In this work, surface enhanced Raman spectroscopy (SERS) was combined with dielectrophoresis (DEP) to realize a controllable in situ detection method of enhanced Raman signals from molecules in suspension environment. Polymer beads coated with gold nanoparticles were prepared as SERS ‘hot spot’ substrates. Several DEP electrode designs were evaluated and the stripe electrode succeeded in manipulat

The burden of mental disorders continues to grow and is now a leading cause of disability worldwide. The prevalence of mental disorders is unequal between population subgroups, and these disorders are associated with unfavourable consequences in social and economic conditions, health and survival. However, how the negative effects of mental disorders are distributed among population subgroups is lThe burden of mental disorders continues to grow and is now a leading cause of disability worldwide.

OBJECTIVE: Resistance to androgens has been suggested as a possible cause of male infertility. This hypothesis is based mainly on binding studies in genital skin fibroblasts but the molecular evidence is sparse. DESIGN: Molecular studies of the androgen receptor gene were performed in 10 azoo- or oligozoospermic men, precenting with clinical signs of low androgen activity - poor virilization and h

This study explores marketing messages promoting sustainable transport and reported motivation to reduce private car use within different segments. A stated preference survey targeting a sample of 1300 residents in Sweden was conducted, and exploratory factor analysis was used to identify underlying dimensions of a set of 19 marketing messages. Self-efficacy and collective efficacy were defined asThis study explores marketing messages promoting sustainable transport and reported motivation to reduce private car use within different segments.

Proper and efficient renovation requires understanding the behavior of existing buildings and of different building materials. Analyzing hygrothermal measurements in two case studies, one with and the other without an internally added thermal insulation system, enabled us to identify factors of critical importance for further assessment through simulations, and to validate a hygrothermal simulatio

Savanner är ett landskap med både träd och gräs som skapar en miljö som varken är skog eller gräsmark. Savanner tar upp cirka en sjättedel av världens totala landyta och de har på grund av detta en stor betydelse för den globala kolbalansen. De flesta savanner har två distinkta säsonger, en regnperiod då vegetationen grönskar samt en period med torka utan nederbörd. Detta gör att förändringar i deSavannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. Most savannahs are characterized with two distinct seasons, one dry season and one wet season where a maj

Factors influencing the effect of pilot-injection on main-injection combustion were investigated using heat release analysis in a heavy-duty diesel engine fuelled with standard diesel fuel, and included the effect of those factors on engine performance and emissions.Combinations of pilot injection parameters i.e. pilot start of injection, pilot mass, pilot-main injection separation, and rail pressFactors influencing the effect of pilot-injection on main-injection combustion were investigated using heat release analysis in a heavy-duty diesel engine fuelled with standard diesel fuel, and included the effect of those factors on engine performance and emissions.Combinations of pilot injection parameters i.e. pilot start of injection, pilot mass, pilot-main injection separation, and rail press

The advent of novel agents for multiple myeloma (MM) is cause for a re-examination of the incidence of second primary malignancies (SPMs). We examined the SPM rate in MM patients who were enrolled in the prospective observational CALM (Collaboration to Collect Autologous Transplant outcome in Lymphoma and Myeloma) study. Between 2008 and 2012, 3204 patients with MM underwent a first autologous hem

Ashbya gossypii is a homothallic, flavinogenic, filamentous ascomycete that starts overproduction of riboflavin and fragments its mycelium quantitatively into spore producing sporangia at the end of a growth phase. Mating is not required for sporulation and the standard homothallic laboratory strain is a MATa strain. Here we show that ectopic expression of Saccharomyces cerevisiae MATα2 in A. goss

The rat hepatic artery responds to acetylcholine (ACh) with an endothelium‐dependent relaxation, which is unaffected by nitric oxide (NO) synthase and cyclooxygenase inhibition. The purpose of this study was to investigate whether the NO‐independent relaxation is caused by hyperpolarization of the smooth muscle cells. In vessels with endothelium ACh induced a hyperpolarization in the presence of 0

BACKGROUND: Global inequalities in access to health care are reflected in differences in cancer survival. The CONCORD programme was designed to assess worldwide differences and trends in population-based cancer survival. In this population-based study, we aimed to estimate survival inequalities globally for several subtypes of childhood leukaemia.METHODS: Cancer registries participating in CONCORD

Introduction: To reduce local recurrence rates when performing anterior resection in rectal cancer surgery Swedish national guidelines recommend rectal washout. This study aimed to describe current Swedish practice of rectal washout. Methods: Questionnaires were sent to Swedish surgical departments performing rectal cancer surgery. Results: Thirty-five units performed open rectal cancer surgery, a

OBJECTIVES: The aim of this study was to investigate whether there is an association between socioeconomic status, occupation and hospitalization for Parkinson's disease (PD).METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first adult hospitalizations for PD diagnosed in Sweden during the study period from 1987 t

Den här avhandlingen berör två olika forskningsområden som är relaterade till fysiken för nanosystem. Det första området rör kvantkorrelationer och sammanflätning mellan elektroner i nanosystem, med ett särskilt fokus på hur man kan generera elektronisk orbital sammanflätning på tidsskalor mycket kortare än dekoherenstiden och hur man kan göra detektionen av sammanflätning enklare experimentellt. This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes. The second topic concerns heat
