Abstract
In general, the treatment of dentin hyperesthesia can be performed either at home or in the dentist’s office. The therapeutic approach aims at the use of products, which decrease the excitability of pulp nociceptors or reduce the permeability of the dentin canals. The purpose of this study is to compare the efficiency in the treatment of dentin hyperesthesia of a product containing potassium nitrate, compared to another product using Recaldent™ Technology. The results of this study indicated a significant decrease in pain sensitivity both after application of the product using Recaldent™ Technology and after the product containing potassium nitrate, the results being slightly in favour of the first product.

Abstract
A number of nine benzylidene-4-nitroanilines were synthesized by condensation method. The formation of the substituted (E)-N-benzylidene-4-nitrobenzenamines has been confirmed from their physical and Ultra-Violet, Infra-Red, NMR spectral data. The evaluation of antimicrobial screening of substituted (E)-N-benzylidene-4-nitrobenzenamines was conducted by using standard Bauer-Kirby method. Three gram-positive microbes namely Bacillus subtilis, Micrococcus luteus and Staphylococcus aureus, and two gram-negative microbes, Escherichia coli and Pseudomonas aeruginosa, were used for the antibacterial evaluation. The antifungal activities against Aspergillus niger and Penicilium scup fungal species were also performed. A good antibacterial effect has been possessed by some of the substituted (E)-N-benzylidene-4-nitrobenzenamines on the microorganisms utilized in the present study

Abstract
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.

Published: November 2020

Abstract
The objective of this paper is to analyze the control system that the media offered to Russian disinformation campaigns in a supposed context of hybrid warfare. The exposure of the news offered by the main media channels allows the analysis of the concept of hybrid warfare to be concentrated and its comparison with the traditional strategic conception, in order to determine if the activities in question can be classified in this type of conflict. Information warfare and related components such as cyber warfare, electronic warfare and more, are becoming increasingly complex and can be used both defensively and offensively in the current security context offered by the national media.
Division algebras that generalize Dickson semifields
Authors: Thompson Daniel 
Published: November 2020

Abstract
We generalize Knuth's construction of Case I semifields quadratic over a weak nucleus, also known as generalized Dickson semifields, by doubling of central simple algebras. We thus obtain division algebras of dimension 2s
2 by doubling central division algebras of degree s. Results on isomorphisms and automorphisms of these algebras are obtained in certain cases.
Leibniz A-algebras
Authors: Towers David A. 
Published: November 2020

Abstract
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

Abstract
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.

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Published: November 2020

Abstract
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

Abstract

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

Abstract

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

Abstract
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.

Abstract
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.
