To study adhesion in flexible laminates, standardised peel tests are commonly used where macroscopic measurements, e.g. peel force versus peel arm displacement, are extracted. However, insights into the adhesion mechanisms at the microscopic scale are limited. This study has developed a framework for determining peel arm geometry parameter evolution and deformation in packaging material laminates.
Laser Activated Electronics Transistors are often considered the most revolutionary electrical devices of this century, attributed as the building block of all modern technology. It is these tiny devices that control the flow of electrons in all your electronics. In your computer alone, there are hundreds of millions of these transistors, all working together in a complex circuit. Previously, impr
Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. The characterization of ultrashort laser pThe human eye can clearly observe movements as fast as around 0.1 seconds long, but how can we observe the movement that is way too fast for the human eye? For example, you can barely read any labels from a really fast moving formula 1 car. However, if we use a camera which can act faster than the human eye, we can capture the images of the moving object. When a camera takes a picture, it records
The purpose of this thesis was to investigate the possibility of application of the cluster based rural development approach in Armenia to promote its structural transformation. Case study was selected as a research methodology, and both qualitative and quantitative methods were employed. Analysis of the key findings from the ‘field’, i.e. - the potential cluster, shows that rural households pract
Kenya as a country is known for its ethnic diversity and boasts of over 42 ethnic/tribes communities that for many years have lived together in harmony and respect for each other. In the face of this harmonious cohesion between the different communities, there have been sporadic threats on issues of resource distribution and political differences that have cultivated ethnic/tribal hatred and fight
Population aging has tremendous economic consequences and generates an unprecedented pressure on the welfare state. As the number and share of ‘dependent’ people grows, the state struggles to finance pensions and health-related costs. In this optic, Sweden is no exception: the mean age of the population, life expectancy and share of people above 65 continuously increase – which warrants the focus
This thesis compares the wildfire evacuation simulation programme, WUI-NITY, against real-world data by analysing and comparing three wildfire events of the past. The wildfire events were all limited to be within the state of California and was further analysed based on the available quality of data derived of the chosen database. The goal with this thesis was to setup simulations based on the evi
Currently I am studying the realization of two large-scale experimental natural science facilities: The European Spallation Source (ESS) and MAX IV (a synchrotron facility). They are examples of New Big Science (NBS) – facilities where substantial amounts of resources and hopes are tied to making future scientific discoveries. Both facilities will host more than 20 different instruments, catering Feminist technoscience studies (FTS) comprise a major strand of STS. Constituted by a diverse and heterogeneous set of projects and publications, these studies make politicised, impassioned contributions to contemporary critical thought about science, technology and medicine. They are also driven by a powerful desire for justice (see Reardon et al in Catalyst Vol 1 No 1). Building on century-old t
Nitrous oxide (N2O) is a greenhouse gas formed during biological wastewater treatment under aerobic and anoxic conditions. Two reasons for high N2O emissions are low oxygen concentration during nitrification and low carbon/nitrogen-ratio during denitrification. In this full-scale study of N2O emissions from a sequencing batch reactor for treating digester supernatant, the oxygen concentration was
Background Following surgical repair of aortic coarctation (CoA) there is a risk for restenosis (reCoA), particularly in the first year of life. It was the aim of this study to identify reCoA risk factors by analyzing postoperative pre-discharge echocardiograms. Methods Retrospective analysis of echocardiograms of children born operated for CoA in Sweden 2011-2017. Results 253 children were includ
Peatlands play an important role in the global carbon cycle as they contain a large soil carbon stock. However, current climate change could potentially shift peatlands from being carbon sinks to carbon sources. Remote sensing methods provide an opportunity to monitor carbon dioxide (CO2) exchange in peatland ecosystems at large scales under these changing conditions. In this study, we developed ePeatlands play an important role in the global carbon cycle as they contain a large soil carbon stock.

Objectives. Despite accumulating research on yoga and its positive impact on both physiological and psychological health, it is still unclear how yoga improves health. Two central components of yoga: yogic breathing and mindfulness, may be important mechanisms by which individuals learn to cope with their daily stressors, and thereby reduce their risk of developing stress-related illness.

Popular Abstract in English In this thesis I will compare and contrast two willow warbler subspecies, each with different migratory programs that meet in Central Sweden forming a migratory divide and hybrid zone. These migratory programs differ in the direction and distance traveled during migration. The "northern" willow warblers migrate south-southeast through the Balkan Peninsula to winter in eIn this thesis I will compare and contrast the two willow warbler subspecies (Phylloscopus trochilus trochilus and P. t. acredula) with differing migratory phenotypes (or "migratype") in the context of their migratory divide and hybrid zone in central Sweden. Their migratory programs differ in the direction and distance traveled during migration. The "northern" willow warblers migrate south-southe
Background: Invasive infections with non-beta-haemolytic streptococci (NBHS) is quite common and presents the clinicians with difficulties regarding which patients are at risk for infective endocarditis (IE). The HANDOC score was developed to identify patients with NBHS bacteraemia who are at low risk of IE. This study was conducted to validate HANDOC in an external cohort. Methods: Patients with
Unlike what is usually taken for granted in semiotics, communication, in the sense of semiosis, does not essentially depend on transport and/or recoding. Instead, it consists in the creation of an artefact, with the additional setting of a task of interpretation. This task may be set by the addressee, just as likely as by the addresser. In making this suggestion, we are inspired by Husserlean phen

Cases of successful developmental states constrained by democratic institutions pose challenges to the literature on the political economy of late development. On the one hand, the dominant view is that successful developmental states tend to rely on authority-based coordination mechanisms—corporatist arrangements, labor repression, professional bureaucracies insulated from popular pressures—to soCases of successful developmental states constrained by democratic institutions pose challenges to the literature on the political economy of late development.
