Published: June 2021

In recent years, several structure-based properties of the molecular graphs are understood through the chemical graph theory. The molecular graphGGof a molecule consists of vertices and edges, where vertices represent the atoms in a molecule and edges represent the chemical bonds between these atoms. A numerical quantity that gives information related to the topology of the molecular graphs is called a topological index. Several topological indices, contributing to chemical graph theory, have been defined and vastly studied. Recent inclusions in the class of the topological indices are the K-Banhatti indices. In this paper, we established the precise formulas for the first and second K-Banhatti, modified K-Banhatti, K-hyper Banhatti, and hyper Revan indices of silicon carbideSi2C3{{\rm{Si}}}_{2}{{\rm{C}}}_{3}-III[n,m]{\rm{III}}\left[n,m]. In addition, we present the graphical analysis along with the comparison of these indices forSi2C3{{\rm{Si}}}_{2}{{\rm{C}}}_{3}-III[n,m]{\rm{III}}\left[n,m].
Impact of binding mode of low-sulfated hyaluronan to 3D collagen matrices on its osteoinductive effect for human bone marrow stromal cells
Authors: Vogel Sarah , Ullm Franziska , Müller Claudia Damaris , Pompe Tilo , Hempel Ute
Published: June 2021

Synthetically sulfated hyaluronan derivatives were shown to facilitate osteogenic differentiation of human bone marrow stromal cells (hBMSC) by application in solution or incorporated in thin collagen-based coatings. In the presented study, using a biomimetic three-dimensional (3D) cell culture model based on fibrillary collagen I (3D Col matrix), we asked on the impact of binding mode of low sulfated hyaluronan (sHA) in terms of adsorptive and covalent binding on osteogenic differentiation of hBMSC. Both binding modes of sHA induced osteogenic differentiation. Although for adsorptive binding of sHA a strong intracellular uptake of sHA was observed, implicating an intracellular mode of action, covalent binding of sHA to the 3D matrix induced also intense osteoinductive effects pointing towards an extracellular mode of action of sHA in osteogenic differentiation. In summary, the results emphasize the relevance of fibrillary 3D Col matrices as a model to study hBMSC differentiation in vitro in a physiological-like environment and that sHA can display dose-dependent osteoinductive effects in dependence on presentation mode in cell culture scaffolds.
Switched capacitor based single DC source boost multilevel inverter (S2-MLI) featuring isolation based soft charging with minimum device count
Authors: Debela Tamiru , Singh Jiwanjot
Published: June 2021

Multilevel inverters (MLIs) have formed a new wave of interest in research and industry. Switched capacitor-based multilevel inverters are used to avoid the need for multiple separated DC sources compared to cascaded MLIs. However, the inclusion of several capacitors creates problems such as high inrush current, voltage imbalance. To avoid these drawbacks, this paper proposes an isolation-based scheme by using a flyback converter in the switched capacitor multilevel inverter. Further, the overall topology provides step-up AC voltage across the load from a single DC source with fewer power switches. To generate a step-up five-level voltage across the load, switched capacitor-based multilevel inverter needs six power switches and only one capacitor. To get the appropriate switching operation to generate the NL-levels, phase disposition pulse width modulation (PD-PWM) has been developed. The extended nine-level S

-MLI is also discussed in this paper under different conditions as change in input source voltage and dynamic load change. Moreover, to prove the superior performance of switched-capacitor single DC source multilevel inverter (S2-MLI), comparative analysis with existing single DC source MLI has been performed. The effectiveness and feasibility of the proposed topology are tested with varieties of loads by simulation using Matlab/Simulink. To validate the simulation results, hardware implementation has been done of five-level S2-MLI considering resistive and motor load by using DSpace 1103 controller.
Shifted Legendre spectral collocation technique for solving stochastic Volterra–Fredholm integral equations
Authors: Abdelkawy Mohamed A.
Published: June 2021

This paper addresses a spectral collocation technique to treat the stochastic Volterra–Fredholm integral equations (SVF-IEs). The shifted Legendre–Gauss–Radau collocation (SL-GR-C) method is developed for approximating the FSV-IDEs. The principal target in our technique is to transform the SVF-IEs to a system of algebraic equations. For computational purposes, the Brownian motion W(x) is discretized by Lagrange interpolation. While the integral terms are interpolated by Legendre–Gauss–Lobatto quadrature. Some numerical examples are given to test the accuracy and applicability of our technique. Also, an error analysis is introduced for the proposed method.
Infinite line of equilibriums in a novel fractional map with coexisting infinitely many attractors and initial offset boosting
Authors: Almatroud A. Othman , Khennaoui Amina-Aicha , Ouannas Adel , Pham Viet-Thanh
Published: June 2021

