- Events with at least two high transverse momentum leptons (electrons or muons) are studied using the H1 and ZEUS detectors at HERA with an integrated luminosity of 0.94 fb(-1). The observed numbers of events are in general agreement with the Standard Model predictions. Seven di- and tri-lepton events are observed in e(+)p collision data with a scalar sum of the lepton transverse momenta above 100 GeV while 1.94 +/- 0.17 events are expected. Such events are not observed in e(-)p collisions for which 1.19 +/- 0.12 are predicted. Total visible and differential di-electron and di-muon photoproduction cross sections are extracted in a restricted phase space dominated by photon-photon collisions.

- Saturated straight- and branched-chain 3-hydroxy fatty acids (3-OH FAs) of 10-18 carbon chain lengths were determined in saliva from 27 individuals with chronic periodontitis and 18 healthy individuals by using gas chromatography-tandem mass spectrometry. Of the 14 different 3-OH FAs detected, 3-OH-C-i17:0 was the most abundant in the periodontitis samples while 3-OH-C-14:0 was the most abundant in the healthy individuals. Considering the relative percentages of 3-OH-C-12:0, 3-OH-C-14:0, 3OH-C-i17:0, and 3-OH-C-17:0, 95.6% of all cases were correctly classified as healthy individuals or periodontitis patients by means of discriminant analysis. The sensitivity, specificity, positive predictive value and negative predictive value of 3-OH FA analysis in diagnosing peridontitis were, respectively, 0.92, 1.00, 1.00, and 0.90. The results indicate that 3-OH FA analysis of saliva samples is a useful diagnostic method in chronic periodontitis.

Futuristic back-end of the nuclear fuel cycle with the partitioning of minor actinides

Tidskriftsartikel (refereegranskat)abstract
- For future back-end of the nuclear fuel cycle, the partitioning of minor actinides: Np, Am and Cm, followed by their transmutation will minimize importantly the radiotoxicity of nuclear glass waste. In this paper, the research done in France and in Europe will be presented: (i) partitioning of Np by modified PUREX process, (ii) partitioning of Am and Cm by the DIAMEX and SANEX hydrometallurgical processes.
