A letter to Bill Gates from santa singh


Dear Mr. Bill Gates,

This letter is from Banta Singh from Punjab. We have bought a computer
for our home and we found problems, which I want to bring to your

1. After connecting to internet we planned to open e-mail account and
whenever we fill the form in Hotmail in the password column, only ******
appears, but in the rest of the fields whatever we typed appears, but
we face this problem only in password field. We checked with hardware
vendor Santa Singh and he said that there is no problem in keyboard.
Because of this we open the e-mail account with password *****. I
request you to check this as we ourselves do not know what the password is.

2. We are unable to enter anything after we click the 'shut down '

3. There is a button 'start' but there is no "stop" button. We request
you to check this.

4. We find there is 'Run' in the menu. One of my friend clicked 'run '
has ran upto Amritsar! So, we request you to change that to "sit", so
that we can click that by sitting.

5. One doubt is that any 're-scooter' available in system? As I find
only 're-cycle', but I own a scooter at my home.

6. There is 'Find' button but it is not working properly. My wife lost
the door key and we tried a lot for tracing the key with this ' find',
but unable to trace. Is it a bug??

7. Every night I am not sleeping as I have to protect my 'mouse' from
CAT, So I suggest u to provide one DOG to kill that cat.

8. Please confirm when u are going to give me money for winning
'HEARTS' (playing cards in games) and when are u coming to my home to collect
ur money.

9. My child learnt 'Microsoft word' now he wants to learn 'Microsoft
sentence', so when u will provide that?

Foods That Boost Your Health

There is evidence that our brain responds to the foods we eat, and that nutrients can trigger neurotransmitters and hormones that impact our mood and improve our mental sharpness. Not only has this been shown in children at school, but studies have also found that adults can help maintain brain health as they age.
The way things are going, I don’t anticipate a break until at least Thanksgiving. So until then, here’s what I’m focusing on during this grueling work-a-thon.

Brains are very hungry

The brain and nervous system are the hungriest organs—meaning that they require a constant supply of energy that can only be delivered in the form of glucose, the end product of carbohydrate metabolism. The brain uses more than 20 times the energy ounce-per-ounce of exercising muscle than any other part of the body; in fact, as we age, it’s the natural loss of gray matter that makes a significant contribution to our drop in metabolism.

What this means is that breakfast is very important, and so is eating every two to three hours throughout the day. The constant stream of glucose to the brain will help keep your concentration and mood elevated. A meal or snack that contains low-glycemic carbohydrates, or combines carbs with lean protein and/or some healthy mono or polyunsaturated fats, will help keep the fuel to the brain steady.

Eat a slow-burn breakfast

Reams of research show that kids who eat a healthy breakfast have improved concentration, and they perform better on tests compared to those that skips out on the a.m. meal. I’m no student, but I do know that eating my low-glycemic steel-cut oats gives me energy to start the day and raises my blood-sugar levels that have plummeted overnight. Other studies have found that a breakfast of low-glycemic-index foods like oatmeal increased mental acuity over high-glycemic-index breakfasts with the same number of same calories.

Eggs with a whole-wheat product—toast are great option to boost brainpower. Eggs contain choline, which helps the body make the memory-boosting chemical acetylcholine.

Eat more fruits and veggies

You’re probably aware of studies showing that blueberries improve the memory and cognitive function of aged animals, but all fruits and veggies are great cerebral choices. In addition to providing carbs to fuel the brain, they supply folic acid, a B-vitamin integral for the nervous system. In addition, they’re loaded with powerful antioxidants that help keep the blood vessels of the brain healthy and more flexible so that the brain gets adequately nourished.
I’m making more of my snacks fresh or dried fruits and veggies. Today I had raisins in my oatmeal, a banana with peanut butter at lunch, and a spinach salad with my dinner.

Enjoy caffeine and tea

affeine has been shown to improve concentration in studies, and tea has also been shown to have a compound, L-thiamine that impacts alpha waves in the brain. Alpha waves are supposed to help the brain focus when it is bombarded with all kinds of competing tasks (read: nonstop emails and phone calls). The combination of L-thiamine and caffeine in tea is akin to rebooting my mind to help me focus on finishing one task at a time, instead of being completely frazzled by a long to-do list all day.

