Evolution of the Bavarian dialect lexical system

The article deals with the specific features of the German language on the Bavarian dialect lexical level. The dialect is remarkable for its innovations and variety of linguistic forms on all levels of its system. The notion “Bavarian dialect” and its correlation with literary German language is being researched. The comparative analysis reveals the facts of deviation from the standards of the literary German language, especially in vocabulary and semantic

Comparative study of electrophoretic deposition of doped BaCeO3-based films on La2NiO4+δ and La1.7Ba0.3NiO4+δ cathode substrates

This paper presents the results of a comparative study of methods to prevent the loss of barium during the formation of thin-film proton-conducting electrolyte BaCe0.89Gd0.1Cu0.01O3-δ (BCGCuO) on La2NiO4+δ-based (LNO) cathode substrates by electrophoretic deposition (EPD). Three different methods of the BCGCuO film coating were considered: the formation of the BCGCuO electrolyte film without (1) and with a protective BaCeO3 (BCO) film (2) on the LNO electrode substrate and the formation of the BCGCuO electrolyte film on a modified La1.7Ba0.3NiO4+δ (LBNO) cathode substrate (3). After the cyclic EPD in six stages, the resulting BCGCuO film (6 μm) (1) on the LNO substrate was completely dense, but the scanning electron microscope (SEM) analysis revealed the absence of barium in the film caused by its intensive diffusion into the substrate and evaporation during the sintering. The BCO layer prevented the barium loss in the BCGCuO film (2); however, the protective film possessed a porous island structure, which resulted in the deterioration of the film's conductivity. The use of the modified LBNO cathode also effectively prevented the loss of barium in the BCGCuO film (3). A BCGCuO film whose conductivity behavior most closely resembled that of the compacts was obtained by using this method which has strong potential for practical applications in solid oxide fuel cell (SOFC) technology. © 2019 by the authors.Government Council on Grants, Russian FederationFunding: This research was funded by the Government of the Russian Federation (Agreement 02.A03.21.0006, Act 211)

Effect of ultrasonic treatment on the dissolution of milk solids during the reconstitution of skim milk powder

ArticleThe producing reconstituted milk products that retain the same sensory properties as those of raw milk products is of high interest to the food industry In the technology of producing reconstituted milk processing products, the most significant factor that determines the component transition degree and the usefulness of the product being produced is the recombination process. It determines the possibility of bringing the organoleptic characteristics of reconstituted milk to the properties of the genuine one. One promising method to improve the process of milk powder recombination is ultrasonic exposure. The aim of the present study is to improve the process of milk powder recombination using ultrasonic exposure. The results of the conducted studies show that the ultrasonic treatment eliminates the agglomerates of dried milk particles in water and provides more accessible interaction between the particles and water, and as a result, improves the recombination process. The application of ultrasonic treatment during the reconstitution of the skim milk powder improved the dissolution of milk solids, as evidenced by around a 75% reduction in the amount of centrifuged insoluble sediment. The mass fractions of protein and lactose have increased by 4.8 and 6.5%, respectively

T-lymphocytes of the 2nd type of the immune response and their role in enhancing inflammation during the professional activities of firefighters

