The verbalization of the concept faith in the religious discourse by Josyf Slipyj
Authors: Mostova S. M.
Published: October 2021

Nowadays, in linguistics, the interest in the field of religion and communication within it has increased and the study of the religious discourse is becoming very popular. It contributes to the understanding of the religious picture of the world and the concept as a representative of the values, ideas, feelings, and associations.

The article is based on the testament, sermons and speeches by Josyf Slipyj who was a Major Archbishop and a Cardinal of the Ukrainian Greek Catholic Church. Previously he, as a public figure was banned and the issue of religious mentality was on the periphery, in particular, due to ideological considerations.

Josyf Slipyj always tried to organize a church space in Ukraine, which remains relevant today, because of the events and the religious context in our country. However, the issue of the discursive and linguo-conceptual analysis of the concept FAITH is unresolved. It is shown that this concept belongs to the deep foundation, one of the most important personal values. The purpose of the research is to study the verbalization of the concept FAITH in the religious discourse by Josyf Slipyj, which is the basis for the krainian linguistic picture of the world, universal category, the foundation of national consciousness, and at the same time the unique concept.

Realization of the set purpose provides solving necessary tasks: to trace the worldview of Josyf Slipyj and determine the place of the concept FAITH. The concept FAITH is considered from two aspects that are equally necessary for Christianity: understanding faith, which is trust and faith in someone or something through the recognition of truth and value (faith in the Holy Trinity, in the church). The religious heritage of Josyf Slipyj represents two mentioned aspects: Patriarch trusts and believes in Jesus Christ, eternal God, God’s will, God’s providence, God’s help, Liturgy, Church, unity, Ukraine, power of prayer, love, science, holidays.

So, in conceptual terms, the concept of religious discourse often includes different aspects of constants that affirm the Patriarch`s faith and transmit the essence of universal and national values, including ethical and religious categories.
Key Insights into What Makes Public Organizations Learn from Training Programs
Authors: Reichborn-Kjennerud Kristin
Published: October 2021

Public organizations often operate in rigid environments with standardized procedures that are not conducive to learning, yet it is crucial that they continuously improve at solving their societal tasks in a satisfactory way. There is a lack of knowledge about what factors are important for learning to occur in public organizations. Based on a questionnaire, this study looks at how different factors condition the way in which employees perceive standardized training programs in public organizations. The study demonstrates how a training program was perceived by two different professional groups, one being more accustomed to and accepting of standardized procedures than the other. The results show that the child welfare services had a more positive attitude toward the program than did the family counseling services. Employees working in an environment that is positive to employee feedback also perceived the program as more relevant, important and useful. Employees working in an environment that prioritized competence development perceived the program to be better organized and implemented and to be relevant to their work tasks. The article argues that these factors contribute positively to organizational learning and stresses the importance for leaders to develop an environment that is positive to employee feedback.
Induction of apoptosis through the up-regulation of endoplasmic reticulum stress sensors by 5-hydroxy-7- (4”-hydroxy-3”-methoxyphenyl)-1-phenyl-3-heptanone
Authors: Kwon Kisang , Kyung-Hee Kang , Kim Seung-Whan , Kwon O-Yu
Published: October 2021

The diarylheptanoid, 5-hydroxy-7-(4”-hydroxy-3”-metho-xyphenyl)-1-phenyl-3-heptanone (HPH), is isolated from rhizomes of Alpinia officinarum. There is no reported biological function for this compound other than the inhibition of pancreatic lipase. Cell viability, the expression of endoplasmic reticulum (ER) stress genes, the activation of ER stress sensors, and the induction of apoptosis and autophagy were confirmed following HPH treatment of PC12 cells. No cytotoxicity was observed when the cells were treated with 50 μg/ml HPH, but 40% cell death was observed using MTT assays with 100 μg/ml HPH. Although HPH did not change the expression of the ER chaperones PDI, binding BiP, and calnexin, it upregulated the expression of genes for the ER stress sensors ATF6, eIF2α, and PERK. HPH also induced apoptosis via the activation of ATF6 fragmentation, the phosphorylation of eIF2α, and XBP1 mRNA splicing. Eventually, the results of this study demonstrated that HPH induces apoptosis through upregulation of gene expression of ER stress sensors, which may provide a basis for the development of new drugs using HPH.

