Mutations in carbohydrate-negative mutants of Pseudomonas aeruginosa PAO1 individually deficient in glucose 6-phosphate dehydrogenase (zwf), 6-phosphogluconate dehydratase (edd), or pyruvate carboxylase (pyc) were mapped on the chromosome by plasmid R68.45-mediated conjugation and by bacteriophage F116L-mediated transduction. Loci for all three genes were located in the 45- to 55-min region of ...

The length of stay for moderately preterm infants has progressively become shorter in the UK in recent years but staff still commonly inform parents that their baby will go home around their estimated date of delivery (EDD). Parents need as much notice as possible to prepare for the discharge of their baby, and to gain the necessary skills and knowledge to care for their infant safely. We repor...

This paper identifies two different parametrized dynamic priority queue disciplines, earliest due date (EDD) based and head of line priority jump (HOL-PJ), which are found to be mean waiting time complete in two class M/G/1 queue. An explicit one-to-one non linear transformation is obtained between earliest due date and delay dependent priority policy. Mean waiting time equivalence between thes...

Real-time video demands a stringent delay and jitter requirement. A switch in the network needs to implement an effective scheduling algorithm to meet such a requirement. The Jitter-EDD (Earliest-Due-Date) scheme designed for packet switching networks is noted for its capability to control the end-to-end delay jitter to be within the delay variation in the last switching node of the path. It, h...

Recently, a novel PCR-based technique, differential display (DD), has facilitated the study of differentially expressed genes at the mRNA level. We report here an improved version of DD, which we call Enhanced Differential Display (EDD). We have modified the technique to enhance reproducibility and to facilitate sequencing and cloning. Using EDD, we have generated and verified a catalog of gene...

M-mode echo recordings of the left ventricle (LV) and inflow LV Doppler velocimetry were performed in nine normal fetuses at a gestational age of 36-39 weeks. In each fetus approximately 80 consecutive cardiac cycles were digitized. The duration of each cardiac cycle (T) and the corresponding end-diastolic (EDD), end-systolic (ESD) dimensions of LV or the peak velocity of early (E) and late atr...
