Published: November 2020

In order to reduce the environmental burden of chemicals, various new alternatives to seed protection are being sought. Our aim was to find an environmentally acceptable solution leading to the inactivation of seed-borne phytopathogenic fungi Fusarium culmorum on the surface of wheat and barley seeds with a positive effect on their germination. As a low-temperature plasma (LTP) source, a Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used. Plasma generated by DCSBD is non-equilibrium, cold, diffuse, macroscopically homogeneous even in ambient air at atmospheric pressure. Experimental results showed that LTP treatment in the range of 120—300 s significantly inhibits the growth of F. culmorum on the surface of the seeds. The efficiency of LTP treatment was compared with traditional seed protection processes using chemical fungicide and also with combined seed pretreatment by plasma and subsequent application of chemical fungicide. No growth of F. culmorum was observed after the combination of Vitavax 2000 fungicide application in the dose of 10 % and 60 s of LTP treatment even on the 5th day of incubation. Better wettability of seeds with the chemical fungicide was related to the change on seed surface, which becomes hydrophilic after 10 s of LTP application. Short LTP exposure times did not affect germination and improved the growth parameter of cereal seeds. By combining physical (LTP) and chemical (Vitavax 2000) treatments of cereal seeds, it is possible to effectively reduce the required amount of chemical fungicide and to stimulate germination and early growth seed parameters.

Published: November 2020

The objective of the study was to investigate whether low-level 915 MHz GSM-modulated radiofrequency (RF) radiation impairs microtubular structure and affects normal cell growth. V79 cells were exposed to a GSM-modulated field in a Gigahertz Transversal Electromagnetic Mode cell (GTEM cell) for 1, 2, and 3 h. Signal generator combined with power and chip modulator generated the electromagnetic field (EMF). The electric field strength was adjusted to 10, 20, and 30 V/m, and the average specific absorption rate (SAR) was calculated to be 0.23, 0.8, and 1.6 W/kg. The structure of microtubule proteins was assessed by indirect immunocytochemistry, and cell growth was determined based on cell counts taken every day over six post-exposure days. Three-hour radiation exposure significantly altered microtubule structure regardless of the electric field strength. Moreover, on the third post-exposure day, three-hour radiation significantly reduced cell growth, regardless of field strength. The same was observed with two-hour exposure at 20 and 30 V/m. In conclusion, 915 MHz GSM-modulated RF radiation affects microtubular proteins in a time-dependent manner, which, in turn, affects cell proliferation. Our future research will focus on microtubule structure throughout the cell cycle and RF radiation effects on mitotic spindle.

Authors: Yankov G. , Ilieva V. , Vladimirov B. , Kovacheva M. , Mekov E. , Petkov R.
Published: November 2020

Gastroesophageal junction adenocarcinoma is a rare type of cancer of the esophagus. It is usually diagnosed in advanced stages and much less frequently in the earlier stage, where surgical treatment is essential. Surgical treatment is also essential in kidney cancer. The occurrence of synchronous malignancies with an esophageal malignancy is a well-described phenomenon with an incidence ranging from 3.6 to 27.1%. To the best of our knowledge, only 11 cases of synchronous esophageal and renal cell carcinoma (RCC) have been previously described. We present a patient operated simultaneously for cancer of the gastroesophageal junction with synchronous renal cell carcinoma. The finding in the kidney was accidentally discovered by the routine CT scan on the occasion of the relatively early carcinoma of the gastroesophageal junction detected by upper endoscopy. The patient was admitted to the Thoracic Surgery Department, where Ivor-Lewis gastroesophagoplasty and right nephrectomy simultaneously were performed. The patient was followed for 5 years without evidence of disease progression.

