    Can glucose combine with sodium bicarbonate?

    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...

    Can glucose combine with sodium bicarbonate?

    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...

    Can glucose combine with sodium bicarbonate?

    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...

    Can glucose combine with sodium bicarbonate?

    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...

    DC12V 12A car window motor - what spec for a 220V PSU?

    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...

    DC12V 12A car window motor - what spec for a 220V PSU?

    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.

    What's the purpose of this dual coil?

    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.

    DC12V 12A car window motor - what spec for a 220V PSU?

    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...

    What's the purpose of this dual coil?

    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...

    What's the purpose of this dual coil?

    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...

    What's the purpose of this dual coil?

    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?

    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?

    DC12V 12A car window motor - what spec for a 220V PSU?

    Here's one that will fit... found in the PC PSU. The alloy is 5mm thick, 70 x 70. Re the heat paste. I found it amazing that 30 year old paste around a stereo chip was still a paste under the skin. However, I'm glad to know that silicone grease works, as I have plenty of that.

    DC12V 12A car window motor - what spec for a 220V PSU?

    The Lamp Modification This went well. There is another gain in motor operation. I ran the motor down to 7 rpm - I think that is the lowest yet seen. The difference is marginal, but worthy More Motor Knowledge Here's the pre-amble explaining how the knowledge was acquired: Lamp The lamp shines...

    DC12V 12A car window motor - what spec for a 220V PSU?

    Actually.... it is hours. I hadn't timed it.... but it was switched off for hours. I looked down and thought hmmm that LED is still glowing. I flipped the switch to ON... the LED brightened and died. Development Pause - thoughts and observations With the product apparently developed - a pause...
