El mito de Perséfone y el conflicto de la maternidad en Mother love, de Rita Dove
Authors: Salcedo González Cristina
Published: December 2020

Este artículo se propone estudiar de qué manera la modernidad introduce nuevas formas de interpretar el vínculo mítico entre Perséfone y Deméter. Para lograr este objetivo, se partirá, en primer lugar, de un estudio de las versiones clásicas de dicha relación y, en segundo lugar, de algunas interpretaciones influyentes ofrecidas en la modernidad. En tercer lugar, se analizará en detalle el acercamiento particular al vínculo madre-hija que propone Rita Dove en su poemario Mother Love (1995) y se desentrañarán las estrategias que esta escritora utiliza para alejarse de la visión idealizada del vínculo y así invocar una manera más compleja y rica de entender las identidades femeninas y, también, los vínculos entre mujeres.
Zur Interessenabwägung im Rahmen des Auswirkungsprinzips
Authors: Stockmann Kurt
Published: December 2020

Der Beitrag diskutiert die These, dass bei der extraterritorialen Anwendung nationalen Kartellrechts über die Anforderungen einer sinnvollen Anknüpfung hinaus ein völkerrechtliches Gebot der Interessensabwägung zu beachten sei. Er untersucht, ob sich diese These auf Völkergewohnheitsrecht stützen kann und ob die Voraussetzungen hierfür erfüllt sind. Ausgewertet werden hierzu die einschlägige Verwaltungspraxis und Rechtsprechung in Deutschland, der Europäischen Union und den USA. Das Ergebnis ist, dass kein völkerrechtlich verbindliches Gebot zur Interessenabwägung besteht und dass mit der Entstehung eines solchen Gebots auch nicht zu rechnen ist. Anschließend werden multilaterale, bilaterale und unilaterale Instrumentarien und Ansätze mit Blick auf diese drei Rechtsordnungen identifiziert, die eine Berücksichtigung ausländischer Interessen in Konfliktfällen unter anderen als völkerrechtlichn Gesichtspunkten vorgeben können oder zulassen. Angesprochen wird schließlich die Frage, wie in Deutschland in solchen Fällen entschieden werden kann und ob ggf. hierbei für bestimmte Arten von Fällen auch der Ministerin oder dem Minister für Wirtschaft und Energie eine Rolle zugeschrieben werden sollte.
The Lives of Women in Plutarch’s Lives
Authors: Juchnevičienė Nijolė
Published: December 2020

Plutarch’s works often serve as a starting point for feminist criticism – the writer is called both a feminist who surpassed his times and a spokesperson for the traditional patriarchal society who sees women as passive and inferior to men. Others are certain that Plutarch hates women and atributes all possible character flaws to them. According to some, Plutarch despises educated women, yet others, contrarily, state that he enjoyed the company of educated women no less than that of educated men. Such a vast range of different expert opinions may be due to Plutarch’s vast literary legacy as well as the peculiarity of his way of thinking and his “generic sensibility”: the tendency to change his approach in consideration of different generic demands. Nevertheless, it is impossible to disagree that Plutarch did write the lives of men, and not of women. However, in the remaining Lives of famous Greeks and Romans, we meet plenty of women whose acts and moral principles may serve as examples not only for women, but also for men. The aim of this article is to demonstrate that Plutarch, despite of sometimes relying on stereotypes, regards women according to the same ethical principles as he applies to men. Plutarch depicts women not as passive and submissive, but as autonomous and mature characters who are active not only in their private world, but in the political world too. They overstep the traditional social boundaries of the stereotype “feminine matrix.” He accentuates two of women’s social roles that, according to his judgement, are of the greatest importance: motherhood and partnership. In Plutarch’s narrative, women are associated with love – the selfless motherly love, or marital love based on the community of thoughts and feelings. Plutarch draws attention not to the physical beauty of women, which is traditionally related to feminine sexuality in masculine psychology, but to the integrity of their characters. Love between a husband and wife, based not only on eros, but on devotion and friendship, is the primary representation of erotic love in his Lives.
Parmenides and M. Karagatsis (Reflection of Myth in Fiction)*
Authors: Goncharko Oksana , Eloeva Fatima , Romanenko Yury
Published: December 2020

