Apparent Accumulated Nitrogen Fertilizer Recovery in Long-Term Wheat–Maize Cropping Systems in China
Agronomy, 2018 Recovery efficiency of nitrogen fertilizers has always been an important issue, especially for N fertilizer recommendation rate in cropping systems. Based on the equilibrium of N in the soil⁻plant system, apparent accumulated N fertilizer recovery (

The nitrogen legacy: emerging evidence of nitrogen accumulation in anthropogenic landscapes
Environmental Research Letters, 2016 Watershed and global-scale nitrogen (N) budgets indicate that the majority of the N surplus in anthropogenic landscapes does not reach the coastal oceans. While there is general consensus that this ‘missing’ N either exits the landscape via denitrification or is retained within watersheds as nitrate or organic N, the relative magnitudes of these pools ...

ROSA/LSTF test on nitrogen gas behavior during reflux condensation in PWR and RELAP5 code analyses
Mechanical Engineering Journal, 2018 We conducted an experiment to clarify nitrogen gas behavior at low pressures during reflux condensation in a pressurized water reactor (PWR) with the rig of safety assessment/large scale test facility (ROSA/LSTF) at Japan Atomic Energy Agency.

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020 The conducted studies show post-harvest residues of sowing/pea mixtures limit leaching of mineral nitrogen deeper into the soil profile compared to post-harvest residues of sowing peas, as they affect the yield and amount of nitrogen accumulated in ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Thermal Behaviour of Implanted Nitrogen and Accumulated Hydrogen in Titanium
, 1997 The influence of nitrogen ion implantation on the hydrogen accumulation in titanium was investigated as function of sample temperature and ion fluence. 150 keV nitrogen (15N) ions were implanted at different sample temperatures up to 700°C with fluences ...

Metabolome Analysis Reveals Betaine Lipids as Major Source for Triglyceride Formation, and the Accumulation of Sedoheptulose during Nitrogen-Starvation of Phaeodactylum tricornutum. [PDF]
PLoS ONE, 2016 Oleaginous microalgae are considered as a promising resource for the production of biofuels. Especially diatoms arouse interest as biofuel producers since they are most productive in carbon fixation and very flexible to environmental changes in the ...

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses
