Muscular dystrophies involving the dystrophin-glycoprotein complex: an overview of current mouse models

The dystrophin-glycoprotein complex (DGC) is a multisubunit complex that connects the cytoskeleton of a muscle fiber to its surrounding extracellular matrix. Mutations in the DGC disrupt the complex and lead to muscular dystrophy. There are a few naturally occurring animal models of DGC-associated muscular dystrophy (e.g. the dystrophin-deficient mdx mouse, dystrophic golden retriever dog, HFMD ca

Undervisa mot våld. Attityder, läromedel, arbetssätt

Syftena med det i projektet beskrivna inlärnings- experimentet var att studera barns attityder till våld och att med ett attitydtest undersöka effekterna av undervisning mot våld. Samtidigt jämfördes individuellt arbete och grupparbete samt användningen av tre slag av läromedel: texter, bilder och muntliga uppgifter. Både process- och produktvariabler undersöktes. Deltagare var elever i åldrarna 1The main aim of this study has been to influence the attitudes of students, Grades 4-6, in order that they will become opposed to the use of violence. The entire project was conducted during a full academic 20-credit term, as part of inter- mediate level teachers' training. The purpose of this learning experiment was threefold: 1. To study children's attitudes towards violence. 2. To study the eff

Backcross and partial advanced intercross analysis of nonobese diabetic gene-mediated effects on collagen-induced arthritis reveals an interactive effect by two major loci.

Genetic segregation analysis between NOD and C57BL strains have been used to identify loci associated with autoimmune disease. Only two loci (Cia2 and Cia9) had earlier been found to control development of arthritis, whereas none of the previously identified diabetes loci was of significance for arthritis. We have now made a high-powered analysis of a backcross of NOD genes on to the B10.Q strain

Global repolarization sequence of the ventricular endocardium: Monophasic action potential mapping in swine and humans

The aim of this study was to evaluate the global sequence of repolarization over the ventricular endocardium. Disturbances in myocardial repolarization are associated with the genesis of arrhythmias. However, little is known about the global sequence of repolarization. Monophasic action potentials (MAPs) were recorded from 61 +/- 18 LV and/or RV sites in ten healthy pigs and from 43 +/- 15 LV or R

Sensitizing and protective substances in radiation therapy and predictive assays

In an investigation by the Swedish Cancer Society, an expert group described the present status, critical issues and future aspects and potentials for each of nine major areas of radiation therapy research. The present report deals with the use of sensitizing and protective substances in radiation therapy and predictive assays on normal tissues and tumour response.

Evidence of reduced measurement uncertainties from an FTIR instrument intercomparison at Kiruna, Sweden

We report the results of an intercomparison of vertical column amounts of HCl, HF, N(2)O, HNO(3), CH(4), O(3), CO(2) and N(2) derived from the spectra recorded by two ground-based FTIR spectrometers operated side-by-side using the sun as a source. The procedures used to record spectra and derive vertical column amounts followed the format of previous instrument intercomparisons organised by the Ne

Performance modeling and control of web servers

This thesis deals with the task of modeling a web server and designing a mechanism that can prevent the web server from being overloaded. Four papers are presented. The first paper gives an M/G/1/K processor sharing model of a single web server. The model is validated against measurements ands imulations on the commonly usedw eb server Apache. A description is given on how to calculate the necessar

Some aspects of tensile fracture behaviour and structural response of cementitious materials

This report deals with stability and validity analyses of direct tension tests, and an investigation into structural behaviour of various materials in tensile fracture. The influence of rotation in damage zone on the stress-deformation curve is investigated. The role of rotation stiffness of testing set-ups for a stable tension test is analysed. The bump effect, i.e. steep stress drops in stress-d

The thesis’ contribution is studies of this specific institutional development. New Institutional Economic theory is used to scrutinize the driving forces of this development. The thesis consist of three papers. The purpose of the first paper is to discuss and to analyze the

Rare earth elements (REE) and other trace element concentrations in proximal Chicxulub ejecta deposits from northern Belize – support for a single-impact scenario

Four exposures of Chicxulub impact ejecta along the Mexico-Belize border have been sampled and analyzed for major and trace element abundances. The ejecta deposits consist of a lower spheroid bed, containing clay and dolomite spheroids, and an upper diamictite bed with boulders and clasts of limestone and dolomite. The matrix of both beds is composed of clay and micritic dolomite. The rare earth

Comparison of different variable selection methods conducted on NIR transmission measurements on intact tablets

Near infrared (NIR) transmission spectroscopy is a promising method for fast quantitative measurements on pharmaceutical tablets, but there are still some problems to overcome in order to incorporate the technique as a control tool in tablet production. The main problem is the limited precision for multivariate calibrations based on NIR transmission data. The precision is affected by several facto

Particle formation and capture during spray drying of inhalable particles

An investigation of the spray drying process is made in great detail regarding particle formation and capture efficiency with focus on the production of inhalable particles. Mannitol was spray dried as model substance and the spray-dried products were characterized. The resulting products consisted of smooth spheres with a volume median diameter of 2.2-5.5 mum, and narrow size distributions. The i

NMR diffusometry and the short gradient pulse limit approximation

In NMR diffusometry, one often uses the short gradient pulse (SGP) limit approximation in the interpretation of data from systems with restricted diffusion. The SGP limit approximation means that the gradient pulse length, delta, is so short that the spins do not diffuse during the pulse duration, but this condition is rarely met. If the length scale of the pores corresponds to the molecular mean

A memory-efficient optimal APP symbol-elecoding algorithm for linear block codes

We propose a simple modification of the famous Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm for linear block codes. The modified algorithm requires one forward and two backward recursions in the code trellis, but eliminates the need to store the whole trellis. Compared with the BCJR algorithm, the computational complexity is slightly increased, but the storage requirement is reduced.

Measurement of light gradients and spectral regime in plant-tissue with a fiber optic probe

A method is described in which light gradients and spectral regime can be measured within plant tissue using fiber optics. A fiber optic probe was made by modifying a single optical fiber (200 μm diameter) so that it had a light harvesting end that was a truncated tip 20–70 μm in diameter. The probe was a directional sensor with a half-band acceptance angle of 17–20°. Light measurements were made
