It contains the agarose gel that will be loaded with genetic material‚ as well as a buffer solution. It is connected to a DC power supply via electrodes. This picture was taken at Paw Print Genetics laboratory in Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field

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

the patient through the monitor. I completed skin preparation of the patient’s skin before I placed on the ECG electrodes. Skin preparation is done by using a skin abrasion pad and an alcohol wipe. If the male patient had a hairy chest‚ I would ask for the patient’s consent to remove the chest hair before doing the skin preparation (Passanisi‚ 2001). I hook up the leads to the ECG electrodes and started the patient’s monitor to record their ECG for the 24-hour period. Reflection Observation At the

like any normal battery my salt water battery has the three main components‚ the electrolyte (in case you didn’t know its like a liquid that conducts th electric current (I hope I spelt that right))‚ a cathode (the negative electrode) and the an anode (the positive electrode). As you may or may not know a chemical reaction must occur so that that chemical energy can be converted into electrical energy which is then used for whatever. In my salt water battery the electric current passes through 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

VINEGAR (ACETIC ACID) AS ALTERNATIVE BATTERY Battery or more precisely‚ a cell – is a device in which the reaction between two substances can be made to occur in such a way that some of the chemical energy is converted to useful electricity. Since its invention‚ the battery has become the most common power source for many household and industrial applications. There are many ways to construct a battery‚ as well as ways to control its generated output. This Home-made Vinegar Battery is a battery