The study of the chaotic dynamics in fractional-order discrete-time systems has received great attention in the past years. In this paper, we propose a new 2D fractional map with the simplest algebraic structure reported to date and with an infinite line of equilibrium. The conceived map possesses an interesting property not explored in literature so far, i.e., it is characterized, for various fractional-order values, by the coexistence of various kinds of periodic, chaotic and hyper-chaotic attractors. Bifurcation diagrams, computation of the maximum Lyapunov exponents, phase plots and 0–1 test are reported, with the aim to analyse the dynamics of the 2D fractional map as well as to highlight the coexistence of initial-boosting chaotic and hyperchaotic attractors in commensurate and incommensurate order. Results show that the 2D fractional map has an infinite number of coexistence symmetrical chaotic and hyper-chaotic attractors. Finally, the complexity of the fractional-order map is investigated in detail via approximate entropy.
Schelling’s Narrative Philosophy and Ankersmit’s Narrative Logic – Is There Any Philosophy to Narrative?
Authors: Filutowska Katarzyna
Published: June 2021

This paper considers the problem of a narrative philosophy according to F. W. J. Schelling and narrative logic according to Franklin Ankersmit. Referring to these examples, I ask whether there is any philosophy to narrative at all. First, I discuss Schelling’s views from his unfinished work “The Ages of the World,” as well as his later dialectics of mythology of revelation from the system of the ages of the world. I focus on a dialectics of figurative and speculative order, which is at the core of Schelling’s project to tell philosophy in the form of poetry and demonstrate the origins of Schelling’s narrative philosophy in his early, transcendental thought. Next, I juxtapose my findings with Ankersmit’s analysis of historians’ language. I also consider whether, and how, some of these ideas can be applied in contemporary narrative research.
First North African record of a melanistic common genet (Genetta genetta Linnaeus, 1758)

Published: June 2021

The common genet (Genetta genetta Linnaeus, 1758) is a rare and protected mammal species in Algeria. We report the first melanistic individual of this species ever recorded in North Africa. Such animals have only been recorded in Spain and Portugal so far. It is unclear why melanistic common genets seem to be so rare in its African range. More research is needed to determine the true occurrence of melanistic individuals, and what the evolutionary history of melanism is in common genets.

This article complements the coverage of the status of women in ocean science as contained in the recently published Global Ocean Science Report 2020 – Charting capacity for ocean sustainability. Using the seven Science, Technology and Innovation Gender Objectives (STI GOs) of UNESCO’s SAGA (STEM and Gender Advancement) project, it reviews available information on women’s education and careers in ocean science for some of the countries with the highest numbers of ocean scientists in order to highlight STI GOs of concern. It also provides some information on resources for each STI GO to help institutions to achieve gender equality amongst their ocean science research staff.
Bayesian multivariate Beveridge–Nelson decomposition of I(1) and I(2) series with cointegration
Authors: Murasawa Yasutomo
Published: June 2021

The dynamic IS equation implies that if the real interest rate is I(1), then so is the output growth rate with possible cointegration, and log output is I(2). This paper extends the Beveridge–Nelson decomposition to such a case, and develops a Bayesian method to obtain error bands. The method is valid whether log output is I(1) or I(2). The paper applies the method to US data to estimate the natural rates (or their permanent components) and gaps of output, inflation, interest, and unemployment jointly, and finds that allowing for cointegration gives much bigger estimates of the gaps for all variables.

Published: June 2021

Abián-Vicén, J, Martínez, F, Jiménez, F, and Abián, P. Effects of eccentric single-leg decline squat training performed with different execution times on maximal strength and muscle contraction properties of the knee extensor muscles. J Strength Cond Res 36(11): 3040–3047, 2022—The eccentric phase of the single-leg decline squat (SLDSe) has been described as a method to maximally load the knee extensor and has been used as an easy and effective rehabilitation exercise for patellar tendinopathy. The purpose of this study was to examine the impact of 6-week SLDSe training with 2 technical execution times on changes related to strength and muscle contractile properties. Thirty-six healthy volunteers were randomly divided into 3 groups: a control group (CG, n = 13, no training), a slow training group (n = 11, SLDSe in 6 seconds), and a fast training group (n = 12, SLDSe in 3 seconds). Subjects completed a 6-week SLDSe training program (80% of eccentric one repetation maximum [1RM]) 3 days a week. Pre, post, and 6-week follow-up of maximal dynamic and isometric strength and muscle contractile properties were assessed. After 6 weeks, training maximal loads showed a significant increase (p < 0.05) in 1RM of the SLDSe (∼92–95%), the concentric peak torque at 180°·s−1 (∼38%) and 60°·s−1 (∼25%), and the extension isometric peak torque (∼12%), with no differences between both experimental groups. Moreover, a decrease (p < 0.05) was found in the contraction time of the vastus medialis (VM) and the response time of the 3 analyzed quadriceps muscles. After the 6-week detraining period, there was a decrease in strength in all tests and in both experimental groups (1RM = 28–37%, isometric and isokinetic tests = 7–17%) and all contractile properties returned to baseline, except for the response time of the vastus lateralis in the fast training group and the contraction time of the VM in the STG. In conclusion, the SLDSe training protocol produced significant increases in muscle strength, showing important neuromuscular changes regardless of the technical execution time. It was also found that the training reduced the response and contraction time of the knee extensor musculature.
Simplified Prediction Method of Stress Intensity Factor in Mid-thick Plane in 3D Cracked Body and Its Difference from 2D Handbook Formula
Authors: Kawabata Tomoya , Kosuge Hiroaki , Ozawa Takumi , Mikami Yoshiki
Published: June 2021

