Microalgae enhance the removal of nutrients, organic contaminants, heavy metals, and pathogens from domestic wastewater and furnish an interesting raw material for the production of high-value chemicals (algae metabolites) or biogas. Photosynthetic oxygen production also reduces the need for external aeration, which is especially advantageous for the treatment of hazardous pollutants that must be

1. The input characteristics and distribution of climbing fibre field potentials evoked by electrical stimulation of various parts of the skin were investigated in the cerebellum of barbiturate anaesthetized rats. 2. Climbing fibre responses were recorded in sagittally oriented microelectrode tracks across the mediolateral width of the anterior lobe. Climbing fibres with similar response latencies

Injury patterns and epidemiologic data from 211 moped accident victims and 214 motorcycle accident casualties admitted to hospital over a 5-year period (1977-1981) have been analyzed and compared. The number of those injured in motorcycle accidents tripled; the number of moped accident victims slightly decreased in the period studied. Differences in injury pattern, sex ratio, cause of accident, an

The paper examines the nonlinear behaviour of one- and two-degree-of-freedom discrete mechanical models subjected to partial follower load under conditions at which divergence instability occurs. Section (1.6) of the paper deals with the dynamic instability of an elastoplastic damped strut compressed by partial follower force at the free end. Space-time curves for the system are presented and disc

One-dimensional propagation of transient EM-waves in periodic media is studied. The media are periodic in the direction of propagation and can be of finite or infinite length. Wave propagators, that map a transient field from one point in the medium to another, are introduced. A number of useful relations for the propagators are presented. Some of these relations are used in the determination of e

Objectives. The aim of the study was to assess long-term state and trait anxiety in cardiac surgical risk patients. Design. Thirty two patients with serum S100B > 0.3 mu g/l 48 hours after cardiac surgery with cardiopulmonary bypass were matched according to age, gender, type, date and length of surgery with 35 operated patients without elevated S100B. They completed Spielberger's Anxiety Inventor

The conjugated polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-pheiiylene vinylene) (MEH-PPV) was studied by a single-molecule imaging technique. A comparison of statistical distributions of fluorescence intensity with molecular weight distributions revealed that the distribution of the photoluminescence quantum yield of the single polymer chains under study is significantly asymmetric, with a pol

Rådgivare som utför sitt uppdrag vårdslöst kan bli ersättningsskyldiga inte bara mot uppdragsgivaren utan också mot tredje man. NJA 1987 s 692.

The X-ray photoabsorption spectra of ZrO2 films with different phase compositions were measured. The analysis of the results obtained shows that due to the site-sensitivity the X-ray photoabsorption spectroscopy is an attractive method for characterization of the ZrO2 structure. This allows application of the X-ray spectroscopy in investigation of the crystal structure in the various stages of the

Intervju med professorn i företagsekonomi, Stefan Yard, om avskrivningen av kärnkraftverken och ekonomin i att lägga ner Barsebäcksverken.

Configuration management (CM) includes synchronizing and supporting developers in their common development and maintenance of a system. In order to utilize personnel regardless of their geographical location, groups of developers are now working all over the world on the development of common systems, a situation called distributed development. From different locations they may need to concurrentl
