1. Introduction 22 Diabetes mellitus is the 7th leading cause of death in US. Diabetes is broadly classified into two 23 types: type I and type II. Type I diabetes is a result of insufficient insulin production by pancreas‚ 24 whereas type II diabetes is due to the body’s inability to use the insulin that is produced‚ hence the 25 name insulin resistance is used to refer to type II diabetes. Currently‚ individuals with diabetes are 26 able to monitor their blood glucose levels using a glucometer

ABSTRACT The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials

It simply measures and averages the difference between the electrical potential of electrode sites for each lead and graph them over time‚ creating the started ECG complex‚ called PQRST (Nurse’s Quick Check: 2006). It is noninvasive‚ virtually risk free‚ and relatively inexpensive. It uses 10 electrodes to measure electrical potential from 12 different leads. Variations of

A Description of Cochlear Implants A Cochlear Implant is a specialized hearing device that consists of both a surgically-implanted and external component used to simulate natural hearing. This device is used to treat people with severe and profound hearing loss. The implanted component is placed under the skin‚ behind the patient’s ear‚ and connected to the auditory nerve of the brain. The Cochlear Implants are designed to receive sounds and convert them into electrical signals that bypass

The bipolar limb leads will be placed on the torso for exercise testing. Place the right arm electrode just below the right clavicle‚ the left arm electrode just below the left clavicle‚ the right leg electrode (the ground lead) on the right side of the navel‚ and the left leg electrode on the left side

The zinc half-cell is used as the reference standard and assigned an E of 0 volts‚ and all reduction potentials are measured with respect to the zinc electrode. In Part 2‚ the Nernst equations applied to the voltage measurement of a cell with nonstandard copper ion concentration. A solution of 0.0010 M Cu2 + is prepared‚ and the voltage of the cell: Zn(s)| Zn2+(1.0 M) || Cu2+ (0.0010 M) | Cu(s) is measured