Published: November 2020

Gaucher disease (GD) is a multi-systemic disease with a low population frequency. It is a lysosomal storage disorder (LSD) that causes accumulation of glucocerebroside in the so called Gaucher cells predominantly in areas like the spleen, liver and bone marrow. Type I GD (GDI) is the most common form and usually does not involve the brain and the spinal cord. The symptoms can range from mild to severe and may appear anytime from childhood to adulthood. Diagnostics can often be challenging and imposes looking at person’s medical history, symptoms, physical exam, and laboratory test results. We present a difficult to diagnose case of a 34-year-old woman admitted to the Clinic of Hematology, “Sv. I. Rilski” hospital with splenomegaly, normal laboratory findings and non-enlarged liver. She didn’t show focal neurological symptoms. A series of tests were assigned including genetic targeted analysis. The case is an example of a rare genetic disease with mild clinical symptoms. Diagnosis of Gaucher disease, type I was confirmed by measurement of a GBA enzyme activity and identification of mutations in the GBA gene inherited in an autosomal recessive manner. Thanks to the efforts of the clinical team, the assignment of adequate clinical and laboratory tests and their correct interpretation, the patient was subjected to enzyme replacement therapy (ERT). Although the diagnosis was settled relatively late (at 34 years of age), the correct therapy slowed down the invalidation and improved the quality of life of the patient.

Published: November 2020

This study aims to assess the awareness and opinions of employees and children living in foster care homes about the Romanian Clean Air Legislation. The assessment was performed six months after the implementation of the antitobacco legislation (Romanian Law no.15/2016), in three Romanian counties (Alba, Mures, and Covasna) including 178 employees and 368 children from 59 foster care homes. Data were collected using an anonymous paper and pencil questionnaire. Descriptive statistics and chi-square test were used for data analysis (significant difference if p < 0.05). Almost one third of the employees and children were smokers from the forest care homes. Nearly, all the employees and most of the children were aware of the legislation, most of them have also noticed some kind of measures taken by foster care homes against smoking. As claimed by smokers, almost two-thirds of them smoked like they used to do before the legislation, more than a quarter stated that they decreased the number of daily smoked cigarettes and nearly a quarter intended to quit smoking in the future. A half year after the implementation of the legislation most of the employees and children living in foster care homes admitted that they knew about the change and it affected their smoking habits. Most of them have also observed some kind of measures taken against smoking. Despite these measures there were still smokers in the foster care homes, so there would be a need for more campaigns against smoking in the future.

Published: November 2020

In human trichinellosis, it is important to know the peculiarities of objective manifestations in order to associate the antiparasitic therapy to support the systems and organs affected by this disease. We considered 1112 cases of human trichinellosis recorded between 1983 and 2013 in Braşov County. Objective clinical examinations show that cardiovascular manifestations were most frequent (12.32%). Patients showed these characteristics in the following order: angina, palpitations, and shortness of breath. Digestive disorders were found in 11.27% of the patients. Nine percent of the patients presented respiratory clinical signs. Correlating the objective physical findings with the recorded forms of disease we observe that cardiovascular manifestations prevail in all moderate, moderately severe, severe even in the mild form of the disease. These are followed by digestive and respiratory manifestations that are recorded at high parameters in moderate, moderately severe and severe forms of the disease.

Published: November 2020

The aim of the study was to compare the classical animal model (based on total milk for 305 days) with the Test-Day model (using monthly records of milk yield from Official Records of Performances). The data set derived from a total 175 animals (cows with records, parents of these animals and the descendants) from two Romanian breeds (Romanian Black Spotted and Montbeliarde), the phenotypic and the pedigree information arisen from National Research Development Institute for Animal Biology and Nutrition (IBNA-Balotesti). The selection criteria to be included in the analysis for each cow was to have at least 3 test-days and the days in milk between 200 and 330 for the Test-Day model and the total amount of the 305- day lactation yield for classical Animal Model respectively. Both models use B.L.U.P methodology and for that reason all the estimates were adjusted for fixed effects and all the breeding values and the solution for fixed effects were estimated simultaneous. For the animal model the fixed effects used was the breed and the year of performing and for the Test-Day model was an extra one, the test day effect. The correlation calculated between test days was very high (over 90%) for consecutive tests, and was getting lower when the days between tests was higher (under 40%). Also, in terms of heritability the values were in normal limits throughout lactation, except at the beginning and end of lactation period where these values were a little bit higher. The comparison of the ranking of breeding values with Spearman rank correlation shows that in 80% of the cases the ranking was similar for both models. As the ranking correlations shows, it is certain that the two models are very similar when they are used for genetic evaluation. But, in conclusion, we can say that for a better lactation curve estimation it is recommending to use test-day model for dairy cattle.

Leibniz A-algebras
Authors: Towers David A.
Published: November 2020

A finite-dimensional Lie algebra is called an A-algebra if all of its nilpotent subalgebras are abelian. These arise in the study of constant Yang-Mills potentials and have also been particularly important in relation to the problem of describing residually finite varieties. They have been studied by several authors, including Bakhturin, Dallmer, Drensky, Sheina, Premet, Semenov, Towers and Varea. In this paper we establish generalisations of many of these results to Leibniz algebras.

