Topicality and demand of the theme of dissertation. One of the actual problems of modern physical chemistry and macromolecular chemistry is the study on the development of the fundamentals of synthesis of functional polymers with ion-exchange and complexing properties.
Anion exchange and complexing compounds based fibrous materials have a high specific surface area, which provides a high possibility of sorption and desorption processes. They arc especially effective in removing toxic substances, even at very low content of the latter from the air and water pollution. Of particular interest is the acrylic fiber "Nitron", which is produced by JSC "Navoiazot" (Uzbekistan).
In the Academy of Sciences of the Republic of Uzbekistan, Tashkent Institute of Textile and Light Industry conducted research on the development of fibrous ion exchange materials based on acrylic fiber "Nitron" but they have not been brought to its logical end. In addition, when these studies neglected the study of the physicochemical aspects of the preparation of these materials.
In developing the fundamentals of ion exchange materials obtaining a lot of attention paid to the study of physical and chemical aspects of the synthesis and properties of these high-molecular compounds. These studies due to the fact that they allow you to adjust the processes of synthesis and, therefore, necessary to obtain polymers with required composition and with complex specific properties.
As noted above, to date, no attention was paid to the study of the physicochemical foundations of anion exchangers and polycomplcxons, due to applied research conducted to date in this field of research. In this regard, the study of physical and chemical principles of bases of creation, and the properties of anion exchangers and polycomplcxons based on acrylic fiber "Nitron" arc actual both from a theoretical and practical point of view.
Demand perform of the dissertation is characterized by the fact that modern worldwide technology for extraction of non-ferrous and precious metals can not be realized without the use of ion-exchange materials. These techniques use mostly granular sorbents, while fibrous sorbents comprise just 2-3 % of the ion exchange materials used . Using technology employing ion exchange material from algae and natural brine deposits of oil and gas recovered to 90% of iodine and bromine, lodinc-containing sorbents arc used for disinfection of drinking water from microorganisms and extraction of mercury from wastewater and gas emissions. They can be used for concentrating the processing solutions and biologically active substances in the preparation of catalyst systems nanoparticles metals. It should also be noted that Uzbekistan hitherto not been established as industrial manufacture granular and fibrous sorbents, although such polymers arc widely used in industry.
The purpose of this study is to identify the physico- chemical characteristics of the formation and properties of anion exchangers polycomplcxons based on acrylic fiber " Nitron ".
Scientific novelty of disscrtational research consists in the following:
in the first time studied the kinetics of the interaction of acrylic fiber "Nitron" with nitrogen-containing bases in aqueous and organic media;
shown that due to the high surface area fibers arc modifiable , the reaction rate depends on the concentration of the nitrile groups of the polymer being in the solid surface;
proved previously identified mechanism of the catalytic action of small amounts of hydroxylaminc on the process of modifying of fiber " Nitron " with nitrogen-containing bases;
in the first lime developed a method for producing anion exchangers branched structure by sequential treatment of acrylic fiber " Nitron " with cthylcncdiaminc and dichlorocthanc;
found that the interaction of PAN - fibers with hcxamcthylcnc- and ethylene diamines formed anion exchange fibrous materials having in its composition as a weakly basic and strongly basic functional groups ;
in the first time obtained new polycomplcxons with ampholytic properties by reacting maleic anhydride with amine -modified polyacrylonitrile fiber " Nitron " or by hydrolysis of residual of the nitrile groups modified with diamines of acrylic fiber "Nitron";
established values of the thermodynamic equilibrium constants of adsorption of ions Cr (VI), Си (II), halogens, Arsenazo (III) by synthesized anion exchangers and polycomplcxons and alteration in thermodynamic functions of the process testify to high sorption capacity of these ion-exchange materials with respect to the sorption ions;
Conclusion
1. Values degree reaction of the nitrile group and a nitrogenous base, the activation energy of the process shows that the process of modifying fiber " Nitron " nitrogen-containing bases subject to the usual regularities observed in homogeneous reactions. This effect is due to a high fiber surface area to be modified, allowing the reactants to facilitate access to the nitrile groups of the polymer. (Physical chemistry, High molecular compounds).
2. Kinetic studies of the reaction of acrylic fiber " Nitron " with diamine (hexamethylene and ethylenediamine) showed that the change of physical and chemical parameters of the modification process can be controlled sorption properties, chemical resistance and the strength of the anion exchangers due to network structure of the polymer. It has been established that this modification "Nitron" produces strongly basic anion character especially in organic media. Strongly basic anion exchangers possibility of obtaining a high sorption capacity with graft polycthylcnpolyaminc chain reactions revealed in fiber modification "Nitron " ethylenediamine in the presence of dichloroethane. (High molecular compounds, Physical chemistry ).
3. IR - spectroscopic and analytical determination of the formation of intermediate amidoxime groups in the polymer chains and free hydroxylaminc after substitution reaction proved previously proposed mechanism of the catalytic action of hydroxylaminc on the process of chemical modification of acrylic fiber " Nitron " nitrogen-containing bases . ( Physical Chemistry).
