In Sweden today, power production with bioenergy systems is more costly than with fossil energy systems. New technology under development, such as integrated gasification and combined cycle technology (IGCC), and reduced biomass costs would improve the competitiveness of bioenergy systems. The CO2 mitigation costs are lower for biomass systems using IGCC technology than for natural gas systems usi
This paper presents a new three-phase liquid-phase microextraction (LPME) strategy for extraction and preconcentration of salbutamol (SB) and terbutaline (TB) from aqueous samples, including urine. The drugs were extracted from I I ml of aqueous sample (source phase; SP) into an organic phase with microliter volume located inside the pores of a polypropylene hollow fiber, and then back-extracted i
Popular Abstract in Swedish Den dramatiska samhällsomvandlingen i Öst- och Centraleuropa 1989-91 förändrade radikalt förutsättningarna för Europas politiska och ekonomiska liv. Den politiska och militära uppdelningen upphörde, gamla stater föll sönder och nya tillkom. I vårt närområde, Östersjöområdet, har förändringarna varit mer genomgripande än på många andra håll. Interaktionen mellan områdetsThe geopolitical transformation after 1989 had radical territorial consequences in almost all parts of East-Central Europe. In the Baltic Sea Area alone, five new states were formed. The process of European integration became a priotity on the agenda. The concept of integration describes a process of uniting two or more entities. Interaction (flows of goods, people and messages) must be seen as a

A sensitive biosensor has been developed for the neurotoxin beta-N-oxalyl-alpha,beta-diaminopropionic acid (beta-ODAP) contained in the seeds of grass pea (Lathyrus sativus) and for L-glutamate based on glutamate oxidase (GlOx) and a Prussian blue (PB) modified glassy carbon (GC) electrode. The configuration of the system is so as to detect the hydrogen peroxide released during the enzymatic cycle
In this work, we describe the application of a sorption calorimeter to study the binary system n-octyl beta-D-glucoside/water at 25, 40, and 60 degreesC. At 25 degreesC we also carried out experiments with heavy water which showed similar results to those with normal water. The method used allows one to simultaneously obtain information about the activity of water and the enthalpy of mixing in bin
A search for events with a high-energy isolated electron or muon and missing transverse momentum has been performed at the electron-proton collider HERA using an integrated luminosity of 13.6 pb(-1) in e(-) p scattering and 104.7 pb(-1) in e(+) p scattering. Within the Standard Model such events are expected to be mainly due to W boson production with subsequent leptonic decay. In e(-) p interacti
The effects of grazing on natural phytoplankton populations was examined during enclosure studies on the effects of nutrients, zooplankton, and ctenophores on phytoplankton bloom dynamics on the west coast of Sweden in May, 1990. Grazers included the copepods Acartia clausi Giesbrecht, Centropages hamatus Lilljeborg, and Oithona similis Claus, and the marine cladoceran Podon polyphemoides Leuckart

Antibody microarray is a novel technology with great promise within proteomics. Intense work is under way to evolve this methodology into the high-throughput proteomic research tool needed by the research community. Despite recent advances, there is a growing need for additional highperformance substrates for antibody microarrays as well as for protein arrays in general. In this study, we have suc
The chapter deals with the problem how history is used to promote a regional consciousness, focusing mainly on the Barents region.
Dust measurements have been obtained with the dust detector onboard the Galileo spacecraft inside a distance of about 60RJ from Jupiter (Jupiter radius, RJ = 71,492 km) during two periods of about 8 days around Galileo's closest approaches to Ganymede on 27 June and on 6 Sept 1996. The impact rate of submicrometer-sized particles fluctuated by a factor of several hundred with a period of about 10
