Activated sludge not containing significant numbers of denitrifying, polyphosphate [poly(P)]-accumulating bacteria was grown in a fill-and-draw system and exposed to alternating anaerobic and aerobic periods. During the aerobic period, poly(P) accumulated up to 100 mg of P · g of (dry) weight. When portions of the sludge were incubated anaerobically in the presence of acetate, 80 to 90% of the int

In acetate-limited chemostat cultures of Acinetobacter johnsonii 210A at a dilution rate of 0.1 h−1 the polyphosphate content of the cells increased from 13% to 24% of the biomass dry weight by glucose (100 mM), which was only oxidized to gluconic acid. At this dilution rate, only about 17% of the energy from glucose oxidation was calculated to be used for polyphosphate synthesis, the remaining 83

The formation process of binary clusters has been studied using synchrotron based core level photoelectron spectroscopy. Free neutral krypton clusters have been produced by adiabatic expansion and doped with chloromethane molecules using the pickup technique. The comparison between the integrated intensities, linewidths, and level shifts of the cluster features of pure krypton and of chloromethane

The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. The clusters studied in this work are constituted by rare-gas atoms, organic

Healthcare databases are unique tools in public health research to evaluate the healthcareperformance and treatment compliance. Knowledge about the data quality is required toenable interpreting the results from statistical analyses. We summarize different samplingmethods suitable for the validation of healthcare databases and discuss their advantages anddisadvantages.You will learn from the prese

Health care organizations are under increasing pressure to account for their performance to outside constituencies. This chapter reviews the background, nature, and consequences of organized efforts to enhance transparency in health care. Market reforms and quality concerns create mounting demands for public transparency, but health care quality is difficult to assess in a way that is both fair an

This article is concerned with how we make decisions based on how problems are presented to us and the effect that the framing of the problem might have on our choices. Current philosophical and psychological accounts of the framing effect in experiments such as the Asian Disease Problem (ADP) concern reference points and domains (gains and losses). We question the importance of reference points a

This study analyses the effect of pictures in reading materials on the viewing patterns of dyslexic adults. By analysing viewing patterns using eye-tracking, we captured differences in eye movements between young adults with dyslexia and controls based on the influence of reading skill as a continuous variable of the total sample. Both types of participants were assigned randomly to view either te

The paper presents results from a comparative study of selected biological and technical functions for thermal adaptability, which are based on an extensive literature review in biology and façade engineering. Several selected biological role models have been analysed in detail to identify their principles for dealing with thermal adaptation. These principles have been further abstracted through s
