Murat Abenovich Aitkhozhina - a specialist in the field of molecular biology and biochemistry, academician of the Academy of Sciences of the Kazakh SSR (1983), Doctor of Biological Sciences (1977), Professor (1980), winner of the Lenin Prize (1976), a disciple of Academician A. Spirin. Biography In 1962 he graduated from the Kazakh State University named after SM Kirov in 1965 - graduate of Moscow State University named after MV Lomonosov. In 1965-1967 he worked as a junior researcher in the years 1967-1969 as a senior research associate at the Institute of Botany of the Academy of Sciences of the Kazakh SSR. In 1969-1978 years - head of the laboratory, in the years 1978-1983 - Director of the Institute of Botany of the Academy of Sciences of the Kazakh SSR. In 1983-1987 years - Director of the Institute of Molecular Biology and Biochemistry, Academy of Sciences of the Kazakh SSR. In 1986-1987 - President of the Academy of Sciences of the Kazakh SSR.Contribution to science Aitkhozhina Murat was the founder of molecular biology and biotechnology in Kazakhstan. Aitkhozhina one of the first in the world of science conducted a comparative study of the protein synthesizing system in higher organisms, engaged in the search and study of physical and chemical properties informosom in plant cells in the group of Academician A. Spirin. Group opened informosom plant classes - free cytoplasmic, polysome-associated and nuclear, including RNA-binding proteins. In 1983 Aitkhozhina organized by the Institute of Molecular Biology and Biochemistry, Academy of Sciences of the Kazakh SSR. In 1987, it was organized by the Kazakh Agricultural Biotechnology Center, which works on the cellular and genetic engineering of plants.Murat Aitkhozhina the first to introduce a course in molecular biology and a number of special courses for students of biological faculty of Kazakh State University. Under the leadership of Aitkhozhina it was designed set of instruments for the automation of molecular biological experiments, which was protected by 15 copyright certificates and 16 patents in the leading countries. Awards Lenin Prize (1976) - for the series of works "Discovery informosom - a new class of intracellular particles." Listed in the "Golden Book of Honor of the Kazakh SSR" (1974). Gold Medal of the Soviet Peace Fund (1987). Order of Friendship of Peoples (1987).
Partial renewal or renewal of components comprises the intermediate renewal1 of
major or minor components - switches, crossings, worn rails, insulating rail-joints, etc.
- Day-to-day maintenance includes maintenance of desirable standards of all com-
ponents of railway track and alignment which can be done mechanically or manually.
(3) Day-to-day maintenance includes tamping, lining, patrolling and other tasks.
Complete renewal as well as earthworks and reballasting require both temporary speed re-
strictions (TSRs) and ’abnormal’ possession of the fine. Earthworks, reballasting and day-
to-day maintenance may require ‘abnormal’ possessions only, while partial renewal of
components requires, at the worst, a ‘normal’ possession.
(4) A ‘normal’ possession is one which requires no alteration to regular services. An
‘abnormal’ possession does require alterations, and sometimes it may take up to 50 hours
to carry out this work. Generally, a weekend ‘abnormal’ possession lasts some 15-20
hours.
Note: 1) intermediate renewal – средний ремонт.
