Non Destructive Test (NDT) X-Ray Advantages of X-Ray X-rays are invisible electromagnetic energy, which is used as a way to get or make images of internal tissues, bones and organs of our body. It is by this process that an expert determines bones of a patient are intact or broken after an accident. Likewise, you can find internal injuries to organs. In addition, X-rays are used to find out whether or not a person has a cancerous tumour. With the increasing technological advances, the

These few large companies operating in an oligopolistic market affects each other when they decide to change their price and output. In the Oil Field Division of Lufkin Industries, producing their output like the Air Balanced Pumping units are very expensive that any change in price or output should be well planned and researched to avoid increase cost especially labor cost.

(C.J.G. Onderwater) Overview The sensitivity with which an EDM can be sought for is to a good approximation given by sd ∝ 1 PE N T tot A Here P is the (transverse) polarization of the beam at the time of injection, E the effective electric field, N the number of particles stored per fill, Ttot the total running time of the experiment, τ a characteristic time scale and A the analyzing power of the polarimeter. The characteristic timescale depends on the lifetime of the beam in the storage

would be the poem In Flanders Field by Dr. John McCrae. I have known this poem for most of my life growing up. We would always learn about it in school around Remembrance Day. As Canadians, this poem is very important because it was written in the First World War by a Canadian lieutenant who was inspired to write it after the death of his friend. It reminds us about how we are free and what people did so that we could live in a free country. In Canada, In Flanders Field is one of the nation’s best-known

Introduction 2) Synchronous machine structures 3) Rotating magnetic field 4) Equivalent circuit model 5) Performance as a generator 6) Performance as a motor Introduction A synchronous machine is an ac rotating machine whose speed under steady state condition is proportional to the frequency of the current in its armature. The magnetic field created by the armature currents rotates at the same speed as that created by the field current on the rotor, which is rotating at the synchronous speed, and
