The 1991 Bangladesh cyclone was one of the deadliest tropical cyclones on record, killing at least 138,000 people. It made landfall in Bangladesh on April 29, 1991 as a Category 4 cyclone with winds of 155 mph, causing a storm surge of 20 feet. This led to widespread flooding and destruction of over 1 million homes, leaving 10 million people homeless. The cyclone caused $1.5 billion in damages and significant loss of life, especially among children and the elderly. International relief efforts helped provide aid to around 2 million people affected by the disaster.

Tropical cyclones—variously defined as hurricanes, typhoons, and cyclones—regularly impact human populations and periodically produce devastating weather-related natural disasters. The destructive forces of cyclonic winds, inundating rains, and storm surge are frequently accompanied by floods, tornadoes, and landslides.

A Strategic Approach: GenAI in EducationPeter 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.

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.

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.

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.

1991 North Indian Ocean cyclone season
The 1991 Bangladesh cyclone (IMD designation:BOB 01, JTWC designation:02B) was among
the deadliest tropical cyclones on record. On the night of 29 April 1991 a powerful tropical
cyclone struck the Chittagong district of southeastern Bangladesh with winds of around
250 km/h (155 mph). The storm forced a 6 metre (20 ft) storm surge inland over a wide area,
killing at least 138,000 people and leaving as many as 10 million homeless.
2. [edit] Meteorological history
Storm path
An area of persistent cloudiness, in part due to the monsoon trough, developed into a tropical
depression on April 22 in the Bay of Bengal. The wind speed and overall size increased, with the
depression becoming Tropical Storm 02B on the 24th. The enormous wind field at the time
encompassed nearly the entire bay.
The tropical storm continued slowly northwestward, slowly strengthening to a cyclone-strength
storm on the 27th. The cyclone moved between a high pressure system to its northwest and east,
and as mid-level westerlies met up with the storm, the cyclone moved northeastward. The
westerlies enhanced upper level outflow, and in combination with warm water temperatures the
cyclone steadily strengthened to a major hurricane on the 28th.
On the 28th and 29th, as the system increased its speed to the north-northeast, the cyclone
rapidly intensified to a 160 mph Cyclone, the equivalent to a Category 5 hurricane. Late on the
29th, Cyclone 02B made landfall a short distance south of Chittagong as a slightly weaker
155 mph Category 4 Cyclone. The storm rapidly weakened over land, and dissipated on the 30th
over southeast Asia.

[edit] Fatalities
Flooding around a river in Bangladesh
At least 138,000 people were killed by the storm,[1] with the majority of deaths in the Chittagong
area. Most deaths were from drowning, with the highest mortality among children and the
elderly. Although cyclone shelters had been built after the 1970 Bhola cyclone, many had just a
few hours of warning and did not know where to go for shelter. Others who knew about the
storm refused to evacuate because they did not believe the storm would be as bad as forecast.
Even so it is estimated over 2 million people did evacuate from the most dangerous areas,
possibly mitigating the disaster substantially.
[edit] Property damage

3. The storm caused an estimated $1.5 billion (1991 US dollars) in damage. The high velocity wind
and the storm surge devastated the coastline. Although a concrete levee was in place near the
mouth of the Karnaphuli River in Patenga, it was washed away by the storm surge. The cyclone
uprooted a 100-ton crane from the Port of Chittagong, and smashed it on the Karnaphuli River
Bridge, effectively breaking it into two partitions. A large number of boats and smaller ships ran
aground. Bangladesh Navy and Bangladesh Air Force, both of which had bases in Chittagong,
were also heavily hit. The Isha Khan Naval Base at Patenga was flooded, with heavy damages to
the ships. Most of the fighter planes belonging to the air force were damaged. Approximately
1 million homes were destroyed, leaving about 10 million people (a substantial portion of
Bangladesh's population) homeless.
[edit] Environmental impact
The storm surge subsequently caused the embankment, as well as whole villages, to be swept
away. For an additional three to four weeks after the storm had dissipated, mass land erosion
resulted in more and more farmers losing their land, and therefore, the number of unemployed
rose.[2]
[edit] International response

The United States amphibious task-force, consisting of 15 ships and 2,500 men, returning to the
US after the Gulf War was diverted to the Bay of Bengal. This was part of Operation Sea Angel,
one of the largest military disaster relief efforts ever carried out, with the United Kingdom,
China, India, Pakistan and Japan also participating.[1]
Operation Sea Angel began on May 10, 1991 when President Bush directed the US military to
provide humanitarian assistance. A Contingency Joint Task Force under the command of
Lieutenant General Henry C. Stackpole, consisting of over 7,000 US soldiers, was subsequently
sent to Bangladesh to provide food, water, and medical care to nearly two million people. The
efforts of U.S. troops, which included 3,000 tons of supplies, are credited with having saved as
many as 200,000 lives.[3]
