Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

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

Laminar Friction Factors and Colburn Factors for Ducts with Advanced Boundary Conditions

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

Life at the bottleneck

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

Tautology, Managerial Relevance, and Predictive Power of the RBV: The Neglected Content Dimension of Organizational Capabilities

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

Genetic Traits Beneficial for Xylose Utilization by Recombinant Saccharomyces cerevisiae

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

Ten Years Of Sustainable Construction Aspects From A North And A South Perspective – A Review From Sustainable Building Conferences 1998-2007.

This paper is about, from a North and South different perspective, how the international focus of sustainable construction issues has changed over the past ten years. It is a review from four different international and regional sustainable building conferences between 1998 and 2007. The paper is mostly based of the first author's notes from the conferences, especially from the plenary sessions an
