Published: November 2022

Distributed acoustic sensing (DAS) is an emerging technology that offers great potential in the high-resolution multi-scale seismic investigation due to its dense spatial coverage and cost-effectiveness. However, DAS data notoriously suffer from the low signal-to-noise ratio (SNR) due to various types of strong noise, for example, high-frequency noise, high-amplitude erratic noise, vertical or horizontal noise. Here, we propose a novel denoising framework by cascading several individual denoising methods that are designed for suppressing specific types of noise. First, to suppress the high-frequency noise, we apply a bandpass filter, which is implemented by recursive infinite impulse response filtering in the time domain. Second, to suppress the erratic noise, we apply a structure-oriented median filter that arises from the reflection seismology field. Finally, to suppress the vertical or horizontal noise, we apply a carefully designed dip filter in the frequency–wavenumber domain. The overall effect of these cascaded denoising steps is that the DAS data can be dramatically improved in terms of SNR. We introduce in detail the implementations of each step in the proposed denoising framework and analyze their respective contribution toward the final improvement. We demonstrate the effectiveness of the proposed denoising framework through the open-access Frontier Observatory for Research in Geothermal Energy (FORGE) geothermal DAS dataset and provide the reproducible processing workflows for all the DAS subsets containing the catalog earthquake and microseismic events.

Authors: K Sunda Mukesh , Chauhan Kanchan , Dr Rajeev , Boliwal Krishna
Published: November 2022

Etomidate is a hypnotic drug used as an intravenous anaesthetic induction agent. Etomidate causes myoclonic movements in 50-80% patients after induction which makes it less desirable for induction. Aim: Present study was to determine the effect of priming in preventing myoclonic movements after intravenous injection with etomidate in adult patients undergoing cardiac surgery. Materials and Methods: 108 patients ASA grade III scheduled for elective cardiac surgery were allocated randomly in two groups- Group A (n=54): Patients received induction dose of 0.3mg/kg I.V. etomidate, Group B (n=54): Patients received a priming dose of 0.03mg/kg etomidate I.V. followed after 1 minute by induction dose of 0.3 mg/kg I.V. etomidate over 20 seconds. 3 minutes after the start of induction with etomidate, patients in both groups were given injection fentanyl 4mcg/kg followed by injection Rocuronium (1mg/kg bodyweight) to facilitate tracheal intubation. The occurrence and intensity of myoclonus were observed for 3 min from the start of injection of the induction dose and graded clinically by a blinded observer as: 0=no myoclonus, 1=mild myoclonus, 2=moderate myoclonus and 3=severe myoclonus. Result: The average dose of etomidate used during induction and demographic variables were similar in both the groups. The incidence of myoclonus in priming Group (27/54 [50%] was significantly lower than in control Group (45/54 [83.33%].Myoclonus of moderate or severe grade occurred in significantly more patients in control Group (68.3%) than in priming Group (36.5%).Conclusion: Pre-treatment with etomidate (0.03 mg/kg), given 60 seconds before induction of anaesthesia is more effective in reducing the incidence of etomidate-induced myoclonus without related side-effects.

Published: November 2022

Энергетика – чрезвычайно интересная область, которая стремительно развивается уже много лет подряд. Сегодня публикуются самые разные статьи об альтернативных источниках энергии, аккумуляторах и суперконденсаторах. Эта статья о литий-ионном аккумуляторе. Аккумуляторы состоят из трех отдельных частей, одна из которых является анодом. Именно в этой области скапливаются электроны, обеспечивающие питание электрических устройств. С 2011 года в литиевых батареях чаще всего используются графитовые аноды. Обладая потенциалом удерживать во много раз больше энергии, чем графит, кремний является заманчивым предложением для ученых, работающих над литиевыми батареями следующего поколения. Кремний является перспективным материалом для анодов литий-ионных аккумуляторов нового поколения, так как в процессе электрохимического введения способен накапливать большое количество лития (до 4,4 атома Li на атом Si) и обеспечивать очень высокие значения удельной емкости (4200 мАч/г). В настоящей статье рассмотрены перспективы использования кизельгура (ДЭ) (Мугалжарского района) в секторе непрерывного развития энергетической науки и техники. Экологически чистый диоксид кремния и производства кремния, кизельгур имеет необходимую нано-микроструктуру, которая предлагает преимущества, присущие существующим и новым приложениям в электрохимии, катализе, оптоэлектронике и биомедицинской инженерии. Было обнаружено, что кремний, и материалы на основе кремния полезны для хранения и накопления энергии. Также для сравнения поверхность ДЭ была модифицирована нанотрубками. Электродный материал был охарактеризован методами EDAX, SEM, BET и электрохимическими методами. Полученные результаты показали преимущество модифицированного диатомита (удельная поверхность – 188,9 м2/г и удельная емкость аккумулятора – 120 мА·ч/г) по сравнению с немодифицированным (удельная поверхность – 39,1 м2/г и удельная емкость аккумулятора) – 100 мАч/г).

