  • The Curious Divide between Conservation Science and IA

    Since returning to academia, I have been struck by a particular disjuncture between the biodiversity sciences and IA practice in my country, Namibia. Having worked across Africa, my suspicion is that it probably applies to the entire continent, perhaps even broader. Allow me to expand. I had my wildlife scientist hat on a few weeks ago at a southern African symposium on wildlife tracking and ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...
