What is the effect of pollution on ajanta and ellora caves?

The carvings in the caves are damaged, they have lost their shine and gloss. this is due to the industry pollution and traffic as well.

How do you reduce tire noise?

Tire noise can be caused by the tread pattern used on your tires. Off road tires have a deep tread pattern to give better grip on soft surfaces. Change to a road tire.

Road noise can also be caused by worn suspension components, especially the rubber bushes. Check that yours are not worn. They go soggy or split with age.

Why do shoes make noise annoying noise?

How will you differentiate between noise and music?

noise is an unpleasant sound(screaming, yelling,etc.)... music has a tune to it(singing).

2nd answer.

I think that this is a very hard question and is completely a matter of opinion. It is very hard to determine when music turns to noise and vice versa. Some people consider most popular music to be noise. Some others only consider heavier genres to be noise (like heavy metal, grunge, black metal, etc.). Some others mainly consider rap to be noise. Even some consider it noise when it is too "soft."

You could probably make a very general argument by saying that any type of sound that is organized and has some sense of musical structure may be considered music rather than noise. But then you would inevitably have to include serialism, which, although usually lacking any sense of standard tonality, can still be considered to be highly organized and very structured. And by trying to make this argument, you would then eliminate aleatoric music, which, although a large portion of this music (if not entire pieces) can be determined completely by chance (i.e. the roll of some dice), it is still considered by many to be music, non-the-less. This type of music could be considered by some to eliminate any argument that music is always made on purpose and with intent or even for the purpose of expression.

I believe that there is no possibility for a universal standard on what is music and what is noise and therefor it is completely determined by personal preference and opinion and is different from one person to the next.

How do you prevent flatulence?

Chew your food more (20-40 times before swallowing). Chewing food for longer breaks down the food into very small pieces making it easier to absorb and less work for the stomach. Also chewing more increases the amount the natural starch enzymes have to breakdown food in the mouth before it is processed to the stomach. chew chew chew, the harder and tougher the food item (meat or fibrous vegetables) the more chewing is needed to prevent gas.

I actually found that B-Complex vitamin intake prevents you from farting. I am a vegetarian and eat a lot of Broccoli, beans, cauliflower and chickpeas; that are known by causing you to fart. Since I started taking a B-Complex vitamin daily with lunch, the gases have gone. Good luck!

You cannont prevent farting. It is a natural reaction to food digestion. Everyone farts. You can help not fart as often by not eating foods that make you gassy. Everyone's body is different, but stuff like broccoli or beans are a big one. And there is a commercial for Bean. It is supposed to help with gas, but I have never known anyone who has used it so I can't say if it works or not.

You made my day and I had a good laugh over this one!

Unfortunately, "passing gas" isn't that funny at all, and for some people it can be darn right embarrassing! These are things that can cause it:

Different foods such a chili, beans of any sort, brussel sprouts, cauliflower, broccoli, rice (believe it or not), turkey, chicken and even red meat. This is usually an indication that you do not have the right balance of acids in your stomach.

First, go see your doctor and discuss it with him/her and then go to a good health food store and they will give you herbs to balance the stomach acids.

"Passing gas" is usually normal off and on, but all the time ... there is something usually going on in the digestive tract.

I would also like to add that certain medications can cause these problems, so either look them up on the internet or post it on this board and I can look the medication up and see if this is your problem.

Wind beneath your wings Marcy

Farting usually means you arent eating the right foods, or too many bad ones. Foods high in fat can also cause farts if eaten constantly. If you don't eat bad foods constantly, it is probably just a natural thing that happens. Beans and cabbage are also main contributors.

Just for the record... Gas X and other medications for gas don't prevent you from passing gas. They are for the symptoms associated with gas (bloating, pain, etc.) In fact I read that what it does is make the small air bubled get together to make big air bubbles thereby allowing them to be more easiy passed by belching or passing gas.

I was bumed out to learn that, after a big bowl of beans I take them so I wont go "poof" in the night. It actually helps the "poof" but at least it does stop the pain. ; )

I had such a laugh reading the answers etc. Don't eat ! 14 times a day is the average. Quantity of food is part of it. But the biggest thing is that it is fun !!! It should be a positive socially humorous event ! We are gas producers and we should change the way we see it.