Published: November 2022

The dissolution of bituminous coal at mild temperature was studied using a variety of commercially available coal- and petroleum-derived hydrocarbon fractions, hydrorefined derivatives and blends as solvents. The chemical and molecular composition of the coal, solvents and extracts were characterized by chemical and group analyses, and by IRFT, 1H NMR, GC-MS and liquid chromatography. Low volatile solvents like highly aromatic coal tar (CT), its anthracene fraction (AFCT), petroleum-derived solvent (HGOCC) and binary blends were found to exhibit high performance for coal dissolution into quinoline solubles (to 79‒82%), and the yields of gases being no more than 0.5%. The extracts obtained using CT and AFCT solvents represented pitch-like matter consisting of rarely substituted aromatic molecules with 4‒5 condensed rings. HGOCC extract was much less aromatic, the aromatic rings being highly substituted with fairly large alkyl substituents. The blended solvents yielded more extracts, and their molecular indexes were average between those obtained with each solvent separately. A remarkable finding was that the extracts obtained were characterized by significantly lower content of benzo(a) pyrene (BaP) compared to solvents used, its content further decreased as the time of coal dissolution increased.

Published: November 2022

In this paper, it was successfully established a novel and cheap water-proofing technique for protecting concrete from further damage caused by water leakage. This technique originated from the proper design and rational formulation of the materials including hydrophobic sand, silicon oil, tyre crumb rubber, and recycled motor oil. From this research, it can be seen that only one concrete showed hydrophobicity and all obtained concrete demonstrated significantly and in some cases extremely low water permeability relative to control concrete. To the best of current knowledge, this is the first paper, which studied the surface and water sorption properties of concrete modified by the addition of hydrophobic sand obtained by patented technology. The goniometer investigated the surface properties of the modified concrete. The results obtained including density, contact angle, change of weight, and maximum load capacity under high electro-hydraulic pressure were compared and discussed.

This work aims to obtain the dispersions based on polyethylene glycols (PEGs) of various molecular masses (MM) and perfluorodecalin (PFD) for subsequent direct fluorination. The solubility of the components was estimated using laser interferometry and differential scanning calorimetry, and it was shown that PEGs with different MM are not highly compatible with PFD. The dispersions were prepared during sonication. Gel permeation chromatography (GPC) analysis indicated that MMs almost did not change in this process. While the sonication of PEG-PFD, there is a formation of dispersion with the particle sizes distribution in a range of 0.4‒2 μm depending on the MM of PEG. The dispersion is metastable for several hours, even though its stability was significantly affected by additional bubbling with the gas flow. Moreover, the dispersions with a solid PEG phase (MM > 600 Da) were subjected to a smaller change compared to a liquid one (MM < 600 Da). The results of this research shed light on the applicability of the ultrasonic preparation of PEGs in PFD for liquid-phase fluorination with obtaining perfluorinated polyether of target MM.

The study deals with the transformation of decisions and division of labor within the family byprocessing the results of a qualitative, interviewed study of the target group of weekly workers.The study shows how decisions are restructured according to roles within the family and howthe roles of women and men change as a result of the regular absence of one family member.From the point of view of the approach to domestic work, the differences between weekdays andweekends, which can be considered as a consequence of weekend, come to the fore. In the courseof the analysis, we examined whether there was a change in the decision-making processeswithin the family as a result of the weekly (and if so, what areas were affected by the change)and whether there was a radical change in the division of family responsibilities as a result of theweekend. I present the results on the basis of two dimensions, on the one hand, of the phenomenaof disposition and decision-making over income, and, on the other hand, of the division of familyresponsibilities and problem-solving.

