Popular Abstract in English Popular science Microbial cells are small and difficult to handle in industrial processes, especially if they are to be reused subsequent batches. In order to make them easier to handle, these cells can be attached to a solid support, by so-called immobilization. This provides particles of sizes that are easy to filter and reuse. However, immobilization is associated wiAbstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide

The presentation gives examples of industrial adaptive controllers and of industrial applications of adaptive control. Adaptive control algorithms are found in single-loop controllers as well as in distributed control systems. Several commercial systems are available today. The given applications are mainly from the process control area. Adaptive control has many good aspects, but it also requires

Interactions between physical bodies constantly affect their properties. This thesis presents a theoretical study on the effects of interaction in few-body nanowire quantum dots. The focus is to a large extent on a phenomenon called Wigner localization, and how this, as well as other interaction effects, can be identified in an experiment by transport spectroscopy and by thermopower measurements.

In November 2009 a Swedish twitterer died in a car accident. Even though @Just_Tea wasn’t a celebrity, condolences and displays of public mourning stacked up from her followers and the Swedish blogosphere. However, there was also disapproving voices, criticizing the public displays of grief of someone whom few had met and even fewer could call friend. The criticism and the subsequent discussions o

Wave propagation of transient electromagnetic waves in time-varying media is considered. The medium, which is assumed to be inhomogeneous and dispersive, lacks invariance under time translations. The spatial variation of the medium is assumed to be in the depth coordinate, i.e., it is stratified. The constitutive relations of the medium is a time integral of a generalized susceptibility kernel and

In an industrial plant, availability is an important factor since increased availability often gives an increase of final production, which in many cases means an increased profit for the company. The purpose of using buffer tanks is to increase the availability either by separating production units from each other or by minimizing flow variations. However, the methods for achieving this goal is n
