Breif description of Producer gas plant
The plant which can produce producer gas is called producer gas plant. Producer gas produces by cokeing process, combination of coal and steam in a controlled air.

Chemical reaction
Oxidation Zone:-

The reaction are C + O2 = CO2
Primary Reduction Zone :-

The reaction are : - C + H2O = CO + H2
C + 2H2O = CO2 + 2H2
C + CO2 = 2CO
Secondary reduction Zone

The reaction are

C + CO2 = 2CO
CO + H2O = CO2 + H2

Beside above reaction zone inside the bottom shell, there is an Ash zone under oxidation zone through which calculated quality of air saturated with steam enter and receives heat from the ash which , on the other hand

The distillation zone starts from the top of the bottom shell and extends upwards to above 2500mm or so in which considerable quality of volatile matters (about 85%) is picked up by gas.

At the top there is pre heating and drying zone which starts from the distillation zone and extends to the top of extended shaft as described above.

Bhuvan VS Google earth

Google earth get some competition now from ISRO which today unveiled its beta version of BHUVAN ( meaning earth in Sanskrit). A web based tool like google earth bhuvan promises to give better 3-D satellite imagery of india than in currently beign offered by the us based software gaint plus a host of india-specific feature like weather information and even administrative boundaries of all state and district. The application can be downloaded from


Range :

1) Google Earth : 200 metres

2) Wikimapia : 50 metres

3) Bhuvan : 0 metres

The tool would offer picture of the globe, just like goggle earth and navigable in the same way but currently has best resolution over the Indian sub-continent. It allow user to fly from space, street land, grab, spin & zoom down to any place. It also provide tool for measuring drawing, saving, printing, and visualizing thematic inform. The resolution currently offer are good enough to view a vehicle moving around the road quite clearly. Bhavan currently offer image taken in between one and three year ago even over india. It combine satellite imaginary from various sensor on-board. IRS (Indian remote sensing) satellite and transposes them on a 3-d globe. As it keep updated its databases with more and higher resolution images

H1N1 (swine flu)

This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs (swine) in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and bird (avian) genes and human genes. Scientists call this a "quadruple reassortant" virus.

Swine flu is a respiratory disease caused by a new strain of the influenza virus type A. The strain is known as H1N1 and is the same as the one found in seasonal flu outbreaks, except that it contains genetic material found in birds, humans and pigs. It is now a wholly human virus

How does it spread?

Flu viruses are spread through droplets that fall from your nose and mouth when you cough and sneeze. These particles can be inhaled or transferred to others via hard surfaces, such as door handles, phones, keyboards and remote controls

What are the signs and symptoms of this virus in people?

The symptoms of novel H1N1 flu virus in people include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. A significant number of people who have been infected with this virus also have reported diarrhea and vomiting. Severe illnesses and death has occurred as a result of illness associated with this virus.

In children

  • Fast breathing or trouble breathing
  • Bluish or gray skin color
  • Not drinking enough fluids
  • Severe or persistent vomiting
  • Not waking up or not interacting
  • Being so irritable that the child does not want to be held
  • Flu-like symptoms improve but then return with fever and worse cough

In adults

  • Difficulty breathing or shortness of breath
  • Pain or pressure in the chest or abdomen
  • Sudden dizziness
  • Confusion
  • Severe or persistent vomiting
  • Flu-like symptoms improve but then return with fever and worse cough


Pregnant women
People aged 65 and over
And people with:
n Chronic lung disease
n Chronic kidney disease
n Chronic heart disease
n Neurological diseases (including motor neuron disease, multiple sclerosis and Parkinson's)
n Lowered immune systems
n Diabetes
n A history of being treated for asthma in the past three years


What kills influenza virus?

Influenza virus is destroyed by heat (167-212°F [75-100°C]). In addition, several chemical germicides, including chlorine, hydrogen peroxide, detergents (soap), iodophors (iodine-based antiseptics), and alcohols are effective against human influenza viruses if used in proper concentration for a sufficient length of time. For example, wipes or gels with alcohol in them can be used to clean hands. The gels should be rubbed into hands until they are dry.

Treatment option


Most people will respond well to plenty of rest and paracetamol-based remedies. These should help reduce body temperature and alleviate symptoms


The WHO has recommended only Tamiflu as the drug for treatment. Tamiflu is being dispensed to anyone with symptoms suggestive of swine flu. It is not a cure, but may shorten the duration of illness, reduce the risk of complications such as pneumonia, and make you less contagious if taken within 48 hours of the onset of symptoms. Antivirals are new medicines that don't kill viruses, but keep them from multiplying. Flu viruses are known to die within a week


These have no effect on the virus that is responsible for swine flu but may be prescribed if you develop a secondary bacterial infection, like severe tonsillitis or a chest infection


Globally, two vaccines are in the pipeline and are in the final stages of testing. They should be ready toward the end of 2009, but bulk orders have already been placed by the United States and Europe. Union health minister Ghulam Nabi Azad has promised an indigenous vaccine by January 2010
