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.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

sufficient.
•Both remain in the tissues in an active form for
prolonged periods thus maintaining a residual
activity for prolonged periods.
www.indiandentalacademy.com
27. Method of sterilization
Moist heat (autoclaving)
Dry heat
Chemicals (chemiclaving)
(hot air oven)
www.indiandentalacademy.com
28. Moist heat
•Moist heat denatures & coagulates the
protein of microbes.
•Better than dry heat because of its higher
efficiency of penetration.
•Due to latent heat of vaporization present in
moist heat.
www.indiandentalacademy.com
29. TYPES OF AUTOCLAVES
POROUS LOAD AUTOCLAVES :
1.
Autocycled high pressure vacuum models
.
Air is evacuated from the metal chamber
by vacuum suction.
1210 C , AT 20 lb pressure for 30 min.
Towels ,suture materials,cotton rolls,
rubber gloves ,root canal instruments.
www.indiandentalacademy.com
30. SMALL BENCH TOP AUTOMATIC
AUTOCLAVE
Work on the principle of downward
displacement of air as a consequence of
steam entering at the top of the
chamber.
Temp of 136oc ,at 32 lb pressure for 5
min
www.indiandentalacademy.com
32. DRY HEAT
Less effective than moist heat
Higher temperatures ,longer periods &longer
heating up time required for sterilization (45 min
to reach 160oc).
Should have a time clock on the door ,so items
cannot be added or removed during the cycle & a
fan to distribute the heat evenly.
www.indiandentalacademy.com
33. CHEMICAL STERILIZATION
Combination of formaldehyde,alcohol,acetone,ketone &steam at
20 psi serves as an effective sterilizing agent.
biocidal action of formaldehyde depends on its alkylation of
microbial nucleic acids,which control protein synthesis.
Takes longer time than an autoclave (30 min)for packaged
instruments (shorter than hot air oven)
www.indiandentalacademy.com
34. Advantage of chemiclave :
Shorter cycle
Lack of corrosion of instruments /burs.
Adequate ventilation must be provided
in order to expel the residual fumes
released on opening the chamber at the
end of the cycle.
www.indiandentalacademy.com
35. Ethylene oxide gas
sterilization.
A flammable ,explosive and toxic gas to which
all types of microbes are susceptible.
Biocidal activity is due to alkylation and hence
causes denaturation of microbial nucleic acid.
Biocidal activity increases in the presence of
moisture.
Plastic ,metal,rubber or cloth can be sterilized
without damage.
Equipment is costly & gas is toxic.
www.indiandentalacademy.com
36. STERILIZATION BY GAMMA
IRRADIATION :
Used for needle,sutures ,gloves etc
GLASS BEAD STERILIZATION :
Heating glass beads in a chamber into
which instrument is inserted for 10-30
sec.
2100c –230 0c .
Suitable for very small instruments like
www.indiandentalacademy.com
R.C.T instruments ,burs ,pliers etc.
37. Water boilers…
•does not achieve sterilization as many spores
can with stand it.
•Cross infection from contaminated water
containing bacterial spores not killing by
boiling.
www.indiandentalacademy.com
39.
PHYSICAL MONITORING :Refers to periodical observation of
displays or gauges on the sterilizer
during a cycle to ensure the sterilization
process.
www.indiandentalacademy.com
40. Chemical monitoring.
1.
2.
Two types are available
process indicators :- consist of colour
changing material (liquid /paper) which
changes color upon exposure to appropriate
sterilization cycle.
TST strips (TIME ,STEAM,TEMPERATURE)
change color when all parameters have
been adequately achieved in the
sterilization cycle.
www.indiandentalacademy.com
41. BIOLOGICAL MONITORING.
Indicator used are heat resistant
bacterial spores (bacillus
stearothermophillus ,bacillus
subtilis )
If the spores are killed ,then less
resistant microbes are killed more
readily and sterility is achieved.
www.indiandentalacademy.com
42. Classification of instruments to
be sterilized
Critical
Semi critical
Non- critical
www.indiandentalacademy.com
43. Critical
Surgical other instruments used to penetrate
soft tissue / bone.
Should be sterilized after each use.
eg :-forceps ,scalpels,bone chisels,scaling
instruments,surgical burs.
www.indiandentalacademy.com
44. Semi critical
Instrument that do not penetrate soft tissue /
bone but contact oral tissues.
eg :-mirrors ,plastic instruments,burs etc.
www.indiandentalacademy.com
45.
Non critical :Items which do not come into contact

Manual cleaning
Ultrasonic cleaning :Employ piezo-electric oscillators situated underneath
S.S enclosures to create oscillations in a fluid filled
tank.
Oscillations are transformed into a series of high
frequency sound waves, which cause intense
microscopic cavitation in the fluid.
Large number of these tiny bubbles collapse creating
minute vacuum areas which are responsible for the
scrubbing effect.

80. Corrosion of instruments.
corrosion is an electrolytic process in which the contact of
two dissimilar metals sets up a potential difference
resulting in an electron flow.This flow leaves behind reactive
ions that readily combines with atmospheric oxygen to
form oxides (rust).
Corrosion resistance of orthodontic grade steel is directly
proportional to its carbon content and the chromium content