Introduction. Knowledge and the subjects whose activity results in increased knowledge play an important role in the modern economy, including information clusters. Theory. The “competitive region — competitive state” relationship is often considered in the design of clusters. Analysis. The information cluster, allowing for its specificity, should be macroeconomic, considered at the country level. Results. The structure of a competitive economy, developed by the author, allows one to consider macroeconomic clusters as a basis to ensure and improve the country’s competitiveness and to consider competitive business entities as a framework determining the competitiveness of the region and the country. In today’s Russian Federation, the formation of clusters goes quite active, with the support of governmental agencies; however, the number of clusters is not high enough, many spheres of activity and regions being clustered poorly. Conclusions. Russian information clusters should be formed to promote a knowledge economy and an increase of knowledge to design a framework for improving the competitiveness of businesses, regions, and the country in the whole.

Introduction. Regional university can be considered one of the key elements for building a regional economic development strategy. This article is devoted to regional university’s long-term development in modern environment. Theoretical analysis. In the context of «triple helix model» the network nature of the interaction between the participants of the innovative process is especially important. Today Russian universities are facing such challenges as urgent need of high-qualified graduates, investments, improvement of educational methods, creation and rapid development of university’s infrastructure, changes in ethic standards etc. Empirical analysis. Cooperation between business, government and universities is a burning issue. This is determined by drastic changes in the employers’ demands of graduates’ abilities, lack of universities’ public funding and the call for new off-budget financial sources. Results. Regional universities are supposed to take a proactive position in regional economy and to become the leaders of future innovations. The forthcoming changes should improve and reorganize the present system of regional higher education. The presumptive features of the new system should be the following: profound cooperation between university management, business and government, meritocratic approach, application of innovative educational techniques and teaching methods. This is to become the foundation of the highly efficient functioning of the universities and regional innovative development on the whole.
About the Management of the Pension Accumulation Taking into the Risk’s Control
Authors:   Saratov State University, Vigodchikova I. Y.
Published: November 2022

Introduction. To stably receive a high enough retirement in the future, the individual should early start to make pension savings and efficiently and deliberately be engaged in pension schemes not only to return but also to increase his/her savings. For this, pension savings schemes should be analyzed from the viewpoint of personal preferences and effective interest rates, and the risks of possible losses due to the activity of pension funds should be taken into account. The aim of this work is to develop recommendations for the individual to play an active role in the management of his/her pension savings and offer a mathematically-based model for making decisions on the structure of savings. To achieve this object, a version of pension savings is considered on the basis of preliminary analysis of pension funds’ performance indicators and making decisions on entering pension schemes by comparison of the investment risk (due to instable financial indicators) and the effective interest rate of the pension scheme selected. Methods. A number of new mathematical models of pension schemes and a new method of pension savings optimization on the basis of the uniform distribution of the risk of investment are proposed. Results. A model example of pension savings is provided with the account of the equitable distribution of the investment risk in three funds. Conclusion. To reduce risks, the participant himself can manage his/ her savings portfolio, entering several pension funds simultaneously and taking into account his/her assessments of profitability and risks. For this, it is desirable to develop an investment risk estimation system. It is advisable to take an appropriate effective interest rate as the profitableness of a pension scheme. The work presents a mathematical model for the management structure of pension savings and demonstrates its application. The obtained solution on the structure of savings can remain unchanged for a number of years, and may vary by reviewing main parameters and indicators of the risk of pension schemes.

Nos últimos anos, a temática das interações harmônicas e inter-harmônicas, no âmbito de sistemas renováveis de geração, vem ganhando destaque a partir de considerações acerca da sua dinâmica de controle e chaveamento de conversores. Neste contexto, cresce-se a necessidade de análise da ocorrência de oscilações harmônicas, as quais podem variar desde baixas frequências a elevadas. Assim, modelos computacionais têm sido testados e colocados à prova, com o intuito de avaliar sua representatividade frente aos fenômenos desta natureza. O presente informe técnico tem por objetivo esclarecer de forma simples e direta as diferenças conceituais dos fenômenos de emissão harmônica, além de propor uma revisão bibliográfica detalhada dos principais métodos de modelagem de sistemas eólicos, com foco em estratégias no domínio do tempo. Para tanto, três distintos modelos de aerogeradores serão implementados no simulador Atpdraw. Os parâmetros e medições utilizados como base de comparação dos modelos implementados são reais e advindos de um parque eólicos situado no nordeste do Brasil. De posse dos resultados do estudo proposto é possível concluir que os modelos apresentados podem ser utilizados como ferramentas importantes para análise dos fenômenos de interações harmônicas, e se mostram mais atraentes que os equivalentes de Thévenin e Norton para a representatividade da rede equivalente. Neste parque tem se verificado problemas correlatos à queima de equipamentos e mal funcionamentos provocados por interações harmônicas.

