Pressure ulcers are localized areas of soft tissue breakdown due to mechanical loading. Susceptible individuals are subjected to pressure relief strategies to prevent long loading periods. Therefore, ischemia-reperfusion injury may play an important role in the etiology of pressure ulcers. To investigate the inter-relation between postischemic perfusion and changes in skeletal muscle integrity,...

The present study examined the modality specificity and spatio-temporal dynamics of "what" and "where" preparatory processes in anticipation of auditory and visual targets using ERPs and a cue-target paradigm. Participants were presented with an auditory (Experiment 1) or a visual (Experiment 2) cue that signaled them to attend to the identity or location of an upcoming auditory or visual targe...

Using a speeded lexical decision task, event-related potentials (ERPs), and minimum norm current source estimates, we investigated early spatiotemporal aspects of cortical activation elicited by words and pseudo-words that varied in their orthographic typicality, that is, in the frequency of their component letter pairs (bi-grams) and triplets (tri-grams). At around 100 msec after stimulus onse...

This work was conducted as an activity under the Radionuclide Transport (RT) Key Technical Issue (KTI). In the current U.S. Department of Energy (DOE) Total System Performance Assessment (TSPA) for the proposed Yucca Mountain high-level nuclear waste repository, Tc-99 has consistently represented a significant proportion of the dose to the critical group. This is due to the high solubility and ...

INTRODUCTION Zygomatic fractures form a major entity in craniomaxillofacial traumatology. Few studies have dealt with biomechanical basics and none with the role of the facial soft tissues. Therefore this study should investigate, whether facial soft tissue plays a protecting role in lateral midfacial trauma. METHODS A head-to-head encounter was simulated by way of finite element analysis. In...

the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...

Xiaohui Xue Dept. of Computer Science, Harbin Institute of Technology, Harbin, Heilongjiang, P.R.China [email protected] The mainstream of image compression research has been based on the Shannon Information Theory for years. In image data, there exist statistical redundancy, knowledge redundancy and psychophysiological redundancy, and the latter two cannot be handled by Shannon theory. Th...

results the mean qtc at baseline (pre-methadone) was 426 ± 34 msec and after being on methadone for an average of 8.72 ± 4.50 years was significantly higher at 450 ± 35 msec. no significant relationships were found between qtc prolongation and risk factors except for calcium. the methadone dosage was significantly higher in veterans with a qtc change above the mean change of ≥ 24 msec (88.48 ± ...
