Yes, it appears that mathml support for \bot is not quite there. Interestingly, it works if there is a symbol before and one after so it's acting as if it is an operator. E.g. \alpha\bot\beta works fine. You could also use \perp instead although it's slanted and quite ugly (in my opinion). > (Why an an acedemic review request Word files? It should be > forbidden.)