Published: November 2020

The accumulators utilized in electric transport differ from those of other applications. Their main features are high capacity, minimum size and weight, and reasonable price. There is extensive research worldwide to improve the battery technology. The aim of the research is to create a mathematical model of an electric vehicle that can capture the vehicle speed curve as a data input to generate the consumed and recovered battery current, which can allow the battery parameters to be analysed and conclude whether the vehicle can perform the trip around the city route with the selected battery parameters. This model serves as a tool to simplify and speed up the necessary calculations and to examine individual sections of the route and their impact on the battery. To complete this task, a simplified electric transport mathematical model gives an opportunity to check if the selected battery can be used in the electrical public transport of the city. The input parameters of the model are the parameters of electrical transport. Simulation of the most popular types of batteries has been performed for two routes of buses in Jelgava in order to determine whether the chosen batteries can provide the necessary bus movement. The mathematical model has been developed in the MATLAB/Simulink software. A GPS mobile application SpeedTracker has been used for data logging.

Published: November 2020

The operation system determines the efficiency of the intended use of radio equipment. The operation system includes radio equipment, documentation, operational resources, personnel, processes, data processing algorithms, etc. The operation process is associated with conditions of priori uncertainty of models, parameters, external factors, etc. The main element for monitoring is technical condition of radio equipment. In a general case, this condition can deteriorate. The problems of technical condition deterioration analysis can be considered in terms of changepoint study. The present paper concentrates on the problem of synthesis and analysis of method for changepoint detection during radio equipment operation. The detection algorithm is constructed based on Neyman–Pearson criterion with sample size accumulation. During algorithm synthesis the thresholds were calculated according to Bellman’s approach. The problem of synthesis and analysis was solved by two methods: analytically and using statistical modelling. The efficiency measures for this algorithm are the probability of correct detection and mean time of decision making. The proposed algorithm has advantages in mean time of decision making compared with CUSUM detection method.

Published: November 2020

The biogas produced in municipal wastewater-treatment plants (WWTP) should be cleaned before it can be used as a fuel in internal combustion engines. Efficient running of such engines is possible only subject to using high quality biogas and lubricating oil. Otherwise, biogas impurities in course of complex chemical reactions may form deposits on various engine parts as well as seriously contaminate the lubricating oil. In this paper, mineral deposits containing high concentration of bismuth, silicon, sulphur, calcium and zinc are studied. Silicon deposits demonstrating strong friction properties are formed during combustion of volatile silica compounds. As these deposits build up, abrasion problems, ignition failure and even engine failure result. The bismuth containing deposits comes from bearings degradation, zinc and calcium were derived from the additives present in commercially available lubricating oil, while lead, aluminium, copper, nickel, iron and chromium were introduced by engine wear phenomena. The highest bismuth content was located at the engine cylinder heads and the lowest at the exhaust elements, whereas highest calcium content was registered on the pistons. Silicon containing deposits are highest in the exhaust and lowest at the engine head. Zinc deposits are highest at the piston.

Published: November 2020

The paper presents results of the measurements of the tropospheric ozone (O3) concentration and meteorological parameters: temperature, air pressure, relative humidity, speed and wind direction. The data were collected from January 2016 to December 2016 at station located in locality Centre (Banja Luka), Republic of Srpska, Bosnia and Herzegovina. Ozone is one of the most harmful pollutants to plants and health and highly reactive secondary pollutant. The present study covers investigation of the relationship between the concentration of ozone and meteorological parameters as well as time variations of ozone concentration (by hours, months, seasons). This topic has not been studied up to now in this region, although the recent research data indicates that there is a correlation between them and previously obtained from the world’s relevant scientific centres, as already cited above. Statistical analysis confirms string of rolls, which shows directional connection between tropospheric ozone and meteorological parameters, specially temperature (r = 0.148), air pressure (r = –0.292) and relative humidity (r = –0.292). These parameters are the most important meteorological factors influencing the variation in ozone levels during the research. The correlation ozone concentrations with speed and direction of wind is not significant, like other parameters.

