This paper presents the results of ternary light charged particles from 252Cf spontenous fission source. The method DeltaE - E was applied to identify particle by a position sensitive telescope.The specific energy loss (DeltaE) measured using transmission type detector (thicknesses 150 μm ) ordered company Micron Semiconductors, while residual (E) Timepix with thicknesses 600 . It possible meas...

In the budding yeast Saccharomyces cerevisiae the Srs2/RadH DNA helicase promotes survival after ultraviolet (UV) irradiation, and has been implicated in DNA repair, recombination and checkpoint signalling following DNA damage. A second helicase, Sgs1, is the S.cerevisiae homologue of the human BLM and WRN proteins, which are defective in cancer predisposition and/or premature ageing syndromes....

The effect of detergents on giant unilamellar vesicles (GUVs) composed of phosphatidylcholine, sphingomyelin and cholesterol and containing liquid-ordered phase (l(o)) domains was investigated. Such domains have been used as models for the lipid rafts present in biological membranes. The studied detergents included lyso-phosphatidylcholine, the product of phospholipase A2 activity, as well as T...

In the frame of dependable neutron flux instrumentation development for Generation IV reactors, French Atomic and Alternative Energies Commission (CEA) investigates an innovative technology based on optical signal produced within a fission chamber. such gaseous detectors, neutrons interact with fissile material, releasing heavy ions in MeV range, eventually leading to spontaneous photons emissi...

The SUMO-dependent ubiquitin ligase Slx8 plays key roles in promoting genome stability, including the processing of trapped Topoisomerase I (Top1) cleavage complexes and removal of toxic SUMO conjugates. We show that it is the latter function that constitutes Slx8's primary role in fission yeast. The SUMO conjugates in question are formed by the SUMO ligase Pli1, which is necessary for limiting...
