Help with graph units and interpretation

AI Thread Summary
The discussion focuses on confusion regarding the interpretation of graphs related to capacitance and conductivity measurements from a broadband dielectric spectrometer. Key points include the puzzling presence of negative capacitance in one graph and the identical units used on both Y axes, raising questions about potential labeling errors. The participant expresses frustration with existing literature not clarifying these issues. There is a suggestion that the graph's labeling may be incorrect, contributing to the misunderstanding. Overall, the conversation highlights the need for clearer explanations of the graph units and their implications in the research context.

Hello,

I have been doing research with a certain biological substance and its capacitance and conductivity. The following graphs are from a computer connected to a BDS (broadband dielectric spectrometer):

I understand the fundamental units, but Re(C'), Re(C''), Re(σ'), lm(σ'') do not make sense to me. How can capacitance be negative in one of the graphs? Why is there no difference between both axis in terms of fundamental units? Is it possible that the units are wrong? I have been looking at all the texts I have, but none of them are able to help.

Looks like a labelling error in the graph creation. Notice that the two Y axes are the same units.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
