Authors: Daniluk Katarzyna 
Published: May 2022

Abstract

Subject and purpose of work: This study investigates the effectiveness of equity investment in renewable energy companies. The aim of the research is to compare the effectiveness of investing in the stocks of companies from the conventional and renewable energy sector on the Warsaw Stock Exchange.

Materials and methods: The research material consisted of the stock prices of selected energy companies listed on the Warsaw Stock Exchange’s Main Market and NewConnect. Representative investment portfolios were created and their average monthly logarithmic rates of return, standard deviations and Sharpe ratios for the period 2013–2020 were examined.

Results: The portfolios of renewable energy companies were characterised by higher risk, but also higher average returns; as a result, they achieved higher risk-adjusted efficiency ratios than the portfolios of conventional energy companies.

Conclusions: Shares in renewable energy companies, despite a significant risk, can be an attractive form of investment, which is crucial for privately financing the energy transformation in Poland.
Russian internal migration in Kuban’. The case of Krasnodar.
Authors: Mamayusupova Kristina 
Published: May 2022

Abstract
Environmental migration owes its existence to pull factors, i.e. disastrous environmental factors that push people to migrate to other lands. In this article the definition of environmental migration is reversed, since in Russian internal migration towards the Kuban’ region and, in particular, towards the city of Krasnodar, pull factors are transformed into push factors, giving rise to migration in which the climate is an attractive pole, around which other migratory causes are placed. The migratory flows directed towards the city of Krasnodar are a great resource of demographic rebirth, the motor of regional and city life, the growing stimulus towards rapid urban development and the transformative and generative force of infinite territorial images, endlessly created by each migrant present on the territory under examination.
An Automated Algorithm for the Sectional Analysis of Reinforced and Prestressed Concrete Columns
Authors: Kovacs B. , Toader T.-N. 
Published: May 2022

Abstract
This article aims to describe an automatic calculation algorithm developed for the analysis of reinforced concrete and / or prestressed concrete cross sections. The sectional analysis consists in the generation of two characteristic curves: the bending moment - curvature (M-1/r) and the axial force - bending moment (N-M), the calculation approach and the implementation of the algorithm being briefly described by the mathematical equations used. To verify the calculation algorithm, the results were compared with those obtained from experimental tests in the laboratory but also with numerical simulations using commercial computational software based on the finite element method (FEM). The algorithm was written in the MATLAB programming language. The results obtained with the developed algorithm show conservative results when compared to the experimental ones. Moreover, the bending moment resistance for prestressed concrete columns using bonded tendons is better estimated with at least 10% when compared with the one obtained with a fiber based cross section nonlinear analyses.

Published: May 2022

Abstract
An optimized compact-based method is introduced that verifies the distance measuring precision of surveying instruments. The paper describes the improvement of the compact based method not only in establishing a compact facility by using shorter lengths and folded path but also in the assessment process by implementing the official ISO standard for electronic distance measuring equipment (ISO 17123-4). The method produces statistically comparable results to ISO standards and is suited for regular instrument checks in institutions with limited space available.

Abstract
The aim of this study is to investigate the fresh and hardened properties of the self-compacting heavy-weight concrete (SCHWC) and to develop a mathematical model for the prediction of these properties. The binder was the Portland cement and fly ash (FA). Barite aggregate was used to achieve the heavy-weight concrete (HWC). A polycarboxylate based super plasticizer was used to increase workability and reach self-compacting feature. To research the fresh and hardened properties SCHWC many concrete mixes were prepared accordingly with “water-cement ratios”, “total aggregate-cement ratios”, and “fly ash-cement ratios”. These samples were tested to get the slump-flow, V-funnel, 7 and 28-day compressive strength values. The Response Surface Methodology (RSM) was used to develop regression equations using these experimental results. It is observed that the estimated values obtained with RSM are compatible with those obtained by the experimental method for the fresh and hardened properties of SCHWC.

Abstract
Water Supply Systems (WSS) can very well be dubbed as the backbone of every major human settlement for thousands of years at this point as every major human settlement throughout history has, regardless of time period or rural/urban erection or evolution has had its emplacement close to if not dead center over a significant water source that can provide this valuable and desperately needed resource to the populace. Of course, with the passage of time and the ever increasing number of the population and their life style, new techniques and technologies were incorporated within the grand design of the water supply pipeline, mainly automation and operation reliability boosts by means of electricity. It is a given that electrical current is not cheap to produce and maintain, although it is a field of ongoing study and research when it comes to optimizing the energy consumption of any system that runs on this costly resource, both for making the overall operation of the entire system more reliable but also more economical, all the while taking inspiration of multiple specialty works published within this field and, of course, already established local and European Union standards within Romania.

