In recent years, small businesses have received much attention from policy makers and researchers, in that these businesses are considered important for economic growth and job creation. At the same time small businesses are assumed to face major problems in securing long-term external finance, which is regarded as restraining their development and growth. Small business managers are assumed to us

This paper describes a new method of finding thin, elongated structures in images and volumes. We use shortest paths to minimize very general functionals of higher-order curve properties, such as curvature and torsion. Our method uses line graphs to find the optimal path on a given discretization, often in the order of seconds on a single computer. The curves are then refined using local optimizat

Popular Abstract in Swedish Vid en knäprotesoperation ersätts ledytorna i knäet med en protes gjord av metall och plast. Den vanligaste orsaken till denna operation är artros(ledsvikt. Antalet knäprotesoperationer ökar stadigt och 2009 utfördes 12,700 förstagångsoperationer i Sverige. Resultaten är överlag goda men en allvarlig komplikation som drabbar mellan 1 och 2% av patienterna är bakterieinfThe Swedish Knee Arthroplasty Register (SKAR) was used to identify 478 cases that underwent a first-time revision with exchange or removal of the prosthesis due to infection during the years 1986–2000. 30% of the infections were diagnosed within 3 months from primary operation and two-thirds were diagnosed within 2 years. These cases frequently had a history of wound complication after the primar

The unfolding behavior of ubiquitin under the influence of a stretching force recently was investigated experimentally by single-molecule constant-force methods. Many observed unfolding traces had a simple two-state character, whereas others showed clear evidence of intermediate states. Here, we use Monte Carlo simulations to investigate the force-induced unfolding of ubiquitin at the atomic level

So-called child neuropsychiatric disorders (ADHD/DAMP, autism spectrum disorders, Tourette's syndrome) are being recognized with increasing frequency in child and adolescent psychiatry. Through follow-up studies, case reports and autobiographical accounts it has become evident that these disorders often persist into adulthood, and the need for diagnostic evaluation of adults is increasing. The Neu

Consider a stationary normal process ξ(t) with mean zero and the covariance function r(t). Properties of the sample functions in the neighborhood of zeros, upcrossings of very high levels, etc. have been studied by, among others, Kac and Slepian, 1959 [4] and Slepian, 1962 [11]. In this paper we shall study the sample functions near local maxima of height u, especially as u → -∞, and mainly use si

At national policy level in Sweden, the importance of development of wind power is emphasized. However, the actual implementation is highly dependent on local permit giving for windmills. The legislation governing the permit giving has been revised in an attempt to make the local processes faster and to shift the permit process towards a more regional environmental process as opposed to a more pla

A new efficient synthesis method of angular selective surfaces (ASSs) based on the accurate equivalent circuit model is proposed. The angular dispersion of different components under oblique incidence is modeled by virtual lumped elements in the angular domain. The processes of obtaining the equivalent circuit for substrates, electrically small grids and patch arrays are presented in detail. The s

Background: Irritable bowel syndrome (IBS) is a common disease with unknown etiology. Poor dietary intake with nutritional deficiency and overweight have been described to increase the risk of IBS. The aim of the present study was to compare weight and circulating levels of micronutrients in IBS compared with healthy controls. Design: Cross-sectional study. Methods: Patients diagnosed with IBS and

High-density lipoproteins (HDLs) are responsible for removing cholesterol from arterial walls, through a process known as reverse cholesterol transport. The main protein in HDL, apolipoprotein A-I (ApoA-I), is essential to this process, and changes in its sequence significantly alter HDL structure and functions. ApoA-I amyloidogenic variants, associated with a particular hereditary degenerative di

This thesis investigates the possibility of the mediated city providing a space for resistance in everyday life in a society where free speech channels are strictly controlled. The case studied in this thesis is the phenomenon of a group of fans of a singer who has been banned by the government in mainland China writing graffiti in public urban space on Rehe Road in Nanjing to express their love a

Title: Critical Supply Chain Factors for Scaling a Startup -- A Case Study in the Industry of Semiconductors Author: Pontus Landgren Supervisors: Bertil Nilsson, Lund University, Faculty of Engineering & Lennart Moberg, Acconeer AB Background: A well implemented supply chain strategy aligned with the company's overall strategy is a prerequisite in order to successfully scale a startup.

Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. The major challenge is the understanding of radiometric distortions, which is particularly important while comparing data over different lighting conditions. The study developed and as

Då HovR över Skåne och Blekinge, mål nr. B 2802-10, avkunnade sin dom den 21 september 2011 hade ytterligare en frikännande misshandelsdom behandlats av det svenska rättssystemet. Den tilltalade hade piskat målsäganden med olika redskap så att skador uppkommit. Det som skiljde detta mål från ett vanligt misshandelsmål, var att målsäganden hade samtyckt till de olika handlingarna, som en del av ettAs the Court of Appeals for Skåne and Blekinge, case no. B 2802-10, gave its judgment on September 21, 2011, was yet another acquittal assault judgment processed by the Swedish judicial system. The accused had hit the victim with different instruments in a way that caused damage to the plaintiff. However, what distinguishes this case from an ordinary assaultcase was that the plaintiff had consente
