Biosensors for measurement of glycerol in FIA were constructed using NAD(+)-dependent glycerol dehydrogenase (GlDH) either co-immobilized with phenazine methosulphate (PMS) or cross-linked to an Os-complex-modified poly(vinylimidazole) redox polymer (PVI(13)dmeOs) using poly(ethyleneglycole) diglycidilether (PEGDGE). The GlDH/PMS sensor was characterized by a linear range of 0.01-1mM glycerol, a s
This paper derives a generic model for the multiple-input multiple-output (MIMO) wireless channel. The model incorporates important effects, including i) interdependency of directions-of-arrival and directions-of-departure, ii) large delay and angle dispersion by propagation via far clusters, and iii) rank reduction of the transfer function matrix. We propose a geometry-based model that includes t
Cold stress effects on the expression of genes for respiratory chain enzymes were investigated in potato (Solanum tuberosum L., cv. Desiree) leaves. The nda1 and ndb1 genes, homologues to genes encoding the non-proton-pumping respiratory chain NADH dehydrogenases of Escherichia coli and yeast, were compared to genes encoding catalytic subunits of the proton-pumping NADH dehydrogenase (complex I).
The condensation energy of homogeneous electron gas is calculated within the density-functional theory for superconductors. Purely electronic considerations include the exchange energy exactly and the correlation energy on a level of the random phase approximation. Singlet superconductivity is assumed, and the Coulomb interaction is studied with a model pairing potential at angular momentum up to

Objectives: To evaluate the use of cellular and cordless telephones as the risk factor For non-Hodgkin's lymphoma (NHL). Methods: Male and female subjects aged 18-74 years living in Sweden were Included during a period from I December 1999 to 30 April 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnalre. Results: In total, 9
Hosts can in principle employ two different strategies to defend themselves against parasites: resistance and tolerance. Animals typically exhibit considerable genetic variation for resistance (the ability to limit parasite burden). However, little is known about whether animals can evolve tolerance (the ability to limit the damage caused by a given parasite burden). Using rodent malaria in labora
Different strategies for reducing emissions of nitrogen oxides and carbon dioxide from the Swedish transportation sector are evaluated by making scenarios for the year 2015, using a bottom-up approach. Methods for reducing emissions of carbon monoxide, hydrocarbons, and sulphur dioxide are discussed more briefly. The scenarios are based on official forecasts of future passenger and goods transport
The objective of this paper is to investigate how the combustion chamber design will influence combustion parameters and emissions in a natural gas SI engine. Ten different geometries were tried on a converted Volvo TD102 engine. For the different combustion chambers emissions and the pressure in the cylinder have been measured. The pressure in the cylinder was then used in a one-zone heat-releas
In order to produce drinking water, coagulants - such as aluminium salts - are widely used for precipitation and separation of impurities from raw water. The residual from the process is sludge, which presents a disposal problem. The REAL process is a method for recycling the aluminium from the sludge. In a first step, the aluminium hydroxide is dissolved in sulphuric acid. In a second step, an ul
Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. However, the field is still open

Rat models are useful for studies of the pathogenesis of rheumatoid arthritis (RA) since rats are extraordinarily sensitive to induction of arthritis with adjuvants. Injection of not only the classical complete Freund's adjuvant but also mineral oil without mycobacteria and pure adjuvants such as pristane and squalene, induce severe arthritis in many rat strains. Models like pristane-induced arthr
This paper presents the findings from a design study of a model-based framework for safety-critical software development, called SimPal. The objective of the study was to better understand the necessary properties of such a framework and to learn more about the challenges of realizing it. Our research approach can be labeled as design research, which means that we try to answer our research questi
We have successfully embedded a metal gate in-between two resonant tunneling double barrier heterostructures (RTD), thus realizing a three dimensional resonant tunneling transistor. The gate is placed 30 nm above and 100 below the two RTD's, respectively. The asymmetric gate allows for a unique control of the current-voltage characteristics, not only controlling the peak current but also the peak
When adapting environments for the physically disabled, it is important to encourage and activate not only the person concerned, but also other people involved or affected. A computer aided planning tool has been developed to support the participation of all persons involved, as well as supporting the planner’s (e.g. an occupational therapist) design of the environment. The prototype development a
In this paper we prove threshold saturation for spatially coupled turbo codes (SC-TCs) and braided convolutional codes (BCCs) over the binary erasure channel. We introduce a compact graph representation for the ensembles of SC-TC and BCC codes which simplifies their description and the analysis of the message passing decoding. We demonstrate that by few assumptions in the ensembles of these codes,