Abstract
The paper presents a case study for the evaluation and comparison of three calculation methods in terms of taking the water flows resulting from storms and after melting snow for a metropolitan area, whose rainwater catchment system is the most often completely over run, with frequent flooding in the area. The study compares the results of three calculation methods by correlating the relationships and values used in the literature with the real situation determined on several calculation sections, on different water courses in the proposed area. Based on comparisons for the obtained results, the paper presents a series of conclusions that could be useful in urban systems projects.
Inheritance Tax Evasion in Germany
Authors: Linseis Philippe 
Published: May 2022

Abstract
It is estimated, that between 2015 and 2024 about 3 trillion € will be inherited in Germany. Due to far-reaching tax exemptions, the inheritance tax revenue per year is only about 7 billion €. Despite the fact, that the income or value-added tax burden is significantly higher, the inheritance tax is more unpopular than other taxes. The objective of the paper is to figure out, whether there is evidence of high tax evasion in the field of German inheritance tax, with a view to the low tax revenue and the high unpopularity of the tax. Therefore, data from the official inheritance tax statistic is compared with secondary data from studies, which estimate the yearly wealth transfer to the next generation by using survey data. The assumption is, that asset classes, which are easy to evade, should be recorded with a lower amount in the official tax statistic, than in the survey-based estimations. But the results do not show evidence of high tax evasion in the field of inheritance tax. As until now, only a small part of the inheritances is recorded in the official inheritance tax statistic, for the future it is recommended to the government, to record all inheritances in the official statistic. Because of far-reaching reporting obligations, the tax offices anyway have knowledge of most inheritances and the additional bureaucratic effort to record the additional data in the official tax statistic is small.

Authors: Gagoshidze Tamar 
Published: May 2022

Abstract
This article aims to describe the origin and development of supervision in Georgia, especially in the sector of social workers whose services are focused on the needs of people in difficulty. We will also talk about how training programs and providers (supervisors) are organized today. The intervention of supervisors in social work is very recent in Georgia, but it is notable that it has already impacted in a positive way, which statistics are shown in the article. The information is important for practicing supervisors, those in training, as well as those considering training, and also for those who would simply like to know more about the subject. Currently, scientific and statistical publications on the supervision of social workers in Georgia are quite scarce. We are interested, from a comparative and international perspective, in how supervision is developing in Georgia and where it stands today. The following description presents, from an outside observation, the result of research, statistical data, and interviews carried out with social workers, as well as with the group of supervisors of The LEPL Agency for state Сare and assistance for the (statutory) victims of human trafficking of the Ministry of Internally Displaced Persons from the Occupied Territories, Labor, Health and Social Affairs of Georgia.
The Competency of Changing the Deed Legal Framing in Case of Case Declination By the Competent Body. Resumption and Repetition of the On-Site Investigation
Authors: Palcu Pavel , Moroșteș Anca Florina 
Published: May 2022

Abstract
The criminal cases solved lately by the Prosecutor’s office by the court and by the local prosecutor’s offices brought under discussion and caused various opinions on the competency of changing the legal framework of the deed by hitting or other violent acts to attempted murder provided the competency being declined by the prosecutor’s offices by the district courts to the prosecutor’s office by the county court. This issue has become particularly important in view of the recent finding by the Constitutional Court that the elimination from absolute nullities of non-compliance with the rules of substantive jurisdiction and according to the quality of the person of the criminal prosecution bodies is unconstitutional [1]. There are also different points of view regarding the resumption and repetition of the on-site investigation, the conditions in which they intervene, who continues to carry it out, but also the way in which their forensic fixation is fixed.
Society and Law During the SARS-CoV-2 Health Crisis – Legal Thinking Issues and Normative Syntheses
Authors: Roghină Răzvan Cosmin 
Published: May 2022

Abstract
In this paper, we aim to observe, from a bird’s eye view, the meaning for which law dictates behaviors molded on values naturally hierarchized. The right to life is the absolute value that maintains its central position in any axiological hierarchy. Of course, we refer to the typology of societies connected to democratic and liberal values (more or less accentuated). We propose an approach with philosophical accents while traveling through the sphere of international regulations that protect rights and freedoms. All these will be related to the SARS-CoV-2 pandemic context. We will pay attention to the Romanian political praxis and constitutional justice during the health crisis. Finally, we will explore some legal and social thinking landmarks about what it means to approach a health crisis when it comes to understand and value freedom within the human existence coordinated by law.
Theoretical and Practical Analysis on the Quality of Active Subject of the Corruption Offenses of the Bank Clerk in the Sense of His Assimilation to the Civil Servant
Authors: Moise Gheorghe 
Published: May 2022