The authors have been working to improve the crack tip opening displacement (CTOD) evaluation standard as a fracture parameter for the cleavage-type brittle fracture critical condition of carbon steel. In 2016, WES1108, Standard Test Method for Crack-Tip Opening Displacement (CTOD) Fracture Toughness Measurement, which is the CTOD test standard in Japan, was revised, and subsequently, the CTOD calculation formula of ISO 15653:2010, Metallic Materials – Method of Test for the Determination of Quasistatic Fracture Toughness of Welds, was revised in 2018, focusing on the study of the formula that constitutes the basis of the standard. Similar to the original British Standards equation, the proposed CTOD calculation formula consists of a small-scale yield (SSY) term and a plastic term, but in the SSY term, the two-dimensional (2D) stress intensity factor (SIF) is used. The authors focused on the incorrectness of this treatment derived from the difference between 2D and three-dimensional (3D). Here, two accurate relationships have been explored through systematic finite element method analyses; one is the correlation of the 3D SIF values in the mid-thickness plane and 2D SIF, and the second is the relationship between the actual 3D SIF in mid-thickness and the CTOD in mid-thickness. The KI ratio (K3D/K2D) sharply coincides with the value 1.11, as inferred in several previous pieces of research in the idealistic infinite plate with a crack. However, if the ligament size is finite as in the actual fracture toughness test, the KI ratio drops significantly from 1.11, and in some cases, the KI ratio is less than 1. By unifying these findings, a new precise CTOD formula has been established. Lastly, the study inferred that the error of the calculation formula is improved, especially in small thickness regions, as compared with the current standard proposed in 2016 and 2018 by the authors.

Objective

Male sex is one of the determinants of severe coronavirus diseas-e-2019 (COVID-19). We aimed to characterize sex differences in severe outcomes in adults with diabetes hospitalized for COVID-19.

Methods

We performed a sex-stratified analysis of clinical and biological features and outcomes (i.e. invasive mechanical ventilation (IMV), death, intensive care unit (ICU) admission and home discharge at day 7 (D7) or day 28 (D28)) in 2380 patients with diabetes hospitalized for COVID-19 and included in the nationwide CORONADO observational study (NCT04324736).

Results

The study population was predominantly male (63.5%). After multiple adjustments, female sex was negatively associated with the primary outcome (IMV and/or death, OR: 0.66 (0.49–0.88)), death (OR: 0.49 (0.30–0.79)) and ICU admission (OR: 0.57 (0.43–0.77)) at D7 but only with ICU admission (OR: 0.58 (0.43–0.77)) at D28. Older age and a history of microvascular complications were predictors of death at D28 in both sexes, while chronic obstructive pulmonary disease (COPD) was predictive of death in women only. At admission, C-reactive protein (CRP), aspartate amino transferase (AST) and estimated glomerular filtration rate (eGFR), according to the CKD-EPI formula predicted death in both sexes. Lymphocytopenia was an independent predictor of death in women only, while thrombocytopenia and elevated plasma glucose concentration were predictors of death in men only.

Conclusions

In patients with diabetes admitted for COVID-19, female sex was associated with lower incidence of early severe outcomes, but did not influence the overall in-hospital mortality, suggesting that diabetes mitigates the female protection from COVID-19 severity. Sex-associated biological determinants may be useful to optimize COVID-19 prevention and management in women and men.
CEP164 is essential for efferent duct multiciliogenesis and male fertility
Authors: Hoque Mohammed , Chen Danny , Hess Rex A , Li Feng-Qian , Takemaru Ken-Ichi
Published: June 2021