I heard one kid say the other day. Nice out ! What stuffed shirt with a tight corsett said that it was bad ! To many stick in the muds in the world ! Let's live and enjoy.

Many people get gas from eating beans, broccoli, etc. because they don't have the proper intestinal flora to digest them. There is a commercially available product called Bean-o, which contains the flora. It's in liquid or pill form. Just one or two drops on the first bite of chili, beans or broccoli (or one pill) will prevent gas. Trust me, it really works. In the US it is available at most grocery stores.

If you gas problem is interferring with your social life, or it continues, you may have irritable bowel syndrome. See your doctor for treatment options.

I have about 6 nurses in my family and all of them have said gas is a natural body function. And they're right! But I agree with the answer above, if it's interferring too much then you could have IBS. Eat lots of fiber! Good luck.

In women, the menstrual cycle can contribute to flatulence, as embarrassing as it is.

Personally, I have found that my ability to socialise successfully is limited if I eat excessive amounts of snack foods (dried apricots, nuts, salty crackers, potato chips, candy, chocolate, oatmeal are some that I have noticed).

So eating small meals, especially for foods that you are particularly sensitive to (it may take time to figure these out) may help.

Can you check if paxil or abilify causes rancid smelling gas?

I am going to take my 14 year old son to the doctor. He does have a long history of this problem. He says that before he can open his mouth to excuse himself, it is too late. (I think he may be allergic to milk..he was as a child and so was I and a sibling) At this point the teachers at his school are threatening to give him a detention for each fart in class. (I don't think they can lol).

:You can't really. Gas will be created when food is digested. Some foods will create more gas than others and you can avoid eating these. The Right :

First, you don't prevent gas. You can lesson the amount of gas by avoiding some foods. Some of the advice above is not correct. Suggesting that you should increase fiber to prevent gas is ludicrous. Soluble fibers like beans, broccoli, cabbage, and oatmeal, etc. cause gas. Non-soluble fibers such as breads, etc. do not cause gas. But both are important to your health - so eat them. You can time you meals with your digestive cycle - oatmeal for breakfast and a walk (outside, alone) in the afternoon; not beans for lunch and a car-pool ride after work. If you are lactose intolerant, this will also cause excessive gas, usually sooner than your normal digestive cycle - within a couple hours. There are over-the-counter products that help with gas. Simethicone (Gas-X or similar brand) doesn't actually reduce the gas produced in the intestines, but it may help with any pain or bloating. Beano contains enzymes that actually do reduce gas cause by certain foods. So you may want to see if it works for you. Bottom line: normal gas is 'normal' and healthy and fiber is too important to take out of your diet. Which would you rather have: a heart attack or a fart attack?

The Useful :

Stopping farts all together is of course not what somebody has a problem with. How to stop excessive flatulence however would be more useful and I think more what the original question had in mind. There are many reasons for excessive flatulence, it could be a problem with your organs, your diet, you could be sick or other things. The first step in addressing the problem is to determine what exactly is causing your excessive farting. Once you have done that, you are well on your way to solving the problem. If the problem persist after making changes to your diet, see a doctor.

personally i think farting is just the best, its funny especially when you say does anyone smell petrol ? that always gets somone! be loud be proud ! coincidently i just let one rip yeeha !!! : ) stinky poo to all of you and no returns white rabbit

What is the difference between an alto and a mezzosoprano in vocal music?

Altos and mezzos

Alto is one vocal range lower than mezzosoprano. For more information, go to and type in "alto" and "mezzosoprano". There are some nice graphics on Wikipedia that can show you the difference in the notes that altos sing compared to the ones that mezzosopranos sing.

More importantly, the way to distinguish between a tenor and an alto is very simple. Only one has hair on their back.