AbstractThe quality of the active subject of the bribery offense that can be retained to the bank clerk is based on the logical-legal argument that the duties he performs are subject to the control of a public authority, which recognizes that at least in terms of the importance of this activity. type of official we place ourselves in an area of authority and public interest. If at the beginning the legislator placed the bank clerk among the private persons who in terms of activities were likely to acquire the status of active subject of the crime of bribery, then he returned and placed him among the category of employees assimilated to civil servants. This much stronger link between the activity of this official, the purpose of his duties and the subordination of his own activity to a public authority, was the new argument underlying the current criminal regulations, which recognizes the quality of active subject of the offense of bribing the bank clerk.
Adaptive stochastic management of the storage function for a large, open reservoir using learned fuzzy models
Authors: Kozel Tomas , Stary Milos 
Published: May 2022

Abstract
The design and evaluation of algorithms for adaptive stochastic control of the reservoir function of a water reservoir using an artificial intelligence method (learned fuzzy model) are described in this article. This procedure was tested on the Vranov reservoir (Czech Republic). Stochastic model results were compared with the results of deterministic management obtained using the method of classical optimisation (differential evolution). The models used for controlling of reservoir outflow used single quantile from flow duration curve values or combinations of quantile values from flow duration curve for determination of controlled outflow. Both methods were also tested on forecast data from real series (100% forecast). Finally, the results of the dispatcher graph, adaptive deterministic control and adaptive stochastic control were compared. Achieved results of adaptive stochastic management were better than results provided by dispatcher graph and provide inspiration for continuing research in the field.
Analytical and numerical investigation of mechanical energy balance and energy loss of three-dimensional steady turbulent flows in open-channels
Authors: Mahmoudi Mahsa , Banihashemi Mohammad Ali 
Published: May 2022

Abstract
Study about the mechanical energy balance and the energy loss of 3-D turbulent flows in open-channels has its own complexities. The governing equation of the mechanical energy in turbulent flows has been previously known and includes turbulence parameters that their calculations or measurements are not easy. In this study, a form of the total mechanical energy equation that leads to a number of significant physical insights is analytically investigated, from which analytical relationships for the energy loss estimation in 3-D turbulent flows are defined. The effect of different turbulence parameters is reflected on the new relationships and analyzed by equalizations replacing unknown correlations with closure approximations using the numerical turbulence simulation. In order to investigate the application of the analytical relationships, numerical simulations are performed by using OpenFOAM software to solve the Navier-Stokes equations with the RSM turbulence model in open-channels with different geometries. Then, the contribution of the turbulence parameters to the total mechanical energy balance is evaluated in uniform and nonuniform turbulent flows and their difference is analyzed, that leads to identify the parameters affecting the friction and local losses. The results demonstrate that the magnitudes of the turbulent diffusion, the work done by the viscous stresses pertaining to the mean motion and the viscous diffusion of the turbulence energy are substantially smaller than the other terms of the total energy equation for turbulent flows in open-channels with different geometries, while the effect of the variations of the turbulence kinetic energy and the work done by the turbulence stresses, that has not been considered in the previous mechanical energy equations, is more important in complex flows. From a practical viewpoint, in order to study the details of the total mechanical energy balance and the energy loss in 3-D turbulent flows with the presence of the secondary currents, the proposed method can be useful.

Published: May 2022

Abstract
The automotive industry is one of the fastest growing sectors and therefore places demand on many other sectors and increases the need for cooperation. With the development of the automotive industry, tires have become an integral part of society and the everyday life of the individual. As a result of the company’s development as a connection of transport, the demand for tires is increasing and the production of waste tires is also related to this. The use of end-of-life tires is almost endless and that is why tires are good to use in the circular economy. The circular economy is an economic system that aims to keep products and materials in use for longer, thus increasing their productivity and reducing waste. The paper presents a methodical concept of the plan for the extension of production capacities of rubber-based pressed products with the intention to produce noise reduction panels. The investment consists of the acquisition of the pressing machine and respective mould in the amount of € 180,000. Based on the selected assessment methods it can be stated that the NPV reaches + 69,360 €, Profitability index is 1.38, Internal Rate of Return is 23.8% and the payback period is estimated for 4 years and 4 months, at the considered production capacity of 14,000 m2/year.
Self-Knowledge, Who God Is, and a Cure for our Deepest Shame: A Few Reflections on Till We Have Faces
Authors: Baggett David , Baggett Marybeth 
Published: May 2022

