Bhaskar Sharma, a 12th grade student, conducted a chemistry project to qualitatively analyze and compare the contents of different brands of cold drinks found in the market. He performed tests to detect the presence of carbon dioxide, glucose, phosphate, alcohol and sucrose in drinks like Coca Cola, Sprite, Limca and Fanta. The results showed that all drinks contained these components, though their quantities varied between brands. Coca Cola had the lowest pH, making it the most acidic. Sprite contained the most carbon dioxide, while Fanta had the least. The project followed safety precautions and cited references used for background information.

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”.

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.
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

5. *Introduction*
The era of cold drinks began in 1952 but the industrialization in
India marked its beginning with launching of Limca and Goldspot by
parley group of companies. Since, the beginning of cold drinks
was highly profitable and luring, many multinational
companies launched their brands in India like Pepsi and Coke.
Now days, it is observed in general that majority of people viewed
Sprite, Fanta and Limca to give feeling of lightness, while Pepsi
and Thumps Up to activate pulse and brain.
6. *Theory*
Cold drinks of different brands are composed of alcohol,
carbohydrates, carbon dioxide, phosphate ions etc. These soft drinks
give feeling of warmth, lightness and have a tangy taste which is
liked by everyone. Carbon dioxide is responsible for the formation of
froth on shaking the bottle.
The carbon dioxide gas is dissolved in water to form carbonic
acid which is also responsible for the tangy taste. Carbohydrates are
the naturally occurring organic compounds and are major source
of energy to our body. General formula of carbohydrates is
CX(H2O)Y.
On the basis of their molecule size carbohydrates are classified as:-
Monosaccharide, Disaccharides and Polysaccharides. Glucose is a
monosaccharide with formula C6H12O6 .It occurs in Free State in the
ripen grapes in bones and also in many sweet fruits. It is also present
in human blood to the extent of about 0.1%. Sucrose is one of the
most useful disaccharides in our daily life. It is widely distributed in
nature in juices, seeds and also in flowers of many plants. The main
source of sucrose is sugar cane juice which contain 15-20 %
sucrose and sugar beet which has about 10-17 % sucrose. The
molecular formula of sucrose is C12H22O11. It is produced by a
mixture of glucose and fructose. It is non-reducing in nature whereas
glucose is reducing. Cold drinks are a bit acidic in nature and their
acidity can be measured by finding their pH value. The pH values
also depend upon the acidic contents such as citric acid and
phosphoric acid.

After conducting several tests, it was concluded that the different
brands of cold drinks namely:
1. Coca Cola
2. Sprite
3. Limca
4. Fanta
All contains glucose, alcohol, sucrose, phosphate and carbon dioxide.
All cold drinks are acidic in nature. On comparing the pH value of
different brands Coca Cola is the most acidic and Limca is least acidic
of all the four brands taken. Among the four samples of cold drinks
taken, Sprite has the maximum amount of dissolved carbon dioxide
and Fanta has the minimum amount of dissolved carbon dioxide.
16. *Precautions*
Some of the precautions which need to be taken care of are –
1. Concentrated solutions should be handled with immense care.
2. Hands should be washed thoroughly after performing each
experiment.
3. If possible, one should wear hand gloves to prevent from any
possible damage.
4. If chemicals come into contact with your skin or eyes, flush
immediately with copious amounts of water.
5. Never leave burners unattended. Turn them off whenever you
leave your workstation.
6. Never point a test tube or any vessel that you are heating at
yourself or your neighbour.
17. *Conclusion*
DIS-ADVANTAGES OF COLD DRINKS
1. Soft drinks are little more harmful than sugar solution. As they
contain sugar in large amount which cause problems in diabetes
patients.
2. Soft drinks can cause weight gain as they interfere with the body’s
natural ability to suppress hunger feeling.
3. Soft drinks have ability to dissolve the calcium so they are also
harmful for our bones.
4. Soft drinks contain “phosphoric acid” which has a pH of 2.8. So
they can dissolve a nail in about 4 days.
5. For transportation of soft drinks syrup the commercial truck must
use the hazardous matter place cards reserved for highly consive
material.
6. Soft drinks have also ability to remove blood so they are very
harmful to our body.
USES OF COLD DRINKS
1. Cold drinks can be used as toilet cleaners.
2. They can remove rust spots from chrome car humpers.
3. They clean corrosion from car battery terminals.
4. Soft drinks are used as an excellent ‘detergent’ to remove grease
from clothes.
5. They can loose a rusted bolt.
