This document provides information on the chemical elements plutonium, mercury, fluorine, lead, chlorine, arsenic, tin, iodine, uranium, sulfur. For each element, it summarizes their health effects if absorbed in excess, symptoms of exposure, and common industrial or household usages. The information seeks to educate on the dangers of exposure to these elements and how they can negatively impact organ function, health, and in severe cases cause death if proper safety precautions are not followed in their production or usage.

The Impact of Test Case Summaries on Bug Fixing Performance: An Empirical Inv...Sebastiano Panichella
Automated test generation tools have been widely investigated
with the goal of reducing the cost of testing activities.
However, generated tests have been shown not to help developers in detecting and finding more bugs even though
they reach higher structural coverage compared to manual
testing. The main reason is that generated tests are di-
cult to understand and maintain. Our paper proposes an
approach, coined TestDescriber, which automatically generates
test case summaries of the portion of code exercised by
each individual test, thereby improving understandability.
We argue that this approach can complement the current
techniques around automated unit test generation or search based techniques designed to generate a possibly minimal set
of test cases. In evaluating our approach we found that (1)
developers find twice as many bugs, and (2) test case summaries
significantly improve the comprehensibility of test
cases, which is considered particularly useful by developers.

Wish u a very happy diwali .....
this is a ppt on diwali
it will help you for ur presentaions
it can be used for corporate and school level
displaying...
thankyou
hoped u like this
Toxicity is a function of solubility. Insoluble compounds as well as the metallic forms often exhibit negligible toxicity. The toxicity of any metal depends on its ligands. Heavy metal toxicity can result in damaged or reduced mental and central nervous function, lower energy levels, and damage to blood composition, lungs, kidneys, liver, and other vital organs.
A molecule not consisting of carbon atoms.
Any molecule that is not considered organic, or not of biological origin.
Inorganics include salts, metals, substances made from single elements and any other compounds that don't contain carbon bonded to hydrogen.
table salt or sodium chloride, NaCl.
carbon dioxide, CO2.
Humans are exposed to these metals by ingestion (drinking or eating) or inhalation (breathing).
Working in or living near an industrial site which utilizes these metals and their compounds increases ones risk of exposure.

Marco Paz
2. Plutonium (Pu)
The radiation from even a small amount of plutonium
dust inhaled into your lungs will give you lung cancer.
Can affect the ability to resist disease and may cause
reproductive failure.
Usage:
A dangerous key fissile element that has been
used in explosives for a long time.
3. Mercury (Hg)
When absorbed into the blood and distributed to all
tissues including the brain it will rapidly contaminate the
passes through the placenta to the fetus and will have fetal
damage.
People will have paresthesia that will result to stumbling,
slurred speech, constricted visual fields, and impaired
hearing.
Sooner the person will have tremors and jerks, followed by
coma and death.
Usage:
An element used in thermometers to
determine the temperature.
4. Fluorine (F)
Essential for the maintenance of solidity of our bones.
When absorbed too frequently, it can cause teeth
decay, osteoporosis and harm to kidneys, bones,
nerves and muscles.
Can cause death at very high concentrations. At low
concentrations it causes eye and nose irritations.
Usage:
An element used in
making toothpastes.
5. Lead (Pb)
When too much exposure is done it may cause nerve
disorders, decreasing IQ, Decreasing muscle and bone
growth, kidney failures and Hypertension.
If it circulates the blood vomiting, diarrhea,
convulsions, comma and death will occure.
Usage:
An element used in making
automobile batteries and paint.
6. Chlorine (Cl)
When absorbed it can react with the lungs to generate
hydrochloric acid. Hydrochloric acid is corrosive and can
damage the lungs, which may later cause death.
Long term exposure may also cause irritation of eyes or
blindness. It has strong oxidizing powers, making it
harmful on skin, and internal organs.
Usage:
An element used in purifying water and used as a
bleaching agent in household laundry.
7. Arsenic (As)
Exposure to inorganic arsenic can cause various health
effects, such as irritation of the stomach and
intestines, decreased production of red and white
blood cells, skin changes and lung irritation.
People who drunk water with arsenic can cause
diarrhea, leukonychia, and convulsions.
When it goes to the heart you may have a cancer,
stroke, respiratory diseases and diabetes.
Usage:
An element used for insecticides.
8. Tin (Sn)
Excessive exposure of Tin will damage your breathing,
urination and immune system.
The symptoms when you have a Tin exposure is that
your eyes and skin is irritated, severe sweating,
decreasing number of red blood cells and depression.
Usage:
An element used in making cans for industrial purposes.
9. Iodine (I)
Too much Iodine consumption will lead you to weight
loss, heartbeat failure and kidney problems.
When it goes through your body the nervous system
will work more and your metabolism gets high.
You will have a thyroid related diseases that will defect
some of the human organs.
Usage:
An element that is used in
making your table salt.
10. Uranium (U)
When high level of uranium is in your body you can
have respiratory failure.
This chemical goes through the blood and kills the
kidney cells.
Cancer of the kidney and cancer of the lung will start if
you emit too much uranium toxics.
Usage:
An element used in making
the armor of tanks, bullets and missiles.
11. Sulfur (S)
A human body needs sulfur to get the proteins we
need every day. But when you over use it you will have
a disturbance in blood circulation, reproductive
failure, hearing defects and blindness.
You can also have a problem when breathing, stomach
disorder, behavioral changes when you get too much
sulfur.
Usage:
An element used in black
gunpowder and fireworks.
