Comparison of indices for the prediction of nitrogen mineralization after destruction of managed grassland [PDF]

open access: yes, 2010
Intensively managed grasslands are occasionally chemically killed with herbicide and ploughed in order to grow an arable crop. After this management, large N mineralization rates with large losses to the environment are commonly observed.

Deficiency of annexins A5 and A6 induces complex changes in the transcriptome of growth plate cartilage but does not inhibit the induction of mineralization [PDF]

open access: yes, 2009
Initiation of mineralization during endochondral ossification is a multistep process and has been assumed to correlate with specific interactions of annexins A5 and A6 and collagens.

Estimating annual soil carbon loss in agricultural peatland soils using a nitrogen budget approach. [PDF]

open access: yes, 2015
Around the world, peatland degradation and soil subsidence is occurring where these soils have been converted to agriculture. Since initial drainage in the mid-1800s, continuous farming of such soils in the California Sacramento-San Joaquin Delta (the ...

Bmp induces osteoblast differentiation through both Smad4 and mTORC1 signaling [PDF]

open access: yes, 2017
The bone morphogenetic protein (Bmp) family of secreted molecules has been extensively studied in the context of osteoblast differentiation. However, the intracellular signaling cascades that mediate the osteoblastogenic function of Bmp have not been ...

OIL YIELD AND BULK GEOCHEMICAL PARAMETERS OF OIL SHALES FROM THE SONGLIAO AND HUADIAN BASINS, CHINA: A GRADE CLASSIFICATION APPROACH; pp. 402–418 [PDF]

open access: yesOil Shale, 2013
Oil shale evaluation is based on oil yield by low-temperature carbonization, which is an extremely complex process. The TOC, semi-coke content, gas loss, bulk density, S2 and HI correlate well with oil yield.
