This document discusses various types of air pollution including smog, acid rain, the greenhouse effect, and the ozone hole. Smog occurs when dust and chemicals float in humid air, posing health risks. It contains sulfur dioxide from burning fuels. Acid rain forms when sulfur and nitrogen oxides from fuel combustion react with water, lowering the pH. The greenhouse effect involves carbon dioxide trapping heat in the atmosphere from fossil fuel combustion. The ozone hole is a phenomenon where chlorine from freon compounds thins the ozone layer, increasing UV exposure.
this presentaion will tell you about air pollution.. its my first time to upload a ppt. so sorry for the mistakes i have made..but next i will try my best

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. What is it?
◦ Air pollution is a condition in
which chemical substances
have a negative impact on
the environment, including:
people, animals or soil.
◦ Most polluted air is produced
by heating devices and, for
example, garbage thrown into
them.
◦ Below we present the
sources of pollution and their
division.
3. Biodegradation
◦ This is the process of bacteria
decomposing various chemical
substances into simpler compounds; only
some of the produced plastics
(detergents) undergo this activity.
4. Smog🌫️
◦ Smog is created by dust and chemical compounds floating in humid
places that pose a threat to human life. Smog is acidic due to the
sulfur dioxide it contains, produced by burning fuels.
◦ The name comes from English and is a combination of two words –
smoke-fog = SMOG
Why does smog occur?
◦ Big fog
◦ No wind
What consequences does it bring?
◦ For people: asthma, watery eyes, cough, allergies
◦ For the environment: reduced plant growth, animal diseases.
Sulfur dioxide from fuel impurities is the main cause of acid rain.
5. Acid rain
◦ Rainwater is more acidic than regular rain. In
natural rainfall, the pH ranges between 5 and
6 because rainwater contains dissolved
carbon dioxide, which forms dilute carbonic
acid. Sulfur and nitrogen oxides produced
during fuel combustion react with water in
the atmosphere. Sulfuric and nitric acids are
then formed, lowering the pH of rainwater to
approximately 3.
6. Greenhouse effect
◦ It involves trapping solar energy
in the Earth's atmosphere, which
contains carbon dioxide, which
leads to an increase in average
temperature. The source of an
increasing amount of CO2 is the
combustion of fossil fuels.
7. The ozone hole
◦ A phenomenon occurring in the upper parts of the
atmosphere of the gradual disappearance of the natural
ozone layer, which protects the Earth from harmful
ultraviolet radiation. This effect is believed to be
accelerated by the presence of chlorine, which
accelerates the reaction of the breakdown of ozone into
oxygen. Chlorine comes mainly from the breakdown of
compounds such as halogens. These include Freon
used in aerosols or cooling liquid in refrigerators.
Although international efforts are currently being made to
reduce the use of freons, some scientific communities
believe that the effort in this direction must be even
greater
8. Heated sewage
◦ Fluids used from power
plants of other plants
increase the temperature of
water, which in turn reduces
the amount of oxygen
dissolved in it and disturbs
the natural balance of the
water environment.
9. Eutrophication
◦ This means too much plant development due to the
excess of nitrogen and phosphorus compounds in the
water. These compounds come from artificial fertilizers.
◦ Eutrophication reduces the oxygen content in water, which
leads to the disappearance of aquatic flora and fauna.
13. Conclusion
◦ 1. There is more smog and various other pollutants in the
evenings because a lot of people smoke in stoves, which
adversely affects the environment
◦ 2. On a windy/warm day, there is less smog because
pollutants stay close to the ground and do not spread quickly.
