Human complement component C4 was irreversibly inactivated by low concentrations of methylamine at slightly alkaline pH. The inactivated C4 molecules lost the ability to bind to EAC1 cells but retained th capacity to participate in the formation of classical pathway C3 convertase in the fluid phase. 14C-methylamine was incorporated into the alpha-chain at a ratio of 1 mol methylamine per mol C4.

This paper presents an interactive tool which allows to study the problem of systems with delays. The developed tool provides several examples in order to compare PI control and Smith Predictor approaches for processes with delay. Robustness problems due to presence of model uncertainties can also be studied, as well as other control structures to face the different problems that the original Smit

A major problem when using software platforms to produce a variety of products relates to keeping a high quality of the platform throughout the development of the products. For a software platform development to be successful, it is essential to master the quality issues when managing and designing the platform. This thesis presents approaches that enable efficient use of the soft-ware platform

An important measure for climate change mitigation is reduction of energy use in buildings worldwide. To decrease the energy use of a building in a Nordic climate, increased thermal resistance of the building envelope is a suitable measure. Adding more insulation in combination with climate change may increase the risk of mold growth within the building envelope. This study evaluates hygrothermal

This paper presents some preliminary empirical reflexions about rural development in North East Argentina at the light of the recent socio-economic and political changes. The processes of decentralization that have taken place in the country during the decade of 1990 illustrate the complexity of rural development strategies at local level and the necessity to create policies to take into account t

Video data and the tools for automated analysis have a great potential to be used in road traffic research, particularly road safety. In this project a video dataset is built and made public so that researchers can evaluate their algorithms on it. The dataset focuses on the traffic research applications (data from real research projects) and provides recordings of the traffic scenes, meta-data, ca

REXEBIS is the charge breeder of the REX-ISOLDE postaccelerator. Radioactive 1+ ions produced at ISOLDE are accumulated, phase-space cooled and bunched in REXTRAP, and thereafter injected into the EBIS with an energy of up to 60 keV. The REXEBIS produced the first charge bred ions in August 2001 and has been running nearly non-stop from September to December 2001. It has delivered stable 39K10+ an

Laser-induced fluorescence (LIF) spectra of a bush and numerous branches of Chinese Longjing tea were investigated remotely with lidar techniques. The intensity ratio between the far red fluorescence (FRF) and red fluorescence (RF) due to the chlorophyll content of the tea branches were analyzed to study the growth conditions in different villages around Hangzhou, China. Dried Longjing tea leaves