Cilia are evolutionarily conserved microtubule-based structures that perform diverse biological functions. Cilia are assembled on basal bodies and anchored to the plasma membrane via distal appendages. In the male reproductive tract, multicilia in efferent ducts (EDs) move in a whip-like motion to prevent sperm agglutination. Previously, we demonstrated that the distal appendage protein CEP164 recruits Chibby1 (Cby1) to basal bodies to facilitate basal body docking and ciliogenesis. Mice lacking CEP164 in multiciliated cells (MCCs) (FoxJ1-Cre;CEP164fl/fl) show a significant loss of multicilia in the trachea, oviduct, and ependyma. In addition, we observed male sterility; however, the precise role of CEP164 in male fertility remained unknown. Here, we report that the seminiferous tubules and rete testis of FoxJ1-Cre;CEP164fl/fl mice exhibit substantial dilation, indicative of dysfunctional multicilia in the EDs. We found that multicilia were hardly detectable in the EDs of FoxJ1-Cre;CEP164fl/fl mice although FoxJ1-positive immature cells were present. Sperm aggregation and agglutination were commonly noticeable in the lumen of the seminiferous tubules and EDs of FoxJ1-Cre;CEP164fl/fl mice. In FoxJ1-Cre;CEP164fl/fl mice, the apical localization of Cby1 and the transition zone marker NPHP1 was severely diminished, suggesting basal body docking defects. TEM analysis of EDs further confirmed basal body accumulation in the cytoplasm of MCCs. Collectively, we conclude that male infertility in FoxJ1-Cre;CEP164fl/fl mice is caused by sperm agglutination and obstruction of EDs due to loss of multicilia. Our study, therefore, unravels an essential role of the distal appendage protein CEP164 in male fertility.

To overcome the agglomeration tendency of nanosilver composite hydrogels and to improve their anti-mold properties, a method of preparing N-isopropylacrylamide/acrylic acid/nanosilver composite hydrogel was developed using the free radical polymerization method. The composite hydrogel was characterized via infrared spectroscopy, dynamic light scattering, transmission electron microscopy, and X-ray photoelectron spectroscopy in order to explore the effects of the acrylic acid content on particle size and dispersion properties of the composite hydrogels. The elemental composition, microstructure, and anti-mold properties of the bamboo strips treated with the composite hydrogel were also determined. The results showed that the composite hydrogel prepared using the novel method described in this study had good dispersity. Composite hydrogels with the smallest particle size and optimized dispersion were produced when AAc concentration was 0.64 µL/mL. The composite hydrogel effectively filled and covered the bamboo cells after treatment. Moreover, it displayed good anti-mold properties as well as retaining the color of the bamboo.

Published: June 2021

Measuring the energy consumption and evaluating the efficiency of machining processes is necessary for their optimization and for implementation of cleaner production. The final product quality and the machining process of woodworking are of great interest. The properties of thermally modified wood make it more resistant to fungi, moulds, and ligniperdous insects than natural wood, so it is increasingly used in interior and exterior spaces. This study examined the energy demand of the milling of heat-treated oak wood (Quercus petraea) by ThermoWood® technology. The investigated technological parameters were thermal modification temperature (160 °C, 180 °C, 200 °C, and 220 °C), cutting speed (20 m × s-1, 40 m × s-1, and 60 m × s-1), feed rate (6 m × min-1, 10 m × min-1, and 15 m × min-1), and the material of the cutting tool. As the temperature of the thermal modification increased, the cutting power decreased due to a chemical degradation due to heating and reduced wood density. The lowest energy consumption was observed for the milling of wood treated at 220 °C with a cutting speed of 20 m × s-1, and a feed rate of 6 m × min-1.

Published: June 2021

Embossing is a commonly used design element on printed products and packaging. It enhances the product impression with optical and haptic effects. The material deformation during the embossing of cardboard is normally done using high mechanical pressure between two dies. The use of ultrasound in the embossing process leads to a noticeable reduction of the embossing pressure and a greater embossing precision. However, there is a noticeable heating of the cardboard during the ultrasonic-assisted embossing process. This work aimed to characterise the effects of heating and to understand the reasons for the greater precision with decreased force when ultrasound is used. Therefore, the effects of the thermal ultrasonic energy on the chemical composition and the morphological properties of the fibres were investigated. The findings showed that no noticeable changes occurred in the chemical composition or fibre geometry as a result of the embossing process with ultrasound.
Meaning Construction for Biodynamic Osteopathy Terms in Translation Practice
Authors: Kalinina Irina
Published: June 2021

This article belongs to the interface of terminology and translation studies and aims to describe the principles of meaning construction in the translation of field-specific terms in biodynamic osteopathy. The central problem of the study presented in this paper deals with identification and analysis of measurable components of meaning of terminological units. The data for the study comprises a corpus of 210 English terms in the field of biodynamic osteopathy translated into French, Italian, Russian and Latvian. Following the analysis of the meanings of the terms through their contextual uses, it is possible to assess other factors that contribute to the content of these units.Methodologically, we built a definition for each term based on its context. Next, we investigated the notion of semantic resonance that is relevant for terminological units derived from general language. The study suggests that even in the field of neology where the concepts are borrowed together with the terms, resonance can vary from one language to another, which, as a consequence, highlights the problem of cross-linguistic equivalence in the translation of texts in this field.
Technical Writing as Tralanguage in Favor of a Translation and Productemiccompetence of the Word
Authors: Djelloul Said-Belarbi
Published: June 2021

