Pilot-scale surface-flow (SF), subsurface-flow (SSF), and floating aquatic plant (FAP) constructed wetland system designs were installed and evaluated to determine the effectiveness of constructed wetlands to treat tertiary effluent wastewater in a Midwestern U.S. climate (central Illinois). Average ammonia-nitrogen (N) concentrations decreased(More)
Valvular heart disease is a major cause of morbidity and mortality in developing and industrialized countries. For patients with advanced symptomatic disease, surgical open-heart valve replacement is an effective treatment, supported by long-term outcome data. More recently, less-invasive transcatheter approaches for valve replacement/implantation have been(More)
BACKGROUND Human embryonic stem cells (hESCs) have been derived and maintained on mouse embryonic fibroblast feeders to keep their undifferentiated status. To realize their clinical potential, a feeder-free and scalable system for large scale production of hESCs and their differentiated derivatives is required. MATERIALS & METHODS hESCs were cultured and(More)
The Science of Security, particularly in the case of human factors and usability, remains inchoate. Individual research groups and researchers develop code, simulations, instruments, dataset and experimental designs that are either not released with adequate detail for reproducibility or simply not reused beyond the individual research group. Through this(More)
EnvironmEntal HEaltH insigHts 2016:10 Zika virus is named for the Zika Forest in Uganda and was first discovered in 1947 in primates. The first human cases of Zika virus infection were detected in 1952. From about 1960– 1980, human infections occurred across Asia and Africa, although infections were typically mild with limited symptoms. The first major(More)
The paper discusses factors contributing to the problem of preparing present and future teachers to accept and become skilled in the use of computers in the instructional process, and the obstacles to achieving a solution.The unique organizational activities of the Oregon Council for Computer Education are presented as a possible solution mechanism. The(More)
The capacity of the Earth's environment to support increasing and expanding human populations has been questioned at least for hundreds of years, but never more than in the mid to late 20th Century and early 21st Century. Global human population now exceeds seven billion and continues to increase at an unprecedented rate. Estimates of future (2050) human(More)
