swine flu

A great fear is there in the mind of people of India. i would like to tell you in elaborated manner about SWINE FLU.
H1N1 is caused by a new influenza virus that causes illness in people. Genetic studies have shown that the viral strain is an amalgamation of genetic materials from at least three viruses affecting humans, birds and pigs, and hence is feared to be deadly.
why is it called H1N1 virus?
Influenza A virus are named on the basis of two characteristic prteins found on the surface of the virus- haemaggluttin(H) and neuraminidase(N).
why is it so dangerous?
Public health experts are worried that this virus has the potential of becoming a global killer.
from a mere 38 cases 20 were from the US.the virus has spread to 74 countries.
as it spread from pork and pork a simple question is that whether
should you eat pork or not?
Although the virus originated in pigs, it is not known to move to people through pork and related products that are consumed. And flu viruses are not known to survive cooking temperature 70-80*C.
How do people become infected with H1N1 flu virus?
outbreaks in humans are now occurring from human to human transmission. when infected people cough or sneeze, infected droplets get on their hands and nearby surfaces and are dispersed into the air. people who breathe in this contaminated air becomes susceptible.Hence people should cover their face or bear mask in infected area.
what are the signs and symptoms of swine flu?
Early signs of influenza A(H1N1) are flu-like, including fever, cough, headache, muscle and joint pain, sore throat and runny nose, and sometimes vomiting or diarrhoea.
Is there any effective vaccine against the new virus?
No, but work on such a vaccine is underway. Making vaccine for a completely new variety of influenza can take five to six months.
How serious is it in India?
India is the last country to have reported H1N1 infections. Till june 12, there are 16 confirmed H1N1 flu cases in India. Most of them contracted the infection while travelling abroad.The cases involving kin of the infected indicate that human-to-human transmission is taking place in India too.

graphene manufaturing

How much do you think about graphene? how much do you know about graphene?
To know all these answers go toknow more about graphene .my another blog where i have posted detail of graphene.As i am also an engineer. i could see a great material that will rock the computer world on very large scale is graphene. graphene is going to make your processor of your computer that will make it too much faster.
i am going to tell you how it is getting manufactured these days?
you might be knowing this fact that Indium is manufactured by evaporation method. In this method raw indium is heated in a vacuum vessel and above the surface a nickel sheet is placed. The material get accumulated on the surface thus now we can get it from that surface. Though this technique was used to make graphene. In a vessel it graphite was heated at high temperature and could accumulate graphene on nickel. But they could not separate it from nickel.
Byung Hee Hong at Sungkyunkwan University in Seoul, South Korea, and colleagues could applied the technique to produce films of up to 12 sheets on extremely thin pieces of nickel.

They dissolved the nickel with chemicals after formation of thin layer of graphene on it.when nickel thin film was dissolved in chemical they were left with thin film of graphene. Graphene that was obtained could maintain their striking electronic properties even when bent and twisted.
Widespread availability of larger and high-quality graphene films will surely vastly speed up research into the material's properties. it will lead to a promised development in material science.

You might have heard a lot of about graphene.i will tell you a lot about graphene in this post.Graphene is an allotropes of carbon like diamond and graphite.Graphene is the most famous material in research world.Graphene will make our computer fastest.Graphene's transistor will replace silicon from our computer.Graphene is a single layer of carbon atoms.The nanotubes that is created by double layer of graphene is also an allotopes of carbon.
Graphene was discoverd by Professor Andre Geim's team.Graphene is commercially little more available. if you want to know a lot abot graphene then go to the link below.Lear a lot about graphene here

one step to sustain on earth

Save this world
Darwin had given this theory that there is always struggle for existence.Even now in this world a lot of struggle is going on. Animals are struggling to survive and apart from that each and every human being is trying to survive. To survive on earth each and every one is killing this environment day per day. we are degrading the environment where do we live. On which we struggle to survive. If nature will not be there then we can't even struggle to survive.So to save this Natural world we are supposed to come forward to save it, on world environment day. For this kind work our government has come forward and indian government has put a ministry of it called Ministry of New and Renewable Energy. .Dr. Faruq Abdullah is currently minister of this department.
We people can get a lot of benefit from this department. Actually this department is distributing all sustainable resources of energy and it's equipment at a subsidy for it's citizen in india. you can go to it's website ministry of new and renewable energy resource
you will get a lot of information on how to get such products. where you can get in the locality of your state or even your district. what is needed is your initiative and nothing more than that. There are lot of products available there which is totally suitable for you at home. you can reduce your electricity bill to a great extent. And apart from that you are doing a kind work not for us but for you SON . Don't you love him? ya you must but love him another way as well so that he and his further generation could survive with pleasure on earth.
