I'm having a hard time picturing cartels sweating chemical watchlists. Let's say it's true. It would realistically have to come from one source and have one consumer for it to remain a secret and it would be easily traceable in a way that diverted chemicals would not. Also unless it was an in-house operation I don't think there would be much of a price advantage. No, I think you're full of shit.

Hi

it's been a milltion years since i've done a CWE and there's one question i have in regards to the amoung of water to be used.

i understand that there is always going to be a little Acetaminophen in the final solution. however, codeine phosphate being as soluble in cold water, or just plain water, as it is i was wondering wether you could skip the whole freezing part of the procedure and instead use a small amount of water. where would potential problems be? i can imagine it would take a really long time as the water would have problems penetrating through the sludge of filter and Paracetamol. but apart from that why could this be a bad idea?

thanks for reading,
love Anon

if i wanted to start a small business where i test people's drugs for fent/pcp/meth/clam or whatever, what sort of reagents would i need to buy? I realize this is sort of an open ended question, i'm just sort of looking for general suggestions for pretty much any drug testing reagent that tests for something. there's pretty much nowhere that you can safely get your drugs tested around where i live & i really want to do what i can to help. i feel like i could save some lives with this.

especially looking for something that can detect if my jenk's been cut with dog pills

General method for determing max/min within a range? by Fucking Bellyburk - Thu, 28 Jun 2018 07:51:21 EST ID:rGLueGvy No.79150 Ignore Report Reply Quick Reply

Does anyone please know of a general way to determine if there's any local max and min *within a set range of X-coordinates*?

As we can see, there's a local max somwhere around -1 and a local min somwhere around 3 and none whatsoever in the range 1-2.

But how do I prove that there's no local max nor min in that range?

I'm looking for *local* max/min in trig-functions. I know that if the x-range is long enough, there will be *many* local max/min.

For instance this function has local max/min all over the place and repeats itself every 3600 x:

f(x) = sin x(sin (x/10))

I know there's a local max between x(1500) and x(1530). But how do I prove it by doing a f'(x) for only that range?

I think it still works the same way. Take derivative. Set equal to 0. Solve within your range. That's a lot of trig functions to fuckin deal with. Here's wolfram alpha's solutions:

https://www.wolframalpha.com/input/?i=d%2Fdx+sin(x)(sin(x%2F10))+%3D+0,+1500%3Cx%3C1530

Solutions are at the bottom. Hit the 'exact solutions' to see what kinda algebra is needed for that function. So obviously the way to do this is numerically. Look at the original function
https://www.wolframalpha.com/input/?i=sin(x)(sin(x%2F10)),+1500%3Cx%3C1530

Then look at the approximate solutions in the last page. You can see that the local maximum for that range is at:
x≈1522.1173171661698545755
For which the function returns: 0.987810970335936684937

Or, in one easy step: https://www.wolframalpha.com/input/?i=maximum+sin(x)(sin(x%2F10)),+1500%3Cx%3C1530

Maybe that's cheating, but fuck trying to analytically solve that.

the fact that youve posted that is further evidence of the genius of the idea to establish a /shill board. naw just kidding.

concerning the analytic component of the question, im kinda ashamed it took me this long to think of, you could take the derivative via product rule (not sure if another approach would deliver something more moldable) and then reason examine the zero points of the derivative and second derivative.

im a bit confused as to what the actual function is, should it - as mentioned before - be y= sin(x) sin(1/10), the derivative itself will be a sum of two periodic products, meaning youd have to evaluate cases where either both terms are zero or one term is the negative of the other. depending on the range the answer should be given in multiples of some fraction of pi (kirt, tex support when)

during my analytics classes giving a numeric answer was a telltale sign of misunderstanding the task

And should your task be to prove that the function has a local min/max on a given closed range you could simply show that the function is continous (as a composition of continous functions) and then a local min/max has to exist.

Hey guys.

So recently I've been interested in irreversible opiates.

A couple decades ago some scientists were able to do this by adding a hydrazine at the 6 ketone of oxymorphone, as well as at naltrexone/naloxone, making oxymorphazone and the corresponding nalts.

When tested, these hydrazines lasted extremely long, and blocked any further effect of opiates in animals. As well, radioactive versions of the drugs cold simply not be washed away from tissue expressing opiate receptors. Meaning these drugs were staying bound to the receptor.

Originally it was thought that oxymorphazone itself was doing the irreversible binding, but it was later determined that the oxymorphazone was joining up with itself spontaneously in solution, creating a dimer of sorts, oxymorphazine.

https://en.wikipedia.org/wiki/Oxymorphazone

There's no wiki on Oxymorphazine, but here's something similar: https://en.wikipedia.org/wiki/Oxymorphone-3-methoxynaltrexonazine

It's just two oxymorphones joined by a hydrazine at the 6 position of each.

Anyone have any suggestuons for literature, best practices, tools, etc? Whats a good aim for expanded education? Anyone transferred into a health science field from a different profession?
