Scireader Enables Reading Of Medical Content With Instantaneous Definitions, Patrick R. Gradie, Megan Litster, Rinu Thomas, Jay Vyas, Martin Schiller

Life Sciences Faculty Research

Background

A major problem patients encounter when reading about health related issues is document interpretation, which limits reading comprehension and therefore negatively impacts health care. Currently, searching for medical definitions from an external source is time consuming, distracting, and negatively impacts reading comprehension and memory of the material.

Methods

SciReader was built as a Java application with a Flex-based front-end client. The dictionary used bySciReader was built by consolidating data from several sources and generating new definitions with a standardized syntax. The application was evaluated by measuring the percentage of words defined in different documents. A survey was used …

Abundance And Size Of Quagga Mussels (Dreissena Bugensis) Veligers In Lake Mead, Nevada-Arizona, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong

Environmental & Occupational Health Faculty Publications

The planktonic veligers of the invasive quagga mussel were present year-round from April 2008 to March 2009 in Lake Mead, with high abundance from September to October (>20 veligers/L), whereas the percentage of competent veligers, in terms of the ability to settle, peaked from November 2008 to January 2009 (>60%). The results from this experiment are useful in understanding the life history and population dynamics of quagga mussels in the lower Colorado River Basin.

Quagga Mussels In The Western United States: Monitoring And Management, Wai Hing Wong, Shawn Gerstenberger

Environmental & Occupational Health Faculty Publications

Dreissenid mussels including zebra mussel (Dreissena polymorpha Pallas, 1771), originating from the Ponto-Caspian area, and quagga mussel (Dreissena rostriformis bugensis Andrusov, 1897), originating from the mouths of the Rivers Southern Bug and Dnieper are both species native to Eastern Europe, which were accidently introduced into the Laurentian Great Lakes in North America in the 1980s in ballast water (Carlton 2008; Van der Velde et al 2010). Dreissenid mussels have created severe ecological, recreational and economic impacts on many systems because they are biofoulers and efficient ecological engineers that filter large quantities of water. Examples of these wide-ranging impacts are discussed …

The 100th Meridian Initiative At The Lake Mead National Recreation Area, Nv, Usa: Differences Between Boater Behaviors Before And After A Quagga Mussel, Driessena Rostiformis Bugensis, Invasion, Sara Ann Mueting, Shawn Gerstenberger

Environmental & Occupational Health Faculty Publications

The 100th Meridian Initiative was developed to help prevent the spread of aquatic nuisance species (ANS) through boater education and research on boater movement patterns and behaviors. Surveys employing these elements were conducted at Lake Mead National Recreation Area (LMNRA) in 2002-2003 before the discovery of the quagga mussel (Dreissena rostiformis bugensis Andrusov 1897) and in 2007-2008 after an established population of quagga mussels was found in the Lake. Boaters were asked questions in a personal interview or a mail-in survey regarding what body of water they had previously launched their watercraft in, where they were planning to launch next, …

Interagency Monitoring Action Plan (I-Map) For Quagga Mussels In Lake Mead, Nevada-Arizona, Usa, Kent Turner, Wai Hing Wong, Shawn Gerstenberger, Jennell M. Miller

Environmental & Occupational Health Faculty Publications

Following the discovery of quagga mussels in Lake Mead, Nevada-Arizona, USA, a variety of federal, state and regional agencies set up monitoring programs to evaluate and gain information to help minimize the impacts, or potential impacts, of quagga mussels to their facilities and lake ecology. While the agencies have worked closely and shared monitoring data and findings from the beginning of the infestation, there has been no documented comprehensive monitoring program to describe and record the various quagga mussel-related monitoring needs. Ad hoc interagency quagga mussel meeting representatives established an Interagency Monitoring Action Plan (I-MAP), which outlines agency objectives related …

Abundance And Stomach Content Analysis Of Threadfin Shad In Lake Mead, Nevada: Do Invasive Quagga Mussels Affect This Prey Species?, Eric Michael Loomis, Jon C. Sjoberg, Wai Hing Wong, Shawn Gerstenberger

Environmental & Occupational Health Faculty Publications

Lake Mead, Nevada is the largest reservoir by volume in the United States, as well as a popular sport fishing destination. In January 2007, the invasive quagga mussel Dreissena rostriformis bugensis (Andrusov, 1897) was discovered in the reservoir and concerns began to arise about potential alterations to the aquatic environment. The Lake Mead sport fishery is reliant on the sustainability of prey species like the threadfin shad [Dorosoma petenense (Günther, 1867)]. This study examined 20-year trends in historic abundance of the threadfin shad, before, and shortly after, the discovery of quagga mussels in the system. Larval shad trawl data collected …

Environmental Factors Affecting Settlement Of Quagga Mussel (Dreissena Rostriformis Bugensis) Veligers In Lake Mead, Nevada-Arizona, Usa, Dong Chen, Shawn Gerstenberger, Sara Ann Mueting, Wai Hing Wong

Environmental & Occupational Health Faculty Publications

Environmental factors that can affect the settlement rate of quagga mussel veligers include flow velocity, water temperature, pH, dissolved oxygen (DO), conductivity, total organic carbon (TOC), and the surface roughness of monitoring substrates. In the present study, six artificial substrates, Acrylonitrile Butadiene Styrene (ABS) plastic, High Density Polyethylene (HDPE) plastic, Concrete Underlayment Board (CUB), aluminum, stainless steel and fiberglass, were used to monitor the settlement of quagga mussel veligers at different water depths in Lake Mead, Nevada-Arizona, USA. Considering the hierarchical data structure of observed mussel densities, we investigated the relationship between mussel settlement on monitoring substrates and the surrounding …

A Standardized Design For Quagga Mussel Monitoring In Lake Mead, Nevada-Arizona, Wai Hing Wong, Shawn Gerstenberger, Jennell M. Miller, Craig Palmer, Bryan Moore

Environmental & Occupational Health Faculty Publications

The discovery of quagga mussels (Dreissena rostriformis bugensis) in Lake Mead, Nevada-Arizona, on January 6, 2007 is the first known occurrence of dreissenid species in the western United States. This study developed elements of a cost-effective and standardized quagga mussel-monitoring program for Lake Mead using preliminary data to arrive at statistically based numbers of sampling sites. To represent the abundance of adult/juvenile quagga mussels in Lake Mead’s heterogeneous floor with 95% confidence, a stratified simple random sampling design revealed a requirement of 41 samples from hard substrates (i.e., rocky areas) and 97 samples from soft substrates (i.e., sandy and muddy …

Settlement And Growth Of Quagga Mussels (Dreissenia Rostriformis Bugensis Andrusov, 1897) In Lake Mead, Nevada-Arizona, Usa, Wai Hing Wong, Shawn Gerstenberger, Wen Baldwin, Bryan Moore

Environmental & Occupational Health Faculty Publications

Settlement and growth of quagga mussels Dreissena rostriformis bugensis were monitored in Lake Mead, NV, USA, where the first dreissenid occurrence was confirmed in the western United States. To measure the settlement rate of these invasive mussels, seven acrylonitrile butadiene styrene (ABS) pipes were attached to a line in shallow water (7.7 m below the surface) since November 23, 2007; eight ABS pipes were placed on another line in deep water (13.4 m below the surface) since January 3, 2008. Quagga mussels were sampled from these pipes on March 19, May 21, July 9, October 20, and December 19, 2008. …
