Snorkeling allows one to observe marine life underwater through the use of a mask, snorkel, and fins without needing to constantly resurface for air. It began as early as 900 BC when divers used reeds or animal skins to breathe underwater. Over time, innovations like diving bells, masks, and snorkels were developed to allow easier underwater viewing and breathing. Today, basic snorkeling equipment includes a mask for clear underwater vision, a snorkel for breathing at the surface, fins for efficient swimming, and optional items like rash guards, caps, and defoggers.

Extreme Sports how high-risk subjects performed outdoors are defined; is in contact with nature. There practitioners only want to undergo extreme stress. With it looking a psychic and physical deliverance, giving them a deep sense of pleasure. The harsh environmental conditions found in nature become judge, opponent, even the protagonist of the action.
These sports are characterized by sports in which participants have to undergo a series of challenges which are imposed by other players or to the same field.
Nowadays, millennials are looking for tourist places that provide them with opportunities to explore nature up close while indulging in adventurous activities. This is why of late, snorkeling has become quite popular with people of all age groups. Snorkeling offers you an opportunity to dive underwater and view the magnificence of the underwater world seen never before. Go through the slide to know the things to keep in mind while snorkeling.
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”.

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.

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.

3. One of the best simple way to
see, discover, and appreciate the
intriguing underwater life is
through snorkeling. It allows one
not only to grasp the amazing
beauty of marine life, but swim
with them as well.
4. Snorkeling is peeking through life
underneath water by swimming with the
aid of a snorkel and masks. Through
snorkeling, one can observe the
underwater attractions
period of time, without
for a longer
the need to
constantly resurface to gasp for air, and
with relatively lesser effort.
5. Snorkeling is not only used for
recreational purposes. It has also
been used in water-based search
by rescue teams and in water
sports such as underwater hockey,
underwater rugby, and spear
fishing.
8. Skin divers of the island
Crete in the
Mediterranean used
hollow reeds to breathe
while submerged in
water as they collected
sponges.
9. An ancient bas-relief
dating 900 B.C. depicted
divers in Assyria using
an animal skin filled with
air to lengthen their stay
underwater.
10. Alexander the Great encouraged the
development of the First diving bell, which
was a cauldron designed to trap a pocket of
air when it was lowered into the water. This
instrument allowed divers to take breaths
without needing to go all the way up to the
surface to gulp air, but it also limited their
mobility. On one of the writings of Aristotle,
he mentioned divers using a tube
connected to the surface to the snorkel
remarking that it worked like “the trunk of
the elephant”.
11. The shell of the tortoise was
used to develop a gadget to
protect the eye as well as to see
more clearly in water. The shell
was sliced very thinly until
became translucent then
polished for vision clarity, It was
then used by the Persian divers.
12. Leonardo
created
da Vinci proposed and
the first contemporary
snorkel, a hollow tube designed
attached to the leather-head helmet
of the diver, allowing to breathe even
when face was submerged
underwater. He also had a sketch of
webbed swimming gloves, an idea
that led to the modern-day fins.
13. Benjamin Franklin came
up with an idea of using
wooden paddles attached
to the hands and feet to
help swimmers swim
faster.
16. A. MASK
The mask serves as the
viewing device in appreciating
the world beneath the water.
Without the mask, everything
viewed underwater will be
blurred or distorted. The
airspace created in the mask
is what helps in seeing clearly
underwater.
17. A. MASK
The nose being enclosed in the
mask will have its special function in
equalizing pressure during dives.
Diving underwater brings pressure in
the air space in the mask. In order to
equalize this pressure, one needs to
exhale a little air through the nose,
inside the mask. Otherwise, one might
suffer from “mask squeeze”, a
condition where the soft tissues
beneath the mask, especially around
the eyes, swell and discolor.
19. A. MASK
STRAP – holds the mask to the
faceunderwater
PARTS OF THE MASK
MASK SKIRT – is the soft flexible
material that seals the
mask aroundthelace
NOSE POCKET– cushions and
protects the nose. Some
masks have the purge valve,
a little valve located at the
bottom of nose pocket that
helps in removing the water
that hasenteredthemasks.
20. B. SNORKEL
The snorkel is a piece of
equipment that makes it possible to
breathe at the surface while the face
is submerged in water. It is basically
composed of a tube, also called the
barrel, and mouthpiece. The tube-
end sticks out of the water while the
mouthpiece goes in the mouth. It
also has a clip so it can be attached
to the mask.
22. B. SNORKEL
1. CLASSIC SNORKEL – has the
most basic
solid tube
part, the
and the
mouthpiece.
Sometimes , this can
be bent to a specific
shape.
23. B. SNORKEL
2. SNORKEL WITH A FLEXIBLE TUBE– below
the strap attachment point is
more comfortable than the
classic snorkel. The flexible tube
allows the top and mouthpiece
to rotate to different angles to
better fit the face. It can also
drop away from the face when
not in use.
25. B. SNORKEL
PURGE VALVE – a common
feature of many snorkels.
It is a small valve just
lower than the mouth that
empties the collected water
that comes down the tube
when one blows it out.
26. B. SNORKEL
SPLASH GUARD– a common
feature of many snorkels. It
is a small valve just lower
than the mouth that empties
the collected water that
comes down the tube when
one blows it out.
27. B. SNORKEL
DRY VALVE – is a special valve on
top of the tube that completely
stops water (and air) from
entering the tube when a wave
comes or when diving
underwater. This way, one does
not need to clear the water out
when coming back to the
surface.
28. C. SNORKELINGFINS
Water resists or “pushes back” anything
moving through it. This is the principle behind
what the fins do. It is the resistance that
provides much of the propulsion created by a
moving fin.
Speed and efficiency in swimming are
what one gains in wearing fins. They provide the
necessary locomotion to propel effortlessly in
the water. Fins conserve more energy, and,
therefore , allow the snorkelers to reach further
distances. Moreover, fins may also protect the
feet from accidental contact with rocks and
corals. Treading in water also becomes easy with
fins.
30. C. SNORKELINGFINS
1. Full-foot fins – cover the
heel and are put on like slip-
on shoes. They are easy to
use, more flexible, and
more efficient while
swimming on the surface.
These are more popular
among warm-water dives.
31. C. SNORKELINGFINS
2. Adjustable fins – are open
at the heel and have adjustable
straps to secure the feet. They
are good choices when diving in
cold water, as the boots will
help from getting cold. They
have more rigid blade than the
full-foot fin and they can
provide a more forward thrust
but requires more effort to use.
32. C. SNORKELINGFINS
In recent years, a new
sub-classification has also
developed in both full-foot
and open-heel fins, namely:
1. Conventional fins or paddle-
bladed fins
2. Split fins
33. C. SNORKELINGFINS
1. Paddle-bladed fins– have a
single, full blade.

long,
slow, and powerful strokes of the legs.
It also gives good control and
maneuverability especially when
carefully moving around corals. One
can also use a variety of kicking
strokes with paddle fins.
34. C. SNORKELINGFINS
2. Split fins– are “semi-
parted” in the web,
separating the blade into
two long, stiff blades. It
is easier to kick with split
fins on. These make it
easier for the swimmer to
propel forward.

36. E. SKINPROTECTION
Snorkeling may require one to
be under the sun for some time. In
order to protect the skin from the
heat of the sun, one may use a good
biodegradable sunscreen or a better
choice will be wearing a long sleeve
rash guard. The shirt may also
provide jellyfish sting protection.
However, if insulation is needed
from the cold water, then a wetsuit
will be a better option.
