Zoroastrianism, Cosmology, and Chaos: A Detailed Analysis of the Musical Composition, Druj Aeterni

Druj Aeterni is a large chamber ensemble piece for flute, clarinet, French horn, two trumpets, piano, two percussionists, string quintet, and electric bass. My composition integrates three intellectual pursuits and interests, ancient mythology, cosmology, and mathematics. The title of the piece uses Latin and the language of the Avesta, the holy book of Zoroastrianism, and comments upon a philosophical perspective based in string theory. I abstract the cosmological implications of string theory, apply them to the terminology and theology of Zoroastrianism, and then structure the composition in consideration of a possible reconciliation. The analysis that follows incorporates analytical techniques similar to David Cope’s style of Vectoral Analysis

Secondary amenorrhea

This issue of eMedRef provides information to clinicians on the pathophysiology, diagnosis, and therapeutics of secondary amenorrhea

What test is the best for diagnosing infectious mononucleosis?

Tests for antibodies to Epstein-Barr viral capsid antigen (EBVCA) or Epstein-Barr nuclear antigen (EBNA) are the most sensitive, are highly specific, and are also the most expensive for diagnosing infectious mononucleosis (strength of recommendation [SOR]: C, based on validating cohort study). Heterophile antibody tests have similar specificity and are cheaper, but are less sensitive in children or in adults during the early days of the illness (SOR: C, based on validating cohort study)

The high energy scattering of photons and alpha particles by hydrogen atoms

The major part of the thesis I concerned with the methods used to obtain approximate values of cross sections for rearrangement processes in which protons and alpha particles are scattered from hydrogen atoms. Some of the relevant experiments are briefly described in Chapter 1 and time dependant scattering theory used n Chapter 2 to derive an exact depression for the cross section. Born expansions of the transition amplitude are introduced and in Chapter 3 some OBK and Born approximation calculations are discussed. Distorted wave, impact parameter and second order methods are considered in Chapters 4, 5 and 6, numerical results being given where possible. A new integral equation for the transition amplitude. The impulse approximation forms the subject of Chapters 7 and 8. A new derivation, due to Coleman, is given and calculations for the process. H(^+) + H (1s) →H(2p, 3s or 3p) + H(^+), H(^+) + H (2s) → H (2p) + H(^+), and He(^++) + H(1s) →He(^+) (2p or 3s) +H(^+), are described. The results are compared with those obtained by other workers. They are used to calculate the polarization of Lyman-alpha radiation emitted by 2p hydrogen atoms formed by capture and to investigate the n(^-3) rule by which estimates of total cross sections are often obtained. The asymptotic form of the electron capture cross section as the velocity of the incident particle tends to infinity is discussed in Chapter 9. A brief survey is given of the forms predicted by the various theories described in previous chapters. The high energy form of the modified first Born approximation derived in Chapter 4 is then considered. It is found that, with the approximations made, it is the same as that of Drisko's Second Born approximation
