α [Greek small letter alpha]-Nitrosulfones: Synthetic and mechanistic studies
Three-α-substituted nitroethylene derivatives were prepared in situ from phenylsulfonylnitromethane, α-nitroacetophenone, and ethyl nitroacetate and allowed to react with a series of dienes to yield the corresponding Diels-Alder cycloadducts. The same nitroethylene derivatives were also prepared from the corresponding β-sulfoxides via elimination. The β-sulfoxides were prepared from the corresponding β-sulfides which were in turn prepared by trapping the nitroethylene derivatives with thiop
Novel associated PVA/PVP hydrogels for nucleus pulposus replacement
Degenerative disc disease in the lumbar spine is marked by a dehydration of theintervertebral disc and loss of biomechanical function of the spinal unit. Since thecurrent surgical procedures are ineffective in restoring natural biomechanical functionback to the diseased disc, researchers have looked to replace the intervertebral disc.These designs are flawed in that they either donâ t restore natural movement back to thespinal unit, require surgeries that are highly invasive, or they further p
Biomechanical evaluation of the intact, injured and surgically reconstructed ulnar collateral ligame
The ulnar collateral ligament (UCL) of the elbow is a major passive stabilizer againstvalgus moments and is a frequent site of injury for the professional throwing athlete. Due to theimportance of the UCL in elbow stabilization, many clinical and biomechanical studies wereconducted in the past to understand its role; however, no study has evaluated the stabilizingfunction of the UCL when subjected to a pure valgus-varus moment at varying degrees of flexion.In addition, few comparative studies ha
Frequency domain blind multiple-input multiple-output system identification
Since commercial banks play important roles in the financial markets, it is important to evaluate whether banks operate efficiently. Moreover, given increased competition from non-bank financial institutions, commercial banks should operate more efficiently than they did previously. Commercial banks might operate more efficiently if they have superior information. If this is true, bank size should not matter to the operation of the bank. Thus, as long as the bank has superior information, it wil

SIMply Prairie
SIMply Praire is a student research project that has the potential to link classrooms in areas where the prairie once flourished. Students develop research questions with a special focus on the prairie plant population. To answer these questions students conduct a research study collecting data from a prairie plot and comparing their data with data from other native and/or reconstructed prairie plots. Students publish their data and their research study on the SIMply Prairie Website. As the proj
SIMply Prairie: Prairie Advocates
In this multidisciplinary, inquiry-based project students prepare a plan and give a persuasive oral presentation to create a reconstructed prairie based on research. Teachers can use this unit with their students to justify enlarging or keeping an existing prairie. This project can serve as the organizing structure for prairie study where materials from units such as The Prairie – Our Heartland become research materials. It can be used in conjunction with the unit which is taught best in the f
Introduction to New Testament History and Literature
This course provides a historical study of the origins of Christianity by analyzing the literature of the earliest Christian movements in historical context, concentrating on the New Testament. Although theological themes will occupy much of our attention, the course does not attempt a theological appropriation of the New Testament as scripture. Rather, the importance of the New Testament and other early Christian documents as ancient literature and as sources for historical study will be emphas
PTC 624: Professional and Technical Editing
This seminar introduces students to contemporary editing strategies. As information managers within organizations, twenty-first century editors must be able to demonstrate proficiency in a wide range of areas, from working with writers to improve the tone of a manuscript to providing warranted evidence in support of copyediting changes. Topics will allow students to encounter a wide range of experiences, from production-oriented aspects of project management to document-based forms of electronic
Quantum Dots
Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application opportunities in optical sensors, lasers, and advanced electronic devices for memory and logic. This seminar starts with an overview of wavelike and particle like properties and motivates the existence of quantum mech
The Structures of Life
This site takes us into the world of structural biology -- a branch of molecular biology that focuses on the shape of nucleic acids and proteins (the molecules that do most of the work in our bodies). Learn about the structures and roles of proteins, tools used to study protein shapes, how proteins are used in designing new medications (for AIDS and arthritis), and what structural biology reveals about all life processes. Find out about careers in biomedical research.
Living Pura Vida | University of St. Thomas
In early August 2010 Shelley Coughlin, a pre-med student at the University of St. Thomas, joined about 30 college students from across North America on a volunteer trip to Costa Rica and Nicaragua.
The students, with varying areas of study, provided medical, dental, or veterinary care to the under served communities they visited.

Culturally Engaged Instruction (CEI): Putting theory into practice
As an English teacher at a rural all-Black high school in the Mississippi Delta, Renee Moore enjoyed a genuine fellowship with her students, many of whom she worked with outside of school in church and community activities. Lessons in literature and writing went reasonably well (for a beginning teacher), but when she started to teach grammar, her students seemed to 'hit a brick wall.' She had two simultaneous responses to the wall. She immediately started searching for and experimenting with mor
Consulting pupils about teaching and learning
The resource is a summary, appearing on the GTCE website, of a three-year research project, led by Professor Jean Rudduck, as part of the Economic and Research Council, Teaching and Learning Research Programme. The project, a Research for Teachers (formerly Research of the Month) case study, considers the impact of consulting pupils about teaching and learning.
