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.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
2. Astigmatism is a common vision condition that
causes blurred vision. It occurs when the cornea
(the clear front cover of the eye) is irregularly
shaped or sometimes because of the curvature of
the lens inside the eye.
3.
4.
5. It is an error of refraction in which the parallel rays
of light from infinity can not coverage to a point
focus due to unequal refraction in differrent
meridians of the optical system of the eye ,but form
focal lines.
6. A refractive condition that is the result of two
principal meridians of the eye having different
refractive power.
7. CAUSES OF ASTIGMATISM:-
Astigmatism occurs when the cornea or the lens ,has a
slightly different surface curvature in one direction from
the other.
There is a steep meridian and a flat meridian.
Varying refractive index.
Asymmetry of the cornea, or the lens or the posterior
retina.
Any variation in refractive index.
Tilting of the lens.
Any eye mass lesion.
The weight of the upper eyelid resting on the eyeball
Any healed aberration or injury of the cornea which can
be due to any infection or trauma.
9. 1) Regular astigmatism:-
when the refractgive power
changes uniformly from oone meridian to the other.
2) Irregular astigmatism:-
when the refractive power
changes irregulalry in differrent meridians as seen
in corneal facets.
10. ETIOLOGY OF REGULAR ASTIGMATISM:-
Corneal Astigmatism
Lenticular astigmatism
a. Curvatural
b. Positional
c. Index
Retinal astigmatism
11. TYPES OF REGULAR ASTIGMATISM:-
1) Simple Astigmatism:-
In this,one foacl line falls on the
retina and the other falls either in front of of behind
the retina ,when the eye is at rest.when one focal
line falls in front of the retina the other being formed
on the retina ,the condition is known as simple
myopic astigmatism.
similarly in simple hypermetropic astigmatism one
line is formed behind the retina and other on the
retina.
12.
13.
14. 2) Compound Astigmatism:-
In this ,both the focal lines
are formed either in front of the retina when it is
called compound myopic astigmatism of behind the
retina when it is called compound hypermetropic
astigmatism.
15. 3) Mixed Astigmatism:-
In this one of the focal lines
is formed in front of the retina and the other behind
that structure.
16.
17. SYMPTOMS OF ASTIGMATISM:-
Blurring of vertical , horizontal or diagonal lines
Eyestrain or fatigue
Headaches
Distortion in portions of the visual field
Squinting
