Weapons may rise or might fall the civilization.As weapons give power to destroy enemies and in the same way it dishonors the civilization and humanity.
Weapons may rise or might fall the civilization. The weapons used to destroy enemies are must destroy those which are unarmed and are not the enemies they must be the victim of this.
Thats why the are considered as Mass Destructive Weapons.
Most destructive weapon is the Naval Weapons.
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.
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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

patients may die. About 14% (1 in
7) of all plague cases in the United
States are fatal
• Basic treatment: Early treatment of
pneumonic plague is essential. To
reduce the chance of death,
antibiotics must be given within 24
hours of first symptoms
30.70

• Staphylococcus aureous is the bacteria
that produces Enterotoxin B toxin (food
poisoning)
– Toxin poisoning can be caused after
ingesting contaminated food that looks and
smells ok.
• In 1984 an incident in Oregon saw 751
people poisoned from food at salad bars
after 2 cult members cultivated
Salmonella
30.76

91. Summary
• By using IMS, responders can focus on
the problem-solving process.
• The IC must determine the strategic
goals and tactical objectives that will
begin to stabilize the incident and bring
it to a successful conclusion with the
least amount of harm and damage.