In translation and traductology, specialists recognize the undeniable relationship between the act of transiting, technical writing and the meaning of the words. However, considerations regarding the problems presented by culture and realia (untranslatable terms) in particular are frequent. It is at the same time the raison d’etre of translation and the source of difficulties. In other words, building a sense of a word or even producing it in case of a failure in the target language is not easy, but is this exercise impossible? If not, what should be done to overcome these pitfalls and cultural difficulties for realia via a translation operation in general and a legal one in particular? Answers to these questions can be found in a proposal entailing a strategic approach, calling on four major factors that the “trauthor” should take into account for the production of the meaning of a word. Finally, a reflection on said factors is made to access the process of ways of teaching for the production of word meaning.

Published: June 2021

Ensuring an attractive commercial appearance of egg yolks involves the introduction to the feed of laying hens of the dyes of various origins. Recently, egg producers have preferred natural dyes, which include carotenoids: lycopene and astaxanthin, which can be deposited in chicken egg yolks. The aim of this study was to determine the quality of egg yolks, colour intensity and carotenoid composition of yolks when oil extracts of lycopene (20, 40 and 60 mg/kg feed) or astaxanthin (10, 20 and 30 mg/kg feed) are included in the chickens’ diet. 45 High Line W36 chickens at the age of 24 weeks were used for the experiment. Feeding laying hens with supplements of lycopene oil extracts at doses of 30, 40 and 60 mg/kg and astaxanthin at doses of 10, 20 and 30 mg/kg of feed for 30 days in increasing concentrations did not affect egg weight, albumen height, Haugh unit, strength and the thickness of the shell. The addition of lycopene to the diet of chickens at doses of 20 mg/kg of feed increased the content of lycopene, unidentified carotenoids and the total content of carotenoids in the yolks, but did not change the intensity of their colour. Increasing the dose of lycopene in the diet of chickens to 40 and 60 mg/kg of feed increased the content of lycopene in yolks and the intensity of their colour to 7.4 and 8.0 points against 5.6–6.1 points in the control, but did not affect the content of β-carotene and total carotenoids in the yolks. The addition of astaxanthin oil extract at doses of 10, 20 and 30 mg/kg of feed increased the content of astaxanthin, β-carotene and total carotenoids in chicken egg yolks and increased the intensity of their colour to 12.8, 14.8 and 14.4 points on a 16-point colour scale YolkFanTM. To obtain chicken table eggs with a given colour of the yolks, it is advisable to use the addition of astaxanthin oil extract in doses from 10 to 20 mg/kg of feed for 30 days. The results of the research can be used to develop a technology for the production of functional table eggs enriched with carotenoids of natural origin with an attractive colour for consumers.

Nowadays ornithobacteriosis is widespread among industrial poultry in Ukraine and the world. The disease leads to significant economic losses. The large variation in the serotypes of the bacteria complicates the treatment of the disease. The study of microscopic changes that occur in organs during ornithobacteriosis will help to better understand the pathogenesis of the disease development. Ornithobacteriosis was diagnosed in clinically sick broiler chickens by bacteriological studies using Maldi Tof mass-spectrometry. As a result of the antibiotic sensitivity test, the pathogen was found to be sensitive to doxycycline, tilmicosin, rifampicin, cefazolin, amoxiclav and benzylpenicillin. Histological studies of internal organs – trachea, lungs, heart, kidneys, liver and spleen – were carried out. It was found that with spontaneous ornithobacteriosis of broiler chickens, the most expressive microscopic changes occur in the respiratory organs – the lungs and trachea and are characterized by a decrease in the lumen of the parabronchials due to edema of their walls and infiltration with lymphocytes, the absence of epithelium on the surface of the parabronchials, narrowing of the air capillaries of the parabronchial complexes, hemorrhages in the parenchyma of the parabronchial complexes, vasodilatation of the lung vessels and overflow of their blood vessels with blood cells, edema around the epithelium trachea, destruction of part of the tracheal mucosa epithelial cells, edema of its submucosa, expansion and overflow of blood vessels of the mucous membrane with blood cells. In the spleen there was a uniform diffuse edema of the parenchyma and a decrease in the number of lymphocytes in the lymphoid follicles; in the kidneys – expansion and overflow of the stroma blood vessels, uneven edema of the glomeruli of one part of the renal corpuscles and destruction of the glomeruli of another, granular degeneration of the convoluted and straight tubules of the kidneys; in the liver – edema, hemorrhage, violation of the hepatic lobules’ structure, expansion of the hepatic veins, granular degeneration of hepatocytes or their destruction; in the heart – edema of the myocardial interstitium, muscle fibers’ granular dystrophy, fragmentation of muscle fibers as a result of their rupture. Histological research of ORT infected chickens will lead to a better understanding the mechanism of pathological changes at the microscopic level, which will facilitate the development of more effective methods of treatment and prevention of the disease.

