Nondestructive techniques to obtain DNA from organisms can further genetic analyses such as estimating genetic diversity, dispersal and lifetime fitness, without permanently removing individuals from the population or removing body parts. Possible DNA sources for insects include frass, exuviae, and wing and leg clippings. However, these are not feasible(More)
Object-oriented systems development (OOSD) is a recent innovation in software development that is often cited as a viable solution to many of the ills plaguing this critical industry. However, some express doubt about the potentially over-hyped claims of OOSD. While there are many accounts of the successful application of OOSD, widespread acceptance has not(More)
BACKGROUND/AIMS Telemedicine offers potential to improve the accessibility and quality of diagnosis of retinopathy of prematurity (ROP). The aim of this study was to measure accuracy of remote image based ROP diagnosis by three readers using receiver operating characteristic (ROC) analysis. METHODS 64 hospitalised infants who met ROP examination criteria(More)
Infection of quiescent fibroblasts with human cytomegalovirus (HCMV) was found to cause a rapid activation of cellular phosphatidylinositol 3-kinase (PI3-K). Maximum PI3-K activation occurred from 15 to 30 min postinfection. This activation was transient, and by 2 h postinfection (hpi), PI3-K activity had declined to preinfection levels. However, at 4 hpi,(More)
The Alexandria Digital Earth Prototype (ADEPT) Project (1999--2004) builds upon the Alexandria Digital Library Project (1994--1999) to add functions and services for undergraduate teaching to a digital library of geospatial resources. The 'Digital Learning Environment' (DLE) services are being developed and evaluated iteratively over the course of this(More)
