[Stoves] RESEARCH PROPOSAL

[Gloria Chaonamwene]

Hi Crispin

Thanks a lot.  Your study seem to be similar to what I am trying to do.
These issues of stove performances what , I am starting to understand them
now and its of great advantage for me to be a member of this great network
and discussion group.  What kind of equipment did you use?  Is it  UCB, HOBO
and draeger tube for indoor air pollution or other types of equipment?  Is
it possible to forward to me a copy of a research proposal so that I don't
re invent the wheel or any kind of information.  I need to be guided in so
many areas. I am sure I will enjoy the mathematics around the study.  I
enjoy the discussions on calculations going around only that I don't follow
them, but now I will have to.

Once again thanks very much

Gloria