Published: November 2020

The new coronavirus (COVID-19) outbreak was declared a pandemic by the World Health Organization on March 11, 2020. Since then, important changes have been observed in the medical world, both in terms of patient management and patient presentations to the hospital. A dramatic decrease in the number of cardiovascular emergencies presenting to the emergency rooms has been reported in every country affected by the COVID-19 pandemic. This resulted mainly from the fear of patients to present at the hospital due to the risk of infection with the new coronavirus. Moreover, a significant increase in the time spent for investigations and specialized treatment has been reported for patients suffering from acute cardiovascular diseases. This adds to the longer times reported from symptom onset to presentation, and also to the longer period spent for triage in the emergency room. The aim of this paper is to highlight the dramatic reduction in the number of cardiovascular emergencies during the COVID-19 period and its possible explanations.
“OMO T’O MO ‘YA’RE LOJU” (A child that despises his mother) narratives cultural value of motherhood in Jimi Solanke’s music
Authors: Omotoso Gbenga , Adekogbe Olatunbosun Samuel , Daramola Olusanjo Mathew Abayomi
Published: November 2020

Within the traditional African setting, the values of an African mother in the domestic and societal ambience have called for great concerns. Akinjobi (2011, p. 2) examines African Motherhood as a sacred as well as a powerful spiritual component in the nurturing and development of an African child. The scope of this paper therefore, is to examine the position of Jimi Solanke on the values of African mothers as advocated in some of his purposively selected songs which address the values and position of motherhood as caretakers of children and strongholds in African homes. The paper adopts oral interview, the theory of Womanism and Feminism as rightly observed by Sotunsa (2008, pp. 227–234) as its methodological approaches and largely concentrates on the experience of an African mother, the family relationship as well as the importance of motherhood in her role as an African child nurturer and developer. The paper finds out that Jimi Solanke has not only appraised the values of African mothers, but also expressed severe consequences on any African child who despised or despoiled an African mother.

Published: November 2020

Background: Heart transplantation is still the treatment of choice in patients with end-stage heart failure, refractory to medical treatment, in NYHA class III and IV, with dilated cardiomyopathy of various etiologies, including post-myocardial infarction.

Objective: The aim of the study was to provide a descriptive analysis of the clinical, laboratory, and imaging parameters of patients undergoing heart transplantation during the pre- and postoperative period, as well as postoperative complications (including infections) and death rates.

Material and methods: The variables collected from 53 patients who underwent a heart transplant were: age at heart transplant, gender, diagnosis at hospitalization, comorbidities, pre- and postoperative virology, pre- and postoperative laboratory analyses, pre- and postoperative echocardiography, post-transplant infections, complications, and treatment before and after the surgery.

Results: Mean age at the time of transplant was 40.72 ± 14.07 years, and the majority (84.91%) of patients were males. The mean age of the donors was 31.92 ± 10.59 years. A proportion of 60.40% of patients were included in functional class NYHA IV, and 98.1% presented dilative cardiomyopathy of which 49.06% was due to previous myocardial infarction. No significant differences were observed between preand postoperative viral and bacterial serology. Left ventricular ejection fraction was significantly higher in the transplanted heart, and cardiac chamber diameters were significantly smaller after the transplant. Postoperative complications included 7 confirmed infections and 16 deaths, of which 5 had occurred during the surgical procedure.

Conclusions: The present study brings important information in regard to the pre- and postoperative evaluation of patients with end-stage heart failure undergoing cardiac transplantation, from a clinical, laboratory, and imaging point of view, as well as in regard to postoperative complications and death.
Academic Autonomy in the Contemporary University
Authors: Prawelska-Skrzypek Grażyna
Published: November 2020

Objective: The purpose of this article is to show changes in the understanding of academic autonomy and the manifestations of its erosion, by appropriating this value to legitimise the increase in managerial autonomy, discrediting the value of community autonomy and increasingly restricting individual academic autonomy.

Methodology: The article is based on a critical analysis of the literature dealing with the reality of the functioning of autonomy in higher education institutions and materials related to the implementation of contemporary higher education reforms - mainly in Poland.

Findings: Changes in the perception of autonomy, threats to institutional and individual autonomy resulting from the uncritical subordination of transformations of higher education to the new public management concept as well as institutional isomorphism are presented.

