This paper deals with an almost 1-year long pilot study of a nitritation-denitritation process that was followed by anammox polishing. The pilot plant treated real municipal wastewater at ambient temperatures. The effluent of high-rate activated sludge process (hydraulic retention time, HRT=30 min, solids retention time=0.25 d) was fed to the pilot plant described in this paper, where a constan...

Studies suggest that the Southeast is an area of primary concern with regards to the spread of alien plant species (Miller 2003, Stapanian and others 1998). Data collected by Stapanian and others in 1998 showed that Japanese honeysuckle (Lonicera japonica) occurred over 2 million acres in the Southeast, invading forests and displacing native species. Among the most important mechanisms for the ...

The Beaudesert Sewage Treatment Plant (STP), originally built in 1966 and augmented in 1977, is a typical biological trickling filter (TF) STP comprising primary sedimentation tanks (PSTs), TFs and humus tanks. The plant, despite not originally being designed for nitrogen removal, has been consistently achieving over 60% total nitrogen reduction and low effluent ammonium concentration of less t...

108 INTRODUCTION Altruistic behaviours have been the object of abundant theoretical and empirical social science research for some thirty years (Chac—n, 1985, Piliavin and Charng, 1990). In this field there are two tendencies that have captured the majority of research attention. The first of these is represented by unexpected situations in which help is offered to strangers, reflecting the alt...

Researchers at Washington State University conducted an independent evaluation of the first year of the Washington State Early Childhood Education Career and Wage Ladder Pilot Program. The evaluation, which compared ladder centers with a control group, verified that the career and wage ladder works to improve the quality of early childhood education by reducing teacher turnover and encouraging ...

Figure 1. PILOT telescope, enclosure and tower INTRODUCTION PILOT (The Pathfinder for an International Large Optical Telescope) is a 2.4m optical/infrared telescope, proposed for Dome C on the Antarctic Plateau, with target first light at the end of 2012.

Abstract. A pilot plant for treating 1,000m of textile dyeing wastewater per day with electron beam has constructed and operated continuously in Daegu, Korea since 1998. This plant is combined with biological treatment system and it shows the reduction of chemical reagent consumption, and also the reduction in retention time with the increase in removal efficiencies of CODCr and BOD5 up to 30~4...

Scientific problems that depend on processing large amounts of data require overcoming challenges in multiple areas: managing large-scale data distribution, controlling co-placement and scheduling of data with compute resources, and storing, transferring, and managing large volumes of data. Although there exist multiple approaches to addressing each of these challenges and the complexity of dis...

Creativity can be understood in analogous ways across both arts and sciences. A central component of artistic creativity is the ability to generate many different expressions. Scientific creativity involves the ability to generate various novel solutions to problems. This means a possible way to augment creativity in both arts and science is to seek to increase our ability to generate many expr...
