COMPARATIVE STUDY AND QUALITATIVE ANALYSIS OF DIFFERENT BRANDS OF COLD DRINKS AVAILABLE IN MARKET
PURPOSE:-
In recent days, soft drink brands were put into various questions regarding their purity. News flashed that they Contain harmful pesticide, which arouses many interests in knowing its contents because I have been drinking them for years I wanted to confirm that whether the charge imposed on these brands are true or not.
Another fact which inspired me to do this project is that I am in touch with qualitative analysis whose knowledge of other factors helped me to do so.

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.
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.

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.

8. INTRODUCTION
The era of cold drinks began in 1952 but the
industrialization in India marketed beginning with launching
of Limca and Goldspot by purely 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, Miranda, and Limca to give feeling of
lightness, while Pepsi and Thumbs up to activate Pulse and
brain.
9. 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 forth on shaking
the bottle.
The carbon dioxide gas is dissolved in water to form
carbonic acid which is also responsible for the tasty taste.
Carbohydrates are the naturally occurring organic
compounds and are major source of energy to our body.
General formula of carbohydrates is Cx(H20)y.
10. On the basis of molecule size carbohydrates are classified
as: -
Monosaccharide, Disaccharide 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 body to the extent of
about 0.1%. Sucrose is one of the most useful
disaccharides in our daily life. It is widely disturbed in
nature in juices, seeds and also in flowers of many
plants.
11. 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 where 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.

the different brands of cold drinks namely- Coca Cola,
Sprite, Limca, 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
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 ha Minimum amount of dissolved carbon dioxide.
28. CONCLUSION
Disadvantages of Cold drinks;-
Soft drinks are little more harmful than sugar solution.
As they contain sugar in large amount which cause problem
in diabetes patients.
Soft drinks can cause weight gain as they interfere with
the body’s natural ability to suppress hunger feeling.
Soft drinks have ability to dissolve the calcium so they
are also harmful for our bones.
Soft drinks contain “Phosphoric Acid” which has a pH
of 2.8 so they can dissolve a nail in about 4 days.
29. Uses of Cold Drinks
Cold drinks can be used as toilet cleaners.
They can remove rust spots from chrome car humpers.
They clean corrosion from car battery terminals.
Soft drinks are used as an excellent detergent to
remove grease from clothes.
They can lose a rusted bolt.
For transportation of soft drinks syrup the commercial
truck must use the hazardous matter place cards reversed
for highly connive material.
Soft drinks have also ability to remove blood so they
are very harmful to our body.