Be a (healthy) fat head

Yes, your brain is a muscle, but about 70% of its gray and white matter is composed of fat. And it’s not just any fat; it’s the long-chain polyunsaturated fats that are part of the cell membranes and crucial messenger system of the brain.
These beneficial fats are called DHA and EPA, and you can find them in fish and algae-based supplements. Research shows that adults who eat the most tuna and other fish rich in DHA have healthier brain mass as they age, compared to those who eat the least amount of fish. But there’s one caveat: Interestingly, fried fish consumption does not provide the same brain-boosting benefits.

Make mental moves

nothing goes better with a healthy diet than a healthy lifestyle. To keep the blood and nutrients flowing to your brain, strive to get daily exercise. Exercise also clears your mind, gives you a natural endorphin rush, and staves off depression. Research also shows that among older adults, those who exercise the most have better cognition and improved mental states compared to those who move the least.

The Green Chemistry

What is Green Chemistry?

The Green Chemistry is defined as invention, design, development and application of chemical products and processes to reduce or to eliminate the use and generation of substances hazardous to human health and environment. While this short definition appears straightforward, it marks a significant departure from the manner in which environmental issues have been considered or ignored in the upfront design of the molecules and molecular transformations that are at the heart of the chemical enterprise.

Looking at the definition of green chemistry, the first thing one sees is the concept of invention and design. By requiring that the impacts of chemical products and chemical processes are included as design criteria, the definition of green chemistry inextricably links hazard considerations to performance criteria.

Another aspect of the definition of green chemistry is found in the phrase “use and generation”. Rather than focusing only on those undesirable substances that might be inadvertently produced in a process, green chemistry also includes all substances that are part of the process.

Therefore, green chemistry is a tool not only for minimizing the negative impact of those procedures aimed at optimizing efficiency, although clearly both impact minimization and process optimization are legitimate and complementary objectives of the subject.

Green chemistry, however, also recognizes that there are significant consequences to the use of hazardous substances, ranging from regulatory, handling and transport, and liability issues, to name a few. To limit the definition to deal with waste only, would be to address only part of the problem.

Principles of Green Chemistry

The twelve principles of green chemistry embrace these aims, as well as those of waste prevention, the use of renewable raw materials, the minimization of derivatives and better control of chemical processes. The Royal Society of Chemistry has established the Green Chemistry Network to promote green chemistry and now publishes a journal, Green Chemistry , devoted to the subject.

1) It is better to prevent waste than to treat or clean up waste after it is formed.
2) Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
3) Wherever practicable, synthetic methodologies should be designed to use and generate substances that posses little or no toxicity to human health and the environment.
4) Chemical products should be designed to preserve efficacy of function while reducing toxicity.
5) The use of auxiliary substances (e.g. solvents, separation agents etc.) should be made unnecessary wherever possible and, innocuous when used.
6) Energy requirements should be recognized for their environmental and economic impacts and should be minimized. Synthetic methods should be conducted at ambient temperature and pressure.
7) A raw material feedstock should be renewable rather than depleting whenever technically and economically practical.
8) Unnecessary derivatization (blocking group, protection/deprotection, and temporary modification of physical/chemical processes) should be avoided whenever possible.
9) Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.
10) Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products.
11) Analytical methodologies need to be further developed to allow for real-time in-process monitoring and control prior to the formation of hazardous substances.
12) Substances and the forms of the substance used in chemical reaction should be chosen so as to minimize the potential of chemical accidents, including releases, explosions, and fires.

Doctor's Medical Certificate

Doctor's Medical Certificate

Doctor Certified

i Certified that Mr. /Miss ________________ _ , working in your organization, is suffering from 'time-bound' illness.

Due to this, he/she will NOT be able to work more than 8 hours a day and 5 days a week.

Any attempt to stretch beyond this timing will lead to severe health problems.

The losses to the company due to medical reimbursements will be far more compared to the gains made by stretching beyond 8 hours.

It is also warned to keep my patient away from any kind of shocking news such as " Come over weekend..", " Let's work on holiday..", " Leave cannot be granted. ." etc.

which can directly lead to heart strokes.

In view of the above, it is strongly recommended to adjust your deadlines in accordance with the convenience of my patient.

Anusat : The Anna University Microsatellite

ANUSAT is a 50 kg micro satellite being designed and fabricated at Anna University, Chennai. The aim is to bring university based academicians and research and development experts of ISRO together to implement a project in university environment. ANUSAT carries a digital store and forward payload for amateur communication. In addition, a number of technological payloads like digital receiver and turbo coder and MEMS based gyro and magnetic field sensor are planned to be in this micro satellite. During the year, the configuration of this satellite has been finalised and breadboard/design verification models of the core electronic systems completed.

