conclusions our results demonstrated no significant correlation between the ird5 lifespan and the trehalose concentration. likewise, the correlation between lifespan extension, trehalose accumulation, and cellular resistance to hydrogen peroxide was not significant. results the lifespan of the ird5 mutant was significantly longer that of either the ird11 mutant or the wild type cells. under rep...

A model based on the macroscopic-microscopic approach for calculating the fission-fragment properties is presented. Using this model, a large set of experimental data measured in lowand high-energy fission can be reproduced using one and same set of model parameters.

The results of model calculations on nuclide yields produced in selected scenarios using reactions with U nuclei are presented. The calculation combines the modelling of the initial reaction mechanism, the deexcitation process including the fission competition with the prediction of the nuclide production in the fission of excited U and all daughter nuclei produced in the evaporation cascade. T...

The unimolecular decomposition of 2,5-dimethylfuran (DMF), a promising next-generation biofuel, was studied at the CBS-QB3 level of theory. As most of its decomposition routes remain unknown, a large number of pathways were explored: initial C-H bond fission, biradical ring opening, H-atom and CH(3)-group transfers involving carbene intermediates. Based on the computed potential energy surfaces...

the radiophotoluminescence property of some materials makes it possible to use them for dosimetry purposes. the silver activated metaphoshate glass 1 as an rpl dosimeter when exposed to x. or y radiations , forms fluorescent centers with long lived states ( metastate ). the silver ions (ag+) in unirradiated state produces vacancies when energy is supplied by irradiation the release of electrons...

In order to improve on current prompt fission neutron spectrum measurements, a gamma multiplicity tagging method was developed at the Rensselaer Polytechnic Institute Gearttner Linear Accelerator Center. This method involves using a coincidence requirement on an array of BaF2 gamma detectors to determine the timing of a fission event. This allows for much larger fission samples to be used due t...
