The economic effect of using biological diesel oil on railway transport [PDF]

, 2008
The tests performed by the authors have shown that diesel locomotive engines efficiently operate using a mixture of diesel oil and about 40% of rapeseed oil methyl ester (RME) while their ecological and economical parameters do not differ much from those

Biological Electron Transport Systems [PDF]

Proceedings of the National Academy of Sciences, 1970
The solid-state electrical conductivities of a number of ferredoxin model compounds are reported. For one of these compounds, (KFeS 2 ) n , an electron transfer rate for a 25 Å unit is shown to be at least 1 ×

Cadmium transport in sediments by tubificid bioturbation: An assessment of model complexity [PDF]

, 2006
Biogeochemistry of metals in aquatic sediments is strongly influenced by bioturbation. To determine the effects of biological transport on cadmium distribution in freshwater sediments, a bioturbation model is explored that describes the conveyor-belt ...
