Smog : History, Types, Causes and its Effects zairaakbar
Here's the difference between fog and smog and how the smog is formed. Why smog is formed in winters?
Realtion of Great smog of 1952 and London smog disaster of 1952 with sulfurous and photochemical smog.
Smog is a kind of intense air pollution, originally named for the mixture of smoke and fog in the air. Major cities around the world are experiencing the effects of air pollution.
The changes in the surface air temperature,reffered to as the global temperature, brought about by the enhanced green house effect, which is enduced by emmission of greenhouse gases into the air.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Acid r
1.

5.
Acid rain is a rain or any other form of
precipitation that is unusually acidic, meaning
that it possesses elevated levels of hydrogen
ions.
It can have harmful effects on plants, aquatic
animals and infrastructure.
6.
7. Human activities are the main cause of acid rain.
Over the past few decades, humans have released
so many different chemicals into the air that they
have changed the mix of gases in the atmosphere.
Power plants release the majority of sulfur dioxide
and much of the nitrogen oxides when they
burn fossil fuels, such as coal, to produce
electricity.
In addition, the exhaust from cars, trucks, and
buses releases nitrogen oxides and sulfur dioxide
into the air. These pollutants cause acid rain.
12. Normal unpolluted rain water is only slightly
acidic because. This is because it contains
carbonic acid. The carbon dioxide naturally
present in the air is dissolved in rain water.
Unpolluted rain water has a pH of about 5.6.
The carbon dioxide present in traces in
UNPOLLUTED AIR dissolves in rain water
forming weak carbonic acid[H2CO3].
13.
14. Acid rain refers to rain[or any precipitation i.e.
snow or fog] which has pH less than 5.6.
Since it is mainly caused by atmospheric
pollutants like sulphur dioxide and nitrogen
oxides , it is a complex mixture of sulphuric
acid [H2SO4]nitric acid [HNO3] (and
sulphurous[H2SO3] and nitrous [HNO2] acids)
15. ELECTRIC POWER STATIONS BURN COAL[fossil fuel] FOR
POWER GENERATION.
1.
Sulphur [S] impurities in the coal-form pollutant sulphur
dioxide [SO2]
S + O2SO2
2.
Sulphur dioxide [SO2] reacts with water vapour to form
sulphurous acid[H2SO3] H2O+SO2=H2SO3 [aq.]
3.
Sulphur dioxide [SO2] can also be oxidised to sulphur
trioxide[SO3] 2SO2 +O2=2SO3
[The reaction catalysed by dust particles and water droplets]
4.
Sulphur trioxide [SO3]reacts with water vapour in air forming
sulphuric acid [H2SO4]
5.
H2O +SO=H2SO4[aq.]
6.
Thus the acidity in rain is due to reaction of oxides of sulphur
with water vapour forming dilute acids
16. Nitrogen in air at temperature above 1300
degree Celsius combines with oxygen to form
nitrogen monoxide .
The high temperature can be achieved
during Natural Sources - Lighting Bolts
Human Source - Combustion of Gasoline in
Automobiles.
25.
Several regions in the U.S. were identified as
containing many of the surface waters sensitive to
acidification. They include
◦ the Adirondacks and Catskill Mountains in New York state,
◦ the mid-Appalachian highlands along the east coast,
◦ the upper Midwest, and mountainous areas of the Western
United States.
◦ In areas like the Northeastern United States, where soil
buffering capacity is poor, some lakes now have a pH value of
less than 5. One of the most acidic lakes reported is Little
Echo Pond in Franklin, New York. Little Echo Pond has a pH of
4.2.
25
27.
Acid rain and the dry deposition of acidic
particles contribute to the corrosion of metals
(such as bronze) and the deterioration of paint
and stone (such as marble and limestone).
These effects seriously reduce the value to
society of buildings, bridges, cultural objects
(such as statues, monuments, and
tombstones), and cars

28. An example of acid precipitation damage to an outdoor statue. The statue, made of porous sandstone, was created in 1702 as
part of the gable of the entrance of the Castle at Herten, near Reclinhausen, Germany. The left photo, taken in 1908, shows
some stains and the loss of the left hand, but most of the face and right hand were intact after 206 years of exposure. The
right photo, taken in 1969, shows the loss of most of the detail of the statue over 61 years

Sulfates and nitrates
that form in the
atmosphere from sulfur
dioxide (SO2) and
nitrogen oxides (NOx)
emissions contribute to
visibility
impairment, meaning we
can't see as far or as
clearly through the air.
Sulfate particles
account for 50 to 70
percent of the visibility
reduction

Elevated levels of fine
particles increase
illness and premature
death from heart and
lung disorders, such as
asthma and bronchitis.
reducing the nitrogen
oxides available to
react with volatile
organic compounds and
form ozone

31.
Turn off lights, computers, and other appliances when you're
not using them
Use energy efficient appliances: lighting, air
conditioners, heaters, refrigerators, washing machines, etc.
Only use electric appliances when you need them.
Keep your thermostat at 68 F in the winter and 72 F in the
summer. You can turn it even lower in the winter and higher in
the summer when you are away from home.
Insulate your home as best you can.
Carpool, use public transportation, or better yet, walk or bicycle
whenever possible
Buy vehicles with low NOx emissions, and maintain all vehicles
well.
31
32.
EPA's Acid Rain Program limits, or "caps,"
sulfur dioxide (SO2) emissions from power
plants at 8.95 million tons annually, allows those
plants to trade SO2 allowances, and reduces
nitrogen oxide emission rates.
32
33.
34. A catalytic convertor in internal combustion
engines- helps reduce pollution.
The reduction catalyst in a converter
separates the nitrogen atom from NO and
NO2 molecules freeing oxygen in the form of
O2 molecule.
Thus the oxides of nitrogen which are
pollutants are converted to free nitrogen.
