European policymakers are increasingly interested in encouraging and supporting social entrepreneurship. Addressing the goal, this thesis analyses the relationship between human capital and an individual’s propensity for social entrepreneurship in European countries. Additionally, it is investigated how institutional environment moderates this relationship. Utilising a dataset of the Global Entrep
Introduction: Validation of a new test method to determine nicotine from chewing gum extracts with ultra high-performance liquid chromatography. Background: In Quality Control-laboratories, the methods that are regularly used are consistently developed in order to conduct effective analysis procedures. The aim of all of these developments is to simplify the analysis as much as possible and make t
Thermal comfort is a topic that for the last century has interested designers and researchers. European and International standards have given guidelines for assessment of thermal comfort in typical indoor environments for long occupancy, however the transitory spaces and semi-external spaces have not been addressed. Available literature was reviewed and summarize to find appropriate methods for a
Trä och andra organiska material riskerar att angripas av mikrobiell påväxt under vissa temperatur- och fuktförhållanden. Mögel- och rötsvamp kan börja växa på trä om fukthalten är tillräckligt hög. Rötsvampar bryter ner träets olika beståndsdelar i olika utsträckning beroende på svamp- och trädart. Det som påverkar rötsvampars tillväxt är bland annat fukthalt, temperatur, pH-värde och syrehalt. E
The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal. The images arising from the CZT camera have a difference in appearance compared to the images produced by
This thesis explores the under-recognised yet symptomatic visual motif of two women, a recurring theme within a vast array of pictorial examples. Its primary objective is to construct a theoretical and methodological framework capable of comprehending the multiplicity of images in the form of an image collection: The Atlas of Two Women. This inquiry primarily draws on Walter Benjamin’s concept of
The groundbreaking field of synthetic biology has immense potential to revolutionize our society by reducing our reliance on petroleum. With a growing demand for sustainable ingredients and molecules, companies like Amyris, who have successfully developed and commercialized this technology, are poised to reap significant rewards. I am privileged to work for a scientifically advanced organization t
The distribution of 50 species in the south Swedish provinces of Skane (Scania). Halland, Blekinge, Oland and Smaland has been mapped. Many of the species are endemic to southern Scandinavia and some are local endemics within the investigated area. However, there are also several species with a wider North European distribution. Within the area, the number of species shows a regular decline from t
To increase the overall ethanol yield from softwood, the steam pretreatment stage can be carried out in two steps. The two-step pretreatment process was evaluated from a techno-economic standpoint and compared with the one-step pretreatment process. The production plants considered were designed to utilize spruce as raw material and have a capacity of 200 000 tons/year. The two-step process result
Different functions for the programming of the cross flow in asymmetrical flow field-flow fractionation were studied with the aim to find the flow conditions most suitable for the molar mass distribution analysis of high molecular weight polysaccharides. A mixture of four differently sized pullulans covering the molar mass range 5.8 x 10(3)-1.6 x 106 g mol(-1) were used as a model sample. Two type
This paper reports on a parallel implementation of a general 3D multi-block CFD code. The parallelization is achieved by using three strategies. Firstly, it is done on dual-processor PC-clusters where Windows NT systems are running. A multi-thread programming model is adopted for the multi-block code, where one thread corresponds to a block. Shared-memory is used for the exchange of inner-boundari
Analysis of small-scale movement patterns of animals we may help to understand and predict movement at a larger scale, such as dispersal, which is a key parameter in spatial population dynamics. We have chosen to study the movement of a soil-dwelling Collembola, Protaphorura armata, in an experimental system consisting of a clay surface with or without physical obstacles. A combination of video re
One way to extend the lean-burn limit of a natural gas engine is by addition of hydrogen to the primary fuel. This paper presents measurements made on a one-cylinder, 1.6- liter natural gas engine. Two combustion chambers, one slow and one fast burning, were tested with various amounts of hydrogen (0, 5, 10 and 15%-vol) added to natural gas. Three operating points were investigated for each combus
This study considers astrophysics, stellar and nebular astronomy in Sweden. Emphasis is on the role of scientific technologies and practice, and the emergence of a modern observational astronomy, supplanting classical astronomy as the most vital field of Swedish astronomy. The introduction of photography and spectroscopy is discussed, mainly focused on Nils Dunér. The mechanical nature of the pho
We have designed and synthesized a new series of azapeptides which act as potential inhibitors of cathepsin B and/or cathepsin K. Their structures are based upon the inhibitory sites of natural cysteine protease inhibitors, cystatins. For the synthesized azapeptides, the equilibrium constants for dissociation of inhibitor-enzyme complex, K-i, were determined. Comparison of these values indicated t
High-resolution spectra of the chemically peculiar HgMn stars chi Lupiand HR 7775, obtained with the Hubble Space Telescope/Goddard HighResolution Spectrograph, are investigated for their abundance of bismuthby comparison with LTE synthetic spectrum modeling. HR 7775, previouslyknown from International Ultraviolet Explorer spectra to display stronglines of Bi II, is determined to have bismuth pres