Authors: Lefaan Yosef , Mollet Julius Ary , Innah Herbert
Published: October 2021

The National Development Planning Agency of Indonesia has adopted the concept of development based on customary territories in Papua in the 2015-2019 National Midterm Development Plan (RPJMN). This RPJMN aimed to accommodate the mandate of the Special Autonomy Law Number 21 of 2001 regarding Special Autonomy for Papua Province. However, the RPJMN used a top-down development approach that accommodates more national and international interests than local and customary territories' interests. The main objective of this paper is to propose a new concept of sustainable development that uses a bottom-up development approach to reconcile both interests above. The concept is supplemented with the road map and simulation to explore the progress of sustainable development. The modeling and simulation of sustainable development progress consist of the human development index (HDI), human development indicators, and electricity demand using the system dynamics model. In 2050, the lowest HDI is 63.87 in Mappi Regency. Life expectancy is 68.53 years; the schooling expecting years is 12.19 years; the schooling mean years is 6.60 years, and the expenditure per capita is Rp7,599,010, - In 2050, the highest HDI is 94.83 in Sorong Municipality. Life expectancy is 80.73 years; the schooling expecting years is 18.00 years; the schooling mean years is 15.00 years, and the expenditure per capita is Rp19,869,057 – In 2050, the electricity demand in Mappi Regency is 46,032 MWh. Meanwhile, the electricity demand in Sorong Municipality is 1,137,746 MWh.

Published: October 2021

Objectives: Nowadays, vitamin D3 (VitD3) deficiency is among the most common dietary deficiencies around the world. Researchers have paid more attention to VitD3 because it is a vital element of the body and has a plausible relationship with various diseases such as diabetes mellitus type II. This study was conducted to examine the prevalence of vitamin D3 deficiency and its relationship with blood sugar levels in people with diabetes undergoing coronary artery bypass grafting (CABG).
Methods: An observational study was conducted in 2017 in Shahid Madani Hospital, Tabriz, Iran, for 8 months. Due to the use of census sampling, only 115 patients with diabetes and open-heart surgery were enrolled in the study. A questionnaire collected information on the participants' demographics, medical history, VitD3 levels and blood glucose levels. Data were analyzed using SPSS ver. 25.  Independent t-test was used to compare quantitative data, and chi-square test was used to compare categorical variables.
Results:  One hundred and fifteen out of 348 patients who had CABG surgery were diabetic. Moreover, 24.7% of patients with diabetes had VitD3 deficiency. The results of the coefficient-correlation test indicated that there was a significant relationship between the mean blood glucose level and VitD3 level (p  < 0.05).
Conclusions: The results of this study suggest that patients with diabetes can improve their blood glucose control after CABG surgery by taking sufficient VitD3. Therefore, it should be considered as a principle of the hospital operation to prescribe VitD3 prior to surgery for these patients.
Analysis of The Relationship Between GDP Growth and Foreign Direct Investment in Underdeveloped Countries: Tar Model
Authors: ÖZTÜRK Serdar , ATAMER Mert
Published: October 2021

Economists argue that a relation between foreign direct investments (FDI) and economic growth exists. In many studies, it has been investigated the way FDI affect economic growth. In the literature, it has been concluded that foreign direct investment has a positive impact on economic growth. In some studies, it was determined that there was no causality between economic growth and direct foreign investments. This article differs from the other studies in terms of both its perspective and results. In this article, it is important to analyze how the per capita GDP growth affects FDI in opposition to the studies in the literature and it is thought that this study will contribute to the literature. Another feature that distinguishes this article from others is that the analyses are not linear analysis but nonlinear analysis. Obtained results will guide policy-makers. The results are of great importance for policymakers in underdeveloped countries in terms of saying that they need to keep their GDP per capita above the determined threshold otherwise FDI entering their countries would decrease.

