From a Chinese doctor who was transferred to study coronavirus patients ( from Shenzhen hosital)..

If you have a runny nose and sputum when you have a cold, you cannot be a new type of coronavirus pneumonia, because coronavirus pneumonia is a dry cough without runny nose. This is the simplest way to identify. Please tell your friends that if you know more about medical knowledge, you will have more awareness of identification and prevention. Dean Reference
This time, the Wuhan virus is not heat-resistant and will be killed at a temperature of 26-27 degrees. Therefore, drink more hot water. You can tell your friends and relatives to drink more hot water to prevent it. Go under the Sun. It has been cold recently, and drinking hot water is also very comfortable. It is not a cure and is good for the body. Drinking warm water is effective for all viruses. Try not to drink ice, remember!
Doctor’s advice about coronavirus:

1. It is pretty large in size (cell is about 400-500nm diameter), so any normal mask (not just the N95 feature) should be able to filter it out. However, when someone who’s infected sneezes in front of you, it will take a great 3 meters (about 10 feet) before it drops to the ground and is no longer airborne.

2. When the virus drops on metal surface, it will live for at least 12 hours. So remember if you come in contact with any metal surface, wash your hands with soap thoroughly.

3. The virus can remain active on fabric for 6-12 hours. Normal laundry detergent should kill the virus. For winter clothing that does not require daily washing, you can put it out under the sun to kill the virus.

About the symptoms of the pneumonia caused by Coronavirus:

1. It will first infect the throat, so the throat will have the dry sore throat feeling which will last for 3 to 4 days

2. Then the virus will blend into the nasal fluid and drips into the trachea and enter the lungs, causing pneumonia. This process will take 5 to 6 days.

3. With pneumonia, comes high fever and difficulty in breathing. The nasal congestion is not like the normal kind. You will feel like you are drowning in water. It’s important to go seek immediate medical attention if you feel like this.

About prevention:

1. The most common way of getting infected is by touching things in public, so you must wash your hands frequently. The virus can only live on your hands for 5-10 mins, but a lot can happen in those 5-10 mins (you can rub your eyes or pick your nose unwittingly).

2. Aside from washing your hands frequently, you can gargle with Betadine Sore Throat Gargle to eliminate or minimize the germs while they are still in your throat (before dripping down to your lungs).

Folks, take extra care and drink plenty of water.

Sri Lanka does not possess an entrenched tradition or a history of Opinion Polling as many other developed nations. The Department of Census and Statistics plays the dominant role as the regular survey researcher but it has a state centric origin and is being described as the central statistical agency in Sri Lanka supplying data needed for planning, policy formulation and monitor the progress of various government policies. As a result, it largely caters to the Government and its affiliated institutions.

Sri Lanka is now more efficiently managing the immediate post war refugees in comparison to, say, mid 1999. In this case, the helpless refugees from Vanni and other close-by areas.

The government is making significant progress in this regard since the staggering 300000 (plus) refugee head count in 2009 May in the immediate aftermath of the final battle has now dramatically fallen. According to the Mr M.B.Dissanayake, Secretary of Resettlement Ministry, the refugee population in Nothern relief camps are just 17932 (6896 families-as of first week of November 2010).


Experiments with coal power

As last Sunday’s (24) fire at the construction site of Norochcholai Coal Power Plant (NCPP) began to flash on the news headlines and later when the Police and Government Analysts began to probe the cause of the fire, there was near panic -especially within the power supply sector in the country.

The NCPP and more importantly, coal powered electricity, was suddenly in the spotlight.

The incident was sufficient to invoke panic-considering not only our power supply and demand dynamics-but more.

The main crisis faced by post war Sri Lanka is the power crisis.  At present, hydropower produces 37% of electricity and the deficit of 63% is from fuel. In addition, the power demand increases by 10%  each year.

Sri Lanka’s annual energy generation is around 9800 GWhours. Demand (at peak) is recorded at 1922 MW. Sri Lanka achieved 80% electrification by 2008 and its national energy policy is now geared to raise this to 95% by 2015.


Are you getting this signal?

90% of world population now has mobile network access. And close to a quarter (23%) of the 8.3 billion world population has access to Internet, according to International Telecommunication Union (ITU).

Released on the eve of the first ever World Statistics Day (Wednesday October 20), “The World in 2010: ICT Facts and Figures” by ITU says that 90% of world population now has mobile network access (this, of course, does not mean that 90% ‘own’ a mobile phone-only that they have ‘access’ to mobile networks/coverage). ITU however warns ‘mobile cellular growth is slowing worldwide’. It adds that among the estimated 5.3 billion mobile subscriptions (by end 2010), 72% -that is 3.8 billion- will be from the developing world.  On the other hand, in the developed countries, growth in mobile sector has slowed ‘considerably’ during the past five years.

Data (‘SMSes’), rather than voice services (‘calls’) are leading the growth in mobile services with close to 200,000 text messages being sent every second-over the period of 2007 to end 2010, the global SMS volume stands at a ‘staggering 6.1 trillion’, said ITU. Average cost of an SMS is US $ 0.07 (SL Rs 8.00) and every second, Rs 1.5 million worth SMSes (US $ 14000) transmitted globally.

People are moving rapidly from 2G to 3G platforms, across globally and in 2010, 143 countries were offering 3G  commercially. ITU says that Sweden, Norway, Ukraine and the United States have started to offer services at even higher broadband speeds called as 4G, which is the next generation wireless platform.
