A nu-gap measure of distance between linear time-invariant systems is defined in terms of projections onto system graphs directly, without appealing to the existence of normalised strong graph representations as in the literature. A robust stability result is derived by exploiting an assumption on the compactness of a Hankel-type operator in a similar manner to recent developments on time-varying

Popular Abstract in Swedish The phenol oxidase “laccase” was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. However, its use in one of the oldest biotechnologies, i.e. the making of lacquerware in East-Asia, dates back to 5000-6000 BC. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes one elecLaccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product. Based on these highly desired mild oxidising conditio

Ducts of various geometrical cross sections appear extensively in engineering applications like heat exchangers. In the available literature analytical, numerical and experimental data are available for the friction factor and the Colburn factor for a variety of thermal boundary conditions. Results for fully developed cases are commonly available, but also for the thermally and hydrodynamically de

As a scholar of science and technology studies (a social science field that aims to understand the social processes of knowledge production), I focused the 4 years of my Ph.D. on studying how the academic landscape in which today’s postdoctoral life scientists develop their careers influences their working practices. Some of my results paint quite a grim picture of academic careers, baring the pro

This study examines “capabilities” in the conceptual and empirical literatures, to reveal whether indeterminateness of value is a problem within RBV, as suggested by the recent tautology debate. Conceptual studies typically relate to capabilities in terms of the desired ends of their use, whereas empirical studies conceptualize capabilities as composite constructs with desired ends and content-ori

Saccharomyces cerevisiae ferments hexoses in lignocellulosic hydrolysates under anaerobic conditions with high rates and ethanol yields. However, S. cerevisiae is naturally unable to utilize the pentose fraction of the hydrolysates. Xylose is the most abundant pentose sugar, and although recombinant S. cerevisiae strains capable of ethanolic xylose fermentation have been obtained through metabolic
