Injectable calcium sulphate and calcium phosphate bone substitutes

Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. The mechanical properties of this formulation were investigated by focussing on the factors affecting the compre

Binarity of Hipparcos Main Sequence Survey Stars

Hipparcos observations of double stars, mainly A and F primaries, aremodelled in order to check the statistics of double-star solutions inthe Hipparcos Catalogue and to set quantitative limits on binarydistributions. The number of companions per primary is estimated to 0.25+/-0.05 for semi-major axes from 1 to 10 AU, and to 0.43 +/-0.20 for therange 10--100 AU. The total multiplicity found is betw

Counting Thin Subgraphs via Packings Faster Than Meet-in-the-Middle Time

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

Towards Bridging the Gap Between Dalvik Bytecode and Native Code During Static Analysis of Android Applications

We propose a method for statically analyzing components that can be part of Android applications and which have not been very well analyzed so far, namely native libraries. As of now, third-party native code can be seen as a black box that can be fed input parameters from the Dalvik bytecode context, and output parameters can be returned back to the bytecode context. However, the native code can s

Abstract in Norwegian Moderne transplantasjonsteknologi har gjort menneskekroppen til en handelsvare. Den svenske etnologen Susanne Lundin har i mange år studert den internasjonale organhandelens uhyggelige og lukkede verden. I denne thrilleraktige reportasjeboken tar hun leseren med inn i en verden befolket av fortvilede vestlige pasienter som vil gjøre hva som helst for å skaffe seg for eksempe
