Spinal At T 10 ( 10 th Thoracic )

Background : The historical evidence of the use of “general spinal anesthesia” introduced by Thomas Jonnesco in 1909 for the surgeries of the skull, head, neck and thorax puncturing the subarachnoid space (SAS) between 1 and 2 thoracic vertebra producing perfect and deep analgesia for the above mentioned area influenced to puncture SAS at 10 thoracic vertebra (T10) in place of puncturing SAS be...

A Position Sensitive Detector for 1 - 10 MeV Gamma RaysJoel

A position sensitive detector for 9 MeV gamma rays has been developed as part of a contraband detection system for airports. The system images contraband, such as explosives or drugs, in a geometry similar to medical x-ray computed tomography. A point source of gamma rays shines through an unknown object. Transmission projections of the areal density of detected gamma rays are reconstructed int...

Chapter 10 Representations of Lie Groups 10 . 1 Fundamental Weights

Let us label the simple roots ~ α, i = 1, . . . , m. They and their conjugates generate (not linearly) any element of the Lie algebra. Thus any representation can be determined by how it behaves under these roots. The weights have an ordering, so any finite dimensional representation has a greatest weight ~μmax. The weight ~μ of a basis element is ~μmax if and only if ~μ+~ α is not a weight for...
