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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

by Scrapping the epidermal layer, leaving the skeleton of veins.
The skeletonized leaf may dry up
Then, the larvae move to other leaves and feed by making small holes.
In later stages, they consume most of these leaf tissues and because of severe attack,
only the stem and side shoots will be standing in the field without any leaf or bolls.
Once squares, flowers and bolls develop, they prefer these better than leaves.
They bore into them, feed on the internal content completely and cause shedding
of squares and young bolls

The damage to cotton starts when plants are young and
are about three weeks old.
The grubs bite into the region between the bark
and the main stem feed on soft tissues, resulting in
swellings on the stem just above the ground level.
Young plants are invariably killed on account of the attack of the pest and the
older plants that survive, lack of vigour and strength, and when strong winds
blow, these plants break at the nodes.
19. Stem gall Stem galls Grub

Affected stem
26. Cotton mite :Tetranychus urticae
( Tetranychidae : Acarina )
Adult mite Eggs
T. urticae is the most numerous mite species on cotton
Other species that may occur are
Bean spider mite
Strawberry spider mite
27. The mites lives under web on the upper surface / lower surface of the
leaves by sucking sap.
The grown up leaves suffer more as a result affected leaves
turn brown and dry up.
28. Nature of damage
The first sign of damage is bronzing of the upper leaf surface near the
petiole or leaf fold
As the numbers increase, the leaves turn red and become in the webbing
and affected leaves may dry and fall off
High mite populations can significantly affect yield and quality of cotton
The earlier in the season that infestations develop the greater the
potential of yield loss and quality decreases
Affected leaves turn brown and later dry up
29. The woolly mites : 1. Aceria gossypii
(Eriophyidae : Acarina )
This is commonly found infesting the herbaceum variety of cotton in Gurjat,
MH and Karnataka
The mite lives under the epidermis of the leaves and causes irritation
resulting in the growth of dense whitish hairs on both sides of the leaves
The infested leaves become stunted, crinkled, hard and crisp and in severe
cases of attack shedding of bolls
2. Aceria putturudriahi
It occurs in Karnataka and induces felt like out growths of white hairs
on tender cotton shoots including squares and leaves
Attacked plants may become stunted with boll formation suppressed
Management practices
Mite infestations increase after the application of some broad- spectrum insecticides
for control of other pests
Control of weeds with in fields and along field boundaries that serve as over wintering
sites for mites
Spray the crop with dicofol @ 2.5ml/ lit. of water or propargite @ 2 ml / lit. of water
30. Indentification of Insect pests of Sunnhemp and
their damage symptoms
Sunn hemp is one of the most important fibre crop, next only to cotton and jute

32. Larva : Caterpillar hairy with brown head and yellow lines on the
dorsal, dorso-lateral side with black stripes and orange patches
Body has long brownish hairs arising on warts. L.P : 18-21 days
Pupa : Pupation takes place either in the leaf folds or in the soil.
The life cycle is completed in about 5 weeks and a number of
generations are completed in a year. P.P : 6-8 days
Nature of damage
The hatching larva either defoliates during vegetative stage and
the caterpillars feed by thrusting the head in to the pod and the rest
of the body exposed and feed on the seed thus cause a decrease in
seed production
Symptoms
Defoliation of plants
Bored seed capsules
33. 2. Hairy caterpillar: Argina cribraria / Argina syringa
(Arctiidae: Lepidoptera)
A. A. cribraria adult has black spots on yellowish wings whereas

Larva : Caterpillar hairy with black transverse markings and white spots.
Pupa : It pupates on the plant or the surface of the soil.
Larvae feed on the leaves and cause defoliation.
Control measures
Larval parasitoids - Bracon brevicornis suppress the population naturally
The pest can be suppressed by hand picking and killing the caterpillars
Foliar spray with methyl parathion @ 2 ml / lit. of water
or
dusting methyl parathion 2 % D @ 10-12 kgs / acre are the effective measures
34. 3. Sunhemp mirid/capsid: Ragmus importunitas
(Miridae : Hemíptera)
This is a small, active, green coloured bug, which sucks plant sap
and when present in large swarms, causes appreciable damage
The pest is widely distributed in Southern India
35. Life cycle of the pest
Eggs : The bugs lay white cylindrical eggs singly in the plant tissue,
generally under the surface layer of leaves
Nymphs : The young nymphs on emergence, begin to feed on the plants
All the stages of the insect may be found simultaneously
When the population is high and attack severe, the plant become pale
and appear unhealthy
Damage symptoms
Nymphs and adults suck the sap from tender leaves and shoots
Minute chlorotic spots, later coalesce to cause yellowing of leaves
In severe attack, cause death of plants
Control measures
The population of the pest can be suppressed by collecting the bugs
with nets or sticky traps
Spray the crop with 625 ml of malathion 50EC in 625 lit. of
water per ha.

(Aleyrodidae: Hemiptera)
Adult is a minute insect with yellow body covered with a white
waxy bloom.
Damage symptoms
Nymphs and adults suck the sap from the under surface of leaves.
Severe infestation results in premature defoliation, development of
sooty mould,