The paper aims to show some structural parallels between the concept of motion as developed by Parmenides (5th c. BC) and the expression of the phenomena of motion in the story A Solitary Voyage to the Island Cythera by the Greek writer M. Karagatsis (1908–1960). The novelette of M. Karagatsis is interpreted as a parmenidean “motionless motion” reflexion. It is argued that M. Karagatsis’s story is structurally and essentially related to the Parmenidean poem On Nature, treating the consideration of motion as one of the impossible properties of being; and more obviously refers to certain poems by Constantine Cavafy (1863–1993), which also contain the idea of the meaninglessness of the difference between κίνησις and ἀκινησία. Thus, the concepts of κίνησις and ἀκινησία in the story by M. Karagatsis echo both the Parmenidean ideas and the Cavafy’s images of movement.
Rocket engine thrust vector control by detonation product injection into the supersonic portion of the nozzle

For solving non-traditional problems of rocket flight control, in particular, for the conditions of impact of a nuclear explosion, non-traditional approaches to the organization of the thrust vector control of a rocket engine are required. Various schemes of gas-dynamic thrust vector control systems that counteract impact actions on the rocket were studied. It was found that the dynamic characteristics of traditional gas-dynamic thrust vector control systems do not allow one to solve the problem of counteracting impact actions on the rocket. Appropriate dynamic characteristics can provide a perturbation of the supersonic flow by injecting into the nozzle the detonation products with the main shock wave propagating in the supersonic flow. This way to perturb the supersonic flow in a rocket engine nozzle is investigated in this paper. In order to identify the principles of producing control forces and provide a perturbation of the supersonic flow by injecting into the nozzle the detonation products with the main shock wave propagating in the supersonic flow, a computer simulation of the nozzle flow was performed. The nozzle of the 11D25 engine developed by Yuzhnoye State Design Office and used in the third stage of the Cyclone-3 launch vehicle was taken as a basis. The thrust vector control scheme relies on the use of the main fuel component detonation. The evolution of the detonation wave in the supersonic flow of the combustion chamber nozzle was simulated numerically. According to the nature of the perturbation propagation in the nozzle, the lateral force from the perturbation has an alternating character with the perturbation stabilization in sign and magnitude when approaching the critical nozzle section. The value of the relative lateral force is sufficient for counteracting large disturbing moments of short duration. Thus, the force factors that can be used to control the rocket engine thrust vector are identified. Further research should focus on finding the optimal location of the detonation product injection in order to prevent mutual compensation of force factors.

The aim of the article is to approximate optimal relative control of an underactuated spacecraft using reinforcement learning and to study the influence of various factors on the quality of such a solution. In the course of this study, methods of theoretical mechanics, control theory, stability theory, machine learning, and computer modeling were used. The problem of in-plane spacecraft relative control using only control actions applied tangentially to the orbit is considered. This approach makes it possible to reduce the propellant consumption of reactive actuators and to simplify the architecture of the control system. However, in some cases, methods of the classical control theory do not allow one to obtain acceptable results. In this regard, the possibility of solving this problem by reinforcement learning methods has been investigated, which allows designers to find control algorithms close to optimal ones as a result of interactions of the control system with the plant using a reinforcement signal characterizing the quality of control actions. The well-known quadratic criterion is used as a reinforcement signal, which makes it possible to take into account both the accuracy requirements and the control costs. A search for control actions based on reinforcement learning is made using the policy iteration algorithm. This algorithm is implemented using the actor–critic architecture. Various representations of the actor for control law implementation and the critic for obtaining value function estimates using neural network approximators are considered. It is shown that the optimal control approximation accuracy depends on a number of features, namely, an appropriate structure of the approximators, the neural network parameter updating method, and the learning algorithm parameters. The investigated approach makes it possible to solve the considered class of control problems for controllers of different structures. Moreover, the approach allows the control system to refine its control algorithms during the spacecraft operation.
Calculation of a 3D turbulent flow in aircraft gas turbine engine ducts
Authors:   Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine, Kvasha Yu.A.
Published: December 2020