ANUSAT, A micro-satellite designed and being built by Anna University at a cost of Rs.5.5 crores. The Indian Space Research Organisation (ISRO), sponsor of the project, would decide the launch of the micro-satellite.This collaboration is the first of its kind in India. Mr Rajaram Nagappa, a fellow MITian, former ISRO scientist and the Chief of Centre for Aerospace Research, MIT is the key interface person between the ISRO experts and the academic community.

Students and Professors from various departments have been actively involved in this project for almost an year now. At present various subsystems of power electronic systems, the BUS electronic and RF systems have been developed.

ISRO's Polar Satellite Launch Vehicle(PSLV) at Sriharikota has launched the micro-satellite, first of such satellite to be built by any university in the country. Dr. Jayaraman said Anusat would have a "store and forward" payload. The control centre would be on the Madras Institute of Technology campus while three ground stations would be located in Bangalore, Guwahati and Pune.

Know About Swine Flu

What is swine flu??

It is a lot like our seasonal flu but it usually only affects pigs. This one, swine influenza A (H1N1), is affecting humans who have not been exposed to pigs. This suggests there might be human-to-human transmission. The mode of transmission is presumably respiratory droplets.

The swine H1N1 is very different from the human H1N1 that is in the flu vaccine. Currently there is no human vaccine available for swine flu.


Symptoms are very similar to the human flu:

•Sore throat
•Fatigue/Body aches
•Decreased appetite
•Less commonly: runny nose, nausea, vomiting, diarrhea


Similar preventions as the seasonal flu. Try to avoid being exposed to respiratory droplets.

•Hand washing or use of alcohol-based hand sanitizers (minimum concentration of 60 percent to 95 percent ethanol or isopropanol).
•Avoid touching your eyes, nose and mouth as those are direct entry points for viruses. Viruses can get on your hands when you touch infected objects.
•Avoid close contact (6ft) with a sick person.


Tamiflu and Relenza (both prescription medications) work on this virus but it needs to be started in the first 48 hours of symptoms. So it is important to contact your doctor right away if you have symptoms.

If I think I have the flu, what should I do?

STAY HOME and contact your physician right away. This is not the time to be "tough" and go into work or school nor is it the time to travel. If you see your doctor, they might do a swab of your nose or mouth to confirm the virus . Your doctor would start you on treatment based on your symptoms and likelihood of having the illness. Don't be alarmed if your doctor's office has a sign posted, like in the SARS days, that tells you to put on a mask if you have flu-like symptoms. This is a routine precaution during an outbreak to protect health care workers as well as other patients in the office.

COVER YOUR COUGH and avoid close contact with others. You should maintain a distance of 6 ft between you and other people, even family members. If you need to COUGH or SNEEZE, cover it with a tissue and throw the tissue away. Alternatively if you have no tissue available, you can cough or sneeze into the elbow of your sleeve. You are trying to avoid spreading infected respiratory droplets around that others could pick up.

There is no reason to panic your doctor can handle the situation.

Eyes are Precious

They open windows to the world and soul...

1.Eyes are the most complex organs you possess except for your brain.


2.Eyes are composed of more than two million working parts.


3.Eyes can process 36,000 bits of information every hour.


4.Under EXTRAORDINARY conditions, some can discern the light of a candle at a distance of 14 miles.


5.Eyes contribute towards 85% of your total knowledge.


6.Eyes utilize 65% of all the pathways to the brain.


7.Eyes can instantaneously set in motion hundreds of muscles and organs in your body.


8.In a normal life-span, will bring you almost 24 million images of the world around you.


9.The external muscles that move the eyes are the strongest muscles in the human body for the job that they have to do. They are 100 times more powerful than they need to be.


10.The adult eyeball measures about 1 inch (2.5 cm) in diameter. Of its total surface area only one-sixth is exposed -- the front portion.


11.The eye is the only part of the human body that can function at 100% ability at any moment, day or night, without rest. Your eyelids need rest, the external muscles of your eyes need rest, the lubrication of your eyes requires replenishment, but your eyes themselves "never" need rest. But please rest them!


12.Eyes are your most precious sense... cares for them properly!