Abstract

Till We Have Faces is a retelling of the Cupid/Psyche myth with a few twists, namely, a nonstandard narrator and the inability of Psyche’s sister, Orual, to see the palace. Both innovations lead the reader to understand better the dynamics at play in Orual’s effort to disrupt Psyche’s life with her husband/god. The inability to see, on Orual’s part, at first suggests that the nature of the story is primarily epistemological. What is it that can be reasonably known or inferred? Digging deeper, however, reveals that the epistemic elements are actually penultimate, and that instead the book bolsters an ethically robust epistemology. Who we are deeply affects what we can see. Before Orual could apprehend the nature of the gods, she had to be brutally honest about who she herself was. A victim of abuse who was constantly shamed for reasons beyond her control, she is a sympathetic character in several ways, but she gradually moves from being victim to victimizer, treating others as means to ends, and, in the case of Psyche, ‘loving’ her in a way that was more hate than love. Self-knowledge was needed for Orual to apprehend the truth. She comes to realize her treatment of Bardia, Batta, Redival, and especially Psyche was not as pure and altruistic as she had thought. She had to come to terms with the ugliness within herself, and her penchant for consuming others, before she could hope to see the beauty and love of the gods for what they were.
Insights of C. S. Lewis Concerning Faith, Doubt, Pride, Corrupted Love, and Dying to Oneself in Till We Have Faces
Authors: Breitenbach Zachary 
Published: May 2022

Abstract
In Till We Have Faces (TWHF), C. S. Lewis combines his passion for pagan mythology with his knack for communicating Christian truths via story, powerfully illustrating a number of theological and moral positions that are prominent in many of his other writings. This article examines two major themes in TWHF that are also emphasized heavily within Lewis’s prose: (1) maintaining faith (which is examined from various angles) in the face of various emotionally-driven temptations to doubt; and (2) recognizing that pride prevents us from knowing God and corrupts the love we have for others into a jealous hatred. The article uncovers a variety of ways that Lewis masterfully paints a picture via the characters and the story of TWHF that exemplifies religious and ethical insights within these two themes.
Reflecting Christ in Life and Art: The Divine Dance of Self-Giving in C. S. Lewis’s Till We Have Faces
Authors: Rials Megan Joy , Walls Jerry L. 
Published: May 2022

Abstract
This essay examines how C. S. Lewis, in Till We Have Faces, illustrates the Christian’s journey of sanctification through the pre-Christian story of his main character, Orual. She must gain two ‘faces’ in this process that correspond to the two books she writes. First, she must gain the face of self-knowledge through humility. The key components to this face are her memory and the act of writing of her first book, which together create a mirror to reflect her sin back to her. Second, Orual must gain the face of transformation through divine agape love. The humility she learned from her first face now allows her to enter what Lewis describes as the dance of self-giving, which is a crucial element to the second face of transformation in its mortification of Orual’s sin and selfishness. In the second face, Orual gains access to an ‘actual language’ that transcends merely verbal words and involves worshipping the god with her whole being, as do we in being transformed to reflect Christ more clearly. Orual’s writing is a form of this ‘actual language’, and her second book that shares her personal encounter with the god of the mountain reflects to others the beauty of the divine. Similarly, Christians should reflect Jesus with their lives and their art, which are inextricably intertwined because a life lived for Him is the highest form of artwork they can create.
Virtuality and Truth. On Literature in Merleau-Ponty’s Indirect Ontology
Authors: Pazienti Paola 
Published: May 2022

AbstractThis paper aims to investigate the importance of literature in Maurice Merleau-Ponty’s reflections concerning two strictly connected phenomenological themes: 1) the virtuality of objects and of existence itself; 2) the genesis of truth and the intuition of essences. According to Merleau-Ponty, modern novelists have adopted a phenomenological method: instead of ‘explaining’ the world through words, they ‘show’ the lifeworld and its paradoxes indirectly. In his view, and against Jean-Paul Sartre’s position, analyzing literature means developing a theory integrating perception and the imagination. Moreover, at the beginning of the 1950’s, this perspective led Merleau-Ponty to a deep revision of the Sartrian concepts of spontaneity and engagement in literary practice in favour of a theory of expression as style. As a conclusion, the paper argues for the key-role of literature in Merleau-Ponty’s indirect ontology as a way of rediscovering unity and harmony behind the metamorphosis of reality.
