
Effect of film thickness on piezoelectric vibrator using hydrothermally synthesized epitaxial (K0.88Na0.12)NbO3 film

Published: July 2022

Abstract
Two types of vibrators using hydrothermally synthesized ferroelectric (K, Na)NbO3 films were fabricated on SrTiO3 substrates. Cantilever piezoelectric vibrators with film thicknesses of 3.5–22.3 μm were used under low-frequency and no resonance drive. The obtained output displacement increased almost linearly as the film thickness increased under both unipolar and bipolar drives. The obtained transverse piezoelectric coefficient, e
31,f, was almost independent of film thickness, ≈−5 C m−2. On the other hand, a longitudinal piezoelectric vibrator was used under the resonance of half-length longitudinal vibration. The electromechanical coupling factor, k
eff
2, and the mechanical quality factor, Q
m, were evaluated. k
eff
2 and Q
m respectively increased from 0.14% to 1.23% and decreased from 556 to 224 as the film thickness increased from 2.5 to 26 μm. By applying a large voltage of 50 V0-p, a large vibration velocity of 1.5 m s−1 was obtained for the vibrator with a film thickness of 26 μm.

The ferroelectricity of wurtzite, Sc

Ga1−x
N (x = 0.35–0.44), was demonstrated in a metal–ferroelectric–metal capacitor. The remanent polarization (P
r) obtained from positive-up negative-down measurements was high, exceeding 120 μC cm−2. The coercive field (E
c) of Sc0.44Ga0.56N was approximately 3.6 MV cm−1 at 300 K, which decreased to 3 MV cm−1 at 473 K. We observed that regardless of the host material, the Sc concentration governed the E
c value in Sc

Abstract
This study aims to find out to study and find out about the application of management in Kebumen Television Training in Central Java Province. The process of collecting data is done through descriptive qualitative research. This research in Central Java Kebumen Television Training was conducted from 22 to 26 July 2019. Based on the results of the study it can be concluded that the application of management in Central Java Kebumen Television Training still needs to be structured in its operations more perfectly so that it will be achieved effectively and efficiently. However, revamping the management function does not necessarily immediately but need time and accuracy, there are still many supporting factors that must be fulfilled, including Human Resources (HR) which is still very limited resulting in many jobs that must be concurrently employed. Thus it is necessary to form a production work relative for each activity so that it will appear to lack human resources and other supporters. This has an impact on the quality of production and broadcast output produced.

A Tertiary Review on Blockchain and Sustainability with Focus on Sustainable Development Goals
Authors: Jiang Shanshan , Jakobsen Kine , Bueie Jonas , Li Jingyue , Haro Peter Halland 
Published: July 2022

<p> Blockchain as a disruptive technology and a driver for social change has exhibited great potential to promote sustainable practices and help organizations and governments achieve the United Nations’ Sustainable Development Goals (SDGs). Literature reviews on blockchain and sustainability exist, but they often focus only on topics related to one or a few SDGs. There is a need to consolidate existing results in terms of SDGs and provide a comprehensive overview of the impacts that blockchain technology may have on each SDG. This paper intends to bridge this gap, presenting a tertiary review based on 34 existing literature reviews, to investigate the relationship between blockchain and sustainability in light of SDGs. The method used is a consensus-based expert elicitation with thematic analysis. The findings include a novel and comprehensive mapping of impact-based interlinkage of blockchain and SDGs and a systematic overview of drivers and barriers to adopting blockchain for sustainability. The findings reveal that blockchain can have a positive impact on all 17 SDGs through technological innovations though some negative effects can occur and impede the achievement of certain objectives. 73 positive and 10 negative linkages between blockchain adoption and the 17 SDGs as well as 45 factors that drive or hinder blockchain adoption for the achievement of SDGs have been identified. Research gaps to overcome the barriers and enhance blockchain’s positive impacts have also been identified. The findings may help managers in evaluating the applicability and tradeoffs and policymakers in making supportive measures to facilitate sustainability using blockchain. </p>
Performance Analysis of DFT and FFT Algorithms on Modern GPUs
Authors: Davuluru Venkata Salini Priyamvada , Hettiarachchi Don Lahiru Nirmal , Balster Eric 
Published: July 2022

