Inom partikelfysik försöker forskare hitta en så djupgående och allmän modell som möjligt. Den modell som experimentellt har verifierats kallas för Standardmodellen (SM). Det finns dock andra teorier, såsom Tvåhiggsdubbletmodellen (2HDM), som innehåller mer exotisk fysik. Dock är experimentella verktyg begränsade och som fysiker vill man gärna kunna ha en teori för att kunna förutspå egenskaper soIn this thesis, we study the Higgs mass spectrum and spontaneous CP violation, where one of the Higgs vacuum expectation values acquires a non-trivial phase θ in a Type-I 2HDM. We begin by investigating CP violating effects at tree-level, and then expand our studies by taking into account one-loop radiative corrections. After imposing tadpole conditions we discover that this model gives the same m

Den här studien handlar om att öka förståelsen för den interaktion som sker på Instagram. Instagram är en applikation och social plattform där miljontals bilder, videos och texter publiceras varje dag. Det finns en pågående debatt om vad detta får för påverkan, positiv såväl som negativ. Instagrams alla funktioner innebär nya tillvägagångssätt för hur vi människor interagera med andra. För att få

Abstract—For those living today with severely malfunctioning heart valves, replacement is the only available treatment. Patients are today typically offered either mechanical valves, xenograft or allograft. Decellularized heart valves have the potential of becoming one of the standard alternatives for such heart valve transplants. Decellularized heart valves offer a reduced risk of calcification a

Exploring the contributing factors of economic growth is a long-standing research field in economic study. However, natural capital stock has been widely excluded from this investigation. This thesis attempts to include natural capital stock in an augmented Solow growth model utilizing Swedish national accounts from 1850 to 2010. The model found that Swedish natural capital stock played a limited

Introduction Skin metabolomics may serve as a powerful tool to evaluate the physiological changes oc- curring in the body as a range of compounds, coming from inside the body, are retained in the skin. Background The diffusion kinetics of metabolites across the skin, the composition of the skin, the metabolites released as a consequence of different illnesses as well as the relationship be- tween

Deprivations and inequalities caused by poverty have social and economic consequences that prevent the poor from affording the most basic needs and thus, their eradication is crucial for a more equal world. However, existing studies on rural poverty in low-income nations are rare and often focus on the impact of economic indicators. Using the mixed methods of combining quantitative data with docum

Arctic amplification (AA) is defined as the enhanced warming of the surface temperatures in the Arctic region relative to the globe or Northern Hemisphere (NH) in response to external forcings. It is a prominent feature of the climate system. Various metrics have been used in studies to quantify AA, and this introduces a challenge when comparing studies due the differences in AA magnitudes. This s

This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E.ON is to have a more precise way to estimate the energization consequences of increasing the transformer size in the grid, since currently is being used a rule of thumb that relates the trans

Bakgrund: I Sverige erbjuds alla kvinnor mammografiscreening mellan ålder 40–74. Inför mammografiscreening finns ett frågeformulär som kvinnan ska besvara innan undersökningen. Under mammografiundersökningen klär patienten av sig på överkroppen för att underlätta undersökningen och för att minska risker för artefakter i bilden. Syftet med studien var att beskriva kvinnors upplevelser av mammografi

The corporate reporting practice is adapting to rising demands by stakeholders and shareholders for an enhanced consideration of non-financial information. These interest groups demand management to look beyond the financials and determine which factors create long-term value for the organisation. Moreover, regulatory pressure is exercised on the company. The purpose of this thesis is thus, to ga

Domestic violence is a cruel and inhumane act of aggression that is inflicted on a victim by someone in their close domestic circle. This includes partners, ex-partners, immediate family members, other relatives and family friends. Violence within the home is the most common form of interpersonal violence for women. The aim of domestic violence programs and shelters is to empower the survivors an

In this bachelor project, the main objective is to investigate how a two-level quantum system can be controlled using weak continuous measurements and feedback control. The Monte-Carlo method was used to simulate the system dynamics under measurement and feedback to investigate how the system state can be controlled. This thesis concludes on how the feedback function impacts the purity of the stat

Endometriosis is an inflammatory disease where endometrium grows outside the uterus. It affects 10 percent of women, most presenting with symptoms during adolescence. The median age for diagnosis is 37 y/o, despite the early onset. Diagnosing endometriosis is difficult in children, and adolescents with endometriosis is an area in need of research. Previous studies have found that women with endome

Den föredragna metoden för att syntetisera terapeutiska peptider är idag genom fastfas peptidsyntes (SPPS). SPPS är en process som genererar mycket avfall, där huvudkomponenten i avfallet är de toxiska lösningsmedlen N,N-dimetylformamid (DMF), N-metylpyrrolidon (NMP) och diklormetan (DCM).3 Därför är det önskvärt att söka efter nya och grönare lösningsmedel att använda för SPPS, vilket är vad som The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). 3 It is therefore desirable to search for new and greener solvents to use for SPPS, which is what has been studied

The transport sector is responsible for a third of Swedens’ total GHG emissions, where the private cars are a large part of this. Sweden is committed to reducing the emissions from the transport sector with 70 % until the year 2030. Shifting the vehicle fleet to electrical will be one important factor in achieving the goal, but such technical innovation will not be enough. To reach a more sust

Uppsatsen ämnar att fastställa vilken roll och betydelse som tillskrivs revisionsyrket i det brottsförebyggande arbetet och bekämpningen av penningtvätt. Det sekundära syftet för studien utgörs av en utredning för vilka egentliga anledningar och aktörer som orsakar den konflikt som råder kring revisorns faktiska roll i frågan. Studien antar en induktiv forskningsansats med ett kvalitativt angrepps

Could the use of CSA practices stabilize the hunger crisis? Despite the general understanding that CSA practices increase farmers' food security, its resilience to climatic shocks is much less understood. To address this gap, this study analyzes the effect of three CSA practices: inorganic fertilization, intercropping and improved seeding on maize productivity in Ethiopia, Tanzania, and Uganda

Purpose: The purpose of this study is to investigate whether certain CEO- and firm characteristics have an impact on the extent of abnormal return on Swedish firms at the event of a CEO insider trade. Furthermore, the study aims to examine whether there is a difference depending on firm size and sector. Methodology: An event study has been performed based on the market model where the presence of