The restrictive function of legal responsibility and the limits of its action through the prism of proportionality principle
Authors: Kushnir Irina V.
Published: October 2021

We draw attention to the problem of excessive restriction risk of human and civil rights and freedoms in the process of establishing and applying the institution of legal responsibility by the state. We consider general theoretical issues of the concept and functions of legal responsibility. We substantiate the position on the need to separate the restrictive function from legal liability. As an intersectoral institution of Russian legislation, legal re-sponsibility is characterized by the performance of the following functions: restrictive, preventive, guaranteeing, restorative and educational. We draw attention to the issues of legal liability proportionality in relation to its restric-tive function. We disclose the content of proportionality principle in relation to legal responsibility as an intersectoral institution of legislation. We imagine that the remedy actively used in the legal policy of the state in the form of legal punishment and legal responsibility in general should correspond to the maximum extent to proportionality principle in order to prevent arbitrary and excessive restriction of rights and freedoms. Various kinds of deviations, deviations from the principle of proportionality of legal responsibility are supposed to be interpreted in theory as one of the most important prerequisites for the formation of dysfunction and imbalance of the institution in question. Violation of proportionality principle of responsibility in law is proposed to be interpreted as its dysfunction.
Reasons to escape from a place of detention by convicts with the right of movement without convoy
Authors: Cheremin Nikita V.
Published: October 2021

Dedicated to a topical topic for the penitentiary system of the Russian Federation (hereinafter referred to as the PS of the Russian Federation) – increasing the level of security, which is considered in the framework of a criminological analysis of the reasons for escaping from places of detention by a particularly considered category of convicts who are granted the right to travel without an convoy or escort. The commission of such a crime as es-cape not only disorganizes the activities of institutions executing punishment in the form of imprisonment, but also endangers public safety. The actions of the penitentiary system to organize a special operation to search for and arrest escaped criminals requires large material and physical costs. All this speaks of the relevance of the study, which can help in organizing preventive measures to prevent escapes. The purpose of the study was achieved by analyzing the criminal and penal legislation of the Russian Federation, analyzing official statistics, questioning and interviewing the heads of correctional institutions of the PS of the Russian Federation, as well as the special contingent; analysis of some decisions in criminal cases related to Article 313 of the Criminal Code of the Russian Federation for the period 2010–2020. As a result of the study, the characteristic reasons (objective and subjective) of the escapes of the investigated group of convicts were revealed, features are identified, which will allow in the future to organize preventive measures aimed at preventing and preventing escapes among convicts, who were allowed by the administration of the institution to have the right to leave the correctional institutions in order to economic service.

Authors: Izmalkov Alexandr V. , Kuznetsov Alexander A. , Kuznetsov Pavel A. , Kuzmenko Ella Y.
Published: October 2021

We analyze the law enforcement practice of judicial authorities on taxes and fees, since the Tax Code of the Russian Federation is a rather controversial regulatory legal act. Tax disputes arise both at the initiative of tax authorities and at the initiative of taxpayers. Purpose: to determine the main directions of law enforcement practice of courts in tax disputes. We use general scientific and specially legal methods as research methods. The focus is on the method of analysis. In the course of the research, we analyze the con-sideration of cases by judicial authorities on tax disputes, their quantitative and qualitative characteristics. We conclude that the emergence of disagree-ments between taxpayers and the state body when resolving the issue of the legality of their actions (inaction), as well as the legality of a non-normative legal act is the main reason for the formation of law enforcement practice in tax disputes. During the passage of all stages of the application of the law, it is also necessary to establish the existence of a cause-and-effect relationship between the actions of the taxpayer and the resulting consequences. The main points of this process go through several stages. We define the main directions of the law enforcement practice of courts in tax disputes.

