The aim of this master thesis was to develop a rotation-based collimation system for large coaxial high-purity germanium detectors for use in intense radiation fields. A collimator was constructedformed as a cylinder surrounding the detector, with a 90° slit opening to the detector. The rotational asymmetry caused by the slit was used to trace the direction of the incident gamma rays as well as re
Nowadays companies need to consider sustainability issues if they wish to operate in harmony with society and the environment and to leverage their resources efficiently in the long run. Sustainability issues often become the drivers for organizational change due to external pressures and demands. As it takes time for sustainability efforts to bear fruit, companies need to remain committed to the
Urbanization is driving cities to grow, often through urban densification. Utilising computer-based simulations executed over 3D representations of the city is imperative in addressing the challenges posed by implementing sustainable urban densifications; like ensuring adequate access to daylight and limiting noise pollution. However, since these simulations are usually resource-intensive, timecon
Young adults experiencing mental health problems are less educated than their peers, putting them in a more vulnerable position for employment and career possibilities. While Supported employment models have been widely implemented, educational supports may be necessary in order to contribute to longer term and sustainable employment. The aim of this study was to describe the state of current rese
An increasing number of companies are now publicly committing to becoming carbon neutral or achieving net-zero emissions. While most organisations will focus on preventative measures to reach their targets, climate compensation will also make up part of a company’s carbon management strategy. Initial reports indicate that corporate investments in forestry-related initiatives have significantly inc
Problem och syfte: Den här uppsatsen skall undersöka några av företeelserna som har betydelse för ett skapande av en europeisk identitet och ett "gemensamt" Europa. Diskussionen om Europa som gemensam institution handlar oftast om ekonomiska svårigheter, sällan diskuteras t.ex. historiska, normativa, och kulturella mellanmänskliga och mellanstatliga dilemman i större sammanhang. Frågan j
Background: Leading the way in developing digital surveillance camera systems Axis Communications has experienced remarkable growth during the last decade and is now considered the industry leader. Maintaining the core value of high quality is challenging with ever-increasing volumes and a high rate of new product introductions. To find and resolve issues with new products, and ensure a smooth tra
A balance between conservation of nature and economic development is becoming harder and harder to achieve. While, biodiversity is blooming under strict protection laws, people are increasingly lacking tools and resources to feed their local economic growth and development. The following thesis aims at investigating the conflict around ski zone Bansko, located in Pirin National Park in Bulgaria. T
This thesis examines the relationship between gender and entrepreneurial intentions through the mediating effect of neurodevelopmental symptoms frequently associated with Attention-Deficit/Hyperactivity Disorder (ADHD), aiming to provide an additional explanation for the prevalent gender disparity in the entrepreneurial domain. Our study addresses a prominent gap in existing literature by integrat
Current Tanzanian land law offers registration of private interests in land in the form of Certificates of Customary Rights of Occupancy (CCROs) within a broader community lands approach. We conducted qualitative research on the issuance of CCROs along a mountain slope transect in Meru district in northeast Tanzania. This area features intensified smallholder agriculture that evolutionary theory s
Mortality caused by non-communicable diseases has been extremely high in Hungary, which can largely be attributed to not performed preventive examinations (PEs) at the level of primary health care (PHC). Both structures and financial incentives are lacking, which could support the provision of legally defined PEs. A Model Programme was launched in Hungary in 2012 to adapt the recommendations for P
There is a growing body of evidence suggesting that individuals with obsessive-compulsive disorder (OCD) may be sub-typed along different symptom dimensions. These dimensions may help explain responsiveness to current treatments. The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a validated instrument involving a self-report screening tool followed by a structured interview in whi
Background: The Mendelian Society of Lund launched Hereditas in 1920. The purpose of this article is to give an overview of Hereditas’s hundred-year existence, focusing on the conditions for a learned society to publish a scientific journal, and the journal’s importance for the publication and dissemination of genetic research. The article focuses on the historical development of the journal and a
Objectives: The aim of this study was to analyze the effect of longstanding nicotine exposure on bone healing and osseointegration of titanium implants. Materials and Methods: 20 female rabbits received either nicotine (n = 10) or saline (n = 10) administered subcutaneously via mini-osmotic pumps for 32 weeks. The pump delivered 6 mu g/kg/min of nicotine for the animals in the test group. Blood sa
Mainstream research on reading and writing is based on the assumption, common in modern linguistics, that spoken language is primary to written language in most important respects. Unfortunately, the conceptual framework for the study of language and 'literacy' (encompassing both reading and writing skills) is built around this assumption. This is problematic with regard to the philosophy of scien
Popular Abstract in Swedish Laddade partiklar är kända för att sända ut ljus när de rör sig i en krökt bana. Detta ljus kallas synkrotronljus och upptäcktes i mitten av 1900-talet. Sedan dess har det använts i forskning inom kemi, biologi, medicin och materialvetenskap. Utveckling av speciella maskiner för att producera synkrotronljus blev nödvändig för att fortsätta att tillgodose behoven inom deTo ensure the beam with an ultralow emittance and high current the possible effects deteriorating the beam stability must be investigated. When ultrarelativistic particles travel in the vacuum chamber they induce electromagnetic fields which can act back on them and the following particles. The interaction of the beam with the surrounding environment can be described by wakefields in time domain a
Popular Abstract in Swedish De personer som ingår i undersökningen har gemensamt att de har erfarenheter av flera års avancerat narkotikamissbruk, varit drogfria i minst två år samt att de idag är socialt integrerade. Det faktum att de lyckats sluta missbruka narkotika och idag lever "vanliga liv" innebär att de tillhör en grupp som hitintills fått mycket liten uppmärksamhet av missbruksforskningeAim of the study, background, theory and method The two aims of this study are to describe and analyse: i) how drug abusers have transformed their lives from the time when they did not use drugs, to becoming drug abusers, and finally leaving drugs behind them; and ii) what it means to be socially integrated with one's experience of having been a drug abuser. The women and men who participated in
Two methods for visual evaluation of image quality of clinical radiographs have been compared. In visual grading analysis (VGA) specified anatomical structures in an image are visually compared with the same structures in a reference image, and in a free-response forced error (FFE) experiment - an extension of conventional ROC (receiver operating characteristics) analysis - the objective is to cor
