Risk and vulnerability analyses can play important roles in the society’s proactive emergency management. This thesis addresses two ways of improving the analysis of risk and vulnerability analysis in this context. First, by developing methods for risk and vulnerability analysis of technical infrastructure networks and emergency response systems. Secondly, by aiming to improve practises related to
The aim of this study was to evaluate the effect of increasing the amount of time spent in physical education classes on bone mineral accrual and gain in bone size in prepubertal Danish children. A total of 135 boys and 108 girls, aged 6-8 years, were included in a school-based curriculum intervention program where the usual time spent in physical education classes was doubled to four classes (180
Orchestral playing is a central practice within Western European classical music. Previous research in the field of orchestral musicians’ learning and knowledge has mainly focused on students’ learning orchestral playing. Working conditions and work-related problems were also emphasized in previous studies. This thesis, however, focuses on professional orchestral musicians’ knowledge and learning.
Diode laser spectroscopy performed in the ultraviolet, visible and infrared spectral regions is presented. The accessible wavelength range for visible and near-infrared diode lasers is extended by the use of sum- and difference-frequency generation. Sum-frequency generation to the ultraviolet spectral region was employed using a blue and a red diode laser. Mercury spectroscopy was demonstrated wi
Previous studies have shown that the functional efficacy of intrastriatal transplants of fetal dopamine (DA) neurons in the rat Parkinson model depends on their ability to establish a new functional innervation of the denervated striatum. Here we report that the survival, growth, and function of the grafted DA neurons greatly depend on the severity of the lesion of the host nigrostriatal system. F
Popular Abstract in Swedish Moderna tillverkningsmaskiner är dyra och därför måste dess tillgänglighet och effektivitet ständigt hållas högt. Sådana resultat kan man inte åstadkomma utan tillämpning av en effektiv underhållsstrategi. Förutsättningar för att minska eller arrestera förslitnings hastighet på maskins delar och öka maskinlivslängden är stora vid användning av tillståndsövervakning, (TÖModern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. The main result reported in this thesis is that the rolling element bearing’s mean effective li
Abstract Modal behavior of a GoughâStewart Platform (GSP) is sensitive to several variables related to its inertia, damping and stiffness as well as its complex 3-D geometry. To optimize its dynamical performance, due to the complications of this system, it is crucial to have the equations parametrically at the neutral configuration. However, in the literature, no complete parametric solution to t
Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. The biosynthetic machinery controlling pheromone production compris
Popular Abstract in Swedish I cellen styrs allt av biomolekylernas förmåga till igenkänning och växelverkan med varandra. Molekylernas speciella egenskaper bygger upp kroppens alla komplicerade funktioner, till exempel immunförsvar, celldelning och muskelarbete. Interaktionerna mellan biomolekylerna kan vara av olika karaktär; de beskrivs som starka eller svaga (affinitet), långsamma eller snabba Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. Typically, weak interactions work in concert to trigger a biological response. The advantage with thi
The current fashion system known as Fast Fashion (FF) is responsible for severe environmental and social impacts. Fashion democratisation has increased consumers’ appetite for new trends, leading fashion companies to design an increasing number of collections per year. Manufacturing is outsourced to developing countries, where workers’ rights and working place regulations are hardly respected. Add
Housing affordability is an increasingly discussed political and economic issue. Recent research finds a negative relationship between housing affordability and mental health. Much of the prior research uses a ratio measurement for housing affordability. Using alternative measures of housing affordability, I re-examine the relationship between housing affordability and mental health. A fixed effec
Microbial enzyme diversity is a key to understand many ecosystem processes. Whole metagenome sequencing (WMG) obtains information on functional genes, but it is costly and inefficient due to large amount of sequencing that is required. In this study, we have applied a captured metagenomics technique for functional genes in soil microorganisms, as an alternative to WMG. Large-scale targeting of fun
The overall objective of this thesis was to investigate how CSR is approached by commercial banks in the U.S and Sweden respectively. We have therefore made a comparative analysis of the national differences in terms of CSR. This research was done by introducing and identifying dimensions that affect the CSR practices in each country. These dimensions have been analyzed based on the national busin

Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. In industrial manufacturing, aluminium alloys acquire their desired properties through specially designed heating processes. A common
This Master’s Thesis is the result of the collaboration between The Technical Faculty of Lund University and TÜV NORD Sweden AB. Focus has been directed towards the nuclear industry where this thesis is one of several other Master’s Theses regarding the dynamic modeling of a swing check valve. It is necessary for the nuclear industry to be able to model flow transients which involve the dynamic b
Deep renovation of the buildings is a key for sustainable development, however, the rate of deep renovation of residential buildings in the European Union (EU) is lower than what is required to meet the climate and energy goals. This paper analyses peculiarities and commonalities in market conditions and approaches to deep renovation of single-family (or detached) houses in Denmark and Sweden. The