Published: October 2021

This study examined the nexus between Exchange Rate and Non-Oil Export in Nigeria using time series data from 1985 to 2018. Secondary data were sourced from the Central Bank of Nigeria (CBN), National Bureau of Statistics (NBS) and World Bank Development Indicators (WDI). The study adopted Autoregressive Distributed Lag (ARDL) model and it was fitted with Seven variables; namely, Non-oil Export (NOE), Exchange Rate (EXR), Credit to Private Sector (CPS), Trade Openness (OPN), Inflation (INF), Interest Rate (INT) and Foreign Direct Investment (FDI). The results showed that the exchange rate has a positive and significant impact on non-oil export in Nigeria. Therefore, the study recommended that the Government should encourage international trade to boost non-oil export and increase foreign exchange earnings. Also, there is a need for the government to improve the financial institutions to make investment funds available. Lastly, there is a need to revisit the export-oriented policy to ensure that the non-oil sector is well catered for.

Modeling of cutting forces while boring heat – resistant alloy Inconel 718
Authors: Shykhalieiev Maksym , Medvedev Vadim
Published: October 2021

In this work, authors had made computer FEM (finite element method) simulation of machining holes in part made of heat-resistant alloy Inconel 718. For this simulation nonlinear solver LS – Dyna had been used. Material type for physical modeling of workpiece have been selected to Johnson – Cook formulation. Tool configuration is rigid and have dynamic stiffness in three dimensions in the fastening points. Graphs of cutting forces and moments of cutting for three different depths of cut had been obtained. In the beginning of the cutting, in addition to the smooth increase of cutting forces, high – frequency oscillations with amplitudes of 1 – 3 N also take parts. The resulting cutting force has pronounced harmonic oscillations at low frequencies. The maximum burst of amplitude occurs in the period from 0.9 to 1.3 seconds from the start of cutting. It is recommended to carry out a smooth increase of cutting forces at this time through cutting modes. High – frequency oscillations, which were insignificant in the context of each component of the cutting forces, due to the summation and oscillations of the holder play a crucial role in the oscillations of the boring moment.

Published: October 2021

Большой прогресс в технологии производства микроэлектронных устройств с экспоненциальным ростом сложности и быстродействия необходим для обеспечения непрерывного развития новых технологий, структур, устройств, схем и систем. В статье предложена новая модель переходных процессов p-МОП-структуры, предназначенная для современных микроэлектронных устройств, которые обеспечивают быструю динамическую реакцию. Предлагаемая модель обеспечивает получение зависимостей переходных нагрузочных токов как полиномиальных функций нормализованных плотностей канального заряда на границах канала с помощью модифицированной версии метода коллокации с кубическими сплайнами в симметричном телескопическом виде. Кроме того, исследовано оптимальное количество сегментов, которое необходимо для новой версии алгоритма коллокации с кубическими сплайнами. Также моделируется нормализованная плотность заряда канала в точках коллокации с помощью ее значений на границах канала, при использовании квазистатического подхода. Путем введения обратной функции для нормализованного канального напряжения перегрузки, переходные нагрузочные токи представлены в виде функции напряжений на выводах МОП-структуры. По сравнению с обычным методом коллокации кубическими сплайнами, новая модель имеет более высокую точность применительно к ЭКВ модели. Разработанная модель использована для стандартной 0,15 мкм технологии и проверена с помощью MATLAB R2014a. Полученные результаты показали, что модель обеспечивает высокую относительную точность (в среднем 99%) для всего времени, и абсолютную ошибку менее 5% от максимального значения в худшем случае.

Рассмотрена реконструкция томограмм в магнитно-резонансной томографии для различных степеней нестабильности поперечного градиента магнитного поля. Предложен метод минимизации влияния отклонения полученных точек измерений сигнала от регулярных положений на качество реконструированных томограмм. При обработке реальных томографических изображений определены предельные значения параметров нестабильности градиентов поля с учетом возможности их компенсации. Для оценки влияния нестабильности на точность конечных результатов проведена серия многократных процедур формирования сигналов в условиях разного разброса составляющих магнитного поля и последующей реконструкции. Показано, что построение и совместный анализ нескольких томографических распределений для разных углов ориентации системы магнитных градиентов поперечного фазо-частотного кодирования сигнала отклика улучшает структуру диагностических данных. При решении обратной задачи восстановления спиновых распределений получена компенсация искажений вследствие нерегулярности сетки формирования данных путем объединения массива измерений, проведенных при разных условиях. Проведена оценка качественных параметров реконструкции двумерных томографических распределений высокого разрешения в случае измерений сигнала отклика для двух и трех ориентаций его поперечного кодирования.
A Primer on Harnessing Non-enzymatic Posttranslational Modifications for Drug Design
Authors: Long Marcus , Ly Phillippe , Aye Yimon
Published: October 2021

