Results: The U5MR came down from 38.02‰ in ′80s to 36.04‰ in ′90s, while newborn mortality (NMR) from 17.71‰ to 13.82‰, infant mortality (IMR) from 28.24‰ to 25.84‰ respectively.
Since 20 century 80s', with the successful application of Activity-based Costing in advanced manufactory, people found it had the benefit to the corporations management.
Owing to the retardation of improving other factors which are important for better growth of crops, the recovery of fertilizer nitrogen by crops decreased rapidly over the past thirty years from 0.6-0.5 in the 1970's down to 0.4 in the 1980's and only 0.3-0.35 in the 1990's of last century.
The extinction probability, current and expected future diversity, breed contribution, marginal diversity and conservation potential of 20 yellow cattle breeds in China were calculated, and the maximum likelihood tree was constructed with Weitzman approach based on the investigation results in 1980's and standard genetic distances from 6 polymorphic blood protein loci.
Thunderstorm days were more in the south and less in the north,the period of 8-10 years was remarkable before the middle of the 1980s and the general trend of thunderstorm days was decreasing.
The results show that,on China's macroeconomic level,“returns effects”fluctuates from 30%to 80%,and the average returns rate in the 1990s is obviously lower than that in the 1980s.
In general, the trends in the levels of TC, TG and LDL-c were increasing and trends in the levels of HDL-c were decreasing in most age groups, especially, in the younger age group of Shanghai residents from 1980s to 1990s.
The isolation of these enzymes in highly purified states in the 1970s and 1980s strongly stimulated further studies of their structure, functions, and mechanisms of action.
Stages of the evolvement and development of the major directions of molecular biology in the 1950-1980's and its prehistory bracketing the 1920-1940's are considered against the backgrounds of the history of the Soviet science.
A very large sample plug was introduced hydrostatically into the capillary (65 cm × 50 μm i.d.; effective length of 35 cm) over 80 s at a height difference of 11 cm.
Types of mRNA analogs, model complexes of these analogs with 80S ribosomes, and methods for analysis of the ribosomal components (proteins and rRNA nucleotides) cross-linked with the mRNA analogs are reviewed.
If codon UUU is located at the E site, the pUUUGUU derivative with the photoactivatable group at the uracil residue modifies G-961 of 18S rRNA, which is for the first time found at the mRNA-binding center of 80S ribosomes.
In general, the trends in the levels of TC, TG and LDL-c were increasing and trends in the levels of HDL-c were decreasing in most age groups, especially, in the younger age group of Shanghai residents from 1980s to 1990s.

This review summarizes information published in the 1980s-1990s about anthropogenic pollution in Peter the Great Bay, the largest of the bays in the northwestern part of the Sea of Japan.
Regeneration of water streams that died away in the 1980s-1990s, and the formation of a new channel network in the lower part of Terek delta are recorded.