4. Developed conditions of synthesis polycomplcxons reacting maleic anhydride with modified by hcxamcthylcncdiaminc acrylic fiber "Nitron" and with of hydrolysis of residual nitrile groups modified by hcxamcthylcnc- and cthylcncdiamin of acrylic fibers . (High molecular compounds, Physical Chemistry).
5. Alkalinity obtained anion exchange resins depends on the nature of their functional groups. Strongly basic anion exchangers have in their composition cyclic amidine groups and they arc formed by the reaction of polyacrylonitrile fiber with a diamine. The specific surface area obtained fibrous sorbents exceeds by two orders of known surface area granular ion exchange resins, and their crosslinking rate is up to 100 nodes per macromolecule polymer. ( Physical Chemistry )
6. Kinetics and thermodynamics of the sorption of various inorganic and organic ions obtained polycomplcxons sorbents showed that ions of Cr (VI), Arsenazo (111) can be sorbed strongly basic anion exchangers only, and the process of sorption of copper (II) with polycomplcxons occurs not only due to the ion exchange, but also due to chelation. ( Physical Chemistry ).
7. Developed the conditions obtaining bromide complexes of polymers and kinetics, thermodynamics of the sorption halogen anion in synthesized materials was studied. It is shown that the lower the stability of the ion [Bn]’ for ion [J3]'than the ability to form such molecular chlorine ions leads to the fact that almost no molecular chlorine is adsorption, and molecular bromine is absorbed to a lesser extent than the molecular iodine. (Physical Chemistry ).
8. Combined developed iodinated anion exchange materials based on acrylic fiber " Nitron " and chitosan. Insertion of the iodinc-containing chitosan materials, leads to an increase of absorbent capacity. Combined antibacterial dressings have a pronounced anti-inflammatory and antibacterial effect, arc effective for the treatment of necrotic soft tissue diseases.

In the modern world, the principles of secular society dominate, on the one hand, and on the other, the process of the initial revival of religious consciousness, one of the ancient sources of popular culture. That is why religion has become a social institution on the agenda of many issues related to the role and status of modern society. Issues such as secularism, which implies the free, independent and independent activity of the spheres of public life. In this sense, this article is devoted to the analysis of this complex and controversial social process and its relevance. In the article, the term “secularization” occurs in terms of history and logic: the linguistic meaning of a word, its comparative and critical analysis of its definitions by various authors. At the same time, the objective and subjective factors behind the secularization process were uncovered. Specific examples of the sociocultural life of the West and the East are studied in detail and the content of the term "secularization" is defined. Particular attention is paid to the analysis of the views of modern philosophers on this issue, the analysis of theoretical views proposed by various academic schools. General and specific aspects of the description and approach are highlighted, the author’s own views on them are described and definitions of the concept of “secularization” are developed. Based on recent studies, general theoretical conclusions are given. As it is known, the secularization paradigms in the modern world are gradually changing. In this sense, secularization is not a feature of all societies. It should be noted that in the process of change, religious issues are at the center of public debate and, in some cases, at the center of controversy. However, secularization remains the core of the modern world, although religion is likely to occupy a huge space. Based on the above analysis, we can say that the processes of secularization are not based on a specific standard in different societies, and in each society there is a certain limit. Based on historical analysis, modern definition and description, secularization is a complex social process associated with the role of religion in society, and can be replaced by changing the order of religious traditions based on rational principles based on the principle of secularism.
Distillation and rectification processes are common in the chemical, petrochemical, and food industries. All these processes are complex and very energy-intensive. Since the rectification process directly affects the quality of the final product, the problem of energy efficiency and resource saving remains relevant. The main tasks in solving this problem are mathematical modeling of the technological process, optimization of the design and technological parameters of the process based on its modernization. A special place in solving this problem is given to process management. This is explained by the nonlinearity and multiplicity of the process, nonstationarity of behavior and the influence of various disturbing influences on the process.

The concurrent mixed-methods research design specifically the concurrent triangulation design was adopted for the study. Questionnaire and an interview guide were the instruments used for the study. The questionnaire consisted of both close and open ended questions for lecturers and post graduate students and interview guide for university administrators (HODs). The sample population for the study was made up of 1,915 lecturers, and 40 administrators (HODs) from the universities of Buea, Yaounde II, Douala, Bamenda, Yaounde I, Dschang, Maroua and Ngaoundere. The purposive and stratified sampling techniques was adopted for the study. Data from close ended questions was analysed using SPSS 23.0, with the aid of descriptive and inferential statistical tools while open ended questions were analysed thematically. The Spearman’s rho was used to test the research hypotheses formulated in the study. Majority of the lecturers (86.4%) agreed that there is a need for change in administrative policy to enhance relevance of Higher Education and a majority of the lecturers (71.3%) equally agreed that there is a need for change in administrative skills to enhance relevance of Higher Education. Hypothetically, there is a significant, positive and moderate relationship between administrative change and the enhancement of relevance in state Universities (R- value 0.207**, p-value < 0.001 < 0.05). Therefore, it was generally recommended that, for the enhancement of relevance in state higher education system in Cameroon orientation services should be organized before admission to enable student understand and make correct chooses. Specifically, in line with change in administrative policy most administrative posts should be elective for a given term of office in order to enable efficiency. Elective positions for HOD, Deans, Directors, Registrar and Vice Chancellors and in line with change in administrative skills, there should be innovation at the level of the administration by bringing in competent personal who will bring about the desired change to better enhance the relevant of HE.

