Severe obesity in adolescence negatively impacts upon health and wellbeing. Lifestyle modifications do not usually achieve a sufficient degree or durability of weight loss to mitigate the risk of medical complications. In recent years, metabolic and bariatric surgery (MBS), already a well-established treatment for adults with severe obesity, has emerged as an option in adolescents. Controlled stud

To alleviate worldwide dependence on fossil fuels for energy production and considerably reduce CO2 emissions, green energy sources and sustainable energy solutions are in high demand. Fuel cells are environmental-friendly electrochemical devices which may use clean fuels, e.g., green hydrogen gas, to generate electricity. Meanwhile, water electrolyzers provide an efficient strategy to produce gre

The great variety of earth's microorganisms and their functions are attributed to the heterogeneity of their habitats, but our understanding of the impact of this heterogeneity on microbes is limited at the microscale. In this study, we tested how a gradient of spatial habitat complexity in the form of fractal mazes influenced the growth, substrate degradation, and interactions of the bacterial st

Background: Screening for islet autoantibodies in children and adolescents identifies individuals who will later develop type 1 diabetes, allowing patient and family education to prevent diabetic ketoacidosis at onset and to enable consideration of preventive therapies. We aimed to assess whether islet autoantibody screening is effective for predicting type 1 diabetes in adolescents aged 10−18 yea

In the quest for the development of faster and more reliable technologies, the ability to control the propagation, confinement, and emission of light has become crucial. The design of guide mode resonators and perfect absorbers has proven to be of fundamental importance. In this project, we consider the shape optimization of a periodic dielectric slab aiming at efficient directional routing of lig

When Sweden left the gold standard on September 27, 1931, the Swedish government declared that the aim of monetary policy should be to stabilize the domestic purchasing power of the Swedish currency, the krona. With this step, price level targeting officially became for the first time the goal for a central bank. Soon after, the Riksbank (Bank of Sweden) sent a questionnaire to three prominent eco

Histological evaluation of tissue-engineered products, including hydrogels for cellular encapsulation, is a critical and invaluable tool for assessing the product across multiple stages of its lifecycle from manufacture to implantation. However, many tissue-engineered products are comprised of polymers and hydrogels which are not optimized for use with conventional methods of tissue fixation and h

Begreppet hybrid har formligen exploderat och man kan knappt läsa en tidning eller en produktannons i dag utan att stöta på detta ord. Åtskilliga studier inom ämnen som företagsekonomi, organisationssociologi och statsvetenskap säger sig också handla om just hybridorganisationer. Samtidigt uppstår då frågan vad begreppet egentligen tillför och om det bidrar till vår förståelse av organisationer. K

Innovation is generally viewed as something inherently good, a source of progress and prosperity in our society. But innovation can also have negative, unintended, and wasteful effects, if policies are misdirected and organizations pursue innovation to look good and convey a message, rather than to actually achieve improvements of technologies, services, and products. This book makes the case that

The subject of this thesis is what I call a literary friction in the dramatic. In my research project, my aim has been to deepen the understanding of this friction and to make it productive in transforming my own dramatic writing. This has resulted in two dramatic works, which are presented in the thesis. I distinguish two different qualities in my writing – the dramatic and the literary – that I The subject of this thesis is what I call a literary friction in the dramatic.

This thesis focuses on various aspects in terahertz quantum cascade lasers such as high temperature performances, electrical instabilities and chaos. In the first part of the thesis, an introduction to the topic and the non equilibrium Green's function package applied is given with particular emphasise on the inhomogeneous domain model and the chaos theory. In addition, new results regarding the h

Antenna current optimization has been used to derive physical bounds on antenna parameters such as Q-factor, radiation efficiency, gain, directivity, capacity, and radiation patterns. The success of the methodology is partly due to the assumption of absolute control of the antenna current in the antenna region which in practice producing an array antenna with multiple feeds. Details of the feed su