Value Added: Attention has also been paid to ignoring the critical discourse on the consequences of too-one-sided transformation of higher education institutions, losing key values, whose carrier is community and individual autonomy – both academic teachers, for whom it is a necessary condition for the development of didactic and scientific creativity, as well as students who only in a situation of feeling are able to take responsibility for their own development.

Recommendations: Individual autonomy and participatory management, which determine creative activity and academic entrepreneurship, should be a particular concern for university managers. It is necessary to undertake research on the autonomy of students as members of the academic community.
Exploring The Body–Landscape Relationship Through Dance Film
Authors: Hoffmann Flavia Devonas
Published: November 2020

In this paper, I reflect on the body–landscape relationship based on my experience with directing and choreographing my dance film Human Habitat in which a dancer takes us on a journey from a sustainable to a destructive relationship with the Arctic landscape. I outline the background and thoughts involved in producing a dance film in the Arctic and analyse the characteristics of the dancer’s bodily interventions with the landscape. I investigate the properties of being embedded in a processual landscape and examine the consequences of these properties for choreographing movement in a landscape. I further outline how the film evokes kinaesthetic empathy and therefore fulfils my intention of bringing the Arctic into people’s awareness. My examination has a phenomenological approach, and I draw on processual theories of landscape, material specificity and kinaesthetic empathy.

To collect permeability data and establish its database of fertilizer nutrients and water vapor through different polymer membranes for the development of polymer-coated fertilizer, the permeabilities of N-, P-, and K-nutrient from saturated aqueous of urea, NaH2PO4 and KCl solution and the permeability of water vapor through the membranes of poly lactic acid (PLA), its blends with polystyrene (PS), and its composites with humic acid (HA) particles were determined experimentally at the temperatures of 288, 298, and 308 K, respectively. The effects of the addition of PS and HA particles, temperature, and coating thickness on the permeability of fertilizer nutrient and water vapor were investigated. It was found that the addition of PS and HA increased the permeability for both the fertilizer nutrients and water vapor. The increase in temperature raised the permeability of N-, P-, and K-nutrient while decrease the permeability of water vapor in the range studied.
The Trauma of Loss as a Turning Point in Elizabeth Gaskell’s Works
Authors: Vázquez Blanca Puchol
Published: November 2020

The aim of this paper is to look into how Elizabeth Gaskell reflects trauma in her literary works and what she may have been trying to teach her audience through them. As a social and realist writer, she used narrative as a means to denounce the evils of her time, many of which give rise to social traumas. However, this paper will focus on more personal traumas, particularly the trauma of loss, and also how Gaskell handles these traumatic experiences in her writings. With this purpose in mind, it is important to consider Gaskell’s own experience, how she overcame her own traumatic losses and how she used fiction both to reflect her experience and as a form of therapy. At the end of this paper, we will establish how Gaskell uses traumatic losses as turning points throughout her literary works.
The Seriality of Stephen King’s Overlook Hotel – a Transmedial Maze
Authors: Vujanov Jovana
Published: November 2020

This paper investigates three different medial instances of the Overlook Hotel, a space originally hailing from Stephen King’s The Shining. Based on close readings of King’s novel, Stanley Kubrick’s adaptation and a level in the action RPG Vampire the Masquerade: Bloodlines by Troika Games, the following text argues that the Overlook is a serial figure founded on the concept of malignant space in possession of a potent, and often overwhelming, story of violence that despite attempts at its repression cannot be silenced, as in the tradition of the Gothic ghost story. This basic formula is then traced through different media – the novel, film, and video game – where it is seen as gradually shifting its focus from the fictional characters to the recipient, which represents the intersection between the particular affordances of the respective media and the figure of a spatially-bound aggressive storyteller.
The Power of Recipes: Culinary Practice as a Strategy to Deconstruct Arab-American Identity in Diana Abu-Jaber’s Crescent
Authors: Berrebbah Ishak
Published: November 2020

Crescent (2003) is an example of the kind of Arab-American literature that has emerged noticeably in the early years of the 21st century. It signifies a hypothesis that culinary practice is an essential cultural component for diasporic figures to define their identities, especially in a multi-cultural society. These figures embrace such component to strategically define themselves and assert their belonging and affiliation to their original homelands. This paper, as such, examines the extent to which Arab-American characters in the novel, namely Sirine and Han, consider culinary practice as a key tool to understanding their identity, locate themselves in a multi-cultural society, and re-discover their true belonging. The study of this novel shows that culinary practices, as indicated in the narratives, deconstruct Arab-American identity through various dimensions, including memory, nostalgia, hybridity, and essentialism. In addition to employing critical and analytical approaches to the novel, this paper relies on a socio-cultural conceptual framework based on perspectives of prominent critics and theorists such as Homi Bhabha, Brinda Mehta, Dallen Timothy, and Stuart Hall, to name a few.
The Use of Discourse Markers in Academic Writing by In-Service Primary School Teachers of English
Authors: Kapranov Oleksandr
Published: November 2020

