Technological Development
The application of scientific knowledge for practical purposes, especially in industry, is called as technology.
HEC to make Wind Turbines
The Heavy Engineering Corporation (HEC), Ranchi, Jharkhand has decided to make turbine for generating electricity from the Wind Energy. For this HEC has decided to take technology from the Sky Wind, a company of Germany.
Value of Birds that Live in Our Surroundings
For one it is the indication of meeting the other, either boy or the girl. This belief prevails in many parts of India including Jharkhand. If by chance, you spot a single myna, it is sure that your day is going to be alone on the whole. It comes true most of the time.
Flax – Farming, A Better Option for Jharkhand
In irrigated conditions 80 kg of Nitrogenous fertilizers, 30 kg of Phosphorus, 20 kg of Potassium and 20 kg of Sulphur fertilizers are recommended in one hectare of land for the linseed cultivation.
What is Ozone layer? How is it depleted and what are the control measures?
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
Interactions between members of a species
Living beings interact among themselves in the same species, with the members of the other species, and with the components of the abiotic environment in an ecosystem.

Technological Models
Recently, it has been found that Photo Voltaic Cells cannot be popularly used for power generation on large scales. However, our scientists have discovered that the alignment of Carbon Nano Tube with the polymer composites substrate would give very high efficiency in Photo Voltaic Conversion.
Importance of forests and Wildlife
Forests and wildlife are integral part of environment. Forests control climate, soil erosion and wildlife. They cause rains.
