Genetic and immunological risk factors of gestational diabetes mellitus

Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som nedsatt glukostolerans av varierande svårighets¬grad som upptäcks under graviditet och som oftast försvinner efter förlossning. GDM innebär ökad risk för såväl moder som barn. Kvinnor med GDM föder ofta stora barn och har ökad risk för komplikationer i samband med förlossningen. GDM-prevalensen varierar avsevärt mellan olika popuGestational diabetes mellitus (GDM) is a heterogeneous disorder that is defined as carbohydrate intolerance with onset or first recognition during pregnancy. Impaired beta-cell function and insulin resistance are the hallmarks of GDM. The overall aim of this thesis was to study the genetic and immunological risk factors that increase susceptibility to GDM. First, we investigated whether autoimmuni

Self-assembly of chiral bicyclic keto-alcohols into supramolecular helices in the solid state

The bicyclic keto-alcohol (1S,4R,6S)-bicyclo[2.2.2]octan-6-ol-2-one, (+)-3, self-assembles in the solid state through hydrogen bonds between the alcohol and the carbonyl groups creating supramolecular helices, without the aid of other forces such as pi-pi interactions to stabilise the superstructure. Furthermore, the bicyclic compound (4) although structurally quite different, in relation to (+)-3

Particle-visualisation - a tool for determination of rise velocities

Particles from post denitrifying Kaldnes Moving Bed(TM) Process were studied using an optical borescope, a visualisation technique that provides opportunities for both qualitative and quantitative studies of the separation mechanism in Dissolved Air Flotation (DAF). Rise rates for particle/bubble aggregates were estimated showing great variability. Two groups of aggregates were distinguished; rela

Experimental demonstration of data erasure for time-domain optical memories

Data erasure is considered an essential requirement for a practical optical time-domain memory, and it requires that the laser used have very good frequency stability. Such a laser is developed for this work, and data erasure is demonstrated with a sample of YSiO5:Eu3+ for write/rewrite pulse sequences of up to a duration of 100 μs. This is two orders of magnitude longer than had been achieved pre

The Power to do Good : Post-Revolution, NGO Society, and the Emergence of NGO-Elites in Contemporary Nicaragua

This thesis critically examines the world of NGOs in contemporary Nicaragua, and suggests connections between the current development 'boom' and the emergence of a materially privileged local development elite, which by means of its cultural and economic capital are in a position to exiercise considerable power in relation to other less powerful strata of the population. It is based on fieldwork c

MIMO Decoding Algorithm and Implementation

Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. The main contributions consist of four algorithms and three VLSI i

Vårdnadstvister : En rättssociologisk studie av tingsrätts funktion vid handläggning av vårdnadskonflikter med utgångspunkt från barnets bästa

Popular Abstract in Swedish I Sverige bryter drygt 30 000 föräldrapar årligen upp från sin relation. Tillsammans har dessa föräldrar cirka 55 000 barn. I samband med föräldrarnas separation skall frågor om de gemensamma barnens vårdnad, boende och umgänge lösas. De flesta föräldrar klarar detta på egen hand eller med stöd av samarbetssamtal eller familjerådgivning, men ungefär 10% av de separerandThe purpose of this socio-legal dissertation is to examine the role of the district court in the handling of custody disputes, from the standpoint of the child's best interest. More specifically, the focus is partly on the relationship between the family and society during district court proceedings, and partly on the relationship between civil law and public law procedure that is to say between t

Thermodynamic and spectroscopic studies of cadmium(II)-N-(phosphonomethyl)glycine (PMG) complexes

Speciation and equilibria in the H+-Cd2+-N-(phosphonomethyl)glycine (PMG, H3L) system have been studied in 0.1 M Na(Cl) medium at 25.0 degreesC. Formation constants for a series of mononuclear complexes, CdHL, CdL-, CdL24- and CdL(OH)(2)- were determined from potentiometric titrations. The structures of the predominating species CdL-, and CdL24- in solution were investigated using EXAFS and IR spe

Deactivation of oxidation and SCR catalysts used in flue gas cleaning by exposure to aerosols of high- and low melting point salts, potassium salts and zinc chloride

For the purpose of this deactivation study, Pt- and vanadia supported catalysts were used. The catalysts have been exposed to aerosol particles of inorganic salts, with high- or low melting points. The average diameter of the generated salt particle was kept constant at around 70 nm. The aerosol particle penetration depth for the samples exposed to potassium salt, was 1 μm as measured by scanning

A comparative study of two methods for determination of pH, exchangeable base cations, and aluminum

The ability to compare soil chemical data achieved by different chemical extraction methods is a necessity for an efficient long-term monitoring of soils and for comparisons of results from regional soil surveys with differing standard methods. This study compares two common, methods for analysis of soil chemical properties, the combination of soil extraction in 1.0 M NH4Cl and 1.0 M KCl and the s
