It has become increasingly obvious during the last two decades that a multitude of cellular processes are highly dependent on adequate levels of polyamines (1–6). Too high concentrations of the polyamines are toxic to the cell and may induce cell death or apoptosis (7). On the other hand, too low concentrations may negatively affect anabolic events, such as the synthesis of DNA, RNA, and protein,
This book chapter is a feminist reading of Richard Wagner's opera Lohengrin.
The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved. Empirically this b
A new control strategy for steam pressure control inthe drying cylinders during web breaks is presented. The developmentis performed using a new physical model implemented inSimulink. The goal of the control strategy is that thecylinder temperatures are retained whenthe production is restarted after the web break.
Vad avses med begreppet ”sociala rörelser”? Och, vad är det som skiljer de nya sociala rörelserna från de gamla sociala rörelserna? Hur skall man förstå globaliseringsprotesternas uppkomst, och då speciellt i relation till kapitalismen? I denna artikel diskuteras det faktum att många sociala rörelser idag tenderar att sammanstråla i en kritik av kapitalismen. Denna kapitalismkritik är såväl klassi
Due to the increasing interest of producing power from renewable and non-conventional resources, organic Rankine cycles are finding their place in today’s thermal energy mix. The main influencers on the efficiency of an organic Rankine cycle are the working fluid and the expander. Therefore most of the research done up to date turns around the selection of the best performance working media and th
In this article the medialization of everyday life is discussed, as it appears in the norwegian novelist Jan Kjaerstads "Förföraren" (The Seducer). I mainly focus upon the intermedia aspects between literature and other art and media forms, such as TV, film, music, etc. Another aspect discussed in the article is the cluster of connections between Norway/Scandinavia and the rest of the world, which
This paper presents a procedure for assigning zone data to links in the context of a Geographic Information System (GIS) environment. This may be used for several applications; the one motivating this paper is the need to approximate how much secondary traffic is accessing the main street network from adjacent zones. This will then be used in models to predict the number of accidents on the main r
