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.

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.

Flood Reservoirs are those which store
water during flood and release it
gradually at a safe rate when flood
reduces
Distributed Reservoir is a small storage
reservoir used for water supply in a city
A multi-purpose reservoir is that which is
designed for
Flood Protection,
Irrigation,
Hydroelectric development,
domestic and industrial supplies
Storage Reservoirs are primarily used for
water supplies for
Irrigation,
Hydroelectric development,
domestic and industrial supplies

1. Study of runoff pattern at the
proposed dam to determine the
storage capacity to a given demand.
2. Determine hydrograph for the worst
flood to determine the spillway
capacity and design
6. Selection of site for Reservoir
1. Low percolation losses in catchment area
2. Quantity of Leakage should be minimum
3. Percolation below dam should be minimum
4. Reservoir basin should have narrow opening
5. Cost of Real Estate should be less
7. Selection of site for Reservoir
6. Less submerging of land & other properties
7. Deep reservoirs are preferred to avoid
evaporation loss and weed growth
8. Silt from tributaries should be minimum
9. Rocks and soils at reservoir must not contain
any objectionable minerals and salts
8. Zones of Storage
1. Useful Storage
2. Surcharge Storage
3. Dead Storage
4. Bank Storage
5. Valley Storage
9. Storage Capacity and Yield
Yield is the amount of water that can be
supplied from reservoir in a specified interval of
time.
1. Safe Yield
2. Secondary Yield
3. Average Yield
Max. quantity of water that can be
guaranteed during a critical dry period
Quantity of water available in excess of
safe yield during periods of high flood
Arithmetic average of safe yield and
secondary yield over a long period of
time
10. Mass Inflow Curve
Mass Inflow Curve is a plot between the
cumulative inflow in the reservoir with time.
Used to find reservoir capacity corresponding
to a specific yield with the help of Demand
Curve
11. Demand Curve
Demand Curve is a plot between the
cumulative demand with time.
Uniform rate of demand curve
Variable rate of demand curve
12. Calculation of Reservoir Capacity
Procedure:
1. Prepare Mass Inflow Curve & Demand Curve
2. Draw tangents parallel to demand curve
3. Measure the max. vertical intercepts
4. Biggest the vertical intercept represents the
required storage capacity
13. Calculation of Safe Yield from Reservoir
Procedure:
1. Prepare the Mass Inflow Curve
2. Draw diagram for various demand rates
3. Draw tangents to specified reservoir capacity
4. Measure the slopes of each tangent. The
Slope of flattest demand line is safe yield
14. Reservoir Sedimentation
River catchments carry silt during heavy rains.
Factors affecting erosion and silt load are
Nature of soil of the catchment area
Topography of the catchment area
Vegetation cover
Intensity of rainfall
Soft soil leads to Sheet Erosion
Hard soils carries less silt Steep slopes give rise to high velocity
High velocity erodes surfaces easily
Higher intensity of rainfall causes greater
runoff and more erosion
If a catchment area has sufficient
vegetation cover the higher velocities are
checked and erosion is very much
reduced.
15. Reservoir Sedimentation
Sediment transported by the river can be
divided into two heads:
1. Bed Load
2. Suspended Load
The bed load is dragged along the bed of
the stream and is about 10 to 15% of
suspended load
The suspended load is kept in
suspension because of the vertical
component of the eddies formed due
friction of flowing water against bed
Density Current is gravity flow of a fluid under another fluid.
Clear water is in upper layer
Muddy or turbid water flows along the channel bottom
towards dam.
16. Life of Reservoir
The useful life of reservoir is terminated when
its capacity is reduced to 20% of the designed
capacity.
This will occur over a time period when the
dead storage is reduced by siltation.
Probable rate of siltation should be considered
in reservoir planning
17. Life of Reservoir
The reservoir sedimentation is measured in
terms of its Trap Efficiency (η)
It is a percent of inflowing sediment which is
retained in reservoir
Measurement of Sediment:
Collect sample from various depths
Filter sample and measure dried silt in
the units of ‘ppm’
18. Example
No. of Years = Reduced Capacity / Annual Sediment Trapped
*Trap Efficiency decreases
with decrease in Capacity-Inflow Ratio
19. If the dam is constructed lower in first
instance and is being raised in stages
increases Life of Reservoir
Sufficient outlets should be provided in
different elevations to discharge flood
water
20. Dams
Dam is a hydraulic structure constructed across
river to store water on its upper stream.
Most common types of Storage Dams:
Rigid Dam: Masonry or Concrete Gravity Dam
Non-Rigid Dam: Earth, Rockfill, Combined
Earth and Rockfill Dam
21.
22. Selection of site for Dam
1. Topography
2. Geology and foundation conditions
3. Availability of construction materials
4. Spillway size and location
5. Reservoir and Catchment Area
23. Selection of Dam
The selection of type of dam is depends on
1. Topography
2. Geology and Foundation Conditions
3. Materials of construction
4. Spillway size and location
Earth dam with a separate spillways
are suitable for low rolling plains.
An Arch dam is suitable for a low
narrow V-shaped valley
If foundation consists of sound rock with no
fault and fissures, any type of can be
constructed
Rocks like Granite, Gneiss and Schist are
suitable for Gravity Dams
Poor rock or gravel foundations are suitable
for Earth dams and Rock fill dams
If sand, gravel and crushed stone is
available, a concrete gravity dam is preferred
If coarse and fine grained soils are
available, an earth dam is suitable
If large spillway capacity is required, overflow
concrete gravity dam is preferable
If small spillway capacity is required, earth dams
are preferable
If large discharge is required, concrete gravity dam
is preferable
If no other site is available for spillway, earth dam
with central overflow section of concrete
24. Selection of Dam
5. Roadway
6. Length and Height of Dam
7. Life of Dam
If a roadway is to be passed over top
of the dam, an earth or gravity dam is
preferred
If length of a dam is very long and its
height is low, an earth dam is preferred
If the length of dam is small but height
is more, gravity dam is preferred
Concrete or masonry gravity dams
have very long life
Earth and Rockfill dams have
intermediate life