Widespread use of surgical interventions in the abdomen of dogs determines the relevance of the study. The research tested the influence of therapeutic epidural blockade with 0.2% bupivacaine after surgical interventions on the background of potentiated local anaesthesia on the body of clinically healthy dogs undergoing ovariohysterectomy. In the control group postoperative analgesia was performed with the nonsteroidal anti-inflammatory drug rimadyl on the background of potentiated thiopental anaesthesia. Wound healing rates were determined in 10 animals of both control and experimental groups; blood counts and the level of inflammatory response were indicated in 5 animals of each group. The dynamics of reparative processes and complete wound healing in dogs of the experimental group occurred earlier than in animals of the control group, which confirmed the fact that the use of bupivacaine had a beneficial effect on tissue regeneration. The results of morphological and biochemical parameters of blood in animals of the experimental group manifested only an increase of leukocytes by 1.58 times, fibrinogen by 2.02 times, while in dogs of the control group the level of erythrocytes, haemoglobin and hematocrit decreased, leukocytes increased by 1.74 times, platelets decreased by 2.87 times and fibrinogen increased by 1.72 times. Among the stress response markers in the control group there was a 1.94 times increase in glucose level after surgery. In the experimental group there was a decrease in the intensity of the inflammatory reaction in dogs, accompanied by an increase of anti-inflammatory interleukin 4 (IL-4) only on the seventh day – 1.86 times, while in the control group the level of anti-inflammatory interleukin 1 receptor antagonist (IL-1RA) after three days increased by 2.30 times, after seven days – by 2.48 times, and the level of proinflammatory interleukin 6 (IL-6) after surgery increased by 2.57 times. It will be promising to conduct further research on the influence of therapeutic blockades with bupivacaine in animals in cases of various surgical interventions and pathological conditions, which will lead to faster recovery of animals and alleviate pathological processes.
Differential characters of fleas of the genus Ctenocephalides (Siphonaptera, Pulicidae) obtained from dogs

Published: June 2021

Fleas are the common name of the order Siphonaptera, obligate provisional nidiculous parasites of mammals and, to a lesser extent, birds, which can also feed on humans. Fleas can cause ctenocephalidosis of dogs and are carriers of many dangerous infectious and invasive diseases. Their ability to use humans as an alternative host determines the importance of these parasites in health care. Therefore, the aim of the work was to establish morphological and metric characters of adult male and female fleas of the species Ctenocephalides felis Bouche, 1835 and C. canis Curtis, 1826, isolated from domestic dogs for species identification. Morphological studies of fleas have shown that the differential features of C. felis and C. canis include the shape of the head and anterior-dorsal cuticular notch on the head. Notably, male fleas of both species have a more rounded forehead than female fleas. The metric parameters of adult fleas can be used as additional identification features, which will increase the efficiency of differential diagnosis of parasitic insects. We found differences in male fleas by 23 parameters, of which the value of 17 parameters were smaller in C. canis specimens. Males of C. felis were 9.1–21.1% larger in total body length, lengths of head and thorax, as well as lengths of mesothorax and metathorax. Differential features included size of the teeth of the main ctenidium and pronotal ctenidium: in C. felis males all eight teeth of the main ctenidium, located on the left side, were longer by 12.7–41.7%, and the first, seventh, eighth teeth were wider by 25.4–43.0% than in C. canis. In female fleas, differences were found for 24 metric parameters, of which the values of 20 parameters were also smaller in C. canis specimens. Females of C. felis were 12.1–22.2% larger in terms of total body length, head, breast, prothorax, mesothorax, and metathorax. All their teeth of the main ctenidium were longer by 5.6–40.6%, and the first, second, third, and eighth teeth were 18.1–48.9% wider than in females of C. canis. The obtained results add to the already existing data on morphometric features of adult fleas of C. felis and C. canis species, and will allow timely and accurate diagnosis of ctenocephalidosis in dogs caused by parasites of these species.

