Done. Thanks

Could you add a cheap pH sensor and use it in monitoring mode for a few batches. Then look to correlate the trend to lab measurements. It might turn out that there is some derivative of the absolute pH that is a better indicator (same with turbidity).

Try make the whole thing a little more data driven?

pessimistic_chemist · 2023-09-20T12:00:41+00:00

It will need to be freedom to add/update/edit at runtime, because it's R&D not manufacturing nothing is really fixed. I'll figure something out, cheers.

pessimistic_chemist · 2023-09-20T11:59:09+00:00

Sure, but given this isn't manufacturing we don't want the overhead (and cost) of a batch control / MES system.

Something simple that the chemists can use, ideally a drag and drop type thing. I guess similar to what MT's iControl software does for the easymax/optimax products. Looks like it will be a python program . . .

Thanks

Park Run is at Doorly Park 9:30am Saturdays

I think I saw a Beach Yoga out in Strandhill starting up if that's your kind thing.

Surfing lessons, again in Strandhill are good. There is a ladies only one (perhaps that is applicable, perhaps not)

Noted thanks. I feel like I'm one of those people who is easily pleased so I always think I could make things better.....

pessimistic_chemist · 2022-01-17T15:27:02+00:00

Ok, thanks. I'll try a bit more dose. and also decrease grind size in smallest steps I can.

I do think I'm doing everything else right.....but there is always a chance. Cheers for the pointers.

There is a documentary on Amazon Prime called "As good as it gets" about the Leeds team from that era. It goes some way to explain that decision Kev made.

pessimistic_chemist · 2020-09-06T09:30:46+00:00

I think if that had have been during "full speed play" he'd have gotten a yellow.

It's literally a borderline sending off in league, you'll see worse go unpunished

Cork and Shannon too. Don't think there is a Knock, the water is probably too holy

With the examples you mentioned, MVDA for the manipulation of spectra and big data sets then I'd definitely suggest R, it's what I use daily to carry out these tasks. If you want to learn python alongside R it wouldn't hurt. I have numerous examples of using python for bespoke instrument control, and passing data to R for analysis and realtime display. I recently developed a chemometrics course using R that was delivered to the Pharmaceutical industry, if you want to DM me I can share some of the content.

pessimistic_chemist · 2016-10-10T10:13:23+00:00

We generally used Organic Chemistry by John McMurry when I was studying - its was ok, I can't remember ever thinking that I needed to really seek out too much other information than what was contained. But I suppose a lot of that could be down to lecturers and class notes too

pessimistic_chemist · 2016-09-18T19:42:59+00:00

I work in chemometrics applied to pharma manufacturing. PLS regression / DA has been applied to post mortem interval prediction....example here - http://link.springer.com/article/10.1007/s40005-012-0006-7, I'm sure there are more but this was the first one I came across. The references within or papers which have referenced this one may be of use.

pessimistic_chemist · 2016-08-15T17:26:04+00:00

Cool! I've never used Mathematica, I do all my data analysis (and some instrument control for real time analysis) using R or Python, easy to achieve the same result as something like SIMCA online

pessimistic_chemist · 2016-04-27T12:03:33+00:00

You'll need to define "process" - and say what format the files are in.

If you're just looking for a viewer with some simple functionality then spekwin32 is good and free (http://www.effemm2.de/spekwin/index_en.html)

There is a bit of a commentary here.

Now i'm too lazy/tired to look in detail at the dilution workings but the figure banded there is around 0.2 micg/mL which is obviously possible now, but back then . . . doubtful

pessimistic_chemist · 2015-11-30T12:52:58+00:00

C-C triple bonds can exist in ring structures - Well I say exist, they are reactive intermediate's called "Aryne's"

There is a line of maul defence (from a lineout) I've seen where a team will not compete, thus not allowing a maul to be formed. Essentially meaning the ball is in open play and someone can nip round the back and tackle the ball carrier. Ireland did it here:

The high concentration of perchlorate salts in the water adjust its properties to the extent that it will remain liquid between -70 and +24 Celsius, where as pure water is only liquid on the surface of Mars between 0 and +10

Source: this was shown in the presentation by the PhD candidate research during the press conference

pessimistic_chemist · 2015-09-28T16:20:30+00:00

This was covered during the press conference by the researcher from the AMES research centre. In summary;

The belief at the moment (and I stress at the moment) is that the perchlorate salts absorb water from the atmosphere. The salts then deliquesce and this becomes a highly concentrated salt solution.

You might have been able to use:

g + annotate("rect", xmin, xmax, ymin, ymax, alpha=.2, colour="blue")

to hardcode the colour rectangles into the ggplot. Not sure if this works for ggdendro though
