Mer än 10% av Sveriges befolkning lider av någon fobi och detta projekt studerar möjligheten att lindra akrofobi (höjdskräck) med hjälp av virtual reality (VR). Arbetets syfte är därför att undersöka hur man på bästa sätt kan lindra akrofobi med hjälp av VR. Frågeställningarna som skulle besvaras var: ”Kan man med hjälp av enbart visuell och auditiv feedback skapa en trovärdig miljö för att lindraMore than 10% of Sweden's population suffers from some kind of phobia and this project is studying ways to ease acrophobia (fear of heights) with virtual reality (VR). Therefore, the purpose of the work was to investigate how to best ease acrophobia with help of VR. The research questions to be answered were: "Is it possible with just visual and auditory feedback to create a credible envi

The present study aims to contribute to the research on stakeholders’ perceptions of brands that take a stand on social issues and by doing so, express their social brand purpose. Social brand purpose is at the core of a brand, and it reflects the brand’s ideal as well as intent to make people’s lives better. To explore how stakeholders perceive stances on social issues that are taken by purpose-d

This study examines how grandiose narcissism affects the resource acquisition of aspiring entrepreneurs. The study's results help bridge a gap in the literature and provide a better understanding of the nexus between narcissism and entrepreneurial finance. By drawing on previous literature from both fields, we set out to explore the relationship between narcissism and an individual’s preferenc

PURPOSE: The local immune infiltrate's influence on tumor progression may be closely linked to tumor-intrinsic factors. The study aimed to investigate whether integrating immunologic and tumor-intrinsic factors can identify patients from a low-risk cohort who may be candidates for radiotherapy (RT) de-escalation.EXPERIMENTAL DESIGN: The SweBCG91RT trial included 1,178 patients with stage I to IIA

Objective To evaluate whether N-acetyleysteine (NAC) infusion during the first week of life reduces the risk of death or bronchopulmonary dysplasia (BPD in infants with extremely low birth weight. Study design In a Nordic multicenter, double-blind trial, infants (n = 391) weighing 500 to 999 g and on ventilator or nasal continuous positive airway pressure were randomized before the age of 36 hours

Although randomized controlled trials (RCT) are the gold standard for establishing causation in clinical research, their aggregated results can be misleading when applied to individual patients. A treatment may be beneficial in some patients, but its harms may outweigh benefits in others. While conventional one-variable-at-a-time subgroup analyses have well-known limitations, multivariable risk-ba

Purpose – The aim is to understand customers' willingness, or unwillingness, to pay a price premium in the market for consumer packaged food and what kind of images brands can use in order to achieve a price premium. Design/methodology/approach – The study is based on a quantitative survey of brand images found in food and branding literature and their impact on loyalty as well as customers' will

Structural biology has transformed a number of fields of biochemistry and biology. A few examples are the following. The allosteric uptake and release of oxygen from haemoglobin obtained an elegant description from the work of Perutz [ Perutz ( 1970), Nature ( London), 227, 726 - 739; Perutz et al. ( 1998), Annu. Rev. Biophys. Biomol. Struct. 27, 1 - 34]. The structure of tRNA highlighted the fact

Objective-Recent studies failed to show long-term benefit with low-molecular weight heparins (LMWH) in unstable coronary heart disease. A previous study of vascular effects of the cytostatic agent 5-fluorouracil (5-FU) showed that dalteparin prevented thrombosis induced by 5-FU but endothelial damage was not ameliorated and was present also in animals treated with dalteparin only. This study inves

Popular Abstract in Swedish Denna avhandling handlar om utveckling och tillämpning av metoder för jonstråleanalys av lätta ämnen (lättare än ungefär aluminium), framförallt vid en nukleär mikrosond. Vid en nukleär mikrosond accelereras tunga partiklar, t.ex. protoner, av en partikelaccelerator och fokuseras av ett speciellt magnetiskt linssystem ned till en storlek av ungefär 1 mikrometer. Denna sThis thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods. Several signals are acquired simultaneously, and the d

The Nordic Grid facility (NorduGrid [1]) came into operation during summer 2002 when the Scandinavian ATLAS HEP group started to use the Grid for the ATLAS Data Challenges (DC) and was thus the first Grid ever contributing to an ATLAS production. Since then, the Grid facility has been in continuous 24/7 operation. NorduGrid is being used by a growing set of active users from various scientific are

This paper argues that different political structures use different conflict management mechanisms to manage opposition to large hydro projects. Conflicts over the Pak Mun Dam, Thailand (a liberal democracy), and the Bakun Dam, Malaysia (a semi-authoritarian state), are the cases selected for comparison. The export oriented, fast industrialization process brought rapid development in these two cou

European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation.The scope of this thesis is to explore other ways of reducing NOx emissions emittedby a heavy-duty engine. Several technology options are

Abstract: Our aim is to study trends in mental ill-health and socioeconomic-related mental health inequalities over time in Sweden. We also make a first attempt at disentangling why we see such a development, by decomposing any changes in terms of changes in selected demographic and socioeconomic characteristics among the population.

From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur

This article presents the results of a study where the effect of five window glazing types on daylight quality was investigated using a scale model (1:6) of a room with a single, south east-oriented window exposed to the natural sky. The space studied simulated a typical, fully furnished living room. A total of 30 research subjects took part in the experiment, observed the room and filled question

Silicon photomultipliers (SiPMs) are an enabling solid-state technology for low light sensing, with single photon sensitivity and photon number resolving capability. They feature an extremely high internal gain at the 106 level, comparable to photomultiplier tubes (PMTs), with the advantage of low operating voltage (~50 V compared to ~1000 V for PMT) and low energy consumption. The solid-state tec

We present a minimal solver for a special kind of homography arising in applications with planar camera motion (e.g. mobile robotics applications). Since the camera motion we consider only has five degrees of freedom, an explicit parametrisation allows us to reduce the required number of point correspondences to 2.5. Using fewer point correspondences is beneficial when used together with RANSAC, b

BACKGROUND: The aim of radiotherapy is to provide a cure and/or symptomatic relief for children with cancer. Treatment is delivered on a daily basis, 5 days per week, over the course of 5 to 35 days. Many parents find that leaving their children alone during treatment and exposing them to radiation is a challenging experience. To gain an understanding of parents' lived experiences, 10 parents were
