Detection and prevention of hepatitis C in dialysis patients and renal transplant recipients. A long-term follow up (1989-january 1997)

Background. Hepatitis C is frequent problem in dialysis wards. Design. A long time (1989-97) follow up of hepatitis C virus (HCV) infection in a Swedish nephrology unit was performed with anti-HCV screening, confirmatory antibody tests, viral RNA detection and molecular characterization. Case histories were reviewed with focus, onset of infection, liver morbidity and mortality. Results. In October

Relationship of airway responsiveness to agents causing bronchoconstriction and cough in sensitized guinea-pigs

The relationship between airway responsiveness to bronchoconstrictor- and cough-inducing stimuli has been examined in Ascaris suum-sensitized conscious guinea-pigs. Guinea-pigs were sensitized to Ascaris suum [4000 PNU and 100 mg Al(OH)3 i.p. on days 1 and 7] and then challenged with aerosolized antigen on days 21, 28 and 35. At day 35, antigen-exposure produced an early bronchoconstrictor respons

Safe Reference Following on the Inverted Pendulum

This work discusses methods to obtain reference following on unstable systems. The task is critical; introduction of refernce signal might cause instability in some cases. It is thus interesting to develop strategies that offer acceptable reference following, but also guarantees stability. In practice similiar problems arises in flight control systems for unstable fighter aircrafts. Experimental v

Wave Splitting in Direct and Inverse Scattering Problems

The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. Several different wave splittings are studied including one-dimensional, multi-dimensional energy-flux, and multi-dimensional locally exact wave splittings. The Bremmer series is

Amphiphilic anthracene-amino acid conjugates as simple carbohydrate receptors in water

N-Alkylation of amino acid methyl esters with 9,10-bis-chloromethylanthracene, followed by methyl ester hydrolysis, yielded water-soluble amphiphilic amino acid-anthracene conjugates. In NMR-titration experiments, a L-arginine-anthracene conjugate was demonstrated to recognize p-nitrophenyl glycosides and sialylated oligosaccharides in D2O in a manner sensitive to the carbohydrate structure.

Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

Popular Abstract in Swedish The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. As anThe problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure.

Elemental composition of ectomycorrhizal mycelia identified by PCR-RFLP analysis and grown in contact with apatite or wood ash in forest soil

The aim of this study was to identify ectomycorrhizal species with a potential to release elements from apatite and wood ash and accumulate them in the mycelia. Fungal rhizomorphs and mycelia were sampled from sand-filled mesh bags with or without amendment of apatite or wood ash. The mesh bags were buried in forest soil in the field for 13 or 24 months. Elemental composition of the samples was an

EKO-Energi - a public voluntary programme targeted at Swedish firms with ambitious environmental goals

A total of 47 firms joined the Swedish EKO-Energi programme between 1994 and 1997. This was a public voluntary programme devoted to promoting the environmental vanguard, while disregarding the rearguard. The programme offered free energy audits and the promotion of a label, in return for implementation of energy management. Audits covered some 5% of industrial energy consumption. The most clearly
