We introduce a new model to address three methodological biases in research on new venture growth and survival. The model offers entrepreneurship scholars numerous benefits. The biases are identified using a systematic review of 96 papers using longitudinal data published over a period of 20 years. They are: (1) distributional properties of new ventures; (2) selection bias; and (3) causal asymmetr
It was intended with this research to estimate in-sample and out-of-sample Value-at-Risk(VaR) on forwards’ data in Nordic electricity market by using different parametric and nonparametric approaches and investigate which of them give the most accurate results after implementation of back-testing. There were two confidence levels of 95% and 99% used in this research. After implementation of data
Cartilage oligomeric matrix protein was purified in a native form from normal adult human articular cartilage. The key steps in the purification scheme were selective extraction with buffer containing EDTA, wheat germ agglutinin affinity chromatography, and removal of the related protein thrombospondin by heparin affinity chromatography. Particles of cartilage oligomeric matrix protein viewed by e

Popular Abstract in Swedish Denna rapport behandlar trafiklaster på broar och de lasteffekter som de ger upphov till. Böjmoment och tvärkraft för olika brotyper beskrivs i form av statistiska fördelningar med tillhörande parametrar. Dessa är baserade på mätningar av verklig trafik gjorda i Sverige under åren 2002-2003 i Vägverkets regi. Resultaten finns redovisade i Vägverket (2004b), och finns laThis thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. The statistical distributions are based on measurements of real traffic, made in Sweden during 2002-2003. The measurements are managed by the Swedish R
Two years of harmonized aerosol number size distribution data from 24 European field monitoring sites have been analysed. The results give a comprehensive overview of the European near surface aerosol particle number concentrations and number size distributions between 30 and 500 nm of dry particle diameter. Spatial and temporal distribution of aerosols in the particle sizes most important for cli
Abstract Recent financial crises have demonstrated the importance of accurately measuring financial risks in order to be able to employ mitigating risk policies. This essay investigates the question whether a GARCH model augmented by an autoregressive conditional jump intensity component can improve value-at-risk forecasts in comparison to common GARCH models. Therefore, the VaR forecasting perfor
This thesis concerns retrospective and prospective studies of the atrioventricular (AV) conduction properties in patients with cardiac arrhythmias. The objectives of the retrospective studies were to further delineate the sex distribution in patients with Wolff-Parkinson-White syndrome (WPW) and AV nodal reentrant tachycardia (AVNRT) and to determine the underlying mechanisms of the differences in
Handelsbolag och kommanditbolag är juridiska personer men inte skattesubjekt vid inkomstbeskattning. Huvudregeln är att ett sådant bolags resultat beskattas hos dem som är delägare i bolaget vid räkenskapsårets utgång. Den skattemässiga fördelningen ska i princip grundas på bolagsavtalet eller vad som annars har avtalats mellan delägarna. Syftet med förevarande uppsats är att utreda huruvida friTrading partnerships and limited partnerships are legal entities but not a taxable subject for income taxation. The main rule is that the profit of such a company is taxed on those who are partners in the company at the end of the financial year. The tax distribution shall in principle be based on the company agreement or what has otherwise been agreed upon between the partners. The purpose of th
Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. Om kontrollen brister kan utgången försämras i form av tillstånd såsom preeklIn this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery.

Purpose/Background: Ultra-high dose rate radiotherapy (RT) has shown potential for differential normal tissue (NT) sparing (a phenomenon termed the “FLASH effect”), particularly for larger fraction doses (>5 Gy). However, transitioning to hypofractionation may increase late-reacting NT toxicity, counteracting the FLASH effect. This study evaluates whether FLASH-RT can provide netsparing for organs
Background: Neutrophil gelatinase-associated lipocalin (NGAL) has been suggested as the most promising biomarker of acute kidney injury. However, there are no reliable data on analytical sensitivity and reference limits of urinary NGAL (uNGAL) assay in pediatric age. The aim of the present study is to evaluate the analytical sensitivity and the reference range of uNGAL measured in urine specimens
Popular Abstract in Swedish Näthinnan (retina) spelar en central roll för vår förmåga att se. Den sitter längst bak i ögat och precis på samma sätt som objektivet i en kamera fokuserar en bild på filmen, fokuserar ögats "objektiv", dvs. hornhinnan och linsen, en bild på näthinnan. Denna bild, bestående av ljus av olika färg och intensitet, omvandlas av näthinnan till elektriska nervsignaler som skThe main objective of this thesis was to investigate the fate of photoreceptor cells when using different strategies for retinal cell transplantation. Comparing transplantation of fragments of embryonic retina with cell suspensions of the same tissue we found that transplantation of fragments of embryonic retina result in mature transplants with a higher degree of cellular organization than transp
This article describes how a wheel–rail wear detection parameter based on noise was developed by running a rapid transit train instrumented with microphones in a depot with a small curve radius. This full-scale test made use of previous knowledge gained from lab-scale tests. The lab- and full-scale tests showed that noise could be used as an indicator of wear transition, when normal wear turns int
In radiological diagnostics and therapy, it is important that practitioners, referrers, (i.e. radiologists, radiation oncologists and others in health-care) are aware of how much radiation a patient may receive from the various procedures used and associated health risk.

Nociceptive withdrawal reflexes (NWRs) were studied in adult rats in which the movement patterns produced by single muscles had been altered by neonatal tendon transfer. NWRs evoked by cutaneous noxious mechanical and thermal (CO2-laser) stimulation were recorded using electromyography in a decerebrate spinal preparation. The sensitivity distribution within the receptive fields of the NWRs of the
