Cooking in microwave oven

                    Microwave Oven works on the principle of passing invisible energy rays called Microwaves through food items. Microwaves are part of the spectrum of electromagnetic waves which includes light waves and X rays. Microwaves, with a wave length between 1 mm and 30 cm are harmful to humans if exposed to it as it generates radiation.

                                    Microwaves can make liquid particles vibrate through which frictional energy in the form of heat is produced. In a microwave oven, microwaves are passed through food. These rays make the water molecules vibrate, producing heat energy. This energy is transferred to the food particles around it. Thus using this energy, food is cooked faster.

       

                                 In the oven, the waves are produced by a 2-electron valve called magnetron, which are scattered around the oven by a metallic fan.

Natural neutralizer for Endosulphan

A study conducted by some Mexican scientists, found that ‘Siva Tulasi’ (oscimum Basilica) have power to neutralize the effects of Endosulphan on soil. It was reported on the‘Journal of hazardous materials’. It was observed that this tulasi has reduced the level of endosulphan in the soil remarkably over the 30 days for which it was observed. It was already found earlier that some plants and bacterias can neutralize the poison content of the soil. But this is a new discovery which could be useful for the victims of endosulphan.

Wayanadan western Ghats rich in bird life

                                   The Malabar ornithological Survey 2010-11, the first ever comprehensive study on fauna in north Kerala, has proved that the Wayanad part of the Western Ghats is acritical habitat for endemic as well as endangered birds. The team sighted 200 species of birds including 14 of the 16 endemic species & 2 critically endangered species, during th 2 month survey in Wayanad district. The findings include the Black-&-orange Flycatcher, Rofous-bellied Shortwing, Nilgiri Flicatchers, Wayanad laughing thrush,etc

Invisible Battle tank

                         Britain has invented a new type of cloaking device that helps to keeps their battle Tanks invisible. It is now used on a light weight vehicle weighing 30 tonnes powered by Hybrid electric drive. It has the same effectiveness and stability of the current main battle Tank-The challenger 2 weighing 62.5 tonnes, and runs a1200hp V12 diesel engine.                                                                        

                     

                          This tank deploys a form of electronic ink to render this vehicle invisible. Electronic sensors attached to the tank’s hull will project images of the surrounding environment back onto the outside of the vehicle enabling it to merge into the landscape and evade attack

Endosulphan

Endosulphan; The curse of Kerala

      Endosulphan has become a serious issue as it is responsible for many deformities and even death in the area were it is sprayed. In 2001, the Achutan committee found that spraying endosulphan is harmful. A study by Habibullah N Sayed of the national institute of occupational health, in the same year, concluded that genetic and reproductive disorders resulted by the use of endosulphan. From mental retardation, deformity to death,  this pesticide has affected thousands in Kasargod district. The endosulphan virudha samara samithi put forward 7 demands that they say are non negotiable

• Ban the pesticide throughout the country & proclaim Kasargod a pesticide-free district.
• Prosecute PCK which is responsible for Endosulphan spraying.
• At least Rs10 lakh to each of the families of the victims. Also minimum monthly pension of Rs5000.
• Distribute the PCK-owned land to the families of the victims.
• Provide adequate rehabitation package for the victims. Build homes for homeless.
• Construct hospitals & sanatoriums in the 11 panchayaths.
• Provide govt jobs to at least one eligible member of the families of the victims
