- Future raw material shortage, high price levels and environmental regulations requires increased reuse of materials andcomponents. This will substantially influence conditions for both manufacturing and recycling industries, which need toinnovate their business models. Our hypothesis is that an integrated co-operation between organizations within these industries, employing symbiotic business models will increase the profitability and reduce the total environmental impact. Findings from interaction with manufacturing and recycling industries using a business model framework as baseline are presented. Results indicate that profit and decreased environmental effects can be achieved through symbiotic business models, but further development and implementation is needed.

- Studies have shown that crashworthiness of cars addressing fatal and serious injuries has generally improved over time. However, the development regarding injuries leading to medical impairment has not been shown to the same extent. The objective was to investigate the development of Whiplash associated Disorders (WAD) leading to long-term consequences for adult front seat occupants and for children 0-12 years of age in cars introduced at different year intervals and in different impact directions separated for gender. Long-term consequences were defined as occupants with WAD symptoms at least one month and those resulting in medical impairment. The developments were studied for cars divided into intervals according to year of introduction and for frontal, side and rear-end impacts. All adult occupants (35 611) and 76% of all children (973) reporting WAD between 1998 and 2008 were selected. Approximately 2% of the children reporting initial symptoms sustained medical impairment. The corresponding figure for adult occupants was approximately 10%. Between the introduction years 1980-84 and 2000-04 the proportions of adult occupants with medical impairment dropped by approximately 70% (both males and females) in frontal and rear-end crashes, while the reduction in lateral impacts appears to be somewhat lower. For children there is a tendency that the proportion of WAD increases in newer models in frontal collisions. The result indicates that protecting children facing forward deserves more attention from the automotive industry and governmental bodies.

- The dynamic space- and frequency dependent response of a Molten Salt Reactor (MSR) to stationary perturbations is investigated in a simple analytical model. The Green's function of the system is investigated in the general case of arbitrary fuel recirculation velocity and in the limiting case of infinite fuel velocity which permits closed form solutions both in the static and dynamic case. It is found that the amplitude of the induced noise is generally higher and the domain of the point kinetic behaviour valid up to higher frequencies than in a corresponding traditional system. This is due to the differing behaviour of the delayed neutron precursors as compared to the traditional case. The MSR equations are not self-adjoint and the adjoint equation and adjoint function have to be constructed, which is also done here. Finally the space-dependent neutron noise, induced by propagating perturbations of the absorption cross section is calculated. A number of interesting properties that are relevant to full size MSRs are found and interpreted. The results are consistent with those in traditional systems but the domains of various behaviour regimes (point kinetic, space dependent etc.) is shifted to higher frequencies or system sizes.

Konferensbidrag (refereegranskat)abstract
- We present an overview of the recent developments of a cryogenic 2-14 GHz feed system for the Very Long Baseline Interferometry 2010 (VLBL2010) project. The developments include a new balun feeding network, a new circular Eleven feed, system noise temperature modeling and testing, integration with different low noise amplifiers (LNAs), and cryostat design and integration.
