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

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.

49. Simple SuturesSimple Sutures
Simple interruptedSimple interrupted
stitchstitch
Single stitches,
individually knotted
(keep all knots on one
side of wound)
Used for
uncomplicated
laceration repair and
wound closure

51. Mattress SuturesMattress Sutures
Horizontal mattressHorizontal mattress
stitchstitch
Provides added strength
in fascial closure; also
used in calloused skin
(e.g. palms and soles)
Two-step stitch:
Simple stitch made
Needle reversed and 2nd
simple stitch made
adjacent to first (same
size bite as first stitch)
52. Mattress SuturesMattress Sutures
Vertical mattressVertical mattress
stitchstitch
Affords precise
approximation of skin
edges with eversion
Two-step stitch:
Simple stitch made –
“far, far” relative to
wound edge (large bite)
Needle reversed and
2nd simple stitch made
inside first – “near,
near” (small bite)

55. Bone Graft Materials :
Definition :
‘A graft is a viable tissue that
after removal from a donor site is
implanted within the host tissue
which is then restored, repaired
or regenerated.’
GRAFT
SOFT TISSUE GRAFT BONE GRAFT COMPOSITE GRAFT
www.indiandentalacademy.com
56. Bone graft materials support bone
growth by :
Osteogenesis :
– Direct formation through osteoblasts
Osteoinduction :
– Transformation of mesenchymal cells to
osteoblasts
Osteoconduction :
– Stimulation of attachment, migration &
distribution of vascular & osteogenic cells
www.indiandentalacademy.com
58. Kazanjian’s rules : (1952)
Adequate blood supply of recipient site
Bone to bone contact – ‘ creeping
substitution’
Rigid fixation
Bone graft to be placed in healthy tissue
www.indiandentalacademy.com
59. BONE GRAFTS are used —
Management of non union & delayed
union
Filling of osseous defects
Replacement of bone & joint loss
Augmentation of skeletal deficiency
Fusion of growth plate cartilages
www.indiandentalacademy.com
60. Ideal requirements of bone grafts:
Biologically acceptable
Predictability
Clinical feasibility
Minimal operative hazards
Minimal post-operative sequelae
Patient acceptance
www.indiandentalacademy.com
61. Classification of bone grafts
BASED ON ---
1.ORIGIN
- autograft
- allograft
- xenograft
- bone substitute material
www.indiandentalacademy.com
63. Autografts :
defined as tissue transplanted from one
site to another within the same individual.
considered as gold standard
ADVANTAGES:
No immunologic sequelae
Rapid technique
Disadvantages :
insufficient amount
cortical bone is obtained
www.indiandentalacademy.com
64. Osseous coagulum : (Robinson)
Bone dust + blood mixture
Uses particles from cortical bone
Bone blend:
Bone dust + Saline
Bone used is cortical & cancellous
www.indiandentalacademy.com
65. Areas for obtaining bone grafts
Head & neck
Cranium
Mandible
Thorax
Ribs
Scapula
Forearm
Lower limb
Hip (Iliac crest)
Tibia
Fibula
2nd
metatarsal www.indiandentalacademy.com
66. Allografts : Defined as a tissue graft between
individuals of same species (i.e.,humans) but
of non-identical genetic composition
Cadavers are common source
Allograft
Fresh frozen Freeze dried bone
Decalcified freeze
dried bone
www.indiandentalacademy.com
67. FRESH FROZEN
- Harvested under sterile condition
- kept frozen at -80—does not undergo enzymatic
destruction
FREEZE DRIED (lyphophylized) bone (FDB)
- Mainly used as a composite
- bending strength is lowered to 55-90%
- retain its antigenicity
DECALCIFIED FREEZE DRIED BONE (DFDB)
- retains its osteoinductiveness
Treated with radiations, freezing & chemicals
www.indiandentalacademy.com
68. Advantages :
Sufficient quantity can be obtained
Bone banks
Can be stored at room temperature
Disadvantages :
Difficulty in finding donor
Risk of disease transmission
Immunological reaction
Sophisticated lab procedureswww.indiandentalacademy.com
69. XENOGRAFT-- defined as a tissue
graft between two different species
Examples :
- Kiel bone
- Frozen calf bone
- Freeze dried calf bone
- Decalcified Ox bone
- Ospurum
- Anorganic bone
- Boplant
www.indiandentalacademy.com
70. Alloplasts / non- bone graft materials:
Examples :
- POP
- cartilage
- sclera of eye
- collagen material
Ceramic or synthetic bone grafts:
Resorbable
– Tricalium phosphate, resorbable hydroxyapatite
Non-resorbable
– Dense HA. Porous HA, Bioglasswww.indiandentalacademy.com
