Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
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.
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.

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.

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.

2. Word equations
Chemists often use word equations as a way of quickly
informing us what the reactants and products are in a
reaction.
Reactants: a substance that takes part in and undergoes change during a
reaction
Products: The products are the substances that are formed during
the chemical change.
3. Structuring word equations
Like mathematical equations, chemical word equations are
structured the same throughout the world (this is called a scientific
convention).
- the names of the reactants are always on LEFT
- an arrow (meaning “reacts to give”)
- the names of the products are always on RIGHT
For example:
Magnesium + Copper Oxide Magnesium Oxide + Copper
Steel (Iron) Wool + Copper Sulphate Iron Sulphate + Copper
4. Identifying States of matter
When writing worded equations, it will assist the
reader if you can communicate the state of matter
that the reactants and products are in.
To do this, the scientific convention is as follows:
A solid is identified by a subscript (s)
A liquid is identified by a subscript (l)
A gas is identified by a subscript (g)
An aqueous solution (a substance dissolved in
water) is identified by a subscript (aq)
5. You try
Re-write the following sentences as word
equations:
- Magnesium burned brightly reacting with the
oxygen in the air to form magnesium oxide.
- Hydrochloric acid reacted with the calcium
hydroxide to give water and calcium chloride
- Hydrogen gas and oxygen gas combine to form
water.
6. How did you go?
Re-write the following sentences as word equations:
- Magnesium burned brightly reacting with the oxygen in the air to
form magnesium oxide.
Magnesium + Oxygen Magnesium Oxide
- Hydrochloric acid reacted with the calcium hydroxide to give water
and calcium chloride
Hydrochloric acid + Calcium Hydroxide Water + Calcium Chloride
- Hydrogen gas and oxygen gas combine to form water.
Hydrogen + Oxygen Water
7. Remember!
Feel free to watch this video as many times as you like.
Pause, take notes, rewind if necessary.
Take note of any questions that you have – we will have time in
class to discuss these at length.
In class, rather than taking notes, we will be practicing the skills
covered in this video. We will do this individually, in small
groups, and as a whole class.