In the contemporary world, people increasingly prefer alternative dispute resolution options to litigation in order to get more flexible process with quicker and cheaper results. One of the most recognizable forms of alternative dispute resolution is arbitration. The main benefits of arbitration are its neutrality of place, finality of process, flexibility, confidentiality, party autonomy, cost and time effectiveness, and finally its universally recognised process. However, lately arbitration has been criticizing for repeatedly extensions of deadlines by tribunals, recognitions of late evidences, acceptance of multiple amendments to a party’s written submissions and reschedule hearings by agreeing to last minute requests. This phenomenon is also known as due process paranoia. This article will emphasize the main reasons for due process from both respondents and arbitrators’ point of view. Moreover, the methods of improving the efficiency of arbitral proceedings and reducing cost and delay will be critically reviewed.

This article deals with topical issues related to the introduction of creative teaching methods into the educational process. This naturally necessitates changes in the methods and forms of organization of the learning process. The process of creativity includes, first of all, the discovery of something new: new objects, new knowledge, new problems, new methods for solving them.
Teaching and learning are two basic processes underlying the activity of students and teachers nowadays. The learning process puts both parties toward each other,what it teaches, and what it takes, the teacher and the student. Today training students to teach themselves, and their education, equipping them with the skills of independent work with the most advanced methods of conscious, sustainable, active, and creative learning takes great importance. The purpose of this topic is to know the importance of usage of all skills during a lesson hour. The teacher is free to use a variety of methods and strategies for teaching and learning to suit the needs of students in different classes. He combines these methods during the learning process and adapts according to the increasing development of linguistic competence and independence of student development, the consistency of this process. Teaching has at its center the method of communication, task-based methods, functional methods, and situations as real life, etc. These methods are realized through various strategies and techniques, according to language skills (listening, speaking, reading, writing). Teachers and students collaborate on the organization of teaching and learning. To facilitate teaching/learning, the teacher finds efficient ways to organize communication activities and provides and suggests source materials for students. In contemporary teaching, the teacher does not only play the role of teacher but also plays the role of supervisor. Together they establish cooperative relations in the process of learning.The teacher clarifies the students and takes their understanding of what happens in the classroom. This means clarifying the rules of the line of work and the responsibilities of students in the process of activities. The teacher suggests and provides the use of audiovisual means, electronic, and helps students to use various forms of information technology within and outside the classroom. It gives students the website in accordance with their age and educational requirements. In teaching, an hour should be applied to all four language skills strategies, but they escalate from level to level depending on the objectives. Setting the students in the spotlight makes the student participate actively in linguistic interaction, preparing them for a new phase of their education or being able to face the demands of the labor market.
From scientific research carried out in the world, we see that linguistics is in close contact with the neurological department of medicine and achieves effective results. Recently, a new field of science has emerged between psychology, neurology and linguistics, called neurolinguistics. The speech information process, that is, the process of transmitting information to each other and receiving information from each other through mutual speech, is considered the object of study of a number of sciences. In particular, this process is widely studied by the sciences of linguistics and psychology. Linguistics separates the language, which is the main means of communication between people, and the speech that arises in the process of direct communication-interaction, the internal structure, structural units, various occurrences of these structural units in the speech process, the transition from "internal structure" to "external structure" A number of issues have been studied , such as the main stages and the relationship of the two above structures, and this is considered one of the topical issues today
The article deals with the language on the Internet, the formation of the language of computer technology as a continuation of computational linguistics, its levels of development, especially the influence of language on the modeling of a new language for artifi-cial intelligence. The national corpus of the Uzbek language is of great importance in enhancing the international status of the Uzbek language. The work being done in the field of computer linguistics plays an important role in solving the existing problems in the Uzbek language. The article explores the need for building a national corpus, to learn the subtleties of words in the learning process, what to rely on in developing the ability to use it in speech; the importance of the Uzbek language to the science and the nation, There are well-grounded opinions about who can be the main clients and users of the Uzbek language. The main users of the corps are, of course, linguists who work in different fields. Reliable statistical information about a language of a certain period attracts literary scholars, histo rians, and other humanities. National language is also important in language teaching. Opinions were expressed about the technological process of creating a national corps. In particular, the technological process of the national corps takes into account: the creation of a vocabulary of the lexeme and word form based on the selected texts;
view the text for any unit of the received vocabulary; break a graphic
word into syllables and create syllables for repeating syllables; se-
lection of words; The simultaneous processing of unlimited files, the
creation of text files with external characters.
