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.
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.
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

1. CLEFT LIP AND PALATE AND
ITS MANAGEMENT IN
ORTHODONTICS
2. Introduction
• Clefts of the lip and or palate unfortunately, are by far
the most common major facial malformations in
mankind. Fortunately, as a result of technical
advancements in the fields of medicine and their
families for treatment, much can be done and achieved
for them.
• The orthodontist, by virtue of having gained in depth
knowledge of the craniofacial complex, it’s growth
and development, and expertise in tooth movement,
has to play a role of prime importance in making
critical decisions, planning treatment and rendering
care to these patients.
3. INCIDENCE

17. FACIAL GROWTH IN CLP CASES
Prenatal Growth
• Over maxillary segment on non cleft side
- Pull of lip & cheek muscles
- Tongue pressure
- Relatively unstrained nasal septum growth
• Over maxillary segment on the cleft side.
- Intrinsic deficiency
- Presence from alas base due to stretching of the nostril
18. In compel unilat CLP
cases:
- Large maxillary segment
on non deft side thorns a
scare deviation of the
midline away from the cleft
- Smaller maxillary
segment retro positioned /
collapse / prohibition
- Nose toward normal side
- Ala grow in deformed
matrix
In Bilat CLP cases:
- Primarily tilts forward /
shifts one side due to
tongue procure
- Smaller maxillary
segments cither side
similar growth pattern as
in
• Due to above forces the defects produced in CLP basics are
19. FACIAL GROWTH IN UNREPAIRED CLP
- A functionally normal facial skeleton develops in unpaired cases
- Presence pf local bony defect due to intrinsic deficiency in the humiliate
area of the cleft
- Absence normal lip pressure abnormal development of dento alveolar
process can occur
- Mestre et al 1960 Ortiz monarteri et al 1961 & Birhona 1976 fond no
significant difference in overall size with normal adults in un-operated clefts
- Biohara 1973 found retro poritional maxilla & mandible than normal but no
significant differences in any parameters b/co operated & unoperated cases.
- Localized growth defects in un-operated subjects, region immediate to cleft
o alveolar arch defects occurred particularly in lateral & vertical growth at the
region of the alveolar cleft.
- STARK 1968 – A deficiency of mesodermal tissue rather than a more

c) Early mixed dentition treatment (7-9yrs) –after
during eruption of maxillary permanent incisors
d) Late mixed permanent dentition treatment (9 12
yrs on words)
28. PRE- DENTAL
• Initiated by Mc NEIL 1954 and developed by Burstone
1958
• Advantages of this appliance
- To facilitate feeding
- To help in psychological boost to the parents
- To assist the surgeon in his initial repairs
- To stimulate palatal growth
- To restore the oro-facial ‘functional matrix’
- To help in reducing ear infections
- To expand or prevent collapsed segment
- To reduce the need for later orthodontic treatment
- To guide tooth eruption
- To improve esthetics
- To re-establish proper sutural growth patterns early.
29. IMPRESSION
• Extend into the nasal chamber undercut
• Custom trays are preferred
• Posterior limit – up to maxillary puberosity
• Fabrication of a combination soft and hard acrylic passive
maxillary orthopedic appliance
OBTURATOR
• Placement of the appliance and surgical closure of the lip.
This is usually at 10 days to 2 weeks autogenous alveolar
bone graft.
• Stabilization of the graft 2 months or so, using the orthopedic
appliance as a splint.
OBTURATOR -USES
• It facilitates lip repair
• It facilitates the feeding
• It prevents the collapse of the palatal segments
31. METHODS OF PRE SURGICAL ALIGNMENT
• Discussed in two aspects
I. Control of maxillary elements
• Achieve upper arch form which confirms to that of
lower arch
• Stabilization of the arch can be achieved by simple
upper appliance
• Expansion of the upper arch can be achieved by
screw appliance or pre-expanded appliance
• Retention of above appliances by the force of the turn
and the lower jaw, the extra orally ‘whiskers’ are
facilitate handling of appliance
32. A. In bilateral clefts the displaced premaxilla is readapted to confirm to the
arch
B. In unilateral clefts the displaced greater segment is readapted to
conform to the arch
33. II. Control of Pre-maxillary elements
Both unilateral and bilateral clefts extra-oral strapping across
the pre maxilla, attached either directly to the face
Retrusion of the pre-maxilla can only be achieved at the
extends of distortion of the nasal septum.
All these procedure should be done with in 3 months
Huddart 1974 found that use of an intra – oral appliance
restricted further widening of the maxillary arch allowed
normal growth to proceed at margins of cleft.
