Leon Breeden Personal Cassettes Tapes, circa 1950-2007
No full textRecording of Leon Breeden recording an audio correspondence for Allen Scott. In this recording, Breeden speaks about his personal thoughts on the jazz field and jazz education. These thoughts were used in Allen Scott's article in The NAJE Educator, Feb/March 1978 Vol. X, No. 3 issue on the past ten years of jazz education

Leon Battista Alberti: <i>On Painting</i>
No full textLeon Battista Alberti was one of the most important humanist scholars of the Italian Renaissance. Active in mid-fifteenth-century Florence, he was an architect, theorist, and author of texts on perspective and painting. Leon Battista Alberti: On Painting is a cardinal work that revolutionized Western art. In this volume Rocco Sinisgalli presents a new English translation and critical examination of Alberti's seminal text. Dr Sinisgalli reverses the received understanding of the relationship between the Italian and Latin versions of Alberti's treatise by demonstrating that Alberti wrote it first in Italian and then translated it into a polished Latin over the course of several decades. This volume is richly illustrated to help demonstrate how Alberti understood optics and art.</jats:p

Physics of the central engine and nuclear regions in radio-loud active galactic nuclei
No full textDespite the overwhelming observational evidence supporting the unified scheme of Ac-
tive Galactic Nuclei (AGN), there is no compelling reason for AGN constituents to be the
same in every AGN. The observed properties of AGN at different wavelengths (from radio
to γ-rays) can depend on the location of the respective emitting regions and density and
composition of the emitting material. In this dissertation we study the couplings between
the emission from the central engine of radio-loud AGN. The main results of this disserta-
tion come as follows: (i) The double-peaked emission lines originate most likely in the outer
parts of the accretion disk, have been used as tools for studying the structure and dynamics
of accretion disk. The distribution of Eddington ratios for a large sample of AGN in the
sample has a two component structure peaked at low and high Eddington ratios. The break
in the distribution at Lbol/LEdd ∼ 10−3 coincides with the typical Eddington ratio for AGN
with broad and double-peaked emission lines. We propose an evolutive scenario where the
double-peaked phenomenon is a short-term state transiting between high and low efficiency
accreting systems, when the difference between different accretion states manifest itself in
a spectral (AGN type) difference between efficient and inefficiently accreting objects. (ii)
There is a significant difference in Eddington ratio between radio-quiet and radio-loud
AGN with double-peaked Balmer emission lines. In this dissertation, we show that double-
peaked emission can be generated as well in an accelerating outflow material located in the
radio jet. (iii) We combine for the first time high resolution VLBI monitoring of compact
jets with optical continuum observations and study in detail radio-optical correlations in
AGN