Of the manifold concepts in drug discovery and design, covalent drugs have re-emerged as one of the most promising over the past 20-or so years. All such drugs harness the ability of a covalent bond to drive an interaction between a target biomolecule, typically a protein, and a small molecule. Formation of a covalent bond necessarily prolongs target engagement, opening avenues to targeting shallower binding sites, protein complexes, and other difficult to drug manifolds, amongst other virtues. This opinion piece discusses frameworks around which to develop covalent drugs. Our argument, based on results from our research program on natural electrophile signaling, is that targeting specific residues innately involved in native signaling programs are ideally poised to be targeted by covalent drugs. We outline ways to identify electrophile-sensing residues, and discuss how studying ramifications of innate signaling by endogenous molecules can provide a means to predict drug mechanism and function and assess on- versus off-target behaviors.
Can WiMAX IEEE802 Be Used to Resolve Last-Mile Connectivity Issues in Botswana?
Authors: Mokeresete Malebogo , Esiefarienrhe Bukohwo Michael
Published: October 2021

Amongst the advantages of using Worldwide Interoperability Microwave Access (WiMAX) technology at the last-mile level as access technology include an extensive range of 50 km Line of Sight (LOS), 5 to 15 km Non-Line of Sight and few infrastructure installations compared to other wireless broadband access technologies. Despite positive investments in ICT fibre infrastructure by developing countries, including Botswana, servicing end-users is subjected to high prices and service disparities. The alternative, the Wi-Fi hotspot initiative by the Botswana government, falls short as a solution for last-mile connectivity and access. This study used OPNET simulation Modeller 14,5 to investigate whether Botswana’s national broadband project could adopt WiMAX IEEE 802.16e as an access technology. Therefore, using the simulation method, this paper evaluates the WiMAX IEEE 802.16e/m over three subscriber locations in Botswana. The results obtained indicate that the deployment of the WiMAX IEEE 802.16e standard can solve most of the deployment issues and access at the last-mile level. Although the findings suggest that WiMAX IEEE 802.16e is more suitable for high-density areas, it could also solve rural areas’ infrastructure development challenges and provide the required high-speed connectivity access. However, unlike the Wi-Fi initiative, which requires more infrastructure deployment and less on institutional and regulatory frameworks, the deployment of WiMAX IEEE802.16e requires institutional and regulatory standards.
Implications of Climate Change on Soil Functions: A Case for Achieving Local Coconut Sufficiency from Sustainable Agricultural Practices
Authors: Egbunike Chinedu , Okoye Nonso , Okechukwu Okoroji-Nma
Published: October 2021

Climate change is a major threat to agricultural food production globally and locally. It poses both direct and indirect effects on soil functions. Thus, agricultural management practices has evolved to adaptation strategies in order to mitigate the risks and threats from climate change. The study concludes with a recommendation the coconut farmers should explore the idea of soil biodiversity in a bid to mitigate the potential negative impact of climate related risk on the farming. The study proffers the need for adopting sustainable agricultural practices to boost local coconut production. This can contribute to the simultaneous realisation of two of the Sustainable Development Goals (SDGs) of the United Nations: SDG 2 on food security and sustainable agriculture and SDG 13 on action to combat climate change and its impacts. The study findings has implications for tackling climate change in Sub-Saharan Africa and in particular Nigeria in order to boost local agricultural production and coconut in particular without negative environmental consequences and an ability to cope with climate change related risks.
The Role of Energy Return for Energy Invested (EROEI) in Dissipative Autocatalytic Systems
Authors: Bardi Ugo , Lavacchi Alessandro , Perissi Ilaria
Published: October 2021

