This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic. Conseque
The third generation (3G) cellular networks are starting to be deployed around the world. These networks are predicted to bring a vast number of IP enabled cellular terminals to the Internet. The limited address space of the current version of IP in the Internet, IPv4, has made the cellular industry decide to use IPv6 for these terminals. However, their success will largely depend on the availabil
A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. In this paper the performance of a number of classical CPSS designs has been evaluated at the center frequency of operation for all possible spherical incidence angles. The results are presented in a compact way using two dimensional contour plots to represent the return los
Superantigens (SAgs) are bacterial enterotoxins produced by Staphylococcus aureus. Staphylococcal enterotoxin type A (SEA), a staphylococcal superantigen, has been shown to bind to the cytokine signalling receptor glycoprotein 130 (gp130). The structural details, as well as the exact physiological role of this interaction, remain unclear. Here, we describe the structural details of the SEA–gp130 c
There are carcinogenic effects of sun exposure that increase the risk for skin cancer, especially for fair-skinned individuals. Therefore, there are recommendations to avoid sun exposure and to apply sun blockers. A more nuanced and balanced message for sun safety guidelines is now advocated. Despite an increased risk of death due to skin cancer, fair skinned women seem to have an overall survival
Social media facilitates the sharing of ideas, thoughts and information about older people and later life through online networks and communities in contemporary society. Social media content about older people has become important for understanding media representations of older people, but it has not been sufficiently studied. Recent studies suggest that older people are predominantly represente
The influence of growth conditions on the layer orientation, domain structure and crystal structure of gadolinium oxide (Gd2O3) on silicon (001) has been investigated. Gd2O3 was grown at low (250°C) and high (850°C) temperatures with different oxygen partial pressure as well as a temperature ramp up during growth. At low temperature, the cubic bixbyite type of crystal structure with space group Ia
Background: Understanding the micro-evolutionary response of populations to demographic declines is a major goal in evolutionary and conservation biology. In small populations, genetic drift can lead to an accumulation of deleterious mutations, which will increase the risk of extinction. However, demographic recovery can still occur after extreme declines, suggesting that natural selection may pu
Binding between protein molecules on contacting cells is essential in initiating and regulating several key biological processes. In contrast to interactions between molecules in solution, these events are restricted to the two-dimensional (2D) plane of the meeting cell surfaces. However, converting between the more commonly available binding kinetics measured in solution and the so-called 2D bind
This paper reconsiders the new mobilities paradigm and its relevance for the understanding of transport systems and behaviour. It argues that the mobilities field will gain from more systematically drawing on conceptual and empirical insights from psychology to complement insights as mostly derived from sociology, geography, innovation studies, anthropology, cultural studies and continental philos
Several neurodegenerative diseases cause loss of cortical neurons, leading to sensory, motor, and cognitive impairments. Studies in different animal models have raised the possibility that transplantation of human cortical neuronal progenitors, generated from pluripotent stem cells, might be developed into a novel therapeutic strategy for disorders affecting cerebral cortex. For example, we have s
During whey powder production, the feed is subjected to several heat treatments which can cause lactosylation of proteins. In this study, lactosylation of whey proteins was evaluated in spray-dried powders before and after storage by varying the native protein fraction as well as the serum protein/lactose ratio in the powders. The lactosylation of native α-lactalbumin and β-lactoglobulin in the po
