Nature contains an endless supply of natural products and has for long been a source of inspiration for the pharmaceutical industry. Many of the drugs currently in clinical use originate from natural products. Paclitaxel, the active substance in the anti cancer medicine Taxol, was first isolated from the Pacific yew tree (Taxus brevifolia) in the early 1960s during a screening program for novel an

Tailbiting trellis representations of linear block codes with an arbitrary sectionalization of the time axis are studied. A new lower bound on the maximal state complexity of an arbitrary tailbiting code is derived. The asymptotic behavior of the derived bound is investigated. Some new tailbiting representations for linear block codes of rates R=1/c, c=2,3,4 are presented

Rezension des Bandes „Die Rousseau-Frage – ökologisch definiert”, herausgegeben von Udo E. SimonisDer Band ist hervorgegangen aus einer öffentlichen Ausschreibung aus Anlass des zehnjährigen Jubiläums des „Jahrbuchs Ökologie” im Jahre 2001 zur Fragestellung: „Hat der Fortschritt der Wissenschaften und Künste dazu beigetragen, die Umwelt zu schützen und zu bewahren?” Diese Thematik lehnt sich an di

In this paper, some fundamental problems concerning the verification of fire safety engineering designs based on performance-based building regulations are discussed. It can be questioned if the approach taken by many practitioners today is sufficient to fulfil the requirements laid out in the building code, i.e. society’s demand for fire safety. Examples of this deficiency are that interdependenc

Swedish textile art is often described as highly successful and as part of an appreciated tradition. But there are some interesting points to be made from looking at the subject as an Art Historian with a gender- and genre-perspective. First of all the textile material is closely linked to notions of femininity. The textile material is also persistently placed within the craft sphere. Secondly, th

This paper concerns the unifying framework to strictly contractive extension problems, which is usually referred to as the band method. The solution to the so-called strictly contractive extension problem in this abstract framework, when applied to a certain concrete case, yields a complete characterization of solutions to the sub-optimal Nehari problem. The sub-optimal Hankel norm approximation p

A model describing the oxygen dynamics in an E. coli fed-batch cultivation is presented. In a linearised version the parameters are estimated and validated with good results. The model is used to discuss the guidelines for feed controller tuning derived in Åkesson 2001.
