A 43-L column photobioreactor wash tested for the treatment of acetonitrile Using a symbiotic consortium consisting of a Chlorella sorokiniana strain and a Comamonas strain. Complete biodegradation of 1 g acetonitrile/l was achieved in 79 hours under continuous illumination at 500 mu E/m(2) s and 26 degrees C. When the photobioreactor was operated at 26 degrees C under a 14/10 hours light/dark ill

A general model for pressure drop calculations in siphons and riser tubes has been developed. The model takes into account different physical flow phenomena such as inlet pressure drop and pressure drop in the tube. For each phenomenon, we applied theory and established correlations to calculate the separate accelerational, frictional, gravitational, and centrifugal pressure drops. Model results a

Uttorkning av betong är ett ämnesområde som under lång tid varit i fokus. Genom åren har många skadefall kunnat kopplas till alltför fuktiga betonggolv. Det är inte betongen som tar skada utan vissa material som placerats i direkt anslutning till betongen. Exempel är kemisk nedbrytning av lim under plastmattor, vilket skapat kemiska emissioner som vandrat ut till inomhusluften, eller som lett till

While populism and populist politics have been the focus of a wide range of studies in the social sciences, few analyses of populist phenomena have moved beyond the level of simple description. This study has three immediate aims: to critique existing theories of populism, to develop a new, analytical view of populism, and apply this view comparatively to two cases. This new view of populism emer

Chromatofocusing of proteins in a microcolumn format (750 mum i.d.) was evaluated with slurry-packed Mono P anion-exchanger beads (10 pin bead size) as chromatographic matrix. Evaluation was performed with three standard proteins in terms of flow rate, Polybuffer 96-acetic acid, pH 6.0, concentration (eluent buffer strength), and detection limit. A column with the dimension 750 pin i.d. x 50 mm le

OBJECTIVE: Self-rated health (SRH) is increasingly attracting attention as a predictor of morbidity and mortality while its relation to impaired function has been given less momentum. The aim of this study was to assess the relation between SRH and the risk of being awarded a disability pension and premature death. METHODS: Five birth-year cohorts of middle-aged men were invited to a screening pro

Parmelia ernstiae Feuerer & A. Thell, recently described from northwestern Germany, is reported from one locality in central Skåne, southernmost Sweden.

A search for the single production of doubly-charged Higgs bosons H-+/-+/- in ep collisions is presented. The signal is searched for via the Higgs decays into a high mass pair of same charge leptons, one of them being an electron. The analysis uses up to 118 pb(-1) of ep data collected by the H1 experiment at HERA. No evidence for doubly-charged Higgs production is observed and mass dependent uppe

Telomerase Repeat Amplification Protocol (TRAP) in situ was performed on cytospin preparations from 65 effusions from the serous cavities (45 pleural and 19 ascitic fluids and one pericardial fluid) submitted for routine diagnosis and the results were correlated to cytological morphology. Three types of cells with nuclear fluorescence were identified: malignant cells, hyperplastic mesothelial cell

Comparisons of PIXE detection limits for K, X rays using 2-5 MeV protons and 7-8 MeV 4He2+ ions as projectiles have been performed. The comparisons have been made for common aerosol backings. According to simple theoretical considerations regarding X-ray production cross sections and the production of background radiation, detection limits for 4He2+ should be two to four times lower than for proto
