Bostads- och servicesektorn i Sverige står idag för ungefär 40% av Sveriges totalaårliga energibehov (Energimyndigheten, 2021). Förutom detta används en stormängd energi för nyproduktion, underhåll och rivning av byggnader. Att minskaenergianvändningen i byggsektorns hela livscykel är en nyckel för att nå uppsattaenergi- och klimatmål. I detta projekt analyseras vad som är bäst ur ettenergiperspek
There is a great interest in searching for new environmentally sustainable techniques to enhance the use of agricultural byproducts. In this work, a response surface methodology was used to study the influence of the two independent variables, temperature (25-200 degrees C) and extraction time (3-17 min), in the extraction of antioxidants by pressurized hot water extraction (PHWE) from industrial
The oxygen-evolving complex (OEC) of photosystem II is the only natural system that can form O2 from water and sunlight and it consists of a Mn4Ca cluster. In a series of publications, Siegbahn has developed a model of the OEC with the quantum mechanical (QM) cluster approach that is compatible with available crystal structures, able to form O2 with a reasonable energetic barrier, and has a signif
Anyone trying to maintain a set of text documents in an information retrieval system will run into problems keeping it relevant and up to date as the amount of data increases. This thesis investigates how a collection of documents can be clustered in a way that resembles how a human would organize it. It also assesses how difficult it is to implement this into an existing information retrieval sys
Neurodegenerative diseases such as Parkinson’s can be treated with stem-cell derived specialized neurons. In order to achieve precise directed neural differentiation in vitro we need to understand the gene regulatory mechanisms behind in vivo neural tube patterning. We implement a 3D computational model of brain patterning to simulate this process. The mathematical model is set up by unifying two e
Through the combination of surface sensitive photoelectron spectroscopy and molecular dynamics simulation, the relative surface propensities of guanidinium and ammonium ions in aqueous solution are characterized. The fact that the N Is binding energies differ between these two species was exploited to monitor their relative surface concentration through their respective photoemission intensities.
In this work, we present a parallel approach to complete and restricted active space second-order perturbation theory, (CASPT2/RASPT2). We also make an assessment of the performance characteristics of its particular implementation in the Molcas quantum chemistry programming package. Parallel scaling is limited by memory and I/O bandwidth instead of available cores. Significant time savings for cal
The following dissertation examines the relationship between the actual control of insurgent groups, FARC and AUC, in municipalities of Colombia and the subsequent performance of public services. By resorting to a novel semi-parametric, group-based-trajectory model, this paper manages to discern the de facto presence of such groups at the municipality level, which allows carrying out such examinat
Syfte: Beskriva livet på musikfestivaler och förklara vilken funktion de fyller idag. Frågeställningar: Vilka skäl, förutom musiken, har svenska ungdomar till att delta i en festival? Hur upplever besökarna att deras beteende förändras när de befinner sig på festivalen? Hur kan vi förstå festivalen ur ett större, mänskligt perspektiv? Metod: Jag deltog sommaren 2011 i Peace and Love-festivalen i
We have designed a [Fe(SH)4H]− model with the fifth proton binding either to Fe or S. We show that the energy difference between these two isomers (∆E) is hard to estimate with quantum-mechanical (QM) methods. For example, different density functional theory (DFT) methods give ∆E estimates that vary by almost 140 kJ/mol, mainly depending on the amount of exact Hartree–Fock included (0%–54%). The m
The PAX Good Behavior Game (PAX-GBG) is an evidence-based universal preventive intervention program for classroom use. Our aim was to explore teachers' perceptions of PAX-GBG and their work with it, and whether this changed during the implementation of the intervention. In addition, we explored teachers' perceptions, and changes in perceptions, regarding how they perceived their workload when lear
OBJECTIVE: To establish clear priorities for the care of patients with acquired hemophilia A (AHA) by proposing 10 key principles of practical, holistic AHA management.METHOD: These principles were developed by the Zürich Haemophilia Forum, an expert panel of European hemophilia specialists comprising physicians and nursing and laboratory specialists.RESULTS: The 10 proposed principles for AHA car
The idea of using the thermal mass of a building to maintain a more constant indoor climate is not new. This particular propertyof a building, including its exterior envelope, plays an important part in the reduction of peak power demands, which is becomingan increasingly urgent issue for the heating energy suppliers. The latest smart-grid technology creates new opportunities wherecommunication be
Bio-inspired crossover:Natural genomes are affected by various kinds of mutations, manifesting as variations in the genome. This includes modifications to individual base pairs (single nucleotide polymorphism, SNP), but also short insertions and deletions (indels), and variations in the position (translocations) or multiplicity (copy number variations) of genetic sequences. While SNPs are historic
The direct reprogramming of adult skin fibroblasts to neurons is thought to be controlled by a small set of interacting gene regulators. Here, we investigate how the interaction dynamics between these regulating factors coordinate cellular decision making in direct neuronal reprogramming. We put forward a quantitative model of the governing gene regulatory system, supported by measurements of mRNA
As cell and molecular biology is becoming increasingly quantitative, there is an upsurge of interest in mechanistic modeling at different levels of resolution. Such models mostly concern kinetics and include gene and protein interactions as well as cell population dynamics. The final goal of these models is to provide experimental predictions, which is now taking on. However, even without matured
A variational Bayesian EM with smoothed probabilities algorithm for hidden Markov trees (HMT) is proposed for incomplete tree structured data. The full posterior of the HMT parameters is determined and the underflow problems associated with previous algorithms are eliminated. Example results for the prediction of the types of cells in real stem cell lineage trees are presented.
