  • The microstrip ring resonator was first proposed by P. Troughton in 1969 for the measurements of the phase velocity and dispersive characteristics of a microstrip line. In the first 10 years most applications were concentrated on the measurements of characteristics of discontinuities of microstrip lines. Sophisticated field analyses were developed to give accurate modeling and prediction of a ring resonator. In the 1980s, applications using ring circuits as antennas, and frequency-selective surfaces emerged...

  • Magnetic resonance spectroscopy (MRS), unlike conventional magnetic resonance imaging (MRI), provides information on the brain’s chemical environment (rather than neuroanatomical structure) and the data are most commonly presented as line spectra. This capacity for determining brain metabolite concentrations provides the basis for clinical investigation of, and differentiation between, neurological and neurosurgical conditions.

  • Chapter 22 - What does the benzene ring do to its substituents? After attending lectures, reading the text and working assigned problems related to this chapter, students will have acquired the following knowledge and abilities: Given the IUPAC name of a phenol derivative, be able to draw its structure; know how resonance influences the stability of benzylic cations, anions, and radicals as compared to similar non-benzylic species; be able to apply a benzyl ether as a protecting group in multi-step synthesis; given a series of phenols, be able to rank their relative acidity.
