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”.
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.

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.

5. Design inspiration
The architecture features a triple-lobed
footprint, an abstraction of a desert flower
named Hymenocallis (spider lilies)
The tower is composed of three wings
arranged around a hexagonal central core.
Twenty-six helical levels decrease the cross
section of the tower incrementally as it spirals
skyward.
A Y-shaped floor plan maximizes views of the
Arabian Gulf. Viewed from the base or the air
6. Challenges
Weak soil
Mobility
Gravitational loads
Heat
Speed of construction
Wind load
Seismic activity
Fire safety
7. Foundation
The soil stratum of Dubai is very week so they had to excavate
up to 50m deep to get a hard rock structure
But the rock that they found was fragile and saturated with
ground water so that any hole made will be cured immediately
The engineers filled this with a viscous polymer slurry. This
pushes the rock and the ground water to the edges of the
boreholes to keep it open
Burj Khalifa uses a deep foundation design, consisting of both a
3.7 meter thick raft foundation and 192 bored piles
8. Mobility
The Burj can accommodate about 35,000 people at a time
The building consists of 57 elevators and 8 escalators some of
which travel at 35 kmph
Also has a service/ fireman's elevator which have a capacity to
hold about 5,500kg
9. Gravitational loads
The tower superstructure of Burj
Khalifa is designed as an all reinforced
concrete building with high
performance concrete from the
foundation level to level 156, and is
topped with a structural steel braced
frame from level 156 to the highest
point of the tower
10. Buttressed core
The structural system for the Burj
Dubai can be described as a
“buttressed-core”
Each wing, with its own high
performance concrete corridor walls
and perimeter columns, buttresses
the others via a six-sided central core
11. Cladding system
The exterior cladding is comprised of reflective glazing with aluminium and
textured stainless steel spandrel panels and stainless steel vertical tubular fins
The biggest challenge with glass cladding is the heat it absorbs- both UV
radiations from the sun and IR radiations from the heat reflected by the sand
The panels used have 2 layers. The outer layer has a coating of metal that reflects
UV radiation and the inner layer has a coating of silver to reflect IR radiation
12. Cladding system
Close to 26,000 glass panels, each individually
hand-cut, were used
The cladding system is designed to withstand
Dubai's extreme summer heat and wind speeds up
to 75kmph
A World War II airplane engine was used for
dynamic wind and water testing
13. Speed of construction
In a project of 1.5 Bn dollars, every day is precious
The formworks were fitted on to cranes and precast rebars were inserted into
them and concrete was then pumped into the formworks
The 25000 tonnes of concrete was pumped to the top floors by specially designed
machines that use a 630 Hp engine (greater than a Bugatti Chiron) in 14 minutes
The mixture needs to be in the right composition so as not to set earlier in the
pipes or not too late as to create delays in setting
It takes 12 hrs for the concrete to set and in this way a floor was completed every
3 days
14. Wind load
The higher the building goes the stronger the winds get and
in this region the winds were known to pick up speeds of
more than 80kmph but they diverted the loads by employing
some methods
Varying the building shape along the height
Reducing the floor plan along the height
Using the building shapes to introduce spoiler type of effects
Change the orientation of the tower in response to wind
directionality
Even with this strategic design, the 206-story Burj Khalifa still
sways slowly back and forth by about 2 meters at the very
top
15. Earthquakes
The region is said to experience moderate seismic activity and thus is not the
governing factor in the design (wind load is the governing factor)
That being said, the structure can still withstand an earthquake which registers 6
on the Richter scale
16. Fire safety
Fire alarms, sprinkler systems, stairwell pressurization and smoke evacuation
systems are the primary fire safety system
The Burj is also equipped with 38 fire and smoke resistant evacuation lifts
Pressurized and air-conditioned refuge areas are designed on almost every 25th
floor of this tower to ensure better safety as occupants can’t walk down160 floors
in one go
These refuge rooms are made of RCC and fire proof sheets that resist the heat up
to 2hrs and have a special supply of air which pumps through fire resistant pipes
17. Some awe-inspiring facts
During peak cooling hours, Burj Khalifa requires about 10,000 tons of cooling,
equivalent to the cooling capacity of approximately 10,000 tons of melting ice
The ambient temperature at the tip of Burj Khalifa is six degrees cooler than the
temperature at ground level
If you were to take all the concrete used in Burj Khalifa and lay a sidewalk, it would
be 2,065 kilometres
It took 22 million man hours to build the tower
18. Some records held by the Burj khalifa
Tallest building
Tallest man-made structure
Tallest free-standing structure
Largest number of storeys
Highest occupied floor
Highest outdoor observation deck
World record for vertical concrete pumping
Tallest service elevator
Highest aluminium and glass facade
19. Questions
What is the reason for the selection of the shape of the structure instead of the
traditional forms (apart from the reason to redirect winds)?
The temperatures reach up to 50 degree Celsius and are not suitable for the concrete
to be allowed to set. What would you have done to overcome this problem?