<p>Conventionally, the Fast Fourier Transform (FFT) has been adopted over the Discrete Fourier Transform (DFT) due to its faster execution. However, the emergence of modern high performance computing devices has favored the DFT algorithm due to its inherent parallelism. This letter explores a straightforward one-dimensional DFT whose performance is evaluated against the NVIDIA and AMD’s highly optimized FFT libraries, <em>cuFFT</em> and <em>clFFT</em>, respectively. Performance is analyzed in terms of average kernel execution time for data ranging from 2<sup>1</sup> to 2<sup>25</sup> samples across the NVIDIA GeForce GTX 1080 Ti and AMD Radeon RX 6800 XT graphical processors. The DFT algorithm achieves comparable results to the FFT routines for smaller input sizes whereas it significantly outperforms the FFT libraries for larger input lengths. The DFT shows an average performance increase of 177.7% over the <em>cuFFT</em> on the NVIDIA GeForce device using the CUDA toolkit. For the AMD Radeon graphical processor, the DFT outperforms the <em>clFFT</em> by an average of 184.2% using the OpenCL specification. </p>
Two-Inductor Problem
Authors: Barbi Ivo 
Published: July 2022

<p>The behavior of a circuit formed by two inductors magnetically decoupled from each other, with identical inductances or not, associated in parallel with a resistor, is studied in this article. It is shown that when the inductances of the inductors are identical, half of the initial energy is dissipated in the resistor, regardless of its value. For unequal inductances, the energy lost depends on the ratio between the values of the inductances, which can be greater or less than half of the initial energy. It is also shown that, regardless of the circuit parameters, whatever they may be, the algebraic sum of the magnetic fluxes of the two inductors is constant and equal to its initial value, not varying over time along the energy transfer process between the inductors. </p>
A novel back-projection algorithm based on time-delay evaluated by 2-D CFAR
Authors: Gharamohammadi Ali , Shaker George 
Published: July 2022

<p> Imaging algorithms can make the detection of buried objects easier. These algorithms use reflected power from different scatterers with different time delays. Reflected signals from almost perpendicular angles have a significant weight in the imaging algorithms. One additional main feature of these signals is that they have fewer time delays. In this paper, we investigate two parameters that can enhance the back projection (BP) imaging algorithm. The first parameter is the antenna pattern. It controls the ability of radar to sense different angles. The second one is the delays for a point of image based on different locations of radar. It is noticeable that nearfield imaging algorithms suffer from artifacts more than noise. The ground surface clutter can make artifacts more than other clutters. So, clutter cancellation is an important task. The time gating method accomplishes this task better in ultra-wideband (UWB) radars. An experimental setup is used to demonstrate the presented algorithm improvements. </p>
Context-aware Sentiment Analysis on Refined Word Embeddings Word2Vec Model
Authors: Sharma Dr. Archana 
Published: July 2022

<p>This paper proposes a model for the refining of word vectors that does not require a labelled corpus and may be applied to any pre-trained word vectors. The suggested technique employs a sentiment intensity lexicon that may offer realvalued sentiment data to rank a collection of semantically and emotionally related nearest neighbors for each word. The ranking nearest neighbors is then utilized to control the direction and distance of the refinement technique, which iteratively enhances the word vector representation of each word. Experiments using SST demonstrate that the suggested strategy outperformed conventional word embeddings and sentiment embeddings for both coarse-grained and binary sentiment categorization. In addition, the performance of several models of deep neural networks has been enhanced. In future study, the suggested approach will be evaluated on more datasets. Additionally, additional experiments will be undertaken to offer a more comprehensive study. </p>
