Ordering and density amorphous phase of carbon-fiber polymer-matrix PTFE-composites
Статья научная
We studied the application of a mathematical model for calculating the X-ray density of a pure amorphous-crystalline polymer, taking into account the degree of ordering, crystallinity and deformation of a crystalline cell in the amorphous phase, to carbon-fiber PTFE-composites. By comparing the theoretical densities (based on the developed software) of PTFE+CF-composites system with the results of experimental densities and X-ray structural parameters, it was shown that the degree of ordering and density of the amorphous phase of the polymer-matrix PTFE-composites linearly decrease as the content of the carbon-fiber increases. The change in the degree of ordering of the amorphous phase when filler application can be considered as one of the mechanisms of formation of supramolecular structure of composite materials on the basis of amorphous-crystalline polymers.

Discusses the impact of dispersed filler in the form of microcrystalline graphite (MG) on the formation of the supramolecular structure of the amorphous-crystalline polymeric materials the binary system of PTFE + MG. The theoretically calculated and experimental values of the composites densities are compared. The theoretical model of densities calculation takes into account the degree of crystallinity and the degree of the polymer-matrix (PM) ordering, as well as the deformation of the crystal cell in the amorphous phase. The degree of ordering and density of PM PTFE-composites amorphous phase behave in a complex manner with increasing content of dispersed filler and in a different way than with fibrous filler in the form of carbon fiber (CF). Studies of dual systems of PTFE + MG and PTFE + CF have shown that the ordering presence the amorphous phase can be considered one of the formation factors of the composite materials supramolecular structure based on amorphous-crystalline polymers.

Organic agriculture in Turkey and the world
Статья научная
Organic agriculture is an alternative production system that supports soil structure, fertility and conservation by protecting the ecological balance, using biological control methods against diseases and pests; based on the sustainability of living life, aiming for the highest yield with the maximum use of natural energy resources. In this context, it covers a different production process from conventional agriculture. While intensive input applications in conventional agriculture aim for the highest yield, organic agriculture prioritizes sustainability. Sustainable agriculture is defined as an agricultural practice that protects soil, water and biodiversity while meeting food, energy and natural resource needs. To ensure that organic agriculture contributes to sustainability goals, organic regulations need to focus more on environmental and best practices. Increasing demands day by day have positively affected the sustainability of organic agriculture. The common feature of most of the definitions of organic agriculture is that the products should be produced in accordance with the basic standards and that every stage from the land to the table is regularly controlled. The fact that every stage of organic agriculture is audited and documented, and that the practices operate in accordance with legal procedures are other noteworthy elements. These legal procedures provide protection at many points. Organic agriculture is not only limited to safe food production to protect human health; it is also an agricultural and ecosystem management that is environmentally friendly, effective in reducing ecological pollution, protection of water resources, prevention of erosion, protection of biodiversity, agricultural sustainability and agricultural development.

Peacebuilding through proverbs (in the example of the proverbs in the Kyrgyz and Turkish languages)
Статья научная
Peace building and peace education through proverbs and sayings in the Kyrgyz and Turkish languages are described in this article. There is a discipline called peace education taught at schools and universities in many countries. This discipline isn’t taught in our country and it’s difficult to imagine our life without conflicts. Proverbs and sayings expressing peoples’ wisdom and spirit are among the most ancient human institutions as they tell a story taken from our life experience. With the help of proverbs and sayings we educate our generation to build peace that they could have good relationship with other persons, within groups and with people from other cultures. In the globalization period it’s important to teach people how to make inner peace, how to interact with others and avoid unnecessary aggression. This article aims at defining how inner peace is educated and how these cultures build peace with others in the example of proverbs. Peace building proverbs connected with peace, tolerance, patience, avoiding or resolving conflict are picked up from the Kyrgyz and Turkish languages and studied comparatively.

Peculiarities of deixis and anaphora in speech discourse
Статья научная
This article considers peculiarities of deixis and anaphora in speech discourse. The author of the article believes that the separation of deictic and anaphora relations as independent objects of research in linguistics is associated with the consideration of the problems of deixis as a category of general activity theory, communicative-functional, pragmatic and cognitive linguistics, and anaphora as a category of text/discourse linguistics, which provides its structural-syntactic and semantic coherence. This explains the transition from the study of the characteristics of syntactic anaphora, mainly pronouns, within the sentence/utterance to the consideration of text / discourse anaphora.
