The investigation of Bismuth surface structures on InSb(110) surfaces is driven by the need to advance semiconductor technology for enhanced electronic device performance and new applications in optoelectronics and quantum computing. III-V semiconductors offer superior electronic properties compared to silicon. Incorporating Bismuth into these materials can significantly manipulate the bandgap, ma

The brain simulates the world around us using sensory information and provides an estimation of reality in which actions can be executed. This estimation of reality is controlled by attention which decides which information is accepted, further processed and ignored. The process of attending a certain part of the sensory information while ignoring other parts is called selective attention. I have
Blandine Lyonnard How microbes in different soils react to drought and rainfall? Drought periods followed by rainfall events induce large release of CO2 from the soil to the atmosphere. This phenomenon, known as the “Birch effect” can contribute to global warming. With climate change, there will be more and more cycles of drought followed by rainfall events. Therefore, there will be more Birch e
Background Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) have a high risk of developing colorectal cancer and dysplasia. Ursodeoxycholic acid (UDCA) has been suggested to have chemopreventive effects on the development of colorectal cancer and dysplasia but long-term data and larger trials are lacking. Aim To evaluate the effect of high dose (17-23 mg/kg/d
In the last decade, there has been a substantial shift from actively managed funds to funds with passive investment strategies. This shift was also observed by Shleifer (1986), who identified that passive investment funds began to significantly increase their ownership of the S&P 500 in the period between 1975 and 1983. As the ownership of the stock market increased as the number of index fund
This thesis includes both experimental and clinical projects. The experimental studies investigate pathophysiological aspects of ventricular longitudinal function and therapeutic hypothermia during acute myocardial infarction (AMI). The clinical projects investigate the ability of ventricular longitudinal function variables to predict mortality and morbidity in patients with heart failure and redu
Purpose: To prospectively compare nephrotoxicity and radiodensity of plasma hyperosmotic gadolinium chelates (attenuation-osmotic ratio of 1: 1) with those of plasma iso-osmotic iodine-based contrast media (attenuation-osmotic ratio of 3: 1 or 6: 1) after renal arteriography in ischemic porcine kidneys. Materials and Methods: The local animal care committee approved this study. The following contr
Thermoelectric elements have long been anticipated to challenge conventional solutions for converting heat to electricity. However, the revolution has been stalled due to the inability to reach efficiencies comparable to their conventional counterparts, while retaining a high output power. In this work we will model a thermoelectric element based on nanowires embedded with a quantum dot superlattice
Objectives: Recent evidence from the 7-year followup of the Pediatric Osteoporosis Prevention (POP) study indicates an inverse correlation between years of participation in a physical activity (PA) intervention and fracture risk in children. However, we could not see a statistically significant reduction in fracture risk, which urged for an extension of the intervention. Setting: The study was con
The common approach for constructing factor mimicking portfolios is to go long in assets with high loadings and to short-sell those with low loadings on some background factors. As a result portfolios containing stocks with low loading on the background factor receive negative betas against the corresponding mimicking portfolio. Thus, such portfolios appear as hedges against the background risk an
Objective: Following the Ross operation, pulmonary autografts tend to dilate over time. This study researches the fate of the pulmonary autograft - at 4.5 years following the modified Ross operation - with special reference to the impact of the modification on (a) pulmonary autograft dilatation, (b) the neo-aortic root geometry, (c) neo-aortic valve function and (d) the coronary artery reserve. Me
Background: To systematically review the association between knee abduction kinematics and kinetics during weight-bearing activities at baseline and the risk of future anterior cruciate ligament (ACL) injury. Methods: Systematic review and meta-analysis according to PRISMA guidelines. A search in the databases MEDLINE (PubMed), CINAHL, EMBASE and Scopus was performed. Inclusion criteria were prosp
Based on measurements of mould in 17 attics in the north of Sweden, 3 were chosen as a tentative validation of the MRD-model (Mould Resistance Design) for long periods of time (1961-2012). Comparing the measurements and the results from the simulations showed great differences regarding the mould growth depending on the simplifications used in the model. How the leakage was simulated and where the
Despite recent advances in lymphoma treatment, mantle cell lymphoma (MCL) remains incurable, and we are still unable to identify patients who will not benefit from the current standard of care. Here, we explore the prognostic value of recurrent genetic aberrations in diagnostic bone marrow (BM) specimens from 183 younger patients with MCL from the Nordic MCL2 and MCL3 trials, which represent curre
Ultraljudsvågor används i många olika tillämpningar, t.ex. som sonar i vatten och för fosterdiagnostik. De kan också användas för att göra mätningar på olika material för att bestämma materialets tjocklek eller ljudets hastighet i materialet. Ultraljudsvågorna produceras och detekteras med hjälp av piezoelektriska element, t.ex. polyvinylidenflourid (PVDF)-film eller så kallade PZT-element (blyzirUltrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. The ultrasonic waves are produced and detected by using piezoelectric elements based on e.g. Polyvinylidene fluoride (PVDF)-film or Lead Zirco
The Swedish household debt has been quite high and increasing for the past 30 years. In this thesis I tried to find the underlying reasons for the development in the long-run by using the Engle-Granger two-step model for co-integration but found that there was no co-integration between the household debt to disposable income ratio and the chosen variables. In the short-run analysis I de-trended al
