The energy of wind converted into useful form (usually electric current) is called wind energy. Wind energy is a Renewable energy source.Once used can be replaced. Example: Windmill It is a machine which converts the energy of wind to rotational energy with the help of large blades attached to it.he energy of wind converted into useful form (usually electric current) is called wind energy. Wind energy is a Renewable energy source.
Defining Seizures. A seizure can be defined as abnormal, uncontrolled electrical activity in brain cells. Nerve cells transmit signals to and from the brain in two ways by (1) altering the concentrations of salts (sodium, potassium, calcium) within the cell and (2) releasing chemicals called neurotransmitters (gamma aminobutyric acid).
Seizures and Neurological Issues. Seizures are periods of sustained hyperactivity in the brain. During a seizure, the nerve cells leave their normal activities, and fire in massive, synchronized bursts. After a few seconds or minutes, the brain regains control and the person returns to normal.