This work is devoted to the development of approaches to the numerical simulation of 3D turbulent gas flows in different ducts of aircraft gas turbine engines, in particular in inlet device ducts. Inlet devices must provide large values of the total pressure recovery factor and flow uniformity at the engine compressor inlet. The aim of this work is the verification of the operability of a technique developed earlier for the calculation of the parameters of a 3D turbulent flow in complex-shape ducts. The basic approach is a numerical simulation of 3D turbulent gas flows on the basis of the complete averaged Navier¬–Stokes equations and a two-parameter turbulence model. The proposed technique of numerical simulation of a 3D gas flow was tested by calculating a 3D laminar flow in a square pipe bent at a right angle. The calculated flow pattern is in satisfactory agreement with the experimental data on the flow structure in a pipe elbow reported in the literature. Based on a numerical simulation of a 3D turbulent flow in the air duct of one of the air intake configurations for an aircraft turboprop engine, the efficiency of that configuration is assessed. The calculated flow parameter nonuniformity at the air intake outlet, i. e., at the compressor inlet, is compared with that obtained earlier for another air intake configuration for the same engine. It is pointed out that the air intake configuration considered earlier provides a much more uniform flow parameter distribution at the engine compressor inlet. On the whole, this work shows that the quality of subsonic air intakes for aircraft gas turbine engines can be assessed using the proposed numerical technique of 3D gas flow simulation. The results obtained may be used in the aerodynamic improvement of inlet devices for aircraft engines of different types.
Calculation of the interaction of a supersonic jet with a flat obstacle inclined off the jet axis
Authors:   Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine, Halynskyi V.P.
Published: December 2020

This paper presents results of a numerical solution of the model problem of the interaction of a plane supersonic jet with a semiinfinite flat plate inclinable off the jet axis. The paper is devoted to the study of the flow parameters in the jet flow field and the pressure distribution over the plate surface as a function of the plate inclination. The aim of the paper is to obtain the flow parameters in the jet flow field and the pressure distribution over the plate surface as a function of the plate inclination angle and front edge position. To obtain numerical results, marching algorithms in the inviscid gas and viscous layer approximation were used. At specified values of the supersonic underexpanded/overexpanded jet parameters, calculations were conducted in the plate inclination angle range of 0 to 20?. The position of the plate front edge was specified by two coordinates: a longitudinal and a transversal one, and in the parametric calculations the transversal coordinate was varied at a fixed longitudinal one. The cross-section at which the nonuniform jet field starts to interact with the plate was determined as a function of both the plate front edge position and the plate inclination. The numerical study showed the following: with increasing plate inclination angle, the oscillation frequencies of the flow parameters in the jet flow field and on the plate surface decrease, while their oscillation amplitudes increase, and the position of the maximum pressure point on the plate surface depends on the initial position of the plate front edge and may not coincide with the cross-section at which the jet–plate interaction starts. The results obtained may be used in qualitative estimation of the effect of different parameters in the jet flow field.

At present, nearly all countries of the world develop and implement measures aimed to increase the competitiveness and efficiency of their railways. One of the priority lines is to increase the carrying capacity of freight trains. In Ukraine, 18-9817 trucks of axle load 25 tf were developed and adopted as basic ones for new-generation freight cars, and the ITM-73-03 wear-resistant wheel profile of flange thickness 32 mm was developed for them too. The aim of this paper is to study the effect of in-service variation in the wheel and rail profile shape on the spatial oscillations of a freight car with 18-9817 trucks and the ITM-73-03 wheel profile. The paper estimates the effect of in-service variation in the wheel and rail profile shape on the dynamic stability and ride performance of the car under consideration. The wear of wheels with the new profile is predicted by solving the geometrical problem of wheel–rail interaction with account for the mutual horizontal lateral displacements of the wheel and the rail, the wheelset angle of attack and angle of roll, the nonlinearity of the contacting surfaces, and the possibility of their conformal contact. The results of calculation of the spatial oscillations of the car in tangents and curves are presented. It is shown that wear-caused variation in the wheel and rail profile shape has little effect of the dynamic performance of a new-generation freight car with 18-9817 trucks with an increased axle load and the ITM-73-03 wear-resistant wheel profile, its dynamic stability and ride performance remaining at a high level. The use of the above car on the Ukrainian railways fully meets the objectives of home rolling stock renewal: vehicle ride performance improvement, running gear life extension, and vehicle and track wear reduction
Continuous method of second order with constant coefficients for monotone equations in Hilbert space
Authors: Ryazantseva Irina P.
Published: December 2020

Convergence of an implicit second-order iterative method with constant coefficients for nonlinear monotone equations in Hilbert space is investigated. For non-negative solutions of a second-order difference numerical inequality, a top-down estimate is established. This estimate is used to prove the convergence of the iterative method under study. The convergence of the iterative method is established under the assumption that the operator of the equation on a Hilbert space is monotone and satisfies the Lipschitz condition. Sufficient conditions for convergence of proposed method also include some relations connecting parameters that determine the specified properties of the operator in the equation to be solved and coefficients of the second-order difference equation that defines the method to be studied. The parametric support of the proposed method is confirmed by an example. The proposed second-order method with constant coefficients has a better upper estimate of the convergence rate compared to the same method with variable coefficients that was studied earlier.

