OHM’S LAW INTRODUCTION Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points‚ and inversely proportional to the resistance between them provided the temperature remains constant. The mathematical equation that describes this relationship is: where V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and

------------------------------------------------- Case Report Female‚ Age 66 years‚ Cervical Dystonia / Torticollis This 66-year-old female was involved in an auto accident 15 years prior in which she was side-swiped at approximately 40kph. Two years after the accident‚ she started to notice slight involuntary movements in her neck. Her symptoms gradually worsened and she was diagnosed with cervical dystonia / spasmodic torticollis. She described that her neck would involuntarily pull in

The tester should be placed on the tooth surface adjacent to a pulp horn (highest density of nerve fibres). According to Lin and co-workers (2007)‚ the optimum site of tester placement on molars is the mesiobuccal cusp tip. An ionic shift in dentinal tubule fluid causes local depolarisation and action potential generation from intact Aδ nerves‚ giving a positive result where the patient feels warmth or a tingling sensation. Reproducibility may be compromised due to

intuitive feel for discretization before going on to write code. Two applications are described. The first is a twodimensional conduction problem that is introduced to show how Solver can be used to solve systems of finite difference equations. The second demonstrates the solution of the incompressible NavierStokes equations using the staggered grid formulation. The conduction problem is one that is easily incorporated into an undergraduate heat transfer class‚ while the flow problem is appropriate

ALL ABOUT ALS MECHANISMS‚ SYMPTOMS‚ DIAGNOSIS AND TREATMENTS! Dawn Prince 11/7/14 7th hour Introduction: So today I’m going to talk about ALS. Mainly about symptoms and what causes Als and why it’s called Lou Gherigs disease. I hope you will like this essay. Als is a very serious disease ths disease kills thousands of people every year. This disease is rare but very deadly. So pleaser take it very seriously. Als affects many people every single day. It takes many lives
