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.

Model Attribute Check Company Auto PropertyCeline George
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.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

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.
2. The Mesoderm
• The mesoderm lies between the
ectoderm and endoderm
• Its cells are divided into three parts:
• Paraxial
• Intermediate
• Lateral Plate
• The paraxial mesoderm is just
lateral to the the notochord
• It gives rise to the vertebrae,
skeletal muscles, and connective
tissue of the skin
3. Regions
• The regions of the trunk and head mesoderm are as follows:
• The central region of trunk mesoderm is the chordamesoderm (axial mesoderm). This
tissue makes the notochord and part of the vertebrate disks.
• The paraxial (somatic) mesoderm is on both sides of the notochord. This will eventually
produce muscle and connective tissue of the back (like parts of the vertebrae, muscles,
etc.)
• Part of the paraxial mesoderm also produce the head mesoderm- skeleton, muscle,
and connective tissue of the skull
• The intermediate mesoderm is lateral to the paraxial- urogenital system (kidneys, gonads)
• Lateral plate mesoderm- Most lateral. It will help form the heart, blood vessels, pelvis
and limb skeleton
4. Cell Types of the
Somite
• Somites are condensations of paraxial mesoderm. They
can be divided into dermomyotomes and sclerotomes
• Dermomyotomes are divided into:
• Dermatomes are the more superficial. They will
become the dermis of the skin of the back.
• Myotomes will from the muscles of the back,
rib cage, and ventral body wall
• Sclerotomes form the vertebrae and rib cage.
5. Establishing the Paraxial Mesoderm and Cell
Fates Along the Anterior-Posterior Axis
• Where the types of mesoderm are in relation to being medial or lateral depends on concentrations of BMP.
• Lateral areas have higher concentrations of BMP
• There is more Noggin towards the notochord. Noggin inhibits BMP
• As far as the anterior-posterior axis, there are many opposing morphogens.
• Towards the posterior is FGF8 and Wnt3a.
• On the anterior portion is Retinoic acid, which represses FGF8
• Hox genes determine what particular structures will form in’ each segment along the anterior-posterior axis.
6. Somitogenesis (somitomeres)
• Somitomeres are going to appear before somites
• The cranial paraxial mesoderm faintly clumps into block-like structures on each side of the
midline
• They appear sequentially starting from the cranial region
• The clumping process is called segmentation
• After the first forms, the next immediately forms caudally to it (until it reaches seven pairs)
• In segmentation, mesenchymal mesoderm is converted back to epithelial tissue
7. Somites
• After the first seven pairs of somitomeres form, the first pair of somites form
• Somites have a more pronounced segmentation.
8. How are Somites Built?
• Mesodermal cella at the caudal end make high levels of FGF8 and Wnt (these inhibit
somite formation)
• These genes need to be shut off in the presomitic tissue
• How to turn off FGF8 and Wnt? The most recent pair of somites will make retinoic acid
and release it into the presomatic tissue. This turns FGF8 and Wnt off
9. Clock-Wavefront Model
• Retinoic Acid is high in the segmenting cells while FGF and Wnt are high in the
proliferating cells.
• As the new somites are formed sequentially (and caudally), it is live a wave.
• Notch gene also has to get turned on in the presomitic tissue
• Notch produces two transcription factors which cause somite development:
• Lunatic fringe
• C-Hairy
• A barrier needs to form between each somite. For this they use Ephrin B
10. Sclerotome
Development
• This is the first large division of the somite
• When the somite is formed, two signaling
molecules form the notochord and neural
tube
• Shh and Noggin
• Shh and Noggin will turn on Pax1 and Pax9
• Pax 1 and Pax 9 will convert the epithelial
tissue back into mesenchymal tissue (it was
previous converted into epithelial tissue)
• They are now sclerotome cells which will go
on to make the vertebrae and ribs
11. Dermomyotome
• Sclerotomes are made with the medial ½ of the somite
• Dermomyotomes are made with the dorsolateral ½ of the somite
• The neural tube and ectoderm secrete Wnt
• Wnt turns on Pax3 and Pax 7
• Pax 3 and Pax 7 transform epithelial mesoderm to mesenchymal cells (except for the tissue in the
center)
• This new mesenchymal + epithelial center is now dermomyotome
