The human heart is a conical-shaped muscular organ located in the chest that pumps blood through the blood vessels using rhythmic contractions and relaxations. It has four chambers - two upper atria and two lower ventricles - separated by valves that ensure blood flows in only one direction. The heart's main function is to pump deoxygenated blood to the lungs and oxygenated blood throughout the rest of the body to supply all organs and tissues with nutrients and oxygen. Common heart diseases include coronary heart disease, high blood pressure, heart attacks, and ischemic heart disease, which can often be managed through lifestyle changes like diet and exercise or medical treatment if needed.

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.

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.

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.
2. HEART:
• Heart is a pumping organ that keeps the blood continuously
moving in the blood vessels.
• It is a blunt conical organ of about 12cm long and 9 cm broad.
• Its narrow apex is pointed downward and to the left.
• Heart is enclosed in a doubled walled sac, called pericardium.
3. HOW THE HEART BEATS:
• Before each beat, your heart fills with blood.
• The heart muscle then contracts.
• When it contracts it squeezes along the blood
4. THE HEART’S JOB:
• To pump blood throughout your body.
• It does this by:
• Pumping deoxygenated blood from your body to your lungs,
• Pumping oxygenated blood to from your lungs to your body
5. LOCATION OF HEART:
• Our heart is located in the front of our chest. It sits slightly
behind and to the left of our sternum (breastbone). Our
ribcage protects our heart.
6. LAYERS OF HEART WALL:
• Three layers of tissue form the heart wall.
• The outer layer of the heart wall is the epicardium,
• the middle layer is the myocardium,
• and the inner layer is the endocardium.
7. STRUCTURE OF HEART:
• The heart is made up of four chambers: The two upper chambers
are known as the left atrium and right atrium and two lower
chambers called the left and right ventricles.
• It is also made up of four valves: the tricuspid, pulmonary, mitral
and aortic valves.
8. CHAMBERS OF HEART
• The two atria are thin-walled chambers that receive blood from the veins.
• The two ventricles are thick-walled chambers that forcefully pump blood out of the heart.
• Ventricles have thick walled than atria because ventricles have to pump out the blood
with force to the different parts of the body.
• Left ventricles are far thicker walled than right ventricles as it is pumping the blood to
different parts of the body a right ventricle is only up to lungs
9. VALVES OF HEART:
• The right auricle and right ventricle guarded by tricuspid valves.
• The left atrium and left ventricle are guarded by bicuspid (Mitral) valve.
• The valve between the right ventricle and pulmonary trunk is the pulmonary semilunar
valve.
• The valve between the left ventricle and the aorta is the aortic semilunar valve.
• Valves allows only unidirectional flow of blood.
10. FLOW OF BLOOD:
• From right atrium the deoxygenated blood enters the right ventricle
through tricuspid valves.
• From right ventricle the deoxygenated bloods pumped out through
pulmonary artery to lungs for oxygenation.
• Oxygenated blood from left atrium enters the left ventricles through
bicuspid valve.
• From left ventricle, the oxygenated blood is pumped out into aorta.
• Aorta is the largest artery which takes the blood to the body.
11. LUB-DUB SOUND OF HEART:
• A healthy heart makes a lub-dub sound with each beat.
• The first sound (the lub) happens when the mitral and tricuspid
valves close.
• The next sound (the dub) happens when the aortic and
pulmonary valves close after the blood has been squeezed out
of the heart
12. FUNCTIONS OF HEART:
• It pumps blood throughout your body, controls your heart rate and maintains blood
pressure.
• Your heart is a bit like a house. It has walls, rooms, doors, plumbing and an electrical
system.
• All the parts of your heart work together to keep blood flowing and send nutrients to your
other organs.
13. FACTS ABOUT THE HEART:
• Heart is really a muscle.
• Heart Beats between 60 to 100 times per minute
• Heart beats 1,00,000 times a day
• 35 million beats in year
• 2.5 billion approx. in life-time
• Moves 2,000 gallons of blood each day.
• FUNNY BUT TRUE:-
More than studies or biological processes Heart is
Involved in LOVE talks..
14. DISEASES OF THE HEART:
• Coronary Heart Disease, also known as CHD, is the most common of
all the heart-related problems. It’s caused by your arteries getting
smaller which leads to your heart not getting enough blood supply.
High blood pressure High blood pressure, also known as
hypertension, is a common thing that effects about 50 millions
Americans and countless others worldwide. Once again, it’s generally
caused by fatty foods. The best thing to do is try to avoid stressful
situations as often as possible.
15. CONTINUED:
• A heart attack is victim are usually elderly or people the intake of
greasy , fatty foods and don’t exercise.
• Also, people that are understand stress may get heart attack.
• Ischemic heart disease Ischemic heart disease is the opposite of
hypertension, in that it is the reduced flow of blood to the heart.
• The main symptom involved with ischemic heart disease is the
concurrent feeling of chest pain, especially pain in the left side of the
chest (around the heart)
16. TREATMENT OPTION:
• Better diet for Heart Health
• Exercise
• Change Lifestyle
• Heart Disease Medications
• Medical procedures or surgery
• Heart defect patients can have a heart transplant
if there is no other option.
