Silica Content of a Mesohaline Tidal Marsh in North Carolina

In August of 1587 Manteo, an Indian from Croatoan Island, joined a group of English settlers in an attack on the native village of Dasemunkepeuc, located on the coast of present-day North Carolina. These colonists, amongst whom Manteo lived, had landed on Roanoke Island less than a month before, dumped there by a pilot more interested in hunting Spanish prize ships than in carrying colonists to their intended place of settlement along the Chesapeake Bay. The colonists had hoped to re-establish peaceful relations with area natives, and for that reason they relied upon Manteo to act as an interpreter, broker, and intercultural diplomat. The legacy of Anglo-Indian bitterness remaining from Ralph Lane's military settlement, however, which had hastily abandoned the island one year before, was too great for Manteo to overcome. The settlers found themselves that summer in the midst of hostile Indians.

Magnesia partially stabilised zirconia (Mg-PSZ) ceramics are renowned for their excellent nechanical properties. These are effected by processing conditions and purity of starting materials. It has been previously shown that small additions of strontia (SrO) have the effect of removing the major contaminant, silica (SiO2).The mechanism by which this occurs is not fully understood but the strontia appears to form a very mobile liquid phase at the grain boundaries. As the sintering reaches the final stages the liquid phase is expelled to the surface of the ceramic. A series of experiments, to examine the behaviour of the liquid grain boundary phase, were designed to produce compositional gradients across the ceramic bodies. To achieve this, changes in both silica content and furnace atmosphere were implemented. Analytical electron microscope techniques were used to monitor the form and composition of the phases developed. This paper describes the results of our investigation and the presentation will discuss the work with reference to liquid phase sintering of ceramics in general.

This article describes how a telepractice pilot project was used as a vehicle to train first-year graduate clinicians in speech-language pathology. To date, six graduate clinicians have been trained in the delivery of telepractice at The University of North Carolina at Greensboro. Components of telepractice training are described and the benefits and limitations of telepractice as part of clinical practicum are discussed. In addition, aspects of training support personnel involved in telepractice are outlined.

Abstract The AMAGuides to the Evaluation of Permanent Impairment (AMA Guides) is the most widely used basis for determining impairment and is used in state workers’ compensation systems, federal systems, automobile casualty, and personal injury, as well as by the majority of state workers’ compensation jurisdictions. Two tables summarize the edition of the AMA Guides used and provide information by state. The fifth edition (2000) is the most commonly used edition: California, Delaware, Georgia, Hawaii, Kentucky, New Hampshire, Idaho, Indiana, Iowa, Kentucky, Massachusetts, Nevada, North Dakota, Ohio, Vermont, and Washington. Eleven states use the sixth edition (2007): Alaska, Arizona, Louisiana, Mississippi, Montana, New Mexico, Oklahoma, Pennsylvania, Rhode Island, Tennessee, and Wyoming. Eight states still commonly make use of the fourth edition (1993): Alabama, Arkansas, Kansas, Maine, Maryland, South Dakota, Texas, and West Virginia. Two states use the Third Edition, Revised (1990): Colorado and Oregon. Connecticut does not stipulate which edition of the AMA Guides to use. Six states use their own state specific guidelines (Florida, Illinois, Minnesota, New York, North Carolina, and Wisconsin), and six states do not specify a specific guideline (Michigan, Missouri, Nebraska, New Jersey, South Carolina, and Virginia). Statutes may or may not specify which edition of the AMA Guides to use. Some states use their own guidelines for specific problems and use the Guides for other issues.
