The Study of Sorption of the Milk Ionized Calcium by Sodium Alginate

The possibility of regulation of defatted cow milk salt composition (fat content– 0,05 %) with the use of sodium alginate as a natural ion-exchanger was studied. Realization of the properties of sodium alginate as to the bounding of calcium ions allows receive the systems on the base of cow milk, stable in time and at the thermal processing. The studies established the influence of technological factors on the sorption of ionized calcium by the solution of complex-creator by sodium alginate. It was established, that the important factors that influence the process are the active acidity and conditions of the process, namely, the phased addition of sorbent that favors the equal speed of process and, as the result, the equal speed of sorption during the whole process. At the same time the study of influence of sorption area and temperature demonstrates that these factors are not determining ones in this process. It was established, that rationalization of parameters of ionized calcium sorption results in the raise of thermal stability of defatted cow milk and the systems on its base. Materials, given in the work, are the base for elaboration and introduction of technology of dessert production (ice-cream, creams, puddings, cocktails and so on), in which composition the colloid stability is provided at the joint use of milk and fruit-berry raw material that can be used in food industry

Концепт-архетип Христос: підґрунтя мікроконцептосфери Святки

У статті розглядається вербальне вираження концепту Христос у складі мікроконцептосфери Святки, що передбачає вилучення інформації про досліджуваний фрагмент концептуальної картини світу людини зі словників різних типів та етнографічних джерел (культурологічний аспект) і визначення особливостей його репрезентації в мові (семантичний аспект). (The article deals with the complex analysis of the concept Christ of the microconceptosphere Sviatki projected for studying the peculiarities of its reflection in the synchronistical and diachronic aspects, as well as for clarifying of the specific character of its reflection in the hierarchical system of the linguistic world-image. Keeping within the limits of the lingvoculturological approach of the linguistic conceptology, in the research the notions such as conceptosphere, concept, conceptual microfield were considered. In the structure of the microconceptosphere Sviatki 46 central concepts distributed to 10 conceptual microfields were distinguished. The appropriate field structure (nucleus, near-nucleus zone and periphery) of the microconceptosphere Sviatki was modeled and the hierarchical organization (superconcepts, presuperconcept, basic concepts, subconcepts) was presented. But the technique of the analysis of the lingvoculturological concepts suggested in this work consists of 3 stages: 1) formation of the nominative field of concept and definition of its nominative density; 2) separation and description of the structural elements of the concept; 3) modeling of its field structure. During the analysis of every concept the means of its linguistic expression, including their paradigmatic and derivational peculiarities were characterized. The research of the central concepts of the microconceptosphere Sviatki permitted to discover the specific character of the national mentality of the Ukrainians within the limits of this fragment of the linguistic world-image.

The results of an experimental study on the development of critical thinking of higher education institution students in the conditions of education organization in teams

The modern society expects that the university students will have the skills to work in ateam, professional competences, and ability to think critically about the surrounding. Thesubject of studying the processes of critical thinking education, finding a way out of difficultsituations and applying such skills in practice, is relevant and attracts the attention ofdomestic and foreign researchers. According to their view, the higher education institutionstudents should have the integrative skills, ability to work in a team, think critically andcreatively realize their ideas. Formation of critical thinking is the result of interactionbetween a teacher and a student, and is most fully manifested in the involvement of studentsin teamwork, where the process of active thinking is created through the special training,making exercises and carrying out trainings

This paper is devoted to a study of the characteristic features of the composition and structure of crude oils from terrigenous Devonian producing deposits in the Minnibaevskii section of the Romashkino and Pervomai fields. Using the SynOil program, we identified the features of the molecular weight distribution of n-paraffins, cyclohexanes, and monoalkylbenzenes associated with the formation and transformation conditions in the crude oil deposits

Formation of high-carbon abrasion-resistant surface layers when high-energy heating by high-frequency currents

The paper shows the possibility of carburization of low-carbon steel surface layers using high-frequency currents. The mathematical modeling of carburization using high-energy heating by high-frequency currents (HEH HFC) has been carried out, the temperature fields formed during the given processing have been calculated, as well as the structural changes in the surface layers have been simulated. The features of the structure formation in the surface layers of low-carbon steel after carburizing via HEH HFC have been determined by optical and scanning microscopy, which is confirmed by the computational models. The rational mode of fusion via HEH HFC has also been determined (power density of the source q[s]=(1.5...4.0)•10{8} W m{-2}, (the relative travel speed of parts V[p]=5 ... 100 mm /sec), with forming the compressive retained stresses in the surface layer ([sigma][RS]=-300...-400 MPa)
