Moving bed biofilm reactors (MBBRs) were placed at two wastewater treatment plants, where they constantly fed with effluent and intermittently primary wastewater. Each reactor was subjected to different feast/famine periods flow rates of wastewater, thus the organic nutrient loads (chemical oxygen demand(COD), ammonium(NH4-N)) resulted in feast-famine conditions applied biomass. In batch experi...

We report on our experiences with integrating GPUs as fast, parallel floating-point coprocessors into the parallel FE package FEAST. Since a full re-implementation of such a package is not feasible, we identify the smoothing of an outer domain-decomposition multigrid solver as a natural entry-point for a minimally invasive integration of GPUs. We address the issue of limited computational preci...

Mild iodine deficiency is a recognised problem in Australia and New Zealand. However, iodine excess can cause hypothyroidism in some infants. We highlight two cases which illustrate the risks of excess dietary iodine intake during pregnancy and breastfeeding. They also describe a cultural practice of consuming seaweed soup to promote breast milk supply. Although most attention recently has been...

"The musically aware hostess no longer allows the butler, or her husband, to sling records on to the turntable in a haphazard way. She no longer risks the dangers of the soup being spilled by Haydn's 'Surprise' Symphony, or Mrs. Alias-Jones choking over the fish because an ill-timed bit of jazz trumpet has frightened her. She now supplies a ready-made background of elegant and suitable music to...

The past 25 years have seen major advances in software engineering. The power, sophistication and ease of use of systems are constantly increasing. Systems that only a few years ago presented a major challenge are now developed as a matter of routine. Improvement of the overall process of software development has, however, proved slow and difficult, both in comparison to hardware and when judge...

Faithfully participating in the Eucharist has been a struggle for body of Christ since formation Church (I Cor 11:17-34). According to Paul, Eucharist, as cruciform meal was intended perform socializing dynamics that pushed against rather than reinforced social fragmentation and marginalization within Corinthian (Gerd Theissen Mark T. Finney). The offered church Corinth way enable boundaries by...

The 87 new 0 determinations were added to the existing sample of cepheids with known radial velocities, forming an extended sample of 278 galactic classical cepheids with reliable radial velocity and photometry. We then calculated distances for these objects through a Period-Luminosity-Colour relation due to Feast & Walker (1987). The position of the cepheids in the galactic disk as given by th...
