Several photosensitizers were screened for their tumour-marking ability using laserinduced fluorescence in Wistar/Furth rats bearing subcutaneous adenocarcinomas inoculated in muscle. Of the studied photosensitizers, dihaematoporphyrin ether appeared to exhibit the best tumour-demarcation properties. Polyhaematoporphyrin ester and tetrasulfonated phthalocyanine were almost as good although the flu

Popular Abstract in Swedish Istället för fred gav det kalla krigets slut upphov till nya säkerhetspolitiska utmaningar i form av inomstatliga konflikter. Under perioden 1989-2000 utkämpades 111 väpnade konflikter runt om i världen varav de flesta kan karakteriseras som inomstatliga, såsom inbördeskriget i Somalia, det våldsamma sammanbrottet i Jugoslavien, och folkmordet i Rwanda. Trots att både hThis study is concerned with tracing the process of how conflict prevention is moving from the realm of ideas to the field of action. Why is it that, despite historical as well as recent evidence of the infeasibility to prevent wars, the idea of conflict prevention has resurfaced to meet the challenge of the new wars of the post-Cold War era? The study investigates whether the growing interest in

Structural properties of the acidic proline rich protein PRP-1 of salivary origin in bulk solution and adsorbed onto a negatively charged surface have been studied by Monte Carlo simulations. A simple model system with focus on electrostatic interactions and short-ranged attractions among the uncharged amino acids has been used. In addition to PRP-1, some mutants were considered to assess the role

We discuss the main properties of the Galactic globular cluster (GC)blue straggler stars (BSSs), as inferred from our new catalog containingnearly 3000 BSSs. The catalog has been extracted from thephotometrically homogeneous V versus (B-V) color-magnitude diagrams(CMDs) of 56 GCs, based on Wide Field Planetary Camera 2 images of theircentral cores. In our analysis, we used consistent relative dist

Using a variational approach we prove an optimal nonlinear convolution inequality. This result is then applied to give criteria for finite-time blow-up of solutions to a nonlinear model equation in elasticity, improving considerably upon recent blow-up results.

Mesoporous thin films of cerium dioxide were prepared by using a copolymer surfactant (Pluronics 123) at ambient conditions in alcohol as a solvent. The material was produced via a direct calcination step, without the necessity of a gelling stage. The synthesised CeO2 matrix was crystalline with a high surface area. The solution height over the synthesis vessel before the calcination step was foun

A novel approach of applying priorities to memory allocation is presented and it is shown how this can be used to enhance the robustness of real-time applications. The proposed mechanisms can also be used to increase performance of systems with automatic memory management by limiting the amount of garbage collection work. A way of introducing priorities for memory allocation in a Java system witho