Production of high-quality and safe food products in the conditions of technogenic environmental pollution is a problem worldwide, especially in Ukraine. As a result of the disaster at the Chornobyl Atomic Power Plant, radioactive substances, including caesium-137, contaminated the soil not only in Ukraine, but in many other countries. Zhytomyr Oblast is the fifth largest oblast in Ukraine and one of the regions that were the most damaged by the accident. Furthermore, this territory is contaminated by the most toxic heavy metals – lead (Pb) and cadmium (Cd) that actively migrate in the biological system: soil→ plant → animal → production → human, intensely accumulating in the products of plant and animal origin. The complex ecological situation and broad spectrum of biological and toxic actions of 137Cs, Pb, Cd require a number of measures that would prevent transformation of radioactive elements and heavy metals in the organism of animals, increase animals` productivity and safety of the food products made in the conditions of the Ukrainian Polisia. Therefore, we aimed at substantiating the practicability of using silage-concentrate, silage-concentrate-root vegetable and silage-concentrate-hay types of diet for young cattle during fattening and determining the impact of accumulation of 137Сs, Pb and Cd in livestock products. To perform the studies, we formed three groups of young bulls of Ukrainian Black Pied cattle using the method of analogues with creating comfortable maintenance condition and organization of in-detail planned feeding. The diet was composed of fodders prepared in the conditions of radioactive contamination. The laboratory surveys indicated that the main sources of 137Cs ingress in the organism of the animals were roughages and various types of silages, and the sources of heavy metals Pb and Cd were hay of red clover and concentrated fodders. In the experimental studies, we determined absolute and average daily weight gains, expenditures of metabolic energy per 1 kg of weight increment, specific activity of 137Сs and concentrations of the heavy metals (Pb and Cd) in the biological system “fodder-animal-production” during feeding of bulls with various-type diets in the conditions of the III zone of radioactive pollution. It was confirmed that substituting maize silage and carbohydrate fodders increased the average daily gains in the live weight by 2.3–4.6%, decreased specific activity of 137Cs by 8.7–20.1%, the content of Pb by 36.2%, Cd by 34.1–66.7% in the longissimus at silage-concentrate-root vegetable and silage-concentrate-hay types of diet for bulls. Thus, use of silage-concentrate-root vegetable and silage-concentrate-hay types of diets compared with silage-concentrate feeding had a positive effect on their productivity and safety of the food production.

Modern feed additives based on natural plant components are increasingly used as an alternative to synthetic antibiotics in animal nutrition. Phytobiotics are natural plant components that are increasingly gaining demand for use in ready-to-eat animal feed and provide proper health and microflora of the body. A scientific and economic experiment was conducted in order to determine their effect on the productivity of young pigs. We composed three groups of analogues each comprising 12 individuals, which were formed in a 15-day equalization period. According to the results of the study on the use of a new feed factor protein-vitamin-mineral supplement Efiprot in the diets of young pigs, a positive effect was observed on increase in the average daily weight gain by 4.1% and 7.1% compared with the control group. There was also seen a better absorption of nutrients in the diet compared with the control indicator. During inclusions of essential oil in the diet of the pigs, we observed an increase in the digestibility of nutrients: in particular, the level of digestibility of dry and organic matter increased in the second and third experimental groups, as well as digestible protein and digestibility of crude fat was better in the first experimental group than in the control group. During the study, there was a tendency towards better breakdown of sparingly soluble carbohydrates under the action of feed additives compared with the control indicator. Thus, the use of protein-vitamin-mineral supplement during the rearing of young pigs not only increased the efficiency of their rearing, but also led to better digestion and maintenance of the microflora of the gastrointestinal tract.

One of the results of the Second World War was the presence of a large number of the Germans, Austrian, Romanian and other prisoners of war on the territory of the Soviet Union. Their  were actively used in the postwar reconstructions. The article is devoted to the analysis of personal histories of the former enemy soldiers who were kept in the USSR after 1945 and then they were convicted in the 1940's. The main sources are the materials of the Security Service of Ukraine in Dnipropetrovsk Oblast archives. The mentioned above archival materials show that, despite the prosecution, the final sentence for prisoners of war was the same and they had to spend 25 years in labor camps. Particular attention is paid to the cases of George Ionescu, Rudolf Petri, Paul Edgard, Joseph Lecker and Johann Pikanski. In 1945–1950 they were held in detention camps No. 315 or 460, which were located on the territory of Dnipropetrovsk region. Each of these persons chose their own surviving strategy in the camp – escape attempt, avoiding work, finding opportunities to obtain information about the outside world, honestly abiding by rules or  sabotage. However, despite the chosen way, the process of repatriation was delayed for all of them until the 1950s. Only after the «Thaw» («Vidlyhy») epoch and the amnesty laws passing, the prisoners got possibility to return to their homeland.

