BACKGROUND The objective of this study was to investigate risk factors associated with persistent or recurrent upper extremity and neck pain among engineering graduate students. METHODS A random sample of 206 Electrical Engineering and Computer Science (EECS) graduate students at a large public university completed an online questionnaire. RESULTS(More)
Detailed knowledge of the subsurface is a prerequisite for the planning of effective site remediation. Conventional investigation of contaminated sites is based mainly on observations from wells. However, practical limitations on the number of wells mean that characterization of the subsurface based on borehole data alone leads to uncertainties in(More)
The desire to obtain a better understanding of ecosystems and process dynamics in nature accentuates the need for observing these processes in higher temporal and spatial resolutions. Linked to this, the measurement of changes in the external structure and phytomorphology of plants is of particular interest. In the fields of environmental research and(More)
For mapping, quantifying and monitoring regional and global forest health, satellite remote sensing provides fundamental data for the observation of spatial and temporal forest patterns and processes. While new remote-sensing technologies are able to detect forest data in high quality and large quantity, operational applications are still limited by(More)
Polyisobutylene (PIB) is a synthetic elastomer that is a component of sealants, adhesives, and chewing gum base. We report a case of bilateral PIB urolithiasis in a patient with an ileal conduit urinary diversion due to neurogenic bladder from spinal cord injury. Infrared spectroscopy confirmed the composition of bilateral stones and adhesive from the(More)
We conducted a randomized experiment at the time of the 2004 flu vaccine shortage, providing information about the sharply reduced number of clinics and their schedule, and an appeal on cooperative restraint to a campus population. This strategy was intended to reduce demand for vaccination among non-priority individuals and to free available supplies for(More)