This paper presents and discusses a computer-assisted study that seeks to investigate the use of discourse markers (“DMs”) in academic writing in English as a Foreign Language (“EFL”) by a group of in-service primary school teachers (“participants”). The aim of the study is to establish whether or not there would be differences in the use of DMs in the corpus of academic writing in EFL in literature and linguistics written by the participants, who concurrently with teaching EFL at a range of primary schools are enrolled in an in-service tertiary course in English. The corpus of the study consists of the participants’ i) reflective essays in English linguistics and children’s literature in English, respectively, and ii) analytic explanatory essays in English linguistics and children’s literature, respectively. The corpus of the participants’ essays was analysed quantitatively in order to identify the frequency of DMs per 1,000 words. The results of the quantitative data analysis indicated that the participants’ use of DMs seemed to be, primarily, determined by i) genre conventions of academic writing in English associated with reflective essays and analytic explanatory essays and ii) the participants’ individual preferences. These findings are further presented and discussed in the paper.
Football Clubs Drowned by Players
Authors: Perechuda Igor
Published: November 2020

Introduction. The insolvency in football was explained by the underperformance of a football club, either in terms of its ability to achieve playing results which depends on the quality of players on the staff, or in terms of its ability to generate a level of revenue consistent with performance in the league. Hence, two questions were addressed in the study: how deep will the European football crisis be after 2020 and are payrolls the most sensitive factor of football business performance?

Material and Methods. The study was based on the European football clubs data derived from the annual financial statement. A descriptive statistics analysis was performed in order to find out how significant salary indicators are in comparison to other football clubs’ performance measures. In order to establish the scale of changes in football finance in 2020, a basic stress test analysis was implemented.

Results. The study established that salary to revenue indicator is one of the most significant for football clubs’ performance. Thus, as the first step, the analysis of revenue reduction was elaborated and in the second step, the analysis of the reduction of salaries was performed. The presented stress test scenario implied that the situation of European football would change dramatically under the assumption of 50% reduction of the annual revenue.

Conclusions. The study established that the football clubs’situation is too serious not to be carefully managed due to cost and revenue performance.

Published: November 2020

A low-pressure gas supply system for dual fuel engines was designed to transport liquid natural gas from a storage tank to a dual fuel engine and gasify it during transportation. The heat exchange area and pressure drop in the spiral- wound heat exchanger, the volume of the buffer tank and the pressure drop in the pipeline of the gas supply system were calculated by programming using Python. Experiments were carried out during the process of starting and running the dual fuel engine using this gas supply system. Experimental data show that the gas supply system can supply gas stably during the process and ensure the stable operation of the dual fuel engine. The effects of the parameters of natural gas and ethylene glycol solution on the heat exchange area of the spiral-wound heat exchanger and the volume of the buffer tank in the gas supply system were studied. The results show that the heat exchange area calculated according to pure methane can adapt to the case of non-pure methane. The temperature difference between natural gas and ethylene glycol solution should be increased in order to reduce the heat exchange area. The heat exchange area selected according to the high pressure of natural gas can adapt to the low pressure of natural gas. The volume of the buffer tank should be selected according to the situation of the minimum methane content to adapt to the situation of high methane content. The main influencing factor in selecting the volume of the buffer tank is the natural gas flow. The results can provide guidance for the design of the gas supply system for dual fuel engines.
Design Analysis of Hybrid Gas Turbine‒Fuel Cell Power Plant in Stationary and Marine Applications
Authors: Kwaśniewski Tomasz , Piwowarski Marian
Published: November 2020

