Rate of removal of collagen and mineral from bone and cartilage
Metabolism, 1969Abstract The quantitative relationship between collagen and mineral dynamics in bone and costal cartilage has been studied. Young rats were injected simultaneously with both 14 C-proline and 85 Sr. The animals were sacrificed at intervals ranging from 1–20 days after injection.

The impact of herbivores on nitrogen mineralization rate: consequences for salt-marsh succession
Oecologia, 1999Soil net N-mineralization rate was measured along a successional gradient in salt-marsh sites that were grazed by vertebrate herbivores, and in 5-year-old exclosures from which the animals were excluded. Mineralization rate was significantly higher at ungrazed than at grazed sites.

Rates of CO2 Mineralization in Geological Carbon Storage
Accounts of Chemical Research, 2017Geologic carbon storage (GCS) involves capture and purification of CO2 at industrial emission sources, compression into a supercritical state, and subsequent injection into geologic formations. This process reverses the flow of carbon to the atmosphere with the intention of returning the carbon to long-term geologic storage. Models suggest that most of

Strain rate and mineral content in fracture models of bone
Journal of Orthopaedic Research, 1988AbstractI reanalysed data from my previous work to determine the extent to which a model for the loading‐rate dependence of the fracture of cortical bone, put forward by Carter and Caler, fits this independently derived data set. In particular, the extent to which the generality of the model is vitiated by its ignoring the effect of mineralisation on ...

Microdurimetric study of the mineralization rate of spongy bone in the dog
Anatomy and Embryology, 1976The microhardness-testing technique was applied to the study of the mineralization rate in the spongiosa of shaft bones of four dogs of various age. When bone tissue of the same “age” is tested the results indicate a higher mineralization degree of the metaphyseal than of the epiphyseal trabeculae; the degree of the mineralization of the latter is ...

TEMPERATURE DEPENDENCE OF NITROGEN MINERALIZATION RATE CONSTANT
Soil Science, 1995Experimental evidence suggests that nitrogen (N) mineralization proceeds differently under fluctuating temperature conditions than it does at constant temperature. Although N mineralization is believed to follow first-order kinetics, and the mineralization rate constant is believed to follow Q 10 temperature dependence, no effort has been made to use ...

Weak influences of climate and mineral supply rates on chemical erosion rates
2012Chemical weathering promotes regolith production, physical erosion, nutrient supply, and drawdown of atmospheric CO₂. Although mineral dissolution rates show dependences on temperature and moisture in theoretical models and laboratory experiments, effects of climate on chemical erosion rates in nature remain uncertain, in part because variations in ...

The measurement of rates of mineral loss with aging.
The Journal of laboratory and clinical medicine, 1976The photon absorption technique was used to measure bone mineral content in the radius repeatedly with time to determine the feasibility of using this method in studies on the rate of loss with aging. Two groups of postmenopausal women were followed, a younger group for an average of 3.74 years and an older group for an average of 2.37 years.

Dissolution rates of minerals and their relation to surface morphology
Geochimica et Cosmochimica Acta, 2002Abstract Experimentally observed dissolution rates of minerals in an aqueous solution are determined by surface reaction rates, mass transport by molecular diffusion through a diffusion boundary layer (DBL) and the morphology of the mineral’s surface.
