The purpose of this study was to characterize the nonvolatile,
water soluble, bis(hydroxyalkyl)N-nitrosamines produced from the
reaction of spermidine and nitrite.
The biologically occurring polyamine spermidine was reacted
with nitrite in the presence of acid. The reaction products were
isolated and converted to trimethylsilyl (TMS) derivatives. The
derivatized products were...
Purpose of the Study: The major concern of the study was to determine those factors in clothing and textiles, exclusive of clothing construction, which current home economics teachers felt were necessary for novice teachers to be proficient in. The objectives of the study were: 1. To evaluate, revise, and expand...
This investigation attempts to demonstrate that the development
of the early 20th century biological enterprise involved a striving for a
unifying theoretical perspective. A skeletal substantiation of this is
given by an overview of early 20th century biology in which some
biologists began recognizing a multiplicity of different orders of...
This study Is a rhetorical analysis of ten documents of Joseph
Smith, Jr's. early revelations spanning the period of 1829 to 1831
to determine the extent to which he used demagogic rhetoric in pursuit
of his goals. A definition of demagoguery is provided and is
applied in an analysis of...
Heparin was modified and immobilized to surface-activated silica surfaces using two different reaction schemes. End-aminated heparin was reacted with 2-iminothiolane to produce free thiol groups at the terminal ends of the heparin chains. The end-thiolated heparin was immobilized by reaction with a pyridyl disulfide activated poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock...
