BACKGROUND AND PURPOSE Dynamic methods of measuring cerebral autoregulation have become an accepted alternative to static evaluation. This article aims to describe a set of data collected from healthy volunteers by a dynamic method, the purpose being to qualify and quantify expected results for those who may be designing a study using this technique.

The widespread use of mobile devices, particularly by young people, offers new and exciting possibilities for learning. The mobility and pervasiveness factors inherent to mobile technologies allow support for learning at any time and in any place. A common problem among young undergraduate students is that many are disinterested in learning. Often very(More)
In vitro L-arginine enhanced natural-killer (NK) and lymphokine-activated-killer (LAK) cell activity; this cytotoxicity was mediated by CD56+ cells. In vivo arginine supplements (30 g/day for 3 days) increased the number of circulating CD56+ cells by a median of 32% in eight volunteers (p less than 0.01); this increase was associated with a mean rise of 91%(More)
Carotid endarterectomy has been shown to reduce the long-term risk of stroke in selected patients. The present study was designed to examine cognitive function and health related quality of life in a series of carotid endarterectomy patients. One hundred and nine patients undergoing carotid endarterectomy were assessed before surgery and at 6 months post op(More)
Text messaging has been exploited for supporting learning in a variety of educational settings. However, evidence for its effectiveness and impact is limited. This chapter demonstrates how the use of text messaging can contribute towards enhanced quality of learning. In particular the chapter focuses on the use of text messaging as a means of improving(More)
A. COMPUTER SYNTHESIZED TWO EXPERIMENTS HOLOGRAMS-In a previous report, we derived a new method for recording a complex function in the form of a real non-negative function. The new method has advantages over the conventional holographic method because it does not require a reference signal or a biasing constant in recording the complex wave front of an(More)
