visually impaired has a problem with the retina, it stops converting light energy to electrochemical signals. As a signal is not received by the brain; a complete image is not formed and results to blindness. The chip has a large number of electrodes, because more electrodes results in a higher pixel count and clear vision for the patient. The bionic eye used today uses glasses with a camera to produce radio waves to the chip that produces electrical impulses which stimulates cells to the optic…

Electrodes were also placed on the girls at the midline of her scalp. An EEG, to record to duration of the seizure as well as the amplitude of electrical spikes within the brain. The seizures would last 20 to 30 seconds, with jerking movements in her right…

The ECG/EKG When most people think of heart tests, they think of the ECG. ECG stands for electrocardiogram. It's also called an EKG, from the German elektrokardiogram. Although it may look like an ECG is recording heartbeats, it's not. In fact, it records the electrical activity (the electrical triggers, if you will) that presage the actual heartbeat. The mechanical beats follow the electrical triggers by about a tenth of a second -- unless, of course, there's a problem. Or to state it in…

For instance, the tip of the lead contains four electrodes. Each of the electrodes stimulate an area of the tissue. Also, the other end of the lead is connected to a neurostimulator by an extension wire. Also, the neurostimulator produces the stimulatory pulses, and these are transmitted to the leas by the extension…

1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…

cyclotron allows for a much longer acceleration path than a straight line accelerator. The cyclotron body consists of electrodes (they are called dees because they look like the letter D) in the vacuum chamber. This chamber is flat and sits in a narrow gap between poles of a large magnet creating a perpendicular magnetic field. A high frequency voltage is applied across the electrodes as a surge of charged particles is fed into the centre of the chamber accelerating the charged particles…

High frequency (14 Hz), Low energy intensity five mA and pulse width 330 micro secs) via external programming system. Enterra system consists of two muscular electrode wires connected to pulse generator device and external programming system. The implant of the device and electrode requires laparoscopic surgery to embed a pair of electrodes into muscular propria of stomach separate 1 cm at 10 cm proximal to the pylorus. The pulse generator will be placed into a subcutaneous pocket beneath the…

Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…

The Lincoln Electric Company is considered the largest manufacturer of welding machines and electrodes. Many college management texts refer to the Lincoln plan as a model for achieving worker productivity because it has been well known for many years and has been a successful company according to the usual measures of success. In 1895, John C. Lincoln began to manufacture his improved motor and opened his new business unincorporated with a $200 he had earned redesigning a motor for Herbert Henry…

Patients with DRE have an increased mortality rate. “The standardized mortality ratio for patients with recurrent seizures is 4.69”. 2 Many studies have taken place to examine models of temporal lobe epilepsy. Studies with multiple implanted EEG electrodes at various brain regions, observed that response to epileptogenic drug /high stimulation was higher and faster at hippocampus than at other regions. Also tissue damage in the hippocampus is more visible. Hence we focus our study in the…
