This doctoral thesis takes as a starting point that geographical location remains fundamental to gain competitive advantage for some types of firms and activities even though economic activity in general has become more global. The region is seen as the key level in which the innovative capability of firms is shaped, coordinated and governed. This is in line with the regional innovation systems (R

Concerns regarding environmental issues such as greenhouse gas emissions and climate change have led to a shift within the research community and chemical and energy industry sectors for finding sustainable routes for producing fuels and chemicals from renewable resources, thereby minimizing our dependence on petroleum. The C3-chemical 3-hydroxypropionic acid has been identifed as a top candidate

This chapter illustrates how quantum chemical calculations can be used to elucidate structural and functional aspects of tetrapyrrole cofactors, focusing on porphyrins, cobalamins, coenzyme F430, and chlorophyll. A particular emphasis is put on the biochemical significance of axial ligands, which can tune the function of the tetrapyrroles. With the use of quantum chemical calculations, it is possi

The Integrated Design Process (IDP) was developed to streamline the design process of (solar integrated) low-energy buildings. One of the biggest differences with the traditional design process is the involvement of engineers and other consultants right from the early design stage. Although the IDP has been fully developed in theory with clear and general descriptions, the practical application of

New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. The physical traction limit set by the friction between the tires and the road

This study investigates online material published in reaction to a Science magazine report showing the absence of peer-review and editorial processes in a set of fee-charging open access journals in Biology. Quantitative and qualitative textual analyses are combined to map conceptual relations in these reactions; and to explore how understandings of scholarly communication and publishing relate to

Early growth and differentiation of the pancreatic endoderm is regulated by soluble factors from the pancreatic mesenchyme. Previously, we demonstrated that N-cadherin-deficient mice lack a dorsal pancreas, due to a critical role of N-cadherin in dorsal pancreatic mesenchymal cell survival. Here, we show that restoring cardiac and circulatory function in N-cadherin null mice by cardiac-specific ex

Today, the underlying theoretical and methodological foundations as well as implementations in the field of accessibility are largely based on plans, metrics and heuristics. There is an obvious tension between these norms and those of the overall spirit of the times, which leans heavily towards improvisations, diversity, and ever-changing affordances. The parallel evolution of human computer inter

Popular Abstract in English According to the International Diabetes Federation (IDF), 415 million people suffer from diabetes worldwide. Diabetes occurs when the pancreatic beta cells are no longer able to produce or properly use insulin. Insulin regulates blood glucose levels by enabling glucose uptake into cells, providing the body with energy. Elevated glucose levels cause damages to highly vasDiabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine. Using a MafA mutant mouse model, we show that MafA

Popular Abstract in Swedish Avhandlingens ämne är den mezuzah, en kapsel med texter ur 5 Mosebok, som bör fästas på dörrposterna i ett judiskt hem, i uppfyllande av budet i 5 Mos. 6:9/11:21: "och du skall skriva dem [dessa ord] på dörrposterna i ditt hus och på dina portar". Genom en översikt över rabbinska texter vilka behandlar budet att fästa en mezuzah på dörrposterna i hemmet inThe present study deals with different aspects of the mitsvat mezuzah in Rabbinic literature from the first to the sixteenth centuries, with some emphasis on the medieval sources. Through a charting of statements regarding the mezuzah as an object, and the mitsvat mezuzah and its fulfilment, an overview is given of the development of the mezuzah and the perception of it

Philosophers’ search for the best way to explain human actions has led many to accept a core psychological model that can be supplemented by other forms of action explanation when needed. Rather than settling for this model –where everything ultimately hinges on psychologicalexplanation – this paper argues for a pluralistic view. It does not claim that the psychological view is

Under efterkrigstiden skakades Stockholm återkommande av så kallade ungdomsupplopp, som av samtidens makthavare förstods som opolitiska, ja näst intill meningslösa i sin obegriplighet. Samtidigt låter händelserna oss resonera kring förhållandet mellan det offentliga rummet och människors kollektiva aktörskap. Genom att närma sig upploppen utifrån den politiska filosofen Jacques Rancières teorier o
