The influence of stages of development, soil types, dates of seeding, cultivars, and boron nutrition on glucosinolate composition and variation in rutabaga (Brassica napobrassica Mill.) and turnip (B, rapa L.) cultivars was studied by quantifying the glucosinolate hydrolysis products in these species. While in seeds of both species contents of goitrin and volatile isothiocyanates were inversely correlated, there was little variation in thiocyanate ion and total glucosinolate contents. Major synthesis or accumulation of different glucosinolates occurred at different times during the growing season in the sequence after seeding: indolyl glucosinolates yielding thiocyanate ion at the 2-week stage; glucosinolates yielding volatile isothiocyanate hydrolysis products at the 4-week stage; and progoitrin yielding goitrin at the 6- or 8-week stage. These glucosinolates were generally higher in roots of both species grown on organic soil than on loam soil. During ontogeny of both species, the content of volatile isothiocyanates generally were positively correlated with top/root ratio, while growth rate was positively correlated with thiocyanate ion content. While the contents of goitrin and volatile isothiocyanate tended to be higher in early-seeded (May 27) crops, the thiocyanate ion contents tended to be higher in late-seeded (June 21) crops. The occurrence of boron deficiency symptoms in roots of hydroponically-grown Snow Ball turnip (0.1 ppm boron treatment) was associated with an accumulation of high quantities of glucosinolates and reducing sugars.

The past half-decade has seen progress in methodology and reusable components available to designers of music authoring tools. This thesis examines currently prevalent architectures for music making software and applies currently available technical means to update design methodology and architectural patterns for the next-generation of tools. It aims to map the various categories of advances and the manner in which they relate to each other, to the problem of building these tools. The focus is on conceptualization. The thesis aims to understand, from historical perspectives, as well as from perspectives provided by other domains, the fundamental problems encountered in the process of designing authoring tools. / Issues examined include building rich visual and interactive interfaces for authoring, the use of multiple notations and formalisms to describe multiple aspects of musical structure, end-user extensibility and end-user script ability. The results of design experiments implementing core ideas are documented, and the manner in which the ideas from these prototypes may be applied to the construction of real-world tools is discussed. As far as possible, the thesis investigates existing tools, frameworks, design ideas, and architectural possibilities that scale. In conclusion, the manner in which the investigation relates to the future of authoring tools, and to problems faced by contemporary artists and tool-makers is discussed.

This study will prove the fact that computers provide unprecedented opportunities to create music. Several distinct levels of computer participation can exist in the creative process. The lowest level, involving record-keeping functions, results in programs that serve as compositional aids. The intermediate level incorporates stochastic (literally "random") processes on a limited basis, and represents the midpoint between computer-assisted and computercomposed works. The highest level focuses on the design of algorithms that result in compositions determined in most of their details by stochastic processes and computer decision making. Although there is no clear dividing line between levels of computer/composer interaction, it is possible to characterize the degree to which the computer has provided outcomes for a given work, from low-level random generation of pitches to high-level Markovian chain distributions. / Department of Computer Science

The construction of critically literate students must be paramount among goals in the freshman composition classroom. The approach for constructing critical readers positioned in this thesis employs conceptualizing both the complexity of a text and the importance of comprehending the context within which a text is both read and written. It utilizes the rhetorical feature of irony.
