Advances In Biomolecule Analysis: Ftms Of Macromolecules, Curtiss D. Hanson, Ira M. Simet, Suzanne R. Smith
Journal of the Iowa Academy of Science: JIAS
The development of Fourier transform ion cyclotron resonance (FT-ICR) as an analytical technique has opened new avenues to the analysis of high molecular weight biomolecules. Because mass analysis is based on a detection of a frequency, it is possible to obtain high resolution mass measurements without sacrificing sensitivity. The unique ability to analyze high mass ions is based in the design of a passive ExB ion trap. Although in the past, field inhomogeneities have limited this technique, recent developments in both trap designs and excitation techniques have resulted in major improvements in both sensitivity and resolution.

Prof Geoff Masters AO
It is important that students of physics develop both quantitative and qualitative understanding of physical concepts and principles. Although accuracy and reliability in solving quantitative problems is necessary, a qualitative understanding is required in applying concepts and principles to new problems and in real-life situations. If students are not able to understand what underlies quantitative problem-solving procedures nor interpret the solution in physical terms, it is questionable whether they have developed an adequate understanding of physics. The research reported here is part of a larger phenomenographic study that is concerned with the assessment of physics students' understanding of some basic …

Natural History In Iowa: The Early Phases, David C. Glenn-Lewin, Thomas R. Rosburg
Journal of the Iowa Academy of Science: JIAS
Natural history in Iowa prior to the 20th Century can be conveniently arranged into 4 phases: Native American, before the Louisiana Purchase, between the Louisiana Purchase and about 1850, and after 1850. Native American natural history was extensive and had a distinctly spiritual character. Natural history was a component of European exploration up to the time of the Louisiana Purchase, but was not treated as a separate endeavor; the evidence from this period comes from the journals and diaries of early exploreres, fur traders and the like. Between the Louisiana Purchase and about 1850, natural history changed from its status …
