Novel Measurements in Primary Settling Tanks of Large Municipal Wastewater Treatment Plants

Abstract

This paper shows the in situ analysis of a primary settling tank (PST) at the Graz Municipal Wastewater Treatment Plant (500 000 PE). The study aims at the deeper understanding of primary settling tanks behaviour by measurement of flow pattern within the tank and suspended solids (SS) separation.

Measurement campaigns were carried out at different surface overflow rates (a main measure of PST load), that ranged from low to even higher values than recommended ones by design guidelines. During the measurements the inflowing and outflowing SS concentrations and loads were registered on-line. The flow pattern (3D velocity measurements, turbulence characteristics) was measured by using Acoustic - Doppler - Velocimetry (ADV) in raster [1]. The settling function was carried out by laboratory test at Budapest Central Wastewater Treatment Plant, which was investigated at representative concentration of PST.

The measurements provided detailed insight into the flow and mass transport processes within the PST and valuable calibration and verification data for further CFD modelling.

Unsettling Melodies: a Cognitive Approach to Incongruent Film Music

Abstract

Incongruent film music is a soundtrack, either diegetic or nondiegetic, which expresses qualities that stand in contrast to the emotions evoked by the events seen. The present article aims at covering two interconnected areas; the first is comprised of a critical recapitulation of available theoretical accounts of incongruent film music, whilst the second part of the paper offers an alternative, embodied-cognitive explanation of the audio-visual conflict which arises from this particular type of incongruence. Rather than regarding it as a phenomenon that works through disrupting conventions, we stress a perceptual-cognitive reason behind incongruence’s emotional strangeness.

Last Year at Mulholland Drive: Ambiguous Framings and Framing Ambiguities

Abstract

This article proposes a cognitive-narratological perspective on David Lynch’s Mulholland Drive (2001) and the numerous contrasting interpretations that this film has generated. Rather than offering an(other) interpretation of the film, we aim to investigate some of the reasons why Lynch’s highly complex narrative has gained a cult – if not classic – status in recent film history. To explain the striking variety of (often conflicting) interpretations and responses that the film has evoked, we analyse its complex narrative in terms of its cognitive effects. Our hypothesis is that part of Mulholland Drive’s attractiveness arises from a cognitive oscillation that the film allows between profoundly differing, but potentially equally valid interpretive framings of its enigmatic story: as a perplexing but enticing puzzle, sustained by (post-)classical cues in its narration, and as an art-cinematic experience that builds on elements from experimental, surrealist, or other film- and art-historical traditions. The urge to narrativize Mulholland Drive, we argue, is driven by a distinct cognitive hesitation between these conflicting arrays of meaning making. As such, the film has been trailblazing with regards to contemporary cinema, setting stage for the current trend of what critics and scholars have called complex cinema or puzzle films.

Sources of variation in haematocrit in the Collared Flycatcher (Ficedula albicollis)

Abstract

The haematocrit rate of the blood shows the individual physiological state. As the haematocrit grows, the higher erythrocyte number results in more efficient oxygen uptake capacity which can lead to better performance and probably a better survival rate of an individual. Hence we assume that the high value of haematocrit reflects good health state. Altogether 308 blood samples were collected from a wild population of Collared Flycatchers (Ficedula albicollis) in two breeding stages during a period of 2008-2010. We tried to elucidate the relationship between condition and haematocrit level of an individual and studied the haematocrit changes of an individual between years. The haematocrit values differed between years. Females had higher haematocrit values than males in 2010 but not in 2009. At courtship the haematocrit level of males was higher, than during nestling care. The different environmental effects and energy demands of the individuals may be the driving force behind the observed changes in haematocrit level. Analysing the changes between two years, there was a positive correlation between changes in condition index and haematocrit of individuals. The haematocrit values of an individual were repeatable between years. This finding suggests that haematocrit can be informative about the individual’s general health state.