The paper concerns the design analysis of a hybrid gas turbine power plant with a fuel cell (stack). The aim of this work was to find the most favourable variant of the medium capacity (approximately 10 MW) hybrid system. In the article, computational analysis of two variants of such a system was carried out. The analysis made it possible to calculate the capacity, efficiency of both variants and other parameters like the flue gas temperature. The paper shows that such hybrid cycles can theoretically achieve extremely high efficiency over 60%. The most favourable one was selected for further detailed thermodynamic and flow calculations. As part of this calculation, a multi-stage axial compressor, axial turbine, fuel cell (stack) and regenerative heat exchanger were designed. Then an analysis of the profitability of the installation was carried out, which showed that the current state of development of this technology and its cost make the project unprofitable. For several years, however, tendencies of decreasing prices of fuel cells have been observed, which allows the conclusion that hybrid systems will start to be created. This may apply to both stationary and marine applications. Hybrid solutions related to electrical power transmission, including fuel cells, are real and very promising for smaller car ferries and shorter ferry routes.

Published: November 2020

The paper addresses a topical and important issue for national economic activity, highlighting the important role that human capital has in ensuring economic development and growth. Given the increasingly dynamic and turbulent economic and social context, as a result of the expansion of the phenomena circumscribed by globalization, continuous training through education and the level of health of the population remain the main pillars in ensuring the competitiveness of human capital. Considering this reality, the paper presents a detailed analysis of Romania's position regarding the investment in education and health in a European context and the main elements that characterize the national human capital. By identifying the vulnerabilities associated with the qualitative and quantitative structure of the national human resource, a set of proposals and recommendations are formulated meant to constitute possible solutions for the reported problems. The main conclusions deriving from the study strengthen the hypothesis according to which the return of different forms of professional training is ensured by investing in education and health and represents the conditions of a competitive economic environment in which human capital is properly capitalized.

The subject of the study was fitness services and interaction with consumers of its. It has been identified the main criteria for evaluating the fitness service by customers in process of decisions and selection of the fitness facilities for a visit Surveys of the youth segment of fitness consumers in Kharkiv were conducted and results were processed. The fitness clubs were studied in terms of communicative components of social media marketing to improve their interaction with customers. The research goal was the development computer model for multi-criteria evaluation of fitness centers and their work from clients point of view. As a modeling methodology, we proposed use fuzzy logic. As the instrument for implementation of the model specialized software FuzzyToolBox was chosen. Originally put forward the hypothesis about the possibility, reliability, simplicity and effectiveness of such an approach to modeling of the consumer evaluation of the fitness service, was confirmed as a result of the numerical calculations for fitness clubs in Kharkiv. The developed model can be applied to thetasks of multicriteria estimation of similar services provided to the population of different categories, such as: health-improving sports activities, outdoor activities, spa, water procedures, mass physical training, health-improving, rehabilitation gymnastics, amateur sports etc.

In this study we reveal the measures taken by the Council of the European Union in the field of VAT to support SMEs and the reasons that led the Council of the European Union to take these decisions. It is also indicated the general definition of SMEs in European law as it has been taken up by various other authors, as well as the supportive behavior of SMEs that the European Commission has always had. On the other hand, we carried out a study that included variables defining SMEs in three fields of activity from four countries, located territorially in different areas of the European Union and we identified, using statistical correlation, different coefficients of correlation between the value added the number of SMEs, the number of people employed by SMEs, their turnover in that field of activity. The correlation coefficients that indicated a strong / moderate linearity link indicated that the measures taken by the European Union, through the Council and the European Commission, are welcome as the added value in many areas of activity shows a strong correlation with the number of taxable persons, the number employees of those taxable persons and their turnover.
Conceptualizing a Framework: A Critical Review of the Development of Change Management Theories

Published: November 2020

Although approaches to manage change dated back to as early as human history, managing effective change is still the topic of today’s debates. One of the undeniable facts about this is that change per se keeps changing, and so does its management methodology. While this fact comes, on the one hand, to validate the reason why none of the early theories stands relevant across time, it, on the other hand, proofs that change methodology is certainly fluid, giving no room for an approach to really last. An effective change is achievable [not] by a prescription, but by a thorough consolidation of the various aspects relevant to change. This paper aims therefore at identifying those [managerial] aspects of change, in hope that they could be used to construct a common base to deal with change. To that end, relevant change management hypotheses, approaches, theories dated back to the 50s are taken for thorough reviews. Results from this digest confirm that to manage change, one must factor in change type, change process, and change elements, and yet, to manage it effectively, one must go further to ensure that all the above factors work well together as they are all symbiotically related.
