Concepts: Immunities, Resistances, Allergies?

Silicosis is related to inhaling stone powder in stone querries. Sand may be more sillica than stone powder. Since 1/3rd of earth crust is silica, I don't know, whether silica is same in stone, sand & dust, or not? I also want to know, whether Silicosis is a mechnical effect or chemical effect of silica?

Hmmm, the fine dust resulting from sanding or cutting a stone is different form a grain of sand in at least one critical aspect: It's very fine. The problem is breathing it. It is hard to breath sand. I don't see your point.
 
I want to understand, if Silicosis is caused by some mechanical blokages in lungs due to inhaling fine powder of stone & this inhaled powder directly accumaulate in lungs without any chemical change & cause Silicosis or not? Whether some chemical reactions are involved in this process? Btw, whether earth's dust(not sand) contains bigger particles of silica than stone powder?

I think there is a lot of information on this. Why don't you google it and look on pubmed? Then you could post here and add in the answers you find.
 
To check more acuurately, whether any of these reactions can be involved in getting Silicosis;

Silicon tetrafluoride is formed when sand (SiO2) is exposed to HF :

SiO2 + 4 HF(aq) --> 2 H2O + SiF4(g)

SiF4 reacts with water to give silicic acid :

SiF4 + 4H2O --> 4 HF + Si(OH)4(aq).

People with silicosis are at high risk for developing tuberculosis (TB). Silica is believed to interfere with the body's immune response to the bacteria that causes TB. Yearly skin testing to check for exposure to TB is recommended. Treatment with anti-TB drugs is recommended for people with a positive skin test. Any change in the appearance of the chest X-ray may indicate TB. (Silicosis)

I see your chemistry knowledge is increasing. Unless you stole that word for word.

Chemical reactions are not stolen one. These are available on many sites, nothing secret. I want to check any role of these reactions in our system. I think some HF is formed due to presence of fluoride in water.

How much HF (hydrogen fluoride) do you think is involved in any biological system?

Oh, that wouldn't be that bad unless he stole it from a board discussing the atmosphere of .... Venus and Mars ? :D (5th post down the page)

Plagiarism doesn't have to involve something secret. I can plagiarize from the latest avalable Harry Potter novel and it's still stealing.

Evidence?

Yeah, I agree.

It doesn't hurt to post links though.
 
Biological Role

The element fluorine and the fluoride ion are highly toxic.

More;

2F2(g) + 2H2O(l) O2(g) + 4HF(aq)

Wonderful. Does that include all substances that contain Fluorine in any form, at all concentrations?
 
Being science people, you tell me. I ask, I can be unclear/wrong,so pls don't concentrate on it. Pls concentrate on 'this only this' & avoid 'this & that', as I am now not reading that.

It is your claim. You back it up. I'm not doing your work. If you had to, Heavens forbid, open a freaking text book, do it!

Ok, as per your /modern undestandings.

Kumar,

If you can, just answer this one question - citing specific examples - and I will be more patient with you:

  • What have you learned from this forum/these threads that has changed your mind about a specific concept you'd previously thought was correct?

-TT

I could understand few cocepts which looked valid but still unclear to me. One such is that, substances can also effect physically by its refelected wavelenghts & specific pattern on which effect of most unclear energy based concepts, can somewhat base, Eg; effect of photograph. I just now, have to understand, how this effect can be stored as an information.

In respect of this topic, I am getting some indications of, relation of silica in earth may be responsible for many things--latent infections, activation of latent infections, removal of this in complete...etc. One thing looks me somewhat possible that extent of our direct physical exposure(not ingestion) can be related to extent of our health, in somewhat same proportion & imbalances in this exposure natural to us, may have some connection with getting imbalances in health/getting diseases in somewhat same proportion. We may had just not looked into & assessed this physical effects by reflected colour/WLs ,somewhat as cephalic effect, colour therapies etc..

I don't think you understood ThirdTwin's question. When you have posted ideas or questions here, and people have tried to answer your questions, have you ever changed or given up an idea because of their explanations? It wouldn't have to be your whole idea, just some hypothesis related to your idea.
When people answered your questions about reflected wavelengths, did any of the posts here (not the webpages you read on your own) give you information that changed your concept? If so, what was your original idea and how did it change? Or what idea did you give up?
