Numerous other factors affect the exchange of carbon-containing compounds between the tundra and the atmosphere.
Biogeochemistry deals chiefly with the cyclic flows of individual elements and their compounds between living and nonliving systems.
Rather than competing, the two types of bacteria have a mutually beneficial relationship -- they recycle sulfur compounds between them, in the process providing the worm with organic carbon and consuming some of the products of its metabolism.
Modern geochemical research also includes the study of chemical transformations of biological materials in rocks and the cyclic flow of individual elements (and their compounds) between living and nonliving systems.
To do this compounds between 2.8 and 3.3 were predicted as 3.31 and compounds between 3.31 and 3.7 as 3.71.
There was a significant difference in the average average relative content of the two compounds between the two varieties.
Paired t-test showed significant differences (p < 0.01) in total phenolic and flavonoid compounds between arnica and wormwood extracts.
Comparative study of phenol compounds between fresh and disposal OMW shows a significant difference in the concentration values (p = 0.023).
The nature of the changes is affected by the distribution of compounds between classes in the dataset and predicting performance.
A series of novel hybrid compounds between benzofuran and N-aryl piperazine have been designed and prepared.
The distribution of compounds between blood and brain is a very important consideration for new candidate drug molecules.
