Whatever confidence he has inspired on policy matters derives from his pledges to leave the heavy lifting to his cabinet, which is staffed with several competent ministers.
Sapropelic coals are rich in liptinites (microscopic organic matter derived from waxy or resinous plant parts) and have high yields of volatile matter.
Concentrations of TOC with low δ13Corg values could be interpreted to represent a change in the proportion of organic matter derived from land plants versus oceans25,26.
This study compared estimates of fibre orientation dispersion in white matter derived from diffusion MRI to reference measures of dispersion obtained from polarized light imaging and histology.
We conclude that the displacement of organic matter derived from the lake is an important external source for the microbial processes in these soils at a landscape scale.
The addition of exogenous organic matter derived from organic wastes has been widely used to restore semiarid, degraded soils, favoring the development of plant cover.
This detrital peat had a high organic matter content (mean 88%), a δ13Corg value indicative of organic matter derived from C3 plants including mangroves (−28‰), and an unknown calcareous microfossil suggestive of a non-marine habitat in the sinkhole.
Meanwhile, another isotopic ratio, that between the light and heavy forms of carbon in organic matter derived from marine algae, reflects the amount of carbon dioxide in the atmosphere when the algae were alive.
The unorthodox subject matter, derived from a story by Nikolai Gogol and redolent of the writer's uniquely Russian brand of humor, may formerly have kept theaters at bay but no more.
Enhanced transport of terbuthylazine, and to a lesser extent, atrazine, throughout the irrigation season, is attributed to their transport as complexes with dissolved, colloidal and suspended organic matter derived from sludge degradation.
In addition, a good linear relationship was found between the temperature of maximum evolution of volatile matter derived from the DTG curve and the characteristic temperatures indicating the beginning, end and maximum value of the fluid stage of coal.