The Energy Return on Energy Invested, EROEI, is known as an important parameter for evaluating the efficiency of energy-producing technologies. In this paper we examine the concept of EROEI from a general viewpoint, giving insights on a wider range of applications. In general, natural resources can be seen as energy stocks characterized by a “potential” that can be exploited by creating intermediate stocks. This transformation is typical of dissipative systems and for the first time we found that Lotka-Volterra model, usually confined to the study of biology of populations, can represent a powerful tool to estimate EROEI for some such systems, providing an understanding of the reason for the overexploitation phenomenon and, in some cases, the collapse of the exploiting system.

A Phase-Field Based Approach for Modeling the Cementation and Shear Slip of Fracture Networks
Authors: Jammoul Mohamad , Wheeler Mary
Published: October 2021

Modeling the geomechanical deformations of fracture networks has become an integral part of designing enhanced geothermal systems and recovery mechanisms for unconventional reservoirs. Stress changes in the reservoir can cause large variations in the apertures of fractures resulting in drastic changes in their transmissivities. At the same time, sustained high injection pressures can induce shear slipping along existing fractures and faults and trigger seismic activity.

In this work, a novel approach is introduced for the simulation of cementation and shear slip of fractures on very general semi-structured grids. Natural fracture networks are represented in large scale reservoirs using the phase-field approach. The fluid flow through fractures is simulated on spatially non-conforming grids using the enhanced velocity mixed finite element method. The geomechanics equations are discretized using the continuous Galerkin finite element method. The single-phase flow and mechanics equations are decoupled using the fixed stress iterative scheme. The model can predict shear slipping and opening/closure of fractures due to induced stresses and poromechanical effects.

Two synthetic examples are presented to model the effects of injection/production processes on the cementation and shear slip of fractures. The impact of the fractures' orientation and their connectivity on the hydromechanical response of the reservoir is also considered. The examples illustrate the strong impact of the dynamic behavior of fractures and the accompanying poroelastic deformations on the safety and productivity of subsurface projects.
Acute PEBI Grid Generation for Reservoir Geometries
Authors: Manzooor Shahid , Edwards Michael G. , Dogru Ali H.
Published: October 2021

An unstructured grid generation method is presented that automates control-volume boundary alignment to geological objects and control point alignment to complex wells. The grid generation method is coupled with an iterative acute mesh reconstruction technique, to construct essentially acute triangulations, while satisfying quite general geometric constraints. For well aligned grids control points are constrained to the well trajectory and protection circles are used, whereas for boundary aligned grids halo construction is performed. Unstructured Delaunay triangulations (DT) have the desirable locally orthogonal perpendicular bisectional (PEBI) property, required by the industry standard two-point flux approximation for consistency for isotropic fields. The PEBI property can only be exploited if such grids are comprised of acute simplexes, with circumcentres located inside their respective elements. The method presented enables acute DT layered mesh generation while honoring internal boundaries and wells in a two dimensional space. A dual (Voronoi) grid derived from a feature honored simplicial mesh is then projected in the vertical direction generating 2.5D PEBI grids. Effectiveness of the method to construct acute PEBI grids honoring geological objects and complex wells is demonstrated by meshing representative reservoir geometries. Numerical results are presented that verify consistency of the two-point flux on the resulting boundary-aligned acute PEBI grids. Development of an unstructured grid generation method which 1) Automates interior boundary alignment, 2) Honors features with respect to control point and/or control volume, and 3) Generates acute PEBI grids for reservoir geometries is presented. A unique workflow is presented to generate boundary aligned acute PEBI grids for complex geometries. Development of boundary aligned grids that honor both geological objects and multilateral complex wells, together with mesh reconstruction to ensure circumcenter containment is presented. Further, 3D PEBI grid generation method which can limit refinement to well perforations and geological objects is also described.
