This chapter provides a synthesis of three earlier published studies (Garmy et al. 2012a; Garmy et al. 2012b; Garmy et al. 2013) (survey I) as well as previously unpublished results from a survey conducted in 2013 among students aged 16 (survey II). Objective: The aim was to investigate the effects of sleep, television use and texting and computer habits on overweight, enjoyment of school and fee

In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. In my work, I have work tried to find out what makes such speci

Semiconductor nanowires have many properties which makes them interesting for future electronic devices. The fact that they have very small diameters allow them to combine different III-V materials into heterostructures, and makes it possible to grow them on Si substrates which are the basis of nearly all current semiconductor technology. It also allows them to adopt the wurtzite crystal structure

This paper provides an extensive analysis of the demand for alcohol in terms of total quantity and quantity subdivided into frequency and intensity demand. The analysis compares across alcohol types (beer, wine and spirits), alcohol drinking pattern (average drinker vs. binge drinkers) and also how these decisions differ across gender. The analysis is based on a large sample of cross-sectional dat

Background Improving knowledge of obstetric danger signs and promoting birth preparedness practices are strategies aimed at enhancing utilization of skilled care in low-income countries. The aim was to explore the association between knowledge of obstetric danger signs and birth preparedness among recently delivered women in south-western Uganda. Methods The study included 764 recently delivered

In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length. We are therefore able to investigate friction in th

In this presentation will be given an up-date of the status of epitaxially grown III-V nanowires, from the perspective of growth, processing, physics and applications in the areas of nanoelectronics and nanophotonics

This book uses the case of the Artists' House, a cultural center in Tehran, to place the socio-political implications of Iran's social and cultural transformation in a local-global context. The author examines the bipolar dimension of openness to change versus conservation and the role of these values in Iranian society generally as well as in the context of everyday life in Tehran. The text addre

The incidence of Hodgkin lymphoma has increased among adolescents and young adults in recent decades, but the relevant risk factors in early life are still unknown. A national cohort study was conducted of 3,571,574 individuals born in Sweden in 19732008 and followed up for Hodgkin lymphoma incidence through 2009, to examine perinatal and family risk factors for Hodgkin lymphoma in childhood throu
