Point taken. Clearly this one was over the hills and far away. I don't mind ... it's always good to try to push past the limits, because it is in that way that we find ourselves setting new limits. Thanks again, for your time :smile:

Thanks for the reply pbuk :smile: Apologies for certain omissions ... and thank you for your median equation. I simply totalled the population groups and divided by 2 (mimicking the method that is often quoted). The Data Set The data set population is * 1000, to match the 'State Count'...

Hello everyone :) I'm struggling to wrap my head around recalculating a data set based upon median. The data set represents a fixed distribution pattern of population to income group. There is no data available for 'population to income group' at differing medians, hence we accept the...

Following up on your request for a list of published studies, I have put together a short list. I've pulled key statements from each, to provide a rapid overview to go with the titles. The first four involve oral administration, and therefore directly pertinent to the question. The fifth...

Yes; but the buffering is not inherently stable - probably from the age of 50 onwards (or whenever it becomes unstable). Bicarbonate is produced by the kidneys as a buffer against excess acidity in the blood, and is capable of performing this task until the kidneys decline in function (and then...

Here's one that might be worth a read. http://cancerres.aacrjournals.org/content/76/6/1381 There are a number, but I've closed everything down ... time for zzzzz. I didn't spend any time studying the details. Primarily, I was looking for general published support for the assertion. ... it was...

I fell upon an article outlining the general health benefits of a balanced pH, and specific anti cancer benefits. ... both concepts are well supported in published studies. The article then went on to describe a protocol, whereby sodium bicarbonate is dissolved in liquefied honey. The principal...

Ha! Not this time :biggrin: I do provide general engineering knowledge - particularly specific tips for universal application. Here's one I put up two days ago that I did live. Putting it all on the line helps students believe in themselves :wink: So as you can see, the project is a small...

I do agree. The knowledge at our fingertips is... enabling. I struggle for words to describe this dramatic change that we have witnessed I make sure that I contribute... the engine rebuild is also being shared.

It's an offshoot from the turntable thread. I was tidying up all the mess (trying to move on) :biggrin: ... and I found this dual coil, with only two cables. I thought, before putting it away, I'll find out what it does. After some feedback, I figured it was safe to test on the window winder motor.

It is very possible that a windscreen wiper motor would be better. Of course, I am very happy with our project as it is... the difficulty is deciding when to stop learning. For the brain, it's no longer a question of the specific 'here & now'. ... it's more like "oh... so below a certain...

I may be confused, but... https://en.wikipedia.org/wiki/Electrical_ballast indicates that this is the purpose of electrical ballast. I noted a crossover between choke and ballast - choke ballast. This may be correct or incorrect. Perhaps if we knew why, what was happening to the current, as it...

I just tried it in series with a motor. The PSU puts out 19v DC no load. With the motor running, it drops to 7v. It can be dropped down to 4v and still run. With the coil in series - still 19v no load. With the motor ON the voltage drops to 4v but no sign of life from the motor. Therefore it...

Yes... specifically blue & red - reading 2.3 Ω This is what confused me. Only two connectors (each end of the windings). Almost no resistance. Yet cabled blue and red (traditionally +ve -ve). I looked up choke, but so far, enlightenment has not arrived. ...Ah... but electronic ballast...

What's the purpose of this dual coil? It has a blue and red cable. It stood alone, mounted (isolated) on the chassis of a PC PSU. It's in good condition, so I'm keeping it, but what can be achieved with it?