It was found that the concentration of profibrogenic biomarkers circulating in the blood of patients with MS(+)/AF(+)/OSA(+) is higher than in patients with MS(+)/AF(-)/OSA(+): galectin-3 (13,4 (8,5-17,6) and 8,4 (5,1-11,6) pg/ml, p < 0,0001), growth differentiation factor-15 (GDF-15) (1648,3 (775,32568,1) and 856,0 (622,5-1956,4) pg/ml, p < 0,0001), N-terminal peptide of type III procollagen (PIIINP) (95,6 (78,6-120,4) and 50,6 (38,9-68,3) ng/ml, p < 0,0001), N-terminal peptide of type I procollagen (PINP) (3459,4 (2167,1-4112,1) and 2355,3 (1925,0-3382,1) pg/ml, p < 0,0001). In the examined cohort of patients with OSA, positive correlations were found between galectin-3 and cardiotrophin-1 (r = 0,410, p = 0,00002), galectin-3 and GDF-15 (r = 0,430, p = 0,0003), galectin-3 and PIIINP (r = 0,451, p = 0,0001). Correlation analysis showed a strong positive relationship between the apnea/hypopnea index (AHI) and blood concentrations of GDF-15 (r = 0,661, p < 0,00001), galectin-3 (r = 0,519, p < 0,00001), interleukin 6 (r = 0,310, p = 0,0001) and C-reactive protein (CRP) (r = 0,361, p = 0,002). Negative correlations of the average level of SpO2 with CRP (r = -0,354, p = 0,001), galectin-3 (r = -0,451, p < 0,00001), GDF-15 (r = -0,637, p < 0,00001) were found. In patients with AF and OSA, fibrosis was more severe than in patients with AF without OSA (28,6 (23,6-36,6) and 13,5 (9,9-23,6) %, p = 0,0002). AHI positively correlated with the severity of fibrosis (r = 0,708, p < 0,00001). The patients with AF and OSA showed the strongest positive relationship between the severity of fibrosis and PINP (r = 0,572, p < 0,0001; в = 0,511, p < 0,0001) and galectin-3 (r = 0,449, p = 0,0009; в = 0,807, p < 0,0001). Conclusions. An increase in the concentration of fibrosis biomarkers in the blood is associated with an increase in the severity of left atrial myocardial fibrosis and probably has a pathogenetic role in increasing the risk of AF in patients with MS and OSA.
The Political Economy of South Africa’s Carbon Tax
Authors:   University of Sussex, Baker Lucy
Published: November 2022

The subject of carbon pricing is rising up the global policy agenda, as countries take action in the aftermath of the United Nations Framework Convention on Climate Change’s Conference of the Parties 26 summit in November 2021. South Africa is the only country in sub-Saharan Africa to have enacted a carbon tax to date, and, globally speaking, was ahead of the curve when it started to consider its implementation at the start of 2010. With a historically energy-intensive and carbon-intensive economy as a core feature of its minerals-energy complex, South Africa is the world’s 14th largest emitter of greenhouse gases, and the largest emitter on the continent. Its electricity grid is the world’s most carbon-intensive, and its primary energy consumption is ranked 17th globally. While the country’s gross domestic product is the 30th highest in the world, it is also one of the most unequal. It has a legacy of socioeconomic and political exclusion, and marginalisation created by the apartheid history that has persisted in the decades since the democratic transition in 1994. This paper asks to what extent and in what way has South Africa’s political economy shaped the process and implementation of its carbon tax? In answering this question, the report explores and analyses the design and implementation of the tax; the key criticisms to which it has been subjected; the effectiveness of the tax, not least in light of the considerable allowances and exemptions that have been included in its design; the relationship between the carbon tax and other existing climate change policies; and the potential relevance of South Africa’s experience for other countries on the continent.
Carbon isotopy of individual aromatic compounds of petroleum for their geochemistry understanding
Authors: Bushnev Dmitry
Published: November 2022

