Hepatitis C virus transmission during organ transplantation
(W.B. SaundersWiley Periodiocals, Inc., 1993-01)
Background . There is a high prevalence of liver disease among the recipients of organs from donors with antibodies to hepatitis C virus (HCV). We undertook a study to determine the frequency of persistent HCV infection, ...
Observations of the quasi 2‐day wave from the High Resolution Doppler Imager on Uars
(Wiley Periodicals, Inc.McGraw‐Hill, 1993-11)
High-pass filtering to remove electrocardiographic interference from torso EMG recordings
(Elsevier, 1993-01)
SummaryRemoval of electrocardiographic (ECG) contamination of electromyographic (EMG) signals from torso muscles is often attempted by high-pass filtering. This study investigated the effects of the cut-off frequency used ...
Field investigations of the performance of air bag deployments in frontal collisions
(Elsevier, 1993-12)
This paper documents field investigations of "air bag" crashes selected from a large group of air bag crashes in file at the University of Michigan Transportation Research Institute (UMTRI). A full range of crashes are ...
Reactive Cerium(IV) Oxide Powders by the Homogeneous Precipitation Method
(Blackwell Publishing Ltd, 1993-06)
Helpless behavior
(Elsevier, 1993-03)
In the present research, we investigated helpless behavior and the responses it elicits from others. Study One used the act-frequency approach to develop a self-report measure of prototypically helpless behaviors. In a ...
Monte Carlo studies on the well‐width dependence of carrier capture time in graded‐index separate confinement heterostructure quantum well laser structures
(The American Institute of Physics, 1993-10-04)
The total carrier capture time and the quantum well width are both important parameters affecting the graded‐index separate confinement heterostructure (GRINSCH) quantum well laser modulation speed limit. However, discrepancies ...
A Morphology-Cosmology Connection for X-Ray-Clusters
(Univ Chicago Press, 1993-12-10)
We employ N-body/three-dimensional gasdynamic simulations of the formation of galaxy clusters to determine whether cluster X-ray morpholgies can be used as cosmological constraints. Confirming the analytic expectations of ...
