Chapter 4‚ page 1 4 Nuclear Magnetic Resonance Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then‚ the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances‚ the transitions between two branches of a single energy level

CBBE Pyramid Powerful brands create meaningful images in the minds of customers (Keller‚ 1993). A strong brand image and reputation enhances differentiation and has a positive influence on buying behaviour (Gordon et al.‚ 1993; McEnally and de Chernatony‚ 1999). A brand is a bundle of functional‚ economic and psychological benefits for the end-user (Ambler‚ 1995). Brand equity‚ as defined by Keller (1993)‚ occurs when a brand is known and has some strong‚ favourable and unique associations in a

There will be a net force from the pressure to push the piston back out. Since gas has mass it can support oscillations and waves. 2.2 Traveling Sound Waves

History and Science Behind MRI: Open or Closed Case? Magnetic Resonance Imaging (MRI) has been called one of the most comprehensive and efficacious diagnostic imaging modalities in medical history. It became a viable clinical technique in 1982 and during its relatively short lifetime has become the primary imaging modality for investigations of the brain‚ spinal cord‚ spine‚ cancellous bone‚ and joints. It is widely used for the identification and staging of tumors‚ investigations of large

Egyptian and Mayan Pyramids Can you imagine building something almost as big as eight football fields? Skilled laborers who built the Pyramids of Giza and the Mayan pyramids built them almost or that big! The Pyramids of Giza and the Mayan pyramids are fascinating insights upon history. These pyramids are attached to great tradition as well as an historic past. They had similar and different features. This is what made them so unique and special. As you will see‚ these breathe taking pyramids shine on their

Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan‚ you lie inside the tube. Almost any part of the body can be examined using an MRI‚ including the brain and spinal cord‚ bones and joints‚ heart and blood vessels‚ internal organs‚ and breasts. MRI scans are safe and painless. Almost everyone

The Romantic Movement emphasizes the value of individual experiences‚ the contemplation of the emotional resonance of those experiences‚ and the exhibition of those emotions. Freder and Maria‚ the main characters in the movie Metropolis‚ demonstrate these traits by freely communicating their emotions in an unnatural and technologically advanced society Freder is a Romantic Hero of Sensibility‚ a hero distinguished by a capacity for tender emotion instead of intelligence or great deeds. Freder is

MAGNETIC RESONANCE IMAGING Magnetic resonance imaging (MRI) has developed into one of the most versatile techniques in clinical imaging and biomedical research by providing non-invasively high resolution‚ three-dimensional anatomical and contrast-enhanced images of living tissue. The two most common groups of contrast-enhancing agents are gadolinium-based complexes and magnetic nanoparticles. Both types of contrast agents shorten locally the relaxation time of bulk water protons via rapid exchange

UVA-OB-0626 RESONANCE‚ LEADERSHIP‚ AND THE PURPOSE OF LIFE I’ve always been interested in the mountains. The first time I went to Switzerland‚ I saw the mountains‚ and I said‚ “This is where I’ve got to be.” I dropped everything and found a mountain-climbing school and spent a couple of weeks in Switzerland and learned some basics of climbing‚ how to cut ice steps in glaciers and basic mountaineering. I really liked that. Clearly‚ in technical climbing you get in situations where‚ if you
