Genetic mapping of natural variation in potassium concentrations in shoots of Arabidopsis thaliana [PDF]

open access: yes, 2006
Naturally-occurring variation in K+ concentrations between plant genotypes is potentially exploitable in a number of ways, including altering the relationship between K+ accumulation and growth, enhancing salinity resistance, or improving forage quality.

Reduced complexity models for water management and anode purge scheduling in DEA operation of PEMFCs [PDF]

open access: yes, 2010
In this work, the dynamic behavior of Fuel Cell operation under Dead-Ended Anode conditions is shown. A DEA can be fed with dry hydrogen, since water crossing through the membrane is sufficient to humidify the fuel.
