Cavities are caused by the action of acid on the enamel of the tooth. The acid is produced by bacteria in the mouth that feed on sugar (and, actually, simple starches, which are converted to sugar by saliva). The acid dissolves the enamel of the tooth surface causing little holes in the teeth.

What are you trying to etch?  For glass, get a Dremel tool, it works great.

Abrasion by wind-driven sand.\nParticle removal by wind alone.\nDecomposition and weakening due to sunlight (especially the UV).\nCracking due to temperature changes.\nThis doesn't include biological damage which can be severe due to chemicals secreted by various growths such as lichen.

During acid hydrolosis, it is in fact a water molecule which gets attached to the alkene, forming an alcohol.\n\nThe H+ from the acid attacks the pi bond of the alkene.  This is because the H+ is an electrophile and attacks the high electron density of the pi bond.\n\nAs the H+ binds to the alkene, the pi bond is broken and an intermediate carbocation is formed.  An OH- from the water will quickly bind to the carbocation, forming the alcohol.\n\nThis reaction is an example of an electrophilic addition reaction.

six months of continuous smoking does create a damage...i think u should go and take doctor's help...hope it will be nothing serious..best of luck!

Nothing to worry about-its happened to me a few time.You probably did bruise/scratch yourself at work.Put some neosporin on it and unless it gets infected just forget about it.

The only thing I could find on this topic is the use of Hydrofluoric acid for chemical etching of glass. But this is not etching cream and is extremely corrosive and toxic. I am not sure but the etching cream could be this acid diluted and suspended in a unreactive cream. This is just a guess though, good luck.

Some spam is just being generated by viri. For example the one you mention seems to have an attachment. If the attachment has malicious content, and the email reader is set to automatically open it, the damage is done as soon as the email gets through the spam filter.

It doesn't usually cause abrasion. Powerbrushes work automatically so force should not be applied. Toothpastes itself contains abrasives but that doesn't cause the abrasion on your gums, it is usually the force you apply. =)

ever heard of ultra sound.  It can be used.  But the frequencies and power needed to produce results in some things would actually cause damage to surrounding tissue.

1. The most common reaction is contact DERMATITIS, or skin inflammation.  Repeated skin contact with resins and hardeners may also cause chronic contact dermatitis, which is usually milder but longer lasting. If left untreated for long periods it can progress to eczema, a form of dermatitis that can include swelling, blisters and itching.\n\n2.   ALLERGIC DERMATITIS is a more serious problem, but less than 2% of epoxy users are likely to get it. Allergic dermatitis is when the body hyperreacts to an allergen.  You are most susceptible if you have been grossly overexposed to epoxy or if you are inherently sensitized or allergic to a component of epoxy.  Once sensitized, additional (and sometimes increasingly severe) reactions become likely upon future exposures, even to tiny amounts of epoxy. It is difficult, but not impossible to prevent recurrences. Resume epoxy use only after symptoms disappear, and strictly follow the recommended handling procedures to prevent exposure.\n\n3.  Inhaling concentrated epoxy vapors, if done frequently or for long periods, can irritate your respiratory tract. Exposing sensitive skin areas, like the eyelids, to highly concentrated epoxy vapors may cause itching and swelling.   Never breathe the sanding dust of partially cured epoxy. Epoxy chemicals remain reactive until they have cured. Serious health problems can result from sanding epoxy before it is fully cured. When you inhale these dust particles, they become trapped in the mucus lining of your respiratory system. The reactive material can cause severe respiratory irritation and/or respiratory allergies.\n...breathing any nuisance dust will worsen existing respiratory problems. Smokers and others whose lungs are under strain are far more likely to develop serious respiratory problems.\n\n***Note--I did not just copy and paste this info.  I took the time to copy over the info that was important, as your question is of a serious nature--and deserves serious attention.  I would also recommend asking to see the MSDS sheets for the epoxy you are wokring with to familiarize yourself with what you need to avoid to prevent further sensitization.  Good luck and take care of yourself.

The damage may not be immediately evident, but little by little the components in a computer are damaged by Voltage Spikes. Voltage spikes occur, not just during electrical storms but also from other electrical equipment like fluorescent lights and electric motors.\nI thought that i was protected but I used to have component failures until bought a good surge suppressor and I don't mean the cheap things they sell in the computer stores. You need to get one that comes with a guarantee, like "This unit will perform as intended for 10 years or we will replace it free of charge".\nI have seen so call surge protectors that have lights on that tell you that it is working. After a voltage surge, a pop was hear and the thing rattled when shaken. The light, however, still came on.\nI recommend Innovative Technology  surge suppressors. They have an excellant sine wave follow device that I have been using for over 10 years. I have not had any hardware failures since I bought it.\nIf the computer is turned OFF, it can still be damaged. It needs to be unplugged to be safe.

Wire logging is after the hole is drilled, different tools are sent down to the bottom of the hole. the tools are raised back to the surface very slowly. These tools gather different type of info down the well (gas pressures, geology formations, depth, tempurature and a lot more that I cannot explain). As for perforationI hav no experience with that,so I cant help you.

Plz see ur doc urgently.\nThis might even require USG or other scans to see if there is physical damage.\n& that obviously can't be done on Yahoo answers, can it?
