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.

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.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. Restoration are the various ways a dentist can replace or
“restore” missing teeth or missing parts of tooth structure.
WHAT IS DENTAL RESTORATION???
When
are
they
used or
placed
?????
Tooth with carious
lesion
(Cavity)
Used for cosmetic
reasons to correct
aesthetic concerns
To replace missing or
damaged tooth
To repair a broken
or cracked tooth
Any treatment whose goal is
to restore the function,
integrity and morphology of
missing tooth structure
resulting from- caries or
trauma
3. RESTORATIONS SEEN ON
RADIOGRAPH
Metallic and Non-metallic
Metallic- Amalgam, gold, stainless steel, chrome, post and core and porcelain-fused-to-metal
(PFM) restoration.
Non-metallic- Composite resin, porcelain crowns, bridges and acrylic restorations.
All dental images should be evaluated while patient is still present.
Number of dental materials look very similar on x-ray; therefore, a clinical exam of the
patient is needed to gain information necessary to verify what is being seen on the x-ray.
4. AMALGAM RESTORATIONS
Common restorative material.
Mixture is made of: Silver, mercury, tin.
Inexpensive.
Less aesthetic material.
Absorbs most of the x-ray beams before they reach the receptor.
Radio opaque (light or white) on dental x-ray.
6. Amalgam overhangs
Extensions of amalgam beyond the
crown of the tooth into
interproximal region.
It is result of improper placement
of the amalgam restoration.
Material extends beyond the
surface.
Disrupts the natural cleansing
contour of tooth.
Easily seen on radiograph.
Traps food and bacteria therefore
contributes to bone loss.
Must be removed.
7. Amalgam fragments and amalgam tattoos
Sometimes when the
amalgam restoration is being
placed- particles fall off and
get embedded into the
adjacent soft tissue.
Soft tissue may discolor
overtime- this discoloration
is called “amalgam tattoo”.
Particles embedded in soft
tissue can be seen on
radiograph.
8. GOLD RESTORATIONS
Not easily distinguished from other metallic restorations on dental x-ray.
Radiopaque with smooth contours and regular borders seen on radiograph.
Large radiopaque restoration with smooth borders are seen on radiograph- is
most likely made of gold.
Smooth contours and regular border.
Gold restorations may include: crowns, bridges, gold foil, gold inlays and
onlays.
13. STAINLESS STEEL RESTORATIONS
Are prefabricated.
Used as a temporary restoration material.
Are thin and donot absorb x-ray radiation, as much as amalgam or gold.
Not as densely radiopaque as amalgam or gold.
Not contoured well near CEJ.
Appear thin or see through on dental x-ray.
Donot appear to fit the tooth well.
15. PORCELAIN RESTORATIONS
Appear radiopaque ; vary in radiographic appearance depending upon whether
restoration is all porcelain or PFM style restoration.
All porcelain crowns and bridges: slightly radiopaque with thin radiopaque line
outlining the prepared tooth; the thin line is the dental cement or adhesive
material; Porcelain is a specific type of ceramic.
When someone refers to a ceramic crown- the material is almost definitely
porcelain.
18. Appearance of composite resin material varies on radiograph
depending upon the materials used (which company manufactured
the resin).
Some manufacturers add radiopaque particles to distinguish the
composite resin from a carious lesion.
19. SOME OTHER MATERIALS
BASE MATERIALS:
Includes zinc phosphate cement and zinc eugenol paste.
Used as cavity liners to protect the pulp. (placed in the floor of the
prep)
Afterwards- restorative material is placed over (on top of) based
material.
Appears radiopaque.
21. When large part of the tooth’s crown is lost.
Due to- progression of dental decay or tooth trauma.
Required when inadequate amount of sound tooth tissue left to
retain a conventional crown.
Tooth must have had root canal treatment.
Purpose of the core: Improve crown retention.
Purpose of the post: retain the core.
Cont….
23. • Restores normal shape, size and function of tooth.
• Can make the tooth stronger or improve the looks.
• If the cavity is too large for a filling and large
fracture.
Crown
(cover or cap)
• Parts: abutment and pontic tooth.
• Abutment teeth: two or more crowns that go over the
natural teeth.
• Pontic tooth: a false tooth. Made from gold, alloys.
Porcelain or a combination.
Bridge (closes a gap created
by one or more missing
teeth, supported by natural
teeth or implants.)
• Thin tooth colored shells.
• Attached to the facial surface of teeth to improve
their appearance.
• Made from porcelain or resin composite material.
• Permanently bonded to teeth
Veneer
26. TYPES OF BRIDGES
Traditional bridge
Most common type of dental bridge
because of their strength and durability.
These involve two dental crowns on
either side of the gap and one, two, or
three prosthetic teeth that are suspended
in the gap. The crowns are anchored to
the two teeth on either side of the gap to
keep the bridge secured.
27. Cantilever bridge
This type of dental bridge is
made up of only one dental
crown and can replace up to
three missing teeth.
It isn’t as strong as a traditional
dental bridge.
28. Maryland bridge
Instead of dental crowns, Maryland
dental bridges have wings on either
side of the prosthetic teeth.
Weakest type of dental bridge, but
patients often choose this option
because the process of placing the
bridge takes less time, is less invasive,
and less painful than the other types
of bridges.
29. Implant supported bridge
Many dentists recommend and prefer
implant-supported dental bridges over
all other choices. Mainly because they
are the most supportive and longest-
lasting dental bridge option.
Unlike the other options, implant-
supported dental bridges utilize dental
implants instead of crowns. The
implants are inserted into the jawbone
through the gums and cause the
jawbone to regrow.
This type of dental bridge will likely
last more than 25 years.
