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.

4. Splitting and cleaningSplitting and cleaning
The fish is split and the gut,gills are
removed
Then they are cleaned with water
5. SaltingSalting
The cleaned fish is then soaked in
brine solution
Duration of treatment with brine
depends up on the strength of the
brine solution
The brine is stored at a temperature
of 52 to 55 degree C and is changed
atleast once a day
6. HangingHanging
The salted fish is hung in the kiln on
a rack for dipping
The protein which has dissolved in
the salt form a sticky solution on the
surface of the fish
Which gives the skin a glossy
appearance which is one of the
commercial criteria of the quality
8. The Hot Smoking ProcessThe Hot Smoking Process
The smoking time will vary as well depending
on the size of the fish and the conditions for
the marketing of the products but will usually
be 1-2 hours.
The fish is dried for a period before smoking
in order to prepare the skin for the reception
of the smoke
The fish could be lightly salted or not be
salted at all before smoking, sometimes a
sprinkle of salt is given when packed in boxes
after smoking
9. The equipment for the hot smoking
process has developed from the most
simple chimney/barrel to specially
designed cabinets with inbuilt devises
for the control of the smoking process
but it is characteristic that the very
primitive equipment persists.
10. During cooking process it loosesits
weight
If the fish is packed hot it may
develop a moist,flabby appearance
sand mould growth may occur
11.
12. The Cold Smoking ProcessThe Cold Smoking Process
The characteristic feature for cold smoked
fish will be that the flesh does not appear
cooked
Most cold smoked fish are smoked as fillets
The fish could be exposed to smoke for an
extended period of 24 hours or more in a
smoking cabinet
However the time is shortened considerably
in the modern cold smoking process to
approach the times known from the hot
smoking process.
13. Freezing of fishFreezing of fish
Freezing extends the period of storage
and effective in keeping the fish in a
condition similar to the resh fish
Three methods:
1.By direct contact between the fish and
a refrigerated metal plates
2.By blowing a continuous stream of
refrigerated air over the product
3.By immersing the fish in a low
temperature liquid
14.
15. Dried fishDried fish
The fish is prepared immediately after
capture
After gutting the fish, it is either dried
whole, or split along the spine leaving the
tail connected.
Stable cool weather protects the fish from
insects and prevents bacterial growth.
Too much frost will spoil the fish, as ice
destroys the fibers in the fish.
16. After its three months hanging on the
flakes, the fish is then matured for another
two to three months indoors in a dry and
airy environment
During the drying, about 80% of the water
in the fish disappears
The stockfish retains all the nutrients from
the fresh fish, only concentrated: it is
therefore rich in proteins, vitamins, iron,
and calcium.
20. Requirements Concerning RawRequirements Concerning Raw
MaterialsMaterials
Fish intended for canning should be
produced in accordance with the
appropriate Sections of this code
21. Storage of raw materialStorage of raw material
Raw materials should be stored, as quickly as
possible after reception, in suitable premises
Raw materials should be stored so that any
recontamination of final products, in-process
products or containers should be prevented
All materials for containers or packages should
be stored in satisfactory clean and hygienic
conditions
During loading, stowing and unloading of
empty containers, containers shouldn't be
stepped on. These precautions become more
imperative when cans are put in bags or on
pallets.
22. Unwrapping, UnpackingUnwrapping, Unpacking
During unwrapping and unpacking
operations, precautions should be
taken in order to limit product
contamination and foreign matters
introduction into the product.
To avoid microbial proliferation,
there should be no waiting periods
during these operations.
23. ThawingThawing
Thawing time and temperature should be
selected to avoid conditions favourable
for development of microorganisms or
decomposition
During thawing products should not be
exposed to excessively high temperatures
After thawing should be immediately
processed or refrigerated and kept at the
adequate temperature (temperature of
melting ice).
24. Gutting and WashingGutting and Washing
fish requiring gutting on arrival at the
plant should be gutted efficiently and with
care to avoid contamination
gutting must be complete to remove
pieces of intestinal tract and internal
organs
immediately after gutting, fish should be
washed with clean sea water or potable
water. After washing the fish should be
drained and properly iced
25. Pre-Cooking and Other Pre-Pre-Cooking and Other Pre-
TreatmentsTreatments
There are several reasons for pre-cooking
fish or shellfish prior to canning:
- to lower the water content of the
flesh in order to avoid water exudation
during heat processing
- to give a particular flavour or texture
to the product
- in some cases, to prepare the
products for later treatments.
26. Packing in Cans (Filling,Packing in Cans (Filling,
Sealing and Coding)Sealing and Coding)
Filling
- Containers and covers should be inspected
immediately before delivery to the filling
machines or packing tables to ensure that they
are clean, undamaged and without visible flaws
- Containers of canned fish should be filled
as directed in the scheduled process
- Mechanical or manual filling of containers
should be checked in order to comply with the
filling rate and the headspace specified in the
adopted sterilization schedule
27. The necessary amount of headspace will
depend partly on the nature of the contents.
The filling should also take into account the
heat processing method
If fish has been brine-frozen or stored in
refrigerated brine, the amount of salt
absorbed should be taken into
consideration when salt is added to the
product for flavoring
Excessive vacuum may cause the container
to panel, particularly if the headspace is
large, and may also cause contaminants
28. Filled containers should be
inspected
- to ensure that they have been
properly filled and will meet accepted
standards for weight of contents
- and to verify product quality and
workmanship just before they are
closed.
29. SealingSealing
Sealing the container is one of the most
essential processes in canning
The operation, maintenance, regular
inspection and adjustment of sealing
machines should received particular care.
If vacuum is used during packing, it
should sufficient to prevent the containers
from bulging under any condition likely to
be encountered during the transport,
storage or marketing of the product.
30. This is useful for deep containers or
glass containers.
It is difficult and hardly necessary to
create a vacuum in shallow
containers that have relatively large
flexible covers.
31. Handling of Containers AfterHandling of Containers After
Closure - Waiting Before HeatClosure - Waiting Before Heat
ProcessingProcessing
Containers after closure should always be
handled carefully in such a way as to
prevent every damage capable to
determine defects and microbiological
recontamination
Filled and sealed metal containers should
be thoroughly washed before heat
processing to remove grease, dirt and fish
or shellfish marks on their outside walls
32. the filled and sealed containers must
be held for a long time before heat
processing, refrigeration or heat
holding (> 63°C) for fish soups, for
example, are necessary

34. Labeling, Casing and Storage ofLabeling, Casing and Storage of
Finished ProductsFinished Products
The materials used for labelling and
casing canned fish and shellfish should
not be conducive to corrosion of the
container
Code marks appearing on containers of
canned fish and shellfish should also be
shown on the cases in which they are
packed
Canned fish and shellfish should be so
stored that they will be kept dry and not
exposed to extremes of temperature
