The aim of the current work was at development and validation of modeling tools for simulation of pulverised wood flames in furnaces and study how different factors influence on such flames. The numerical model involves different sub-models for the physo-chemical processes, such as, two-phase flow motion, drying, devolatilization and shrinkage of particles, the formation and oxidation of volatile,
This thesis deals with the development of new reaction methodology for stereoselective synthesis, as well as total synthesis of natural products and investigations of the stereochemical outcome in the Mukaiyama aldol reaction. Chapter 2 describes efforts made towards the total synthesis of the oxindole natural products perophoramidine and the communesin. The first part of this chapter aims to de
A constitutive model for aluminum alloys under hot working conditions is proposed. The elastic-viscoplastic model is implemented in a finite strain continuum mechanical framework. The model accounts for the interplay between dynamic recovery and recrystallization during hot working of aluminum alloys and central aspects of microstructure evolution such as grain/subgrain size and dislocation densit
Membrane proteins play several important roles in a cell. Among these proteins are aquaporins (AQPs) and transient receptor potential (TRP) ion channels that mediate water transport, temperature and noxious chemical sensation, respectively. The function of some AQPs, for example the spinach isoform SoPIP2;1 is regulated by pH, phosphorylation and heavy metals such as mercury. However, the mechanis
In this paper we study structure from motion problems for parallel cylinders. Using sparse keypoint correspondences is an efficient (and standard) way to solve the structure from motion problem. However, point features are sometimes unavailable and they can be unstable over time and viewing conditions. Instead, we propose a framework based on silhouettes of quadric surfaces, with special emphasis
Objective: Iron isomaltoside (Monofer®) is a high-dose intravenous iron preparation with good tolerability and efficacy in inflammatory bowel disease (IBD) patients with iron deficiency anaemia (IDA). This trial evaluates the safety and efficacy, including effect on intact fibroblast growth factor 23 (iFGF23) of a high single dose and cumulative doses of iron isomaltoside in IBD patients with IDA.
This paper investigates the usability of a cost model to assess sustainable production. The aim is to develop an established cost model to also take sustainability into consideration and hence evaluate sustainable production on the shop floor. To facilitate the analyse literature have been studied to find indicators for sustainable production. The indicators have then been mappedtogether with para
Primary ciliary dyskinesia (PCD) is characterized by dysfunction of respiratory cilia and sperm flagella and random determination of visceral asymmetry. Here, we identify the DRC1 subunit of the nexin-dynein regulatory complex (N-DRC), an axonemal structure critical for the regulation of dynein motors, and show that mutations in the gene encoding DRC1, CCDC164, are involved in PCD pathogenesis. Lo
Background: Identification of disease-associated single nucleotide polymorphisms (SNPs) in seasonal allergic rhinitis (SAR) may be facilitated by focusing on genes in a disease-associated pathway. Objective: To search for SNPs in genes that belong to the T-cell receptor (TCR) pathway and that change in expression in allergen-challenged CD4+ cells from patients with SAR. Methods: CD4+ cells from pa
Could the use of CSA practices stabilize the hunger crisis? Despite the general understanding that CSA practices increase farmers' food security, its resilience to climatic shocks is much less understood. To address this gap, this study analyzes the effect of three CSA practices: inorganic fertilization, intercropping and improved seeding on maize productivity in Ethiopia, Tanzania, and Uganda
The high youth unemployment in Uganda has resulted in youth volunteering to gain competitive advantages in the labour market. Volunteering has an important place in social development, and it is beneficial for the individual. This study investigated how youth volunteering within non-governmental organisations are creating opportunities for youth empowerment in Kampala, Uganda. A majority of previo
Background. This case-control study was performed to evaluate whether adding first-trimester maternal serum testing to nuchal translucency measurement would improve the antenatal detection of Down's syndrome and decrease the number of women offered fetal karyotyping. Methods. In the Swedish Nuchal Translucency Trial 39,572 pregnant women were randomized to a routine scan at 12-14 gestational weeks
The transformational mode of sustainability science is concerned with generating actionable knowledge and practical solutions to complex sustainability challenges in order to facilitate a transition towards sustainability by strategizing transformational pathways. However, some scholars in the field believe that sustainability science lacks such capacity, since so far greater focus has been put on
This paper estimates labor supply effects for informal caregivers in Sweden using four waves of the SHARE data panel. To give daily or weekly care to a parent, step parent or parent in law is found to be more common among women than among men and is associated with lower employment probability for daily caregivers although the causal direction of the relationship is unclear. No negative effect of
