This chapter discusses different coals compared with respect to the extent of sulfur removal and jarosite formation when processed with A. brierleyi. All coals are of low-sulfur type with a sulfur content ranging from 0.6 % through 1.8 %. The efficiency of the microbial processing of coal depends on three factors––namely, the rate of sulfur removal, the extent of sulfur removal, and the formation
The construction of a magnetron-based source for neutral metal vapors is presented. The first photoelectron spectroscopy experiments with the source using synchrotron radiation at MAX-lab, Sweden are described. Photoelectron spectra of atomic copper, silver, and nickel are reported with an 80 meV resolution for Cu and Ag, previously not achieved in experiments using synchrotron light. (c) 2006 Ame
A model has been developed to predict the dissolution rate of a limestone slurry as a function of particle size distribution and limestone conversion. The model is based on basic mass-transfer theory and includes a factor allowing the flux of calcium ions from the limestone surface to vary with the fraction dissolved. Changes in the flux with the fraction dissolved have been reported to be caused
OBJECTIVE. To identify markers for late fetal death, a multicenter study was performed, based on routinely obtained data from maternal health care units. MATERIAL AND METHODS. Prospectively recorded data were obtained from maternal health care units belonging to five delivery units. In all, 233 consecutive cases of singleton pregnancy involving late fetal death (> or = 28 weeks) were identified be
Vascular smooth muscle phenotype is regulated by environmental factors, such as mechanical forces, which exert effects on signaling to differentiation and growth. We used the mouse portal vein in organ culture to investigate stretch-dependent activation of Akt, extracellular regulated protein kinase (ERK) and focal adhesion kinase (FAK), which have been suggested to be involved in the regulation o
A need for methods to assess fire risks in timber frame buildings lead to the development of FRIMMAB, a Fire Risk Index Method for Multi-storey Apartment Buildings. The main objective of this report is to evaluate this method against a different risk analysis method, in this case a standard QRA (quantitative risk analysis) based on an event tree. Four different multi-storey apartment buildings in
Abstract in French Au-delà du montage – la rhétorique du cinéma Contrairement à d'autres types d'images plus statiques, le film, avec son fort "effet de réalité", semble résister à une explication inspirée d'un modèle rhétorique. Même du point de vue d'une rhétorique "écologique", telle que la nôtre, qui reconnaît une rupture de normes déjà dans les transformations homogènes, le film peut facilem
There currently exists legislation within Europe banning the use of dyestuffs based on certain carcinogenic amine compounds. Currently a test method exists that is used by the industry (CEN ISO TS 17234 based on DIN 53316). This is able to detect twenty of the compounds listed by the legislation but is not validated for the recently added 2-methoxyaniline and is unsuitable for analysis of -Aminoaz
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
Essä om blockbusterfilmens 1970-tal och början på den filmstil och marknadsföringsstrategi som kallats high concept.
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
