Development of Communication and Speech Skills of Students in the Process of Education

The article aims to study and diagnose school students with disabilities' levels of communication and speech skills development. Communication technologies in the process of forming communicative competence will contribute to the successful implementation of correctional work, if necessary, an individual or adapted educational program for students with disabilities. During the conduction of the study, the authors used the following types of methods: analysis, synthesis, modelling, observation, survey - statistical method analysis of the data allowed to differentiate levels of communication and speech skills development. The authors revealed the most effective forms and methods of work at the literature levels. The scientific-methodical and practical aspects of the application of communication technologies for the development of school students with disabilities' speech activities were generalized. In modern education, it has been substantiated that communication technologies are used as a means of communication skills formation and as a means of activation of the students' cognitive work. Based on the theoretical analysis of the investigated problem and the experimental work results, the authors have formulated the generalizing positions. It was concluded that the solution to the investigation of the school students with disabilities' speech activities development problem is possible at smart scientific and methodological use of communication technologies

The Study of Hematological Parameters of Animals in the Application of Enterosorbent Food Fiber

One of the most important issues is the study of healthy nutrition of the population of Kazakhstan. Proper nutrition provides growth, contributes to the prevention of diseases, increase efficiency and prolong life of people, while creating conditions for adequate adaptation to the environment. A large part of the population of Kazakhstan as a result of technological processing, the use of inferior in chemical composition of food raw materials, the influence of other causes, does not receive the necessary amount of essential components of food, which lead to illness, premature old age and shortened life. The situation is aggravated by the low cultural level of the population in terms of good nutrition and the lack of skills to lead a healthy lifestyle. The problem of quality and food safety, while food must have not only nutritional and physiological value, but also perform preventive functions

Charge transport mechanisms in inkjet-printed thin-film transistors based on two-dimensional materials

Printed electronics using inks based on graphene and other two-dimensional materials can be used to create large-scale, flexible and wearable devices. However, the complexity of ink formulations and the polycrystalline nature of the resulting thin films have made it difficult to examine charge transport in such devices. Here we report the charge transport mechanisms of surfactant- and solvent-free inkjet-printed thin-film devices based on few-layer graphene (semimetal), molybdenum disulfide (MoS2, semiconductor) and titanium carbide MXene (Ti3C2, metal) by investigating the temperature, gate and magnetic-field dependencies of their electrical conductivity. We find that charge transport in printed few-layer MXene and MoS2 devices is dominated by the intrinsic transport mechanism of the constituent flakes: MXene exhibits a weakly localized 2D metallic behaviour at any temperature, whereas MoS2 behaves as an insulator with a crossover from 3D Mott variable-range hopping to nearest-neighbour hopping around 200 K. Charge transport in printed few-layer graphene devices is dominated by the transport mechanism between different flakes, which exhibit 3D Mott variable-range hopping conduction at any temperature
