General Science / Re: How to kill, both natural and medical, aerobic bacteria in the gut?

« on: 03/06/2023 07:34:43 »

Antibiotics. Proper strong stuff from hospitals. I have heard of doctors end up prescribing those dainty little bottles from the supermarket that are the gut bacteria stuff.

If you think that (UK) supermarkets sell antibiotics you are not well enough informed to be giving advice.

Antibiotics are noted for upsetting teh stomach- bloating is a fairly typical symptom.
PC is suggesting treating bloating with drugs likely to induce it.

It's as if he didn't understand this bit.

Please note: this is not seeking medical advice, just scientific evidence/opinion

Ahh thank goodness for the disclaimer.

The question asks for something to kill bacteria in the gut, the hospital grade antibiotics will do the job, hospital ergo not without very serious doctor prescribing. Killing the bacteria ergo no bacteria ergo needing something to replace the bacteria ergo little hospital pots of microbiotics or gut bacteria.

Ergo I wonder what happens if you drop antibiotics into bacteria culture is it like coke and mentos.?

General Science / How to kill, both natural and medical, aerobic bacteria in the gut?

« on: 01/06/2023 11:51:55 »

Hello

Is there a way, both natural and medical, to kill aerobic bacteria in the gut?

I think bloating is caused from these and I would like to know how to kill them. I know Rifaximin is killing some that cause ammonia.

Please note: this is not seeking medical advice, just scientific evidence/opinion

Thanks!

Geology, Palaeontology & Archaeology / Re: Is there enough lithium?

« on: 01/06/2023 10:16:30 »

Apparently, Lithium has no significant new sources in the whole universe...
- Lithium was produced in the early universe, making up 10^-9 of matter from the Big Bang
- When Lithium finds its way into the core of stars, it is rapidly fused into heavier elements (ie the amount is reducing)
- When stars fuse lighter elements, they "skip over" Lithium, so no new Lithium is being produced in stars

So, it is important to wisely use what Lithium we have (and recycle what we no longer use)...
- Lithium is great for mobile applications, due to its low density
- But for stationary power storage, other chemistries are becoming competitive, like flow batteries

The " Universal " part.
If a whole city agrees & accepts it, then it becomes a City moral standard.
Similarly...
State moral standard.
Country/Nation moral standard.
Continental moral standard.
Planetary moral standard.
Interplanetary, Galactic, Intergalactic, Clusterial, Interclusterial, Observable universe & then finally " Universal Moral Standard ".

You can expand the scope by space like that. You can also expand the scope by similarities.
Let's start by individual moral standards. For the sake of the argument, assume that it's the smallest unit of consciousness where morality can be applied.
It can be expanded to siblings moral standards. Then clan's, tribe, race, species, genus, phylum, base chemicals, and finally universal moral standard. However you divide them, they will converge if their scope is expanded enough.

New Theories / Re: Why is the sky blue?

« on: 31/05/2023 15:38:17 »

The light emitted by the Sun is red shifted by the Sun's gravitational field by a significantly larger factor than the Earth's gravitational field blue shifts it because the Sun is much more massive than the Earth. Despite this, the Sun's light still appears white from space. The degree of change in wavelength is incredibly small.

Besides, what Bored Chemist said about the sky being red at sunset also demonstrates that gravitational blue shift cannot be the reason behind the sky's color: the Earth's gravity doesn't change at sunset.

ChatGPT seems like a longwinded philosopher rather than someone who actually understands information theory. Try Wikipedia - the entry seems to have been written by folk who know what they are taking about.

Strictly, of course, a code is a string that identifies a longer string stored in the receiver, whereas a cipher simply substitutes one symbol at a time so that the decrypt contains the same number of bits or whatever as the encrypted string. Thus "BMBO" is a simple cipher for "ALAN", but "ALAN" is a code for "an old geezer in Cambridge with nothing better to do with his time".

The unexpected message will only contain information if the receiver has some preconception of what the sender means. Thus ALAN or even .-  .-..  .-  -. will probably denote at least "a British bloke" to many earthlings but conveys nothing at all to a Martian tree frog.

Why is Space temperature stuck at -270?C ?

It isn't. It's still falling, but being so close to zero already, it hasn't much further to go.

So why can't it go extremely low?

It's already extremely low.

is ' intesimally ' even a valid word?)

Interesting word, sort of combining 'infinitesimal' and 'intensely'.

Was the temp of the Observable universe ever between 21?C to 24?C?