The article analyzes published and original data related to the carbon isotopic composition of individual aromatic compounds of fossil organic matter and oil. It has been shown that there is reliable evidence of the intramolecular isotopic heterogeneity of a number of molecules. For example the isotopically depleted carbon of the methyl group of alkylnaphthalenes and the terminal methyl of n-alkanes. The 13C inheritance from the biochemical precursor during the aromatization is also well documented in the example of diterpenes in the series abietic acid — dehydroabietane — simonellite — retene, as well as in the other terpene and steroid series. At the same time, there is evidence of carbon isotopic fractionation during the formation of several aromatic compounds from a single precursor. The increasing aromatization of the prebuild polycyclic structure does not change the 13C value of the molecule, and the formation of aromatic compounds with different numbers of aromatic rings in competing reactions leads to isotope differentiation in accordance with the thermodynamically determined distribution of carbon isotopes. If the suggestion is correct, it is the key to the understanding of specific petroleum aromatic hydrocarbons formation mechanism. It is possible that a comparison of 13C values for pairs of compounds formed during the transformation of one precursor will also provide information on the temperature conditions for the occurrence of the corresponding reactions.

La presencia de Odiseo en la Anábasis de Jenofonte
Authors: Olivares Chávez Carolina
Published: November 2022

El objetivo de este artículo es rastrear las alusiones homéricas existentes en la Anábasis de Jenofonte, para demostrar que gracias a esto construye un texto épico donde inmortaliza su gesta entre los persas y compara su actuación con la del gran Odiseo. Para lograr mi propósito también tomo en cuenta el Banquete, Memorables y la Apología, ya que en tales obras el autor menciona que los poemas de Homero formaban parte esencial de la cultura griega del siglo IV a. C. Entre mis fuentes principales se encuentran Homero, Christos Tsagalis, Emerson Cerdas. La originalidad de este artículo consiste en que, a diferencia de estudiosos como Naoko Yamagata, quien detecta solamente una alusión homérica en la Anábasis, sostengo que hay dos referencias directas y varias hechas de modo indirecto, pues, aunque no nombre a Odiseo, Jenofonte evoca situaciones parecidas a las que enfrentó el rey de Ítaca.
Autokontrola w postępowaniu sądowoadministracyjnym
Authors: Adamczyk Magdalena
Published: November 2022

Autokontrola dokonywana przez organ administracji publicznej czy sąd administracyjny jest instytucją, która umożliwia podjęcie stosownych czynności celem wyeliminowania z obrotu prawnego wadliwego rozstrzygnięcia. Instytucja ta, jako środek umożliwiający dokonanie kontroli legalności aktu przez podmiot wydający dane rozstrzygnięcie, budzić może wątpliwości na tle realizacji podstawowych zasad postępowania sądowoadministracyjnego, a także prawa strony do sądu. Analiza samokontroli w oparciu o przepisy prawa stanowionego, dorobek doktryny oraz orzecznictwo sądów administracyjnych przyczyni się do ustalenia charakteru tej instytucji oraz poczynienia wniosków co do zasadności i celowości jej wprowadzenia oraz stosowania w praktyce przez podmioty uprawnione.
Harmonizacja pełna uprawnień konsumenta w razie niezgodności towaru z umową w dyrektywie 2019/771 o sprzedaży towarów — część II
Authors: Kołodziej Anastazja
Published: November 2022

