This paper presents and discusses results from the research project LETS 2050 that studies the governance challenges of a transition to a low-carbon transport and energy system in Sweden by 2050 (www.lets2050.se ). A key starting point of the project was that a low carbon transition is technically possible and economically feasible, while the main challenge is political. At the moment there is an
Disturbances on utilities, such as steam and cooling water, often cause large economic losses at industrial sites. Utilities are often shared between production areas, and a disturbance on a utility is therefore likely to affect a large part of the production site. In addition, production areas are often coupled by the product at the site. Obtaining a dynamic model of a site, with respect to utili
n the many-body theory of conduction electrons in a metal the single-particle spectrum is described not simply by the energy versus momentum relation as in band theory but by a function that describes the actual shape of the spectrum for a given momentum and has an appreciable spread in energy. Calculations of the spectral strength function for electrons in a uniform electron gas are described, wh
A low-weight aerosol sampler has been developed and tested. Internal losses for both sub-micron and large particles ( < 10 tam) are of the order of 5 %. The size fractionation patterns indicate that the sampler may be used to collect a separate respirable fraction in good agreement with the BMRC standard and a coarse fraction deternuned by the inlet design.
