A dry release method for fabrication of suspended nanostructures is presented. The technique has been combined with an anti-stiction treatment for fabrication of nanocantilever based nanoelectromechanical systems (NEMS). The process combines a dry release method, using a supporting layer of photoresist which is removed using oxygen ashing in a reactive ion etcher (RIE), with CHF3 plasma induced de

With the increased pressure and challenges of economic, environmental, and social character, the need for innovations (including both the generation and adoption of innovations) that can be implemented in supply chains increases. A number of novel concepts focusing on intelligent logistics and packaging systems are being developed and tested in the food industry, all over the world. Several of the

Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces

A range of third-sector organizations, among them diaconal actors, contributes actively to thewelfare mix in the Nordic countries. The independence of these actors is in constant tension with thefact that the organizations are dependent on resources from the surrounding society. Norms andrules influence nonprofit organizations to adopt practices that change the organization, in thedirection of an

Viking Age silver is a useful tool for tracing various aspects of the society. Contact networks, trade organization, society structure, economic variation etc. This paper concentrates on the so-called Permian rings, which appear in Scandinavian silver hoards from Early Viking Age. Their main concentration is, however, in the regions west of the Ural Mountains in Russia. As the rings found in Russi

This study demonstrates that a cytotoxic serum reactivity not requiring the presence of complement appears in the sera of patients with acute myelogenous leukemia. The reaction is detected upon short‐term incubation of sera in vitro with autochthonous mononuclear white blood cells from peripheral venous blood of patients at the acute stage of the disease. This reactivity was demonstrated in 18/18

Despite the recent clinical success of T cell checkpoint inhibition targeting the CTLA-4 and PD-1 pathways, many patients either fail to achieve objective responses or they develop resistance to therapy. In some cases, poor responses to checkpoint blockade have been linked to suboptimal CD28 costimulation and the inability to generate and maintain a productive adaptive anti-tumor immune response.

In a growing global corporate bond market, insights and understanding of the markets pricing mechanisms becomes increasingly important to investors. While previous research on credit risk has mainly focused on the American bond market, European bonds remain rather unexplored in academia. In this article, we investigate the explanatory power of a family of credit risk models - called structural modThis thesis empirically tests the explanatory power of structural models on the European corporate bond market. Using new evaluation methods, including LASSO and gradient boosting regression, we can provide an in-depth assessment of the models’ shortcomings. With these tools we show that the structural models tend to systematically overstate or understate the spread due to an oversensitivity to le

Microorganisms can be used for production of pharmaceutical substances. With the introduction of gene technology, it is possible to transfer information from one organism to the other, thereby making the receiving organism capable of producing substances that it did not so before. This development is very important for e.g. production of therapeutic proteins However, when using living organisms fo

The importance of entrepreneurship in our society is the way it stimulate the markets through alertness to opportunities, and being creational of new opportunity-ideas. However, entrepreneurship is usually constrained by normative, regulative and cognitive mechanisms that enforces and forms the basis on which the entrepreneur operates. This leads us to the primary question of this thesis: to ident
