Compact SPECT systems with cadmium zinc telluride (CZT) solid-state detectors with improved energy resolution and shorter acquisition times have recently been introduced. These systems have, however, different energy characteristics compared to NaI(Tl) crystal-based cameras; therefore, a need exists to develop new simulation models for these cameras. We modeled the charge transport within the CZT
In marine insurance causation is a fundamental principle. Causation defines if a loss falls under the insurance policy or if the loss is too remote to be considered under the insurance policy. In order to define the necessary causal connection different principles are used in different countries, or in relation to different perils. In England the proximate cause principle is used while the Nordic
Presently the telecom industry is going through a massive shift in technology. In the business to business environment regarding delivery and service of fixed telephony, the traditional circuit-switched PBX (private branch exchange) technology is successively replaced by a new Ip-based (Internet protocol) PBX technology. The new way of switching voice-calls doesn't demand a separate infrastruc
The thesis idea originated from that the authors experienced that they would have liked to have more opportunities to apply their educational and personal skills before attending the business world. The authors found a way to accomplish this by the application of a multidiscipline case simulation. The purpose of this master’s thesis is to test an idea and the application of the same. Another purpo
Technical assistance to public sector organisations is a much-debated topic and showcases a considerable size in contemporary international development assistance. Yet, the empirical evidence base on which factors contribute to the outcomes of projects within this field is surprisingly slim and diffuse. Particularly, the mechanisms through which different factors affect project outcomes remains un
Principen att förorenaren betalar är en central miljörättslig princip som innebär att den som orsakat en förorening eller miljöskada ska vara ekonomiskt ansvarig för att denna återställs eller saneras. Principen är emellertid svår att tillämpa i praktiken. Den största svårigheten vid tillämpningen har varit hur ”förorenaren” och ” förorening” ska identifieras och definieras eftersom gemenskapslagsThe polluter-pays principle is an environmental legal principle of utmost importance. It means that the person responsible for environmental damage or pollution should be the one financially responsible for restoring it. The principle is however, difficult to carry out in practice. The biggest difficulty has been to identify and define the “polluter” and the “pollution”. One of the reasons for thi
Populärvetenskaplig sammanfattning: Naturbetesmarkerna minskade med 86,7% från 1927 till 1990. Denna minskning är alarmerande eftersom många idag hotade och sällsynta arter är beroende av dessa. En stor del av anledningen till detta är att staten ända in på 1980-talet i sin rådgivning danade för att dessa marker antingen skulle bearbetas med konstgödsel och ogräsbekämpning eller planteras med trädThe rural landscape of Sweden has changed rapidly during the 20:th century. Measurements from 1927 compared to those from 1990 show that the area of non managed pasture in Sweden has declined by 86.7 %. Since a lot of threatened and rare species are dependent of this kind of land, these figures are alarming. During the last 30-40 years non managed pasture has declined due to abandonment, tree plan
Till följd av en allt strängare lagstiftning kring marknadsföring av tobaksfria nikotinprodukter i Sverige har varumärket Loop utvecklat nya strategier för att synas i sociala medier utan att bryta mot rådande regler. Denna studie undersöker hur Loop iscensätter och kommunicerar sin varumärkesidentitet på Instagram genom strategisk kommunikation som undviker direkt produktreklam. Med utgångspunkt In response to increasingly strict regulations surrounding the marketing of tobacco-free nicotine products in Sweden, nicotine pouch brand Loop has adopted new strategies to maintain brand visibility and consumer engagement on social media. This study examines how Loop constructs and communicates its brand identity on Instagram in a legally restricted environment, using strategic communication tha
Second-hand consumption is promoted as a tool for achieving sustainability goals, yet its actual environmental impact remains insufficiently quantified. This thesis examines the potential of second-hand shops to contribute to carbon reduction, focusing on carla, a Vienna-based second-hand initiative. While second-hand goods are generally assumed to reduce the demand for new products, this benefit
This study explores the renewable energy cooperation between China and the Gulf countries, particularly Saudi Arabia and the United Arab Emirates, focusing on how this collaboration addresses underlying structural asymmetries. These asymmetries include China's technological advancements, institutional frameworks, and discursive power, as well as the Gulf's resource and capital endowments.
Sammanfattning Den 1 juli 2013 trädde den nya statsstödslagen i kraft. Den statliga utredning som dessförinnan tillsattes fick bland annat i uppdrag att analysera om det behövdes särskilda bestämmelser för att tredje part inför svensk domstol ska kunna yrka återkrav eller skadestånd under åberopande av genomförandeförbudet i artikel 108.3 FEUF och att lämna förslag på den författningsreglering soSummary On 1 July 2013 the new state aid act entered into force. The preceding Inquiry had been instructed to consider whether special provisions were needed to enable third parties to bring actions before the Swedish courts with reference to the standstill obligation in Article 108.3 TFEU, and to leave suggestions for any legislation that might be needed in that respect. The Inquiry deemed such
Purpose: To evaluate patients with central retinal vein occlusion (CRVO) and neovascular glaucoma (NVG) using electrophysiology in order to gain better understanding of visual outcome and risk factors, such as previously diagnosed primary open-angle glaucoma (POAG). Methods: Eighty-three patients (83 eyes) initially presenting with CRVO and examined with full-field electroretinography (ERG) within
Popular Abstract in Swedish Vid framställning av koncentrerade fruktjuicer utsätts produkten för värmebehandling i form av indunstning och pastörisering. Värme-behandlingen försämrar produktens sensoriska kvalitet, dels eftersom aromerna är flyktiga och snabbt avdunstar, och dels eftersom värmen påskyndar kemiska förändringar av aromämnena. Några viktiga fördelar uppnås dock genom tillverkning av During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. By recovering the aroma complex from fresh juice and then adding it back to the processed juice, heat treatment can be avoided. Hydrophobic pervaporation is an emerging membr
This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. With acceptable accuracy, the prediction time has been extended up to 5
Taking in to consideration the countless human rights violations and impunity in Africa, there is not a shred of doubt about the dire need for effective human rights protection mechanisms at continental level. This concern has mainly increased due to the Africa Commission’s poor track record of enforcement of human rights norms in the region. Hence, it is in the effort to cure the ills suffered by

The study particularly focuses on workplaces characterized by innovative, aesthetic, and experience-based office solutions. By analyzing the relationship bet
Fastställande av faderskap har historiskt haft stor betydelse i Sverige och varit avgörande för barns rättsliga och sociala ställning. Under lång tid gjordes en tydlig åtskillnad mellan barn födda inom och utom äktenskap, där barn utom äktenskap hade begränsade rättigheter. Sexuella relationer utom äktenskap var länge kriminaliserade och det kvarlevande stigmat kom även att prägla lagstiftningen oThe establishment of paternity has historically been of great significance in Sweden and has been decisive for children’s legal and social status. For a long time, a clear distinction was made between children born within and outside of marriage, where children born outside of marriage had limited rights. Sexual relations outside of marriage were long criminalized, and the lingering stigma also ca
