Lazaro Castillo 04/16/2012 Infectious Diseases One infectious disease I will be discussing is called Diphtheria. Diphtheria is a highly contagious bacterial infection‚ which mainly affects the nose‚ throat and occasionally the skin‚ but in more serious cases‚ it can attack the heart and nerves. Diphtheria is caused by a bacterium known as C. diphtheiae. The bacteria produce a toxin (poison) that is carried in the bloodstream and causes tissue damage in the area of infection‚ usually the nose

Introduction to AC Machines Dr. Suad Ibrahim Shahl 3 AC winding design The windings used in rotating electrical machines can be classified as Concentrated Windings • All the winding turns are wound together in series to form one multi-turn coil • All the turns have the same magnetic axis • Examples of concentrated winding are – field windings for salient-pole synchronous machines – D.C. machines – Primary and secondary windings of a transformer Distributed Windings • All the

Move the compass slowly along a semicircular path above the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. The white lead of the needle faces the South part of the magnet in a perpendicular way. When the needle is facing the center of the magnet‚ the lead turns to a 90 degree angle

Batch: 10 Roll: Sh-099 Introduction The basic theory on a ballistic galvanometer starts with torque associated with a current carrying loop. A brief review of ordinary moving coil galvanometer is presented followed by the effects of transient currents. This paves the way for a detailed analysis of ballistic galvanometer. Torque on a Current Loop It is well known that a current loop behaves like a magnetic dipole. The magnitude

Dengue Fever Kimberly A. Bitanga Microbiology Professor J. Gray Dengue Fever Abstract Dengue fever is a debilitating tropical disease caused by one of five types of the dengue virus.(1) It is transmitted by mosquitos throughout the tropics and subtropics of not only Southeast Asia‚ but has now spread to Central and South America‚ and countries in the Pacific Ocean and America as well. Usually‚ most people who are infected with the virus are asymptomatic‚ with mild symptoms‚ whereas others develop

1. Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the

flux that occurred when the battery was connected and disconnected.[1] Within two months‚ Faraday found several other manifestations of electromagnetic induction. For example‚ he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires‚ and he generated a steady (DC) current by rotating a copper disk near the bar magnet with a sliding electrical lead ("Faraday’s disk").[8] Faraday explained electromagnetic induction using a concept he called lines of force. However‚ scientists

It is basically an electromagnet | Rotor coil(s) | There may be only one‚ in a very simple motor‚ or several coils‚ usually of several turns of insulated wire‚ wound onto the armature. The ends of the coils are connected to bars on the commutator. | The coils provide torque‚ as the current passing through the coils interacts with