[ a tenor is usually a guy and alto's are more common in women ( XoXo Team Jasper Fan ]

you usually hear Mezzosoprano in Opera. You hear alto there too but alto is more common in girls that sing todays music such as Taylor Swift and Demi Lovato. An example of a mezzosoprano would be Emmy Rossum. Emmy sings in The Phantom of the Opera as Christine Daee. Christine Daee is suppose to be a Soprano but Emmy is a mezzosoprano so her voice is much lower in octave than the original script had called for. Can you sing both mezzosoprano and alto? You sure can. I sing both alto and mezzosoprano. Can you sing both mezzosoprano and soprano? No and yes. If you can control your octaves you can go higher and sing Soprano if you sing mezzo but only if youre trained, which I was. Soprano usually breaks glass. Mezzo does not break glass.

What should you do to keep butcherblock surfaces clean and in top shape?

Wood butcher block can take much hard wear and tear, be resurfaced or repaired, and continue looking good for many years. Before using a new butcher block, season it to prevent staining and absorption of food odors and bacteria. A mineral oil finish is preferable to polyurethane or varnish because the oil finish is easy to maintain and to repair if the wood surface is damaged. An oil finish helps to prevent the wood from cracking or pulling apart at the seams. Although boiled linseed oil will work, mineral oil is preferred because it will not turn rancid. Before applying oil to butcher block, warm the oil slightly. Apply oil with a soft cloth, in the direction of the grain, allowing the oil to soak in between each of the four or five coats required for the initial seasoning. After each treatment, wait about four to six hours and wipe off oil that did not soak into the wood. Re-oil the butcher block monthly or as often as needed. Wood butcher block counters have all the characteristics of solid wood. They will shrink or expand as the moisture content of the wood changes. Extreme dryness may cause cracks. Any cracks that appear should be filled with wood filler, sanded smooth, and the entire block given a good coat of oil. [Info from the Home Maintenance And Repair Database at the Michigan State University website] In UK slaughter houses butchers blocks are cleaned using soapy water and scrubbing hard with a wire brush

What is a granular noise?

It is a cause of error in Delta Modulation. When the original signal is nearly constant the output will vary due to long step size and appears to be varying.


If the original signal has small variations the output wave will look like square wave and will be recovered as DC component.

Scooter engine making loud noise?

If a scooter engine is louder than normal if could indicate one of several problems. You should check the oil level straight away, especially if it is a two stroke engine, as lack of oil, especially two stroke can cause major damage to the engine, and if the engine is running dry it would definitely be louder than normal, and could seize if you continue to use it.The most likely cause of the noise is the exhaust. If a hole has developed, due to rust then the scooter will be much louder than normal. You should visually check the exhaust for any damage. You should also check that the exhaust has not come loose at the manifold (where it joins the engine). If it loose you will just need to tighten it. If there is a hole it will need replacing.
You should also take to a scooter dealer or mechanic as soon as possible, as they will be able to find out what is causing the noise, and they will be able to repair it.

What causes a tapping noise when starting the engine?

The tapping noise while warming up in the Grand Am GT's is nothing to worry about. These vehicles have the 3.4 Liter V6 engine and due to the design of these engines, it is simply oil entering the engine that causes this sound. If you noticed once it is warm the tapping ceases. Like I said need not to worry because this is common.

I would not be driving this vehicle for a couple of reasons. If you are loosing coolant on a continual basis, regardless of how much is lost, it has to go somewhere. If you do not see any pooling under the vehicle, then it is leaking inside the engine. If the latter is true, then coolant in the engine will dilute the oil, and create a cloudy oil residue, or if you are getting oil into the coolant, you will see a 'rainbow' on top of the coolant in the radiator or overflow. The tapping, I think, from the limited information, is the Valves not getting the Oil due to low oil pressure. Once the engine warms up, and the Oil pump starts to flow the oil, the tapping stops. Many vehicles, especially GM and Chevy do this. I would not be overly concerned about the tapping, but I would be concerned about the coolant leak. An easy way to see if you have an external leak is to go to a local parts store, and purchase a leak test kit, which usually is a dye, which can be seen with a blacklight. Kids love helping at night with this! Good Luck it might be your water punp you need a stronger one. or nr oil too the head Adding to answer: Take vehicle to repair facility and have a Carbon Block Test done,it will also determine if Carbon Gases are entering the coolant system.As far as the tapping, switch to synthetic oil,it costs about twice as much but is well worth the expense. answer does the noise go away shortly after starting? if so the tapping noise is caused by cold and insuufient oil in the lifters on your tappets as the engine stands, not running, the oil that was circulating while running, goes to oil pan on starting, the oil needs to be circulated back to all parts, try an oli change with correct viscosity oil sometimes a good oil additive such as LUCAS ENGINE OIL ADDITIVE will stop this rattle all cars will have same problem as they get older

What's a description of Crystal Waters Lagoon?

