Investigating motivation to create a social enterprise is a continuing concern within entrepreneurship which was expressed in previous studies. Therefore, the purpose of this thesis is to explore the antecedents of social entrepreneurial motivation and the trigger events that motivated the social entrepreneur to start a social enterprise. The life story method guided in the data collection and ana

Recently, Ombashi et al. published a systematic review aiming to identify the pitfalls in the development and implementation as well as factors influencing long-term success of a multidisciplinary, international registry for cleft care on a global scale. The purpose of this letter to the editor is to highlight that the review failed to include the Swedish quality registry for patients born with cl

Metalloenzymes are proteins that contain one or more metal ions bound to protein. They constitute about one-third of all enzymes known so far and they often perform hard chemical reactions involving small substrates, like H2 and N2. In our research, we focus on those metal ions that are located in the active sites and perform redox reactions, i.e. involving electron transfer. Why enzymes?Metalloenzymes catalyse a wide variety of reactions in nature. In the thesis, I have studied the reaction mechanism of three metalloenzymes, viz. [NiFe] hydrogenase (H2ase), dimethyl sulfoxide reductase (DMSOR) and formate dehydrogenase (FDH), by theoretical methods, namely quantum mechanics (QM), combined quantum mechanical and molecular mechanics (QM/MM), as well as QM/MM thermodynamic cycle per

Popular Abstract in English Proteins are a class of biological macromolecules that perform countless fundamental and diverse functions in living organisms. Chemically speaking, they are polymers built out of monomeric units called amino acids. All biological proteins are constructed out of 20 different amino-acid types. To form protein molecules, amino acids are linked together in a linear chain lThe minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. Therefore, to predict the native state of a protein directly from sequence, a computer algorithm must evaluate a large number of possible conformations using accurate sco

How signal diversity evolves under stabilizing selection in a pheromone-based mate recognitionsystem is a conundrum. Female moths produce two major types of sex pheromones, i.e., long-chainacetates, alcohols and aldehydes (Type I) and polyenic hydrocarbons and epoxides (Type II), alongdifferent biosynthetic pathways. Little is known on how male pheromone receptor (PR) genes evolvedto perceive the

This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular info

The number of remote teams has increased in recent years and this upward trend may persist. The growth is partly enabled by advancements in Information and Communication Technolo-gy (ICT) and globalization. Although organizations benefit from certain advantages that re-mote teams introduce, inadequate communication amongst remote team members can lead to project failures. Since technology has an i

Plattektoniska processer formar idag vår jord genom vulkanism, relaterad till divergenta och konvergenta plattrörelser. Hur länge har plattektoniken existerat och hur kan vi spåra plattektoniska processer bakåt i tiden? Detta kandidatarbete behandlar och diskuterar olika typer av plattektoniska indikatorer, hur de går att koppla till moderna processer och hur tillförlitliga de anses vara. Moderna Plate tectonic processes shapes our earth due to volcanism, related to divergent and convergent plate motions. When did plate tectonics begin and how can we trace plate tectonic processes throughout time? This Bachelor thesis address and discuss different plate tectonic indicators and their reliability. Modern analogues are indicators that can be linked to modern plate tectonic processes, and does

The average build year for existing multi-family buildings in Sweden is1959, circa 95 % of building built before 1960 uses natural ventilation and circa 45 % of these have failed the obligatory ventilation control that exists in Sweden. In the EU buildings stand for 30 % of the total energy usage and the aim is to get buildings to a near zero energy building. The aim of this thesis is therefore to

Small ligaments connecting the fracture surfaces just behind a moving crack front are assumed to exist under certain conditions. The ligaments are rapidly torn as the crack advances. Inelastic straining of such ligaments influences the energy balance in the fracture process. The rapid tearing of a single ligament is studied both numerically and experimentally.

Drones have been used by the military since mid-1970 but the development of autonomous systems from the turn of the millennium and onward has opened the area of UAV to civil service and the public immensely. Today UAV technology saves lives in Search And Rescue operations, complements and supports full scale vehicles at the Police force and assists in surveys and documentation of ground and forest