1, it's the entire universe, not just the observable part. Yes, it was all those other temperatures along the way to where it is now.

Are Measurements lower than -273?C possible?

Zero K is as low as it gets. There are articles that claim some sort of negative energy and express it as lower than zero temperature, so you'd probably be able to google something that claims otherwise.

Ya i know, it's Absolute Zero, but i wanna know if We have instrumental capabilities to Measure lower temps or not?

Any instrument can display a negative number, but if nothing is actually colder than zero, it wouldn't be a measure of anything's temperature.

next im gonna inquire about BH temps, so be prepared.

See no-hair theorem. It says that BH has mass, charge, and angular momentum, and no other properties. Temperature isn't one of those.

I'm not sure if we can communicate with unicellular organisms about our common goals. But it's pretty clear that they have instincts to survive and reproduce, which can be reasonably thought as the products of evolutionary process.

More to the point, most of them regard us either as enemies or food. What moral right do we have to determine their goals, or to assume that they are the same as ours?

It comes from our expectation that we know better than them about how the universe works, and we can better predict and affect future conditions, which makes us better equipped to achieve the universal goal. It's like how parents treat their little children. When they have outgrown us, the situation would be reversed.

General Science / Re: Skiving

« on: 29/05/2023 21:03:16 »

The proportion of the Tool was huge, in comparison to the job/product.

It had a yellowish oily fluid in place of a milky white cutting fluid.

Anyways, i think the Thickness of the plates being cut is not allowing it to Curl.
(guessing)

See here:


Skiving.png (8.13 kB . 1717x656 - viewed 113 times)

In order for the shaving to separate, it must bend at A in order to make room for the tool, but before A it had to bend at B, and before B, C, etc. Hence the shaving curls, because once it has bent at the tip, there's nothing applying a force to straighten it again.

If you look at the video however, you'll see that the finished fin is less that half the length of material shaved off, so it must be being compressed, and I think it might be the deformation beyond it's elastic limit as it's compressed that's straightening it, but I'm not conviced I can see where the force to do that would come from either. The shaving is sliding over a smooth lubricated surface, after all.

And if it that's it, why doesn't all swarf come off the tool straight?

ps - Why is it a $64,000 question?

It's just a turn of phrase. It derives from an old 1960s TV contest in the USA where people answered questions with a prize that doubled each time. The final question was the $64,000 question.

COVID-19 / Re: What's included in protein-based vaccines?

« on: 29/05/2023 11:11:36 »

Every virus has a different set of proteins, so vaccines for different viruses need to emulate different proteins in order to create an effective immune response.
- But a useful target is the protein by which a virus enters the human (or animal) cell. Gum that up with antibodies, and the virus can't infect a cell - these are called neutralising antibodies.

Ultimately, the mRNA vaccines are also protein vaccines - they expose a protein to the immune system, which then targets that protein with antibodies.
- The difference is that the mRNA sequence provides the template from which the target protein is manufactured by ribosomes.

If you are talking about COVID specifically:

Like other coronaviruses, SARS-CoV-2 has four structural proteins, known as the S (spike), E (envelope), M (membrane), and N (nucleocapsid) proteins; the N protein holds the RNA genome, and the S, E, and M proteins together create the viral envelope.

The only proteins exposed to the immune system are S, E & M.
- Most existing vaccines target the Spike (S) protein, to create neutralising antibodies.
- Someone who has been infected will also develop antibodies to E & M proteins. These won't neutralise the virus, but they will draw the attention of the immune system to an infection.

Energy is a conserved quantity in newtonian mechanics, but interchangeable with mass (another newtonian conserved quantity)  in relativistic mechanics. Nothing more, nothing less.

School curricula tend to be written by educationalists, not teachers, and therefore serve only to confuse the student and put him off "difficult" subjects like physics. Fact is that physics is really dead easy because it is about what happens (dynamics) or doesn't happen (statics) - stuff you see in everyday life.  Quite unlike history (deciding which account of stuff you never experienced is less unreliable) languages (the grunts made by apes who look like us but live somewhere else) literature (many books of bad English written about a few lines of good English) or religion (you'd be prosecuted for selling any other product that doesn't work).

Complementary Medicine / The Benefits of Air Baths...

Are there any real benefits to "air baths"? Benjamin Franklin reportedly used to take them. He basically just sat around the house naked for a couple of hours. I assume he put a rob on if he had any guests. But is there any real medical benefit? Nudists are welcome to this discussion.
