In order to grow, the founder must go. This is the conventional wisdom which states that when entrepreneurial firms enter a stage of rapid growth the new business quickly surpasses the skills and capacity of the founder. In this phase of rapid growth this paper aims to understand how entrepreneurs perceive their role as founder CEO as their company grows, and what impact this has on their “decisio

Tractography is a visualization technique which reconstructs and models neural fibers in the white matter of the brain based on data from diffusion magnetic resonance imaging. It is already used locally to model parts of dominant fiber pathways but global methods are also emerging which aim to reconstruct all the brain fibers simultaneously. In this thesis we have attempted to improve the current

En wollastonitförekomst vid Stor Hulta gruvor i närheten av Nora har undersökts. I den nedlagda gruvan har tidigare skarnjärnmalm tillhörande leptitformationen brutits. I jämförande syfte har även wollastonit från Akatjvare i Tjåmotisområdet undersökts. Detta är LKAB:s prospekteringsobjekt och är beläget i Jokkmokks kommun. Resultaten för detta material, som utgörs av fyra stuffer av dubbel knytnäThe wollastonite occurrence at Hulta is a skarn deposit associated with iron ore within the Leptite Formation of central Sweden. Wollastonite is found in carbonate layers within the leptite and the rocks have been subject to regional metamorphism. These layers are normally approximately 10 cm thick. Corelogging, microscopic studies and X-ray diffraction show a varied composition of the rock, with

Projects in the space domain are extremely complex and often characterized as being “one-off”, which makes it very difficult to make good predictions on future developments. Furthermore, space projects are also associated with state-of-the-art technology, high costs and long development time. Risks are therefore a threat to project success because they may have negative effects on the project cost

Due to a general shift in manufacturing paradigm from mass production towards mass customization, reconfigurable automation technologies, such as robots, are required.

We experimentally observe longer than long trajectory influence in high-order harmonic generation (HHG) by varying the peak intensity of the driving laser field either through direct attenuation or by chirping the laser pulse. Using a theoretical Gaussian beam model to simulate spatial interference resulting from quantum path interference, we show that the measured interference patterns cannot be

This paper analyses three governments’ institutional advisory mechanisms designed to shape and support universities and individual researchers’ decisions regarding international academic collaboration. Although ostensibly country-agnostic, increasing geopolitical tensions with China have catalyzed the creation of these new structures. Each mechanism seeks to address the complex trade-offs in inter

We report on the fabrication and characterization of amplitude and phase samples consisting of well defined Au or Al features formed on ultrathin silicon nitride membranes. The samples were manufactured using electron beam lithography, metallization and a lift-off technique, which allow precise lateral control and thickness of the metal features. The fabricated specimens were evaluated by conventi

Background: Motion sickness (MS) is a common complaint during most modes of travel. Several medications can be used to treat MS but are often accompanied by side-effects. Objective: To assess whether performing the Valsalva manoeuvre can influence the subjective feeling of MS in healthy individuals. Methods: We included 16 healthy participants (4 female) that underwent two sessions of MS induction

Lewis' concept of admissibility was introduced as an integral part of his famous Principal Principle; the principle that initial rational/reasonable belief should conform to objective chance unless there is evidence to the contrary. At that time Lewis offered only the rough and ready characterisation that evidence not to the contrary of such dependence is admissible. This, together with some suffi

Apart from providing some new experimental data the paper reviews previous investigations concerning fluctuating lift acting on a stationary circular cylinder in cross-flow. In particular, effects of Reynolds number in the nominal case of an infinitely long and nonconfined cylinder in a smooth oncoming flow are discussed. The Reynolds number range covered is from about Re = 47 to 2 x 10(5), i.e.,

Background: Manic episodes with depressive symptoms represent a severe presentation of bipolar disorder. The effi-cacy of drugs shown useful for pure mania is largely unproven in the subset of patients with depressive symptoms. We reviewed different post-hoc analyses evaluating asenapine's effects in patients experiencing depressive symptoms during manic episodes. Methods: Different post-hoc analy

Abstract Food is frequently packed in a controlled environment of gas, in order to extend shelf life. It is of great importance to be able to monitor the status of the packed food to ensure quality. We demonstrate a technique to monitor the gas inside packages non-intrusively by using a laser spectroscopicmethod in scattering solid materials. The technique named GASMAS (GAs in Scattering Media Abs

Background Stigma affects not only people with mental illnesses, but their families as well. Understanding how stigma affects family members in terms of both their psychological response to the ill person and their contacts with psychiatric services will improve interactions with the family. Aims To investigate factors of psychological significance related to stigma of the relatives. Method In a

Many mammals have specialized nose-tips with glabrous and often wet skin, called rhinaria. The function of the rhinarium is unknown in most species. Rhinaria differ not only in shape and skin structure, but also in skin temperature. They are considerably colder in carnivorans than in herbivorous artio- and perissodactyls. Domestic dogs are carnivorans and their noses often feel cold, such that the