Crystal Waters Lagoon is a large lagoon near Coffs Harbour, in New South Wales, Australia. It is a wetland in danger from various factors. It is seriously affected by the weed known as Salvinia, which blankets the surface of the water and kills much of the organisms below that rely on the sun. There is a golf course nearby which allows nutrients to flow into the lagoon. There is also a residential area with hard road surfaces which allow run-off from petrol and oil spills.

What is the cause of loud noise when the engine starts the first time of the day?

Possibly, a misfortunate cat sleeping under the hood. This bang is probably a loose engine mounting bolt. The noise is probley from bad rod bearings once the oil pressure is up they quiet down.After it sits a long time(over night) the oil drains down and will be noisy It may last a long time just make sure the oil level is good

Why noise is measured in decibels?

Because of the large variations in energy, between a weak sound and a loud sound, a logarithmic scale - like decibels - is appropriate.

How can you keep your nation clean and green?

you can do that by like doing stuff that can help like use a bike instead a car, like that stuff ya' know

How can you make a model on noise pollution?

Get more than 1 person, in a room, with their own music, emmitting devices. The more the better, and, make sure that they all like different kinds of music, and, insist they play their own preference, at, their preffered, outdoor, volume. Then, just mange the group, for your variables...............chuck

Aims and objectives of noise pollution?

There aren't many aims or objectives for noise pollution. Many aims are against noise pollution because it is physically harmful to the human body.

What are the effects of land pollution?

Effects of Land Pollution

1. Effects on Climate

Land pollution can affect the general environment of the Earth. Land pollutions leads to loss in the forest cover of Earth. This is in turn going to affect the amount of rain. Less rains mean lesser vegetation. The effect of all different kinds of pollution will eventually lead to problems like acid rains, greenhouse effect, global warming. All of these problems have already initiated and need to be curbed before the situation runs out of control.

2. Extinction of Species

One of the major causes of concern is the extinction of species. Species are pushed towards endangerment and extinction primarily by two processes. Habitat fragmentation is the fragmentation of the natural habitat of an organism; cause primarily by urban sprawl. Habitat destruction, on the other hand, is when land clearing adversely affects animals special such that their natural habitat is lost. Both the actions can cause some species to go extinct and others to become invasive.

3. Biomagnification

Biomagnification is the process in which certain non-biodegradable substances go on accumulating in the food-chain (in one or more species). The most common example is of methylmercury in fish and mercury in eagles. Not only does biomagnification put the particular species at risk, it puts all the species above and below it at risk, and ultimately affects the food pyramid.

4. Effects on Biodiversity

Species extinction and biomagnification is going to overthrow the balance of nature very significantly. The main reason for this is disturbance created in the food chain. To give you a very simple example - on account of biomagnification of mercury in eagles, they might go extinct in the subsequent years. However, we know eagles prey on snakes. Less (or no) eagles will then result in more number of snakes!

As you may have realized, land pollution is indeed going to affect a lot more things than we though it will. Hence, I leave you with some corrective measure you can take on a personal level to reduce land pollution.

•Encourage organic farming - buy organic food

•Proper garbage disposal - separate your garbage before you give it to the garbage collector; and strictly say NO to plastic

•Encourage recycling - buy recycled products, notebooks, paper, etc.

•Restrict use of herbicides and pesticides - they are not only used in farm, but in your own backyard as well

If we reduce our contribution to garbage and litter, therein itself we will be able to significantly reduce land pollution and probably curb it entirely in the near future. Also do realize this isn't only about land pollution; it is about all kinds of pollution. We need to take steps to prevent damaging our Earth. We have no other place to go.

Does Polyalthia longifolia reduces noise pollution?

Yes- see link.

Polyalthia longifolia is probably a very good choice as it grows straight up, and a line of them acts as a natural wall.
