happens in liquids. The liquids that can be electrolyzed are called electrolytes. When said electrolyzed‚ means that the compounds in solutions are broken down when they conduct electricity. Its necessary the use of electrodes since it conducts the electricity to the solution. The electrodes are needed to be an anode‚ which receives the negative ions‚ and the cathode‚ which receives the positive ions. II.

The electrical activity of the heart: the electrocardiogram Electrical activity is a basic characteristic of the heart and is the stimulus for cardiac contraction. Disturbances of electrical function are common in heart disease. Their registration as an electrocardiogram (ECG) plays an essential role in the diagnosis and management of heart disorders. THE GENESIS OF THE ELECTROCARDIOGRAM Pathways of conduction and the electrocardiogram The sinus node is situated in the right atrium

For example‚ a patient with heart disease is usually required to wear a large‚ inconvenient monitor for a month or more in order to capture abnormal but rare cardiac events. Applied just like a temporary tattoo‚ the device sticks to the patient’s skin. The device can bend‚ wrinkle‚ and stretch without being damaged. The best electrodes on the

Transistor A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material‚ with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power‚ the transistor provides amplification of a signal. Today

C2.1.1 Structure and bonding a) Compounds are substances in which atoms of two or more elements are chemically combined. b) Chemical bonding involves either transferring or sharing electrons in the highest occupied energy levels (shells) of atoms in order to achieve the electronic structure of a noble gas. c) When atoms form chemical bonds by transferring electrons‚ they form ions. Atoms that lose electrons become positively charged ions. Atoms that gain electrons become negatively charged

Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known
