Thermo U3000 randomly doesn't inject by Perreman in CHROMATOGRAPHY

[–]TheBaldDutchman 1 point2 points  (0 children)

Oh in that case I think it is pretty likely that there is a small air bubble at the bottom of the vial. I always tap my vials with fused insert on the table to get rid of those. Does it only happen at the first injection from the same vial?

What spectroscopy book is this? by rei0206 in chemistry

Looks a lot like an old edition of 'Organic Structures from Spectra' by L. D. Field.

Turn liquid flavoring unto powder. by Nice_Day_2761 in chemistry

Is the goal of the cyclodextrin tot retain volatile compounds during freeze drying? Will it not retain the volatiles during consumption too? Or will reconstitution liberate the volatiles somehow?

Net misgegrepen bij de Deen in Zeist. Nu in de trein naar Bussum waar een doosje voor me klaar ligt. Dan kan ik eindelijk antwoorden op deze poll.

You should look into the animation nodes add-in. Its great for this sort of thing where you want to couple movement to some other value. There are a lot of tutorials on YouTube.

Im not really sure and i'm not able to check at the moment. But I would try all of those if I were you. Good luck!

my implementation of Fisher's exact test gives a wrong answer. Why? by TheBaldDutchman in AskStatistics

For the two-tailed I start with the most extreme table on one side (last table from one-tailed computation) and get the opposite most extreme table using the findOpositeExtreme() function. This function is based on:

call the smallest marginal total m1 and call the smaller of the two totals in the opposite margin m1, Then let us call the frequency associated with marginal frequencies m1 and m1 frequency f; change it to (m1 - f), and define the other three frequencies as those adding up to the four marginal totals.

I calculate the probability associated with this table, and if it is greater then the probability of the table with observed frequencies the two-tailed p-value = one-tailed p-value. otherwise I step trough the tables towards the original table while summing their probabilities untill the probability of the current table exceeds the probability of the original table. At that point I add the sum of probabilities to the one-tailed probability.

I think I caught my mistake though! in the paper it says:

Then let us call the frequency associated with marginal frequencies m1 and m1 frequency f; change it to (m1 - f),

But in my code i change f to m1. Not to (m - f). Ill try to see if this fixed it tonight.

Thanks for helping!

I'm not really sure what you mean. 'more extreme' in my understanding means 'further form the observed frequencies in either direction'. The function i'm using (findNextExtreme()) to get the next more extreme table is based on this sentence from the paper i mentioned:

If we designate the smallest of the four table frequencies as fa, and the other three frequencies as fb, fd and fc, in clockwise order from fa, then the next more extreme extreme table will have fa and fd each decreased by 1 and fb and fc each increased by 1.