36. PRIMARY BONE GRAFTING
• Objective – It is to make good the hard tissue
deficiency
• Good surgical grafting improve the oral contours
improved function
Advantages claimed
a) Prevention of collapse of anterior portion of arch
b) Allowing eruption of teeth into the graft site
c) Allow mid line adjustment that is so necessary
to minimize the asymmetry of treated cleft lip
and palate.
37. PRIMARY DENTITION PHASE
• Common problems encountered
a) Cross bite of incisor or buccal teeth
b) A functional shift of the mandible
c) An oronasal fistula
d) Premaxillary protrusion in bilateral clefts
• Expansion fixed maxillary lingual arch
appliance either W-arch or an Arnold expander
• Anterior cross bites a removable inclined plane
on lower incisors or maxillary Hewley retainer
with finger spring. Supernumerary teeth should
be extracted
38. MIXED DENTION PHASE
• Problems are more severe a short period
& effective of orthodontic treatment
a) Sagittal deficiency of the maxilla,
b) Anterior cross bite
c) Downward rotation of the maxillary plane
d) Function deviation of the Mandible
e) Missing teeth
f) Dental crowding
40. Protraction headgear – 5 – 8 yrs, acrylic maxillary
splint with occlusal coverage, cemented on
maxillary teeth with heavy elastics.
500g forces, 10o
to occlusal plane, for 14-16hrs day
for 6 to 12 months.
Leads remodeling changes in the anterior maxilla and
a backward rotation of the mandible.
Contra indicated in mandibular prognatism and high
mandibular plane cases.
41. OTHER AUXILIARY APPLIANCES
Cross bite central incisor
• Negative overjet and maxillary incisor rotations
are corrected simultaneously by lower bite planes,
removable appliance with Z-spring are used.
Maxillary contraction (Transverse / buccal cross
bite)
• Expansion of the maxillary arch by :
– Quad Helix appliance 036 blue engiloy provides
controlled force appliance
– NiTi palatal expanders effect maxillary expansion more
dentoalveolar than skeletal effects.
43. LINGUAL RETAINERS
Open end of U shape retainer facing posteriorly-
located canine and premolar area.
Uses of semi fixed and lingual sheaths type designs
have 4 advantages –
1. Adjustments / replacement easy
2. Transition from expansion to retention is
immediate
3. Avoid interference during bone grafting
4. Allows rapid replacement with easy secondary
design.
45. Functional deviation of the Mandible
Occurs due to interference of incisors
Correction of incisors cross bite and
expansion of the maxillary arch invariably
permit to the mandible to achieve a normal
path of closure
46. Missing Teeth
- Most common in 2 2 next to the
cleft followed by second bicuspids I
both the arches and maxillary third
molars
- Retainers replacing missing teeth
should be worn until permanent
dentition treatment
47. Dental crowding
Because of the incisors retruction arch length is often
reduced I both the arches
A class III tendency man require an oven greater retruction
of the mandibular incisors to establish normal overjet. Serial
extraction is the mode of treatment
If should be also noted that the class III elastics are usually
worn in permanent dentition so that if first biocuspids have
been removed space closure in the mandibular arch may be
difficult to accomplish without excessive lingual tipping of
the mandibular incisors.
48. Alveolar Bone Grafting
Indicated-
To stabilize the premaxilla,
to close oronasal fistula and anterior palatal clefts
To ensure better periodontal support for the erupting
teeth and the teeth burdening the cleft,
to build up the piriform rim and alar base symmetric
with the normal side,
To lend sup[port to the depressed lip[ over the cleft]
To provide bony continuity in the alveolous for
eruption and orthodontic movement of the teeth
adjacent to the cleft in their optimal positions.
49. -Cancellous iliac crest grafts done between
9 and 11 years of age allow quite favorable
eruption of the maxillary canine through
the graft either by itself or by prthodontic
mechantotherapy, with the best possible
periodontal support to be expected.
-Secondary bone grafts or greater
acceptance than the primary bone grafting
50. Permanent dentition
- Most difficult case of treatment
- In case analysis three considerations must be stressed
a. Stability of teeth and maxillary segment
b. Facial esthetics
c. Preparation for a prosthetics
Surgical procedures which are particularly traumatic
which must be assessed on an individual basis and
treatment must be planned accordingly
Problems includes,
a. Vertical jaw relations
b. Jaw relation
c. Lateral jaw relations and dental irregularities
51. Vertical jaw relations
Freeway space is atmost important treating this
problems this excess free way space can be
corrected by
a. Vertical elastics
b. Vertical development plate – used for both open
bite closure which is usually in cuspid region and
forced eruption of all maxillary teeth
c. Mandibular acrylic bite opening plate in
conjunction with vertical elastics – Best method,
because the plate covers mandibular incisors and
provides lingual rest for maxillary incisors
52. Anterio –Posterior jaw relations
- This directly related to the freeway space, so that the
A-P must be made with the mandible in rest position
- A-P relations in females is known to stabilize at
13-14 years where as in males it is 17-18 years. So
stable results may not be achieved until this age
Surgery for severe A-P discrepancy cases
- May be advised if large excess freeway and
mandibular over closure
-Maxillary advancement – preferred in case of mid face
deficiency
-Surgery to be delayed until puberatal growth spurt. 14
years for females and 17 years for males
-Beginning of orthodontic treatment will be after
surgery
53. Lateral Jaw relationships
Expansion should be overdone in order to maintain for
several years with a palatal retainers
Dental irregularities
Teeth frequently crupt in the palate (because of surgery).
