6 Air Pollution Facts

Air pollution is the alternation of the normal concentration of gasses due to contamination with harmful substances. Air is vital for the entire organism in the earth including Human. Oxygen, which is vital for the life, is mixed in the air. Due to the air pollution, the various respiratory disease is creating havoc around the globe. The problem is severing in the urban cities. Millions of immature death around the globe takes place due to air pollution. Annually more than 5 trillion economic loss is indicated due to air pollution.

Narrow alteration in the normal concentration of gasses can be catastrophic to the biota. Let's take an example of the oxygen we breathe. Its concentrations in the air are twenty-one percentages. Rise in the level of oxygen to thirty percent creates inferno as oxygen helps in burning. Further, lowering of the oxygen concentration to ten percent can create a situation in which it will be impossible to burn any matters.

Normally it often heard that dilution is the solution to the pollution. This term applies only in the moderation. Due to inversion, which prevents the vertical mixing of the air, the effect of the air pollution increases drastically. Inversion is the condition in which the warmer air lies at the top of cold air.

Facts about Air Pollution

1. Causes

Automobile emission from the fossil fuels, emission from factories, pollen, dust, volcano, forest fire, dust storm, etc. Both the natural and anthropogenic sources trigger the air pollution.  

2. Particles

Particles are of serious health concern as they have lots of noisome effects on human health. A particle less than 2.5-micrometers gets dissolve in the blood and is excreted by the body. Particles less than 10 and 2.5 can create lots of noisome due to effective deposited in the lungs. Particles higher than 10 micrometers get settle by dry deposition within few hours of emission. Particles can originate naturally from the storm, volcanic eruption, fire, etc., and artificially by coal combustion, vehicles emission, etc.

3. Acid Rain

This is due to the emission of sulfur and nitrogen oxide, which create the acid in the atmosphere and falls to the earth as precipitation. Due to the acid content of the acid rain, there has been the massive destruction of the buildings and monuments. Traditional monuments get damaged by the acid rain can be devastating.  

4. Primary and Secondary Pollutants

Primary pollutants are those emitted directly into the atmosphere. The primary pollutants are the gasses from the volcanic eruption, carbon monoxide from the emission of the vehicle. Secondary pollutants are like the formation of ozone in the earth surface.  

5. Indoor Air Pollution

It is generally believed that indoor pollution is thousands of times higher than outdoor pollution. The asbestos from carpet, Formaldehyde from plywood, leads from paint are the frequent encountered indoor pollution. Indoors cooking mostly in the rural part, spraying chemical without proper ventilation can be worst.  

6. Preventive Measure

Using less fossil fuel, renewable energy electricity, efficient technology that emits less pollution, Law to control unwanted emission of different types. Awareness to the public especially adequate education to the children can be effective in controlling air pollution.

Father of Communism Karl Marx or Charles Darwin

Communism is the ideology developed by German philosopher and sociologist coined Karl Marx in 1940s. According to the communist ideology, common ownership of good are stressed. Although the root of this tenets dates back to a long time back.
This ideology predicts that property should be handled by the government and need to abolish the private property. Establishing the law and order followed by equality can make the economy of country prosperous.
Communism theory was based on the book by Charles Darwin named origin of species. The book predicts that human beings are the animals and are the by-product of long-term evolution over the thousands of years. Due to this, I will like to call Charles Darwin as the father of communism.

The first application of the communism was done in French where the priests from the church are brutally put to death. It was the unsuccessful revelation. Later Vladimir Lenin from Russia makes the modification in this tenet and did the successful revelation. …

Aghori Baba Living with the Dead Human Body

Aghori Baba is the most fearsome Baba of all Hindu sects. There are less than fifty Aghori Baba in India as well as Nepal due to their arduous and martinet lifestyle. Both the India and Nepal contain more than eighty percent of the Hindu population, which cremate the dead body. Aghori Baba Lives near the cremation ground and did the ritual in Pyre. Due to their practice of cannibalism, this Hindu sect is given the keen interest by westerners. 

This sect claims that by following the martinet lifestyle they are able to liberate themselves from the natural cycle of birth and death. Due to the excessive indulgence with alcohol and marijuana cigarette, they behave abnormally. True Aghori Baba remains active during the night and remains idle during the day. Any Facebook and Mobile number of Aghori Baba is almost all the potential traps.
The origin of Aghori Sects seems hazy. The scent of evidence suggests that a recluse of medieval Kashmir might have inducted this sect. Due to the varied of s…

Metallic Hydrogen: Superconductor Discovery and Skeptics

Hydrogen is the first element of Group 1 of the periodic table and is abundant in nature. They have one proton and one elector. Freezing at 253-degree centigrade hydrogen become liquid and is widely used in Rocket fuel. Under normal atmospheric pressure hydrogen atom pair up to form the hydrogen molecule. The metallic property of the hydrogen is displayed when it loses the electron.
First Hypothesis on Metallic Hydrogen
The scientist named Eugene Wigner and Hillard Bell Huntington, the Princeton physicist hypothesized that massive pressure on the hydrogen turns it into the metal. This was hypothesized in the year 1935 (1). Until now there has not been any successful experiment to test this hypothesis.

Metallic Hydrogen Discovery
The Post-doctorate researcher Dr. Silvera and Ranga P. Dias has published the finding of metallic hydrogen in Journal science. The published journal claims that they have made metallic hydrogen by applying 495 Gigapascals pressure at the temperature -268-degr…