Published: December 2020

The registration of a 3D model over an image can be seen as the alignment of visual correspondences extracted from these two data. This is a challenging task and it is even more complex when the two images have a different modality. This paper introduces an approach that allows matching features detected in two different modalities: photographs and 3D models, by using a common 2D representation. Our approach is based on a modifcation of the Marching Cubes algorithm aiming to remove ambiguous cases without adding further calculations in each cube. We share the idea about the crucial importance of splitting the equivalence cases into two classes. Considering all the possible states inside/outside in the four corners of a cube side, indeed, there are only four non-trivial cases after eliminating those equivalences through the rotation. The obtained results allow us to validate the feasibility of the proposed methodology.

Authors:   University of Zagreb Faculty of Agriculture, Svetošimunska cesta 25, 10000 Zagreb, Croatia, Ivanković Ante
Published: December 2020

Over the past three decades, the scientific and public interest has been initiated by studies in which the negative effect of milk consumption of beta-casein A1 variant has been observed on consumers’ health. The production of "A2 milk" is one of the ways to economically increase the competitiveness of small and medium-sized dairy farms. Breeders of endangered local breeds are also interested in reaffirmation through production of “A2 milk”. The aim of this study is to determine frequencies of A1 and A2 variants of beta-casein in three commercial and three local breeds of cattle in Croatia, and their relationship with production indicators of commercial breeds in the first three lactations. The genomic DNA was extracted from hair by using a commercial kit, used for determination of CSN2 genotypes by means of PCRRFLP method. Data for milk yield and chemical composition were provided by the central database. The dominant presence of A2 variant beta-casein in the investigated cattle breeds (0.650-0.758) and the increase in the frequency of A2 beta-casein in the population of Simmental and Istrian cattle were determined. The association of A2A2 and A1A1 genotypes of beta-casein with lactation production and milk fat content in the first and second lactation was observed (p <0.05). The dominance of the A2 allelic variation of beta-casein makes the researched conventional and local breeds suitable for the production of "A2 milk. The breeding extension of A2 allelic variation of beta-casein within local breeds of cattle should be carried out carefully not to lose part of the existing genetic variability.

Published: December 2020

Due to the high content of crude protein and high concentration of unsaturated fatty acids, pumpkin seed cake (PSC) could be a good quality feedstuff for ruminants, while extruded linseed (ELS) has already shown some beneficial effect on fatty acids proportion of goat milk. Besides, lactation is the most demanding period when monitoring the metabolic condition of animal. Therefore, the aim of this study was to determine the effect of PSC and ELS replacing soybean meal in diets of dairy goats on blood haemato-chemical parameters and milk quality. A 28 lactating French Alpine dairy goats were monitored within 20 days in early lactation. Diet of each groups had a balanced content of energy and crude protein, and a slight difference in lipid content. Goats in control group (n = 9) received soybean meal and extruded soybean. In experimental groups soybean was partially replaced with ELS (n = 10) or completely with PSC (n = 9). Dietary treatments had no effect on haemato-chemical parameters, although PSC increased concentration of globulins in serum. PSC lowered linoleic acid compared to control. ELS increased proportion of α-linolenic acid, eicosapentaenoic acid, and total n-3 fatty acids in milk. Positive correlations were found between non-esterified fatty acids (NEFA) and ratio C18:1/C15:0, NEFA and ratio C17:0/C15:0, as well as β-hydroxybutyrate and ratio C17:0/C15:0. The replacement of soybean meal with PSC or partially with ELS is feasible with respect to haemato-chemical parameters of early lactating dairy goats, while ELS had much beneficial effect on fatty acids compared to PSC.

