In 2021, combined heat and power plants accounted for 9 % of the electricity production in Sweden. However, Swedish combined heat and power plants plan their production based on the demands of the district heating network. In instances of unforeseen disruptions affecting production, priority is given to meeting heating demand. Consequently, electricity generation and the management of imbalances t
Aid volatility is one of the main topics in the discussion of aid effectiveness in developing countries. The energy sector is relevant for the achievement of sustainable development because this sector holds strong linkages to diverse SDGs. Unlike previous studies that claim the energy sector exhibits higher aid volatility in developing countries compared to developed countries. This thesis aims t
Campylobacter jejuni causes around 100 million cases of gastroenteritis each year and are often transmitted to humans through the consumption of contaminated food, especially poultry. One of the natural enemies of C. jejuni is the bacteriophage Fletchervirus. In this master thesis I have been working on developing and evaluating different tools to modify Fletchervirus which could in the future hel
This thesis explores the impact of community and individual shocks on children’s time use and aims to determine if and under what conditions households use child labor as a response to shocks. For this purpose, four survey rounds of a panel of Ethiopian children aged 5 to 15 are analysed. To address endogeneity problems and to overcome issues related to the data acquisition process, both a fixed e
Bakgrund: Kabinpersonalen präglas av en mängd olika normer och regler, dessa utgörs av säkerhetskrav, hierarkier och professionella riktlinjer. Dessa strukturer styr kabinpersonalens arbete, vars huvudsakliga uppgift är att säkerställa passagerarnas säkerhet och komfort under flygningen. Denna yrkesgrupp står inför en unik utmaning med konstant exponering för passagerare och behovet av att hantera
This thesis investigates the restitution of cultural artefacts looted during the colonial-era, through the comparison between two United Nations Educational, Scientific and Cultural Organization (UNESCO) Conventions and the newly proposed French guideline, Shared Heritage: Universality, Restitution and Circulation of Works of Art (SHURCWA). Through a qualitative case study employing Carol Bacchi’s
As a social change, the sudden collapse of communism1 should well be remembered as one of the most formative events of the 20th century. As a political transformation, it caused an initial rush of euphoria within the 'victorious' West and a wave of hope followed by disillusionment for hundreds of millions in the newly ‘democratic’ sphere. As an economic transformation, its effects were even more t
The construction of multifunctional buildings has increased over the last years as well as the threat level considering antagonistic events. This presents challenges for the fire safety in these types of buildings since the protection objectives needs to be more focused on the functions the buildings are providing. Further the antagonistic exposures might present more challenging fire scenarios. A
A multi-step route to unsymmetrically substituted benzophenones based on cationic hapto6-arene-hapto5-cyclopentadienyl iron complexes has been developed. The key features are nucleophilic aromatic substitution reactions performed on hapto6-2-chlorocarbomethoxybenzene-hapto5-cyclopentadienyl iron hexafluorophosphate with phenoxides, followed by intramolecular Friedel-Crafts ring-closure. The thus f
Ectomycorrhizal fungi form symbiotic associations with tree roots and assist in nutrient-uptake and -cycling in forest ecosystems, thereby constituting a most significant part of the microbial community. The aims of the studies described in this thesis were to evaluate the potential of DNA-based molecular methods in below-ground ectomycorrhizal community studies and to investigate changes in ectom
Heterogeneity in patient populations is an important issue in health economic evaluations, as the cost-effectiveness of an intervention can vary between patient subgroups, and an intervention which is not cost-effective in the overall population may be cost-effective in particular subgroups. Identifying such subgroups is of interest in the allocation of healthcare resources. Our aim was to develop
In this study, a coupled multi-species transport and chemical equilibrium model has been established. The model is capable of predicting time dependent variation of pore solution and solid-phase composition in concrete. Multi-species transport approaches, based on the Poisson–Nernst–Planck (PNP) theory alone, not involving chemical processes, have no real practical interest since the chemical acti
Background: Although clinical studies have shown efficacy of biological agents in moderate to severe psoriasis, observational studies of real-world effectiveness are rare. Objective: To analyse the psoriasis area and severity index (PASI) and quality of life by the EQ-5D questionnaire and dermatology quality of life index (DLQI) in psoriasis patients who switched from conventional systemic treatme
Further characterization of the post-cardiac arrest syndrome (PCAS) is essential to better understand the mechanisms resulting in injury and death. We investigated serial serum concentrations of the stress hormone c-terminal provasopressin (CT-proAVP or copeptin), the cardiac biomarker MR-proANP and a biomarker of oxidation injury, Peroxiredoxin 4 (Prx4) in patients treated with mild hypothermia (
This paper discusses the effects of vegetation cover and soil parameters on the climate change projections of a regional climate model over the Arctic domain. Different setups of the land surface model of the regional climate model HIRHAM were realized to analyze differences in the atmospheric circulation caused by (1) the incorporation of freezing/thawing of soil moisture, (2) the consideration o
In this population-based study the colic incidence was 9.4%, according to telephone interviews with the parents made when the infants were 5 weeks of age (n = 1628), and parental concern about infant crying was common. However, 7-day diaries of colicky and control infants (n = 116 + 119) revealed low distress amounts in colicky infants in general. In the subgroup of Wessel-colicky infants (n = 37)
P2Y(2) receptors, which mediate contractile and mitogenic effects of extracellular nucleotides in vascular smooth muscle cells (VSMCs), are upregulated in the synthetic phenotype of VSMCs and in the neointima after balloon angioplasty, suggesting a role in the development of atherosclerosis. Because released cytokines in atherosclerotic lesions mediate multiple effects on gene transcription in VSM
