A theoretical basis is required for comparing key features and critical elements in wild fisheries and aquaculture supply chains under a changing climate. Here we develop a new quantitative metric that is analogous to indices used to analyse food-webs and identify key species. The Supply Chain Index (SCI) identifies critical elements as those elements with… (More)
Significant research efforts are underway to investigate the application of Free-Space Optics (FSO) for the provision of high-bandwidth communications links between mobile platforms. The use of FSO between mobile platforms introduces several interesting challenges in addition to those found in traditional fixed link FSO systems. In this paper, some of the… (More)

Why is there no Nobel Prize in nursing? The question was posed last month in the Baltimore Sun, after the presentation of the 2006 Nobel Prize in Physiology or Medicine.
Bucrylate was injected directly into the cerebral cortical arteries of mongrel dogs. Preparations for light and electron microscopy were obtained from 5 min to 5 months after the introduction of the polymer. A mixed pattern of damage to arterial endothelium was seen, including electron microscopic documentation of stripping away of the endothelium. Acute… (More)
In the evaluation of a large series of infectious processes in the cervical region, certain diagnostic sonographic patterns have been established, which prove very helpful in differentiating the various stages and the extension of inflammatory processes. The advantages of sonographic imaging are demonstrated.