Authors:   Kocaeli University, Faculty of Agriculture and Natural Science, Kocaeli, Turkey mail, Tomar Oktay
Published: December 2020

The aim of this study was to use various plants to increase the functional properties of yoghurt. The ethanol extracts of three different plant (Mentha piperita L., Ocimum basilicum L., and Hibiscus sabdariffa L.) extracts were added to the stirred type yoghurts at different ratios (0.1%, 0.3% and 0.5%). The pH values, colour values, antioxidant activity, microbial and sensory attributes of yoghurt were evaluated on the storage days of 0, 7, 14, 21, and 28. The lowest pH values were found at the beginning (4.29) and at the end (3.95) of the storage period in samples containing 0.5% hibiscus extract. The addition of plant extracts in amounts of 0.3% and higher decreased the lightness (L*) value of yoghurt (p<0.05), and the maximum decrease was found in yoghurt samples containing 0.5% hibiscus ethanol extract. The concentrations of added mint and basil extracts increased the yellowness (b*) value (p<0.05), while the addition of hibiscus extract significantly increased the redness value (p<0.05). Hibiscus ethanol extract significantly reduced the growth of total aerobic mesophilic bacteria (TAMB), lactic acid bacteria (LAB) and Lactococcus/ Streptococcus bacteria (p<0.05). The antioxidant activity of all samples increased with adding plant extracts. According to the results of sensory analysis, the addition of 0.1% plant extracts to yoghurts rated higher scores than that of the control sample, but the addition of 0.3% and 0.5% ethanol extracts negatively affected the sensory properties. It can be concluded that adding plant extracts had a positive effect on the sensory and functional properties of yoghurt.

Published: December 2020

Kefiran is an exopolysaccharide (EPS) produced by specific microorganisms in the kefir grain. In this research, kefir grain was activated in various carbon sources (glucose, galactose or lactose) containing medium. The monosaccharides composition of the formed kefiran were determined by a high performance liquid chromatography (HPLC). HPLC with refractive index (RI) detector was used in order to make qualitative and quantitative analysis of sucrose, glucose, galactose, arabinose, xylose, and ribose present in kefiran. Also, the physical properties of differently kefiran formed were determined. The amount of kefiran in the control group and in the sample from the galactose containing medium were determined to be 511.00 and 610.55 mg/L, respectively. The kefiran form obtained from the medium containing galactose was more positively affected than in other media. The apparent viscosity, at a shear rate of 66.0 s-1of the kefiran produced in glucose containing medium, was determined to be 29.2 mPas. The surface morphologies of different kefirans were analysed and roughness parameters were determined by atomic force microscopy (AFM); the maximum height of lumps ranged from 16.80 to 22.10 nm. In this study, of sucrose, glucose, galactose, arabinose, xylose, and ribose were found in sugar composition in all kefiran samples.

Published: December 2020

This study aimed to determine the physicochemical properties and antioxidant activities of dromedary skim colostrum and milk powder produced by freeze-drying. Results of the study showed that skim colostrum powder possessed higher protein content compared to milk powder whereas this latter had greater lactose and ash content. The analysis of mineral content revealed that calcium and magnesium levels were higher in skim colostrum powder while the iron level did not differ significantly between skim colostrum and milk powder. The measurements of colour characteristics indicated that dromedary skim colostrum powder was redder, but less yellow and white than dromedary skim milk powder. Further, dromedary skim milk powder had higher bulk density and tapped bulk density. Protein solubility of skim colostrum powder exceeded that of skim milk powder over a wide range of pH (3-8). The antioxidant activities were evaluated using various in vitro tests, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical scavenging activities, ferric reducing power assay and ferrous chelating activity. Both dromedary skim colostrum and milk powder exhibited antioxidant activities in a dose dependent manner. DPPH and ABTS radical scavenging activities were almost similar for skim colostrum and milk powder whereas ferric reducing power and ferrous chelating activity were more pronounced in dromedary skim colostrum powder whatever the concentration tested. Hence, freeze-drying process could be used as an effective tool for producing powder from dromedary skim colostrum and milk with nutritional and antioxidant properties.

Currently, Vereshchagino has accumulated typical problems for a provincial city (demographic, communal and sociocultural). The visual image of the urban environment is devoid of expressive color. The author believes that Vereshchagino has a unique chance to become a comfortable city for living, a place of attraction for people who through active ascetic practices support and reproduce the sociohistorical identity of the economic structure of the country. This initiative is based on the methodology of geocultural branding of cities and territories. The proposed brand image "Verkhokamskaya Usadba" contains visible and invisible meanings of creativity and asceticism, acting as mental foundations in the author's project of the model strategy of geocultural branding in Vereshchagino.