Lateral cuspids are commonly involved in which case
retention of these teeth after may be alignment may be
difficult particularly, if the root apex is palatably placed.
Serial extraction often it is indicated it is
satisfactory to remove one or more mandibular incisors
to relieve crowding, this makes treatment much simpler
and co-ordination to mandibular incisors is less critical
in cleft cases
54. Surgery
Time of surgery is quite a contraoversy
Different according to different school
of thought generally,
Cleft lip- 3-6months
Cleft palate – 1 1/2 – 2years
Most surgeons follows the rule of 10-
-10 weeks of age
-Weight 10pounds
-Hb 10%
-WBC should be lesser than 10,000
55. Cleft lip surgical repair
-Various methods of CL repair aimed
to lengthening the philithral ridge on
the cleft side to correct the nose
deformaties have much as possible
-The lip is closed in three layers –
mucosa, muscles,skin
- Most favorable surgical operations
are Millerd’s rotations advancement
flap, Tennison Randal repair, Veau
repair
56. Millard’s Repair of CL
Millard’s rotation flap (a) and Columella flap(c) or planned
medial side of the cleft . After full thickness of the lip cut
along the markings a rotation gap is produced on the medial
side which is filled by an advancement flap(b) planned on
the lateral side of the cleft
57. Tennison Randall repairs
• A triangular flap is created on the lateral side of the cleft to
fit in to the triangular defect produced on the medial side
of the cleft. This procedure can be planned exactly after
initially measurements. The results cannot be modified
once the lip is cut. The scar is more prominent than in
other procedures.
58. Veau repair
It is the simplest one stage straight line
closure and produces satisfactory results u a
bilateral cleft lip. In this method vermilion
flap from either lateral side of the cleft is
brought down over the prolabium to augment
the vermilion I the centre of the upper lip
61. 3. Veu Wardill Kilner V-Y
push back palatoplasty
Cleft palate repair by a double
opposing Z- plasty of Furlow
is relatively new procedure
aimed are reducing the
midfacial growth retradation
problem. However more
experience is required with
this procedure before reaching
any conclusion
62. Distraction Osteogenesis
- This technique is Increasing popular and has a good
potential for severe maxillofacial deformities, where in
a bone segments are lengthened by using intra oral,
extra oral devices
- Maxillary distraction for CLP cases has been shown
to be particularly useful when the maxilla to moved
forward enlarged distance, which by orthognathic
surgery alone may not be technique feasible or stable.
Since this technique involves fixing of considerable
hardware on the cranium for a few months, the choice
is restricted to select cases having a large maxillary
retraction
63. Relapse and retention
CLP cases requires long term if not permanent retention for the
following reasons:
• In adequate bone support
• Absence of some teeth
• Presence of stretched scar tissue
- For this reason, retention, the orthodontist’s final frontier
must be planned in detail
Retainers of choice
i. Soldered lingual retainers
ii. Hawley’s retainers with Pontiac to replace missing tooth
iii. Bonded spiral wire retainers for derotated incisors
64. CONCLUSION
The course of the individual CLP patients ’s
rehabilization depends not only on the quality of
the individual components of the treatment, but
also on organization and co-ordination to ensure
the right timing, sequence and balance during
the often protruded course of treatment. For this
reason, a well adapted CLP protocol, with a
collectively operating inter disciplinary rather
than multidisciplinary approach to provide
integrated cleft care seems to be absolutely
imperative.
65. The myriad manifestation of the
malocclusion typical in Cleft lip and palate
necessities a harmonious medley of a multitude of
mechanotherapy procedures that emancipates the
orthodontist from the monotonous momentum of
mundane tooth moving procedures. CLP
rehabiltative treatment is the privilege and real
reward. In that endeavourer, our responsibilities go
beyond orthodontics. We can always go further;
we can always work harder; we can always find
newer possibilities; but for that we must keep
going and doing
