I dive with GFs, I am thankful for them. They are rounding corners on my envelope. I want to push the envelope. I challenge the model.

Hi, welcome, yes but there is a caveat. The way the rate is behaving in the model is such that the rate (of change) is equal to a constant (the Half Time) multiplied by the difference in the concentrations between tissue and ambient. We are saying, or asking ourselves: should or could the...

I wasn't aware of the CRM approach so I looked it up, the analogy that hit me in the areas I am more familiar with professionally is in the enterprise world and in particular with the Soft Skills. In the Human Resources and Project Management and Troubleshooting spheres these are sometimes...

Very interesting article indeed! Thanks and it covers more the ground around the side of things related to how to approach the review of the incident and how to transfer that into lessons learnt as opposed to the application of an approach to help avoid an accident. From the post's title I was...

Well then you are missing out on a lot of fun and facts! ;-)

Agreed makes sense.

I agree fully makes sense.

I promised @tbone1004 above so here one more time, I am sorry I could not be clearer before, at my best right now I say: initial quantity (Q): 100 half-life (t1/2): 10 time (t): 10 quantity remains (Qt): 50 initial quantity (Q): 200 half-life (t1/2): 10 time (t): 10 quantity remains (Qt): 100...

Nope. I postulate it could factor in size to be even better. I like the model. I will go sleep now 'coz its late and during the weekend I hope to come up with another way to show how I understand half life and then you tell me. I am not afraid of being mistaken or proven wrong :-)

Yep. This is actually where the model is very strong.

Nope. This is what is happening in the model because in the model the compartments have no size. I don't know if this is happening in real life because the divers start with different absolute amounts of the same tissue and different absolute amounts of N2 and different distribution of the...

Yep!

Why you brush it off like this? You make a great contribution first. Or I misunderstood your last statement.

I think this is what motivated by question. I elaborate a little, so I need to add she took the on-line course first, I use the example of the compass because this is what triggered my thoughts as I was admiring her as she ploughed through the maths; whatever bearing minus 45 degrees or plus 90...

Technically this is the answer to my question, had I put as straight as it could be. Thanks.

She is 12.

I try to swim backwards with fins with vents Tech Fin DiveSystem and that appears to work just fine and better than with cressi sub rondine which are however longer so I can't say if that works better because of the vents.

Should you change fins consider they may weigh differently too and change your buoyancy. I see "softer" fins may be less efficient where there is current.

This is giving me something to think about, thanks. I don't know. Where and how is all this adipose tissue distributed in the body?