Authors: Dobrushina Maria
Published: June 2021

The peculiarities of the semantic structure of the lexical unit language policy in the framework of the nominative field of the concept LANGUAGE POLICY have been considered.The definition of the term «nominative field» has been given, the types of nominations have been specified, the stages of constructing the nominative field of the concept have been determined. It is stated that the nominative field of the concept contains both direct nominations of the concept and nominations of cognitive signs. It is established that one of the key stages of constructing a nominative field is conducting a component analysis of the concept. During the analysis of definitions their variety has been obtained from linguistic and non-linguistic Ukrainian, Russian and English sources. It is determined that, defining the phenomenon under study, researchers describe one and the same notion with the help of different definitions. Eight lexical-and-semantic variants have been identified that make up the semantic structure of the concept LANGUAGE POLICY. The semantic structure of the concept LANGUAGE POLICY has been found to be polysemantic, and all lexical-and-semantic variants complement each other. Within each lexical-and-semantic variant, its hierarchical structure has been established: the archiseme, the differential semes and the potential semes have been identified. The semantic structure of the lexical unit language policy has been presented in the form of ordered sets of semes – sememes.
LIFE LONG ENGLISH LANGUAGE LEARNING AND ITS ROLE IN FORMING MULTILINGUAL MIND: EUROPEAN EXPERIENCE
Authors: Yashkina Victoria
Published: June 2021

In the focus of attention in the article are challenges of multilingual education reflected through the prism of prominent European multilingual universities’ experience. Crucial issue considered is whether they aim to develop a multilingual and multicultural competence in all students or a considerable part of the student population, or whether they allow students to follow a monolingual programme in the context of a multilingual university environment. The higher demand for international mobility among students and staff is one more incentive to adapt the educational programme at least in part and open it to other target groups, supported by a more heterogeneous staff. It is common knowledge that many European universities have parallel programmes in English and native languages, which aim at separate student groups. At the same time there are those which integrate programmes and expect their students to follow at least part of their studies in both languages. The main difficulty for the latter is the case of how to prepare a shift in language of instruction. This is the problem all universities with different languages at undergraduate and master’s level have to face, and there is no easy solution. One step towards lessening tension is the «early start direction»: a renovation in views to primary school education. As far as the academy itself is concerned, the increasingly dominant role of English in research makes it necessary to add English as a language of instruction. Without English as a lingua franca there would be much less communication and mutual understanding amongst Europeans today.
SOME PECULIARITIES OF S. LEACOCK’S SHORT-STORY «THE MAN IN ASBESTOS: AN ALLEGORY OF THE FUTURE» TRANSLATION INTO UKRAINIAN
Authors: Volkova Maryna

The role of S. Leacock as a representative of English-Canadian literature and peculiarities of his creative works are given in the article. The peculiarities of the literary translation which aim is to reflect ideas, feelings transforming the author’s images with the help of another language material, the main features that make it different from a classical one were stated. The scholars who scrutinize the problems of a literary text translation in the contemporary linguistics was found out. The differences between the original text of S. Leacock’s short-story «The Man in Asbestos: an Allegory of the Future» and the text of translation and its translation by A. Yevsa were analyzed in the article. The translation can be called adequate as some change of content of the original text by the target language means did not impact into general perception of the short-story in its translation. The translator conveys the author’s ideas provoking reader’s reaction to the story. A. Yevsa preserved its content, the system of images and the author’s style, emotional atmosphere and plot identity of the original text and the choice of linguo-stylistic devices used in the original text. General peculiarities of the translation into Ukrainian, main grammar and lexical transformations used by A. Yevsa were marked, among which are generalization, concretization, compensation, semantic development and combination of sentences prevail.
WORDPLAY IN DICKENS’S NOVELS AND WAYS OF THEIR TRANSLATION
Authors: Panchenko Olena
Published: June 2021

The article deals with the general problem of wordplay and its translation. The relevance of the problem is accounted for by the powerful role of wordplay or puns in creating in special artistic atmosphere of any belle-letter sample and difficulties in its translating. The novels by Ch. Dickens have drawn attention of hundreds, if not thousands, researchers. A greater part of them pays attention to the literary side; the papers dealing with his language are quite versatile as well. But we have not yet met the comprehensive description and classification of Dickens’s puns. The aim of our paper is to classify cases of wordplay in the novels by Ch. Dickens and some possible ways of their translation. To achieve this aim we solved the following tasks: a) to choose a reliable definition of wordplay, or pun; b) to create a set of examples taken from Dickens’ novels and their translation into Russian and Ukrainian which are available at the site Gutenberg Project (https://www.gutenberg.org); c) to classify the puns; d) to analyze ways of their translation. The translation of puns is a really great problem and there exist different ways of solving it. Having analyzed Dickens’ puns and wordplay we can summarize that these ones can be subdivided into personal and common; alphabetical, morphemic and word; homonymic, patronymic and polysemantic. The correlation between puns in the original and translation can be described as their direct relation (pun – pun), asymmetric relation (pun – no pun; no pun – pun) and extralinguistic additions. The prospects of our investigation are connected with the study of Dickens’ art of creating individual manner of speech.
