Polyhydroxyalkylations for alkali-stable cationic polymers as hydroxide exchange membranes

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

Habitat complexity affects microbial growth in fractal maze

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

Islet autoantibody screening in at-risk adolescents to predict type 1 diabetes until young adulthood : a prospective cohort study

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

Shape optimization for the strong routing of light in periodic diffraction gratings

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

The First Practical Guide to Inflation Targeting

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

Formalin-free fixation and xylene-free tissue processing preserves cell-hydrogel interactions for histological evaluation of 3D calcium alginate tissue engineered constructs

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

Hybridorganisationer

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

Empty Innovation : Causes and Consequences of Society's Obsession with Entrepreneurship and Growth

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

Handlingarnas sken : om litterär slitning i det dramatiska

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.

Dynamical Analysis of Terahertz Quantum Cascade Lasers

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

Physical Bounds on Antennas with Feed Constraints

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

Neoliberally framed suffering in professionals and patients in palliative care settings – ’telling cases’ from an ethnographic multi-sited field study in Denmark

In western countries, palliative care is a part of the formal healthcare system, ruled by neoliberal, organisational ideas. This Danish study illuminates how nurses and patients with non-western immigrant backgrounds (inter)act in relation to encounters in palliative care settings. Two ‘telling’ cases were selected, based on interviews and participating observations from a multi-sited ethnographic