T lymphocytes of the 2nd type of immune response contribute to the development and exacerbation of inflammation, mainly allergic. Increased inflammation with prolonged exposure to adverse factors during the work of firefighters can lead to the development of various diseases. Evaluation of the immunity of firefighters is important for the appointment of adequate treatment and prevention of infectious and allergic diseases. This paper aimed to analyze the indicators of immunity in employees of the state fire service of EMERCOM of Russia, depending on the age and intensity of the professional workload. The surveyed were men (n = 79), mean age 31 years, work experience from 1 to 22 years, with different workload intensity. In peripheral blood, flow cytometry (Navios, FC 500, Beckman Coulter) was used to evaluate subpopulations of monocytes, the relative number of T lymphocytes of the 2nd type of immune response CD3+CD294+. The concentration of total immunoglobulin E (Immulite) was determined. From nasal secretions, the content of secretory immunoglobulin A (Vector Best) was evaluated (n = 30). Statistical processing of the results was performed using the Statistica 12.0 package (StatSoft). An increase in the number of CD3+CD294+ cells was observed in 16.5%. A direct correlation was found between the number of T lymphocytes 2 and the age of the examined persons (р < 0.05). In the group of firefighters with a more intense workload, an increase in the number of CD3+CD294+ cells were 5 times higher (р < 0.05). Among patients who had any disease of the respiratory tract, an increase in this population was observed statistically significantly more often – in 26% of cases versus 11.5%. A strong direct correlation was found between the number of T lymphocytes 2 and the duration of smoking experience (р < 0.05). A direct correlation was established between the number of T lymphocytes 2 and the concentration of total IgE (р < 0.05). A decrease in secretory IgA in the secret from the nasal passages was observed in 23% of firefighters, in 13% of the examined, the indicator went beyond the upper limit of the reference interval. Significantly more often revealed the deviation of this indicator from the reference values in firefighters with a high workload. An increase in the subpopulation of classical monocytes was established in the group of those examined with a high number of CD3+CD294+ cells (p < 0.05). Thus, with an increase in the professional workload of firefighters in unfavorable conditions of service, inhibition of protection to infection and aggravation of damage to the respiratory tract with an increase in the 2nd type of immune response are noted. Evaluation of the number of type 2 T lymphocytes in peripheral blood will reveal a predisposition to the T2 profile of immune inflammation, which will contribute to a personalized approach to patient management

FEATURES OF IMMUNE RESPONSE AND BASOPHIL ACTIVATION IN CHILDREN WITH CHRONIC URTICARIA

Some features of peripheral bood basophil activation were studied in children with different types of chronic urticaria, in order to specify the sustaining mechanisms of chronic urticaria. This study presents comparative data concerning spontaneous basophil activation, IgE level and Th2 helper cells. We observed forty-seven children with chronic urticaria, seventy children with exacerbated atopic dermatitis with different disease severity, fifteen healthy children without signs of allergy, or pseudo-allergy. High degree of the basophil activation was detected in children with exacerbation of atopic dermatitis (a comparison group), which was different from the groups of healthy children and patients with chronic urticaria. Spontaneous basophile activation was higher in children with chronic urticaria than in healthy children, as influenced by immune and non-immune pathogenetic factors of the disease. A positive pairwise correlation was shown between total IgE level, and Th2 helper cell numbers in peripheral blood in patients with chronic urticaria, thus confirming a Th2 immune shift. The results obtained contribute to our understanding of immune pathology in chronic urticaria

Mathematical model of elastic ribbed shell dynamics interaction with viscous liquid under vibration

The mechanical model of the system, formed by two surfaces of the coaxial cylindrical shells interacting with viscous incompressible liquid between them under vibration, is considered. The outer shell is geometrically irregular, and inner one is an absolutely rigid cylinder. The mathematical model of this system, consisting of differential equations in partial derivatives for describing dynamics of viscous incompressible liquid and an elastic ribbed shell together with boundary conditions is constructed. The expressions for amplitude frequency characteristics of outer geometrically irregular shell are discovered

Factors of successful diversification for machine-building enterprises

The relevance of the study is due to the need to diversify production in order to increase competitiveness and strengthen the economic sustainability of enterprises. Increasing the output of high-tech civil and dual-use products by enterprises of the military-industrial complex as part of the conversion is complicated by the lack of enterprises work experience in the market. Conversion of defense industry enterprises is an important and promising task, the solution of which is connected with the future of defense industry enterprises, the development of import substitution, the expansion of high-tech exports. The purpose of the study is to analyze the world experience of conversion, to study existing approaches to solving conversion implementation problems, creating a system of conversion success factors, monitoring the effect of external and internal conversion implementation factors, identifying actual problems of this process. The author's approach to solving conversion problems consists of identifying external and internal conversion success factors and combining them into a single system for the interaction between the state and defense enterprises. The study of the implementation of the indicated factors showed the degree of their development, as well as the directions that will contribute to the development of diversification. © Published under licence by IOP Publishing Ltd