W tej części rozważań omówiono wpływ regulacji uprawnień konsumenta w dyrektywie 2019/771 na przyszłą zmianę poziomu ochrony konsumenta w polskich przepisach o rękojmi. W szczególności podkreślono, że wskazana jest kodeksowa implementacja tej dyrektywy. Uwagi dotyczą możliwych zmian w kodeksie cywilnym, w pierwszym rzędzie w zakresie kolejności wykonywania uprawnień przez konsumenta, co w porównaniu z regulacją art. 560 k.c. doprowadzi do osłabienia praw konsumenta co do wyboru jednego z czterech uprawnień z rękojmi. Następnie omówiono poszczególne uprawnienia konsumenta z rękojmi już występujące w k.c., z uwzględnieniem ich możliwych zamian przy transpozycji dyrektywy, a także obowiązek kupującego udostępnienia lub zwrotu rzeczy oraz uprawnienie konsumenta do wstrzymania się z zapłatą części ceny. Dodatkowo poruszono zagadnienia skutków przyczynienia się konsumenta do niezgodności rzeczy z umową oraz naprawienie szkody konsumenta wywołanej przez niezgodność towaru z umową.
Nowe rozwiązania w zakresie doręczania dokumentów sądowych i pozasądowych w postępowaniu cywilnym UE — rozporządzenie Parlamentu Europejskiego i Rady (UE) 2020/1784
Authors: Nekrošius Vytautas
Published: November 2022

Z dniem 1 lipca bieżącego roku weszła w życie trzecia wersja rozporządzenia dotyczącego doręczania dokumentów sądowych i pozasądowych (pierwsza wersja — rozporządzenie nr 1348/2000, druga — 1393/2007 i najnowsza — 2020/1784). Najnowsza wersja ma na celu rozwiązanie niektórych z najważniejszych problemów związanych z doręczaniem dokumentów sądowych i pozasądowych w państwach członkowskich Unii Europejskiej. Pierwszy problem dotyczy ustalenia miejsca zamieszkania adresata. W pierwotnej wersji rozporządzenia określono, że nie może ono mieć zastosowania w przypadku, gdy miejsce zamieszkania adresata jest nieznane. Znowelizowane rozporządzenie wprowadza po raz pierwszy system pomocy nadawcy w ustaleniu miejsca zamieszkania adresata. Powinno to znacznie rozszerzyć zakres stosowania rozporządzenia. Druga nowość dotyczy rozszerzenia stosowania technologii elektronicznych w komunikacji między jednostkami przekazującymi i przyjmującymi. System doręczeń ustanowiony rozporządzeniem staje się obowiązkowy, a państwa członkowskie tracą możliwość ograniczenia jego stosowania. Wreszcie w państwie członkowskim pojawia się nowy sposób doręczania dokumentów procesowych: doręczenie elektroniczne. W artykule omówiono te i kilka innych pomniejszych innowacji. Z analizy znowelizowanego rozporządzenia wynika, że wprowadzone poprawki powinny przyczynić się do usprawnienia procedury doręczania dokumentów w unijnym postępowaniu cywilnym oraz do znacznie aktywniejszego stosowania rozporządzenia w praktyce.
Szczególny przykład szkoły wyższej w nauce prawa administracyjnego — wybrane zagadnienia
Authors: Raszewska-Skałecka Renata
Published: November 2022

W szkole wyższej mają zastosowanie rozwiązania właściwe zarówno dla zakładu administracyjnego (w ramach ich działalności podstawowej — na przykład podczas zajęć, zaliczeń i egzaminów — występuje stosunek zależności zakładowej), jak i dla korporacji (na poziomie ogólnouczelnianym — „pracownicy uczelni, doktoranci i studenci stanowią wspólnotę uczelni”, ale i w zakresie dotyczącym studentów i doktorantów — „studenci w uczelni tworzą samorząd studencki” czy „doktoranci w podmiocie prowadzącym szkołę doktorską tworzą samorząd doktorantów”). Połączone tu zależności konstrukcyjne szkoły wyższej wzmacnia również decentralizacja autonomiczna (oprócz decentralizacji zakładowej i samorządowej) — tak w wymiarze wolności akademickiej, jak również autonomii administracyjnej.
The issue of similar handwritings with a particular focus on the determinants affecting the quality of producing a handwritten record
Authors: Skubisz-Ślusarczyk Sylwia
Published: November 2022

There are cases in the opinion-making practice where manuscripts produced by different persons demonstrate far-reaching similarities of graphisms. This may lead to a manifest error by an expert. Omitting the phenomenon of graphism similarity, which stems from the repetitiveness of analogous structural solutions in handwriting produced by different writers, may result in judicial errors. The objective of this paper is to present the problem of manuscripts showing far-reaching convergences regarding the handwriting features.
