Name: Nikia Martinez Class: Biology 240L L3-1201 Assignment: Electrocardiography Lab Report Due: April 3rd 2012 Professor: Dr. B. Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

decimal. It appears to be an error in the measurement of the 10^-6 solution because it only differs by 7mv and each solution should increase or decrease by 0.059v or 59mv. It is theorized that this small change in measurement is because the electrode has a hard time detecting the mV of such a small concentration. Taking this into consideration the remainder of the points should be correct. They each increase by approximately 59mV as

select the optimum pacing modes for individual patients. Some combine a pacemaker and defibrillator in a single implantable device. Others have multiple electrodes stimulating different positions within the heart to improve synchronisation of the lower chambers (ventricles) of the heart. How does it work?

UNIT 5 – ELECTROCHEMISTRY Chapter 9 – Electric Cells 9.1 – Oxidation and Reduction * The term reduction came to be associated with producing metals from their compounds. * Ex. Fe2O3(s) + 3CO(g) 2Fe(s) + 3CO2 * Another substance‚ called a reducing agent causes or promotes the reduction of a metal compound to an elemental metal. In this example‚ it is CO. * Corrosion‚ including the rusting of metals‚ is now understood

considerations Strength Safety Feel free to ask questions at any questions at any time. Arc Welding • Welcome to the world of WELDING What is Arc Welding? An electric arc between the and electrode and the work piece generates heat. Sufficient heat is generated to melt the work pieces together. ELECTRODE ARC WORK PIECES Electricity The range of welding current used can be from 5 to 500 amps. The voltage ranges from 20 to 30 volts‚ AC or DC. Both are determined by the material thickness.

typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0.06 volt per pH unit) that is measured and displayed as pH units by the meter. For more information about pH probes‚ see glass electrode.
