Previous results have shown that severe, prolonged hypoglycemia leads to neuronal cell damage in, among other structures, the cerebral cortex and the hippocampus but not the cerebellum. In order to study whether or not this sparing of cerebellar cells is due to preservation of cerebellar energy stores, hypoglycemia of sufficient severity to abolish spontaneous EEG activity was induced for 30 and 6

The aim of the present study was to test the hypothesis that temporal differences in food chain composition affect lower trophic levels not only directly, by predation and grazing, but also indirectly, by inducing avoidance behavior. In a field study, the recruitment rate from the sediments to water of two algal species (Gonyostomum semen and Peridinium sp.) was higher at low than at high biomass

As part of the Abatement Strategies for Transboundary Air Pollution (ASTA) research program, the dynamic soil chemistry model SAFE was used to make hindcasts and future projections of soil solution chemistry for 645 Swedish forest soils between 1800 and 2100. The data needed were derived from different databases of different spatial resolution ranging from site-specific measurements of soil and st

Popular Abstract in Swedish Vad är egentligen kristen etik? Hur lär människor sig vad som är rätt och fel? Varför förändras normer och värderingar? Sådana stora och viktiga frågor får en konkret belysning i denna avhandling som undersöker normer och värderingar i svensk frikyrklighet. Lite ironiskt sa man förr att frikyrkliga hade en "syndakatalog": de fick exempelvis inte snusa, dansa eller ha sThe dissertation describes and characterises ethical reflection in the Swedish Free Churches during the period from the 1930s to the 1990s. It is built primarily on two sources of material. The first one is a summary of discussions and statements on marriage, divorce and remarriage from books, journals and papers, mainly from two denominations: the Swedish Covenant Church and the Örebromission. Th

To measure the reliability of a website from a user’s point of view, the uncertainty on the usage of the website has to be taken into account. In this paper we investigate the influence of this uncertainty on the reliability estimate for a web server. For this purpose a session based Markov model is used to model the usage extracted from the server’s logfiles. From these logfiles a complete user p

We present a theoretical analysis of surface-enhanced Raman scattering and fluorescence emission from chromophoric molecules located at electromagnetic 'hot spots' in nanoparticle aggregates. The model combines classical electrodynamic enhancement effects with molecular quantum dynamics and allows us to quantify various molecular cross-sections and spectral properties. For a model molecule that si

Maturity-onset diabetes of the young (MODY) is a heterogeneous single gene disorder characterized by non–insulin-dependent diabetes, an early onset and autosomal dominant inheritance. Mutations in six genes have been shown to cause MODY. Approximately 15–20% of families fitting MODY criteria do not have mutations in any of the known genes. These families provide a rich resource for the identificat

The electrocatalytic properties for NADH oxidation of five organic dyes, two indophenol derivatives (2,6-dichlorophenolindophenol and indophenol) and three o-quinone derivatives (phenanthrenequinone, pyrroloquinoline-quinone, and 1,2-naphthoquinone) were compared when adsorbed on zirconium phosphate entrapped in carbon paste. The electrochemical behavior of the immobilized dyes was investigated wi

Studies were conducted to elucidate co-receptor spectrum and function of the inflammatory receptor, CMKLR1/ChemR23, which was recently identified as the receptor for the cystatin-like chemoattractant, TIG2, also named chemerin. An infection model was applied based on stably transfiected NP-2.CD4 host cells expressing various co-receptor constructs and exposed to panels of HIV-1, HIV-2 and SIV prim

Adenocarcinomas of the kidney are rare childhood tumors. Only 30 cases with chromosomal abnormalities have been reported, and neither their karyotypic characteristics nor the molecular mechanisms behind their pathogenesis are clear, except for a special group of papillary tumors characterized by X-chromosome abnormalities. We have cytogenetically analyzed short-term cultured cells from two pediatr

Wider use of oral anticoagulants has led to an increasing frequency of warfarin-related intracerebral hemorrhage (ICH). The high early mortality of approximately 50% has remained stable in recent decades. In contrast to spontaneous ICH, the duration of bleeding is, 12 to 24 hours in many patients, offering a longer opportunity for Intervention. Treatment varies widely, and optimal therapy has yet

Nowadays the power supplying systems have a fundamental importance for all small and portable devices. For low power applications, there are two main ways for producing power: electrochemical batteries and mini engines. Even though in recent years many developments have been carried out in improving the design of batteries, the energy density of 1MJ/kg seems to be an asymptotic value. If the energ

The influence of temperature (20-50 degrees C) and NaCl on mass transfer of pure water and glucose solution (0.0055 M) using an Alfa Laval NFT-50 nanotiltration membrane has been investigated. Addition of 0.017 M NaCl(aq) increased the membrane permeability in comparison to measurements with pure water. Performing cyclic temperature variations using a membrane pre-treated with 0.20 M NaC](aq) caus
