Glass sheets investigated regarding their Po-210 signal originating from indoor radon exposure will have a depth distribution down to about 100 nm. The geometrical probability of implantation into glass of glass-attached radon daughter activity in one alpha recoil event is 50%. A particulate layer on the glass sheet (dust, grease or other particles) will stop the alpha recoil nucleus partly or tot

Popular Abstract in Swedish Uppskattningsvis 30 % av befolkningen i industrialiserade länder drabbas varje år av förgiftningar och infektioner överförda via livsmedel och frekvensen i utvecklingsländer tros vara högre. För att kunna producera säker mat behövs mer kunskap om vilka egenskaper hos livsmedelsburna patogener, dvs. sjukdomsframkallande mikroorganismer som gör oss sjuka. Dessa egenskaperThe development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. In this thesis, the impact of environmental factors

We study the problem of discovering a manifold that best preserves information relevant to a nonlinear regression. Solving this problem involves extending and uniting two threads of research. On the one hand, the literature on sufficient dimension reduction has focused on methods for finding the best linear subspace for nonlinear regression; we extend this to manifolds. On the other hand, the lite

Vassilevska and Williams (STOC 2009) showed how to count simple paths on k vertices and matchings on k/2 edges in an n-vertex graph in time n^{k/2+O(1)}. In the same year, two different algorithms with the same runtime were given by Koutis and Williams (ICALP 2009), and Björklund et al. (ESA 2009), via nst/2+O(1)-time algorithms for counting t-tuples of pairwise disjoint sets drawn from a given fa

This article reflects on the aesthetics and visual culture of Nazism, as well as its troubling legacy to the world.

The birth and development of Gothicist ideas and their use in Spanish-Swedish contacts

Significant extensions to the high-spin excitation spectrum of the N = 91, 92, 93 isotopes Dy-157,Dy-158,Dy-159 have been achieved using the high-efficiency gamma-ray spectrometers Euroball and Gammasphere. These nuclei were populated via weak 3n or alpha xn exit channels in fusion evaporation reactions. In Dy-157, the yrast band has been extended to I-pi = (2)/(101+) (tentatively to (2)/(105+)) w
